#1592 closed defect (fixed)

bbPress Standalone Importer breaks if source forum is too big

Reported by: ali3n0 Owned by:
Milestone: 2.1 Priority: normal
Severity: normal Version:
Component: API - Importers Keywords: dev-feedback


Seems there's a memory leak somewhere, given that even growing allowed memory indefinitely it still breaks pretty much at the same point. You can see the error in the attachment

Is anyone with this problem willing/able to provide some database files to test this out? It would take some work to produce forum data of that magnitude manually. Alternatively, does anyone know of a plugin that one could use to create database info, similar to

I don't have a bbpress forum, but can provide a vbulletin forum db. Threads: 60,982, Posts: 295,135, Members: 26,800

We also have access to forums with 10million+ posts and 500k members if that would help.

*I've currently got one of the vb devs working on building me a vb importer for bbpress plugin. He built one for standalone and it worked perfectly on the larger db, still tweaking on the plugin importer.

  • Milestone changed from Awaiting Review to 2.1
  • Version 2.0 deleted

There is a redux of the migration tool in the works, along with migrators from several other popular forum packages.

Bumping to 2.1 so we can reevaluate this after 2.0.

I can provide database files for a 20k BuddyPress legacy (1.x) forum.

I know from jjj's previous comment that this is getting some work, but just in case, I had a thought. Change the foreach statements from

foreach( $topics as $topic )


foreach( $topics as $key => $topic )

and at the end of the foreach run

unset( $topics[$key] )

then for good measure, run

unset( $topics )

somewhere soon after the foreach.

This should help reduce memory usage as we chug along through the import.

@jjj, if you have no objections, and it's help is still needed on this, I'd be glad to work up a patch for testing.

  • Resolution set to fixed
  • Status changed from new to closed

First pass: replace bbPress 1.1 importer with bbConverter by Adam Ellis.

  • Handles large bbPress installations much better than original importer
  • Better potential for new converters in future
  • Breathes life into abandoned bbConverter project
  • See #1592
  • Props Adam Ellis for bbConverter
  • @todo: Settings/UI/code clean-up, shake vigorously, lather, rinse, repeat
