Category: None Group: None Status: Open Resolution: None Priority: 5 Private: No Submitted By: Nobody/Anonymous (nobody) Assigned to: Nobody/Anonymous (nobody) Summary: libssh2_poll detects data on channel, but no data available Initial Comment: I've got a small home-brewed SSH client and I've encountered a problem in the library with libssh2_poll() when checking for data on a channel. Simply put, here's the setup. I have a thread that polls for data on a channel every few usec. When the libssh2_poll function detects data available to be read on the channel I'm interested in, I immediately try to read from that channel. Trouble is, if its a small piece of data that I'm expecting, the read fails while subsequent polls still think that there is data there. So In my SSH client with a pty, I do something like hit the "z" key. This should send a single character over the lines to the remote SSH server plus any SSH/TCP/IP.... overhead. Now the remote SSH server will echo back the key plus any additional terminal formatting. As soon as I hit my "z" key, libssh2_poll alerts me that data is available to be read from the channel, but attempting to read from the channel doesn't read any data...polling keeps saying theres data, I read nothing... repeat a lot of times... If I keep hitting keystrokes, eventually the channel read picks up the data. So it seems like libssh2 holds onto small packets for some reason. ---------------------------------------------------------------------- Comment By: Paul Thomas (thomaspu) Date: 2008-10-01 21:12 Message: This one was written up by me, I just forgot to log in again! ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=703942&aid=2141548&group_id=125852 ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ libssh2-devel mailing list libssh2-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/libssh2-devel
