Erman HAVUÇandBohdan Triapitsyn fa8fac2590 fix(git): use local-first base ref resolution in getLog, port to VS Code (#1284)
* chore: add .worktrees/ to gitignore for worktree workflow

* fix: resolve remote-tracking base ref in getLog for PR description generation

getLog was calling git log <base>..<head> with a bare branch name that
often doesn't exist locally (e.g. main when only origin/main is present),
causing a fatal 'unknown revision' error and HTTP 500.

Apply the same origin/<base> resolution already used in getRangeDiff and
getRangeFiles: check refs/remotes/origin/<base> first and prefer that ref
if it exists.

Also fix getGitLog in gitApiHttp.ts to read the JSON error body on
failure instead of falling back to response.statusText, so the actual
git error message surfaces in the toast instead of 'Internal Server Error'.

* fix(git): use local-first ref resolution in getLog and port to VS Code

- Replace unconditional origin/<from> preference in getLog() with a
  local-first fallback: prefer the local ref, only use origin/<from>
  when the local ref cannot be resolved, and pass through unchanged
  when neither resolves so git surfaces a meaningful error.
- Extract the logic into an exported resolveBaseRefForLog(from, checkRef)
  helper so it is unit-testable without a real git repo.
- Add service.test.js with 6 cases covering local-wins, origin-fallback,
  neither-exists passthrough, and falsy/empty inputs.
- Port the same local-first resolution to packages/vscode/src/gitService.ts
  getGitLog() to close the cross-runtime parity gap; also handles
  from-only ranges as from..HEAD, matching the web service contract.

* fix(vscode): add missing to-only range branch in getGitLog

When only 'to' is supplied (no 'from'), the web service appends it as a
positional git-log argument. The VS Code port was missing this branch and
silently returned unbounded history instead. Adds the else-if to restore
full cross-runtime parity.

* fix(vscode): surface git log errors

@openchamber/web

GitHub stars GitHub release Discord

Run OpenCode in your browser. Install the CLI, open localhost:3000, done. Works on desktop browsers, tablets, and phones as a PWA.

Full project overview, screenshots, and all features: github.com/btriapitsyn/openchamber

Install

curl -fsSL https://raw.githubusercontent.com/btriapitsyn/openchamber/main/scripts/install.sh | bash

Or install manually: bun add -g @openchamber/web (or npm, pnpm, yarn).

Prerequisites: OpenCode CLI installed, Node.js 20+.

Usage

openchamber                          # Start on port 3000
openchamber --port 8080              # Custom port
openchamber --ui-password secret     # Password-protect UI
openchamber tunnel help              # Tunnel lifecycle commands
openchamber tunnel providers         # Show provider capabilities
openchamber tunnel profile add --provider cloudflare --mode managed-remote --name prod-main --hostname app.example.com --token <token>
openchamber tunnel start --profile prod-main
openchamber tunnel start --provider cloudflare --mode quick --qr
openchamber tunnel start --provider cloudflare --mode managed-local --config ~/.cloudflared/config.yml
openchamber tunnel status --all      # Show tunnel state across instances
openchamber tunnel stop --port 3000  # Stop tunnel only (server stays running)
openchamber logs                     # Follow latest instance logs
OPENCODE_PORT=4096 OPENCODE_SKIP_START=true openchamber                    # Connect to external OpenCode server
OPENCODE_HOST=https://myhost:4096 OPENCODE_SKIP_START=true openchamber  # Connect via custom host/HTTPS
openchamber stop                     # Stop server
openchamber update                   # Update to latest version

Tunnel behavior notes

  • One active tunnel per running OpenChamber instance (port).
  • Starting a different tunnel mode/provider on the same instance replaces the active tunnel.
  • Replacing or stopping a tunnel revokes existing connect links and invalidates remote tunnel sessions.
  • Connect links are one-time tokens; generating a new link revokes the previous unused link.
Connect to external OpenCode server
OPENCODE_PORT=4096 OPENCODE_SKIP_START=true openchamber
OPENCODE_HOST=https://myhost:4096 OPENCODE_SKIP_START=true openchamber
Variable Description
OPENCODE_HOST Full base URL of external server (overrides OPENCODE_PORT)
OPENCODE_PORT Port of external server
OPENCODE_SKIP_START Skip starting embedded OpenCode server
OPENCHAMBER_OPENCODE_HOSTNAME Bind hostname for managed OpenCode server (default: 127.0.0.1, use 0.0.0.0 for LAN/remote access — trusted networks only)
OPENCHAMBER_HOST Bind hostname for the OpenChamber web server (default: 127.0.0.1; use 0.0.0.0 for LAN/remote access — trusted networks only)
OPENCHAMBER_VERBOSE_REQUEST_LOGS Set to true to log every HTTP request; disabled by default to keep user logs small
OPENCHAMBER_SKIP_API_COMPRESSION Set to true to disable gzip compression for /api/* responses
OPENCHAMBER_COMPRESS_API Set to true to force /api/* compression, or false to disable it. Desktop runtime disables API compression by default to reduce local sidecar CPU use
Bind managed OpenCode to LAN / Tailscale
OPENCHAMBER_OPENCODE_HOSTNAME=0.0.0.0 openchamber --port 3000

Security note: binding to 0.0.0.0 exposes the server on all network interfaces — use only on trusted networks and protect with firewall rules or --ui-password.

Optional env vars:

environment:
  UI_PASSWORD: your_secure_password
  OPENCHAMBER_TUNNEL_MODE: quick # quick | managed-remote | managed-local
  OPENCHAMBER_TUNNEL_PROVIDER: cloudflare

For managed-remote mode, also set:

environment:
  OPENCHAMBER_TUNNEL_MODE: managed-remote
  OPENCHAMBER_TUNNEL_HOSTNAME: app.example.com
  OPENCHAMBER_TUNNEL_TOKEN: <token>

For managed-local mode, you can set:

environment:
  OPENCHAMBER_TUNNEL_MODE: managed-local
  OPENCHAMBER_TUNNEL_CONFIG: /home/openchamber/.cloudflared/config.yml

Managed-local path note: OPENCHAMBER_TUNNEL_CONFIG must use a container path under /home/openchamber/.... If the config file references credentials-file, ensure that JSON path is also mounted and reachable inside the container.

Data directory: mount data/ for persistent storage. Ensure permissions:

mkdir -p data/openchamber data/opencode/share data/opencode/config data/ssh
chown -R 1000:1000 data/
Background & daemon mode
openchamber             # Runs in background by default
openchamber stop        # Stop background server
systemd service (VPN / LAN access)

Use --foreground to keep the CLI process alive so systemd (or any other process manager) can track and restart it. Combine with OPENCODE_HOST to connect to an OpenCode instance running as a separate service.

~/.config/systemd/user/opencode.service

[Unit]
Description=OpenCode Server

[Service]
Type=simple
ExecStart=opencode serve --port 4095
Environment="PATH=/home/linuxbrew/.linuxbrew/bin:/home/linuxbrew/.linuxbrew/sbin:/home/YOU/.local/bin:/home/YOU/.npm-global/bin:/usr/local/bin:/usr/bin:/bin"
Environment=SSH_AUTH_SOCK=%t/ssh-agent.socket
Restart=on-failure
RestartSec=5

[Install]
WantedBy=default.target

Why set PATH and SSH_AUTH_SOCK? systemd user services start with a minimal environment — no shell profile is sourced. Without an explicit PATH, OpenCode won't find tools installed via Homebrew, npm, or ~/.local/bin. Without SSH_AUTH_SOCK, git operations over SSH (push, pull, clone) will fail. %t expands to $XDG_RUNTIME_DIR (e.g. /run/user/1000), where most SSH agents write their socket.

--host 0.0.0.0 is required to listen on all interfaces (the default is 127.0.0.1). Use --host <ip> or OPENCHAMBER_HOST=<ip> to bind to a specific interface instead.
