Scanned commit 99c395d846e079d4cffd29de9298d1dd829e8b04 (2026-10-01). Generated by codevetter codevetter 1.15.0 on 2026-10-02.

Source inspection; upstream code and tests were not executed.

Tests and CI were inspected, not executed; their existence establishes intended checks, not passing results. The examined tests use Go testing, httptest, testify assertions, and filesystem fixtures. They target dispatch/pool invariants, JSON parsing, static security regressions, concurrency, lifecycle behavior, proxying, and rate-limit headers. Inspection is bounded and does not establish exhaustive coverage, deployment correctness, or measured performance.
- Tests use testing, httptest, and testify/assert; echotest.ContextConfig constructs request bodies, headers, route metadata, and recorders. ServeWithHandler invokes a handler directly and applies an error handler, so that helper alone does not exercise router/global middleware dispatch. — [dispatch_pool_test.go#L6-L12](https://github.com/labstack/echo/blob/99c395d846e079d4cffd29de9298d1dd829e8b04/dispatch_pool_test.go#L6-L12) [echotest/context.go#L80-L106](https://github.com/labstack/echo/blob/99c395d846e079d4cffd29de9298d1dd829e8b04/echotest/context.go#L80-L106) [echotest/context.go#L137-L183](https://github.com/labstack/echo/blob/99c395d846e079d4cffd29de9298d1dd829e8b04/echotest/context.go#L137-L183)
- CI specifies Go 1.25, 1.26, and 1.27 on Ubuntu, macOS, and Windows, running go test -race with atomic coverage. Coverage uploads are limited to the latest configured Go on Ubuntu and do not fail CI on upload errors; Codecov config permits a one-percent status threshold. — [.github/workflows/ci.yml#L38-L45](https://github.com/labstack/echo/blob/99c395d846e079d4cffd29de9298d1dd829e8b04/.github/workflows/ci.yml#L38-L45) [.github/workflows/ci.yml#L81-L98](https://github.com/labstack/echo/blob/99c395d846e079d4cffd29de9298d1dd829e8b04/.github/workflows/ci.yml#L81-L98) [codecov.yml#L1-L11](https://github.com/labstack/echo/blob/99c395d846e079d4cffd29de9298d1dd829e8b04/codecov.yml#L1-L11)
- The checks workflow installs and runs golint, staticcheck, and govulncheck using @latest. Separately, .golangci.yaml enables revive, disables errcheck, and excludes test files; these workflow steps do not invoke golangci-lint. — [.github/workflows/checks.yml#L70-L84](https://github.com/labstack/echo/blob/99c395d846e079d4cffd29de9298d1dd829e8b04/.github/workflows/checks.yml#L70-L84) [.golangci.yaml#L1-L24](https://github.com/labstack/echo/blob/99c395d846e079d4cffd29de9298d1dd829e8b04/.golangci.yaml#L1-L24)
- dispatch_pool_test.go guards store clearing, JSON status across Reset, nested JSON writer behavior, and Pre/Use execution for 404, 405, and OPTIONS. Query fast-path tests compare malformed escapes, repeated keys, empty values, Unicode, and semicolon segments against url.ParseQuery. — [dispatch_pool_test.go#L14-L51](https://github.com/labstack/echo/blob/99c395d846e079d4cffd29de9298d1dd829e8b04/dispatch_pool_test.go#L14-L51) [dispatch_pool_test.go#L70-L100](https://github.com/labstack/echo/blob/99c395d846e079d4cffd29de9298d1dd829e8b04/dispatch_pool_test.go#L70-L100) [query_fastpath_test.go#L32-L66](https://github.com/labstack/echo/blob/99c395d846e079d4cffd29de9298d1dd829e8b04/query_fastpath_test.go#L32-L66)
- JSON tests reject trailing objects/garbage, alternate large and small payloads, exercise pooled decoding in 64 goroutines, decode a body above the pool-retention cap, and check read failures. These inspect parser/pool behavior rather than proving endpoint request-size limits. — [json_test.go#L118-L174](https://github.com/labstack/echo/blob/99c395d846e079d4cffd29de9298d1dd829e8b04/json_test.go#L118-L174) [json_test.go#L177-L215](https://github.com/labstack/echo/blob/99c395d846e079d4cffd29de9298d1dd829e8b04/json_test.go#L177-L215) [json.go#L43-L46](https://github.com/labstack/echo/blob/99c395d846e079d4cffd29de9298d1dd829e8b04/json.go#L43-L46)
- Static regression tests combine guarded routes with fstest.MapFS and assert no protected content appears for encoded slash, backslash, or double-encoding variants. Group-mounted StaticFS receives separate encoded-separator cases; these fixtures do not establish behavior for every custom filesystem. — [static_encoded_separator_test.go#L12-L79](https://github.com/labstack/echo/blob/99c395d846e079d4cffd29de9298d1dd829e8b04/static_encoded_separator_test.go#L12-L79) [static_encoded_separator_test.go#L83-L122](https://github.com/labstack/echo/blob/99c395d846e079d4cffd29de9298d1dd829e8b04/static_encoded_separator_test.go#L83-L122)
- Inspected tests include concurrent route metadata reads during additions, graceful-shutdown completion/deadline branches, and preference for AllowContext plus 429/rate-limit headers. These are concrete concurrency/lifecycle contracts, with no execution result supplied by this investigation. — [router_concurrent_test.go#L295-L355](https://github.com/labstack/echo/blob/99c395d846e079d4cffd29de9298d1dd829e8b04/router_concurrent_test.go#L295-L355) [server_test.go#L132-L225](https://github.com/labstack/echo/blob/99c395d846e079d4cffd29de9298d1dd829e8b04/server_test.go#L132-L225) [middleware/rate_limiter_context_test.go#L38-L88](https://github.com/labstack/echo/blob/99c395d846e079d4cffd29de9298d1dd829e8b04/middleware/rate_limiter_context_test.go#L38-L88)
- Proxy tests arrange reachable and unreachable targets plus retry filters and a WebSocket echo exchange; CSRF tests cover fetch-metadata allow/block branches. PR benchmark CI compares base/current checkouts with eight 100 ms samples and advisory benchstat output, which provides no measured speedup in this report. — [middleware/proxy_test.go#L637-L677](https://github.com/labstack/echo/blob/99c395d846e079d4cffd29de9298d1dd829e8b04/middleware/proxy_test.go#L637-L677) [middleware/proxy_test.go#L1081-L1118](https://github.com/labstack/echo/blob/99c395d846e079d4cffd29de9298d1dd829e8b04/middleware/proxy_test.go#L1081-L1118) [middleware/csrf_test.go#L535-L608](https://github.com/labstack/echo/blob/99c395d846e079d4cffd29de9298d1dd829e8b04/middleware/csrf_test.go#L535-L608) [.github/workflows/ci.yml#L100-L142](https://github.com/labstack/echo/blob/99c395d846e079d4cffd29de9298d1dd829e8b04/.github/workflows/ci.yml#L100-L142)
