Security: remove trojan affected archive in test files
Prepare for v0.11.3 Fix release changelog and tag Signed-off-by: Hiroshi Miura <[email protected]>
Support PPMd; Fix Zstd and Append Mode
Changed
- PPMd: Use stream encoder/decoder instead of buffered one.
- PPMd: Use [email protected] and later.(#268)
Added
- PPMd compression/decompression support.(#255)
- New API to set methods to set header encode mode, encode or encrypted.(#259)
- Support Python 3.9.(#261)
- Support arm64/aarch64 architecture on Linux.(#262)
Fixed
- Append mode cause error when target archive use LZMA2+BCJ.(#266)
- Fix zstandard compression/decompression.(#258)
Deprecated
- Drop support for python 3.5 which become end-of-life in Sept. 2020.
Fix header error when larger archive extraction
Fixed
- Fix exception when reading header which size is larger than buffer size (#252)
A bug affected from v0.10.0a1 to v0.10.0
Support "Append" mode
The version 0.10.0 and its pre-released versions have a critical known bug on header parsing.
You are strongly recommended to use v0.10.1 and later, or v0.9.9.
Changes from v0.9.2
Fixed
- Fix BCJ(x86) filter code with a missing logic which cause extraction error
for certain data. (#249, #250) - Raise PasswordRequired when encrypted header without passing password (#234, #237)
- CLI: don't raise exception when password is wrong or not given.(#229)
- Fix specification typo.
- Catch exception in threading extraction(#218,#219)
Added
- Compatibility test with python-libarchive-c/libarchive for compression(#247)
- Document: express how to handle multi-volume archive (#243)
- SevenZipFile.needs_password() method.(#208, #235)
- CLI: Support append mode command line.(#228)
- Support "APPEND" mode. User can open SevenZipFile() class with mode='a' (#227)
Changed
- Calculate CRC32 of header without re-reading header from disk again.(#245)
- read(), extract(): improve performance when specifying parts of archived file,
by skipping rest of arcvhive when target file has extracted.(#239,#242) - read(), extract(): improve performance when specifying parts of archived file,
by not running threads for unused compression blocks(folders).(#239,#242) - docs: improve API documentation.(#244)
- setup: set minimum required python version as >=3.5
- Compression will be happened when call write() not close() (#222, #226)
- Handle file read/write in SevenZipCompressor/Decompressor class (#213)
Fix BCJ filter failure when certain LZMA+BCJ
Merge pull request #251 from miurahr/backport-lzma-bcj-249 Backport BCJ filter fix
Improve compression mode
- avoid reading header data to calculate crc32 after writing header data, now calculation happened when writing header data.
Support Append mode, needs_password()
Added
- SevenZipFile.needs_password() method.(#208, #235)
- CLI: Support append mode command line.(#228)
- Support "APPEND" mode. User can open SevenZipFile() class with mode='a' (#227)

Fixed
Raise PasswordRequired when encrypted header without password
Fixed
- Raise PasswordRequired when encrypted header and no password given(#238)
Catch LZMAError when wrong password is given
