#38678 [NEW]: APC docs need mmap infos

From: thomas-lists at mysnip dot de Operating system: Linux PHP version: Irrelevant PHP Bug Type: Documentation problem Bug description: APC docs need mmap infos Description: ------------ coming from http://news.php.net/php.pecl.dev/4095 pointed here from http://news.php.net/php.pecl.dev/4096 The APC docs don't tell anything about how memory is used in mmap mode. e.g. that - maximum shm-segment-size told in /proc/sys/kernel/shmmax isn't in effect here - mmap uses only one segment and currently uses only the size specified in apc-config for the shm-segments (see bug http://pecl.php.net/bugs/bug.php?id=8609 , maybe that changes) - currently one can only guess which mode is used but I think the phpinfo tells at least "mmap is enabled" ( see bug http://pecl.php.net/bugs/bug.php?id=8608 at pecl.php.net) As mmap-mode is the default nowadays in apc it would be good to tell some more about its configuration :). If one could add the pros/cons of using mmap over shm it would be great too! -- Edit bug report at http://bugs.php.net/?id=38678&edit=1 -- Try a CVS snapshot (PHP 4.4): http://bugs.php.net/fix.php?id=38678&r=trysnapshot44 Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=38678&r=trysnapshot52 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=38678&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=38678&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=38678&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=38678&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=38678&r=needscript Try newer version: http://bugs.php.net/fix.php?id=38678&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=38678&r=support Expected behavior: http://bugs.php.net/fix.php?id=38678&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=38678&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=38678&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=38678&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=38678&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=38678&r=dst IIS Stability: http://bugs.php.net/fix.php?id=38678&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=38678&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=38678&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=38678&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=38678&r=mysqlcfg
