controlling cvs from php

Hello, I'm trying to login to a cvs repository and upload/download files from a php script utilizing the 'cvs' command. I'm trying to avoid the use of external libraries, etc... Is it possible to do this with popen, or more likely with proc_open? I'd prefer to do it with the former so as to not require PHP 4.3+, but in my testing I've been unable to do it with either command. I've looked through the examples of using proc_open at php.net, but have been unable to translate these into a script that simply logs into cvs. The return code from proc_close is always 1, and the best I've gotten is an error saying "used empty password; try 'cvs login' with a real password". Any pointers into how I can make this work would be greatly appreciated!! Here's roughly what I'm trying to do: ---------- $dspec = array( 0 => array("pipe", "r"), // standard in 1 => array("pipe", "w"), // standard out ); $proc = proc_open("/usr/local/bin/cvs -d pserver:@my.server:/home/cvs login 2>&1", $dspec, $pipes); if(is_resource($proc)) { $output .= fgets($pipes[1], 1024); $output .= fgets($pipes[1], 14); fclose($pipes[1]); if (!fwrite($pipes[0], "cvspassword")) { echo "Error..."; exit; } fclose($pipes[0]); echo proc_close($proc); $output .= "command returned $return_value\n"; } ---------- Thanks, -Jeremy -- Jeremy Andrews <mailto:jeremy@kerneltrap.org> PGP Key ID: 8F8B617A http://www.kerneltrap.org/
