Subject: [PATCH] supply '-n' to gzip to produce identical tarballs
Date: Sun, 10 Apr 2011 16:12:16 +1000	[thread overview]
Message-ID: <1302415936-7362-1-git-send-email-frase@frase.id.au> (raw)

Without the '-n' ('--no-name') argument, gzip includes timestamp in
output which results in different files.  Important systems like FreeBSD
ports and perhaps many others hash/checksum downloaded files to ensure
integrity.  For projects that do not release official archives, gitweb's
snapshot feature would be an excellent stand-in but for the fact that the
files it produces are not identical.

Supply '-n' to gzip to exclude timestamp from output and produce idential
output every time.
