# Server Content Manager

## Current State

`Panel/modules/addonsmanager` is the current home of GSP's Server Content / Add-ons / Workshop work.

The module title has already been moved toward `Server Content Manager`, but the schema and some folder names remain backward-compatible.

Important files:

- `Panel/modules/addonsmanager/module.php`
- `Panel/modules/addonsmanager/addons_manager.php`
- `Panel/modules/addonsmanager/user_addons.php`
- `Panel/modules/addonsmanager/workshop_content.php`
- `Panel/modules/addonsmanager/workshop_action.php`
- `Panel/modules/addonsmanager/server_content_helpers.php`
- `Panel/modules/addonsmanager/server_content_categories.php`

## Database Tables

Known tables used by the module:

- `addons`
- `server_content_workshop`
- `server_content_workshop_catalog`
- `server_content_manifest`
- `server_content_install_history`

## What It Already Does

The module can already represent several content types, including:

- downloads/extracted packages
- post-script driven installs
- workshop-oriented items
- config packs
- future profile-type content

For Workshop items, the current flow lets users enter Workshop IDs or full Steam Workshop URLs and routes the install through module pages, staged manifests, and Panel-bundled scripts executed through existing agent primitives.

## Workshop Phase 1 Flow

1. Admin creates a Server Content template with install method `steam_workshop`.
2. Admin configures the Workshop App ID on the template or relies on the game XML/profile fallback.
3. User opens `Server Content` from the game monitor.
4. User selects the Steam Workshop Mods category.
5. User enters one or more Workshop URLs or numeric IDs.
6. Panel parses IDs, rejects invalid entries, and records rows in `server_content_workshop`.
7. Panel writes a manifest to `{SERVER_HOME}/gsp_server_content/workshop_manifest.json`.
8. Panel syncs the bundled Linux or Cygwin script into `{SERVER_HOME}/gsp_server_content/scripts/workshop/`.
9. Agent executes the script with the manifest path through the existing authenticated `exec` RPC.
10. Script runs SteamCMD, copies Workshop content into the configured target path, copies DayZ/Arma `.bikey` files when applicable, and writes a log under `gsp_server_content`.

The agents are intentionally generic executors in this design. New Workshop business logic should not be added to `Agent-Windows` or `Agent_Linux`; use `remote_writefile`, `exec`, log reads, and normal start/stop/restart primitives instead.

Current script fallback behavior:

- Admin-defined custom scripts are supported when they exist on the agent.
- Missing custom scripts fall back to the bundled generic handler and are logged.
- Default script names such as `generic_steam_workshop_windows_cygwin.sh` are copied from the Panel module source and must not be checked as bare files on the agent.

Current default install paths:

- Generic Steam Workshop content: `{SERVER_ROOT}/workshop/{MOD_FOLDER}`
- DayZ / Arma strategy content: `{SERVER_ROOT}/{MOD_FOLDER}` for root `@<workshop_id>` folder compatibility

Game XML fallback should use the canonical `workshop_support` block:

```xml
<workshop_support>
  <enabled>1</enabled>
  <provider>steam</provider>
  <steam_app_id>107410</steam_app_id>
  <workshop_app_id>107410</workshop_app_id>
  <download_method>steamcmd</download_method>
  <install_strategy>arma_mod_folder</install_strategy>
  <install_path>{SERVER_ROOT}/{MOD_FOLDER}</install_path>
  <startup_param_format>-mod={MOD_LIST}</startup_param_format>
  <mod_separator>;</mod_separator>
  <mod_prefix>@</mod_prefix>
  <copy_keys enabled="1">
    <source_pattern>{MOD_PATH}/keys/*.bikey</source_pattern>
    <target_path>{SERVER_ROOT}/keys</target_path>
  </copy_keys>
</workshop_support>
```

The Panel helper parser reads this block first and only tolerates old direct tags as an internal compatibility fallback.

SteamCMD requirements:

- Linux agents need SteamCMD available at the configured profile/template path, `STEAMCMD_PATH`, `/home/gameserver/steamcmd/steamcmd.sh`, or in `PATH`.
- Windows agents currently use the existing Cygwin agent model and run the bundled Cygwin-compatible shell handler. SteamCMD may be provided as `steamcmd.exe`, `steamcmd.sh`, an explicit configured path, or via `STEAMCMD_PATH`.
- Missing SteamCMD should return a clear error, not a generic script failure.

The legacy `steam_workshop` monitor button is intentionally suppressed so users are not sent to the deprecated standalone module.

## Current User Controls

The `workshop_content.php` page supports:

- direct install by numeric ID or Steam Workshop URL
- installed item list
- enable/disable selected items
- update selected items
- remove selected items
- download selected items without installing immediately
- update all saved Workshop items
- per-item update policy storage
- known/common item catalog sorted by name, install count, published date, last updated, or last installed

Update policies are stored as data for Scheduler/automation:

- `manual`
- `scheduled`
- `update_now`
- `update_and_restart`
- `download_only`
- `install_on_restart`

## Current Limitations

- Workshop and content metadata is still partial.
- Load order is tracked but not yet reorderable through a polished drag-and-drop UI.
- Enable/disable is tracked but not wired into startup-parameter generation yet.
- Async install job progress should be more visible.
- Install strategies are still being broadened and need consistent game-specific rules.
- DayZ/Arma style key-copy is implemented for Phase 1; startup-param behavior still needs a stronger canonical implementation.
- Cache and cleanup policy need a clearer product design.

## Where To Start Reading

1. `Panel/modules/addonsmanager/module.php`
2. `Panel/modules/addonsmanager/addons_manager.php`
3. `Panel/modules/addonsmanager/user_addons.php`
4. `Panel/modules/addonsmanager/workshop_content.php`
5. `Panel/modules/addonsmanager/workshop_action.php`

## Important Concept

This module is the right place for:

- mods
- add-ons
- Workshop content
- config packs
- script-driven installs
- server content manifests
- install history

The old `steam_workshop` module should be treated as a deprecated compatibility layer, not the main future path.

## Validation

Relevant smoke tests:

```bash
php Panel/modules/addonsmanager/tests/workshop_helpers_test.php
php Panel/modules/config_games/tests/validate_server_configs.php
```

`validate_server_configs.php` validates every XML file under `Panel/modules/config_games/server_configs/` against `schema_server_config.xml`.
