Public bug reported:
On an NFSv4 mounted directory with ACLs turned on, git refuses to clone a
repository.
Cloning on local file systems works perfectly.
To reproduce the error use a NFSv4 mounted directory with enforced ACLs turned
on (for example as provided by a NetApp Fileserver) and try to clone an
existing repository, e.g.:
>> git clone git://gitorious.org/verisim/verisim.git
This will produce:
>> Cloning into verisim...
>> remote: Counting objects: 251, done.
>> remote: Compressing objects: 100% (247/247), done.
>> remote: Total 251 (delta 142), reused 0 (delta 0)
>> Receiving objects: 100% (251/251), 52.03 KiB, done.
>> error: inflate: data stream error (unknown compression method)
>> fatal: serious inflate inconsistency
>> fatal: index-pack failed
A strace or cloning to a local file system and copying the cloned repository to
the NFS directory reveals the following:
It seems that git creates some readonly files and tries to write content into
them.
(In the above example, e.g.
verisim/.git/objects/pack/pack-4878e1ecd5a389fffd61b6b12b51ee61a8d19f39.idx)
As this violates access rights (you are not able to write to a readonly file if
ACLs are correctly enforced) cloning the repository fails.
