#3186 closed bug (fixed)

BDirectory::Contains() is broken for certain cases of similar paths

Reported by: anevilyak Owned by: axeld
Priority: normal Milestone: R1
Component: Kits/Storage Kit Version: R1/pre-alpha1
Keywords: Cc:
Blocked By: Blocking:
Platform: All

Description (last modified by anevilyak)

Steps to reproduce:

  1. Create a directory called New Folder.
  2. Create a directory called New Folder 2.
  3. Get a BDirectory object for New Folder, a BEntry for New Folder 2, and call BDirectory::Contains() on the resulting entry. It will (incorrectly) return true, because Contains currently compares the paths of the two up to the length of the directory itself. Attached please find a patch intended to fix the situation by comparing the path components individually.

On second thought, that patch is flawed also, give me some time to rework.

Updated patch attached, let me know if you see any problems with it, or perhaps a better way to accomplish it, otherwise I can commit that.

Isn't that a bit too complicated? I think all that's missing is a check if the other path actually ends at that point, ie. has a '/' at that position or not.

Indeed, you're right, thanks for reviewing! Sometimes it's easy to miss the obvious :) Fixed in hrev28754.
