#4239 closed defect (bug) (fixed)

PREG_BACKTRACK_LIMIT_ERROR encountered during WP import

Reported by: ryan Owned by: ryan
Milestone: 2.2 Priority: normal
Severity: normal Version: 2.2
Component: Administration Keywords: wxr importer preg
Focuses: Cc:


The WordPress importer uses preg_match_all to slurp items from the import file. Large items can cause a PREG_BACKTRACK_LIMIT_ERROR. This can be avoided by bumping pcre.backtrack_limit, but that isn't very friendly. Instead, the importer shouldn't use preg_match_all. There are other ways of retrieving the items.

Testing went well, so I committed for 2.2 since this bug sucks for those affected.
