MTR tests from binary tarball don't work out of the box: fail to find mysqldumpslow

[Elena Stepanova]

I download Percona-Server-5.1.68-rel14.5-513.Linux.x86_64.tar.gz,
unpack it,
cd Percona-Server-5.1.68-rel14.5-513.Linux.x86_64/mysql-test
run MTR and expect the tests to work, but they don't:

/data/releases/Percona-Server-5.1.68-rel14.5-513.Linux.x86_64/mysql-test$ perl ./mysql-test-run.pl main.1st
Logging: ./mysql-test-run.pl main.1st

worker[1] Using MTR_BUILD_THREAD 300, with reserved ports 13000..13009
worker[1] mysql-test-run: *** ERROR: Could not find /data/releases/Percona-Server-5.1.68-rel14.5-513.Linux.x86_64/scripts/mysqldumpslow
mysql-test-run: *** ERROR: Test suite aborted

Which is understandable, since mysql-test-run.pl insists on finding mysqldumpslow in 'scripts':

grep mysqldumpslow mysql-test-run.pl
  $ENV{'MYSQLDUMPSLOW'}= mtr_script_exists("$basedir/scripts/mysqldumpslow");

while mysqldumpslow is in fact in <basedir>/bin, and there is no <basedir>/scripts in the package at all.

5.5 is not affected, MTR doesn't look for mysqldumpslow there.

Maybe I'm missing something, but the simplest workaround I found was to create a link <basedir>/scripts => <basedir>/bin .

Confirmed. This is also happening in RPM files, and in general anytime that scriptsdir is defined to anything other than basedir/scripts/.

While the symlink solution seems straightforward, I wouldn't like to pollute /usr/ by adding a scripts symlink there. Seems that the problem is that $basedir/scripts/ is hardcoded into mysql-test-run.pl.

I think patching mysql-test-run.pl would be the best option here, and un-hard-code $basedir/scripts/. Thoughts?

Ignacio -

Patching mysql-test-run.pl looks OK fix.
