From: bh at ez dot no Operating system: Debian Linux, Unstable PHP version: 5.1.4 PHP Bug Type: PCNTL related Bug description: Signal handling simply does not work!
Description: ------------ PHP5-CLI: "pcntl_signal" is malfunctioning. It traps the desidred signal(s) but it does not execute the code which is in the custom signal handler! This is very annoying. Reproduce code: --------------- <?php function whatever( $signal ) { echo( "Inside whatever, got $signal\n" ); } pcntl_signal( SIGTERM, 'whatever' ); pcntl_signal( SIGUSR1, 'whatever' ); echo( 'My PID is: ' . getmypid() . "\n" ); // Hard-sleep for 30 secs. time_sleep_until( microtime( true ) + 30 ); echo( "Bye.\n" ); ?> Expected result: ---------------- Start up the provided source code using PHP5-CLI, remember the PID that the script outputs and use "kill -15 <PID>" to send a SIGTERM to it. The script should trap the signal, execute the custom signal handler code and thus output: "Inside whatever, got 15" However, this does not happen. Note that the signal is in fact CAUGHT, because if you remove the handler for SIGTERM and then send a signal 15 to the script, it will self-terminate. Apparently none of the other signals work either (checked with SIGUSR1/2, etc.). -- Edit bug report at http://bugs.php.net/?id=38480&edit=1 -- Try a CVS snapshot (PHP 4.4): http://bugs.php.net/fix.php?id=38480&r=trysnapshot44 Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=38480&r=trysnapshot52 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=38480&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=38480&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=38480&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=38480&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=38480&r=needscript Try newer version: http://bugs.php.net/fix.php?id=38480&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=38480&r=support Expected behavior: http://bugs.php.net/fix.php?id=38480&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=38480&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=38480&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=38480&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=38480&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=38480&r=dst IIS Stability: http://bugs.php.net/fix.php?id=38480&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=38480&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=38480&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=38480&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=38480&r=mysqlcfg
