Patch Changes

• 60feee3: Stream uploads instead of buffering streaming input entirely in memory:

  • Sandbox.files.write() / write_files(): ReadableStream data (JS, outside the browser) and file-like objects (Python) are streamed to the sandbox, including when gzip is enabled (compression now happens chunk by chunk). useOctetStream/use_octet_stream now defaults to auto-detect — octet-stream is used when any entry is streamable (so streamed uploads aren't silently buffered) and multipart/form-data otherwise; browsers always use multipart/form-data. A streamed upload is bounded by a per-chunk timeout on the wire (Python's per-write httpx timeout, default the request timeout); a stalled upload that this can't observe is bounded server-side. On Python's AsyncSandbox, the blocking file reads and gzip compression of a streamed upload now run in a worker thread so a large upload doesn't stall the event loop.
  • Sandbox.files.read(format="stream"): the request timeout now bounds only the initial handshake instead of killing the stream while it's being consumed. The body is bounded by a per-chunk idle timeout on the wire (streamIdleTimeoutMs in JS, stream_idle_timeout in Python, default the request timeout — 60s — 0/None to disable): it aborts only when the server stops sending mid-stream, and a slow or paused consumer never trips it (a held-but-unread stream is reclaimed server-side). Use signal (JS) to cancel an in-flight stream. A dropped connection during the stream handshake now surfaces the same typed, health-checked error as non-stream reads. The stream holds a pooled connection until it is consumed to the end, cancelled/closed, errors, or the idle timeout fires — consume it fully, use the context manager, or close it.
  • Python Sandbox.files.read(format="stream"): the response body is now streamed from the sandbox instead of being downloaded into memory before iteration (sync and async).
  • JS Sandbox.files.read() with blob or stream format now returns an empty Blob/ReadableStream for empty files instead of "".

• c1415f3: Stream volume file uploads and downloads instead of buffering in memory:

  • Volume.writeFile() / Volume.write_file(): ReadableStream data (JS, outside the browser) and file-like objects (Python) are now streamed to the API in chunks.
  • Volume.readFile(format="stream") / read_file(format="stream"): the request timeout now bounds only the initial handshake instead of killing the stream while it's being consumed (Python disables the read timeout; JS bounds the handshake and supports signal to cancel an in-flight stream). A dropped connection during the stream handshake now surfaces the same typed, health-checked error as non-stream reads.
