1 My understanding of a lockfile seems to be different from your's so i'd come up with something like:
2
3
4 FETCHPROG=proz
5 FETCHCOMMAND="(
6 while [ -e \${DISTDIR}/`basename \${URI}`.lock ]; do
7 sleep 5; done &&
8 if [ ! -e \${DISTDIR}/`basename \${URI}` ]; then
9 touch \${DISTDIR}/`basename \${URI}`.lock;
10 \$FETCHPROG \${URI};
11 rm \${DISTDIR}/`basename \${URI}`.lock;
12 fi
13 )"
14
15 in this case error handling remains on the FETCHPROG side.
