__cpuid (function == 4) requires subfunction number in ECX.
MSDN: The __cpuid intrinsic clears the ECX register before calling the cpuid instruction.
__cpuid() in new MSVC clears ECX.
__cpuid() in old MSVC (14.00) doesn't clear ECX
We still can use __cpuid for low (function) values that don't require ECX,
but __cpuid() in old MSVC will be incorrect for some function values: (function == 4).
So here we use the hack for old MSVC to send (subFunction) in ECX register to cpuid instruction,
where ECX value is first parameter for FAST_CALL / NO_INLINE function,
So the caller of MY__cpuidex_HACK() sets ECX as subFunction, and
old MSVC for __cpuid() doesn't change ECX and cpuid instruction gets (subFunction) value.
DON'T remove MY_NO_INLINE and MY_FAST_CALL for MY__cpuidex_HACK() !!!

LzmaDec_TryDummy() was called before to exclude LITERAL and MATCH-REP cases.

is not END_OF_PAYALOAD_MARKER, then function returns error code.

The first LZMA symbol will be decoded in any case.
All main checks for limits are at the end of main loop,
It decodes additional LZMA-symbols while (p->buf < bufLimit && dicPos < limit),
RangeCoder is still without last normalization when (p->buf < bufLimit) is being checked.
But if (p->buf < bufLimit), the caller provided at least (LZMA_REQUIRED_INPUT_MAX + 1) bytes for
next iteration before limit (bufLimit + LZMA_REQUIRED_INPUT_MAX),
that is enough for worst case LZMA symbol with one additional RangeCoder normalization for one bit.
So that function never reads bufLimit [LZMA_REQUIRED_INPUT_MAX] byte.

RangeCoder is normalized

LZMA supports optional end_marker.

That additional LZMA-Symbol can require up to LZMA_REQUIRED_INPUT_MAX bytes in input stream.
When the decoder reaches dicLimit, it looks (finishMode) parameter:
if (finishMode == LZMA_FINISH_ANY), the decoder doesn't lookahead
if (finishMode != LZMA_FINISH_ANY), the decoder lookahead, if end_marker is possible for current position
When the decoder lookahead, and the lookahead symbol is not end_marker, we have two ways:
1) Strict mode (default) : the decoder returns SZ_ERROR_DATA.
2) The relaxed mode (alternative mode) : we could return SZ_OK, and the caller
must check (status) value. The caller can show the error,

PPMD code can write full CPpmd_State structure data to CPpmd*_Context
at (byte offset = 2) instead of some fields of original CPpmd*_Context structure.
If we use pointers to different types, but that point to shared
memory space, we can have aliasing problem (strict aliasing).
XLC compiler in -O2 mode can change the order of memory write instructions
in relation to read instructions, if we have use pointers to different types.
To solve that aliasing problem we use combined CPpmd*_Context structure
with unions that contain the fields from both structures:
the original CPpmd*_Context and CPpmd_State.
So we can access the fields from both structures via one pointer,
and the compiler doesn't change the order of write instructions
in relation to read instructions.
If we don't use memory write instructions to shared memory in
some local code, and we use only reading instructions (read only),
then probably it's safe to use pointers to different types for reading.

7-Zip method IDs for 7z and xz archives
---------------------------------------
Version: 18.06
Date: 2018-06-30
Each compression or crypto method in 7z is associated with unique binary value (ID).
The length of ID in bytes is arbitrary but it can not exceed 63 bits (8 bytes).
xz and 7z formats use same ID map.
If you want to add some new ID, you have two ways:
1) Write request for allocating IDs to 7-Zip developers.
2) Generate 8-bytes ID:
3F ZZ ZZ ZZ ZZ ZZ MM MM
3F - Prefix for random IDs (1 byte)
ZZ ZZ ZZ ZZ ZZ - Developer ID (5 bytes). Use real random bytes.
MM MM - Method ID (2 bytes)
You can notify 7-Zip developers about your Developer ID / Method ID.
Note: Use new ID, if old codec can not decode data encoded with new version.

7-Zip for installers 9.38
-------------------------
7-Zip is a file archiver for Windows NT/2000/2003/2008/XP/Vista/7/8/10.
7-Zip for installers is part of LZMA SDK.
LZMA SDK is written and placed in the public domain by Igor Pavlov.
It's allowed to join 7-Zip SFX module with another software.
It's allowed to change resources of 7-Zip's SFX modules.
HOW to use
-----------
7zr.exe is reduced version of 7za.exe of 7-Zip.
7zr.exe supports only format with these codecs: LZMA, LZMA2, BCJ, BCJ2, ARM, Copy.
Example of compressing command for installation packages:
7zr a archive.7z files
7zSD.sfx is SFX module for installers. 7zSD.sfx uses msvcrt.dll.
SFX modules for installers allow to create installation program.
Such module extracts archive to temp folder and then runs specified program and removes
temp files after program finishing. Self-extract archive for installers must be created
as joining 3 files: SFX_Module, Installer_Config, 7z_Archive.
Installer_Config is optional file. You can use the following command to create installer
self-extract archive:
copy /b 7zSD.sfx + config.txt + archive.7z archive.exe
The smallest installation package size can be achieved, if installation files was
uncompressed before including to 7z archive.
-y switch for installer module (at runtime) specifies quiet mode for extracting.
Installer Config file format
~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Config file contains commands for Installer. File begins from string
;!@Install@!UTF-8! and ends with ;!@InstallEnd@!. File must be written
in UTF-8 encoding. File contains string pairs:
ID_String="Value"
ID_String Description
Title Title for messages
BeginPrompt Begin Prompt message
Progress Value can be "yes" or "no". Default value is "yes".
RunProgram Command for executing. Default value is "setup.exe".
Substring %%T will be replaced with path to temporary
folder, where files were extracted
Directory Directory prefix for "RunProgram". Default value is ".\\"
ExecuteFile Name of file for executing
ExecuteParameters Parameters for "ExecuteFile"
You can omit any string pair.
There are two ways to run program: RunProgram and ExecuteFile.
Use RunProgram, if you want to run some program from .7z archive.
Use ExecuteFile, if you want to open some document from .7z archive or
if you want to execute some command from Windows.
If you use RunProgram and if you specify empty directory prefix: Directory="",
the system searches for the executable file in the following sequence:
1. The directory from which the application (installer) loaded.
2. The temporary folder, where files were extracted.
3. The Windows system directory.
Config file Examples
~~~~~~~~~~~~~~~~~~~~
;!@Install@!UTF-8!
Title="7-Zip 4.00"
BeginPrompt="Do you want to install the 7-Zip 4.00?"
RunProgram="setup.exe"
;!@InstallEnd@!
;!@Install@!UTF-8!
Title="7-Zip 4.00"
BeginPrompt="Do you want to install the 7-Zip 4.00?"
ExecuteFile="7zip.msi"
;!@InstallEnd@!
;!@Install@!UTF-8!
Title="7-Zip 4.01 Update"
BeginPrompt="Do you want to install the 7-Zip 4.01 Update?"
ExecuteFile="msiexec.exe"
ExecuteParameters="/i 7zip.msi REINSTALL=ALL REINSTALLMODE=vomus"
;!@InstallEnd@!
Small SFX modules for installers
--------------------------------
7zS2.sfx - small SFX module (GUI version)
7zS2con.sfx - small SFX module (Console version)
Small SFX modules support this codecs: LZMA, LZMA2, BCJ, BCJ2, ARM, COPY
Small SFX module is similar to common SFX module for installers.
The difference (what's new in small version):
- Smaller size (30 KB vs 100 KB)
- C source code instead of Ñ++
- No installer Configuration file
- No extracting progress window
- It decompresses solid 7z blocks (it can be whole 7z archive) to RAM.
So user that calls SFX installer must have free RAM of size of largest
solid 7z block (size of 7z archive at simplest case).
How to use
----------
copy /b 7zS2.sfx + archive.7z sfx.exe
When you run installer sfx module (sfx.exe)
1) It creates "7zNNNNNNNN" temp folder in system temp folder.
2) It extracts .7z archive to that folder
3) It executes one file from "7zNNNNNNNN" temp folder.
4) It removes "7zNNNNNNNN" temp folder
You can send parameters to installer, and installer will transfer them to extracted .exe file.
Small SFX uses 3 levels of priorities to select file to execute:
1) Files in root folder have higher priority than files in subfolders.
2) File extension priorities (from high to low priority order):
bat, cmd, exe, inf, msi, cab (under Windows CE), html, htm
3) File name priorities (from high to low priority order):
setup, install, run, start
Windows CE (ARM) version of 7zS2.sfx is included to 7-Zip for Windows Mobile package.
Examples
--------
1) To create compressed console 7-Zip:
7zr a c.7z 7z.exe 7z.dll -mx
copy /b 7zS2con.sfx + c.7z 7zCompr.exe
7zCompr.exe b -md22
2) To create compressed GUI 7-Zip:
7zr a g.7z 7zg.exe 7z.dll -mx
copy /b 7zS2.sfx + g.7z 7zgCompr.exe
7zgCompr.exe b -md22
3) To open some file:
7zr a h.7z readme.txt -mx
copy /b 7zS2.sfx + h.7z 7zTxt.exe
7zTxt.exe

HISTORY of the LZMA SDK
-----------------------
21.02 alpha 2021-05-06
-------------------------
- The command line version of 7-Zip for macOS was released.
- The speed for LZMA and LZMA2 decompression in arm64 versions for macOS and Linux
was increased by 20%-60%.
21.01 alpha 2021-03-09
-------------------------
- The command line version of 7-Zip for Linux was released.
- The improvements for speed of ARM64 version using hardware CPU instructions
for AES, CRC-32, SHA-1 and SHA-256.
- Some bugs were fixed.
20.02 alpha 2020-08-08
-------------------------
- The default number of LZMA2 chunks per solid block in 7z archive was increased to 64.
It allows to increase the compression speed for big 7z archives, if there is a big number
of CPU cores and threads.
- The speed of PPMd compressing/decompressing was increased for 7z archives.
- The new -ssp switch. If the switch -ssp is specified, 7-Zip doesn't allow the system
to modify "Last Access Time" property of source files for archiving and hashing operations.
- Some bugs were fixed.
20.00 alpha 2020-02-06
-------------------------
- 7-Zip now supports new optional match finders for LZMA/LZMA2 compression: bt5 and hc5,
that can work faster than bt4 and hc4 match finders for the data with big redundancy.
- The compression ratio was improved for Fast and Fastest compression levels with the
following default settings:
- Fastest level (-mx1) : hc5 match finder with 256 KB dictionary.
- Fast level (-mx3) : hc5 match finder with 4 MB dictionary.
- Minor speed optimizations in multithreaded LZMA/LZMA2 compression for Normal/Maximum/Ultra
compression levels.
19.00 2019-02-21
-------------------------
- Encryption strength for 7z archives was increased:
the size of random initialization vector was increased from 64-bit to 128-bit,
and the pseudo-random number generator was improved.
- The bug in 7zIn.c code was fixed.
18.06 2018-12-30
-------------------------
- The speed for LZMA/LZMA2 compressing was increased by 3-10%,
and there are minor changes in compression ratio.
- Some bugs were fixed.
- The bug in 7-Zip 18.02-18.05 was fixed:
There was memory leak in multithreading xz decoder - XzDecMt_Decode(),
if xz stream contains only one block.
- The changes for MSVS compiler makefiles:
- the makefiles now use "PLATFORM" macroname with values (x64, x86, arm64)
instead of "CPU" macroname with values (AMD64, ARM64).
- the makefiles by default now use static version of the run-time library.
18.05 2018-04-30
-------------------------
- The speed for LZMA/LZMA2 compressing was increased
by 8% for fastest/fast compression levels and
by 3% for normal/maximum compression levels.
- Previous versions of 7-Zip could work incorrectly in "Large memory pages" mode in
Windows 10 because of some BUG with "Large Pages" in Windows 10.
Now 7-Zip doesn't use "Large Pages" on Windows 10 up to revision 1709 (16299).
- The BUG was fixed in Lzma2Enc.c
Lzma2Enc_Encode2() function worked incorretly,
if (inStream == NULL) and the number of block threads is more than 1.
18.03 beta 2018-03-04
-------------------------
- Asm\x86\LzmaDecOpt.asm: new optimized LZMA decoder written in asm
for x64 with about 30% higher speed than main version of LZMA decoder written in C.
- The speed for single-thread LZMA/LZMA2 decoder written in C was increased by 3%.
- 7-Zip now can use multi-threading for 7z/LZMA2 decoding,
if there are multiple independent data chunks in LZMA2 stream.
- 7-Zip now can use multi-threading for xz decoding,
if there are multiple blocks in xz stream.
18.01 2019-01-28
-------------------------
- The BUG in 17.01 - 18.00 beta was fixed:
XzDec.c : random block unpacking and XzUnpacker_IsBlockFinished()
didn't work correctly for xz archives without checksum (CRC).
18.00 beta 2019-01-10
-------------------------
- The BUG in xz encoder was fixed:
There was memory leak of 16 KB for each file compressed with
xz compression method, if additional filter was used.
17.01 beta 2017-08-28
-------------------------
- Minor speed optimization for LZMA2 (xz and 7z) multi-threading compression.
7-Zip now uses additional memory buffers for multi-block LZMA2 compression.
CPU utilization was slightly improved.
- 7-zip now creates multi-block xz archives by default. Block size can be
specified with -ms[Size]{m|g} switch.
- xz decoder now can unpack random block from multi-block xz archives.
- 7-Zip command line: @listfile now doesn't work after -- switch.
Use -i@listfile before -- switch instead.

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 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.

LZMA SDK 21.02
--------------
LZMA SDK provides the documentation, samples, header files,
libraries, and tools you need to develop applications that
use 7z / LZMA / LZMA2 / XZ compression.
LZMA is an improved version of famous LZ77 compression algorithm.
It was improved in way of maximum increasing of compression ratio,
keeping high decompression speed and low memory requirements for
decompressing.
LZMA2 is a LZMA based compression method. LZMA2 provides better
multithreading support for compression than LZMA and some other improvements.
7z is a file format for data compression and file archiving.
7z is a main file format for 7-Zip compression program (www.7-zip.org).
7z format supports different compression methods: LZMA, LZMA2 and others.

LZMA features
-------------
- Variable dictionary size (up to 1 GB)
- Estimated compressing speed: about 2 MB/s on 2 GHz CPU
- Estimated decompressing speed:
- 20-30 MB/s on modern 2 GHz cpu
- 1-2 MB/s on 200 MHz simple RISC cpu: (ARM, MIPS, PowerPC)
- Small memory requirements for decompressing (16 KB + DictionarySize)
- Small code size for decompressing: 5-8 KB
LZMA decoder uses only integer operations and can be
implemented in any modern 32-bit CPU (or on 16-bit CPU with some conditions).
Some critical operations that affect the speed of LZMA decompression:
1) 32*16 bit integer multiply
2) Mispredicted branches (penalty mostly depends from pipeline length)
3) 32-bit shift and arithmetic operations
The speed of LZMA decompressing mostly depends from CPU speed.
Memory speed has no big meaning. But if your CPU has small data cache,
overall weight of memory speed will slightly increase.
How To Use
----------
Using LZMA encoder/decoder executable
--------------------------------------
Usage: LZMA <e|d> inputFile outputFile [<switches>...]
e: encode file
d: decode file
b: Benchmark. There are two tests: compressing and decompressing
with LZMA method. Benchmark shows rating in MIPS (million
instructions per second). Rating value is calculated from
measured speed and it is normalized with Intel's Core 2 results.
Also Benchmark checks possible hardware errors (RAM
errors in most cases). Benchmark uses these settings:
(-a1, -d21, -fb32, -mfbt4). You can change only -d parameter.
Also you can change the number of iterations. Example for 30 iterations:
LZMA b 30
Default number of iterations is 10.
<Switches>
-a{N}: set compression mode 0 = fast, 1 = normal
default: 1 (normal)
d{N}: Sets Dictionary size - [0, 30], default: 23 (8MB)
The maximum value for dictionary size is 1 GB = 2^30 bytes.
Dictionary size is calculated as DictionarySize = 2^N bytes.
For decompressing file compressed by LZMA method with dictionary
size D = 2^N you need about D bytes of memory (RAM).
-fb{N}: set number of fast bytes - [5, 273], default: 128
Usually big number gives a little bit better compression ratio
and slower compression process.
-lc{N}: set number of literal context bits - [0, 8], default: 3
Sometimes lc=4 gives gain for big files.
-lp{N}: set number of literal pos bits - [0, 4], default: 0
lp switch is intended for periodical data when period is
equal 2^N. For example, for 32-bit (4 bytes)
periodical data you can use lp=2. Often it's better to set lc0,
if you change lp switch.
-pb{N}: set number of pos bits - [0, 4], default: 2
pb switch is intended for periodical data
when period is equal 2^N.
-mf{MF_ID}: set Match Finder. Default: bt4.
Algorithms from hc* group doesn't provide good compression
ratio, but they often works pretty fast in combination with
fast mode (-a0).
Memory requirements depend from dictionary size
(parameter "d" in table below).
MF_ID Memory Description
bt2 d * 9.5 + 4MB Binary Tree with 2 bytes hashing.
bt3 d * 11.5 + 4MB Binary Tree with 3 bytes hashing.
bt4 d * 11.5 + 4MB Binary Tree with 4 bytes hashing.
hc4 d * 7.5 + 4MB Hash Chain with 4 bytes hashing.
-eos: write End Of Stream marker. By default LZMA doesn't write
eos marker, since LZMA decoder knows uncompressed size
stored in .lzma file header.
-si: Read data from stdin (it will write End Of Stream marker).
-so: Write data to stdout
Examples:
1) LZMA e file.bin file.lzma -d16 -lc0
compresses file.bin to file.lzma with 64 KB dictionary (2^16=64K)
and 0 literal context bits. -lc0 allows to reduce memory requirements
for decompression.
2) LZMA e file.bin file.lzma -lc0 -lp2
compresses file.bin to file.lzma with settings suitable
for 32-bit periodical data (for example, ARM or MIPS code).
3) LZMA d file.lzma file.bin
decompresses file.lzma to file.bin.
Compression ratio hints
-----------------------
Recommendations
---------------
To increase the compression ratio for LZMA compressing it's desirable
to have aligned data (if it's possible) and also it's desirable to locate
data in such order, where code is grouped in one place and data is
grouped in other place (it's better than such mixing: code, data, code,
data, ...).
Filters
-------
You can increase the compression ratio for some data types, using
special filters before compressing. For example, it's possible to
increase the compression ratio on 5-10% for code for those CPU ISAs:
x86, IA-64, ARM, ARM-Thumb, PowerPC, SPARC.
You can find C source code of such filters in C/Bra*.* files
You can check the compression ratio gain of these filters with such
7-Zip commands (example for ARM code):
No filter:
7z a a1.7z a.bin -m0=lzma
With filter for little-endian ARM code:
7z a a2.7z a.bin -m0=arm -m1=lzma
It works in such manner:
Compressing = Filter_encoding + LZMA_encoding
Decompressing = LZMA_decoding + Filter_decoding
Compressing and decompressing speed of such filters is very high,
so it will not increase decompressing time too much.
Moreover, it reduces decompression time for LZMA_decoding,
since compression ratio with filtering is higher.
These filters convert CALL (calling procedure) instructions
from relative offsets to absolute addresses, so such data becomes more
compressible.
For some ISAs (for example, for MIPS) it's impossible to get gain from such filter.

LZMA compression
----------------
Version: 9.35
This file describes LZMA encoding and decoding functions written in C language.
LZMA is an improved version of famous LZ77 compression algorithm.
It was improved in way of maximum increasing of compression ratio,
keeping high decompression speed and low memory requirements for
decompressing.
Note: you can read also LZMA Specification (lzma-specification.txt from LZMA SDK)
Also you can look source code for LZMA encoding and decoding:
C/Util/Lzma/LzmaUtil.c
LZMA compressed file format
---------------------------
Offset Size Description
0 1 Special LZMA properties (lc,lp, pb in encoded form)
1 4 Dictionary size (little endian)
5 8 Uncompressed size (little endian). -1 means unknown size
13 Compressed data
ANSI-C LZMA Decoder
~~~~~~~~~~~~~~~~~~~
Please note that interfaces for ANSI-C code were changed in LZMA SDK 4.58.
If you want to use old interfaces you can download previous version of LZMA SDK
from sourceforge.net site.
To use ANSI-C LZMA Decoder you need the following files:
1) LzmaDec.h + LzmaDec.c + 7zTypes.h + Precomp.h + Compiler.h
Look example code:
C/Util/Lzma/LzmaUtil.c
Memory requirements for LZMA decoding
-------------------------------------
Stack usage of LZMA decoding function for local variables is not
larger than 200-400 bytes.
LZMA Decoder uses dictionary buffer and internal state structure.
Internal state structure consumes
state_size = (4 + (1.5 << (lc + lp))) KB
by default (lc=3, lp=0), state_size = 16 KB.
How To decompress data
----------------------
LZMA Decoder (ANSI-C version) now supports 2 interfaces:
1) Single-call Decompressing
2) Multi-call State Decompressing (zlib-like interface)
You must use external allocator:
Example:
void *SzAlloc(void *p, size_t size) { p = p; return malloc(size); }
void SzFree(void *p, void *address) { p = p; free(address); }
ISzAlloc alloc = { SzAlloc, SzFree };
You can use p = p; operator to disable compiler warnings.
Single-call Decompressing
-------------------------
When to use: RAM->RAM decompressing
Compile files: LzmaDec.h + LzmaDec.c + 7zTypes.h
Compile defines: no defines
Memory Requirements:
- Input buffer: compressed size
- Output buffer: uncompressed size
- LZMA Internal Structures: state_size (16 KB for default settings)
Interface:
int LzmaDecode(Byte *dest, SizeT *destLen, const Byte *src, SizeT *srcLen,
const Byte *propData, unsigned propSize, ELzmaFinishMode finishMode,
ELzmaStatus *status, ISzAlloc *alloc);
In:
dest - output data
destLen - output data size
src - input data
srcLen - input data size
propData - LZMA properties (5 bytes)
propSize - size of propData buffer (5 bytes)
finishMode - It has meaning only if the decoding reaches output limit (*destLen).
LZMA_FINISH_ANY - Decode just destLen bytes.
LZMA_FINISH_END - Stream must be finished after (*destLen).
You can use LZMA_FINISH_END, when you know that
current output buffer covers last bytes of stream.
alloc - Memory allocator.
Out:
destLen - processed output size
srcLen - processed input size
Output:
SZ_OK
status:
LZMA_STATUS_FINISHED_WITH_MARK
LZMA_STATUS_NOT_FINISHED
LZMA_STATUS_MAYBE_FINISHED_WITHOUT_MARK
SZ_ERROR_DATA - Data error
SZ_ERROR_MEM - Memory allocation error
SZ_ERROR_UNSUPPORTED - Unsupported properties
SZ_ERROR_INPUT_EOF - It needs more bytes in input buffer (src).
If LZMA decoder sees end_marker before reaching output limit, it returns OK result,
and output value of destLen will be less than output buffer size limit.
You can use multiple checks to test data integrity after full decompression:
1) Check Result and "status" variable.
2) Check that output(destLen) = uncompressedSize, if you know real uncompressedSize.
3) Check that output(srcLen) = compressedSize, if you know real compressedSize.
You must use correct finish mode in that case. */
Multi-call State Decompressing (zlib-like interface)
----------------------------------------------------
When to use: file->file decompressing
Compile files: LzmaDec.h + LzmaDec.c + 7zTypes.h
Memory Requirements:
- Buffer for input stream: any size (for example, 16 KB)
- Buffer for output stream: any size (for example, 16 KB)
- LZMA Internal Structures: state_size (16 KB for default settings)
- LZMA dictionary (dictionary size is encoded in LZMA properties header)
1) read LZMA properties (5 bytes) and uncompressed size (8 bytes, little-endian) to header:
unsigned char header[LZMA_PROPS_SIZE + 8];
ReadFile(inFile, header, sizeof(header)
2) Allocate CLzmaDec structures (state + dictionary) using LZMA properties
CLzmaDec state;
LzmaDec_Constr(&state);
res = LzmaDec_Allocate(&state, header, LZMA_PROPS_SIZE, &g_Alloc);
if (res != SZ_OK)
return res;
3) Init LzmaDec structure before any new LZMA stream. And call LzmaDec_DecodeToBuf in loop
LzmaDec_Init(&state);
for (;;)
{
...
int res = LzmaDec_DecodeToBuf(CLzmaDec *p, Byte *dest, SizeT *destLen,
const Byte *src, SizeT *srcLen, ELzmaFinishMode finishMode);
...
}
4) Free all allocated structures
LzmaDec_Free(&state, &g_Alloc);
Look example code:
C/Util/Lzma/LzmaUtil.c
How To compress data
--------------------
Compile files:
7zTypes.h
Threads.h
LzmaEnc.h
LzmaEnc.c
LzFind.h
LzFind.c
LzFindMt.h
LzFindMt.c
LzHash.h
Memory Requirements:
- (dictSize * 11.5 + 6 MB) + state_size
Lzma Encoder can use two memory allocators:
1) alloc - for small arrays.
2) allocBig - for big arrays.
For example, you can use Large RAM Pages (2 MB) in allocBig allocator for
better compression speed. Note that Windows has bad implementation for
Large RAM Pages.
It's OK to use same allocator for alloc and allocBig.
Single-call Compression with callbacks
--------------------------------------
Look example code:
C/Util/Lzma/LzmaUtil.c
When to use: file->file compressing
1) you must implement callback structures for interfaces:
ISeqInStream
ISeqOutStream
ICompressProgress
ISzAlloc
static void *SzAlloc(void *p, size_t size) { p = p; return MyAlloc(size); }
static void SzFree(void *p, void *address) { p = p; MyFree(address); }
static ISzAlloc g_Alloc = { SzAlloc, SzFree };
CFileSeqInStream inStream;
CFileSeqOutStream outStream;
inStream.funcTable.Read = MyRead;
inStream.file = inFile;
outStream.funcTable.Write = MyWrite;
outStream.file = outFile;
2) Create CLzmaEncHandle object;
CLzmaEncHandle enc;
enc = LzmaEnc_Create(&g_Alloc);
if (enc == 0)
return SZ_ERROR_MEM;
3) initialize CLzmaEncProps properties;
LzmaEncProps_Init(&props);
Then you can change some properties in that structure.
4) Send LZMA properties to LZMA Encoder
res = LzmaEnc_SetProps(enc, &props);
5) Write encoded properties to header
Byte header[LZMA_PROPS_SIZE + 8];
size_t headerSize = LZMA_PROPS_SIZE;
UInt64 fileSize;
int i;
res = LzmaEnc_WriteProperties(enc, header, &headerSize);
fileSize = MyGetFileLength(inFile);
for (i = 0; i < 8; i++)
header[headerSize++] = (Byte)(fileSize >> (8 * i));
MyWriteFileAndCheck(outFile, header, headerSize)
6) Call encoding function:
res = LzmaEnc_Encode(enc, &outStream.funcTable, &inStream.funcTable,
NULL, &g_Alloc, &g_Alloc);
7) Destroy LZMA Encoder Object
LzmaEnc_Destroy(enc, &g_Alloc, &g_Alloc);
If callback function return some error code, LzmaEnc_Encode also returns that code
or it can return the code like SZ_ERROR_READ, SZ_ERROR_WRITE or SZ_ERROR_PROGRESS.
Single-call RAM->RAM Compression
--------------------------------
Single-call RAM->RAM Compression is similar to Compression with callbacks,
but you provide pointers to buffers instead of pointers to stream callbacks:
SRes LzmaEncode(Byte *dest, SizeT *destLen, const Byte *src, SizeT srcLen,
const CLzmaEncProps *props, Byte *propsEncoded, SizeT *propsSize, int writeEndMark,
ICompressProgress *progress, ISzAlloc *alloc, ISzAlloc *allocBig);
Return code:
SZ_OK - OK
SZ_ERROR_MEM - Memory allocation error
SZ_ERROR_PARAM - Incorrect paramater
SZ_ERROR_OUTPUT_EOF - output buffer overflow
SZ_ERROR_THREAD - errors in multithreading functions (only for Mt version)
Defines
-------
_LZMA_SIZE_OPT - Enable some optimizations in LZMA Decoder to get smaller executable code.
_LZMA_PROB32 - It can increase the speed on some 32-bit CPUs, but memory usage for
some structures will be doubled in that case.
_LZMA_UINT32_IS_ULONG - Define it if int is 16-bit on your compiler and long is 32-bit.
_LZMA_NO_SYSTEM_SIZE_T - Define it if you don't want to use size_t type.
_7ZIP_PPMD_SUPPPORT - Define it if you don't want to support PPMD method in AMSI-C .7z decoder.
C++ LZMA Encoder/Decoder
~~~~~~~~~~~~~~~~~~~~~~~~
C++ LZMA code use COM-like interfaces. So if you want to use it,
you can study basics of COM/OLE.
C++ LZMA code is just wrapper over ANSI-C code.
C++ Notes
~~~~~~~~~~~~~~~~~~~~~~~~
If you use some C++ code folders in 7-Zip (for example, C++ code for .7z handling),
you must check that you correctly work with "new" operator.
7-Zip can be compiled with MSVC 6.0 that doesn't throw "exception" from "new" operator.
So 7-Zip uses "CPP\Common\NewHandler.cpp" that redefines "new" operator:
operator new(size_t size)
{
void *p = ::malloc(size);
if (p == 0)
throw CNewException();
return p;
}
If you use MSCV that throws exception for "new" operator, you can compile without
"NewHandler.cpp". So standard exception will be used. Actually some code of
7-Zip catches any exception in internal code and converts it to HRESULT code.
So you don't need to catch CNewException, if you call COM interfaces of 7-Zip.
