  • Lock/unlock a file when opening/closing
  • Open files in read only mode when locked
  • Indicate other lock in the UI
  • Safeguard unlocking through the cleanup cronjob if no close request was sent
  • Changing ETag on lock/unlock causes a conflict, so we either need a way to still propagate the change to the root without changing the actual file tag for shares as mentioned in Collaborative locking files_lock#54 or adjust the change detection in text to maybe also compare the mtime in addition

To be tested together with nextcloud/files_lock#54

LGTM. A few minor remarks.

$this->lockManager->lock(new LockContext(
$file,

Out of topic but this could become Application::APP_ID at some point.

I'd let the actual lock provider handle that, from the text app side there is no special interest if we unlock a file that has already been unlocked.
