Additionaly, it provides script-level access to basic thread synchronization primitives, like mutexes and condition variables. [section COMMANDS] This section describes commands for creating and destroying threads and sending scripts to threads for evaluation. [list_begin definitions] [call [cmd thread::create] [opt -joinable] [opt -preserved] [opt script]] This command creates a thread that contains a Tcl interpreter. The Tcl interpreter either evaluates the optional [option script], if specified, or it waits in the event loop for scripts that arrive via the [cmd thread::send] command. The result, if any, of the optional [option script] is never returned to the caller. The result of [cmd thread::create] is the ID of the thread. This is the opaque handle which identifies the newly created thread for all other package commands. The handle of the thread goes out of scope automatically when thread is marked for exit (see the [cmd thread::release] command below). [para] If the optional [option script] argument contains the [cmd thread::wait] command the thread will enter into the event loop. If such command is not found in the [option script] the thread will run the [option script] to the end and exit. In that case, the handle may be safely ignored since it refers to a thread which does not exists any more at the time when the command returns. [para] Using flag [option -joinable] it is possible to create a joinable thread, i.e. one upon whose exit can be waited upon by using [cmd thread::join] command. Note that failure to join a thread created with [option -joinable] flag results in resource and memory leaks. [para] Threads created by the [cmd thread::create] cannot be destroyed forcefully. Consequently, there is no corresponding thread destroy command. A thread may only be released using the [cmd thread::release] and if its internal reference count drops to zero, the thread is marked for exit. This kicks the thread out of the event loop servicing and the thread continues to execute commands passed in the [option script] argument, following the [cmd thread::wait] command. If this was the last command in the script, as usualy the case, the thread will exit. [para] It is possible to create a situation in which it may be impossible to terminate the thread, for example by putting some endless loop after the [cmd thread::wait] or entering the event loop again by doing an vwait-type of command. In such cases, the thread may never exit. This is considered to be a bad practice and should be avoided if possible. This is best illustrated by the example below: [example { # You should never do ... set tid [thread::create { package require Http thread::wait vwait forever ; # <-- this! }] }] The thread created in the above example will never be able to exit. After it has been released with the last matching [cmd thread::release] call, the thread will jump out of the [cmd thread::wait] and continue to execute commands following. It will enter [cmd vwait] command and wait endlessly for events. There is no way one can terminate such thread, so you wouldn't want to do this! [para] Each newly created has its internal reference counter set to 0 (zero), i.e. it is unreserved. This counter gets incremented by a call to [cmd thread::preserve] and decremented by a call to [cmd thread::release] command. These two commands implement simple but effective thread reservation system and offer predictable and controllable thread termination capabilities. It is however possible to create initialy preserved threads by using flag [option -preserved] of the [cmd thread::create] command. Threads created with this flag have the initial value of the reference counter of 1 (one), and are thus initially marked reserved. [call [cmd thread::preserve] [opt id]] This command increments the thread reference counter. Each call to this command increments the reference counter by one (1). Command returns the value of the reference counter after the increment. If called with the optional thread [option id], the command preserves the given thread. Otherwise the current thread is preserved. [para] With reference counting, one can implement controlled access to a shared Tcl thread. By incrementing the reference counter, the caller signalizes that he/she wishes to use the thread for a longer period of time. By decrementing the counter, caller signalizes that he/she has finished using the thread. [call [cmd thread::release] [opt -wait] [opt id]] This command decrements the thread reference counter. Each call to this command decrements the reference counter by one (1). If called with the optional thread [option id], the command releases the given thread. Otherwise, the current thread is released. Command returns the value of the reference counter after the decrement. When the reference counter reaches zero (0), the target thread is marked for termination. You should not reference the thread after the [cmd thread::release] command returns zero or negative integer. The handle of the thread goes out of scope and should not be used any more. Any following reference to the same thread handle will result in Tcl error. [para] Optional flag [option -wait] instructs the caller thread to wait for the target thread to exit, if the effect of the command would result in termination of the target thread, i.e. if the return result would be zero (0). Without the flag, the caller thread does not wait for the target thread to exit. Care must be taken when using the [option -wait], since this may block the caller thread indefinitely. This option has been implemented for some special uses of the extension and is deprecated for regular use. Regular users should create joinable threads by using the [option -joinable] option of the [cmd thread::create] command and the [cmd thread::join] to wait for thread to exit. [call [cmd thread::id]] This command returns the ID of the current thread. [call [cmd thread::errorproc] [opt procname]] This command sets a handler for errors that occur in scripts sent asynchronously, using the [option -async] flag of the [cmd thread::send] command, to other threads. If no handler is specified, the current handler is returned. The empty string resets the handler to default (unspecified) value. An uncaught error in a thread causes an error message to be sent to the standard error channel. This default reporting scheme can be changed by registering a procedure which is called to report the error. The [arg procname] is called in the interpreter that invoked the [cmd thread::errorproc] command. The [arg procname] is called like this: [example { myerrorproc thread_id errorInfo }] [call [cmd thread::cancel] [opt -unwind] [arg id] [opt result]] This command requires Tcl version 8.6 or higher. [para] Cancels the script being evaluated in the thread given by the [arg id] parameter. Without the [option -unwind] switch the evaluation stack for the interpreter is unwound until an enclosing catch command is found or there are no further invocations of the interpreter left on the call stack. With the [option -unwind] switch the evaluation stack for the interpreter is unwound without regard to any intervening catch command until there are no further invocations of the interpreter left on the call stack. If [arg result] is present, it will be used as the error message string; otherwise, a default error message string will be used. [call [cmd thread::unwind]] Use of this command is deprecated in favour of more advanced thread reservation system implemented with [cmd thread::preserve] and [cmd thread::release] commands. Support for [cmd thread::unwind] command will dissapear in some future major release of the extension. [para] This command stops a prior [cmd thread::wait] command. Execution of the script passed to newly created thread will continue from the [cmd thread::wait] command. If [cmd thread::wait] was the last command in the script, the thread will exit. The command returns empty result but may trigger Tcl error with the message "target thread died" in some situations. [call [cmd thread::exit] [opt status]] Use of this command is deprecated in favour of more advanced thread reservation system implemented with [cmd thread::preserve] and [cmd thread::release] commands. Support for [cmd thread::exit] command will dissapear in some future major release of the extension. [para] This command forces a thread stuck in the [cmd thread::wait] command to unconditionaly exit. The thread's exit status defaults to 666 and can be specified using the optional [arg status] argument. The execution of [cmd thread::exit] command is guaranteed to leave the program memory in the unconsistent state, produce memory leaks and otherwise affect other subsytem(s) of the Tcl application in an unpredictable manner. The command returns empty result but may trigger Tcl error with the message "target thread died" in some situations. [call [cmd thread::names]] This command returns a list of thread IDs. These are only for threads that have been created via [cmd thread::create] command. If your application creates other threads at the C level, they are not reported by this command. [call [cmd thread::exists] [arg id]] Returns true (1) if thread given by the [arg id] parameter exists, false (0) otherwise. This applies only for threads that have been created via [cmd thread::create] command. [call [cmd thread::send] [opt -async] [opt -head] [arg id] [arg script] [opt varname]] This command passes a [arg script] to another thread and, optionally, waits for the result. If the [option -async] flag is specified, the command does not wait for the result and it returns empty string. The target thread must enter it's event loop in order to receive scripts sent via this command. This is done by default for threads created without a startup script. Threads can enter the event loop explicitly by calling [cmd thread::wait] or any other relevant Tcl/Tk command, like [cmd update], [cmd vwait], etc. [para] Optional [option varname] specifies name of the variable to store the result of the [arg script]. Without the [option -async] flag, the command returns the evaluation code, similarily to the standard Tcl [cmd catch] command. If, however, the [option -async] flag is specified, the command returns immediately and caller can later [cmd vwait] on [opt varname] to get the result of the passed [arg script] [example { set t1 [thread::create] set t2 [thread::create] thread::send -async $t1 "set a 1" result thread::send -async $t2 "set b 2" result for {set i 0} {$i < 2} {incr i} { vwait result } }] In the above example, two threads were fed work and both of them were instructed to signalize the same variable "result" in the calling thread. The caller entered the event loop twice to get both results. Note, however, that the order of the received results may vary, depending on the current system load, type of work done, etc, etc. [para] Many threads can simultaneously send scripts to the target thread for execution. All of them are entered into the event queue of the target thread and executed on the FIFO basis, intermingled with optional other events pending in the event queue of the target thread. Using the optional [opt -head] switch, scripts posted to the thread's event queue can be placed on the head, instead on the tail of the queue, thus being executed in the LIFO fashion. [call [cmd thread::broadcast] [arg script]] This command passes a [arg script] to all threads created by the package for execution. It does not wait for response from any of the threads. [call [cmd thread::wait]] This enters the event loop so a thread can receive messages from the [cmd thread::send] command. This command should only be used within the script passed to the [cmd thread::create]. It should be the very last command in the script. If this is not the case, the exiting thread will continue executing the script lines past the [cmd thread::wait] which is usually not what you want and/or expect. [example { set t1 [thread::create { # # Do some initialization work here # thread::wait ; # Enter the event loop }] }] [call [cmd thread::eval] [opt {-lock mutex}] [arg arg] [opt {arg ...}]] This command concatenates passed arguments and evaluates the resulting script under the mutex protection. If no mutex is specified by using the [opt {-lock mutex}] optional argument, the internal static mutex is used. [call [cmd thread::join] [arg id]] This command waits for the thread with ID [arg id] to exit and then returns it's exit code. Errors will be returned for threads which are not joinable or already waited upon by another thread. Upon the join the handle of the thread has gone out of scope and should not be used any more. [call [cmd thread::configure] [arg id] [opt option] [opt value] [opt ...]] This command configures various low-level aspects of the thread with ID [arg id] in the similar way as the standard Tcl command [cmd fconfigure] configures some Tcl channel options. Options currently supported are: [option -eventmark] and [option -unwindonerror]. [para] The [option -eventmark] option, when set, limits the number of asynchronously posted scripts to the thread event loop. The [cmd {thread::send -async}] command will block until the number of pending scripts in the event loop does not drop below the value configured with [option -eventmark]. Default value for the [option -eventmark] is 0 (zero) which effectively disables the checking, i.e. allows for unlimited number of posted scripts. [para] The [option -unwindonerror] option, when set, causes the target thread to unwind if the result of the script processing resulted in error. Default value for the [option -unwindonerror] is 0 (false), i.e. thread continues to process scripts after one of the posted scripts fails. [call [cmd thread::transfer] [arg id] [arg channel]] This moves the specified [arg channel] from the current thread and interpreter to the main interpreter of the thread with the given [arg id]. After the move the current interpreter has no access to the channel any more, but the main interpreter of the target thread will be able to use it from now on. The command waits until the other thread has incorporated the channel. Because of this it is possible to deadlock the participating threads by commanding the other through a synchronous [cmd thread::send] to transfer a channel to us. This easily extends into longer loops of threads waiting for each other. Other restrictions: the channel in question must not be shared among multiple interpreters running in the sending thread. This automatically excludes the special channels for standard input, output and error. [para] Due to the internal Tcl core implementation and the restriction on transferring shared channels, one has to take extra measures when transferring socket channels created by accepting the connection out of the [cmd socket] commands callback procedures: [example { socket -server _Accept 2200 proc _Accept {s ipaddr port} { after idle [list Accept $s $ipaddr $port] } proc Accept {s ipaddr port} { set tid [thread::create] thread::transfer $tid $s } }] [call [cmd thread::detach] [arg channel]] This detaches the specified [arg channel] from the current thread and interpreter. After that, the current interpreter has no access to the channel any more. The channel is in the parked state until some other (or the same) thread attaches the channel again with [cmd thread::attach]. Restrictions: same as for transferring shared channels with the [cmd thread::transfer] command. [call [cmd thread::attach] [arg channel]] This attaches the previously detached [arg channel] in the current thread/interpreter. For already existing channels, the command does nothing, i.e. it is not an error to attach the same channel more than once. The first operation will actualy perform the operation, while all subsequent operation will just do nothing. Command throws error if the [arg channel] cannot be found in the list of detached channels and/or in the current interpreter. [call [cmd thread::mutex]] Mutexes are most common thread synchronization primitives. They are used to synchronize access from two or more threads to one or more shared resources. This command provides script-level access to exclusive and/or recursive mutexes. Exclusive mutexes can be locked only once by one thread, while recursive mutexes can be locked many times by the same thread. For recursive mutexes, number of lock and unlock operations must match, otherwise, the mutex will never be released, which would lead to various deadlock situations. [para] Care has to be taken when using mutexes in an multithreading program. Improper use of mutexes may lead to various deadlock situations, especially when using exclusive mutexes. [para] The [cmd thread::mutex] command supports following subcommands and options: [list_begin definitions] [call [cmd thread::mutex] [method create] [opt -recursive]] Creates the mutex and returns it's opaque handle. This handle should be used for any future reference to the newly created mutex. If no optional [opt -recursive] argument was specified, the command creates the exclusive mutex. With the [opt -recursive] argument, the command creates a recursive mutex. [call [cmd thread::mutex] [method destroy] [arg mutex]] Destroys the [arg mutex]. Mutex should be in unlocked state before the destroy attempt. If the mutex is locked, the command will throw Tcl error. [call [cmd thread::mutex] [method lock] [arg mutex]] Locks the [arg mutex]. Locking the exclusive mutex may throw Tcl error if on attempt to lock the same mutex twice from the same thread. If your program logic forces you to lock the same mutex twice or more from the same thread (this may happen in recursive procedure invocations) you should consider using the recursive mutexes. [call [cmd thread::mutex] [method unlock] [arg mutex]] Unlocks the [arg mutex] so some other thread may lock it again. Attempt to unlock the already unlocked mutex will throw Tcl error. [list_end] [para] [call [cmd thread::rwmutex]] This command creates many-readers/single-writer mutexes. Reader/writer mutexes allow you to serialize access to a shared resource more optimally. In situations where a shared resource gets mostly read and seldom modified, you might gain some performace by using reader/writer mutexes instead of exclusive or recursive mutexes. [para] For reading the resource, thread should obtain a read lock on the resource. Read lock is non-exclusive, meaning that more than one thread can obtain a read lock to the same resource, without waiting on other readers. For changing the resource, however, a thread must obtain a exclusive write lock. This lock effectively blocks all threads from gaining the read-lock while the resource is been modified by the writer thread. Only after the write lock has been released, the resource may be read-locked again. [para] The [cmd thread::rwmutex] command supports following subcommands and options: [list_begin definitions] [call [cmd thread::rwmutex] [method create]] Creates the reader/writer mutex and returns it's opaque handle. This handle should be used for any future reference to the newly created mutex. [call [cmd thread::rwmutex] [method destroy] [arg mutex]] Destroys the reader/writer [arg mutex]. If the mutex is already locked, attempt to destroy it will throw Tcl error. [call [cmd thread::rwmutex] [method rlock] [arg mutex]] Locks the [arg mutex] for reading. More than one thread may read-lock the same [arg mutex] at the same time. [call [cmd thread::rwmutex] [method wlock] [arg mutex]] Locks the [arg mutex] for writing. Only one thread may write-lock the same [arg mutex] at the same time. Attempt to write-lock same [arg mutex] twice from the same thread will throw Tcl error. [call [cmd thread::rwmutex] [method unlock] [arg mutex]] Unlocks the [arg mutex] so some other thread may lock it again. Attempt to unlock already unlocked [arg mutex] will throw Tcl error. [list_end] [para] [call [cmd thread::cond]] This command provides script-level access to condition variables. A condition variable creates a safe environment for the program to test some condition, sleep on it when false and be awakened when it might have become true. A condition variable is always used in the conjuction with an exclusive mutex. If you attempt to use other type of mutex in conjuction with the condition variable, a Tcl error will be thrown. [para] The command supports following subcommands and options: [list_begin definitions] [call [cmd thread::cond] [method create]] Creates the condition variable and returns it's opaque handle. This handle should be used for any future reference to newly created condition variable. [call [cmd thread::cond] [method destroy] [arg cond]] Destroys condition variable [arg cond]. Extreme care has to be taken that nobody is using (i.e. waiting on) the condition variable, otherwise unexpected errors may happen. [call [cmd thread::cond] [method notify] [arg cond]] Wakes up all threads waiting on the condition variable [arg cond]. [call [cmd thread::cond] [method wait] [arg cond] [arg mutex] [opt ms]] This command is used to suspend program execution until the condition variable [arg cond] has been signalled or the optional timer has expired. The exclusive [arg mutex] must be locked by the calling thread on entrance to this command. If the mutex is not locked, Tcl error is thrown. While waiting on the [arg cond], the command releases [arg mutex]. Before returning to the calling thread, the command re-acquires the [arg mutex] again. Unlocking the [arg mutex] and waiting on the condition variable [arg cond] is done atomically. [para] The [option ms] command option, if given, must be an integer specifying time interval in milliseconds the command waits to be signalled. Otherwise the command waits on condition notify forever. [para] In multithreading programs, there are many situations where a thread has to wait for some event to happen until it is allowed to proceed. This is usually accomplished by repeatedly testing a condition under the mutex protection and waiting on the condition variable until the condition evaluates to true: [example { set mutex [thread::mutex create] set cond [thread::cond create] thread::mutex lock $mutex while {} { thread::cond wait $cond $mutex } # Do some work under mutex protection thread::mutex unlock $mutex }] Repeated testing of the condition is needed since the condition variable may get signalled without the condition being actually changed (spurious thread wake-ups, for example). [list_end] [list_end] [section DISCUSSION] The fundamental threading model in Tcl is that there can be one or more Tcl interpreters per thread, but each Tcl interpreter should only be used by a single thread which created it. A "shared memory" abstraction is awkward to provide in Tcl because Tcl makes assumptions about variable and data ownership. Therefore this extension supports a simple form of threading where the main thread can manage several background, or "worker" threads. For example, an event-driven server can pass requests to worker threads, and then await responses from worker threads or new client requests. Everything goes through the common Tcl event loop, so message passing between threads works naturally with event-driven I/O, [cmd vwait] on variables, and so forth. For the transfer of bulk information it is possible to move channels between the threads. [para] For advanced multithreading scripts, script-level access to two basic synchronization primitives, mutex and condition variables, is also supported.

It allows you to post jobs to worker threads and wait for their completion. The threadpool implementation is Tcl event-loop aware. That means that any time a caller is forced to wait for an event (job being completed or a worker thread becoming idle or initialized), the implementation will enter the event loop and allow for servicing of other pending file or timer (or any other supported) events. [section COMMANDS] [list_begin definitions] [call [cmd tpool::create] [opt options]] This command creates new threadpool. It accepts several options as key-value pairs. Options are used to tune some threadpool parameters. The command returns the ID of the newly created threadpool. [para] Following options are supported: [list_begin options] [opt_def -minworkers [arg number]] Minimum number of worker threads needed for this threadpool instance. During threadpool creation, the implementation will create somany worker threads upfront and will keep at least number of them alive during the lifetime of the threadpool instance. Default value of this parameter is 0 (zero). which means that a newly threadpool will have no worker threads initialy. All worker threads will be started on demand by callers running [cmd tpool::post] command and posting jobs to the job queue. [opt_def -maxworkers [arg number]] Maximum number of worker threads allowed for this threadpool instance. If a new job is pending and there are no idle worker threads available, the implementation will try to create new worker thread. If the number of available worker threads is lower than the given number, new worker thread will start. The caller will automatically enter the event loop and wait until the worker thread has initialized. If. however, the number of available worker threads is equal to the given number, the caller will enter the event loop and wait for the first worker thread to get idle, thus ready to run the job. Default value of this parameter is 4 (four), which means that the threadpool instance will allow maximum of 4 worker threads running jobs or being idle waiting for new jobs to get posted to the job queue. [opt_def -idletime [arg seconds]] Time in seconds an idle worker thread waits for the job to get posted to the job queue. If no job arrives during this interval and the time expires, the worker thread will check the number of currently available worker threads and if the number is higher than the number set by the [option minthreads] option, it will exit. If an [option exitscript] has been defined, the exiting worker thread will first run the script and then exit. Errors from the exit script, if any, are ignored. [para] The idle worker thread is not servicing the event loop. If you, however, put the worker thread into the event loop, by evaluating the [cmd vwait] or other related Tcl commands, the worker thread will not be in the idle state, hence the idle timer will not be taken into account. Default value for this option is unspecified. [opt_def -initcmd [arg script]] Sets a Tcl script used to initialize new worker thread. This is usually used to load packages and commands in the worker, set default variables, create namespaces, and such. If the passed script runs into a Tcl error, the worker will not be created and the initiating command (either the [cmd tpool::create] or [cmd tpool::post]) will throw error. Default value for this option is unspecified, hence, the Tcl interpreter of the worker thread will contain just the initial set of Tcl commands. [opt_def -exitcmd [arg script]] Sets a Tcl script run when the idle worker thread exits. This is normaly used to cleanup the state of the worker thread, release reserved resources, cleanup memory and such. Default value for this option is unspecified, thus no Tcl script will run on the worker thread exit. [list_end] [para] [call [cmd tpool::names]] This command returns a list of IDs of threadpools created with the [cmd tpool::create] command. If no threadpools were found, the command will return empty list. [call [cmd tpool::post] [opt -detached] [opt -nowait] [arg tpool] [arg script]] This command sends a [arg script] to the target [arg tpool] threadpool for execution. The script will be executed in the first available idle worker thread. If there are no idle worker threads available, the command will create new one, enter the event loop and service events until the newly created thread is initialized. If the current number of worker threads is equal to the maximum number of worker threads, as defined during the threadpool creation, the command will enter the event loop and service events while waiting for one of the worker threads to become idle. If the optional [opt -nowait] argument is given, the command will not wait for one idle worker. It will just place the job in the pool's job queue and return immediately. [para] The command returns the ID of the posted job. This ID is used for subsequent [cmd tpool::wait], [cmd tpool::get] and [cmd tpool::cancel] commands to wait for and retrieve result of the posted script, or cancel the posted job respectively. If the optional [opt -detached] argument is specified, the command will post a detached job. A detached job can not be cancelled or waited upon and is not identified by the job ID. [para] If the threadpool [arg tpool] is not found in the list of active thread pools, the command will throw error. The error will also be triggered if the newly created worker thread fails to initialize. [call [cmd tpool::wait] [arg tpool] [arg joblist] [opt varname]] This command waits for one or many jobs, whose job IDs are given in the [arg joblist] to get processed by the worker thread(s). If none of the specified jobs are ready, the command will enter the event loop, service events and wait for the first job to get ready. [para] The command returns the list of completed job IDs. If the optional variable [opt varname] is given, it will be set to the list of jobs in the [arg joblist] which are still pending. If the threadpool [arg tpool] is not found in the list of active thread pools, the command will throw error. [call [cmd tpool::cancel] [arg tpool] [arg joblist] [opt varname]] This command cancels the previously posted jobs given by the [arg joblist] to the pool [arg tpool]. Job cancellation succeeds only for job still waiting to be processed. If the job is already being executed by one of the worker threads, the job will not be cancelled. The command returns the list of cancelled job IDs. If the optional variable [opt varname] is given, it will be set to the list of jobs in the [arg joblist] which were not cancelled. If the threadpool [arg tpool] is not found in the list of active thread pools, the command will throw error. [call [cmd tpool::get] [arg tpool] [arg job]] This command retrieves the result of the previously posted [arg job]. Only results of jobs waited upon with the [cmd tpool::wait] command can be retrieved. If the execution of the script resulted in error, the command will throw the error and update the [var errorInfo] and [var errorCode] variables correspondingly. If the pool [arg tpool] is not found in the list of threadpools, the command will throw error. If the job [arg job] is not ready for retrieval, because it is currently being executed by the worker thread, the command will throw error. [call [cmd tpool::preserve] [arg tpool]] Each call to this command increments the reference counter of the threadpool [arg tpool] by one (1). Command returns the value of the reference counter after the increment. By incrementing the reference counter, the caller signalizes that he/she wishes to use the resource for a longer period of time. [call [cmd tpool::release] [arg tpool]] Each call to this command decrements the reference counter of the threadpool [arg tpool] by one (1).Command returns the value of the reference counter after the decrement. When the reference counter reaches zero (0), the threadpool [arg tpool] is marked for termination. You should not reference the threadpool after the [cmd tpool::release] command returns zero. The [arg tpool] handle goes out of scope and should not be used any more. Any following reference to the same threadpool handle will result in Tcl error. [call [cmd tpool::suspend] [arg tpool]] Suspends processing work on this queue. All pool workers are paused but additional work can be added to the pool. Note that adding the additional work will not increase the number of workers dynamically as the pool processing is suspended. Number of workers is maintained to the count that was found prior suspending worker activity. If you need to assure certain number of worker threads, use the [option minworkers] option of the [cmd tpool::create] command. [call [cmd tpool::resume] [arg tpool]] Resume processing work on this queue. All paused (suspended) workers are free to get work from the pool. Note that resuming pool operation will just let already created workers to proceed. It will not create additional worker threads to handle the work posted to the pool's work queue. [list_end] [section DISCUSSION] Threadpool is one of the most common threading paradigm when it comes to server applications handling a large number of relatively small tasks. A very simplistic model for building a server application would be to create a new thread each time a request arrives and service the request in the new thread. One of the disadvantages of this approach is that the overhead of creating a new thread for each request is significant; a server that created a new thread for each request would spend more time and consume more system resources in creating and destroying threads than in processing actual user requests. In addition to the overhead of creating and destroying threads, active threads consume system resources. Creating too many threads can cause the system to run out of memory or trash due to excessive memory consumption. [para] A thread pool offers a solution to both the problem of thread life-cycle overhead and the problem of resource trashing. By reusing threads for multiple tasks, the thread-creation overhead is spread over many tasks. As a bonus, because the thread already exists when a request arrives, the delay introduced by thread creation is eliminated. Thus, the request can be serviced immediately. Furthermore, by properly tuning the number of threads in the thread pool, resource thrashing may also be eliminated by forcing any request to wait until a thread is available to process it.

tpool(n) 2.8 "Tcl Threading"

Name

tpool - Part of the Tcl threading extension implementing pools of worker threads.

Description

This package creates and manages pools of worker threads. It allows you to post jobs to worker threads and wait for their completion. The threadpool implementation is Tcl event-loop aware. That means that any time a caller is forced to wait for an event (job being completed or a worker thread becoming idle or initialized), the implementation will enter the event loop and allow for servicing of other pending file or timer (or any other supported) events.

COMMANDS

tpool::create ?options?

This command creates new threadpool. It accepts several options as key-value pairs. Options are used to tune some threadpool parameters. The command returns the ID of the newly created threadpool.

Following options are supported:

-minworkers number

Minimum number of worker threads needed for this threadpool instance. During threadpool creation, the implementation will create somany worker threads upfront and will keep at least number of them alive during the lifetime of the threadpool instance. Default value of this parameter is 0 (zero). which means that a newly threadpool will have no worker threads initialy. All worker threads will be started on demand by callers running tpool::post command and posting jobs to the job queue.

-maxworkers number

Maximum number of worker threads allowed for this threadpool instance. If a new job is pending and there are no idle worker threads available, the implementation will try to create new worker thread. If the number of available worker threads is lower than the given number, new worker thread will start. The caller will automatically enter the event loop and wait until the worker thread has initialized. If. however, the number of available worker threads is equal to the given number, the caller will enter the event loop and wait for the first worker thread to get idle, thus ready to run the job. Default value of this parameter is 4 (four), which means that the threadpool instance will allow maximum of 4 worker threads running jobs or being idle waiting for new jobs to get posted to the job queue.

-idletime seconds

Time in seconds an idle worker thread waits for the job to get posted to the job queue. If no job arrives during this interval and the time expires, the worker thread will check the number of currently available worker threads and if the number is higher than the number set by the minthreads option, it will exit. If an exitscript has been defined, the exiting worker thread will first run the script and then exit. Errors from the exit script, if any, are ignored.

The idle worker thread is not servicing the event loop. If you, however, put the worker thread into the event loop, by evaluating the vwait or other related Tcl commands, the worker thread will not be in the idle state, hence the idle timer will not be taken into account. Default value for this option is unspecified.

-initcmd script

Sets a Tcl script used to initialize new worker thread. This is usually used to load packages and commands in the worker, set default variables, create namespaces, and such. If the passed script runs into a Tcl error, the worker will not be created and the initiating command (either the tpool::create or tpool::post) will throw error. Default value for this option is unspecified, hence, the Tcl interpreter of the worker thread will contain just the initial set of Tcl commands.

-exitcmd script

Sets a Tcl script run when the idle worker thread exits. This is normaly used to cleanup the state of the worker thread, release reserved resources, cleanup memory and such. Default value for this option is unspecified, thus no Tcl script will run on the worker thread exit.

tpool::names

This command returns a list of IDs of threadpools created with the tpool::create command. If no threadpools were found, the command will return empty list.

tpool::post ?-detached? ?-nowait? tpool script

This command sends a script to the target tpool threadpool for execution. The script will be executed in the first available idle worker thread. If there are no idle worker threads available, the command will create new one, enter the event loop and service events until the newly created thread is initialized. If the current number of worker threads is equal to the maximum number of worker threads, as defined during the threadpool creation, the command will enter the event loop and service events while waiting for one of the worker threads to become idle. If the optional ?-nowait? argument is given, the command will not wait for one idle worker. It will just place the job in the pool's job queue and return immediately.

The command returns the ID of the posted job. This ID is used for subsequent tpool::wait, tpool::get and tpool::cancel commands to wait for and retrieve result of the posted script, or cancel the posted job respectively. If the optional ?-detached? argument is specified, the command will post a detached job. A detached job can not be cancelled or waited upon and is not identified by the job ID.

If the threadpool tpool is not found in the list of active thread pools, the command will throw error. The error will also be triggered if the newly created worker thread fails to initialize.

tpool::wait tpool joblist ?varname?

This command waits for one or many jobs, whose job IDs are given in the joblist to get processed by the worker thread(s). If none of the specified jobs are ready, the command will enter the event loop, service events and wait for the first job to get ready.

The command returns the list of completed job IDs. If the optional variable ?varname? is given, it will be set to the list of jobs in the joblist which are still pending. If the threadpool tpool is not found in the list of active thread pools, the command will throw error.

tpool::cancel tpool joblist ?varname?

This command cancels the previously posted jobs given by the joblist to the pool tpool. Job cancellation succeeds only for job still waiting to be processed. If the job is already being executed by one of the worker threads, the job will not be cancelled. The command returns the list of cancelled job IDs. If the optional variable ?varname? is given, it will be set to the list of jobs in the joblist which were not cancelled. If the threadpool tpool is not found in the list of active thread pools, the command will throw error.

tpool::get tpool job

This command retrieves the result of the previously posted job. Only results of jobs waited upon with the tpool::wait command can be retrieved. If the execution of the script resulted in error, the command will throw the error and update the errorInfo and errorCode variables correspondingly. If the pool tpool is not found in the list of threadpools, the command will throw error. If the job job is not ready for retrieval, because it is currently being executed by the worker thread, the command will throw error.

tpool::preserve tpool

Each call to this command increments the reference counter of the threadpool tpool by one (1). Command returns the value of the reference counter after the increment. By incrementing the reference counter, the caller signalizes that he/she wishes to use the resource for a longer period of time.

tpool::release tpool

Each call to this command decrements the reference counter of the threadpool tpool by one (1).Command returns the value of the reference counter after the decrement. When the reference counter reaches zero (0), the threadpool tpool is marked for termination. You should not reference the threadpool after the tpool::release command returns zero. The tpool handle goes out of scope and should not be used any more. Any following reference to the same threadpool handle will result in Tcl error.

tpool::suspend tpool

Suspends processing work on this queue. All pool workers are paused but additional work can be added to the pool. Note that adding the additional work will not increase the number of workers dynamically as the pool processing is suspended. Number of workers is maintained to the count that was found prior suspending worker activity. If you need to assure certain number of worker threads, use the minworkers option of the tpool::create command.

tpool::resume tpool

Resume processing work on this queue. All paused (suspended) workers are free to get work from the pool. Note that resuming pool operation will just let already created workers to proceed. It will not create additional worker threads to handle the work posted to the pool's work queue.

DISCUSSION

Threadpool is one of the most common threading paradigm when it comes to server applications handling a large number of relatively small tasks. A very simplistic model for building a server application would be to create a new thread each time a request arrives and service the request in the new thread. One of the disadvantages of this approach is that the overhead of creating a new thread for each request is significant; a server that created a new thread for each request would spend more time and consume more system resources in creating and destroying threads than in processing actual user requests. In addition to the overhead of creating and destroying threads, active threads consume system resources. Creating too many threads can cause the system to run out of memory or trash due to excessive memory consumption.

A thread pool offers a solution to both the problem of thread life-cycle overhead and the problem of resource trashing. By reusing threads for multiple tasks, the thread-creation overhead is spread over many tasks. As a bonus, because the thread already exists when a request arrives, the delay introduced by thread creation is eliminated. Thus, the request can be serviced immediately. Furthermore, by properly tuning the number of threads in the thread pool, resource thrashing may also be eliminated by forcing any request to wait until a thread is available to process it.

thread(n) 2.8 "Tcl Threading"

Name

thread - Extension for script access to Tcl threading

Description

The thread extension creates threads that contain Tcl interpreters, and it lets you send scripts to those threads for evaluation. Additionaly, it provides script-level access to basic thread synchronization primitives, like mutexes and condition variables.

COMMANDS

This section describes commands for creating and destroying threads and sending scripts to threads for evaluation.

thread::create ?-joinable? ?-preserved? ?script?

This command creates a thread that contains a Tcl interpreter. The Tcl interpreter either evaluates the optional script, if specified, or it waits in the event loop for scripts that arrive via the thread::send command. The result, if any, of the optional script is never returned to the caller. The result of thread::create is the ID of the thread. This is the opaque handle which identifies the newly created thread for all other package commands. The handle of the thread goes out of scope automatically when thread is marked for exit (see the thread::release command below).

If the optional script argument contains the thread::wait command the thread will enter into the event loop. If such command is not found in the script the thread will run the script to the end and exit. In that case, the handle may be safely ignored since it refers to a thread which does not exists any more at the time when the command returns.

Using flag -joinable it is possible to create a joinable thread, i.e. one upon whose exit can be waited upon by using thread::join command. Note that failure to join a thread created with -joinable flag results in resource and memory leaks.

Threads created by the thread::create cannot be destroyed forcefully. Consequently, there is no corresponding thread destroy command. A thread may only be released using the thread::release and if its internal reference count drops to zero, the thread is marked for exit. This kicks the thread out of the event loop servicing and the thread continues to execute commands passed in the script argument, following the thread::wait command. If this was the last command in the script, as usualy the case, the thread will exit.

It is possible to create a situation in which it may be impossible to terminate the thread, for example by putting some endless loop after the thread::wait or entering the event loop again by doing an vwait-type of command. In such cases, the thread may never exit. This is considered to be a bad practice and should be avoided if possible. This is best illustrated by the example below:

    # You should never do ...
    set tid [thread::create {
        package require Http
        thread::wait
        vwait forever ; # <-- this!
    }]

The thread created in the above example will never be able to exit. After it has been released with the last matching thread::release call, the thread will jump out of the thread::wait and continue to execute commands following. It will enter vwait command and wait endlessly for events. There is no way one can terminate such thread, so you wouldn't want to do this!

Each newly created has its internal reference counter set to 0 (zero), i.e. it is unreserved. This counter gets incremented by a call to thread::preserve and decremented by a call to thread::release command. These two commands implement simple but effective thread reservation system and offer predictable and controllable thread termination capabilities. It is however possible to create initialy preserved threads by using flag -preserved of the thread::create command. Threads created with this flag have the initial value of the reference counter of 1 (one), and are thus initially marked reserved.

thread::preserve ?id?

This command increments the thread reference counter. Each call to this command increments the reference counter by one (1). Command returns the value of the reference counter after the increment. If called with the optional thread id, the command preserves the given thread. Otherwise the current thread is preserved.

With reference counting, one can implement controlled access to a shared Tcl thread. By incrementing the reference counter, the caller signalizes that he/she wishes to use the thread for a longer period of time. By decrementing the counter, caller signalizes that he/she has finished using the thread.

thread::release ?-wait? ?id?

This command decrements the thread reference counter. Each call to this command decrements the reference counter by one (1). If called with the optional thread id, the command releases the given thread. Otherwise, the current thread is released. Command returns the value of the reference counter after the decrement. When the reference counter reaches zero (0), the target thread is marked for termination. You should not reference the thread after the thread::release command returns zero or negative integer. The handle of the thread goes out of scope and should not be used any more. Any following reference to the same thread handle will result in Tcl error.

Optional flag -wait instructs the caller thread to wait for the target thread to exit, if the effect of the command would result in termination of the target thread, i.e. if the return result would be zero (0). Without the flag, the caller thread does not wait for the target thread to exit. Care must be taken when using the -wait, since this may block the caller thread indefinitely. This option has been implemented for some special uses of the extension and is deprecated for regular use. Regular users should create joinable threads by using the -joinable option of the thread::create command and the thread::join to wait for thread to exit.

thread::id

This command returns the ID of the current thread.

thread::errorproc ?procname?

This command sets a handler for errors that occur in scripts sent asynchronously, using the -async flag of the thread::send command, to other threads. If no handler is specified, the current handler is returned. The empty string resets the handler to default (unspecified) value. An uncaught error in a thread causes an error message to be sent to the standard error channel. This default reporting scheme can be changed by registering a procedure which is called to report the error. The procname is called in the interpreter that invoked the thread::errorproc command. The procname is called like this:

    myerrorproc thread_id errorInfo
thread::cancel ?-unwind? id ?result?

This command requires Tcl version 8.6 or higher.

Cancels the script being evaluated in the thread given by the id parameter. Without the -unwind switch the evaluation stack for the interpreter is unwound until an enclosing catch command is found or there are no further invocations of the interpreter left on the call stack. With the -unwind switch the evaluation stack for the interpreter is unwound without regard to any intervening catch command until there are no further invocations of the interpreter left on the call stack. If result is present, it will be used as the error message string; otherwise, a default error message string will be used.

thread::unwind

Use of this command is deprecated in favour of more advanced thread reservation system implemented with thread::preserve and thread::release commands. Support for thread::unwind command will dissapear in some future major release of the extension.

This command stops a prior thread::wait command. Execution of the script passed to newly created thread will continue from the thread::wait command. If thread::wait was the last command in the script, the thread will exit. The command returns empty result but may trigger Tcl error with the message "target thread died" in some situations.

thread::exit ?status?

Use of this command is deprecated in favour of more advanced thread reservation system implemented with thread::preserve and thread::release commands. Support for thread::exit command will dissapear in some future major release of the extension.

This command forces a thread stuck in the thread::wait command to unconditionaly exit. The thread's exit status defaults to 666 and can be specified using the optional status argument. The execution of thread::exit command is guaranteed to leave the program memory in the unconsistent state, produce memory leaks and otherwise affect other subsytem(s) of the Tcl application in an unpredictable manner. The command returns empty result but may trigger Tcl error with the message "target thread died" in some situations.

thread::names

This command returns a list of thread IDs. These are only for threads that have been created via thread::create command. If your application creates other threads at the C level, they are not reported by this command.

thread::exists id

Returns true (1) if thread given by the id parameter exists, false (0) otherwise. This applies only for threads that have been created via thread::create command.

thread::send ?-async? ?-head? id script ?varname?

This command passes a script to another thread and, optionally, waits for the result. If the -async flag is specified, the command does not wait for the result and it returns empty string. The target thread must enter it's event loop in order to receive scripts sent via this command. This is done by default for threads created without a startup script. Threads can enter the event loop explicitly by calling thread::wait or any other relevant Tcl/Tk command, like update, vwait, etc.

Optional varname specifies name of the variable to store the result of the script. Without the -async flag, the command returns the evaluation code, similarily to the standard Tcl catch command. If, however, the -async flag is specified, the command returns immediately and caller can later vwait on ?varname? to get the result of the passed script

    set t1 [thread::create]
    set t2 [thread::create]
    thread::send -async $t1 "set a 1" result
    thread::send -async $t2 "set b 2" result
    for {set i 0} {$i < 2} {incr i} {
        vwait result
    }

In the above example, two threads were fed work and both of them were instructed to signalize the same variable "result" in the calling thread. The caller entered the event loop twice to get both results. Note, however, that the order of the received results may vary, depending on the current system load, type of work done, etc, etc.

Many threads can simultaneously send scripts to the target thread for execution. All of them are entered into the event queue of the target thread and executed on the FIFO basis, intermingled with optional other events pending in the event queue of the target thread. Using the optional ?-head? switch, scripts posted to the thread's event queue can be placed on the head, instead on the tail of the queue, thus being executed in the LIFO fashion.

thread::broadcast script

This command passes a script to all threads created by the package for execution. It does not wait for response from any of the threads.

thread::wait

This enters the event loop so a thread can receive messages from the thread::send command. This command should only be used within the script passed to the thread::create. It should be the very last command in the script. If this is not the case, the exiting thread will continue executing the script lines past the thread::wait which is usually not what you want and/or expect.

    set t1 [thread::create {
        #
        # Do some initialization work here
        #
        thread::wait ; # Enter the event loop
    }]
thread::eval ?-lock mutex? arg ?arg ...?

This command concatenates passed arguments and evaluates the resulting script under the mutex protection. If no mutex is specified by using the ?-lock mutex? optional argument, the internal static mutex is used.

thread::join id

This command waits for the thread with ID id to exit and then returns it's exit code. Errors will be returned for threads which are not joinable or already waited upon by another thread. Upon the join the handle of the thread has gone out of scope and should not be used any more.

thread::configure id ?option? ?value? ?...?

This command configures various low-level aspects of the thread with ID id in the similar way as the standard Tcl command fconfigure configures some Tcl channel options. Options currently supported are: -eventmark and -unwindonerror.

The -eventmark option, when set, limits the number of asynchronously posted scripts to the thread event loop. The thread::send -async command will block until the number of pending scripts in the event loop does not drop below the value configured with -eventmark. Default value for the -eventmark is 0 (zero) which effectively disables the checking, i.e. allows for unlimited number of posted scripts.

The -unwindonerror option, when set, causes the target thread to unwind if the result of the script processing resulted in error. Default value for the -unwindonerror is 0 (false), i.e. thread continues to process scripts after one of the posted scripts fails.

thread::transfer id channel

This moves the specified channel from the current thread and interpreter to the main interpreter of the thread with the given id. After the move the current interpreter has no access to the channel any more, but the main interpreter of the target thread will be able to use it from now on. The command waits until the other thread has incorporated the channel. Because of this it is possible to deadlock the participating threads by commanding the other through a synchronous thread::send to transfer a channel to us. This easily extends into longer loops of threads waiting for each other. Other restrictions: the channel in question must not be shared among multiple interpreters running in the sending thread. This automatically excludes the special channels for standard input, output and error.

Due to the internal Tcl core implementation and the restriction on transferring shared channels, one has to take extra measures when transferring socket channels created by accepting the connection out of the socket commands callback procedures:

    socket -server _Accept 2200
    proc _Accept {s ipaddr port} {
        after idle [list Accept $s $ipaddr $port]
    }
    proc Accept {s ipaddr port} {
        set tid [thread::create]
        thread::transfer $tid $s
    }
thread::detach channel

This detaches the specified channel from the current thread and interpreter. After that, the current interpreter has no access to the channel any more. The channel is in the parked state until some other (or the same) thread attaches the channel again with thread::attach. Restrictions: same as for transferring shared channels with the thread::transfer command.

thread::attach channel

This attaches the previously detached channel in the current thread/interpreter. For already existing channels, the command does nothing, i.e. it is not an error to attach the same channel more than once. The first operation will actualy perform the operation, while all subsequent operation will just do nothing. Command throws error if the channel cannot be found in the list of detached channels and/or in the current interpreter.

thread::mutex

Mutexes are most common thread synchronization primitives. They are used to synchronize access from two or more threads to one or more shared resources. This command provides script-level access to exclusive and/or recursive mutexes. Exclusive mutexes can be locked only once by one thread, while recursive mutexes can be locked many times by the same thread. For recursive mutexes, number of lock and unlock operations must match, otherwise, the mutex will never be released, which would lead to various deadlock situations.

Care has to be taken when using mutexes in an multithreading program. Improper use of mutexes may lead to various deadlock situations, especially when using exclusive mutexes.

The thread::mutex command supports following subcommands and options:

thread::mutex create ?-recursive?

Creates the mutex and returns it's opaque handle. This handle should be used for any future reference to the newly created mutex. If no optional ?-recursive? argument was specified, the command creates the exclusive mutex. With the ?-recursive? argument, the command creates a recursive mutex.

thread::mutex destroy mutex

Destroys the mutex. Mutex should be in unlocked state before the destroy attempt. If the mutex is locked, the command will throw Tcl error.

thread::mutex lock mutex

Locks the mutex. Locking the exclusive mutex may throw Tcl error if on attempt to lock the same mutex twice from the same thread. If your program logic forces you to lock the same mutex twice or more from the same thread (this may happen in recursive procedure invocations) you should consider using the recursive mutexes.

thread::mutex unlock mutex

Unlocks the mutex so some other thread may lock it again. Attempt to unlock the already unlocked mutex will throw Tcl error.

thread::rwmutex

This command creates many-readers/single-writer mutexes. Reader/writer mutexes allow you to serialize access to a shared resource more optimally. In situations where a shared resource gets mostly read and seldom modified, you might gain some performace by using reader/writer mutexes instead of exclusive or recursive mutexes.

For reading the resource, thread should obtain a read lock on the resource. Read lock is non-exclusive, meaning that more than one thread can obtain a read lock to the same resource, without waiting on other readers. For changing the resource, however, a thread must obtain a exclusive write lock. This lock effectively blocks all threads from gaining the read-lock while the resource is been modified by the writer thread. Only after the write lock has been released, the resource may be read-locked again.

The thread::rwmutex command supports following subcommands and options:

thread::rwmutex create

Creates the reader/writer mutex and returns it's opaque handle. This handle should be used for any future reference to the newly created mutex.

thread::rwmutex destroy mutex

Destroys the reader/writer mutex. If the mutex is already locked, attempt to destroy it will throw Tcl error.

thread::rwmutex rlock mutex

Locks the mutex for reading. More than one thread may read-lock the same mutex at the same time.

thread::rwmutex wlock mutex

Locks the mutex for writing. Only one thread may write-lock the same mutex at the same time. Attempt to write-lock same mutex twice from the same thread will throw Tcl error.

thread::rwmutex unlock mutex

Unlocks the mutex so some other thread may lock it again. Attempt to unlock already unlocked mutex will throw Tcl error.

thread::cond

This command provides script-level access to condition variables. A condition variable creates a safe environment for the program to test some condition, sleep on it when false and be awakened when it might have become true. A condition variable is always used in the conjuction with an exclusive mutex. If you attempt to use other type of mutex in conjuction with the condition variable, a Tcl error will be thrown.

The command supports following subcommands and options:

thread::cond create

Creates the condition variable and returns it's opaque handle. This handle should be used for any future reference to newly created condition variable.

thread::cond destroy cond

Destroys condition variable cond. Extreme care has to be taken that nobody is using (i.e. waiting on) the condition variable, otherwise unexpected errors may happen.

thread::cond notify cond

Wakes up all threads waiting on the condition variable cond.

thread::cond wait cond mutex ?ms?

This command is used to suspend program execution until the condition variable cond has been signalled or the optional timer has expired. The exclusive mutex must be locked by the calling thread on entrance to this command. If the mutex is not locked, Tcl error is thrown. While waiting on the cond, the command releases mutex. Before returning to the calling thread, the command re-acquires the mutex again. Unlocking the mutex and waiting on the condition variable cond is done atomically.

The ms command option, if given, must be an integer specifying time interval in milliseconds the command waits to be signalled. Otherwise the command waits on condition notify forever.

In multithreading programs, there are many situations where a thread has to wait for some event to happen until it is allowed to proceed. This is usually accomplished by repeatedly testing a condition under the mutex protection and waiting on the condition variable until the condition evaluates to true:

    set mutex [thread::mutex create]
    set cond  [thread::cond  create]
    thread::mutex lock $mutex
    while {<some_condition_is_true>} {
        thread::cond wait $cond $mutex
    }
    # Do some work under mutex protection
    thread::mutex unlock $mutex

Repeated testing of the condition is needed since the condition variable may get signalled without the condition being actually changed (spurious thread wake-ups, for example).

DISCUSSION

The fundamental threading model in Tcl is that there can be one or more Tcl interpreters per thread, but each Tcl interpreter should only be used by a single thread which created it. A "shared memory" abstraction is awkward to provide in Tcl because Tcl makes assumptions about variable and data ownership. Therefore this extension supports a simple form of threading where the main thread can manage several background, or "worker" threads. For example, an event-driven server can pass requests to worker threads, and then await responses from worker threads or new client requests. Everything goes through the common Tcl event loop, so message passing between threads works naturally with event-driven I/O, vwait on variables, and so forth. For the transfer of bulk information it is possible to move channels between the threads.

For advanced multithreading scripts, script-level access to two basic synchronization primitives, mutex and condition variables, is also supported.

ttrace(n) 2.8 "Tcl Threading"

Name

ttrace - Trace-based interpreter initialization

Description

This package creates a framework for on-demand replication of the interpreter state accross threads in an multithreading application. It relies on the mechanics of Tcl command tracing and the Tcl unknown command and mechanism.

The package requires Tcl threading extension but can be alternatively used stand-alone within the AOLserver, a scalable webserver from America Online.

In a nutshell, a short sample illustrating the usage of the ttrace with the Tcl threading extension:

    % package require Ttrace
    2.8.0
    % set t1 [thread::create {package require Ttrace; thread::wait}]
    tid0x1802800
    % ttrace::eval {proc test args {return test-[thread::id]}}
    % thread::send $t1 test
    test-tid0x1802800
    % set t2 [thread::create {package require Ttrace; thread::wait}]
    tid0x1804000
    % thread::send $t2 test
    test-tid0x1804000

As seen from above, the ttrace::eval and ttrace::update commands are used to create a thread-wide definition of a simple Tcl procedure and replicate that definition to all, already existing or later created, threads.

USER COMMANDS

This section describes user-level commands. Those commands can be used by script writers to control the execution of the tracing framework.

ttrace::eval arg ?arg ...?

This command concatenates given arguments and evaluates the resulting Tcl command with trace framework enabled. If the command execution was ok, it takes necessary steps to automatically propagate the trace epoch change to all threads in the application. For AOLserver, only newly created threads actually receive the epoch change. For the Tcl threading extension, all threads created by the extension are automatically updated. If the command execution resulted in Tcl error, no state propagation takes place.

This is the most important user-level command of the package as it wraps most of the commands described below. This greatly simplifies things, because user need to learn just this (one) command in order to effectively use the package. Other commands, as desribed below, are included mostly for the sake of completeness.

ttrace::enable

Activates all registered callbacks in the framework and starts a new trace epoch. The trace epoch encapsulates all changes done to the interpreter during the time traces are activated.

ttrace::disable

Deactivates all registered callbacks in the framework and closes the current trace epoch.

ttrace::cleanup

Used to clean-up all on-demand loaded resources in the interpreter. It effectively brings Tcl interpreter to its pristine state.

ttrace::update ?epoch?

Used to refresh the state of the interpreter to match the optional trace ?epoch?. If the optional ?epoch? is not given, it takes the most recent trace epoch.

ttrace::getscript

Returns a synthetized Tcl script which may be sourced in any interpreter. This script sets the stage for the Tcl unknown command so it can load traced resources from the in-memory database. Normally, this command is automatically invoked by other higher-level commands like ttrace::eval and ttrace::update.

CALLBACK COMMANDS

A word upfront: the package already includes callbacks for tracing following Tcl commands: proc, namespace, variable, load, and rename. Additionaly, a set of callbacks for tracing resources (object, clasess) for the XOTcl v1.3.8+, an OO-extension to Tcl, is also provided. This gives a solid base for solving most of the real-life needs and serves as an example for people wanting to customize the package to cover their specific needs.

Below, you can find commands for registering callbacks in the framework and for writing callback scripts. These callbacks are invoked by the framework in order to gather interpreter state changes, build in-memory database, perform custom-cleanups and various other tasks.

ttrace::atenable cmd arglist body

Registers Tcl callback to be activated at ttrace::enable. Registered callbacks are activated on FIFO basis. The callback definition includes the name of the callback, cmd, a list of callback arguments, arglist and the body of the callback. Effectively, this actually resembles the call interface of the standard Tcl proc command.

ttrace::atdisable cmd arglist body

Registers Tcl callback to be activated at ttrace::disable. Registered callbacks are activated on FIFO basis. The callback definition includes the name of the callback, cmd, a list of callback arguments, arglist and the body of the callback. Effectively, this actually resembles the call interface of the standard Tcl proc command.

ttrace::addtrace cmd arglist body

Registers Tcl callback to be activated for tracing the Tcl cmd command. The callback definition includes the name of the Tcl command to trace, cmd, a list of callback arguments, arglist and the body of the callback. Effectively, this actually resembles the call interface of the standard Tcl proc command.

ttrace::addscript name body

Registers Tcl callback to be activated for building a Tcl script to be passed to other interpreters. This script is used to set the stage for the Tcl unknown command. Registered callbacks are activated on FIFO basis. The callback definition includes the name of the callback, name and the body of the callback.

ttrace::addresolver cmd arglist body

Registers Tcl callback to be activated by the overloaded Tcl unknown command. Registered callbacks are activated on FIFO basis. This callback is used to resolve the resource and load the resource in the current interpreter.

ttrace::addcleanup body

Registers Tcl callback to be activated by the trace::cleanup. Registered callbacks are activated on FIFO basis.

ttrace::addentry cmd var val

Adds one entry to the named in-memory database.

ttrace::getentry cmd var

Returns the value of the entry from the named in-memory database.

ttrace::getentries cmd ?pattern?

Returns names of all entries from the named in-memory database.

ttrace::delentry cmd

Deletes an entry from the named in-memory database.

ttrace::preload cmd

Registers the Tcl command to be loaded in the interpreter. Commands registered this way will always be the part of the interpreter and not be on-demand loaded by the Tcl unknown command.

DISCUSSION

Common introspective state-replication approaches use a custom Tcl script to introspect the running interpreter and synthesize another Tcl script to replicate this state in some other interpreter. This package, on the contrary, uses Tcl command traces. Command traces are registered on selected Tcl commands, like proc, namespace, load and other standard (and/or user-defined) Tcl commands. When activated, those traces build an in-memory database of created resources. This database is used as a resource repository for the (overloaded) Tcl unknown command which creates the requested resource in the interpreter on demand. This way, users can update just one interpreter (master) in one thread and replicate that interpreter state (or part of it) to other threads/interpreters in the process.

Immediate benefit of such approach is the much smaller memory footprint of the application and much faster thread creation. By not actually loading all necessary procedures (and other resources) in every thread at the thread initialization time, but by deffering this to the time the resource is actually referenced, significant improvements in both memory consumption and thread initialization time can be achieved. Some tests have shown that memory footprint of an multithreading Tcl application went down more than three times and thread startup time was reduced for about 50 times. Note that your mileage may vary. Other benefits include much finer control about what (and when) gets replicated from the master to other Tcl thread/interpreters.

tsv(n) 2.8 "Tcl Threading"

Name

tsv - Part of the Tcl threading extension allowing script level manipulation of data shared between threads.

Description

This section describes commands implementing thread shared variables. A thread shared variable is very similar to a Tcl array but in contrast to a Tcl array it is created in shared memory and can be accessed from many threads at the same time. Important feature of thread shared variable is that each access to the variable is internaly protected by a mutex so script programmer does not have to take care about locking the variable himself.

Thread shared variables are not bound to any thread explicitly. That means that when a thread which created any of thread shared variables exits, the variable and associated memory is not unset/reclaimed. User has to explicitly unset the variable to reclaim the memory consumed by the variable.

ELEMENT COMMANDS

tsv::names ?pattern?

Returns names of shared variables matching optional ?pattern? or all known variables if pattern is ommited.

tsv::object varname element

Creates object accessor command for the element in the shared variable varname. Using this command, one can apply most of the other shared variable commands as method functions of the element object command. The object command is automatically deleted when the element which this command is pointing to is unset.

    % tsv::set foo bar "A shared string"
    % set string [tsv::object foo bar]
    % $string append " appended"
    => A shared string appended
tsv::set varname element ?value?

Sets the value of the element in the shared variable varname to value and returns the value to caller. The value may be ommited, in which case the command will return the current value of the element. If the element cannot be found, error is triggered.

tsv::get varname element ?namedvar?

Retrieves the value of the element from the shared variable varname. If the optional argument namedvar is given, the value is stored in the named variable. Return value of the command depends of the existence of the optional argument namedvar. If the argument is ommited and the requested element cannot be found in the shared array, the command triggers error. If, however, the optional argument is given on the command line, the command returns true (1) if the element is found or false (0) if the element is not found.

tsv::unset varname ?element?

Unsets the element from the shared variable varname. If the optional element is not given, it deletes the variable.

tsv::exists varname element

Checks wether the element exists in the shared variable varname and returns true (1) if it does or false (0) if it doesn't.

tsv::pop varname element

Returns value of the element in the shared variable varname and unsets the element, all in one atomic operation.

tsv::move varname oldname newname

Renames the element oldname to the newname in the shared variable varname. This effectively performs an get/unset/set sequence of operations but all in one atomic step.

tsv::incr varname element ?count?

Similar to standard Tcl incr command but increments the value of the element in shared variaboe varname instead of the Tcl variable.

tsv::append varname element value ?value ...?

Similar to standard Tcl append command but appends one or more values to the element in shared variable varname instead of the Tcl variable.

tsv::lock varname arg ?arg ...?

This command concatenates passed arguments and evaluates the resulting script under the internal mutex protection. During the script evaluation, the entire shared variable is locked. For shared variable commands within the script, internal locking is disabled so no deadlock can occur. It is also allowed to unset the shared variable from within the script. The shared variable is automatically created if it did not exists at the time of the first lock operation.

    % tsv::lock foo {
        tsv::lappend foo bar 1
        tsv::lappend foo bar 2
        puts stderr [tsv::set foo bar]
        tsv::unset foo
    }
tsv::handlers

Returns the names of all persistent storage handlers enabled at compile time. See ARRAY COMMANDS for details.

LIST COMMANDS

Those command are similar to the equivalently named Tcl command. The difference is that they operate on elements of shared arrays.

tsv::lappend varname element value ?value ...?

Similar to standard Tcl lappend command but appends one or more values to the element in shared variable varname instead of the Tcl variable.

tsv::linsert varname element index value ?value ...?

Similar to standard Tcl linsert command but inserts one or more values at the index list position in the element in the shared variable varname instead of the Tcl variable.

tsv::lreplace varname element first last ?value ...?

Similar to standard Tcl lreplace command but replaces one or more values between the first and last position in the element of the shared variable varname instead of the Tcl variable.

tsv::llength varname element

Similar to standard Tcl llength command but returns length of the element in the shared variable varname instead of the Tcl variable.

tsv::lindex varname element ?index?

Similar to standard Tcl lindex command but returns the value at the index list position of the element from the shared variable varname instead of the Tcl variable.

tsv::lrange varname element from to

Similar to standard Tcl lrange command but returns values between from and to list positions from the element in the shared variable varname instead of the Tcl variable.

tsv::lsearch varname element ?options? pattern

Similar to standard Tcl lsearch command but searches the element in the shared variable varname instead of the Tcl variable.

tsv::lset varname element index ?index ...? value

Similar to standard Tcl lset command but sets the element in the shared variable varname instead of the Tcl variable.

tsv::lpop varname element ?index?

Similar to the standard Tcl lindex command but in addition to returning, it also splices the value out of the element from the shared variable varname in one atomic operation. In contrast to the Tcl lindex command, this command returns no value to the caller.

tsv::lpush varname element ?index?

This command performes the opposite of the tsv::lpop command. As its counterpart, it returns no value to the caller.

ARRAY COMMANDS

This command supports most of the options of the standard Tcl array command. In addition to those, it allows binding a shared variable to some persisten storage databases. Currently the persistent options supported are the famous GNU Gdbm and LMDB. These options have to be selected during the package compilation time. The implementation provides hooks for defining other persistency layers, if needed.

tsv::array set varname list

Does the same as standard Tcl array set.

tsv::array get varname ?pattern?

Does the same as standard Tcl array get.

tsv::array names varname ?pattern?

Does the same as standard Tcl array names.

tsv::array size varname

Does the same as standard Tcl array size.

tsv::array reset varname list

Does the same as standard Tcl array set but it clears the varname and sets new values from the list atomically.

tsv::array bind varname handle

Binds the varname to the persistent storage handle. The format of the handle is <handler>:<address>, where <handler> is "gdbm" for GNU Gdbm and "lmdb" for LMDB and <address> is the path to the database file.

tsv::array unbind varname

Unbinds the shared array from its bound persistent storage.

tsv::array isbound varname

Returns true (1) if the shared varname is bound to some persistent storage or zero (0) if not.

KEYED LIST COMMANDS

Keyed list commands are borrowed from the TclX package. Keyed lists provide a structured data type built upon standard Tcl lists. This is a functionality similar to structs in the C programming language.

A keyed list is a list in which each element contains a key and value pair. These element pairs are stored as lists themselves, where the key is the first element of the list, and the value is the second. The key-value pairs are referred to as fields. This is an example of a keyed list:

    {{NAME  {Frank  Zappa}} {JOB {musician and composer}}}

Fields may contain subfields; `.' is the separator character. Subfields are actually fields where the value is another keyed list. Thus the following list has the top level fields ID and NAME, and subfields NAME.FIRST and NAME.LAST:

    {ID 106} {NAME {{FIRST Frank} {LAST Zappa}}}

There is no limit to the recursive depth of subfields, allowing one to build complex data structures. Keyed lists are constructed and accessed via a number of commands. All keyed list management commands take the name of the variable containing the keyed list as an argument (i.e. passed by reference), rather than passing the list directly.

tsv::keyldel varname keylist key

Delete the field specified by key from the keyed list keylist in the shared variable varname. This removes both the key and the value from the keyed list.

tsv::keylget varname keylist key ?retvar?

Return the value associated with key from the keyed list keylist in the shared variable varname. If the optional retvar is not specified, then the value will be returned as the result of the command. In this case, if key is not found in the list, an error will result.

If retvar is specified and key is in the list, then the value is returned in the variable retvar and the command returns 1 if the key was present within the list. If key isn't in the list, the command will return 0, and retvar will be left unchanged. If {} is specified for retvar, the value is not returned, allowing the Tcl programmer to determine if a key is present in a keyed list without setting a variable as a side-effect.

tsv::keylkeys varname keylist ?key?

Return the a list of the keys in the keyed list keylist in the shared variable varname. If key is specified, then it is the name of a key field who's subfield keys are to be retrieved.

tsv::keylset varname keylist key value ?key value..?

Set the value associated with key, in the keyed list keylist to value. If the keylist does not exists, it is created. If key is not currently in the list, it will be added. If it already exists, value replaces the existing value. Multiple keywords and values may be specified, if desired.

DISCUSSION

The current implementation of thread shared variables allows for easy and convenient access to data shared between different threads. Internally, the data is stored in Tcl objects and all package commands operate on internal data representation, thus minimizing shimmering and improving performance. Special care has been taken to assure that all object data is properly locked and deep-copied when moving objects between threads.

Due to the internal design of the Tcl core, there is no provision of full integration of shared variables within the Tcl syntax, unfortunately. All access to shared data must be performed with the supplied package commands. Also, variable traces are not supported. But even so, benefits of easy, simple and safe shared data manipulation outweights imposed limitations.

CREDITS

Thread shared variables are inspired by the nsv interface found in AOLserver, a highly scalable Web server from America Online.

It relies on the mechanics of Tcl command tracing and the Tcl \fBunknown\fR command and mechanism\&. .PP The package requires Tcl threading extension but can be alternatively used stand-alone within the AOLserver, a scalable webserver from America Online\&. .PP In a nutshell, a short sample illustrating the usage of the ttrace with the Tcl threading extension: .CS % package require Ttrace 2\&.8\&.0 % set t1 [thread::create {package require Ttrace; thread::wait}] tid0x1802800 % ttrace::eval {proc test args {return test-[thread::id]}} % thread::send $t1 test test-tid0x1802800 % set t2 [thread::create {package require Ttrace; thread::wait}] tid0x1804000 % thread::send $t2 test test-tid0x1804000 .CE .PP As seen from above, the \fBttrace::eval\fR and \fBttrace::update\fR commands are used to create a thread-wide definition of a simple Tcl procedure and replicate that definition to all, already existing or later created, threads\&. .SH "USER COMMANDS" This section describes user-level commands\&. Those commands can be used by script writers to control the execution of the tracing framework\&. .TP \fBttrace::eval\fR \fIarg\fR ?arg \&.\&.\&.? This command concatenates given arguments and evaluates the resulting Tcl command with trace framework enabled\&. If the command execution was ok, it takes necessary steps to automatically propagate the trace epoch change to all threads in the application\&. For AOLserver, only newly created threads actually receive the epoch change\&. For the Tcl threading extension, all threads created by the extension are automatically updated\&. If the command execution resulted in Tcl error, no state propagation takes place\&. .sp This is the most important user-level command of the package as it wraps most of the commands described below\&. This greatly simplifies things, because user need to learn just this (one) command in order to effectively use the package\&. Other commands, as desribed below, are included mostly for the sake of completeness\&. .TP \fBttrace::enable\fR Activates all registered callbacks in the framework and starts a new trace epoch\&. The trace epoch encapsulates all changes done to the interpreter during the time traces are activated\&. .TP \fBttrace::disable\fR Deactivates all registered callbacks in the framework and closes the current trace epoch\&. .TP \fBttrace::cleanup\fR Used to clean-up all on-demand loaded resources in the interpreter\&. It effectively brings Tcl interpreter to its pristine state\&. .TP \fBttrace::update\fR ?epoch? Used to refresh the state of the interpreter to match the optional trace ?epoch?\&. If the optional ?epoch? is not given, it takes the most recent trace epoch\&. .TP \fBttrace::getscript\fR Returns a synthetized Tcl script which may be sourced in any interpreter\&. This script sets the stage for the Tcl \fBunknown\fR command so it can load traced resources from the in-memory database\&. Normally, this command is automatically invoked by other higher-level commands like \fBttrace::eval\fR and \fBttrace::update\fR\&. .PP .SH "CALLBACK COMMANDS" A word upfront: the package already includes callbacks for tracing following Tcl commands: \fBproc\fR, \fBnamespace\fR, \fBvariable\fR, \fBload\fR, and \fBrename\fR\&. Additionaly, a set of callbacks for tracing resources (object, clasess) for the XOTcl v1\&.3\&.8+, an OO-extension to Tcl, is also provided\&. This gives a solid base for solving most of the real-life needs and serves as an example for people wanting to customize the package to cover their specific needs\&. .PP Below, you can find commands for registering callbacks in the framework and for writing callback scripts\&. These callbacks are invoked by the framework in order to gather interpreter state changes, build in-memory database, perform custom-cleanups and various other tasks\&. .TP \fBttrace::atenable\fR \fIcmd\fR \fIarglist\fR \fIbody\fR Registers Tcl callback to be activated at \fBttrace::enable\fR\&. Registered callbacks are activated on FIFO basis\&. The callback definition includes the name of the callback, \fIcmd\fR, a list of callback arguments, \fIarglist\fR and the \fIbody\fR of the callback\&. Effectively, this actually resembles the call interface of the standard Tcl \fBproc\fR command\&. .TP \fBttrace::atdisable\fR \fIcmd\fR \fIarglist\fR \fIbody\fR Registers Tcl callback to be activated at \fBttrace::disable\fR\&. Registered callbacks are activated on FIFO basis\&. The callback definition includes the name of the callback, \fIcmd\fR, a list of callback arguments, \fIarglist\fR and the \fIbody\fR of the callback\&. Effectively, this actually resembles the call interface of the standard Tcl \fBproc\fR command\&. .TP \fBttrace::addtrace\fR \fIcmd\fR \fIarglist\fR \fIbody\fR Registers Tcl callback to be activated for tracing the Tcl \fBcmd\fR command\&. The callback definition includes the name of the Tcl command to trace, \fIcmd\fR, a list of callback arguments, \fIarglist\fR and the \fIbody\fR of the callback\&. Effectively, this actually resembles the call interface of the standard Tcl \fBproc\fR command\&. .TP \fBttrace::addscript\fR \fIname\fR \fIbody\fR Registers Tcl callback to be activated for building a Tcl script to be passed to other interpreters\&. This script is used to set the stage for the Tcl \fBunknown\fR command\&. Registered callbacks are activated on FIFO basis\&. The callback definition includes the name of the callback, \fIname\fR and the \fIbody\fR of the callback\&. .TP \fBttrace::addresolver\fR \fIcmd\fR \fIarglist\fR \fIbody\fR Registers Tcl callback to be activated by the overloaded Tcl \fBunknown\fR command\&. Registered callbacks are activated on FIFO basis\&. This callback is used to resolve the resource and load the resource in the current interpreter\&. .TP \fBttrace::addcleanup\fR \fIbody\fR Registers Tcl callback to be activated by the \fBtrace::cleanup\fR\&. Registered callbacks are activated on FIFO basis\&. .TP \fBttrace::addentry\fR \fIcmd\fR \fIvar\fR \fIval\fR Adds one entry to the named in-memory database\&. .TP \fBttrace::getentry\fR \fIcmd\fR \fIvar\fR Returns the value of the entry from the named in-memory database\&. .TP \fBttrace::getentries\fR \fIcmd\fR ?pattern? Returns names of all entries from the named in-memory database\&. .TP \fBttrace::delentry\fR \fIcmd\fR Deletes an entry from the named in-memory database\&. .TP \fBttrace::preload\fR \fIcmd\fR Registers the Tcl command to be loaded in the interpreter\&. Commands registered this way will always be the part of the interpreter and not be on-demand loaded by the Tcl \fBunknown\fR command\&. .PP .SH DISCUSSION Common introspective state-replication approaches use a custom Tcl script to introspect the running interpreter and synthesize another Tcl script to replicate this state in some other interpreter\&. This package, on the contrary, uses Tcl command traces\&. Command traces are registered on selected Tcl commands, like \fBproc\fR, \fBnamespace\fR, \fBload\fR and other standard (and/or user-defined) Tcl commands\&. When activated, those traces build an in-memory database of created resources\&. This database is used as a resource repository for the (overloaded) Tcl \fBunknown\fR command which creates the requested resource in the interpreter on demand\&. This way, users can update just one interpreter (master) in one thread and replicate that interpreter state (or part of it) to other threads/interpreters in the process\&. .PP Immediate benefit of such approach is the much smaller memory footprint of the application and much faster thread creation\&. By not actually loading all necessary procedures (and other resources) in every thread at the thread initialization time, but by deffering this to the time the resource is actually referenced, significant improvements in both memory consumption and thread initialization time can be achieved\&. Some tests have shown that memory footprint of an multithreading Tcl application went down more than three times and thread startup time was reduced for about 50 times\&. Note that your mileage may vary\&. Other benefits include much finer control about what (and when) gets replicated from the master to other Tcl thread/interpreters\&. .SH "SEE ALSO" thread, tpool, tsv .SH KEYWORDS command tracing, introspection thread2.8.0/doc/man/tsv.n0000644003604700454610000005105412726254163013636 0ustar dgp771div'\" '\" Generated from file '' by tcllib/doctools with format 'nroff' '\" .TH "tsv" n 2\&.8 "Tcl Threading" .\" The -*- nroff -*- definitions below are for supplemental macros used .\" in Tcl/Tk manual entries. .\" .\" .AP type name in/out ?indent? .\" Start paragraph describing an argument to a library procedure. .\" type is type of argument (int, etc.), in/out is either "in", "out", .\" or "in/out" to describe whether procedure reads or modifies arg, .\" and indent is equivalent to second arg of .IP (shouldn't ever be .\" needed; use .AS below instead) .\" .\" .AS ?type? ?name? .\" Give maximum sizes of arguments for setting tab stops.

A thread shared variable is very similar to a Tcl array but in contrast to a Tcl array it is created in shared memory and can be accessed from many threads at the same time\&. Important feature of thread shared variable is that each access to the variable is internaly protected by a mutex so script programmer does not have to take care about locking the variable himself\&. .PP Thread shared variables are not bound to any thread explicitly\&. That means that when a thread which created any of thread shared variables exits, the variable and associated memory is not unset/reclaimed\&. User has to explicitly unset the variable to reclaim the memory consumed by the variable\&. .SH "ELEMENT COMMANDS" .TP \fBtsv::names\fR ?pattern? Returns names of shared variables matching optional ?pattern? or all known variables if pattern is ommited\&. .TP \fBtsv::object\fR \fIvarname\fR \fIelement\fR Creates object accessor command for the \fIelement\fR in the shared variable \fIvarname\fR\&. Using this command, one can apply most of the other shared variable commands as method functions of the element object command\&. The object command is automatically deleted when the element which this command is pointing to is unset\&. .CS % tsv::set foo bar "A shared string" % set string [tsv::object foo bar] % $string append " appended" => A shared string appended .CE .TP \fBtsv::set\fR \fIvarname\fR \fIelement\fR ?value? Sets the value of the \fIelement\fR in the shared variable \fIvarname\fR to \fIvalue\fR and returns the value to caller\&. The \fIvalue\fR may be ommited, in which case the command will return the current value of the element\&. If the element cannot be found, error is triggered\&. .TP \fBtsv::get\fR \fIvarname\fR \fIelement\fR ?namedvar? Retrieves the value of the \fIelement\fR from the shared variable \fIvarname\fR\&. If the optional argument \fInamedvar\fR is given, the value is stored in the named variable\&. Return value of the command depends of the existence of the optional argument \fInamedvar\fR\&. If the argument is ommited and the requested element cannot be found in the shared array, the command triggers error\&. If, however, the optional argument is given on the command line, the command returns true (1) if the element is found or false (0) if the element is not found\&. .TP \fBtsv::unset\fR \fIvarname\fR ?element? Unsets the \fIelement\fR from the shared variable \fIvarname\fR\&. If the optional element is not given, it deletes the variable\&. .TP \fBtsv::exists\fR \fIvarname\fR \fIelement\fR Checks wether the \fIelement\fR exists in the shared variable \fIvarname\fR and returns true (1) if it does or false (0) if it doesn't\&. .TP \fBtsv::pop\fR \fIvarname\fR \fIelement\fR Returns value of the \fIelement\fR in the shared variable \fIvarname\fR and unsets the element, all in one atomic operation\&. .TP \fBtsv::move\fR \fIvarname\fR \fIoldname\fR \fInewname\fR Renames the element \fIoldname\fR to the \fInewname\fR in the shared variable \fIvarname\fR\&. This effectively performs an get/unset/set sequence of operations but all in one atomic step\&. .TP \fBtsv::incr\fR \fIvarname\fR \fIelement\fR ?count? Similar to standard Tcl \fBincr\fR command but increments the value of the \fIelement\fR in shared variaboe \fIvarname\fR instead of the Tcl variable\&. .TP \fBtsv::append\fR \fIvarname\fR \fIelement\fR \fIvalue\fR ?value \&.\&.\&.? Similar to standard Tcl \fBappend\fR command but appends one or more values to the \fIelement\fR in shared variable \fIvarname\fR instead of the Tcl variable\&. .TP \fBtsv::lock\fR \fIvarname\fR \fIarg\fR ?arg \&.\&.\&.? This command concatenates passed arguments and evaluates the resulting script under the internal mutex protection\&. During the script evaluation, the entire shared variable is locked\&. For shared variable commands within the script, internal locking is disabled so no deadlock can occur\&. It is also allowed to unset the shared variable from within the script\&. The shared variable is automatically created if it did not exists at the time of the first lock operation\&. .CS % tsv::lock foo { tsv::lappend foo bar 1 tsv::lappend foo bar 2 puts stderr [tsv::set foo bar] tsv::unset foo } .CE .TP \fBtsv::handlers\fR Returns the names of all persistent storage handlers enabled at compile time\&. See \fBARRAY COMMANDS\fR for details\&. .PP .SH "LIST COMMANDS" Those command are similar to the equivalently named Tcl command\&. The difference is that they operate on elements of shared arrays\&. .TP \fBtsv::lappend\fR \fIvarname\fR \fIelement\fR \fIvalue\fR ?value \&.\&.\&.? Similar to standard Tcl \fBlappend\fR command but appends one or more values to the \fIelement\fR in shared variable \fIvarname\fR instead of the Tcl variable\&. .TP \fBtsv::linsert\fR \fIvarname\fR \fIelement\fR \fIindex\fR \fIvalue\fR ?value \&.\&.\&.? Similar to standard Tcl \fBlinsert\fR command but inserts one or more values at the \fIindex\fR list position in the \fIelement\fR in the shared variable \fIvarname\fR instead of the Tcl variable\&. .TP \fBtsv::lreplace\fR \fIvarname\fR \fIelement\fR \fIfirst\fR \fIlast\fR ?value \&.\&.\&.? Similar to standard Tcl \fBlreplace\fR command but replaces one or more values between the \fIfirst\fR and \fIlast\fR position in the \fIelement\fR of the shared variable \fIvarname\fR instead of the Tcl variable\&. .TP \fBtsv::llength\fR \fIvarname\fR \fIelement\fR Similar to standard Tcl \fBllength\fR command but returns length of the \fIelement\fR in the shared variable \fIvarname\fR instead of the Tcl variable\&. .TP \fBtsv::lindex\fR \fIvarname\fR \fIelement\fR ?index? Similar to standard Tcl \fBlindex\fR command but returns the value at the \fIindex\fR list position of the \fIelement\fR from the shared variable \fIvarname\fR instead of the Tcl variable\&. .TP \fBtsv::lrange\fR \fIvarname\fR \fIelement\fR \fIfrom\fR \fIto\fR Similar to standard Tcl \fBlrange\fR command but returns values between \fIfrom\fR and \fIto\fR list positions from the \fIelement\fR in the shared variable \fIvarname\fR instead of the Tcl variable\&. .TP \fBtsv::lsearch\fR \fIvarname\fR \fIelement\fR ?options? \fIpattern\fR Similar to standard Tcl \fBlsearch\fR command but searches the \fIelement\fR in the shared variable \fIvarname\fR instead of the Tcl variable\&. .TP \fBtsv::lset\fR \fIvarname\fR \fIelement\fR \fIindex\fR ?index \&.\&.\&.? \fIvalue\fR Similar to standard Tcl \fBlset\fR command but sets the \fIelement\fR in the shared variable \fIvarname\fR instead of the Tcl variable\&. .TP \fBtsv::lpop\fR \fIvarname\fR \fIelement\fR ?index? Similar to the standard Tcl \fBlindex\fR command but in addition to returning, it also splices the value out of the \fIelement\fR from the shared variable \fIvarname\fR in one atomic operation\&. In contrast to the Tcl \fBlindex\fR command, this command returns no value to the caller\&. .TP \fBtsv::lpush\fR \fIvarname\fR \fIelement\fR ?index? This command performes the opposite of the \fBtsv::lpop\fR command\&. As its counterpart, it returns no value to the caller\&. .PP .SH "ARRAY COMMANDS" This command supports most of the options of the standard Tcl \fBarray\fR command\&. In addition to those, it allows binding a shared variable to some persisten storage databases\&. Currently the persistent options supported are the famous GNU Gdbm and LMDB\&. These options have to be selected during the package compilation time\&. The implementation provides hooks for defining other persistency layers, if needed\&. .TP \fBtsv::array set\fR \fIvarname\fR \fIlist\fR Does the same as standard Tcl \fBarray set\fR\&. .TP \fBtsv::array get\fR \fIvarname\fR ?pattern? Does the same as standard Tcl \fBarray get\fR\&. .TP \fBtsv::array names\fR \fIvarname\fR ?pattern? Does the same as standard Tcl \fBarray names\fR\&. .TP \fBtsv::array size\fR \fIvarname\fR Does the same as standard Tcl \fBarray size\fR\&. .TP \fBtsv::array reset\fR \fIvarname\fR \fIlist\fR Does the same as standard Tcl \fBarray set\fR but it clears the \fIvarname\fR and sets new values from the list atomically\&. .TP \fBtsv::array bind\fR \fIvarname\fR \fIhandle\fR Binds the \fIvarname\fR to the persistent storage \fIhandle\fR\&. The format of the \fIhandle\fR is :
, where is "gdbm" for GNU Gdbm and "lmdb" for LMDB and
is the path to the database file\&. .TP \fBtsv::array unbind\fR \fIvarname\fR Unbinds the shared \fIarray\fR from its bound persistent storage\&. .TP \fBtsv::array isbound\fR \fIvarname\fR Returns true (1) if the shared \fIvarname\fR is bound to some persistent storage or zero (0) if not\&. .PP .SH "KEYED LIST COMMANDS" Keyed list commands are borrowed from the TclX package\&. Keyed lists provide a structured data type built upon standard Tcl lists\&. This is a functionality similar to structs in the C programming language\&. .PP A keyed list is a list in which each element contains a key and value pair\&. These element pairs are stored as lists themselves, where the key is the first element of the list, and the value is the second\&. The key-value pairs are referred to as fields\&. This is an example of a keyed list: .CS {{NAME {Frank Zappa}} {JOB {musician and composer}}} .CE Fields may contain subfields; `\&.' is the separator character\&. Subfields are actually fields where the value is another keyed list\&. Thus the following list has the top level fields ID and NAME, and subfields NAME\&.FIRST and NAME\&.LAST: .CS {ID 106} {NAME {{FIRST Frank} {LAST Zappa}}} .CE There is no limit to the recursive depth of subfields, allowing one to build complex data structures\&. Keyed lists are constructed and accessed via a number of commands\&. All keyed list management commands take the name of the variable containing the keyed list as an argument (i\&.e\&. passed by reference), rather than passing the list directly\&. .TP \fBtsv::keyldel\fR \fIvarname\fR \fIkeylist\fR \fIkey\fR Delete the field specified by \fIkey\fR from the keyed list \fIkeylist\fR in the shared variable \fIvarname\fR\&. This removes both the key and the value from the keyed list\&. .TP \fBtsv::keylget\fR \fIvarname\fR \fIkeylist\fR \fIkey\fR ?retvar? Return the value associated with \fIkey\fR from the keyed list \fIkeylist\fR in the shared variable \fIvarname\fR\&. If the optional \fIretvar\fR is not specified, then the value will be returned as the result of the command\&. In this case, if key is not found in the list, an error will result\&. .sp If \fIretvar\fR is specified and \fIkey\fR is in the list, then the value is returned in the variable \fIretvar\fR and the command returns 1 if the key was present within the list\&. If \fIkey\fR isn't in the list, the command will return 0, and \fIretvar\fR will be left unchanged\&. If {} is specified for \fIretvar\fR, the value is not returned, allowing the Tcl programmer to determine if a \fIkey\fR is present in a keyed list without setting a variable as a side-effect\&. .TP \fBtsv::keylkeys\fR \fIvarname\fR \fIkeylist\fR ?key? Return the a list of the keys in the keyed list \fIkeylist\fR in the shared variable \fIvarname\fR\&. If \fIkey\fR is specified, then it is the name of a key field who's subfield keys are to be retrieved\&. .TP \fBtsv::keylset\fR \fIvarname\fR \fIkeylist\fR \fIkey\fR \fIvalue\fR ?key value\&.\&.? Set the value associated with \fIkey\fR, in the keyed list \fIkeylist\fR to \fIvalue\fR\&. If the \fIkeylist\fR does not exists, it is created\&. If \fIkey\fR is not currently in the list, it will be added\&. If it already exists, \fIvalue\fR replaces the existing value\&. Multiple keywords and values may be specified, if desired\&. .PP .SH DISCUSSION The current implementation of thread shared variables allows for easy and convenient access to data shared between different threads\&. Internally, the data is stored in Tcl objects and all package commands operate on internal data representation, thus minimizing shimmering and improving performance\&. Special care has been taken to assure that all object data is properly locked and deep-copied when moving objects between threads\&. .PP Due to the internal design of the Tcl core, there is no provision of full integration of shared variables within the Tcl syntax, unfortunately\&. All access to shared data must be performed with the supplied package commands\&. Also, variable traces are not supported\&. But even so, benefits of easy, simple and safe shared data manipulation outweights imposed limitations\&. .SH CREDITS Thread shared variables are inspired by the nsv interface found in AOLserver, a highly scalable Web server from America Online\&. .SH "SEE ALSO" thread, tpool, ttrace .SH KEYWORDS locking, synchronization, thread shared data, threads thread2.8.0/doc/man/tpool.n0000644003604700454610000004145112726254163014157 0ustar dgp771div'\" '\" Generated from file '' by tcllib/doctools with format 'nroff' '\" .TH "tpool" n 2\&.8 "Tcl Threading" .\" The -*- nroff -*- definitions below are for supplemental macros used .\" in Tcl/Tk manual entries. .\" .\" .AP type name in/out ?indent? .\" Start paragraph describing an argument to a library procedure. .\" type is type of argument (int, etc.), in/out is either "in", "out", .\" or "in/out" to describe whether procedure reads or modifies arg, .\" and indent is equivalent to second arg of .IP (shouldn't ever be .\" needed; use .AS below instead) .\" .\" .AS ?type? ?name? .\" Give maximum sizes of arguments for setting tab stops.

It allows you to post jobs to worker threads and wait for their completion\&. The threadpool implementation is Tcl event-loop aware\&. That means that any time a caller is forced to wait for an event (job being completed or a worker thread becoming idle or initialized), the implementation will enter the event loop and allow for servicing of other pending file or timer (or any other supported) events\&. .SH COMMANDS .TP \fBtpool::create\fR ?options? This command creates new threadpool\&. It accepts several options as key-value pairs\&. Options are used to tune some threadpool parameters\&. The command returns the ID of the newly created threadpool\&. .sp Following options are supported: .RS .TP \fB-minworkers\fR \fInumber\fR Minimum number of worker threads needed for this threadpool instance\&. During threadpool creation, the implementation will create somany worker threads upfront and will keep at least number of them alive during the lifetime of the threadpool instance\&. Default value of this parameter is 0 (zero)\&. which means that a newly threadpool will have no worker threads initialy\&. All worker threads will be started on demand by callers running \fBtpool::post\fR command and posting jobs to the job queue\&. .TP \fB-maxworkers\fR \fInumber\fR Maximum number of worker threads allowed for this threadpool instance\&. If a new job is pending and there are no idle worker threads available, the implementation will try to create new worker thread\&. If the number of available worker threads is lower than the given number, new worker thread will start\&. The caller will automatically enter the event loop and wait until the worker thread has initialized\&. If\&. however, the number of available worker threads is equal to the given number, the caller will enter the event loop and wait for the first worker thread to get idle, thus ready to run the job\&. Default value of this parameter is 4 (four), which means that the threadpool instance will allow maximum of 4 worker threads running jobs or being idle waiting for new jobs to get posted to the job queue\&. .TP \fB-idletime\fR \fIseconds\fR Time in seconds an idle worker thread waits for the job to get posted to the job queue\&. If no job arrives during this interval and the time expires, the worker thread will check the number of currently available worker threads and if the number is higher than the number set by the \fBminthreads\fR option, it will exit\&. If an \fBexitscript\fR has been defined, the exiting worker thread will first run the script and then exit\&. Errors from the exit script, if any, are ignored\&. .sp The idle worker thread is not servicing the event loop\&. If you, however, put the worker thread into the event loop, by evaluating the \fBvwait\fR or other related Tcl commands, the worker thread will not be in the idle state, hence the idle timer will not be taken into account\&. Default value for this option is unspecified\&. .TP \fB-initcmd\fR \fIscript\fR Sets a Tcl script used to initialize new worker thread\&. This is usually used to load packages and commands in the worker, set default variables, create namespaces, and such\&. If the passed script runs into a Tcl error, the worker will not be created and the initiating command (either the \fBtpool::create\fR or \fBtpool::post\fR) will throw error\&. Default value for this option is unspecified, hence, the Tcl interpreter of the worker thread will contain just the initial set of Tcl commands\&. .TP \fB-exitcmd\fR \fIscript\fR Sets a Tcl script run when the idle worker thread exits\&. This is normaly used to cleanup the state of the worker thread, release reserved resources, cleanup memory and such\&. Default value for this option is unspecified, thus no Tcl script will run on the worker thread exit\&. .RE .sp .TP \fBtpool::names\fR This command returns a list of IDs of threadpools created with the \fBtpool::create\fR command\&. If no threadpools were found, the command will return empty list\&. .TP \fBtpool::post\fR ?-detached? ?-nowait? \fItpool\fR \fIscript\fR This command sends a \fIscript\fR to the target \fItpool\fR threadpool for execution\&. The script will be executed in the first available idle worker thread\&. If there are no idle worker threads available, the command will create new one, enter the event loop and service events until the newly created thread is initialized\&. If the current number of worker threads is equal to the maximum number of worker threads, as defined during the threadpool creation, the command will enter the event loop and service events while waiting for one of the worker threads to become idle\&. If the optional ?-nowait? argument is given, the command will not wait for one idle worker\&. It will just place the job in the pool's job queue and return immediately\&. .sp The command returns the ID of the posted job\&. This ID is used for subsequent \fBtpool::wait\fR, \fBtpool::get\fR and \fBtpool::cancel\fR commands to wait for and retrieve result of the posted script, or cancel the posted job respectively\&. If the optional ?-detached? argument is specified, the command will post a detached job\&. A detached job can not be cancelled or waited upon and is not identified by the job ID\&. .sp If the threadpool \fItpool\fR is not found in the list of active thread pools, the command will throw error\&. The error will also be triggered if the newly created worker thread fails to initialize\&. .TP \fBtpool::wait\fR \fItpool\fR \fIjoblist\fR ?varname? This command waits for one or many jobs, whose job IDs are given in the \fIjoblist\fR to get processed by the worker thread(s)\&. If none of the specified jobs are ready, the command will enter the event loop, service events and wait for the first job to get ready\&. .sp The command returns the list of completed job IDs\&. If the optional variable ?varname? is given, it will be set to the list of jobs in the \fIjoblist\fR which are still pending\&. If the threadpool \fItpool\fR is not found in the list of active thread pools, the command will throw error\&. .TP \fBtpool::cancel\fR \fItpool\fR \fIjoblist\fR ?varname? This command cancels the previously posted jobs given by the \fIjoblist\fR to the pool \fItpool\fR\&. Job cancellation succeeds only for job still waiting to be processed\&. If the job is already being executed by one of the worker threads, the job will not be cancelled\&. The command returns the list of cancelled job IDs\&. If the optional variable ?varname? is given, it will be set to the list of jobs in the \fIjoblist\fR which were not cancelled\&. If the threadpool \fItpool\fR is not found in the list of active thread pools, the command will throw error\&. .TP \fBtpool::get\fR \fItpool\fR \fIjob\fR This command retrieves the result of the previously posted \fIjob\fR\&. Only results of jobs waited upon with the \fBtpool::wait\fR command can be retrieved\&. If the execution of the script resulted in error, the command will throw the error and update the \fBerrorInfo\fR and \fBerrorCode\fR variables correspondingly\&. If the pool \fItpool\fR is not found in the list of threadpools, the command will throw error\&. If the job \fIjob\fR is not ready for retrieval, because it is currently being executed by the worker thread, the command will throw error\&. .TP \fBtpool::preserve\fR \fItpool\fR Each call to this command increments the reference counter of the threadpool \fItpool\fR by one (1)\&. Command returns the value of the reference counter after the increment\&. By incrementing the reference counter, the caller signalizes that he/she wishes to use the resource for a longer period of time\&. .TP \fBtpool::release\fR \fItpool\fR Each call to this command decrements the reference counter of the threadpool \fItpool\fR by one (1)\&.Command returns the value of the reference counter after the decrement\&. When the reference counter reaches zero (0), the threadpool \fItpool\fR is marked for termination\&. You should not reference the threadpool after the \fBtpool::release\fR command returns zero\&. The \fItpool\fR handle goes out of scope and should not be used any more\&. Any following reference to the same threadpool handle will result in Tcl error\&. .TP \fBtpool::suspend\fR \fItpool\fR Suspends processing work on this queue\&. All pool workers are paused but additional work can be added to the pool\&. Note that adding the additional work will not increase the number of workers dynamically as the pool processing is suspended\&. Number of workers is maintained to the count that was found prior suspending worker activity\&. If you need to assure certain number of worker threads, use the \fBminworkers\fR option of the \fBtpool::create\fR command\&. .TP \fBtpool::resume\fR \fItpool\fR Resume processing work on this queue\&. All paused (suspended) workers are free to get work from the pool\&. Note that resuming pool operation will just let already created workers to proceed\&. It will not create additional worker threads to handle the work posted to the pool's work queue\&. .PP .SH DISCUSSION Threadpool is one of the most common threading paradigm when it comes to server applications handling a large number of relatively small tasks\&. A very simplistic model for building a server application would be to create a new thread each time a request arrives and service the request in the new thread\&. One of the disadvantages of this approach is that the overhead of creating a new thread for each request is significant; a server that created a new thread for each request would spend more time and consume more system resources in creating and destroying threads than in processing actual user requests\&. In addition to the overhead of creating and destroying threads, active threads consume system resources\&. Creating too many threads can cause the system to run out of memory or trash due to excessive memory consumption\&. .PP A thread pool offers a solution to both the problem of thread life-cycle overhead and the problem of resource trashing\&. By reusing threads for multiple tasks, the thread-creation overhead is spread over many tasks\&. As a bonus, because the thread already exists when a request arrives, the delay introduced by thread creation is eliminated\&. Thus, the request can be serviced immediately\&. Furthermore, by properly tuning the number of threads in the thread pool, resource thrashing may also be eliminated by forcing any request to wait until a thread is available to process it\&. .SH "SEE ALSO" thread, tsv, ttrace .SH KEYWORDS thread, threadpool thread2.8.0/doc/man/thread.n0000644003604700454610000007555612726254163014306 0ustar dgp771div'\" '\" Generated from file '' by tcllib/doctools with format 'nroff' '\" .TH "thread" n 2\&.8 "Tcl Threading" .\" The -*- nroff -*- definitions below are for supplemental macros used .\" in Tcl/Tk manual entries. .\" .\" .AP type name in/out ?indent? .\" Start paragraph describing an argument to a library procedure. .\" type is type of argument (int, etc.), in/out is either "in", "out", .\" or "in/out" to describe whether procedure reads or modifies arg, .\" and indent is equivalent to second arg of .IP (shouldn't ever be .\" needed; use .AS below instead) .\" .\" .AS ?type? ?name? .\" Give maximum sizes of arguments for setting tab stops.

.sp .BE .SH DESCRIPTION The \fBthread\fR extension creates threads that contain Tcl interpreters, and it lets you send scripts to those threads for evaluation\&. Additionaly, it provides script-level access to basic thread synchronization primitives, like mutexes and condition variables\&. .SH COMMANDS This section describes commands for creating and destroying threads and sending scripts to threads for evaluation\&. .TP \fBthread::create\fR ?-joinable? ?-preserved? ?script? This command creates a thread that contains a Tcl interpreter\&. The Tcl interpreter either evaluates the optional \fBscript\fR, if specified, or it waits in the event loop for scripts that arrive via the \fBthread::send\fR command\&. The result, if any, of the optional \fBscript\fR is never returned to the caller\&. The result of \fBthread::create\fR is the ID of the thread\&. This is the opaque handle which identifies the newly created thread for all other package commands\&. The handle of the thread goes out of scope automatically when thread is marked for exit (see the \fBthread::release\fR command below)\&. .sp If the optional \fBscript\fR argument contains the \fBthread::wait\fR command the thread will enter into the event loop\&. If such command is not found in the \fBscript\fR the thread will run the \fBscript\fR to the end and exit\&. In that case, the handle may be safely ignored since it refers to a thread which does not exists any more at the time when the command returns\&. .sp Using flag \fB-joinable\fR it is possible to create a joinable thread, i\&.e\&. one upon whose exit can be waited upon by using \fBthread::join\fR command\&. Note that failure to join a thread created with \fB-joinable\fR flag results in resource and memory leaks\&. .sp Threads created by the \fBthread::create\fR cannot be destroyed forcefully\&. Consequently, there is no corresponding thread destroy command\&. A thread may only be released using the \fBthread::release\fR and if its internal reference count drops to zero, the thread is marked for exit\&. This kicks the thread out of the event loop servicing and the thread continues to execute commands passed in the \fBscript\fR argument, following the \fBthread::wait\fR command\&. If this was the last command in the script, as usualy the case, the thread will exit\&. .sp It is possible to create a situation in which it may be impossible to terminate the thread, for example by putting some endless loop after the \fBthread::wait\fR or entering the event loop again by doing an vwait-type of command\&. In such cases, the thread may never exit\&. This is considered to be a bad practice and should be avoided if possible\&. This is best illustrated by the example below: .CS # You should never do \&.\&.\&. set tid [thread::create { package require Http thread::wait vwait forever ; # <-- this! }] .CE .IP The thread created in the above example will never be able to exit\&. After it has been released with the last matching \fBthread::release\fR call, the thread will jump out of the \fBthread::wait\fR and continue to execute commands following\&. It will enter \fBvwait\fR command and wait endlessly for events\&. There is no way one can terminate such thread, so you wouldn't want to do this! .sp Each newly created has its internal reference counter set to 0 (zero), i\&.e\&. it is unreserved\&. This counter gets incremented by a call to \fBthread::preserve\fR and decremented by a call to \fBthread::release\fR command\&. These two commands implement simple but effective thread reservation system and offer predictable and controllable thread termination capabilities\&. It is however possible to create initialy preserved threads by using flag \fB-preserved\fR of the \fBthread::create\fR command\&. Threads created with this flag have the initial value of the reference counter of 1 (one), and are thus initially marked reserved\&. .TP \fBthread::preserve\fR ?id? This command increments the thread reference counter\&. Each call to this command increments the reference counter by one (1)\&. Command returns the value of the reference counter after the increment\&. If called with the optional thread \fBid\fR, the command preserves the given thread\&. Otherwise the current thread is preserved\&. .sp With reference counting, one can implement controlled access to a shared Tcl thread\&. By incrementing the reference counter, the caller signalizes that he/she wishes to use the thread for a longer period of time\&. By decrementing the counter, caller signalizes that he/she has finished using the thread\&. .TP \fBthread::release\fR ?-wait? ?id? This command decrements the thread reference counter\&. Each call to this command decrements the reference counter by one (1)\&. If called with the optional thread \fBid\fR, the command releases the given thread\&. Otherwise, the current thread is released\&. Command returns the value of the reference counter after the decrement\&. When the reference counter reaches zero (0), the target thread is marked for termination\&. You should not reference the thread after the \fBthread::release\fR command returns zero or negative integer\&. The handle of the thread goes out of scope and should not be used any more\&. Any following reference to the same thread handle will result in Tcl error\&. .sp Optional flag \fB-wait\fR instructs the caller thread to wait for the target thread to exit, if the effect of the command would result in termination of the target thread, i\&.e\&. if the return result would be zero (0)\&. Without the flag, the caller thread does not wait for the target thread to exit\&. Care must be taken when using the \fB-wait\fR, since this may block the caller thread indefinitely\&. This option has been implemented for some special uses of the extension and is deprecated for regular use\&. Regular users should create joinable threads by using the \fB-joinable\fR option of the \fBthread::create\fR command and the \fBthread::join\fR to wait for thread to exit\&. .TP \fBthread::id\fR This command returns the ID of the current thread\&. .TP \fBthread::errorproc\fR ?procname? This command sets a handler for errors that occur in scripts sent asynchronously, using the \fB-async\fR flag of the \fBthread::send\fR command, to other threads\&. If no handler is specified, the current handler is returned\&. The empty string resets the handler to default (unspecified) value\&. An uncaught error in a thread causes an error message to be sent to the standard error channel\&. This default reporting scheme can be changed by registering a procedure which is called to report the error\&. The \fIprocname\fR is called in the interpreter that invoked the \fBthread::errorproc\fR command\&. The \fIprocname\fR is called like this: .CS myerrorproc thread_id errorInfo .CE .TP \fBthread::cancel\fR ?-unwind? \fIid\fR ?result? This command requires Tcl version 8\&.6 or higher\&. .sp Cancels the script being evaluated in the thread given by the \fIid\fR parameter\&. Without the \fB-unwind\fR switch the evaluation stack for the interpreter is unwound until an enclosing catch command is found or there are no further invocations of the interpreter left on the call stack\&. With the \fB-unwind\fR switch the evaluation stack for the interpreter is unwound without regard to any intervening catch command until there are no further invocations of the interpreter left on the call stack\&. If \fIresult\fR is present, it will be used as the error message string; otherwise, a default error message string will be used\&. .TP \fBthread::unwind\fR Use of this command is deprecated in favour of more advanced thread reservation system implemented with \fBthread::preserve\fR and \fBthread::release\fR commands\&. Support for \fBthread::unwind\fR command will dissapear in some future major release of the extension\&. .sp This command stops a prior \fBthread::wait\fR command\&. Execution of the script passed to newly created thread will continue from the \fBthread::wait\fR command\&. If \fBthread::wait\fR was the last command in the script, the thread will exit\&. The command returns empty result but may trigger Tcl error with the message "target thread died" in some situations\&. .TP \fBthread::exit\fR ?status? Use of this command is deprecated in favour of more advanced thread reservation system implemented with \fBthread::preserve\fR and \fBthread::release\fR commands\&. Support for \fBthread::exit\fR command will dissapear in some future major release of the extension\&. .sp This command forces a thread stuck in the \fBthread::wait\fR command to unconditionaly exit\&. The thread's exit status defaults to 666 and can be specified using the optional \fIstatus\fR argument\&. The execution of \fBthread::exit\fR command is guaranteed to leave the program memory in the unconsistent state, produce memory leaks and otherwise affect other subsytem(s) of the Tcl application in an unpredictable manner\&. The command returns empty result but may trigger Tcl error with the message "target thread died" in some situations\&. .TP \fBthread::names\fR This command returns a list of thread IDs\&. These are only for threads that have been created via \fBthread::create\fR command\&. If your application creates other threads at the C level, they are not reported by this command\&. .TP \fBthread::exists\fR \fIid\fR Returns true (1) if thread given by the \fIid\fR parameter exists, false (0) otherwise\&. This applies only for threads that have been created via \fBthread::create\fR command\&. .TP \fBthread::send\fR ?-async? ?-head? \fIid\fR \fIscript\fR ?varname? This command passes a \fIscript\fR to another thread and, optionally, waits for the result\&. If the \fB-async\fR flag is specified, the command does not wait for the result and it returns empty string\&. The target thread must enter it's event loop in order to receive scripts sent via this command\&. This is done by default for threads created without a startup script\&. Threads can enter the event loop explicitly by calling \fBthread::wait\fR or any other relevant Tcl/Tk command, like \fBupdate\fR, \fBvwait\fR, etc\&. .sp Optional \fBvarname\fR specifies name of the variable to store the result of the \fIscript\fR\&. Without the \fB-async\fR flag, the command returns the evaluation code, similarily to the standard Tcl \fBcatch\fR command\&. If, however, the \fB-async\fR flag is specified, the command returns immediately and caller can later \fBvwait\fR on ?varname? to get the result of the passed \fIscript\fR .CS set t1 [thread::create] set t2 [thread::create] thread::send -async $t1 "set a 1" result thread::send -async $t2 "set b 2" result for {set i 0} {$i < 2} {incr i} { vwait result } .CE .IP In the above example, two threads were fed work and both of them were instructed to signalize the same variable "result" in the calling thread\&. The caller entered the event loop twice to get both results\&. Note, however, that the order of the received results may vary, depending on the current system load, type of work done, etc, etc\&. .sp Many threads can simultaneously send scripts to the target thread for execution\&. All of them are entered into the event queue of the target thread and executed on the FIFO basis, intermingled with optional other events pending in the event queue of the target thread\&. Using the optional ?-head? switch, scripts posted to the thread's event queue can be placed on the head, instead on the tail of the queue, thus being executed in the LIFO fashion\&. .TP \fBthread::broadcast\fR \fIscript\fR This command passes a \fIscript\fR to all threads created by the package for execution\&. It does not wait for response from any of the threads\&. .TP \fBthread::wait\fR This enters the event loop so a thread can receive messages from the \fBthread::send\fR command\&. This command should only be used within the script passed to the \fBthread::create\fR\&. It should be the very last command in the script\&. If this is not the case, the exiting thread will continue executing the script lines past the \fBthread::wait\fR which is usually not what you want and/or expect\&. .CS set t1 [thread::create { # # Do some initialization work here # thread::wait ; # Enter the event loop }] .CE .TP \fBthread::eval\fR ?-lock mutex? \fIarg\fR ?arg \&.\&.\&.? This command concatenates passed arguments and evaluates the resulting script under the mutex protection\&. If no mutex is specified by using the ?-lock mutex? optional argument, the internal static mutex is used\&. .TP \fBthread::join\fR \fIid\fR This command waits for the thread with ID \fIid\fR to exit and then returns it's exit code\&. Errors will be returned for threads which are not joinable or already waited upon by another thread\&. Upon the join the handle of the thread has gone out of scope and should not be used any more\&. .TP \fBthread::configure\fR \fIid\fR ?option? ?value? ?\&.\&.\&.? This command configures various low-level aspects of the thread with ID \fIid\fR in the similar way as the standard Tcl command \fBfconfigure\fR configures some Tcl channel options\&. Options currently supported are: \fB-eventmark\fR and \fB-unwindonerror\fR\&. .sp The \fB-eventmark\fR option, when set, limits the number of asynchronously posted scripts to the thread event loop\&. The \fBthread::send -async\fR command will block until the number of pending scripts in the event loop does not drop below the value configured with \fB-eventmark\fR\&. Default value for the \fB-eventmark\fR is 0 (zero) which effectively disables the checking, i\&.e\&. allows for unlimited number of posted scripts\&. .sp The \fB-unwindonerror\fR option, when set, causes the target thread to unwind if the result of the script processing resulted in error\&. Default value for the \fB-unwindonerror\fR is 0 (false), i\&.e\&. thread continues to process scripts after one of the posted scripts fails\&. .TP \fBthread::transfer\fR \fIid\fR \fIchannel\fR This moves the specified \fIchannel\fR from the current thread and interpreter to the main interpreter of the thread with the given \fIid\fR\&. After the move the current interpreter has no access to the channel any more, but the main interpreter of the target thread will be able to use it from now on\&. The command waits until the other thread has incorporated the channel\&. Because of this it is possible to deadlock the participating threads by commanding the other through a synchronous \fBthread::send\fR to transfer a channel to us\&. This easily extends into longer loops of threads waiting for each other\&. Other restrictions: the channel in question must not be shared among multiple interpreters running in the sending thread\&. This automatically excludes the special channels for standard input, output and error\&. .sp Due to the internal Tcl core implementation and the restriction on transferring shared channels, one has to take extra measures when transferring socket channels created by accepting the connection out of the \fBsocket\fR commands callback procedures: .CS socket -server _Accept 2200 proc _Accept {s ipaddr port} { after idle [list Accept $s $ipaddr $port] } proc Accept {s ipaddr port} { set tid [thread::create] thread::transfer $tid $s } .CE .TP \fBthread::detach\fR \fIchannel\fR This detaches the specified \fIchannel\fR from the current thread and interpreter\&. After that, the current interpreter has no access to the channel any more\&. The channel is in the parked state until some other (or the same) thread attaches the channel again with \fBthread::attach\fR\&. Restrictions: same as for transferring shared channels with the \fBthread::transfer\fR command\&. .TP \fBthread::attach\fR \fIchannel\fR This attaches the previously detached \fIchannel\fR in the current thread/interpreter\&. For already existing channels, the command does nothing, i\&.e\&. it is not an error to attach the same channel more than once\&. The first operation will actualy perform the operation, while all subsequent operation will just do nothing\&. Command throws error if the \fIchannel\fR cannot be found in the list of detached channels and/or in the current interpreter\&. .TP \fBthread::mutex\fR Mutexes are most common thread synchronization primitives\&. They are used to synchronize access from two or more threads to one or more shared resources\&. This command provides script-level access to exclusive and/or recursive mutexes\&. Exclusive mutexes can be locked only once by one thread, while recursive mutexes can be locked many times by the same thread\&. For recursive mutexes, number of lock and unlock operations must match, otherwise, the mutex will never be released, which would lead to various deadlock situations\&. .sp Care has to be taken when using mutexes in an multithreading program\&. Improper use of mutexes may lead to various deadlock situations, especially when using exclusive mutexes\&. .sp The \fBthread::mutex\fR command supports following subcommands and options: .RS .TP \fBthread::mutex\fR \fBcreate\fR ?-recursive? Creates the mutex and returns it's opaque handle\&. This handle should be used for any future reference to the newly created mutex\&. If no optional ?-recursive? argument was specified, the command creates the exclusive mutex\&. With the ?-recursive? argument, the command creates a recursive mutex\&. .TP \fBthread::mutex\fR \fBdestroy\fR \fImutex\fR Destroys the \fImutex\fR\&. Mutex should be in unlocked state before the destroy attempt\&. If the mutex is locked, the command will throw Tcl error\&. .TP \fBthread::mutex\fR \fBlock\fR \fImutex\fR Locks the \fImutex\fR\&. Locking the exclusive mutex may throw Tcl error if on attempt to lock the same mutex twice from the same thread\&. If your program logic forces you to lock the same mutex twice or more from the same thread (this may happen in recursive procedure invocations) you should consider using the recursive mutexes\&. .TP \fBthread::mutex\fR \fBunlock\fR \fImutex\fR Unlocks the \fImutex\fR so some other thread may lock it again\&. Attempt to unlock the already unlocked mutex will throw Tcl error\&. .RE .sp .TP \fBthread::rwmutex\fR This command creates many-readers/single-writer mutexes\&. Reader/writer mutexes allow you to serialize access to a shared resource more optimally\&. In situations where a shared resource gets mostly read and seldom modified, you might gain some performace by using reader/writer mutexes instead of exclusive or recursive mutexes\&. .sp For reading the resource, thread should obtain a read lock on the resource\&. Read lock is non-exclusive, meaning that more than one thread can obtain a read lock to the same resource, without waiting on other readers\&. For changing the resource, however, a thread must obtain a exclusive write lock\&. This lock effectively blocks all threads from gaining the read-lock while the resource is been modified by the writer thread\&. Only after the write lock has been released, the resource may be read-locked again\&. .sp The \fBthread::rwmutex\fR command supports following subcommands and options: .RS .TP \fBthread::rwmutex\fR \fBcreate\fR Creates the reader/writer mutex and returns it's opaque handle\&. This handle should be used for any future reference to the newly created mutex\&. .TP \fBthread::rwmutex\fR \fBdestroy\fR \fImutex\fR Destroys the reader/writer \fImutex\fR\&. If the mutex is already locked, attempt to destroy it will throw Tcl error\&. .TP \fBthread::rwmutex\fR \fBrlock\fR \fImutex\fR Locks the \fImutex\fR for reading\&. More than one thread may read-lock the same \fImutex\fR at the same time\&. .TP \fBthread::rwmutex\fR \fBwlock\fR \fImutex\fR Locks the \fImutex\fR for writing\&. Only one thread may write-lock the same \fImutex\fR at the same time\&. Attempt to write-lock same \fImutex\fR twice from the same thread will throw Tcl error\&. .TP \fBthread::rwmutex\fR \fBunlock\fR \fImutex\fR Unlocks the \fImutex\fR so some other thread may lock it again\&. Attempt to unlock already unlocked \fImutex\fR will throw Tcl error\&. .RE .sp .TP \fBthread::cond\fR This command provides script-level access to condition variables\&. A condition variable creates a safe environment for the program to test some condition, sleep on it when false and be awakened when it might have become true\&. A condition variable is always used in the conjuction with an exclusive mutex\&. If you attempt to use other type of mutex in conjuction with the condition variable, a Tcl error will be thrown\&. .sp The command supports following subcommands and options: .RS .TP \fBthread::cond\fR \fBcreate\fR Creates the condition variable and returns it's opaque handle\&. This handle should be used for any future reference to newly created condition variable\&. .TP \fBthread::cond\fR \fBdestroy\fR \fIcond\fR Destroys condition variable \fIcond\fR\&. Extreme care has to be taken that nobody is using (i\&.e\&. waiting on) the condition variable, otherwise unexpected errors may happen\&. .TP \fBthread::cond\fR \fBnotify\fR \fIcond\fR Wakes up all threads waiting on the condition variable \fIcond\fR\&. .TP \fBthread::cond\fR \fBwait\fR \fIcond\fR \fImutex\fR ?ms? This command is used to suspend program execution until the condition variable \fIcond\fR has been signalled or the optional timer has expired\&. The exclusive \fImutex\fR must be locked by the calling thread on entrance to this command\&. If the mutex is not locked, Tcl error is thrown\&. While waiting on the \fIcond\fR, the command releases \fImutex\fR\&. Before returning to the calling thread, the command re-acquires the \fImutex\fR again\&. Unlocking the \fImutex\fR and waiting on the condition variable \fIcond\fR is done atomically\&. .sp The \fBms\fR command option, if given, must be an integer specifying time interval in milliseconds the command waits to be signalled\&. Otherwise the command waits on condition notify forever\&. .sp In multithreading programs, there are many situations where a thread has to wait for some event to happen until it is allowed to proceed\&. This is usually accomplished by repeatedly testing a condition under the mutex protection and waiting on the condition variable until the condition evaluates to true: .CS set mutex [thread::mutex create] set cond [thread::cond create] thread::mutex lock $mutex while {} { thread::cond wait $cond $mutex } # Do some work under mutex protection thread::mutex unlock $mutex .CE .IP Repeated testing of the condition is needed since the condition variable may get signalled without the condition being actually changed (spurious thread wake-ups, for example)\&. .RE .PP .SH DISCUSSION The fundamental threading model in Tcl is that there can be one or more Tcl interpreters per thread, but each Tcl interpreter should only be used by a single thread which created it\&. A "shared memory" abstraction is awkward to provide in Tcl because Tcl makes assumptions about variable and data ownership\&. Therefore this extension supports a simple form of threading where the main thread can manage several background, or "worker" threads\&. For example, an event-driven server can pass requests to worker threads, and then await responses from worker threads or new client requests\&. Everything goes through the common Tcl event loop, so message passing between threads works naturally with event-driven I/O, \fBvwait\fR on variables, and so forth\&. For the transfer of bulk information it is possible to move channels between the threads\&. .PP For advanced multithreading scripts, script-level access to two basic synchronization primitives, mutex and condition variables, is also supported\&. .SH "SEE ALSO" \fIhttp://www\&.tcl\&.tk/doc/howto/thread_model\&.html\fR, tpool, tsv, ttrace .SH KEYWORDS events, message passing, mutex, synchronization, thread thread2.8.0/doc/format.tcl0000644003604700454610000000146511555575712014072 0ustar dgp771div#!/usr/local/bin/tclsh set mydir [file dirname [info script]] lappend auto_path /usr/local/lib package req doctools doctools::new dt set wd [pwd] cd $mydir file rename html htm set code [catch { set f [open man.macros] set m [read $f] close $f foreach file [glob -nocomplain *.man] { set xx [file root $file] set f [open $xx.man] set t [read $f] close $f foreach {fmt ext dir} {nroff n man html html htm} { dt configure -format $fmt set o [dt format $t] set f [open $dir/$xx.$ext w] if {$fmt == "nroff"} { set o [string map [list {.so man.macros} $m] $o] } puts $f $o close $f } } } err] file rename htm html cd $wd if {$code} { error $err } exit 0 thread2.8.0/doc/ttrace.man0000644003604700454610000002112312736734044014043 0ustar dgp771div[comment {-*- tcl -*- doctools manpage}] [manpage_begin ttrace n 2.8] [moddesc {Tcl Threading}] [titledesc {Trace-based interpreter initialization}] [require Tcl 8.4] [require Thread [opt 2.8]] [description] This package creates a framework for on-demand replication of the interpreter state accross threads in an multithreading application. It relies on the mechanics of Tcl command tracing and the Tcl [cmd unknown] command and mechanism. [para] The package requires Tcl threading extension but can be alternatively used stand-alone within the AOLserver, a scalable webserver from America Online. [para] In a nutshell, a short sample illustrating the usage of the ttrace with the Tcl threading extension: [example { % package require Ttrace 2.8.0 % set t1 [thread::create {package require Ttrace; thread::wait}] tid0x1802800 % ttrace::eval {proc test args {return test-[thread::id]}} % thread::send $t1 test test-tid0x1802800 % set t2 [thread::create {package require Ttrace; thread::wait}] tid0x1804000 % thread::send $t2 test test-tid0x1804000 }] [para] As seen from above, the [cmd ttrace::eval] and [cmd ttrace::update] commands are used to create a thread-wide definition of a simple Tcl procedure and replicate that definition to all, already existing or later created, threads. [section {USER COMMANDS}] This section describes user-level commands. Those commands can be used by script writers to control the execution of the tracing framework. [list_begin definitions] [call [cmd ttrace::eval] [arg arg] [opt {arg ...}]] This command concatenates given arguments and evaluates the resulting Tcl command with trace framework enabled. If the command execution was ok, it takes necessary steps to automatically propagate the trace epoch change to all threads in the application. For AOLserver, only newly created threads actually receive the epoch change. For the Tcl threading extension, all threads created by the extension are automatically updated. If the command execution resulted in Tcl error, no state propagation takes place. [para] This is the most important user-level command of the package as it wraps most of the commands described below. This greatly simplifies things, because user need to learn just this (one) command in order to effectively use the package. Other commands, as desribed below, are included mostly for the sake of completeness. [call [cmd ttrace::enable]] Activates all registered callbacks in the framework and starts a new trace epoch. The trace epoch encapsulates all changes done to the interpreter during the time traces are activated. [call [cmd ttrace::disable]] Deactivates all registered callbacks in the framework and closes the current trace epoch. [call [cmd ttrace::cleanup]] Used to clean-up all on-demand loaded resources in the interpreter. It effectively brings Tcl interpreter to its pristine state. [call [cmd ttrace::update] [opt epoch]] Used to refresh the state of the interpreter to match the optional trace [opt epoch]. If the optional [opt epoch] is not given, it takes the most recent trace epoch. [call [cmd ttrace::getscript]] Returns a synthetized Tcl script which may be sourced in any interpreter. This script sets the stage for the Tcl [cmd unknown] command so it can load traced resources from the in-memory database. Normally, this command is automatically invoked by other higher-level commands like [cmd ttrace::eval] and [cmd ttrace::update]. [list_end] [section {CALLBACK COMMANDS}] A word upfront: the package already includes callbacks for tracing following Tcl commands: [cmd proc], [cmd namespace], [cmd variable], [cmd load], and [cmd rename]. Additionaly, a set of callbacks for tracing resources (object, clasess) for the XOTcl v1.3.8+, an OO-extension to Tcl, is also provided. This gives a solid base for solving most of the real-life needs and serves as an example for people wanting to customize the package to cover their specific needs. [para] Below, you can find commands for registering callbacks in the framework and for writing callback scripts. These callbacks are invoked by the framework in order to gather interpreter state changes, build in-memory database, perform custom-cleanups and various other tasks. [list_begin definitions] [call [cmd ttrace::atenable] [arg cmd] [arg arglist] [arg body]] Registers Tcl callback to be activated at [cmd ttrace::enable]. Registered callbacks are activated on FIFO basis. The callback definition includes the name of the callback, [arg cmd], a list of callback arguments, [arg arglist] and the [arg body] of the callback. Effectively, this actually resembles the call interface of the standard Tcl [cmd proc] command. [call [cmd ttrace::atdisable] [arg cmd] [arg arglist] [arg body]] Registers Tcl callback to be activated at [cmd ttrace::disable]. Registered callbacks are activated on FIFO basis. The callback definition includes the name of the callback, [arg cmd], a list of callback arguments, [arg arglist] and the [arg body] of the callback. Effectively, this actually resembles the call interface of the standard Tcl [cmd proc] command. [call [cmd ttrace::addtrace] [arg cmd] [arg arglist] [arg body]] Registers Tcl callback to be activated for tracing the Tcl [cmd cmd] command. The callback definition includes the name of the Tcl command to trace, [arg cmd], a list of callback arguments, [arg arglist] and the [arg body] of the callback. Effectively, this actually resembles the call interface of the standard Tcl [cmd proc] command. [call [cmd ttrace::addscript] [arg name] [arg body]] Registers Tcl callback to be activated for building a Tcl script to be passed to other interpreters. This script is used to set the stage for the Tcl [cmd unknown] command. Registered callbacks are activated on FIFO basis. The callback definition includes the name of the callback, [arg name] and the [arg body] of the callback. [call [cmd ttrace::addresolver] [arg cmd] [arg arglist] [arg body]] Registers Tcl callback to be activated by the overloaded Tcl [cmd unknown] command. Registered callbacks are activated on FIFO basis. This callback is used to resolve the resource and load the resource in the current interpreter. [call [cmd ttrace::addcleanup] [arg body]] Registers Tcl callback to be activated by the [cmd trace::cleanup]. Registered callbacks are activated on FIFO basis. [call [cmd ttrace::addentry] [arg cmd] [arg var] [arg val]] Adds one entry to the named in-memory database. [call [cmd ttrace::getentry] [arg cmd] [arg var]] Returns the value of the entry from the named in-memory database. [call [cmd ttrace::getentries] [arg cmd] [opt pattern]] Returns names of all entries from the named in-memory database. [call [cmd ttrace::delentry] [arg cmd]] Deletes an entry from the named in-memory database. [call [cmd ttrace::preload] [arg cmd]] Registers the Tcl command to be loaded in the interpreter. Commands registered this way will always be the part of the interpreter and not be on-demand loaded by the Tcl [cmd unknown] command. [list_end] [section DISCUSSION] Common introspective state-replication approaches use a custom Tcl script to introspect the running interpreter and synthesize another Tcl script to replicate this state in some other interpreter. This package, on the contrary, uses Tcl command traces. Command traces are registered on selected Tcl commands, like [cmd proc], [cmd namespace], [cmd load] and other standard (and/or user-defined) Tcl commands. When activated, those traces build an in-memory database of created resources. This database is used as a resource repository for the (overloaded) Tcl [cmd unknown] command which creates the requested resource in the interpreter on demand. This way, users can update just one interpreter (master) in one thread and replicate that interpreter state (or part of it) to other threads/interpreters in the process. [para] Immediate benefit of such approach is the much smaller memory footprint of the application and much faster thread creation. By not actually loading all necessary procedures (and other resources) in every thread at the thread initialization time, but by deffering this to the time the resource is actually referenced, significant improvements in both memory consumption and thread initialization time can be achieved. Some tests have shown that memory footprint of an multithreading Tcl application went down more than three times and thread startup time was reduced for about 50 times. Note that your mileage may vary. Other benefits include much finer control about what (and when) gets replicated from the master to other Tcl thread/interpreters.

A thread shared variable is very similar to a Tcl array but in contrast to a Tcl array it is created in shared memory and can be accessed from many threads at the same time. Important feature of thread shared variable is that each access to the variable is internaly protected by a mutex so script programmer does not have to take care about locking the variable himself. [para] Thread shared variables are not bound to any thread explicitly. That means that when a thread which created any of thread shared variables exits, the variable and associated memory is not unset/reclaimed. User has to explicitly unset the variable to reclaim the memory consumed by the variable. [section {ELEMENT COMMANDS}] [list_begin definitions] [call [cmd tsv::names] [opt pattern]] Returns names of shared variables matching optional [opt pattern] or all known variables if pattern is ommited. [call [cmd tsv::object] [arg varname] [arg element]] Creates object accessor command for the [arg element] in the shared variable [arg varname]. Using this command, one can apply most of the other shared variable commands as method functions of the element object command. The object command is automatically deleted when the element which this command is pointing to is unset. [example { % tsv::set foo bar "A shared string" % set string [tsv::object foo bar] % $string append " appended" => A shared string appended }] [call [cmd tsv::set] [arg varname] [arg element] [opt value]] Sets the value of the [arg element] in the shared variable [arg varname] to [arg value] and returns the value to caller. The [arg value] may be ommited, in which case the command will return the current value of the element. If the element cannot be found, error is triggered. [call [cmd tsv::get] [arg varname] [arg element] [opt namedvar]] Retrieves the value of the [arg element] from the shared variable [arg varname]. If the optional argument [arg namedvar] is given, the value is stored in the named variable. Return value of the command depends of the existence of the optional argument [arg namedvar]. If the argument is ommited and the requested element cannot be found in the shared array, the command triggers error. If, however, the optional argument is given on the command line, the command returns true (1) if the element is found or false (0) if the element is not found. [call [cmd tsv::unset] [arg varname] [opt element]] Unsets the [arg element] from the shared variable [arg varname]. If the optional element is not given, it deletes the variable. [call [cmd tsv::exists] [arg varname] [arg element]] Checks wether the [arg element] exists in the shared variable [arg varname] and returns true (1) if it does or false (0) if it doesn't. [call [cmd tsv::pop] [arg varname] [arg element]] Returns value of the [arg element] in the shared variable [arg varname] and unsets the element, all in one atomic operation. [call [cmd tsv::move] [arg varname] [arg oldname] [arg newname]] Renames the element [arg oldname] to the [arg newname] in the shared variable [arg varname]. This effectively performs an get/unset/set sequence of operations but all in one atomic step. [call [cmd tsv::incr] [arg varname] [arg element] [opt count]] Similar to standard Tcl [cmd incr] command but increments the value of the [arg element] in shared variaboe [arg varname] instead of the Tcl variable. [call [cmd tsv::append] [arg varname] [arg element] [arg value] [opt {value ...}]] Similar to standard Tcl [cmd append] command but appends one or more values to the [arg element] in shared variable [arg varname] instead of the Tcl variable. [call [cmd tsv::lock] [arg varname] [arg arg] [opt {arg ...}]] This command concatenates passed arguments and evaluates the resulting script under the internal mutex protection. During the script evaluation, the entire shared variable is locked. For shared variable commands within the script, internal locking is disabled so no deadlock can occur. It is also allowed to unset the shared variable from within the script. The shared variable is automatically created if it did not exists at the time of the first lock operation. [example { % tsv::lock foo { tsv::lappend foo bar 1 tsv::lappend foo bar 2 puts stderr [tsv::set foo bar] tsv::unset foo } }] [call [cmd tsv::handlers]] Returns the names of all persistent storage handlers enabled at compile time. See [sectref {ARRAY COMMANDS}] for details. [list_end] [section {LIST COMMANDS}] Those command are similar to the equivalently named Tcl command. The difference is that they operate on elements of shared arrays. [list_begin definitions] [call [cmd tsv::lappend] [arg varname] [arg element] [arg value] [opt {value ...}]] Similar to standard Tcl [cmd lappend] command but appends one or more values to the [arg element] in shared variable [arg varname] instead of the Tcl variable. [call [cmd tsv::linsert] [arg varname] [arg element] [arg index] [arg value] [opt {value ...}]] Similar to standard Tcl [cmd linsert] command but inserts one or more values at the [arg index] list position in the [arg element] in the shared variable [arg varname] instead of the Tcl variable. [call [cmd tsv::lreplace] [arg varname] [arg element] [arg first] [arg last] [opt {value ...}]] Similar to standard Tcl [cmd lreplace] command but replaces one or more values between the [arg first] and [arg last] position in the [arg element] of the shared variable [arg varname] instead of the Tcl variable. [call [cmd tsv::llength] [arg varname] [arg element]] Similar to standard Tcl [cmd llength] command but returns length of the [arg element] in the shared variable [arg varname] instead of the Tcl variable. [call [cmd tsv::lindex] [arg varname] [arg element] [opt index]] Similar to standard Tcl [cmd lindex] command but returns the value at the [arg index] list position of the [arg element] from the shared variable [arg varname] instead of the Tcl variable. [call [cmd tsv::lrange] [arg varname] [arg element] [arg from] [arg to]] Similar to standard Tcl [cmd lrange] command but returns values between [arg from] and [arg to] list positions from the [arg element] in the shared variable [arg varname] instead of the Tcl variable. [call [cmd tsv::lsearch] [arg varname] [arg element] [opt options] [arg pattern]] Similar to standard Tcl [cmd lsearch] command but searches the [arg element] in the shared variable [arg varname] instead of the Tcl variable. [call [cmd tsv::lset] [arg varname] [arg element] [arg index] [opt {index ...}] [arg value]] Similar to standard Tcl [cmd lset] command but sets the [arg element] in the shared variable [arg varname] instead of the Tcl variable. [call [cmd tsv::lpop] [arg varname] [arg element] [opt index]] Similar to the standard Tcl [cmd lindex] command but in addition to returning, it also splices the value out of the [arg element] from the shared variable [arg varname] in one atomic operation. In contrast to the Tcl [cmd lindex] command, this command returns no value to the caller. [call [cmd tsv::lpush] [arg varname] [arg element] [opt index]] This command performes the opposite of the [cmd tsv::lpop] command. As its counterpart, it returns no value to the caller. [list_end] [section {ARRAY COMMANDS}] This command supports most of the options of the standard Tcl [cmd array] command. In addition to those, it allows binding a shared variable to some persisten storage databases. Currently the persistent options supported are the famous GNU Gdbm and LMDB. These options have to be selected during the package compilation time. The implementation provides hooks for defining other persistency layers, if needed. [list_begin definitions] [call [cmd {tsv::array set}] [arg varname] [arg list]] Does the same as standard Tcl [cmd {array set}]. [call [cmd {tsv::array get}] [arg varname] [opt pattern]] Does the same as standard Tcl [cmd {array get}]. [call [cmd {tsv::array names}] [arg varname] [opt pattern]] Does the same as standard Tcl [cmd {array names}]. [call [cmd {tsv::array size}] [arg varname]] Does the same as standard Tcl [cmd {array size}]. [call [cmd {tsv::array reset}] [arg varname] [arg list]] Does the same as standard Tcl [cmd {array set}] but it clears the [arg varname] and sets new values from the list atomically. [call [cmd {tsv::array bind}] [arg varname] [arg handle]] Binds the [arg varname] to the persistent storage [arg handle]. The format of the [arg handle] is :
, where is "gdbm" for GNU Gdbm and "lmdb" for LMDB and
is the path to the database file. [call [cmd {tsv::array unbind}] [arg varname]] Unbinds the shared [arg array] from its bound persistent storage. [call [cmd {tsv::array isbound}] [arg varname]] Returns true (1) if the shared [arg varname] is bound to some persistent storage or zero (0) if not. [list_end] [section {KEYED LIST COMMANDS}] Keyed list commands are borrowed from the TclX package. Keyed lists provide a structured data type built upon standard Tcl lists. This is a functionality similar to structs in the C programming language. [para] A keyed list is a list in which each element contains a key and value pair. These element pairs are stored as lists themselves, where the key is the first element of the list, and the value is the second. The key-value pairs are referred to as fields. This is an example of a keyed list: [example { {{NAME {Frank Zappa}} {JOB {musician and composer}}} }] Fields may contain subfields; `.' is the separator character. Subfields are actually fields where the value is another keyed list. Thus the following list has the top level fields ID and NAME, and subfields NAME.FIRST and NAME.LAST: [example { {ID 106} {NAME {{FIRST Frank} {LAST Zappa}}} }] There is no limit to the recursive depth of subfields, allowing one to build complex data structures. Keyed lists are constructed and accessed via a number of commands. All keyed list management commands take the name of the variable containing the keyed list as an argument (i.e. passed by reference), rather than passing the list directly. [list_begin definitions] [call [cmd tsv::keyldel] [arg varname] [arg keylist] [arg key]] Delete the field specified by [arg key] from the keyed list [arg keylist] in the shared variable [arg varname]. This removes both the key and the value from the keyed list. [call [cmd tsv::keylget] [arg varname] [arg keylist] [arg key] [opt retvar]] Return the value associated with [arg key] from the keyed list [arg keylist] in the shared variable [arg varname]. If the optional [arg retvar] is not specified, then the value will be returned as the result of the command. In this case, if key is not found in the list, an error will result. [para] If [arg retvar] is specified and [arg key] is in the list, then the value is returned in the variable [arg retvar] and the command returns 1 if the key was present within the list. If [arg key] isn't in the list, the command will return 0, and [arg retvar] will be left unchanged. If {} is specified for [arg retvar], the value is not returned, allowing the Tcl programmer to determine if a [arg key] is present in a keyed list without setting a variable as a side-effect. [call [cmd tsv::keylkeys] [arg varname] [arg keylist] [opt key]] Return the a list of the keys in the keyed list [arg keylist] in the shared variable [arg varname]. If [arg key] is specified, then it is the name of a key field who's subfield keys are to be retrieved. [call [cmd tsv::keylset] [arg varname] [arg keylist] [arg key] [arg value] [opt {key value..}]] Set the value associated with [arg key], in the keyed list [arg keylist] to [arg value]. If the [arg keylist] does not exists, it is created. If [arg key] is not currently in the list, it will be added. If it already exists, [arg value] replaces the existing value. Multiple keywords and values may be specified, if desired. [list_end] [section DISCUSSION] The current implementation of thread shared variables allows for easy and convenient access to data shared between different threads. Internally, the data is stored in Tcl objects and all package commands operate on internal data representation, thus minimizing shimmering and improving performance. Special care has been taken to assure that all object data is properly locked and deep-copied when moving objects between threads. [para] Due to the internal design of the Tcl core, there is no provision of full integration of shared variables within the Tcl syntax, unfortunately. All access to shared data must be performed with the supplied package commands. Also, variable traces are not supported. But even so, benefits of easy, simple and safe shared data manipulation outweights imposed limitations. [section CREDITS] Thread shared variables are inspired by the nsv interface found in AOLserver, a highly scalable Web server from America Online.

The Ttrace must now explicitly be loaded in every new thread created by [thread::create] command. The [package require Ttrace] automatically loads Thread package as well. NOTE: be sure to configure/make/make install because the pkgIndex.tcl loader file is modified. 2006-10-06 Zoran Vasiljevic * generic/threadPool.c: * generic/threadCmd.c: Removed Tcl_PkgRequire from the new thread initialization and just initialize the C-aspect of the extension by calling Therad_Init. This basically discards the last checkin, which was in a sense bad as it made thread creation very expensive operation. * pkgIndex.tcl.in: Added separate handling for Ttrace loading. Now, users needing Ttrace caps must "package require Ttrace" which in turn automatically calls "package require Thread". Also, each new thread created by [thread::create] must be initialized for Ttrace by calling the [package require Ttrace]. On the other hand, the "package require Thread" is only necessary to first-load the package in the startup thread. It is not necessary to call this explicitly in every thread created by the [thread::create] command as the C-code will do that automatically as the first thing. * doc/ttrace.man: Updated example usage to reflect above changes. * lib/ttrace.tcl: Spliced version numbering of the Ttrace package to the version of the Thread package because of the weirdness of the Tcl package loading mechanism. Also, the broadcast script used within the ttrace::eval now explicitly loads Ttrace package in every broadcasted thread. 2006-10-05 Zoran Vasiljevic * generic/threadPool.c: * generic/threadCmd.c: Call Tcl_PkgRequire() in the NewThread() to properly initialize the extension in any new thread. * doc/ttrace.man: Add small example of ttrace usage. * lib/ttrace.tcl: Fixed [ttrace:eval] to not to call [package require Ttrace] in the broadcast script as this is now done implicitly for all new threads. 2006-08-06 Zoran Vasiljevic *** 2.6.4 TAGGED FOR RELEASE (thread-2-6-4) *** * generic/tclXkeylist.c: Silenced various * generic/threadCmd.c compiler warnings. * generic/threadSvCmd.c: * README: Removed version information. * configure.in: Bumped to 2.6.4 version. * confiigure: Regenerated. 2006-06-04 Zoran Vasiljevic * generic/threadSvCmd.c: SvIncrObjCmd() now implicitly creates shared array and/or element and initializes it to zero if the array and/or the element were not found. * generic/tclThread.h: Removed some unusded debugging defs 2006-04-05 Jeff Hobbs * win/vc/pkg.vc (PACKAGE_VERSION): correct to 2.6.3 for MSVC make. 2006-03-28 Jeff Hobbs * generic/threadPoolCmd.c (AppExitHandler): fix teardown to destruct pool list correctly.

Also, fixed exclusive mutex ownership and usage counting. * configure.in: uses TEA 3.5 * tclconfig: updated to TEA3.5 2006-01-28 Zoran Vasiljevic * generic/threadSpCmd.c: Revamped handling because of the deep * generic/threadSpCmd.h: race condition which resulted in * tests/thread.test: deadlocks when using exclusive mutexes. 200i-10-15 Zoran Vasiljevic * generic/threadCmd.c: channel transfer code cleans ready-to-fire events from the thread event queue prior to cutting the channel out of the interp. * tests/thread.test: allows channel transfer tests for all Unices and Windows using Tcl 8.4.10+ core. 2005-09-23 Zoran Vasiljevic * generic/threadCmd.c: ThreadDetach() sets the both source and target thread ID's for the detached channel to zero, thus signalizing the cleanup code to leave the channel in the cleanup-list when the thread who detached it exits. 2005-08-24 Zoran Vasiljevic * generic/tclXkeylist.c: made some calls static so they do not interfere for static linking with certain extensions. 2005-08-08 Zoran Vasiljevic * generic/threadSvCmd.c: fixed traversing the list of registered object types in Sv_DuplicateObj() (thx to eric.melbardis@netkitsolutions.com) 2005-07-27 Zoran Vasiljevic *** 2.6.2 TAGGED FOR RELEASE (thread-2-6-2) *** * configure: regen * unix/README: added some clarifications about usage of --with-gdbm switch * README: * configure.in: bumped version to 2.6.2 * aclocal.m4: fixed for alternate gdbm lib location as per patch request #1245204 * generic/tclThread.c: removed Thread_Unload and Thread_SafeUnload because we can't really be unloaded. * html/thread.html: regen * html/tpool.html: regen * html/tsv.html: regen * html/ttrace.html: regen * man/thread.n: regen * man/tpool.n: regen * man/tsv.n: regen * man/ttrace.n: regen 2005-07-26 Mo DeJong * Makefile.in: Remove SYSTEM_TCLSH and any code that tries to run tclsh at build time aside from running the test cases. * configure: Regen. * configure.in: Remove calls to TEA_BUILD_TCLSH and TEA_BUILD_WISH since these were removed from tcl.m4. This fixes up the build when --with-tcl indicates either a build dir or and install dir. 2005-07-25 Zoran Vasiljevic * pkgIndex.tcl.in: simplified by introducing a helper procedure, thus avoiding too much quoting. 2005-07-24 Mo DeJong * Makefile.in: Subst TCLSH_PROG as SYSTEM_TCLSH and subst BUILD_TCLSH and BUILD_TCLSH_PROG. * configure: Regen. * configure.in: Invoke TEA_BUILD_TCLSH from tcl.m4 to correctly determine BUILD_TCLSH. 2005-04-12 Zoran Vasiljevic * generic/tclThread.h: * generic/threadCmd.c: reverted some changes by the last checkin which slipped in by mistake 2005-04-09 Zoran Vasiljevic * generic/tclThread.h: * generic/threadCmd.c: added Thread_Unload and Thread_SafeUnload to be able to load into the 8.5 shell. Both calls are still no-ops. 2005-03-18 Jeff Hobbs * Makefile.in (AR): use @AR@ (TCLSH_ENV): add TCL_THREAD_LIBRARY var * pkgIndex.tcl.in: grok TCL_THREAD_LIBRARY var * configure, configure.in: update to TEA 3.2 2005-03-15 Zoran Vasiljevic * pkgIndex.tcl.in: Applied patch for Bug #1163357. Also, fixed the case when directory path contains blanks. 2005-03-05 Zoran Vasiljevic * generic/threadSvCmd.c: fixed potential access to the unlocked (and thus eventually freed) container * lib/ttrace.tcl: the overloaded [info] command now does the right thing when applied to non-existing procedures. We now transparently resolve them and then allow the [info] to operate on them. The ttrace::enable can now be called recursively. Also, fixed stript generation issues for namespaced variables containing wild escape sequences. 2005-01-03 Zoran Vasiljevic * generic/threadPoolCmd.c: fixed Tcl Bug #1095370. We were wrongly tearing down workers on idle timer expiry *below* the number of workers set by the "-minworkers" option. * lib/ttrace.tcl: added [ttrace::config] to control some runtime options. The only option it allows now is "-doepochs". This is a boolean flag turning the epoch generation off/on. Also, improved handling of XOTcl introspections in regard to namespaced objects/classes. 2005-01-03 Zoran Vasiljevic * lib/ttrace.tcl: added [ttrace::isenabled] and modified the [ttrace::addtrace] to dynamically activate the tracer if the tracing is already enabled. This way we can dynamically load tracer scripts. 2005-01-03 Zoran Vasiljevic **** RELEASE: 2.6.1 Tagged **** * aolserver.m4: * configure.in: * configure: rebuild and include conditional compilation for AOLserver which was wrongly ommited since the switch to the TEA3 build system. Also, we will now revert to .. version numbers for all releases. * generic/threadCmd.c: added new option "-head" to the [thread::send] command so scripts can be placed on the head of the thread event queue instead of the tail only. * doc: rebuild html/nroff files from doctools sources * generic/threadPoolCmd.c: * generic/threadSvCmd.h: * generic/tclThread.h: removed compat macros for 8.3 core * test/thread.test: added case for [thread::send -head] 2004-12-23 Zoran Vasiljevic **** RELEASE: 2.6 Tagged **** * tcl/cmdsrv/cmdsrv.tcl: example command server listens on loopback interface (127.0.0.1) only * README: removed stuff about (now unsupported) Tcl8.3 core * unix/README: clarified usage of the CONFIG file * win/vc: adjusted MSVC files for changes introduced by TEA3 2004-12-18 Zoran Vasiljevic **** COMPATIBILITY: Dropped support for Tcl8.3 **** * aclocal.m4: Adjusted for TEA3 * Makefile.in: * configure.in: * pkgIndex.tcl.in: * configure: Rebuild with autoconf 2.59 * tests/all.tcl: Removed extra handling for Tcl 8.3 * tests/thread.tcl: since we do not support 8.3 any more * generic/psGdbm.c: * generic/threadCmd.c: * generic/threadSvCmd.c: * doc/thread.man: Updated docs for the 2.6 release * doc/tpool.man: * doc/tsv.man: * doc/ttrace.man: 2004-11-27 Zoran Vasiljevic * generic/threadPoolCmd.c: Fixed race condition which resulted in blocking at pool creation with high -minworkers threads. This fixes the Tcl Bug #933975. 2004-11-25 Zoran Vasiljevic * tests/thread.tcl: Disabled all tests handling channel transfer for Windows ports until core is capable of handling this correctly. * generic/threadSpCmd.c: Fixed segmentation problems observed on Windows ports and related to notification of an uninitialized condition variable(s). This closes Bug #1051068 (wrongly posted under Tcl Patches at SF). * doc/thread.man: Fixed mutex/condvar code example. Thanks to Gustaf Neumann of XOTcl for the tip. 2004-10-21 Andreas Kupries * tests/thread.test: Added two tests checking the working of fileevents after a pipe channel has been transfered. The second has to fail for any core where TIP #218 is not applied, because the incoming alert is directed to the wrong thread for event processing. 2004-10-20 Zoran Vasiljevic * generic/threadCmd.c (ThreadSetResult): adjusted handling of interp result to accomodate for recent changes in Tcl core. This closes Tcl Bug# 1050490. 2004-10-19 Andreas Kupries * generic/threadSvCmd.c: Added a prototype for SvObjDispatchObjCmd. Prevented compilation of debug variant on Windows due to warning as error. * tests/thread.test: Added more tests transfering channels between threads for in-core drivers. 2004-10-18 Andreas Kupries * generic/threadCmd.c (ThreadErrorProc): Added code to explicitly initialize the field 'interp' in ThreadSendData. This was ok (NULL) for a regular build, but when build with symbols the guard pattern forced a crash in test thread-16.2. * tests/thread.test: Duplicate test id thread-16.1 renamed to thread-16.2. 2004-08-14 Zoran Vasiljevic * generic/threadPoolCmd.c: fixed broken parsing of pool handles. Pool handles are now generated in the same format as thread handles. * generic/threadCmd.c: thread handles are now cased to (void*) and sprint/sscanf calls are used to generate thread handles. This concludes the effort of correcting broken handles on 64-bit machines since the problem was actually in Tcl itself, rather than here. 2004-07-21 Zoran Vasiljevic * generic/tclThread.h: corrected namespace prefix for AOLserver 4.x or higher, since namespaced commands are now supported. * generic/threadCmd.c: allows for re-initializing of package commands for AOLserver 4.x (or higheri) interpreters. This way we assure to have correct set of commands even if nobody loaded the package on server startup. Also, thread handles returned by the package now have the form: "tid" in (yet another) attempt to rectify problems found on Cray computers. * generic/threadPoolCmd.c: adjusted handles of the pools to match ones of threads (see above). 2004-07-21 Zoran Vasiljevic * doc/*: reformatted docs and added some clarifications about mutex handling. * generic/threadCmd.c: rewritten handling of thread handles as passed to Tcl. Instead of casting Tcl_ThreadId to unsigned int which brought some problems on Cray machines, we're now generating opaque handles and match them to Tcl_ThreadId internally. NOTE: this is not supposed to be a compatibility issue since thread-handles should have been treated as opaque anyways. * generic/threadSpCmd.*: improved behaviour when destroying locked mutexes and locking the same mutex twice from the same thread. In both cases we throw Tcl error instead of coring the process or deadlocking the (naive) application. * generic/threadSvCmd.*: number of tsv buckets is now compile time constant. * lib/ttrace.tcl: Fixed error in unknown wrapper when the passed command was empty string. * tests/all.tcl * tests/thread.test: rewritten from scratch. * tests/tpool.test: * tests/ttrace.test: * tests/tsv.test: new files, currently no-ops. 2004-01-31 Zoran Vasiljevic * lib/ttrace.tcl: added unconditional "package require" call to ttrace::eval so we need not explicitly load the Ttrace package in each and every thread. Also, fixed some issues with errorInfo/errorCode handling. * pkgIndex.tcl.in: fixed Tcl Bug #918137 * doc/format.tcl: fixed inclusion of man.macros in every *.n doc file 2004-01-31 Zoran Vasiljevic * generic/threadCmd.c: fixed incorrect handling of return codes from the scripts passed to threads. We were wrongly triggering error for non-error return codes such as TCL_RETURN, TCL_BREAK, TCL_CONTINUE etc. Now we trigger error only for TCL_ERROR and return other codes (as-is) to the caller. This also fixes the Tcl Bug #884549. 2003-12-22 Zoran Vasiljevic * generic/threadSpCmd.c: added recursive and reader/writer locks and associated commands * generic/threadSpCmd.h: added new file * generic/lib/ttrace.tcl: added Ttrace package implementation * doc: added documentation for Ttrace package and synced other doc files to match the release 2.6 state. 2003-12-01 Zoran Vasiljevic * generic/threadCmd.c: removed the concept of foreign thread since it broke our async message bouncing. We still have to find the way how we should avoid broadcasting non-package threads (like for aolserver). 2003-11-27 Zoran Vasiljevic * generic/threadCmd.c: fixed mutex release in ThreadSend when refusing to send message to foreign thread. Also, clear the result of the thread::broadcast since it should not return anything to the caller, no matter the outcome of the command. 2003-11-27 Zoran Vasiljevic * generic/threadCmd.c: mark threads created by the package to distinguish them from "foreign" threads. We will forbid sending messages to those since they will probably never listen. * generic/threadSvCmd.c: corrected some typos * generic/threadSvListCmd.c: added implementation for the "tsv::lset" command * generic/threadPoolCmd.c: added optional varname argument (last arg) to the tpool::cancel 2003-11-25 Zoran Vasiljevic * doc/format.tcl: new file with a simple poor man's documentation formatter. * doc/thread.man * doc/tpool.man * doc/tsv.man: new doctools source files for building the package documentation. * Makefile.in: added support for building nroff and html files out of doctools sources found in doc directory. 2003-11-18 Zoran Vasiljevic * generic/threadCmd.c: added implementation of the thread::broadcast command. This one asynchronously sends a script to all known threads, except the caller. 2003-09-03 Zoran Vasiljevic * generic/tclXkeylist.(c|h): added keyed-list datatype implementation borrowed from the TclX package. This is now part of the shared variable command set. * generic/threadSvCmd.(c|h): modified to support persistent shared variables with plugin-architecture for different persistent store implementations. * generic/threadSvlistCmd.(c|h): modified to reflect added support for persistent shared variables. * generic/psGdbm.(c|h): added persistent store wrapper for the GNU gdbm package. * configure et al: regenerated with autoconf because of added optional comilation with GNU gdbm. Updated makefiles to process newly added files for keyed lists and persistent stores. 2003-08-27 Zoran Vasiljevic * generic/threadPoolCmd.c: after expiration of the idle timer, all idle workers exit unconditionaly. Before the change, idle threads exited after getting the first job posted. This way we were loosing work. 2003-08-26 Zoran Vasiljevic * generic/threadPoolCmd.c: fixed result list corruption in TpoolCancelObjCmd. 2003-07-27 Zoran Vasiljevic * generic/threadPoolCmd.c: added "-nowait" option to the "tpool::post" commandi. This allows the caller to post jobs to the threadpool queue without waiting for an idle thread. The implementation will start at least one worker thread if there is none available to satisfy the first request. Added "tpool::cancel" command. See docs for info. 2003-05-31 Zoran Vasiljevic * generic/threadCmd.c: fixed ListRemoveInner for the Tcl Bug #746352 * generic/threadSpCmd.c: modified Sp_Init to return a proper value for Tcl Bug #746352 2003-05-17 Zoran Vasiljevic * generic/threadCmd.c: sets the name of the new thread to "-tclthread-" when compiled for AOLserver 2003-04-29 Zoran Vasiljevic Tagged interim 2.5.2 release. * configure.in * configure: Added quick fix for autoconf issues related to $srcdir and building of the package from the top-level dir instead of unix/win subdir. Thanks to Mo DeJong for the fix. 2003-04-10 Zoran Vasiljevic * generic/threadCmd.c: removed checking of stopped flag during walk of the list of active threads. This solves some subtle thread reservation problems with threads marked to unwind on error. Also, added new "-errorstate" configuration option to set/get error state of reserved unwinding thread. 2003-04-02 Zoran Vasiljevic * generic/threadCmd.c: * generic/threadPoolCmd.c: * generic/threadSpCmd.c: * generic/threadSvCmd.c: always call registered exit callbacks with non-NULL clientData, otherwise Tcl won't invoke the registered callback. 2003-03-28 Zoran Vasiljevic * generic/threadSvList.c * generic/threadSvCmd.c: fixed some rare cases where we incorrectly deep-copied the list object having zero elements. * generic/threadCmd.c: fixed broken AOLserver 3.x compatibility mode introduced by last 4.x changes. 2003-03-17 Zoran Vasiljevic * generic/threadSvCmd.c: fixed incompatibility with Tcl 8.4.2 filepath object * generic/threadCmd.c: * aolstub.cpp: adjusted for AOLserver 4.0 2003-02-24 Zoran Vasiljevic * generic/threadCmd.c: fixed ThreadSetResult to correctly initialize all elements of the result structure. 2003-02-08 Zoran Vasiljevic * generic/threadCmd.c: fixed ListRemoveInner to correctly update global threadList ptr when the last referenced thread exits. This was not the case before and we were trashing memory leading to process exitus. 2003-01-25 Mo DeJong * generic/threadCmd.c (ThreadSendObjCmd): The thread::send command was not working under Win32 because threads that had an id that was a negative number were generating a usage error in the thread::send command. * tests/thread.test: Add test for negative number as thread id. 2003-01-22 Zoran Vasiljevic * generic/threadCmd.c: fixed reference to errorInfo when reporting error from the passed script. 2003-01-21 Mo DeJong * configure: Regenerate to include recent fixes for mingw build support in tclconfig module. 2002-12-18 Zoran Vasiljevic * README: added some AOLserver info * tcl/tpool/tpool.tcl: added missing tpool::names command 2002-12-14 Zoran Vasiljevic * doc/*: finished docs for the 2.5 release 2002-12-09 Zoran Vasiljevic * generic/threadPoolCmd.c: added tpool::names command added -exitscript for tpool::create * doc/tpool.tmml * doc/man/tpool.n * doc/html/tpool.html: added files. This is still the work in progress. 2002-12-06 Zoran Vasiljevic * configure.in * configure * Makefile.in * aolserver.m4: added support for compilation under AOLserver as loadable module. 2002-12-06 Zoran Vasiljevic * generic/threadSvCmd.c: the tsv::lock now allows for unsetting the shared array within the script argument. * generic/threadPoolCmd.c: fixed one missing mutex unlock in the ThreadRelease. * tcl/tpool/tpool.tcl: implemented missing API calls found in the C-level implementation. * tcl/phttpd/phttpd.tcl: simplified switching to Tcl-level threadpool implementation. 2002-12-04 Zoran Vasiljevic * generic/threadPoolcmd.c: rewritten to use worker threads sitting on the cond var instead of in the event loop. The poster thread still respects i.e. does not block the event loop while posting jobs. 2002-12-03 Zoran Vasiljevic * generic/tclthread.h: added SpliceIn/SpliceOut macros. Fixed to include exports from threadPoolCmd.c * generic/threadSpCmd.c: does regular namespace handling over the NS variable instead of hard-coding the "thread" prefix for mutex/cond commands. * generic/threadCmd.c: rewritten to use SpliceIn/SpliceOut macros instead of hand-fiddling with linked lists. * generic/threadPoolCmd.c: new file * Makefile.in: added threadPoolCmd.c to list of source files. 2002-11-25 Zoran Vasiljevic * tcl/phttpd/phttpd.tcl: added raw file; no thread support * tcl/cmdsrv/cmdsrv.tcl: first working version 2002-11-24 Zoran Vasiljevic * tcl/tpool/tpool.tcl: added threadpool implementation in Tcl * tcl/phttpd: added directory for later mt-enabled pico-httpd * tcl/cmdsrv: added directory for later socket command server * doc/man/thread.n * doc/thread.tmml * doc/html/thread.html: new tsv::eval, thread::attach, thread::detach * generic/threadSvCmd.h * generic/threadSvCmd.c: added tsv::eval command * generic/threadCmd.c: added thread::attach, thread::detach Also, fixed thread::preserve and thread::release to accept the thread id as the optional paramter. 2002-11-23 Zoran Vasiljevic * generic/threadCmd.c: fixed ListRemoveInner() to recognize and ignore already removed tsd thread structures. Fixed some invalid TCL_OK returns which masked serious errors. 2002-11-07 Zoran Vasiljevic * generic/threadCmd.c: fixes problem when trying to report the error from an async callback when the stderr channel is not available (wish/tclkit on windows). Thanks to Wojciech Kocjan for the correction. 2002-10-23 Zoran Vasiljevic * generic/threadCmd.c: added handling of background errors while doing an async callback. 2002-10-20 Zoran Vasiljevic * doc/html/thread.html * doc/man/thread.n * doc/thread.tmml: fixed "thread::send" command summary. It was showing the wrong position of the "-async" argument. * generic/threadSpCmd.c: adjusted mutex/cond handles to use the same format and handling as AOLserver counterparts when compiled for AOLserver support. This way one can mix and match primitives declared with ns_mutex and thread::mutex and/or ns_event and thread::cond commands. Added thread::eval command. See documentation for syntax and usage. 2002-10-15 Jeff Hobbs * configure: * configure.in: move the CFLAGS definition into TEA_ENABLE_SHARED and make it pick up the env CFLAGS at configure time. 2002-08-23 Zoran Vasiljevic * threadCmd.c: fixed potential memory corruption when releasing preserved interpreter. [Tcl bug 599290] 2002-08-19 Zoran Vasiljevic * generic/threadSvCmd.c: we now properly invalidate duped object string rep if the internal rep has been regenerated. 2002-08-18 Zoran Vasiljevic * generic/threadCmd.c: updated some comments * generic/threadSvCmd.c: * generic/threadSvListCmd.c: fixed silly mem leak where we were registering commands and object types for each new thread, resulting in unnecessary table grow. Not a memory leak per-se, therefore not found by Purify, but shows itself by observing the size of the process using the top utility. Gosh! 2002-08-03 Zoran Vasiljevic * generic/threadSvListCmd.c: corrected "tsv::lpush" to correctly make a copy of the object pushed into the list in shared array element. 2002-07-22 Mo DeJong * README: Fix typo. * doc/man/thread.n: Note that thread::join and thread::transfer are only available with Tcl 8.4. 2002-07-20 Mo DeJong * generic/threadSvCmd.c (Sv_tclEmptyStringRep, Sv_Init): Avoid linking to the tclEmptyStringRep variable defined in Tcl since this makes it very difficult to load the Thread package into an executable that has also loaded Tcl. The previous approach used a hack under Windows, we now use this same hack on all systems. [Tcl patch 584123] 2002-07-19 Zoran Vasiljevic * threadCmd.c: added some macros to simplify adding and removing result structure in and out of the corresponding lists 2002-07-18 Zoran Vasiljevic * threadCmd.c: modified thread::release to allow for optional "-wait" argument. This will result in the thread waiting until the target thread has really exited. Otherwise, the command exits immediately and target thread may exit asynchronously some time later. This is not techically needed since one can always join the exiting thread, but the join command is not available for some older Tcl versions. 2002-07-13 Zoran Vasiljevic * doc/man: * doc/html: added two directories with TMML generated files * doc/thread.tmml: fixed for the final 2.4 release * Makefile.in: updated install-doc target to look for man files under doc/man instead only under doc directory 2002-07-12 Zoran Vasiljevic * generic/threadSvCmd.s: fixed handling of string rep in shared var object duplicator 2002-07-09 Zoran Vasiljevic * README: added this file * license.terms: added this file 2002-07-05 Zoran Vasiljevic * tclconfig/tcl.m4: fixed reference to MINGW so we can compile w/o MSVC under windows. 2002-07-03 Zoran Vasiljevic * generic/threadSvCmd.c: simplified object duplicator 2002-06-17 Zoran Vasiljevic * generic/threadCmd.c: cleanup of some unused variables * generic/threadSvCmd.c: * generic/ThreadSpCmd.c: * generic/threadSvList.c: added CONST qualifiers to avoid warnings when compiling against 8.4 core. 2002-05-25 Zoran Vasiljevic * generic/threadCmd.c: added some typecasts to satisfy Windows * generic/threadSvCmd.h: added some typecasts to satisfy Windows 2002-05-04 Zoran Vasiljevic * generic/threadSvCmd.c: removed errant reference to (still not) supported shared dictionary and shared keylist datatypes. 2002-04-27 Zoran Vasiljevic * generic/threadCmd.c: fixed processing of -eventmark. We now properly wait for target thread to catch up with processing events. 2002-04-07 Zoran Vasiljevic * generic/threadCmd.c: added call to Ns_TclMarkForDelete(interp) when compiled for AOLserver support, otherwise we were leaking std channels on thread exit. 2002-04-03 Jeff Hobbs * Makefile.in: improved use of DESTDIR in install targets. Removed need for installdirs target. Broke TCLSH_PROG into TCLSH_ENV and TCLSH_PROG with TCLSH var and added comments about TCLSH_ENV. Added default shell and gdb targets. * configure: * configure.in: updated to new TEA base that: prefixes all macros with TEA_* instead of SC_*; adds TEA_PREFIX, which defaults the prefix and exec_prefix values to what Tcl used; adds TEA_SETUP_COMPILER, which handles basic compiler / support program checks and simplifies the configure.in. Turn on --enable-threads by default and do sanity checking as well. 2002-04-01 Jeff Hobbs * Makefile.in (install-lib-binaries): ensure that binary files are installed with executable bit set (use INSTALL_PROGRAM) 2002-03-28 Jeff Hobbs * configure: * configure.in: BUILD_${PACKAGE} had to be static BUILD_thread in AC_DEFINE because autoconf wasn't substituting ${PACKAGE}. 2002-03-27 Jeff Hobbs * Makefile.in (TCLSH_PROG): moved and updated env var definitions to have tclsh work from build dir. Removed TCL_EXTRA_CFLAGS, TCL_LD_FLAGS, TCL_SHLIB_LD_LIBS, TCL_DBGX, TCL_STUB_LIB_FILE, TCL_STUB_LIB_SPEC as they aren't needed (configure acquires all that info for us). TCL_LIBS is also not needed, but left in as a reference to the libs Tcl used. * configure: regen based on updated tclconfig/tcl.m4 * configure.in: moved the SHLIB_LD_LIBS magic into tclconfig/tcl.m4 and noted where users can modify (SHLIB_LD_)LIBS. 2002-03-19 Jeff Hobbs * generic/tclThread.h: * generic/threadCmd.c: added stub voodoo magic to allow building against Tcl 8.3 and still get all the 8.4+ functionality when later loaded into an 8.4+ interp. * pkgIndex.tcl.in: simplified auto-generated pkgIndex.tcl file. * tests/all.tcl: * tests/thread.test: improved to detect 8.3/8.4 pkg differences * tclconfig/tcl.m4,install-sh (new): * config/* (removed): * aclocal.m4: * configure: * configure.in: * Makefile.in: Updated build system to use tclconfig (TEA 2002) structure. 2002-03-09 Zoran Vasiljevic * generic/threadSvCmd.c: fixed memory leak when copying objects using custom object duplicator. If a duplicator was registered more than once, we were leaking memory. 2002-03-08 Zoran Vasiljevic * generic/threadCmd.c: added thread::configure -unwindonerror configuration option. See docs for usage. * doc/thread.n: added docs for thread::configure -unwindonerror 2002-03-07 Zoran Vasiljevic * generic/threadSvCmd.c: tsv::names will skip reporting shared arrays with leading dot in their names. This is turned-on only for AOLserver builds with the HIDE_DOTNAMES. For the regular Tcl builds, all arrays are reported, regardless of the name. Motivation behind this feature is to allow certain data privacy. It is not name-clash proof, though. 2002-02-12 Zoran Vasiljevic * generic/threadCmd.c: fixed thread::preserve glitch. We never actually did bump the reservation counter by a silly mistake. 2002-02-12 Zoran Vasiljevic * generic/threadCmd.c: added thread::preserve and thread::release commands. These allow for a simple reference counting when creating and/or tearing-down threads. Instead of calling thread::unwind in the target thread, one can use "thread::release id" to dispose it. This is much easier to use and it can be coupled with calls to thread::preserve to implement simple thread reservation mechanism. * doc/thread.n: added docs for thread::preserve/thread::release 2002-02-09 Zoran Vasiljevic * generic/threadCmd.c: added thread::configure interface. Currently only "-eventmark" option is supported. Allows for AOLserver builds to change the "thread::" prefix by re-defining the "NS" compile-time constant. * doc/thread.n: added docs for thread::configure 2002-02-06 Zoran Vasiljevic * generic/aolserv.cpp: (new) added for loading into the AOLserver. Still needs to fix the Makefile and friends to get it up and running. * generic/threadCmd.c: added conditional setup of the command prefix. Now, the "NS" can be used to select the command prefix for thread::* commands. 2002-01-26 David Gravereaux * generic/threadSvCmd.c: A small 'const' qualifier change to remove a warning. It's a bit more wordy now, but reads a little clearer to me. Unscambling pointer math gives me a headache and combined with a cast tends to get dangerous. * win/threadWin.c: new idea for thread::kill added. It's wrapped in an #if 0/#endif for now. I do notice that tcl.h is now typedef'ing ClientData as an 'int *'. It used to 'void *', didn't it?? The ISO/ANSI/CLEAN C style of setting a typed pointer to a void* now doesn't want to work. Maybe I do too much C++ to have noticed this before... 2002-01-23 Zoran Vasiljevic * generic/threadCmd.c: fixed address of the target interpreter when doing the callback async script processing. All messages went to the main interpreter instead of the selected interpreter, causing process to hung when posting callbacks to more that one interp at the same time. (thanks Jean-Luc Fontaine for the tip) 2002-01-20 Zoran Vasiljevic * generic/threadCmd.c: fixed multiple async reporting of error events (thanks Jean-Luc Fontaine for the tip) 2002-01-02 Zoran Vasiljevic * generic/threadSvListCmd.* (new): added for the new implementation of the thread-shared-variable (tsv) interface. * generic/threadSvCmd.c: now uses shared Tcl objects instead of strings for storing data in shared arrays. This improves performance on large shared data structures. Added new tsv::* syntax, per request. This replaces older thread::sv_* interface. Older commands are still present but will be removed as soon we hit the 3.0 version. * generic/threadCmd.c: revamped to support asynchronous backfiring of scripts so we can vwait on the results of thread processing. This also corrected the bug #464340. Affected command is thread::send. * doc/thread.n: added docs for all thread::* and tsv::* commands. This fixes #416850 bug report. The html/tmml files are still out of date. * configure: built with autoconf 2.52 * config/config.guess (new): needed for the new configure * config/config.sub (new): needed for the new configure * Makefile.in: added lines for new generic/threadSvListCmd.c * configure.in: moving to 2.4 version. * unix/threadUnix.c: removed traces of ThreadKill. It is still not clear wether we should implement this functionality or not. * win/threadWin.c: see above. * pkgIndex.tcl.in: fixed to correctly handle version for different Tcl core versions. 2001-09-05 David Gravereaux * generic/*: * win/threadWin.c (new): updated for a new threadWin.c and finished replacing use of thread.h with tclThread.h. threadWin.c is an experiment to add a 'thread::kill' command. Not done yet. * win/vc/thread.rc (removed): * win/thread.rc (new): moved it up a directory. 2001-09-04 David Gravereaux * generic/thread.h (deleted): * generic/tclThread.h (new): * generic/threadCmd.c: decided to change the name of 'thread.h' to 'tclThread.h', per request. * generic/thread.h: * generic/threadCmd.c: Re-added original implimentation of [thread::exit]. for `emergency use only`. You have been warned ;) * configure.in: * configure: * win/vc/thread.dsp: * win/vc/pkg.vc: Upped version numbers to 2.3 and 2.1.3 because I just cut a release. 2001-09-04 David Gravereaux -=[ Official 2.2 Tagged and cut. ]=- 2001-05-27 David Gravereaux * tests/thread.test: fixed small typo in comments. 2001-08-03 Jeff Hobbs * Makefile.in: corrected handling of VERSION * generic/threadCmd.c: * generic/thread.h: added Thread_SafeInit * win/vc/makefile.vc: added -DBUILD_thread to cflags. 2001-05-27 David Gravereaux * configure: * configure.in: * Makefile.in: Added package versions to the compile flags. [bug #421246] 2001-04-28 David Gravereaux * generic/threadCmd.c (NewThread): removed the previous addition of Tcl_FinalizeThread. Tcl_ExitThread calls it anyways (my mistake). The resource leak was in the core. See -> http://sourceforge.net/tracker/?func=detail&atid=110894&aid=419683&group_id=10894 for the fix. That patch is pending approval. To acheive the same behavior of emptying the event loop the way thread::wait used to work, use the following: set T [thread::create {thread::wait; update}] thread::send -async $T thread::unwind * generic/thread.h: * win/vc/makefile.vc: * win/vc/thread.rc: * win/vc/pkg.vc (new): Moved version numbers from the header file. It isn't an export API or anything. Moved version numbers to the build files. I'll modify configure.in and makefile.in a little later. 2001-04-26 David Gravereaux * config/* (new): old site-wide config directory re-added. * generic/threadCmd.c (ThreadEventProc): ThreadErrorProc now supported in asyncronous sends when Tcl_Eval returns other than TCL_OK. Errors were silently ignored prior to this. Bug #219324 ==== INTERFACE CHANGE ==== * generic/threadCmd.c: * generic/thread.h: thread::exit renamed to thread::unwind. The name of 'exit' is misleading. An exit implies an unconditional return. But there are conditions. 'unwind' describes with more clarity what's happening to the prior thread::wait. For example: # parent thread set T [thread::create {source worker.tcl}] .... thread::send -async $T doStuff .... thread::send -async $T doStuff .... thread::send -async $T thread::unwind # worker.tcl proc init {} {#do initialization} proc cleanup {} {#do cleanup} proc doStuff {} {#the work} init thread::wait cleanup When worker.tcl is sourced, the execution stops at thread::wait and the event loop is entered. When thread::unwind is sent to the worker, thread::wait falls-out and cleanup is called. The condition for thread::unwind to cause an exit is determined by the script. If thread::wait was the last Tcl command in the script, yes the thread will exit. But if thread::wait is not the last, the execution of the script is just continued. Hence, the name change to clarify this fact. Package version has not been changed. There hasn't been an official release of 2.2, so it stays. * doc/thread.n: * tests/thread.test: Replaced thread::exit with thread::unwind and documented the change and clarified the subtleties. * win/vc/makefile.vc: * win/vc/thread.dsp: Changed NODEBUG macro to be DEBUG instead. Double negatives give me a headache. DEBUG=1 makes more sense to me than NODEBUG=0. Not that I didn't think you wouldn't have disagreed it was confusing, no? * win/vc/config.vc: Added a reminder to edit before using. * win/vc/thread.rc: Added authors and removed the Ajuba branding. 2001-04-25 David Gravereaux * generic/threadCmd.c (ThreadWait)(NewThread): Removed the event loop sinking which was probably done because Tcl_FinalizeThread was missing from NewThread(). Now the event loop is cleaned by Tcl_FinalizeThread and ThreadWait doesn't manipulate events that don't belong to it. Bug #418689 and #418693 * generic/threadCmd.c (Thread_Init): logic fix in a version check for determining the 8.3 package subset. 2000-11-02 David Gravereaux * generic/threadCmd.c (NewThread): Added logic to test for a working Tcl_Init() based on the core version at runtime and ignore its failure in versions 8.3.[1,2] and 8.4a1. [BUG: 5301] 2000-10-26 David Gravereaux * generic/thread.h: * win/vc/config.vc: * win/vc/makefile.vc: * win/vc/thread.dsp: upped version numbers to 2.2 along with adding a new macro (THREAD_VERSION_SUBSET83) defining the version when loaded into an 8.3 core. Which happens to be "2.1.1" at this time. * generic/threadCmd.c (Thread_Init): Added logic to allow setting the package version at runtime to "2.2" when compiled against 8.4 and loaded into 8.4. When compiled against 8.4, yet loaded into 8.3, thread::join and thread::transfer are not added to the interp and the package version is set to "2.1.1" instead from the single binary. [ie. multiple interfaces in one binary] When compiled against 8.3, thread::join and thread::transfer are non-existant and the package version is always "2.1.1" to maintain a consistent interface in all combinations (as per discussions with Don Porter). 2000-10-16 Zoran Vasiljevic * generic/threadSvCmd.c ThreadSvUnsetObjCmd(): deadlocked. Forgot to release shared-array lock which resulted in deadlock after first successful unset of the variable. 2000-08-29 David Gravereaux * generic/threadCmd.c (NewThread): Tcl_Init return value wasn't being verified. Added a check and failure logic to fall-out. [Bug: 5301] 2000-08-28 David Gravereaux * generic/threadCmds.c (Thread_Init): Added logic to enable thread::join and thread::transfer when loaded into an 8.4+ core. We don't want a seg fault when the Stubs tables don't match for the functions that don't exist in an 8.3 core. 2000-08-23 Brent Welch * configure.in: * win/vc/makefile.vc: Changed to version 2.1 * generic/threadCmds.c: Made the code that uses new Tcl 8.4 APIs conditional using #ifdef. Tested with 8.3.2 * Applied thread-2-1 tag for use with tclhttpd bundled release. 2000-08-21 David Gravereaux * win/vc/makefile.vc: * win/vc/thread.rc: added version numbers to filename to follow Tcl standards. * doc/thread.tmml(new): Initial TMML document. 2000-08-20 David Gravereaux * win/vc/config.vc: * win/vc/makefile.vc: * win/vc/README.txt: * win/vc/thread.dsp: A near top down rewrite that adds four more build configurations. See README.TXT for the details. * win/vc/.cvsignore: A few more glob patterns added to match the new build directories. 2000-08-09 David Gravereaux * win/vc/thread.rc: swapped "Scriptics Corp" for "Ajuba Solutions" * win/vc/config.vc: * win/vc/makefile.vc: cleaned-up old cruft. Added new files from Zoran's patches. made swapping to MSDev 6.0 easier. Removed the '!if $(_NMAKE_VER) > 162' test for 2 reasons. 1) batchmode inference rules are valid since MSDev 5.0 and the core can't be built with less. So don't bother testing. 2) nmake.exe that comes with MSDev 6.0 has a bug with the meaning of that macro and MS decided to use a string instead breaking the integer comparison test. Also added vcvars32.bat to a new setup rule and got config.vc much smaller. * win/vc/thread.dsp: Added new files from Zoran's patch. * win/.cvsignore(deleted): * win/vc/.cvsignore(added): moved file to help keep a cleaner build environment. * generic/threadSvCmd.c: Added some additional casting of Tcl_GetHashValue to prevent compiler warnings. * generic/threadCmd.c(ThreadWait): Removed the event loop sinking after the "while(..) Tcl_DoOneEvent();" because this extension is only responsible for it's own events in the event loop. Any other extension that's queueing events must be responsible for it's own cleanup and should be aware of when the interp (ie. this thread) is going away when we fall-out to Tcl_DeleteInterp from the Tcl_Eval in NewThread(). If other extensions (like Tk) don't become aware, then they need to add a Tcl_CallWhenDeleted handler. 2000-07-14 Zoran Vasiljevic * generic/threadCmd.c: improved thread::exit behaviour now does a better job of draining the event loop before exit. may have some wishes open, though - see ThreadWait(). * generic/threadSpCmd.c, generic/threadSvCmd.c: added some comments in function headers. docs/tests for above still pending. 2000-07-03 Zoran Vasiljevic Summary of changes: * generic/threadSpCmd.c: new file with implementation of "thread::mutex" and "thread::cond" commands. Documentation and tests are still pending. * generic/threadSvCmd.c: new file with implementation of "thread::sv_*" family of commands modeled after AOLserver nsv_* ones. Documentation and tests are still pending. * Makefile.in: fixed for the two above * doc/thread.html * doc/thread.n: added 'thread::exists' docs * generic/thread.h added declarations for new commands (above) * generic/threadCmd.c: Added "thread::exists" command. Moved most of internal functions in threadCmd.c to statics, except the Thread*ObjCmd(). Changed behaviour of "thread::exit". It now simply flips the bit to signal thread stuck in thread::wait to gracefuly exit. Consequence: command now does not trigger error on thread exit. Also, thread event queue is now properly cleared. ThreadWait() and ThreadStop() are newly added to support this. Also the ThreadSpecificData has one more integer: "stopped" Replaced ref's to obsolete Tcl_GlobalEval() with Tcl_EvalEx(). Fixed broken 'thread::create -joinable script'; was missing initialization of script variable Added calls to initialize new commands in threadSpCmd.c and threadSvCmd.c files. 2000-05-18 Brent Welch * Restored Andreas' changes for transferring sockets. 2000-05-16 Brent Welch * Temprarily rolled back Andreas' changes so I can fix up the 2.0 release (configure and Make). Also need to apply a 2.0 tag. 2000-05-09 Andreas Kupries * tests/thread.test: Removed dependency on aclocals.m4. Using a real temporary file now, as created by a call to tcltest::makeFile. Updated test 6.3 to use the correct length information. 2000-05-04 Andreas Kupries * Overall changes: (1) Added joinable threads. (2) Added transfer of channels between threads. * generic/threadCmd.c: Added functions Thread_Join and ThreadJoinObjCmd. Extended function ThreadCreateObjCmd to handle a -joinable flag. Fixed bug in Thread_Create, the argument 'stacksize' was not used. Removed declaration of ThreadObjCmd, which was not used anywhere else in the code. Added functions Thread_Transfer, ThreadTransferEventProc and ThreadTransferObjCmd. Extended behaviour of ThreadDeleteEvent and ThreadExitProc to deal with the new class of events. Changed usage of ckfree to the more canonical Tcl_Free. Same for ckalloc and Tcl_Alloc. * Makefile.in: Fixed bug with regard to the installation of documentation. * doc/thread.*: Added documentation of create -joinable, thread::join and thread::transfer. * tests/thread.test: Added tests for joining of threads and moving channels between threads. 2000-04-19 Brent Welch * win/vc/config.rc, Makefile.vc: Fixes from David Gravereaux 2000-04-18 Brent Welch * Makefile.in: Fixes for make install 2000-04-17 Brent Welch * generic/threadCmd.c Added Tcl_CreateThreadType and TCL_RETURN_THREAD_TYPE macros for declaring the NewThread callback proc. 2000-04-11 Brent Welch * Picked up minor changes from David Gravereaux * for compilation on windows with his alternate project files. 2000-04-10 Brent Welch * Moved all the configure.in, Makefile.in etc. up to the top level out * of the unix (and win) subdirectories. These are now shared. * If you are using CVS, you'll want to get the "config" module into * this directory, or do the checkout of thread again so the config * module is brought in. You should have a "config" subdirectory of * your main thread workspace directory. 2000-04-09 Brent Welch * Updated to compile against 8.3.1 export thread APIs * Added Windows makefiles 2000-03-27 Brent Welch (proxy for Andreas Kupries) * tests/all.tcl: Added this file * tests/thread.test: fixed to use tcltest * doc/thread.n: Added this file as clone of thread.html # doc/thread.html: fixed typo thread2.8.0/win/0000755003604700454610000000000012744437564012123 5ustar dgp771divthread2.8.0/win/makefile.vc0000644003604700454610000004005712744437564014240 0ustar dgp771div#------------------------------------------------------------- -*- makefile -*- # makefile.vc -- # # Microsoft Visual C++ makefile for use with nmake.exe v1.62+ (VC++ 5.0+) # # See the file "license.terms" for information on usage and redistribution # of this file, and for a DISCLAIMER OF ALL WARRANTIES. # # Copyright (c) 1995-1996 Sun Microsystems, Inc. # Copyright (c) 1998-2000 Ajuba Solutions. # Copyright (c) 2001-2005 ActiveState Corporation. # Copyright (c) 2001-2004 David Gravereaux. # Copyright (c) 2003-2008 Pat Thoyts. #------------------------------------------------------------------------------ # Check to see we are configured to build with MSVC (MSDEVDIR, MSVCDIR or # VCINSTALLDIR) or with the MS Platform SDK (MSSDK or WindowsSDKDir) !if !defined(MSDEVDIR) && !defined(MSVCDIR) && !defined(VCINSTALLDIR) && !defined(MSSDK) && !defined(WINDOWSSDKDIR) MSG = ^ You need to run vcvars32.bat from Developer Studio or setenv.bat from the^ Platform SDK first to setup the environment.

This is used as a check to see if vcvars32.bat had been # run prior to running nmake or during the installation of Microsoft # Visual C++, MSVCDir had been set globally and the PATH adjusted. # Either way is valid. # # You'll need to run vcvars32.bat contained in the MsDev's vc(98)/bin # directory to setup the proper environment, if needed, for your # current setup.

Building the Tcl thread extension for Windows ================================================ Thread extension supports two build options: o. MinGW builds: ---------------- The extension can be compiled under Windows using the MinGW (http://www.mingw.org) environment. You can also download the ready-to-go copy of the MinGW from the same place you've downloaded this extension. You should compile the Tcl core with MinGW first. After that, you can compile the extension by running the configure/make from this directory. You can also use the CONFIG script to do this. You might want to edit the script to match your environment and then just do: sh CONFIG This should go smoothly, once you got Tcl core compiled ok. o. Microsoft MSVC++ build: -------------------------- Files in this directory may be useful if you have not set up your TEA (i.e., MinGW) environment and you're using the MSVC++ from Micro$oft. To build the extension invoke the following command: nmake -f makefile.vc TCLDIR= You would need to give the of the Tcl distribution where tcl.h and other needed Tcl files are located. Please look into the makefile.vc file for more information. Alternatively, you can open the extension workspace and project files (thread_win.dsw and thread_win.dsp) from within the MSVC++ and press the F7 key to build the extension under the control of the MSVC IDE. II. Building optional support libraries ======================================= As of 2.6 release, this extension supports persistent shared variables. To use this functionality, you might need to download and compile some other supporting libraries. Currently, there is a simple implementation of shared variable persistency built atop of popular GNU Gdbm package. You can obtain the latest version of the Gdbm from: http://www.gnu.org/software/gdbm/gdbm.html. For the impatient, there are Windows ports of GNU Gdbm found on various places on the Internet. The easiest way to start is to go to the GnuWin32 project: http://sourceforge.net/projects/gnuwin32 and fetch yourself a compiled GNU Gdbm DLL. -EOF- thread2.8.0/win/thread.rc0000644003604700454610000000256412744437564013727 0ustar dgp771div// Version resource script // #include #define RESOURCE_INCLUDED #include LANGUAGE 0x9, 0x1 /* LANG_ENGLISH, SUBLANG_DEFAULT */ VS_VERSION_INFO VERSIONINFO FILEVERSION PACKAGE_MAJOR,PACKAGE_MINOR,0,0 PRODUCTVERSION PACKAGE_MAJOR,PACKAGE_MINOR,0,0 FILEFLAGSMASK 0x3fL #if DEBUG FILEFLAGS 0x1L #else FILEFLAGS 0x0L #endif FILEOS 0x4 /* VOS__WINDOWS32 */ FILETYPE 0x2 /* VFT_DLL */ FILESUBTYPE 0x0L BEGIN BLOCK "StringFileInfo" BEGIN BLOCK "040904b0" /* LANG_ENGLISH/SUBLANG_ENGLISH_US, Unicode CP */ BEGIN VALUE "FileDescription", "Threading extension library for Tcl\0" #if DEBUG VALUE "OriginalFilename", "thread" STRINGIFY(JOIN(PACKAGE_MAJOR,PACKAGE_MINOR)) "d.dll\0" #else VALUE "OriginalFilename", "thread" STRINGIFY(JOIN(PACKAGE_MAJOR,PACKAGE_MINOR)) ".dll\0" #endif VALUE "CompanyName", "NONE!

Currently, following packages are supplied: tpool/ Example Tcl-only implementation of thread pools. The threading extension includes an efficient threadpool implementation in C. This file is provided as a fully functional example on how this functionality could be implemented in Tcl alone. phttpd/ MT-enabled httpd server. It uses threadpool to distribute incoming requests among several worker threads in the threadpool. This way blocking requests may be handled much better, w/o halting the event loop of the main responder thread. In this directory you will also find the uhttpd. This is the same web-server but operating in the event-loop mode alone, no threadpool support. This is good for comparison purposes. cmdsrv/ Socket command-line server. Each new connection gets new thread, thus allowing multiple outstanding blocking calls without halting the event loop. To play around with above packages, change to the corresponding directory and source files in the Tcl8.4 (or later) Tcl shell. Be sure to have the latest Tcl threading extension installed in your package path. - EOF thread2.8.0/tests/0000755003604700454610000000000012744437564012470 5ustar dgp771divthread2.8.0/tests/French.txt0000644003604700454610000025303012726254163014431 0ustar dgp771div########################################################################### #Copyright 1999 The Internet Dictionary Project/Tyler Chambers #http://www.june29.com/IDP/ #This file is free to use and modify.

You can use this extension to gain script-level access to Tcl threading capabilities. The extension can be used with Tcl cores starting from Tcl8.4 and later. Also, this extension supports, i.e. can be used as a loadable module of, AOLserver 4.x series of the highly-scalable web server from America Online. You need to have your Tcl core compiled with "--enable-threads" in order to turn on internal directives supporting thread-specific details of the Tcl API. The extension will not load in an Tcl shell built w/o thread support. This extension is a freely available open source package. You can do virtually anything you like with it, such as modifying it, redistributing it, and selling it either in whole or in part. See the "license.terms" file in the top-level distribution directory for complete information. HOW TO COMPILE ? ================ Only Unix-like and Windows platforms are supported at the moment. Depending on your platform (Unix-like or Windows) go to the appropriate directory (unix or win) and start with the README file. Macintosh platform is supported with the Mac OS X only. The Mac OS 9 (and previous) are not supported. WHERE IS THE DOCUMENTATION ? ============================ Documentation in Unix man and standard HTML format is available in the doc/man and doc/html directories respectively. Currently, documentation is in reference-style only. The tutorial-style documentation will be provided with future releases of the extension. That is, if I ever get time to do that. Everybody is more than welcome to jump in and help with the docs. HOW TO GET SUPPORT ? ==================== The extension is maintained, enhanced, and distributed freely by the Tcl community. The home for sources and bug/patch database is on SourceForge: http://tcl.sourceforge.net/ Alternatively, you are always welcome to post your questions, problems and/or suggestions relating the extension (or any other Tcl issue) to news:comp.lang.tcl newsgroup. -EOF- thread2.8.0/unix/0000755003604700454610000000000012744437564012311 5ustar dgp771divthread2.8.0/unix/threadUnix.c0000644003604700454610000000140212744437564014565 0ustar dgp771div/* * threadUnix.c -- * * Unix specific aspects for the thread extension. * * see http://dev.activestate.com/doc/howto/thread_model.html * * Some of this code is based on work done by Richard Hipp on behalf of * Conservation Through Innovation, Limited, with their permission. * * Copyright (c) 1998 by Sun Microsystems, Inc. * Copyright (c) 1999,2000 by Scriptics Corporation. * * See the file "license.terms" for information on usage and redistribution * of this file, and for a DISCLAIMER OF ALL WARRANTIES. */ #include "../generic/tclThread.h" /* EOF $RCSfile: threadUnix.c,v $ */ /* Emacs Setup Variables */ /* Local Variables: */ /* mode: C */ /* indent-tabs-mode: nil */ /* c-basic-offset: 4 */ /* End: */ thread2.8.0/unix/CONFIG0000644003604700454610000000334212744437564013203 0ustar dgp771div#!/bin/sh # # This file contains collection of configure directives # for building the Threading extension. # # Comment-out next line if building with GCC compiler. # # CC=gcc; export CC # # # Tcl on Unix (uses public Tcl library) # ---------------------------------------------------- # ../configure --enable-threads # # As of 2.6, the threading extension supports persistent # shared variables.

Building the Tcl thread extension for Unix ============================================= Extension can be compiled on several Unix derivates including various distributions of Linux. Build process is pretty straightforward. I've checked some versions of Solaris, Linux and Darwin, but the extension should compile without problems on any Unix-like operating system with a proper pthreads library implementation. To build on Unix-like operating systems, start with the CONFIG script and see if there is already a combination of the "configure" options which may satisfy your needs. If not, you can run the configure script located in the root of the distribution directory with a choice of supported options yourself. If yes, you can uncomment corresponding lines from the CONFIG script and do: % sh CONFIG Either way, this will create a Makefile which you use to run "make" and "make install". You can use "make clean" to clean the directory from temporary compilation files and/or "make distclean" to additionaly remove local config files. You might want to do "make test" before doing the "make install" in order to run the regression tests on the package. To explore other building options, look into the CONFIG file for more information. Note for NaviServer/AOLserver users ------------------------ The extension can be compiled as a loadable module for the NaviServer/AOLserver version 4.0 or higher. In order to do this, use "--with-naviserver" configure option to specify the directory containing the NaviServer/AOLserver distribution. The CONFIG script has an example how to invoke configure in order to build the extension as NaviServer/AOLserver module. Note, however, that "make install" and "make test" targets are still not supported for NaviServer/AOLserver builds. This will be corrected in one of the future releases. To fine-tune, you might also want to make the tsv::* commands replace the NaviServer/AOLserver built-in nsv_* family of commands, since they are API compatible and provide richer command set plus advanced shared-object storage of shared data. Go to the generic/threadSvCmd.h file and look at the beginning of the file for the: /* #define NSV_COMPAT 1 */ So, uncomment the line, recompile and there you go. II. Building optional support libraries ======================================= As of 2.6 release, this extension supports persistent shared variables. To use this functionality, you might need to download and compile some other supporting libraries. Currently, there is a simple implementation of shared variable persistency built atop of popular GNU Gdbm package. You can obtain the latest version of the Gdbm package from the GNU website at: http://www.gnu.org/software/gdbm/gdbm.html To compile with GNU Gdbm support you must configure with --with-gdbm switch. This option, if used, will try to locate the Gdbm library on your system at couple of standard locations. You might override this behaviour by giving --with-gdbm=/some/dir. Note that both library file and the include file must then reside in this directory. -EOF- thread2.8.0/aclocal.m40000664003604700454610000001127712726254163013170 0ustar dgp771div# # Pull in the standard Tcl autoconf macros. # If you don't have the "tclconfig" subdirectory, it is a dependent CVS # module.
