are the required packages installed already? a grep for lilypond in puppet(production) does not show anything.

Adding Tim to this issue since he is the most familiar with the extension and what it needs and what we have.

Hey Jan,

Could you write up a puppet config for this (lilypond specifically and anything else Score-related/dependent) and submit it for review in Gerrit?

Thanks!

puppet config pending review at https://gerrit.wikimedia.org/r/#/c/56577/

That change is now merged. lilypond is now installed on all the mediawikis.

However, the same error message is still there on the /Score page. I even made a simple edit to the markup to force a regen.

Thoughts, Jan?

		$cmd = wfEscapeShellArg( $wgScoreLilyPond )
			. ' ' . wfEscapeShellArg( '-dsafe=#t' )
			. ' -dbackend=eps --png --header=texidoc '
			. wfEscapeShellArg( $factoryLy )
			. ' 2>&1';
		$output = wfShellExec( $cmd, $rc2 );
		$rc = chdir( $oldcwd );
		if ( !$rc ) {
			throw new ScoreException( wfMessage( 'score-chdirerr', $oldcwd ) );
		}
		if ( $rc2 != 0 ) {
			self::throwCallException( wfMessage( 'score-compilererr' ), $output, $options );
		}

I guess giving the return code could be helpful. And even an error message..

the problem is that on the apache nodes $wgMaxShellMemory is 100 Mb ($wgMaxShellMemory = 102400;) but lilybond only works with more memory.

this can be fixed buy switching to the ps backend (https://gerrit.wikimedia.org/r/58512)

to support vorbis generation, we also need to install timidity
