Re: Lilypond as MediaWiki extension does not print in Extension:Collection
2010/1/27 Oscar van Dillen oscarvandil...@gmail.com: on my website I found that Lilypond as MediaWiki extension does not print music notation, just code, to the pdf in Extension:Collection http://www.mediawiki.org/wiki/Extension:Collection Lilypond does work fine when using printable version such as can be seen here http://www.oscarvandillen.com/Triad?printable=yes should I rather tell the collection programmers at http://www.mediawiki.org/wiki/Extension:Collection/Wishlist Yes, please. If that extension shows only the LilyPond source code of snippets but the normal page view and the printable view show these snippets processed and converted to PNG, it surely means that LilyPond is not called to process these snippets from Extension:Collection.

Many people would love to use this extension in Wikipedia and other large-footprint wikis that they have no control over. However, in its current form, this is unfortunately impossible due to security concerns. This extension is using Lilypond's safe mode, which according to the documentation does not detect resource overuse. It is still possible to make the program hang indefinitely, for example by feeding cyclic data structures into the backend. Therefore, if using LilyPond on a publicly accessible webserver, the process should be limited in both CPU and memory usage. This extension is therefore not used in Wikipedia because it is considered a hazardous denial-of-service vector. is this correct, that lilypond has this security issue as stated; and is it possible to make the program hang indefinitely? thanks in advance and all the best, oscar -- oscarvandil...@gmail.com www.oscarvandillen.com ** The information contained in this message is confidential and may be legally privileged.

Re: Lilypond as MediaWiki extension does not print in Extension:Collection
Hi Oscar,
is this correct, that lilypond has this security issue as stated;
I'm no security expert, but this issue has been discussed at length several
times on the Lilypond lists (-user and -dev), so check the archives.
and is it possible to make the program hang indefinitely?
Probably... what about
\repeat unfold 1000 { \repeat unfold 1000 { \repeat unfold
1000 { \repeat unfold 1000 { c128 } } } }
Worse, of course, is to write in a Scheme function -- which Lilypond would of
course attempt to execute -- which simply calculated pi to infinite precision.
=)

Kieren

Best, John thank you kieren and john, things have become much more clear to me after this thread so far. i will ponder on how to perhaps make it run a bit more safely on my website, and keep on using it, as lilypond is relatively userfriendly, very powerful, and essential there :-) fyi to the pediapress people i wrote, to conclude ticket #775 i mentioned earlier: still, in my humble opinion, not including lilypond in the pdf rendering extension:collection is a missed chance for pediapress as well, since to me it seems to concern its field of business, and a possible venture into a whole new field: open source music printing. but i will not push the issue further at this point (and leave this ticket closed). i think however pediapress is missing out on an opportunity, but this is also a matter of choices of priority, and we may vary in this of course. i personally believe it would be more than worth the efforts to tackle this all the best, oscar -- oscarvandil...@gmail.com www.oscarvandillen.com ** The information contained in this message is confidential and may be legally privileged.

Mediawiki extension
Hello, I have some problems on a setup with Debian + Mediawiki + Lilypond. I installed it according to http://www.mediawiki.org/wiki/Extension:LilyPond I have Debian stable (Etch), Lilypond 2.8.7. Then I had to upgrade Lilypond to 2.10.29 (Debian testing) and guile to 1.8.2 (Debian unstable). I copied some Lilypond files from some other sites, including lilypond.org, but they do not work out of the box. Simple examples work, but complex ones do not. There are many syntax errors. See http://www.wikilivres.info/wiki/index.php/Musique_de_Table http://www.wikilivres.info/wiki/index.php/Down_to_the_Sea http://www.wikilivres.info/wiki/index.php/Belle_qui_tiens_ma_vie Help very much appreciated. However the result is quite nice when it works: http://www.wikilivres.info/wiki/index.php/Wikilivres:Lilypond Seeing the difficulties I have to set up Lilypond with Mediawiki, I understand why the developers of the Wikimedia Foundation refuse to enable it on Wikipedia and related projects. That's quite a pity, because it would be very useful there.

2007/7/16, Bertalan Fodor [EMAIL PROTECTED]: I remember there was a MediaWiki extension for lilypond. Does that exist currently? I'm creating a wiki site for some music and would like to use mediawiki along with this extension. You're refering to Johannes Schindelin's Wikitex extension: http://wikisophia.org/wiki/Wikitex http://svn.wikitex.org/wikitex/branches/1.1/template/music.ly AFAIK, this extension is unmaintained so far, but it should still work (maybe with some tweaking though). However, I think you need to install (in jailed mode) LilyPond on the same server where your wiki is hosted to use it. If you have to deal with many scores but no text, you can of course use Sebastiano's LSR backend, wich is by far the most advanced client/server LilyPond project. A French guy named Christophe Richard has just opened a public LilyPond server: http://www.lilyserv.net/bashserver.php He's using it with a Wiki-like plugin he has developed for the SPIP CMS: http://www.musicorum.net/spip.php?article125 (I know you disagree with the idea of creating new LilyPond clients, but I'd like to mention here the web interface I'm trying to develop, as an AJAX implementation of LilyPondTool, at http://valentin.villenave.info/lilypond/ ; currently it's only supported by Mozilla browsers) and btw, I'm glad to see I'm not the only Web2.0 geek here :) Regards, Valentin ___ lilypond-user mailing list lilypond-user@gnu.org http://lists.gnu.org/mailman/listinfo/lilypond-user
