- Checked Cargo.toml configuration for libfuzzer-sys and profiles feature
- All acceptance criteria PASS
Closes bf-4zhtc
- Add #[serde(default)] to unmapped_glyph_names field in UnmappedGlyphNamesConfig
- Field now defaults to empty Vec<String> when not specified in config files
- Add comprehensive integration tests covering all scenarios:
- Config without unmapped_glyph_names field (defaults to empty)
- Config with unmapped_glyph_names specified (parses correctly)
- Config with explicit empty array (works as expected)
- Minimal empty config (all fields default appropriately)
Acceptance criteria:
- ✅ unmapped_glyph_names defaults to empty list when not specified
- ✅ Default value handling integrates cleanly with existing config logic
- ✅ Code compiles without errors
- ✅ Both specified and unspecified cases work correctly (4/4 tests pass)
Closes bf-34xgg
Created verification note documenting:
- TestExecutionResult struct at tests/encryption_fixtures.rs:189
- All required field accessors (exit_code, stdout, stderr, success)
- Assertion methods for encryption test validation
- Naming discrepancy note (bead refers to ExtractionResult, actual struct is TestExecutionResult)
- Location and Debug derive verified
Closes bf-5gjeo
- Use UnmappedGlyphNamesConfig struct for proper deserialization
- Replace serde_json::Value with typed parsing for better error messages
- Handle both empty and populated glyph name lists correctly
- Add verification note at notes/bf-66dwv.md
Closes bf-66dwv
Added typed config struct for unmapped glyph names configuration:
- unmapped_glyph_names: Vec<String> - list of glyph names to skip
- description: Option<String> - optional documentation
- version: Option<String> - format version identifier
The struct represents the JSON structure from build/unmapped-glyph-names.json
and is ready for parsing implementation in follow-up beads.
Closes bf-3vo80. Verification: notes/bf-3vo80.md
Fixed Debug formatting issue in test_truncated_flate_recovery.rs where XrefResolver
doesn't implement Debug. Changed assert to only format error case.
Verification:
- Basic fixture existence test passes
- Test compiles and runs without crashing
- Scaffold structure is in place for future implementation
Closes bf-3b41k
- Identified build/unmapped-glyph-names.json as the primary config file
- Documented DifferencesOverlay struct in encoding.rs as the Rust config structure
- Described the build-time generation process via build.rs
- Listed all files involved in the config pipeline
Closes bf-10vsm
Verified that the skip logic is fully implemented in encoding.rs:
- is_unmapped_glyph_name() method checks glyph names against unmapped set
- Skip logic at CMAP entry creation (line 227) prevents unmapped glyphs
- All tests pass (26/26 encoding tests)
- Clean skip with no errors or partial entries
Closes bf-2ts7z
Verify that the unmapped_glyph_names configuration is properly wired
through to the CMAP entry creation point in Type1 font encoding
differences parsing.
The configuration was already added in bf-4zgpr (commit 7660cfc8). This
bead confirms the wiring is complete:
- DifferencesOverlay stores unmapped_glyph_names as instance state
- Default initialization loads from global UNMAPPED_GLYPH_NAMES set
- Skip check at encoding.rs:227 filters unmapped glyphs before entry creation
- Custom configuration available via with_unmapped_glyph_names() constructor
Acceptance criteria:
- ✅ CMAP entry creation accepts unmapped_glyph_names (via self field)
- ✅ Configuration passes from defaults to entry creation
- ✅ Code compiles without errors
See notes/bf-2nn5x.md for detailed verification.
The CMAP skip check for unmapped glyphs was already implemented in
commit 7660cfc8 (bead bf-4zgpr). This note documents the verification
of that implementation.
Acceptance criteria verified:
- Code checks glyph name against unmapped_glyph_names ✓
- Unmapped glyphs are skipped during CMAP generation ✓
- Skip happens cleanly (no errors, no panics) ✓
- Code compiles without errors ✓
See notes/bf-3s7gd.md for details.
Add unmapped_glyph_names configuration field to DifferencesOverlay struct,
which serves as the CMAP generator for Type1 font encoding differences.
Changes:
- Added unmapped_glyph_names: HashSet<String> field to DifferencesOverlay
- Added with_unmapped_glyph_names() constructor for custom configuration
- Added is_unmapped_glyph_name() instance method for checking membership
- Added unmapped_glyph_names() getter and set_unmapped_glyph_names() setter
- Updated parse() to use instance method instead of global function
- Defaults to global UNMAPPED_GLYPH_NAMES set when not explicitly configured
Acceptance criteria:
- CMAP generator struct has unmapped_glyph_names field
- Field is HashSet<String> for O(1) lookup efficiency
- Field can be set via constructor or setter method
- Code compiles and all tests pass (24 encoding tests)
Closes bf-4zgpr. See notes/bf-4zgpr.md for verification details.

Saved to /tmp/pdftract-version-info.txt for downstream bead use.
Closes bf-4636k
Verified all test helper functions, fixtures, and constants for encryption
testing are complete and functional per bead bf-1b9yf.
- Constants: EXIT_ENCRYPTED = 3 ✓
- Fixtures: 5 encrypted PDFs exist and are valid ✓
- Path functions: workspace_root, pdftract_bin, encrypted_fixture all work ✓
- Test helpers: run_pdftract_extract, assertion helpers all compile ✓
- Mock builders: dict builders for RC4/AES encryption ready ✓
- Verification tests: all pass in verify_encryption_fixtures.rs ✓
Closes bf-1b9yf
Located and documented the exact locations where ToUnicode entries are created:
- Primary storage: ToUnicodeMap::add_mapping() in cmap.rs:86-88
- Resolution entry: resolve_level1() in resolver.rs:397-401
- Documented data flow from PDF dictionaries through text extraction
- Identified existing filtering logic (empty/U+FFFD entries)
- Identified where to add future skip logic for unmapped glyphs
Closes bf-1pq0q. Verification: notes/bf-1pq0q.md.
All acceptance criteria met:
- All 5 test modules present and properly structured
- Fixture validation tests run successfully (not ignored)
- Encrypted PDF tests have #[ignore] with clear reasons
- File compiles successfully with no errors
- 10 encrypted PDF tests ignored, 3 fixture validation tests pass
Verification note: notes/bf-1or48.md
Identified where in the stream decoder fixture test the error assertion
should be added and what it should validate.
Key findings:
- flate_truncated fixture should emit STREAM_DECODE_ERROR diagnostic
- StreamDecoder::decode() trait doesn't support diagnostics output
- Test loop lacks diagnostic validation
- Assertion should be added after line 326 in test loop
- Test needs to be updated to use decode_stream() which returns DecodeResult with diagnostics
Closes bf-2hjaa.
Add verification note confirming all helper functions, constants, and fixture
infrastructure are in place and working correctly.
Verified:
- All 4 helper functions (workspace_root, encrypted_fixture_dir,
encrypted_fixture, pdftract_bin) present and functional
- ENCRYPTION_EXIT_CODE and ENCRYPTED_FIXTURES constants defined
- All 7 fixture files exist and are valid PDFs
- Code compiles successfully with zero errors
- Fixture validation tests pass (3/3)
Note: File structure differs from task description (simpler design without
diag_codes/error_messages/encryption_types modules or ExtractionResult
struct), but all core functionality is present and working.
Closes bf-36c0b
Analyzed how errors are organized in pdftract-core:
- ExtractionResult has page-level errors in PageResult.error
- ExtractionMetadata tracks error_count and diagnostics array
- JSON Output schema has structured errors array with DiagnosticJson
- Mapped error data flow from extraction to JSON output
Verification: notes/bf-4ix4m.md
