 # AGENTS.md — vnctalk-prosody
 ## What this repo is
 Dockerized Prosody 0.11.6 XMPP server for VNCtalk. It builds Prosody from source, applies patches to core upstream files, and bundles custom Lua modules. There is no language package manager or test framework.
 ## Build & verification
 - **Only build command:** `docker build -t <tag> .`
 - No `make`, `npm`, rockspec tests, or linting exists.
 - `test.sh` is a **manual integration helper** that runs the container with a long list of required env vars. It is not an automated test suite.
 - **Python test suite** lives in `tests/`. It is an optional pytest/slixmpp integration suite used to verify a running XMPP server against VNCtalk requirements.
  - Set up: `python3 -m venv tests/venv && source tests/venv/bin/activate && pip install slixmpp pytest pytest-asyncio aiohttp`
  - Run dry (no server): `pytest tests/ -v --skip-live -c tests/pytest.ini`
  - Run against a server: set `XMPP_JID`, `XMPP_PASSWORD`, `XMPP_DOMAIN`, `MUC_DOMAIN`, etc., then `pytest tests/ -v -c tests/pytest.ini`
 ## Code layout
 | Path | Purpose |
 |------|---------|
 | `patches/` | Overrides for upstream Prosody core files (e.g., `mod_mam.lua`, `mod_muc.lua`, `moduleapi.lua`). Copied over the upstream source during the Docker build. |
 | `vnctalk/` | Custom Prosody Lua modules. Copied wholesale to `/usr/local/lib/prosody/modules/` in the image. |
 | `config/` | Runtime templates and shell scripts. |
 - `patches.list` is **stale and unused** by the build; the Dockerfile hardcodes each `cp` command. If you add a patch, update the Dockerfile `RUN cp …` block.
 ## Configuration
 - The real config source is `config/prosody.cfg.lua.template`. At container startup, `startup.sh` renders it with `envsubst` to `/etc/prosody/prosody.cfg.lua`.
 - **Edit the template**, not a generated `.cfg.lua` file.
 - Template variables use `${VAR}` syntax. Required runtime env vars include: `prosodyDomain`, `prosodyDBhost`, `prosodyDBname`, `prosodyDBuser`, `prosodyDBpass`, `hybridaAuthUrl`, `fcmApiKey`, `fcmApiUrl`, `fileShareBaseUrl`, `fileShareSecret`, `avatarUploadUrl`, `avatarUploadUser`, `avatarUploadPass`.
 ## Runtime quirks
 - `startup.sh` (main container) generates certs, renders config, and runs `/usr/local/bin/prosody -F`.
 - `startup-sidecar.sh` runs a separate Node `http-server` on port 8080 for static files (redirect page, status page). This is **not** the XMPP server.
 - `healthcheck.sh` compares `/etc/tls-update/tls.crt` with the currently loaded cert. If they differ, it exits **2** (not 1) to force a container restart so the new cert is picked up. It then checks TCP port 5582 (admin telnet).
 ## CI / deploy
 - GitLab CI (`.gitlab-ci.yml`). Builds push to Google Container Registry (`eu.gcr.io`).
 - `main` branch builds a `development` image.
 - Git tags matching `prod-*` or `stable-*` trigger promotion jobs that **retag** the existing dev image rather than rebuilding.
 ## Module conventions
 - Lua 5.2. Modules follow Prosody conventions (`module:hook`, `module:open_store`, `module:get_option_string`, `module:provides`).
 - Authentication is delegated to an external HTTP endpoint via `mod_auth_http_async`.
 - Push notifications are handled by `mod_vnc_fcm` (and `mod_vnc_fcm_hin`) using a configurable FCM proxy URL.
 - `mod_http_rest` exposes an HTTP endpoint at `/rest` that accepts `text/xml` bodies and injects them as XMPP stanzas into the server.

 # VNCtalk Prosody Patches & Custom Modules Analysis
 This document describes how the VNCtalk Prosody distribution deviates from upstream Prosody 0.11.6. The deviations are delivered as:
 - **`patches/`** — direct replacements for upstream core files
 - **`vnctalk/`** — additional custom modules
 > **Note:** `patches.list` is stale and unused. The Dockerfile hard-copies each patch in a `RUN cp …` block.
 ---
 ## 1. Core Patches (`patches/`)
 ### 1.1 `mod_mam.lua` → `modules/mod_mam/mod_mam.lua`
 **Purpose:** Message Archive Management (XEP-0313) for 1:1 chats.
 **Key deviations from upstream:**
 - **`vnc-rest-message` hook support:** Added `vnc_message_handler(event)` hooked on `vnc-rest-message` (priority 0). This allows the REST injection module (`mod_http_rest`) to archive messages that are injected via HTTP.
 - **Store-user logic for REST:** When `vnc_rest` is true, `store_user` is derived from `orig_from` instead of `orig_to`, so injected stanzas are archived under the sender's archive.
 - **`shall_store` always returns true:** The function `shall_store(user, who)` unconditionally returns `true`, bypassing any roster-based archive filtering.
 - **Archives normal messages with body:** The condition `orig_type == "chat" or (orig_type == "normal" and stanza:get_child("body"))` is kept but the implementation now also processes `vnc-rest-message` events.
 **Behavioural contract:**
 - Any message injected via `/rest` (see `mod_http_rest`) must be archived under the sender's MAM archive.
 - MAM queries must return `stanza-id` elements and support RSM pagination.
 ---
 ### 1.2 `mod_muc.lua` → `modules/muc/mod_muc.lua`
 **Purpose:** MUC component loader and room lifecycle management.
 **Key deviations from upstream:**
 - **Custom unregister IQ hook:** Added `iq-set/bare/xmpp:vnctalk:unregister:query` → `handle_unregister_iq`. This exposes a VNCtalk-specific room-unregistration endpoint.
 - **Debug helper:** Added `dumpTable(t, depth)` utility function.
 - **Room defaults:** `muc_room_default_public` defaults to `false` (rooms are hidden by default).
 ---
 ### 1.3 `mod_muc_mam.lua` → `modules/mod_muc_mam.lua`
 **Purpose:** MUC Message Archive Management.
 **Key deviations from upstream:**
 - **`with` filter hardcoded to `message<groupchat`:** The archive query and history loader both set `with = "message<groupchat"`, meaning only groupchat messages are stored/retrieved; presence stanzas are ignored unless `muc_log_presences` is enabled.
 - **Presence archiving option:** If `muc_log_presences` is true, join/leave presences are archived with synthetic `with` values (`presence` / `presence<unavailable`).
 - **MUC history from archive:** The `muc-get-history` hook loads history from the archive backend when the in-memory `_history` buffer is insufficient, respecting `max_history_messages`.
 - **Stanza-id stripping before broadcast:** A `muc-broadcast-message` hook (priority 1) strips any `stanza-id` tags that claim to be from the room JID before the stanza is broadcast.
 - **Occupant affiliation injection:** When `whois == "anyone"`, archived messages include an `<x xmlns="http://jabber.org/protocol/muc#user">` item with the sender's affiliation and role.
 ---
 ### 1.4 `mod_muc_unique.lua` → `modules/mod_muc_unique.lua`
 **Purpose:** XEP-0307 Unique Room Names.
 **Key deviations from upstream:**
 - **Bare-JID request returns error:** Added `handle_iq_tobare` that replies with `item-not-found` for IQ-get requests sent to a bare JID, rather than generating a unique name. Unique names are only served for host-targeted requests.
 ---
 ### 1.5 `moduleapi.lua` → `core/moduleapi.lua`
 **Purpose:** Module API base.
 **Key deviations from upstream:**
 - **Added `open_host_store`:** New method `api:open_host_store(host, name, store_type)` allows a module to open a data store on behalf of a different host. This is heavily used by MUC FCM modules to read user private data / vCards from the main virtual host while running inside the MUC component.
 ---
 ### 1.6 `muc.lib.lua` → `modules/muc/muc.lib.lua`
 **Purpose:** MUC room implementation (the largest patch).
 **Key deviations from upstream:**
 - **Offline-affiliate broadcast (`broadcast` method):** After broadcasting to all online occupants, the method iterates over `_affiliations` and sends the stanza to any affiliated JIDs that are **not** currently in the room, **provided their domain is not hosted locally**. This enables federation/remote-user delivery.
 - **`publicise_occupant_status` skip for unavailable:** When an occupant's role becomes `nil` (they left), the code logs `"skipping unavailable presence"` and does **not** route an unavailable presence to the leaving user themselves. This changes the standard XEP-0045 self-presence delivery.
 - **Debug helpers:** Added `dumpTable` and `table_clone`.
 ---
 ### 1.7 `hidden.lib.lua` → `modules/muc/hidden.lib.lua`
 **Purpose:** Room visibility (public/hidden).
 **Key deviations from upstream:**
 - **Restricted public rooms:** If `muc_room_allow_public` is `false` (default in VNCtalk config), the public-room config option is hidden from non-admins, and only admins may create public rooms.
 ---
 ### 1.8 `register.lib.lua` → `modules/muc/register.lib.lua`
 **Purpose:** MUC room nickname registration.
 **Key deviations from upstream:**
 - **VNCtalk unregister handler (`handle_unregister_iq`):** Fires `vnc-muc-kick` event and unconditionally removes the user's affiliation from `_affiliations`, bypassing normal affiliation-change logic. This is used for VNCtalk-specific account deletion/room cleanup.
 ---
 ### 1.9 `mod_carbons.lua` → `modules/mod_carbons.lua`
 **Purpose:** XEP-0280 Message Carbons.
 **Key deviations from upstream:**
 - **`vnc-rest-message` hook:** Added `module:hook("vnc-rest-message", c2s_message_handler, -0.5)`. Messages injected via the REST endpoint are carbon-copied to the user's other resources just like locally-sent messages.
 ---
 ### 1.10 `mod_admin_telnet.lua` → `modules/mod_admin_telnet.lua`
 **Purpose:** Admin telnet console.
 **Key deviations from upstream:**
 - **Listens on all interfaces:** Changed `interface` from `"127.0.0.1"` to `"*"`. The healthcheck script (`healthcheck.sh`) relies on connecting to `127.0.0.1:5582`, but the console is now bound to `0.0.0.0`.
 ---
 ### 1.11 `portmanager.lua` → `core/portmanager.lua`
 **Purpose:** Network port management.
 **Key deviations from upstream:**
 - **Respects `network_default_read_size` for socket mode:** `local default_mode = config.get("*", "network_default_read_size") or 4096;` instead of a hardcoded `4096`. The VNCtalk config sets this to `8192` to support larger stanzas (Jitsi/file transfers).
 ---
 ## 2. Custom Modules (`vnctalk/`)
 ### 2.1 Authentication
 #### `mod_auth_http_async`
 - **HTTP-based authentication.** Replaces Prosody's internal password database with an async HTTP call to `http_auth_url`.
 - Sends a `Basic` auth header with `base64(username@host:password)`.
 - If `util.async` is unavailable, falls back to synchronous `socket.http` / `ssl.https`.
 - `user_exists` always returns `true`; `set_password` / `create_user` / `delete_user` are no-ops.
 ---
 ### 2.2 Push Notifications (FCM)
 #### `mod_vnc_fcm`
 - **FCM push for 1:1 messages.** Hooks on `message/bare`, `pre-message/bare/full`, and `vnc-rest-message`.
 - Reads FCM tokens from private storage (`documents:stanza:io:json` → `fcm` element) and from a map store (`fcmtoken`).
 - Supports iOS and Android tokens; iOS gets a notification payload with sound, Android gets data-only.
 - Handles VNCtalk-specific extensions: `vncTalkConference`, `whiteboard`, `attachment`, `read` signals, Jitsi URL/room.
 - Removes invalid FCM tokens (`NotRegistered`, `InvalidRegistration`, etc.) from user private data automatically.
 - **Inactive-device tracking:** Uses `csi-client-active/inactive` hooks to avoid pushing to devices that are online but inactive.
 #### `mod_vnc_fcm_hin`
 - Variant of `mod_vnc_fcm` with HIN (German health network) specific modifications.
 #### `mod_vnc_muc_fcm` / `mod_vnc_muc_fcm_hin`
 - **FCM push for MUC messages.** Loaded on the MUC component.
 - Opens stores against `storage_host` (the main virtual host) using `module:open_host_store`.
 - On each groupchat message, iterates over room affiliations and pushes to offline/non-occupant members.
 ---
 ### 2.3 MUC Extensions
 #### `mod_vnc_muc_automember`
 - Automatically grants `member` affiliation to anyone who receives a MUC invite, if they were previously unaffiliated.
 #### `mod_vnc_muc_hook`
 - Sends a XMPP message notification (with `http://vnc.biz/xmpp/muc#hook` namespace) to online users who are affiliated with a room but not currently joined, when an "important" message (has non-empty body) is broadcast.
 - Optionally sends a mediated invite instead of a plain notification (`muc_notification_invite`).
 #### `mod_vnc_muc_data`
 - Adds a `muc#roomconfig_vdata` config field and `muc#roominfo_vdata` disco info field.
 - On config change, broadcasts a groupchat message with `<x xmlns='xmpp:vnctalk:update'/>` containing JSON-encoded affiliations and room data.
 #### `mod_vnc_e2ehints`
 - Adds a `muc#roomconfig_e2e` boolean field and `muc#roominfo_e2e` disco info field for end-to-end encryption hints.
 #### `mod_vnc_remotemucstore`
 - Archives groupchat messages from **remote** MUCs (federation) into a local archive (`muc_remote`) so users can query history even for rooms not hosted locally.
 - Stores MUC presence metadata (real JID mapping, subject, nick) in a map store.
 - Prevents further processing of messages addressed to bare JIDs from remote MUCs (so they don't create offline message spam).
 #### `mod_vnc_remotemucinvite`
 - Archives mediated MUC invitations sent to remote users in a store (`muc_remote_inv`).
 #### `mod_vnc_track_kicks`
 - Tracks kick/ban events in MUC rooms (lightweight event logger).
 ---
 ### 2.4 vCard & Avatar
 #### `mod_vnc_vcard_avatar`
 - On vCard update (IQ-set to self), extracts the PHOTO binval, decodes it, and uploads it via HTTP PUT to `avatar_upload_url`.
 - Uses Basic auth if `avatar_upload_user` / `avatar_upload_pass` are configured.
 - Stores an `avatarupdate` timestamp in a map store.
 #### `mod_vnc_vcard_fallback`
 - Intercepts vCard IQ-get requests.
 - If the user has no vCard on file, auto-generates one from the username (dot-separated usernames become `FIRSTNAME LASTNAME`).
 - Adds `ORGNAME` if `default_vcard_orgname` is configured.
 ---
 ### 2.5 Messaging Extensions
 #### `mod_vnc_timestamp`
 - Adds a custom `<stamp xmlns='xmpp:vnctalk:stamp'/>` tag to incoming chat/groupchat messages that have a body.
 - Sends an IQ-result back to the sender containing the timestamp and original stanza ID.
 #### `mod_vnc_receipts`
 - Archives XEP-0184 delivery receipts (`<received xmlns='urn:xmpp:receipts'/>`) in an archive store (`receipts`).
 #### `mod_vnc_lastactivity`
 - Extends XEP-0012 last activity with avatar hash caching.
 - Caches SHA1 of the user's vCard PHOTO in memory (`avt_hash_table`).
 - Stores/retrieves remote user activity and avatar updates in map stores.
 #### `mod_vnc_broadcast`
 - Implements a `vnc_broadcast` component.
 - Accepts messages with `<vncTalkBroadcast xmlns='xmpp:vnctalk'>` and fans them out to:
  - Explicit `to` JIDs
  - Roster groups (via `roster_manager.load_roster`)
  - MUC room affiliations (if a `to` JID is a MUC)
 ---
 ### 2.6 HTTP / REST
 #### `mod_http_rest`
 - Exposes `POST /rest` on the HTTP server.
 - Accepts `Content-Type: text/xml` bodies, parses them as XMPP stanzas, and injects them into the server via `module:fire_event("vnc-rest-message", …)`.
 - Returns `201` on success, `415` for wrong content type, `422` for unparseable body.
 #### `mod_http_upload_external`
 - Delegates HTTP file upload to an external PHP endpoint (`share.php`).
 - Generates signed URLs using `http_upload_external_secret`.
 ---
 ### 2.7 Utility Modules
 | Module | Purpose |
 |--------|---------|
 | `mod_alias` | Allows users to have alias JIDs |
 | `mod_roster_command` | Ad-hoc commands for roster management |
 | `mod_s2s_keepalive` | Keepalive pings for S2S connections (Jitsi compatibility) |
 | `mod_smacks` / `mod_smacks_offline` | Stream Management (XEP-0198) with offline queue support |
 | `mod_carbons_copies` | Helper for carbons routing |
 | `mod_log_slow_events` | Logs events exceeding `log_slow_events_threshold` |
 | `mod_discoitems` | Manual override of disco items for a host |
 | `mod_filter_chatstates` | Drops chat-state notifications under certain conditions |
 | `mod_idlecompat` | Compatibility shim for idle detection |
 | `mod_http_altconnect` | Alternative connection methods discovery |
 | `mod_http_index` | Static HTTP index page |
 | `mod_webpresence` | Publish presence as web images/icons |
 | `mod_auto_accept_subscriptions` | Auto-accept presence subscriptions |
 | `mod_vcard_muc` | vCard support for MUC rooms |
 | `mod_vnc_delfile` | File deletion command via XMPP |
 ---
 ## 3. Configuration-Driven Behaviour
 Several behaviours are not hard-coded in Lua but emerge from `config/prosody.cfg.lua.template`:
 | Config Option | Effect |
 |---------------|--------|
 | `authentication = "http_async"` | All client auth goes to `hybridaAuthUrl` |
 | `default_archive_policy = "roster"` | MAM archives only roster contacts by default |
 | `muc_log_by_default = true` / `muc_log_all_rooms = true` | All MUC messages archived |
 | `c2s_require_encryption = true` | Plaintext C2S rejected |
 | `keepalive_servers = { "${DEFAULT_JITSI_CONFERENCE}" }` | S2S keepalive pings sent to Jitsi |
 | `component_secret = "…"` | Fixed MUC component secret (not randomly generated) |
 ---
 ## 4. Healthcheck & Runtime Quirks
 - `healthcheck.sh` exits **2** (not 1) when the TLS cert in `/etc/tls-update/tls.crt` differs from the loaded one. Orchestrators must treat exit code 2 as a restart signal.
 - `startup-sidecar.sh` runs a Node `http-server` on port 8080 for static files; this is **not** the XMPP server.
 - `startup.sh` generates fallback certs from base64 defaults if `prosodySSLkey/cert` env vars are missing.

 # VNCtalk Prosody Verification Test Suite
 This directory contains an integration-test suite that verifies whether a running XMPP server conforms to the VNCtalk Prosody behaviour requirements.
 ## Prerequisites
 You need **Python 3.10+** with the `venv` module.
 ### 1. Create the virtualenv
 Create it inside the repo (recommended) so it is isolated and reproducible:
 ```bash
 cd /path/to/vnctalk-prosody
 python3 -m venv tests/venv
 ```
 Or use a hidden `.venv` at repo root:
 ```bash
 python3 -m venv .venv
 ```
 ### 2. Activate the virtualenv
 **Linux / macOS:**
 ```bash
 source tests/venv/bin/activate
 ```
 **Windows (PowerShell):**
 ```powershell
 tests/venv/Scripts/Activate.ps1
 ```
 **Windows (cmd.exe):**
 ```cmd
 tests/venv/Scripts/activate.bat
 ```
 ### 3. Install dependencies
 ```bash
 pip install slixmpp pytest pytest-asyncio aiohttp
 ```
 The dependencies are also captured in `tests/pytest.ini` (config only). If you want to pin versions for CI, create a `tests/requirements.txt` and run `pip install -r tests/requirements.txt`.
 ### 4. Verify the installation
 ```bash
 pytest tests/ --collect-only -c tests/pytest.ini
 ```
 You should see 27 tests collected. If the collection fails with an `asyncio` error, make sure you are passing `-c tests/pytest.ini` (it sets `asyncio_mode = auto`).
 ## Configuration
 Tests are configured via **environment variables** or **CLI options**.
 ### Environment variables
 | Variable | Default | Description |
 |----------|---------|-------------|
 | `XMPP_HOST` | `localhost` | C2S hostname |
 | `XMPP_PORT` | `5222` | C2S port |
 | `XMPP_JID` | *(empty)* | Test account JID |
 | `XMPP_PASSWORD` | *(empty)* | Test account password |
 | `XMPP_DOMAIN` | `example.com` | XMPP domain |
 | `BOSH_URL` | *(empty)* | BOSH endpoint URL |
 | `WS_URL` | *(empty)* | WebSocket endpoint URL |
 | `REST_URL` | *(empty)* | `mod_http_rest` URL |
 | `MUC_DOMAIN` | *(empty)* | MUC component domain |
 | `ADMIN_TELNET_HOST` | `127.0.0.1` | Admin telnet host |
 | `ADMIN_TELNET_PORT` | `5582` | Admin telnet port |
 ### CLI options
 All env vars can be overridden on the command line:
 ```bash
 pytest tests/ \
  --xmpp-host=192.168.1.10 \
  --xmpp-jid=user@example.com \
  --xmpp-password=secret \
  --xmpp-domain=example.com \
  --muc-domain=conference.example.com \
  --bosh-url=http://192.168.1.10:5280/http-bind \
  --ws-url=ws://192.168.1.10:5280/xmpp-websocket \
  --rest-url=http://192.168.1.10:5280/rest
 ```
 ## Running
 The test suite includes a `pytest.ini` with `asyncio_mode = auto`. Run from the repo root or point to the config:
 ### Run all tests
 ```bash
 pytest tests/ -v -c tests/pytest.ini
 ```
 ### Skip live-connection tests (dry-run infrastructure checks only)
 ```bash
 pytest tests/ -v --skip-live -c tests/pytest.ini
 ```
 ### Run a specific test file
 ```bash
 pytest tests/test_01_core.py -v -c tests/pytest.ini
 ```
 ### Run with a running Prosody container
 If you built the Docker image and started it with `test.sh`, expose the ports and run:
 ```bash
 export XMPP_HOST=127.0.0.1
 export XMPP_JID=admin@example.com
 export XMPP_PASSWORD=<the-password-from-your-auth-backend>
 export XMPP_DOMAIN=example.com
 export MUC_DOMAIN=conference.example.com
 export BOSH_URL=http://127.0.0.1:5280/http-bind
 export WS_URL=ws://127.0.0.1:5280/xmpp-websocket
 export REST_URL=http://127.0.0.1:5280/rest
 pytest tests/ -v
 ```
 ## Test Coverage
 | File | What it checks |
 |------|----------------|
 | `test_01_core.py` | C2S auth, disco features (MAM, carbons), BOSH/WebSocket reachability, REST injection |
 | `test_02_muc.py` | MUC disco, room creation, MUC MAM query, auto-member on invite, vdata disco |
 | `test_03_vnctalk.py` | vCard fallback, avatar upload trigger, timestamp stamps, receipts, broadcast component |
 | `test_04_infra.py` | Admin telnet banner, healthcheck exit-code contract, port reachability |
 ## Notes
 - Tests that require a live XMPP account are **skipped** automatically if `--xmpp-jid` or `--xmpp-password` are empty (or if `--skip-live` is used).
 - MUC tests create temporary rooms. If the test account is not allowed to create rooms, those tests will skip or fail.
 - The REST injection test sends a dummy stanza; a `201` or `422` response is considered acceptable ( Prosody may reject unroutable stanzas with 422).
 - The healthcheck test inspects the script source for the required `exit 2` semantics rather than executing it inside the container.
