Replace the dmc_unrar 1.7.0 backend (third_party/unrar/) with the rarlab
UnRAR 7.20.1 source vendored in third_party/unrar7/ (commit c68c0de),
driven through its C-compatible DLL API.
Why: dmc_unrar only dispatches RAR5 compression version 5
(switch(file->version) case 0x5000). WinRAR 6.x/7.x archives (algorithm
"v6") land on the default branch -> DMC_UNRAR_FILE_UNSUPPORTED_VERSION
-> user-visible "corrupt archive", confirmed on a real v6:8M archive on
2026-09-05. unrar 7.20.1 natively handles v6, multi-volume (.partNN.rar
auto-merge) and encrypted archives.
Engine changes (src/rar_extract.c):
- Facade include swapped to third_party/unrar7/unrar_c_api.h; all calls
now go through RAROpenArchiveEx/RARReadHeaderEx/RARProcessFile/
RARCloseArchive. scan + extract each re-open the archive (the DLL API
is sequential, unlike dmc's index-based access).
- Error translation rewritten for the ERAR_* code set.
- extract no longer builds each staging path by hand (open_parent_dirs/
extract_one removed): unrar writes the whole tree under the staging
root; names were validated during scan.
- Bug fix: normalize_name() cleared the caller-provided *is_dir (it set
*is_dir = 0), turning directory entries into files and tripping the
duplicate detector whenever an explicit directory header followed
files beneath it (real v6 archive had exactly this). RHDF_DIRECTORY
is now honored end to end.
- Encrypted RAR still fails up front (ZIPX_ERR_UNSUPPORTED): unrar can
decrypt, but password plumbing (API/UI) lands in a later commit.
Build:
- Makefile: C++ compiler vars (CXX/HOST_CXX, prospero-clang++ defaults
to -stdlib=libc++), unrar7 RARDLL source set (49 files, mirrors
UnRARDll.vcxproj), .cpp pattern rules, link through the C++ driver.
- tests/run-tests.sh: compiles unrar7 objects with $CXX, links the RAR
test with g++ and -lpowrprof on Windows.
- third_party/unrar/ (dmc_unrar) removed; see git history.
Verified on host (MinGW): full engine run on the user's real v6 archive
(24.9 MB, 170 headers) -> ZIPX_OK, 170/170 entries, 133 files + 37 dirs,
71,514,931 bytes. Host suite: 70 ZIP + 14 RAR checks green.
Frontend password/multi-volume UX and release plumbing (CHANGELOG,
THIRD_PARTY_NOTICES, README, tag) follow in the v1.9 release commit.
