Revision fc4c4cd21c783b6dc387002c6e018d26f7405e9f authored by Junio C Hamano on 04 April 2006, 21:52:53 UTC, committed by Junio C Hamano on 04 April 2006, 21:52:53 UTC
Bunch of cleanups with a few notable enhancements since 1.3.0-rc1: - revision traversal infrastructure is updated so that existence of paths limiters and/or --max-age does not cause it to call limit_list(). This helps the latency working with the command quite a bit. - comes with updated gitk. One notable fix is to make sure that the IO is restarted upon signal even on platforms whose default signal semantics is not to do so. This is the fix for the notorious "clone is broken since 1.2.2 on Solaris" problem. Signed-off-by: Junio C Hamano <junkio@cox.net>
