Details

Summary

Ref T13098. Currently, WorkingCopyIdentity has rules for finding .git/.svn/.hg directories and .arcconfig files. It also has a ton of logic for reading and writing config files.

Generally:

  • Rename WorkingCopyIdentity to WorkingCopy.
  • Make it an abstract base with Git, Mercurial and Subversion subclasses, using the standard module/extension pattern.
  • Throw out almost all of the config file logic. This logic is going to move into Config classes. It is not unique to working copies.
    • Working copies retain the actual bit of this they need: knowing where stuff should go on disk.

This doesn't run yet, but sure looks a lot cleaner!

Test Plan

Doesn't run yet, since Config isn't working yet.

One thing I'm dropping here that I don't explicitly plan to restore is all the logging. I may or may not put that back, depending on how things go and what feedback we see. I think I added it to make my job debugging some theoretical future issue easier, but that issue never materialized.

Nice catches! I managed to catch those later but not before the code actually hit them and died. ๐Ÿฆ‚
