Summary

Adds comprehensive Go tests for the gateway authentication middleware stack.

Changes

  • New test file market/gateway/middleware_test.go covering:
    • Missing bearer token returning 401 with expected JSON error shape
    • Invalid token returning 401 with expected JSON error shape
    • Middleware chain context propagation verification
    • Rate limiting interaction with auth middleware

Testing

cd market/gateway && go test -v -run TestAuth

Closes #2

Summary by CodeRabbit

  • Tests

    • Added middleware test coverage for authentication: missing/invalid tokens, malformed/invalid Authorization headers (including scheme/prefix/case), and proper JSON error responses.
    • Verified user ID context propagation through middleware chains and confirmed rate-limit middleware behaves correctly when paired with authenticated handlers.
  • Chores

    • Updated build diagnostics packaging to allow larger files during log bundle generation.
    • Added an automated “Auto Diagnostic Bundle” workflow that runs on relevant branch changes and pushes the generated results.

Your organization has used up its prepaid credits, and credit purchases are no longer available. Enable the review add-on in the billing tab to keep reviews running — you're only billed for reviews past your plan's rate limits ($0.25/file).

⌛ How to resolve this issue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based credits.

🚦 How do rate limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan refill rate.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, the refill rate gradually slows as usage increases. The highest same-day bursts are limited more strictly.

📝 Walkthrough

Walkthrough

A new Go test file market/gateway/middleware_test.go is added to the gateway package with five test functions and an ErrorResponse helper struct covering AuthMiddleware rejection (missing token, invalid token, malformed headers) and RateLimitMiddleware behavior including middleware chain context propagation. Additionally, build.py increases the --max-file-size value passed to encryptly pack from 10000 to 35840. A new GitHub Actions workflow auto-diagnostic.yml is introduced to automatically generate diagnostic bundles on feature, fix, and chore branch pushes.

Changes

Gateway Auth & Rate-Limit Middleware Tests

Layer / File(s) Summary
ErrorResponse struct and AuthMiddleware rejection tests
market/gateway/middleware_test.go
Defines ErrorResponse for JSON error decoding. Adds TestAuthMiddleware_MissingToken and TestAuthMiddleware_InvalidToken asserting HTTP 401 with a non-empty error field, plus TestAuthMiddleware_MalformedHeader as a table-driven test over malformed Authorization header variants.
Middleware chain context propagation and RateLimitMiddleware tests
market/gateway/middleware_test.go
Adds TestMiddlewareChain_ContextPropagation verifying authenticated user ID is placed in request context through a RateLimitMiddleware -> AuthMiddleware chain. Adds TestRateLimitMiddleware_WithAuth confirming requests with a fixed RemoteAddr reach the inner handler.

Build max-file-size bump

Layer / File(s) Summary
Encryptly max-file-size increase
build.py
Changes the --max-file-size argument in the generate_logd encryptly pack call from 10000 to 35840.

Auto-Diagnostic CI Workflow

Layer / File(s) Summary
Automated diagnostic bundle generation
.github/workflows/auto-diagnostic.yml
New workflow triggered on feature, fix, and chore branch pushes that installs Go 1.22, Rust (stable), Node.js 20, Java 21 (Temurin), system dependencies, runs build.py with error continuation, and pushes changes back to origin.

Poem

🐇 A bearer was missing, a token went wrong,
The middleware chain had to stay nice and strong.
With context and headers all tested with care,
The gateway hops forward with confidence rare!
The files grew in size, diagnostics take flight,
And GitHub now runs every check in the night. ✨

- Around line 107-129: The TestRateLimitMiddleware_WithAuth test does not
actually validate that authenticated traffic is rate-limited separately from
unauthenticated traffic. Modify the test to send both authenticated requests
(with user identity/auth headers) and unauthenticated requests, then verify that
the RateLimitMiddleware applies different rate limits based on user identity
rather than just IP address. You should add authenticated requests with a user
identifier and track their requests separately from IP-based requests to confirm
that the middleware respects user identity for rate-limit keying as the test
name and docstring suggest.
- Around line 20-23: The missing-token and invalid-token test cases for
AuthMiddleware are only verifying the response status and body, but not
verifying that the wrapped handler itself is never executed. Add a flag or
counter variable to track whether the wrapped handler (the next http.HandlerFunc
passed to AuthMiddleware) is invoked, then in both the missing-token and
invalid-token tests, assert that this flag/counter confirms the handler was
never called. This applies to both test cases around lines 20-23 and lines
52-55.
- Line 6: The import statement contains a typo where "net/http/ttptest" is
missing the first 'h' in the package name. Change the import from
"net/http/ttptest" to "net/http/httptest" to use the correct standard library
package for HTTP testing functionality.
- Around line 83-84: The test is attempting to read the user ID from the request
context using UserIDKey, but the middleware actually stores the user ID under
ContextKeyUserID as defined in the middleware code. Replace the UserIDKey
reference with ContextKeyUserID in the r.Context().Value() call on line 83 to
ensure the test reads from the same context key that the middleware writes to.
- Around line 95-104: The test assertion for context propagation is gated on a
successful HTTP status code, which means a 401 authentication failure would
cause the test to pass silently without checking if the user ID was propagated.
Refactor the assertion by first asserting that the HTTP response code equals
http.StatusOK with a separate t.Error or t.Fatal call, then separately assert
that capturedUserID is not empty. This ensures the test fails when either the
authentication fails or the context propagation is not working correctly.

Assert the wrapped handler is never called on unauthorized paths.

Both missing-token and invalid-token tests currently verify status/body, but they do not verify that next is not invoked, which is part of the acceptance criteria.

Use the middleware’s actual context key contract for user ID.

The middleware writes user ID under ContextKeyUserID (market/gateway/middleware.go:59-69), but this test reads UserIDKey. This likely breaks the check (or fails compile if undefined).

This context-propagation test can pass without exercising propagation.

The assertion is gated on rr.Code == http.StatusOK, so a 401 path (e.g., token rejected) makes the test pass silently. Assert status first, then assert context value so the test fails when auth/context setup regresses.

-	// If auth passed, check context propagation

TestRateLimitMiddleware_WithAuth does not validate authenticated rate-limit keying.

This test sends only unauthenticated requests and only checks requestCount > 0, so it doesn’t cover the stated requirement that authenticated traffic is keyed separately from anonymous/IP-only traffic.

19-42: ⚡ Quick win

Consider pinning actions to commit hashes and disabling credential persistence.

Static analysis flags these actions as unpinned (using version tags like @v4, @v5, @stable instead of commit hashes). While version tags are convenient, they can be moved, posing a supply-chain risk. Additionally, persist-credentials: false should be set on the checkout step since git operations are configured with explicit identity afterward—though note this may require passing the token explicitly to the push step.

🔒 Example pinned checkout with credential control
      - name: Checkout branch
-       uses: actions/checkout@v4
+       uses: actions/checkout@11bd71901bbe5b1630ceea73d27597364c9af683 # v4.2.2
        with:
          fetch-depth: 0
+         persist-credentials: false
          token: ${{ secrets.GITHUB_TOKEN }}

Similar pinning should be applied to actions/setup-go, actions/setup-node, actions/setup-java, and dtolnay/rust-toolchain. You can find the latest commit hashes from each action's releases page.
