The official Debian Wheezy MySQL packages have versions like 5.5.30+dfsg-xxx.
Such version is larger than 5.5.30-yyy, so apt prefers it.
So use instead 5.5.30+maria-yyy, which is larger and can be pulled in
automatically by apt.
Also included are a couple of fixes for test failures in buildbot.
Merge of 10.0-mdev26 feature tree into 10.0-base.
Global transaction ID is prepended to each event group in the binlog.
Slave connect can request to start from GTID position instead of specifying
file name/offset of master binlog. This facilitates easy switch to a new
master.
Slave GTID state is stored in a table mysql.rpl_slave_state, which can be
InnoDB to get crash-safe slave state.
GTID includes a replication domain ID, allowing to keep track of distinct
positions for each of multiple masters.
* print "table doesn't exist in engine" when a table doesn't exist in the engine,
instead of "file not found" (if no file was involved)
* print a complete filename that cannot be found ('t1.MYI', not 't1')
* it's not an error for a DROP if a table doesn't exist in the engine (or some table
files cannot be found) - if the DROP succeeded regardless
Adjust full test suite to work with GTID.
Huge patch, mainly due to having to update .result file for all SHOW BINLOG
EVENTS and mysqlbinlog outputs, where the new GTID events pop up.
Everything was painstakingly checked to be still correct and valid .result
file updates.

Bug#16035412 MYSQL SERVER 5.5.29 WRONG SORTING USING COMPLEX INDEX
This is a fix for a regression introduced by Bug#12667154:
Bug#12667154 attempted to fix a performance problem with subqueries
that did filesort. For doing filesort, the optimizer creates a quick
select object to use when building the sort index. This quick select
object was deleted after the first call to create_sort_index(). Thus,
for queries where the subquery was executed multiple times, the quick
object was only used for the first execution. For all later executions
of the subquery, filesort used a complete table scan for building the
sort index. The fix for Bug#12667154 tried to fix this by not deleting
the quick object after the first execution of create_sort_index() so
that it would be re-used for building the sort index by the following
executions of the subquery.
This regression introduced in Bug#12667154 is that due to not deleting
the quick select object after building the sort index, the quick
object could in some cases be used also during the second phase of the
execution of the subquery instead of using the created sort
index. This caused wrong results to be returned.
The fix for this issue is to delete the reference to the select object
after it has been used in create_sort_index(). In this way the select
and quick objects will not be available when doing the second phase
of the execution of the select operation. To ensure that the select
object can be re-used for the following executions of the subquery
we make a copy of the select pointer. This is used for restoring the
select object after the select operation is completed.
mysql-test/suite/innodb/r/innodb_mysql.result:
Changed explain output: The explain now contains "Using where" since we
have restored the select pointer after doing the filesort operation.
sql/sql_select.cc:
Change create_sort_index() so that it always sets the pointer to
the select object to NULL. This is done in order to avoid that the
select->quick object can be used when execution the main part of
the select operation.
sql/sql_select.h:
New member in JOIN_TAB: saved_select. Used by create_sort_index to
make a backup copy of the select pointer.
- Added --verbose to BUILD scripts to get make to write out compile commands.
- Detect if AM_EXTRA_MAKEFLAGS=VERBOSE=1 was used with build scripts.
- Don't write warnings about replication variables when doing bootstrap.
- Fixed that mysql_cond_wait() and mysql_cond_timedwait() will report original source file in case of errors.
- Ignore some compiler warnings
BUILD/FINISH.sh:
Detect if AM_EXTRA_MAKEFLAGS=VERBOSE=1 or --verbose was used
BUILD/SETUP.sh:
Added --verbose to print out the full compile lines
Updated help message
client/mysqltest.cc:
Fixed that one can use 'replace' with cat_file
cmake/configure.pl:
If --verbose is used, get make to write out compile commands
debian/dist/Debian/rules:
Added $AM_EXTRA_MAKEFLAGS to get VERBOSE=1 on buildbot builds
debian/dist/Ubuntu/rules:
Added $AM_EXTRA_MAKEFLAGS to get VERBOSE=1 on buildbot builds
include/my_pthread.h:
Made set_timespec_time_nsec() more portable.
include/mysql/psi/mysql_thread.h:
Fixed that mysql_cond_wait() and mysql_cond_timedwait() will report original source file in case of errors.
mysql-test/suite/innodb/r/auto_increment_dup.result:
Fixed wrong DBUG_SYNC
mysql-test/suite/innodb/t/auto_increment_dup.test:
Fixed wrong DBUG_SYNC
mysql-test/suite/perfschema/include/upgrade_check.inc:
Make test more portable for changes in *.sql files
mysql-test/suite/perfschema/r/pfs_upgrade.result:
Updated test results
mysql-test/valgrind.supp:
Ignore running Aria checkpoint thread
scripts/mysqlaccess.sh:
Changed reference of bugs database
Ensure that also client-server group is read.
sql/handler.cc:
Added missing syncpoint
sql/mysqld.cc:
Don't write warnings about replication variables when doing bootstrap
sql/mysqld.h:
Don't write warnings about replication variables when doing bootstrap
sql/rpl_rli.cc:
Don't write warnings about replication variables when doing bootstrap
sql/sql_insert.cc:
Don't mask SERVER_SHUTDOWN in insert_delayed
This is done to be able to distingush between shutdown and interrupt errors
support-files/compiler_warnings.supp:
Ignore some compiler warnings in xtradb,innobase, oqgraph, yassl, string3.h
With MDEV-532, the binlog_checkpoint event is logged asynchronously
from a binlog background thread. This causes some sporadic failures
in some test cases whose output depends on order of events in
binlog.
Fix using an include file that waits until the binlog checkpoint
event has been logged before proceeding with the test case.
btr_lift_page_up() writes wrong page number (different by -1) for upper than father page.
But in almost all of the cases, the father page should be root page, no upper
pages. It is very rare path.
In addition the leaf page should not be lifted unless the father page is root.
Because the branch pages should not become the leaf pages.

mysql-test/t/innodb_mysql_lock.test:
change the variable from the test, not from the .opt file.
one mysqld restart less.

fix dos line endings
sql/handler.cc:
don't access the uninitialized variable
SECONDARY INDEX UPDATES MAKE CONSISTENT READS DO O(N^2) UNDO PAGE
LOOKUPS (honoring kill query while accessing sec_index)
If secondary index is being used for select query evaluation and this
query is operating with consistent read snapshot it might take good time for
secondary index to return back control to mysql as MVCC would kick in.
If user issues "kill query <id>" while query is actively accessing
secondary index it will not be honored as there is no hook to check
for this condition. Added hook for this check.

Parallely secondary index taking too long to evaluate for consistent
read snapshot case is being examined for performance improvement. WL#6540.
