SQLite doesn't handle timezones by default, when you just use something
like `date1 < date2`, for example. This makes GORM explicitly use UTC
timestamps for the `CreatedAt`, `UpdatedAt`, and `DeletedAt` fields.
Our own code should also use UTC when saving timestamps. That way all
datetimes in the database are in the same timezone, and can be compared
naievely.
Check for jobs in 'cancel-requested' or 'requeued' statuses, and ensure
they transition to the right status. This happens at startup, before
even starting the web interface, so that a consistent state is presented.
When the job status changes, it impacts the task statuses as well. These
status changes are now no longer done with a single database query, but
instead each affected task is fetched, changed, and saved. This unifies
the regular & mass updates to the tasks, and causes the resulting task
changes to be broadcast to SocketIO clients.
The add-on code was copy-pasted from other addons and used the GPL v2
license, whereas by accident the LICENSE text file had the GNU "Affero" GPL
license v3 (instead of regular GPL v3).
This is now all streamlined, and all code is licensed as "GPL v3 or later".
Furthermore, the code comments just show a SPDX License Identifier
instead of an entire license block.
The root cause was a 2nd `context.Context()` that was used in
`constructTestJob()`, which cancelled when that function returned.
The cancellation of the context caused an interrupt in the SQLite
driver, which got into a race condition and could cause an interrupt on
a subsequent database query.
The on-disk database that was used before caused issues with tests running
in parallel. Not only is there the theoretical issue of tests seeing each
other's data (this didn't happen, but could), there was also the practical
issue of one test running while the other tried to erase the database file
(which fails on Windows due to file locking).
Some parts of Flamenco had a Command consist of "name + settings", and
other parts used "type + parameters" (with the same semantics). This is
now unified to "name + parameters".
