Claude Code v2.1.248

Large directory-sync downloads survive an expired token mid-transfer

You'll notice
Useful3 Signal2
Directory Sync

Big sync downloads now resume after a token expires mid-transfer instead of restarting.

What

When Claude Code downloads a file directly during a directory sync, a token expiring partway through no longer restarts or corrupts the transfer. Bytes already received are kept, a fresh read token is fetched, and the download resumes from where it stopped.

Details
  • New read tokens are only issued while the transfer is actually making progress, so a stuck download cannot loop forever.
  • The file's etag is checked to be unchanged between attempts; if the file changed on the server the download does not silently splice two versions.
  • A stall timeout parameter was added.
  • Giving up produces a warning naming exactly how many bytes of the file had arrived.
Evidence

dir-sync: direct download gave up after ${A} read tokens at ${O.received} of ${r.size} bytes

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