From 57e58c3aa7a2477ce7fa56bfea9d927b4eb43ccd Mon Sep 17 00:00:00 2001 From: Peter Wemm Date: Mon, 26 Jan 1998 03:09:57 +0000 Subject: Import cvs-1.9.23 as at 19980123. There are a number of really nice things fixed in here, including the '-ko' vs. -A problem with remote cvs which caused all files with -ko to be resent each time (which is damn painful over a modem, I can tell you). It also found a heap of stray empty directories that should have been pruned with the -P flag to cvs update but were not for some reason. It also has the fully integrated rcs and diff, so no more fork/exec overheads for rcs,ci,patch,diff,etc. This means that it parses the control data in the rcs files only once rather than twice or more. If the 'cvs diff' vs. Index thing is going to be fixed for future patch compatability, this is the place to do it. --- contrib/cvs/diff/cmpbuf.c | 40 ++++++++++++++++++++++++++++++++++++++++ 1 file changed, 40 insertions(+) create mode 100644 contrib/cvs/diff/cmpbuf.c (limited to 'contrib/cvs/diff/cmpbuf.c') diff --git a/contrib/cvs/diff/cmpbuf.c b/contrib/cvs/diff/cmpbuf.c new file mode 100644 index 000000000000..e95a8f98ed9d --- /dev/null +++ b/contrib/cvs/diff/cmpbuf.c @@ -0,0 +1,40 @@ +/* Buffer primitives for comparison operations. + Copyright (C) 1993 Free Software Foundation, Inc. + + This program is free software; you can redistribute it and/or modify + it under the terms of the GNU General Public License as published by + the Free Software Foundation; either version 2, or (at your option) + any later version. + + This program is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
