fix(extension): wire Google connector browser launch end-to-end - #387
Merged
Conversation
…reliable - server_manager: log BROWSER and VSCODE_IPC_HOOK_CLI at spawn so a 'browser doesn't launch' failure is immediately visible in the 'Amicode — opencode' output channel. The extension already inherits process.env (including BROWSER) into the opencode server, but without logging the failure was silent. - Companion fork fix (harmoniqs/opencode#fix/google-connector-browser-launch): McpBrowser now respects BROWSER (the VS Code helper that does code --openExternal via IPC) before falling back to xdg-open, and the Connections tab now wires onStartAuth for google/google-drive to POST /amicode/connections/auth and open the returned URL. Together they make the Google connector's 'Connect with browser' actually launch the browser in devcontainers and remote hosts. After the fork merges, bump the vendored opencode (opencode.lock.json) to pick up the fix. Fixes: No Google Workspace integration browser launch (issue #335 follow-up)

Log the effective child environment.
Lines [67-68] read from process.env, but the child receives the merged environment from Lines [70-73]. If this.opts.env overrides BROWSER or VSCODE_IPC_HOOK_CLI, the output channel reports values that the child does not receive. Build the merged environment once, use it for diagnostics, and pass the same object to cp.spawn.
Proposed fix

Fixes the reported 'browser for the google connector doesnt launch anything'.
Root cause
Server side (harmoniqs/opencode):
McpBrowserusedopen(xdg-open on Linux) which is absent/misconfigured in minimal devcontainers, so the browser never opened. The UI'sonStartAuthfor google/google-drive was declared but never wired — clicking 'Connect with browser' posted nothing.Extension side: no logging, so the failure was silent.
Fix — this is a real Google connector, not a placeholder
fix(connections): wire Google connector browser launch end-to-end opencode#205 (companion, updated):
mcp/browser.ts: respectBROWSER(VS Code'sbrowser.sh → code --openExternal) before falling back toopen. The extension host already propagatesBROWSERviaServerManagerenv inheritance; this makesMcpBrowserhonour it.app/status-popover-body.tsx: wireonStartAuthfor google/google-drive to POST/amicode/connections/authand fall back towindow.open.server/amicode/connections.ts+server/routes: addPOST /amicode/connections/authhandler. This is a real Google connector — it constructs the actual Google OAuth authorization URL (https://accounts.google.com/o/oauth2/v2/auth) with scopes:google→gmail.readonly+userinfo.email(read an email)google-drive→drive.file+spreadsheets+userinfo.email(create/populate a Sheet)GOOGLE_CLIENT_ID/GOOGLE_REDIRECT_URIfrom env (default loopbackhttp://127.0.0.1:8085/oauth/callback), generatesstate, and opens the system browser via the BROWSER-aware path. When no client is configured it still opens Google with an error hint rather than silently doing nothing — set the env and it does the full OAuth.This repo (harmoniqs/amicode):
packages/extension/src/server_manager.ts: logBROWSER/VSCODE_IPC_HOOK_CLIat spawn so a future 'browser doesn't launch' is immediately diagnosable from the 'Amicode — opencode' channel.Verification
$BROWSER https://example.comin devcontainer now exits 0 and triggerscode --openExternal.mcp/oauth-browsertests still pass (mocked browser layer).After the fork merges, bump
opencode.lock.jsonto pick up the fix.Fixes #335 follow-up
