Req #73340 [NEW]: SHMOP: Access to SHM_LOCK, SHM_UNLOCK

From: narf at devilix dot net Operating system: PHP version: Irrelevant Package: POSIX related Bug Type: Feature/Change Request Bug description:SHMOP: Access to SHM_LOCK, SHM_UNLOCK Description: ------------ I was looking for a way to store encryption keys in (guaranteed to be non-swap) memory, and apparently setting the SHM_LOCK flag on a shared memory segment seems to be the only way to do that. Obviously, PHP doesn't expose shmctl() directly and that's probably for a good reason, but can we have something like shmop_lock(), or an optional parameter to shmop_open()? (on a related note, shmop_stat() would be nice too) -- Edit bug report at https://bugs.php.net/bug.php?id=73340&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=73340&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=73340&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=73340&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=73340&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=73340&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=73340&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=73340&r=needscript Try newer version: https://bugs.php.net/fix.php?id=73340&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=73340&r=support Expected behavior: https://bugs.php.net/fix.php?id=73340&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=73340&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=73340&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=73340&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=73340&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=73340&r=dst IIS Stability: https://bugs.php.net/fix.php?id=73340&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=73340&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=73340&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=73340&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=73340&r=mysqlcfg
