Merge lp:~gesha/linaro-license-protection/remove-fallback into lp:~linaro-automation/linaro-license-protection/trunk

[Georgy Redkozubov]

This branch removes fallback support for HOWTOs and adds searching of HOWTOs only in current dir.

[Данило Шеган (danilo)]

In the call to cls.dirEntries, it is unclear what do arguments represent (especially "False"). Python does have one of my favourite features for readability, which is passing arguments by keywords: please use that.

Where you check

         if len(androidpaths) > 0 and len(ubuntupaths) > 0:

you could add an "else" block and get rid of the "else" block in the if below (and replace "elif" simply with "else"): not a big deal, but will move "corner" cases to one if, and actual handling to another.

In tests, I wonder if subdir argument is still needed at all for make_temp_dir?

review: Needs Fixing

Not sure is you meant what I did, but anyway fixed.

Thanks for pointing to this, I forget to remove initially.

Fixes based on review comments

[Данило Шеган (danilo)]

Ok, now that it's clear that second parameter to dirEntries is "subdir", I suppose we can get rid of that as well :)

Also, please provide a string explanation of the error condition where we raise MultipleFilesException.

Removed recursive search based on review.

[Данило Шеган (danilo)]

Other than the exception still missing the string passed in, looks good. Thanks for keeping up with my requests :)

review: Approve
