BREAKING CHANGE: the Go module path is now github.com/tiennm99/tiennm99bot,
the default sticker pack is stickers_by_<bot username>, and the health body,
deploy DM, User-Agents and image names say tiennm99bot.
Correct comments that described the retired webhook transport, a removed
/cron route, the old KV store and wrapper types, and behaviour that has since
changed; drop plan and review labels; reword two startup log lines that
overstated or misnamed what they report.
Telegram expires an inline query and then rejects the answer with "query
is too old and response timeout expired or query ID is invalid". The
picker invited that: it listed the names and then read the store once per
name — up to 50 round trips per keystroke — and it was the only handler
in the module with no deadline of its own. Updates are dispatched one at
a time, so a single slow answer also held up the queries queued behind
it, each ageing while it waited, and one slow read expired a whole burst
of typing.
Add DocStore.Scan, which reads a key prefix with its values in one round
trip, ordered by key. The picker and /aliases both use it, so neither
grows a round trip per saved alias. Bound the inline handler at 3s: an
answer later than that is rejected anyway, and giving up frees the worker
for the fresher query behind it. When Telegram does reject an answer, the
error now carries how long it took, which separates a slow handler from a
query that was already stale on arrival.
The 50-result cap now counts results the picker can show, so a video-note
alias — which has no cached inline type — no longer consumes a slot.
Delete the byte-oriented KVStore/VersionedStore abstraction and the
DynamoDB/memory KV backends. Add a generic typed store (DocStore[T] with
Provider/Collection/Typed) persisting each value as a flattened native
Mongo document (storedDoc[T] via bson inline) — no value envelope.
- MongoDB is the only runtime backend; memory kept for tests/local.
- All modules + deploynotify use typed stores; persisted structs carry
bson tags == json names (incl. nested lolschedule/wordle types).
- lolschedule wraps its array/scalar values in named structs.
- migrate-dynamo-to-mongo writes the flattened shape via Typed[bson.M]
with wrap rules; Scan/--dry-run/--verify retained.
Verified: go vet/build clean; full go test green hermetically and
in-container vs real Mongo 7 + DynamoDB Local (storage integration +
migrator e2e).
Delete Firestore provider implementation and tests (5 files). Extract shared
key helpers to new internal/storage/keys.go module. Remove Firestore case
from server bootstrap and storage factory. Drop cloud.google.com/go/firestore
and related dependencies from go.mod. Remove firestore-emulator test targets
from Makefile. Update README storage section to reflect MongoDB-only backend.
Replace content-addressed storage versioning (CAS) with explicit version fields
on documents. Versions are managed via optimistic locking pattern: Get returns
version, Put increments atomically and fails if version mismatch detected.
Callers (portfolio, lolschedule) updated to use GetVersioned/PutVersioned,
simplifying concurrency handling and eliminating CAS overhead.
Persist the KV value field as a BSON string so it is directly readable in
the Atlas/Compass UI, matching DynamoDB's String storage. Reads still accept
BSON binary as a backward-compat fallback. Non-UTF-8 callers must encode
upstream, same constraint as DynamoDB; all current callers write JSON.
- prefix.go: return errors.ErrUnsupported when inner store lacks CompareAndSwap, enabling fail-fast instead of infinite retries
- Adds comprehensive CAS semantics test coverage for all KV backends:
* memory_kv_test.go: new tests for basic operations and CAS failures
* prefix_test.go: tests for wrapped CAS errors and unsupported operations
* dynamodb_kv_test.go, firestore_kv_test.go: CAS failure scenarios
- portfolio_test.go: test retry exhaustion, business-error short-circuit, concurrent updates, and fail-fast on unsupported CAS
Operator-run tooling that moves durable Cloudflare KV data into the live
AWS DynamoDB table, plus a runtime swap of the `value` attribute from
Binary to String so payloads are human-readable in the AWS console.
- cmd/migrate_cf_data: subcommands inventory, kv-import (idempotent via
attribute_not_exists), trading-audit-dump, convert-value-to-string
- internal/migration: policy allowlist, CF KV+D1 REST clients, DynamoDB
writer, report formatter with per-prefix counts + tests
- internal/storage/dynamodb_kv.go: Put writes MemberS, Get reads MemberS;
dropped empty-bytes sentinel (DynamoDB allows empty strings)
Rename:
- Go module github.com/tiennm99/miti99bot-go → github.com/tiennm99/miti99bot
- CloudFormation stack miti99bot-aws-port → miti99bot
- Drop "port", "Cloud Run", "GCP", "cutover", "Phase NN" framing from
active code and docs — project reads as canonical AWS-Lambda from now on.
AWS deploy guide + flow fix:
- New docs/deploy-aws-free-tier-guide.md — Ubuntu 24.04 ARM64 onboarding
with project-local venv (pip awscli + sam-cli), SSM secrets via read -s,
idempotent OIDC provider + role creation, $1 budget alarm.
- Drop sam build from the pipeline — provided.al2023 + makefile builder
expects a Makefile in CodeUri (build/lambda/, the output dir), so the
step always fails. sam deploy --template-file template.yaml now reads
the raw template and zips build/lambda/ directly.
- Rollback section rewritten — use continue-update-rollback /
cancel-update-stack / git-SHA redeploy. Drop the broken
--use-previous-template recipe.
- DynamoDB free-tier row corrected (on-demand is 2.5M read / 1M write
request units, not 25 RCU/WCU).
Updated:
- README.md fully rewritten (drops port/legacy framing, lists modules,
points new users at the free-tier guide).
- aws/README.md retitled "AWS account setup", phase numbers stripped.
- Makefile / .github/workflows/deploy.yml — sam deploy flow.
- samconfig.toml — stack_name = "miti99bot".
- Go comments — Cloud Run → Lambda, Cloud Scheduler → EventBridge
Scheduler, Cloud Logging → CloudWatch Logs.
- Struct field GCPProject → FirestoreProject (env GOOGLE_CLOUD_PROJECT
unchanged).
Plus advisory reports under plans/reports/ from the code-reviewer +
researcher passes that informed the fixes.
Verified: go vet ./..., go build ./..., go test ./... all green.
Removes six modules (loldle-ability/emoji/quote/splash, semantle, doantu)
and prunes the framework deps that were only there to serve them:
- ai.Embedder + Client.Embed + embeddingModel const (semantle only)
- Deps.Embedder + BuildOptions.Embedder
- Deps.Env + Build(env) param + ModuleEnv config field + PHOW2SIM allowlist (doantu only)
- internal/champname package (loldle now owns its lookup helpers directly)
- template.yaml: Phow2simAPIURL parameter + PHOW2SIM_API_URL Lambda env
Active catalog: util, misc, wordle, loldle, lolschedule, twentyq, trading.
go build / vet / test all pass.
- Implement DynamoDB client wrapper and KV provider
- Full CRUD test coverage for both local and AWS modes
- AWS SDK v2 dependency added to go.mod/go.sum
Phase 6 of the 2026-05-09 review remediation plan. Bundle of small
hygiene fixes — none individually urgent but better folded together
than scattered across follow-ups.
- .golangci.yml: enable errcheck/govet/gosec/staticcheck/unused/
ineffassign/gocyclo/misspell/revive. Tuned to the codebase style
(no universal exported-doc requirement, gocyclo cap at 20 to
accommodate handler dispatch). 0 issues across the tree.
- ci.yml: add golangci-lint job + govulncheck (informational).
- Defensive guards:
- registry.go: Module.Name mismatch now errors at Build instead of
silently overwriting (TestBuild_RejectsFactoryNameMismatch).
- cmd/server/main.go: PORT env validated numerically + 0..65535.
- firestore_provider.go: For() re-validates module name; invalid
names return an invalidStore whose every op errors with
ErrInvalidModuleName.
- Dead code removal:
- wordle: gameTTLSeconds const + pickDaily/hashDJB2/todayUTC
helpers + their tests deleted (pickDaily was unused;
daily.go renamed pick_random.go).
- Dependency: golang.org/x/net v0.52.0 -> v0.54.0 (resolves
GO-2026-4918 HTTP/2 infinite-loop CVE).
- Deferred from the original phase plan: Docker digest pinning
(Dependabot handles), per-handler file splits (largest file 279 LOC;
splits would churn for marginal gain).
go test -race -count=1 ./... clean (15 packages); golangci-lint run
clean (0 issues).
Implements Phases 02 (partial) and 03 of the go-port-cloud-run plan.
Introduces module framework with per-module KV prefix isolation,
health check endpoint, request timeout protection, and comprehensive
test coverage. Cloud Run deployment deferred to Phase 01.
Security hardening: constant-time secret comparison, cron auth bridge,
and secrets stripped from dependency environment exports. Includes
Dockerfile, GitHub CI workflow (vet + race + build), and integration
tests for module lifecycle.
