First pass at adding built-in zlib support for those systems that
don't normally have it (notably, Windows). I've only tested in Linux so far. git-svn-id: svn://svn.code.sf.net/p/stella/code/trunk@1926 8b62c5a3-ac7e-4cc8-8f21-d9a121418aba

Compresses the source buffer into the destination buffer. The level

parameter has the same meaning as in deflateInit. sourceLen is the byte

length of the source buffer. Upon entry, destLen is the total size of the

destination buffer, which must be at least 0.1% larger than sourceLen plus
|

|
12 bytes. Upon exit, destLen is the actual size of the compressed buffer.
|
||||||
|
|
||||||
|
compress2 returns Z_OK if success, Z_MEM_ERROR if there was not enough
|

|
memory, Z_BUF_ERROR if there was not enough room in the output buffer,
|
||||||
|
Z_STREAM_ERROR if the level parameter is invalid.

Generate tables for a byte-wise 32-bit CRC calculation on the polynomial:
|
||||||
|
x^32+x^26+x^23+x^22+x^16+x^12+x^11+x^10+x^8+x^7+x^5+x^4+x^2+x+1.
|
||||||
|
|
||||||
|
Polynomials over GF(2) are represented in binary, one bit per coefficient,
|
||||||
|
with the lowest powers in the most significant bit. Then adding polynomials
|
||||||
|
is just exclusive-or, and multiplying a polynomial by x is a right shift by
|
||||||
|
one. If we call the above polynomial p, and represent a byte as the
|
||||||
|
polynomial q, also with the lowest power in the most significant bit (so the
|
||||||
|
byte 0xb1 is the polynomial x^7+x^3+x+1), then the CRC is (q*x^32) mod p,
|
||||||
|
where a mod b means the remainder after dividing a by b.
|
||||||
|
|
||||||
|
This calculation is done using the shift-register method of multiplying and
|
||||||
|
taking the remainder. The register is initialized to zero, and for each
|
||||||
|
incoming bit, x^32 is added mod p to the register if the bit is a one (where
|
||||||
|
x^32 mod p is p+x^32 = x^26+...+1), and the register is multiplied mod p by
|
||||||
|
x (which is shifting right by one and adding x^32 mod p if the bit shifted
|
||||||
|
out is a one). We start with the highest power (least significant bit) of
|
||||||
|
q and repeat for all eight bits of q.
|
||||||
|
|
||||||
|
The first table is simply the CRC of all possible eight bit values. This is
|
||||||
|
all the information needed to generate CRCs on data a byte at a time for all
|
||||||
|
combinations of CRC register values and incoming bytes. The remaining tables
|
||||||
|
allow for word-at-a-time CRC calculation for both big-endian and little-
|
||||||
|
endian machines, where a word is four bytes.

When large enough input and output buffers are supplied to inflate(), for

BAD -- error in block data
|
||||||
|
|
||||||
|
Notes:
|
||||||
|
|
||||||
|
- The maximum input bits used by a length/distance pair is 15 bits for the
|
||||||
|
length code, 5 bits for the length extra, 15 bits for the distance code,
|
||||||
|
and 13 bits for the distance extra. This totals 48 bits, or six bytes.
|
||||||
|
Therefore if strm->avail_in >= 6, then there is enough input to avoid
|
||||||
|
checking for available input while decoding.
|
||||||
|
|
||||||
|
- The maximum bytes that a single length/distance pair can output is 258
|
||||||
|
bytes, which is the maximum length that can be coded. inflate_fast()
|
||||||
|
requires strm->avail_out >= 258 for each loop to avoid checking for
|
||||||
|
output space.

/*
|
||||||
|
Process a set of code lengths to create a canonical Huffman code. The
|
||||||
|
code lengths are lens[0..codes-1]. Each length corresponds to the
|
||||||
|
symbols 0..codes-1. The Huffman code is generated by first sorting the
|
||||||
|
symbols by length from short to long, and retaining the symbol order
|
||||||
|
for codes with equal lengths. Then the code starts with all zero bits
|
||||||
|
for the first code of the shortest length, and the codes are integer
|
||||||
|
increments for the same length, and zeros are appended as the length
|
||||||
|
increases. For the deflate format, these bits are stored backwards
|
||||||
|
from their more natural integer increment ordering, and so when the
|
||||||
|
decoding tables are built in the large loop below, the integer codes
|
||||||
|
are incremented backwards.
|
||||||
|
|
||||||
|
This routine assumes, but does not check, that all of the entries in
|
||||||
|
lens[] are in the range 0..MAXBITS. The caller must assure This.
|
||||||
|
1..MAXBITS is interpreted as that code length. zero means that that
|
||||||
|
symbol does not occur in This code.
|
||||||
|
|
||||||
|
The codes are sorted by computing a count of codes for each length,
|
||||||
|
creating from that a table of starting indices for each length in the
|
||||||
|
sorted table, and then entering the symbols in order in the sorted
|
||||||
|
table. The sorted table is work[], with that space being provided by
|
||||||
|
the caller.
|
||||||
|
|
||||||
|
The length counts are used for other purposes as well, i.e. finding
|
||||||
|
the minimum and maximum length codes, determining if there are any
|
||||||
|
codes at all, checking for a valid set of lengths, and looking ahead
|
||||||

Create and fill in decoding tables. In This loop, the table being
|
||||||
|
filled is at next and has curr index bits. The code being used is huff
|
||||||
|
with length len. That code is converted to an index by dropping drop
|
||||||
|
bits off of the bottom. For codes where len is less than drop + curr,
|
||||||
|
those top drop + curr - len bits are incremented through all values to
|
||||||
|
fill the table with replicated entries.
|
||||||
|
|
||||||
|
root is the number of index bits for the root table. When len exceeds
|
||||||
|
root, sub-tables are created pointed to by the root entry with an index
|
||||||
|
of the low root bits of huff. This is saved in low to check for when a
|
||||||
|
new sub-table should be started. drop is zero when the root table is
|
||||||
|
being filled, and drop is root when sub-tables are being filled.
|
||||||
|
|
||||||
|
When a new sub-table is needed, it is necessary to look ahead in the
|
||||||
|
code lengths to determine what size sub-table is needed. The length
|
||||||
|
counts are used for This, and so count[] is decremented as codes are
|
||||||
|
entered in the tables.
|
||||||
|
|
||||||
|
used keeps track of how many table entries have been allocated from the
|
||||||
|
provided *table space. It is checked when a LENS table is being made
|
||||||
|
against the space in *table, ENOUGH, minus the maximum space needed by
|
||||||
|
the worst case distance code, MAXD. This should never happen, but the
|
||||||
|
sufficiency of ENOUGH has not been proven exhaustively, hence the check.
|
||||||
|
This assumes that when type == LENS, bits == 9.
|
||||||
|
|
||||||
|
sym increments through all symbols, and the loop terminates when
|
||||||
|
all codes of length max, i.e. all codes, have been processed. This
|
||||||
|
routine permits incomplete codes, so another loop after This one fills
|
||||||
|
in the rest of the decoding tables with invalid code markers.

ZLIB DATA COMPRESSION LIBRARY
|
||||||
|
|
||||||
|
zlib 1.2.3 is a general purpose data compression library. All the code is
|
||||||
|
thread safe. The data format used by the zlib library is described by RFCs
|
||||||
|
(Request for Comments) 1950 to 1952 in the files
|
||||||
|
http://www.ietf.org/rfc/rfc1950.txt (zlib format), rfc1951.txt (deflate format)
|
||||||
|
and rfc1952.txt (gzip format). These documents are also available in other
|
||||||
|
formats from ftp://ftp.uu.net/graphics/png/documents/zlib/zdoc-index.html
|
||||||
|
|
||||||
|
All functions of the compression library are documented in the file zlib.h
|
||||||
|
(volunteer to write man pages welcome, contact zlib@gzip.org). A usage example
|
||||||
|
of the library is given in the file example.c which also tests that the library
|
||||||
|
is working correctly. Another example is given in the file minigzip.c. The
|
||||||
|
compression library itself is composed of all source files except example.c and
|
||||||
|
minigzip.c.
|
||||||
|
|
||||||
|
To compile all files and run the test program, follow the instructions given at
|
||||||
|
the top of Makefile. In short "make test; make install" should work for most
|
||||||
|
machines. For Unix: "./configure; make test; make install". For MSDOS, use one
|
||||||
|
of the special makefiles such as Makefile.msc. For VMS, use make_vms.com.
|
||||||
|
|
||||||
|
Questions about zlib should be sent to <zlib@gzip.org>, or to Gilles Vollant
|
||||||
|
<info@winimage.com> for the Windows DLL version. The zlib home page is
|
||||||
|
http://www.zlib.org or http://www.gzip.org/zlib/ Before reporting a problem,
|
||||||
|
please check this site to verify that you have the latest version of zlib;
|
||||||
|
otherwise get the latest version and check whether the problem still exists or
|
||||||
|
not.
|
||||||
|
|
||||||
|
PLEASE read the zlib FAQ http://www.gzip.org/zlib/zlib_faq.html before asking
|
||||||
|
for help.
|
||||||
|
|
||||||
|
Mark Nelson <markn@ieee.org> wrote an article about zlib for the Jan. 1997
|
||||||
|
issue of Dr. Dobb's Journal; a copy of the article is available in
|
||||||
|
http://dogma.net/markn/articles/zlibtool/zlibtool.htm
|
||||||
|
|
||||||
|
The changes made in version 1.2.3 are documented in the file ChangeLog.
|
||||||
|
|
||||||
|
Unsupported third party contributions are provided in directory "contrib".
|
||||||
|
|
||||||
|
A Java implementation of zlib is available in the Java Development Kit
|
||||||
|
http://java.sun.com/j2se/1.4.2/docs/api/java/util/zip/package-summary.html
|
||||||
|
See the zlib home page http://www.zlib.org for details.
|
||||||
|
|
||||||
|
A Perl interface to zlib written by Paul Marquess <pmqs@cpan.org> is in the
|
||||||
|
CPAN (Comprehensive Perl Archive Network) sites
|
||||||
|
http://www.cpan.org/modules/by-module/Compress/
|
||||||
|
|
||||||
|
A Python interface to zlib written by A.M. Kuchling <amk@amk.ca> is
|
||||||
|
available in Python 1.5 and later versions, see
|
||||||
|
http://www.python.org/doc/lib/module-zlib.html
|
||||||
|
|
||||||
|
A zlib binding for TCL written by Andreas Kupries <a.kupries@westend.com> is
|
||||||
|
availlable at http://www.oche.de/~akupries/soft/trf/trf_zip.html
|
||||||
|
|
||||||
|
An experimental package to read and write files in .zip format, written on top
|
||||||
|
of zlib by Gilles Vollant <info@winimage.com>, is available in the
|
||||||
|
contrib/minizip directory of zlib.
|
||||||
|
|
||||||
|
|
||||||
|
Notes for some targets:
|
||||||
|
|
||||||
|
- For Windows DLL versions, please see win32/DLL_FAQ.txt
|
||||||
|
|
||||||
|
- For 64-bit Irix, deflate.c must be compiled without any optimization. With
|
||||||
|
-O, one libpng test fails. The test works in 32 bit mode (with the -n32
|
||||||
|
compiler flag). The compiler bug has been reported to SGI.
|
||||||
|
|
||||||
|
- zlib doesn't work with gcc 2.6.3 on a DEC 3000/300LX under OSF/1 2.1 it works
|
||||||
|
when compiled with cc.
|
||||||
|
|
||||||
|
- On Digital Unix 4.0D (formely OSF/1) on AlphaServer, the cc option -std1 is
|
||||||
|
necessary to get gzprintf working correctly. This is done by configure.
|
||||||
|
|
||||||
|
- zlib doesn't work on HP-UX 9.05 with some versions of /bin/cc. It works with
|
||||||
|
other compilers. Use "make test" to check your compiler.
|
||||||
|
|
||||||
|
- gzdopen is not supported on RISCOS, BEOS and by some Mac compilers.
|
||||||
|
|
||||||
|
- For PalmOs, see http://palmzlib.sourceforge.net/
|
||||||
|
|
||||||
|
- When building a shared, i.e. dynamic library on Mac OS X, the library must be
|
||||||
|
installed before testing (do "make install" before "make test"), since the
|
||||||
|
library location is specified in the library.
|
||||||

The deflate format used by zlib was defined by Phil Katz. The deflate
|
||||||
|
and zlib specifications were written by L. Peter Deutsch. Thanks to all the
|

people who reported problems and suggested various improvements in zlib;
|
||||||

they are too numerous to cite here.

Decompresses the source buffer into the destination buffer. sourceLen is
|

the byte length of the source buffer. Upon entry, destLen is the total
|
||||||
|
size of the destination buffer, which must be large enough to hold the

entire uncompressed data. (The size of the uncompressed data must have
|

been saved previously by the compressor and transmitted to the decompressor
|
||||||
|
by some mechanism outside the scope of this compression library.)
|
||||||
|
Upon exit, destLen is the actual size of the compressed buffer.

This function can be used to decompress a whole file at once if the
|

|
input file is mmap'ed.
|

uncompress returns Z_OK if success, Z_MEM_ERROR if there was not

enough memory, Z_BUF_ERROR if there was not enough room in the output

buffer, or Z_DATA_ERROR if the input data was corrupted.
