How did you update Flow exactly? Which git branch / revision?

Subfader added a comment.EditedOct 8 2016, 11:36 AM

I figured out I had not set $wgFlowContentFormat which defaults to "html" which requires Parsoid (T147712).

I don't use Parsoid, so I started all over again.

Setup before update

  • MW 1.27.1
  • All kind of extensions which were tested before, including the required Echo and ParserFunctions.
  • Memcached tested and working
  • Flow (REL1_27 2016-07-19T23:02:44 af307cc):
require_once "$IP/extensions/Flow/Flow.php";
$wgGroupPermissions['sysop']['flow-create-board'] = true;
$wgNamespaceContentModels[NS_USER_TALK] = CONTENT_MODEL_FLOW_BOARD;
$wgNamespaceContentModels[NS_PROJECT_TALK] = CONTENT_MODEL_FLOW_BOARD;
$wgFlowEditorList = array( 'none' );
$wgFlowMaxLimit = 50;
$wgFlowCacheVersion = 6;
$wgFlowContentFormat = null; // wikitext

Update

  1. Create DB from 1.25.1 dump
  2. php /.../maintenance/populateContentModel.php --ns=all --table=page > Sets all pages "to wikitext"
  3. php /.../extensions/Flow/maintenance/FlowUpdateRevContentModelFromOccupyPages.php > Set content model for 0 pages; skipped 0 pages.
  4. php /.../maintenance/update.php > Error at the end:

Page call

Calling a page where a flow board was added in MW 1.25.1 returns

Unknown topic
The requested topic does not exist.

Debug log for that single page call: P4180

This seems to be exactly the same problem as T110446#2613215 . Mark wrote a patch for that (linked from the task) which I merged; does your version of Flow include his patch?

No. I remain unable to update since August now because of 1.27 complications.

Shit is not stable.

@Subfader: Even if you may have reasons to be annoyed, a simple "Did not help, see T110446#2710317" would be sufficient. Thanks!
