Inline comments:
In `@gears/system/oagw/oagw/src/api/rest/handlers/proxy.rs`:
- Around line 107-115: Update the preflight branch to pass requested_method,
rather than method.as_str(), to resolve_proxy_target so CORS resolution uses the
requested GET/POST method and preserves the configured route policy. Keep the
existing fallback and preflight_response flow unchanged.
- Around line 227-237: Update proxy_handler’s client IP derivation used by
ProxyRequest and DataPlaneService::rate_key so RateScope::Ip cannot be
controlled by arbitrary request headers: prefer trusted connection metadata, or
only honor x-forwarded-for and x-real-ip after validating the request originated
from a configured trusted proxy.
In `@gears/system/oagw/oagw/src/api/rest/tests.rs`:
- Line 658: Update the WebSocket receive in the test around ws.next() to use
tokio::time::timeout with a finite duration, then unwrap the timeout result and
received message so a missing forwarded message fails promptly instead of
hanging.
In `@gears/system/oagw/oagw/src/config.rs`:
- Around line 124-125: Update the max_body_bytes validation in the configuration
validator to reject values greater than the documented 100 MiB hard limit, while
retaining the existing rejection for zero; use the existing limit definition
near the configuration defaults instead of duplicating the numeric bound, and
ensure only validated values reach data-plane construction.
In `@gears/system/oagw/oagw/src/domain/dto.rs`:
- Around line 512-517: Update MatchConfig deserialization to require exactly one
of the http and grpc fields, rejecting objects with neither or both instead of
silently selecting an untagged variant; preserve the existing HttpMatch and
GrpcMatch payload parsing, and add a regression test covering an object
containing both protocols.
- Around line 78-79: Update Endpoint deserialization so an omitted port uses the
parsed scheme’s default_port() rather than the static
Endpoint::default_port_field value, preserving explicit ports. Add a regression
test covering an HTTP endpoint without a port and verifying port 80.
In `@gears/system/oagw/oagw/src/domain/error.rs`:
- Around line 275-280: Add and provision distinct generic-resource-not-found and
internal-error GTS problem types, then update the error-to-ProblemInfo mapping
so NotFound uses the generic resource type, Internal uses the internal-error
type, and RouteNotFound retains ERROR_ROUTE_NOT_FOUND; update the corresponding
mapping near the Internal variant as well.
In `@gears/system/oagw/oagw/src/domain/plugin/mod.rs`:
- Around line 77-102: Update the GuardDecision::Reject to PluginError::Reject
conversion so supported rejection statuses, including 403, preserve their
original HTTP status in the resulting DomainError. Do not route every unhandled
status through DomainError::Validation; if the domain model permits only a fixed
status set, validate unsupported values at the plugin boundary and reject them
explicitly.
In `@gears/system/oagw/oagw/src/domain/services/alias.rs`:
- Around line 128-130: Update the multi-endpoint alias derivation around
is_standard_port to validate that every endpoint has the same scheme and port as
endpoints[0]. Return AliasDecision::ExplicitRequired when any endpoint differs;
only derive the alias and apply standard-port handling after uniformity is
confirmed.
- Around line 246-247: Update validate_endpoint_url to compare the parsed URL
scheme with the caller-provided EndpointScheme and return a validation error on
mismatch before calling port_or_known_default(). Add tests covering both HTTPS
configured with an HTTP URL and HTTP configured with an HTTPS URL.
In `@gears/system/oagw/oagw/src/domain/services/data_plane.rs`:
- Line 206: Update the HTTP forwarding error message near the endpoint scheme
validation to use the grammatically correct “is not supported” wording, matching
the existing WebSocket error message style.
- Around line 455-459: In the round-robin arm of select_endpoint, guard against
an empty endpoint list before computing fetch_add modulo eps.len(). Return
DomainError::LinkUnavailable for empty eps, while preserving the existing
round-robin selection for non-empty lists.
In `@gears/system/oagw/oagw/src/domain/services/management.rs`:
- Line 315: Update the update_route validation flow to pass the target route ID
explicitly into validate_route, and have its uniqueness check exclude the route
matching that target ID rather than input.id. Preserve normal conflict detection
against all other routes, including when the request body omits id.
In `@gears/system/oagw/oagw/src/infra/plugin/apikey_auth.rs`:
- Line 85: Update the query-pair construction in the API-key authentication flow
to encode param_name with the same form encoder used by encode_query_value for
key before inserting it into the query string; preserve the existing value
encoding and parameter formatting.
- Line 59: Update the validation around the header and param targets in the
API-key binding configuration to require exactly one target: reject both targets
and reject neither target, while preserving the existing single-target injection
behavior in the apikey authentication flow.
In `@gears/system/oagw/oagw/src/infra/proxy/forwarder.rs`:
- Around line 57-58: Update the client construction in Forwarder to support
HTTPS URIs when EndpointScheme::Https is configured, using a TLS-capable
connector with HttpConnector as its underlying transport; otherwise explicitly
validate and reject HTTPS configuration with a clear configuration error before
forwarding. Preserve existing HTTP forwarding behavior.
In `@gears/system/oagw/oagw/src/infra/proxy/rate_limiter.rs`:
- Around line 124-125: In the allowed branch of the rate-limiter flow, move the
remaining-token and reset-time calculations using bucket.tokens and
remaining_refill_epoch(bucket) to after the cost subtraction. Ensure successful
responses report the post-consumption X-RateLimit-Remaining and
X-RateLimit-Reset values.
- Around line 98-102: Update the bucket-management logic around the buckets map
and MAX_BUCKETS so inserting a new key cannot leave the map above the hard
limit. Before adding a bucket when the limit is reached, evict at least one
existing bucket using an oldest-entry policy or bounded-cache behavior, while
preserving the current idle-bucket retention cleanup.
In `@gears/system/oagw/oagw/src/infra/storage/mod.rs`:
- Around line 145-147: Update the conflict scan using routes_conflict so it also
filters existing routes by the same upstream_id as the new route, while
retaining the tenant, path, and method conflict checks and documented uniqueness
behavior.
In `@gears/system/oagw/oagw/src/infra/type_provisioning.rs`:
- Line 154: Update the GTS catalog declaration around gts_instance_raw! to
remove the unsupported wt, grpc, basic, and bearer entries, unless complete
scheme validation, forwarding, and plugin implementations are added; ensure the
catalog advertises only values supported by the upstream policy and
AuthPluginRegistry::with_builtins.

Resolve the target with the requested CORS method.
The request method is OPTIONS in this branch. resolve_proxy_target matches routes using that method, so a normal GET or POST route without an OPTIONS match fails resolution. The handler then returns the wildcard fallback instead of the configured CORS policy.
Pass requested_method to resolve_proxy_target.

Use trusted connection metadata for RateScope::Ip.
proxy_handler passes client_ip(&headers) into ProxyRequest, and DataPlaneService::rate_key uses it directly for RateScope::Ip. If the gateway does not sanitize these headers, a caller can select arbitrary rate-limit buckets. Derive the address from connection metadata, or validate forwarding headers from trusted proxies.

Enforce the documented 100 MiB body limit.
Line 124 rejects only zero. A value above 100 * 1024 * 1024 passes validation although Lines 75-76 define 100 MiB as a hard limit. The data plane consumes this value for response-body acceptance. Large configured values can remove the memory safety bound.

Derive the default port from scheme.
EndpointScheme::default_port() defines port 80 for HTTP, but the serde default always assigns 443. An HTTP endpoint without port can therefore produce host:443 in alias and proxy authority handling. Apply scheme.default_port() when port is absent and add a regression test.

Endpoint deserialization so an omitted port uses the parsed scheme’s
default_port() rather than the static Endpoint::default_port_field value,
preserving explicit ports. Add a regression test covering an HTTP endpoint

hyper-util legacy HttpConnector documentation HTTPS scheme only http
💡 Result:
In the hyper-util crate, the HttpConnector is designed specifically for the http scheme [1][2]. By default, HttpConnector enforces that all URIs provided to it must use the http scheme [1][2]. This behavior is controlled by the enforce_http method, which is enabled by default [1][2]. If you attempt to use it with an https URI while this enforcement is active, it will reject the request with an error [3][2]. If your application requires support for HTTPS, you should not use a plain HttpConnector [3]. Instead, you should use an appropriate HTTPS-capable connector—such as those provided by crates like hyper-rustls—which often wrap an HttpConnector [3]. When wrapping an HttpConnector inside a TLS-capable connector, it is common practice to call enforce_http(false) on the HttpConnector instance to prevent it from prematurely rejecting https requests before the TLS layer can process them [3][4].

Add TLS support for HTTPS endpoints.
When EndpointScheme::Https is selected, DataPlaneService::endpoint_http_url creates an https:// URI. Forwarder passes that URI to HttpConnector, which rejects non-http schemes. DataPlaneService::map_forward_error then returns LinkUnavailable. Add a TLS connector, or reject HTTPS endpoints with an explicit configuration error.

Enforce a hard bound on tracked buckets.
This eviction only removes buckets that have been idle for more than one window. A continuous stream of distinct keys keeps each new bucket inside that window. The map can then grow indefinitely beyond MAX_BUCKETS.
Evict an oldest bucket, or use a bounded cache, before inserting a new key when the limit is reached.

Calculate allowed-response headers after token consumption.
Lines 124-125 read the balance before Line 128 subtracts cost. A bucket with one token reports X-RateLimit-Remaining: 1 on its allowed final request, although the next request is rejected. X-RateLimit-Reset is also too early.

Scope route conflict detection by upstream_id.
routes_conflict does not compare upstream_id. This tenant-only scan rejects equal paths and methods on different upstreams. That contradicts the documented (upstream_id, path, method) uniqueness contract.
Proposed fix
- .filter(|e| e.value().tenant_id == Some(tenant_id))
+ .filter(|e| {
+ e.value().tenant_id == Some(tenant_id)
+ && e.value().upstream_id == route.upstream_id
