Not bogus.... see below: Its obviously not returning properly: 1. while (($pid=pcntl_waitpid(-1,$status,WNOHANG))>0) { 2. echo "RAW: {$status}\n"; 3. var_dump(pcntl_wifexited($status)); 4. var_dump(pcntl_wexitstatus($status)); 5. var_dump(pcntl_wifsignaled($status)); 6. var_dump(pcntl_wtermsig($status)); 7. var_dump(pcntl_wifstopped($status)); 8. var_dump(pcntl_wstopsig($status)); 9. echo "END RAW: {$status}\n"; 10. } 11. 12. RAW: 65280 13. pcntl_wifexited == bool(true) => pcntl_wexitstatus == int(-1) 14. pcntl_wifsignaled == bool(false) => pcntl_wtermsig == int(0) 15. pcntl_wifstopped == bool(false) => pcntl_wstopsig == int(255) 16. END RAW: 65280 17. 18. 19. RAW: 65280 20. bool(true) 21. int(-1) 22. bool(false) 23. int(0) 24. bool(false) 25. int(255) 26. END RAW: 65280 Guess ill be hax0ring the code to make it work properly. seems the same on PHP 5.3.0-RC2 Previous Comments: ------------------------------------------------------------------------ [2009-03-05 20:54:53] james at jamesreno dot com exit(254); $pid = pcntl_waitpid(-1,$status); if (pcntl_wifexited($status)) { $status = pcntl_wexitstatus($status); echo $status; } Then why is $status, -2 rather than '254'? This method does not seem work *properly* either... ------------------------------------------------------------------------ [2009-03-04 23:11:46] fel...@php.net You need to use the pcntl_wexitstatus(). http://docs.php.net/manual/en/function.pcntl-wexitstatus.php http://www.mkssoftware.com/docs/man3/waitpid.3.asp ------------------------------------------------------------------------ [2009-03-04 21:59:01] james at jamesreno dot com Description: ------------ The $status exitcode returned by pcntl_waitpid() is incorrectly casted resulting in an invalid number being returned. I believe the int is converted to a long in ext/pcntl/pcntl.c, resulting in an invalid integer being returned to the parent. zval *z_status = NULL; int status; convert_to_long_ex(&z_status); status = Z_LVAL_P(z_status); child_id = waitpid((pid_t) pid, &status, options); Z_LVAL_P(z_status) = status; z_status is a long, but status is an int... Reproduce code: --------------- <? $pid = pcntl_fork(); if ($pid == -1) { echo "Unable to fork"; exit; } elseif ($pid) { $epid = pcntl_waitpid(-1,$status); echo "PARENT: {$pid}/{$epid} exited {$status}\n"; exit(128); } else { echo "CHILD: Exiting with exit code 128\n"; exit(128); } ?> Expected result: ---------------- [ja...@localhost ~]$ php test.php CHILD: Exiting with exit code 128 PARENT: 7598/7598 exited 128 [ja...@localhost ~]$ echo $? 128 [ja...@localhost ~]$ Actual result: -------------- [ja...@localhost ~]$ php test.php CHILD: Exiting with exit code 128 PARENT: 7598/7598 exited 32768 [ja...@localhost ~]$ echo $? 128 [ja...@localhost ~]$ ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=47566&edit=1
