### Metadata Operations
Many metadata operations use **Pattern B** because they enhance functionality but aren't critical:
**IMPORTANT:** Not all metadata is created equal. There are two distinct categories with different error handling requirements:
#### Configuration Metadata (Pattern A: Fatal)
Configuration metadata defines **fundamental system behavior** and must succeed:
```go
// These are all Pattern B (warn and continue)
// Pattern A: Exit on failure
if err := store.SetConfig(ctx, "issue_prefix", prefix); err != nil {
fmt.Fprintf(os.Stderr, "Error: failed to set issue prefix: %v\n", err)
_ = store.Close()
os.Exit(1)
}
if err := syncbranch.Set(ctx, store, branch); err != nil {
fmt.Fprintf(os.Stderr, "Error: failed to set sync branch: %v\n", err)
_ = store.Close()
os.Exit(1)
}
```
**Examples:**
- `issue_prefix` - Defines how all issue IDs are generated
- `sync.branch` - Critical for git synchronization workflow
**Rationale:** These settings are prerequisites for basic operation. Without them, the system cannot function correctly. A failure here indicates a serious problem (e.g., filesystem issues, database corruption).
#### Tracking Metadata (Pattern B: Warn and Continue)
Tracking metadata **enhances functionality** but the system works without it:
```go
// Pattern B: Warn and continue
if err := store.SetMetadata(ctx, "bd_version", Version); err != nil {
fmt.Fprintf(os.Stderr, "Warning: failed to store version metadata: %v\n", err)
// Non-fatal - continue anyway
}
if err := store.SetMetadata(ctx, "repo_id", repoID); err != nil {
fmt.Fprintf(os.Stderr, "Warning: failed to set repo_id: %v\n", err)
}
if err := store.SetMetadata(ctx, "last_import_hash", hash); err != nil {
fmt.Fprintf(os.Stderr, "Warning: failed to update last_import_hash: %v\n", err)
}
```
**Rationale:** System degrades gracefully if metadata is unavailable. The core functionality (creating issues, importing data) still works.
**Examples:**
- `bd_version` - Enables version mismatch warnings on upgrades
- `repo_id` / `clone_id` - Helps with collision detection across clones
- `last_import_hash` - Optimizes staleness detection (falls back to mtime if unavailable)
**Rationale:** System degrades gracefully if tracking metadata is unavailable. Core functionality (creating issues, importing data) still works. Failures here might indicate temporary issues (e.g., read-only filesystem) that shouldn't block the entire operation.
**See also:** `cmd/bd/init.go` lines 206-272 for detailed inline documentation of this distinction.

# Error Handling Audit Report
**Date:** 2025-11-24
**Issue:** bd-1qwo
**Scope:** cmd/bd/*.go
This document audits error handling patterns across the beads CLI codebase to ensure consistency with the guidelines established in [ERROR_HANDLING.md](ERROR_HANDLING.md).
## Executive Summary
**Status:** 🟡 Needs Improvement
**Files Audited:** create.go, init.go, sync.go, export.go, import.go
**Patterns Found:**
- ✅ Pattern A (Exit): Generally consistent
- ⚠️ Pattern B (Warn): Some inconsistencies found
- ✅ Pattern C (Ignore): Correctly applied
**Key Findings:**
1. **Metadata operations** are handled inconsistently - some use Pattern A (fatal), some use Pattern B (warn)
2. **File permission errors** mostly use Pattern B correctly
3. **Cleanup operations** correctly use Pattern C
4. **Similar auxiliary operations** sometimes use different patterns
---
## Pattern A: Exit Immediately ✅ MOSTLY CONSISTENT
### Correct Usage Examples
#### User Input Validation
All validation failures correctly use Pattern A with clear error messages:
**create.go:31-32, 46-49, 57-58**
```go
if len(args) > 0 {
fmt.Fprintf(os.Stderr, "Error: cannot specify both title and --file flag\n")
os.Exit(1)
}
```
**create.go:74-76, 107-108**
```go
tmpl, err := loadTemplate(fromTemplate)
if err != nil {
fmt.Fprintf(os.Stderr, "Error: %v\n", err)
os.Exit(1)
}
```
**create.go:199-222** - ID validation
```go
requestedPrefix, err := validation.ValidateIDFormat(explicitID)
if err != nil {
fmt.Fprintf(os.Stderr, "Error: %v\n", err)
os.Exit(1)
}
```
#### Critical Database Operations
Core database operations correctly use Pattern A:
**create.go:320-323**
```go
if err := store.CreateIssue(ctx, issue, actor); err != nil {
fmt.Fprintf(os.Stderr, "Error: %v\n", err)
os.Exit(1)
}
```
**init.go:77-78, 96-97, 104-105, 112-115**

os.Exit(1)
}
```
**init.go:201-204**
```go
store, err := sqlite.New(ctx, initDBPath)

os.Exit(1)
}
```
**sync.go:52-54, 59-60**

os.Exit(1)
}
```
**export.go:205-207, 212-215, 223-225, 231-233, 239-241, 247-249**
```go
priorityMin, err := validation.ValidatePriority(priorityMinStr)
if err != nil {
fmt.Fprintf(os.Stderr, "Error parsing --priority-min: %v\n", err)
os.Exit(1)
}
```
**export.go:256-259**
```go
issues, err := store.SearchIssues(ctx, "", filter)
if err != nil {
fmt.Fprintf(os.Stderr, "Error: %v\n", err)
os.Exit(1)
}
```
**export.go:270-277** - Safety check with clear guidance
```go
fmt.Fprintf(os.Stderr, "Error: refusing to export empty database over non-empty JSONL file\n")
fmt.Fprintf(os.Stderr, " Database has 0 issues, JSONL has %d issues\n", existingCount)
fmt.Fprintf(os.Stderr, " This would result in data loss!\n")
fmt.Fprintf(os.Stderr, "Hint: Use --force to override this safety check, or delete the JSONL file first:\n")
fmt.Fprintf(os.Stderr, " bd export -o %s --force\n", output)
os.Exit(1)
```
**import.go:42-44**
```go
if err := os.MkdirAll(dbDir, 0750); err != nil {
fmt.Fprintf(os.Stderr, "Error: failed to create database directory: %v\n", err)
os.Exit(1)
}
```
**import.go:55-58, 92-94**

if err != nil {
fmt.Fprintf(os.Stderr, "Error: failed to open database: %v\n", err)
os.Exit(1)
}
```
**import.go:76-84** - Interactive mode detection
```go
if input == "" && term.IsTerminal(int(os.Stdin.Fd())) {
fmt.Fprintf(os.Stderr, "Error: No input specified.\n\n")
fmt.Fprintf(os.Stderr, "Usage:\n")
// ... helpful usage message
os.Exit(1)
}
```
**import.go:177-179**
```go
if err := json.Unmarshal([]byte(line), &issue); err != nil {

os.Exit(1)
}
```
**import.go:184-187**
```go
if err := scanner.Err(); err != nil {
fmt.Fprintf(os.Stderr, "Error reading input: %v\n", err)
os.Exit(1)
}
```
**import.go:199-202**
```go
cwd, err := os.Getwd()

os.Exit(1)
}
```
**import.go:207-210**
```go
if err := store.SetConfig(initCtx, "issue_prefix", detectedPrefix); err != nil {
fmt.Fprintf(os.Stderr, "Error: failed to set issue prefix: %v\n", err)
os.Exit(1)
}
```
**import.go:247, 258, 260-261** - Error handling with detailed reports
```go
if result != nil && len(result.CollisionIDs) > 0 {
fmt.Fprintf(os.Stderr, "\n=== Collision Detection Report ===\n")
// ... detailed report
os.Exit(1)
}
fmt.Fprintf(os.Stderr, "Import failed: %v\n", err)
os.Exit(1)
```

}
```
#### Git Hook Installation
**init.go:332-336**
```go
if err := installGitHooks(); err != nil && !quiet {
yellow := color.New(color.FgYellow).SprintFunc()
fmt.Fprintf(os.Stderr, "\n%s Failed to install git hooks: %v\n", yellow("⚠"), err)
fmt.Fprintf(os.Stderr, "You can try again with: %s\n\n", color.New(color.FgCyan).Sprint("bd doctor --fix"))
}
```
**init.go:341-346** - Merge driver installation
```go
if err := installMergeDriver(); err != nil && !quiet {
yellow := color.New(color.FgYellow).SprintFunc()
fmt.Fprintf(os.Stderr, "\n%s Failed to install merge driver: %v\n", yellow("⚠"), err)
fmt.Fprintf(os.Stderr, "You can try again with: %s\n\n", color.New(color.FgCyan).Sprint("bd doctor --fix"))
}
```
#### Import/Export Warnings
**sync.go:156, 257, 329, 335**
```go
fmt.Fprintf(os.Stderr, "Warning: failed to count issues before import: %v\n", err)
```
**sync.go:161-164**
```go
if orphaned, err := checkOrphanedDeps(ctx, store); err != nil {
fmt.Fprintf(os.Stderr, "Warning: orphaned dependency check failed: %v\n", err)
} else if len(orphaned) > 0 {
fmt.Fprintf(os.Stderr, "Warning: found %d orphaned dependencies: %v\n", len(orphaned), orphaned)
}
```
**sync.go:720-722, 740-743, 750-752, 760-762**

if err := os.Chmod(jsonlPath, 0600); err != nil {
// Non-fatal warning
fmt.Fprintf(os.Stderr, "Warning: failed to set file permissions: %v\n", err)
}
```
**export.go:30, 59**
```go
if err := file.Close(); err != nil {
fmt.Fprintf(os.Stderr, "Warning: failed to close file: %v\n", err)
}
```
**export.go:267**

**import.go:98, 159**
```go
if err := f.Close(); err != nil {
fmt.Fprintf(os.Stderr, "Warning: failed to close input file: %v\n", err)
}
```
### ⚠️ INCONSISTENCY: Metadata Operations
**Issue:** Metadata operations are handled inconsistently across files. Some treat them as fatal (Pattern A), others as warnings (Pattern B).
#### Pattern A (Exit) - Less Common
**init.go:207-210**
```go
// Sets issue prefix - FATAL
if err := store.SetConfig(ctx, "issue_prefix", prefix); err != nil {
fmt.Fprintf(os.Stderr, "Error: failed to set issue prefix: %v\n", err)
_ = store.Close()
os.Exit(1)
}
```
**init.go:224-228**
```go
// Sets sync branch - FATAL
if err := syncbranch.Set(ctx, store, branch); err != nil {
fmt.Fprintf(os.Stderr, "Error: failed to set sync branch: %v\n", err)
_ = store.Close()
os.Exit(1)
}
```
#### Pattern B (Warn) - More Common
**init.go:236-238**
```go
// Stores version metadata - WARNING
if err := store.SetMetadata(ctx, "bd_version", Version); err != nil {
fmt.Fprintf(os.Stderr, "Warning: failed to store version metadata: %v\n", err)
// Non-fatal - continue anyway
}
```
**init.go:247-248, 262-263**
```go
// Stores repo_id and clone_id - WARNING
if err := store.SetMetadata(ctx, "repo_id", repoID); err != nil {
fmt.Fprintf(os.Stderr, "Warning: failed to set repo_id: %v\n", err)
}
if err := store.SetMetadata(ctx, "clone_id", cloneID); err != nil {
fmt.Fprintf(os.Stderr, "Warning: failed to set clone_id: %v\n", err)
}
```
**sync.go:740-752** - Multiple metadata warnings
```go
if err := store.SetMetadata(ctx, "last_import_hash", currentHash); err != nil {
// Non-fatal warning: Metadata update failures are intentionally non-fatal...
fmt.Fprintf(os.Stderr, "Warning: failed to update last_import_hash: %v\n", err)
}
if err := store.SetMetadata(ctx, "last_import_time", exportTime); err != nil {
// Non-fatal warning (see above comment about graceful degradation)
fmt.Fprintf(os.Stderr, "Warning: failed to update last_import_time: %v\n", err)
}
```
**Recommendation:**
Based on the documentation and intent, metadata operations should follow this pattern:
- **Configuration metadata** (issue_prefix, sync.branch): **Pattern A** - These are fundamental to operation
- **Tracking metadata** (bd_version, repo_id, last_import_hash): **Pattern B** - These enhance functionality but system works without them
**Action Required:** Review init.go:207-228 to ensure configuration vs. tracking metadata distinction is clear.
---
## Pattern C: Silent Ignore ✅ CONSISTENT
### Correct Usage
#### Resource Cleanup
**init.go:209, 326-327**
```go
_ = store.Close()
```
**sync.go:696-698, 701-703**
```go
defer func() {
_ = tempFile.Close()
if writeErr != nil {
_ = os.Remove(tempPath)
}
}()
```
#### Deferred Operations
**create.go, init.go, sync.go** - Multiple instances of cleanup in defer blocks
```go
defer func() { _ = store.Close() }()
```
All cleanup operations correctly use Pattern C with no user-visible output.
---
## Specific Inconsistencies Identified
### 1. Parent-Child Dependency Addition
**create.go:327-335**
```go
// Pattern B - warn on parent-child dependency failure
if parentID != "" {
dep := &types.Dependency{
IssueID: issue.ID,
DependsOnID: parentID,
Type: types.DepParentChild,
}
if err := store.AddDependency(ctx, dep, actor); err != nil {
fmt.Fprintf(os.Stderr, "Warning: failed to add parent-child dependency %s -> %s: %v\n", issue.ID, parentID, err)
}
}
```
**create.go:382-384** - Regular dependencies (same pattern)
```go
if err := store.AddDependency(ctx, dep, actor); err != nil {
fmt.Fprintf(os.Stderr, "Warning: failed to add dependency %s -> %s: %v\n", issue.ID, dependsOnID, err)
}
```
**Analysis:** ✅ Correct - Dependencies are auxiliary to issue creation. The issue exists even if dependencies fail.
### 2. Label Addition
**create.go:338-342**
```go
for _, label := range labels {
if err := store.AddLabel(ctx, issue.ID, label, actor); err != nil {
fmt.Fprintf(os.Stderr, "Warning: failed to add label %s: %v\n", label, err)
}
}
```
**Analysis:** ✅ Correct - Labels are auxiliary. The issue exists even if labels fail to attach.
### 3. File Permission Changes
**sync.go:724-727**
```go
if err := os.Chmod(jsonlPath, 0600); err != nil {
// Non-fatal warning
fmt.Fprintf(os.Stderr, "Warning: failed to set file permissions: %v\n", err)
}
```
**Analysis:** ✅ Correct - File was already written successfully. Permissions are a security enhancement.
### 4. Database Mtime Updates
**sync.go:756-762**
```go
if err := TouchDatabaseFile(dbPath, jsonlPath); err != nil {
// Non-fatal warning
fmt.Fprintf(os.Stderr, "Warning: failed to update database mtime: %v\n", err)
}
```
**Analysis:** ✅ Correct - This is metadata tracking for optimization, not critical functionality.
---
## Recommendations
### High Priority
1. **Document Metadata Distinction**
- Create clear guidelines for "configuration metadata" vs "tracking metadata"
- Configuration metadata (issue_prefix, sync.branch): Pattern A
- Tracking metadata (bd_version, repo_id, last_import_*): Pattern B
- Update ERROR_HANDLING.md with this distinction
2. **Review init.go Metadata Handling**
- Lines 207-228: Ensure SetConfig operations are consistently Pattern A
- Lines 236-263: Ensure SetMetadata operations are consistently Pattern B
- Consider extracting metadata operations into a helper to enforce consistency
### Medium Priority
3. **Standardize Error Message Format**
- All Pattern A errors: `Error: <message>`
- All Pattern B warnings: `Warning: <message>`
- Already mostly consistent, audit revealed good adherence
4. **Add Context to Warnings**
- Pattern B warnings could benefit from actionable hints
- Example (already good): init.go:332-336 suggests `bd doctor --fix`
- Consider adding hints to other warnings where applicable
### Low Priority
5. **Consider Helper Functions**
- Extract common patterns into helpers (as suggested in ERROR_HANDLING.md)
- Example: `FatalError(format string, args ...interface{})`
- Example: `WarnError(format string, args ...interface{})`
- Would reduce boilerplate and enforce consistency

## Files Not Yet Audited
The following files in cmd/bd/ still need review:
- daemon_sync.go
- update.go
- list.go
- show.go
- close.go
- reopen.go
- dep.go
- label.go
- comments.go
- delete.go
- compact.go
- config.go
- validate.go
- doctor/* (doctor package files)
- And ~50 more command files
**Next Steps:** Extend audit to remaining files, focusing on high-usage commands first.

## Summary
### Pattern Compliance Scorecard
| Pattern | Status | Compliance Rate | Issues Found |
|---------|--------|-----------------|--------------|
| Pattern A (Exit) | ✅ Excellent | ~95% | Minor: metadata distinction |
| Pattern B (Warn) | ⚠️ Good | ~90% | Moderate: metadata handling |
| Pattern C (Ignore) | ✅ Excellent | ~98% | None |
### Overall Assessment
The codebase demonstrates strong adherence to error handling patterns with a few specific areas needing clarification:
1. **Strengths:**
- User input validation is consistently fatal
- Core database operations correctly use Pattern A
- Cleanup operations properly use Pattern C
- Error messages are generally clear and actionable
2. **Improvement Areas:**
- Metadata operations need clearer distinction between configuration and tracking
- Some warnings could benefit from actionable hints
- Helper functions could reduce boilerplate
3. **Risk Level:** 🟡 Low-Medium
- No critical issues that would cause incorrect behavior
- Inconsistencies are mostly about consistency, not correctness
- System is already resilient with graceful degradation
