Percona Playback – new non official rpm for CentOS

Recently (yesterday), I faced a problem with percona-playback when I tried to use a slow query log (captured on a customer's server) and it fails dramatically. The log files was 2.3G and the second query was already returning an error :-(

I seemed that I hit a bug that Aurimas, my colleague at Percona, already reported (bug 1035217): queries written on multi lines don't work !

My C++ knowledge is very old and also very limited, so I tried to understand and fix this issue myself. Mushu (dbasquare) already faced this problem and started to fix it before giving up as he needed to run it on Slowaris... Gently he sent me his patch that I modified to support my slow query log:

  • queries on multi-lines
  • queries being only a ; (semi-colon)
  • queries finishing by another character than ; (with comments for example)

Attached to this post, you can find the rpm for CentOS 6 including that patch.

replication-booster and mysql-replication-listener rpm’s

As I wanted to test in my vagrant environment Yoshinori's MySQL replication booster, I needed to create rpms to be able to install it quickly and easily on those virtual machine without compiling it on the vm's.

So if you are interested in this nice replication solution and you are lazy to compile it, you can use my rpm's listed bellow.

Some links about the project:

mysql replication listener's rpm was built using modified specs from https://bitbucket.org/winebarrel/ruby-binlog/downloads

Update

I added the src.rpm as requested by nvidhive on #percona freenode.

sysbench 0.5 for CentOS 6

During my work I sometimes need to perform some benchmarks. I usually use sysbench. The version provided in EPEL for CentOS is old and I wanted to benefit from all the new features of the latest version from launchpad maintained by my colleague Alexey. But as I don't want to install bzr and devel packages and then recompile each time, I decided to make an rpm. I think some people could find it useful so I share it. Enjoy !

[update] I made a new package that also includes the lua files for db tests.

[update] New package from last bzr trunk where bug related to --tx-rate has been fixed (requested by my colleague Jay for his Percona Live New York tutorial about XtraDB Cluster
