5.0.77 Build 13
includes patches:
| File | Name | Version | Author | License | Comment |
|---|---|---|---|---|---|
| innodb_check_fragmentation.patch | innodb_check_fragmentation | 1.0 | Percona | GPL | This patch adds several session-scoped status variables to the MySQL server. You can use the variables to compute the fragmentation of the InnoDB data scanned in the last query executed by your connection. You can compute the fragmentation for both table scans and index scans. |
| innodb_dict_size_limit.patch | innodb_dict_size_limit | 1.0 | Google, Percona | GPL | This patch limits the size of InnoDB's data dictionary. It fixes the following problem in standard InnoDB: the data dictionary is unlimited in size, and can grow extremely large. The size depends on the number of InnoDB tables in the server. Once opened, a table is never removed from the data dictionary in standard InnoDB, so the visible symptom is steadily increasing memory usage. See the examples to see how to compute the memory usage that may be caused by this problem. |
| innodb_fsync_source.patch | Information of fsync callers in InnoDB | 1.0 | GPL | ||
| innodb_io_patches.patch | Cluster of past InnoDB IO patches | 1.1 | Percona | GPL | This patch contains fixed (control_flush_and_merge_and_read, control_io-threads, adaptive_flush) |
| innodb_io_pattern.patch | Information schema table of InnoDB IO counts for each datafile pages | 1.0 | Percona info@percona.com | GPL | INFORMATION_SCHEMA.INNODB_IO_PATTERN |
| innodb_locks_held.patch | Add locks held, remove locked records in SHOW INNODB STATUS | 1.0 | Baron Schwartz baron@xaprb.com | GPL | Bug #29126 fix |
| innodb_rw_lock.patch | Fix of InnoDB rw_locks | 1.0 | Yasufumi Kinoshita | BSD | |
| innodb_show_bp.patch | show innodb buffer pool content | 1.0 | Percona info@percona.com | GPL | |
| innodb_show_hashed_memory.patch | Adds additional information of InnoDB internal hash table memories in SHOW INNODB STATUS | 1.0 | Percona info@percona.com | GPL | |
| microsec_process.patch | Adds INFOMATION_SCHEMA.PROCESSLIST with TIME_MS column | 1.0 | Percona info@percona.com | GPL | |
| microslow_innodb.patch | Extended statistics in slow.log | 1.2 | Percona info@percona.com | GPL | |
| mirror_binlog.patch | This is port of Google's patches MirroredBinlogs and FastMasterPromotion | 1.0 | Percona | GLP | There is modified the slave IO thread to maintain a copy of the master's binlog as it writes the relay log. The copy means the file has the same name and same contents. When this is done, slave can transparently failover between master and slaves with mirror the binlog. When this is first enabled, the slave must download all of the current binlog. This can take some time. New events are not appended to the relay log until this has finished. |
| mysqld_safe_syslog.patch | Patch allows redirect output of error.log to syslog-ng | 1.0 | Percona info@percona.com | GPL | Ported from Debian |
| show_patches.patch | SHOW PATCHES | 1.0 | Jeremy Cole | N/A | |
| split_buf_pool_mutex_fixed_optimistic_safe.patch | innodb_split_buffer_pool_mutex | 1.0 | Yasufumi Kinoshita | BSD | This patch splits the single global InnoDB buffer pool mutex into several mutexes for different purposes. This reduces mutex contention. It may help if you suffer performance loss when the working set does not fit in memory. You can detect buffer pool mutex contention by examining the output of SHOW INNODB STATUS and looking at the first section, SEMAPHORES. |
| userstatsv2.patch | SHOW USER/TABLE/INDEX statistics | V2 | GPL | Added INFORMATION_SCHEMA.*_STATISTICS |
