Req #73433 [NEW]: could posix_fadvice be added?

From: divinity76 at gmail dot com Operating system: unix* PHP version: Next Minor Version Package: POSIX related Bug Type: Feature/Change Request Bug description:could posix_fadvice be added? Description: ------------ a php script doing file opretaions might benefit from posix_fadvice, could that be added? additional note: it might be worth looking into adding posix_fadvice calls to file_put_contents / file_get_contents , namely POSIX_FADV_SEQUENTIAL, because those always are. Test script: --------------- <?php $fp=fopen('bigfile','rb'); // tell the kernel that i'm probably only going to access this data once, // so it's probably a waste to add this to the filesystem cache posix_fadvice($fp,0,0,POSIX_FADV_NOREUSE); // tell the kernel that i'm probably going to read from byte 12345 to 123456789 sequentially, so optimize for that posix_fadvice($fp,12345,123456789,POSIX_FADV_SEQUENTIAL); fseek($fp,12345); $content=fread($fp,123456789-12345); fclose($content); // aka file_get_contents('bigfile',false,NULL,12345,123456789-12345); -- Edit bug report at https://bugs.php.net/bug.php?id=73433&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=73433&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=73433&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=73433&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=73433&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=73433&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=73433&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=73433&r=needscript Try newer version: https://bugs.php.net/fix.php?id=73433&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=73433&r=support Expected behavior: https://bugs.php.net/fix.php?id=73433&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=73433&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=73433&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=73433&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=73433&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=73433&r=dst IIS Stability: https://bugs.php.net/fix.php?id=73433&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=73433&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=73433&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=73433&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=73433&r=mysqlcfg
