Adds a `request_replay_review` lobby command. It validates the content fields of a review request, stamps the requesting player from the authenticated connection, and publishes the result to the topic exchange with routing key `request.replay_review.create`. The lobby neither answers the request nor knows who will. A consumer bound to that key renders it into a post wherever reviews are actually answered. The reason the request takes this detour at all is identity: a client posting straight to a chat service can claim to be anyone, while a client on this socket has already authenticated, so `player_id` and `login` are the server's word rather than the client's. Requests are rate limited per player before publishing, so a rejected request never reaches the bus.

- Around line 198-202: Update ReplayReviewService.submit to reserve the player’s
cooldown timestamp before awaiting MessageQueueService.publish, preventing
concurrent submissions for the same player from passing the check. If
publication fails or is cancelled, remove the reservation so a later submission
can proceed; preserve the existing cooldown behavior on success. Add a
regression test that blocks the first publish and starts a second submission for
the same player, verifying the second is rejected.

Preserve the numeric type for environment overrides.
When REPLAY_REVIEW_COOLDOWN_SECONDS=3600 is set, ConfigurationStore.refresh stores "3600" as a string. On a second submission, ReplayReviewService._prune evaluates now - at < cooldown and raises TypeError instead of returning the rate-limit notice. Coerce this environment value to an integer before storing it.

On the red Codacy check, in case it looks like something to fix: it has both The one escape is a single-line docstring, which triggers neither. I have used that where it costs nothing — the constructor and the one test that was flagged. That leaves a single annotation, on the module docstring of Every other check passes, including unit tests, mypy, flake8, isort and codecov. |
A connection's messages are dispatched one at a time, so two requests from one player could only overlap while they have two connections open. The ordering costs nothing either way, and rolling the claim back when the publish raises is worth having on its own: a request that never reached the broker should not cost the player their turn.

Thanks — took one of the two. Cooldown claimed before the publish: done in 29f3a00, with a rollback when the publish raises and two regression tests. The race itself is narrow, since Coercing the config value to |

Adds a
request_replay_reviewlobby command. It validates the content fields of a replay review request, stamps the requesting player from the authenticated connection, and publishes the result to the topic exchange with routing keyrequest.replay_review.create.The lobby neither answers the request nor knows who will. A consumer bound to that key turns it into a post wherever reviews are actually answered — the intended first one is a forum post by faf-qai, which is a separate PR and not required for this one to be safe to merge.
Why this goes through the lobby at all
Identity. A client posting straight to a chat service can claim to be anyone, which is what sank the earlier proposals. A client on this socket has already authenticated, so
player_idandloginare the server's word rather than the client's. Nothing else in the feature needs the lobby.What is in here
server/replay_review_service.py— validation, the rate limit, and the publish. The wire contract is documented in the module docstring.command_request_replay_reviewonLobbyConnection, next to the other party/veto commands.REPLAY_REVIEW_COOLDOWN_SECONDSinconfig.py.Three decisions worth looking at
The client cannot name a replay by url. The payload takes
replay_idonly. The client also knows how to name a replay by link or by a local file, but a link would let the client decide what a review post points at, and a file nobody else can fetch is not a review request. Those keep using the client's existing copy-and-paste path.Identity is dropped at the parser, not overwritten later.
parse_review_requestreturns content fields only, and the caller addsplayer_id/login. There is deliberately no ordering of operations in which a client-supplied value survives —test_submit_ignores_identity_the_client_tried_to_setpins that end to end.The rate limit is in memory. One request per player per 24h, per lobby instance, lost on restart. That makes it a spam guard rather than a quota. The cost of a duplicate is a duplicate post, and the alternative is a schema migration plus a database write on a path that has no other reason to touch the database. Rejections happen before publishing, so an over-limit request never reaches the bus. Happy to change this if you would rather have it durable — it is contained in one service.
Deploying this alone is a no-op
With no queue bound to the routing key, published messages go nowhere and cost nothing. That makes the rollout order lobby-first, and unbinding the queue later is the off switch — no client release, no code change.
Not covered
The lobby sends nothing back on success and answers a rejection through the existing
noticepath, the same ascommand_invite_to_party, so a client shows success optimistically. If an explicit acknowledgement is wanted that is a new server→client command, and better decided before clients are written against it. Noted as the fifth question in FAForever/faf-java-api#1181.Tests
tests/unit_tests/test_replay_review_service.py— parsing, the identity stamp, the rate limit, and that a rejected request never reaches the broker.tests/unit_tests/test_lobbyconnection.py— the command wiring, including that an unauthenticated connection never reaches the handler.flake8andisortare clean on the changed files. The suite itself I could not run locally — it wants Python 3.13 plus MySQL and RabbitMQ — so CI here is the first full run.Summary by CodeRabbit
