Introduction

libmspack is a library which provides compressors and decompressors, archivers and dearchivers for Microsoft compression formats.

Formats supported

The following file formats are supported:

  • SZDD files, which use LZSS compression
  • KWAJ files, which use LZSS, LZSS+Huffman or deflate compression
  • .HLP (MS Help) files, which use LZSS compression
  • .CAB (MS Cabinet) files, which use deflate, LZX or Quantum compression
  • .CHM (HTML Help) files, which use LZX compression
  • .LIT (MS EBook) files, which use LZX compression and DES encryption
  • .LZX (Exchange Offline Addressbook) files, which use LZX compression

To determine the capabilities of the library, and the binary compatibility version of any particular compressor or decompressor, use the mspack_version() function. The UNIX library interface version is defined as the highest-versioned library component.

Getting started

The macro MSPACK_SYS_SELFTEST() should be used to ensure the library can be used. In particular, it checks if the caller is using 32-bit file I/O when the library is compiled for 64-bit file I/O and vice versa.

If compiled normally, the library includes basic file I/O and memory management functionality using the standard C library. This can be customised and replaced entirely by creating a mspack_system structure.

A compressor or decompressor for the required format must be instantiated before it can be used. Each construction function takes one parameter, which is either a pointer to a custom mspack_system structure, or NULL to use the default. The instantiation returned, if not NULL, contains function pointers (methods) to work with the given file format.

For compression:

For decompression:

Once finished working with a format, each kind of compressor/decompressor has its own specific destructor:

Destroying a compressor or decompressor does not destroy any objects, structures or handles that have been created using that compressor or decompressor. Ensure that everything created or opened is destroyed or closed before compressor/decompressor is itself destroyed.

Error codes

All compressors and decompressors use the same set of error codes. Most methods return an error code directly. For methods which do not return error codes directly, the error code can be obtained with the last_error() method.

Multi-threading

libmspack methods are reentrant and multithreading-safe when each thread has its own compressor or decompressor.

You should not call multiple methods simultaneously on a single compressor or decompressor instance.

If this may happen, you can either use one compressor or decompressor per thread, or you can use your preferred lock, semaphore or mutex library to ensure no more than one method on a compressor/decompressor is called simultaneously. libmspack will not do this locking for you.

Example of incorrect behaviour:

  • thread 1 calls mspack_create_cab_decompressor()
  • thread 1 calls open()
  • thread 1 calls extract() for one file
  • thread 2 simultaneously calls extract() for another file

Correct behaviour:

Also correct behaviour:

  • thread 1 calls mspack_create_cab_decompressor()
  • thread 1 locks a mutex for with the decompressor before calling any methods on it, and unlocks the mutex after each method returns.
  • thread 1 can share the results of open() with thread 2, and both can call extract(), provided they both guard against simultaneous use of extract(), and any other methods, with the mutex

Detailed Description

A decompressor for .CAB (Microsoft Cabinet) files.

All fields are READ ONLY.

Field Documentation

int(* mscab_decompressor::append)(struct mscab_decompressor *self, struct mscabd_cabinet *cab, struct mscabd_cabinet *nextcab)

Appends one mscabd_cabinet to another, forming or extending a cabinet set.

This will attempt to append one cabinet to another such that (cab->nextcab == nextcab) && (nextcab->prevcab == cab) and any folders split between the two cabinets are merged.

The cabinets MUST be part of a cabinet set -- a cabinet set is a cabinet that spans more than one physical cabinet file on disk -- and must be appropriately matched.

It can be determined if a cabinet has further parts to load by examining the mscabd_cabinet::flags field:

If the cabinets do not match, an error code will be returned. Neither cabinet has been altered, and both should be closed seperately.

Files and folders in a cabinet set are a single entity. All cabinets in a set use the same file list, which is updated as cabinets in the set are added. All pointers to mscabd_folder and mscabd_file structures in either cabinet must be discarded and re-obtained after merging.

Parameters:
selfa self-referential pointer to the mscab_decompressor instance being called
cabthe cabinet which will be appended to, predecessor of nextcab
nextcabthe cabinet which will be appended, successor of cab
Returns:
an error code, or MSPACK_ERR_OK if successful
See also:
prepend(), open(), close()
void(* mscab_decompressor::close)(struct mscab_decompressor *self, struct mscabd_cabinet *cab)

Closes a previously opened cabinet or cabinet set.

This closes a cabinet, all cabinets associated with it via the mscabd_cabinet::next, mscabd_cabinet::prevcab and mscabd_cabinet::nextcab pointers, and all folders and files. All memory used by these entities is freed.

The cabinet pointer is now invalid and cannot be used again. All mscabd_folder and mscabd_file pointers from that cabinet or cabinet set are also now invalid, and cannot be used again.

If the cabinet pointer given was created using search(), it MUST be the cabinet pointer returned by search() and not one of the later cabinet pointers further along the mscabd_cabinet::next chain.

If extra cabinets have been added using append() or prepend(), these will all be freed, even if the cabinet pointer given is not the first cabinet in the set. Do NOT close() more than one cabinet in the set.

The mscabd_cabinet::filename is not freed by the library, as it is not allocated by the library. The caller should free this itself if necessary, before it is lost forever.

Parameters:
selfa self-referential pointer to the mscab_decompressor instance being called
cabthe cabinet to close
See also:
open(), search(), append(), prepend()
int(* mscab_decompressor::extract)(struct mscab_decompressor *self, struct mscabd_file *file, const char *filename)

Extracts a file from a cabinet or cabinet set.

This extracts a compressed file in a cabinet and writes it to the given filename.

The MS-DOS filename of the file, mscabd_file::filename, is NOT USED by extract(). The caller must examine this MS-DOS filename, copy and change it as necessary, create directories as necessary, and provide the correct filename as a parameter, which will be passed unchanged to the decompressor's mspack_system::open()

If the file belongs to a split folder in a multi-part cabinet set, and not enough parts of the cabinet set have been loaded and appended or prepended, an error will be returned immediately.

Parameters:
selfa self-referential pointer to the mscab_decompressor instance being called
filethe file to be decompressed
filenamethe filename of the file being written to
Returns:
an error code, or MSPACK_ERR_OK if successful
int(* mscab_decompressor::last_error)(struct mscab_decompressor *self)

Returns the error code set by the most recently called method.

This is useful for open() and search(), which do not return an error code directly.

Parameters:
selfa self-referential pointer to the mscab_decompressor instance being called
Returns:
the most recent error code
See also:
open(), search()
struct mscabd_cabinet*(* mscab_decompressor::open)(struct mscab_decompressor *self, const char *filename) [read]

Opens a cabinet file and reads its contents.

If the file opened is a valid cabinet file, all headers will be read and a mscabd_cabinet structure will be returned, with a full list of folders and files.

In the case of an error occuring, NULL is returned and the error code is available from last_error().

The filename pointer should be considered "in use" until close() is called on the cabinet.

Parameters:
selfa self-referential pointer to the mscab_decompressor instance being called
filenamethe filename of the cabinet file. This is passed directly to mspack_system::open().
Returns:
a pointer to a mscabd_cabinet structure, or NULL on failure
See also:
close(), search(), last_error()
int(* mscab_decompressor::prepend)(struct mscab_decompressor *self, struct mscabd_cabinet *cab, struct mscabd_cabinet *prevcab)

Prepends one mscabd_cabinet to another, forming or extending a cabinet set.

This will attempt to prepend one cabinet to another, such that (cab->prevcab == prevcab) && (prevcab->nextcab == cab). In all other respects, it is identical to append(). See append() for the full documentation.

Parameters:
selfa self-referential pointer to the mscab_decompressor instance being called
cabthe cabinet which will be prepended to, successor of prevcab
prevcabthe cabinet which will be prepended, predecessor of cab
Returns:
an error code, or MSPACK_ERR_OK if successful
See also:
append(), open(), close()
struct mscabd_cabinet*(* mscab_decompressor::search)(struct mscab_decompressor *self, const char *filename) [read]

Searches a regular file for embedded cabinets.

This opens a normal file with the given filename and will search the entire file for embedded cabinet files

If any cabinets are found, the equivalent of open() is called on each potential cabinet file at the offset it was found. All successfully open()ed cabinets are kept in a list.

The first cabinet found will be returned directly as the result of this method. Any further cabinets found will be chained in a list using the mscabd_cabinet::next field.

In the case of an error occuring anywhere other than the simulated open(), NULL is returned and the error code is available from last_error().

If no error occurs, but no cabinets can be found in the file, NULL is returned and last_error() returns MSPACK_ERR_OK.

The filename pointer should be considered in use until close() is called on the cabinet.

close() should only be called on the result of search(), not on any subsequent cabinets in the mscabd_cabinet::next chain.

Parameters:
selfa self-referential pointer to the mscab_decompressor instance being called
filenamethe filename of the file to search for cabinets. This is passed directly to mspack_system::open().
Returns:
a pointer to a mscabd_cabinet structure, or NULL
See also:
close(), open(), last_error()
int(* mscab_decompressor::set_param)(struct mscab_decompressor *self, int param, int value)

Sets a CAB decompression engine parameter.

The following parameters are defined:

  • MSCABD_PARAM_SEARCHBUF: How many bytes should be allocated as a buffer when using search()? The minimum value is 4. The default value is 32768.
  • MSCABD_PARAM_FIXMSZIP: If non-zero, extract() will ignore bad checksums and recover from decompression errors in MS-ZIP compressed folders. The default value is 0 (don't recover).
  • MSCABD_PARAM_DECOMPBUF: How many bytes should be used as an input bit buffer by decompressors? The minimum value is 4. The default value is 4096.
Parameters:
selfa self-referential pointer to the mscab_decompressor instance being called
paramthe parameter to set
valuethe value to set the parameter to
Returns:
MSPACK_ERR_OK if all is OK, or MSPACK_ERR_ARGS if there is a problem with either parameter or value.

Field Documentation

int(* mschm_compressor::generate)(struct mschm_compressor *self, struct mschmc_file file_list[], const char *output_file)

Generates a CHM help file.

The help file will contain up to two sections, an Uncompressed section and potentially an MSCompressed (LZX compressed) section.

While the contents listing of a CHM file is always in lexical order, the file list passed in will be taken as the correct order for files within the sections. It is in your interest to place similar files together for better compression.

There are two modes of generation, to use a temporary file or not to use one. See use_temporary_file() for the behaviour of generate() in these two different modes.

Parameters:
selfa self-referential pointer to the mschm_compressor instance being called
file_listan array of mschmc_file structures, terminated with an entry whose mschmc_file::section field is MSCHMC_ENDLIST. The order of the list is preserved within each section. The length of any mschmc_file::chm_filename string cannot exceed roughly 4096 bytes. Each source file must be able to supply as many bytes as given in the mschmc_file::length field.
output_filethe file to write the generated CHM helpfile to. This is passed directly to mspack_system::open()

Returns:

See also:
set_param(), generate()
int(* mschm_compressor::set_param)(struct mschm_compressor *self, int param, unsigned int value)

Sets a CHM compression engine parameter.

The following parameters are defined:

  • MSCHMC_PARAM_TIMESTAMP: Sets the "timestamp" of the CHM file generated. This is not a timestamp, see mschmd_header::timestamp for a description. If this timestamp is 0, generate() will use its own algorithm for making a unique ID, based on the lengths and names of files in the CHM itself. Defaults to 0, any value between 0 and (2^32)-1 is valid.
  • MSCHMC_PARAM_LANGUAGE: Sets the "language" of the CHM file generated. This is not the language used in the CHM file, but the language setting of the user who ran the HTMLHelp compiler. It defaults to 0x0409. The valid range is between 0x0000 and 0x7F7F.
  • MSCHMC_PARAM_LZXWINDOW: Sets the size of the LZX history window, which is also the interval at which the compressed data stream can be randomly accessed. The value is not a size in bytes, but a power of two. The default value is 16 (which makes the window 2^16 bytes, or 64 kilobytes), the valid range is from 15 (32 kilobytes) to 21 (2 megabytes).
  • MSCHMC_PARAM_DENSITY: Sets the "density" of quick reference entries stored at the end of directory listing chunk. Each chunk is 4096 bytes in size, and contains as many file entries as there is room for. At the other end of the chunk, a list of "quick reference" pointers is included. The offset of every 'N'th file entry is given a quick reference, where N = (2^density) + 1. The default density is 2. The smallest density is 0 (N=2), the maximum is 10 (N=1025). As each file entry requires at least 5 bytes, the maximum number of entries in a single chunk is roughly 800, so the maximum value 10 can be used to indicate there are no quickrefs at all.
  • MSCHMC_PARAM_INDEX: Sets whether or not to include quick lookup index chunk(s), in addition to normal directory listing chunks. A value of zero means no index chunks will be created, a non-zero value means index chunks will be created. The default is zero, "don't create an index".
Parameters:
selfa self-referential pointer to the mschm_compressor instance being called
paramthe parameter to set
valuethe value to set the parameter to
Returns:
MSPACK_ERR_OK if all is OK, or MSPACK_ERR_ARGS if there is a problem with either parameter or value.

generate()
int(* mschm_compressor::use_temporary_file)(struct mschm_compressor *self, int use_temp_file, const char *temp_file)

Specifies whether a temporary file is used during CHM generation.

The CHM file format includes data about the compressed section (such as its overall size) that is stored in the output CHM file prior to the compressed section itself. This unavoidably requires that the compressed section has to be generated, before these details can be set. There are several ways this can be handled. Firstly, the compressed section could be generated entirely in memory before writing any of the output CHM file. This approach is not used in libmspack, as the compressed section can exceed the addressable memory space on most architectures.

libmspack has two options, either to write these unknowable sections with blank data, generate the compressed section, then re-open the output file for update once the compressed section has been completed, or to write the compressed section to a temporary file, then write the entire output file at once, performing a simple file-to-file copy for the compressed section.

The simple solution of buffering the entire compressed section in memory can still be used, if desired. As the temporary file's filename is passed directly to mspack_system::open(), it is possible for a custom mspack_system implementation to hold this file in memory, without writing to a disk.

If a temporary file is set, generate() performs the following sequence of events: the temporary file is opened for writing, the compression algorithm writes to the temporary file, the temporary file is closed. Then the output file is opened for writing and the temporary file is re-opened for reading. The output file is written and the temporary file is read from. Both files are then closed. The temporary file itself is not deleted. If that is desired, the temporary file should be deleted after the completion of generate(), if it exists.

If a temporary file is set not to be used, generate() performs the following sequence of events: the output file is opened for writing, then it is written and closed. The output file is then re-opened for update, the appropriate sections are seek()ed to and re-written, then the output file is closed.

Parameters:
selfa self-referential pointer to the mschm_compressor instance being called
use_temp_filenon-zero if the temporary file should be used, zero if the temporary file should not be used.
temp_filea file to temporarily write compressed data to, before opening it for reading and copying the contents to the output file. This is passed directly to mspack_system::open().
Returns:
an error code, or MSPACK_ERR_OK if successful

Field Documentation

void(* mschm_decompressor::close)(struct mschm_decompressor *self, struct mschmd_header *chm)

Closes a previously opened CHM helpfile.

This closes a CHM helpfile, frees the mschmd_header and all mschmd_file structures associated with it (if any). This works on both helpfiles opened with open() and helpfiles opened with fast_open().

The CHM header pointer is now invalid and cannot be used again. All mschmd_file pointers referencing that CHM are also now invalid, and cannot be used again.

Parameters:
selfa self-referential pointer to the mschm_decompressor instance being called
chmthe CHM helpfile to close
See also:
open(), fast_open()
int(* mschm_decompressor::extract)(struct mschm_decompressor *self, struct mschmd_file *file, const char *filename)

Extracts a file from a CHM helpfile.

This extracts a file from a CHM helpfile and writes it to the given filename. The filename of the file, mscabd_file::filename, is not used by extract(), but can be used by the caller as a guide for constructing an appropriate filename.

This method works both with files found in the mschmd_header::files and mschmd_header::sysfiles list and mschmd_file structures generated on the fly by fast_find().

Parameters:
selfa self-referential pointer to the mschm_decompressor instance being called
filethe file to be decompressed
filenamethe filename of the file being written to
Returns:
an error code, or MSPACK_ERR_OK if successful
int(* mschm_decompressor::fast_find)(struct mschm_decompressor *self, struct mschmd_header *chm, const char *filename, struct mschmd_file *f_ptr, int f_size)

Finds file details quickly.

Instead of reading all CHM helpfile headers and building a list of files, fast_open() and fast_find() are intended for finding file details only when they are needed. The CHM file format includes an on-disk file index to allow this.

Given a case-sensitive filename, fast_find() will search the on-disk index for that file.

If the file was found, the caller-provided mschmd_file structure will be filled out like so:

  • section: the correct value for the found file
  • offset: the correct value for the found file
  • length: the correct value for the found file
  • all other structure elements: NULL or 0

If the file was not found, MSPACK_ERR_OK will still be returned as the result, but the caller-provided structure will be filled out like so:

  • section: NULL
  • offset: 0
  • length: 0
  • all other structure elements: NULL or 0

This method is intended to be used in conjunction with CHM helpfiles opened with fast_open(), but it also works with helpfiles opened using the regular open().

Parameters:
selfa self-referential pointer to the mschm_decompressor instance being called
chmthe CHM helpfile to search for the file
filenamethe filename of the file to search for
f_ptra pointer to a caller-provded mschmd_file structure
f_sizesizeof(struct mschmd_file)
Returns:
an error code, or MSPACK_ERR_OK if successful
See also:
open(), close(), fast_find(), extract()
struct mschmd_header*(* mschm_decompressor::fast_open)(struct mschm_decompressor *self, const char *filename) [read]

Opens a CHM helpfile quickly.

If the file opened is a valid CHM helpfile, only essential headers will be read. A mschmd_header structure will be still be returned, as with open(), but the mschmd_header::files field will be NULL. No files details will be automatically read. The fast_find() method must be used to obtain file details.

In the case of an error occuring, NULL is returned and the error code is available from last_error().

The filename pointer should be considered "in use" until close() is called on the CHM helpfile.

Parameters:
selfa self-referential pointer to the mschm_decompressor instance being called
filenamethe filename of the CHM helpfile. This is passed directly to mspack_system::open().
Returns:
a pointer to a mschmd_header structure, or NULL on failure
See also:
open(), close(), fast_find(), extract()
int(* mschm_decompressor::last_error)(struct mschm_decompressor *self)

Returns the error code set by the most recently called method.

This is useful for open() and fast_open(), which do not return an error code directly.

Parameters:
selfa self-referential pointer to the mschm_decompressor instance being called
Returns:
the most recent error code
See also:
open(), extract()
struct mschmd_header*(* mschm_decompressor::open)(struct mschm_decompressor *self, const char *filename) [read]

Opens a CHM helpfile and reads its contents.

If the file opened is a valid CHM helpfile, all headers will be read and a mschmd_header structure will be returned, with a full list of files.

In the case of an error occuring, NULL is returned and the error code is available from last_error().

The filename pointer should be considered "in use" until close() is called on the CHM helpfile.

Parameters:
selfa self-referential pointer to the mschm_decompressor instance being called
filenamethe filename of the CHM helpfile. This is passed directly to mspack_system::open().
Returns:
a pointer to a mschmd_header structure, or NULL on failure

Parameters:
selfa self-referential pointer to the mskwaj_compressor instance being called
inputthe name of the file to compressed. This is passed passed directly to mspack_system::open()
outputthe name of the file to write compressed data to. This is passed directly to mspack_system::open().
lengththe length of the uncompressed file, or -1 to indicate that this should be determined automatically by using mspack_system::seek() on the input file.
Returns:
an error code, or MSPACK_ERR_OK if successful
See also:
set_param()
int(* mskwaj_compressor::last_error)(struct mschm_decompressor *self)

int(* mskwaj_compressor::set_extra_data)(struct mskwaj_compressor *self, void *data, size_t bytes)

Sets arbitrary data that will be stored in the header of the output file, uncompressed.

It can be up to roughly 64 kilobytes, as the overall size of the header must not exceed 65535 bytes. The data can contain null bytes if desired.

If NULL is passed as the data pointer, or zero is passed as the length, no extra data is included in the header. This is the default.

Parameters:
selfa self-referential pointer to the mskwaj_compressor instance being called
dataa pointer to the data to be stored in the header
bytesthe length of the data in bytes
Returns:
MSPACK_ERR_OK if all is OK, or MSPACK_ERR_ARGS extra data is too long
int(* mskwaj_compressor::set_filename)(struct mskwaj_compressor *self, const char *filename)

Sets the original filename of the file before compression, which will be stored in the header of the output file.

The filename should be a null-terminated string, it must be an MS-DOS "8.3" type filename (up to 8 bytes for the filename, then optionally a "." and up to 3 bytes for a filename extension).

If NULL is passed as the filename, no filename is included in the header. This is the default.

Parameters:
selfa self-referential pointer to the mskwaj_compressor instance being called
filenamethe original filename to use
Returns:
MSPACK_ERR_OK if all is OK, or MSPACK_ERR_ARGS if the filename is too long
int(* mskwaj_compressor::set_param)(struct mskwaj_compressor *self, int param, unsigned int value)

Sets an KWAJ compression engine parameter.

The following parameters are defined:

  • MSKWAJC_PARAM_INCLUDE_LENGTH: a boolean; should the compressed output file should include the uncompressed length of the input file in the header? This adds 4 bytes to the size of the output file. A value of zero says "no", non-zero says "yes". The default is "no".
Parameters:
selfa self-referential pointer to the mskwaj_compressor instance being called
paramthe parameter to set
valuethe value to set the parameter to
Returns:
MSPACK_ERR_OK if all is OK, or MSPACK_ERR_ARGS if there is a problem with either parameter or value.

void(* mskwaj_decompressor::close)(struct mskwaj_decompressor *self, struct mskwajd_header *kwaj)

Closes a previously opened KWAJ file.

This closes a KWAJ file and frees the mskwajd_header associated with it. The KWAJ header pointer is now invalid and cannot be used again.

Parameters:
selfa self-referential pointer to the mskwaj_decompressor instance being called
kwajthe KWAJ file to close
See also:
open()
int(* mskwaj_decompressor::decompress)(struct mskwaj_decompressor *self, const char *input, const char *output)

Decompresses an KWAJ file to an output file in one step.

This opens an KWAJ file as input, reads the header, then decompresses the compressed data immediately to an output file, finally closing both the input and output file. It is more convenient to use than open() then extract() then close(), if you do not need to know the KWAJ output size or output filename.

Parameters:
selfa self-referential pointer to the mskwaj_decompressor instance being called
inputthe filename of the input KWAJ file. This is passed directly to mspack_system::open().
outputthe filename to write the decompressed data to. This is passed directly to mspack_system::open().
Returns:
an error code, or MSPACK_ERR_OK if successful
int(* mskwaj_decompressor::extract)(struct mskwaj_decompressor *self, struct mskwajd_header *kwaj, const char *filename)

Extracts the compressed data from a KWAJ file.

This decompresses the compressed KWAJ data stream and writes it to an output file.

Parameters:
selfa self-referential pointer to the mskwaj_decompressor instance being called
kwajthe KWAJ file to extract data from
filenamethe filename to write the decompressed data to. This is passed directly to mspack_system::open().
Returns:
an error code, or MSPACK_ERR_OK if successful
int(* mskwaj_decompressor::last_error)(struct mskwaj_decompressor *self)

Returns the error code set by the most recently called method.

This is useful for open() which does not return an error code directly.

Parameters:
selfa self-referential pointer to the mskwaj_decompressor instance being called
Returns:
the most recent error code
See also:
open(), search()
struct mskwajd_header*(* mskwaj_decompressor::open)(struct mskwaj_decompressor *self, const char *filename) [read]

Opens a KWAJ file and reads the header.

If the file opened is a valid KWAJ file, all headers will be read and a mskwajd_header structure will be returned.

In the case of an error occuring, NULL is returned and the error code is available from last_error().

The filename pointer should be considered "in use" until close() is called on the KWAJ file.

Parameters:
selfa self-referential pointer to the mskwaj_decompressor instance being called
filenamethe filename of the KWAJ compressed file. This is passed directly to mspack_system::open().
Returns:

Field Documentation

int(* msoab_decompressor::decompress)(struct msoab_decompressor *self, const char *input, const char *output)

Decompresses a full Offline Address Book file.

If the input file is a valid compressed Offline Address Book file, it will be read and the decompressed contents will be written to the output file.

Parameters:
selfa self-referential pointer to the msoab_decompressor instance being called
inputthe filename of the input file. This is passed directly to mspack_system::open().
outputthe filename of the output file. This is passed directly to mspack_system::open().
Returns:
an error code, or MSPACK_ERR_OK if successful
int(* msoab_decompressor::decompress_incremental)(struct msoab_decompressor *self, const char *input, const char *base, const char *output)

Decompresses an Offline Address Book with an incremental patch file.

This requires both a full UNCOMPRESSED Offline Address Book file to act as the "base", and a compressed incremental patch file as input. If the input file is valid, it will be decompressed with reference to the base file, and the decompressed contents will be written to the output file.

There is no way to tell what the right base file is for the given incremental patch, but if you get it wrong, this will usually result in incorrect data being decompressed, which will then fail a checksum test.

Parameters:
selfa self-referential pointer to the msoab_decompressor instance being called
inputthe filename of the input file. This is passed directly to mspack_system::open().
basethe filename of the base file to which the incremental patch shall be applied. This is passed directly to mspack_system::open().
outputthe filename of the output file. This is passed directly to mspack_system::open().
Returns:
an error code, or MSPACK_ERR_OK if successful

Detailed Description

A structure which abstracts file I/O and memory management.

The library always uses the mspack_system structure for interaction with the file system and to allocate, free and copy all memory. It also uses it to send literal messages to the library user.

When the library is compiled normally, passing NULL to a compressor or decompressor constructor will result in a default mspack_system being used, where all methods are implemented with the standard C library. However, all constructors support being given a custom created mspack_system structure, with the library user's own methods. This allows for more abstract interaction, such as reading and writing files directly to memory, or from a network socket or pipe.

Implementors of an mspack_system structure should read all documentation entries for every structure member, and write methods which conform to those standards.

Field Documentation

void*(* mspack_system::alloc)(struct mspack_system *self, size_t bytes)

Allocates memory.

Parameters:
selfa self-referential pointer to the mspack_system structure whose alloc() method is being called.
bytesthe number of bytes to allocate
Returns:
a pointer to the requested number of bytes, or NULL if not enough memory is available
See also:
free()
void(* mspack_system::close)(struct mspack_file *file)

Closes a previously opened file.

If any memory was allocated for this particular file handle, it should be freed at this time.

Parameters:
filethe file to close
See also:
open()
void(* mspack_system::copy)(void *src, void *dest, size_t bytes)

Copies from one region of memory to another.

The regions of memory are guaranteed not to overlap, are usually less than 256 bytes, and may not be aligned. Please note that the source parameter comes before the destination parameter, unlike the standard C function memcpy().

Parameters:
srcthe region of memory to copy from
destthe region of memory to copy to
bytesthe size of the memory region, in bytes
void(* mspack_system::free)(void *ptr)

Frees memory.

Parameters:
ptrthe memory to be freed.
See also:
alloc()
void(* mspack_system::message)(struct mspack_file *file, const char *format,...)

Used to send messages from the library to the user.

Occasionally, the library generates warnings or other messages in plain english to inform the human user. These are informational only and can be ignored if not wanted.

Parameters:
filemay be a file handle returned from open() if this message pertains to a specific open file, or NULL if not related to a specific file.
formata printf() style format string. It does NOT include a trailing newline.
See also:
open()
void* mspack_system::null_ptr

A null pointer to mark the end of mspack_system.

It must equal NULL.

Should the mspack_system structure extend in the future, this NULL will be seen, rather than have an invalid method pointer called.

struct mspack_file*(* mspack_system::open)(struct mspack_system *self, const char *filename, int mode) [read]

Opens a file for reading, writing, appending or updating.

Parameters:
selfa self-referential pointer to the mspack_system structure whose open() method is being called. If this pointer is required by close(), read(), write(), seek() or tell(), it should be stored in the result structure at this time.
filenamethe file to be opened. It is passed directly from the library caller without being modified, so it is up to the caller what this parameter actually represents.
modeone of MSPACK_SYS_OPEN_READ (open an existing file for reading), MSPACK_SYS_OPEN_WRITE (open a new file for writing), MSPACK_SYS_OPEN_UPDATE (open an existing file for reading/writing from the start of the file) or MSPACK_SYS_OPEN_APPEND (open an existing file for reading/writing from the end of the file)
Returns:
a pointer to a mspack_file structure. This structure officially contains no members, its true contents are up to the mspack_system implementor. It should contain whatever is needed for other mspack_system methods to operate. Returning the NULL pointer indicates an error condition.
See also:
close(), read(), write(), seek(), tell(), message()
int(* mspack_system::read)(struct mspack_file *file, void *buffer, int bytes)

Reads a given number of bytes from an open file.

Parameters:
filethe file to read from
bufferthe location where the read bytes should be stored
bytesthe number of bytes to read from the file.
Returns:
the number of bytes successfully read (this can be less than the number requested), zero to mark the end of file, or less than zero to indicate an error.
See also:
open(), write()
int(* mspack_system::seek)(struct mspack_file *file, off_t offset, int mode)

Seeks to a specific file offset within an open file.

Sometimes the library needs to know the length of a file. It does this by seeking to the end of the file with seek(file, 0, MSPACK_SYS_SEEK_END), then calling tell(). Implementations may want to make a special case for this.

Due to the potentially varying 32/64 bit datatype off_t on some architectures, the MSPACK_SYS_SELFTEST macro MUST be used before using the library. If not, the error caused by the library passing an inappropriate stackframe to seek() is subtle and hard to trace.

Parameters:
filethe file to be seeked
offsetan offset to seek, measured in bytes
modeone of MSPACK_SYS_SEEK_START (the offset should be measured from the start of the file), MSPACK_SYS_SEEK_CUR (the offset should be measured from the current file offset) or MSPACK_SYS_SEEK_END (the offset should be measured from the end of the file)
Returns:
zero for success, non-zero for an error
See also:
open(), tell()
off_t(* mspack_system::tell)(struct mspack_file *file)

Returns the current file position (in bytes) of the given file.

Parameters:
filethe file whose file position is wanted
Returns:
the current file position of the file
See also:
open(), seek()
int(* mspack_system::write)(struct mspack_file *file, void *buffer, int bytes)

Writes a given number of bytes to an open file.

Parameters:
filethe file to write to
bufferthe location where the written bytes should be read from
bytesthe number of bytes to write to the file.
Returns:
the number of bytes successfully written, this can be less than the number requested. Zero or less can indicate an error where no bytes at all could be written. All cases where less bytes were written than requested are considered by the library to be an error.

Field Documentation

int(* msszdd_compressor::compress)(struct msszdd_compressor *self, const char *input, const char *output, off_t length)

Reads an input file and creates a compressed output file in the SZDD compressed file format.

The SZDD compression format is quick but gives poor compression. It is possible for the compressed output file to be larger than the input file.

Conventionally, SZDD compressed files have the final character in their filename replaced with an underscore, to show they are compressed. The missing character is stored in the compressed file itself. This is due to the restricted filename conventions of MS-DOS, most operating systems, such as UNIX, simply append another file extension to the existing filename. As mspack does not deal with filenames, this is left up to you. If you wish to set the missing character stored in the file header, use set_param() with the MSSZDDC_PARAM_MISSINGCHAR parameter.

"Stream" compression (where the length of the input data is not known) is not possible. The length of the input data is stored in the header of the SZDD file and must therefore be known before any data is compressed. Due to technical limitations of the file format, the maximum size of uncompressed file that will be accepted is 2147483647 bytes.

Parameters:
selfa self-referential pointer to the msszdd_compressor instance being called
inputthe name of the file to compressed. This is passed passed directly to mspack_system::open()
outputthe name of the file to write compressed data to. This is passed directly to mspack_system::open().
lengththe length of the uncompressed file, or -1 to indicate that this should be determined automatically by using mspack_system::seek() on the input file.
Returns:
an error code, or MSPACK_ERR_OK if successful
See also:
set_param()
int(* msszdd_compressor::last_error)(struct mschm_decompressor *self)

Returns the error code set by the most recently called method.

Parameters:
selfa self-referential pointer to the msszdd_compressor instance being called
Returns:
the most recent error code
See also:
compress()
int(* msszdd_compressor::set_param)(struct msszdd_compressor *self, int param, unsigned int value)

Sets an SZDD compression engine parameter.

The following parameters are defined:

  • #MSSZDDC_PARAM_CHARACTER: the "missing character", the last character in the uncompressed file's filename, which is traditionally replaced with an underscore to show the file is compressed. Traditionally, this can only be a character that is a valid part of an MS-DOS, filename, but libmspack permits any character between 0x00 and 0xFF to be stored. 0x00 is the default, and it represents "no character stored".
Parameters:
selfa self-referential pointer to the msszdd_compressor instance being called
paramthe parameter to set
valuethe value to set the parameter to
Returns:
MSPACK_ERR_OK if all is OK, or MSPACK_ERR_ARGS if there is a problem with either parameter or value.

void(* msszdd_decompressor::close)(struct msszdd_decompressor *self, struct msszddd_header *szdd)

Closes a previously opened SZDD file.

This closes a SZDD file and frees the msszddd_header associated with it.

The SZDD header pointer is now invalid and cannot be used again.

Parameters:
selfa self-referential pointer to the msszdd_decompressor instance being called
szddthe SZDD file to close
See also:
open()
int(* msszdd_decompressor::decompress)(struct msszdd_decompressor *self, const char *input, const char *output)

Decompresses an SZDD file to an output file in one step.

This opens an SZDD file as input, reads the header, then decompresses the compressed data immediately to an output file, finally closing both the input and output file. It is more convenient to use than open() then extract() then close(), if you do not need to know the SZDD output size or missing character.

Parameters:
selfa self-referential pointer to the msszdd_decompressor instance being called
inputthe filename of the input SZDD file. This is passed directly to mspack_system::open().
outputthe filename to write the decompressed data to. This is passed directly to mspack_system::open().
Returns:
an error code, or MSPACK_ERR_OK if successful
int(* msszdd_decompressor::extract)(struct msszdd_decompressor *self, struct msszddd_header *szdd, const char *filename)

Extracts the compressed data from a SZDD file.

This decompresses the compressed SZDD data stream and writes it to an output file.

Parameters:
selfa self-referential pointer to the msszdd_decompressor instance being called
szddthe SZDD file to extract data from
filenamethe filename to write the decompressed data to. This is passed directly to mspack_system::open().
Returns:
an error code, or MSPACK_ERR_OK if successful
int(* msszdd_decompressor::last_error)(struct msszdd_decompressor *self)

Returns the error code set by the most recently called method.

This is useful for open() which does not return an error code directly.

Parameters:
selfa self-referential pointer to the msszdd_decompressor instance being called
Returns:
the most recent error code
See also:
open(), extract(), decompress()
struct msszddd_header*(* msszdd_decompressor::open)(struct msszdd_decompressor *self, const char *filename) [read]

Opens a SZDD file and reads the header.

If the file opened is a valid SZDD file, all headers will be read and a msszddd_header structure will be returned.

In the case of an error occuring, NULL is returned and the error code is available from last_error().

The filename pointer should be considered "in use" until close() is called on the SZDD file.

Parameters:
selfa self-referential pointer to the msszdd_decompressor instance being called
filenamethe filename of the SZDD compressed file. This is passed directly to mspack_system::open().
Returns:
a pointer to a msszddd_header structure, or NULL on failure

Field Documentation

int msszddd_header::format

The file format; either MSSZDD_FMT_NORMAL or MSSZDD_FMT_QBASIC.

off_t msszddd_header::length

The amount of data in the SZDD file once uncompressed.

char msszddd_header::missing_char

The last character in the filename, traditionally replaced with an underscore to show the file is compressed.

The null character is used to show that this character has not been stored (e.g. because the filename is not known). Generally, only characters that may appear in an MS-DOS filename (except ".") are valid.

The documentation for this struct was generated from the following file:
Generated by   doxygen 1.7.6.1
libmspack-0.4alpha/doc/szdd_kwaj_format.html0000644000175000017500000003624011571043220016234 00000000000000 COMPRESS.EXE file formats: SZDD and KWAJ

COMPRESS.EXE file formats: SZDD and KWAJ

This document describes the SZDD and KWAJ file formats which are implemented in the MS-DOS commands COMPRESS.EXE and EXPAND.EXE.

Both formats compress a single file to another single file, replacing the last character in the filename with an underscore or dollar character, e.g. README.TXT becomes README.TX_ or README.TX$.

SZDD file format

An SZDD file begins with this fixed header:

SZDD header format
OffsetLengthDescription
0x008"SZDD" signature: 0x53,0x5A,0x44,0x44,0x88,0xF0,0x27,0x33
0x081Compression mode: only "A" (0x41) is valid here
0x091The character missing from the end of the filename (0=unknown)
0x0A4The integer length of the file when unpacked

The header is immediately followed by the compressed data. The following pseudocode explains how to unpack this data; it's a form of the LZSS algorithm.

SZDD decompression pseudocode 
char window[4096];
int pos = 4096 - 16;
memset(window, 0x20, 4096); /* window initially full of spaces */
for (;;) {
    int control = GETBYTE();
    if (control == EOF) break; /* exit if no more to read */
    for (int cbit = 0x01; cbit & 0xFF; cbit <<= 1) {
        if (control & cbit) {
            /* literal */
            PUTBYTE(window[pos++] = GETBYTE());
        }
        else {
            /* match */
            int matchpos = GETBYTE();
            int matchlen = GETBYTE();
            matchpos |= (matchlen & 0xF0) << 4;
            matchlen = (matchlen & 0x0F) + 3;
            while (matchlen--) {
                PUTBYTE(window[pos++] = window[matchpos++]);
                pos &= 4095; matchpos &= 4095;
            }
        }
    }
}

There is also a variant SZDD format seen in the installation package for QBasic 4.5, so I call it the QBasic variant. It has a different header and the pos variable in the pseudocode above is set to 4096-18 instead of 4096-16.

QBasic SZDD variant header format
OffsetLengthDescription
0x008"SZ" signature: 0x53,0x5A,0x20,0x88,0xF0,0x27,0x33,0xD1
0x084The integer length of the file when unpacked

KWAJ file format

A KWAJ file begins with this fixed header:

KWAJ header format
OffsetLengthDescription
0x008"KWAJ" signature: 0x4B,0x57,0x41,0x4A,0x88,0xF0,0x27,0xD1
0x082compression method (0-4)
0x0A2file offset of compressed data
0x0C2header flags to mark header extensions

Compression methods

The "compression method" field indicates the type of data compression used:

  1. No compression
  2. No compression, data is XORed with byte 0xFF
  3. The same compression method as regular SZDD
  4. LZ + Huffman "Jeff Johnson" compression
  5. MS-ZIP

Header extensions

Header extensions immediately follow the header.

If you don't care about the header extensions, use the file offset to skip to the compressed data.

The header extensions appear in this order:

When header flags bit 0 is set
4 bytes: decompressed length of file
When header flags bit 1 is set
2 bytes: unknown purpose
When header flags bit 2 is set
2 bytes: length of data, followed by that many bytes of (unknown purpose) data
When header flags bit 3 is set
1-9 bytes: null-terminated string with max length 8: file name
When header flags bit 4 is set
1-4 bytes: null-terminated string with max length 3: file extension
When header flags bit 5 is set
2 bytes: length of data, followed by that many bytes of (arbitrary text) data

KWAJ compression method 3

Compression method 3 is unique to the KWAJ format. It's an LZ+Huffman algorithm created by Jeff Johnson.

Bits are always read from MSB to LSB, one byte at a time.

There are three parts:

  1. The data starts off with 6 nybbles; 4 bits each. Each nybble is between 0-3 and is the encoding type of the 5 huffman length lists to follow. The 6th nybble is just padding.
  2. Then follow 5 huffman code length lists.
  3. Then follows the compressed data, which is a mix of huffman symbols and raw bits.

Huffman code length lists

KWAJ uses 5 huffman trees. They always have the same number of symbols in them. They are, in order:

  1. 16 symbol tree (0-15) to store match run lengths (MATCHLEN)
  2. 16 symbol tree (0-15) to store match run lengths immediately following a short literal run (MATCHLEN2)
  3. 32 symbol tree (0-31) to store literal run lengths (LITLEN)
  4. 64 symbol tree (0-63) to store the upper 6 bits of match distances (OFFSET)
  5. 256 symbol tree (0-255) to store literals (LITERAL)

Canonical huffman codes are used, which means you simply need to know how many symbols in each huffman tree (given above), and how long each huffman symbol is

How the symbol lengths are encoded depends on the encoding type, as given by the 6 nybbles at the start of the compressed data.

Symbol lengths are read in ascending order, and the number of symbols to read is implied by which tree you're defining.

Huffman code length list, encoding type 0
All symbol have the same length, implied by the number of symbols in the tree:
  • 16 symbols -> all symbols are length 4
  • 32 symbols -> all symbols are length 5
  • 64 symbols -> all symbols are length 6
  • 256 symbols -> all symbols are length 8
You don't need to read anything.
Huffman code length list, encoding type 1
A run-length encoding is used:
  • read 4 bits for the first symbol length (0-15)
  • LOOP:
    • read 1 bit == 0 if symbol length is the same as the previous, OTHERWISE:
    • read 1 bit == 0 if symbol length is previous + 1, OTHERWISE:
    • read 4 bits for symbol length (0-15)
Huffman code length list, encoding type 2
Another run-length encoding is used:
  • read 4 bits for the first symbol length (0-15)
  • LOOP:
    • read 2 bits as selector (0-3):
      • selector == 3: read 4 bits for symbol length, OTHERWISE:
      • symbol length is previous symbol + (selector-1), i.e. -1, 0 or +1
Huffman code length list, encoding type 3
There is no compression. Read 4 bits per symbol (0-15).

Compressed data

At this point, the compressed data begins.

We have a 4096 byte ring buffer, initially filled with byte 0x20 (ASCII space). Unlike the SZDD format, the starting position in the buffer is irrelevant, as match positions are stored relative to the current position in the window, not as absolute positions in the window.

Pseudo-code:

 ring buffer position = 4096-17
 selected table = MATCHLEN
 LOOP:
     code = read huffman code using selected table (MATCHLEN or MATCHLEN2)
     if EOF reached, exit loop
     if code > 0, this is a match:
         match length = code + 2
         x = read huffman code using OFFSET table
         y = read 6 bits
         match offset = current ring buffer position - (x<<6 | y)
         copy match as output and into the ring buffer
         selected table = MATCHLEN
     if code == 0, this is a run of literals:
         x = read huffman code using LITLEN table
         if x != 31, selected table = MATCHLEN2
         read {x+1} literals using LITERAL huffman table, copy as output and into the ring buffer

MS-ZIP

 KWAJ type 4 compression is called MS-ZIP, because it is almost identical to the MS-ZIP compression found in Microsoft Cabinet files. Each 32768 bytes of data is compressed independently using Phil Katz's DEFLATE algorithm. However, the history window is shared between blocks, so they must be unpacked in order. The format of each block is as follows:
KWAJ MS-ZIP block format
OffsetLengthDescription
02Compressed length of this block (n). Stored in Intel byte order. Doesn't include these two bytes.
22"CK" in ASCII (0x43, 0x4B)
4n-2Data compressed in DEFLATE format
The final block will unpack to 1-32768 bytes. It will be followed by two zero bytes. libmspack-0.4alpha/doc/tab_a.png0000664000175000017500000000021412151103221013555 00000000000000PNG  IHDR$[SIDATx흻 @wɡ*MIFL :nN N&_ ɭɾ}ն8~Owv-A4Y)}IENDB`libmspack-0.4alpha/doc/tab_b.png0000664000175000017500000000026212151103221013561 00000000000000PNG  IHDR$[yIDATx ?|SVӈbB#P8O:əD>m{SI'z(!TBމy#WJDp|Å R] 6q]qD.&0=JD=@**IENDB`libmspack-0.4alpha/doc/tab_h.png0000664000175000017500000000030012151103221013560 00000000000000PNG  IHDR$[IDATx `FhY 26@cHw!ϗK1^HtOyGD׎ k9?i7zvPaJ})غwV`ai֍ZPC"P=IENDB`libmspack-0.4alpha/doc/tabs.css0000664000175000017500000000210712151103221013447 00000000000000.tabs, .tabs2, .tabs3 { background-image: url('tab_b.png'); width: 100%; z-index: 101; font-size: 13px; } .tabs2 { font-size: 10px; } .tabs3 { font-size: 9px; } .tablist { margin: 0; padding: 0; display: table; } .tablist li { float: left; display: table-cell; background-image: url('tab_b.png'); line-height: 36px; list-style: none; } .tablist a { display: block; padding: 0 20px; font-weight: bold; background-image:url('tab_s.png'); background-repeat:no-repeat; background-position:right; color: #283A5D; text-shadow: 0px 1px 1px rgba(255, 255, 255, 0.9); text-decoration: none; outline: none; } .tabs3 .tablist a { padding: 0 10px; } .tablist a:hover { background-image: url('tab_h.png'); background-repeat:repeat-x; color: #fff; text-shadow: 0px 1px 1px rgba(0, 0, 0, 1.0); text-decoration: none; } .tablist li.current a { background-image: url('tab_a.png'); background-repeat:repeat-x; color: #fff; text-shadow: 0px 1px 1px rgba(0, 0, 0, 1.0); } libmspack-0.4alpha/doc/tab_s.png0000664000175000017500000000027512151103221013606 00000000000000PNG  IHDR$[IDATx P@Kg"%(IE|%I7ilm" ӏCۓ\.dOZ̤Br/(#a6 8qaF-EtA4fl]JjJC%!<#īIENDB`libmspack-0.4alpha/m4/0000775000175000017500000000000012151103222011640 500000000000000libmspack-0.4alpha/m4/libtool.m40000644000175000017500000106043412151103153013477 00000000000000# libtool.m4 - Configure libtool for the host system. -*-Autoconf-*- # # Copyright (C) 1996, 1997, 1998, 1999, 2000, 2001, 2003, 2004, 2005, # 2006, 2007, 2008, 2009, 2010, 2011 Free Software # Foundation, Inc. # Written by Gordon Matzigkeit, 1996 # # This file is free software; the Free Software Foundation gives # unlimited permission to copy and/or distribute it, with or without # modifications, as long as this notice is preserved. m4_define([_LT_COPYING], [dnl # Copyright (C) 1996, 1997, 1998, 1999, 2000, 2001, 2003, 2004, 2005, # 2006, 2007, 2008, 2009, 2010, 2011 Free Software # Foundation, Inc. # Written by Gordon Matzigkeit, 1996 # # This file is part of GNU Libtool. # # GNU Libtool is free software; you can redistribute it and/or # modify it under the terms of the GNU General Public License as # published by the Free Software Foundation; either version 2 of # the License, or (at your option) any later version. # # As a special exception to the GNU General Public License, # if you distribute this file as part of a program or library that # is built using GNU Libtool, you may include this file under the # same distribution terms that you use for the rest of that program. # # GNU Libtool is distributed in the hope that it will be useful, # but WITHOUT ANY WARRANTY; without even the implied warranty of # MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

The UNIX library interface version is * defined as the highest-versioned library component. * * \section starting Getting started * * The macro MSPACK_SYS_SELFTEST() should be used to ensure the library can * be used. In particular, it checks if the caller is using 32-bit file I/O * when the library is compiled for 64-bit file I/O and vice versa. * * If compiled normally, the library includes basic file I/O and memory * management functionality using the standard C library. This can be * customised and replaced entirely by creating a mspack_system structure. * * A compressor or decompressor for the required format must be * instantiated before it can be used. Each construction function takes * one parameter, which is either a pointer to a custom mspack_system * structure, or NULL to use the default. The instantiation returned, if * not NULL, contains function pointers (methods) to work with the given * file format. * * For compression: * - mspack_create_cab_compressor() creates a mscab_compressor * - mspack_create_chm_compressor() creates a mschm_compressor * - mspack_create_lit_compressor() creates a mslit_compressor * - mspack_create_hlp_compressor() creates a mshlp_compressor * - mspack_create_szdd_compressor() creates a msszdd_compressor * - mspack_create_kwaj_compressor() creates a mskwaj_compressor * - mspack_create_oab_compressor() creates a msoab_compressor * * For decompression: * - mspack_create_cab_decompressor() creates a mscab_decompressor * - mspack_create_chm_decompressor() creates a mschm_decompressor * - mspack_create_lit_decompressor() creates a mslit_decompressor * - mspack_create_hlp_decompressor() creates a mshlp_decompressor * - mspack_create_szdd_decompressor() creates a msszdd_decompressor * - mspack_create_kwaj_decompressor() creates a mskwaj_decompressor * - mspack_create_oab_decompressor() creates a msoab_decompressor * * Once finished working with a format, each kind of * compressor/decompressor has its own specific destructor: * - mspack_destroy_cab_compressor() * - mspack_destroy_cab_decompressor() * - mspack_destroy_chm_compressor() * - mspack_destroy_chm_decompressor() * - mspack_destroy_lit_compressor() * - mspack_destroy_lit_decompressor() * - mspack_destroy_hlp_compressor() * - mspack_destroy_hlp_decompressor() * - mspack_destroy_szdd_compressor() * - mspack_destroy_szdd_decompressor() * - mspack_destroy_kwaj_compressor() * - mspack_destroy_kwaj_decompressor() * - mspack_destroy_oab_compressor() * - mspack_destroy_oab_decompressor() * * Destroying a compressor or decompressor does not destroy any objects, * structures or handles that have been created using that compressor or * decompressor. Ensure that everything created or opened is destroyed or * closed before compressor/decompressor is itself destroyed. * * \section errors Error codes * * All compressors and decompressors use the same set of error codes. Most * methods return an error code directly. For methods which do not * return error codes directly, the error code can be obtained with the * last_error() method. * * - #MSPACK_ERR_OK is used to indicate success. This error code is defined * as zero, all other code are non-zero. * - #MSPACK_ERR_ARGS indicates that a method was called with inappropriate * arguments. * - #MSPACK_ERR_OPEN indicates that mspack_system::open() failed. * - #MSPACK_ERR_READ indicates that mspack_system::read() failed. * - #MSPACK_ERR_WRITE indicates that mspack_system::write() failed. * - #MSPACK_ERR_SEEK indicates that mspack_system::seek() failed. * - #MSPACK_ERR_NOMEMORY indicates that mspack_system::alloc() failed. * - #MSPACK_ERR_SIGNATURE indicates that the file being read does not * have the correct "signature". It is probably not a valid file for * whatever format is being read. * - #MSPACK_ERR_DATAFORMAT indicates that the file being used or read * is corrupt. * - #MSPACK_ERR_CHECKSUM indicates that a data checksum has failed. * - #MSPACK_ERR_CRUNCH indicates an error occured during compression. * - #MSPACK_ERR_DECRUNCH indicates an error occured during decompression. * * \section threading Multi-threading * * libmspack methods are reentrant and multithreading-safe when each * thread has its own compressor or decompressor. * You should not call multiple methods simultaneously on a single * compressor or decompressor instance. * * If this may happen, you can either use one compressor or * decompressor per thread, or you can use your preferred lock, * semaphore or mutex library to ensure no more than one method on a * compressor/decompressor is called simultaneously. libmspack will * not do this locking for you. * * Example of incorrect behaviour: * - thread 1 calls mspack_create_cab_decompressor() * - thread 1 calls open() * - thread 1 calls extract() for one file * - thread 2 simultaneously calls extract() for another file * * Correct behaviour: * - thread 1 calls mspack_create_cab_decompressor() * - thread 2 calls mspack_create_cab_decompressor() * - thread 1 calls its own open() / extract() * - thread 2 simultaneously calls its own open() / extract() * * Also correct behaviour: * - thread 1 calls mspack_create_cab_decompressor() * - thread 1 locks a mutex for with the decompressor before * calling any methods on it, and unlocks the mutex after each * method returns. * - thread 1 can share the results of open() with thread 2, and both * can call extract(), provided they both guard against simultaneous * use of extract(), and any other methods, with the mutex */ #ifndef LIB_MSPACK_H #define LIB_MSPACK_H 1 #ifdef __cplusplus extern "C" { #endif #include #include /** * System self-test function, to ensure both library and calling program * can use one another. * * A result of MSPACK_ERR_OK means the library and caller are * compatible.

The CAB * specification is specifically designed to work like this, as it ensures * compression matches do not span the maximum decompressed block size * limit of 32kb. * * However, the compression algorithms used are stream oriented, with * specific hacks added to them to enforce the "individual 32kb blocks" * rule in CABs. In other file formats, they do not have this limitation. * * In order to make more generalised decompressors, libmspack's CAB * decompressor has moved from being block-oriented to more stream * oriented. This also makes decompression slightly faster. * * However, this leads to incompliance with the CAB specification. The * CAB controller can no longer ensure each block of input given to the * decompressors is matched with their output. The "decompressed size" of * each individual block is thrown away. * * Each CAB block is supposed to be seen as individually compressed. This * means each consecutive data block can have completely different * "uncompressed" sizes, ranging from 1 to 32768 bytes. However, in * reality, all data blocks in a folder decompress to exactly 32768 bytes, * excepting the final block. * * Given this situation, the decompression algorithms are designed to * realign their input bitstreams on 32768 output-byte boundaries, and * various other special cases have been made. libmspack will not * correctly decompress LZX or Quantum compressed folders where the blocks * do not follow this "32768 bytes until last block" pattern. It could be * implemented if needed, but hopefully this is not necessary -- it has * not been seen in over 3Gb of CAB archives. */ /* prototypes */ static struct mscabd_cabinet * cabd_open( struct mscab_decompressor *base, const char *filename);

It states that the 1MB * window = 40 slots and the 2MB window = 42 slots. In the implementation, * 1MB = 42 slots, 2MB = 50 slots. The actual calculation is 'find the * first slot whose position base is equal to or more than the required * window size'. This would explain why other tables in the document refer * to 50 slots rather than 42. * * The constant NUM_PRIMARY_LENGTHS used in the decompression pseudocode * is not defined in the specification. * * The LZX document does not state the uncompressed block has an * uncompressed length field. Where does this length field come from, so * we can know how large the block is? The implementation has it as the 24 * bits following after the 3 blocktype bits, before the alignment * padding. * * The LZX document states that aligned offset blocks have their aligned * offset huffman tree AFTER the main and length trees. The implementation * suggests that the aligned offset tree is BEFORE the main and length * trees. * * The LZX document decoding algorithm states that, in an aligned offset * block, if an extra_bits value is 1, 2 or 3, then that number of bits * should be read and the result added to the match offset. This is * correct for 1 and 2, but not 3, where just a huffman symbol (using the * aligned tree) should be read. * * Regarding the E8 preprocessing, the LZX document states 'No translation * may be performed on the last 6 bytes of the input block'. This is * correct. However, the pseudocode provided checks for the *E8 leader* * up to the last 6 bytes. If the leader appears between -10 and -7 bytes * from the end, this would cause the next four bytes to be modified, at * least one of which would be in the last 6 bytes, which is not allowed * according to the spec. * * The specification states that the huffman trees must always contain at * least one element. However, many CAB files contain blocks where the * length tree is completely empty (because there are no matches), and * this is expected to succeed. * * The errors in LZX documentation appear have been corrected in the * new documentation for the LZX DELTA format. * * http://msdn.microsoft.com/en-us/library/cc483133.aspx * * However, this is a different format, an extension of regular LZX. * I have noticed the following differences, there may be more: * * The maximum window size has increased from 2MB to 32MB. This also * increases the maximum number of position slots, etc. * * If the match length is 257 (the maximum possible), this signals * a further length decoding step, that allows for matches up to * 33024 bytes long. * * The format now allows for "reference data", supplied by the caller. * If match offsets go further back than the number of bytes * decompressed so far, that is them accessing the reference data. */ /* import bit-reading macros and code */ #define BITS_TYPE struct lzxd_stream #define BITS_VAR lzx #define BITS_ORDER_MSB #define READ_BYTES do { \ unsigned char b0, b1; \ READ_IF_NEEDED; b0 = *i_ptr++; \ READ_IF_NEEDED; b1 = *i_ptr++; \ INJECT_BITS((b1 << 8) | b0, 16); \ } while (0) #include /* import huffman-reading macros and code */ #define TABLEBITS(tbl) LZX_##tbl##_TABLEBITS #define MAXSYMBOLS(tbl) LZX_##tbl##_MAXSYMBOLS #define HUFF_TABLE(tbl,idx) lzx->tbl##_table[idx] #define HUFF_LEN(tbl,idx) lzx->tbl##_len[idx] #define HUFF_ERROR return lzx->error = MSPACK_ERR_DECRUNCH #include /* BUILD_TABLE(tbl) builds a huffman lookup table from code lengths */ #define BUILD_TABLE(tbl) \ if (make_decode_table(MAXSYMBOLS(tbl), TABLEBITS(tbl), \ &HUFF_LEN(tbl,0), &HUFF_TABLE(tbl,0))) \ { \ D(("failed to build %s table", #tbl)) \ return lzx->error = MSPACK_ERR_DECRUNCH; \ } #define BUILD_TABLE_MAYBE_EMPTY(tbl) do { \ lzx->tbl##_empty = 0; \ if (make_decode_table(MAXSYMBOLS(tbl), TABLEBITS(tbl), \ &HUFF_LEN(tbl,0), &HUFF_TABLE(tbl,0))) \ { \ for (i = 0; i < MAXSYMBOLS(tbl); i++) { \ if (HUFF_LEN(tbl, i) > 0) { \ D(("failed to build %s table", #tbl)) \ return lzx->error = MSPACK_ERR_DECRUNCH; \ } \ } \ /* empty tree - allow it, but don't decode symbols with it */ \ lzx->tbl##_empty = 1; \ } \ } while (0) /* READ_LENGTHS(tablename, first, last) reads in code lengths for symbols * first to last in the given table.

But when extra_bits * reaches its limit of 17 (because LZX can only ensure reading 17 bits of * data at a time), we can only jump 128Kb at a time and have to start * using more and more position slots as each window size doubles. * * position_base[] is an index to the position slot bases * * extra_bits[] states how many bits of offset-from-base data is needed. * * They are calculated as follows: * extra_bits[i] = 0 where i < 4 * extra_bits[i] = floor(i/2)-1 where i >= 4 && i < 36 * extra_bits[i] = 17 where i >= 36 * position_base[0] = 0 * position_base[i] = position_base[i-1] + (1 << extra_bits[i-1]) */ static const unsigned int position_slots[11] = { 30, 32, 34, 36, 38, 42, 50, 66, 98, 162, 290 };

Brown. You may use this program, or * code or tables extracted from it, as desired without restriction. * * First, the polynomial itself and its table of feedback terms.

In our * implementation, that means shifting towards the right. Why do we * do it this way? Because the calculated CRC must be transmitted in * order from highest-order term to lowest-order term. UARTs transmit * characters in order from LSB to MSB. By storing the CRC this way * we hand it to the UART in the order low-byte to high-byte; the UART * sends each low-bit to hight-bit; and the result is transmission bit * by bit from highest- to lowest-order term without requiring any bit * shuffling on our part. Reception works similarly * * The feedback terms table consists of 256, 32-bit entries. Notes * * The table can be generated at runtime if desired; code to do so * is shown later. It might not be obvious, but the feedback * terms simply represent the results of eight shift/xor opera * tions for all combinations of data and CRC register values * * The values must be right-shifted by eight bits by the "updcrc * logic; the shift must be unsigned (bring in zeroes).

It is also designed to be easily embeddable, stable, robust and resource-efficient. The library is not intended as a generalised "any archiver" interface. Users of the library must explicitly choose the format they intend to work with. All special features of the above formats will be covered as fully as possible -- for example, CAB's multi-part cabinet sets, or CHM's fast lookup indices. All compression methods used by the formats will be implemented as completely as possible. However, other than what is required for access to these formats and their features, no other functionality is intended. There is no file metadata translation functionality. All file I/O is abstracted, although a default implementation using the standard C library is provided. DOCUMENTATION The API documentation is stored in the doc/ directory. It is generated automatically from mspack.h with doxygen. It is also available online at http://www.cabextract.org.uk/libmspack/doc/ BUILDING / INSTALLING ./configure make make install This will install the main libmspack library and mspack.h header file. Some other libraries and executables are built, but not installed. If building from the Subversion repository, running rebuild.sh will create all the automatically generated files like the configure script, and will then ./configure, make and make distcheck. Running cleanup.sh will perform a thorough clean, deleting all automatically generated files. In addition to gcc, you also need the following for building from Subversion: - at least autoconf 2.57 - at least automake 1.7 - libtool This is an alpha release. Unless you are in a position to package the libmspack library for the environment you intend to run your application, it is recommended that you do not rely on users of your software having the binary library installed and instead you should include the libmspack source files directly in your application's build environment. LEGAL ISSUES The the best of my knowledge, libmspack does not infringe on any compression or decompression patents. However, this is not legal advice, and it is recommended that you perform your own patent search. libmspack is licensed under the LGPL - see COPYING.LIB in this directory. The LGPL requires you to build libmspack as a stand alone library then link your code to it using a linker. I personally grant you some extra rights: you can incorporate libmspack's source code wholly or partially in your own code, without having to build and link libmspack as an independent library, provided you meet ALL of the following conditions: 1. ANY modifications to the existing libmspack source code are published and distributed under the LGPL license. 2. You MUST NOT use libmspack function calls, structures or definitions unless they are defined in the public library interface "mspack.h". 3. When distributing your code, you MUST make clear your code uses libmspack, and either include the full libmspack distribution with your code, or provide access to it as per clause 4 of the LGPL. EXAMPLE CODE There are a number of useful programs in the test/ directory which exercise and demonstrate libmspack's features. cabd_c10 - Tests the CAB decompressor on the C10 collection. cabd_compare - Compares the CAB decompressor with Microsoft's EXTRACT.EXE cabd_md5 - Prints the MD5 checksums of all files within a CAB file/set. cabd_memory - An mspack_system implementation that reads/writes to memory. cabd_test - Regression tests for libmspack's CAB decompression. cabrip - Extracts any CAB files embedded in another file. chmd_compare - Compares the CHM decompressor to Microsoft's HH.EXE chmd_find - Fast-finds a file within a CHM file. chmd_md5 - Prints the MD5 checksums of all files within a CHM file. chmd_order - Tests extracting files in a CHM file in four different ways. chminfo - Prints verbose information about CHM file structures. chmx - Extracts all files in a CHM file to disk. expand - Extracts an SZDD or KWAJ file. msdecompile_md5- Runs Microsoft's HH.EXE -DECOMPILE via WINE. msexpand_md5 - Runs Microsoft's EXTRACT.EXE via WINE. multifh - An mspack_system implementation that can simultaneously work on in-memory images, raw file descriptors, open file handles and regular disk files. Here is a simple example of usage, which will create a CAB decompressor, then use that to open an existing Microsoft CAB file called "example.cab", and list the names of all the files contained in that cab. #include #include #include int main() { struct mscab_decompressor *cabd; struct mscabd_cabinet *cab; struct mscabd_file *file; int test; MSPACK_SYS_SELFTEST(test); if (test != MSPACK_ERR_OK) exit(0); if ((cabd = mspack_create_cab_decompressor(NULL))) { if ((cab = cabd->open(cabd, "example.cab"))) { for (file = cab->files; file; file = file->next) { printf("%s\n", file->filename); } cabd->close(cabd, cab); } mspack_destroy_cab_decompressor(cabd); } return 0; } libmspack-0.4alpha/configure.ac0000644000175000017500000000236712145372236013554 00000000000000# -*- Autoconf -*- # Process this file with autoconf to produce a configure script.

[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 decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally. NO WARRANTY 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. END OF TERMS AND CONDITIONS How to Apply These Terms to Your New Libraries If you develop a new library, and you want it to be of the greatest possible use to the public, we recommend making it free software that everyone can redistribute and change. You can do so by permitting redistribution under these terms (or, alternatively, under the terms of the 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. Copyright (C) This library is free software; you can redistribute it and/or modify it under the terms of the GNU Lesser General Public License as published by the Free Software Foundation; either version 2.1 of the License, or (at your option) any later version. This library is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU Lesser General Public License for more details. You should have received a copy of the GNU Lesser General Public License along with this library; if not, write to the Free Software Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA Also add information on how to contact you by electronic and paper mail. You should also get your employer (if you work as a programmer) or your school, if any, to sign a "copyright disclaimer" for the library, if necessary. Here is a sample; alter the names: Yoyodyne, Inc., hereby disclaims all copyright interest in the library `Frob' (a library for tweaking knobs) written by James Random Hacker. , 1 April 1990 Ty Coon, President of Vice That's all there is to it! libmspack-0.4alpha/ChangeLog0000664000175000017500000004413112150671127013032 000000000000002013-05-27 Stuart Caie * test/oabx.c: added new example command for unpacking OAB files. 2013-05-17 Stuart Caie * mspack.h: Support for decompressing a new file format, the Exchange Offline Address Book (OAB). Thanks to David Woodhouse for writing the implementation. I've bumped the version to 0.4alpha in celebration. 2012-04-15 Stuart Caie * chmd_read_headers(): More thorough validation of CHM header values. Thanks to Sergei Trofimovich for finding sample files. * read_reset_table(): Better test for overflow. Thanks again to Sergei Trofimovich for generating a good example. * test/chminfo.c: this test program reads the reset table by itself and was also susceptible to the same overflow problems. 2012-03-16 Stuart Caie * Makefile.am, configure.ac: make the GCC warning flags conditional on using the GCC compiler. Thanks to Dagobert Michelsen for letting me know. 2011-11-25 Stuart Caie * lzxd_decompress(): Prevent matches that go beyond the start of the LZX stream. Thanks to Sergei Trofimovich for testing with valgrind and finding a corrupt sample file that exercises this scenario. 2011-11-23 Stuart Caie * chmd_fast_find(): add a simple check against infinite PGML loops. Thanks to Sergei Trofimovich for finding sample files. Multi-step PGML or PGMI infinite loops remain possible. 2011-06-17 Stuart Caie * read_reset_table(): wasn't reading the right offset for getting the LZX uncompressed length. Thanks to Sergei Trofimovich for finding the bug. 2011-05-31 Stuart Caie * kwajd.c, mszipd.c: KWAJ type 4 files (MSZIP) are now supported. Thanks to Clive Turvey for sending me the format details. * doc/szdd_kwaj_format.html: Updated documentation to cover KWAJ's MSZIP compression. 2011-05-11 Stuart Caie * cabd_find(): rethought how large vs small file support is handled, as users were getting "library not compiled to support large files" message on some small files. Now checks for actual off_t overflow, rather than trying to preempt it. 2011-05-10: Stuart Caie * chmd.c: implemented fast_find() * test/chmx.c: removed the multiple extraction orders, now it just extracts in the fastest order * test/chmd_order.c: new program added to test that different extraction orders don't affect the results of extraction * test/chmd_find.c: new program to test that fast_find() works. Either supply your own filename to find, or it will try finding every file in the CHM. * configure.ac: because CHM fast find requires case-insensitive comparisons, tolower() or towlower() are used where possible. These functions and their headers are checked for. * mspack.h: exposed struct mschmd_sec_mscompressed's spaninfo and struct mschmd_header's first_pmgl, last_pmgl and chunk_cache to the world. Check that the CHM decoder version is v2 or higher before using them. * system.c: set CHM decoder version to v2 2011-04-27: Stuart Caie * many files: Made C++ compilers much happier with libmspack. Changed char * to const char * where possible. * mspack.h: Changed user-supplied char * to const char *. Unless you've written your own mspack_system implementation, you will likely be unaffected. If you have written your own mspack_system implementation: 1: change open() so it takes a const char *filename 2: change message() so it takes a const char *format If you cast your function into the mspack_system struct, you can change the cast instead of the function. 2011-04-27: Stuart Caie * Makefile.am: changed CFLAGS from "-Wsign-compare -Wconversion -pedantic" to "-W -Wno-unused". This enables more warnings, and disables these specific warnings which are now a hinderance. 2011-04-27: Stuart Caie * test/cabrip.c, test/chminfo.c: used macros from system.h for printing offsets and reading 64-bit values, rather than reinvent the wheel. * cabd_can_merge_folders(): declare variables at the start of a block so older C compilers won't choke. * cabd_find(): avoid compiler complaints about non-initialised variables. We know they'll get initialised before use, but the compiler can't reverse a state machine to draw the same conclusion. 2011-04-26: Stuart Caie * configure.ac, mspack/system.h: Added a configure test to get the size of off_t. If off_t is 8 bytes or more, we presume this system has large file support. This fixes LFS detection for Fedora x86_64 and Darwin/Mac OS X, neither of which declare FILESIZEBITS in . It's not against the POSIX standard to do this: "A definition of [FILESIZEBITS] shall be omitted from the header on specific implementations where the corresponding value is equal to or greater than the stated minimum, but where the value can vary depending on the file to which it is applied." (http://pubs.opengroup.org/onlinepubs/009695399/basedefs/limits.h.html) Thanks to Edward Sheldrake for the patch. 2011-04-26: Stuart Caie * chmd.c: all 64-bit integer reads are now consolidated into the read_off64() function * chmd_read_headers(): this function has been made resilient against accessing memory past the end of a chunk. Thanks to Sergei Trofimovich for sending me examples and analysis. * chmd_init_decomp(): this function now reads the SpanInfo file if the ResetTable file isn't available, it also checks that each system file it needs is large enough before accessing it, and some of its code has been split into several new functions: find_sys_file(), read_reset_table() and read_spaninfo() 2011-04-26: Stuart Caie * mspack.h, chmd.c: now reads the SpanInfo system file if the ResetTable file isn't available. This adds a new spaninfo pointer into struct mschmd_sec_mscompressed 2011-04-26: Stuart Caie * test/chminfo.c: more sanity checks for corrupted CHM files where entries go past the end of a PGML/PGMI chunk, thanks to Sergei Trofimovich for sending me examples and analysis. 2011-04-25: Stuart Caie * cabd_merge(): Drew D'Addesio showed me spanning cabinets which don't have all the CFFILE entries they should, but otherwise have all necessary data for extraction. Changed the merging folders test to be less strict; if folders don't exactly match, warn which files are missing, but allow merging if at least one necessary file is present. 2010-09-24: Stuart Caie * readhuff.h: Don't let build_decode_table() allow empty trees. It's meant to be special case just for the LZX length tree, so move that logic out to the LZX code. Thanks to Danny Kroshin for discovering the bug. * lzxd.c: Allow empty length trees, but not other trees. If the length tree is empty, fail if asked to decode a length symbol. Again, thanks to Danny Kroshin for discovering the bug. 2010-09-20: Stuart Caie * Makefile.am: Set EXTRA_DIST so it doesn't include .svn directories in the distribution, but does include docs. 2010-09-20: Stuart Caie * Makefile.am, configure.ac: Use modern auto* practises; turn on automake silent rules where possible, use "m4" directory for libtool macros, use LT_INIT instead of AC_PROG_LIBTOOL and use AM_CPPFLAGS instead of INCLUDES. Thanks to Sergei Trofimovich for the patch. 2010-09-15: Stuart Caie * many files: Made the code compile with C++ - Renamed all 'this' variables/parameters to 'self' - Added casts to all memory allocations. - Added extern "C" to header files with extern declarations. - Made system.c include system.h. - Changed the K&R-style headers to ANSI-style headers in md5.c 2010-08-04: Stuart Caie * many files: removed unnecessary include 2010-07-19: Stuart Caie * cabd_md5.c, chmd_md5.c: Replace writing files to disk then MD5summing them, with an MD5summer built into mspack_system. Much, much faster results. * qtmd_decompress(): Robert Riebisch pointed out a Quantum data integrity check that could never be tripped, because frame_todo is unsigned, so it will never be decremented below zero. Replaced the check with one that assumes that decrementing past zero wraps frame_todo round to a number more than its maximum value (QTM_FRAME_SIZE). 2010-07-18: Stuart Caie * cabd.c: Special logic to pass cabd_sys_read() errors back to cabd_extract() wasn't compatible with the decompressor logic of returning the same error repeatedly once unpacking fails. This meant that if decompressing failed because of a read error, then the next file in the same folder would come back as "no error", but the decompressed wouldn't have even attempted to decompress the file. Added a new state variable, read_error, with the same lifespan as a decompressor, to pass the underlying reason for MSPACK_ERR_READ errors back. * mszipd.c: improve MS-ZIP recovery by saving all the bytes decoded prior to a block failing. This requires remembering how far we got through the block, so the code has been made slightly slower (about 0.003 seconds slower per gigabyte unpacked) by removing the local variable window_posn and keeping it in the state structure instead. 2010-07-16: Stuart Caie * Makefile.am: strange interactions. When -std=c99 is used, my Ubuntu's (libc6-dev 2.11.1-0ubuntu7.2) does NOT define fseeko() unless _LARGEFILE_SOURCE is also defined. But configure always uses -std=gnu99, not -std=c99, so its test determines _LARGEFILE_SOURCE isn't needed but HAVE_FSEEKO is true. The implicit fseeko definition has a 32-bit rather than 64-bit offset, which means the mode parameter is interpreted as part of the offset, and the mode is taken from the stack, which is generally 0 (SEEK_SET). This breaks all SEEK_CURs. The code works fine when -std=c99 is not set, so just remove it for the time being. 2010-07-12: Stuart Caie * system.c: Reject reading/writing a negative number of bytes. * chmd.c: allow zero-length files to be seen. Previously they were skipped because they were mistaken for directory entries. 2010-07-08: Stuart Caie * qtmd.c: Larry Frieson found an important bug in the Quantum decoder. Window wraps flush all unwritten data to disk. However, sometimes less data is needed, which makes out_bytes negative, which is then passed to write(). Some write() implementations treat negative sizes it as a large positive integer and segfault trying to write the buffer. * Makefile.am, test/*.c: fixed automake file so that the package passes a "make distcheck". 2010-07-07: Stuart Caie * doc/szdd_kwaj_format.html: explain SZDD/KWAJ file format. * lzssd.c: fixed SZDD decompression bugs. * test/chmd_compare: Add scripts for comparing chmd_md5 against Microsoft's own code. * test/chmd_md5.c: remove the need to decompress everything twice, as this is already in chmx.c if needed. 2010-07-06: Stuart Caie * many files: added SZDD and KWAJ decompression support. 2010-06-18: Stuart Caie * system.h: expanded the test for 64-bit largefile support so it also works on 64-bit native operating systems where you don't have to define _FILE_OFFSET_BITS. 2010-06-17: Stuart Caie * libmspack.pc.in: Added pkg-config support. Thanks to Patrice Dumas for the patch. 2010-06-14: Stuart Caie * qtmd.c, lzxd.c, mszipd.c: created new headers, readbits.h and readhuff.h, which bundle up the bit-reading and huffman-reading code found in the MSZIP, LZX and Quantum decoders. 2010-06-11: Stuart Caie * qtmd_static_init(): Removed function in favour of static const tables, same rationale as for lzxd_static_init(). * qtmd_read_input(), zipd_read_input(): After testing against my set of CABs from the wild, I've found both these functions _need_ an extra EOF flag, like lzxd_read_input() has. So I've added it. This means CABs get decoded properly AND there's no reading fictional bytes. 2010-06-03: Stuart Caie * test/cabd_md5.c: updated this so it has better output and doesn't need to be in the same directory as the files for multi- part sets. 2010-05-20: Stuart Caie * qtmd_read_input(), zipd_read_input(): Both these functions are essentially copies of lzxd_read_input(), but that has a feature they don't have - an extra EOF flag. So if EOF is encountered (sys->read() returns 0 bytes), these don't pass on the error. Their respective bit-reading functions that called them then go on to access at least one byte of the input buffer, which doesn't exist as sys->read() returned 0. Thanks to Michael Vidrevich for spotting this and providing a test case. 2010-05-20: Stuart Caie * system.h: It turns out no configure.ac tests are needed to decide between __func__ and __FUNCTION__, so I put the standard one (__func__) back into the D() macro, along with some special-case ifdefs for old versions of GCC. * lzxd_static_init(): Removed function in favour of static const tables. Jorge Lodos thinks it causes multithreading problems, I disagree. However, there are speed benefits to declaring the tables as static const. * cabd_init_decomp(): Fixed code which never runs but would write to a null pointer if it could. Changed it to an assert() as it will only trip if someone rewrites the internals of cabd.c. Thanks to Jorge Lodos for finding it. * inflate(): Fixed an off-by-one error: if the LITERAL table emitted code 286, this would read one byte past the end of lit_extrabits[]. Thanks to Jorge Lodos for finding it. 2010-05-06: Stuart Caie * test/cabrip.c, test/chminfo.c: add fseeko() support 2009-06-01: Stuart Caie * README: clarify the extended license terms * doc, Makefile.am: make the doxygen makefile work when using an alternate build directory 2006-09-20: Stuart Caie * system.h: I had a choice of adding more to configure.ac to test for __func__ and __FUNCTION__, or just removing __FUNCTION__ from the D() macro. I chose the latter. * Makefile.am: Now the --enable-debug in configure will actually apply -DDEBUG to the sources. 2006-09-20: Stuart Caie * qtmd_decompress(): Fixed a major bug in the QTM decoder, as reported by Tomasz Kojm last year. Removed the restriction on window sizes as a result. Correctly decodes the XLVIEW cabinets. 2006-08-31: Stuart Caie * lzxd_decompress(): Two major bugs fixed. Firstly, the R0/R1/R2 local variables weren't set to 1 after lzxd_reset_state(). Secondly, the LZX decompression stream can sometimes become odd-aligned (after an uncompressed block) and the next 16 bit fetch needs to be split across two input buffers, ENSURE_BITS() didn't cover this case. Many thanks to Igor Glucksmann for discovering both these bugs. 2005-06-30: Stuart Caie * cabd_search(): fixed problems with searching files > 4GB for cabinets. 2005-06-23: Stuart Caie * qtmd_init(): The QTM decoder is broken for QTM streams with a window size less than the frame size. Until this is fixed, fail to initialise QTM window sizes less than 15. Thanks to Tomasz Kojm for finding the bug. 2005-03-22: Stuart Caie * system.h: now undefs "read", as the latest glibc defines read() as a macro which messes everything up. Thanks to Ville Skytt for the update. 2005-03-14: Stuart Caie * test/multifh.c: write an mspack_system implementation that can handle normal disk files, open file handles, open file descriptors and raw memory all at the same time. 2005-02-24: Stuart Caie * chmd_read_headers(): avoid infinite loop when chmhs1_ChunkSize is zero. Thanks to Serge Semashko for the research and discovery. 2005-02-18: Stuart Caie * mspack.h: renamed the "interface" parameter of mspack_version() to "entity", as interface is a reserved word in C++. Thanks to Yuriy Z for the discovery. 2004-12-09: Stuart Caie * lzss.h, szdd.h, szddd.h: more work on the SZDD/LZSS design. 2004-06-12: Stuart Caie * lzxd_static_init(): removed write to lzxd_extra_bits[52], thanks to Nigel Horne from the ClamAV project. 2004-04-23: Stuart Caie * mspack.h: changed 'this' parameters to 'self' to allow compiling in C++ compilers, thanks to Michal Cihar for the suggestion. * mspack.h, system.h, mspack.def, winbuild.sh: integrated some changes from Petr Blahos to let libmspack build as a Win32 DLL. * chmd_fast_find(): added the first part of this code, and comments sufficient to finish it :) 2004-04-08 Stuart Caie * test/chminfo.c: added a program for dumping useful data from CHM files, e.g. index entries and reset tables. I wrote this a while ago for investigating a corrupt cabinet, but I never committed it. 2004-03-26 Stuart Caie * test/cabd_memory.c: added a new test example which shows an mspack_system implementation that reads and writes from memory only, no file I/O. Even the source code has a little cab file embedded in it. 2004-03-10 Stuart Caie * cabd.c: updated the location of the CAB SDK. * cabd.c: changed a couple of MSPACK_ERR_READ errors not based on read() failures into MSPACK_ERR_DATAFORMAT errors. * mszipd_decompress(): repair mode now aborts after writing a repaired block if the error was a hard error (e.g. read error, out of blocks, etc) 2004-03-08 Stuart Caie * Makefile.am: now builds and installs a versioned library. * mszipd.c: completed a new MS-ZIP and inflate implementation. * system.c: added mspack_version() and committed to a versioned ABI for the library. * cabd.c: made mszip repair functionality work correctly. * cabd.c: now identifies invalid block headers * doc/: API documentation is now included with the library, not just on the web. * chmd.c: fixed error messages and 64-bit debug output. * chmd.c: now also catches NULL files in section 1. * test/chmx.c: now acts more like cabextract. 2003-08-29 Stuart Caie * ChangeLog: started keeping a ChangeLog :) libmspack-0.4alpha/INSTALL0000644000175000017500000003660012151103170012276 00000000000000Installation Instructions ************************* Copyright (C) 1994-1996, 1999-2002, 2004-2011 Free Software Foundation, Inc. Copying and distribution of this file, with or without modification, are permitted in any medium without royalty provided the copyright notice and this notice are preserved. This file is offered as-is, without warranty of any kind. Basic Installation ================== Briefly, the shell commands `./configure; make; make install' should configure, build, and install this package. The following more-detailed instructions are generic; see the `README' file for instructions specific to this package. Some packages provide this `INSTALL' file but do not implement all of the features documented below. The lack of an optional feature in a given package is not necessarily a bug. More recommendations for GNU packages can be found in *note Makefile Conventions: (standards)Makefile Conventions. The `configure' shell script attempts to guess correct values for various system-dependent variables used during compilation. It uses those values to create a `Makefile' in each directory of the package. It may also create one or more `.h' files containing system-dependent definitions. Finally, it creates a shell script `config.status' that you can run in the future to recreate the current configuration, and a file `config.log' containing compiler output (useful mainly for debugging `configure'). It can also use an optional file (typically called `config.cache' and enabled with `--cache-file=config.cache' or simply `-C') that saves the results of its tests to speed up reconfiguring. Caching is disabled by default to prevent problems with accidental use of stale cache files. If you need to do unusual things to compile the package, please try to figure out how `configure' could check whether to do them, and mail diffs or instructions to the address given in the `README' so they can be considered for the next release. If you are using the cache, and at some point `config.cache' contains results you don't want to keep, you may remove or edit it. The file `configure.ac' (or `configure.in') is used to create `configure' by a program called `autoconf'. You need `configure.ac' if you want to change it or regenerate `configure' using a newer version of `autoconf'. The simplest way to compile this package is: 1. `cd' to the directory containing the package's source code and type `./configure' to configure the package for your system. Running `configure' might take a while. While running, it prints some messages telling which features it is checking for. 2. Type `make' to compile the package. 3. Optionally, type `make check' to run any self-tests that come with the package, generally using the just-built uninstalled binaries. 4. Type `make install' to install the programs and any data files and documentation. When installing into a prefix owned by root, it is recommended that the package be configured and built as a regular user, and only the `make install' phase executed with root privileges. 5. Optionally, type `make installcheck' to repeat any self-tests, but this time using the binaries in their final installed location. This target does not install anything. Running this target as a regular user, particularly if the prior `make install' required root privileges, verifies that the installation completed correctly. 6. You can remove the program binaries and object files from the source code directory by typing `make clean'. To also remove the files that `configure' created (so you can compile the package for a different kind of computer), type `make distclean'. There is also a `make maintainer-clean' target, but that is intended mainly for the package's developers. If you use it, you may have to get all sorts of other programs in order to regenerate files that came with the distribution. 7. Often, you can also type `make uninstall' to remove the installed files again. In practice, not all packages have tested that uninstallation works correctly, even though it is required by the GNU Coding Standards. 8. Some packages, particularly those that use Automake, provide `make distcheck', which can by used by developers to test that all other targets like `make install' and `make uninstall' work correctly. This target is generally not run by end users. Compilers and Options ===================== Some systems require unusual options for compilation or linking that the `configure' script does not know about. Run `./configure --help' for details on some of the pertinent environment variables. You can give `configure' initial values for configuration parameters by setting variables in the command line or in the environment. Here is an example: ./configure CC=c99 CFLAGS=-g LIBS=-lposix *Note Defining Variables::, for more details. Compiling For Multiple Architectures ==================================== You can compile the package for more than one kind of computer at the same time, by placing the object files for each architecture in their own directory. To do this, you can use GNU `make'. `cd' to the directory where you want the object files and executables to go and run the `configure' script. `configure' automatically checks for the source code in the directory that `configure' is in and in `..'. This is known as a "VPATH" build. With a non-GNU `make', it is safer to compile the package for one architecture at a time in the source code directory. After you have installed the package for one architecture, use `make distclean' before reconfiguring for another architecture. On MacOS X 10.5 and later systems, you can create libraries and executables that work on multiple system types--known as "fat" or "universal" binaries--by specifying multiple `-arch' options to the compiler but only a single `-arch' option to the preprocessor. Like this: ./configure CC="gcc -arch i386 -arch x86_64 -arch ppc -arch ppc64" \ CXX="g++ -arch i386 -arch x86_64 -arch ppc -arch ppc64" \ CPP="gcc -E" CXXCPP="g++ -E" This is not guaranteed to produce working output in all cases, you may have to build one architecture at a time and combine the results using the `lipo' tool if you have problems. Installation Names ================== By default, `make install' installs the package's commands under `/usr/local/bin', include files under `/usr/local/include', etc. You can specify an installation prefix other than `/usr/local' by giving `configure' the option `--prefix=PREFIX', where PREFIX must be an absolute file name. You can specify separate installation prefixes for architecture-specific files and architecture-independent files. If you pass the option `--exec-prefix=PREFIX' to `configure', the package uses PREFIX as the prefix for installing programs and libraries. Documentation and other data files still use the regular prefix. In addition, if you use an unusual directory layout you can give options like `--bindir=DIR' to specify different values for particular kinds of files. Run `configure --help' for a list of the directories you can set and what kinds of files go in them. In general, the default for these options is expressed in terms of `${prefix}', so that specifying just `--prefix' will affect all of the other directory specifications that were not explicitly provided. The most portable way to affect installation locations is to pass the correct locations to `configure'; however, many packages provide one or both of the following shortcuts of passing variable assignments to the `make install' command line to change installation locations without having to reconfigure or recompile. The first method involves providing an override variable for each affected directory. For example, `make install prefix=/alternate/directory' will choose an alternate location for all directory configuration variables that were expressed in terms of `${prefix}'. Any directories that were specified during `configure', but not in terms of `${prefix}', must each be overridden at install time for the entire installation to be relocated. The approach of makefile variable overrides for each directory variable is required by the GNU Coding Standards, and ideally causes no recompilation. However, some platforms have known limitations with the semantics of shared libraries that end up requiring recompilation when using this method, particularly noticeable in packages that use GNU Libtool. The second method involves providing the `DESTDIR' variable. For example, `make install DESTDIR=/alternate/directory' will prepend `/alternate/directory' before all installation names. The approach of `DESTDIR' overrides is not required by the GNU Coding Standards, and does not work on platforms that have drive letters. On the other hand, it does better at avoiding recompilation issues, and works well even when some directory options were not specified in terms of `${prefix}' at `configure' time. Optional Features ================= If the package supports it, you can cause programs to be installed with an extra prefix or suffix on their names by giving `configure' the option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'. Some packages pay attention to `--enable-FEATURE' options to `configure', where FEATURE indicates an optional part of the package. They may also pay attention to `--with-PACKAGE' options, where PACKAGE is something like `gnu-as' or `x' (for the X Window System). The `README' should mention any `--enable-' and `--with-' options that the package recognizes. For packages that use the X Window System, `configure' can usually find the X include and library files automatically, but if it doesn't, you can use the `configure' options `--x-includes=DIR' and `--x-libraries=DIR' to specify their locations. Some packages offer the ability to configure how verbose the execution of `make' will be. For these packages, running `./configure --enable-silent-rules' sets the default to minimal output, which can be overridden with `make V=1'; while running `./configure --disable-silent-rules' sets the default to verbose, which can be overridden with `make V=0'. Particular systems ================== On HP-UX, the default C compiler is not ANSI C compatible. If GNU CC is not installed, it is recommended to use the following options in order to use an ANSI C compiler: ./configure CC="cc -Ae -D_XOPEN_SOURCE=500" and if that doesn't work, install pre-built binaries of GCC for HP-UX. HP-UX `make' updates targets which have the same time stamps as their prerequisites, which makes it generally unusable when shipped generated files such as `configure' are involved. Use GNU `make' instead. On OSF/1 a.k.a. Tru64, some versions of the default C compiler cannot parse its `' header file. The option `-nodtk' can be used as a workaround. If GNU CC is not installed, it is therefore recommended to try ./configure CC="cc" and if that doesn't work, try ./configure CC="cc -nodtk" On Solaris, don't put `/usr/ucb' early in your `PATH'. This directory contains several dysfunctional programs; working variants of these programs are available in `/usr/bin'. So, if you need `/usr/ucb' in your `PATH', put it _after_ `/usr/bin'. On Haiku, software installed for all users goes in `/boot/common', not `/usr/local'. It is recommended to use the following options: ./configure --prefix=/boot/common Specifying the System Type ========================== There may be some features `configure' cannot figure out automatically, but needs to determine by the type of machine the package will run on. Usually, assuming the package is built to be run on the _same_ architectures, `configure' can figure that out, but if it prints a message saying it cannot guess the machine type, give it the `--build=TYPE' option. TYPE can either be a short name for the system type, such as `sun4', or a canonical name which has the form: CPU-COMPANY-SYSTEM where SYSTEM can have one of these forms: OS KERNEL-OS See the file `config.sub' for the possible values of each field. If `config.sub' isn't included in this package, then this package doesn't need to know the machine type. If you are _building_ compiler tools for cross-compiling, you should use the option `--target=TYPE' to select the type of system they will produce code for. If you want to _use_ a cross compiler, that generates code for a platform different from the build platform, you should specify the "host" platform (i.e., that on which the generated programs will eventually be run) with `--host=TYPE'. Sharing Defaults ================ If you want to set default values for `configure' scripts to share, you can create a site shell script called `config.site' that gives default values for variables like `CC', `cache_file', and `prefix'. `configure' looks for `PREFIX/share/config.site' if it exists, then `PREFIX/etc/config.site' if it exists. Or, you can set the `CONFIG_SITE' environment variable to the location of the site script. A warning: not all `configure' scripts look for a site script. Defining Variables ================== Variables not defined in a site shell script can be set in the environment passed to `configure'. However, some packages may run configure again during the build, and the customized values of these variables may be lost. In order to avoid this problem, you should set them in the `configure' command line, using `VAR=value'. For example: ./configure CC=/usr/local2/bin/gcc causes the specified `gcc' to be used as the C compiler (unless it is overridden in the site shell script). Unfortunately, this technique does not work for `CONFIG_SHELL' due to an Autoconf bug. Until the bug is fixed you can use this workaround: CONFIG_SHELL=/bin/bash /bin/bash ./configure CONFIG_SHELL=/bin/bash `configure' Invocation ====================== `configure' recognizes the following options to control how it operates. `--help' `-h' Print a summary of all of the options to `configure', and exit. `--help=short' `--help=recursive' Print a summary of the options unique to this package's `configure', and exit. The `short' variant lists options used only in the top level, while the `recursive' variant lists options also present in any nested packages. `--version' `-V' Print the version of Autoconf used to generate the `configure' script, and exit. `--cache-file=FILE' Enable the cache: use and save the results of the tests in FILE, traditionally `config.cache'. FILE defaults to `/dev/null' to disable caching. `--config-cache' `-C' Alias for `--cache-file=config.cache'. `--quiet' `--silent' `-q' Do not print messages saying which checks are being made. To suppress all normal output, redirect it to `/dev/null' (any error messages will still be shown). `--srcdir=DIR' Look for the package's source code in directory DIR. Usually `configure' can determine that directory automatically. `--prefix=DIR' Use DIR as the installation prefix. *note Installation Names:: for more details, including other options available for fine-tuning the installation locations. `--no-create' `-n' Run the configure checks, but stop before creating any output files. `configure' also accepts some other, not widely useful, options. Run `configure --help' for more details. libmspack-0.4alpha/NEWS0000644000175000017500000000000007730100563011737 00000000000000libmspack-0.4alpha/TODO0000644000175000017500000000037611742523543011755 00000000000000* CAB compression * cabd_find(): if many bytes are missing from the end of a cabinet, it should still find it * CHM compression * HLP: everything * LIT: everything * SZDD/KWAJ: compression * WIM: everything * chm: make chunk cache size user-controllable libmspack-0.4alpha/config.guess0000755000175000017500000012743212151103152013571 00000000000000#! /bin/sh # Attempt to guess a canonical system name. # Copyright (C) 1992, 1993, 1994, 1995, 1996, 1997, 1998, 1999, # 2000, 2001, 2002, 2003, 2004, 2005, 2006, 2007, 2008, 2009, 2010, # 2011, 2012 Free Software Foundation, Inc. timestamp='2012-02-10' # This file is free software; you can redistribute it and/or modify it # under the terms of the GNU General Public License as published by # the Free Software Foundation; either version 2 of the License, or # (at your option) any later version. # # This program is distributed in the hope that it will be useful, but # WITHOUT ANY WARRANTY; without even the implied warranty of # MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
