Claude Code v2.1.246

Directory sync pins checkouts to unconverted line endings

You'll notice
Useful3 Signal2
Directory Sync

Directory sync disables line-ending conversion and filters so files aren't silently rewritten in transit.

What

Before syncing a directory, Claude Code appends a rule to the repository's attributes file turning off CRLF conversion, clean/smudge filters, ident expansion and working-tree encoding, so files are not silently rewritten in transit.

Details
  • The attributes file is opened without following symlinks and with a size cap.
  • If it is not a plain file of modest size, sync warns and continues without pinning.
  • Failures warn and report false rather than aborting the sync.
Evidence

dir-sync: cannot pin the checkout to unconverted line endings:

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