iceberg keeps files open #1394

Open SabineMa opened 3 years ago

SabineMa commented 3 years ago

while looking for this issue: https://github.com/pharo-project/pharo/issues/7960 I detect, that iceberg keeps a lot of files open. This does not make problems currently but I think that this should not be.

@guillep was answering in discord:

I saw it and I agree that it should be fixed
it seems that opening a repository keeps the git metadata files open
that is managed internally by libgit and we don't have too much to do about it
what we could do from an iceberg perspective is to not keep repositories open
instead, we should open them when required and close them after
I cannot estimate what is the effort required to do that, mainly because I smell that the opening of the repositories is triggered by Iceberg's UI (it's done in a lazy fashion, that I'm sure)
thing is also that iceberg is going through a UI migration to Spec 2

Hi! I enabled CI on Windows platform and get errors that I suspect are caused by this issue.

The tests raise "CannotDeleteFileException: Could not delete file File. Check the file is not open.", which happens when tearDown try to clean up test directories but the files are still open. (ref).

For the record, I observed that test cases that raise the error in windows have in common the use of one fixture. This snippet shows it:

"This create one more file open (in MacOS)".
f1 := IceClonedFromRemoteFixture inGit.
f1 setUp.
f1 tearDown.

"No new files here:"
f2 := IceWithRemoteAndLocalCommitAndUpstreamFixture inGit.
f2 setUp.
f2 tearDown.

I did some tries without success, to isolate where is the leak.
