Davi Arnaut	f6deb00a56	WL#5665: Removal of the autotools-based build system The autotools-based build system has been superseded and is being removed in order to ease the maintenance burden on developers tweaking and maintaining the build system. In order to support tools that need to extract the server version, a new file that (only) contains the server version, called VERSION, is introduced. The file contents are human and machine-readable. The format is: MYSQL_VERSION_MAJOR=5 MYSQL_VERSION_MINOR=5 MYSQL_VERSION_PATCH=8 MYSQL_VERSION_EXTRA=-rc The CMake based version extraction in cmake/mysql_version.cmake is changed to extract the version from this file. The configure to CMake wrapper is retained for backwards compatibility and to support the BUILD/ scripts. Also, a new a makefile target show-dist-name that prints the server version is introduced.	16 years ago

Davi Arnaut	a10ae35328	Bug#34043: Server loops excessively in _checkchunk() when safemalloc is enabled Essentially, the problem is that safemalloc is excruciatingly slow as it checks all allocated blocks for overrun at each memory management primitive, yielding a almost exponential slowdown for the memory management functions (malloc, realloc, free). The overrun check basically consists of verifying some bytes of a block for certain magic keys, which catches some simple forms of overrun. Another minor problem is violation of aliasing rules and that its own internal list of blocks is prone to corruption. Another issue with safemalloc is rather the maintenance cost as the tool has a significant impact on the server code. Given the magnitude of memory debuggers available nowadays, especially those that are provided with the platform malloc implementation, maintenance of a in-house and largely obsolete memory debugger becomes a burden that is not worth the effort due to its slowness and lack of support for detecting more common forms of heap corruption. Since there are third-party tools that can provide the same functionality at a lower or comparable performance cost, the solution is to simply remove safemalloc. Third-party tools can provide the same functionality at a lower or comparable performance cost. The removal of safemalloc also allows a simplification of the malloc wrappers, removing quite a bit of kludge: redefinition of my_malloc, my_free and the removal of the unused second argument of my_free. Since free() always check whether the supplied pointer is null, redudant checks are also removed. Also, this patch adds unit testing for my_malloc and moves my_realloc implementation into the same file as the other memory allocation primitives.	16 years ago

Davi Arnaut	5dec0c9637	Bug#53445: Build with -Wall and fix warnings that it generates Fix various mismatches between function's language linkage. Any particular function that is declared in C++ but should be callable from C must have C linkage. Note that function types with different linkages are also distinct. Thus, if a function type is declared in C code, it will have C linkage (same if declared in a extern "C" block).	16 years ago

He Zhenxing	522311e0c9	Bug#49557 "semisync" plugin test fails on Windows The problem was because the gettimeofday function was incorrect implemented for Windows, and so the semisync master did not wait for slave reply properly on Windows. Fixed by removing the gettimeofday function for Windows, and using set_timespec function to get current time for all platforms.	17 years ago
	85589577e7	BUG#50157 Assertion !active_tranxs_->is_tranx_end_pos(..) in ReplSemiSyncMaster::commitTrx The root cause of the crash is that a TranxNode is freed before it is used. A TranxNode is allocated and inserted into the active list each time a log event is written and flushed into the binlog file. The memory for TranxNode is allocated with thd_alloc and will be freed at the end of the statement. The after_commit/after_rollback callback was supposed to be called before the end of each statement and remove the node from the active list. However this assumption is not correct in all cases(e.g. call 'CREATE TEMPORARY TABLE myisam_t SELECT * FROM innodb_t' in a transaction and delete all temporary tables automatically when a session closed), and can cause the memory allocated for TranxNode be freed before it was removed from the active list. So The TranxNode pointer in the active list would become a wild pointer and cause the crash. After this patch, We have a class called a TranxNodeAllocate which manages the memory for allocating and freeing TranxNode. It uses my_malloc to allocate memory.	17 years ago

He Zhenxing	16ec25c0a8	Bug#49020 Semi-sync master crashed with free_pool == NULL, assertion `free_pool_' Before this patch, semisync assumed transactions running in parallel can not be larger than max_connections, but this is not true when the event scheduler is executing events, and cause semisync run out of preallocated transaction nodes. Fix the problem by allocating transaction nodes dynamically. This patch also fixed a possible deadlock when running UNINSTALL PLUGIN rpl_semi_sync_master and updating in parallel. Fixed by releasing the internal Delegate lock before unlock the plugins.	17 years ago

He Zhenxing	b92ec52915	Backport BUG#47298 Semisync: always wait until timeout if no semi-sync slave available Add an option to control whether the master should keep waiting until timeout when it detected that there is no semi-sync slave available. The bool option 'rpl_semi_sync_master_wait_no_slave' is 1 by defalt, and will keep waiting until timeout. When set to 0, the master will switch to asynchronous replication immediately when no semi-sync slave is available.	17 years ago
He Zhenxing	64fc766c93	BUG#45674 FLUSH STATUS does not reset semisynchronous counters Semi-sync status were not reset by FLUSH STATUS, this was because all semi-sync status variables are defined as SHOW_FUNC and FLUSH STATUS could only reset SHOW_LONG type variables. This problem is fixed by change all status variables that should be reset by FLUSH STATUS from SHOW_FUNC to SHOW_LONG. After the fix, the following status variables will be reset by FLUSH STATUS: Rpl_semi_sync_master_yes_tx Rpl_semi_sync_master_no_tx Note: normally, FLUSH STATUS itself will be written into binlog and be replicated, so after FLUSH STATS, one of Rpl_semi_sync_master_yes_tx Rpl_semi_sync_master_no_tx can be 1 dependent on the semi-sync status. So it's recommended to use FLUSH NO_WRITE_TO_BINLOG STATUS to avoid this.	17 years ago
He Zhenxing	7d3d0fc303	Backport Bug#45852 Semisynch: Last_IO_Error: Fatal error: Failed to run 'after_queue_event' hook Errors when send reply to master should never cause the IO thread to stop, because master can fall back to async replication if it does not get reply from slave. The problem is fixed by deliberately ignoring the return value of slaveReply.	17 years ago
He Zhenxing	55842061e7	Backport BUG#45848 Semisynchronous replication internals are visible in SHOW PROCESSLIST and logs Semi-sync uses an extra connection from slave to master to send replies, this is a normal client connection, and used a normal SET query to set the reply information on master, which is visible to user and may cause some confusion and complaining. This problem is fixed by using the method of sending reply by using the same connection that is used by master dump thread to send binlog to slave. Since now the semi-sync plugins are integrated with the server code, it is not a problem to use the internal net interfaces to do this. The master dump thread will mark the event requires a reply and wait for the reply when the event just sent is the last event of a transaction and semi-sync status is ON; And the slave will send a reply to master when it received such an event that requires a reply.	17 years ago
He Zhenxing	d8b4e637a0	Fix semisync master/slave status always showed as OFF on sparc On sparc, semisync master/slave status is always showed as OFF, this is fixed by change rpl_semisync_master/slave_status variables from long to char.	17 years ago
