Upgrade:
- `gorm.io/gorm` v1.23.8 → 1.25.2
- `github.com/glebarez/go-sqlite` v1.17.3 → v1.8.0
- `github.com/glebarez/sqlite` v1.4.6 → v1.8.0
and also some indirect dependencies.
This is in the hope that some weird cases at Blender Studio get resolved.
It appears that sometimes, for some unknown reason, when deleting a job,
its tasks get reassigned to another job (instead of also getting deleted).
Since there is no code in Flamenco itself to do this task deletion (it's
all depending on SQLite following the foreign keys and cascading to tasks),
I hope it was a bug in either GORM or SQLite that got fixed at some point.
SQLite can return `SQLITE_BUSY` errors when it's doing too many things at
the same time. This is now improved a bit by setting a 5-second timeout,
during which the SQLite driver will wait for the database to become
available. If that doesn't happen, Flamenco Manager will return a
`503 Service Unavailable` response so that the client knows to back off
a little.
