When a task bucket is updated without changing buckets (early return in
updateTaskBucket), b.Task remains nil. The TaskUpdatedEvent was then
dispatched with a nil Task, causing a nil pointer dereference in
HandleTaskUpdatedMentions when accessing event.Task.Description.
This adds:
- A nil guard in TaskBucket.Update to skip event dispatch when b.Task is nil
- Nil checks in HandleTaskUpdatedMentions, HandleTaskCreateMentions,
HandleTaskCommentEditMentions, and UpdateTaskInSavedFilterViews
- Tests verifying the handlers gracefully handle nil task events
Closes#2351
BREAKING CHANGE: The bucket id of the task model is now only used internally and will not trigger a change in buckets when updating the task.
This resolves a problem where the task update routine needs to know the view context it is in. Because that's not really what it should be used for, the extra endpoint takes all required parameters and handles the complexity of actually updating the bucket.
This fixes a bug where it was impossible to move a task around between buckets of a saved filter view. In that case, the view of the bucket and the project the task was in would be different, hence the update failed.
