Summary

Ref T13522. When changesets update an image, we currently compute no effect hash. A content hash of the image (or other binary file) is a reasonable effect hash, and enalbes effect-hash-based behavior, including hiding files in intradiffs.

Test Plan
  • Created a revision affecting cat.png and quack.txt (currently, there must be 2+ changesets to trigger the hide logic).
  • Updated it with the exact same changes.
  • Viewed revision:
    • Saw the image renderered in the interdiff.
  • Applied patch.
  • Ran bin/differential rebuild-changesets ....
  • Viewed revision:
    • Saw both changesets collapse as unchanged.
