Cacheout v2.1.2

Menubar icon hotfix

v2.1.1 correctly bundled menubar icon resources into the .app, but the source PNGs in Sources/Cacheout/Resources/ were a faint single-line "C" outline that rendered effectively invisible at 18×18 in template mode. The actual master artwork had been dropped from the repo at some point.

Fixed

• Restored Resources/menubar-icon-master.PNG (the 2048×2048 master) and regenerated all four bundled variants — MenuBarIcon.png, MenuBarIcon@2x.png, MenuBarIconTemplate.png, MenuBarIconTemplate@2x.png — at the correct 18×18 / 36×36 sizes from the master. The Cacheout "C" now actually appears in the menubar.

Everything else from v2.1.0 + v2.1.1 (Sparkle auto-update bundling, helper daemon, security/perf/UX fixes) is unchanged.

Cacheout v2.1.1

Hotfix for v2.1.0

v2.1.0 shipped with two regressions: the menubar icon resources and the CacheoutHelper privileged daemon were silently dropped from the .app bundle. v2.1.1 restores both.

Fixed

• Menubar icon now displays again. Bundle.main.image(forResource: "MenuBarIconTemplate") couldn't find the PNG resources because scripts/bundle.sh was only copying Cacheout.icns. Now copies all four icon variants (regular + @2x, template + non-template) into Contents/Resources/.
• CacheoutHelper daemon is now bundled at Contents/Library/LaunchDaemons/. The SMAppService.daemon(plistName:) registration relies on the binary + plist being inside the app bundle. Without them, the onboarding install-helper flow and --daemon autopilot silently broke. The helper is now signed before the outer app so codesign --verify --deep --strict passes.

Everything else in v2.1.0 (Sparkle auto-update bundling, HTTPS webhook enforcement, process pipe + PID-lock-fd-leak fixes, dictionary/scanner perf work, dynamic button labels + tooltips, empty states, accessibility) is unchanged.

Cacheout v2.1.0

⚠️ Known issue — please install v2.1.1 instead

v2.1.0 is missing the custom menubar icon resources and the CacheoutHelper daemon binary from the .app bundle (a scripts/bundle.sh regression). The menubar item can appear blank, and the install-helper onboarding flow / --daemon autopilot silently break. Both issues are fixed in v2.1.1 ↘

What's new in v2.1.0

🚀 Auto-updates land

Sparkle.framework is now bundled inside Cacheout.app/Contents/Frameworks/ with the correct @executable_path/../Frameworks rpath, signed inner→outer with hardened runtime. Starting from this build, future releases will be installable via in-app auto-update instead of manual reinstall.

🎨 UX polish (Palette)

• Dynamic Scanning… / Cleaning… labels on the Scan/Clean buttons with .help() tooltips explaining disabled states
• .help() tooltips on per-process ellipsis menus
• Visual empty state for the node_modules section (centered icon + callout)
• Accessibility labels on icon-only controls so VoiceOver stops reading "Button"
• Empty state for the Processes view

🛡️ Security & reliability (Sentinel)

• HTTPS-only webhooks — AutopilotConfigValidator and WebhookConfig.parse both reject http://
• PID lock fd no longer leaks to children — open(2) now uses O_CLOEXEC and withUnsafeFileSystemRepresentation
• Process pipe deadlock fix — CacheoutViewModel.runCleanCommand (docker prune path) reads stdout before waitUntilExit()
• Defense-in-depth pipe-deadlock guards across other process execution paths
• Command injection vulnerabilities closed in runCleanCommand and CacheCategory.toolExists
• Docker pruning now resolves via /usr/bin/env docker so Apple Silicon /opt/homebrew/bin users actually run it

⚡ Performance (Bolt)

• JetsamHWM priority map built with reduce(into:) — no COW thrash
• ProcessMemoryScanner uses a sliding-window TaskGroup
• Scanner TaskGroups marked nonisolated so subtasks parallelize off the actor executor
• Shared ByteCountFormatter/ISO8601DateFormatter instances + .lazy.filter.reduce
• Batched @Published array mutations — one SwiftUI re-render per scan instead of N
• CacheScanner enumerator prefetches .isRegularFileKey
• NodeModulesScanner is truly concurrent with reduced syscalls
• Blocking I/O offloaded via Task.detached so async @MainActor methods no longer stall the UI

🐛 Bug fixes

• Process names no longer display as "unknown" in the main process list
• Guard against empty arguments in runCleanCommand
