You have XSS security to on. When importing with XSS : it take more memory. Can you activate debug mode. Surely memory issue. |
 |
Yes, surely memory issue. I turned the debug mode on and tried to copy a survey: Fatal error: Allowed memory size of 268435456 bytes exhausted (tried to allocate 81 bytes) in /var/www/limesurvey/framework/vendors/htmlpurifier/HTMLPurifier.standalone.php on line 12216 When I deactivate XSS filtering, then the problem disappears for normal users. (XSS is always off for superadmin, this is the thing). Well, is there any suggestion to solve the memory issue with XSS on? |

The code is here : But attention, we need a complete XSS filtering, not just filtering <script> ;) |

Many thanks! Anyway, I doubled the memory_limit in config.php. |

Memory issue |

When it needs more than double the size with xss on I think there is a problem. I succeeded as admin with 128mb, when doing it as a normal user 256mb was still not enough. When placing gc_collect_cycles(); in the question and subquestion routines the memory stays even within a 32mb limit. Don't have time to further investigate, but there is a serious leak somewhere. |

@mdekker : with gc_collect_cycles : memory reduced for admin too ? We force 5.3, then maybe it's a solution PS: maybe there are some caching in memory for XSS too ? |
|
|
I don't think that there is a leak. If it was then gc_collect_cycles() would NOT collect it. Anyway, if there is a issue it is inside HTMLPurifier, so lets just call gc_collect_cycles() once after purify(). I checked and it does not really add any processing time. |
