Что было

На русской Windows без 7-Zip .rar с дистрибутивом платформы объявлялся пустым: info и unpack отвечали nothing_found. Ошибка есть с 2.0.0.

1. Дата. Встроенный tar.exe пишет февр. 18 2025 и на LC_TIME=C не смотрит, а _LISTING_DATE ждал [A-Z][a-z]{2}. Отбрасывались все строки оглавления.
2. Папка. tar.exe пишет extinfo без / на конце. Разбор считал её файлом, и поставка отклонялась с entry_is_also_directory.
3. Пустой ответ вместо отказа. Если не разобрана ни одна строка, list_entries возвращал «архив пуст». Поэтому не пробовалась следующая программа и не появлялся совет поставить 7-Zip.

Что сделано

• Месяц в дате — любое слово, разделители только ASCII. Байт месяца в угаданной кодировке может стать неразрывным пробелом или \x85, поэтому \s и splitlines здесь не годятся.
• Строка с правами на d — папка.
• Вывод с файлами, из которого не разобрано ни строки, теперь значит «программа не справилась». Настоящий пустой архив и архив из одних папок остаются пустыми.
• Тесты на настоящих строках tar.exe, четыре архива добавлены в test_distribution_corpus.py.

Проверено

• pytest с tar.exe из Windows: 942 passed, 69 skipped. ruff без замечаний. Новые тесты и test_listing_is_read_from_a_real_tool[libarchive] без исправления падают.
• Настоящие архивы на русской Windows 11, bsdtar 3.8.9:

Архив	Каталог	Файлов	Время
windows64full_8_3_24_1819.rar	platform/8.3.24.1819/windows-full-x86_64	68	25 с
windows64full_8_3_25_1633.rar	platform/8.3.25.1633/windows-full-x86_64	65	19 с
windows64full_8_3_26_1656.rar	platform/8.3.26.1656/windows-full-x86_64	65	18 с
windows64full_8_5_4_2028.rar	platform/8.5.4.2028/windows-full-x86_64	47	17 с

Все файлы совпали по хешу с прямой распаковкой через tar.exe.

На что смотреть

• Проверена только сборка windows64full, и только через tar.exe. 7-Zip на этой машине нет. Сборки windows64, setuptc и другие не проверялись. Архивов с кириллицей в именах среди проверенных не было.
• Запускался код из исходников, а не собранный EFDUnpacker.exe.
• CI этот случай не воспроизводит: на его машинах, по всей видимости, не русская локаль. Защиту от регрессии дают тесты на зафиксированных строках вывода.

Summary by CodeRabbit

• Bug Fixes
  • Fixed extraction of .rar platform distributions on Russian-language Windows when 7-Zip is unavailable. Archives are now recognized correctly instead of being reported as empty, including archives with directory entries or localized date text. This improves reliability across a broader range of supported platform distributions.

Walkthrough

The RAR listing parser now accepts locale-specific month text and Windows directory listing formats. It distinguishes unparseable listing output from a valid empty archive. Tests add Russian Windows listing cases and four Windows distribution mappings; the changelog records the extraction behavior.

Changes: RAR listing parsing

Layer / File(s)	Summary
Parse locale-specific listings src/efd_unpacker/infrastructure/rar.py, tests/unit/test_rar.py	The parser accepts non-English month text, handles newline and carriage-return separators, and excludes directory entries. Unit tests cover Russian Windows tar listings, altered month text, and directory entries.
Classify listing results src/efd_unpacker/infrastructure/rar.py, tests/unit/test_rar.py, tests/integration/test_distribution_corpus.py, CHANGELOG.md	list_entries returns None when non-directory listing lines cannot be parsed, and an empty tuple for empty or directory-only output. Tests cover both outcomes. The distribution corpus adds four Windows full x86_64 mappings, and the changelog records the Russian Windows behavior.

Merge Risk: Low · previous review 080d7

Some unusual RAR listings can produce incorrect filenames and prevent extraction. The risk is bounded; tighten date matching and add libarchive-only corpus coverage.

Add a libarchive-only corpus variant.

The current corpus test can pass through 7-Zip when libarchive returns no listing. The existing real-tool test does not cover this gap because it uses a generated ZIP. Add a libarchive-only run for these four RAR archives, and skip that variant when libarchive is unavailable.
