1809043 - Close RemoteQuotaObjectParent during access handle closing in the parent process

Status: RESOLVED FIXED

(Core :: DOM: File, task, P2)

Description

[Jan Varga [:janv]]

After bug 1809035, RemoteQuotaObjectParent objects will be closed in FileSystemManagerParent::ActorDestroy. We plan to verify the file in RemoteQuotaObjectParent::ActorDestroy and potentially change the size of the file. If we keep closing RemoteQuotaObjectParent objects in FileSystemManagerParent::ActorDestroy then we might record wrong size of the file in the database (for quota management purposes) because the new file size is updated in FileSystemDataManager::UnlockExclusive which is called from FileSystemAccessHandleParent::Close and the top level actor is always destroyed after actors for subprotocols. So RemoteQuotaObjectParent objects need to be closed during access handle closing in the parent process.

The destructor still has to run on the owning thread.

Parent objects are usually actors as well, but the access handle is special
because it will need to have multiple actors.

Asynchronous closing can't be triggered from the destructor because it needs to
add a strong ref to self.

FileSystemAccessHandle::Create now returns a MozPromise, but the creation does
nothing on other threads for now.

Active FileSystemAccessHandles will prevent FileSystemDataManager from closing.
