Improve CPU speed in Python program

Create a unit test that replicates this performance bug and then fix it. https://bugs.launchpad.net/bleachbit/+bug/1265963 The source code is here [login to view URL] I think the problem is related to this complicated pattern in the [login to view URL] file which gets translated to a regular expression, which may be needlessly re-compiled for each file. FileKey1=%ProgramFiles%\Steam\steamapps|*.mdmp;*.tmp;*.dmp;*.icns;.DS_Store;logfile.*;*.log;[login to view URL];[login to view URL];*[login to view URL];log*.txt|RECURSE The problem is most obvious when there are many files,so in the unit test, make lots of empty files. In the unit test, create a small [login to view URL] file where the FileKey points to a temporary directory. SUBMISSION Your choice: GitHub pull request, Patch format, or .py files ACCEPTANCE CRITERIA The code is 75% faster (which seems reasonable based on user's comparison with another application). COPYRIGHT For your paid work, you will surrender the copyright, which will be open sourced. Thank you. ENVIRONMENT * Python 2.5, 2.6, or 2.7 * The application is PyGTK, but you should not PyGTK for this project. * It may be possible to do this job under Linux, but Windows is preferred.
