PHP 4.0 Bug #6104 Updated: popen returns -1

ID: 6104 Updated by: jmoore Reported By: Alan@Halachmi.net Status: Closed Bug Type: *General Issues Assigned To: Comments: Sounds like an incorrect popen call to me (Its returning false not -1) try this instead: $mail = popen($default->path_to_sendmail." -i -f$from -- $recipients", 'w'); This should fix this. If it doesnt please reopen with a smaller reproducing script and full system info. Also try the latest CVS to see if that fixes it. Previous Comments: --------------------------------------------------------------------------- [2000-08-11 06:23:11] Alan@Halachmi.net This code snippit from horde.lib (www.horde.org): // Finally, send the mail. if (@is_executable($default->path_to_sendmail)) { $mail = popen("$default->path_to_sendmail -i -f$from -- $recipients", 'w'); $result = fputs($mail, $bhdrs . $hdrs); echo "1: " . $result; $result += fputs($mail, "n"); // trailing n to end the headers section echo "2: " . $result; $result += fputs($mail, $body); echo "3: " . $result; if (pclose($mail) != 0) $result = 0; echo "4: " . $result; } else { if (empty($envelope['To'])) $envelope['To'] = ''; if (empty($envelope['Subject'])) $envelope['Subject'] = ''; if (mail($envelope['To'], $envelope['Subject'], $body, $hdrs . $mhdrs)) $result = 1; else $result = 0; } Yields the following output: 1: 345 2: 346 3: 354 4: 0 The return value of pclose() is not the exit status of the program, but a value as returned by waitpid() of wait4(). I've run what the popen command-line calls by hand using truss, and sendmail is returning exit(0). So, I dug a bit further... pclose($mail) is returning -1. Any ideas on how I can track down why? This function is not reported to be misbehaving on other platforms. --------------------------------------------------------------------------- Full Bug description available at: http://bugs.php.net/?id=6104
