[P0] New e2e test spies on console.info, but the code under test logs via params.logReload.info (not console.info)
In createGatewayReloadHandlers the binding message is emitted with params.logReload.info("agent bindings reloaded"), so overriding console.info won’t observe it unless logReload.info is actually console.info in your test harness. As written, this test can be a false negative/positive depending on how startGatewayServer wires logging.
Consider asserting on the injected logger (e.g. mock logReload.info) or capturing whatever logging sink startGatewayServer uses.

| ### Scenario 1: Regular Upstream Sync (Weekly/Bi-weekly) | ||
|
|
||
| When upstream has new commits and you want to pull them in: | ||
|
|
||
| 1. **Phase 0**: Check if main is clean (should be) | ||
| 2. **Phase 1**: Merge upstream/main → main (fast-forward) | ||
| 3. **Phase 2**: Merge main → DEV | ||
| 4. **Phase 3**: Merge DEV → PRD | ||
| 5. **Time**: ~5-10 minutes |

There was a problem hiding this comment.
The resetDirectoryCache() call does not actually clear any cache related to agent bindings. This function clears the cache for channel directory entries (like group names in Discord/Slack channels), not routing bindings.
Agent bindings are read directly from the config object passed to the hot-reload handler (nextConfig parameter), which already bypasses the 200ms config cache by reading a fresh snapshot from disk. The hot-reload mechanism is working correctly, but this specific handler implementation appears to be based on a misunderstanding of what resetDirectoryCache() does.
While the hot-reload will work correctly (bindings will be read from nextConfig), the resetDirectoryCache() call here is unnecessary and misleading since it suggests bindings use this cache when they don't.

There was a problem hiding this comment.
This change removes the trigger for building Docker images on pushes to the main branch, meaning Docker images will now only be built for tagged releases (starting with "v"). This is a significant behavioral change that is unrelated to the stated purpose of this PR (adding hot-reload for agent bindings).
This change should either be:
- Removed from this PR and submitted separately with its own justification
- Explained in the PR description why it's included
Based on the PR title and description, this appears to be an unintentional inclusion or a change from a different branch.

| # Fork Sync Workflow | ||
|
|
||
| Comprehensive skill for managing the OpenClaw fork workflow, syncing with upstream, and updating all development branches. | ||
|
|
||
| ## Critical Principle: Main is a Clean Mirror | ||
|
|
||
| **IMPORTANT**: The `main` branch must ALWAYS be a clean mirror of `upstream/main`. It should NEVER contain custom commits. | ||
|
|
||
| ### Workflow for Custom Changes | ||
|
|
||
| When `main` has diverged from upstream (contains custom commits): | ||
|
|
||
| 1. **Verify custom commits are on DEV/PRD**: Check that all custom work exists on development branches | ||
| 2. **Reset main to upstream**: `git reset --hard upstream/main` | ||
| 3. **Force push main**: `git push --force-with-lease origin main` | ||
| 4. **Custom work remains safe**: All custom commits stay on DEV/PRD/feature branches | ||
|
|
||
| ### Detection and Resolution | ||
|
|
||
| ```bash | ||
| # Check if main has diverged | ||
| git fetch upstream | ||
| git log --oneline upstream/main..main | ||
|
|
||
| # If output shows commits (main has diverged): | ||
| # 1. Verify commits are on DEV/PRD | ||
| git log --oneline DEV | head -20 | ||
| git log --oneline PRD | head -20 | ||
|
|
||
| # 2. Reset main to upstream | ||
| git checkout main | ||
| git reset --hard upstream/main | ||
| git push --force-with-lease origin main | ||
| ``` | ||
|
|
||
| ## Branch Structure | ||
|
|
||
| This fork maintains a specific branch hierarchy: | ||
|
|
||
| ``` | ||
| upstream/main (source of truth) | ||
| ↓ | ||
| main (clean mirror - NO custom commits) | ||
| ↓ | ||
| DEV (integration branch: main + all custom work) | ||
| ↓ | ||
| PRD (production-ready: mirrors DEV after validation) | ||
| ``` | ||
|
|
||
| ### Branch Purposes | ||
|
|
||
| - **main**: Clean mirror of upstream/main, NEVER contains custom work | ||
| - **DEV**: Integration branch containing all custom features, used for testing | ||
| - **PRD**: Production-ready branch, mirrors DEV after validation | ||
|
|
||
| ## Core Workflow | ||
|
|
||
| ### Phase 0: Clean Main (if needed) | ||
|
|
||
| **Goal**: Ensure main is a clean mirror of upstream | ||
|
|
||
| ```bash | ||
| # Check if main has diverged | ||
| git checkout main | ||
| git fetch upstream | ||
| git log --oneline upstream/main..main | ||
|
|
||
| # If commits shown, main has diverged - fix it: | ||
| # 1. Verify custom commits exist on DEV/PRD | ||
| git log --oneline DEV | grep "CustomCommit" | ||
| git log --oneline PRD | grep "CustomCommit" | ||
|
|
||
| # 2. Reset main to upstream | ||
| git reset --hard upstream/main | ||
| git push --force-with-lease origin main | ||
| ``` | ||
|
|
||
| **When to run**: Any time main has custom commits (detected by divergence check) | ||
|
|
||
| ### Phase 1: Sync Main with Upstream | ||
|
|
||
| **Goal**: Update local main to match upstream/main | ||
|
|
||
| ```bash | ||
| # Fetch latest from upstream | ||
| git fetch upstream | ||
|
|
||
| # Switch to main (should already be clean) | ||
| git checkout main | ||
|
|
||
| # Fast-forward merge upstream changes (should succeed now) | ||
| git merge --ff-only upstream/main | ||
|
|
||
| # Push to fork | ||
| git push origin main | ||
| ``` | ||
|
|
||
| **Expected**: Fast-forward merge, no conflicts (since main is clean mirror) | ||
|
|
||
| ### Phase 2: Update DEV Branch | ||
|
|
||
| **Goal**: Merge updated main into DEV (bringing in upstream changes) | ||
|
|
||
| ```bash | ||
| git checkout DEV | ||
|
|
||
| # Merge updated main | ||
| git merge main -m "Merge upstream changes from main" | ||
|
|
||
| # Resolve conflicts if any | ||
| # Push to origin | ||
| git push origin DEV | ||
| ``` | ||
|
|
||
| **Expected**: Clean merge or minor conflicts (DEV has custom commits + upstream changes) | ||
|
|
||
| ### Phase 3: Update PRD Branch | ||
|
|
||
| **Goal**: Sync PRD with DEV (after validation) | ||
|
|
||
| ```bash | ||
| git checkout PRD | ||
|
|
||
| # Merge updated DEV | ||
| git merge DEV -m "Sync PRD with DEV" | ||
|
|
||
| # Push to origin | ||
| git push origin PRD | ||
| ``` | ||
|
|
||
| **Expected**: Clean merge, PRD mirrors DEV | ||
|
|
||
| ## Safety Checks | ||
|
|
||
| ### Pre-Sync Checklist | ||
|
|
||
| Before starting the sync workflow: | ||
|
|
||
| - [ ] Working directory is clean (`git status`) | ||
| - [ ] No uncommitted changes that could conflict | ||
| - [ ] Upstream remote is configured (`git remote -v | grep upstream`) | ||
| - [ ] Latest upstream fetched (`git fetch upstream`) | ||
| - [ ] Main is clean mirror (no divergence from upstream) | ||
|
|
||
| ### Verification Commands | ||
|
|
||
| After completing sync: | ||
|
|
||
| ```bash | ||
| # Verify main matches upstream | ||
| git log --oneline main..upstream/main # Should be empty | ||
|
|
||
| # Verify branch relationships | ||
| git log --oneline --graph --all --decorate -20 | ||
|
|
||
| # Verify DEV contains main's commits | ||
| git merge-base --is-ancestor main DEV && echo "✓ DEV contains main" || echo "✗ DEV missing main commits" | ||
|
|
||
| # Verify PRD contains DEV's commits | ||
| git merge-base --is-ancestor DEV PRD && echo "✓ PRD contains DEV" || echo "✗ PRD missing DEV commits" | ||
| ``` | ||
|
|
||
| ### Post-Sync Checklist | ||
|
|
||
| - [ ] `main` matches `upstream/main` (no divergence) | ||
| - [ ] `main` pushed to `origin/main` | ||
| - [ ] `DEV` merged main successfully | ||
| - [ ] `PRD` merged DEV successfully | ||
| - [ ] All branches pushed to remote | ||
| - [ ] Docker workflows still functional (images building successfully) | ||
|
|
||
| ## Conflict Resolution | ||
|
|
||
| ### Main Has Custom Commits | ||
|
|
||
| **Problem**: `git merge --ff-only upstream/main` fails with "Not possible to fast-forward" | ||
|
|
||
| **Root Cause**: Main contains custom commits (violates clean mirror principle) | ||
|
|
||
| **Solution**: | ||
| 1. Verify custom commits exist on DEV/PRD: `git log --oneline DEV | head` | ||
| 2. Reset main to upstream: `git reset --hard upstream/main` | ||
| 3. Force push: `git push --force-with-lease origin main` | ||
| 4. Continue normal workflow (merge main → DEV → PRD) | ||
|
|
||
| ### Merge Conflicts in DEV | ||
|
|
||
| If conflicts occur when merging main into DEV: | ||
|
|
||
| 1. **Identify conflicts**: `git status` shows conflicted files | ||
| 2. **Common conflict areas**: | ||
| - Docker configurations (if upstream changed docker-compose.yml) | ||
| - Workflow files (if upstream changed .github/workflows/*) | ||
| - Core files modified by both upstream and custom work | ||
|
|
||
| 3. **Resolve manually**: | ||
| - Keep custom Docker configurations from DEV | ||
| - Integrate upstream improvements | ||
| - Test after resolving | ||
|
|
||
| 4. **Complete merge**: | ||
| ```bash | ||
| git add <resolved-files> | ||
| git commit -m "Merge upstream changes, resolve conflicts" | ||
| git push origin DEV | ||
| ``` | ||
|
|
||
| ### Abort/Rollback | ||
|
|
||
| If issues occur during merge: | ||
|
|
||
| ```bash | ||
| # Abort current merge | ||
| git merge --abort | ||
|
|
||
| # Reset to previous state | ||
| git reflog # Find previous commit | ||
| git reset --hard HEAD@{1} | ||
|
|
||
| # Or restore from remote | ||
| git reset --hard origin/<branch-name> | ||
| ``` | ||
|
|
||
| ## Common Scenarios | ||
|
|
||
| ### Scenario 1: Regular Upstream Sync (Weekly/Bi-weekly) | ||
|
|
||
| When upstream has new commits and you want to pull them in: | ||
|
|
||
| 1. **Phase 0**: Check if main is clean (should be) | ||
| 2. **Phase 1**: Merge upstream/main → main (fast-forward) | ||
| 3. **Phase 2**: Merge main → DEV | ||
| 4. **Phase 3**: Merge DEV → PRD | ||
| 5. **Time**: ~5-10 minutes | ||
|
|
||
| ### Scenario 2: Main Has Diverged | ||
|
|
||
| When main accidentally contains custom commits: | ||
|
|
||
| 1. **Phase 0**: Verify commits on DEV/PRD, reset main to upstream | ||
| 2. Continue with normal workflow | ||
| 3. **Time**: ~2-3 minutes extra | ||
|
|
||
| ### Scenario 3: Emergency Hotfix from Upstream | ||
|
|
||
| When upstream has a critical fix you need immediately: | ||
|
|
||
| 1. Sync main (fast-forward) | ||
| 2. Cherry-pick to DEV if urgent: `git cherry-pick <commit-sha>` | ||
| 3. Or run full workflow if you have time | ||
|
|
||
| ## Quick Sync Script | ||
|
|
||
| For routine syncs (assumes main is already clean): | ||
|
|
||
| ```bash | ||
| #!/bin/bash | ||
| # Quick sync script | ||
|
|
||
| set -e # Exit on error | ||
|
|
||
| echo "🔄 Starting fork sync workflow..." | ||
|
|
||
| # Fetch upstream | ||
| git fetch upstream | ||
|
|
||
| # Phase 1: Sync main | ||
| echo "📥 Phase 1: Syncing main with upstream..." | ||
| git checkout main | ||
| git merge --ff-only upstream/main | ||
| git push origin main | ||
|
|
||
| # Phase 2: Update DEV | ||
| echo "🔧 Phase 2: Updating DEV branch..." | ||
| git checkout DEV | ||
| git merge main -m "Merge upstream changes from main" | ||
| git push origin DEV | ||
|
|
||
| # Phase 3: Update PRD | ||
| echo "🚀 Phase 3: Updating PRD branch..." | ||
| git checkout PRD | ||
| git merge DEV -m "Sync PRD with DEV" | ||
| git push origin PRD | ||
|
|
||
| echo "✅ Fork sync complete!" | ||
| git log --oneline --graph --all --decorate -10 | ||
| ``` | ||
|
|
||
| ## Best Practices | ||
|
|
||
| 1. **Keep main clean**: NEVER commit custom work to main | ||
| 2. **All custom work on DEV**: Commit custom changes to DEV or feature branches | ||
| 3. **Sync regularly**: Weekly or bi-weekly to avoid large merge conflicts | ||
| 4. **Clean working directory**: Always start with `git status` showing clean | ||
| 5. **Review upstream changes**: Use `git log main..upstream/main` before merging | ||
| 6. **Test after sync**: Verify Docker images build successfully | ||
| 7. **DEV before PRD**: Always test in DEV before updating PRD | ||
|
|
||
| ## Troubleshooting | ||
|
|
||
| ### "fatal: Not possible to fast-forward" | ||
|
|
||
| **Cause**: Main has custom commits (diverged from upstream) | ||
|
|
||
| **Fix**: Run Phase 0 (Clean Main) first | ||
|
|
||
| ### "error: Your local changes would be overwritten" | ||
|
|
||
| **Cause**: Uncommitted changes in working directory | ||
|
|
||
| **Fix**: | ||
| ```bash | ||
| git status # Review changes | ||
| git stash # Temporarily save changes | ||
| # Run sync workflow | ||
| git stash pop # Restore changes after sync | ||
| ``` | ||
|
|
||
| ### "Updates were rejected because the remote contains work" | ||
|
|
||
| **Cause**: Remote branch has commits not in local branch | ||
|
|
||
| **Fix**: | ||
| ```bash | ||
| git pull --rebase origin <branch-name> | ||
| # Resolve conflicts if any | ||
| git push origin <branch-name> | ||
| ``` | ||
|

Summary
This PR adds instant hot-reload for agent binding configuration changes, eliminating the 200ms cache delay for Docker container and production deployments where agents need to dynamically switch channel routing without gateway restarts.
Motivation
Current behavior: Agent bindings are dynamically read with a 200ms config cache TTL, causing a delay between config changes and routing updates.
Desired behavior: Instant binding updates when
openclaw.jsonis modified, especially critical for:Changes

This PR extends the gateway hot-reload system to treat
bindingsconfig changes as a hot-reloadable section:config-reload.tsadds a newreload-bindingsaction andreloadBindingsflag inGatewayReloadPlan, andserver-reload-handlers.tshandles that flag by logging and relying on the existingresetDirectoryCache()to invalidate routing lookups. It also updates the Docker release workflow to pass additional apt packages during builds, and adds a new e2e test intended to verify the bindings reload path.Confidence Score: 3/5
console.infowhile the reload handler logs through an injected logger. Workflow changes are straightforward but should be verified in CI for Docker builds.(2/5) Greptile learns from your feedback when you react with thumbs up/down!
