From 58fe00057cc890893d866b9d3ad0b68f66a43df1 Mon Sep 17 00:00:00 2001 From: Steve Yegge Date: Fri, 21 Nov 2025 19:32:45 -0500 Subject: [PATCH] feat: Complete GH #353 follow-up phases (bd-9nw, bd-u3t, bd-e0o) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Implements all three follow-up phases for sandbox environment support: **Phase 1 (bd-9nw): Documentation** ✅ - Comprehensive sandbox troubleshooting section in TROUBLESHOOTING.md - Detailed symptoms, root causes, and escape hatches - Step-by-step troubleshooting workflow - Comparison table for --sandbox, --force, and --allow-stale flags - Global flags section added to CLI_REFERENCE.md - Documents --sandbox, --allow-stale, and --force flags - Usage examples and when to use each flag - GitHub issue #353 comment with immediate workarounds **Phase 2 (bd-u3t): Sandbox Auto-Detection** ✅ - Automatic sandbox detection using syscall.Kill permission checks - cmd/bd/sandbox_unix.go: Unix/Linux/macOS implementation - cmd/bd/sandbox_windows.go: Windows stub (conservative approach) - cmd/bd/sandbox_test.go: Comprehensive test coverage - Auto-enables sandbox mode when detected - Shows: "ℹ️ Sandbox detected, using direct mode" - Respects explicit --sandbox or --no-daemon flags - Updated documentation to reflect auto-detection (v0.21.1+) **Phase 3 (bd-e0o): Enhanced Daemon Robustness** ✅ - Permission-aware process checks in cmd/bd/daemon_unix.go - Correctly handles EPERM (operation not permitted) from syscall.Kill - Treats EPERM as "process exists but not signable" = running - Prevents false negatives in sandboxed environments - Metadata health check in cmd/bd/daemon_event_loop.go - Periodic verification that metadata is accessible - Helps detect external import operations (bd import --force) - Non-fatal logging for diagnostics - Comprehensive test suite in cmd/bd/daemon_unix_test.go - Self-check, init process, nonexistent process, parent process tests **Impact:** - Codex users: No manual intervention needed, auto-detected - Stuck states: Three escape hatches (--sandbox, --force, --allow-stale) - Daemon robustness: Handles permission-restricted environments gracefully - All three follow-up issues (bd-9nw, bd-u3t, bd-e0o) closed **Files changed:** - cmd/bd/main.go: Auto-detection logic in PersistentPreRun - cmd/bd/sandbox_unix.go: Unix sandbox detection (new) - cmd/bd/sandbox_windows.go: Windows sandbox detection stub (new) - cmd/bd/sandbox_test.go: Sandbox detection tests (new) - cmd/bd/daemon_unix.go: Permission-aware isProcessRunning() - cmd/bd/daemon_unix_test.go: Process check tests (new) - cmd/bd/daemon_event_loop.go: Metadata health check - docs/TROUBLESHOOTING.md: Comprehensive sandbox section - docs/CLI_REFERENCE.md: Global flags documentation Closes bd-9nw, bd-u3t, bd-e0o Related: GH #353 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- cmd/bd/daemon_event_loop.go | 14 ++++- cmd/bd/daemon_unix.go | 24 ++++++++- cmd/bd/daemon_unix_test.go | 50 +++++++++++++++++ cmd/bd/main.go | 9 ++++ cmd/bd/sandbox_test.go | 30 +++++++++++ cmd/bd/sandbox_unix.go | 40 ++++++++++++++ cmd/bd/sandbox_windows.go | 20 +++++++ docs/CLI_REFERENCE.md | 77 ++++++++++++++++++++++++++ docs/TROUBLESHOOTING.md | 105 +++++++++++++++++++++++++++++++++--- 9 files changed, 360 insertions(+), 9 deletions(-) create mode 100644 cmd/bd/daemon_unix_test.go create mode 100644 cmd/bd/sandbox_test.go create mode 100644 cmd/bd/sandbox_unix.go create mode 100644 cmd/bd/sandbox_windows.go diff --git a/cmd/bd/daemon_event_loop.go b/cmd/bd/daemon_event_loop.go index 7db5cab1..6e019225 100644 --- a/cmd/bd/daemon_event_loop.go +++ b/cmd/bd/daemon_event_loop.go @@ -166,10 +166,20 @@ func runEventDrivenLoop( // checkDaemonHealth performs periodic health validation. // Separate from sync operations - just validates state. +// +// Implements bd-e0o: Phase 3 daemon robustness for GH #353 func checkDaemonHealth(ctx context.Context, store storage.Storage, log daemonLogger) { - // TODO(bd-gqo): Add health checks: + // Health check: Verify metadata is accessible + // This helps detect if external operations (like bd import --force) have modified metadata + // Without this, daemon may continue operating with stale metadata cache + if _, err := store.GetMetadata(ctx, "last_import_hash");
