Jan Lindström	5d1ec1b951	MDEV-5247: DB locked up at btr0cur.c line 568. There is inconsistent and non logical usage of have_LRU_mutex and incorrect value on ha_innodb.cc when buf_LRU_free_block is called. Additionally, for future long semaphore wait cases added a new configuration variable innodb_use_stacktrace. If this variable is true a signal handler for SIGUSR2 is installed when InnoDB server starts and when a long semaphore wait is detected at sync/sync0array.c we send SIGUSR2 signal to waiting thread and thread that has acuired RW-latch. For both threads a full stacktrace is produced as well as its is possible.	12 years ago

unknown	d93b4c5394	MWL#163 lp:798213: Remove the --innodb-release-locks-early feature. The bug lp:798213 exposes a design flaw in --innodb-release-locks-early. It does not work with InnoDB crash recovery, so it breaks transactional integrety. So remove the feature.	15 years ago

unknown	7a28f61ded	MBug#643463: Slow XtraDB shutdown: Fix more sleeps delaying shutdown. This patch removes most remaining delays due to uninteruptible sleep() during shutdown, as found using PMP. This makes standard test run very close in speed to with --loose-innodb-fast-shutdown=2, and greatly speeds up running the test suite. sql/mysqld.cc: Poll for threads to die every 20 msec during shutdown, rather than force a wait for 2 full seconds should one thread be a little slow to exit (this was seen occasionally in mysql-test-run). storage/xtradb/include/srv0srv.h: Rename the event, as we now use it to wakeup more threads during shutdown. storage/xtradb/log/log0log.c: Rename the event, as we now use it to wakeup more threads during shutdown. storage/xtradb/srv/srv0srv.c: Replace some hardcoded sleep()s with os_wait_event_time() that can be interrupted early during server shutdown to avoid unnecessary delays.	15 years ago
unknown	e55c4836a1	MBug#643463: slow XtraDB shutdown due to 10 second sleep in purge thread Implement os_event_wait_time() for POSIX systems. In the purge thread, use os_event_wait_time() when sleeping rather than sleep, and signal the event when server shuts down, so we do not need to wait for upto 10 seconds until the purge thread wakes up. Also fix bug that warnings that were pushed after we call set_ok_status() were not included in the waning count sent to the client in the result packet. Also in mysqltest, in recursive die() invocation at least print the message before aborting. client/mysqltest.cc: If we detect recursive die(), at least print the message before aborting. mysql-test/r/warnings_debug.result: Test case. mysql-test/t/warnings_debug.test: Test case. sql/handler.cc: Force generation of a warning with specific debug option, for testing. sql/protocol.cc: Fix wrong DBUG_ENTER sql/sql_class.h: Add method to count warnings pushed after set_ok_status() is called. sql/sql_error.cc: Also count warnings pushed after set_ok_status() is called. storage/xtradb/include/os0sync.h: Implement working os_sync_wait_time() for POSIX. storage/xtradb/include/srv0srv.h: Make the purge thread wait for an event when sleeping, so we can signal it to wakeup immediately at shutdown. storage/xtradb/log/log0log.c: Make the purge thread wait for an event when sleeping, so we can signal it to wakeup immediately at shutdown. storage/xtradb/os/os0sync.c: Implement working os_sync_wait_time() for POSIX. storage/xtradb/srv/srv0srv.c: Make the purge thread wait for an event when sleeping, so we can signal it to wakeup immediately at shutdown.	15 years ago
unknown	d4fa9ef0c7	MWL#163: release of row locks in InnoDB during prepare Port the Facebook patch for releasing InnoDB row locks early to the MWL#116 framework. A new --innodb-release-locks-early option (off by default) enables a prepare_ordered() handlerton method which will release row locks and commit a transaction to memory immediately after successful prepare. If the server subsequently tries to rollback (ie. due to binlog error), crashes the server to prevent corrupting the InnoDB state. mysql-test/r/innodb_release_row_locks_early.result: Test case. mysql-test/t/innodb_release_row_locks_early-master.opt: Test case. mysql-test/t/innodb_release_row_locks_early.test: Test case. sql/log.cc: Add DEBUG_SYNC points for testing. storage/xtradb/handler/ha_innodb.cc: Release locks during prepare phase if --innodb-release-locks-early. Crash the server if we are asked to rollback after releasing locks and committing the transaction to memory. storage/xtradb/include/srv0srv.h: Add variable for --innodb-release-locks-early option. storage/xtradb/include/trx0sys.ic: If --innodb-release-locks-early, treat a transaction as committed to memory as soon as it enters the TRX_PREPARED state. storage/xtradb/srv/srv0srv.c: Add variable for --innodb-release-locks-early option.	15 years ago
