/*---------------------------------------------------------------------------
api.c
This module supplies an UnZip engine for use directly from C/C++
programs. The functions are:
UzpVer *UzpVersion(void);
void UzpVersion2(UzpVer2 *version)
int UzpMain(int argc, char *argv[]);
int UzpAltMain(int argc, char *argv[], UzpInit *init);
int UzpValidate(char *archive, int AllCodes);
void UzpFreeMemBuffer(UzpBuffer *retstr);
int UzpUnzipToMemory(char *zip, char *file, UzpOpts *optflgs,
UzpCB *UsrFuncts, UzpBuffer *retstr);
non-WINDLL only (a special WINDLL variant is defined in windll/windll.c):
int UzpGrep(char *archive, char *file, char *pattern, int cmd, int SkipBin,
UzpCB *UsrFuncts);
OS/2 only (for now):
int UzpFileTree(char *name, cbList(callBack), char *cpInclude[],
char *cpExclude[]);
You must define `DLL' in order to include the API extensions.

pattern = string to search for
cmd = 0 - case-insensitive search
1 - case-sensitve search
2 - case-insensitive, whole words only
3 - case-sensitive, whole words only
SkipBin = if true, skip any files that have control
characters other than CR, LF, or tab in the first
100 characters.
Returns: TRUE if a match is found
FALSE if no match is found
-1 on error
Comments: This does not pretend to be as useful as the standard
Unix grep, which returns the strings associated with a
particular pattern, nor does it search past the first
matching occurrence of the pattern.

/*
* crc_i386.S, optimized CRC calculation function for Zip and UnZip, not
* copyrighted by Paul Kienitz and Christian Spieler. Last revised 12 Oct 97.
*
* GRR 961110: incorporated Scott Field optimizations from win32/crc_i386.asm
* => overall 6% speedup in "unzip -tq" on 9MB zipfile (486-66)
*
* SPC 970402: revised for Rodney Brown's optimizations (32-bit-wide
* aligned reads for most of the data from buffer), can be
* disabled by defining the macro NO_32_BIT_LOADS
*
* SPC 971012: added Rodney Brown's additional tweaks for 32-bit-optimized
* CPUs (like the Pentium Pro, Pentium II, and probably some
* Pentium clones). This optimization is controlled by the
* preprocessor switch "__686" and is disabled by default.
* (This default is based on the assumption that most users
* do not yet work on a Pentium Pro or Pentium II machine ...)
*
* FLAT memory model assumed. Calling interface:
* - args are pushed onto the stack from right to left,
* - return value is given in the EAX register,
* - all other registers (with exception of EFLAGS) are preserved. (With
* GNU C 2.7.x, %edx and %ecx are `scratch' registers, but preserving
* them nevertheless adds only 4 single byte instructions.)
*
* This source generates the function
* ulg crc32(ulg crc, ZCONST uch *buf, ulg len).
*
* The loop unrolling can be disabled by defining the macro NO_UNROLLED_LOOPS.
* This results in shorter code at the expense of reduced performance.

/*
Generate a table 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

/*----------------------------------------------------------------*
| envargs - add default options from environment to command line
|----------------------------------------------------------------
| Author: Bill Davidsen, original 10/13/91, revised 23 Oct 1991.
| This program is in the public domain.
|----------------------------------------------------------------
| Minor program notes:
| 1. Yes, the indirection is a tad complex
| 2. Parentheses were added where not needed in some cases
| to make the action of the code less obscure.
|----------------------------------------------------------------
| UnZip notes: 24 May 92 ("v1.4"):
| 1. #include "unzip.h" for prototypes (24 May 92)
| 2. changed ch to type char (24 May 92)
| 3. added an ifdef to avoid Borland warnings (24 May 92)
| 4. included Rich Wales' mksargs() routine (for MS-DOS, maybe
| OS/2? NT?) (4 Dec 93)
| 5. added alternate-variable string envstr2 (21 Apr 94)
| 6. added support for quoted arguments (6 Jul 96)

---- --------- -------------- ------------------------------------
c1 30 Mar 92 M. Adler explode that uses huft_build from inflate
(this gives over a 70% speed improvement
over the original unimplode.c, which
decoded a bit at a time)
c2 4 Apr 92 M. Adler fixed bug for file sizes a multiple of 32k.
c3 10 Apr 92 M. Adler added a little memory tracking if DEBUG
c4 11 Apr 92 M. Adler added NOMEMCPY do kill use of memcpy()
c5 21 Apr 92 M. Adler added the WSIZE #define to allow reducing
the 32K window size for specialized
applications.
c6 31 May 92 M. Adler added typecasts to eliminate some warnings
c7 27 Jun 92 G. Roelofs added more typecasts.
c8 17 Oct 92 G. Roelofs changed ULONG/UWORD/byte to ulg/ush/uch.
c9 19 Jul 93 J. Bush added more typecasts (to return values);
made l[256] array static for Amiga.
c10 8 Oct 93 G. Roelofs added used_csize for diagnostics; added
buf and unshrink arguments to flush();
undef'd various macros at end for Turbo C;
removed NEXTBYTE macro (now in unzip.h)
and bytebuf variable (not used); changed
memset() to memzero().
c11 9 Jan 94 M. Adler fixed incorrect used_csize calculation.
c12 9 Apr 94 G. Roelofs fixed split comments on preprocessor lines
to avoid bug in Encore compiler.
c13 25 Aug 94 M. Adler fixed distance-length comment (orig c9 fix)
c14 22 Nov 95 S. Maxwell removed unnecessary "static" on auto array
c15 6 Jul 96 W. Haidinger added ulg typecasts to flush() calls.
c16 8 Feb 98 C. Spieler added ZCONST modifiers to const tables
and #ifdef DEBUG around debugging code.
c16b 25 Mar 98 C. Spieler modified DLL code for slide redirection.

/*
Explode imploded (PKZIP method 6 compressed) data. This compression
method searches for as much of the current string of bytes (up to a length
of ~320) in the previous 4K or 8K bytes. If it doesn't find any matches
(of at least length 2 or 3), it codes the next byte. Otherwise, it codes
the length of the matched string and its distance backwards from the
current position. Single bytes ("literals") are preceded by a one (a
single bit) and are either uncoded (the eight bits go directly into the
compressed stream for a total of nine bits) or Huffman coded with a
supplied literal code tree. If literals are coded, then the minimum match
length is three, otherwise it is two.
There are therefore four kinds of imploded streams: 8K search with coded
literals (min match = 3), 4K search with coded literals (min match = 3),
8K with uncoded literals (min match = 2), and 4K with uncoded literals
(min match = 2). The kind of stream is identified in two bits of a
general purpose bit flag that is outside of the compressed stream.
Distance-length pairs for matched strings are preceded by a zero bit (to
distinguish them from literals) and are always coded. The distance comes
first and is either the low six (4K) or low seven (8K) bits of the
distance (uncoded), followed by the high six bits of the distance coded.
Then the length is six bits coded (0..63 + min match length), and if the
maximum such length is coded, then it's followed by another eight bits
(uncoded) to be added to the coded length. This gives a match length
range of 2..320 or 3..321 bytes.
The literal, length, and distance codes are all represented in a slightly
compressed form themselves. What is sent are the lengths of the codes for
each value, which is sufficient to construct the codes. Each byte of the
code representation is the code length (the low four bits representing
1..16), and the number of values sequentially with that length (the high
four bits also representing 1..16). There are 256 literal code values (if
literals are coded), 64 length code values, and 64 distance code values,
in that order at the beginning of the compressed stream. Each set of code
values is preceded (redundantly) with a byte indicating how many bytes are
in the code description that follows, in the range 1..256.
The codes themselves are decoded using tables made by huft_build() from
the bit lengths. That routine and its comments are in the inflate.c
module.

History:
vers date who what
---- --------- -------------- ------------------------------------
1.0 13 Aug 92 M. Adler really simple unzip filter.
1.1 13 Aug 92 M. Adler cleaned up somewhat, give help if
stdin not redirected, warn if more
zip file entries after the first.
1.2 15 Aug 92 M. Adler added check of lengths for stored
entries, added more help.
1.3 16 Aug 92 M. Adler removed redundant #define's, added
decryption.
1.4 27 Aug 92 G. Roelofs added exit(0).
1.5 1 Sep 92 K. U. Rommel changed read/write modes for OS/2.
1.6 6 Sep 92 G. Roelofs modified to use dummy crypt.c and
crypt.h instead of -DCRYPT.
1.7 23 Sep 92 G. Roelofs changed to use DOS_OS2; included
crypt.c under MS-DOS.
1.8 9 Oct 92 M. Adler improved inflation error msgs.
1.9 17 Oct 92 G. Roelofs changed ULONG/UWORD/byte to ulg/ush/uch;
renamed inflate_entry() to inflate();
adapted to use new, in-place zdecode.
2.0 22 Oct 92 M. Adler allow filename argument, prompt for
passwords and don't echo, still allow
command-line password entry, but as an
option.
2.1 23 Oct 92 J-l. Gailly fixed crypt/store bug,
G. Roelofs removed crypt.c under MS-DOS, fixed
decryption check to compare single byte.
2.2 28 Oct 92 G. Roelofs removed declaration of key.
2.3 14 Dec 92 M. Adler replaced fseek (fails on stdin for SCO
Unix V.3.2.4). added quietflg for
inflate.c.
3.0 11 May 93 M. Adler added gzip support
3.1 9 Jul 93 K. U. Rommel fixed OS/2 pipe bug (PIPE_ERROR)

from unzip.h; nuked OUTB macro and outbuf;
replaced flush(); inlined FlushOutput();
renamed decrypt to encrypted
3.3 29 Sep 93 G. Roelofs replaced ReadByte() with NEXTBYTE macro;
revised (restored?) flush(); added FUNZIP
3.4 21 Oct 93 G. Roelofs renamed quietflg to qflag; changed outcnt,
H. Gessau second updcrc() arg and flush() arg to ulg;
added inflate_free(); added "g =" to null
getc(in) to avoid compiler warnings

/*
All funzip does is take a zipfile from stdin and decompress the
first entry to stdout. The entry has to be either deflated or
stored. If the entry is encrypted, then the decryption password
must be supplied on the command line as the first argument.
funzip needs to be linked with inflate.o and crypt.o compiled from
the unzip source. If decryption is desired, the full version of
crypt.c (and crypt.h) from zcrypt21.zip or later must be used.

#==============================================================================
# Makefile for UnZip, UnZipSFX and fUnZip: Unix and MS-DOS ("real" makes only)
# Version: 5.4 19 November 1998
#==============================================================================
# INSTRUCTIONS (such as they are):
#
# "make sunos" -- makes UnZip in current directory on a generic SunOS 4.x Sun
# "make list" -- lists all supported systems (targets)
# "make help" -- provides pointers on what targets to try if problems occur
# "make wombat" -- chokes and dies if you haven't added the specifics for your
# Wombat 68000 (or whatever) to the systems list
#
# CF are flags for the C compiler. LF are flags for the loader. LF2 are more
# flags for the loader, if they need to be at the end of the line instead of at
# the beginning (for example, some libraries). FL and FL2 are the corre-
# sponding flags for fUnZip. LOCAL_UNZIP is an environment variable that can
# be used to add default C flags to your compile without editing the Makefile
# (e.g., -DDEBUG_STRUC, or -FPi87 on PCs using Microsoft C).
#
# Some versions of make do not define the macro "$(MAKE)"; this is rare, but
# if things don't work, try using "make" instead of "$(MAKE)" in your system's
# makerule. Or try adding the following line to your .login file:
# setenv MAKE "make"
# (That never works--makes that are too stupid to define MAKE are also too
# stupid to look in the environment--but try it anyway for kicks. :-) )
#
# Memcpy and memset are provided for those systems that don't have them; they
# are in fileio.c and will be used if -DZMEM is included in CF. These days
# almost all systems have them.
#
# Be sure to test your new UnZip (and UnZipSFX and fUnZip); successful compila-
# tion does not always imply a working program.

# Makefile for UnZip, UnZipSFX and fUnZip 24 November 1998
#
# supported compilers:
# - Microsoft C, version 6.00 or higher, for use under OS/2 1.x (16-bit)
# - Watcom C/C++, version 9.0+, for use under OS/2 1.x or 2.x+ (16/32-bit)
# - emx+gcc, version 0.9c or higher, for use under OS/2 2.x+ (32-bit)
# - IBM C Set++, for use under OS/2 2.x+ (32-bit)
# - Borland C++, for use under OS/2 2.x+ (32-bit)
# - Metaware High C/C++, for use under OS/2 2.x+ (32-bit)
#
# supported cross-compilers:
# - Microsoft C, version 6.0 or 7.0, for use under DOS (16-bit)
# - Watcom C/C++, version 9.0+, for use under DOS/Win95/NT (16/32-bit)
# - GNU gcc (emx), version 0.9c or higher, for use under DOS/Win95/NT (32-bit)
#
# supported assemblers:
# - Microsoft MASM 6.00 with Microsoft C
# - Watcom WASM with Watcom C/C++
# - GNU as with GNU gcc
# To use MASM 5.x instead of MASM 6.00:
# - set AS="masm -t -Ml"
# - set ASEOL=";"
# To use, enter "{d,n}make -f os2/makefile.os2" (this makefile depends on its
# name being "makefile.os2", and it must be in the os2 subdirectory).
# Notes on Microsoft C 6.00 compilation for OS/2:
#
# The resulting programs can be used under OS/2 protected mode only, not
# under DOS. A larger stack has to be used for OS/2 because system calls
# use more stack than under DOS; 8k is recommended by Microsoft.
# Notes on IBM C Set++, Watcom C/C++, Borland C++ or emx+gcc compilation:
#
# The resulting programs can be used under protected mode of OS/2 2.x or
# higher only, not under OS/2 1.x and not under DOS.
#
# The NFLAGS macro is used to work around an optimization bug in the IBM
# C++ Set compiler; this is fixed by CSD #4, so NFLAGS="" can be used for
# all targets below.
# Notes on Watcom C/C++ compilation for DOS with the PMODE/W extender:
#
# You need to add the following section to your \watcom\binb\wlsystem.lnk
# file and also need to copy pmodew.exe to the same directory:
#
# system begin pmodew
# option osname='PMODE/W'
# libpath %WATCOM%\lib386
# libpath %WATCOM%\lib386\dos
# op stub=pmodew.exe
# format os2 le
# end
#
# PMODE/W 1.16 or higher is required. See also msdos/README for important
# notes about PMODE/W bugs.

match.c
The match() routine recursively compares a string to a "pattern" (regular
expression), returning TRUE if a match is found or FALSE if not. This
version is specifically for use with unzip.c: as did the previous match()
routines from SEA and J. Kercheval, it leaves the case (upper, lower, or
mixed) of the string alone, but converts any uppercase characters in the
pattern to lowercase if indicated by the global var pInfo->lcflag (which
is to say, string is assumed to have been converted to lowercase already,
if such was necessary).
GRR: reversed order of text, pattern in matche() (now same as match());
added ignore_case/ic flags, Case() macro.
PaulK: replaced matche() with recmatch() from Zip, modified to have an
ignore_case argument; replaced test frame with simpler one.
---------------------------------------------------------------------------

certainly written by Mark Adler...ask me how I can tell :-) ):

right notice is retained.
---------------------------------------------------------------------------
Match the pattern (wildcard) against the string (fixed):
match(string, pattern, ignore_case);
returns TRUE if string matches pattern, FALSE otherwise. In the pattern:
`*' matches any sequence of characters (zero or more)
`?' matches any single character
[SET] matches any character in the specified set,
[!SET] or [^SET] matches any character not in the specified set.
A set is composed of characters or ranges; a range looks like ``character
hyphen character'' (as in 0-9 or A-Z). [0-9a-zA-Z_] is the minimal set of
characters allowed in the [..] pattern construct. Other characters are
allowed (i.e., 8-bit characters) if your system will support them.
To suppress the special syntactic significance of any of ``[]*?!^-\'', in-
side or outside a [..] construct, and match the character exactly, precede
it with a ``\'' (backslash).
Note that "*.*" and "*." are treated specially under MS-DOS if DOSWILD is
defined. See the DOSWILD section below for an explanation. Note also
that with VMSWILD defined, '%' is used instead of '?', and sets (ranges)
are delimited by () instead of [].

Module Name:
nt.c
Abstract:
This module implements WinNT security descriptor operations for the
Win32 Info-ZIP project. Operation such as setting file security,
using/querying local and remote privileges, and queuing of operations
is performed here. The contents of this module are only relevant
when the code is running on Windows NT, and the target volume supports
persistent Acl storage.
User privileges that allow accessing certain privileged aspects of the
security descriptor (such as the Sacl) are only used if the user specified
to do so.

unshrink.c version 1.21 23 Nov 95
NOTE: This code may or may not infringe on the so-called "Welch
patent" owned by Unisys. (From reading the patent, it appears
that a pure LZW decompressor is *not* covered, but this claim has
not been tested in court, and Unisys is reported to believe other-
wise.) It is therefore the responsibility of the user to acquire
whatever license(s) may be required for legal use of this code.
THE INFO-ZIP GROUP DISCLAIMS ALL LIABILITY FOR USE OF THIS CODE
IN VIOLATION OF APPLICABLE PATENT LAW.
Shrinking is basically a dynamic LZW algorithm with allowed code sizes of
up to 13 bits; in addition, there is provision for partial clearing of
leaf nodes. PKWARE uses the special code 256 (decimal) to indicate a
change in code size or a partial clear of the code tree: 256,1 for the
former and 256,2 for the latter. [Note that partial clearing can "orphan"
nodes: the parent-to-be can be cleared before its new child is added,
but the child is added anyway (as an orphan, as though the parent still
existed). When the tree fills up to the point where the parent node is
reused, the orphan is effectively "adopted." Versions prior to 1.05 were
affected more due to greater use of pointers (to children and siblings
as well as parents).]
This replacement version of unshrink.c was written from scratch. It is
based only on the algorithms described in Mark Nelson's _The Data Compres-
sion Book_ and in Terry Welch's original paper in the June 1984 issue of
IEEE _Computer_; no existing source code, including any in Nelson's book,
was used.
Memory requirements have been reduced in this version and are now no more
than the original Sam Smith code. This is still larger than any of the
other algorithms: at a minimum, 8K+8K+16K (stack+values+parents) assuming
16-bit short ints, and this does not even include the output buffer (the
other algorithms leave the uncompressed data in the work area, typically
called slide[]). For machines with a 64KB data space this is a problem,
particularly when text conversion is required and line endings have more
than one character. UnZip's solution is to use two roughly equal halves
of outbuf for the ASCII conversion in such a case; the "unshrink" argument
to flush() signals that this is the case.
For large-memory machines, a second outbuf is allocated for translations,
but only if unshrinking and only if translations are required.
