note 88226 added to function.copy

Function copy() has a bug (or strange behavior). When you copy file to _already_ existed file-target, then info of this file-target will be cached before rewrite. So, for example, result of code: ------------------ <?php $source = '/t1.t'; $target = '/t2.t'; file_put_contents($source, 'aaaaaaaaaa'); file_put_contents($target, 'a'); clearstatcache( true ); copy( $source, $target ); var_dump( filesize($target) ); ------------------ will be: ------------------ int(1) ------------------ instead of expected: ------------------ int(10) ------------------ Workaround here is usage of clearstatcache(). Also other problem is that copy() function is not listed in list of cached functions in manual for clearstatcache(). I hope this info will help. P.S.: as i understand from source code, the problem is that copy() uses php_stream_stat_path_ex() [ _php_stream_stat_path() ] function which stores stat info in cache. Correct solutions are: 1. add parameter to php_stream_stat_path_ex() to not store info to cache and call it for destination path in php_copy_file_ex() 2. clear cache after successfull call of php_stream_stat_path_ex() for destination path in php_copy_file_ex(). ---- Server IP: 69.147.83.197 Probable Submitter: 195.82.157.101 ---- Manual Page -- http://www.php.net/manual/en/function.copy.php Edit -- https://master.php.net/note/edit/88226 Del: integrated -- https://master.php.net/note/delete/88226/integrated Del: useless -- https://master.php.net/note/delete/88226/useless Del: bad code -- https://master.php.net/note/delete/88226/bad+code Del: spam -- https://master.php.net/note/delete/88226/spam Del: non-english -- https://master.php.net/note/delete/88226/non-english Del: in docs -- https://master.php.net/note/delete/88226/in+docs Del: other reasons-- https://master.php.net/note/delete/88226 Reject -- https://master.php.net/note/reject/88226 Search -- https://master.php.net/manage/user-notes.php
