Subject: [PU PATCH] Fix git fetch for very large ref counts
Date: Tue, 13 Feb 2007 01:21:38 +0000	[thread overview]
Message-ID: <11713297014015-git-send-email-julian@quantumfyre.co.uk> (raw)

The updated git fetch in pu is vastly improved on repositories with very
large numbers of refs.  The time taken for a no-op fetch over ~9000 refs
drops from ~48m to ~0.5m.

However, before git fetch will actually run on a repository with ~9000
refs the calling interface between fetch and fetch--tool needs to be
changed.  The existing version passes the entire reflist on the command
line, which means that it is subject to the maxiumum environment size
passed to a child process by execve.

The following patches add a stdin based interface to fetch--tool allowing
the ~9000 refs to be passed without exceeding the environment limit.
