📝 WalkthroughWalkthroughThe PR adds a complete OAGW gear with in-process management state, tenant-scoped CRUD APIs, hierarchical configuration resolution, HTTP and streaming proxying, built-in plugins, rate limiting, standardized errors, route registration, and integration tests. ChangesOAGW gateway
Priority: ➖ Normal Estimated code review effort: 5 (Critical) | ~120 minutes Merge Risk: 🟠 High · up to This change introduces a new outbound API gateway. Several issues in the proxy path could let callers exhaust gateway memory or CPU, cause requests to hang or fail with misleading timeouts, forward protected HTTP framing headers to upstreams, and evade rate limits by rotating a client-supplied header. Requests arriving without an authenticated context are collapsed into a single shared tenant, the documented SSRF protection toggle currently has no effect, an in-use plugin can be deleted, and deleting an upstream can leave routes pointing at it. Management list filtering also rejects valid filters on names containing spaces. These should be addressed before the gateway handles real traffic. 🚥 Pre-merge checks | ✅ 3 | ❌ 2❌ Failed checks (1 warning, 1 inconclusive)

merge_query_overridesrewrites the whole query only when an override exists.With no overrides the original query string passes through byte for byte. With at least one override every inbound parameter is parsed and re-serialized. The two paths are not equivalent for all inputs. A valueless parameter such as
?flagbecomesflag=, and the override parameters always move to the end of the query.The result is that enabling api-key query placement silently changes the query an upstream receives for unrelated parameters. Preserve the original parameter text when a name is not overridden, or apply the same normalization on both paths so the behavior does not depend on the override set.

Select the route before merging route-scoped fields.
Line 118 merges Route fields before Line 119 selects the matching route. rate_limit and plugins are route-scoped, so the merge has no unique route input. This also conflicts with the merge algorithm input at Lines 169-171. Select the route after alias lookup and before the merge, then cache that resolved plan.

Define one private auth rule.
Line 180 retains the current ancestor value for private, but the acceptance criterion at Line 434 requires a descendant configuration not to surface ancestor auth. A resolver and its tests cannot satisfy both rules. Choose the intended inheritance behavior and align the algorithm, definitions of done, and acceptance criteria.

Do not use the raw x-forwarded-for header as the rate-limit identity.
client_ip_of uses the caller-controlled first token as the ip-scope bucket value. OagwConfig has no trusted-proxy policy, and the handler does not use the connection peer address. A caller can rotate this header to avoid sharing a rate-limit bucket. Derive the address from the connection peer, or add and enforce a trusted-proxy configuration.

Reject endpoint pools with divergent effective ports.
crate::domain::validate::validate_semantics does not compare endpoint ports. Therefore, a pool containing 443 and 8443 reaches apply_port_suffix through resolve_create_alias or resolve_replace_alias. Since apply_port_suffix reads only endpoints.first(), it derives vendor.com and drops the second endpoint's :8443. Validate effective ports after applying scheme defaults and reject divergent pools before alias construction.

Prevent deletion of plugins referenced by UUID
PluginItem accepts bare UUIDs and plugin_validate::parse_plugin_request validates plugin definitions only. Upstream and route create/replace paths store request.plugins without normalization. Therefore, plugin_references misses UUID bindings, and delete_plugin can remove an in-use plugin.
Normalize custom bindings to gts_plugin_id(...) before persistence, or match both canonical GTS references and UUIDs.

docs.rs axum WebSocketUpgrade protocols method selected Sec-WebSocket-Protocol axum 0.8
💡 Result:
In axum 0.8, the WebSocketUpgrade extractor provides several methods to manage the Sec-WebSocket-Protocol header and subprotocol negotiation [1][2]. The protocols method is used to set the server's preferred subprotocols [1][3]. When called, it examines the Sec-WebSocket-Protocol header sent by the client [1][3]. If any of the provided server protocols match a protocol requested by the client, the server selects the first matching protocol (following the order of preference defined in the server's list) and includes it in the Sec-WebSocket-Protocol header of the upgrade response [1][2]. Additional methods for managing subprotocols include: - requested_protocols: Returns an iterator yielding the subprotocols requested by the client in the Sec-WebSocket-Protocol header [1][4]. - set_selected_protocol: Allows for manual selection of a subprotocol [2][3]. If both protocols and set_selected_protocol are called, the latter call takes effect [2]. - selected_protocol: Returns an Option<&HeaderValue> indicating the currently selected subprotocol, if one has been set [1][2]. The selection logic ensures that the chosen protocol is correctly echoed back in the WebSocket upgrade response [2][5]. Recent updates in the axum 0.8.x series have improved how these protocols are handled, including ensuring compatibility with HTTP/2 upgrade requests [6][7][4].

Preserve the upstream-selected WebSocket subprotocol.
When the upstream response contains Sec-WebSocket-Protocol, negotiate_upstream discards it and returns only WsStream. The handler then completes WebSocketUpgrade without calling protocols, so Axum omits the selected subprotocol from the client-facing 101 response. Return the protocol with the stream and pass it to WebSocketUpgrade::protocols.

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win
$filter rejects any quoted value that contains a space.
parse_filter tokenizes with split_whitespace and then requires exactly three tokens. Line 167 strips quotes from the value, so quoted values are an intended input shape. The two rules contradict each other: $filter=name eq 'my plugin' produces four tokens and returns 400 with "expected a single 'field eq value' clause".
PLUGIN_ALLOWED_FIELDS includes name, and UPSTREAM_ALLOWED_FIELDS includes alias and tags. A plugin name is a free-form string, so a space in it is ordinary.
Line 167 also uses trim_matches('\''), which strips every leading and trailing quote instead of one pair. A value that legitimately ends in ' loses that character.
Split on the first two whitespace runs and keep the remainder as the value, then strip one quote pair.

🚀 Performance & Scalability | 🟠 Major | 🏗️ Heavy lift
The eviction scan is O(n) on the request thread and re-runs for every new key.
evict_least_recently_used_if_over_capacity calls min_by_key across the whole DashMap. admit calls it whenever is_new_key is true. Once the map is at BUCKET_CAPACITY, every request carrying a previously unseen key is a new key, so every one of those requests scans up to 10,001 entries inline.
The module doc at lines 118-122 names the exact trigger: an ip-scope value taken from an unvalidated X-Forwarded-For first hop, supplied fresh on each request. The capacity bound stops memory exhaustion. It does not stop CPU exhaustion. An attacker that rotates the header value forces a full-map scan per request on the proxy hot path, which turns the bounded map into a CPU-exhaustion vector instead.
Use an eviction structure with better than linear cost, or amortize the scan. A simple amortization: evict a batch once the map exceeds the cap by a margin, so the scan runs once per batch rather than once per request.
⚡ Proposed amortization
const BUCKET_CAPACITY: usize = 10_000;

+/// How far the map may exceed [`BUCKET_CAPACITY`] before one eviction pass
+/// runs. Amortizes the O(n) least-recently-used scan across `EVICTION_BATCH`

}Note that the_bucket_map_stops_growing_past_its_capacity_under_many_distinct_keys asserts len() <= BUCKET_CAPACITY. Relax that bound to BUCKET_CAPACITY + EVICTION_BATCH if you adopt the batch.

Hold tenant.write_guard across the upstream removal and the route cascade.
delete_upstream mutates tenant.upstreams and tenant.routes without taking tenant.write_guard. create_route holds that guard across its upstreams.contains_key(&upstream_id) check (line 393) and its routes.insert (line 438). Because delete_upstream does not take the guard, the two can interleave:
create_routeacquires the guard and passes thecontains_keycheck for upstreamU.delete_upstreamremovesUand runsroutes.retain(...), which sees no new route yet.create_routeinserts the route bound toU.
The store then holds a route referencing a deleted upstream_id. That breaks cpt-cf-oagw-dod-route-cascade-delete, which requires no orphaned route referencing a deleted upstream_id (gears/system/oagw/docs/features/route-management.md, line 488). The orphaned route is never cascade-removed afterward, and proxy resolution can later match a route whose upstream no longer exists.
Take the same per-tenant guard here, as create_route and delete_plugin do.
