Subject: [PATCH 3/6] git_mkstemp_mode, xmkstemp_mode: variants of gitmkstemps with mode argument.
Date: Sat, 20 Feb 2010 00:21:55 +0100	[thread overview]
Message-ID: <1266621718-4879-3-git-send-email-Matthieu.Moy@imag.fr> (raw)
In-Reply-To: <vpq7hq8stjt.fsf@bauges.imag.fr>

gitmkstemps emulates the behavior of mkstemps, which is usually used
to create files in a shared directory like /tmp/, hence, it creates
files with permission 0600. But we use it also to create pack files,
which do not need this protection.
