Alexey Botchkov	5c01f1ac14	MDEV-15 Log all sql errors. modified for MySQL 5.5. Logger service moved to the plugin/sql_errlog directory to be properly used later. plugin/sql_errlog/sql_errlog.c: Fixes for bugs #956427 (SQL_ERROR_LOG plugin produces bogus warnings about sql-error-log-size-limit value) and #956463 (Server crashes if SQL_ERROR_LOG fails to initialize) they're also MDEV-184 and MDEV-183 The sql_error_log_deinit() should be prepared for the logger_file to be NULL. The logger_file_size_limit upper limit wasn't properly set.	14 years ago
Michael Widenius	a579adea66	Cleanups: - Don't use SAFEMALLOC on valgrind builds (slows things down) - Added back lost option from 5.3: debug-mutex-deadlock-detector - Flush pages before taking lock mutex (speeds up closing of Aria tables). BUILD/SETUP.sh: - Don't use SAFEMALLOC on valgrind builds (slows things down) sql/lock.cc: Make default argument explicit (improves readability) sql/mysqld.cc: Removed compiler warnings Sorted debug options alphabetically Added back lost option from 5.3: debug-mutex-deadlock-detector storage/maria/ma_close.c: Flush pages before taking lock mutex (speeds up closing of Aria tables). storage/maria/ma_open.c: More DBUG_PRINT storage/maria/maria_def.h: Better DBUG_PRINT storage/maria/trnman.c: Better DBUG_PRINT	14 years ago
Alexey Botchkov	07a82c58a7	MDEV-15 Log all SQL errors. Added the logger service that provides us with the rotating logs. The plugin SQL_ERROR_LOG added. It logs the errors using the 'logger service' for the rotating log files. the example record from the log: 2012-03-09 15:07:29 root[root] @ localhost [] ERROR 1146: Table 'test.xyz' doesn't exist : select * from test.xyz	14 years ago

Dmitry Shulga	97883d3c04	Fixed bug#11753187 (formerly known as bug 44585): SP_CACHE BEHAVES AS MEMORY LEAK. Background: - There are caches for stored functions and stored procedures (SP-cache); - There is no similar cache for events; - Triggers are cached together with TABLE objects; - Those SP-caches are per-session (i.e. specific to each session); - A stored routine is represented by a sp_head-instance internally; - SP-cache basically contains sp_head-objects of stored routines, which have been executed in a session; - sp_head-object is added into the SP-cache before the corresponding stored routine is executed; - SP-cache is flushed in the end of the session. The problem was that SP-cache might grow without any limit. Although this was not a pure memory leak (the SP-cache is flushed when session is closed), this is still a problem, because the user might take much memory by executing many stored routines. The patch fixes this problem in the least-intrusive way. A soft limit (similar to the size of table definition cache) is introduced. To represent such limit the new runtime configuration parameter 'stored_program_cache' is introduced. The value of this parameter is stored in the new global variable stored_program_cache_size that used to control the size of SP-cache to overflow. The parameter 'stored_program_cache' limits number of cached routines for each thread. It has the following min/default/max values given from support: min = 256, default = 256, max = 512 * 1024. Also it should be noted that this parameter limits the size of each cache (for stored procedures and for stored functions) separately. The SP-cache size is checked after top-level statement is parsed. If SP-cache size exceeds the limit specified by parameter 'stored_program_cache' then SP-cache is flushed and memory allocated for cache objects is freed. Such approach allows to flush cache safely when there are dependencies among stored routines. sql/mysqld.cc: Added global variable stored_program_cache_size to store value of configuration parameter 'stored-program-cache'. sql/mysqld.h: Added declaration of global variable stored_program_cache_size. sql/sp_cache.cc: Extended interface for sp_cache by adding helper routine sp_cache_enforce_limit to control size of stored routines cache for overflow. Also added method enforce_limit into class sp_cache that implements control of cache size for overflow. sql/sp_cache.h: Extended interface for sp_cache by adding standalone routine sp_cache_enforce_limit to control size of stored routines cache for overflow. sql/sql_parse.cc: Added flush of sp_cache after processing of next sql-statement received from a client. sql/sql_prepare.cc: Added flush of sp_cache after preparation/execution of next prepared sql-statement received from a client. sql/sys_vars.cc: Added support for configuration parameter stored-program-cache.	14 years ago

Manish Kumar	e69da6dc3e	BUG#11752315 - 43460: STOP SLAVE UNABLE TO COMPLETE WHEN SLAVE THREAD IS TRYING TO RECONNECT TO Problem : The basic problem is the way the thread sleeps in mysql-5.5 and also in mysql-5.1 when we execute a stop slave on windows platform. On windows platform if the stop slave is executed after the master dies, we have this long wait before the stop slave return a value. This is because there is a sleep of the thread. The sleep is uninterruptable in the two above version, which was fixed by Davi patch for the BUG#11765860 for mysql-trunk. Backporting his patch for mysql-5.5 fixes the problem. Solution : A new pair of mutex and condition variable is introduced to synchronize thread sleep and finalization. A new mutex is required because the slave threads are terminated while holding the slave thread locks (run_lock), which can not be relinquished during termination as this would affect the lock order. mysql-test/suite/rpl/r/rpl_start_stop_slave.result: The result file associated with the test added. mysql-test/suite/rpl/t/rpl_start_stop_slave.test: A test to check the new functionality. sql/rpl_mi.cc: The constructor using the new mutex and condition variables for the master_info. sql/rpl_mi.h: The condition variable and mutex have been added for the master_info. sql/rpl_rli.cc: The constructor using the new mutex and condition variables for the realy_log_info. sql/rpl_rli.h: The condition variable and mutex have been added for the relay_log_info. sql/slave.cc: Use a timed wait on a condition variable to implement a interruptible sleep. The wait is registered with the THD object so that the thread will be woken up if killed.	14 years ago
Vladislav Vaintroub	139bf5ce4c	MDEV-103: 'debug' is disabled in this build warnings causes tests to fail The root cause is that after recent fixes around --debug variable (lp:909051) the variable is now available in both release and debug builds, such that MTR cannot tell a debug compiled server from optimized one. To fix, assign a special default value 'disabled' for 'debug' variable in optimized build and fix MTR to check for this special value to recognize optimized build.	14 years ago
Georgi Kodinov	10543a4a2e	Bug #11754014 : 45549: udf plugin_dir path separator inconsistency and cryptic error 1126 message The problem was that dlopen() related code was using just a subset of the path normalization routines used in other places. Fixed the expansion of the pre-dlopen() behavior for plugins and UDFs to use a platform-dependent consistent encoding of the paths. Fixed the error dlopen() error handling to take the correct error message and strip off the trailing newline character(s). Fixed tests to do a platform independent replace of directories and to account for the traling slash.	14 years ago

Luis Soares	eec4836a1b	BUG#11745230: 12133: MASTER.INDEX FILE KEEPS MYSQLD FROM STARTING IF BIN LOG HAS BEEN MOVED When moving the binary/relay log files from one location to another and restarting the server with a different log-bin or relay-log paths, would cause the startup process to abort. The root cause was that the server would not be able to find the log files because it would consider old paths for entries in the index file instead of the new location. What's even worse, the relative paths would not be considered relative to the path provided in log-bin and relay-log, but to mysql_data_dir. We fix the cases where the server contains relative paths. When the server is reading from the index file, it checks whether the entry contains relative paths. If it does, we replace it with the absolute path set in log-bin/relay-log option. Absolute paths remain unchanged and the index must be manually edited to consider the new log-bin and/or relay-log path (this should be documented). This is a fix for a GA version, that does not break behavior (that much). For development versions, we should go with Zhenxing's approach that removes paths altogether from index files. mysql-test/include/begin_include_file.inc: Added parameter to keep the begin_include_file.inc silent. Useful when including scripts that contain platform dependent parameters, for example: --let $rpl_server_parameters=--log-bin=$tmpdir/slave-bin --relay-log=$tmpdir/slave-relay-bin --let $keep_include_silent=1 source include/rpl_start_server.inc; --let $keep_include_silent=0 We want the paths ($tmpdir/slave-bin and $tmpdir/slave-relay-bin) not to be in the result file. mysql-test/suite/rpl/t/rpl_binlog_index.test: Test case. sql/log.cc: When finding the corresponding log entry in the index file, we first normalize the paths before doing the comparison. This will make relative paths to be turned into absolute paths (based on the opt_bin_logname or opt_relay_logname) and then compared against also, expanded paths entered, through CHANGE MASTER for instance. sql/log.h: Added normalize_binlog_name, which turns relative paths, into absolute paths given the parameter: is_relay_log ? opt_relay_logname : opt_bin_logname . sql/mysqld.cc: Exposing opt_bin_logname. sql/mysqld.h: Exposing opt_bin_logname.	14 years ago
