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.
