Two threads both try a shutdown sequence which creates a race to the
de-init/free of certain resources.
This exists in similar form in the client as 17926: "mysql.exe crashes
when ctrl-c is pressed in windows."
duplicate fields removed, st_mysql_storage_engine added to support
run-time handlerton initialization (no compiler warnings), handler API
is now tied to MySQL version, handlerton->plugin mapping added
(slot-based), dummy default_hton removed, plugin-type-specific
initialization generalized, built-in plugins are now initialized too,
--default-storage-engine no longer needs a list of storage engines
in handle_options().
mysql-test-run.pl bugfixes
Replaced COND_refresh with COND_global_read_lock becasue of a bug in NTPL threads when using different mutexes as arguments to pthread_cond_wait()
The original code caused a hang in FLUSH TABLES WITH READ LOCK in some circumstances because pthread_cond_broadcast() was not delivered to other threads.
This fixes:
Bug#16986: Deadlock condition with MyISAM tables
Bug#20048: FLUSH TABLES WITH READ LOCK causes a deadlock
- Scheduler is either initialized at server start or never.
Starting & stopping is now suspending & resuming.
- The scheduler has clear OO interface
- Now all calls to the scheduler are synchronous
- GLOBAL event_scheduler uses thd::sys_var_tmp (see set_var.cc)
- External API is encapsulated into class Events
- Includes fixes for all comments of Kostja's review of 19.05.2005
Starting to merge into 5.1-release (5.1.10) and push
- A segfault occured when the function 'kill_server' called
'my_sigset' with signal number 0. 'my_sigset' is a macro which
uses 'sigaction' to install the signal handler with an invalid
signal number will on most platforms return EINVAL but yields
a segfauilt on IRIX 6.5
- The server crash was detected by mysqld_safe and it was restarted although
a shutdown was requested.
- Semantics of kill_server(0) is not known, leaving it intact
That option was used to suppress the XID from the output of SHOW BINLOG EVENTS (to create a repeatable testsuite),
was available only in debug builds, and was explicitely marked as "may be removed in future versions" in mysqld --help.
Idea of the removal approved by the replication team.
Bug #19606: ssl variables are not displayed in show variables
Bug #19616: log_queries_not_using_indexes is not listed in show variables
Make basedir, datadir, tmpdir, log_queries_not_using_indexes, ssl_ca,
ssl_capath, ssl_cert, ssl_cipher, and ssl_key all available both from
SHOW VARIABLES and as @@variables.
As a side-effect of this change, log_queries_not_using_indexes can
be changed at runtime (but only globally, not per-connection).
"NDB replication fails when no explicit--binlog-format given"
fix initialization, storage engine initialization must occur after
logging type is configured
Move plugin declarations after system functions have been checked
(Fixes problem with ndb_config failing becasue SHM is not declared)
Fixed some memory leaks
