v9.94 2026-07-15 WeKan ® release

This release adds the following new features:

• Snap: the database setting is now authoritative, with a snap run wekan.database mongodb|ferretdb command and no-downtime handling of a failed migration (snap-src/bin/wekan-database, snap-src/bin/wekan-control, snap-src/bin/mongodb-control, snap-src/bin/ferretdb-control, snap-src/bin/migration-control, snap-src/bin/migration-pending). Previously the control scripts force-switched to FerretDB whenever a *.sqlite file existed, so snap set wekan database=mongodb would not stick and there was no way to keep WeKan on MongoDB while fixing a migration — a failed migration meant downtime. Now the database setting decides which database WeKan runs on, and snap run wekan.database mongodb switches WeKan to MongoDB (and pauses auto-migration, migrate=off) while snap run wekan.database ferretdb switches to the migrated FerretDB. Auto-migration can be paused with snap set wekan migrate=off and, crucially, a migration that FAILS now pauses itself and hands back to MongoDB automatically (migration-control fail_and_run_mongodb) so WeKan keeps working on MongoDB instead of retrying-and-failing every start; re-run it with snap run wekan.migrate. A successful migration also restarts wekan.wekan so it reconnects to FerretDB. The only remaining auto-override is the safety guard that refuses to start an empty FerretDB while MongoDB still holds data. Thanks to xet7.

and fixes the following bugs:

• Snap: the MongoDB → FerretDB migration failed on GridFS collections and left a half-migrated database behind (releases/migrate-mongodb-to-ferretdb.mjs, snap-src/bin/migrate-mongo3-to-ferretdb.mjs, snap-src/bin/migration-control). FerretDB v1 rejects collection names containing a dot (“invalid key: ‘attachments.chunks’ (key must not contain ’.’ sign)”), and the importers tried to copy the GridFS internals collections (attachments.chunks, attachments.files, avatars.*, cfs_gridfs.*) and the CollectionFS cfs.<bucket>.filerecord collections as text, so the migration aborted. Now the text phase skips every dotted collection — none of WeKan’s real data collections contain a dot, and the dotted ones are all GridFS internals (extracted in the file phase), CollectionFS filerecords (turned into bare attachments/avatars records in the file phase, now created with an upsert) or system.* collections. And crucially, when a migration fails partway it now deletes the partial FerretDB SQLite it wrote (migration-control’s discard_partial_ferretdb): otherwise that non-empty-but-incomplete files/db/wekan.sqlite looked “migrated” to the data check, so the snap disabled MongoDB and tried to serve an incomplete FerretDB. Now a failed migration cleanly keeps MongoDB and retries. Thanks to xet7.
