On [Open]Solaris/x86 the FPU was not switched to 64-bit double
precision mode when the server binary was built with Sun
Studio. That caused GIS test failures due to differences in
expected and actual results.
This patch aims at moving some rpl tests to be run on a daily
basis instead of running on a per push basis. To accomplish such
goal the following modifications are proposed:
- MTR: added --skip-test-list cli parameter
This option allows the user to specify more than one
disabled.def file, for example:
perl mtr --skip-test-list=list1.list --skip-test-list=list2.list
- Added collections/disabled-per-push.list
This file lists the test cases that should be disabled per
push.
- Changed mysql-test/collections/default.push
Added --skip-test-list=collections/disabled-per-push.list
to rpl_binlog_row, ps_row and n_mix runs.
- Changed mysql-test/collections/default.daily
Added rpl_binlog_row run (since it is partially run per push we
should run it fully on a daily basis).
There were two problems here:
1. misleading error message
2. abusing KILL QUERY in the test case
1. The server reported "'DELETE FROM t1' failed: 1689: Wait on a lock was
aborted due to a pending exclusive lock", while the proper error message
should be "'DELETE FROM t1' failed: 1317: Query execution was interrupted".
The problem is that the server has two different flags for
signalling that a query is being killed: THD::killed and
mysys_var::abort. The test case triggers a race: sometimes
mysys_var::abort is set earlier than THD::killed. That leads
to the following situation:
- thr_lock() checks mysys_var::abort and returns error status,
since mysys_var::abort is set;
- the caller (mysql_lock_tables()) gets an error from thr_lock(),
but THD::killed is not set, so it decides that thr_lock() couldn't
get a lock due to a pending exclusive lock.
This is a known issue with the server and it's not going to be fixed soon.
5.5 differs from 5.1 here as follows: when thr_lock() returns an error:
- 5.1 continues trying thr_lock() until success;
- 5.5 propagates the error
2. The test case uses KILL QUERY is a highly concurent environment.
The fix is to wait for the dying statement to rest in peace before
executing another DELETE FROM t1.

The 'rpl_get_master_version_and_clock' test verifies if the slave I/O
thread tries to reconnect to master when it tries to get the values of
the UNIX_TIMESTAMP, SERVER_ID from master under network disconnection.
So the master server is restarted for making the transient network
disconnection, during the period the COM_REGISTER_SLAVE failures are
produced in server log file when the slave I/O thread tries to
register on master.
To fix the problem, suppress COM_REGISTER_SLAVE failures in server log
file by mtr suppression, because they are expected.
