Description

parser thinks two colons in a code block signify a definition list. Also the wiki engine may crash at some point, when an unordered list point follows this misinterpreted dl

Steps to reproduce

Have this code:

* not intending a {{{class

hello}}} definition list here

this point kills the parser

First, but minor severe it renders wrong, see also

• http://moinmo.in/MoinMoinBugs/List%20after%20Definitionlist

• http://moinmo.in/MoinMoinBugs/NumberedListFailsAfterDefinition

More importantly, do the following to make your engine crash:

1. edit in text mode
2. switch to GUI mode

3. switch back to edit mode -> internal server error 500, error raised in MoinMoin/converter/text_html_text_moin_wiki.py line 642 (1.9.4)

   • According to HTML standard, there must not be an ul in a dl (http://de.selfhtml.org/html/referenz/elemente.htm#dl). However, letting the engine crash with is a bit harsh (one might loose data).

Workaround

doesn't seem to be one

Even the "backtick" syntax doesn't help in this case:

 * not intending a `class :: hello` definition list here
 * this point kills the parser

Test:

* not intending a `class

hello` definition list here

this point kills the parser

I imagine that the problem is the "pattern hierarchy": quoted regions should conceal things like :: from patterns that cause definition lists to be produced, but maybe this isn't present in the part of the grammar dealing with lists, where once a line starting with a space and containing :: is seen, the parser just takes everything between as a definition title item without detecting whether the :: is quoted in some way. -- PaulBoddie 2013-03-01 13:07:31
