- Increase number of transaction objects available in ndbd
 - Most likely this is a timing related issue.

 - Fix faulty regex used for filtering out suspicious warnings, causing
   warnings/errors from previous tests to be reported

BUG#42383 2009-01-28 lsoares 
"This fails in embedded and on windows. Note that this test is not run 
on windows and on embedded in PB for main trees currently"

 - Disable the two patterns that previously have been faulty - for now.

 - Improve error message for "found warnings in server log file"

 - First try LOAD DATA INFILE and fall back to LOAD DATA LOCAL INFILE if
   that fails.

 - Fix the regex for finding core files ie. anything that starts with "core" 
 - Add collection of *.dmp files on windows.

 - Use empty escape char as not to convert "\test" to a tab + "est"
   when loading the servers .err file

 - Remove double escape of [ and ]

 - Bypass --secure-file-priv by loading the file from the client
   using LOAD DATA LOCAL INFILE

 - Make a rough filtering of the servers error log and write
   all suspicious warnings to $error_log.warnings
   The .warnings file is then examined more carefully by check_warnings.test
 - This will speed things up, doing all of this in a server running
   under valgrind takes far too long time.

 - Add a "skip-ssl=1" to [mysqltest] section so that 
   mysqltest will not run with ssl turned on by default 
   but stil be able to turn it on when requested
 - This avoids that check_warnings and check_testcase
   connects to the server woth SSL turned on

The test fails with timeout when applying diff on two tables.

In this test case, there can be a situation when the slave is not yet synced
with the master, thence the changes may not be on the slave at diff time.

This patch addresses this issue by synchronizing master and slave before the
diff takes place.

 - pass empty "--plugin-dir" if simple parser was not found.

 - Pass verbose flag to My::SafeProcess also when starting
   check_warnings and run_on_all

 - Suppress intentional safemalloc dump warnings
 - add fflush(stdout) to make sure that the "End safemalloc memory dump." marker is flushed.

 - rewrite "check warnings" to be faster by not creating a full join
   between error_log and suspicious_patterns while running REGEXP.
   Instead add a column to error_log that will be set to 1 to indicate
   a warning and run the 6 REGEXP's we have for suspicious lines as
   6 separate full table scans.
 - Remove the "suspicious_patterns" table from mtr db
 - Use 'xykls37' as separator when loading the error log, that line should
   hopefully never exist in a line that should be a warning

 - default parallel to 1(again)

 - turn auto detection of parallelism value ON again

 - disable check of .err-old until bug has been fixed

 - fix typo, use "$old_log_error" as name when loading from .err-old file

 - extend debug prints for "permission denied"

 - Clear test variables "comment" and "logfile" to make sure thay aren't
  already set from previous run of same test
 - Print warning if test result already set and set it anyway

 - fix typo

 - Don't save ndb_*_fs directory after test failure

 - Add name of error log file to the erro log table to get better
   erorr message when warning is found

 - Add debug prints for analyzing mkdir "Permission denied" failure

 - Rewrite "check testcase" to use LOAD DATA INFILE instead of 'load_file'
   in order to speed up the reading of the servers error log.

mysql-test/include/check-warnings.test:
  Use LOAD DATA to load the servers error log into error_log table and then
  call 'check_warning' stored procedure to filter out any unexpected warnings

The original goal of the test, as reported on BUG #25721, is to check whether 
a deadlock happens or not when concurrently CREATING/ALTERING/DROPPING the 
same server. For that a procedure (p1) is created that runs the exact same 
CREATE/ALTER/DROP statements for 10K iterations and two different connections 
(threads - t1 and t2) call p1 concurrently. At the end of the 10K iterations, 
the test checks if there was errors while running the loop (SELECT e >0).
      
The problem is that In some cases it may happen that one thread, t1, gets 
scheduled to execute with just enough time to complete the iteration and 
never bumps into the other thread t2. Meaning that t1 will never run into an 
SQL exception. On the other hand, the other thread, t2, may run into t1 and 
never issue any/part of its own statements because it will throw an SQLEXCEPTION. 
This is probably the case for failures where only one value differs.
      
Furthermore, there is a third scenario: both threads are scheduled to run 
interleaved for each iteration (or even one thread completes all iterations 
before the other starts). In this case, both will succeed without any error. 
This is probably the case for the failure that reports two different values.
      
This patch addresses the failure in pushbuild by removing the error counting 
and the printout (SELECT > 0) at the end of the test. A timeout should occur 
if the error that the test is checking surfaces.

 - Additional patch with improved protection by putting it all inside an "eval"
 - Calling 'hostpath' on a truncated socket may also croak.
 - Remove the need to create any directory parts of "path" inside the function.
