From 7806937b0a4c6dfa695deada3b99a25fde6a884c Mon Sep 17 00:00:00 2001 From: Steve Yegge Date: Thu, 20 Nov 2025 19:33:12 -0500 Subject: [PATCH] Add bd doctor --fix flag to automatically repair issues (bd-ykd9) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Implements automatic fix capability for bd doctor with user confirmation and security hardening. Features: - Organizes fix implementations under doctor/fix/ directory structure - Shows all fixable issues and prompts for confirmation (Y/n) before applying - Provides clear output about what was fixed and any errors encountered - Re-runs diagnostics after fixes to show updated state - Each fix is idempotent and safe to run multiple times Automatic fixes implemented: - Git hooks (runs bd hooks install) - Daemon health issues (runs bd daemons killall) - DB-JSONL sync problems (runs bd sync --import-only) - File permissions (fixes .beads/ and database permissions) - Database version mismatches (runs bd migrate) - Schema compatibility issues (runs bd migrate) - Gitignore updates (writes canonical template) Security improvements: - Prevents command injection by using os.Executable() instead of PATH lookup - Prevents path traversal attacks with workspace validation - Fixes race conditions by using cmd.Dir instead of os.Chdir() - Corrects file permission logic (proper bit masking) - Validates all operations run in beads workspaces only Files changed: - cmd/bd/doctor.go: Enhanced applyFixes() with confirmation and better UX - cmd/bd/doctor/gitignore.go: Fixed permissions (0600 → 0644) - cmd/bd/doctor/fix/common.go: Security helpers (getBdBinary, validateBeadsWorkspace) - cmd/bd/doctor/fix/hooks.go: Git hooks fix - cmd/bd/doctor/fix/daemon.go: Daemon health fix - cmd/bd/doctor/fix/sync.go: DB-JSONL sync fix - cmd/bd/doctor/fix/permissions.go: File permissions fix - cmd/bd/doctor/fix/migrate.go: Database migration fixes 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- cmd/bd/doctor.go | 87 ++++++++++++++++++++++++++++---- cmd/bd/doctor/fix/common.go | 49 ++++++++++++++++++ cmd/bd/doctor/fix/daemon.go | 48 ++++++++++++++++++ cmd/bd/doctor/fix/hooks.go | 40 +++++++++++++++ cmd/bd/doctor/fix/migrate.go | 38 ++++++++++++++ cmd/bd/doctor/fix/permissions.go | 49 ++++++++++++++++++ cmd/bd/doctor/fix/sync.go | 58 +++++++++++++++++++++ cmd/bd/doctor/gitignore.go | 9 ++-- 8 files changed, 363 insertions(+), 15 deletions(-) create mode 100644 cmd/bd/doctor/fix/common.go create mode 100644 cmd/bd/doctor/fix/daemon.go create mode 100644 cmd/bd/doctor/fix/hooks.go create mode 100644 cmd/bd/doctor/fix/migrate.go create mode 100644 cmd/bd/doctor/fix/permissions.go create mode 100644 cmd/bd/doctor/fix/sync.go diff --git a/cmd/bd/doctor.go b/cmd/bd/doctor.go index a1de3e06..62ddbd95 100644 --- a/cmd/bd/doctor.go +++ b/cmd/bd/doctor.go @@ -17,6 +17,7 @@ import ( _ "github.com/ncruces/go-sqlite3/embed" "github.com/spf13/cobra" "github.com/steveyegge/beads/cmd/bd/doctor" + "github.com/steveyegge/beads/cmd/bd/doctor/fix" "github.com/steveyegge/beads/internal/beads" "github.com/steveyegge/beads/internal/configfile" "github.com/steveyegge/beads/internal/daemon" @@ -133,19 +134,85 @@ func init() { } func applyFixes(result doctorResult) { + // Collect all fixable issues + var fixableIssues []doctorCheck for _, check := range result.Checks { - if check.Status == statusWarning || check.Status == statusError { - switch check.Name { - case "Gitignore": - fmt.Println("Fixing .beads/.gitignore...") - if err := doctor.FixGitignore(); err != nil { - fmt.Fprintf(os.Stderr, " Error: %v\n", err) - } else { - fmt.Println(" ✓ Updated .beads/.gitignore") - } - } + if (check.Status == statusWarning || check.Status == statusError) && check.Fix != "" { + fixableIssues = append(fixableIssues, check) } } + + if len(fixableIssues) == 0 { + fmt.Println("\nNo fixable issues found.") + return + } + + // Show what will be fixed + fmt.Println("\nFixable issues:") + for i, issue := range fixableIssues { + fmt.Printf(" %d. %s: %s\n", i+1, issue.Name, issue.Message) + } + + // Ask for confirmation + fmt.Printf("\nThis will attempt to fix %d issue(s).
