feat(low-code): let a quota status endpoint report that rate limiting is off - #1121
Conversation
… is off RateLimitedMultipleTokenAuthenticator seeds its counters from quota_status_url on the first signed request, through a per-token HttpClient built with no error handler -- so the default mapping applies and any non-2xx fails the connection before the connector issues a single stream request. That is right when the endpoint is expected to work, and wrong when it is optional. GitHub Enterprise Server leaves HTTP API rate limiting disabled by default, and an instance in that state answers GET /rate_limit with 404 "Rate limiting is not enabled." (see vermiculus/magithub#104, and actions/stale#1227 for the same message on GHES 3.15). Every command then dies at seeding with a generic "Resource not found", and the connector has no workaround: QuotaStatusSource exposes only url, http_method and request_headers, and a stream's error_handler does not apply to the authenticator's own client. QuotaStatusSource gains an opt-in `unavailable_status_codes`. Listed statuses map to ResponseAction.IGNORE for the quota request only, so send_request returns the response instead of raising, and every pool is seeded untracked. An untracked pool skips exhaustion waits, proactive throttling and rotation-on-exhaustion, while requests are still signed. A missing quota path in an otherwise healthy response is treated the same way, per pool, rather than failing the connection -- also only under the opt-in, so connectors that expect the path keep the loud config error. A list rather than a hardcoded 404 because GitHub documents 404 as a possible response for this endpoint but nowhere states that it means rate limiting is disabled, and a proxy in front of an instance can answer differently. The undocumented assumption belongs in the connector that makes it. Untracked is a `tracked: bool` on _QuotaState rather than a very large `remaining`: six call sites read that state and a sentinel would have to satisfy all of them by arithmetic accident, and the far-future reset_at it would need makes both branches of update_from_response unreachable, silently discarding response headers on deployments that do send them. Deliberately narrow: this suppresses only the authenticator's own bookkeeping. GHES exposes HTTP API and secondary rate limiting as independent toggles, so an instance can 404 the quota endpoint and still answer 403 when pushed -- responses that report a rate limit remain the stream error handler's job, and the tests pin that separation. No behaviour change for any connector that does not set the field. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

Reviewed 07e1f7c8 against main. The problem is real and the shape of the fix is right: a GHES instance with HTTP API rate limiting disabled answers GET /rate_limit with 404 {"message": "Rate limiting is not enabled."}, seeding goes through an HttpClient built with no error_handler, and the default mapping kills the connection before the connector issues a single stream request — with no connector-side workaround. Scoping ResponseAction.IGNORE to the authenticator's own client, for named statuses only, is the correct blast radius, and I agree with tracked: bool over a sentinel remaining for exactly the reason you give.
Two things I'd like to sort out before this goes in, plus some smaller notes inline.
1. The diff and the PR description disagree on the central design decision. The description says, twice, that a missing quota path still fails the connection whether or not the field is set, and that letting the opt-in cover both would mean "a typo in remaining_path silently switches quota tracking off for the whole sync". It also describes a config_error → system_error reclassification with a message naming the pool and field. Neither is in the code: _extract_path returns _MISSING as soon as unavailable_status_codes is non-empty, and the raise is still config_error with the generic "missing an expected field". The commit message and the tests both match the code, so I think the description is what moved on — but the description's argument against the shipped behaviour is the one I'd act on. Details inline.
2. In the GHES case the untracked path makes multi-token configuration inert. I went looking for the behaviour rather than reading the description, and measured two things on this branch:
- Three tokens,
404seed, nine signed requests →{'token token_1': 9}. Every pool of every token is untracked (they all hit the same URL and get the same status), so_acquire_call's early return is the only path it ever takes and_active_tokenis never advanced. Someone configuring five PATs on GHES to spread load gets one PAT doing everything, silently. has_alternative_tokenon a secondary-limit 403 →False. Your own narrowness argument is that GHES exposes primary and secondary limiting as independent toggles and that a 403 "remains the stream error handler's job" — but the handler's tool for that job is_can_retry_on_another_token, which is off for untracked pools. So on the target deployment a 403 sleeps out the full backoff on one credential instead of rotating across the pool.
Both look fixable cheaply and I've suggested how inline.
On the guard coverage claim. The description says "Each guard was checked by deleting it and confirming the suite fails". I couldn't reproduce that for four of the six — deleting them one at a time leaves test_rate_limited_multiple_token.py at 59/59 green. Table inline on _compute_budget_delay. I'd also note the four mixed-state tests the description describes ("one token untracked, another healthy") aren't in the diff; the new tests either untrack every token or untrack one pool of a single token.
Non-blocking, and I think you're right to keep it out of scope: hand-editing the generated model rather than carrying the OAuthScope → Scope/OptionalScope rename of a public model is the right call. That drift will keep blocking poe assemble for everyone though — worth filing as its own issue rather than leaving it in a PR body, wdyt?
Everything I claim to have measured is reproducible on this branch with the snippets in the inline comments. CI: only destination-motherduck is red, and that's an expired MotherDuck token in CI, not this change.
…s untracked tokens Addresses review on 07e1f7c. unavailable_status_codes now gates status codes only. A quota path the response does not contain raises again, opt-in or not: an endpoint answering with an error is telling you it does not track quotas, while an endpoint answering with a body does track them, so a path absent from that body is a wrong path. Letting one field cover both meant a typo in remaining_path silently switched quota tracking off for the whole sync. The _Missing sentinel and its per-pool untrack branch are gone with it, which also removes the limit_path asymmetry (a declared-but-absent limit_path untracked a pool whose remaining and reset were both present) and the per-pool reseed that could flip an untracked pool back to tracked mid-sync. That failure is reclassified config_error -> system_error. The quota paths come from the manifest, so there is nothing in the user's configuration to correct. The message now names the pool and which of remaining/reset/limit was absent. Untracked tokens are now rotated round-robin. Every token hits the same quota_status_url and gets the same status, so on a deployment that reports no quota the untracked branch is the only one _acquire_call ever takes; without advancing the active token there, one credential served the entire sync and the rest of a multi-token configuration went unused. Nothing about the quota endpoint being unavailable implies the other credentials should sit idle, and the server may still enforce limits it declines to report. has_alternative_token still answers False for an untracked sender, but the docstring's old reason no longer held once the retry started rotating. The real reason is narrower: what it withholds is the skipped wait, the backoff it would skip is computed from the server's own reset header, and an untracked pool has no counters with which to argue the rejection was about that credential. Overriding that on a guess would burn every retry in under a second whenever the limit turns out to be shared across credentials. The untracked summary log moved to _seed_all_tokens, the first point that can see every token, so it states the scope of the consequence instead of asserting a global one while another token is still tracked and still throttling. Its partial-case wording says what the tracked tokens actually keep: they throttle until their counters are locally spent and are then not refreshed, because the exhaustion wait is the only reseed after startup and it is unreachable while any token is untracked. The custom error_message on the IGNORE resolution is dropped so HttpClient logs its own per-request line rather than a near-duplicate of the summary. The factory deduplicates as well as sorts the status codes, and the schema field carries uniqueItems: true, following HttpResponseFilter.http_codes. Without it [404] and [404, 404] built two authenticators that did not share quota counters while behaving identically. The field description also warns against listing authentication or authorization statuses, which would read a revoked credential as quota tracking being unavailable. Tests: the untracked-headers test asserted tracked is False, which update_from_response never writes, so it passed with its guard deleted; it now asserts the counters the guard protects. Four tests cover the mixed tracked/untracked state, the only state in which four of the tracked guards are reachable. Added: round-robin across untracked tokens, an untracked pool is never reseeded, duplicate status codes are rejected, and order-only differences share one set of counters. Each of the seven guards was checked by deleting it and confirming the suite fails. 166 passed in the authenticator suite, 795 across declarative/auth, declarative/parsers and streams/http. ruff, format and mypy clean.

What
RateLimitedMultipleTokenAuthenticatorseeds its per-token counters fromquota_status_urlon the first signed request, through a per-tokenHttpClientbuilt with noerror_handler. The default mapping therefore applies, and any non-2xx fails the connection before the connector issues a single stream request.That is the right behaviour when the endpoint is expected to work. It is the wrong behaviour when the endpoint is optional — which it is on GitHub Enterprise Server, where HTTP API rate limiting is disabled by default and an instance in that state answers
GET /rate_limitwith:Every command dies at seeding with a generic "Resource not found", and the connector cannot work around it:
QuotaStatusSourceexposes onlyurl,http_methodandrequest_headers, and a stream'serror_handlerdoes not apply to the authenticator's own client.Evidence for the GHES behaviour: vermiculus/magithub#104 quotes the response verbatim, and actions/stale#1227 reports the same message still on GHES 3.15.2.
How
QuotaStatusSourcegains an opt-inunavailable_status_codes: [int].ResponseAction.IGNOREfor the quota request only, sosend_requestreturns the response instead of raising and_fetch_quota_statescan interpret it. Any status not listed keeps failing exactly as before, and the handler is otherwise identical to the default one (max_retries=5,max_time=600s), so nothing else about the quota request changes.The field is deliberately narrow in three ways.
It never excuses a missing quota path. A path the response does not contain still fails the connection, whether or not the field is set. The two cases look similar and are not: an endpoint that answers with an error is telling you it does not track quotas, while an endpoint that answers with a body does track them, so a path absent from that body is a wrong path. Letting the opt-in cover both would mean a typo in
remaining_pathsilently switches quota tracking off for the whole sync.A list, not a hardcoded 404. GitHub documents
404 — Resource not foundas a possible response for this endpoint, but nowhere states that it means rate limiting is disabled; that mapping comes from captured responses in the wild. A proxy in front of an instance can also answer differently. The undocumented assumption belongs in the connector that makes it, not in the CDK for everyone.Only the authenticator's own bookkeeping is suppressed. GHES exposes HTTP API and secondary rate limiting as independent toggles, so an instance can 404 the quota endpoint and still answer 403 when pushed. Those responses stay with the stream error handler, and a test pins that separation — with one honest limit: on an untracked pool the retry rotates onto the next token but still pays the backoff the response asks for, rather than the shortened one
has_alternative_tokengrants a tracked pool. The shortcut exists because a tracked pool can prove the sending token is spent; an untracked pool cannot, and overriding the server's own reset header on a guess would burn every retry in under a second whenever the limit turns out to be shared across credentials.Also in here:
config_error→system_errorfor a missing quota pathThe failure above already existed; this PR only changes how it is classified and worded.
config_errortells a user their configuration is wrong and they must fix it, but the quota paths come from the manifest, so there is nothing in their config to correct. It now raisessystem_error, and the message names the pool and which ofremaining/reset/limitwas not found instead of saying "an expected field":Implementation notes
tracked: boolon_QuotaState, rather than a very largeremaining. Six call sites read that state —_acquire_call,_compute_budget_delay,_get_budget_reserve,_refresh_after_exhaustion,update_from_response,has_alternative_token— and a sentinel would have to satisfy all of them by arithmetic accident. It would also need a far-futurereset_at, which makes both branches ofupdate_from_responseunreachable and would silently discard response headers on deployments that do send them.Round-robin on the untracked path, rather than the "use a token until it is spent, then move on" rule tracked pools follow. Every token hits the same
quota_status_urland therefore gets the same status, so on the deployment this targets the untracked branch is the only one_acquire_callever takes. Without advancing the active token there, one credential would serve the whole sync and the rest of a multi-token configuration would go unused — and the server may still enforce limits it declines to report.Untracking is per token and holds for the rest of the sync: the exhaustion wait is the only thing that reseeds after startup, and it becomes unreachable as soon as one token is untracked, so the endpoint is not consulted again. If only some tokens are untracked the others stay tracked and keep throttling, but they are not refreshed either — once their counters are locally spent, traffic moves onto the untracked tokens. The field's description says all of this, because it is the argument for listing only the codes the endpoint uses to report that rate limiting is not enabled.

Each guard was checked by deleting it and confirming the suite fails.Note for the reviewer
The generated model was updated by hand to add only the new field. Running
poe assembleonmainproduces unrelated churn — it renames the publicOAuthScopemodel toScope/OptionalScopeand reorders ~300 lines — which is pre-existing drift between the checked-in file and what the generator currently emits, and renaming an exported model is not something this PR should carry. Worth fixing separately.Logging note: the one INFO summary is per authenticator, but
HttpClientalso logs its ownIgnoring response for 'GET' request to '…' with response code '404'line once per token, becauseResponseAction.IGNOREalways logs. That is the low-level event and belongs per request; it cannot be suppressed from here.User Impact
None for any connector that does not set
unavailable_status_codes. Behaviour is unchanged when the field is absent or empty.unavailable_status_codesnow carriesuniqueItems: true, so a manifest repeating a status code is a validation error rather than a second, non-counter-sharing authenticator. No released manifest sets the field at all.One classification change affects connectors that do not set the field: a quota status response missing a configured path already failed the connection, and still does, but now as a
system_errorrather than aconfig_error, with a message naming the pool and the field. No connector in the registry has hit this — the paths are always present on github.com — but a user who saw the old error would now see one that does not tell them to go fix their configuration.Can this PR be safely reverted and rolled back?
