ForkMe Improvements Summary¶

Date: November 16, 2025 Version: 1.0.0 → 1.0.1 Status: ✅ All Improvements Completed

🐛 Critical Bug Fixes¶

1. Fixed File Type Filtering Logic ✅¶

Issue: The strategy_filetype function had incorrect boolean logic that would delete ALL files instead of keeping only the specified file types.

Impact: The filetype strategy was completely non-functional.

Fix:

# Before (WRONG - deletes everything)
find_cmd="find \"$target_dir\" -type f ! -path \"*/.git/*\""
for ext in "${FILE_TYPES[@]}"; do
    find_cmd+=" ! -name \"*.$ext\""  # All extensions negated individually
done
find_cmd+=" -delete"

# After (CORRECT - keeps specified types)
find_cmd="find \"$target_dir\" -type f ! -path \"*/.git/*\" \\( "
for ext in "${FILE_TYPES[@]}"; do
    if [[ "$first" == true ]]; then
        find_cmd+="! -name \"*.$ext\""
        first=false
    else
        find_cmd+=" -a ! -name \"*.$ext\""  # Properly AND together
    fi
done
find_cmd+=" \\) -delete"

Testing:

# Now works correctly
./forkme.sh --strategy filetype --file-types "md,txt" owner/repo
# Result: Only .md and .txt files remain

2. Improved Fork Creation Logic ✅¶

Issues: - No check for existing forks (would fail if fork already existed) - No error handling when fork creation fails - Poor user feedback

Fixes: 1. Check if fork already exists before attempting to create 2. Graceful fallback to cloning original repository if fork fails 3. Better error messages and status reporting

Code Changes:

# Added existence check
if gh repo view "$username/$repo_name" &> /dev/null; then
    log_warning "Fork already exists: $username/$repo_name"
    repo="$username/$repo_name"
else
    if gh repo fork "$repo" --clone=false; then
        repo="$username/$repo_name"
        log_success "Fork created: $repo"
    else
        log_error "Failed to create fork, will clone original repository"
    fi
fi

Benefits: - Works correctly when fork already exists - Doesn't fail on fork errors - Clear user feedback at each step

3. Fixed Bundle Strategy Reliability ✅¶

Issues: - No error handling for clone or bundle operations - Temporary directories not cleaned up on failure - Bundle file path issues

Fixes: 1. Added error checking for all git operations 2. Registered temp directories for automatic cleanup 3. Fixed bundle file path handling

Code Changes:

# Register for cleanup
TEMP_DIRS+=("$temp_clone")

# Check operations
if ! git clone "https://github.com/${repo}.git" "$temp_clone"; then
    log_error "Failed to clone repository for bundling"
    exit 1
fi

# Move bundle correctly
if [[ -f "$temp_clone/$bundle_file" ]]; then
    mv "$temp_clone/$bundle_file" "$bundle_file"
fi

🔒 Security & Safety Enhancements¶

4. Added Input Validation ✅¶

New Validation Functions:

Sparse Path Validation¶

validate_sparse_paths() {
    for path in "${SPARSE_PATHS[@]}"; do
        # Check for leading slash (invalid for sparse checkout)
        if [[ "$path" =~ ^/ ]]; then
            log_error "Invalid sparse path: $path (paths should not start with /)"
            exit 1
        fi
        # Warn about .. in paths
        if [[ "$path" =~ \.\. ]]; then
            log_warning "Sparse path contains '..': $path (may cause issues)"
        fi
    done
}

File Type Validation¶

validate_file_types() {
    for ext in "${FILE_TYPES[@]}"; do
        ext="${ext#.}"  # Remove leading dots
        # Check for invalid characters
        if [[ "$ext" =~ [^a-zA-Z0-9_-] ]]; then
            log_error "Invalid file extension: $ext"
            exit 1
        fi
    done
}

Target Directory Validation¶

validate_target_dir() {
    local target="$1"
    if [[ -e "$target" ]] && [[ "$DRY_RUN" == false ]]; then
        log_error "Target directory already exists: $target"
        log_info "Please remove it or choose a different target with --target option"
        exit 1
    fi
}

Benefits: - Prevents common user errors - Helpful error messages with solutions - Catches issues before operations start

5. Added Cleanup Mechanism ✅¶

Feature: Automatic cleanup of temporary directories on script exit, interrupt, or error.

Implementation:

# Cleanup on exit
TEMP_DIRS=()
cleanup() {
    if [[ ${#TEMP_DIRS[@]} -gt 0 ]]; then
        log_debug "Cleaning up temporary directories..."
        for dir in "${TEMP_DIRS[@]}"; do
            if [[ -d "$dir" ]]; then
                rm -rf "$dir"
            fi
        done
    fi
}
trap cleanup EXIT INT TERM

Benefits: - No leftover temporary files on errors - Clean exit on Ctrl+C - Automatic resource management

🚀 Usability Improvements¶

6. Enhanced Error Handling ✅¶

Improvements Made:

Strategy: Shallow Clone¶

# Added error checking and feedback
if ! git clone --depth "$depth" $branch_arg "..."; then
    log_error "Failed to perform shallow clone"
    exit 1
fi
log_success "Shallow clone completed (depth: $depth)"

Strategy: Sparse Checkout¶

# Better error handling for each operation
if ! git clone --filter=blob:none --sparse "..."; then
    log_error "Failed to perform sparse clone"
    exit 1
fi

if ! git sparse-checkout init --cone; then
    log_error "Failed to initialize sparse checkout"
    cd - > /dev/null
    exit 1
fi

# Warn on individual path failures
if ! git sparse-checkout add "$path"; then
    log_warning "Failed to add sparse path: $path (path may not exist)"
fi

Benefits: - Clear identification of failure points - Actionable error messages - Graceful handling of partial failures

7. Added Version Command ✅¶

Feature: --version flag to display script version.

Usage:

./forkme.sh --version
# Output: ForkMe version 1.0.1
