Bug #16211: ftruncate() won't truncate file

From: web-php-bugs@sklar.com Operating system: Red Hat Linux 7.1 / kernel 2.4.4 PHP version: 4.0CVS-2002-03-21 PHP Bug Type: Filesystem function related Bug description: ftruncate() won't truncate file Under the latest CVS, the following script fails (ftruncate() returns an error and doesn't truncate the file) but under PHP 4.1.2, it works fine: <?php if (! $fp = fopen('test','r+')) { die("Can't open test"); } if (! ftruncate($fp,0)) { die("Can't truncate"); } fclose($fp); ?> (The file "test" exists and has some text in it.) I get the same results whether the mode passed to fopen() is "r", "r+", "a", or "a+" (with "w" or "w+", the call to ftruncate() still fails, but the file is truncated due to the nature of the "w" fopen mode). -- Edit bug report at http://bugs.php.net/?id=16211&edit=1 -- Fixed in CVS: http://bugs.php.net/fix.php?id=16211&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=16211&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=16211&r=needtrace Try newer version: http://bugs.php.net/fix.php?id=16211&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=16211&r=support Expected behavior: http://bugs.php.net/fix.php?id=16211&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=16211&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=16211&r=submittedtwice
