All of the recent 5.3 builds in buildbot have two failures:
innodb_plugin.innodb_bug54044 'innodb_plugin' innodb_plugin.innodb_information_schema 'innodb_plugin'
The failure happens only with innodb_plugin. XtraDB is fine.
I've investigated the first problem. Its cause is in storage/xtradb/handler/ha_innodb.cc:get_innobase_type_from_mysql_type():
- On 2010-08-04, Kristian did a merge from XtraDB in Percona-Server-5.1.47-11 and among everything else pulled in the code that will produce error when the function's argument is Field_null. This seems to be the bugfix for BUG#54044
- On 2011-03-29, Sergei was making fix for lp:743017 in 5.1-micro, switched the function from analyzing field->type() to analyzing field->key_type() and in the process removed the part of code that Kristian has added. For some reason, he did that storage/innodb_plugin and storage/innobase but not to storage/xtradb.
Because my patch was in mysql-5.1, there was no xtradb there :)
- On May, 28th Monty has merged in Sergei's change into 5.3-main and we started to get the failure.
I see two problems here: P1: (the apparent one) Sergei's new code doesn't produce error when passed a Field_null object.
intentionally. I've fixed the test too, btw (in 5.1).
P2: (less apparent one) Why do we have Microsecond changes in innodb_plugin but not in xtradb? Could there be more fixes missing in a similar way?
Monty merged my changes into 5.3, but missed this particular detail, so xtradb and the test case were merged incorrectly. I can fix it on Monday (hopefully). Regards, Sergei
