Re: [jgit-dev] Invalid Channel 117

Thank you - that helps so much, I appreciate the help - and no the C client throws no error - shocked me too.

it expects to see a sideband channel number. It seems you are sending
some data with an invalid pkt-line length header, causing the client
to get out of sync with the stream, or just sending an invalid
sideband.

I am surprised this also doesn't happen with the C client.
recv_sideband() also fails when it sees a channel such as 117 in the
stream.

We don't see this from any other system using JGit, but its possible
something Assembla's server has done has caused the JGit
SideBandInputStream to become unsynchronized from the stream and fail.
A stack trace from the JGit client would help understand better where
this is, but I assume its in the status-report parsing on the client
side. You may want to start hunting for the bug by modifying the
client to print more bytes from the stream when it throws the
exception and see if you recognize any of the data.
