Summary

SDK-2702 asks for SDK-owned Request, Response and Headers types, a send(request) -> Response adapter protocol, httpx confined to its adapter, and a README that shows how to write an adapter. All of that already landed in #1977 (httpx only inside the adapter, guarded by the import-without-httpx job in the CI workflow) and #1982 (the README). This finishes the ticket by bringing the adapter guide up to date with the per-request timeout that #2010 added after the guide was written.

Changes

• The Request field table lists timeout, and the guide says to raise RequestTimeoutError when it elapses, so every adapter reports a timeout the same way.
• The guide says what to do with credential headers on redirects, pointing at the keeps_credentials and CREDENTIAL_HEADERS helpers the built-in adapters use.
• The requests example passes the timeout through, translates requests.Timeout into RequestTimeoutError, and does not follow redirects.
• supabase_utils.http.errors and supabase_utils.http.redirects appear in the module table.

Verification

Ran the requests example, extracted from the README rather than retyped, through SyncHttpIO against a local http.server: repeated headers join to a, b, a 302 comes back unfollowed, and a slow endpoint raises RequestTimeoutError with the requests.Timeout as its cause.

Linear: SDK-2702

Summary

Summary by CodeRabbit

• Documentation
  • Expanded adapter guidance with request timeout handling and redirect credential filtering.
  • Updated the Requests adapter example to handle timeouts and clarify that redirects are not followed.
  • Added HTTP errors and redirects modules to the module overview.

The README adds http.errors and http.redirects to its module table. It documents the adapter timeout field, the RequestTimeoutError contract, and credential filtering for redirects. The Requests example passes the request timeout, disables automatic redirects, and converts requests.Timeout into RequestTimeoutError.

Possibly related PRs

• supabase/supabase-py#1994: Adds redirect credential helpers and documents credential removal on cross-origin redirects in the same README section.
• supabase/supabase-py#2010: Adds Request.timeout and RequestTimeoutError, which this README documents.

Change: Other

Merge Risk: Moderate · up to e0a85

The example now bounds omitted timeouts and handles response-body timeouts. Before merging, clarify that custom adapters must prevent explicit cookies from crossing origins; following the documented header-filtering rule alone can expose cookies.

- Around line 143-144: Normalize read timeouts in the request flow that raises
RequestTimeoutError: handle wrapped read-timeout ConnectionErrors from both
session.request and response.content, converting only those timeouts to
RequestTimeoutError. Allow unrelated ConnectionErrors to propagate unchanged.
- Line 110: Update the `timeout` entry in the request documentation to describe
it as an inactivity limit, not a request deadline. Clarify that ongoing response
data can keep the request active beyond `request.timeout`, and distinguish this
limit from aiohttp’s session-wide total timeout.
- Line 140: Update the request call so it omits the timeout keyword when
request.timeout is None, preserving any default timeout supplied by the session
subclass; continue passing request.timeout when it has a value.

- Around line 147-148: Update the timeout translation example to recognize a
MaxRetryError whose reason is ReadTimeoutError, in addition to the direct
ReadTimeoutError wrapper, and raise RequestTimeoutError for either case.
Preserve the existing handling for other retry failures.
- Around line 146-148: Read the response body within the existing try block so
streaming read timeouts are handled by the surrounding exception handlers, then
use that captured body when constructing the result instead of reading
response.content afterward. Preserve the existing timeout error translation and
redirect behavior.
- Line 147: Update the connection-error handler’s ReadTimeoutError check to
verify error.args is nonempty before accessing error.args[0]. Preserve
timeout-specific handling when an argument is present and allow a
ConnectionError with no arguments to propagate without raising IndexError.
