From: Operating system: Ubuntu 11.04 PHP version: 5.3.8 Package: Streams related Bug Type: Bug Bug description:fread does not fail when operating on a write only stream
Description: ------------ fread does not throw or generate any error when attempting to read from a write only file stream. Test script: --------------- <?php $tmp = tempnam(sys_get_temp_dir(), 'test_'); $stream = fopen($tmp, 'w'); $data = ""; while(!feof($stream)){ if(false === ($data .= fread($stream, 8192))){ break; }; } ?> Expected result: ---------------- Either feof to return false indicating end of file Or fread erroring or returning false as a result of attempting to read a write-only stream. Actual result: -------------- An infinite loop will occur. feof will never end (doesn't reach the end of the file because it's in write mode) fread will never error despite attempting to read from a write only stream. -- Edit bug report at https://bugs.php.net/bug.php?id=60671&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=60671&r=trysnapshot54 Try a snapshot (PHP 5.3): https://bugs.php.net/fix.php?id=60671&r=trysnapshot53 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=60671&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=60671&r=fixed Fixed in SVN and need be documented: https://bugs.php.net/fix.php?id=60671&r=needdocs Fixed in release: https://bugs.php.net/fix.php?id=60671&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=60671&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=60671&r=needscript Try newer version: https://bugs.php.net/fix.php?id=60671&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=60671&r=support Expected behavior: https://bugs.php.net/fix.php?id=60671&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=60671&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=60671&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=60671&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=60671&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=60671&r=dst IIS Stability: https://bugs.php.net/fix.php?id=60671&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=60671&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=60671&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=60671&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=60671&r=mysqlcfg
