LP #1080829: Using xtrabackup sst fails due to mktemp error

Description

**Reported in Launchpad by MentalPower last update 31-05-2013 18:04:57

Whenever a joining cluster node tries to join a cluster and its setup to do so via SST it will fail due to an issue when calling the mktemp helper program.

Older versions of mktemp allowed trailing characters after the string of XXXXXX for the template. Version 7.4 does not and exits with an error of "mktemp: too few X's in template `wsrep_sst_xtrabackupXXXX.pid'" if you try. Newer versions have a --suffix option to address this, but that is not an option on a default ubuntu 10.04 system.

We're fixing the issue manually by changing line 118 in wsrep_sst_xtrabackup from "XTRABACKUP_PID=$(mktemp --tmpdir wsrep_sst_xtrabackupXXXX.pid)" to just "XTRABACKUP_PID=$(mktemp --tmpdir wsrep_sst_xtrabackupXXXX)"

Environment

None

Joe, please try an updated wsrep_sst_xtrabackup - https://launchpad.net/codership-mysql/5.5/5.5.28-23.7/+download/wsrep_sst_xtrabackup

The very idea of using mktmp turned out to be wrong.

Alex,

We have same problem when deploy on SuSE Enterprise Linux 11 SP2 (x86_64). (Install from source)

But it is strange the problem doesn't happen when deploy the same thing inside virtualbox with the same Linux OS and patch level.

@Alex,

I tested and yes, you need to kill both.

Alex,

You can read a difference there

We need to kill both of them if a caller died.

Done
