+This directory contains patches that need to be applied to the MySQL
+source tree in order to get the mysql-test suite to succeed (when
+storage/innobase is replaced with this InnoDB branch). Things to keep
+in mind when adding new patches here:
+
+* The patch must be appliable from the mysql top-level source directory.
+
+* The patch filename must end in ".diff".
+
+* All patches here are expected to apply cleanly to the latest MySQL 5.1
+  tree when storage/innobase is replaced with this InnoDB branch. If
+  changes to either of those cause the patch to fail, then please check
+  whether the patch is still needed and, if yes, adjust it so it applies
+  cleanly.
+
+* If applicable, always submit the patch at http://bugs.mysql.com and
+  name the file here like bug%d.diff. Once the patch is committed to
+  MySQL remove the file from here.
+
+* If the patch cannot be proposed for inclusion in the MySQL source tree
+  (via http://bugs.mysql.com) then add a comment at the beginning of the
+  patch, explaining the problem it is solving, how it does solve it and
+  why it is not applicable for inclusion in the MySQL source tree.
+  Obviously this is a very bad situation and should be avoided at all
+  costs, especially for files that are in the MySQL source repository
+  (not in storage/innobase).
+
+* If you ever need to add a patch here that is not related to mysql-test
+  suite, then please move this directory from ./mysql-test/patches to
+  ./patches and remove this text.

+The partition_innodb test only fails if run immediately after innodb_trx_weight.
+The reason for this failure is that innodb_trx_weight creates deadlocks and
+leaves something like this in the SHOW ENGINE INNODB STATUS output:
+
+  ------------------------
+  LATEST DETECTED DEADLOCK
+  ------------------------
+  090213 10:26:25
+  *** (1) TRANSACTION:
+  TRANSACTION 313, ACTIVE 0 sec, OS thread id 13644672 inserting
+  mysql tables in use 1, locked 1
+  LOCK WAIT 4 lock struct(s), heap size 488, 3 row lock(s)
+  MySQL thread id 3, query id 36 localhost root update
+
+The regular expressions that partition_innodb is using are intended to extract
+the lock structs and row locks numbers from another part of the output:
+
+  ------------
+  TRANSACTIONS
+  ------------
+  Trx id counter 31D
+  Purge done for trx's n:o < 0 undo n:o < 0
+  History list length 4
+  LIST OF TRANSACTIONS FOR EACH SESSION:
+  ---TRANSACTION 0, not started, OS thread id 13645056
+  0 lock struct(s), heap size 488, 0 row lock(s)
+  MySQL thread id 8, query id 81 localhost root
+
+In the InnoDB Plugin a transaction id is not printed as 2 consecutive
+decimal integers (as it is in InnoDB 5.1) but rather as a single
+hexadecimal integer. Thus the regular expressions somehow pick the wrong
+part of the SHOW ENGINE INNODB STATUS output.
+
+So after the regular expressions are adjusted to the InnoDB Plugin's variant
+of trx_id prinout, then they pick the expected part of the output.
+
+This patch cannot be proposed to MySQL because the failures occur only
+in this tree and do not occur in the standard InnoDB 5.1.
