Edit report at https://bugs.php.net/bug.php?id=71630&edit=1 ID: 71630 Updated by: danack@php.net Reported by: vladimir at volomp dot com Summary: copy function does not work if destination file does not exist -Status: Open +Status: Feedback Type: Bug Package: *General Issues Operating System: linux/all PHP Version: 5.5.32 Block user comment: N Private report: N New Comment: > When file does not exist, should -1 as 'non-statable stream' be expected, I believe that is correct. > Is it php_stream_stat_path_ex() supposed to return 0 if file is not found? I believe the return values mirror those of standard system stat calls - 0 indicates success, other values a errors. http://linux.die.net/man/2/stat If you're not seeing the error on git 5.5.32, then you'll need to isolate where the error has been introduced as we are unable to reproduce it. Previous Comments: ------------------------------------------------------------------------ [2016-02-19 14:03:31] vladimir at volomp dot com Seems that git 5.5.32 works just fine, as expected. I do have other patches inside, as this is redhat based rpm. Sorry, off I go to check further. But still I do not understand how could it possibly work with this switch/case? When file does not exist, should -1 as 'non-statable stream' be expected, or some other error code? ------------------------------------------------------------------------ [2016-02-19 13:56:09] vladimir at volomp dot com I have patched my server with same check as in 5.2.17 and it now works flawlessly. Could somebody explain how could this actually work? Is it php_stream_stat_path_ex() supposed to return 0 if file is not found? This code just doesn't seem right. ------------------------------------------------------------------------ [2016-02-19 13:48:27] danack@php.net Please can you confirm that you don't have any security modules active that would prevent creation of new files - such as SELinux or Suhosin? I think it is far more likely that it is some problem unique to your computer rather than a general bug with copy(). ------------------------------------------------------------------------ [2016-02-19 13:38:08] vladimir at volomp dot com Your script is just fine for testing. I get bool(false) consistently. php --version PHP 5.5.16 (cli) (built: Aug 31 2014 16:22:37) Copyright (c) 1997-2014 The PHP Group Zend Engine v2.5.0, Copyright (c) 1998-2014 Zend Technologies with Zend OPcache v7.0.4-dev, Copyright (c) 1999-2014, by Zend Technologies <?php file_put_contents("a.txt", "These are some words"); copy("a.txt", "b.txt"); var_dump(file_exists("b.txt")); I will git clone and check completely stock .32 ------------------------------------------------------------------------ [2016-02-19 13:28:37] danack@php.net Please can you provide some context of how you are encountering a problem. i.e. provide a reproduce scripts. The code below works for me: <?php file_put_contents("a.txt", "These are some words"); copy("a.txt", "b.txt"); var_dump(file_exists("b.txt")); //output is bool(true) without b.txt existing first. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
