Revision 1.3, Wed Apr 26 21:55:22 2006 UTC (18 years, 1 month ago) by joris
Branch: MAIN
Changes since 1.2: +4 -4 lines
prevent file races by obtaining an fd for the RCS file and
do our operations on that, this is safe and guarantees we
can operate on the file until we close(2) it.
a fix is coming for the remaining races in our diff code.
