Yes, AI scraper bots again :{
See https://inbox.sourceware.org/[email protected]
and notices posted at https://fosstodon.org/@sourceware
We switched off the "smart protocol" for http(s) and enabled the "dumb
protocol". The dumb git protocol works, but is somewhat inefficient and
for really big repos like gcc.git requires thousands of fetches (and
if you start fresh any failure like you reported will result in you
having to start from scratch again).
The git:// or ssh:// protocols still use the smart protocol and so
should be more realiable.
The mirrors on https://forge.sourceware.org/gcc/gcc-mirror and
https://git.sr.ht/~sourceware/gcc are up to date and could also be used.
It seems to bots have lost interest so maybe we can reduce the anubis
paranoia and re-enable the smart protocol again. I'll try, but if the
bots return we might have to disable it again, so using different
protocol or a mirror if you have to use https might be a good idea for
now.
Cheers,
Mark
