Bug #17885: corrupted file downloads with fpassthru/fread/readfile

From: dariusz@bulgaria.com Operating system: WinXP Pro PHP version: 4.2.1 PHP Bug Type: Apache2 related Bug description: corrupted file downloads with fpassthru/fread/readfile OS: WinXP Pro Apache 2.0.36 PHP 4.2.1 (module) That's my script: $f = "e:/web/old.zip"; header("Content-type: application/zip"); header("Content-Disposition: attachment; filename=old.zip"); header("Content-Length: " . filesize($f)); $fp = fopen($f, "rb"); while (!feof($fp)) { print fread($fp, 1024); } fclose($fp); The script is running on a server in my local 100MBit LAN. The first ~8kB of the downloaded file are always OK, but from there on the file is totally screwed up. Filesize is correct though. Tried the same script with Apache 1.3.26 (also the module version) with basically the same configuration and the download works fine. Switched again to 2.0.36 and the downloads are corrupted again. This seems to happen only with large files (the one I tried is ~11MB). -- Edit bug report at http://bugs.php.net/?id=17885&edit=1 -- Fixed in CVS: http://bugs.php.net/fix.php?id=17885&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=17885&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=17885&r=needtrace Try newer version: http://bugs.php.net/fix.php?id=17885&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=17885&r=support Expected behavior: http://bugs.php.net/fix.php?id=17885&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=17885&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=17885&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=17885&r=globals
