Bug 151570 – Add an API for getting the branch identifier from a Git or SVN checkout.

• Component: Tools / Tests
• Status: RESOLVED FIXED

[Matthew Hanson]

VCSUtils.pm knows how to extract the remote URL from SVN and Git repositories, but it does not expose this function publicly. In fact, the logic for doing this is embedded in another function called pathRelativeToSVNRepositoryRootForPath. This makes it difficult for VCSUtils clients to determine the branch identifier (e.g. "trunk", "Safari-601.1.46.1", "safari-601.1.46-branch") of a repository.

This bug tracks exposing an API for getting such an identifier, given a path to a repository.

Fixed.

I've turned off the automatic whitespace trimming in my editor.

The final patch makes svnInfoForPath safe to use with paths that are not the current working directory.

Sorry this took so long to review!

BTW, there are unit tests for VCSUtils.pm here:

  Tools/Scripts/webkitperl/VCSUtils_unittest/

For the subroutines that just extract data from command output, it might be nice to write a couple tests with output from actual SVN or git WebKit repository checkouts.

Testing the methods that run shell commands would be much more difficult since we don't have a way to mock shell commands to run.
