Description Barns 2007-10-23 17:57:26 UTC
MW seems to be handling unproperly the HTML definitions tags.

Entering:
<DL>
<DT>my definition header</DT>
<DD>
<UL>
<LI>Cameroon</LI>
<LI>Nigeria</LI>
<LI>Somalia</LI>
<LI>Sudan</LI>
</UL>
</DD>
</DL>

Will result in some tags being rendered as html special chars and show up in article rendering.
Comment 1 Joshua C. Lerner 2008-05-09 16:15:41 UTC
I'm seeing this as well on 1.11.0 - but not on Wikipedia (1.13alpha (r34478)).
Comment 2 Aryeh Gregor (not reading bugmail, please e-mail directly) 2008-05-09 16:58:06 UTC
This has probably been fixed at some point since 1.11.0.  If you can reproduce in 1.12, or preferably 1.13alpha, please reopen.

I don't know if this was working in 1.12 through 1.15, but i am definitely experiencing this problem in 1.16.


Steps to reproduce:

1. Create new article, edit existing article, whatever.

2. In body of article, create a simple definition list using the HTML syntax (not the colons and semicolons). Something like the following:

<dl>
<dt>test 1</dt>
<dd>test test test test test</dd>
<dt>test 2</dt>
<dd>test test test test test</dd>
</dl>

3. Save article.


Expected results:

The code above should appear more or less verbatim in the final article source.


Actual results:

The final article source (as seen in View > Source) looks like this:

<dl>

<dt>test 1&lt;/dt&gt;
<dd>test test test test test&lt;/dd&gt;
<dt>test 2&lt;/dt&gt;
<dd>test test test test test&lt;/dd&gt;
</dl>

As you can see, it insists on converting the closing tags to plain text, which results in '</dt>' and so on appearing in the rendered article. White space doesn't seem to come into it (for example i can put everything on one line and the same issue occurs).

This problem also seems to affect the closing tags of other HTML elements *inside* more advanced DLs. For instance, i have a DL that contains <div><code>...</code></div>, and the closing tags for the code/div elements are rendered similarly to the above.

I have reproduced this on two different MediaWiki installations on DreamHost; one has a few extensions/modifications installed, but the other is pretty much vanilla (all extensions disabled, no core files modified, no fancy settings in place).

Product Version
MediaWiki 1.16.0
PHP 5.2.15 (cgi-fcgi)
MySQL 5.1.39-log
Comment 4 Aryeh Gregor (not reading bugmail, please e-mail directly) 2011-01-05 22:30:17 UTC
Cannot reproduce in 1.18alpha.  Can anyone else test in 1.16.0 and see if they get the same problem?  I suspect it's configuration-dependent.
Comment 5 Platonides 2011-01-05 22:45:36 UTC
Confirmed in 1.16.0, REL1_17 and trunk. Passes if you have $wgUseTidy = true. Added failing parser test in r79679.
Comment 6 Aryeh Gregor (not reading bugmail, please e-mail directly) 2011-01-05 23:03:26 UTC
Typical.  I wish we could kill $wgUseTidy.

Fix pending in https://gerrit.wikimedia.org/r/#change,5174.
Comment 9 Antoine "hashar" Musso (WMF) 2012-10-25 17:40:13 UTC
Merged in, will be in MediaWiki 1.21.
