From: nosp at m dot net Operating system: Debian 64 PHP version: 5.2.9 PHP Bug Type: Feature/Change Request Bug description: copy() may result in data loss
Description: ------------ copying a large file to itself result in a 64ko truncated file Reproduce code: --------------- $somepath = [path_to_a_file]; copy($somepath, $somepath); Expected result: ---------------- leave somefile unaltered Actual result: -------------- on Debian 64-bit (not on OS X Leopard), any file > 64ko copied to itself result in a 64ko file. i suppose that's because it copies files by 64ko blocks and writes block per block so after the first block copy, the source is 64ko length. as it can result in data loss and copying a file to itself should do nothing, i propose to raise a warning and do nothing when copy has the same path for source and dest. -- Edit bug report at http://bugs.php.net/?id=47758&edit=1 -- Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=47758&r=trysnapshot52 Try a CVS snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=47758&r=trysnapshot53 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=47758&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=47758&r=fixedcvs Fixed in CVS and need be documented: http://bugs.php.net/fix.php?id=47758&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=47758&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=47758&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=47758&r=needscript Try newer version: http://bugs.php.net/fix.php?id=47758&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=47758&r=support Expected behavior: http://bugs.php.net/fix.php?id=47758&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=47758&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=47758&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=47758&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=47758&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=47758&r=dst IIS Stability: http://bugs.php.net/fix.php?id=47758&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=47758&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=47758&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=47758&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=47758&r=mysqlcfg
