Bug #66830 [NEW]: Empty header causes PHP built-in web server to hang

From: jon dot dufresne at gmail dot com Operating system: Fedora 20 PHP version: 5.5.9 Package: Built-in web server Bug Type: Bug Bug description:Empty header causes PHP built-in web server to hang Description: ------------ Serving the test script below through the PHP built-in web server causes the server to hang. A response is never generated. This script works through mod_php. Once the server hangs, Ctrl-C is insufficient to quit. I am only able to quit using the kill command. Test script: --------------- <?php header(' ', false, 200); Expected result: ---------------- The web server should serve a response with a 200 status code. Actual result: -------------- Web server hangs. Requires killing with the kill command. -- Edit bug report at https://bugs.php.net/bug.php?id=66830&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=66830&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=66830&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=66830&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=66830&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=66830&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=66830&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=66830&r=needscript Try newer version: https://bugs.php.net/fix.php?id=66830&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=66830&r=support Expected behavior: https://bugs.php.net/fix.php?id=66830&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=66830&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=66830&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=66830&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=66830&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=66830&r=dst IIS Stability: https://bugs.php.net/fix.php?id=66830&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=66830&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=66830&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=66830&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=66830&r=mysqlcfg
