Description H.J. Lu 2021-10-12 14:05:30 UTC

I am behind a firewall and using gitproxy:

exec socat - socks4:proxy-server-name:$1:$2

I got

$ git clone git://gcc.gnu.org/git/gcc.git 
Cloning into 'gcc'...
fetch-pack: unexpected disconnect while reading sideband packet
fatal: early EOF
fatal: fetch-pack: invalid index-pack output
$

Both

$ git clone --depth 1 git://gcc.gnu.org/git/gcc.git

and

$ git clone https://gcc.gnu.org/git/gcc.git

work.

I have no problem on Fedora 34.

This is almost surely going to have to end up on the git list... but you might try to use:

    git -c protocol.version=1 clone git://gcc.gnu.org/git/gcc.git

to see if that has an effect.

The release notes mention a fix to fetching which affects the v2 protocol:

    https://github.com/git/git/commit/ae1a7eefff

Either way, I would suggest bringing this up on the git list as that's where the folks most likely to know the problem will be found.

Comment 2 H.J. Lu 2021-10-12 19:59:18 UTC

$ git -c protocol.version=1 clone git://gcc.gnu.org/git/gcc.git

works.

Comment 3 H.J. Lu 2021-10-12 20:00:45 UTC

git 2.33.0 fails and git 2.32.0 works.

Comment 4 H.J. Lu 2021-10-12 21:42:12 UTC

"socat -t 10" also works.
