mtr internally does the following:
1. $default_vardir=....
2. $opt_vardir=$default_vardir unless $opt_vardir;
3. $opt_vardir=realpath $opt_vardir unless IS_WINDOWS
4. if ($opt_vardir eq $default_vardir) { .... use /dev/shm ... }
thus we have to realpath $default_datadir too, otherwise
the comparison logic might be broken
Using a boolean flag for 'there is a RESET MASTER in progress' doesn't
work very well for multiple concurrent RESET MASTER statements.
Changed to a counter.
Fix MDL to report an error when a wait was killed, but preserve
the old documented behavior of GET_LOCK() where killing it is not an error.
Also remove race conditions in main.create_or_replace test
This patch ports the work that facebook has performed
to make innochecksum handle compressed tables.
the basic idea is to use actual innodb-code to perform
checksum verification rather than duplicating in innochecksum.cc.
to make this work, innodb code has been annotated with
lots of #ifndef UNIV_INNOCHECKSUM so that it can be
compiled outside of storage/innobase.
A new testcase is also added that verifies that innochecksum
works on compressed/non-compressed tables.
Merged from commit fabc79d2ea976c4ff5b79bfe913e6bc03ef69d42
from https://code.google.com/p/google-mysql/
The actual steps to produce this patch are:
take innochecksum from 5.6.14
apply changes in innodb from facebook patches needed to make innochecksum compile
apply changes in innochecksum from facebook patches
add handcrafted testcase

mysql-test/suite/maria/insert_select.result:
Added test case
mysql-test/suite/maria/insert_select.test:
Added test case
mysys/thr_lock.c:
Ensure we don't allow concurrent_insert when a read_no_write lock is in use
Stage "Filling schema table" is now properly shown in 'show processlist'
mysys/mf_keycache.c:
Simple cleanup with more comments
sql/lock.cc:
Return to original stage after mysql_lock_tables
Made 'Table lock' as a true stage
sql/sql_show.cc:
Restore original stage after get_schema_tables_result
- The code that tested if
WHERE expr=value AND expr=const
can be rewritten to:
WHERE const=value AND expr=const
was incomplete in case of STRING_RESULT.
- Moving the test into a new function, to reduce duplicate code.
FULLTEXT indexes do not permit index first lookups. By calling:
ha_index_first() with a garbage parameter, random data gets overwritten
that causes the table->field array to be corrupted. Subsequently, when
the field array is accessed, a segfault occurs.
By not allowing index statistics for FULLTEXT indexes, the problem is
resolved.
Fixing a wrong assymetric code in Arg_comparator::set_cmp_func().
It existed for a long time, but showed up in 10.0.14 after the fix
for "MDEV-6666 Malformed result for CONCAT(utf8_column, binary_string)".
MDEV-7254 Assigned expression is evaluated twice when updating column TIMESTAMP NOT NULL
The test type_timestamp failed depending on the build machine time zone.
Setting a fixed time zone for the test.
Sep_char default is now ',' like when discovery is not used
If data_charset is UTF8, column names retrieved from the header
are no longer converted to UTF8 considering they already are (MDEV-7421)

column TIMESTAMP NOT NULL
Analysis: Problem was that value->is_null() function is called
even when user had explicitly set the value for timestamp
field. Calling this function had the side effect that
expression was evaluated twice.
Fix: (by Sergei Golubchik) check instead value->null_value.
Structure of the table created by the test to archive mysql.slow_log
data didn't match the structure of mysql.slow_log. The failure only
appeared if the slow_log was not empty, which was very rare.
Updated the structure of the table.
The problem was a too low timeout for slave reconnect. It was set to 9 seconds
(10 retries with 1 second in-between). This is occasinally too short on some
Buildbot hosts, when the test crashes and restarts the master while the slave
IO thread is running.
Fix by increasing --master-retry-count for this test.
The test case injects a DBUG that will crash the server during replication,
then does a START SLAVE. We need to use --error 0,2006,2013 on the START
SLAVE, so that we will not fail the test if the server has time to crash
before the START SLAVE returns to the client.
Fixes a failure seen in Buildbot.
