Preserve trusted forwarding metadata or document the reset policy.
Rewrite removes X-Forwarded-* headers before SetXForwarded() derives values from r.In.RemoteAddr, r.In.Host, and r.In.TLS. A request from an upstream proxy can therefore reach the backend without its original forwarding chain. If that proxy is trusted, copy its forwarding values before SetXForwarded() and add a regression test.

ServeHTTP forwards the incoming request, including Authorization and Cookie headers, after setting r.URL.Scheme = url.Scheme.

actions/setup-go documentation go-version partial version check-latest latest matching patch
💡 Result:
In the actions/setup-go GitHub Action, version resolution and the impact of the check-latest input depend on the format of the version specified [1][2][3]. Version Input Formats and check-latest When you provide a version in major.minor format (e.g., '1.25'), setting check-latest: true instructs the action to resolve and install the latest available patch version for that minor release [4][3]. If you instead provide an exact patch version (e.g., '1.25.4'), the action treats it as a strict pin and will install that specific version, regardless of whether check-latest is set to true [3]. Resolution Logic When check-latest is true, the action verifies if the locally cached version is the most up-to-date available according to the version manifest [2][4]. If a newer version exists, it downloads the updated version instead of using the cache [2][5]. When set to false (the default), the action prefers any version already in the runner's tool cache that satisfies the specified version range [1][2]. Managing go-version-file For versions sourced from a file (like go.mod) via go-version-file, the action provides a specific input called go-version-file-behavior to control patch handling [6]. Setting this to latest-patch will widen an exact version from the file (e.g., '1.22.0') into a semantic version range (e.g., ~1.22.0), ensuring the action resolves the newest available patch release of that minor version [6]. This option effectively implies check-latest behavior [6]. Summary of Key Behaviors 1. Major.minor inputs (e.g., '1.25') with check-latest: true: Automatically resolves to the latest patch [4][3]. 2. Exact patch inputs (e.g., '1.25.4'): Bypasses check-latest logic and installs the exact version specified [3]. 3. go-version-file-behavior: 'latest-patch': An alternative way to ensure you receive the latest patch release when reading versions from files like go.mod [6].

- 6: GitHub pull request 785 in actions/setup-go (link omitted to avoid creating a cross-reference)
Pin Go to 1.26.8 in all four workflows.
actions/setup-go@v6 resolves go-version: '1.26' with check-latest: true to a moving patch release. This can diverge from the repository's declared go 1.26.8. Use go-version: '1.26.8' in .github/workflows/check.yaml, .github/workflows/pd-docker-image.yaml, .github/workflows/pd-tests.yaml, and .github/workflows/tso-function-test.yaml.

In @.github/workflows/check.yaml at line 15, Pin the Go version to 1.26.8 in the
setup-go configuration across .github/workflows/check.yaml:15-15,
.github/workflows/pd-docker-image.yaml:22-22,
.github/workflows/pd-tests.yaml:58-58, and
.github/workflows/tso-function-test.yaml:30-30, replacing the moving 1.26
specification at each site.

unprivileged user, grant it access to /pd-server as needed, and declare USER so
the application runs without root privileges. Keep the builder stage unchanged.

official Docker Hub golang 1.26.8-alpine image tag
💡 Result:
The official Docker Hub golang image supports the tag 1.26.8-alpine [1][2]. For the Go 1.26.8 release, the following Alpine-based tags are available within the official golang repository: - 1.26.8-alpine3.24 [1][2] - 1.26.8-alpine3.23 [1][2] - 1.26.8-alpine (this tag is typically an alias for one of the specific Alpine version tags, such as 1.26.8-alpine3.24) [1][2] These tags are maintained as part of the official library/golang repository on Docker Hub [3][1]. Note that Go 1.26.8 was released on September 1, 2026 [4].

Pin the builder image to Go 1.26.8.
golang:1.26-alpine can select a later Go patch release. Use the available official tag golang:1.26.8-alpine or pin the image by digest.

In `@Dockerfile` at line 1, Update the Dockerfile builder image reference in the
FROM instruction to use the exact official Go 1.26.8 Alpine tag, or pin the
existing builder image by digest instead of using the floating
golang:1.26-alpine tag.

Shall we fix them instead of ignoring them?

Addressed this G602 finding in 5d88bfc by appending into the reused, preallocated batch slice and removing the suppression. The queue-length snapshot stays at the same point, so batch size and request order are preserved. Capacity remains maxMergeRequests+2, which covers the first request plus a full channel; append therefore does not grow the backing array. The existing tsoutil tests pass with race/deadlock enabled, and make check passes with golangci-lint v2.13.2.
Append requests to the reused batch buffer to avoid the G602 false positive. Preserve the queue-length snapshot, request order, and batch capacity. Signed-off-by: JmPotato <github@ipotato.me>

Addressed in 83b2325. The G602 in checkStoreRegions is now addressed by asserting Count == 1 and len(Regions) == 1 before comparing the sole ID with 4. This intentionally strengthens the test: the previous code accepted Count == 1 with an empty array, and panicked for extra matching entries. No server behavior is changed.
The other key-range G602 is addressed in a shared keyutil.BuildKeyRangeMaps helper. It converts each pair to [2]string before accessing its elements. The two private test helpers are removed, and the labeler and keyspace builders reuse the same implementation. labeler.MakeKeyRanges remains as a compatibility entry point. Empty input still returns nil, pair order and values are unchanged, and odd input still panics (the runtime panic text changes).
I also reviewed the remaining suppressions. Removing all of them would require changes beyond behavior-preserving Go/tooling adaptation:
checkRules/ G602: the existingrequire.Lenalready guarantees matching lengths before comparison. Keeping the per-element assertions preserves the useful expected/actual diagnostics; replacing them with a boolean slice comparison offers little benefit here.- TLS / G123:
VerifyConnectionalso runs on resumed connections, unlike the existing callback. Migrating would change which connections are accepted; explicitly skipping resumptions would merely preserve the issue behind a different callback. - Dashboard
Director/ SA1019:Rewritechanges forwarding-header handling, hop-by-hop processing order and query normalization. A direct substitution is not equivalent. - Contexts / G118:
OrderedSingleFlightalready stores and invokes cancel on cancellation/completion. The router and benchmark findings concern existing lifecycle handling; adding a constructor-leveldefer cancel()or deleting the child contexts changes that lifecycle. - Dynamic URLs / G704 and G710: proxying to discovered/configured endpoints, dashboard redirects and the test harness URL are existing functionality. Adding target/scheme restrictions or changing URL normalization would change the supported behavior.
- Pyroscope / SA1019: the pinned v1.2.0 client requires the
AuthTokenfield during initialization for its legacy cloud endpoint. Replacing it with an Authorization header would fail that check and can change authentication precedence. - pd-ut / G702 and G706: executing the selected test binary and passing Go arguments are intentional runner functionality; escaping compiler diagnostics changes log output. Merely switching to calls the analyzer does not recognize would not fix the underlying concerns.
recvcheck: the mixed serialization receivers preserve method sets and mutation semantics. Unifying their receivers would change interface satisfaction or deserialization behavior.
These local exceptions preserve the current scope; they are not a claim that all pre-existing findings are harmless. Behavioral/security hardening should be reviewed separately rather than hidden inside the toolchain upgrade.
Validation: make check passed with Go 1.26.8 and golangci-lint v2.13.2 (reusing the generated dashboard assets). The keyutil/labeler suites and relevant keyspace, merge/split checker, region API and pd-ctl tests passed with race/deadlock enabled in both normal and nextgen configurations.

What problem does this PR solve?
PD uses the Go 1.25 release line and golangci-lint v2.6.0, so it cannot validate builds and static analysis against Go 1.26 and the current lint rules.
