#37367 [Opn]: WNOHANG option causes no PID to be returned.

[2006-05-08 16:55:22] doprea at chimesnet dot com Description: Thanks in advance for helping me to resolve this issue-- It will be a great help!! Passing the WNOHANG option will cause pcntl_wait() and pcntl_waitpid() to never return a PID, but only 0 or -1 (0 before a child returns, and -1 after). I have tested this under version 5.0.4-10, 5.1.2-5, and 5.1.4, both with and without the --enable-sigchild build option. Reproduce code: --- ftp://www.redplanet5.net, user= [EMAIL PROTECTED], pass= temp. Expected result: It will fork a child from the parent, and then a second child from the first. If you send a TERM from the shell to the first child, it will attempt to end the second child, and report whether or not it received an acceptable wait() response. Just remove the WNOHANG flag and it works flawlessly. As written, the WNOHANG option was passed to the pcntl_wait() function, and the program will report that there may have been a problem with the termination of the child. Actual result: -- If the WNOHANG option is removed, the program says that the child exited nicely. This should be the case regardless of whether or not the WNOHANG option was passed. -- Edit this bug report at http://bugs.php.net/?id=37367edit=1
