PHP errors - preg_match_all(): Compilation failed

[Adrian Nabarro]

Hi there

While trying to import a lot of data (about 20,000 leads) the system dies after about 100 with the following error:

WARNING: [2] preg_match_all( Compilation failed: unrecognized  character after (? at offset 257 on line 1799 in file  /var/www/sugar/include/utils.php

The apache logs are full of a similar error:

Tue Feb 07 12:20:30 2012] [error] [client xxx.xxx.xxx.xxx] PHP Warning:  preg_match_all(): Compilation failed: unrecognized character after (? at offset 257 in /var/www/sugar/include/utils.php on line 1799

Any ideas what might be causing these?

Thanks in advance.

More than likely has something to do with this

PHP Warning: preg_match_all(): Compilation failed: unrecognized character after (?< at offset | Web and Technology

Thanks kbrill!

I did the fix recommended here:

... and that seemed to do the trick!

Would you suggest revert to the original file and instead update pcre?

I'd just like to add to this for anyone else having this issue.

After updating to 6.4GA the issue returned, which suggests there IS a typo in the utils.php file.

Thankfully, the solution is rather simple (thanks to the kind folks linked in that Google+ post):

On line 1788 change

$attribute_regex        = "#\b({$jsEvents})\s*=\s*(?|(?!['\"])\S+|['\"].+?['\"])#sim";

To

$attribute_regex        = "#\b({$jsEvents})\s*=\s*(?!(?!['\"])\S+|['\"].+?['\"])#sim";

Basically, change ?| (pipe) to ?!. Hope that helps!

I will ask our engineering department about this and submit a bug if they agree.
