Enable upload from network folder

Is your feature request related to a problem? Please describe.
ARC stored and edited on an network drive. When trying to commit / upload error occurs:

git checkout tal: detected dubious ownership in repository at '//syno.bio.uni-kl.de/biotech/ARCsyncETC/test/testarc/testarc'
fatal: detected dubious ownership in repository at '//syno.bio.uni-kl.de/biotech/ARCsyncETC/test/testarc/testarc'
'//syno.bio.uni-kl.de/biotech/ARCsyncETC/test/testarc/testarc' is owned by:
'S-1-5-21-1036228674-4065426080-1347446729-74989'
but the current user is:
'S-1-5-21-1788749962-3905053420-4232863692-500'
To add an exception for this directory, call:
git config --global --add safe.directory '%(prefix)///syno.bio.uni-kl.de/biotech/ARCsyncETC/test/testarc/testarc'

Describe the solution you'd like
be able to commit and push data from networkdrive, give it the option to be a save directory (last line in error message)

Describe alternatives you've considered
same happened as well with ARCcommander, after starting sync error occured, then i executed the git command (the folder added to save directory) and everything worked fine

Could theoretically be fixed with adding safe directory to gitconfig

This is something that needs to be handled outside ARCitect. A git repository on a network drive introduces ambiguities regarding credentials.

A git repository on a network drive introduces ambiguities regarding credentials.

True, but how to properly handle that outside of ARCitect?
The design decision was made to ship the git binary; so users without git installed won't be able to adapt that config.

[JonasLukasczyk]

I will close this for now because multiple people editing the same repo in a shared file system goes a bit against the intended use of git (in which every user has a local copy). If this is still relevant feel free to reopen the issue and we will find a fix.

[Brilator]

Agree that multiple people should collaborate via git / gitlab logic (not on same location on a server).
But that's not the issue here. Users don't want to share there large files (ARCs) on personal computers, but rather store them directly on a shared NAS (also for additional backups, etc.).

Same issue here. We have about 100 images of 50 GB each currently on a fileserver, that we must upload to the cloud. Copying the images locally first is not an option.

In the meantime, I can try the git config --global --add safe.directory workaround.

This flag is now set by default 93c5cef. Please note that using git on a shared storage can leak git credentials.
