Description:
HTML-Code from the errorpage

If a Page has a lot of '<' or '>' the following error code were given

Fatal error: Allowed memory size of 67108864 bytes exhausted (tried to allocate 339607 bytes) in /users/lastchaos/www/includes/Sanitizer.php on line 554

The Usage of memory is temporary more than 256MB but the problem is allready exsisting. In the content we use a lot of HTML-code and the '<' and '>' tag is used in this article more than 70.000 . I don't know, why this error should be happened, but it isnt working since the 1.21 version. Additionally the Server working with php version 5.5.

Another page, which includes a lot of <img>-Tags are present the same error but with an plugin while i submit it:
Fatal error: Allowed memory size of 67108864 bytes exhausted (tried to allocate 264175 bytes) in /users/lastchaos/www/extensions/TinyMCE_MW/TinyMCE_MW.php on line 297
In the attachment is the HTML-Code from the first page.

Furthermore the TinyMCE don't work with the newest php version (5.5) because the headlins dont change to the <h2> or other <hx>-HTML-Tags.

In my opinion the TinyMCE Extension is the cause for the Bugs. If i disable this extension all pages can be submitted and shown. Maybe the TinyMCE Extension should be updated for the newest WediaWiki version.

Could you enable $wgShowExceptionDetails ?

Is that a different problem? If yes, could you please file a separate bug report (again, a minimal testcase or good steps to reproduce are welcome)? Thanks.

For the TinyMCE_MW heading problem is another bug report:

I hope this bug report is better :)

Another important information:

I debuged the submit action like the Debug information.txt in the attachment. The function Parser::replaceVariables is called very often. If I comment the function between wfProfileIn( METHOD ); and wfProfileOut( METHOD ); the large site would be saved. If the function is non-comment the large site didn't saved and I get the error. Maybe this could be the problem.

Furthermore I rework the HTML code of the page and now i dont get any problem, only a blank page, if i submit the page. The HTML code is a little bit smaller as the first (~80kB). But the submit problem still appear.

Is this actually a bug where something worked in PHP 5.3 but broke in 5.5+? It doesn't seem that the underlying issue is, just the bit broken out into T52928: TinyMCE_MW Extension don't handle headings with php 5.5. Problem with Hook ParserAfterTidy

This is an ancient task referring to a prior incarnation of the TinyMCE extension which I believe is no longer valid for the current version.
