Description

When a RepositoryTool is applying the review's patches to the cloned
repository, it simply writes using open(p, 'wb'). This does not create
directories that the patch implies.

This leads to the write failing with:
IOError: [Errno 2] No such file or directory: u'dir/file'

This patch creates directories for each file if the path does not exist
already.

Testing Done

Replciated the error by posting a review for a file in a new directory,
applied patch, and RepositoryTool successfully runs on patched files.

This doesn't always create directories -- it ensures they exist, so let's call this ensure_directories.

We never want to use bare except. This can catch things that should never be caught, like KeyboardInterrupt or RuntimeError. Instead, this needs to specify the exact exception we expect, which should be OSError.

alextechcc Oct. 23, 2018, 7:38 p.m.

Should I fix the rest of the instances of this in all related files?

No, that isn't related to your change.
```

Change Summary:

Renamed create_dirs, formatting, and catch OSError instead of bare except.
