[jira] [Created] (IO-739) RegexFileFilter matches on path instead of name

[Hugo Zwaal (Jira)]

Hugo Zwaal created IO-739:
-----------------------------

             Summary: RegexFileFilter matches on path instead of name
                 Key: IO-739
                 URL: https://issues.apache.org/jira/browse/IO-739
             Project: Commons IO
          Issue Type: Bug
          Components: Filters
    Affects Versions: 2.9.0
            Reporter: Hugo Zwaal
         Attachments: ListFilesRegexBug.java

The new RegexFileFilter.accept(Path, BasicFileAttributes) uses the full path 
for matching. When this filter is used in combination with 
FileUtils.listFiles(File, IOFileFilter, IOFileFilter), then it will not match 
anything if a path separator is not part of the pattern.

The following small program will list all files when used with version 2.8.0 
and nothing when used with version 2.9.0:

{color:#770055}import 
{color}{color:#339999}org.apache.commons.io.FileUtils{color};
{color:#770055}import 
{color}{color:#339999}org.apache.commons.io.filefilter.{color}*;

{color:#770055}import {color}{color:#339999}java.io.File{color};
{color:#770055}import {color}{color:#339999}java.util.Collection{color};

{color:#770055}class {color}{color:#339999}ListFilesRegexBug {color}{
   {color:#770055}public static void {color}main({color:#339999}String{color}[] 
{color:#660088}args{color}) {
     {color:#339999}RegexFileFilter {color}{color:#6688ff}filter {color}= 
{color:#770055}new 
{color}RegexFileFilter({color:#0000cc}"[^/{color}{color:#cc88ff}\\\\{color}{color:#0000cc}]+"{color});
     {color:#339999}Collection{color}<{color:#339999}File{color}> 
{color:#6688ff}files {color}= 
{color:#339999}FileUtils{color}.{color:#575757}listFiles{color}({color:#770055}new
 {color}File({color:#0000cc}"."{color}), {color:#6688ff}filter{color}, 
{color:#339999}TrueFileFilter{color}.{color:#0000aa}TRUE{color});
     {color:#770055}for {color}({color:#339999}File {color}{color:#6688ff}f 
{color}: {color:#6688ff}files{color}) {
       
{color:#339999}System{color}.{color:#0000aa}out{color}.println({color:#6688ff}f{color}.getAbsolutePath());
     }
   }
}
