Addresses coordinator review of the Task 15 integration suite: 1 critical
ruling, 5 important, 3 folded. make integration now exits 0.
- integration_test.go: TestStreamingIncrementalityProbe restructured —
content assertion (5 deltas + [DONE], in order) always runs; the raw-TCP
timing assertion (unchanged, >=3 gaps >=100ms) is gated behind
INTEGRATION_STREAMING=1 with t.Skipf naming traefik/traefik#10269,
verified to still genuinely fail when re-armed (not silently disabled).
- Makefile: integration-up/integration-wait moved from prerequisites into
the integration recipe body as go test ./... -count=1
ok github.com/lukaszraczylo/traefik-llmgateway 6.065s sub-invocations with per-stage
status capture, so integration-down always runs even when bring-up or
the health wait fails; verified with a synthetic failure. Added
.NOTPARALLEL (the integration targets are stateful).
- translate_gemini.go: fixed the same yaegi multi-value-assignment panic
shape as the prior sse.go fix, on the live max_tokens path. Added a
gemini chat completion assertion to integration_test.go (renamed
TestUnifiedChatAllProviders) so this path now runs under real Yaegi.
- providers.go, translate_anthropic.go: documented the never-wrap
contract on providerHTTPError/translateError (routes_unified.go asserts
their concrete type directly; errors.As panics under yaegi on these).
- integration_test.go: TestCrossReplicaLimits now FLUSHALLs Redis first,
for idempotence under integration-keep.
- mock/main.go: probe's header-terminator search now accumulates a
rolling buffer across reads instead of only checking the latest one.
- Folded: hot-reload deadline 10s -> 20s; dynamic.yml's real-upstream
baseUrl is now a template (dynamic.yml.tmpl) rendered via
INTEGRATION_REAL_BASEURL (default https://llmgw.example.com), not a
hardcoded-only hostname.
See task-15-report.md's addendum for full verification detail.
Add tools/yaegi-check, a separate Go module (llmgw-yaegi-check,
never a dependency of the plugin module) that replicates the
Traefik Plugin Catalog analyzer (piceus)'s yaegiMiddlewareCheck:
copy the repo into a temp GOPATH, interp.New + i.Use(stdlib.Symbols),
import the plugin package, eval CreateConfig(), decode the plugin's
real .traefik.yml testData into it via a hand-rolled YAML-subset
parser plus a JSON round-trip, reflect-Call New from outside the
interpreter, then exercise the returned handler with two real HTTP
requests (authenticated GET /v1/models against the testData key, and
the same route unauthenticated). Pins github.com/traefik/yaegi to
v0.16.1, confirmed as Traefik v3.5.0's own vendored version by
downloading its go.mod.
Wire cd tools/yaegi-check && GOWORK=off go run . /Users/nvm/Documents/projects/private/traefik-llmgateway
yaegi-check: OK to run the harness from repo root.
The harness caught a real Yaegi v0.16.1 limitation: calling a struct
FIELD of variadic func type (e.g. modelRegistry.log
func(string, ...any)) with two or more variadic arguments crashes
Yaegi's CFG builder ('index out of range'). The identical call shape
through a method or interface method is unaffected — bisected with a
standalone yaegi repro to confirm the exact trigger before touching
plugin code. Fixed by pre-formatting with fmt.Sprintf at
modelRegistry's three affected call sites (registry.go) so the field
is always called with exactly one variadic argument; documented the
constraint on both modelRegistry.log and limiter.logf so it is not
reintroduced. Verified the gate itself is load-bearing by temporarily
renaming CreateConfig (harness failed non-zero) and restoring it
(harness passed again).
Also fixes two golangci-lint findings in the new harness module
(govet shadow, gosec G301 directory permissions).
