Bug Description

When doing a partial streaming backup using xbstream, upon extracting the archive it reports the following error:
xb_stream_read_chunk(): wrong chunk magic at offset 0x1b3990e.

This error seems spurious to me because I am able to successfully prepare the backup without any issues.

The XtraBackup version is:
[root@centos6_01 backup_test]# xtrabackup --version
xtrabackup version 2.0.5 for Percona Server 5.1.59 unknown-linux-gnu (x86_64) (revision id: 499)

The Percona Server version is:
[root@centos6_01 backup_test]# /usr/sbin/mysqld --version
/usr/sbin/mysqld Ver 5.5.29-29.4 for Linux on x86_64 (Percona Server (GPL), Release rel29.4, Revision 401)

xb_stream_read_chunk(): wrong chunk magic at offset 0x1b3990e.

The MySQL datadir that is backed up is attached to the ticket.

The interesting thing to note is that if I take a complete dump of MySQL data using mysqldum, clean the MySQL datadir and import the dump and then run Xtrabackup, then the resultant archive is extracted without any error.

I was also able to get a sporadic failure on a full backup but I am not able to repeat it with full backups

This bug is fixed in 2.0.6.

Background: the fix for bug #711166 released in 2.0.5 had broken, among other things, partial streaming backups with multiple InnoDB tablespaces. XtraBackup erroneously printed the "Skipping <tablespace>" message to stdout rather than stderr. I noticed and fixed that while working on the fix for #1130627, though I did not report a separate bug for it.

I cannot reproduce this bug with the fix for #1130627, but I can reproduce it with that fix reverted.

So this bug is not reproducible with XB 2.0.6, though technically it's not a duplicate of bug #1130627, it's just been fixed with the same patch.

And the reason why the mentioned regression went unnoticed is that the XB test suite does not have any tests for this combination, i.e. partial streaming backups with multiple InnoDB tablespaces.

Let's keep this report to add such a test case.

summary:

- Streaming partial backup when extracted throws the error
- xb_stream_read_chunk(): wrong chunk magic at offset 0x1b3990e
+ Add a test case for partial streaming backups + multiple tablespaces
