Partial fix Too many quotes

[rellek]

Hi,

an error was logged at my forum:

ErrorException: Fatal Error: Maximum function nesting level of '100' reached, aborting! - library/XenForo/BbCode/Formatter/Base.php:479

I'm not exactly sure but I think there are too many quotes. I think it'd be better if the parser would just ignore this whole bunch of nestes BBCodes instead of throwing a blank page...

This sounds more like a suggestion.

 

[rellek]

I think a blank page on the user's view is more like a bug, since there's no obvious possibility to fix that either. It doesn't even state which postid contains the many quotes.

Not really, Amaury.

Anything in the software that can cause a server error should be treated as a bug as there's nearly always graceful ways of preventing it getting to an error state.

Fair enough.

I only said that because of this:

I think indicates a suggestion to me.

 

[rellek]

This was kind of a suggestion how "I" would fix that. But this is just my opinion, maybe Mike or Kier have a better idea.

In case it helps... This is the post that makes problems:

Maximum function nesting level of '100' reached

I was going to ask whether you had edited the code to nest quotes, or do members manually nest them?

Well, it was posted a long time ago, it was in 2005 when we used Burning Board 2.3. I guess the author wanted to create this effect:
http://xenforo.com/community/threads/just-a-test.58672/

This is kinda weird, the problem does not happen here. In my forum, I am unable to re-post this message. It just happens nothing - however an error is logged.

This also occurs more commonly if a large number of spoiler tags are nested (via custom bbcode addon)

Should be considered a core issue as you can basically DoS an entire thread page using this - the only way to access it again is to edit the post in the database

It's worth pointing out that this fatal error is trigged by xdebug and is not a limit in PHP itself. There are recursion limits, though they're likely to be significantly deeper than 100 PHP calls - just for reference, Python's default limit is 1000. You should increase this limit in xdebug.

That said, I am looking at a depth limit. I "only" see a depth of 20 tags there.

 

[rellek]

Thanks, disabling xdebug (whyever I installed it in the first place) fixed that

You should disable xdebug on your live system


Edit: Sorry, hadn't seen the last reply^^

Certainly an interesting thread you have there.
