Bug #69442 [NEW]: proc_open with PTY closes incorrect filedescriptor

From: jthijssen+php at noxlogic dot nl Operating system: Ubuntu PHP version: 5.6.8RC1 Package: Program Execution Bug Type: Bug Bug description:proc_open with PTY closes incorrect filedescriptor Description: ------------ proc_open in combination with PTY support (by default disabled and unconfigurable, but patched by Debian/Ubuntu), will close file the /dev/ptmx file descriptor AFTER the other file descriptors have been dup2()'ed. This causes issues when such a file descriptor happens to have the same file descriptor as the /dev/ptmx one, which happens often. This causes some issues in some tests of Symfony2 where I dove into to find the problem: https://github.com/symfony/symfony/issues/12643#issuecomment-92279343 Test script: --------------- Code can be found at: https://github.com/symfony/symfony/issues/12643#issuecomment-92279343 -- Edit bug report at https://bugs.php.net/bug.php?id=69442&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=69442&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=69442&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=69442&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=69442&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=69442&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=69442&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=69442&r=needscript Try newer version: https://bugs.php.net/fix.php?id=69442&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=69442&r=support Expected behavior: https://bugs.php.net/fix.php?id=69442&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=69442&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=69442&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=69442&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=69442&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=69442&r=dst IIS Stability: https://bugs.php.net/fix.php?id=69442&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=69442&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=69442&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=69442&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=69442&r=mysqlcfg
