Hi,
I am extremely sorry for the mess because of digest.
I receive the mails in digest and replied to it.(I hope current reply is in
correct format).
I am using libssh2 1.2.4 version on RHEL 5.3 platform and recently using
1.2.7/8 to verify.
I have been able to solve the issue. It was mistake in my code which didn't
handle partial writes(in case of window adjust)
If libssh2_channel_write wrote only partial of what was asked, I was looping
the same buffer as the previous instead of incrementing pointer by the size of
written bytes.
However as previously asked,I would like to understand following excerpt from
scp_write_nonblock.c
rc = libssh2_channel_write(channel, ptr, nread);
if(rc > nread) {
fprintf(stderr, "MOO %d > %d\n", (int)rc, (int)nread);
}
In what scenarios rc would be greater than nread, is it error condition(MOO??),
if yes how to handle it.
While I understand your point about the ssh flow diagram not being absolute
must for client developers, but it would certainly improve the
understanding/knowledge while writing application and to participate in libssh2
development as well. So if anyone has such information please share it.
Thanks a lot for your patience and support.

The detail I said about NOT using the mailing list in digest mode when trying
to have a conversation was not a joke. We cannot have this discussion if you're
going to totally destroy both threading and quoting in every mail you send here.
Also, I did ask you questions about version and platform that I consider vital
for this issue.

A hang would indicate a bug somewhere.
