From: rc at opelgt dot org Operating system: Mac OS 10.4.11 PHP version: 4.4.7 PHP Bug Type: Filesystem function related Bug description: Fread isnt able to read
Description: ------------ Although the pointer is at position 0 and filesize is cached with the value of 4 fread reads nothing. A clearstatcache is necessary for fread to operate correct. Reproduce code: --------------- <?php $str1 = '1234'; $str2 = '56'; $datei = 'test.txt'; $dh = fopen ($datei,"w"); fwrite($dh, $str1); fclose($dh); $dh = fopen ($datei,"r+"); echo 'content: '.fread($dh, filesize($datei))."<BR>\n"; echo 'pointer after write at: '.ftell($dh).'<br>'; ftruncate($dh, '0'); echo 'pointer after truncate at: '.ftell($dh).'<br>'; echo 'filesize after truncate is: '.filesize($datei).'<br>'; fwrite($dh, $str2); echo 'pointer after second write at: '.ftell($dh).'<br>'; rewind($dh); echo 'pointer after rewind at: '.ftell($dh).'<br>'; echo 'content: '.fread($dh, filesize($datei)).'<br>'; clearstatcache(); echo 'content: '.fread($dh, filesize($datei)); fclose($dh); ?> Expected result: ---------------- content: 1234 pointer after write at: 4 pointer after truncate at: 4 filesize after truncate is: 4 pointer after second write at: 6 pointer after rewind at: 0 content: 56 content: 56 Actual result: -------------- content: 1234 pointer after write at: 4 pointer after truncate at: 4 filesize after truncate is: 4 pointer after second write at: 6 pointer after rewind at: 0 content: content: 56 -- Edit bug report at http://bugs.php.net/?id=43729&edit=1 -- Try a CVS snapshot (PHP 4.4): http://bugs.php.net/fix.php?id=43729&r=trysnapshot44 Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=43729&r=trysnapshot52 Try a CVS snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=43729&r=trysnapshot53 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=43729&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=43729&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=43729&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=43729&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=43729&r=needscript Try newer version: http://bugs.php.net/fix.php?id=43729&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=43729&r=support Expected behavior: http://bugs.php.net/fix.php?id=43729&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=43729&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=43729&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=43729&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=43729&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=43729&r=dst IIS Stability: http://bugs.php.net/fix.php?id=43729&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=43729&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=43729&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=43729&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=43729&r=mysqlcfg
