Summary

Local staging environment on code-server for testing PRs before merge. Enables:

  • CLI-based testing with isolated config/sessions
  • Gateway validation without external channels
  • Quick PR testing workflow via ./test-pr.sh <pr-number>

Changes

Infrastructure

  • NANOBOT_CONFIG environment variable support — specify custom config file path
  • OAuth credentials migration — extract api_key from oauthCredentials.access_token structure
  • test-pr.sh helper script — automate PR checkout, install, and test

Staging Setup

  • Directory: /config/workspace/.nanobot-staging/
  • Config: channels disabled, shared OAuth with production
  • Sessions: isolated from production ({workspace}/sessions/)
  • Workspace: separate tool operations workspace

Testing

All components tested:

  • ✅ CLI agent with staging config
  • ✅ Gateway startup validation
  • ✅ PR #31 tested successfully (hidden message signatures feature works)
  • ✅ Helper script tested with PR #31

Usage

# Quick PR test
./test-pr.sh 31 "test message"

# Manual test
NANOBOT_CONFIG=/config/workspace/.nanobot-staging/config.json \
  nanobot agent -m "test message"

Files Changed

  • nanobot/config/loader.py — NANOBOT_CONFIG support + OAuth migration
  • test-pr.sh — PR testing automation script

Add support for NANOBOT_CONFIG environment variable 7bcd6c5349 
Modify get_config_path() to check NANOBOT_CONFIG env var first before
falling back to ~/.nanobot/config.json. This allows staging/custom
setups to use a different config file without modifying code.

Fix: Extract api_key from oauthCredentials in config migration 0de186071b 
Added logic to _migrate_config() to automatically populate the api_key field
from oauthCredentials.access_token when present. This allows configs that
store OAuth tokens in the oauthCredentials structure to work correctly.

PR Review: Add local staging environment for PR testing

Overview

Clean, focused PR with three logical changes:

  1. NANOBOT_CONFIG env var for custom config path
  2. OAuth credentials migration in _migrate_config
  3. test-pr.sh helper script

Findings

1. NANOBOT_CONFIG env var support — looks good

The implementation is clean and minimal. Both load_config and save_config use get_config_path() so they stay consistent. One note: _get_oauth_store_dir() still hardcodes Path.home() / ".nanobot" regardless of NANOBOT_CONFIG. This means OAuth creds are always read from ~/.nanobot/ even with a custom config path. The PR description says "shared OAuth with production" so this seems intentional, but it's an implicit coupling worth being aware of.

2. OAuth credentials migration — functional, but has a gap

The migration extracts access_token from oauthCredentials into api_key, but leaves the oauthCredentials dict in place. After migration, the token exists in two locations in the config dict. Consider cleaning up the source:

if access_token and not provider_config.get("api_key"):
    provider_config["api_key"] = access_token
    del provider_config["oauthCredentials"]  # clean up migrated data

Also, provider_name is unused in the loop — should be _ per convention.

3. test-pr.sh — works but has rough edges

Issue Severity Detail
Branch collision Medium git fetch wylab "pull/$PR_NUM/head:pr-$PR_NUM" will fail if pr-$PR_NUM already exists from a previous test. Add git branch -D "pr-$PR_NUM" 2>/dev/null before fetch, or use + refspec (+pull/$PR_NUM/head:pr-$PR_NUM)
Hardcoded paths Low /config/workspace/... — not portable, but clearly a dev-only tool
No cleanup Low Branches accumulate over time

4. No tests added

Neither the env var support nor the migration logic have test coverage. _migrate_config has zero test coverage in the existing test suite. At minimum:

  • Test get_config_path() with/without NANOBOT_CONFIG set
  • Test _migrate_config with oauthCredentials present/absent/already-migrated

Summary

Aspect Verdict
Correctness ✅ Code does what it says
Security ✅ No new attack surface
Tests ⚠️ Migration logic untested
Script robustness ⚠️ Branch collision on re-run

Recommendation: Mergeable as-is for a dev tooling PR, but the branch collision in test-pr.sh will bite on second use. The missing tests are a risk for the migration logic in loader.py.

PR Review (Round 2): Post-feedback assessment

The previous review identified 4 issues. All have been addressed in follow-up commits:

Original Issue Fix Commit Status
oauthCredentials left after migration 153b08f — del provider_config["oauthCredentials"] ✅ Fixed
provider_name unused variable 153b08f — changed to _ ✅ Fixed
Branch collision in test-pr.sh 1b920d7 — + refspec for force-update ✅ Fixed
No test coverage a3fe901 — 7 tests added ✅ Fixed

Remaining Findings

1. Edge case in migration: oauthCredentials persists when api_key already set

When both api_key and oauthCredentials exist (the "already migrated" case), oauthCredentials is intentionally kept (line 104: migration only fires when api_key is absent). This means stale oauthCredentials data lingers in the config dict.

If the Pydantic schema ever switches to extra='forbid', this leftover field would cause a validation error. Currently harmless, but worth noting. Consider always cleaning up oauthCredentials regardless:

if access_token and not provider_config.get("api_key"):
    provider_config["api_key"] = access_token
# Always clean up oauthCredentials regardless of migration
if "oauthCredentials" in provider_config:
    del provider_config["oauthCredentials"]

Severity: Low — current schema allows extra fields.

2. Test env var isolation uses manual try/finally instead of monkeypatch

Tests manipulate os.environ directly with try/finally cleanup. Using pytest's monkeypatch fixture would be more idiomatic and automatically cleaned up:

def test_get_config_path_with_env_var(monkeypatch):
    monkeypatch.setenv("NANOBOT_CONFIG", "/tmp/test-nanobot-config.json")
    assert get_config_path() == Path("/tmp/test-nanobot-config.json")

Severity: Minor — current approach works, just less idiomatic.

3. save_config writes migrated-away fields back

save_config calls config.model_dump(by_alias=True) which serializes the Pydantic model — this is fine. But if a config was loaded (triggering migration), then saved, the oauthCredentials field is gone from the on-disk config permanently. This is the correct behavior (migration is intentionally one-way), but worth being explicit that running nanobot with NANOBOT_CONFIG pointing to a production config will permanently modify it on save. The staging setup avoids this by using a separate config file.

Severity: Informational — by design, just worth documenting.

Verified

  • ✅ All 7 new tests pass locally
  • ✅ NANOBOT_CONFIG respected by both load_config and save_config via shared get_config_path()
  • ✅ _get_oauth_store_dir() intentionally hardcoded to ~/.nanobot — staging shares production OAuth creds
  • ✅ test-pr.sh + refspec handles re-runs correctly
  • ✅ Migration cleans up oauthCredentials after extraction
  • ✅ Migration preserves api_key when already set (no overwrite)
  • ✅ No security concerns — env var only changes config file path

Verdict

Ready to merge. All review feedback addressed. Remaining items are minor/informational and don't block.
