Due to an issue (which has been fixed in the previous commit), all tasks
in the database were deleted when starting Flamenco. This tool attempts
to recompile the job and recreate its tasks.
The statuses of the tasks are set based on the job status. Basically:
- job active → tasks queued
- job completed → tasks completed
- job cancelled / failed → tasks cancelled
- otherwise → tasks queued
To ensure that the tool is only used to create tasks from scratch, it
refuses to work on a job that still has tasks in the database.
There is an issue with the GORM auto-migration, in that it doesn't
always disable foreign key constraints when it should. Due to
limitations of SQLite, not all 'alter table' commands you'd want to use
are available. As a workaround, these steps are performed:
1. create a new table with the desired schema,
2. copy the data over,
3. drop the old table,
4. rename the new table to the old name.
Step #3 will wreak havoc with the database when foreign key constraint
checks are active, so no we temporarily deactivate them while performing
database migration.
Mark the default value of `Worker.LazyStatusRequest` as `false`. The
previous default was configured as `0`, which was different enough to
always trigger a database migration of that column. However, since these
values do map to each other, the migration didn't do anything concrete,
and would be triggered again at the next startup.
As it was decided that the name "tags" would be better for the clarity
of the feature, all files and code named "cluster" or "worker cluster"
have been removed and replaced with "tag" and "worker tag". This is only
a name change, no other features were touched.
This addresses part of #104204.

As a note to anyone who already ran a pre-release version of Flamenco
and configured some worker clusters, with the help of an SQLite client
you can migrate the clusters to tags. First build Flamenco Manager and
start it, to create the new database schema. Then run these SQL queries
via an sqlite commandline client:
```sql
insert into worker_tags
(id, created_at, updated_at, uuid, name, description)
select id, created_at, updated_at, uuid, name, description
from worker_clusters;
insert into worker_tag_membership (worker_tag_id, worker_id)
select worker_cluster_id, worker_id from worker_cluster_membership;
```
If the mock tests are run by root user then this specific test of
inaccessible path fails because root can write files to anywhere on the
filesystem. It is not clear that Flamenco Manager test
TestCheckSharedStoragePath is checking inaccessible file locations when
it fails and that it should be run by an unprivileged user.
Fix is to fail the permission test if the tests are run as a root user.
Perform these two SQL calls & check their result:
- `PRAGMA integrity_check`
- `PRAGMA foreign_key_check`:
See https: //www.sqlite.org/pragma.html for more info on these.
This also removes the unused `PeriodicMaintenanceLoop()` function.
Periodic checking while Flamenco Manager is running might be introduced
in a future commit, after the startup-time checks have been shown to not
get in the way.
When there is an error detected at startup, close the database connection.
Before, the connection could be kept open even when an error was returned,
causing the write-ahead log files to be kept around. These are now
properly integrated into the main database file before exiting.
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.
Add extra job to the database before deleting one, to ensure that job
deletion doesn't do anything with other jobs (and their tasks).
No functional changes to Flamenco itself.
Before: `3.3-alpha0-v3.2-76-gdd34d538-dirty`
After : `3.3-alpha0 (v3.2-76-gdd34d538-dirty)`
Also include the new `git` property to always have the Git hash (the part
between parentheses).
Limit which worker statuses are remembered (when they go offline) to
those that we want to restore when they come back online. This is now
set to `awake` and `asleep`. This prevents workers from being told to go
to states that they cannot handle, such as `error` or `starting`.
Fix#99549: When sending Workers offline, remember their previous status
When the status of a worker goes offline, the Manager will now make the status of the worker to be remembered once it goes back online. So when the Worker makes this status change (so for example `X → offline`), Manager should immediately set `StatusRequested = "X" ` once it goes online.

To allow more build-time configuration:
- `Makefile` will now pick up `LDFLAGS` from environment variables, and
- locations of configuration files can now be overridden with linker
options.
These are not used for regular Flamenco builds, but do allow studios to
customize where configuration files are stored.

Various improvements to the logging of the job deletion:
- Reduce the log level of the "removing logs" and "removing job from
database" lines from INFO to DEBUG, so that only one line of INFO is
logged per deleted job
- Show size of the queue and the check interval in the "job deletion
queue is full" log message.
When queueing up jobs to be deleted, log how many deletions remain to be
picked up later. Once a minute the database is checked for such deletion
requests, so the next batch will be scheduled in a minute.
Workers can be soft-deleted, which means that they stay in the database.
As such, foreign key constraints `ON DELETE CASCADE` do not trigger, and
thus their sleep schedule can still be active. This is now detected and
handled gracefully.
The Shaman Checkout ID setter shouldn't update a job's "updated at"
timestamp. Its goal is to fake that the job was submitted with a new
enough Flamenco version, and thus should not touch the timestamps.
This is a command that can be run to retroactively set the Shaman
Checkout ID of jobs, allowing the job deletion to also remove the job's
Shaman checkout directory.
This is highly experimental, and not built by default or shipped with
Flamenco releases. It's only been used once at Blender Animation Studio
to help cleaning up. Run at your own risk. Make backups first.
- Add a little confirmation overlay before deleting a job. This overlay
also shows information about whether the Shaman checkout directory
will be deleted or not.
- Send job updates to the web frontend when jobs are marked for
deletion, and when they are actually deleted.
- Respond to those updates, and handle some corner cases where job info
is missing (because it just got deleted).
This closes T99401.
Show jobs that have been marked for deletion with a red strike-through
line in the jobs table, and show the deletion-request timestamp in the
job details.
Implement the `deleteJob` API endpoint. Calling this endpoint will mark
the job as "deletion requested", after which it's queued for actual
deletion. This makes the API response fast, even when there is a lot of
work to do in the background.
A new background service "job deleter" keeps track of the queue of such
jobs, and performs the actual deletion. It removes:
- Shaman checkout for the job (but see below)
- Manager-local files of the job (task logs, last-rendered images)
- The job itself
The removal is done in the above order, so the job is only removed from the
database if the rest of the removal was succesful.
Shaman checkouts are only removed if the job was submitted with Flamenco
version 3.2. Earlier versions did not record enough information to reliably
do this.
If Shaman is used to submit the job files, store the job's checkout ID
(i.e. the path relative to the checkout root) in the database. This will
make it possible in the future to remove the Shaman checkout along with
the job itself.
Manager had a limit of 10 MB, but the Worker can produce images that are
larger than that (even after down-scaling the image). I've bumped the
limit to 25 MB, which should be enough (it's 2x the bug reporter's file
size).
Add a timeout when fetching a job from the persistence layers.
It's my intention to add more timeouts, so this also introduces some code
to make it easier to test that a context has a deadline set.
Deduplicate API implementation code to fetch a job from the persistence
service.
Almost no functional changes. Checking that the requested job UUID is
actually a valid UUID is now consistently done on all fetches. This is
not a functional change in normal Flamenco operations, where only valid
UUIDs are used anyway.
Run `PRAGMA journal_mode = WAL` and `PRAGMA synchronous = normal` when
connecting to the SQLite database. This enables the write-ahead-log journal
mode, which makes it safe to enable "normal" synchronisation (instead of
the default "full" synchronisation).
The preview video task would attempt to use JPEG preview files when the
"Preview" checkbox is checked, even when this checkbox is not shown in
Blender's UI (when the output format is not EXR). Blender still stores
this property, even when it's unused, and that's what tripped up the job
compiler.
The "Simple Blender Render" job type now first checks whether the previews
are necessary at all, and only then uses them.
