Recently I upgraded to version 2.8.0 of git on cygwin. I’m running under Windows 2008 R2. Before this upgrade we were able to share a NFS drive as a main repository. After the upgrade the permissions were changed so that only a single person had write access to the repository on a shared NFS drive. When the push is done to the NFS drive these permissions cause deny write access to the other users of the repository so we couldn’t update the sha1 of the head reference. An example of the incorrect permissions are: Allow User Special not inherited This folder only Allow dev Special not inherited This folder only Allow Everyone Read & execute not inherited This folder, subfolders and Allow Administators for machine Special not inherited This folder only Allow SYSTEM Special not inherited This folder only Allow Users for machine Special not inherited This folder only Allow CREATOR OWNER Special not inherited Subfolders and files only Allow CREATOR GROUP Special not inherited Subfolders and files only But the Windows permissions should have been inherited only. Also not the group dev is not in the list. The permissions after a push showed dev on the shared NFS drive along with errors that the permissions were out of order. Allow Administators Full Control D:\ This folder, subfolders and Allow SYSTEM Full Control D:\ This folder, subfolders and Allow User Special D:\ This folder only Allow CREATOR OWNER Special D:\ Subfolders and files only Allow User on Machine Read & execute D:\ This folder, subfolders and Allow User on Machine Special D:\ This folder, subfolders After searching through new groups and the web it was decided to add noacl to the fstab for the cygwin mount: none /cygdrive cygdrive binary,posix=0,user,noacl 0 0 Now we are finding that the git merge onto our local drive after a fetch from the NFS shared repository is taking a very long time.

If noacl is causing this very large delay (which I suspect to be the case since we didn’t have this large delay till the noacl was added) is there another way to fix the permission issue when using an NFS drive as a shared repository? -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
