HISTORY of the 7-Zip source code
|
|
--------------------------------
|
|
|
|
16.02 2016-05-21
|
|
-------------------------
|
|
- The BUG in 16.00 - 16.01 was fixed:
|
|
Split Handler (SplitHandler.cpp) returned incorrect
|
|
total size value (kpidSize) for split archives.
|
|
|
|
|
|
16.01 2016-05-19
|
|
-------------------------
|
|
- Some bugs were fixed,
|
|
- Some internal changes to reduce the number of compiler warnings.
|
|
|
|
|
|
16.00 2016-05-10
|
|
-------------------------
|
|
- 7-Zip now can extract multivolume ZIP archives (z01, z02, ... , zip).
|
|
- Some bugs were fixed,
|
|
|
|
|
|
15.12 2015-11-19
|
|
-------------------------
|
|
- The BUG in C version of 7z decoder was fixed:
|
|
7zDec.c : SzDecodeLzma2()
|
|
7z decoder could mistakenly report about decoding error for some 7z archives
|
|
that use LZMA2 compression method.
|
|
The probability to get that mistaken decoding error report was about
|
|
one error per 16384 solid blocks for solid blocks larger than 16 KB (compressed size).
|
|
- The BUG (in 9.26-15.11) in C version of 7z decoder was fixed:
|
|
7zArcIn.c : SzReadHeader2()
|
|
7z decoder worked incorrectly for 7z archives that contain
|
|
empty solid blocks, that can be placed to 7z archive, if some file is
|
|
unavailable for reading during archive creation.
|
|
|
|
|
|
15.09 beta 2015-10-16
|
|
-------------------------
|
|
- The BUG in LZMA / LZMA2 encoding code was fixed.
|
|
The BUG in LzFind.c::MatchFinder_ReadBlock() function.
|
|
If input data size is larger than (4 GiB - dictionary_size),
|
|
the following code worked incorrectly:
|
|
- LZMA : LzmaEnc_MemEncode(), LzmaEncode() : LZMA encoding functions
|
|
for compressing from memory to memory.
|
|
That BUG is not related to LZMA encoder version that works via streams.
|
|
- LZMA2 : multi-threaded version of LZMA2 encoder worked incorrectly, if
|
|
default value of chunk size (CLzma2EncProps::blockSize) is changed
|
|
to value larger than (4 GiB - dictionary_size).
|
|
|
|
|
|
9.38 beta 2015-01-03
|
|
-------------------------
|
|
- The BUG in 9.31-9.37 was fixed:
|
|
IArchiveGetRawProps interface was disabled for 7z archives.
|
|
- The BUG in 9.26-9.36 was fixed:
|
|
Some code in CPP\7zip\Archive\7z\ worked correctly only under Windows.
|
|
|
|
|
|
9.36 beta 2014-12-26
|
|
-------------------------
|
|
- The BUG in command line version was fixed:
|
|
7-Zip created temporary archive in current folder during update archive
|
|
operation, if -w{Path} switch was not specified.
|
|
The fixed 7-Zip creates temporary archive in folder that contains updated archive.
|
|
- The BUG in 9.33-9.35 was fixed:
|
|
7-Zip silently ignored file reading errors during 7z or gz archive creation,
|
|
and the created archive contained only part of file that was read before error.
|
|
The fixed 7-Zip stops archive creation and it reports about error.
|
|
|
|
|
|
9.31 2012-10-31
|
|
-------------------------
|
|
- InBuffer.h : CInBuffer uses ISequentialInStream *_stream; instead of CMyComPtr<ISequentialInStream>
|
|
OutBuffer.h: COutBuffer uses ISequentialOutStream *_stream; instead of CMyComPtr<ISequentialOutStream>
|
|
|
|
|
|
9.26 2011-04-11
|
|
-------------------------
|
|
- The BUG was fixed: multi-threaded ZIP stored file size that was at scan stage,
|
|
So if the file was changed after scan, the Unpack Size field was incorrect
|
|
|
|
|
|
9.21 2011-04-11
|
|
-------------------------
|
|
- New class FString for file names at file systems.
|
|
- Speed optimization in CRC code for big-endian CPUs.
|
|
|
|
|
|
9.18 2010-11-02
|
|
-------------------------
|
|
- New small SFX module for installers (C/Util/SfxSetup).
|
|
|
|
|
|
9.17 2010-10-04
|
|
-------------------------
|
|
- IStream.h::IOutStream::
|
|
STDMETHOD(SetSize)(Int64 newSize) PURE;
|
|
was changed to
|
|
STDMETHOD(SetSize)(UInt64 newSize) PURE;
|
|
|
|
|
|
9.09 2009-12-12
|
|
-------------------------
|
|
- The bug was fixed:
|
|
Utf16_To_Utf8 funstions in UTFConvert.cpp and 7zMain.c
|
|
incorrectly converted surrogate characters (the code >= 0x10000) to UTF-8.
|
|
|
|
|
|
9.05 2009-07-05
|
|
-------------------------

|
|
|
|
|

|
-------------------------
|
|
- ICoder.h: NCoderPropID::EEnum values were changed
|
|
|
|
|
|
9.02 2009-04-23
|
|
-------------------------
|
|
- Bug was fixed: if swap2 filter was requests at compression,
|
|
7-zip used swap4 filter instead (but id was swap2), so archives were incorrect.
|
|
|
|
4.61 2008-11-23
|
|
-------------------------
|
|
- Bug in ver. 4.58+ was fixed:
|
|
7-Zip didn't use any -m* switch after -mtc, -mcl or -mcu for .zip archives.
|
|
- Bug in .CAB code was fixed. 7-Zip didn't show some empty files,
|
|
if .CAB archive contains more than one empty file.
|
|
|
|
|
|
4.59 2008-07-27
|
|
-------------------------
|
|
- Bug was fixed:
|
|
LZMA Encoder in fast compression mode could access memory outside of
|
|
allocated range in some rare cases.
|
|
|
|
|
|
4.59 alpha 2008-05-30
|
|
-------------------------
|
|
- BUGS was fixed:
|
|
7zOut.cpp: 7-Zip incorrectly wrote size of property records in some cases.
|
|
7zIn.cpp: 7-Zip incorrectly work with archive, containg archive properties.
|
|
|
|
4.58 alpha 9 2008-04-29
|
|
-------------------------
|
|
- BUG was fixed: 7-Zip showed incorrect timestamps in ISO files.
|
|
|
|
|
|
4.58 alpha 8 2008-04-15
|
|
-------------------------
|
|
- BUG in 4.58 alpha 5/6/7 was fixed:
|
|
LZMA encoder worked incorrectly, if lp != 0.
|
|
- Unicode (UTF-8) support for filenames in .ZIP archives. Now there are 3 modes:
|
|
1) Default mode: 7-Zip uses UTF-8, if the local code page doesn't contain required symbols.
|
|
2) -mcu switch: 7-Zip uses UTF-8, if there are non-ASCII symbols.
|
|
3) -mcl switch: 7-Zip uses local code page.
|
|
- Now it's possible to use -mSW- and -mSW+ switches instead of -mSW=off and -mSW=on
|
|
|
|
|
|
4.58 alpha 7 2008-04-08
|
|
-------------------------
|
|
- BUG was fixed: BZip2Encoder and BZip2Decoder used CEvent objects without
|
|
creating, when BZip2 code was called with one thread (with -mmt1 switch or with
|
|
default switches on single thread CPU).
|
|
- .lzma support.
|
|
- RPM and NSIS support was improved.
|
|
- LZMA now stores only (2 << n) or (3 << n) dictionary size value to LZMA properties.
|
|
|
|
|
|
4.58 alpha 6 2008-03-27
|
|
-------------------------
|
|
- NTFS time extra in ZIP.
|
|
- New item property - kpidTimeType - VT_UI4 (0 - NTFS, 1 - Unix, 2 - DOS).
|
|
- Static CRC table is not required now for Lzma Encoder (in Lz MatchFinder).
|
|
|
|
|
|
4.58 alpha 5 2008-03-19
|
|
-------------------------
|
|
- Creation time (-mtc switch) for .7z archives
|
|
- LZMA encoder was converted to ANSI-C
|
|
|
|
|
|
4.58 alpha 3 2008-02-25
|
|
-------------------------
|
|
- Speed optimizations for LZMA decoding. Now it uses C code instead of C++.
|
|
- 7-Zip now has 128 MB dictionary limit for 32-bit version:
|
|
It's for speed optimization: kNumLogBits = 9 + sizeof(size_t) / 2;
|
|
- TAR: 'D' link flag support.
|
|
- 7-Zip now can unpack multivolume RAR archives created with
|
|
"old style volume names" scheme (-vn switch) and names *.001, *.002, ...
|
|
- Fixed bugs:
|
|
- 7-Zip FM could not copy / move files to root network folders like \\COMPNAME\FOLDERNAME\
|
|
In case of move it removed original files.
|
|
- SFX-WIN: if there are errors, it still could return 0.
|
|
- ZIP (.XPS file) isZip64 && thisDiskNumber16 == 0xFFFF.
|
|
- ZIP name updating:
|
|
If zip file contains extra field and you try to change properties of files,
|
|
7-zip tries to delete all extra fileds (except for WzAES).
|
|
And that code could hang.
|
|
- 7-Zip GUI didn't suggest BZip2 dictionary size used in previous run.
|
|
- If creation time stamp was included in .RAR archive, 7-zip used creation time stamp
|
|
as modification time stamp.
|
|
|
|
4.58 alpha 2 2007-12-31
|
|
-------------------------
|
|
- Small changes in Deflate and LZMA compression.
|
|

|
|

it was:
|
|
data++
|
|
fixed version:
|
