Would not prevent mysqld from core dumping
Passes --nocore arg to safe_process, which then sets rlimit core to 0 for child

Retried tests are reported the same as ordinary ones
Prepend "retry-" to fail or pass for retried tests

(query is not 0-terminated in the log record): limit it to the true query's size.

storage/maria/ma_loghandler.c:
  Normally, when we log LOGREC_LONG_TRANSACTION_ID, undo_lsn should be 0: assert this.
storage/maria/ma_test_force_start.pl:
  this script does not work with mtr2, make it use mtr1
storage/maria/trnman.c:
  The bug's cause was that: transaction would log LOGREC_LONG_TRANSACTION_ID, then Checkpoint would run
  and skip it (because its undo_lsn is still 0), then transaction would log REDO+UNDO, then crash. At Recovery,
  REDO phase would start from Checkpoint's record LSN, so wouldn't see LOGREC_LONG_TRANSACTION_ID, and
  as Checkpoint record does not mention transaction, transaction would be unknown, so its REDO+UNDO would
  be thrown away (assumed to belong to a transaction committed long ago as unknown), so transaction
  would not be rolled back, which is wrong. Fix is: it was wrong to skip a transaction if undo_lsn is 0;
  as soon as LOGREC_LONG_TRANSACTION_ID has been logged, it becomes potentially invisible to the REDO
  phase, and so we must include this transaction in the checkpoint record.

Add sanity check that $opt_parallel > 0

MTR gives up if wanted port not available
Try next range if set to 'auto'
Also, use next number for additional threads if explicitly set

Error log gets truncated when mysqld is restarted by MTR

mysql-test/include/check-warnings.test:
  Since server doesn't have log-error, get it from env. var. set by MTR
mysql-test/lib/My/ConfigFactory.pm:
  "Hide" log-error in a comment
mysql-test/mysql-test-run.pl:
  "Hide" log-error in my.cnf by comment
  add --console to arguments on Windows
  Move .err file to var/log

Problems with use of share/mysql dir
Explicitly look for "english" language file

Faulty logic in cleanup
Put test file into tmpdir, cleanup by removing tmpdir

Don't use both "License" and "license" as RPM macro, they are the same

Bug#42888 for MySQL 5.1. Add collections of test runs to make it both configurable and transparent what kinds of tests we run during integration testing. Implement filter list in mysql-test-run.pl to filter out failures of experimental test cases, using a new status code "exp-fail", so we can tell regressions ("fail") from failures of test cases that are still in development ("exp-fail").

transparent what kinds of tests we run during integration testing.

and the directory "mysql-test/suite/jp/include"

- adding back Serg's "mtr --list-options"
- safe_mutex deadlock detector started raising wrong deadlock warnings, fixed
here by a backport from 6.0-main.

include/my_pthread.h:
  Porting changes done to 6.0-main which satisfy the safe_mutex deadlock detector (those
  in 5.1-main don't), see chad@mysql.com-20090126155607-n0j3zbmgbfepnmmo for explanations
mysql-test/mysql-test-run.pl:
  adding back Serg's --list-options
mysys/my_init.c:

  in 5.1-main don't), see chad@mysql.com-20090126155607-n0j3zbmgbfepnmmo for explanations
mysys/my_thr_init.c:

There were so many changes into mtr (this is the new mtr coming) that I rather
copied mtr from 6.0-main here (at least this one knows how to run Maria tests).
I also fixed suite/maria tests to be accepted by the new mtr.

mysys/thr_mutex.c:
  adding DBUG_PRINT here, so that we can locate where the warning is issued.

it was bug in a test program, changed WT_THD's initialization to ensure they have no garbage from the previous run.
