mysqld maintains a list of TABLE objects for all temporary
tables created within a session in THD. Here each table is
represented by a TABLE object.
A query referencing a particular temporary table for more
than once, however, failed with ER_CANT_REOPEN_TABLE error
because a TABLE_SHARE was allocate together with the TABLE,
so temporary tables always had only one TABLE per TABLE_SHARE.
This patch lift this restriction by separating TABLE and
TABLE_SHARE objects and storing TABLE_SHAREs for temporary
tables in a list in THD, and TABLEs in a list within their
respective TABLE_SHAREs.
different fix. remove old ones, wait for THD to be fully
initialized before continuing with the server startup process.
This reverts commits db2e21b, 13615c5, 3f515a0, 70113ee.
* Wait for aborted thd (victim) to release MDL locks
* Skip aborting an already aborted thd
* Defer setting OK status in case of CTAS
* Minor cosmetic changes
* Added a test case
Annotate_rows event needs to be preserved until the last Rows event has
been applied because after it has been applied thd->query points to the
query stored inside this event.
wsrep-patch uses same connection name for constructing Master_info
objects. As a result all existing wsrep Master_info objects refer
to same rpl_filter object. This could lead to race when multiple
threads try to delete/destruct Master_info object, as they would
all try to delete the same relay_log object.
Fixed by adding a check in Master_info's destructor to not free
the "wsrep" rpl_filter, so that its reused by current & subsequent
wsrep threads and later reclaimed by free_all_rpl_filters() during
server shutdown.
Merged lp:maria/maria-10.0-galera up to revision 3879.
Added a new functions to handler API to forcefully abort_transaction,
producing fake_trx_id, get_checkpoint and set_checkpoint for XA. These
were added for future possiblity to add more storage engines that
could use galera replication.
Analysis: Problem is that we execute galera code when we are actually
executing asyncronoush replication.
Fix: Do not execute galera code if wsrep provider is not set.
This is now otherwise on level wsrep-25.9, but storage/innobase has not been fully merged
wsrep-5.5 is not good source for that, so we probably have to cherry pick innodb changes from wsrep-5.6
