MDEV-6506: InnoDB: Assertion failure in thread 2810182464 in file
buf0flu.cc line 549.

Analysis: If buf_page_get_state(bpage) == BUF_BLOCK_REMOVE_HASH then
buf_page_in_file(bpage) might not be true.

Fix: ut_a(buf_page_in_file(bpage) || buf_page_get_state(bpage) == BUF_BLOCK_RE
MOVE_HASH);

Looks like https://bugs.launchpad.net/percona-server/+bug/1305364, which applies to 5.5 as well, and is fixed in XtraDB 5.5.37-35.1/5.6.17-66.0.

Are you seeing it with a newer XtraDB version than those above?

Comment by Jan Lindström (Inactive) [ 2014-07-31 ]

Hi, this was repeatable with Percona XtraDB (http://www.percona.com) 5.6.17-65.0 and with modified version of Facebook's patch to simulate compression failures https://github.com/facebook/mysql-5.6/commit/bce56ed93e4bfa06f845b7b98e78b9ab6281bdfc

But not very easily repeatable, I can't repeat on my machine.

OK, it's indeed LP 1305364 then, and you'll have a complete fix once you merge the corresponding 5.5/5.6.

Comment by Jan Lindström (Inactive) [ 2014-08-01 ]

True, your fix seems better and will be part of 5.5.39 release.
