Bug #72182 [NEW]: \SplFileObject::getSize() returns 0 for files created with tempnam()

From: bishop Operating system: Linux 4.1.17-22.30.amzn1.x86_64 PHP version: 5.6.21 Package: SPL related Bug Type: Bug Bug description:\SplFileObject::getSize() returns 0 for files created with tempnam() Description: ------------ \SplFileObject does not seem to treat file names created by tempnam() the same as file names created manually. In the latter case, \SplFileObject::getSize() reports the correct on-disk size during write operations as well as subsequent reads. The former case, however, returns 0 consistently. HHVM appears to operate as expected. See also https://3v4l.org/vLlb0 Test script: --------------- $paths = [ sys_get_temp_dir() . DIRECTORY_SEPARATOR . 'bishop', tempnam(sys_get_temp_dir(), 'bishop'), ]; foreach ($paths as $path) { $fileW = new \SplFileObject($path, 'w'); $fileW->fputcsv(range(0,2)); assert(6 === $fileW->getSize()); echo $fileW->getSize() . PHP_EOL; $fileR = new \SplFileObject($path, 'r'); assert(6 === $fileR->getSize()); echo $fileR->getSize() . PHP_EOL; } Expected result: ---------------- 6 6 6 6 Actual result: -------------- 6 6 PHP Warning: assert(): Assertion failed ... 0 PHP Warning: assert(): Assertion failed ... 0 -- Edit bug report at https://bugs.php.net/bug.php?id=72182&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=72182&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=72182&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=72182&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=72182&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=72182&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=72182&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=72182&r=needscript Try newer version: https://bugs.php.net/fix.php?id=72182&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=72182&r=support Expected behavior: https://bugs.php.net/fix.php?id=72182&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=72182&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=72182&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=72182&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=72182&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=72182&r=dst IIS Stability: https://bugs.php.net/fix.php?id=72182&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=72182&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=72182&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=72182&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=72182&r=mysqlcfg
