- v0.43 *
-
Added Visual Basic 6 wrapper, thx to Jon Johnson!
Added PowerBuilder 9.0 objects, thx to James Sheekey!
Fixed a rare crash, thx to cyberbob!
- v0.42 *
-
Added C and assembler implementations of a new safe depacker
(aP_depack_safe and
aP_depack_asm_safe).
Updated the aPsafe_
wrapper functions.
Renamed lib/vc
to lib/mscoff
and
lib/watcom
to lib/omf
to better reflect that
they are not limited to those specific compilers.
Updated examples and documentation.
- v0.41
-
Added a Borland C++ Builder
example, thx to mouser!
Fixed vc library compatibility with
Pelles C.
- v0.40
-
The documentation was rewritten in html, and moved to a separate
folder.
All examples were updated. The dll_asm
, dos32
and tlink32
examples were removed, and a small .NET example
was added.
- v0.39
-
All aPLib functions now return -1
on error instead of
0
. Added a macro APLIB_ERROR
for this value to
all include files.
- v0.38
-
The aPLib compression functions should now be fully thread-safe.
Updated the C decompression code for thread-safety.
- v0.37
-
Changed the parameters for the callback function. It is now called
with the input size, input bytes processed, output bytes produced,
and a user-supplied callback parameter. Thx to f0dder!
- v0.36 *
-
Fixed a bug which could cause a match to be found in the area
before the input buffer under certain conditions, thx to Veit!
Changed the extension of the C example files from cpp to
c.
The ELF32 version was tested under FreeBSD, thx to Oleg!
- v0.35
-
Worked with a number of 'issues' in the build process.
Fixed the C depacker so it no longer modifies the input buffer,
thx to Trevor Mensah!
- v0.34 *
-
Updated the 16bit, Ada, Delphi, C/C++, TMT Pascal and Virtual
Pascal examples, thx to METALBRAIN, Gautier, Oleg and Veit!
Added a MASM32 example program, thx to Steve Hutchesson!
Fixed another bug which could cause aP_pack to read one byte
past the input buffer, thx to Reiner Proels!
NOTE!! the dll version now expects the callback function to
use the stdcall calling convention.
The libraries now include the function aP_max_packed_size,
which given the input size returns the maximum possible size
aP_pack may produce (i.e. the worst case output size of totally
incompressible data). At the moment the function simply returns
(inputsize + (inputsize / 8) + 64)
.
- v0.33
-
Added ELF32 version of aPLib, which has been tested with Linux,
BeOS and QNX. Modified the C example to work under these
operating systems too.
- v0.32
-
Discovered some mixups between different versions of the
examples .. started rewriting some of them. Added a header
to the files created by most of the examples.
- v0.31
Improved compression ratio a little.
- v0.30
-
Fixed a bug in one of the 16bit depackers, thx to Peter Hegel!
Updated the C/C++ example.
- v0.29
-
Updated the Ada example, thx to Gautier! I have removed the 'b'
from the version number.
- v0.28b
-
Updated the 16bit depacker examples, thx to METALBRAIN!
Renamed the SRC/C depacker files.
- v0.27b
-
Fixed a bug which could cause aP_pack to read one byte past
the input buffer.
- v0.26b *
-
Added Visual C++ and Borland C examples.
Rewrote the example program, so there is only a single source file,
which works with BCC32, DJGPP, VC++ and Watcom.
Added an import library for Visual C++ in lib/dll, and
an example of how to use it (examples/c/make_dll.bat).
The libraries now include the function aP_workmem_size,
which given the input size returns the amount of memory
required for the work buffer (you still have to allocate
it yourself). This should make upgrading easier in case
I change the memory requirement in a later version. At
the moment the function simply returns 640k.
- v0.25b
-
Added a TMT Pascal example, thx to Oleg Prokhorov!
Moved the Ada and VPascal examples to the example dir.
Updated the documentation.
- v0.24b
-
Updated the 16bit depacker examples, thx to METALBRAIN!
Made all assembler depackers smaller, thx to TAD and METALBRAIN!
- v0.23b
-
Recompiled with the latest VC++ and DJGPP versions.
Did a few speed optimisations -- most versions should be a
little faster.
- v0.22b *
-
Improved the compression speed a little more.
Cleaned up the code, which made the library somewhat smaller.
Added a C depacker.
Silent update: Updated the 16bit depackers - thx to
METALBRAIN. There is still one problem with the 16bit
example depackers, but it will be fixed for the next
release.
- v0.21b
-
Improved compression ratio and speed.
Added Ada support by Gautier - thx!
Reduced the memory requirement from 1mb to 640k -- which should
be enough for anybody ;).
- v0.20b *
-
Added Delphi support and example by Alexey Solodovnikov - thx!
Rewrote the aPPack example, removing some errors, and
added 16bit depackers - thx to METALBRAIN!
Removed a lot of unneeded information from the object files.
Rearranged all the folders -- hope it's not too
confusing ;). Removed all the example binaries from this
file, and made them available in a separate file instead.
Added the real aPACK / aPLib homepage URL, since home.ml.org
was down for a period.
- v0.19b *
-
Fixed a little mem bug (hopefully), thx to ANAKiN!
Ratio improved a little on large files.
Finally got around to updating my DJGPP installation :)
NOTE!! I have revised the license conditions -- please
read APLIB.DOC.
- v0.18b *
-
Added the new VPascal interfacing code by Veit Kannegieser.
Added a library compiled for VC.
Worked a little on the depackers.
- v0.17b *
-
NOTE!! the callback function now has to return a value.
This is to make it possible for the callback function to
abort the packing without exiting the program. If the
callback returns 1, aP_pack will continue -- if it returns
0, aP_pack will stop and return 0.
The aPACK / aPLib homepage is now up on: http://apack.home.ml.org/
I have not gotten the new VPascal interfacing code from
Veit yet, so I will add it again in the next version :)
Since I have added so much new stuff, I am releasing this
version to get some feedback (hint!), to find out where
to go from here. If you have Visual C++, Borland C++,
Borland C++ Builder, Visual Basic, Delphi or other 32-bit
compilers/linkers, I am very interested in any problems
you might have using aPLib (especially the DLL version).
- v0.16b
-
NOTE!! aP_pack NO LONGER allocates the memory it needs
itself. This was changed because otherwise you would
need to supply malloc and free functions to the packer.
Now you just call aP_pack with a pointer to 1mb of mem.
This is also faster if you compress multiple sets of data,
because mem is not allocated and deallocated every time.
Added new VPascal interfacing code by Veit Kannegieser - thx!
Added DOS32 and TLINK32 (Win32 PE) example code and executables.
Also added a DLL version of aPLib, and some
example code for it. By the way -- the DLL version works fine as a wdl
file for WDOSX!
Speeded up the fast depackers a tiny bit.
- v0.15b
-
Quite a few people have pointed out to me that AR was not
the cleverest library format to use, so I changed to OMF
format, which works with (at least) Watcom, DOS32 and
TASM32/TLINK32.
Added assembler depackers for TASM and WASM, and added the fast
assembler depacker for NASM.
The Watcom and DJGPP libraries now also contain compiled
versions of aP_depack_asm and aP_depack_asm_fast, and the
APDEPACK.H files with the inline assembler versions have
been removed.
- v0.14b *
-
Made some minor enhancements to the packer - ratio is a
little better.
Added depacking code for NASM, converted by Archee/CoNTRACT - thx!
- v0.13b
-
Added depacking code for Pascal (Virtual Pascal), converted
by Veit Kannegieser - thx!
Switched to AR format for the Watcom library.
- v0.12b *
Changed the libraries to make them C-compatible.
- v0.11b
aP_depack_asm_fast is a little faster.
- v0.10b *
Compression is a little faster :)
- v0.09b
Compression is a little better :)
- v0.08b *
First release version of aPLib :)
- v0.07b
-
Fixed a bug that gave errors when compressing multiple sets of
data (thx x-otic!). Cleaned up the code a little.
- v0.06b
-
Changed the packer, so it uses a fixed amount of mem (about 1 meg).
A few bugs fixed.
- v0.05b
First version of the aPLib library included.
- v0.04b
Added the DJGPP fast asm unpacker.
- v0.03b
Optimised the depacker a little.
- v0.02b
Second try ;-P
- v0.01b
First try!
Project started March 5th 1998.
