Same result, no difference, no "ok" displayed Previous Comments: ------------------------------------------------------------------------ [2009-09-28 06:58:38] j...@php.net Please try using this snapshot: http://snaps.php.net/php5.2-latest.tar.gz For Windows: http://windows.php.net/snapshots/ ------------------------------------------------------------------------ [2009-09-27 22:57:05] compconsultant at yahoo dot com Description: ------------ Using proc_open to open a pipe to a command, and, putting stream_select into a function, hangs upon return from that function. Reproduce code: --------------- <?php function SelectStream($StreamsArray) { $Null = array(); $timeout = NULL; stream_select($StreamsArray, $Null, $Null, $timeout); echo "After select\n"; return FALSE; } $ProcDescriptor = array(1 => array("pipe", "w")); $Resource = proc_open("tail -F /var/log/mail.log", $ProcDescriptor, $Pipes, NULL, NULL, array("binary_pipes" => TRUE)); if ($Resource === FALSE) die("proc_open failed\n"); $ProgResource = $Pipes[1]; /* $ProgResource = popen("tail -F /var/log/mail.log", "r"); if ($ProgResource === FALSE) die("Could not open the PIPE\n"); */ $Streams[] = $ProgResource; $Resource = SelectStream($Streams); echo "ok\n"; ?> Expected result: ---------------- I expect ok to be displayed. If you replace proc_open with popen (uncomment the lines), the same function returns fine (ok displayed). If you remove the stream_select, it also returns fine. Actual result: -------------- The string ok is not displayed, the statement is never reached. After select is displayed. So, it is hanging on the return statement. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=49694&edit=1
