# Description

"<physikerwelt> Hi, I have created a new version of the Math extension that allows displaying mathml using the latexml converter instead of rendered images. Furthermore I have created a test wiki that contains all pages of the English Wikipedia Project that contain math. Now I’d be interested to test this feature inside the Wikimedia framework. Do you have a proposal how to do that."

Version: master
Severity: normal

All tests pass! With the installation of 'texlive-lang-greek' and 'texlive-fonts-recommended', I was able to get 12/13 tests to pass. The remaining test failure was due to the srset attribute getting added to img tags, so I updated the expected output.

I documented the dependencies in README.

Merged. Thanks very much physikerwelt for your patience and fixes and thanks Matt for the reviews. This is now in the deployment queue.

I'm not totally comfortable with the change from nullLockManager to fsLockManager (https://gerrit.wikimedia.org/r/#/c/30177/20..24/MathTexvc.php).

In theory it should be okay on the WMF cluster, since it looks like it only applies if wgMathFileBackend is not set.

In mediawiki-config, there is:

$wgMathFileBackend =$wmgMathFileBackend;

in CommonSettings.php

and:

'wmgMathFileBackend' => array(
'default' => 'global-multiwrite'
),

in LocalSetting.php.

However, it could affect other installations.

This is for background on the lock manager discussion.

I've recommended that physikerwelt squash some of the commits on the branch, so there won't be quite so many to review.

Thanks a lot Matthew. I want to do some meaningful unit tests for the module. I would be quite happy if you could provide some input for that task. Is there a general stategy at the WMF to structured tests. In the end we should come up with a mutually orthogonal set of tests, some integration tests in addition and furthermore tests that check for the expected bugs.
Thus I'd be happy to collect a list of required test at
After that the time is ready for merge.

Generally we have parser tests, which you've already seen, PHPUnit tests (can be used for unit or integration tests on server), QUnit (JavaScript unit tests), and Cucumber for integration tests (testing the overall user experience through the web browser).

Probably, PHPUnit would be most important for your stuff, but if you want to add some QUnit or Cucumber, that would be a bonus, particularly for the MathJax stuff.

I've done a lot of QUnit here, and some PHPUnit, so I can definitely help with those. I'm working on a Cucumber test right now, but I haven't committed anything yet.

Maybe to be more precise. Is there a prototpe extension that comes up with good unit tests. Especially the database stuff is something that is not trival to test.

There probably are extensions with good database tests, but I can't pinpoint one offhand. However, if you go into the test directory of MediaWiki core, you can do:

git grep db

That will give you an indication of how databases are used for core tests. Extension tests generally subclass the same class, MediaWikiTestCase, which provides some of the database functionality you'll need.

Thanks.
I tried to figure out how to set up the database tables for testing. As far as I did understand there must be a way to clone the table structure with a prefix.
However if I tied to do this, I get a warning the table "_prefix_math" does already exist.

Unfortunately there are some bugs in the master version. Is there a way to get them fixed faster than the via the normal review process.

It would be grate to be able to test LaTeXML in the context of the WMF.
see
https://wikitech.wikimedia.org/wiki/New_Project_Request/Math

I think it is very important to do tests there before committing something to the main branch.

I pinged the Wikimedia Labs mailing list (https://lists.wikimedia.org/mailman/listinfo/labs-l), and Daniel Zahn created it.

Patch merged on 2013-05-26. What's the next steps?

Since mathml is not supported by manny browseres
This change is also important to reach a wide audience

There is still an open LaTeXML branch (https://git.wikimedia.org/log/mediawiki%2Fextensions%2FMath.git/refs%2Fheads%2FLaTeXML), with recent commits

However, I'm not sure if this bug is still helpful. Commits to master are being reviewed on a case-by-case basis.

physik wrote:

Since LaTeXML is merged and there are some users that use it actively this bug can be closed. Unfortunately I can not do that;-)

To avoid confusion I deleted the LaTeXML branch and renamed it to dev.

Just as information: The next step towards MathML are the deployment of the LaTeXML package. operations/debs/latexml

Marked fixed. :)

Do you have editbugs yet? If not, you can ask on IRC for someone to give it to you.
