Description: ------------ When attempting to obtain a directory listing from a Windows FTP server via ls(), the regular expression assigns the string value "<DIR>" to the is_dir attribute of the file's entry in the listing. Unfortunately, the regular expression is structured in such a way that it captures the filesize if the file is not a directory, and any file with a size greater than zero is erroneously tagged as being a directory. This obviously mucks up getRecursive() when the function attempts to descend into a directory that is actually a file. Reproduce code: --------------- The original code, at line 576, is as follows: 'windows' => array( 'pattern' => '/(.+)\s+(.+)\s+((<DIR>)|[0-9]+)\s+(.+)/', 'map' => array('name'=>5,'date'=>1,'is_dir'=>3) ) 3 is an inappropriate match, as it captures either <DIR> or the filesize. It should be match number 4, the (<DIR>) inside match number 3: 'windows' => array( 'pattern' => '/(.+)\s+(.+)\s+((<DIR>)|[0-9]+)\s+(.+)/', 'map' => array('name'=>5,'date'=>1,'is_dir'=>4) )

This bug has been fixed in CVS. If this was a documentation problem, the fix will appear on pear.php.net by the end of next Sunday (CET). If this was a problem with the pear.php.net website, the change should be live shortly. Otherwise, the fix will appear in the package's next release. Thank you for the report and for helping us make PEAR better.
