A crash may happenin the cases when the range optimizer tried to OR
two index merge such that the second one contained less range trees
than the first one.
The bug was introduced by the patch of MWL#24:
"index_merge: fair choice between index_merge union and range access".
independent execution plans.
Fixed a bug in Unique::unique_add that caused a crash for a query from
index_intersect_innodb on some platforms.
Fixed two bugs in opt_range.cc that led to the choice of not the
cheapest plans for index intersections.
Fixed timing test failures.
Fixed a failure in the Aria engines page cache and log handler (found with maria.maria-big test)
- This could cause a core dump when deleting big blobs.
- Added test to end_pagecache() to verify that page cache was correctly used.
- inc_counter_for_resize_op and dec_counter_for_resize_op are called same number of times.
- All page cache blocks was properly deallocated (empty)
mysql-test/suite/innodb/t/innodb_bug38231.test:
Fixed timing issue (code comment says it all)
mysql-test/suite/innodb_plugin/t/innodb_bug38231.test:
Fixed timing issue (code comment says it all)
sql/debug_sync.cc:
Fixed compiler warning
storage/maria/ma_loghandler.c:
Fixed bug found by maria.maria-big test:
- Fixed race condition between update thread logging a very big blog and checkpoint thread.
storage/maria/ma_pagecache.c:
Added assert to ensure mutex was properly locked.
Added test to end_pagecache() to verify that page cache was correctly used.
- inc_counter_for_resize_op and dec_counter_for_resize_op are called same number of times.
- All page cache blocks was properly deallocated (empty)
In pagecache_delete_internal(), properly reset counters and pins if functions aborts.
Added missing inc_counter_for_resize_op() to pagecache_wait_lock().
Added missing dec_counter_for_resize_op() to pagecache_delete()
- Make sure creation of t1 is replicated before trying to create trigger on it on slave
- Use safe #ifdef for declaration as for definition to avoid warning about unused static function.
MTR_VS_CONFIG is now determined by looking at parent directory
of sql\*\mysqld.exe, instead of looking at *\*\BuildLog.htm
Reason : VS2010 does not create BuildLog.htm, hence prior method did not work.
- Remove all mentioning of /MAP /MAPINFO link options (does not work in VS2010).
Remove map files from packaging.
- Fix warning about ETIMEDOUT being redefined.
- Fix warning about FSP_EXTENT_SIZE in xtradb (32/64 bit right shift mismatch)
- Silence warnings coming from generated code (flex/bison) in xtradb/innodb_plugin.
- Be nice to people without cygwin (me) and add win/configure-mariadb.bat with options suitable for quick compilation, e.g no embedded

Sometimes you get a timeout here; Disable the not fatal error message.
storage/xtradb/sync/sync0rw.c:
Disable compiler warning
An INSERT query log event is preceeded by an INSERT_ID intvar event if the
INSERT allocates a new auto_increment value. But if we ignore the INSERT
due to --replicate-ignore-table or similar, then the INSERT_ID event is
still executed, and the set value of INSERT_ID lingers around in the
slave sql thread THD object indefinitely until the next INSERT that
happens to need allocation of a new auto_increment value.
Normally this does not cause problems as such following INSERT would
normally come with its own INSERT_ID event. In this bug, the user had
a trigger on the slave which was missing on the master, and this
trigger had an INSERT which could be affected. In any case, it seems
better to not leave a stray INSERT_ID hanging around in the sql thread
THD indefinitely.
Note that events can also be skipped from apply_event_and_update_pos();
however it is not possible in that code to skip the INSERT without also
skipping the INSERT_ID event.
Changed rows_read and rows_sent status variables to be longlong (to avoid compiler warnings)
sql/item_func.cc:
Fixed wrong usage of alias
sql/item_subselect.cc:
Changed buffer size to ulonglong to be able detect buffers bigger than size_t
sql/item_subselect.h:
Changed buffer size to ulonglong to be able detect buffers bigger than size_t
sql/multi_range_read.cc:
Fixed compiler warning by using correct type for function argument
sql/mysqld.cc:
Changed rows_read and rows_sent status variables to be longlong
sql/opt_subselect.h:
Fixed compiler warning by using correct type for function argument
sql/sql_class.cc:
Changed rows_read and rows_sent status variables to be longlong
sql/sql_class.h:
Changed rows_read and rows_sent status variables to be longlong
Changed max_nulls_in_row to uint as this is number of columns in row.
This fixed some compiler warnings.
sql/sql_select.cc:
Added casts to avoid compiler warnings
storage/heap/ha_heap.cc:
Initilize different types separate
storage/oqgraph/ha_oqgraph.cc:
Fixed argument to store(longlong) to avoid compiler warnings
configure.in:
Added comment
mysql-test/suite/innodb_plugin/t/innodb_bug56680.test:
Disable test when run with valgrind as we get errors from buf_buddy_relocate() on work for this test.
(Should probably be investigated as this may be an issue in xtradb, but probably harmless)
Work is an amd-64 running openSUSE 1.11 and valgrind 3.4.1
mysys/charset.c:
Remove static function if not used (to remove compiler warning)
storage/xtradb/srv/srv0srv.c:
Added casts to get rid of compiler warnings
- Removed SCCS rule from Makefile.am
- Made dummy rule in sql_yacc.yy to get rid of compiler warning about not used label.
Don't use maintainer mode with valgrind (as we don't want to initialize all variables)
config/ac-macros/maintainer.m4:
Don't use maintainer mode with valgrind (as we don't want to initialize all variables)
Force initialization of variables when using -Werror (To get rid of compiler warnings)
configure.in:
Don't use maintainer mode with valgrind (as we don't want to initialize all variables)
sql/sql_yacc.yy:
Made dummy rule in sql_yacc.yy to get rid of compiler warning about not used label.
