Bug Description

After rebasing XB on Percona-Server-5.5.31-rel30, the bug891496.sh test fails as follows:

http://jenkins.percona.com/view/XtraBackup/job/percona-xtrabackup-2.1-param/382/BUILD_TYPE=release,Host=debian6-64,xtrabackuptarget=galera55/testReport/junit/%28root%29/t_bug891496/sh/

The test does a fairly basic thing:

1. It starts the server with innodb_data_file_path=ibdata1:3M;ibdata2:10M:autoextend
2. Takes a streaming backup
3. Prepares and restores.
4. Then starts the server. At this point Percona-Server-5.5.30-rel30.1 starts up just fine, but PXC 5.5.31-23.7.5 crashes on startup.

I'll see if PS 5.5.31 crashes in the same way. If not, it looks like a PXC bug. Assigning to Raghu for now to check if it looks familiar.

Nothing related I can think of, I don't see any debug symbols either, so I need to reproduce this locally.

I have fixed one another bug in another lp issue, lets see if this fixes that.

So, I was able to get following backtrace on trunk build of PXC:

0x52bc9d _start + 41

However, this is same as the multi ibdata1 regression's backtrace.

Next, I tried a build from lp:~percona-core/percona-xtradb-cluster/percona-xtradb-cluster-for-xtrabackup-tests/

and it passed.

==============

(I used binaries from http://jenkins.percona.com/job/percona-xtrabackup-2.1-binaries/label_exp=centos6-64/ for this)

Hence, I suspect an old 5.5.32 build (and not lp:~percona-core/percona-xtradb-cluster/percona-xtradb-cluster-for-xtrabackup-tests/
) may have been used/caused for this crash.

Raghu,

Thanks, I will check what's actually being used there.

Yes, it is not failing here http://jenkins.percona.com/view/XtraBackup/job/percona-xtrabackup-2.1-param/BUILD_TYPE=release,Host=debian6-64,xtrabackuptarget=galera55/393/

(the xb_galera_sst socat issue should be fixed in puppet by now).
