Regression tests for the error handling improvements in fix/flac-error-handling (PR #23). The fix changed decode/encode to return 0 instead of (size_t)-1 on failure, added NULL allocation checks, and fixed a decoder memory leak on init failure. Tests added (flacErrors suite): - decode_garbage_returns_zero: random non-FLAC data - decode_truncated_flac_returns_zero: valid magic, truncated stream - decode_empty_input_returns_zero: NULL source buffer - decode_zero_length_returns_zero: non-NULL but zero-length source - encode_zero_length_no_crash: NULL source, verifies no crash/leak - encode_garbage_roundtrip_fails_cleanly: non-PCM encode + decode - decode_dst_too_small_returns_zero: undersized output buffer All tests are self-contained (no fixture files needed) and pass under AddressSanitizer.
libaaruformat
C implementation of Aaru file format.
The target is to be able to compile it with a normal C (C89 compliant) compiler.
There are no external dependencies.
cmake is not a hard dependency, it's merely for the ease of using IDEs (specifically CLion).
Currently supported features:
- AaruFormat V1 images reading (writing will never be implemented)
- AaruFormat V2 images reading and writing
- LZMA compression
- Claunia Subchannel Transform
- Optical disc tracks
- XML metadata retrieval (writing will never be implemented)
- JSON metadata retrieval and writing
- Hashing while writing (MD5, SHA1, SHA256, SpamSum and BLAKE3)
- Deduplication
- Tape file and partitions
- Dump hardware lists
- Currently on sync (as of October 2025) with Aaru's media type list
- CHS geometry retrieval and setting
- Metadata
- Unit testing
- Automatic generation of API documentation
- It is to all effects feature parity with C#
Things still to be implemented that are already in the C# version:
- Automatic media type generation from C# enumeration
- Nuget package for linking with Aaru
Things to be implemented not in the C# version (maybe):
- Compile for Dreamcast (KallistiOS preferibly)
- Compile for PlayStation Portable
- Compile for Wii
- Compile for Wii U
- Compile for PlayStation 2
- Compile for PlayStation 3
- Snapshots
- Parent images
- Data positioning measurements
Building and Testing
Standard Build
mkdir build
cd build
cmake ..
cmake --build .
Running Tests
cd build
ctest --verbose
Building with Address Sanitizer
For debugging memory issues, you can build with Address Sanitizer enabled:
mkdir build-asan
cd build-asan
cmake -DUSE_ASAN=ON -DCMAKE_BUILD_TYPE=Debug ..
cmake --build .
ctest --verbose
For detailed information on using Address Sanitizer to detect memory issues, see docs/ASAN_USAGE.md.
Other Build Options
-DUSE_SLOG=ON- Enable slog logging for debugging-DUSE_ASAN=ON- Enable Address Sanitizer for memory error detection
