this is a very simple extension to os.walk to optionally walk down into symlink directories, when it is supported by the operating system. This patch keeps a compatible interface by having this option disabled.

Logged In: YES user_id=1188172 The docs to os.walk say: """ Note: On systems that support symbolic links, links to subdirectories appear in dirnames lists, but walk() will not visit them (infinite loops are hard to avoid when following symbolic links). To visit linked directories, you can identify them with os.path.islink(path), and invoke walk(path) on each directly. """ Nevertheless, we could offer this option with a caution message.

I'm not sure if this is a good idea; although I am certain it would be useful at times. Dangerous! But if its documented, ... and there's our problem :) Patch applies cleanly to the HEAD, but needs documentation.

Added docs and tests and committed in rev. 54407.

The test suite patch (54482) broke the windows build. The assertion self.assertEqual(len(all), 4) fails because it finds 5 directories (link is a directory), then the rest of the code is not executed. In turn, the tear-down code is not run, leaving the directories behind. This causes subsequent tests to fail. When fixing the code, I recommend to move the tear-down code into the tearDown method of the test, to make sure it is always run.

Here is a patch that fixes test_os.WalkTests on Windows. I also added a tearDown method to WalkTests and removed Collin's changes to MakedirTests, because they are not needed anymore. File Added: test_os.diff

Is there a separate bug for doc updates for this?

Hi Trent, There is no separate issue yet. What is missing in the docs? Georg updated the docs when he checked in this patch.

Ziga, My mistake: I failed to notice the change to Doc/lib/libos.tex.
