feat: add lox ctx for multi-Miniserver context management - #101
Conversation
…39) Implements context management for multiple Miniserver connections and project-local configurations, similar to `kubectl config use-context`. New commands: - `lox ctx add <name> --host --user --pass` — add a named context - `lox ctx use <name>` (or `lox ctx <name>`) — switch active context - `lox ctx list` — list all contexts (* = active) - `lox ctx current` — show current active context - `lox ctx remove <name>` — remove a context - `lox ctx rename <old> <new>` — rename a context - `lox ctx init` — initialize project-local .lox/ directory - `lox ctx migrate` — convert flat config to 'default' context - `--ctx <name>` global flag — one-off command against a different context Key design: - Backward compatible: existing flat ~/.lox/config.yaml continues to work - Multi-context format uses `active_context` + `contexts` map in config.yaml - Project-local .lox/ directories are auto-discovered (walks up from cwd) - Per-context data directories (~/.lox/contexts/<name>/) for cache and tokens - Resolution order: LOX_CONFIG env → project-local .lox/ → global config - `--ctx` flag overrides context selection Closes #39 https://claude.ai/code/session_01UcWgojevxixQVy3Zd9FSkB

Review: lox ctx — Multi-Miniserver Context Management
Good feature concept — the kubectl-style context management is the right UX pattern for multi-Miniserver users. However, this PR is not production-ready as-is. There are CI failures, an incomplete migration, missing docs, and several code-level issues that need addressing.
🔴 CI is Failing
- Test (macos-latest): FAILURE
- Test (ubuntu-latest): CANCELLED
- Test (windows-latest): CANCELLED
- Lint and Coverage passed, but the test matrix is broken. This alone blocks merge.
🔴 Incomplete Context-Aware Migration (Token & Scenes)
The PR introduces per-context data isolation (~/.lox/contexts/<name>/) and correctly updates LoxClient::cache_path() to use cfg.cache_dir(). However, token and scene operations still use hardcoded global paths:
TokenStore::load()/save()/path()still useConfig::dir().join("token.json")— these are the methods actually called throughoutsrc/commands/config_cmd.rs(lines 248, 254, 279, 288, 314, 357, 369).Scene::scenes_dir()still usesConfig::dir().join("scenes").
The new context-aware methods (TokenStore::load_for(), save_for(), path_for(), Config::token_path(), Config::scenes_dir()) are all marked #[allow(dead_code)] — they exist but are never called. This means:
- All contexts share the same token → switching contexts won't use the right token
- All contexts share the same scenes directory
This is the most critical functional gap. Either wire up the context-aware methods everywhere, or document this as a known limitation.
🟡 Thread-Safety Issue in Tests
find_local_lox_dir_in_tempdir calls std::env::set_current_dir() which affects all threads in the process. Since cargo test runs tests in parallel by default, this can cause flaky failures in other tests that depend on the working directory. Consider using a test helper that takes a path argument instead, or run this test with #[serial] from the serial_test crate.
🟡 OnceLock for CTX_OVERRIDE is Test-Unfriendly
static CTX_OVERRIDE: OnceLock<Option<String>> can only be set once per process. This means:
- You cannot write tests that exercise different
--ctxflag values - Any test that calls
set_ctx_override()poisons the global state for all subsequent tests
Consider using thread_local! or passing the override through the call chain instead.
🟡 Path Traversal in Context Names
Config::context_data_dir(name) does Self::dir().join("contexts").join(name). If name contains ../, it escapes the contexts directory. For example:
lox ctx add "../../tmp/evil" --host ...→ writes to~/.lox/contexts/../../tmp/evil/
While this is a local CLI tool (low severity), it's worth validating context names — e.g., reject names containing /, \, .., or non-alphanumeric characters beyond - and _.
🟡 ctx_add Auto-Activate Logic
if global.active_context.is_none() || global.contexts.len() == 1 {
global.active_context = Some(name.clone());
}The contexts.len() == 1 check runs after the insert, so this activates the new context if you go from 0→1 contexts. But the is_none() check means it also auto-activates if you somehow have contexts but no active one. This is fine, but the dual condition is confusing — a comment would help, or simplify to just is_none().
🔴 No Documentation Updates
This PR adds a significant new command family (lox ctx) but does not update:
COMMANDS.md— no mention ofctx,--ctxglobal flagREADME.md— no mention of multi-Miniserver supportdocs/commands/configuration.md— noctxsection (this is where it belongs)docs/guides/— no guide for multi-context workflowsCHANGELOG.md— no entryCLAUDE.md/DESIGN.md— architecture docs don't mention contexts or the new config formatdocs/getting-started.md— no mention of project-local.lox/or contexts
For a feature this central to the user experience, docs are essential.
🟡 No Integration Tests for ctx Commands
The 4 new unit tests cover config struct serialization, which is good. But there are no tests for:
ctx_add/ctx_use/ctx_list/ctx_remove/ctx_rename/ctx_migrate/ctx_init- The config resolution order (LOX_CONFIG → local → global → --ctx flag)
- Edge cases: adding duplicate contexts, removing active context, renaming to existing name
- The
Externalsubcommand shortcut (lox ctx home→lox ctx use home)
These are all testable with temp directories and don't require a Miniserver.
🟢 What's Good
- Clean
kubectl-style UX with sensible subcommands - Backward-compatible config format detection (flat vs multi-context)
- Project-local
.lox/with.gitignorethat excludes secrets - JSON output support on all subcommands
lox ctx migratefor smooth upgrade path- Host normalization (auto-prepend
https://) - File permissions set to 0o600 on unix (secrets protection)

Summary
| Area | Status |
|---|---|
| CI | 🔴 Failing (macOS fail, ubuntu/windows cancelled) |
| Core functionality | 🔴 Token/scene paths not wired to contexts |
| Documentation | 🔴 None updated |
| Test coverage | 🟡 Unit tests only, no integration tests |
| Security | 🟡 Context name path traversal |
| Code quality | 🟡 OnceLock testability, thread-unsafe test |
| UX / API design | 🟢 Well-designed |
Recommendation: Fix CI, wire up token/scene context-aware paths, add docs and integration tests, then re-review.
- Wire up context-aware token paths: replace TokenStore::load()/save()/path() with load_for(cfg)/save_for(cfg)/path_for(cfg) in all callers - Wire up context-aware scene paths: replace Scene::load()/list()/scenes_dir() with load_with_config()/list_with_config()/scenes_dir_for() in all callers - Replace OnceLock with RwLock for CTX_OVERRIDE to enable test resettability - Add validate_context_name() to reject path traversal (/, \, ..) - Add find_local_lox_dir_from(path) to avoid thread-unsafe set_current_dir in tests - Simplify ctx_add auto-activate logic to just check is_none() - Add 16 new tests: multi-context loading, ctx override, name validation, path resolution, CLI smoke tests for all ctx subcommands - Update docs: COMMANDS.md, README.md, CHANGELOG.md, CLAUDE.md, docs/commands/configuration.md with ctx usage and examples https://claude.ai/code/session_01A7KveWQqFkmaMhDcTVdFbd Co-authored-by: Claude <noreply@anthropic.com>
