ID: 34972 Comment by: donnyk at gmail dot com Reported By: VJTD3 at VJTD3 dot com Status: Open Bug Type: Streams related Operating System: * PHP Version: php5.1-200603270630 Assigned To: wez New Comment:
i also have the same problem, i've tried the latest snapshot on windows to no avail. It works on my linux systems however. Previous Comments: ------------------------------------------------------------------------ [2007-08-10 13:01:48] VJTD3 at VJTD3 dot com <?php stream_set_blocking(STDIN, FALSE); echo fread(STDIN, 10); ?> notice how it just sits there? (blocking) it should exit instantly with a null echo. (same as a tcp connection where if you just do a read that is too fast with nonblocking it never gets a chance to fetch the data.) what is happening is that php is blocking waiting for input (specifically enter (line ending)) problem: if you are echoing debug information and want to use key functionality in tandem you can't because everything is blocked till you hit enter. ------------------------------------------------------------------------ [2007-07-25 01:00:00] php-bugs at lists dot php dot net No feedback was provided for this bug for over a week, so it is being suspended automatically. If you are able to provide the information that was originally requested, please do so and change the status of the bug back to "Open". ------------------------------------------------------------------------ [2007-07-17 14:28:03] [EMAIL PROTECTED] Please try using this CVS snapshot: http://snaps.php.net/php5.2-latest.tar.gz For Windows (zip): http://snaps.php.net/win32/php5.2-win32-latest.zip For Windows (installer): http://snaps.php.net/win32/php5.2-win32-installer-latest.msi I can't reproduce this (or very likely didn't understand the problem :) ------------------------------------------------------------------------ [2006-03-27 14:12:28] VJTD3 at VJTD3 dot com error in last message, "stream_select()" was ment. code using "stream_select()" that still blocks: <?php set_time_limit('0'); # note for php4 or lower STDIN isn't a defined "constant". if (version_compare(phpversion(), '5.0.0', '<')) { define('STDIN', fopen('php://stdin', 'r')); } for ($i=1;$i<11;$i++) { unset($read); $read[] = STDIN; stream_select($read, $write = null, $except = null, $tv = 0); if (count($read)) { $data4 = @fread(STDIN, 1500); $data4 = str_replace("\r\n", "\n", $data4); $data4 = str_replace("\n\r", "\n", $data4); $data4 = str_replace("\r", "\n", $data4); $data4 = str_replace("\n", '', $data4); } echo 'pass: '.$i.' -> data: '.(strlen(@$data4) ? $data4 : 'empty')."\n"; unset($data4); sleep('1'); } ?> the second you type/click a arrow key/anything it goes into blocking mode again. ------------------------------------------------------------------------ [2006-03-27 13:32:01] VJTD3 at VJTD3 dot com bug #36030 is very similar to my bug, they might be related. It looks like anything to STDIN (reguardless of access method like php://stdin and constant('STDIN') and STDIN are all effected.) When doing anything, be it select, timeout, or anything to "monitor" the resource where a window is set (ie to timeout the blocking, set nonblocking, or similar.) the input "stalls" (it's not really a stall, it's just waiting for the input.) or fails (such as timeout setting that fails and returns false.) Tested on: php4-STABLE-200603270430 php5.1-200603270630 php6.0-200602191730 Also tested as well on their *nix snaps version and all with the same result. (blocking when they should not be blocking.) Better code to make debugging easier and includes examples from suggestions that don't work: <?php set_time_limit('0'); # note for php4 or lower STDIN isn't a defined "constant". if (version_compare(phpversion(), '5.0.0', '<')) { define('STDIN', fopen('php://stdin', 'r')); } echo 'notice how the data loads unblocked reguardless if there is data.'."\n"; $demo1 = @fsockopen('yahoo.com', 80, $errno, $errstr, 60); stream_set_blocking($demo1, FALSE); fwrite($demo1, 'GET /'."\n\n"); for ($i=1;$i<11;$i++) { $data1 = @fread($demo1, 1500); $data1 = str_replace("\r\n", "\n", $data1); $data1 = str_replace("\n\r", "\n", $data1); $data1 = str_replace("\r", "\n", $data1); $data1 = str_replace("\n", '', $data1); echo 'pass: '.$i.' -> data: '.(strlen($data1) ? $data1 : 'empty')."\n"; sleep('1'); } echo 'notice how the data loads unblocked and clearly there is no data because this IP is invalid to connect to.'."\n"; $demo2 = @fsockopen('0.0.0.0', 80, $errno, $errstr, 1); stream_set_blocking($demo2, FALSE); for ($i=1;$i<11;$i++) { # this is expected to be a invalid resource. $data2 = @fread($demo2, 1500); $data2 = str_replace("\r\n", "\n", $data2); $data2 = str_replace("\n\r", "\n", $data2); $data2 = str_replace("\r", "\n", $data2); $data2 = str_replace("\n", '', $data2); echo 'pass: '.$i.' -> data: '.(strlen($data2) ? $data2 : 'empty')."\n"; sleep('1'); } echo 'a person said to use select, this shows select won\'t work. (and shouldn\'t it\'s not a socket.) It won\'t even allow input during select calls.'."\n"; for ($i=1;$i<11;$i++) { unset($read); $read[] = STDIN; socket_select($read, $write = null, $except = null, $tv = 0); print_r($read); sleep('1'); } echo 'same code as yahoo and 0.0.0.0 with fread and blocked reguardless of setting this to nonblocking.'."\n"; stream_set_blocking(STDIN, FALSE); for ($i=1;$i<11;$i++) { echo 'Watch me stall till you type enter I\'m blocking you!'."\n"; $data3 = fread(STDIN, 10); $data3 = str_replace("\r\n", "\n", $data3); $data3 = str_replace("\n\r", "\n", $data3); $data3 = str_replace("\r", "\n", $data3); $data3 = str_replace("\n", '', $data3); echo 'pass: '.$i.' -> data: '.(strlen($data3) ? $data3 : 'empty')."\n"; sleep('1'); } ?> anything I can do to help with details/make the bug easier to fix? ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
