Flow

This is a How-To guide on how to deal with installation and removal of Flow on the Wikis.

Installing Flow on a wiki

Do not do this. Flow is not eligible for deployment to more wikis.

Ensure that all Flow boards are either transwikied or exported to wikitext (with ConvertToText) and deleted.
Remove the wiki from flow.dblist (e.g. like this).
Delete all pages in the Topic namespace:
- Add $wgExtraNamespaces[2600] = 'Topic'; to the config (only locally on the deployment machine, don't sync this)
- Add $wgContentHandlers["flow-board"] = $wgContentHandlers["wikitext"]; to the config (only locally on the deployment machine, don't sync this)
- Run SELECT CONCAT('Topic:', page_title) AS page_title FROM page WHERE page_namespace=2600; and put the list of pages in a file
- Run mwscript deleteBatch.php --wiki=<dbname;ie: eswiki> -u='<your_sysadmin_username>' -r='Uninstalling Flow' list-of-topic-pages.txt
- Remove the added config.
