Oversized files rejected without reading them fully

Reading an oversized file fails fast instead of eating memory.

What probably matters to youSection of the release
What

The Read tool no longer loads an entire file before deciding it is too big. Both the sync and async paths now read at most one byte past the limit and fail on the bytes actually read, so reading a huge file no longer costs the memory of the whole file.

Details
  • Failure is still reported as a file-too-large error.
  • The size check now lives in a single shared helper used by both paths.
Evidence

File exceeds maxBytes limit

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