#50657 [NEW]: copy() with an empty (zero-byte) HTTP source succeeds but returns false

From: php at lorddeath dot net Operating system: Win32/Linux PHP version: 5.3SVN-2010-01-04 (snap) PHP Bug Type: Filesystem function related Bug description: copy() with an empty (zero-byte) HTTP source succeeds but returns false Description: ------------ The copy() function returns false (but otherwise succeeds in copying the file) when the source file is accessed via a HTTP stream, but is empty (zero bytes). Other, non-HTTP, stream types might also be affected, but local files are definitely *NOT* affected. I have successfully reproduced this bug with PHP 5.2.9 on Linux, and 5.2.5, 5.2.12, 5.3.0, 5.3.1 and 5.3.3-dev (2010-Jan-04 15:00:00) on Windows. (I will keep the empty.txt URL in the reproduce code accessible for a while.) Reproduce code: --------------- $r = copy("http://lspace.sihnon.net/pub/empty.txt", "temp"); var_dump($r); Expected result: ---------------- bool(true) Actual result: -------------- bool(false) -- Edit bug report at http://bugs.php.net/?id=50657&edit=1 -- Try a snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=50657&r=trysnapshot52 Try a snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=50657&r=trysnapshot53 Try a snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=50657&r=trysnapshot60 Fixed in SVN: http://bugs.php.net/fix.php?id=50657&r=fixed Fixed in SVN and need be documented: http://bugs.php.net/fix.php?id=50657&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=50657&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=50657&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=50657&r=needscript Try newer version: http://bugs.php.net/fix.php?id=50657&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=50657&r=support Expected behavior: http://bugs.php.net/fix.php?id=50657&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=50657&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=50657&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=50657&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=50657&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=50657&r=dst IIS Stability: http://bugs.php.net/fix.php?id=50657&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=50657&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=50657&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=50657&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=50657&r=mysqlcfg
