+7z ANSI-C Decoder 4.23

+----------------------

+

+7z ANSI-C Decoder 4.23 Copyright (C) 1999-2005 Igor Pavlov

+

+7z ANSI-C provides 7z/LZMA decoding.

+7z ANSI-C version is simplified version ported from C++ code.

+

+LZMA is default and general compression method of 7z format

+in 7-Zip compression program (www.7-zip.org). LZMA provides high 

+compression ratio and very fast decompression.

+

+

+LICENSE

+-------

+

+Read lzma.txt for information about license.

+

+

+Files

+---------------------

+

+7zAlloc.*    - Allocate and Free

+7zBuffer.*   - Buffer structure

+7zCrc.*      - CRC32 code

+7zDecode.*   - Low level memory->memory decoding

+7zExtract.*  - High level stream->memory decoding

+7zHeader.*   - .7z format constants

+7zIn.*       - .7z archive opening

+7zItem.*     - .7z structures

+7zMain.c     - Test application

+7zMethodID.* - MethodID structure

+7zTypes.h    - Base types and constants

+

+

+How To Use

+----------

+

+You must download 7-Zip program from www.7-zip.org.

+

+You can create .7z archive with 7z.exe or 7za.exe:

+

+  7za.exe a archive.7z *.htm -r -mx -m0fb=255 -mf=off

+

+If you have big number of files in archive, and you need fast extracting, 

+you can use partly-solid archives:

+  

+  7za.exe a archive.7z *.htm -ms=512K -r -mx -m0fb=255 -m0d=512K -mf=off

+

+In that example 7-Zip will use 512KB solid blocks. So it needs to decompress only 

+512KB for extracting one file from such archive.

+

+

+Limitations of current version of 7z ANSI-C Decoder

+---------------------------------------------------

+

+ - It reads only "FileName", "Size", and "CRC" information for each file in archive.

+ - It supports only LZMA and Copy (no compression) methods.

+ - It converts original UTF-16 Unicode file names to UTF-8 Unicode file names.

+ 

+These limitations will be fixed in future versions.

+

+

+Using 7z ANSI-C Decoder Test application:

+-----------------------------------------

+

+Usage: 7zDec <command> <archive_name>

+

+<Command>:

+  e: Extract files from archive

+  l: List contents of archive

+  t: Test integrity of archive

+

+Example: 

+

+  7zDec l archive.7z

+

+lists contents of archive.7z

+

+  7zDec e archive.7z

+

+extracts files from archive.7z to current folder.

+

+

+How to use .7z Decoder

+----------------------

+

+.7z Decoder can be compiled in one of two modes:

+

+1) Default mode. In that mode 7z Decoder will read full compressed 

+   block to RAM before decompressing.

+  

+2) Mode with defined _LZMA_IN_CB. In that mode 7z Decoder can read

+   compressed block by parts. And you can specify desired buffer size. 

+   So memory requirements can be reduced. But decompressing speed will 

+   be 5-10% lower and code size is slightly larger.

+

+   

+Memory allocation

+~~~~~~~~~~~~~~~~~

+

+7z Decoder uses two memory pools:

+1) Temporary pool

+2) Main pool

+Such scheme can allow you to avoid fragmentation of allocated blocks.

+

+Steps for using 7z decoder

+--------------------------

+

+Use code at 7zMain.c as example.

+

+1) Declare variables:

+  inStream                     /* implements ISzInStream interface */

+  CArchiveDatabaseEx db;       /* 7z archive database structure */

+  ISzAlloc allocImp;           /* memory functions for main pool */

+  ISzAlloc allocTempImp;       /* memory functions for temporary pool */

+

+2) call InitCrcTable(); function to initialize CRC structures.

+

+3) call SzArDbExInit(&db); function to initialize db structures.

+

+4) call SzArchiveOpen(inStream, &db, &allocMain, &allocTemp) to open archive

+

+This function opens archive "inStream" and reads headers to "db".

+All items in "db" will be allocated with "allocMain" functions.

+SzArchiveOpen function allocates and frees temporary structures by "allocTemp" functions.

+

+5) List items or Extract items

+

+  Listing code:

+  ~~~~~~~~~~~~~

+    {

+      UInt32 i;

+      for (i = 0; i < db.Database.NumFiles; i++)

+      {

+        CFileItem *f = db.Database.Files + i;

+        printf("%10d  %s\n", (int)f->Size, f->Name);

+      }

+    }

+

+  Extracting code:

+  ~~~~~~~~~~~~~~~~

+

+  SZ_RESULT SzExtract(

+    ISzInStream *inStream, 

+    CArchiveDatabaseEx *db,

+    UInt32 fileIndex,         /* index of file */

+    UInt32 *blockIndex,       /* index of solid block */

+    Byte **outBuffer,         /* pointer to pointer to output buffer (allocated with allocMain) */

+    size_t *outBufferSize,    /* buffer size for output buffer */

+    size_t *offset,           /* offset of stream for required file in *outBuffer */

+    size_t *outSizeProcessed, /* size of file in *outBuffer */

+    ISzAlloc *allocMain,

+    ISzAlloc *allocTemp);

+

+  If you need to decompress more than one file, you can send these values from previous call:

+    blockIndex, 

+    outBuffer, 

+    outBufferSize,

+  You can consider "outBuffer" as cache of solid block. If your archive is solid, 

+  it will increase decompression speed.

+

+  After decompressing you must free "outBuffer":

+  allocImp.Free(outBuffer);

+

+6) call SzArDbExFree(&db, allocImp.Free) to free allocated items in "db".

+

+

+

+

+Memory requirements for .7z decoding 

+------------------------------------

+

+Memory usage for Archive opening:

+  - Temporary pool:

+     - Memory for compressed .7z headers (if _LZMA_IN_CB is not defined)

+     - Memory for uncompressed .7z headers

+     - some other temporary blocks

+  - Main pool:

+     - Memory for database: 

+       Estimated size of one file structures in solid archive:

+         - Size (4 or 8 Bytes)

+         - CRC32 (4 bytes)

+         - Some file information (4 bytes)

+         - File Name (variable length) + pointer + allocation structures

+

+Memory usage for archive Decompressing:

+  - Temporary pool:

+     - Memory for compressed solid block (if _LZMA_IN_CB is not defined)

+     - Memory for LZMA decompressing structures

+  - Main pool:

+     - Memory for decompressed solid block

+  

+

+If _LZMA_IN_CB is defined, 7z Decoder will not allocate memory for 

+compressed blocks. Instead of this, you must allocate buffer with desired 

+size before calling 7z Decoder. Use 7zMain.c as example.

+

+

+

+EXIT codes

+-----------

+

+7z Decoder functions can return one of the following codes:

+

+#define SZ_OK (0)

+#define SZE_DATA_ERROR (1)

+#define SZE_OUTOFMEMORY (2)

+#define SZE_CRC_ERROR (3)

+

+#define SZE_NOTIMPL (4)

+#define SZE_FAIL (5)

+

+#define SZE_ARCHIVE_ERROR (6)

+

+

+

+LZMA Defines

+------------

+

+_LZMA_IN_CB       - Use special callback mode for input stream to reduce memory requirements

+

+_SZ_FILE_SIZE_64  - define it if you need support for files larger than 4 GB

+_SZ_NO_INT_64     - define it if your compiler doesn't support long long int

+

+_LZMA_PROB32      - it can increase LZMA decompressing speed on some 32-bit CPUs.

+

+_SZ_ONE_DIRECTORY - define it if you want to locate all source files to one directory

+_SZ_ALLOC_DEBUG   - define it if you want to debug alloc/free operations to stderr.

+      GNU LESSER GENERAL PUBLIC LICENSE

+           Version 2.1, February 1999

+

+ Copyright (C) 1991, 1999 Free Software Foundation, Inc.

+     59 Temple Place, Suite 330, Boston, MA  02111-1307  USA

+ Everyone is permitted to copy and distribute verbatim copies

+ of this license document, but changing it is not allowed.

+

+[This is the first released version of the Lesser GPL.  It also counts

+ as the successor of the GNU Library Public License, version 2, hence

+ the version number 2.1.]

+

+          Preamble

+

+  The licenses for most software are designed to take away your

+freedom to share and change it.  By contrast, the GNU General Public

+Licenses are intended to guarantee your freedom to share and change

+free software--to make sure the software is free for all its users.

+

+  This license, the Lesser General Public License, applies to some

+specially designated software packages--typically libraries--of the

+Free Software Foundation and other authors who decide to use it.  You

+can use it too, but we suggest you first think carefully about whether

+this license or the ordinary General Public License is the better

+strategy to use in any particular case, based on the explanations below.

+

+  When we speak of free software, we are referring to freedom of use,

+not price.  Our General Public Licenses are designed to make sure that

+you have the freedom to distribute copies of free software (and charge

+for this service if you wish); that you receive source code or can get

+it if you want it; that you can change the software and use pieces of

+it in new free programs; and that you are informed that you can do

+these things.

+

+  To protect your rights, we need to make restrictions that forbid

+distributors to deny you these rights or to ask you to surrender these

+rights.  These restrictions translate to certain responsibilities for

+you if you distribute copies of the library or if you modify it.

+

+  For example, if you distribute copies of the library, whether gratis

+or for a fee, you must give the recipients all the rights that we gave

+you.  You must make sure that they, too, receive or can get the source

+code.  If you link other code with the library, you must provide

+complete object files to the recipients, so that they can relink them

+with the library after making changes to the library and recompiling

+it.  And you must show them these terms so they know their rights.

+

+  We protect your rights with a two-step method: (1) we copyright the

+library, and (2) we offer you this license, which gives you legal

+permission to copy, distribute and/or modify the library.

+

+  To protect each distributor, we want to make it very clear that

+there is no warranty for the free library.  Also, if the library is

+modified by someone else and passed on, the recipients should know

+that what they have is not the original version, so that the original

+author's reputation will not be affected by problems that might be

+introduced by others.

+

+  Finally, software patents pose a constant threat to the existence of

+any free program.  We wish to make sure that a company cannot

+effectively restrict the users of a free program by obtaining a

+restrictive license from a patent holder.  Therefore, we insist that

+any patent license obtained for a version of the library must be

+consistent with the full freedom of use specified in this license.

+

+  Most GNU software, including some libraries, is covered by the

+ordinary GNU General Public License.  This license, the GNU Lesser

+General Public License, applies to certain designated libraries, and

+is quite different from the ordinary General Public License.  We use

+this license for certain libraries in order to permit linking those

+libraries into non-free programs.

+

+  When a program is linked with a library, whether statically or using

+a shared library, the combination of the two is legally speaking a

+combined work, a derivative of the original library.  The ordinary

+General Public License therefore permits such linking only if the

+entire combination fits its criteria of freedom.  The Lesser General

+Public License permits more lax criteria for linking other code with

+the library.

+

+  We call this license the "Lesser" General Public License because it

+does Less to protect the user's freedom than the ordinary General

+Public License.  It also provides other free software developers Less

+of an advantage over competing non-free programs.  These disadvantages

+are the reason we use the ordinary General Public License for many

+libraries.  However, the Lesser license provides advantages in certain

+special circumstances.

+

+  For example, on rare occasions, there may be a special need to

+encourage the widest possible use of a certain library, so that it becomes

+a de-facto standard.  To achieve this, non-free programs must be

+allowed to use the library.  A more frequent case is that a free

+library does the same job as widely used non-free libraries.  In this

+case, there is little to gain by limiting the free library to free

+software only, so we use the Lesser General Public License.

+

+  In other cases, permission to use a particular library in non-free

+programs enables a greater number of people to use a large body of

+free software.  For example, permission to use the GNU C Library in

+non-free programs enables many more people to use the whole GNU

+operating system, as well as its variant, the GNU/Linux operating

+system.

+

+  Although the Lesser General Public License is Less protective of the

+users' freedom, it does ensure that the user of a program that is

+linked with the Library has the freedom and the wherewithal to run

+that program using a modified version of the Library.

+

+  The precise terms and conditions for copying, distribution and

+modification follow.  Pay close attention to the difference between a

+"work based on the library" and a "work that uses the library".  The

+former contains code derived from the library, whereas the latter must

+be combined with the library in order to run.

+

+      GNU LESSER GENERAL PUBLIC LICENSE

+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION

+

+  0. This License Agreement applies to any software library or other

+program which contains a notice placed by the copyright holder or

+other authorized party saying it may be distributed under the terms of

+this Lesser General Public License (also called "this License").

+Each licensee is addressed as "you".

+

+  A "library" means a collection of software functions and/or data

+prepared so as to be conveniently linked with application programs

+(which use some of those functions and data) to form executables.

+

+  The "Library", below, refers to any such software library or work

+which has been distributed under these terms.  A "work based on the

+Library" means either the Library or any derivative work under

+copyright law: that is to say, a work containing the Library or a

+portion of it, either verbatim or with modifications and/or translated

+straightforwardly into another language.  (Hereinafter, translation is

+included without limitation in the term "modification".)

+

+  "Source code" for a work means the preferred form of the work for

+making modifications to it.  For a library, complete source code means

+all the source code for all modules it contains, plus any associated

+interface definition files, plus the scripts used to control compilation

+and installation of the library.

+

+  Activities other than copying, distribution and modification are not

+covered by this License; they are outside its scope.  The act of

+running a program using the Library is not restricted, and output from

+such a program is covered only if its contents constitute a work based

+on the Library (independent of the use of the Library in a tool for

+writing it).  Whether that is true depends on what the Library does

+and what the program that uses the Library does.

+  

+  1. You may copy and distribute verbatim copies of the Library's

+complete source code as you receive it, in any medium, provided that

+you conspicuously and appropriately publish on each copy an

+appropriate copyright notice and disclaimer of warranty; keep intact

+all the notices that refer to this License and to the absence of any

+warranty; and distribute a copy of this License along with the

+Library.

+

+  You may charge a fee for the physical act of transferring a copy,

+and you may at your option offer warranty protection in exchange for a

+fee.

+

+  2. You may modify your copy or copies of the Library or any portion

+of it, thus forming a work based on the Library, and copy and

+distribute such modifications or work under the terms of Section 1

+above, provided that you also meet all of these conditions:

+

+    a) The modified work must itself be a software library.

+

+    b) You must cause the files modified to carry prominent notices

+    stating that you changed the files and the date of any change.

+

+    c) You must cause the whole of the work to be licensed at no

+    charge to all third parties under the terms of this License.

+

+    d) If a facility in the modified Library refers to a function or a

+    table of data to be supplied by an application program that uses

+    the facility, other than as an argument passed when the facility

+    is invoked, then you must make a good faith effort to ensure that,

+    in the event an application does not supply such function or

+    table, the facility still operates, and performs whatever part of

+    its purpose remains meaningful.

+

+    (For example, a function in a library to compute square roots has

+    a purpose that is entirely well-defined independent of the

+    application.  Therefore, Subsection 2d requires that any

+    application-supplied function or table used by this function must

+    be optional: if the application does not supply it, the square

+    root function must still compute square roots.)

+

+These requirements apply to the modified work as a whole.  If

+identifiable sections of that work are not derived from the Library,

+and can be reasonably considered independent and separate works in

+themselves, then this License, and its terms, do not apply to those

+sections when you distribute them as separate works.  But when you

+distribute the same sections as part of a whole which is a work based

+on the Library, the distribution of the whole must be on the terms of

+this License, whose permissions for other licensees extend to the

+entire whole, and thus to each and every part regardless of who wrote

+it.

+

+Thus, it is not the intent of this section to claim rights or contest

+your rights to work written entirely by you; rather, the intent is to

+exercise the right to control the distribution of derivative or

+collective works based on the Library.

+

+In addition, mere aggregation of another work not based on the Library

+with the Library (or with a work based on the Library) on a volume of

+a storage or distribution medium does not bring the other work under

+the scope of this License.

+

+  3. You may opt to apply the terms of the ordinary GNU General Public

+License instead of this License to a given copy of the Library.  To do

+this, you must alter all the notices that refer to this License, so

+that they refer to the ordinary GNU General Public License, version 2,

+instead of to this License.  (If a newer version than version 2 of the

+ordinary GNU General Public License has appeared, then you can specify

+that version instead if you wish.)  Do not make any other change in

+these notices.

+

+  Once this change is made in a given copy, it is irreversible for

+that copy, so the ordinary GNU General Public License applies to all

+subsequent copies and derivative works made from that copy.

+

+  This option is useful when you wish to copy part of the code of

+the Library into a program that is not a library.

+

+  4. You may copy and distribute the Library (or a portion or

+derivative of it, under Section 2) in object code or executable form

+under the terms of Sections 1 and 2 above provided that you accompany

+it with the complete corresponding machine-readable source code, which

+must be distributed under the terms of Sections 1 and 2 above on a

+medium customarily used for software interchange.

+

+  If distribution of object code is made by offering access to copy

+from a designated place, then offering equivalent access to copy the

+source code from the same place satisfies the requirement to

+distribute the source code, even though third parties are not

+compelled to copy the source along with the object code.

+

+  5. A program that contains no derivative of any portion of the

+Library, but is designed to work with the Library by being compiled or

+linked with it, is called a "work that uses the Library".  Such a

+work, in isolation, is not a derivative work of the Library, and

+therefore falls outside the scope of this License.

+

+  However, linking a "work that uses the Library" with the Library

+creates an executable that is a derivative of the Library (because it

+contains portions of the Library), rather than a "work that uses the

+library".  The executable is therefore covered by this License.

+Section 6 states terms for distribution of such executables.

+

+  When a "work that uses the Library" uses material from a header file

+that is part of the Library, the object code for the work may be a

+derivative work of the Library even though the source code is not.

+Whether this is true is especially significant if the work can be

+linked without the Library, or if the work is itself a library.  The

+threshold for this to be true is not precisely defined by law.

+

+  If such an object file uses only numerical parameters, data

+structure layouts and accessors, and small macros and small inline

+functions (ten lines or less in length), then the use of the object

+file is unrestricted, regardless of whether it is legally a derivative

+work.  (Executables containing this object code plus portions of the

+Library will still fall under Section 6.)

+

+  Otherwise, if the work is a derivative of the Library, you may

+distribute the object code for the work under the terms of Section 6.

+Any executables containing that work also fall under Section 6,

+whether or not they are linked directly with the Library itself.

+

+  6. As an exception to the Sections above, you may also combine or

+link a "work that uses the Library" with the Library to produce a

+work containing portions of the Library, and distribute that work

+under terms of your choice, provided that the terms permit

+modification of the work for the customer's own use and reverse

+engineering for debugging such modifications.

+

+  You must give prominent notice with each copy of the work that the

+Library is used in it and that the Library and its use are covered by

+this License.  You must supply a copy of this License.  If the work

+during execution displays copyright notices, you must include the

+copyright notice for the Library among them, as well as a reference

+directing the user to the copy of this License.  Also, you must do one

+of these things:

+

+    a) Accompany the work with the complete corresponding

+    machine-readable source code for the Library including whatever

+    changes were used in the work (which must be distributed under

+    Sections 1 and 2 above); and, if the work is an executable linked

+    with the Library, with the complete machine-readable "work that

+    uses the Library", as object code and/or source code, so that the

+    user can modify the Library and then relink to produce a modified

+    executable containing the modified Library.  (It is understood

+    that the user who changes the contents of definitions files in the

+    Library will not necessarily be able to recompile the application

+    to use the modified definitions.)

+

+    b) Use a suitable shared library mechanism for linking with the

+    Library.  A suitable mechanism is one that (1) uses at run time a

+    copy of the library already present on the user's computer system,

+    rather than copying library functions into the executable, and (2)

+    will operate properly with a modified version of the library, if

+    the user installs one, as long as the modified version is

+    interface-compatible with the version that the work was made with.

+

+    c) Accompany the work with a written offer, valid for at

+    least three years, to give the same user the materials

+    specified in Subsection 6a, above, for a charge no more

+    than the cost of performing this distribution.

+

+    d) If distribution of the work is made by offering access to copy

+    from a designated place, offer equivalent access to copy the above

+    specified materials from the same place.

+

+    e) Verify that the user has already received a copy of these

+    materials or that you have already sent this user a copy.

+

+  For an executable, the required form of the "work that uses the

+Library" must include any data and utility programs needed for

+reproducing the executable from it.  However, as a special exception,

+the materials to be distributed need not include anything that is

+normally distributed (in either source or binary form) with the major

+components (compiler, kernel, and so on) of the operating system on

+which the executable runs, unless that component itself accompanies

+the executable.

+

+  It may happen that this requirement contradicts the license

+restrictions of other proprietary libraries that do not normally

+accompany the operating system.  Such a contradiction means you cannot

+use both them and the Library together in an executable that you

+distribute.

+

+  7. You may place library facilities that are a work based on the

+Library side-by-side in a single library together with other library

+facilities not covered by this License, and distribute such a combined

+library, provided that the separate distribution of the work based on

+the Library and of the other library facilities is otherwise

+permitted, and provided that you do these two things:

+

+    a) Accompany the combined library with a copy of the same work

+    based on the Library, uncombined with any other library

+    facilities.  This must be distributed under the terms of the

+    Sections above.

+

+    b) Give prominent notice with the combined library of the fact

+    that part of it is a work based on the Library, and explaining

+    where to find the accompanying uncombined form of the same work.

+

+  8. You may not copy, modify, sublicense, link with, or distribute

+the Library except as expressly provided under this License.  Any

+attempt otherwise to copy, modify, sublicense, link with, or

+distribute the Library is void, and will automatically terminate your

+rights under this License.  However, parties who have received copies,

+or rights, from you under this License will not have their licenses

+terminated so long as such parties remain in full compliance.

+

+  9. You are not required to accept this License, since you have not

+signed it.  However, nothing else grants you permission to modify or

+distribute the Library or its derivative works.  These actions are

+prohibited by law if you do not accept this License.  Therefore, by

+modifying or distributing the Library (or any work based on the

+Library), you indicate your acceptance of this License to do so, and

+all its terms and conditions for copying, distributing or modifying

+the Library or works based on it.

+

+  10. Each time you redistribute the Library (or any work based on the

+Library), the recipient automatically receives a license from the

+original licensor to copy, distribute, link with or modify the Library

+subject to these terms and conditions.  You may not impose any further

+restrictions on the recipients' exercise of the rights granted herein.

+You are not responsible for enforcing compliance by third parties with

+this License.

+  11. If, as a consequence of a court judgment or allegation of patent

+infringement or for any other reason (not limited to patent issues),

+conditions are imposed on you (whether by court order, agreement or

+otherwise) that contradict the conditions of this License, they do not

+excuse you from the conditions of this License.  If you cannot

+distribute so as to satisfy simultaneously your obligations under this

+License and any other pertinent obligations, then as a consequence you

+may not distribute the Library at all.  For example, if a patent

+license would not permit royalty-free redistribution of the Library by

+all those who receive copies directly or indirectly through you, then

+the only way you could satisfy both it and this License would be to

+refrain entirely from distribution of the Library.

+

+If any portion of this section is held invalid or unenforceable under any

+particular circumstance, the balance of the section is intended to apply,

+and the section as a whole is intended to apply in other circumstances.

+

+It is not the purpose of this section to induce you to infringe any

+patents or other property right claims or to contest validity of any

+such claims; this section has the sole purpose of protecting the

+integrity of the free software distribution system which is

+implemented by public license practices.  Many people have made

+generous contributions to the wide range of software distributed

+through that system in reliance on consistent application of that

+system; it is up to the author/donor to decide if he or she is willing

+to distribute software through any other system and a licensee cannot

+impose that choice.

+

+This section is intended to make thoroughly clear what is believed to

+be a consequence of the rest of this License.

+

+  12. If the distribution and/or use of the Library is restricted in

+certain countries either by patents or by copyrighted interfaces, the

+original copyright holder who places the Library under this License may add

+an explicit geographical distribution limitation excluding those countries,

+so that distribution is permitted only in or among countries not thus

+excluded.  In such case, this License incorporates the limitation as if

+written in the body of this License.

+

+  13. The Free Software Foundation may publish revised and/or new

+versions of the Lesser General Public License from time to time.

+Such new versions will be similar in spirit to the present version,

+but may differ in detail to address new problems or concerns.

+

+Each version is given a distinguishing version number.  If the Library

+specifies a version number of this License which applies to it and

+"any later version", you have the option of following the terms and

+conditions either of that version or of any later version published by

+the Free Software Foundation.  If the Library does not specify a

+license version number, you may choose any version ever published by

+the Free Software Foundation.

+

+  14. If you wish to incorporate parts of the Library into other free

+programs whose distribution conditions are incompatible with these,

+write to the author to ask for permission.  For software which is

+copyrighted by the Free Software Foundation, write to the Free

+Software Foundation; we sometimes make exceptions for this.  Our

+ordinary General Public License).

+

+  To apply these terms, attach the following notices to the library.  It is

+safest to attach them to the start of each source file to most effectively

+convey the exclusion of warranty; and each file should have at least the

+"copyright" line and a pointer to where the full notice is found.

+LZMA is default and general compression method of 7z format

+in 7-Zip compression program (www.7-zip.org). LZMA provides high 

+compression ratio and very fast decompression.

+

+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.

+LZMA SDK Contents

+-----------------

+

+LZMA SDK includes:

+

+  - C++ source code of LZMA compressing and decompressing

+  - ANSI-C compatible source code for LZMA decompressing

+  - C# source code for LZMA compressing and decompressing

+  - Java source code for LZMA compressing and decompressing

+But it is fully compatible with LZMA from 7-Zip.

+

+

+UNIX/Linux version 

+------------------

+To compile C++ version of file->file LZMA, go to directory

+C/7zip/Compress/LZMA_Alone 

+and type "make" or "make clean all" to recompile all.

+

+In some UNIX/Linux versions you must compile LZMA with static libraries.

+To compile with static libraries, change string in makefile

+LIB = -lm

+to string  

+LIB = -lm -static

+

+You can find ANSI-C LZMA decompressing code at folder 

+  C/7zip/Compress/LZMA_C

+7-Zip doesn't use that ANSI-C LZMA code and that code was developed 

+specially for this SDK. And files from LZMA_C do not need files from 

+other directories of SDK for compiling.

+

+7-Zip source code can be downloaded from 7-Zip's SourceForge page:

+

+  http://sourceforge.net/projects/sevenzip/

+

+

+LZMA features

+-------------

+  - Variable dictionary size (up to 1 GB)

+  - Estimated compressing speed: about 1 MB/s on 1 GHz CPU

+  - Estimated decompressing speed: 

+      - 8-12 MB/s on 1 GHz Intel Pentium 3 or AMD Athlon

+      - 500-1000 KB/s on 100 MHz ARM, MIPS, PowerPC or other simple RISC

+  - Small memory requirements for decompressing (8-32 KB + DictionarySize)

+  - Small code size for decompressing: 2-8 KB (depending from 

+    speed optimizations) 

+

+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 to speed of LZMA decompression:

+  1) 32*16 bit integer multiply

+  2) Misspredicted branches (penalty mostly depends from pipeline length)

+  3) 32-bit shift and arithmetic operations

+

+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 AMD Athlon 64 X2 CPU

+     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. Also you 

+     can change 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 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, ...).

+

+

+Using Filters

+-------------

+You can increase compression ratio for some data types, using

+special filters before compressing. For example, it's possible to 

+increase compression ratio on 5-10% for code for those CPU ISAs: 

+x86, IA-64, ARM, ARM-Thumb, PowerPC, SPARC.

+

+You can find C/C++ source code of such filters in folder "7zip/Compress/Branch"

+

+You can check 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=bc_arm -m1=lzma        

+

+With filter for big-endian ARM code (using additional Swap4 filter):

+  7z a a3.7z a.bin -m0=swap4 -m1=bc_arm -m2=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. Source code of these CALL filters is pretty simple

+(about 20 lines of C++), so you can convert it from C++ version yourself.

+

+For some ISAs (for example, for MIPS) it's impossible to get gain from such filter.

+

+

+  1     4   Dictionary size (little endian)

+  5     8   Uncompressed size (little endian). -1 means unknown size

+ 13         Compressed data

+

+

+ANSI-C LZMA Decoder

+~~~~~~~~~~~~~~~~~~~

+

+To compile ANSI-C LZMA Decoder you can use one of the following files sets:

+1) LzmaDecode.h + LzmaDecode.c + LzmaTest.c  (fastest version)

+2) LzmaDecode.h + LzmaDecodeSize.c + LzmaTest.c  (old size-optimized version)

+3) LzmaStateDecode.h + LzmaStateDecode.c + LzmaStateTest.c  (zlib-like interface)

+

+

+Memory requirements for LZMA decoding

+-------------------------------------

+

+LZMA decoder doesn't allocate memory itself, so you must 

+allocate memory and send it to LZMA.

+

+Stack usage of LZMA decoding function for local variables is not 

+larger than 200 bytes.

+

+How To decompress data

+----------------------

+

+LZMA Decoder (ANSI-C version) now supports 5 interfaces:

+1) Single-call Decompressing

+2) Single-call Decompressing with input stream callback

+3) Multi-call Decompressing with output buffer

+4) Multi-call Decompressing with input callback and output buffer

+5) Multi-call State Decompressing (zlib-like interface)

+

+Variant-5 is similar to Variant-4, but Variant-5 doesn't use callback functions.

+

+Decompressing steps

+-------------------

+

+1) read LZMA properties (5 bytes):

+   unsigned char properties[LZMA_PROPERTIES_SIZE];

+

+2) read uncompressed size (8 bytes, little-endian)

+

+3) Decode properties:

+

+  CLzmaDecoderState state;  /* it's 24-140 bytes structure, if int is 32-bit */

+

+  if (LzmaDecodeProperties(&state.Properties, properties, LZMA_PROPERTIES_SIZE) != LZMA_RESULT_OK)

+    return PrintError(rs, "Incorrect stream properties");

+

+4) Allocate memory block for internal Structures:

+

+  state.Probs = (CProb *)malloc(LzmaGetNumProbs(&state.Properties) * sizeof(CProb));

+  if (state.Probs == 0)

+    return PrintError(rs, kCantAllocateMessage);

+

+  LZMA decoder uses array of CProb variables as internal structure.

+  By default, CProb is unsigned_short. But you can define _LZMA_PROB32 to make 

+  it unsigned_int. It can increase speed on some 32-bit CPUs, but memory 

+  usage will be doubled in that case.

+

+

+5) Main Decompressing

+

+You must use one of the following interfaces:

+

+5.1 Single-call Decompressing

+-----------------------------

+When to use: RAM->RAM decompressing

+Compile files: LzmaDecode.h, LzmaDecode.c

+Compile defines: no defines

+Memory Requirements:

+  - Input buffer: compressed size

+  - Output buffer: uncompressed size

+  - LZMA Internal Structures (~16 KB for default settings) 

+

+Interface:

+  int res = LzmaDecode(&state, 

+      inStream, compressedSize, &inProcessed,

+      outStream, outSize, &outProcessed);

+

+

+5.2 Single-call Decompressing with input stream callback

+--------------------------------------------------------

+When to use: File->RAM or Flash->RAM decompressing.

+Compile files: LzmaDecode.h, LzmaDecode.c

+Compile defines: _LZMA_IN_CB

+Memory Requirements:

+  - Buffer for input stream: any size (for example, 16 KB)

+  - Output buffer: uncompressed size

+  - LZMA Internal Structures (~16 KB for default settings) 

+

+Interface:

+  typedef struct _CBuffer

+  {

+    ILzmaInCallback InCallback;

+    FILE *File;

+    unsigned char Buffer[kInBufferSize];

+  } CBuffer;

+

+  int LzmaReadCompressed(void *object, const unsigned char **buffer, SizeT *size)

+  {

+    CBuffer *bo = (CBuffer *)object;

+    *buffer = bo->Buffer;

+    *size = MyReadFile(bo->File, bo->Buffer, kInBufferSize);

+    return LZMA_RESULT_OK;

+  }

+

+  CBuffer g_InBuffer;

+

+  g_InBuffer.File = inFile;

+  g_InBuffer.InCallback.Read = LzmaReadCompressed;

+  int res = LzmaDecode(&state, 

+      &g_InBuffer.InCallback,

+      outStream, outSize, &outProcessed);

+

+

+5.3 Multi-call decompressing with output buffer

+-----------------------------------------------

+When to use: RAM->File decompressing 

+Compile files: LzmaDecode.h, LzmaDecode.c

+Compile defines: _LZMA_OUT_READ

+Memory Requirements:

+ - Input buffer: compressed size

+ - Buffer for output stream: any size (for example, 16 KB)

+ - LZMA Internal Structures (~16 KB for default settings) 

+ - LZMA dictionary (dictionary size is encoded in stream properties)

+ 

+Interface:

+

+  state.Dictionary = (unsigned char *)malloc(state.Properties.DictionarySize);

+

+  LzmaDecoderInit(&state);

+  do

+  {

+    LzmaDecode(&state,

+      inBuffer, inAvail, &inProcessed,

+      g_OutBuffer, outAvail, &outProcessed);

+    inAvail -= inProcessed;

+    inBuffer += inProcessed;

+  }

+  while you need more bytes

+

+  see LzmaTest.c for more details.

+

+

+5.4 Multi-call decompressing with input callback and output buffer

+------------------------------------------------------------------

+When to use: File->File decompressing 

+Compile files: LzmaDecode.h, LzmaDecode.c

+Compile defines: _LZMA_IN_CB, _LZMA_OUT_READ

+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 (~16 KB for default settings) 

+ - LZMA dictionary (dictionary size is encoded in stream properties)

+ 

+Interface:

+

+  state.Dictionary = (unsigned char *)malloc(state.Properties.DictionarySize);

+ 

+  LzmaDecoderInit(&state);

+  do

+  {

+    LzmaDecode(&state,

+      &bo.InCallback,

+      g_OutBuffer, outAvail, &outProcessed);

+  }

+  while you need more bytes

+

+  see LzmaTest.c for more details:

+

+

+5.5 Multi-call State Decompressing (zlib-like interface)

+------------------------------------------------------------------

+When to use: file->file decompressing 

+Compile files: LzmaStateDecode.h, LzmaStateDecode.c

+Compile defines:

+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 (~16 KB for default settings) 

+ - LZMA dictionary (dictionary size is encoded in stream properties)

+ 

+Interface:

+

+  state.Dictionary = (unsigned char *)malloc(state.Properties.DictionarySize);

+

+  

+  LzmaDecoderInit(&state);

+  do

+  {

+    res = LzmaDecode(&state,

+      inBuffer, inAvail, &inProcessed,

+      g_OutBuffer, outAvail, &outProcessed,

+      finishDecoding);

+    inAvail -= inProcessed;

+    inBuffer += inProcessed;

+  }

+  while you need more bytes

+

+  see LzmaStateTest.c for more details:

+

+

+6) Free all allocated blocks

+

+

+Note

+----

+LzmaDecodeSize.c is size-optimized version of LzmaDecode.c.

+But compiled code of LzmaDecodeSize.c can be larger than 

+compiled code of LzmaDecode.c. So it's better to use 

+LzmaDecode.c in most cases.

+

+

+EXIT codes

+-----------

+

+LZMA decoder can return one of the following codes:

+

+#define LZMA_RESULT_OK 0

+#define LZMA_RESULT_DATA_ERROR 1

+

+If you use callback function for input data and you return some 

+error code, LZMA Decoder also returns that code.

+

+

+

+LZMA Defines

+------------

+

+_LZMA_IN_CB    - Use callback for input data

+

+_LZMA_OUT_READ - Use read function for output data

+

+_LZMA_LOC_OPT  - Enable local speed optimizations inside code.

+                 _LZMA_LOC_OPT is only for LzmaDecodeSize.c (size-optimized version).

+                 _LZMA_LOC_OPT doesn't affect LzmaDecode.c (speed-optimized version)

+                 and LzmaStateDecode.c

+

+_LZMA_PROB32   - It can increase speed on some 32-bit CPUs, 

+                 but memory usage 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_SYSTEM_SIZE_T  - Define it if you want to use system's size_t.

+                       You can use it to enable 64-bit sizes supporting

+

+

+

+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.

+

+By default, LZMA Encoder contains all Match Finders.

+But for compressing it's enough to have just one of them.

+So for reducing size of compressing code you can define:

+  #define COMPRESS_MF_BT

+  #define COMPRESS_MF_BT4

+and it will use only bt4 match finder.

+unRAR license + GNU LGPL Notes

+------------------------------

+

+Please check main restriction from unRar license:

+

+   2. The unRAR sources may be used in any software to handle RAR

+      archives without limitations free of charge, but cannot be used

+      to re-create the RAR compression algorithm, which is proprietary.

+      Distribution of modified unRAR sources in separate form or as a

+      part of other software is permitted, provided that it is clearly

+      stated in the documentation and source comments that the code may

+      not be used to develop a RAR (WinRAR) compatible archiver.

+

+In brief it means:

+1) You can compile and use compiled files under GNU LGPL rules, since 

+   unRAR license almost has no restrictions for compiled files.

+   You can link these compiled files to LGPL programs.

+2) You can fix bugs in source code and use compiled fixed version.

+3) You can not use unRAR sources to re-create the RAR compression algorithm.

+

+

+7zip\Compress\Rar29\Original folder contains files that are modified

+versions of original unRAR source code files.

+

+

+License notes

+-------------

+

+You can support development of 7-Zip by registering.

+

+7-Zip is free software distributed under the GNU LGPL.

+If you need license with other conditions, write to

+http://www.7-zip.org/support.html

+

+---

+Also this package contains files from LZMA SDK

+you can download LZMA SDK from this page:

+http://www.7-zip.org/sdk.html

+read about addtional licenses for LZMA SDK in file

+DOC/lzma.txt

+

+

+How to compile

+--------------

+To compile sources you need Visual C++ 6.0.

+For compiling some files you also need 

+new Platform SDK from Microsoft' Site:

+http://www.microsoft.com/msdownload/platformsdk/sdkupdate/psdk-full.htm

+or

+http://www.microsoft.com/msdownload/platformsdk/sdkupdate/XPSP2FULLInstall.htm

+or

+http://www.microsoft.com/msdownload/platformsdk/sdkupdate/

+

+If you use MSVC6, specify SDK directories at top of directories lists:

+Tools / Options / Directories

+  - Include files

+  - Library files

+

+

+To compile 7-Zip for AMD64 and IA64 you need:

+  Windows Server 2003 SP1 Platform SDK from microsoft.com

+

+

+

+Compiling under Unix/Linux

+--------------------------

+Check this site for Posix/Linux version:

+http://sourceforge.net/projects/p7zip/

+

+

+Notes:

+------

+7-Zip consists of COM modules (DLL files).

+But 7-Zip doesn't use standard COM interfaces for creating objects.

+Look at

+7zip\UI\Client7z folder for example of using DLL files of 7-Zip. 

+Some DLL files can use other DLL files from 7-Zip.

+If you don't like it, you must use standalone version of DLL.

+To compile standalone version of DLL you must include all used parts

+to project and define some defs. 

+For example, 7zip\Bundles\Format7z is a standalone version  of 7z.dll 

+that works with 7z format. So you can use such DLL in your project 

+without additional DLL files.
