Here is a matrix of mmap possibilities: mmap private not fixed mmap private fixed at somewhere currently unmapped mmap private fixed at somewhere already mapped mmap shared not fixed mmap shared fixed at somewhere currently unmapped mmap shared fixed at somewhere already mapped For private mappings, we should verify that changes cannot be read() back from the file, nor mmap's back from the file at a different address. (There have been systems where private was not correctly implemented like the infamous i386 svr4.0, and systems where the VM page cache was not coherent with the file system buffer cache like early versions of FreeBSD and possibly contemporary NetBSD.) For shared mappings, we should conversely verify that changes get propagated back to all the places they're supposed to be. Grep wants private fixed already mapped.

Then to write the message somewhere meaningful call \fBqb_log_ctl()\fP to configure the targets. .RE .PP Simplist possible use: .PP .nf main() { qb_log_init('simple-log', LOG_DAEMON, LOG_INFO); // ... qb_log(LOG_WARNING, 'watch out'); // ... qb_log_fini(); } .fi .PP .PP \fBConfiguring log targets.\fP.RS 4 A log target can by syslog, stderr, the blackbox or a text file. By default only syslog is enabled. .RE .PP To enable a target do the following .PP .nf qb_log_ctl(QB_LOG_BLACKBOX, QB_LOG_CONF_ENABLED, QB_TRUE); .fi .PP .PP syslog, stderr and the blackbox are static (they don't need to be created, just enabled or disabled. However you can open multiple logfiles (32 - QB_LOG_BLACKBOX). To do this use the following code. .PP .nf mytarget = qb_log_file_open('/var/log/mylogfile'); qb_log_ctl(mytarget, QB_LOG_CONF_ENABLED, QB_TRUE); .fi .PP .PP Once your targets are enabled/opened you can configure them as follows: Configure the size of blackbox .PP .nf qb_log_ctl(QB_LOG_BLACKBOX, QB_LOG_CONF_SIZE, 1024*10); .fi .PP .PP Make logging to file threaded: .PP .nf qb_log_ctl(mytarget, QB_LOG_CONF_THREADED, QB_TRUE); .fi .PP .PP To workaround your syslog daemon filtering all messages > LOG_INFO .PP .nf qb_log_ctl(QB_LOG_SYSLOG, QB_LOG_CONF_PRIORITY_BUMP, LOG_INFO - LOG_DEBUG); .fi .PP .PP To ensure all logs to file targets are fsync'ed (default QB_FALSE) .PP .nf qb_log_ctl(mytarget, QB_LOG_CONF_FILE_SYNC, QB_TRUE); .fi .PP .PP \fBFiltering messages.\fP.RS 4 To have more power over what log messages go to which target you can apply filters to the targets. What happens is the desired callsites have the correct bit set. Then when the log message is generated it gets sent to the targets based on which bit is set in the callsite's 'target' bitmap. Messages can be filtered based on the: .IP "1." 4 filename + priority .IP "2." 4 function name + priority .IP "3." 4 format string + priority .PP .RE .PP So to make all logs from evil_fnunction() go to stderr do the following: .PP .nf qb_log_filter_ctl(QB_LOG_STDERR, QB_LOG_FILTER_ADD, QB_LOG_FILTER_FUNCTION, 'evil_fnunction', LOG_TRACE); .fi .PP .PP So to make all logs from totem* (with a priority <= LOG_INFO) go to stderr do the following: .PP .nf qb_log_filter_ctl(QB_LOG_STDERR, QB_LOG_FILTER_ADD, QB_LOG_FILTER_FILE, 'totem', LOG_INFO); .fi .PP .PP So to make all logs with the substring 'ringbuffer' go to stderr do the following: .PP .nf qb_log_filter_ctl(QB_LOG_STDERR, QB_LOG_FILTER_ADD, QB_LOG_FILTER_FORMAT, 'ringbuffer', LOG_TRACE); .fi .PP .PP \fBThread safe non-blocking logging.\fP.RS 4 Logging is only thread safe when threaded logging is in use. If you plan on logging from multiple threads, you must initialize libqb's logger thread and use qg_log_filter_ctl to set the QB_LOG_CONF_THREADED flag on all the logging targets in use. .RE .PP To achieve non-blocking logging you can use threaded logging as well So any calls to write() or syslog() will not hold up your program. .PP Threaded logging use: .PP .nf main() { qb_log_init('simple-log', LOG_DAEMON, LOG_INFO); qb_log_ctl(QB_LOG_SYSLOG, QB_LOG_CONF_THREADED, QB_TRUE); // ... daemonize(); // call this after you fork() qb_log_thread_start(); // ... qb_log(LOG_WARNING, 'watch out'); // ... qb_log_fini(); } .fi .PP .PP \fBA blackbox for in-field diagnosis.\fP.RS 4 This stores log messages in a ringbuffer so they can be written to file if the program crashes (you will need to catch SIGSEGV). These can then be easily printed out later. .RE .PP \fBNote:\fP .RS 4 the blackbox is not enabled by default. .RE .PP Blackbox usage: .PP .nf static void sigsegv_handler(int sig) { (void)signal (SIGSEGV, SIG_DFL); qb_log_blackbox_write_to_file('simple-log.fdata'); qb_log_fini(); raise(SIGSEGV); } main() { signal(SIGSEGV, sigsegv_handler); qb_log_init('simple-log', LOG_DAEMON, LOG_INFO); qb_log_filter_ctl(QB_LOG_BLACKBOX, QB_LOG_FILTER_ADD, QB_LOG_FILTER_FILE, '*', LOG_DEBUG); qb_log_ctl(QB_LOG_BLACKBOX, QB_LOG_CONF_SIZE, 1024*10); qb_log_ctl(QB_LOG_BLACKBOX, QB_LOG_CONF_ENABLED, QB_TRUE); // ... qb_log(LOG_WARNING, 'watch out'); // ... qb_log_fini(); } .fi .PP .PP \fBTagging messages.\fP.RS 4 You can tag messages using the second argument to \fBqb_logt()\fP or by using \fBqb_log_filter_ctl()\fP. This can be used to add feature or sub-system information to the logs. .RE .PP .PP .nf const char* my_tags_stringify(uint32_t tags) { if (qb_bit_is_set(tags, QB_LOG_TAG_LIBQB_MSG_BIT) { return 'libqb'; } else if (tags == 3) { return 'three'; } else { return 'MAIN'; } } main() { // ... qb_log_tags_stringify_fn_set(my_tags_stringify); qb_log_format_set(QB_LOG_STDERR, '[%5g] %p %b'); // ... qb_logt(LOG_INFO, 3, 'hello');

The following functions can be used to atomically access integers and pointers. They are implemented as inline assembler function on most platforms and use slower fall-backs otherwise. Using them can sometimes save you from using a performance-expensive pthread_mutex to protect the integer or pointer. .PP The most important usage is reference counting. Using \fBqb_atomic_int_inc()\fP and \fBqb_atomic_int_dec_and_test()\fP makes reference counting a very fast operation. .PP You must not directly read integers or pointers concurrently accessed by multiple threads, but use the atomic accessor functions instead. That is, always use \fBqb_atomic_int_get()\fP and \fBqb_atomic_pointer_get()\fP for read outs. They provide the necessary synchonization mechanisms like memory barriers to access memory locations concurrently. .PP If you are using those functions for anything apart from simple reference counting, you should really be aware of the implications of doing that. There are literally thousands of ways to shoot yourself in the foot. So if in doubt, use a pthread_mutex. If you don't know, what memory barriers are, do not use anything but \fBqb_atomic_int_inc()\fP and \fBqb_atomic_int_dec_and_test()\fP. .PP It is not safe to set an integer or pointer just by assigning to it, when it is concurrently accessed by other threads with the following functions. Use \fBqb_atomic_int_compare_and_exchange()\fP or \fBqb_atomic_pointer_compare_and_exchange()\fP respectively. .SH "Define Documentation" .PP .SS "#define qb_atomic_int_dec_and_test(atomic) (qb_atomic_int_exchange_and_add ((atomic), -1) == 1)" .PP Atomically decrements the integer pointed to by atomic by 1. \fBParameters:\fP .RS 4 \fIatomic\fP a pointer to an integer .RE .PP \fBReturns:\fP .RS 4 QB_TRUE if the integer pointed to by atomic is 0 after decrementing it .RE .PP .SS "#define qb_atomic_int_get(atomic) ((int32_t)*(atomic))" .SS "#define qb_atomic_int_inc(atomic) (qb_atomic_int_add ((atomic), 1))" .PP Atomically increments the integer pointed to by atomic by 1. \fBParameters:\fP .RS 4 \fIatomic\fP a pointer to an integer. .RE .PP .SS "#define qb_atomic_int_set(atomic, newval) ((void) (*(atomic) = (newval)))" .SS "#define qb_atomic_pointer_get(atomic) ((void*)*(atomic))" .SS "#define qb_atomic_pointer_set(atomic, newval) ((void*) (*(atomic) = (newval)))" .SH "Function Documentation" .PP .SS "void qb_atomic_init (void)" .SS "void qb_atomic_int_add (volatile int32_t QB_GNUC_MAY_ALIAS * atomic, int32_t val)" .PP Atomically adds val to the integer pointed to by atomic.

A callback used with qb_ipcs_create() is called * for every new ipc connection with the parameters of UID and GID.

Then to write the message * somewhere meaningful call qb_log_ctl() to configure the targets. * * Simplist possible use: * @code * main() { * qb_log_init("simple-log", LOG_DAEMON, LOG_INFO); * // ... * qb_log(LOG_WARNING, "watch out"); * // ... * qb_log_fini(); * } * @endcode * * @par Configuring log targets. * A log target can by syslog, stderr, the blackbox or a text file. * By default only syslog is enabled. * * To enable a target do the following * @code * qb_log_ctl(QB_LOG_BLACKBOX, QB_LOG_CONF_ENABLED, QB_TRUE); * @endcode * * syslog, stderr and the blackbox are static (they don't need * to be created, just enabled or disabled. However you can open multiple * logfiles (32 - QB_LOG_BLACKBOX). To do this use the following code. * @code * mytarget = qb_log_file_open("/var/log/mylogfile"); * qb_log_ctl(mytarget, QB_LOG_CONF_ENABLED, QB_TRUE); * @endcode * * Once your targets are enabled/opened you can configure them as follows: * Configure the size of blackbox * @code * qb_log_ctl(QB_LOG_BLACKBOX, QB_LOG_CONF_SIZE, 1024*10); * @endcode * * Make logging to file threaded: * @code * qb_log_ctl(mytarget, QB_LOG_CONF_THREADED, QB_TRUE); * @endcode * * To workaround your syslog daemon filtering all messages > LOG_INFO * @code * qb_log_ctl(QB_LOG_SYSLOG, QB_LOG_CONF_PRIORITY_BUMP, * LOG_INFO - LOG_DEBUG); * @endcode * * To ensure all logs to file targets are fsync'ed (default QB_FALSE) * @code * qb_log_ctl(mytarget, QB_LOG_CONF_FILE_SYNC, QB_TRUE); * @endcode * * * @par Filtering messages. * To have more power over what log messages go to which target you can apply * filters to the targets. What happens is the desired callsites have the * correct bit set. Then when the log message is generated it gets sent to the * targets based on which bit is set in the callsite's "target" bitmap. * Messages can be filtered based on the: * -# filename + priority * -# function name + priority * -# format string + priority * * So to make all logs from evil_fnunction() go to stderr do the following: * @code * qb_log_filter_ctl(QB_LOG_STDERR, QB_LOG_FILTER_ADD, * QB_LOG_FILTER_FUNCTION, "evil_fnunction", LOG_TRACE); * @endcode * * So to make all logs from totem* (with a priority <= LOG_INFO) go to stderr do the following: * @code * qb_log_filter_ctl(QB_LOG_STDERR, QB_LOG_FILTER_ADD, * QB_LOG_FILTER_FILE, "totem", LOG_INFO); * @endcode * * So to make all logs with the substring "ringbuffer" go to stderr do the following: * @code * qb_log_filter_ctl(QB_LOG_STDERR, QB_LOG_FILTER_ADD, * QB_LOG_FILTER_FORMAT, "ringbuffer", LOG_TRACE); * @endcode * * @par Thread safe non-blocking logging. * Logging is only thread safe when threaded logging is in use. If you plan * on logging from multiple threads, you must initialize libqb's logger thread * and use qg_log_filter_ctl to set the QB_LOG_CONF_THREADED flag on all the * logging targets in use. * * To achieve non-blocking logging you can use threaded logging as well * So any calls to write() or syslog() will not hold up your program. * * Threaded logging use: * @code * main() { * qb_log_init("simple-log", LOG_DAEMON, LOG_INFO); * qb_log_ctl(QB_LOG_SYSLOG, QB_LOG_CONF_THREADED, QB_TRUE); * // ... * daemonize(); * // call this after you fork() * qb_log_thread_start(); * // ... * qb_log(LOG_WARNING, "watch out"); * // ... * qb_log_fini(); * } * @endcode * * @par A blackbox for in-field diagnosis. * This stores log messages in a ringbuffer so they can be written to * file if the program crashes (you will need to catch SIGSEGV). These * can then be easily printed out later. * * @note the blackbox is not enabled by default. * * Blackbox usage: * @code * * static void sigsegv_handler(int sig) * { * (void)signal (SIGSEGV, SIG_DFL); * qb_log_blackbox_write_to_file("simple-log.fdata"); * qb_log_fini(); * raise(SIGSEGV); * } * * main() { * * signal(SIGSEGV, sigsegv_handler); * * qb_log_init("simple-log", LOG_DAEMON, LOG_INFO); * qb_log_filter_ctl(QB_LOG_BLACKBOX, QB_LOG_FILTER_ADD, * QB_LOG_FILTER_FILE, "*", LOG_DEBUG); * qb_log_ctl(QB_LOG_BLACKBOX, QB_LOG_CONF_SIZE, 1024*10); * qb_log_ctl(QB_LOG_BLACKBOX, QB_LOG_CONF_ENABLED, QB_TRUE); * // ... * qb_log(LOG_WARNING, "watch out"); * // ... * qb_log_fini(); * } * @endcode * * @par Tagging messages. * You can tag messages using the second argument to qb_logt() or * by using qb_log_filter_ctl(). * This can be used to add feature or sub-system information to the logs. * * @code * const char* my_tags_stringify(uint32_t tags) { * if (qb_bit_is_set(tags, QB_LOG_TAG_LIBQB_MSG_BIT) { * return "libqb"; * } else if (tags == 3) { * return "three"; * } else { * return "MAIN"; * } * } * main() { * // ... * qb_log_tags_stringify_fn_set(my_tags_stringify); * qb_log_format_set(QB_LOG_STDERR, "[%5g] %p %b"); * // ... * qb_logt(LOG_INFO, 3, "hello"); * qb_logt(LOG_INFO, 0, "hello"); * } * @endcode * The code above will produce: * @code * [libqb] some message * [three] info hello * [MAIN ] info hello * @endcode * * @example simplelog.c */ #undef LOG_TRACE #define LOG_TRACE (LOG_DEBUG + 1) #define QB_LOG_MAX_LEN 512 #define QB_LOG_STRERROR_MAX_LEN 128 typedef const char *(*qb_log_tags_stringify_fn)(uint32_t tags); /** * An instance of this structure is created in a special * ELF section at every dynamic debug callsite.

Quarterback requires a coherent mmap() system call and will not operate on platforms which don't support coherent mmap(). ---------------------------- * Building from git * ---------------------------- When building and installing from subversion, automake 2.61 or later is required. Prior versions will result in build failures. Step 1: check out a copy of the repository git clone git://git.fedoraprojects.org/git/quarterback Find the version you want to build. Usually this will be the "master" branch. If you want to build a specific released version check 'git tag -l'. Step 2: Generate the makefiles balance: ./autogen.sh Step 3: Run the configure script Note that this will install to /usr by default to install to /usr/local use --prefix=/usr/local balance: ./configure Step 4: build balance: make Step 5: Install the binaries balance: sudo make install ------------------------- * Building from tarball * ------------------------- The tarball is distributed with pregenerated makefiles. There is no need to run the autogen.sh script in this case.

Log targets default to showing this extended information but qb_log_ctl() may be used to indicate that the extended information should be stripped instead. The use case is a log message that has some information of value to administrators and other information that is only of value for debugging. Two targets can be configured such that the administrator log is not cluttered with debug information, but a separate debug log is still available with complete information. The magic character is the bell (\a). If someone wants to log an actual bell character, they can do so in the extended information or via a %c format (only the first bell is magic and only in the format string). 2015-04-30 David Vossel Merge pull request #154 from davidvossel/master Low: examples: fix race condition in glib mainloop example 2015-04-29 David Vossel Merge pull request #153 from credativ/hppa-alignment Fix alignment issues on hppa 2015-04-27 Ken Gaillot Low: build: update .gitignore for vim swap files and "make check" output 2015-04-24 David Vossel Low: examples: fix race condition in glib mainloop example 2015-04-24 Helge Deller Fix alignment issues on hppa libqb fails to build on the hppa architecture, because the built-in testcases fail as can be seen here: http://buildd.debian-ports.org/status/fetch.php?pkg=libqb&arch=hppa&ver=0.17.0-2&stamp=1409458262 I did analyzed why they fail, and the reason is that on hppa we have somewhat more complicated requirements (e.g. alignments) which needs to be followed in order to mmap shared pages between processes. It's different than what can be done compared to ia64 and sparc. The attached patch fixes libqb on the hppa architecture and with it all testcases finish successful. By the way, I fixed a small typo in configure.ac too where arm platforms prints "ia64"...

Remove obsolete options from doxyfiles The SYMBOL_CACHE_SIZE, HTML_ALIGN_MEMBERS and USE_INLINE_TREES options were at their default values, so it is safe to remove them now that they only generate warnings.

If one of these epoll sources gains a new event (say, by switching from "readable" to "readable and writeable"), then this new event would be missed. To fix this, merge new epoll events into revents regardless of whether the job is on the joblist. When the job is dispatched, revents will be cleared, or the epoll source will be deleted entirely. ipc_shm: fix error handling in qb_ipcs_shm_connect() The request and response SHM segments were being closed under the wrong labels, and the event SHM segment wasn't being cleaned up at all. ringbuffer: fix size in qb_rb_create_from_file() qb_rb_open() expects the size field to represent the maximum chunk size. It adds QB_RB_CHUNK_MARGIN + 1 and rounds up to the page size to determine the ringbuffer's total size.

Fix: ipcs: Disconnect shm ipc connection when poll socket returns error on msg receive Fix: ipcs: Properly disconnect client connection on POLLNVAL or any other error causing connection removal from mainloop. qb_ipcs_dispatch_connection_request is a callback function registered with mainloop, or whatever other looping thread implementation is in use. When this callback is registered, a reference of the connection object is given to the mainloop thread. If this callback ever returns something none zero the callback (and corresponding fd) is unregistered from the loop automatically, so we must decrement the reference in this instance. Since unregistering this callback from mainloop guarantees a disconnect simply because requests on the fd are no longer processed, it is best that we completely disconnect the connection (which will handle the unref) when this callback returns an error... Otherwise since the fd is unregistered from the mainloop thread, it may not be possible to detect a disconnect in the future. 2013-06-29 David Vossel Simplify internal ipcs ref counting, add comments and document api behavior Simplifies connection ref counting without changing behavior 2013-06-28 David Vossel Low remove ref-count error in example ipcserver.

This means there's a race between when the ipc server side has set up and is listening on the socket, and when the client may connect; if the client connects and sends its first message before the server has set SO_PASSCRED on the socket, then there will be no ucred information associated with the message. The fix is to set SO_PASSCRED on the client socket as well, so that the message will always have a ucred associated with it when the server reads it. Without this change, around 1% of cpg_model_initialize() calls fail with CS_ERR_ACCESS. (This Linux behaviour was introduced just on a year ago in 16e5726269611b71c930054ffe9b858c1cea88eb "af_unix: dont send SCM_CREDENTIALS by default".) ipc_us: clear request unused fields Clear unused request fields and padding so that valgrind doesn't complain about undefined data being sent over the socket. 2012-09-05 Andrew Beekhof TEST: Include writing and reading the blackbox in the log_long_msg test 2012-09-05 Angus Salkeld LOG: fix qb_vsnprintf_deserialize() the strlcat was not call correctly, it needs the original string to find the end and return the correct length. 2012-09-01 Angus Salkeld Merge pull request #41 from jsgf/master Fix some 64-bit big-endian issues 2012-08-31 Jeremy Fitzhardinge blackbox: fix 64-bit big-endian issues Two issues: 1. when writing out the function name length, don't just write the 4 MSB of the size 2. when reading the time, don't just use the 4 MSB of the time as the timestamp; the log contains a full time_t, so we may as well use it. 2012-08-31 Angus Salkeld Remove IPC_NEEDS_RESPONSE_ACK and turn off shm ipc on solaris Define unix path max for openbsd Only turn on ipc_needs_response_ack=yes for solaris Hopefully I can kill this option.

Move to send() instead of sendmsg() as it's easier to track resending partial messages. 2012-05-02 Angus Salkeld IPC: initialize enough shared mem for all 3 one way connections. IPC: keep retrying to recv the socket message if partially recv'ed (part 2) IPC: keep retrying to recv the socket message if partially recv'ed IPC: handle the server shutdown better IPC: handle a connection disconnect from the server better Only problem with SOCKET. 2012-05-01 Angus Salkeld IPC: make it possible to send events in the connected callback. This was only a problem with QB_IPC_SOCKET. Add the event queue length to the connection stats. IPC: add a is_connected client side function. Fix typo in ./check docs: clarify the need to use request/response headers Remove unused local variable 2012-04-30 Angus Salkeld IPC: change the socket recv function to read the response header. It needs to only recv the size of this message, else we recv more than one message and effectively drop messages (hidden at the end of the current message). Add some special commands into the ipc example type "events" and the server will send 10 events. type 'kill' into the client and this will simulate the server dying. TEST: improve the tracing in the ipc tests. 2012-04-30 Andrew Beekhof Make "make (s)rpm" work more reliably Make sure the version number is re-calculated on each run. 2012-04-30 Angus Salkeld TEST: add a test to confirm we get the events we send. TEST: reuse send_and_check for events. 2012-04-29 Angus Salkeld IPC: make it possible for a root client to talk to a non-root server. 2012-04-26 Angus Salkeld Run ./Lindent in the examples directory Add some debug code to the ipcclient example IPC: make sure ipc (socket) clients can connect to a server running as root. 2012-04-23 Angus Salkeld IPC: allow qb to bump the max_message_size I think this is more user friendly. IPC: check for a sane minimum max_message_size add rpl_sem.h loop_poll_int.h to noinst_headers 2012-04-04 Angus Salkeld Handle errors more consistently call recv_ready on socket types Handle a recv of size 0 make bsd shm path better by default. Fix kqueue on freebsd. Get the example socket includes right. 2012-04-03 Angus Salkeld Fix kqueue compiling. POLL: seperate out the poll/epoll and add kqueue 2012-04-03 Jan Friesse Test existence of getpeer* functions Add inet header to tcpclient example Don't link with setpshared if unavailable NetBSD doesn't have semun defined 2012-03-27 Jan Friesse Use MADV_NOSYNC only on systems where available Use SCHED_BATCH only on platforms where available 2012-03-27 Angus Salkeld Fix a bug introduced by the bsd patch. I missed the non-native case. Cleanup the selection of semaphores to use Fix some leaks in the logging. Mainly for valgrind purposes. 2012-03-24 Angus Salkeld Try and improve the portability on bsd variants. Also add a QB_IPC_NATIVE type that selects the best ipc type available. 2012-03-11 The Quarterback Library Release Team Bump the version to 0.11.1 2012-03-09 Angus Salkeld LOOP: remove some old timerfd code. TEST: add a test to check the order of the jobs LOOP: when new jobs are added they are added to the head instead of the tail. We must add new jobs to the tail of the job queue otherwise old jobs will get stuck in the job list. LOG: Now the array is self locking we can make the lookup array dynamic Add locking to the array when growing. IPC: make the _request_q_len_get() function more obvious. IPC: fix multiple receives from qb_ipc_us_recv() So this function is used by the QB_IPC_SOCKET transport and is used like recv(,, max_size_of_my_rx_buf,,); But in the shared mem transport it is used to recv a notification of something in shared mem is available in this case we really want to make sure we recv all the notifications. So I have split these into 2 functions. IPC: make sure that the wrong union member is not written to. Move the connection type into the one_way struct. Seem like a more obvious place for it next to the union. Also it will help prevent issues like in qb_ipc_us_recv() where there is a rather dodgy access of ctl->sent. TIMER: check for null timer handle 2012-03-07 The Quarterback Library Release Team Bump the version to 0.11.0 2012-03-07 Angus Salkeld ARRAY: cleanup the pointer sizeof() LOG: turn off __attribute__(section) for powerpc (not working) TESTS: move the util tests into "slow-tests" (i.e. optional) So this this test is timing sensitive and can easily fail on slow build farm machines. So I have enabled it on the --enable-slow-tests configure option and put this into ./check as the default. TEST: make the test_priority the same type as in the callsite LOG: make the log arrays manually grow-able since we need to lock the calls. RB: fix test failure on ppc 2012-03-06 Angus Salkeld RB: change the name of the size to word_size to be more clear TEST: add some more signal tests. -Make sure we only get one callback per signal -Make sure we correctly delete a callback even if it has been put in the job queue. LOOP: fix deletion of signal handlers when they are pending LOOP: signal handlers were always added as high priority. This now adds them as requested by the user. 2012-03-05 Angus Salkeld TEST: deal with mac's limited sed check: add debugging to the configure options and remove unused options TEST: properly clear the filters LOG: expose the mechanism to get a dynamic callsite. 2012-02-24 Angus Salkeld Revert part of my COARSE grained timer commit The stopwatch and timers use qb_util_nano_current_get() and need to be accurate. This does't seem to effect performance at all so no loss there. Remove timerfd usage and go back to timelist. timefd is using too much cpu and it is using up file descriptors. timelist is also more portable and now I have less code to maintain. UTIL: if possible use COARSE resolution clocks - they are much faster. 2012-02-22 Angus Salkeld ARRAY: save memory (in the bins array) and allow holes in the array LOOP: add qb_loop_timer_is_running() 2012-02-20 Angus Salkeld LOOP: allow stop() and run() to be called with NULL loop instance. LOOP: fix doxygen parameter comment LOG: add stdout target 2012-02-15 Angus Salkeld LOOP: add a function to delete jobs LOG: remove debug printf's LOG: remove an old/incorrect doxygen comment. LOG: add a hostname %H format specifier. This is useful when logging to file on a cluster. LOG: Add qb_log_filter_fn_set() 2012-02-14 The Quarterback Library Release Team Fix "make distcheck" add include path to AM_CPPFLAGS strl* files are built a bit differently and need the global flags Bump the version to 0.10.1 2012-02-14 Angus Salkeld clang: Remove unused code TEST: make the ipc failure test closer to corosync's case. RB: add a debug message if trying to read a message of the wrong size IPC: split up the recv into chuncks of 2 seconds. This is because semaphores can't detect the other side has failed/exited. So we rely on the socket poll to tell us. Be more consistent with the internal logs. 2012-02-10 Angus Salkeld LOOP: make it possible to pass in NULL as the default loop instance 2012-02-08 Angus Salkeld RB: use the proper struct not the typedef in the implementation. RB: Fix potential mem leak Don't mix enums (QB_TRUE/TRUE) use random() not rand() Remove dead code set umask before calling mkstemp() Use safer versions of string functions (strcpy -> strlcpy) Increase the coverity aggressiveness TEST: make the loop ratelimit test more forgiving. 2012-02-07 The Quarterback Library Release Team Bump the lib version to 0.10.0 2012-02-06 Angus Salkeld LOOP: handle errors from the poll function LOOP: make the item type applicable to jobs too. Mainly for diagnostics LOOP: fix the todo calculations. The todo system was sucky as it was calculated in different places in the mainloop and at each level. This was exposed by calls to qb_loop_level_item_del() which decremented the level->todo but not the mainloop one. So now we re-calculate it each time. TEST: check for a single job causing a cpu spin LOOP: prevent jobs from consuming too much cpu. 2012-02-03 Angus Salkeld Get coverity to ignore this warning. "Using uninitialized element of array" Change example code to use fgets instead of gets LOG: pass the result of qb_log_thread_start() back to the user Fix some issues found by clang Add clang-analyzer check 2012-02-01 Angus Salkeld Add a split timer to the stopwatch. This is just a re-work of Steve's sample patch. You set the number of splits and whether they overwrite using qb_util_stopwatch_split_ctl(). 2012-01-31 Angus Salkeld IPC: merge common code into new function This also fixes a regression caused by: 42c92fb675a29bb1ec9f718c17daede82d5de3e2 IPC: better handle a disconnect been called from within connection_created() 2012-01-27 Angus Salkeld IPC: fix scary typo Not sure how this happened IPC: fix server error handling 2012-01-26 The Quarterback Library Release Team TEST: Make sure the generated files have the correct include paths Bump the library version to 0.9.0 2012-01-25 Angus Salkeld PTRIE: refcount the notifier structs This fixes: https://github.com/asalkeld/libqb/issues/29 2012-01-24 Angus Salkeld LOG: make sure qb_log_from_external_source() takes priority into account. Fixes: https://github.com/asalkeld/libqb/issues/28 Deprecate qb_util_set_log_function() And remove uses of it from the test programs 2012-01-23 Angus Salkeld LOG: only bump messages that need it (>info) else all the messages get their priorities distorted LOOP: allow a timer to be created without returning the handle This is if the user does not plan to delete the timer. 2012-01-22 Angus Salkeld IPC: this 1 sec wait is slowing all normal dissconnects down this works just as well with a timeout of 0 2012-01-21 Angus Salkeld IPC: check for the server liveness before disconnecting. if the server is dead then is_connected will cause the resourses to be properly cleaned up. 2012-01-18 Angus Salkeld TESTS: add tests for signal handlers IPC: add a context to the client interface 2012-01-17 Angus Salkeld LOG: make sure the format is checked. In case of log clashes (same file/lineno but in different directories. TEST: make sure qb_log() can be called before init. The log is dropped but it won't crash. 2012-01-16 Angus Salkeld make the pc file auto detect -lrt Add a test to enforce standalone headers and protectors Make all headers self standing So the user does not have to include any required headers. make header protection more consistent. TEST: change the script to .sh and generated c file to auto_ Just to make cleanup easier 2012-01-12 Angus Salkeld IPC: fix resource cleanup if the server dies 2012-01-11 Angus Salkeld ipc test: remove try again hack This was needed because I didn't realise the timeout was broken. (at least this works now) Fix check_ipc.c formatting. 2012-01-09 Angus Salkeld LOG: add %P (pid) as a format option. LOG: add %N (log name) as a format option This will log the name passed into qb_log_init() 2012-01-08 Angus Salkeld UTIL: fix qb_timespec_add_ms() It was overwriting the timespec value instead of add to it. 2012-01-05 Angus Salkeld LOG: make it possible to pass in a NULL filename/function into qb_log_from_external_source() 2012-01-05 The Quarterback Library Release Team Bump the library version. 2012-01-05 Angus Salkeld ipc: make coverity happy. Fix two simple coverity warnings trie: correct the free'ing of node mem Fix ./check -h output map: free unused leaf nodes So if a node has no children and no value or notifier then it is freed. 2012-01-04 Angus Salkeld Allow the array to automatically grow. this makes it a bit friendlier to use, as the user will not have to call qb_array_grow(). map: add some introductory doxygen 2012-01-03 Angus Salkeld IPC: remove fd from poll loop in the disconnect Until now we have been relying on getting a POLLHUP, but under heavy load we seem to get an old poll event that cause a double deref of the connection object. IPC: add a new state to the connection state This to handle disconnecting in a failure state (before the connection has been established. Another aspect to this is we don't want to call connection_destroyed() if we haven't called connection_created(). 2011-12-28 Yunkai Zhang Fixed bug: incorrect array length definition When MAX_BINS is larger than MAX_BIN_ELEMENTS, this bug will cause boudary overflow in qb_array_create function. 2011-12-22 Fabio M. Di Nitto Fix a compile warning on sparc (epoll_create1) The problem is that sys/epoll.h was broken on sparc and alpha for a bunch of glibc releases. glibc has the symbol correctly exported, that's why ./configure finds it, but the header is not always correct. Recent versions of glibc have the correct header, so we simply workaround the broken ones. This fix is only necessary to build with --enable-fatal-warnings, otherwise you simply see a build warning, but there are no runtime issues at any stage. 2011-12-22 Angus Salkeld re-fix qb_strerror_r() in case caller frees buf. 2011-12-22 Fabio M. Di Nitto Fix some sparc test failures. I (Angus) have changed some of Fabio's changes. 2011-12-21 Andrew Beekhof LOG: pass args directly into qb_log_from_external_source() 2011-12-21 Angus Salkeld check: add mac checker Merge some portability changes from the mingw branch Re-add new automake options I like the automake options (and encourage other developers to install the neccessary autotools). Here is a handy script to install the newest autotools into a private directory (if you can't get them pre-packaged). http://people.redhat.com/meyering/autotools-install autotools-install --prefix=$HOME/autotools --skip-check 2011-12-19 Andrew Beekhof Support compilation on Mac OSX 2011-12-19 Angus Salkeld make -rt configurable (not needed on mac) Thanks to Andrew Beekhof fix strerror on non-linux 2011-12-18 Angus Salkeld check: add abi & api to help trie: don't create children array on all nodes (save mem on leaf nodes) map: tweek the tests to better test ptrie trie: convert the trie to a patricia trie (or radix tree) http://en.wikipedia.org/wiki/Radix_tree The point of this is to save memory. examples: add example corosync data to mapnotify.c trie: add a way to get node count and mem usage trie: split trie_lookup into trie_lookup and trie_insert 2011-12-16 Angus Salkeld clean .version .tarball-version 2011-12-13 Angus Salkeld IPC: provide finer grained flowcontrol this will allow the user to control the behaviour better. MAP: add honza's example application. MAP: add a notifier purely to allow the user to free memory. At the moment if you have multiple notifiers it becomes impossible to figure out when it is safe to free the values. This new callback can only be added once and is called once, making it better suited to freeing memory. It is also called after the deleted and replaced notifiers. 2011-12-07 Angus Salkeld Improve the stopwatch doxygen comments. 2011-11-25 Angus Salkeld Fix errors found by api-sanity-autotest map: enforce uniqueness of the notifiers based on (func,key,event,userdata) map: add qb_map_notify_del_2() which includes the userdata. This allows you to match on the same fields that you provided in the add. Now including the userdata. skiplist: add the inserted notification skiplist: implement skiplist_notify_del() Hashtable: fix the ordering of the new/old value in the notification Add tests for hash and skiplist notifications By default don't build in the slow benchlog 2011-11-22 Angus Salkeld check: add abi checking script 2011-11-16 The Quarterback Library Release Team Bump the library version to 0.7.0 2011-11-10 Angus Salkeld LOOP: free up the signal list when qb_loop_destory() is called LOG: improve the removal of filters LOG: clean up mem better when qb_log_fini is called 2011-11-09 Angus Salkeld ARRAY: make sure that num_bins stays below MAX_BINS TEST: add a test that reproduces issue/20 https://github.com/asalkeld/libqb/issues/20 2011-11-08 Angus Salkeld Fix ./check -h output 2011-11-07 Angus Salkeld Lindent formatting changes.

It parse "%llx" format as _long_ other than _long long_. At x86_64 platform, both sizeof(long) and sizeof(long long) is 8, this issue would not be triggered, so we could only catch it at i386. 2011-09-16 Angus Salkeld MAP: pass user_data to the callback correctly 2011-09-15 Angus Salkeld MAP: add a more generic notification system 2011-09-13 Angus Salkeld MAP: add prefix iteration for the trie hashtable: fix the iterator skiplist: fix order of deref skiplist: use ++ and -- operators MAP: improve the storage in the trie TESTS: improve the map tests - add a iterator to test_map_simple() - improve the test output 2011-09-12 Angus Salkeld MAP: add a trie implementation http://en.wikipedia.org/wiki/Trie 2011-09-09 Angus Salkeld LOG: allow large priorities They will be printed as trace, it's mainly to make filtering more flexible LOG: add qb_log_filter_ctl2() so we can filter a range of priorities 2011-09-09 The Quarterback Library Release Team Bump the library version. 2011-09-09 Angus Salkeld LOG: fix QB_LOG_INIT_DATA this is weird, but now it actually works 2011-09-08 Angus Salkeld LOG: add a way of getting the target state This is so we can do the following: for (t = 0; t < QB_LOG_TARGET_MAX; t++) { if (qb_log_ctl(t, QB_LOG_CONF_STATE_GET, 0) == QB_LOG_STATE_ENABLED) { // bla bla } } LOG: support comma seperated lists of file and function filters 2011-09-07 Angus Salkeld map: add iterator that does't use a callback MAP: change the keys from void* to char* I think this is the most common usage and greatly simplifies the api.

With a bigger timeout it passes. 2011-06-26 Angus Salkeld configure: improve arch & os detection output. LOG: fix alignment compiler warning on sparc Revert "LOG: use uint8_t for pointer manipulation" This reverts commit a47ae0b6598f16189d55386ef9a3ad1cad204893. 2011-06-26 Jim Meyering don't let an invalid time stamp provoke a NULL dereference * lib/log_blackbox.c (qb_log_blackbox_print_from_file): Handle localtime failure by printing the long-int representation rather than a strftime-formatted one. 2011-06-23 Angus Salkeld Fix references to README Change README into markdown to look better on github 2011-06-22 Angus Salkeld Change Lindent options to break the procedure type. so change: int foo(void) to int foo(void) LOOP: make the return more consistent in qb_loop_timer_expire_time_get() If there is any error return 0 (meaning the timer is or has expired) 2011-06-21 Angus Salkeld LOG: use uint8_t for pointer manipulation char changes size on different arches. 2011-06-20 Angus Salkeld IPC: use the correct pointer type.

This because the system might have CONFIG_HUGETLB_PAGE_SIZE defined in their kernel. So even though sysconf() returns 2K or 4K some arch's mmap() require alignment on these boundaries. TEST: some improvements to the check script to make it's output better. It quietens the output and this makes it easier to understand the results. TEST: Fix ssize_t format compiler warning Make building a bit quieter by default. Fix "make dist". The deps were not quite right with write_logs.c Fix some spelling. 2011-05-31 Angus Salkeld TEST: remove failed server tests. They now fail (because of 8880465924ce090365ee6b87c4d0c167c7deeb62). We now need a smart way of detecting that a process is the last one attached to the ringbuffer and free it. TEST: initialize some globals before the test is run. This is not strictly needed as each test is forked, but is a bit more explicit. TEST: fix the server shutdown. The server was getting prematurently killed, and was causing resource leakage. We now give the server a little time to respond to the connection beiong closed. TEST: add job_add poll_handler TEST: name the ipc connections after the test functions IPC: misc cleanup & logging improvements IPC: make the setting the flowcontrol atomic 2011-05-30 Виноградов Василий RB: More consistent behavior when closing a ringbuffer 2011-05-27 Виноградов Василий Provide some helpful macros for iterating over lists. 2011-05-27 Angus Salkeld TEST: make the creation of write_logs.c atomic 2011-05-26 Angus Salkeld TEST: make sure make-log-test appends a bracket Correct the declarations of some inlines Add support for ansi inline and typeof Remove all the C++ comments Add an ansi option into ./check Also included in ./check all 2011-05-24 Jim Meyering qb_rb_write_to_file clean-up * lib/ringbuffer.c (qb_rb_write_to_file): Remove dead initialization and redundant "result < 0" tests. adjust .gitignore so "git status" ignores all build artifacts use latest git-version-gen from gnulib 2011-05-23 Angus Salkeld LOG: add custom targets This is partly to make the tests more robusts and to add some more flexibility to the logging. 2011-05-20 Angus Salkeld COV 15: fix potential reference after deref COV 14: fix potential dereference after free() COV 13: cleanup error handling in qb_util_circular_mmap() COV 12: prevent unintialized value error in bmcpt COV 10: fix mem leaks in qb_rb_create_from_file() COV 9: fix mem leak in qb_rb_open error condition COV 8: don't leak mem when returning an error.

Fix the test dependancies (and "make rpm") My first attempt at this broke "make rpm" - oops. It seems that we need a common extension for tests to get the dependancies to work. fix the FIXME's Jim pointed out 2011-05-17 Jim Meyering avoid autoconf warning Autoconf warned about this: configure.ac:72: warning: AC_LANG_CONFTEST: no AC_LANG_SOURCE\ call detected in body That's warning about the use via AC_COMPILE_IFELSE without specifying a language. The easiest way to work around that is to avoid the use of CC altogether and instead to use the preprocessor. * configure.ac (cc_supports_flag): Use AC_PREPROC_IFELSE in place of AC_COMPILE_IFELSE (and CPPFLAGS in place of CFLAGS). 2011-05-17 Jim Meyering add FIXME comments for other NULL-deref-upon-OOM problems * lib/ipc_us.c (handle_new_connection): * lib/loop_job.c (qb_loop_jobs_create): * lib/loop_poll.c (qb_loop_poll_create): * lib/loop_timerlist.c (qb_loop_timer_create): * lib/ringbuffer.c (qb_rb_open): * lib/ipcc.c (qb_ipcc_connect): Likewise. avoid NULL dereference after failed malloc * lib/util.c (qb_thread_lock_create): Handle failed malloc. * lib/ipc_posix_mq.c (qb_ipc_pmq_sendv): Likewise. * lib/loop_job.c (qb_loop_job_add): Likewise. * lib/loop.c (qb_loop_create): Likewise. 2011-05-17 Angus Salkeld make sure check_resources is the last test to run http://www.gnu.org/s/hello/manual/automake/Simple-Tests-using-parallel_002dtests.html 2011-05-17 Jim Meyering make the tests run in parallel I ran "make check" in libqb and watched impatiently ;-) as the tests ran in serial on my multi-core system. If you add automake's "parallel-tests" option below, they'll run in parallel. The color-tests option makes it so the "PASS" and "FAIL" words are colored green and red respectively. Nice, but no big deal. Similarly nice-to-have is the "dist-xz" option. That makes is so when you run "make dist" it creates xz-compressed tarballs in addition to the usual gzip-compressed ones. The advantage of also using xz is that it compresses significantly better: $ du -sh *z 1.2M libqb-0.4.1.75-3737-dirty.tar.gz 812K libqb-0.4.1.75-3737-dirty.tar.xz Now, whenever a project releases both gzip-compressed and xz-compressed tarballs, I always download only the latter, smaller ones. Not only does it save time on the download (minimal in this case), but it occupies less space on disk and uncompresses faster. 2011-05-13 Angus Salkeld LOG: strip the last "\n" from incomming messages LOG: make the "entering" and "leaving" capital 2011-05-06 Angus Salkeld Fix some compiler warnings LOG: add an enter and leave trace function 2011-04-18 Angus Salkeld LOG: add locking & change dcs list into a singly-linked list. TESTS: add a threaded logging test LOG: check prioritynames[] bounds LOG: created array with wrong size - yikes! LOG: include needed stdio.h LOG: make all priorities uint8_t 2011-04-15 Angus Salkeld LOG: fix logging to file qb_log_file_open() left the target in an UNUSED state. Compile on FreeBSD Also re-run autoscan. 2011-04-14 Angus Salkeld Add write_logs.c to .gitignore LOG: refactor the filter code a bit. Reuse code a bit better. Add qbconfig.h to the list of headers to be installed. LOG: fix new callsite pointer (not incrementing correctly) TEST: make a way of testing both with and without __attribute__((section)) LOG: fix the building of write_logs.c (for bench-log) LOG: fix formatting test (fails in make distcheck) This fails as the BUILDING_IN_PLACE patch was left out. Now re-added, make distcheck passes. TESTS: use new logging API LOG: add some basic tests & fixes LOG: add dynamic callsites (for platforms that don't support __attribute__(section) ARRAY: add getter's to retrieve number of bins and elms/bin 2011-04-13 Angus Salkeld ARRAY: return -ERANGE when index is out of range. So you can differentiate the other errors (-EINVAL) 2011-04-12 Angus Salkeld LOG: add LOG_TRACE LOG: add the ability to adjust the priority sent to syslog() If you have: qb_log_filter_ctl(QB_LOG_SYSLOG, QB_LOG_FILTER_ADD, QB_LOG_FILTER_FILE, "hack.c", LOG_DEBUG); these logs will not make there way to /var/log/messags without reconfiguring syslog. So to help on the fly debugging do the following: qb_log_ctl(QB_LOG_SYSLOG, QB_LOG_CONF_PRIORITY_BUMP, LOG_INFO - LOG_DEBUG); Now all messages that have the QB_LOG_SYSLOG target set will have their priority bumped before going to syslog(). 2011-04-09 Angus Salkeld Fix the copyright in bench-log.c LOG: flush output to files LOG: change the target type from uint32_t to int32_t. This is so that you won't get warnings from mixing integer types. I have updated the input checks in log.c to check for invalid targets. LOG: only set state in log.c This requires an enable after qb_log_file_open() 2011-04-06 Angus Salkeld LOG: fix splint warning LOG: teach filter_ctl() to write tags LOG: remove the tags arument from qb_log() and add qb_logt() which has the tags argument. I think in most cases tags will not be used and it will just be a pain inserting ", 0". But if someone wants to use tags like this then they still can via qb_logt() LOG: change the filter matches to use strstr() for partial match support. LOG: fix shared library callsites This finds all the callsites in shared libraries (using dl_iterate_phdr()) at the time qb_log_init() is called. Conflicts: lib/log.c LOG: add a callsite_dump() function to see what callsite are avaliable. LOG: support dynamically loaded modules LOG: make prioritynames[] static 2011-04-04 Angus Salkeld Add required include to qbloop.h Merge branch 'logging' 2011-04-01 Angus Salkeld LOG: make the documentation more meaningful LOG: general cleanup (indentation, NULL checks, etc...) LOG: move formatting code into new file Add D_FORTIFY_SOURCE=2 to check script LOG: add a qb_log_fini() to cleanup This replaces qb_log_thread_stop() but also release shared mem 2011-03-31 Angus Salkeld LOG: fix mapping from priority to name Remove qb_log_priority_name_get() as we have the formatting. LOG: add a new "tags" field this is a tags that is used by the caller to: - define the message as an external message (needs free'ing) - define a feature or susbsytem that can be printed in the log message. LOG: change "tags" field to "targets" This is it's new meaning, so makes things clearer LOG: keep a list of active targets to speed iteration LOG: deal better with timestamps 1) use gettimeofday() - suprisingly faster than clock_gettime(MONOTONIC) 2) don't format the time until it is needed 3) insert time_t into the blackbox (not a formatted string) This improves performance and tidies the code up. It also requires less space in the blackbox. LOG: add bench-log to .gitignore 2011-03-31 Steven Dake Add a benchmark program for the qblog flight recorder 2011-03-31 Angus Salkeld LOG: fix minor compile warning 2011-03-30 Angus Salkeld LOG: add a format option to each target. LOG: improve the docs LOG: add qb_log_file_close() LOG: add the ability to import logs from other sources. Be more consistent with the C++ protection Ignore 2 splint warnings SPEC: make the spec file more like the fedora one. LOG: re-work the API to be easier to use. 2011-03-28 Angus Salkeld Add some content to the README LOG: add qb_log_priority_name_get() LOG: fix make install and distcheck LOG: add a qb_perror() function - Add an internal version too - Update the library code to use it. 2011-03-27 Angus Salkeld LOG: add a timestamp to the log handler This makes sure that the timestamp is correct at the time the call to qb_log() was called. TESTS: remove unused function LOG: split the tag function out into tag and untag LOG: improve the doxygen overview. LOG: fix splint warnings 2011-03-26 Angus Salkeld LOG: use the new logging mechanism for internal log messages. This uses the top bit of the "tags" to distinguish the internal messages from extternal ones. 2011-03-25 Angus Salkeld LOG: add a blackbox LOG: add threaded logging (non-blocking) LOG: create a common header Add logging infrastructure. 2011-01-31 The Quarterback Library Release Team Set the gpgsignkey in release.mk Bump library version to 0.4.1 2011-01-31 Angus Salkeld BUILD: only set -g and -O options if explicitly requested. compiler debug & optimization flags are only set with either --enable-debug or --enable-coverage. This prevents defaults and environmental flags from been overridden. Move check_all into check and impove it (add rpm checks) RPM: make the spec more like a fedora spec file fix tarball url add procps to BuildRequires add a "make check" section change %(buildroot) to $RPM_BUILD_ROOT 2011-01-09 Angus Salkeld LOOP: check read() return value DOCS: add missing @param on new timeout argument Remove unneccessary check for library "dl" RPM: add missing build dependancies BUILD: improve the rpm building copy corosync's rpm build system. 2011-01-05 The Quarterback Library Release Team Bump version to 0.4.0 2011-01-04 Angus Salkeld LOOP: change timer handle from pointer to index + check. This changes the timer hande from a live pointer to a handle more like hdb handles (minus the ref counting). What i like about this is it is not neccessary to clear the applications handle using memset(). LOOP: remove tlist absolute timer 2010-12-21 Angus Salkeld TESTS: make sure timers are not leaking file descriptors LOOP: make static functions like __() LOOP: reduce the number of for loops LOOP: change entry type enum This to avoid QB_POLL been equal to 0, which could hide some bugs. LOOP: add per-level todo counters 2010-12-16 Angus Salkeld IPC: use rb refcount to check for "connectiveness" This makes it possible the detect the loss of the server and return -ENOTCONN. RB: add a function to get the reference count. Really handy to see if the peer is "connected". TEST: add ipc tests for recv's with a timeout IPC: add a timeout to the client recv functions Also allow the ringbuffer to pass ETIMEDOUT back to the client applications. 2010-12-14 Angus Salkeld IPC: improve shm performance by timing out earlier on poll() My receint change adding in a call to recv_ready(, 10) was really slowing down the shm performance. So now I am rather retrying which doesn't slow it down and also passes "make check". IPC: return the correct number of bytes sent 2010-12-13 Angus Salkeld IPC: rename _ref_inc() to _ref() DOCS: set the version from a configure variable LOOP: change timers to be nano second based 2010-12-12 Angus Salkeld DOCS: fix some doxygen warnings for missing comments. 2010-12-10 Angus Salkeld IPC: return EAGAIN from qb_ipcc_recv() if recv_ready() returns 0 found with corosync CTS IPC: return -ENOTCONN when the other end exits TESTS: add a test case for recving from a failed server 2010-12-09 Angus Salkeld Remove carriage returns in qb_util_log() calls. IPC: check for null ringbuffer IPC: fix non-blocking event mechanism LOOP: remove unneccessary event array 2010-12-03 Angus Salkeld IPCS: don't block on sending socket notification IPC: export qb_ipcs_disconnect() 2010-11-16 Angus Salkeld fix waring produced by -Wp,-D_FORTIFY_SOURCE=2 Fix some freeBSD compile warnings. LOOP: fix compile warning when we don't have timerfd. LOOP: move pipe creation into qb_loop_signals_create() Also make sure the pipe is non blocking. RB: fix munmap size (else shared mem not freed correctly) Fix some error handling in RB & IPC 2010-11-15 Angus Salkeld IPC: remove try again log message LOOP: prevent timers from deleting them selves. 2010-11-12 Angus Salkeld LOOP: add some debug to log slow jobs IPC: withdraw server socket when destroying a service. TLIST: use qb_util_nano_monotonic_hz() instead of HZ also add a test for under running. RB: check for NULL on close this just saves the user from doing this. UTIL: check for shm usable space. - port corosync write() check 2010-11-09 Angus Salkeld LOOP: add signal support to main loop 2010-11-04 Angus Salkeld LOOP: prevent high cpu utilization on no load. We we passing "0" timeout into poll(). 2010-11-03 Angus Salkeld IPC: add connection_closed() callback. - added another callback closed() and use this as the current destroyed_connection() has been used. - the destroyed() event changes meaning to "the connection object is about to be free'ed" and the user can free the context memory. IPC: change service instance from handle to pointer. Mainly to be consistent with the other objects. Also: - splint warnings(-weak) are now zero. - Added a reference counter to replace the handle. Fix ./check_all - Spelling error in "make distcheck" - add check_resources.sh to EXTRA_DIST 2010-11-02 Angus Salkeld IPC: add flow control & q_len to unix socket transport. This uses a small (2*int32_t) shared memory segment. RB: don't be so timid on shutdown TEST: add a check_resources script 2010-11-01 Angus Salkeld Cleanup config defines & add a check_all script Run: ./check_all to build with and without some common configurations. 2010-10-31 Angus Salkeld UTIL: move mmap helpers into private header LOOP: add support for timerfd If available use timerfd_create() as it is much more accurate than tlist.h 2010-10-30 Angus Salkeld IPC: remove refcount'ing debug TEST: make test ouput more verbose LOOP: add qb_loop_destroy() 2010-10-29 Angus Salkeld LOOP: fix job poll and simplify main loop 2010-10-27 Angus Salkeld IPC: add server connection states for better shutdown. This also fixes the refcounting, which was not quite right. IPC: add qb_ipcs_response_sendv() iovec friendly response function TIME: move tlist_nano_ functions into util RB: improve debug message IPC: add job_add() API to the poll abstraction. 2010-10-22 Angus Salkeld Fix or ignore splint errors fix some build issues on FreeBSD 2010-10-21 Angus Salkeld IPC: add a connection iterator. So we can iterate over all connections on a service. IPC: add stats to server end. 2010-10-20 Angus Salkeld TEST: add glib mainloop option to bms Note: glib is only linked into the test app, so libqb not dependant on glib. This is just testing integration. ATOMIC: fix the memory barrier setup. This was horribly broken. 2010-10-19 Angus Salkeld IPC: remove sprintf where possible LINT: get the lint target working. TEST: add some more array tests. 2010-10-19 The Quarterback Library Release Team Bump version to 0.3.0 2010-10-19 Angus Salkeld Fix the current warnings Add missing qbutil.h HDB: remove locks and use atomic. 2010-10-18 Angus Salkeld HDB: use qb_array. DOCS: add some doxygen comments to array & hdb. RB: fix the sem init logic (always use some semaphore). RB: use the semaphore to return chunks_used. RB: remove locking from ringbuffer. make ref_count atomic RB: prevent fd's from been leaked IPC/RB: name the ringbuffer's files better. IPC: get bmcpt working LOOP: use qbarray for poll_entries. This fixes an issue where removing or adding entries can cause a realloc() to move the entries and then a qb_list_del() causes a SIGSEGV (next pointer is now invalid). qbarray does not use realloc() so does not suffer from this. Add a resizable array that doesn't move memory. ATOMIC: fix make distcheck LIST/LOOP: allow empty list items but don't splice an empty head. IPC: use atomic for ref counting. Add atomic operations. This was initially copied from glib. How ever I have simplified it to only support proper atomic operations with gcc builtin __sync calls. The backup is pthread_spin_lock(). I have also obviously namespaced the code to qb_. 2010-10-18 The Quarterback Library Release Team Tweek the release.mk file to produce tags like vX.Y.Z Bump version to 0.2.0 2010-10-17 Angus Salkeld DOCS: do some work on the doxygen output. IPC: add support for unix sockets 2010-10-16 Angus Salkeld TEST: add support events into bm[cs] LOOP: remove warning. LIST: fix logic in qb_list_splice() this fixes "make check" 2010-10-14 Steven Dake get_more_jobs: use qb_list_splice instead of iterating list and readding oprofile picked up get_more_jobs as a heavy abuser of cpu cycles when running with cpgbench. Typical cpgbench runs this function 37 million times. This small optimization improves performance of corosync as well as reduces cpu utilization used by this function. Might look at tracking length of wait_head and job_head to avoid use of qb_list_length as well (which also iterates). qb_list_splice: don't splice an empty list An empty list passed to splice will damage the target splice list. This patch prevents that from happening by checking for an empty list and not merging in that case. 2010-10-14 Angus Salkeld configure: re-add check for pthread_spin_lock 2010-10-13 Angus Salkeld IPC: remove flow control API and move functionality into send() There is no point in a separate API. IPC: add q_len_get() to posix_mq & sysv_mq IPC: move destroy() into ipcs.c (all were duplicated) IPC: add qb_ipcc_sendv_recv() convenience function. 2010-10-12 Angus Salkeld TEST: make the bmc messages like cpgbench IPC: recv the messages available (not just one) fix some valgrind warnings RB: return EAGAIN not ENOMEM if no space on the rb. IPC: add support for flowcontrol & rate limiting RB: add support for shared user data. (I need this for flow control) IPC: cleanup some formatting. IPC: improve send/recv error handling IPC: accelerate process when rate_limit == FAST. IPC: get the poll independent functions working. IPC: make msg_process return type int IPC: add peek & reclaim Remove timer.c (rather use mainloop) LOOP: add epoll support Add a priority based main loop. This is to try and get a better balance in the amount of processing between IPC and totem in corosync. IPC: remove qb_ipcc_event_release() LIST: add some more convenience macros. 2010-10-06 Angus Salkeld RB: cleanup return codes frpm rb_peek() IPC: make events always use socket notification IPC: use poll() to prevent a recv() blocking IPC: teach event_recv() to take a timeout UTIL: add qb_timespec_add_ms() add X milli seconds to a timespec. add time defines to qbdefs.h IPC: improve resource cleanup/shutdown IPC: make internal message ids negative. IPC: add a user context_get/set() functions. IPC: add sendv() functions to handle iovecs. IPC: make sure FD_CLOEXEC is set on all sockets TEST: disable posix mq test for now. SPEC: Fix the rpm spec file DOCS: quiten the doxygen make process 2010-10-04 Angus Salkeld add qbdefs.h with some common defines. 2010-10-02 Angus Salkeld POLL: add missing fuction. IPC: add a service_id and merge qb_ipcs_create() + qb_ipcs_service_handlers_set() 2010-10-01 Angus Salkeld IPC: change the ipcs_connection to a pointer (not handle). This is make integrating with corosync easier. Also technically it doesn't really matter it still has a reference counter. IPC: make authenticate callback more generic "accept". This is so that it is more obvious that you can use it for authentication, service availabilty and process resource constraints. LIST: add required header POLL: gracefully handle running out of file descriptors. POLL: Allow modifying POLLIN/POLLOUT state in another thread. while the main thread is blocked in poll system call. (ported from corosync) Author: Steven Dake 2010-09-30 Angus Salkeld cleanup the configure script. Remove (now) unused checks. TEST: fix ipc test after receint API changes. Delete unchecked API (to be re-added later). IPC: new auth improvement and limits work around. Create the queues/ringbuffers on the server so we don't have to modify proc entries. Then chown them so that the clients can access them. RB: add qb_rb_chown() change the ownership of the two mmap'ed files. 2010-09-29 Angus Salkeld IPC_SYSV: get sysv ipc to work with non-root processes. TEST: add IPC_TYPE cli option to bms TEST: make bmc's output comma delimited IPC: pack sysv messages into multiple queue items IPC: add events back (were dispatch messages in corosync) IPC: rename dispatch queues to event queues. IPC: rename qb_ipcs_connection_pt -> qb_ipcs_connection_handle_t IPC: un-const the data pointer in recv() POLL: check for stop_requested before poll() as well. 2010-09-07 Angus Salkeld IPC: get shm & pmq working Note: pmq needs "sudo make check" 2010-09-06 Angus Salkeld IPC: add a basic tx/rx test case. - cleanup some printf's IPC: linux & bsd mq_open returns a poll'able file descriptor. Lindent most c files again. IPC: fix crash on failed auth Define new return status policy Good >= 0 (0 = good, or positive value) Bad < 0 (-errno) 2010-09-03 Angus Salkeld BSD: port new changes to BSD - check for doxygen - no RLIMIT_MSGQUEUE on bsd - change ENODATA to ENOMSG 2010-08-23 Angus Salkeld IPC: rewrite (simpler API & more structured layout). - implement using posix message queues - implement using sys-v message queues - implement shared memory ringbuffers - add auth via unix sockets - add items to the TODO This is still a bit rough, more work to follow... 2010-08-22 Angus Salkeld automake: check for more headers 2010-08-09 Angus Salkeld RB: add function qb_rb_chunks_used() This is to make it easier to to see if there is a chunk available to be read. 2010-07-28 Angus Salkeld RB: make the timedwait() functions more consistent POLL: add a job API to process non-fd items. 2010-07-12 quarterback Add a release makefile Originally from here: http://git.fedorahosted.org/git/?p=cluster.git;a=blob_plain;f=make/release.mk;hb=refs/heads/STABLE3 Author: Fabio M. Di Nitto 2010-07-06 Angus Salkeld Add the coding style definition file. 2010-06-22 Angus Salkeld int -> int32_t unsigned int -> uint32_t some to int32_t (bugs) unsigned long long -> uint64_t change name of ringbuffer.h to ringbuffer_int.h 2010-06-16 Angus Salkeld list: rename QB_DECLARE_LIST_INIT -> QB_LIST_DECLARE hdb: move functions into cfile convert int -> int32_t rename qb_hdb_handle_t -> qb_handle_t rename DECLARE_HDB_DATABASE -> QB_HDB_DECLARE rename qb_hdb_handle_database -> qb_hdb 2010-06-15 Angus Salkeld ipc: convert int -> int32_t; unsigned int -> uint32_t ipc: use a ringbuffer for requests. ipcc: remove unneccessry goto rb: fix handling of EINTR from sem_wait rb: make rb_chunk_peek() wait on the sem like chunk_read() rb: fix bit flag numbering 2010-06-12 Angus Salkeld bm test programs: allow no args rb: add a get name function list: add some more doxygen comments rb: add an example to the doxygen description. rb: rename qb_rb_chunk_writable* -> qb_rb_chunk_ check_hash: test for dict/words before running. 2010-06-11 Angus Salkeld rb: cleanup of names and log messages util: move some handy macros into qbuil.h rb: organise the locks/sems a bit better Bring some changes across from corosync. My coverity fixes and honzas fixes. 2010-06-10 Angus Salkeld Remove unneccessary extern's. http://gcc.gnu.org/ml/gcc/2009-04/msg00812.html http://publications.gbdirect.co.uk/c_book/chapter4/linkage.html http://www.eskimo.com/~scs/cclass/notes/sx5b.html note in ipcs.c qb_ipcs_ipc_init() is extern'ed, I don't think that this is needed - we'll soon see :) Format all files with Lindent Add a script for indenting the code (kernel formatting) Add a ringbuffer based off the one in logsys. This ringbuffer is usable across processes. the point is to use this for IPC to provide async connections from client to server, but with inherient flow control. This still needs a bit of clean up, but committing now for feedback and as it is quite functional. 2010-05-31 Angus Salkeld man: document qblist.h better. Fix the installation of libqb.pc Comment out the plugin tests as they break "make rpm" I can't figure out a "nice" way of doing this. 2010-05-27 Angus Salkeld Roll all little libs into libqb. This really makes things simpler (to produce and use). 2010-05-26 Angus Salkeld Make docs rules more maintainable Add pkg-config files. Fix the new inter-library dependancy. http://old.nabble.com/relinking-error-td27796838.html 2010-05-25 Angus Salkeld Add __cplusplus externs Fix make doxygen (for html output) Fix manpage generation when builddir != srcdir use new interanl logging functions Add a library logging function. Add a util library with locking wrappers. 2010-05-24 Angus Salkeld Re-license to LGPL 2.1 2010-04-29 Angus Salkeld fix "make distcheck" I am sure that I am going to learn one day :( Add tezt programs to .gitignore ipc: add non-blocking options to the bmc & bms apps so to test blocking IPC bmc bms to test non-blocking IPC bmc -n bms -n Conflicts: tests/bmc.c ipc: add a non-blocking send function. ipc: add Steve's benchmark test programs ipc: add common types to qbipc_common.h ipc: remove uneccessary version compatibilty 2010-04-16 Angus Salkeld check_plugin: Add -rdynamic to check program check_hash: fix test must be run in one test case. hash: improve the error handling in key_set() 2010-04-15 Angus Salkeld libtool and code re-structure add a unit test for hash & cleanup. Fix make distcheck Add qbhash.h to the makefiles Fix make rpm. Make sure the makefiles are generatd for hash 2010-04-14 Steven Dake Add an initial implementation of a hash table. The hash table implementation is somewhat unique in that I plan to add graph functionality to allow hash entries to be linked between other hash entries to provide a mechanism to structure data within a hash table. 2010-03-20 Angus Salkeld add logsys from corosync. Add wthread & queue. 2010-03-19 Angus Salkeld add ipcs from corosync clean up lib.versions files Add ipcc from corosync tweek the .gitignore add the plugin library. tsafe: replace _XOPEN_SOURCE with HAVE_(function) remove ipc so from makefiles Added qb_ prefix onto public functions/types. Add timer. Add spec file 2010-03-11 Angus Salkeld Add poll, list & tlist Add handle database.

In other projects, it is set to # `$srcdir', `$srcdir/..', or `$srcdir/../..'. # # Of course, Automake must honor this variable whenever it calls a # tool from the auxiliary directory. The problem is that $srcdir (and # therefore $ac_aux_dir as well) can be either absolute or relative, # depending on how configure is run. This is pretty annoying, since # it makes $ac_aux_dir quite unusable in subdirectories: in the top # source directory, any form will work fine, but in subdirectories a # relative path needs to be adjusted first. # # $ac_aux_dir/missing # fails when called from a subdirectory if $ac_aux_dir is relative # $top_srcdir/$ac_aux_dir/missing # fails if $ac_aux_dir is absolute, # fails when called from a subdirectory in a VPATH build with # a relative $ac_aux_dir # # The reason of the latter failure is that $top_srcdir and $ac_aux_dir # are both prefixed by $srcdir. In an in-source build this is usually # harmless because $srcdir is `.', but things will broke when you # start a VPATH build or use an absolute $srcdir. # # So we could use something similar to $top_srcdir/$ac_aux_dir/missing, # iff we strip the leading $srcdir from $ac_aux_dir. That would be: # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"` # and then we would define $MISSING as # MISSING="\${SHELL} $am_aux_dir/missing" # This will work as long as MISSING is not called from configure, because # unfortunately $(top_srcdir) has no meaning in configure. # However there are other variables, like CC, which are often used in # configure, and could therefore not use this "fixed" $ac_aux_dir. # # Another solution, used here, is to always expand $ac_aux_dir to an # absolute PATH.

[This is the first released version of the Lesser GPL. It also counts as the successor of the GNU Library Public License, version 2, hence the version number 2.1.] Preamble The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public Licenses are intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This license, the Lesser General Public License, applies to some specially designated software packages--typically libraries--of the Free Software Foundation and other authors who decide to use it. You can use it too, but we suggest you first think carefully about whether this license or the ordinary General Public License is the better strategy to use in any particular case, based on the explanations below. When we speak of free software, we are referring to freedom of use, 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 this service if you wish); that you receive source code or can get it if you want it; that you can change the software and use pieces of it in new free programs; and that you are informed that you can do these things. To protect your rights, we need to make restrictions that forbid distributors to deny you these rights or to ask you to surrender these rights. These restrictions translate to certain responsibilities for you if you distribute copies of the library or if you modify it. For example, if you distribute copies of the library, whether gratis or for a fee, you must give the recipients all the rights that we gave you. You must make sure that they, too, receive or can get the source code. If you link other code with the library, you must provide complete object files to the recipients, so that they can relink them with the library after making changes to the library and recompiling it. And you must show them these terms so they know their rights. We protect your rights with a two-step method: (1) we copyright the library, and (2) we offer you this license, which gives you legal permission to copy, distribute and/or modify the library. To protect each distributor, we want to make it very clear that there is no warranty for the free library. Also, if the library is modified by someone else and passed on, the recipients should know that what they have is not the original version, so that the original author's reputation will not be affected by problems that might be introduced by others. Finally, software patents pose a constant threat to the existence of any free program. We wish to make sure that a company cannot effectively restrict the users of a free program by obtaining a restrictive license from a patent holder. Therefore, we insist that any patent license obtained for a version of the library must be consistent with the full freedom of use specified in this license. Most GNU software, including some libraries, is covered by the ordinary GNU General Public License. This license, the GNU Lesser General Public License, applies to certain designated libraries, and is quite different from the ordinary General Public License. We use this license for certain libraries in order to permit linking those libraries into non-free programs. When a program is linked with a library, whether statically or using a shared library, the combination of the two is legally speaking a combined work, a derivative of the original library. The ordinary General Public License therefore permits such linking only if the entire combination fits its criteria of freedom. The Lesser General Public License permits more lax criteria for linking other code with the library. We call this license the "Lesser" General Public License because it does Less to protect the user's freedom than the ordinary General Public License. It also provides other free software developers Less of an advantage over competing non-free programs. These disadvantages are the reason we use the ordinary General Public License for many libraries. However, the Lesser license provides advantages in certain special circumstances. For example, on rare occasions, there may be a special need to encourage the widest possible use of a certain library, so that it becomes a de-facto standard. To achieve this, non-free programs must be allowed to use the library. A more frequent case is that a free library does the same job as widely used non-free libraries. In this case, there is little to gain by limiting the free library to free software only, so we use the Lesser General Public License. In other cases, permission to use a particular library in non-free programs enables a greater number of people to use a large body of free software. For example, permission to use the GNU C Library in non-free programs enables many more people to use the whole GNU operating system, as well as its variant, the GNU/Linux operating system. Although the Lesser General Public License is Less protective of the users' freedom, it does ensure that the user of a program that is linked with the Library has the freedom and the wherewithal to run that program using a modified version of the Library. The precise terms and conditions for copying, distribution and modification follow. Pay close attention to the difference between a "work based on the library" and a "work that uses the library". The former contains code derived from the library, whereas the latter must be combined with the library in order to run. GNU LESSER GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 0. This License Agreement applies to any software library or other program which contains a notice placed by the copyright holder or other authorized party saying it may be distributed under the terms of this Lesser General Public License (also called "this License"). Each licensee is addressed as "you". A "library" means a collection of software functions and/or data prepared so as to be conveniently linked with application programs (which use some of those functions and data) to form executables. The "Library", below, refers to any such software library or work which has been distributed under these terms. A "work based on the Library" means either the Library or any derivative work under copyright law: that is to say, a work containing the Library or a portion of it, either verbatim or with modifications and/or translated straightforwardly into another language. (Hereinafter, translation is included without limitation in the term "modification".) "Source code" for a work means the preferred form of the work for making modifications to it. For a library, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the library. Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running a program using the Library is not restricted, and output from such a program is covered only if its contents constitute a work based on the Library (independent of the use of the Library in a tool for writing it). Whether that is true depends on what the Library does and what the program that uses the Library does. 1. You may copy and distribute verbatim copies of the Library's complete source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and distribute a copy of this License along with the Library. You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. 2. You may modify your copy or copies of the Library or any portion of it, thus forming a work based on the Library, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: a) The modified work must itself be a software library. b) You must cause the files modified to carry prominent notices stating that you changed the files and the date of any change. c) You must cause the whole of the work to be licensed at no charge to all third parties under the terms of this License. d) If a facility in the modified Library refers to a function or a table of data to be supplied by an application program that uses the facility, other than as an argument passed when the facility is invoked, then you must make a good faith effort to ensure that, in the event an application does not supply such function or table, the facility still operates, and performs whatever part of its purpose remains meaningful. (For example, a function in a library to compute square roots has a purpose that is entirely well-defined independent of the application. Therefore, Subsection 2d requires that any application-supplied function or table used by this function must be optional: if the application does not supply it, the square root function must still compute square roots.) These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Library, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Library, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it. Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Library. In addition, mere aggregation of another work not based on the Library with the Library (or with a work based on the Library) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. 3. You may opt to apply the terms of the ordinary GNU General Public License instead of this License to a given copy of the Library. To do this, you must alter all the notices that refer to this License, so that they refer to the ordinary GNU General Public License, version 2, instead of to this License. (If a newer version than version 2 of the ordinary GNU General Public License has appeared, then you can specify that version instead if you wish.) Do not make any other change in these notices. Once this change is made in a given copy, it is irreversible for that copy, so the ordinary GNU General Public License applies to all subsequent copies and derivative works made from that copy. This option is useful when you wish to copy part of the code of the Library into a program that is not a library. 4. You may copy and distribute the Library (or a portion or derivative of it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange. If distribution of object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place satisfies the requirement to distribute the source code, even though third parties are not compelled to copy the source along with the object code. 5. A program that contains no derivative of any portion of the Library, but is designed to work with the Library by being compiled or linked with it, is called a "work that uses the Library". Such a work, in isolation, is not a derivative work of the Library, and therefore falls outside the scope of this License. However, linking a "work that uses the Library" with the Library creates an executable that is a derivative of the Library (because it contains portions of the Library), rather than a "work that uses the library". The executable is therefore covered by this License. Section 6 states terms for distribution of such executables. When a "work that uses the Library" uses material from a header file that is part of the Library, the object code for the work may be a derivative work of the Library even though the source code is not. Whether this is true is especially significant if the work can be linked without the Library, or if the work is itself a library. The threshold for this to be true is not precisely defined by law. If such an object file uses only numerical parameters, data structure layouts and accessors, and small macros and small inline functions (ten lines or less in length), then the use of the object file is unrestricted, regardless of whether it is legally a derivative work. (Executables containing this object code plus portions of the Library will still fall under Section 6.) Otherwise, if the work is a derivative of the Library, you may distribute the object code for the work under the terms of Section 6. Any executables containing that work also fall under Section 6, whether or not they are linked directly with the Library itself. 6. As an exception to the Sections above, you may also combine or link a "work that uses the Library" with the Library to produce a work containing portions of the Library, and distribute that work under terms of your choice, provided that the terms permit modification of the work for the customer's own use and reverse engineering for debugging such modifications. You must give prominent notice with each copy of the work that the Library is used in it and that the Library and its use are covered by this License. You must supply a copy of this License. If the work during execution displays copyright notices, you must include the copyright notice for the Library among them, as well as a reference directing the user to the copy of this License. Also, you must do one of these things: a) Accompany the work with the complete corresponding machine-readable source code for the Library including whatever changes were used in the work (which must be distributed under Sections 1 and 2 above); and, if the work is an executable linked with the Library, with the complete machine-readable "work that uses the Library", as object code and/or source code, so that the user can modify the Library and then relink to produce a modified executable containing the modified Library. (It is understood that the user who changes the contents of definitions files in the Library will not necessarily be able to recompile the application to use the modified definitions.) b) Use a suitable shared library mechanism for linking with the Library. A suitable mechanism is one that (1) uses at run time a copy of the library already present on the user's computer system, rather than copying library functions into the executable, and (2) will operate properly with a modified version of the library, if the user installs one, as long as the modified version is interface-compatible with the version that the work was made with. c) Accompany the work with a written offer, valid for at least three years, to give the same user the materials specified in Subsection 6a, above, for a charge no more than the cost of performing this distribution. d) If distribution of the work is made by offering access to copy from a designated place, offer equivalent access to copy the above specified materials from the same place. e) Verify that the user has already received a copy of these materials or that you have already sent this user a copy. For an executable, the required form of the "work that uses the Library" must include any data and utility programs needed for reproducing the executable from it. However, as a special exception, the materials to be distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable. It may happen that this requirement contradicts the license restrictions of other proprietary libraries that do not normally accompany the operating system. Such a contradiction means you cannot use both them and the Library together in an executable that you distribute. 7. You may place library facilities that are a work based on the Library side-by-side in a single library together with other library facilities not covered by this License, and distribute such a combined library, provided that the separate distribution of the work based on the Library and of the other library facilities is otherwise permitted, and provided that you do these two things: a) Accompany the combined library with a copy of the same work based on the Library, uncombined with any other library facilities. This must be distributed under the terms of the Sections above. b) Give prominent notice with the combined library of the fact that part of it is a work based on the Library, and explaining where to find the accompanying uncombined form of the same work. 8. You may not copy, modify, sublicense, link with, or distribute the Library except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense, link with, or distribute the Library is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. 9. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Library or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Library (or any work based on the Library), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Library or works based on it. 10. Each time you redistribute the Library (or any work based on the Library), the recipient automatically receives a license from the original licensor to copy, distribute, link with or modify the Library subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties with this License. 11. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), 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 distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Library at all. For example, if a patent license would not permit royalty-free redistribution of the Library by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Library. If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply, and the section as a whole is intended to apply in other circumstances. It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice. This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License. 12. If the distribution and/or use of the Library is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Library under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License. 13. The Free Software Foundation may publish revised and/or new versions of the Lesser 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 Library specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Library does not specify a license version number, you may choose any version ever published by the Free Software Foundation. 14. If you wish to incorporate parts of the Library into other free programs whose distribution conditions are incompatible with these, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally. NO WARRANTY 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE LIBRARY "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 LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE LIBRARY 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 LIBRARY (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 LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

Created with contents that were learned at # the last time autoconf was run, and used by git-version-gen. Must not # be present in either $(srcdir) or $(builddir) for git-version-gen to # give accurate answers during normal development with a checked out tree, # but must be present in a tarball when there is no version control system. # Therefore, it cannot be used in any dependencies. GNUmakefile has # hooks to force a reconfigure at distribution time to get the value # correct, without penalizing normal development with extra reconfigures. # # .version - present in a checked-out repository and in a distribution # tarball. Usable in dependencies, particularly for files that don't # want to depend on config.h but do want to track version changes. # Delete this file prior to any autoconf run where you want to rebuild # files to pick up a version string change; and leave it stale to # minimize rebuild time after unrelated changes to configure sources. # # It is probably wise to add these two files to .gitignore, so that you # don't accidentally commit either generated file. # # Use the following line in your configure.ac, so that $(VERSION) will # automatically be up-to-date each time configure is run (and note that # since configure.ac no longer includes a version string, Makefile rules # should not depend on configure.ac for version updates). # # AC_INIT([GNU project], # m4_esyscmd([build-aux/git-version-gen .tarball-version]), # [bug-project@example]) # # Then use the following lines in your Makefile.am, so that .version # will be present for dependencies, and so that .tarball-version will # exist in distribution tarballs. # # BUILT_SOURCES = $(top_srcdir)/.version # $(top_srcdir)/.version: # echo $(VERSION) > $@-t && mv $@-t $@ # dist-hook: # echo $(VERSION) > $(distdir)/.tarball-version case $# in 1|2) ;; *) echo 1>&2 "Usage: $0 \$srcdir/.tarball-version" \ '[TAG-NORMALIZATION-SED-SCRIPT]' exit 1;; esac tarball_version_file=$1 tag_sed_script="${2:-s/x/x/}" nl=' ' # Avoid meddling by environment variable of the same name. v= v_from_git= # First see if there is a tarball-only version file. # then try "git describe", then default. if test -f $tarball_version_file then v=`cat $tarball_version_file` || v= case $v in *$nl*) v= ;; # reject multi-line output [0-9]*) ;; *) v= ;; esac test -z "$v" \ && echo "$0: WARNING: $tarball_version_file is missing or damaged" 1>&2 fi if test -n "$v" then : # use $v # Otherwise, if there is at least one git commit involving the working # directory, and "git describe" output looks sensible, use that to # derive a version string. elif test "`git log -1 --pretty=format:x . 2>&1`" = x \ && v=`git describe --abbrev=4 --match='v*' --tags HEAD 2>/dev/null \ || git describe --abbrev=4 --tags HEAD 2>/dev/null` \ && v=`printf '%s\n' "$v" | sed "$tag_sed_script"` \ && case $v in v[0-9]*) ;; *) (exit 1) ;; esac then # Is this a new git that lists number of commits since the last # tag or the previous older version that did not? # Newer: v6.10-77-g0f8faeb # Older: v6.10-g0f8faeb case $v in *-*-*) : git describe is okay three part flavor ;; *-*) : git describe is older two part flavor # Recreate the number of commits and rewrite such that the # result is the same as if we were using the newer version # of git describe. vtag=`echo "$v" | sed 's/-.*//'` commit_list=`git rev-list "$vtag"..HEAD 2>/dev/null` \ || { commit_list=failed; echo "$0: WARNING: git rev-list failed" 1>&2; } numcommits=`echo "$commit_list" | wc -l` v=`echo "$v" | sed "s/\(.*\)-\(.*\)/\1-$numcommits-\2/"`; test "$commit_list" = failed && v=UNKNOWN ;; esac # Change the first '-' to a '.', so version-comparing tools work properly. # Remove the "g" in git describe's output string, to save a byte. v=`echo "$v" | sed 's/-/./;s/\(.*\)-g/\1-/'`; v_from_git=1 else v=UNKNOWN fi v=`echo "$v" |sed 's/^v//'` # Test whether to append the "-dirty" suffix only if the version # string we're using came from git.
