Subject: [PATCH 1/6] Add a testcase for ACL with restrictive umask.
Date: Mon, 22 Feb 2010 23:32:11 +0100 [thread overview]
Message-ID: <1266877936-13537-2-git-send-email-Matthieu.Moy@imag.fr> (raw)
In-Reply-To: <1266597207-32036-1-git-send-email-Matthieu.Moy@imag.fr>
Right now, Git creates unreadable pack files on non-shared
repositories when the user has a umask of 077, even when the default
ACLs for the directory would give read/write access to a specific
user.
Loose object files are created world-readable, which doesn't break ACLs,
but isn't necessarily desirable.
