Bug #70819 [NEW]: bzopen/fopen is not rewinded when accessing a file for the second time

From: mail at jerrygrey dot me Operating system: Irrelevant PHP version: Irrelevant Package: Streams related Bug Type: Bug Bug description:bzopen/fopen is not rewinded when accessing a file for the second time Description: ------------ This looks like an old bug (from 12 years ago) first appearing here: http://php.net/manual/en/function.fflush.php#28887 It has reappeared via https://github.com/php/php-src/pull/1553 The function bzopen should automatically rewind the file pointer as per fopen() documentation for "r" mode: "...place the file pointer at the beginning of the file", but it doesn't. If this is by design, it should be included in the documentation. Since fopen is the base for bzopen, it might have the same issue too. Test script: --------------- <?php $file = __DIR__ . DIRECTORY_SEPARATOR . 'bzflush_test.txt.bz2'; $text = "This is a test string."; $bz1 = bzopen($file, 'w'); bzwrite($bz1, $text); var_dump(bzflush($bz1)); $bz2 = bzopen($file, 'r'); var_dump(bzread($bz2)); bzclose($bz2); bzclose($bz1); ?> Expected result: ---------------- bool(true) string(22) "This is a test string." Actual result: -------------- bool(true) string(0) "" -- Edit bug report at https://bugs.php.net/bug.php?id=70819&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=70819&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=70819&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=70819&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=70819&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=70819&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=70819&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=70819&r=needscript Try newer version: https://bugs.php.net/fix.php?id=70819&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=70819&r=support Expected behavior: https://bugs.php.net/fix.php?id=70819&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=70819&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=70819&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=70819&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=70819&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=70819&r=dst IIS Stability: https://bugs.php.net/fix.php?id=70819&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=70819&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=70819&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=70819&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=70819&r=mysqlcfg
