Summary by CodeRabbit

  • New Features

    • Added support for documented command placeholders, game-mod variable resolution, and environment-variable export.
    • Variable precedence is now clearer: server settings override server variables and defaults, with {game} using the game start code as a fallback.
    • Command substitutions preserve empty values and prevent values containing spaces from splitting arguments.
  • Bug Fixes

    • Preserved configured variable values exactly, including numeric-looking, boolean, empty, and whitespace-containing values.
    • Reset stale server input pipes before starting inactive services while preserving active services.
  • Documentation

    • Documented placeholders, variable precedence, value preservation, safe substitution, and protected port environment variables.

📝 Walkthrough

Walkthrough

The change updates command placeholder resolution, preserves variable values across command and environment handling, adds related tests and documentation, and resets stale systemd stdin FIFOs before server startup.

Changes

Command Variable Resolution

Layer / File(s) Summary
Resolution rules and data contract
internal/app/domain/game.go, internal/app/domain/commands.go, internal/app/domain/server_test.go, README.md
Game-mod variable fields use JSON tags without numeric or boolean conversion. The game server variable overrides Game.StartCode; Game.StartCode remains the fallback. Documentation defines placeholder resolution, precedence, tokenization, and environment export rules.
Resolution and value-handling validation
internal/app/domain/commands_test.go, internal/app/domain/commands_args_test.go, internal/app/grpc/converters_test.go, internal/app/grpc/server_handler_test.go
Tests cover {game} precedence, empty command arguments, verbatim values, JSON parsing, settings precedence, environment handling, and settings persistence during updates.

Systemd stdin FIFO Reset

Layer / File(s) Summary
Startup FIFO reset
internal/processmanager/systemd.go
Start calls resetStdin before the start command. The helper preserves active services, stops active sockets when needed, removes stale FIFOs, ignores missing files, and returns contextual errors.
FIFO reset validation
internal/processmanager/systemd_internal_test.go
A stateful executor test double and tests cover systemd unit states, socket stopping, stale FIFO removal, active-service preservation, uncreated units, and missing FIFOs.

Priority: ⬇️ Low

Estimated code review effort: 3 (Moderate) | ~25 minutes

Change: Bug fix

Merge Risk: 🔵 Low · up to db2f1

A failed socket stop can disrupt stdin for an affected server, while conflicting placeholder documentation can mislead configuration. These bounded issues should be corrected but do not indicate broad operational failure.

Inline comments:
In `@internal/processmanager/systemd.go`:
- Line 345: Update resetStdin around ExecWithWriter to capture and validate both
the returned result and err before removing the FIFO: preserve the wrapped error
path, and return an error for any result other than domain.SuccessResult. Extend
Test_resetStdin with a nonzero-result case verifying the FIFO is not removed.

In `@README.md`:
- Around line 181-182: Align the README placeholder case-handling statement with
newServerReplacer: either document only the original, lowercase, and uppercase
forms, or update replacement to normalize names so mixed-case variants such as
{MaxPlayers} resolve. Keep the documented behavior consistent with the actual
supported behavior.
- Around line 174-191: Update the English and Russian game-configuration
documentation to explain that the game mod’s `game` variable overrides the
built-in `{game}` placeholder, while the game start code is used as the
fallback; align the precedence wording with the README’s “Game mod variables”
section.

| `{game}` | Game start code; a mod variable named `game` wins (see below)
| `{node_work_path}`, `{node_tools_path}` | Daemon `work_path` and its `tools` subdirectory
| `{command}` | Wrapper templates only: the tokens of the server command

### Game mod variables

Every variable of the game mod (the `vars` list in the games catalogue) is a
placeholder too, in any letter case: `{maxplayers}` also matches
`{MAXPLAYERS}`. The value is resolved in this order, the last one wins:

1. the variable default from the game mod;
2. the server variables (`vars` on the admin server page);
3. the server settings (the server settings page).

A built-in placeholder wins over a variable of the same name, except `{game}`:
the catalogue defines it as a mod variable (Quake 2 starts with
`+set game {game}` and a variable `game=baseq2`), so the variable wins and the
game start code is only the fallback.

Update the linked website documentation for {game} precedence.

The English and Russian game-configuration pages still state that built-in shortcodes take precedence and describe {game} only as the game start code. Update en/gameap_configure/games.md and ru/gameap_configure/games.md to document the game variable override and start-code fallback.
