A patch for alter_table-big.test has been committed earlier.
This is a patch for create-big.test:
The test used to time-out after 900 seconds.
It relied on debug sleeps that are no longer present in the
code. Since the sleeps are long gone, fixing the problem didn't
involve just updating the result file or using macro
"show_binlog_events2.inc" instead of "show binlog events"
statement. The test needed to be rewritten using debug sync
points, and result then needed to be updated.
So, the sleeps have been replaced by debug_sync points and the test execution time has
been reduced significantly.
alter_treable-big.test was failing due to the use of RAND() function which is no more
replication safe.
This has been modified using static values.
Also, 'sleep' has been replaced using 'debug_sync' and the execution time of the
test has been reduced significantly.
This test is now taken out of the disabled.def file and is being enabled.
This test case was failing on 5.5 and trunk for two reasons.
1) It waited for the "Waiting for table level lock" process
state while this state was renamed "Waiting for table
metadata lock" with the introduction of MDL in 5.5.
2) SET GLOBAL query_cache_size= 100000; gave a warning since
query_cache_size is supposed to be multiples of 1024.
This patch fixes these two issues and re-enables the test case.
Third updated patch - this version also includes copyright notice in added Perl script.
This patch implements a check for such modules at runtime. If modules are not found or unable to load, the test is skipped with
the following message:
[ skipped ] Test needs Perl modules DBI and DBD::mysql
Checks are done via a helper Perl script which looks for the module in a runtime environment that is as similar to that of the
mysqlhotcopy script as possible (thus not intended for Windows environments at this time).
The helper script tells mysql-test about the result by writing information to a temporary file that is later read by mysql-test.
See comments in added files (have_dbi_dbd-mysql.inc and checkDBI_DBD-mysql.pl) for details.
The patch also removes the mysqlhotcopy tests from the list of disabled tests.
The test result differs on windows, since
it writes out 'localhost:<port>' instead of
only 'localhost', since it uses tcp/ip instead
of unix sockets on windows.
Fixed by replacing that column.
Also requires --big-test from some long running tests
and added a weekly run of all test requiring --big-test.
- A prerequisite cleanup patch for making KILL reliable.
The test case main.kill did not work reliably.
The following problems have been identified:
1. A kill signal could go lost if it came in, short before a
thread went reading on the client connection.
2. A kill signal could go lost if it came in, short before a
thread went waiting on a condition variable.
These problems have been solved as follows. Please see also
added code comments for more details.
1. There is no safe way to detect, when a thread enters the
blocking state of a read(2) or recv(2) system call, where it
can be interrupted by a signal. Hence it is not possible to
wait for the right moment to send a kill signal. It has been
decided, not to fix it in the code. Instead, the test case
repeats the KILL statement until the connection terminates.
2. Before waiting on a condition variable, we register it
together with a synchronizating mutex in THD::mysys_var. After
this, we need to test THD::killed again. At some places we did
only test it in a loop condition before the registration. When
THD::killed had been set between this test and the registration,
we entered waiting without noticing the killed flag. Additional
checks ahve been introduced where required.
In addition to the above, a re-write of the main.kill test
case has been done. All sleeps have been replaced by Debug
Sync Facility synchronization. A couple of sync points have
been added to the server code.
To avoid further problems, if the test case fails in spite of
the fixes, the test case has been added to the "experimental"
list for now.

On Solaris with version 3.4.6, the ha_example.so shared library is built
with DTrace and the server is built without DTrace support. This occurs
because dtrace.cmake disables DTrace support for 3.4.6, but still set
HAVE_DTRACE, which causes probes_mysql.h to include probes_mysql_dtrace.h
instead of probes_mysql_nodtrace.h.
This patch fixes this by not setting HAVE_DTRACE on Solaris for GCC 3.4.6.
files for cmake had some minor bugs causing this.

Remove acquisition of LOCK_open around file system operations,
since such operations are now protected by metadata locks.
Rework table discovery algorithm to not require LOCK_open.
No new tests added since all MDL locking operations are covered
in lock.test and mdl_sync.test, and as long as these tests
pass despite the increased concurrency, consistency must be
unaffected.
Fix Bug#50555 "handler commands crash server in my_hash_first()"
as a post-merge fix (the new handler tests are not passing
otherwise).
- in hash.c, don't call calc_hash if ! my_hash_inited().
- add tests and results for the test case for Bug#50555
