📝 WalkthroughWalkthroughThe change adds the OAGW gear with configuration, domain models, validation, storage, plugins, rate limiting, CORS, metrics, auditing, proxying, REST management APIs, and integration tests. ChangesOAGW gateway
Estimated code review effort: 5 (Critical) | ~120 minutes Merge Risk: 🟠 High · up to The new gateway implementation still contains high-impact correctness, availability, and security issues: queued rate-limited requests can become permanently rejected, concurrent updates can restore deleted resources or stale targets, malformed security configuration can disable enforcement, and some request paths can panic. The PR is not safe to merge until these issues are fixed or explicitly accepted by the owners. Sequence Diagram(s)sequenceDiagram

Inline comments:
In `@gears/system/oagw/oagw/src/api/rest/error_layer.rs`:
- Around line 152-155: In the Err(error) branch that returns
Response::from_parts with Body::empty(), remove the existing Content-Length
header from parts before constructing the response, while preserving the warning
and empty-body behavior.
In `@gears/system/oagw/oagw/src/api/rest/extractors_tests.rs`:
- Around line 115-121: Update the padding calculation in the boundary payload
test so the JSON wrapper overhead and repeated alias bytes produce a body
exactly equal to MAX_BODY_BYTES, using the correct 12-byte overhead. Keep the
existing payload structure and assertions unchanged.
In `@gears/system/oagw/oagw/src/api/rest/routes.rs`:
- Around line 289-299: Declare the required path parameter alias on the
oagw.proxy OperationBuilder for /oagw/v1/proxy/{alias}, matching the parameter
declaration used by the sibling operation, while leaving the runtime handler and
route behavior unchanged.
In `@gears/system/oagw/oagw/src/domain/audit.rs`:
- Around line 280-287: Update AuditEvent::level to consider both outcome and
status: classify 401/403 as ERROR only for gateway outcomes, while upstream 4xx
responses follow the documented INFO level; preserve WARN for 429 and ERROR for
statuses 500 and above.
In `@gears/system/oagw/oagw/src/domain/cors.rs`:
- Around line 380-382: Update evaluate_preflight so the
Access-Control-Allow-Credentials header is emitted only when both
config.allow_credentials and granted are true; preserve the existing header
behavior for allowed origins while omitting it for disallowed origins.
- Around line 536-537: Update the header conversion logic around
HeaderValue::from_str to return an Option and omit the CORS header when parsing
fails, rather than falling back to the wildcard value. Ensure the callers
handling allow_headers and expose_headers propagate the None result while
preserving valid header values.
In `@gears/system/oagw/oagw/src/domain/metrics.rs`:
- Around line 205-212: Update the histogram bucket indexing around
DURATION_BUCKETS and the counts storage so observations above the final bound
use a dedicated overflow slot rather than the last finite bucket. Preserve
render’s existing cumulative finite-bucket logic and +Inf state.count handling,
and add a test recording a value above 10.0 that verifies the le="10" count
remains below the +Inf count.
- Around line 571-576: Update the status classification match used by
record_request/status_class to map the 1xx status class to STATUS_1XX, while
preserving the existing 2xx, 3xx, 4xx, and fallback mappings.
- Around line 275-280: Update the Prometheus label construction in
record_request, record_error, and record_duration to use underscore-based label
names instead of dotted names, while preserving the existing dotted names in
OpenTelemetry attributes.
In `@gears/system/oagw/oagw/src/domain/plugin.rs`:
- Around line 570-576: Update the from_error constructor so ErrorContext.headers
includes a Retry-After header when retry_after is present, while preserving the
existing retry_after field and empty-header behavior when absent. Use the
existing header construction conventions and keep the documented headers
contract accurate.
In `@gears/system/oagw/oagw/src/domain/rate_limit.rs`:
- Around line 383-384: Update TokenBucket::time_to_tokens in the projected <
target branch to replace the panicking Duration::from_secs_f64 conversion with
Duration::try_from_secs_f64, falling back to Duration::MAX when conversion
exceeds the supported range.
- Around line 482-484: Update SlidingWindow::time_to_tokens to compute current
consumption by pruning or otherwise excluding expired hits at the supplied now
instant before applying the capacity check and calculating wait time; do not
rely on the stale self.consumed field. Preserve zero delay when the current
consumption plus cost fits within capacity, and ensure idle windows no longer
return Duration::MAX.
In `@gears/system/oagw/oagw/src/infra/plugin/required_headers_tests.rs`:
- Around line 110-120: The RequiredHeadersGuardPlugin::new constructor currently
converts malformed payloads and values into empty configuration; change it to
return Result<Self, OagwError>, using OagwError::validation to reject non-object
payloads and non-string header values. Update PluginRegistry::with_builtins and
build_chain to propagate the constructor error instead of wrapping it as
unconditional success, while retaining no-op behavior for absent or empty
configuration, and revise the affected tests to assert validation failures.
In `@gears/system/oagw/oagw/src/infra/storage.rs`:
- Around line 313-315: Update delete_upstream to acquire upstream_write in
addition to its existing route_write lock before removing the upstream, matching
the synchronization used by upsert_upstream and preventing concurrent replace
operations from resurrecting the record.
- Around line 118-127: Update TypedCache methods put, remove, remove_prefix, and
clear to perform every map mutation through ArcSwap::rcu, including the
capacity-replacement branch in put. Preserve each method’s existing semantics
while computing the new map from the current value supplied to the RCU closure,
so concurrent invalidations cannot be overwritten by stale snapshots.

Remove Content-Length when the body is dropped.
This path reuses the original parts but replaces the body with Body::empty(). If the handler set Content-Length, the response then declares a length it does not send. Drop the header on this path so the response stays self-consistent.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
The body is 8 bytes below the cap, so the inclusive boundary is untested.
The payload is {"alias":" (10 bytes) + padding + "} (2 bytes). With padding = MAX_BODY_BYTES - 20, the total is MAX_BODY_BYTES - 8. An off-by-one at exactly MAX_BODY_BYTES would still pass this test. Use 12 bytes of overhead so the body length equals the cap.

Declare the alias path parameter for /oagw/v1/proxy/{alias}.
The path template contains {alias}, but the operation declares no path parameter. The sibling operation at Line 318 declares it. An OpenAPI path parameter that appears in the template must be declared, so strict validators and generated clients reject or drop this operation. The runtime route is unaffected.

level() ignores outcome, so upstream 4xx answers log at ERROR.
The documented table (Lines 269-278) assigns INFO to an upstream outcome with a 4xx status, and ERROR to 401/403 only for the gateway outcome. The match arm on Line 282 keys on the status alone. An upstream that answers 401 or 403 is therefore recorded at ERROR, which turns normal upstream authorization rejections into error-level audit lines.

time_to_tokens reads a stale consumed, which permanently wedges a queued sliding window.
time_to_tokens compares self.consumed + cost against self.capacity, but it never prunes. self.consumed is only updated by prune, and prune runs only inside try_acquire and release.
SlidingWindow::evaluate calls time_to_tokens before try_acquire in the Queue branch (Line 1066). After an idle period longer than the window, the trace is:
self.consumedstill holds the expired hits, soself.consumed + cost > self.capacityis true and the function does not returnDuration::ZERO.- The loop skips every hit with
continue, because each one is outside the window, soaccruedstays0.0. - The loop ends and the function returns
Duration::MAX.
evaluate then takes the wait > QUEUE_MAX_WAIT branch and answers 429 with retry_after_seconds(Duration::MAX), which is u32::MAX seconds. That branch never calls try_acquire, so nothing prunes and self.consumed stays stale. Every following request for that key repeats the same rejection. The key stays rejected until the registry evicts it or the configuration changes.
Concrete trigger: algorithm: sliding_window, strategy: queue, capacity 2, window 1s; fill the window, idle 10s, then send one request.
The Reject strategy is not affected, because it calls try_acquire first and that prunes.
Compute the consumption at now instead of reading the stale field.

arc-swap ArcSwap rcu signature retry semantics compare_and_swap
💡 Result:
In the arc-swap crate, rcu and compare_and_swap serve different purposes regarding atomicity and retry logic [1][2]. rcu (Read-Copy-Update) The rcu method is designed for atomic updates where the new value depends on the current value [1]. It accepts a closure that receives the current value and returns a new value [2][3]. If another thread modifies the ArcSwap concurrently between the time the closure reads the value and the time it attempts to store the result, the operation automatically retries [1][3]. Because the closure may be executed multiple times during these retries, it is recommended to perform expensive computations outside of the rcu closure, keeping the closure body restricted to inexpensive cloning and update operations [1][2]. compare_and_swap The compare_and_swap method provides a low-level, conditional atomic update [1][2]. It compares the current stored Arc with a provided current value (using pointer-based comparison) and, if they match, replaces it with a new value [1]. This method does not perform automatic retries; if the comparison fails (i.e., the value changed concurrently), the swap does not happen, and the method simply returns the current (unchanged) value [1][2]. Unlike rcu, which manages the retry loop for you, compare_and_swap requires the caller to implement their own loop if they wish to retry the operation until success [1]. Summary of Semantics - rcu: High-level abstraction that automatically retries the update operation upon detecting concurrent modifications [1][3]. Best for complex updates [3]. - compare_and_swap: Low-level atomic primitive that performs a single check-and-set attempt [1]. Returns the actual value, allowing the caller to verify if the swap succeeded and manually decide whether to retry [1][2].

arc-swap 1.9.1 ArcSwap rcu docs.rs signature
💡 Result:
In the arc-swap crate (version 1.9.1), the rcu method is defined on the ArcSwapAny struct [1][2]. Since ArcSwap is a type alias for ArcSwapAny<Arc<T>>, it inherits this method [3][4]. The signature for the rcu method is as follows [1][5]: pub fn rcu<R, F>(&self, mut f: F) -> T where F: FnMut(&T) -> R, R: Into, S: CaS, In this signature: - T represents the inner type stored (e.g., Arc for ArcSwap) [1][4]. - F is a closure that takes a reference to the currently stored value and returns a new value [1]. - R is the return type of the closure, which must be convertible into the stored type (via Into) [1]. - S refers to the strategy used for the atomic swap (e.g., Compare-and-Swap) [1]. This method performs a Read-Copy-Update operation: it loads the current value, applies the provided closure to produce a new value, and attempts to store it back atomically [1]. If the value was updated by another thread in the interim, the operation retries [1]. Top results: [3][1][5]

delete_upstream does not hold upstream_write, so a concurrent replace can resurrect it.
upsert_upstream serializes on upstream_write (Line 262). delete_upstream serializes on route_write only. The two therefore run concurrently on the same upstreams map. A replace_upstream can pass its require_existing check, a concurrent delete_upstream can remove the record and cascade its routes, and the replace insert (Line 286) then re-publishes the upstream. The DELETE reports success while the upstream stays in the registry, now without the routes that were cascaded.
Take both locks in delete_upstream. No other path takes both, so this ordering adds no deadlock.
