Refer to chapter "Client Authentication" for a # complete description. A short synopsis follows. # # This file controls: which hosts are allowed to connect, how clients # are authenticated, which user names they can use, which databases they # can access. Records take one of these forms: # # local DATABASE USER METHOD [OPTION] # host DATABASE USER CIDR-ADDRESS METHOD [OPTION] # # (The uppercase items must be replaced by actual values.) # # The first field is the connection type: "local" is a Unix-domain # socket, "host" is either a plain or SSL-encrypted TCP/IP socket. # # DATABASE can be "all", "sameuser", a database name, or a comma-separated # list thereof. Note that "samegroup" like in PostgreSQL's pg_hba.conf # file is not supported, since pgpool does not know which group a user # belongs to. Also note that the database specified here may not exist in # the backend PostgreSQL. pgpool will authenticate based on the database's # name, not based on whether it exists or not. # # USER can be "all", a user name, or a comma-separated list thereof. In # both the DATABASE and USER fields you can also write a file name prefixed # with "@" to include names from a separate file. Note that a group name # prefixed with "+" like in PostgreSQL's pg_hba.conf file is not supported # because of the same reason as "samegroup" token. Also note that a user # name specified here may not exist in the backend PostgreSQL. pgpool will # authenticate based on the user's name, not based on whether he/she exists. # # CIDR-ADDRESS specifies the set of hosts the record matches. # It is made up of an IP address and a CIDR mask that is an integer # (between 0 and 32 (IPv4) that specifies the number of significant bits in # the mask. Alternatively, you can write an IP address and netmask in # separate columns to specify the set of hosts. # # METHOD can be "trust", "reject", "md5" or "pam". Note that "pam" sends passwords # in clear text. # # OPTION is the name of the PAM service. Default service name is "pgpool" # # Database and user names containing spaces, commas, quotes and other special # characters must be quoted. Quoting one of the keywords "all" or "sameuser" # makes the name lose its special character, and just match a database or # username with that name. # # This file is read on pgpool startup. If you edit the file on a running # system, you have to restart the pgpool for the changes to take effect. # Put your actual configuration here # ---------------------------------- # # If you want to allow non-local connections, you need to add more # "host" records. In that case you will also need to make pgpool listen # on a non-local interface via the listen_addresses configuration parameter. # # TYPE DATABASE USER CIDR-ADDRESS METHOD # "local" is for Unix domain socket connections only local all all trust # IPv4 local connections: host all all 127.0.0.1/32 trust host all all ::1/128 trust pgpool-II-3.6.1/src/sample/pgpool.conf.sample-replication0000664000175000017500000010276713030105316020256 00000000000000# ---------------------------- # pgPool-II configuration file # ---------------------------- # # This file consists of lines of the form: # # name = value # # Whitespace may be used.

To execute regress.sh you need to install: - pgpool_setup - PostgreSQL 8.3 or later (requires EXTENSION) - pgbench - perl PostgreSQL interface - other tools or libraries required in each test cases regress.sh: the regression test driver. To execute the test, type "sh regress.sh". To get the lists of arguments accepted by regress.sh type "sh regress.sh -?" clean.sh: remove files including PostgreSQL DB clusters created by regress.sh. tests: test scripts live here. Each test case has its own subdirectory. In the directory the test script resides and the script name must be "test.sh". The script should return exit code 0 upon successfull completion of the test. Otherwise it should return non 0 value. To add a new test case, simply create a shell script under this. The test name "001.*" to "050.*" is for regular regression tests, while after "051.*" are for bugs. regress.sh exports following environment variables which can be used by test scripts. PGPOOL_SETUP file path of pgpool_setup file PGPOOL_INSTALL_DIR pgpool-II installed directory PGBIN directory path containing PostgreSQL binaries JDBC_DRIVER file path of JDBC driver log: any output of the test files above is created under the directory. The log file name is same as the test name. libs.sh: contains some useful bash functions.

Also, it's important to keep in mind that this code may * get called from within an aborted transaction, in which case operations * such as syscache lookups are unsafe. * * Some notes about recursion and errors during error processing: * * We need to be robust about recursive-error scenarios --- for example, * if we run out of memory, it's important to be able to report that fact. * There are a number of considerations that go into this. * * First, distinguish between re-entrant use and actual recursion. It * is possible for an error or warning message to be emitted while the * parameters for an error message are being computed. In this case * errstart has been called for the outer message, and some field values * may have already been saved, but we are not actually recursing. We handle * this by providing a (small) stack of ErrorData records. The inner message * can be computed and sent without disturbing the state of the outer message. * (If the inner message is actually an error, this isn't very interesting * because control won't come back to the outer message generator ... but * if the inner message is only debug or log data, this is critical.) * * Second, actual recursion will occur if an error is reported by one of * the elog.c routines or something they call. By far the most probable * scenario of this sort is "out of memory"; and it's also the nastiest * to handle because we'd likely also run out of memory while trying to * report this error! Our escape hatch for this case is to reset the * ErrorContext to empty before trying to process the inner error.

MemoryContextCreate() attempts to allocate the context node, * plus space for the name. If this fails we can ereport() with no * damage done. * 3. We fill in all of the type-independent MemoryContext fields. * 4. We call the type-specific init routine (using the methods pointer). * The init routine is required to make the node minimally valid * with zero chance of failure --- it can't allocate more memory, * for example. * 5. Now we have a minimally valid node that can behave correctly * when told to reset or delete itself. We link the node to its * parent (if any), making the node part of the context tree. * 6. We return to the context-type-specific routine, which finishes * up type-specific initialization. This routine can now do things * that might fail (like allocate more memory), so long as it's * sure the node is left in a state that delete will handle. * * This protocol doesn't prevent us from leaking memory if step 6 fails * during creation of a top-level context, since there's no parent link * in that case. However, if you run out of memory while you're building * a top-level context, you might as well go home anyway... * * Normally, the context node and the name are allocated from * TopMemoryContext (NOT from the parent context, since the node must * survive resets of its parent context!). However, this routine is itself * used to create TopMemoryContext! If we see that TopMemoryContext is NULL, * we assume we are creating TopMemoryContext and use malloc() to allocate * the node. * * Note that the name field of a MemoryContext does not point to * separately-allocated storage, so it should not be freed at context * deletion. *-------------------- */ MemoryContext MemoryContextCreate(NodeTag tag, Size size, MemoryContextMethods *methods, MemoryContext parent, const char *name) { MemoryContext node;

AllocSet...() does not use OrderedSet...() any more. * Instead it manages allocations in a block pool by itself, combining * many small allocations in a few bigger blocks. AllocSetFree() normally * doesn't free() memory really. It just add's the free'd area to some * list for later reuse by AllocSetAlloc(). All memory blocks are free()'d * at once on AllocSetReset(), which happens when the memory context gets * destroyed. * Jan Wieck * * Performance improvement from Tom Lane, 8/99: for extremely large request * sizes, we do want to be able to give the memory back to free() as soon * as it is pfree()'d. Otherwise we risk tying up a lot of memory in * freelist entries that might never be usable. This is specially needed * when the caller is repeatedly repalloc()'ing a block bigger and bigger; * the previous instances of the block were guaranteed to be wasted until * AllocSetReset() under the old way. * * Further improvement 12/00: as the code stood, request sizes in the * midrange between "small" and "large" were handled very inefficiently, * because any sufficiently large free chunk would be used to satisfy a * request, even if it was much larger than necessary. This led to more * and more wasted space in allocated chunks over time. To fix, get rid * of the midrange behavior: we now handle only "small" power-of-2-size * chunks as chunks. Anything "large" is passed off to malloc(). Change * the number of freelists to change the small/large boundary. * * * About CLOBBER_FREED_MEMORY: * * If this symbol is defined, all freed memory is overwritten with 0x7F's. * This is useful for catching places that reference already-freed memory. * * About MEMORY_CONTEXT_CHECKING: * * Since we usually round request sizes up to the next power of 2, there * is often some unused space immediately after a requested data area. * Thus, if someone makes the common error of writing past what they've * requested, the problem is likely to go unnoticed ... until the day when * there *isn't* any wasted space, perhaps because of different memory * alignment on a new platform, or some other effect. To catch this sort * of problem, the MEMORY_CONTEXT_CHECKING option stores 0x7E just beyond * the requested space whenever the request is less than the actual chunk * size, and verifies that the byte is undamaged when the chunk is freed. * * * About USE_VALGRIND and Valgrind client requests: * * Valgrind provides "client request" macros that exchange information with * the host Valgrind (if any). Under !USE_VALGRIND, memdebug.h stubs out * currently-used macros. * * When running under Valgrind, we want a NOACCESS memory region both before * and after the allocation. The chunk header is tempting as the preceding * region, but mcxt.c expects to able to examine the standard chunk header * fields. Therefore, we use, when available, the requested_size field and * any subsequent padding. requested_size is made NOACCESS before returning * a chunk pointer to a caller. However, to reduce client request traffic, * it is kept DEFINED in chunks on the free list. * * The rounded-up capacity of the chunk usually acts as a post-allocation * NOACCESS region. If the request consumes precisely the entire chunk, * there is no such region; another chunk header may immediately follow. In * that case, Valgrind will not detect access beyond the end of the chunk. * * See also the cooperating Valgrind client requests in mcxt.c. * *------------------------------------------------------------------------- */ #include "pool_type.h" #include "utils/palloc.h" #include "utils/memdebug.h" #include "utils/memutils.h" #include "utils/elog.h" #include #include /* Define this to detail debug alloc information */ /* #define HAVE_ALLOCINFO */ /*-------------------- * Chunk freelist k holds chunks of size 1 << (k + ALLOC_MINBITS), * for k = 0 ..

If you make use of SET variables, then you * will do the wrong thing in multi-query strings like this: * SET SQL_inheritance TO off; SELECT * FROM foo; * because the entire string is parsed by gram.y before the SET gets * executed. Anything that depends on the database or changeable state * should be handled during parse analysis so that it happens at the * right time not the wrong time.
