#27865 [NEW]: CLI PHP: STDIN/OUT/ERR are not the good fd's

From: bernard at kuantic dot com Operating system: Linux Fedora Core 1 PHP version: 5.0.0RC1 PHP Bug Type: Filesystem function related Bug description: CLI PHP: STDIN/OUT/ERR are not the good fd's Description: ------------ Hello. I'm trying to run a php script from xinetd (Fedora Linux). I need to close stdin, stdout & stderr since I want to close the socket established with the caller process (I have a long processing to do locally, I need to release a remote resource & closing the connection is the only way I can do it). I've tried : fclose(STDIN); fclose(STDOUT); fclose(STDERR); It does not work, the socket is still up & running. When I run strace(1), I see that I'm closing fds 4, 5 & 6 (fd 3 is the fd of the script being read) and not fd 0, 1 & 2. It seems that CLI PHP calls dup(2) to get duplicates of fd 0, 1 & 2 and so these 3 fds are totally unreachable from the script itself. I'm not used to php source code, but I think that the problem comes from getting constants STDIN, STDOUT & STDERR thru filter code generation used by "php://stdin" etc. and no provision is done for the first calls: a dup(2) is automatically used. So constants STDIN, STDOUT & STDERR are not pointing to the correct fd's, but dup's. -- Edit bug report at http://bugs.php.net/?id=27865&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=27865&r=trysnapshot4 Try a CVS snapshot (php5): http://bugs.php.net/fix.php?id=27865&r=trysnapshot5 Fixed in CVS: http://bugs.php.net/fix.php?id=27865&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=27865&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=27865&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=27865&r=needscript Try newer version: http://bugs.php.net/fix.php?id=27865&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=27865&r=support Expected behavior: http://bugs.php.net/fix.php?id=27865&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=27865&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=27865&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=27865&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=27865&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=27865&r=dst IIS Stability: http://bugs.php.net/fix.php?id=27865&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=27865&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=27865&r=float
