+#
+# Bug#56632: ALTER TABLE implicitly changes ROW_FORMAT to COMPRESSED
+# http://bugs.mysql.com/56632
+#
+# Innodb automatically uses compressed mode when the KEY_BLOCK_SIZE
+# parameter is used, except if the ROW_FORMAT is also specified, in
+# which case the KEY_BLOCK_SIZE is ignored and a warning is shown.
+# But Innodb was getting confused when neither of those parameters
+# was used on the ALTER statement after they were both used on the
+# CREATE.
+#
+# This will test the results of all 4 combinations of these two
+# parameters of the CREATE and ALTER.
+#
+#    Tests 1-5 use INNODB_STRICT_MODE=1 which returns an error
+#    if there is anything wrong with the statement.
+#
+# 1) CREATE with ROW_FORMAT=COMPACT & KEY_BLOCK_SIZE=1, ALTER with neither.
+#    Result; CREATE; fails with error ER_CANT_CREATE_TABLE
+# 2) CREATE with ROW_FORMAT=COMPACT, ALTER with KEY_BLOCK_SIZE=1
+#    Result; CREATE succeeds,
+#            ALTER quietly converts ROW_FORMAT to compressed.
+# 3) CREATE with KEY_BLOCK_SIZE=1, ALTER with ROW_FORMAT=COMPACT
+#    Result; CREATE quietly converts ROW_FORMAT to compressed,
+#            ALTER fails with error ER_CANT_CREATE_TABLE.
+# 4) CREATE with neither, ALTER with ROW_FORMAT=COMPACT & KEY_BLOCK_SIZE=1
+#    Result; CREATE succeeds,
+#            ALTER; fails with error ER_CANT_CREATE_TABLE
+# 5) CREATE with KEY_BLOCK_SIZE=3 (invalid), ALTER with neither.
+#    Result; CREATE; fails with error ER_CANT_CREATE_TABLE
+#
+#    Tests 6-11 use INNODB_STRICT_MODE=0 which automatically makes
+#    adjustments if the prameters are incompatible.
+#
+# 6) CREATE with ROW_FORMAT=COMPACT & KEY_BLOCK_SIZE=1, ALTER with neither.
+#    Result; CREATE succeeds, warns that KEY_BLOCK_SIZE is ignored.
+#            ALTER succeeds, no warnings.
+# 7) CREATE with ROW_FORMAT=COMPACT, ALTER with KEY_BLOCK_SIZE=1
+#    Result; CREATE succeeds,
+#            ALTER quietly converts ROW_FORMAT to compressed.
+# 8) CREATE with KEY_BLOCK_SIZE=1, ALTER with ROW_FORMAT=COMPACT
+#    Result; CREATE quietly converts ROW_FORMAT to compressed,
+#            ALTER succeeds, warns that KEY_BLOCK_SIZE is ignored.
+# 9) CREATE with neither, ALTER with ROW_FORMAT=COMPACT & KEY_BLOCK_SIZE=1
+#    Result; CREATE succeeds,
+#            ALTER succeeds, warns that KEY_BLOCK_SIZE is ignored.
+# 10) CREATE with KEY_BLOCK_SIZE=3 (invalid), ALTER with neither.
+#    Result; CREATE succeeds, warns that KEY_BLOCK_SIZE=3 is ignored.
+#            ALTER succeeds, warns that KEY_BLOCK_SIZE=3 is ignored.
+# 11) CREATE with KEY_BLOCK_SIZE=3 (invalid), ALTER with ROW_FORMAT=COMPACT.
+#    Result; CREATE succeeds, warns that KEY_BLOCK_SIZE=3 is ignored.
+#            ALTER succeeds, warns that KEY_BLOCK_SIZE=3 is ignored.

storage/innobase/mysql-test/patches/README

-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.

storage/innobase/mysql-test/patches/index_merge_innodb-explain.diff

-InnoDB's estimate for the index cardinality depends on a pseudo random
-number generator (it picks up random pages to sample). After an
-optimization that was made in r2625 the following EXPLAINs started
-returning a different number of rows (3 instead of 4).
-
-This patch adjusts the result file.
-
-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. Furthermore,
-the file index_merge2.inc is used by other engines too.

storage/innobase/mysql-test/patches/partition_innodb.diff

-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.
