Re: [gentoo-portage-dev] Downloading while compiling - FETCHCOMMAND inside.

[Wiebel2001@t-online.de (Wiebel)]

My understanding of a lockfile seems to be different from your's so i'd come up with something like:


FETCHPROG=proz
FETCHCOMMAND="(
while [ -e \${DISTDIR}/`basename \${URI}`.lock ]; do
sleep 5; done &&
if [ ! -e \${DISTDIR}/`basename \${URI}` ]; then
touch \${DISTDIR}/`basename \${URI}`.lock;
\$FETCHPROG \${URI};
rm \${DISTDIR}/`basename \${URI}`.lock;
fi
)"

in this case error handling remains on the FETCHPROG side.
