Claude Code v2.1.222

Git diffs ignore external diff drivers and textconv filters

You'll notice
Useful3 Signal0
Git not in their notes

Diffs now ignore your repo's custom diff drivers, so Claude sees the real file contents.

--no-ext-diff--no-textconv
What

Diff reads now pass --no-ext-diff and --no-textconv, so a repo's own git configuration cannot change the content Claude sees when computing patches.

Details
  • New exported constant RAW_BLOB_DIFF_FLAGS = ["--no-ext-diff", "--no-textconv"].
  • Spread into the git diff invocations used for whole patches and per-file hunks.
  • Includes the --no-optional-locks diff calls, which previously passed no such flags.
Evidence

RAW_BLOB_DIFF_FLAGS

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
