mbuffer-20161115/ChangeLog0000644000000000000000000004610013012427435013304 0ustar 0000000000000020161115: - enhancement: report percent done, when input size is known (is a file) - enhancement: watchdog raises SIGKILL if SIGINT had no effect - change: start watchdog when parsing option -W or after parsing all options when activated via defaults file => Originally the watchdog was started after output to make sure output initialization doesn't unintentionally trigger the watchdog due to delays with a manual setup on the receiving side in a network situation. => This behavior limits potential benefits when mbuffer is used in an automated environment where output initialization might fail and the watchdog would be of use. => To avoid triggering the watchdog during network initialization, put the watchdog option -W after network options -O and -I. - fix: use thread-safe mt_usleep instead of sleep(3) for watchdog timing - change: adjusted interface of mt_usleep to accept 64bit arguments 20160613: - fix: fix potential assertion triggered by interrupted system call - enhancement: ignore EINTR for I/O syscalls 20160228: - fix: fix listen's backlog argument, which can cause issues on Linux 4.4 (patch by Matthijs van Drunen) 20151002: - fix: SegV when argument to -v is missing - fix: potential infinite loop on output error 20150412: - fix: watchdog cannot do its job

options - added a watchdog that terminates mbuffer if input or output activity stalls (option -W) 20120505: - fixed IPv6 client initialization on FreeBSD - fix: suppress summary on stderr if -q is used with -l - fix: option -P 100 may lead to hang 20110724: - fix: garbage might be written after input error - enhancement: prompt for additional volumes for argument "-n 0" - enhancement: prompt for next volume on I/O error if -n is set (some tape devices incorrectly return -1/EIO instead of 0) - enhancement: added option to append to output file - update: remove use of deprecated interface sigignore 20110317: - fix: terminate ASAP if no working output is available - enhancement: added option to terminate on any error - fix: mbuffer blocks on SIGTTIN when started in background - fix: display correct dimensions (e.g. kiB instead of kB) 20110119: - Anniversary: 10 years of mbuffer - fix for building on cygwin in a separate directory - fix: incorrect sanity check concerning hashing and multivolume support (patch by Sean Walmsley) 20101230: - enhancement: hash should show up in log file - enhancement: report last block number on volume - enhancement: report times for each volume and tape changes - cosmetic fix: need to convert thread ids to long for linux - build enhancement: better cygwin and packaging environment support 20100526: - fix: potential deadlock on SIGINT related to watermark algorithm - fix: high watermark algorithm interferes with rate limitation 20100327: - fix: hash calculation is omitted if no output is set - fix: test procedure doesn't wait on Solaris 8

- added IPv6 support - added support for port name lookup - added another verbosity level for I/O messages - refix libmhash initialization 20090215: - fix status thread hang on very small transfer sizes - fix libmhash initialization - -q should not suppress output of -H - reduced termination latency with status display running - update for summary display - changed default shell make shell to /bin/sh 20090113: - fix for assertion failure of 64bit binaries in network code 20090106: - BSD compatibility update - replace use of deprecated atoi with strtol - better argument checking for numeric options - enhanced semaphore limits checking - add phony targets 20081207: - fixed some typos in man page - TCP buffer tuning could be a little bit more intelligent - fixed formating of some info messages - tuneable TCP buffer with option --tcpbuffer 20081113: - tune send and receive buffer of TCP stack to match block size - added target check to Makefile - fix: don't mix up file during open - code cleanup/unification for MD5 - sendfile should also be used for writing to files - sync cleanup on output thread instead of input thread - fix: access to dest_t after free() - unified summary and join between verbose and silent mode - minor code cleanups 20081023: - mbuffer should not abort on SIGTERM - mbuffer should not segv on invalid arguments for options -m, -s - transfer statistics should wait for the first block to be received - minor code path optimization - option -n should accept -n1 20081015: - FIX REGRESSION: stdout may be corrupted by mbuffer (This regression was the

cause a SegV - $(LIBS) should be after $(OBJECTS) 20080502: - better support for device special files (files under /dev shouldn't need -f to write to) - update to always handle largefile correctly - fix configure script for sendfile functionality - allow in-memory locking of file based buffers - minor docu updates - minor build update (compile with -c -O, mbuffer.o is dependent on Makefile) 20080329: - configure should check if ST_BLKSIZE feature is available - compile with -O instead of -g per default - hostnames may have underscores and/or dash - orthographic fix - use inline and restrict if available - honor --disable-assert - use directio for input, too 20080212: - fixed a race-condition causing incorrectly written last block 20080122: - fix wrong assertion on dup2 - fix 'make distclean' to also remove mbuffer.exe - fix installation of manpage 20080104: - updated status display - POSIX conformance update: read from stderr instead of relying on /dev/tty exists,

for MD5 functions in libmd5 using different function to avoid incorrect caching of results 20070518: - bugfix: misplaced ifdef could lead to failures for options -d and -b on systems that do not support device block size determination - fixed possible hang on SIGINT without status thread - write summary to stderr if no tty is available 20070502: - added support for setting the output device's volume size explicitly (patch by Sean Walmsley) - minor cleanups - make locking more solid (in theory [only], a deadlock could have occurred) - assert() everything 20070401: - prefix name of executable before every message - added some missing newlines - set dependency for "make install" on "make" (i.e. "make install" also builds mbuffer) 20070317: - fix: mbuffer erroneously return with EXIT_SUCCESS when it got interrupted by SIGINT or SIGTERM 20060728: - changed signal handling to prevent syscalls returning with EINTR in reader and writer - fix for warnings, fatals, and errors getting truncated - sleep before printing I/O rates for the first time to prevent showing insane values 20060704: - use condition variables to safely signal crossing of watermarks - include times full/empty (crossing of low/high watermark) in summary (proposal by Alex Kramarov) - enhanced status and summary output to be display stats with a higher precisions 20060626: - bugfix and enhancement for rate limitation code - fixed regressions caused by switching from float to double - make sure outputThread doesn't start initially if -P is set - write debug logs a little bit more thread friendly

synchronous data integrity I/O: This was enabled by default until now, but may cause a decrease in performance as it requires a higher number of I/O ops. On systems without full synchronous data integrity support, no difference will be observable concerning performance. Systems that support it, will gain increased performace without -c, but error reporting will be more precise with -c. - changed errormessages to include offset - added support for Solaris' directio hinting - made memlock support an automagic option (compiled in if available) - simplify CFLAGS overriding - more portable largefile support solution - minimized configure script - default to native compiler instead of gcc 20060217: - made signal handling more standards conforming - use deferred cancellation instead of asynchronous - fixed some debug messages - use sendfile only for sockets 20060126: - clarified some errormessages - fixed some typos - updated README file 20051006: - added support for sendfile (AFAIK only the Solaris version supports sending from buffers) - added memory locking support - added support to set buffer size as percentage of physical memory - open file with O_LARGEFILE per default - added some command-line options for existing functionality (-H, -V) - compile as 64bit executable on opteron and sparc architectures by default - defaulting to /var/tmp for buffer files, as /tmp is a swap based filesystem on some operating systems - use TMPDIR environment variable if available to determine where to put a buffer file 20051003: - increased maximum value of number of blocks - doku updates - openssl build fixes - fixed some warnings - install man page to correct location - reuse networking sockets - do not bail out if output does not support syncing (thank you to Wolfgang Denk for some suggestions) 20050730: - made mbuffer.c lint clean - fixed some types - Makefile fix for install 20050726: - added support for openssl based md5 hashing - support of transfer summary in gigabyte - support for passing buffer size in gigabyte (G) (please pass the relevant CFLAGS for 64Bit executables for your compiler to configure) - added support for passing command to autoloader (patch submitted by Wolfgang Denk) - enhanced network parameter parsing - FIX: transient error in status display - FIX: mbuffer could hang on first SIGINT (chance 1/3) - fixed a bug in network client verification code - pass CFLAGS also to link phase - unlink tmpfile as early as possible - check close for errors (see Chris Gerhard's Weblog concerning close on http://blogs.sun.com/roller/page/chrisg?anchor=did_that_close_succeed) - additional sanity checks for buffer limits 20050510: - fixed possible lockup upon SIGINT - fixed displayed time - updated display to change to MB instead of kB when > 3072kB 20050321: - compile time fix for gentoo and suse 9.2 - made --enable-debug and --enable-md5 work - gcc optimization flag set to -O2, -O as default 20050125: - fixed operation of low watermark (-p) - made printf formating more standard conforming - start output before input thread - more minor fixes 20050124 (unannounced interims version): - fixed summary bug reported - kicked automake - removed locale support (too much work to support properly) - changed debugmsg to a C99 macro, if debugging is switched off - fix: final newline of statusThread was printf()ed to stderr instead of Terminal - fix: potential incorrect written last block - fixed warnings: comparison of signed and unsigned - beautified summary - added low watermark (request by Greg Freemyer) (restarts reading if dropped below - needed for FAST streamers; I don't have such a beast and I never expected such a thing to exist...)

Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed. Preamble The GNU General Public License is a free, copyleft license for software and other kinds of works. The licenses for most software and other practical works are designed to take away your freedom to share and change the works. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change all versions of a program--to make sure it remains free software for all its users. We, the Free Software Foundation, use the GNU General Public License for most of our software; it applies also to any other work released this way by its authors. You can apply it to your programs, too. When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for them if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs, and that you know you can do these things. To protect your rights, we need to prevent others from denying you these rights or asking you to surrender the rights. Therefore, you have certain responsibilities if you distribute copies of the software, or if you modify it: responsibilities to respect the freedom of others. For example, if you distribute copies of such a program, whether gratis or for a fee, you must pass on to the recipients the same freedoms that you received. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights. Developers that use the GNU GPL protect your rights with two steps: (1) assert copyright on the software, and (2) offer you this License giving you legal permission to copy, distribute and/or modify it. For the developers' and authors' protection, the GPL clearly explains that there is no warranty for this free software. For both users' and authors' sake, the GPL requires that modified versions be marked as changed, so that their problems will not be attributed erroneously to authors of previous versions. Some devices are designed to deny users access to install or run modified versions of the software inside them, although the manufacturer can do so. This is fundamentally incompatible with the aim of protecting users' freedom to change the software. The systematic pattern of such abuse occurs in the area of products for individuals to use, which is precisely where it is most unacceptable. Therefore, we have designed this version of the GPL to prohibit the practice for those products. If such problems arise substantially in other domains, we stand ready to extend this provision to those domains in future versions of the GPL, as needed to protect the freedom of users. Finally, every program is threatened constantly by software patents. States should not allow patents to restrict development and use of software on general-purpose computers, but in those that do, we wish to avoid the special danger that patents applied to a free program could make it effectively proprietary. To prevent this, the GPL assures that patents cannot be used to render the program non-free. The precise terms and conditions for copying, distribution and modification follow. TERMS AND CONDITIONS 0. Definitions. "This License" refers to version 3 of the GNU General Public License. "Copyright" also means copyright-like laws that apply to other kinds of works, such as semiconductor masks. "The Program" refers to any copyrightable work licensed under this License. Each licensee is addressed as "you". "Licensees" and "recipients" may be individuals or organizations. To "modify" a work means to copy from or adapt all or part of the work in a fashion requiring copyright permission, other than the making of an exact copy. The resulting work is called a "modified version" of the earlier work or a work "based on" the earlier work. A "covered work" means either the unmodified Program or a work based on the Program. To "propagate" a work means to do anything with it that, without permission, would make you directly or secondarily liable for infringement under applicable copyright law, except executing it on a computer or modifying a private copy. Propagation includes copying, distribution (with or without modification), making available to the public, and in some countries other activities as well. To "convey" a work means any kind of propagation that enables other parties to make or receive copies. Mere interaction with a user through a computer network, with no transfer of a copy, is not conveying. An interactive user interface displays "Appropriate Legal Notices" to the extent that it includes a convenient and prominently visible feature that (1) displays an appropriate copyright notice, and (2) tells the user that there is no warranty for the work (except to the extent that warranties are provided), that licensees may convey the work under this License, and how to view a copy of this License. If the interface presents a list of user commands or options, such as a menu, a prominent item in the list meets this criterion. 1. Source Code. The "source code" for a work means the preferred form of the work for making modifications to it. "Object code" means any non-source form of a work. A "Standard Interface" means an interface that either is an official standard defined by a recognized standards body, or, in the case of interfaces specified for a particular programming language, one that is widely used among developers working in that language. The "System Libraries" of an executable work include anything, other than the work as a whole, that (a) is included in the normal form of packaging a Major Component, but which is not part of that Major Component, and (b) serves only to enable use of the work with that Major Component, or to implement a Standard Interface for which an implementation is available to the public in source code form. A "Major Component", in this context, means a major essential component (kernel, window system, and so on) of the specific operating system (if any) on which the executable work runs, or a compiler used to produce the work, or an object code interpreter used to run it. The "Corresponding Source" for a work in object code form means all the source code needed to generate, install, and (for an executable work) run the object code and to modify the work, including scripts to control those activities. However, it does not include the work's System Libraries, or general-purpose tools or generally available free programs which are used unmodified in performing those activities but which are not part of the work. For example, Corresponding Source includes interface definition files associated with source files for the work, and the source code for shared libraries and dynamically linked subprograms that the work is specifically designed to require, such as by intimate data communication or control flow between those subprograms and other parts of the work. The Corresponding Source need not include anything that users can regenerate automatically from other parts of the Corresponding Source. The Corresponding Source for a work in source code form is that same work. 2. Basic Permissions. All rights granted under this License are granted for the term of copyright on the Program, and are irrevocable provided the stated conditions are met. This License explicitly affirms your unlimited permission to run the unmodified Program. The output from running a covered work is covered by this License only if the output, given its content, constitutes a covered work. This License acknowledges your rights of fair use or other equivalent, as provided by copyright law. You may make, run and propagate covered works that you do not convey, without conditions so long as your license otherwise remains in force. You may convey covered works to others for the sole purpose of having them make modifications exclusively for you, or provide you with facilities for running those works, provided that you comply with the terms of this License in conveying all material for which you do not control copyright. Those thus making or running the covered works for you must do so exclusively on your behalf, under your direction and control, on terms that prohibit them from making any copies of your copyrighted material outside their relationship with you. Conveying under any other circumstances is permitted solely under the conditions stated below. Sublicensing is not allowed; section 10 makes it unnecessary. 3. Protecting Users' Legal Rights From Anti-Circumvention Law. No covered work shall be deemed part of an effective technological measure under any applicable law fulfilling obligations under article 11 of the WIPO copyright treaty adopted on 20 December 1996, or similar laws prohibiting or restricting circumvention of such measures. When you convey a covered work, you waive any legal power to forbid circumvention of technological measures to the extent such circumvention is effected by exercising rights under this License with respect to the covered work, and you disclaim any intention to limit operation or modification of the work as a means of enforcing, against the work's users, your or third parties' legal rights to forbid circumvention of technological measures. 4. Conveying Verbatim Copies. You may convey verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice; keep intact all notices stating that this License and any non-permissive terms added in accord with section 7 apply to the code; keep intact all notices of the absence of any warranty; and give all recipients a copy of this License along with the Program. You may charge any price or no price for each copy that you convey, and you may offer support or warranty protection for a fee. 5. Conveying Modified Source Versions. You may convey a work based on the Program, or the modifications to produce it from the Program, in the form of source code under the terms of section 4, provided that you also meet all of these conditions: a) The work must carry prominent notices stating that you modified it, and giving a relevant date. b) The work must carry prominent notices stating that it is released under this License and any conditions added under section 7. This requirement modifies the requirement in section 4 to "keep intact all notices". c) You must license the entire work, as a whole, under this License to anyone who comes into possession of a copy. This License will therefore apply, along with any applicable section 7 additional terms, to the whole of the work, and all its parts, regardless of how they are packaged. This License gives no permission to license the work in any other way, but it does not invalidate such permission if you have separately received it. d) If the work has interactive user interfaces, each must display Appropriate Legal Notices; however, if the Program has interactive interfaces that do not display Appropriate Legal Notices, your work need not make them do so. A compilation of a covered work with other separate and independent works, which are not by their nature extensions of the covered work, and which are not combined with it such as to form a larger program, in or on a volume of a storage or distribution medium, is called an "aggregate" if the compilation and its resulting copyright are not used to limit the access or legal rights of the compilation's users beyond what the individual works permit. Inclusion of a covered work in an aggregate does not cause this License to apply to the other parts of the aggregate. 6. Conveying Non-Source Forms. You may convey a covered work in object code form under the terms of sections 4 and 5, provided that you also convey the machine-readable Corresponding Source under the terms of this License, in one of these ways: a) Convey the object code in, or embodied in, a physical product (including a physical distribution medium), accompanied by the Corresponding Source fixed on a durable physical medium customarily used for software interchange. b) Convey the object code in, or embodied in, a physical product (including a physical distribution medium), accompanied by a written offer, valid for at least three years and valid for as long as you offer spare parts or customer support for that product model, to give anyone who possesses the object code either (1) a copy of the Corresponding Source for all the software in the product that is covered by this License, on a durable physical medium customarily used for software interchange, for a price no more than your reasonable cost of physically performing this conveying of source, or (2) access to copy the Corresponding Source from a network server at no charge. c) Convey individual copies of the object code with a copy of the written offer to provide the Corresponding Source. This alternative is allowed only occasionally and noncommercially, and only if you received the object code with such an offer, in accord with subsection 6b. d) Convey the object code by offering access from a designated place (gratis or for a charge), and offer equivalent access to the Corresponding Source in the same way through the same place at no further charge. You need not require recipients to copy the Corresponding Source along with the object code. If the place to copy the object code is a network server, the Corresponding Source may be on a different server (operated by you or a third party) that supports equivalent copying facilities, provided you maintain clear directions next to the object code saying where to find the Corresponding Source. Regardless of what server hosts the Corresponding Source, you remain obligated to ensure that it is available for as long as needed to satisfy these requirements. e) Convey the object code using peer-to-peer transmission, provided you inform other peers where the object code and Corresponding Source of the work are being offered to the general public at no charge under subsection 6d. A separable portion of the object code, whose source code is excluded from the Corresponding Source as a System Library, need not be included in conveying the object code work. A "User Product" is either (1) a "consumer product", which means any tangible personal property which is normally used for personal, family, or household purposes, or (2) anything designed or sold for incorporation into a dwelling. In determining whether a product is a consumer product, doubtful cases shall be resolved in favor of coverage. For a particular product received by a particular user, "normally used" refers to a typical or common use of that class of product, regardless of the status of the particular user or of the way in which the particular user actually uses, or expects or is expected to use, the product. A product is a consumer product regardless of whether the product has substantial commercial, industrial or non-consumer uses, unless such uses represent the only significant mode of use of the product. "Installation Information" for a User Product means any methods, procedures, authorization keys, or other information required to install and execute modified versions of a covered work in that User Product from a modified version of its Corresponding Source. The information must suffice to ensure that the continued functioning of the modified object code is in no case prevented or interfered with solely because modification has been made. If you convey an object code work under this section in, or with, or specifically for use in, a User Product, and the conveying occurs as part of a transaction in which the right of possession and use of the User Product is transferred to the recipient in perpetuity or for a fixed term (regardless of how the transaction is characterized), the Corresponding Source conveyed under this section must be accompanied by the Installation Information. But this requirement does not apply if neither you nor any third party retains the ability to install modified object code on the User Product (for example, the work has been installed in ROM). The requirement to provide Installation Information does not include a requirement to continue to provide support service, warranty, or updates for a work that has been modified or installed by the recipient, or for the User Product in which it has been modified or installed. Access to a network may be denied when the modification itself materially and adversely affects the operation of the network or violates the rules and protocols for communication across the network. Corresponding Source conveyed, and Installation Information provided, in accord with this section must be in a format that is publicly documented (and with an implementation available to the public in source code form), and must require no special password or key for unpacking, reading or copying. 7. Additional Terms. "Additional permissions" are terms that supplement the terms of this License by making exceptions from one or more of its conditions. Additional permissions that are applicable to the entire Program shall be treated as though they were included in this License, to the extent that they are valid under applicable law. If additional permissions apply only to part of the Program, that part may be used separately under those permissions, but the entire Program remains governed by this License without regard to the additional permissions. When you convey a copy of a covered work, you may at your option remove any additional permissions from that copy, or from any part of it. (Additional permissions may be written to require their own removal in certain cases when you modify the work.) You may place additional permissions on material, added by you to a covered work, for which you have or can give appropriate copyright permission. Notwithstanding any other provision of this License, for material you add to a covered work, you may (if authorized by the copyright holders of that material) supplement the terms of this License with terms: a) Disclaiming warranty or limiting liability differently from the terms of sections 15 and 16 of this License; or b) Requiring preservation of specified reasonable legal notices or author attributions in that material or in the Appropriate Legal Notices displayed by works containing it; or c) Prohibiting misrepresentation of the origin of that material, or requiring that modified versions of such material be marked in reasonable ways as different from the original version; or d) Limiting the use for publicity purposes of names of licensors or authors of the material; or e) Declining to grant rights under trademark law for use of some trade names, trademarks, or service marks; or f) Requiring indemnification of licensors and authors of that material by anyone who conveys the material (or modified versions of it) with contractual assumptions of liability to the recipient, for any liability that these contractual assumptions directly impose on those licensors and authors. All other non-permissive additional terms are considered "further restrictions" within the meaning of section 10. If the Program as you received it, or any part of it, contains a notice stating that it is governed by this License along with a term that is a further restriction, you may remove that term. If a license document contains a further restriction but permits relicensing or conveying under this License, you may add to a covered work material governed by the terms of that license document, provided that the further restriction does not survive such relicensing or conveying. If you add terms to a covered work in accord with this section, you must place, in the relevant source files, a statement of the additional terms that apply to those files, or a notice indicating where to find the applicable terms. Additional terms, permissive or non-permissive, may be stated in the form of a separately written license, or stated as exceptions; the above requirements apply either way. 8. Termination. You may not propagate or modify a covered work except as expressly provided under this License. Any attempt otherwise to propagate or modify it is void, and will automatically terminate your rights under this License (including any patent licenses granted under the third paragraph of section 11). However, if you cease all violation of this License, then your license from a particular copyright holder is reinstated (a) provisionally, unless and until the copyright holder explicitly and finally terminates your license, and (b) permanently, if the copyright holder fails to notify you of the violation by some reasonable means prior to 60 days after the cessation. Moreover, your license from a particular copyright holder is reinstated permanently if the copyright holder notifies you of the violation by some reasonable means, this is the first time you have received notice of violation of this License (for any work) from that copyright holder, and you cure the violation prior to 30 days after your receipt of the notice. Termination of your rights under this section does not terminate the licenses of parties who have received copies or rights from you under this License. If your rights have been terminated and not permanently reinstated, you do not qualify to receive new licenses for the same material under section 10. 9. Acceptance Not Required for Having Copies. You are not required to accept this License in order to receive or run a copy of the Program. Ancillary propagation of a covered work occurring solely as a consequence of using peer-to-peer transmission to receive a copy likewise does not require acceptance. However, nothing other than this License grants you permission to propagate or modify any covered work. These actions infringe copyright if you do not accept this License. Therefore, by modifying or propagating a covered work, you indicate your acceptance of this License to do so. 10. Automatic Licensing of Downstream Recipients. Each time you convey a covered work, the recipient automatically receives a license from the original licensors, to run, modify and propagate that work, subject to this License. You are not responsible for enforcing compliance by third parties with this License. An "entity transaction" is a transaction transferring control of an organization, or substantially all assets of one, or subdividing an organization, or merging organizations. If propagation of a covered work results from an entity transaction, each party to that transaction who receives a copy of the work also receives whatever licenses to the work the party's predecessor in interest had or could give under the previous paragraph, plus a right to possession of the Corresponding Source of the work from the predecessor in interest, if the predecessor has it or can get it with reasonable efforts. You may not impose any further restrictions on the exercise of the rights granted or affirmed under this License. For example, you may not impose a license fee, royalty, or other charge for exercise of rights granted under this License, and you may not initiate litigation (including a cross-claim or counterclaim in a lawsuit) alleging that any patent claim is infringed by making, using, selling, offering for sale, or importing the Program or any portion of it. 11. Patents. A "contributor" is a copyright holder who authorizes use under this License of the Program or a work on which the Program is based. The work thus licensed is called the contributor's "contributor version". A contributor's "essential patent claims" are all patent claims owned or controlled by the contributor, whether already acquired or hereafter acquired, that would be infringed by some manner, permitted by this License, of making, using, or selling its contributor version, but do not include claims that would be infringed only as a consequence of further modification of the contributor version. For purposes of this definition, "control" includes the right to grant patent sublicenses in a manner consistent with the requirements of this License. Each contributor grants you a non-exclusive, worldwide, royalty-free patent license under the contributor's essential patent claims, to make, use, sell, offer for sale, import and otherwise run, modify and propagate the contents of its contributor version. In the following three paragraphs, a "patent license" is any express agreement or commitment, however denominated, not to enforce a patent (such as an express permission to practice a patent or covenant not to sue for patent infringement). To "grant" such a patent license to a party means to make such an agreement or commitment not to enforce a patent against the party. If you convey a covered work, knowingly relying on a patent license, and the Corresponding Source of the work is not available for anyone to copy, free of charge and under the terms of this License, through a publicly available network server or other readily accessible means, then you must either (1) cause the Corresponding Source to be so available, or (2) arrange to deprive yourself of the benefit of the patent license for this particular work, or (3) arrange, in a manner consistent with the requirements of this License, to extend the patent license to downstream recipients. "Knowingly relying" means you have actual knowledge that, but for the patent license, your conveying the covered work in a country, or your recipient's use of the covered work in a country, would infringe one or more identifiable patents in that country that you have reason to believe are valid. If, pursuant to or in connection with a single transaction or arrangement, you convey, or propagate by procuring conveyance of, a covered work, and grant a patent license to some of the parties receiving the covered work authorizing them to use, propagate, modify or convey a specific copy of the covered work, then the patent license you grant is automatically extended to all recipients of the covered work and works based on it. A patent license is "discriminatory" if it does not include within the scope of its coverage, prohibits the exercise of, or is conditioned on the non-exercise of one or more of the rights that are specifically granted under this License. You may not convey a covered work if you are a party to an arrangement with a third party that is in the business of distributing software, under which you make payment to the third party based on the extent of your activity of conveying the work, and under which the third party grants, to any of the parties who would receive the covered work from you, a discriminatory patent license (a) in connection with copies of the covered work conveyed by you (or copies made from those copies), or (b) primarily for and in connection with specific products or compilations that contain the covered work, unless you entered into that arrangement, or that patent license was granted, prior to 28 March 2007. Nothing in this License shall be construed as excluding or limiting any implied license or other defenses to infringement that may otherwise be available to you under applicable patent law. 12. No Surrender of Others' Freedom. If conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot convey a covered work so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not convey it at all. For example, if you agree to terms that obligate you to collect a royalty for further conveying from those to whom you convey the Program, the only way you could satisfy both those terms and this License would be to refrain entirely from conveying the Program. 13. Use with the GNU Affero General Public License. Notwithstanding any other provision of this License, you have permission to link or combine any covered work with a work licensed under version 3 of the GNU Affero General Public License into a single combined work, and to convey the resulting work. The terms of this License will continue to apply to the part which is the covered work, but the special requirements of the GNU Affero General Public License, section 13, concerning interaction through a network will apply to the combination as such. 14. Revised Versions of this License. The Free Software Foundation may publish revised and/or new versions of the GNU General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Program specifies that a certain numbered version of the GNU General Public License "or any later version" applies to it, you have the option of following the terms and conditions either of that numbered version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of the GNU General Public License, you may choose any version ever published by the Free Software Foundation. If the Program specifies that a proxy can decide which future versions of the GNU General Public License can be used, that proxy's public statement of acceptance of a version permanently authorizes you to choose that version for the Program. Later license versions may give you additional or different permissions. However, no additional obligations are imposed on any author or copyright holder as a result of your choosing to follow a later version. 15. Disclaimer of Warranty. THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 16. Limitation of Liability. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. 17. Interpretation of Sections 15 and 16. If the disclaimer of warranty and limitation of liability provided above cannot be given local legal effect according to their terms, reviewing courts shall apply local law that most closely approximates an absolute waiver of all civil liability in connection with the Program, unless a warranty or assumption of liability accompanies a copy of the Program in return for a fee. END OF TERMS AND CONDITIONS How to Apply These Terms to Your New Programs If you develop a new program, and you want it to be of the greatest possible use to the public, the best way to achieve this is to make it free software which everyone can redistribute and change under these terms. To do so, attach the following notices to the program. It is safest to attach them to the start of each source file to most effectively state the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found. Copyright (C) This program is free software: you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation, either version 3 of the License, or (at your option) any later version. This program is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU General Public License for more details. You should have received a copy of the GNU General Public License along with this program. If not, see . Also add information on how to contact you by electronic and paper mail. If the program does terminal interaction, make it output a short notice like this when it starts in an interactive mode: Copyright (C) This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'. This is free software, and you are welcome to redistribute it under certain conditions; type `show c' for details. The hypothetical commands `show w' and `show c' should show the appropriate parts of the General Public License. Of course, your program's commands might be different; for a GUI interface, you would use an "about box". You should also get your employer (if you work as a programmer) or school, if any, to sign a "copyright disclaimer" for the program, if necessary. For more information on this, and how to apply and follow the GNU GPL, see . The GNU General Public License does not permit incorporating your program into proprietary programs. If your program is a subroutine library, you may consider it more useful to permit linking proprietary applications with the library. If this is what you want to do, use the GNU Lesser General Public License instead of this License.

To use it you should know the basics of TCP/IP. Use it only on a trusted LAN, as there is no builtin security. TESTING: ======== to test the program I do the following: # tar cf - /usr | mbuffer | tar tf - > out # tar cf - /usr | mbuffer -t | tar tf - > out ARCHITECTURES and PLATFORMS: ============================ This software has been tested under the following operatingsystems: - solaris 8 (SPARC and x86) and later - no known issues - do not put your temporary files on a tmpfs filesystem, as this is equivalent to a normal memory allocated buffer - linux 2.2 (x86) and later - some pthread versions of linux seem to have problems with cancellation, causing a segmentation fault upon SIGINTR - tru64-alpha - broken display - FreeBSD 5.x (x86) 64 Bit Buffers: =============== The buffer limit is sysconf(_SC_SEM_VALUE_MAX)*Blocksize. This usually limits the maximum number of blocks to 2G-1, because semaphores are implemented using an int, which is on most architectures a 32 Bit word. This limit is currently a non-issue, but might be resolved in a future release, by using condition variables. If the total buffer size is 2GB or larger, you will need to compile mbuffer as a 64bit executable. This requires that you have a 64bit processor. Compiling with gcc you will need to pass -m64 as CFLAGS to configure. E.g.: env CFLAGS="-O -g -m64" ./configure For Sun's Studio Compiler the equivalent flag is -xarch=v9. TODO: ===== # fix: unknown bugs FEEDBACK: ========= It is always nice to get feedback. If you encounter a problem or a bug, send me a note. Requests for enhancements are also welcome.

It is multi-threaded, supports network connections, and offers more options than the standard buffer. .SH "OPTIONS" .LP .TP \fB\-i\fR <\fIfilename\fP> Use \fIfilename\fP as input instead of the standard input (needs to be given for multi volume support). If \fIfilename\fP is \-, input is read from standard input. .TP \fB\-I\fR <\fIport\fP> Use network port \fIport\fP as input instead of the standard input. If given a hostname and a port in the form hostname:port, the first interface with the IP of hostname will be used. .TP \fB\-o\fR <\fIfilename\fP> Use \fIfilename\fP as output instead of the standard output (needs to be given for multi volume support, will enable use of sendfile if available). If \fIfilename\fP is \-, output is written to standard output. The option \-o can be passed multiple times to specify multiple outputs. .TP \fB\-O\fR <\fIhostname:port\fP> Write output to \fIhostname:port\fP instead of the standard output (will enable use of sendfile if available). This option can be used multiple times to send data to multiple machines. .TP \fB\-b\fR <\fInum\fP> Use \fInum\fP blocks for buffer (default 256). .TP \fB\-s\fR <\fIsize\fP> Use blocks of \fIsize\fP bytes for buffer (default pagesize of system). .TP \fB\-m\fR <\fIsize\fP> Use a total of \fIsize\fP bytes for buffer (default 2MB) \- size can be set with a trailing character (b and B for Byte, k for kByte, M for MByte, G for Gigabyte, and with % for a percentage of total physical memory). .TP \fB\-L\fR Lock buffer in memory \- this option is not available for file-based buffers and requires mbuffer to be set-UID root (use with care). .TP \fB\-n\fR <\fInum\fP> \fInum\fP volumes in input device (requires use of option \-i for input device specification, pass 0 as argument if mbuffer should prompt for every new volume) .TP \fB\-t\fR use a memory-mapped temporary file as buffer (use with huge buffers) .TP \fB\-T\fR <\fIfile\fP> as \-t but use \fIfile\fP instead .TP \fB\-d\fR use block-size of device for output (needed for some devices, slows output down) .TP \fB\-D\fR <\fIsize\fP> assume an output volume of \fIsize\fP bytes (default infinite) after which a volume change will be initiated. Small values are useful for the timely testing of multi-volume runs; accurate values if your device doesn't properly signal end of media. Size can be set with a trailing character (b and B for Byte, k for kByte, M for MByte, or G for Gigabyte) .TP \fB\-P\fR <\fInum\fP> start writing after the buffer has been filled to \fInum\fP% (default 0 \- start at once) .TP \fB\-p\fR <\fInum\fP> start reading after the buffer has dropped below fill-ratio of \fInum\fP% (default 100 \- start at once) .TP \fB\-l\fR <\fIfile\fP> log messages to \fIfile\fP instead of standard error output .TP \fB\-u\fR <\fInum\fP> pause \fInum\fP microseconds after each write \- might increase performance on some drives with very low performance (< 1 MB/sec) .TP \fB\-r\fR <\fIrate\fP> Set the maximum read rate to <\fIrate\fP>. <\fIrate\fP> can be given in either Bytes, kBytes, MBytes, or GBytes per second. To do so, use an appropriate suffix (i.e. k,M,G). This option is useful if you have a tape that is capable of transferring data faster than the host can handle it. In this case you can use this option to limit the transfer rate and keep the tape running. Be aware that this is both good for your tape drive, and enhances overall performance, by avoiding tape screwing. .TP \fB\-R\fR <\fIrate\fP> Same as above only for setting the transfer limit for the writer. .TP \fB\-A\fR <\fIcmd\fP> the device used is an autoloader which uses \fIcmd\fP to load the next volume. Pass <\fI/bin/false\fP> as an autoload command to suppress the warning message that appears when run without controlling terminal (e.g. via cron). Like this the autoload will fail and mbuffer will terminate with an error message when reaching the end of the tape. .TP \fB\-a\fR <\fItime\fP> the device used is an autoloader which takes \fItime\fP seconds to load a new tape .TP \fB\-f\fR overwrite output file if it exists already .TP \fB\-c\fR write with synchronous data integrity support \- This option forces all writes to complete before continuing. This enables errors to be reported earlier and more precisely, but might decrease performance. Especially systems with high level of data integrity support suffer a huge performance hit. Others might seem to be unaffected, but just neglect support for full synchronous data integrity. .TP \fB\-v\fR <\fInum\fP> set verbose level to \fInum\fP. Valid values are 0..6 (0 = none, 1 = errors, 2 = warnings, 4 = information messages, 5 = debugging messages, 6 = I/O debugging). Higher values include lower values messages. .TP \fB\-q\fR quiet \- do not display the status on the standard error output .TP \fB\-Q\fR quiet \- do not log the status in the log file .TP \fB\-\-direct\fR Use O_DIRECT to open file descriptors. This option is not available on all systems. It tells the OS to bypass the page cache to improve performance when reading and writing. On Solaris this is an auto-magic option that is enabled if it is supported for the relevant file. Be aware that this option might lead to read/write failures, if the buffer isn't properly aligned for direct I/O. Additionally, open might fail with EINVAL (i.e. invalid argument) if the named file does not support O_DIRECT. .TP \fB\-\-append\fR Open next output file given via option \-o in append mode. .TP \fB\-\-truncate\fR Truncate next output file given via option \-o when opening it. .TP \fB\-6\fR Force IPv6 mode for the following network I/O options on command line. \fB\-4\fR Force IPv4 mode for the following network I/O options on command line. \fB\-0\fR Choose IPv4/IPv6 mode on demand. .TP \fB\-h, \-\-help\fR Output help information and exit. .TP \fB\-H, \-\-md5\fR Generate a MD5 hash of transferred data. .TP \fB\-H, \-\-pid\fR Print PID of current process. This option can help you to figure out which instance of mbuffer to kill, if multiple are running and one is hanging due to a network issue. Printing of the PID can also be triggered by adding "printpid = 1" to your .mbuffer.rc file. .TP \fB\-V, \-\-version\fR Output version information and exit. .TP \fB\-W\fR <\fItimeout\fP> Activates a watchdog that gets triggered every \fItimeout\fP seconds and checks weather I/O activity has stalled. If either channel has stalled for a complete period, the watchdog writes an error message and terminates mbuffer via SIGINT. Be aware that the watchdog is unaware of tape-change activities. So choose the watchdog timeout greater that the worst-case tape-change time. The watchdog is activated with parsing option -W or after parsing all options. To avoid that the watchdog will trigger during network initialization, put the option -W after -I and -O. .SH "DEFAULT VALUES" The default values for following options can be set as \fIkey = value\fP pairs in the ~/.mbuffer.rc file: .br \fIblocksize\fP: block size (option \-s) .br \fItimeout\fP: watchdog timeout (option \-W) .br \fItotalmem\fP: total buffer size (option \-m) .br \fImaxreadspeed\fP: maximum read speed (option \-r) .br \fImaxwritespeed\fP: maximum write speed (option \-R) .br \fIstartwrite\fP: threshold for start writing (option \-P) .br \fIstartread\fP: threshold for start reading (option \-p) .br \fIpause\fP: pause after writing a block (option \-u) .br \fInumblocks\fP: number of blocks in buffer (option \-b) .br \fImemlock\fP: lock buffer in memory (option \-L) .br \fIshowstatus\fP: print transfer status on console (option \-q) .br \fIlogstatus\fP: write transfer status to logfile (option \-Q) .br \fItcpbuffer\fP: TCP buffer size (option \-\-tcpbuffer) .br .SH "ENVIRONMENT VARIABLES" If TMPDIR is set, mbuffer allocates storage for file-based buffers in this directory\&.
