PZlib (Alternative to Precomp)

[Prince4]

Can we integrate this with ISDone?

Hi Razor, news of some stable update. I was willing to use it but I always problems on decompression.

What problems?

If you problem about your Compressor GUI, like my Mini Compressor, use this if helpful:

[External compressor:pzlib]
header = 0
unpackcmd = pzlib d $$arcpackedfile$$.tmp -o $$arcdatafile$$.tmp

I do not think that's what the problem was too obvious, already I tried to decompress with both lines:

unpackcmd = pzlib d $$ arcpackedfile $$. tmp -o $$ arcdatafile $$. tmp

&

unpackcmd = pzlib -d - -o - <stdin> <stdout>

In fact out of curiosity I wanted to try your utility, the same error.

The problem is always the same, already posted ...

http://www.fileforums.com/showthread...7888&page=3#45

Using the line "unpackcmd = pzlib -d - -o - <stdin> <stdout>"

&



Using the line "unpackcmd = pzlib d $$arcpackedfile$$.tmp -o $$arcdatafile$$.tmp"

Personally I think this is one of the best compression projects developed. On my part I have much interest in the excellent level of compression, with a high speed of execution of the packing, compared to the classic precompressor.
My intention was also to integrate the MSK in the latest version, but if errors are generated during decompression of the archive created, I cannot guarantee the complete functionality.
I examine of more to see if there any file or type of files that can generate the error during decompression.

add -v option during comprssion if you have CRC errors during decompression

[External compressorzlib]
header = 0
packcmd = pzlib e - -o - <stdin> <stdout>
unpackcmd = pzlib d - -o - <stdin> <stdout>

OK I solved used PZlib v1100 (24/05/16), with this line everything works perfectly in Compr & Decomp..

[External compressor:pzlib]
header = 0
packcmd = pzlib e -v - -o - <stdin> <stdout>
unpackcmd = pzlib d - -o - <stdin> <stdout>

He tried in PES 2016, is good PZlib

I even mentioned beginning of topic, if you encounter CRC errors or just to make sure CRC stays the same, add -v

Options:
-t#: Number of threads to use (maximum = 8)
-t#p: (default = 50) Percentage of threads to use
-v: Verification so that restoration keeps CRC the same
-ai: Prints out additional information

Sorry Razor but two out of three times I get crash of the arc.exe at the beginning of compression ...

I don't understand what the problem...

[Razor12911]

It happens, freearc bug.

Tests performed on 33 different compressors, combined with various methods and masks, never any crashes with arc.exe, the thing is quite strange.

EDIT:

Probably I solved the problem lies in the line of options, run other tests of safety and I post the right configuration.

Final Test PZlib V1100 recommended options if you are experiencing app-crash in arc.exe

Comp;

[External compressor:pzlib]
header = 0
packcmd = pzlib e -v $$arcdatafile$$.tmp -o $$arcpackedfile$$.tmp

Decomp;

[External compressor:pzlib]
header = 0
unpackcmd = pzlib d - -o - <stdin> <stdout>

It's now an ordinary bug on my side, compressors with stdin and stdout during compression, and if you're compressing a large number of files, this happens. Pretty much annoying.
