Summary

Adds a Data & Storage section in the General tab of the settings dialog with two path fields:

  • Session database — override path for the opencode session database (OPENCODE_DB)
  • Configuration directory — override path for the opencode config directory (OPENCODE_CONFIG_DIR)

Both fields show resolved XDG defaults as placeholder text, validate on blur (absolute paths required, parent dir must exist for DB, directory must exist for config dir), and trigger a server restart on valid change. Overrides persist across sessions.

Extension-side changes (this PR)

  • chat_bridge.tsdata-storage-query handler (resolves XDG defaults) + data-storage-update handler (validates, writes VS Code settings, restarts server)
  • chat_panel.ts — adds both kinds to Lane 1 (up) and reply kinds to Lane 2 (down)
  • deck/shell.ts — same allowlist additions for the deck surface
  • package.json — adds amicode.sessionDatabase and amicode.configDir configuration properties
  • extension.ts — injects OPENCODE_DB / OPENCODE_CONFIG_DIR into the server spawn env when non-empty

App-side changes (opencode fork)

Branch jj/378-data-storage-settings on harmoniqs/opencode:

  • New: data-storage-controller.ts, data-storage.tsx
  • Modified: general.tsx, context/settings.tsx, i18n/en.ts

Closes #378

@jeonghun-jj-lee, you've reached your PR review limit, so we couldn't start this review.

Next review available in: 5 minutes

Enable usage-based reviews in Billing to review now. Otherwise, wait until the next included review is available.
You're only billed for reviews past your plan's rate limits ($0.25/file).

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Please refer docs for additional details.

📝 Walkthrough

Walkthrough

The extension adds database and configuration-directory settings, resolves storage defaults, validates storage updates, persists valid overrides, restarts the server when appropriate, and injects the overrides into the spawned opencode environment.

Changes

Storage override flow

Layer / File(s) Summary
Storage settings and spawn environment
packages/extension/package.json, packages/extension/src/extension.ts
Adds amicode.sessionDatabase and amicode.configDir settings. spawnEnv reads these settings and maps non-empty values to OPENCODE_DB and OPENCODE_CONFIG_DIR.
Storage query and update handling
packages/extension/src/chat_bridge.ts
Resolves default paths, validates absolute database and configuration paths, persists valid values globally, conditionally restarts the server, and reports status by tab.
Storage message relay
packages/extension/src/chat_panel.ts
Relays storage query and update requests between the iframe and extension host, including defaults and status responses.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Merge Risk: 🟡 Moderate · up to 355f1

Data & Storage updates may appear successful without being saved or applied to the running server, leaving the application on old paths and reporting success even when restart or persistence fails. These bounded correctness issues should be fixed before merging.

Await settings persistence and propagate restart failures.

Make handleAmicodeBridgeMessage asynchronous and update both panel listeners to await it. Await both WorkspaceConfiguration.update calls before amicode.restartServer, and set serverRestarted only after successful completion. Make amicode.restartServer propagate serverManager.start() and fleet-probe failures; it currently catches them and resolves successfully. Post the failure in the status response instead of reporting serverRestarted: true.

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

Refresh storage variables before restarting the existing server.

At Lines 301-305, spawnEnv copies the settings only when a ServerManager is constructed. The amicode.restartServer command stops and starts the existing manager, so a Data & Storage update does not add, replace, or remove OPENCODE_DB and OPENCODE_CONFIG_DIR in its existing environment.

Update currentSpawnEnv after either storage setting changes. Delete both keys before adding the current non-empty overrides. Alternatively, rebuild the ServerManager through spawnEnv during restart.

Proposed direction
+  const applyStorageOverrides = (env: Record<string, string>): void => {
+    delete env.OPENCODE_DB;
+    delete env.OPENCODE_CONFIG_DIR;
+    const cfg = vscode.workspace.getConfiguration("amicode");
+    const sessionDb = cfg.get<string>("sessionDatabase", "").trim();
+    const configDir = cfg.get<string>("configDir", "").trim();
+    if (sessionDb) env.OPENCODE_DB = sessionDb;

Extension-side support for the Data & Storage settings section:

- chat_bridge.ts: add data-storage-query (returns resolved XDG defaults)
  and data-storage-update (validates paths, writes VS Code settings,
  restarts server) handlers
- chat_panel.ts: add both message kinds to Lane 1 (up) and their reply
  kinds (data-storage-defaults, data-storage-status) to Lane 2 (down)
- deck/shell.ts: same allowlist additions for the deck surface
- package.json: add amicode.sessionDatabase and amicode.configDir
  configuration properties
- extension.ts: inject OPENCODE_DB / OPENCODE_CONFIG_DIR into the server
  spawn env when the corresponding VS Code settings are non-empty
…veloper Tools

The placeholder paths now display as ~/... instead of /Users/x/...,
matching the Developer Tools convention. The update handler expands ~
before validating and writing the VS Code setting (same pattern as
dev-tools-rebuild).
