Summary

Implements mid-game match progress telemetry and resolved side persistence for GeneralsOnline (NGMP) multiplayer matches in GameClient.

Problem Solved

  1. Random faction recorded as -1: In pre-game staging lobbies, selecting "Random" stores template index -1. Previously, CommitMyOutcome read this directly from pLocalSlot->getPlayerTemplate(), recording side: -1 in the database.
  2. Incomplete stats / -1 side on player disconnection: Outcome reporting was only dispatched at match conclusion from ScoreScreen. When a player dropped or disconnected mid-game, their side remained -1 and their combat statistics (kills, losses, cash) were lost.

Changes

  • Faction Resolution (ResolveLocalPlayerSide): Added helper that inspects ThePlayerList->getLocalPlayer()->getPlayerTemplate() against ThePlayerTemplateStore when the lobby template is -1, accurately resolving the rolled faction.
  • Initial Frame 0 Match Progress: In GameLogic.cpp, immediately after loading screen cleanup (deleteLoadScreen()), dispatches SendMatchProgress(true) (POST /Lobby/MatchProgress) to sync the rolled side and initialize slot stats.
  • Periodic Telemetry (every 120s): In OnlineServices_Manager.cpp::update(), tracks active match duration and periodically calls SendMatchProgress(false) to sync buildings/units/money.
  • CommitMyOutcome Fallback: Updated final match outcome reporting to use ResolveLocalPlayerSide.
  • Worklog: Documented changes in docs/WORKLOG/2026-10-DIARY.md.

Summary by CodeRabbit

  • New Features
    • Match progress is reported after loading completes and every two minutes during an active multiplayer match.
    • Reports include the local player’s score and faction when available, including when the player selected Random.
    • Initial reports are retried when sending fails, and expired authentication is refreshed so reporting can continue.
    • Reports apply only to the current match and stop when there is no active match or local player. Reports from an earlier login session are not sent after the session changes.

Send initial match progress upon loading screen completion to persist rolled Random faction immediately, preventing early drops from recording as Side #-1. Add periodic 120s combat progress updates during active multiplayer matches and fix Random side resolution fallback in CommitMyOutcome.

📝 Walkthrough

Walkthrough

The change adds initial and periodic match-progress reporting. Reports include match and score data, plus the player side when it resolves to a nonnegative value. The stats interface submits reports and handles retries and token refresh.

Changes

Match Progress Telemetry

Layer / File(s) Summary
Track session and match state
GeneralsMD/Code/GameEngine/Include/GameNetwork/GeneralsOnline/OnlineServices_Manager.h, GeneralsMD/Code/GameEngine/Source/GameNetwork/GeneralsOnline/OnlineServices_Auth.cpp
The manager tracks session generation and periodic-report state. Successful logins and logout increment the session generation. Logout clears the user ID and resets match tracking.
Build and submit progress reports
GeneralsMD/Code/GameEngine/Include/GameNetwork/GeneralsOnline/OnlineServices_StatsInterface.h, GeneralsMD/Code/GameEngine/Source/GameNetwork/GeneralsOnline/OnlineServices_StatsInterface.cpp
The stats interface adds SendMatchProgress. Side resolution uses the lobby slot’s template index, then checks the active local player’s template store if that index is negative. CommitMyOutcome uses the same resolution. Reports include available score totals and omit an unresolved side. Requests do not overlap. Initial reports allow up to three attempts; periodic reports allow one. The worker validates the originating user and session, and can refresh a token after an eligible 401.
Trigger initial and periodic reports
GeneralsMD/Code/GameEngine/Source/GameLogic/System/GameLogic.cpp, GeneralsMD/Code/GameEngine/Source/GameNetwork/GeneralsOnline/OnlineServices_Manager.cpp, docs/WORKLOG/2026-10-DIARY.md
Game loading triggers an initial report after the loading keepalive stops. The update loop triggers reports every 120 seconds when match and local-player conditions are met. The worklog records the telemetry behavior.

Merge Risk: ⚪ Minimal · up to e593e

Progress reports from an earlier login cannot be retried with a later login’s token. No actionable merge-blocking issue remains after normal checks.

Security Architecture Review

Security architecture risk: 🟡 Moderate · up to e593e

The new background reporting adds useful stale-session checks, but it also creates additional opportunities for an existing refresh race to restore credentials after sign-out. Server-side ownership and update-ordering guarantees remain unverified.

Retained concerns

  • Medium · security · inferred: Initial and recurring progress reports add refresh callers to a pre-existing refresh/logout race. A refresh started for one session can complete after logout or account replacement and overwrite the shared token and credential files without validating session ownership. Post-refresh worker checks abort the stale report but cannot undo those writes, so request isolation does not fully preserve credential cleanup or account-state ownership.
Security review details

Security Blast Radius

  • inferred — The credential race affects the client's shared authentication state and credential files. During account replacement it can combine a later user identity with an earlier account's refreshed token. It requires an existing credential, a successful refresh response, and concurrent logout or login; an unauthenticated remote trigger or broader tenant and infrastructure exposure is not established.

Security Findings and Attack Paths

  • inferred — A progress worker can begin refreshing with account A's saved credential, then logout can clear shared and stored credentials while the request is in flight. A successful late response subsequently writes the session token and, when returned, a rotated refresh token. The worker detects its stale generation only afterward. A later beginLogin can select the restored refresh credential for silent login, weakening sign-out guarantees on that client.

Trust Boundaries and Controls

  • observed — Reports crossing the API boundary contain client-selected match IDs and statistics authenticated with bearer credentials. Generation checks block workers when a session transition has already completed. A transition after the attempt check can still leave an in-flight POST using its captured old token; this is not evidence that the worker adopts a later account's token or that the server accepts unauthorized writes.

Resilience and Maintainability Implications

  • observed — The refresh mutex serializes refreshes, and the authentication mutex protects individual state updates. Logout does not acquire the refresh mutex, and refresh completion does not validate session generation before updating memory and disk. Existing outcome and global-statistics requests already use this helper; the PR's additional progress callers expose the same ownership weakness at new lifecycle points.

Hardening Proposals

  • proposed — Make refresh completion a session-owned commit: capture identity and generation with the credential, then reject stale responses before updating either shared state or credential files. Coordinate that commit with logout and login so persistence cannot restore invalidated credentials.
  • proposed — Establish the server contract for authenticated match membership, idempotent progress delivery, and rejection of stale updates after final outcomes. These are validation targets, not observed server vulnerabilities.

- Line 300: Update the request worker launched by the `std::thread` in the stats
reporting flow to retain whether the POST is an initial report. If an initial
report fails with a timeout or a non-401 error, keep it pending for that match
and retry with bounded backoff until the server accepts it; preserve the
existing handling for 401 responses.
- Line 312: Update the progress-report flow around the authToken check so
neither the initial POST nor its retry is sent unless a non-empty bearer token
is available; defer the report until a token can be obtained, and retain
Authorization: Bearer authentication on both requests.
- Line 317: Update SendMatchProgress before configuring or performing the
libcurl request to reject URLs that are not HTTPS; if development requires HTTP,
allow it only for an exact loopback authority. Ensure the bearer token is never
sent to a non-loopback HTTP endpoint.

GeneralsMD/Code/GameEngine/Source/GameNetwork/GeneralsOnline/OnlineServices_StatsInterface.cpp:353-369
🗄️ Data Integrity & Integration | 🟡 Minor | ⚡ Quick win

Keep match-progress retries bound to the originating account.

If another account logs in before the 401 retry, logout and login advance m_authTokenVersion. refreshSessionTokenSync(tokenVersion) then returns success because the version is newer, and the worker retries its captured match payload with the new account’s bearer token. The in-flight gate does not cancel or rebind that worker. Bind both refresh paths—the empty-token path and the 401 path—to the account/session captured with the payload, and abort if it changes. This establishes a cross-session client request; it does not establish server acceptance or persistence.

@coderabbitai Addressed in 757dde2. Bound SendMatchProgress worker and all token refresh / retry paths to the originating account session (originatingUserId), aborting the worker if the user logs out or switches accounts before sending.
