From 4eef3f77a4a8210501a9dfe369ceeac581772939 Mon Sep 17 00:00:00 2001 From: Tam Nhu Tran Date: Wed, 10 Jun 2026 13:25:07 -0400 Subject: [PATCH 1/5] feat(bar): one-flow install with quarantine automation and launch handoff 'ccs bar install' previously ended with two manual steps: clearing the Gatekeeper quarantine by hand and running 'ccs bar' separately. Install now detects an existing installation and says so before reinstalling, clears the quarantine attribute itself via execFile with a graceful fallback to the printed hint when xattr fails, and ends with a TTY-aware 'Launch CCS Bar now?' prompt (default yes) that hands off to the existing launch flow. --launch forces the handoff and --no-launch suppresses it for scripted installs; non-TTY runs skip the prompt and print the manual command instead.

It is a server-side check unrelated to Gatekeeper, and the previous ordering let a failed quarantine clear (always the case where xattr is absent, e.g. Linux CI) skip the handshake entirely. Reinstalls remove the existing bundle before extraction so the post-extraction existence check actually proves the fresh bundle landed; an unremovable bundle aborts install instead of extracting over it. Declining the launch prompt now prints the same run-ccs-bar hint as the non-TTY path instead of ending silently. Install tests inject the newer deps (clearQuarantine, isBarRunning, promptLaunch) everywhere the defaults could touch host binaries, keeping results identical on macOS and Linux runners. --- src/commands/bar/install-subcommand.ts | 74 +++++-- tests/unit/commands/bar-command.test.ts | 283 +++++++++++++++++++++++- 2 files changed, 328 insertions(+), 29 deletions(-) diff --git a/src/commands/bar/install-subcommand.ts b/src/commands/bar/install-subcommand.ts index d5109437..cc3cd068 100644 --- a/src/commands/bar/install-subcommand.ts +++ b/src/commands/bar/install-subcommand.ts @@ -110,6 +110,14 @@ export interface InstallDeps { * Injectable for tests — avoids touching the real process table. */ isBarRunning: () => Promise; + /** + * Remove an existing app bundle before extraction so a malformed archive + * cannot silently leave the old version in place. + * Production: fs.rmSync(appPath, { recursive: true, force: true }). + * Injectable for tests — avoids real filesystem side-effects. + * Throws on failure; caller catches and aborts install. + */ + removeExistingApp: (appPath: string) => void; } // --------------------------------------------------------------------------- @@ -386,6 +394,10 @@ async function defaultClearQuarantine(appPath: string): Promise { } } +function defaultRemoveExistingApp(appPath: string): void { + fs.rmSync(appPath, { recursive: true, force: true }); +} + async function defaultLaunchBar(args: string[]): Promise { const { handleBarLaunch } = await import('./launch-subcommand'); await handleBarLaunch(args); @@ -470,6 +482,7 @@ export async function handleBarInstall( const launchBar = deps.launchBar ?? defaultLaunchBar; const promptLaunch = deps.promptLaunch ?? defaultPromptLaunch; const isBarRunning = deps.isBarRunning ?? defaultIsBarRunning; + const removeExistingApp = deps.removeExistingApp ?? defaultRemoveExistingApp; const ccsDir = (deps.getCcsDir ?? defaultGetCcsDir)(); const appsDir = (deps.getAppsDir ?? defaultGetAppsDir)(); @@ -500,6 +513,21 @@ export async function handleBarInstall( const { downloadUrl } = releaseInfo; console.log(`[i] Installing CCS Bar from ${BAR_RELEASE_TAG}...`); + // 1b.
