Re: Strange: libssh2_channel_read() returns 0

I just tried CVS with my OS X machines, this seems to fix the problem
for me ONLY if I'm doing sleep(1) before I read. Otherwise there's
risk of the read blocking permanently and I have to kill the
application.

Any reason why this blocks but doesn't eventually return? maybe I just
need to do a different approach. Right now I'm using a call that
reads up to 4096 bytes, calls libssh2_channel_read (in blocking mode)
until it returns 0 bytes. In my test case, I was running a command
that produces 879 bytes. When it locked up, it was on the 2nd call to
read where it would be expected to just return 0 but instead it's
waiting for more data which none will come, or so I assume.

thoughts? Is it better to use the non-blocking method maybe? This
was how we were using it before with 0.13 with some success, but if
it's better I can switch. 1.1 has a lot of improvements so wouldn't
mind.
