#47918 [Com]: stream_set_blocking() does not work with pipes opened with proc_open()

ID: 47918 Comment by: morrisdavidd at gmail dot com Reported By: RQuadling at GMail dot com Status: Open Bug Type: Streams related Operating System: Windows PHP Version: 5.*, 6CVS (2009-06-19 New Comment: I tested this on PHP 5.3 (on Linux) and duplicated the error that the print_r command shows blocking as true. HOWEVER, the stream does not block when actually tested... a simple test script can be created by adding a line and slightly modifying the scripts found at: http://bugs.php.net/bug.php?id=49084 Previous Comments: ------------------------------------------------------------------------ [2009-06-19 11:12:34] jani@php.net If it exists below 5.3, the version must state it! Do NOT touch it again. ------------------------------------------------------------------------ [2009-06-19 09:31:34] RQuadling at GMail dot com Only worry about 5.3+ ------------------------------------------------------------------------ [2009-05-08 09:58:57] RQuadling at GMail dot com I also tried opening the pipes descriptors like ... $a_Descriptors = array(0 => array('pipe', 'rn'), 1 => array('pipe', 'wn'), 2 => array('pipe', 'wn')); but no change. ------------------------------------------------------------------------ [2009-04-07 21:50:45] RQuadling at GMail dot com I tried both 0 and False to set non blocking mode. In all cases the function returns false and the meta data reports that the pipe is still in blocking mode. I've just tried it with PHP 5.2.8 (cli) (built: Dec 8 2008 19:31:23) (on Windows XP SP3) on my home laptop and the same problem. ------------------------------------------------------------------------ [2009-04-07 12:31:33] RQuadling at GMail dot com Description: ------------ I'm trying to set non-blocking mode on pipes attached to a process opened using proc_open. The documentation and the user notes suggest that what I am doing should work. Running this with php -n to remove my ini file settings. Reproduce code: --------------- <?php echo PHP_VERSION, ' ', PHP_OS, ' ', PHP_SAPI, PHP_EOL; echo 'INI:', php_ini_loaded_file(), PHP_EOL; // Define the descriptors. $a_Descriptors = array(0 => array('pipe', 'r'), 1 => array('pipe', 'w'), 2 => array('pipe', 'w')); // Provide a place for the pipes. $a_Pipes = array(); // Create the thread. $r_Thread = proc_open("dir c:\\ /b", $a_Descriptors, $a_Pipes, Null, $_ENV); // Display the current STDOUT meta data. print_r(stream_get_meta_data($a_Pipes[1])); // Try to change the blocking mode to non-blocking. echo (stream_set_blocking($a_Pipes[1], False) ? 'Successfully' : 'Failed'), ' to set blocking mode to non-blocking', PHP_EOL; // Display the current STDOUT meta data. print_r(stream_get_meta_data($a_Pipes[1])); Expected result: ---------------- 5.3.0RC2-dev WINNT cli INI: Array ( [stream_type] => STDIO [mode] => r [unread_bytes] => 0 [seekable] => [timed_out] => [blocked] => 1 [eof] => ) Successfully set blocking mode to non-blocking Array ( [stream_type] => STDIO [mode] => r [unread_bytes] => 0 [seekable] => [timed_out] => [blocked] => [eof] => ) Actual result: -------------- 5.3.0RC2-dev WINNT cli INI: Array ( [stream_type] => STDIO [mode] => r [unread_bytes] => 0 [seekable] => [timed_out] => [blocked] => 1 [eof] => ) Failed to set blocking mode to non-blocking Array ( [stream_type] => STDIO [mode] => r [unread_bytes] => 0 [seekable] => [timed_out] => [blocked] => 1 [eof] => ) ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=47918&edit=1
