Bug #72343 [NEW]: SplFileInfo from DirectoryIterator opens new FTP connections

From: sander at prezent dot nl Operating system: Linux PHP version: 7.0.7 Package: FTP related Bug Type: Bug Bug description:SplFileInfo from DirectoryIterator opens new FTP connections Description: ------------ Iterating over an FTP directory using \DirectoryIterator and then using the \SplFileInfo is extremely slow. Methods called un the \SplFileInfo object, such as isDir() and isFile() cause PHP to open a new FTP connection under the hood for every file to retrieve file information. This issue becomes more apparent when an FTP server is slow during authentication. Test script: --------------- <?php // Some public FTP servers to use $ftp = 'ftp://speedtest.tele2.net/'; // Fast server //$ftp = 'ftp://ftp.hq.nasa.gov/'; // Not so fast server echo "Testing on $ftp\n"; $it = new NoRewindIterator(new DirectoryIterator($ftp)); foreach ($it as $file) { var_dump($file->isFile()); // This causes new connections and the slowdown } Expected result: ---------------- No constant stream of new FTP connections and better performance. The FTP extension should reuse the connection that was established with the \DirectoryIterator. Also, since \DirectoryIterator already gets an FTP file listing, it probably already knows what it should respond to isFile()/isDir() and other \SplFileInfo method calls. Can that information not simply be reused? -- Edit bug report at https://bugs.php.net/bug.php?id=72343&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=72343&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=72343&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=72343&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=72343&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=72343&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=72343&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=72343&r=needscript Try newer version: https://bugs.php.net/fix.php?id=72343&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=72343&r=support Expected behavior: https://bugs.php.net/fix.php?id=72343&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=72343&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=72343&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=72343&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=72343&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=72343&r=dst IIS Stability: https://bugs.php.net/fix.php?id=72343&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=72343&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=72343&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=72343&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=72343&r=mysqlcfg
