Doc #72521 [NEW]: Document PHP-FPM chroot() issues with the opcode cache

From: janos at pasztor dot at Operating system: Linux/Unix PHP version: Irrelevant Package: Documentation problem Bug Type: Documentation Problem Bug description:Document PHP-FPM chroot() issues with the opcode cache Description: ------------ When using the chroot functionality with PHP-FPM and having the same path within the chroots of two different pools, the opcode cached code can get mixed up. For example these two scripts get mixed up with opcode cache name: Full path 1: /var/www/example1.com/var/www/htdocs/index.php Chroot 1: /var/www/example1.com Full path 2: /var/www/example2.com/var/www/htdocs/index.php Chroot 2: /var/www/example2.com Expected result: ---------------- Update the documentation at https://secure.php.net/manual/en/install.fpm.configuration.php with a warning, something like this: chroot string Chroot to this directory at the start. This value must be defined as an absolute path. When this value is not set, chroot is not used. >>> Be careful when using chroot with opcache! Since the opcache is shared between pools, the paths within the chroots must be unique per chroot, otherwise the opcache will lead to unexpected behavior. <<< (Alternatively the FPM pool name could be added to the opcache key to avoid this behavior.) -- Edit bug report at https://bugs.php.net/bug.php?id=72521&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=72521&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=72521&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=72521&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=72521&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=72521&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=72521&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=72521&r=needscript Try newer version: https://bugs.php.net/fix.php?id=72521&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=72521&r=support Expected behavior: https://bugs.php.net/fix.php?id=72521&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=72521&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=72521&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=72521&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=72521&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=72521&r=dst IIS Stability: https://bugs.php.net/fix.php?id=72521&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=72521&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=72521&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=72521&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=72521&r=mysqlcfg
