Unable to delete .pack file from submodule git folder [message #1848405] Wed, 01 December 2021 11:20 Go to next message

Hello,

I have an Eclipse RCP application that uses JGit to implement a feature of adding and removing submodules in a project.

I have a problem while deleting any submodule after committing it to a repo as there is a .pack file locked by JGit and couldn't be removed until closing Eclipse itself.

These are the steps:
1- Adding any submodule to the project using JGit
2- Then committing it to repo.
3- Restart Eclipse.
4- Try to delete the submodule (submodule path + submodule .git path )

Here the problem happens, the file "objects\pack\pack-39b5080848e019a9377ff2a8c1ab4853b76ba739.pack" for example couldn't be deleted.

Note:
- The problem happens when restarting Eclipse after addition.
- All Git objects are closed as we restarted Eclipse and no Git operation done on the start.

Can you please help?

EGIT 5.12
Windows 10

Thanks
Hossam

SubmoduleAddCommand#call returns the submodule repository. Did you close that ?

Check if its Repository.useCnt is 0 when you expect it to be closed.

RepositoryCache doesn't immediately release cached repositories. You can try to use its close method to explicitly remove a repository from the cache.

Every repository is closed as it's after Eclipse restart directly and I didn't perform any git operation.
I also tested RepositoryCache#close but still the same problem exist.

I noticed something but I don't the impact of it.
The project which I'm using my plugin in, is loaded in the Project explorer and also in the window "Git Repositories" which means "EGit" uses it and may be it's the cause of locking the file after restarting Eclipse.
could you confirm that or not?
And if it locks the submodule and prevent it form removal, what is the solution?

By default EGit auto-shares git repositories it finds.
You can disable that under "Preferences > Version Control > Git > Projects > Automatically share projects located in a git repository"

How exactly are you trying to delete the file? Note that Java cannot delete read-only files on Windows; you have to set them writeable first.

Great, I tried this and it didn't include my project in "Git repository" view when importing the project.
So the files didn't locked by Egit and I could remove them without any problem.

Thank you Matthias ,
