// May 20th, 1999
|

// Todd C. Wilson, Fresh Ground Software

// (todd@nopcode.com)
|
||||
// This header file will kick in settings for Visual C++ 5 and 6 that will (usually)
|
||||
// result in smaller exe's.
|
||||
// The "trick" is to tell the compiler to not pad out the function calls; this is done
|
||||
// by not using the /O1 or /O2 option - if you do, you implicitly use /Gy, which pads
|
||||
// out each and every function call. In one single 500k dll, I managed to cut out 120k
|
||||
// by this alone!
|
||||
// The other two "tricks" are telling the Linker to merge all data-type segments together
|
||||
// in the exe file. The relocation, read-only (constants) data, and code section (.text)
|
||||
// sections can almost always be merged. Each section merged can save 4k in exe space,
|
||||
// since each section is padded out to 4k chunks. This is very noticeable with smaller
|
||||
// exes, since you could have only 700 bytes of data, 300 bytes of code, 94 bytes of
|
||||
// strings - padded out, this could be 12k of runtime, for 1094 bytes of stuff! For larger
|
||||
// programs, this is less overall, but can save at least 4k.
|
||||
// Note that if you're using MFC static or some other 3rd party libs, you may get poor
|
||||
// results with merging the readonly (.rdata) section - the exe may grow larger.
|
||||
// To use this feature, define _MERGE_DATA_ in your project or before this header is used.
|
||||
// With Visual C++ 5, the program uses a file alignment of 512 bytes, which results
|
||||
// in a small exe. Under VC6, the program instead uses 4k, which is the same as the
|
||||
// section size. The reason (from what I understand) is that 4k is the chunk size of
|
||||
// the virtual memory manager, and that WinAlign (an end-user tuning tool for Win98)
|
||||
// will re-align the programs on this boundary. The problem with this is that all of
|
||||
// Microsoft's system exes and dlls are *NOT* tuned like this, and using 4k causes serious
|
||||
// exe bloat. Very noticeable for smaller programs.
|
||||
// The "trick" for this is to use the undocumented FILEALIGN linker parm to change the
|
||||
// padding from 4k to 1/2k, which results in a much smaller exe - anywhere from 20%-75%
|
||||
// depending on the size. Note that this is the same as using /OPT:NOWIN98, which *is*
|
||||
// a previously documented switch, but was left out of the docs for some reason in VC6 and
|
||||
// all of the current MSDN's - see KB:Q235956 for more information.
|
||||
// Microsoft does say that using the 4k alignment will "speed up process loading",
|
||||
// but I've been unable to notice a difference, even on my P180, with a very large (4meg) exe.
|
||||
// Please note, however, that this will probably not change the size of the COMPRESSED
|
||||
// file (either in a .zip file or in an install archive), since this 4k is all zeroes and
|
||||
// gets compressed away.
|
||||
// Also, the /ALIGN:4096 switch will "magically" do the same thing, even though this is the
|
||||
// default setting for this switch. Apparently this sets the same values as the above two
|
||||
// switches do. We do not use this in this header, since it smacks of a bug and not a feature.

||||
// Thanks to Michael Geary <Mike@Geary.com> for some additional tips!

Copyright (C) 1998-2005 Gilles Vollant
|

|
||||
This code is a modified version of crypting code in Infozip distribution
|
||||
|
||||
The encryption/decryption parts of this source code (as opposed to the
|
||||
non-echoing password parts) were originally written in Europe. The
|
||||
whole source package can be freely distributed, including from the USA.
|
||||
(Prior to January 2000, re-export from the US was a violation of US law.)
|
||||
|
||||
This encryption code is a direct transcription of the algorithm from
|
||||
Roger Schlafly, described by Phil Katz in the file appnote.txt. This
|
||||
file (appnote.txt) is distributed with the PKZIP program (even in the
|
||||
version without encryption capabilities).
|
||||
|
||||
If you don't need crypting in your application, just define symbols
|
||||
NOCRYPT and NOUNCRYPT.
|
||||
|
||||
This code support the "Traditional PKWARE Encryption".
|
||||
|
||||
The new AES encryption added on Zip format by Winzip (see the page
|
||||
http://www.winzip.com/aes_info.htm ) and PKWare PKZip 5.x Strong
|
||||
Encryption is not supported.

Decode literal, length, and distance codes and write out the resulting
|
||||
literal and match bytes until either not enough input or output is
|
||||
available, an end-of-block is encountered, or a data error is encountered.
|
||||
When large enough input and output buffers are supplied to inflate(), for
|
||||
example, a 16K input buffer and a 64K output buffer, more than 95% of the
|
||||
inflate execution time is spent in this routine.
|
||||
|
||||
Entry assumptions:
|
||||
|
||||
state->mode == LEN
|
||||
strm->avail_in >= 6
|
||||
strm->avail_out >= 258
|
||||
start >= strm->avail_out
|
||||
state->bits < 8
|
||||
|
||||
On return, state->mode is one of:
|
||||
|
||||
LEN -- ran out of enough output space or enough available input
|
||||
TYPE -- reached end of block code, inflate() to interpret next block
|
||||
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
|
||||
at length counts to determine sub-table sizes when building the
|
||||
decoding tables.

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 for LENS and DIST tables against
|
||||
the constants ENOUGH_LENS and ENOUGH_DISTS to guard against changes in
|
||||
the initial root table size constants. See the comments in inftrees.h
|
||||
for more information.

|
||||
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
|

Changes
|
||||
|
||||
Oct-2009 - Defined ZPOS64_T to fpos_t on windows and u_int64_t on linux. (might need to find a better why for this)
|
||||
Oct-2009 - Change to fseeko64, ftello64 and fopen64 so large files would work on linux.
|
||||
More if/def section may be needed to support other platforms
|
||||
Oct-2009 - Defined fxxxx64 calls to normal fopen/ftell/fseek so they would compile on windows.
|
||||
(but you should use iowin32.c for windows instead)
