Revision 4dab94d52e25b6a53a715613ec5b06b42b240106 authored by Junio C Hamano on 20 October 2005, 01:28:17 UTC, committed by Junio C Hamano on 20 October 2005, 04:04:53 UTC
The previous round to optimize fetch-pack has a small bug that feeds SHA1^ ("parent commit") before making sure SHA1 is actually a commit (or a tag that eventually dereferences to a commit). Also it did not help culling the known-to-be-common parents if the common one was a merge. Signed-off-by: Junio C Hamano <junkio@cox.net>

/*
* I'm tired of doing "vsnprintf()" etc just to open a
* file, so here's a "return static buffer with printf"
* interface for paths.
*
* It's obviously not thread-safe. Sue me. But it's quite
* useful for doing things like
*
* f = open(mkpath("%s/%s.git", base, name), O_RDONLY);
*
* which is what it's designed for.
