7-Zip 9.12 beta (Announce)

Igor Pavlov released 7-Zip 9.12 beta on 24 March 2010.

Website: http://www.7-zip.org
Download: http://sourceforge.net/projects/sevenzip/files/

Changes:

9.12 beta 2010-03-24 ------------------------- - ZIP / PPMd compression ratio was improved in Maximum and Ultra modes. - The BUG in 7-Zip 9.* beta was fixed: LZMA2 codec didn't work, if more than 10 threads were used (or more than 20 threads in some modes). 9.11 beta 2010-03-15 ------------------------- - 7-Zip now supports PPMd compression in ZIP archives. - Speed optimizations in PPMd codec. - The support for archives in installers was improved. - Some bugs were fixed. - New localization: Kazakh. 9.10 beta 2009-12-22 ------------------------- - The BUG in 7-Zip 9.09 beta was fixed: 7-Zip created incorrect ZIP archives, if ZipCrypto encryption was used.

P.S. LZMA SDK is also updated. Now the simple ANSI C 7ZDEC program also supports PPMD (compile-time option, default enabled).

7-Zip 9.13 beta | Lempel-Zip-ENOENT 2010

> 7-Zip 9.12 beta

9.13 beta is out (2010-04-15)

Changes: virtually nothing :-|

I didn't test yet, but I tested the "other compressy thing"

> Latest news
> 04 April 2010

There are many BUG's (see ^^^ shot):

1. It doesn't work - an attempt to compress "XXX.TAR" without any commandline parameters except the source name ends up in an ENOENT (1.) (not sure whether I possibly already had reported this type of BUG at some time, multiple times or even unreasonably many times in the past :confused: ...) Picked a thing called UI21DEB (2.) (no idea who had created it and why ...) and enabled the "X" hack (Why ??? WtF ...) ... hey, no ENOENT anymore, it seems to run (3.) ... but ...

2. ... not a single letter of information, no progress indicator (3.)

3. After silent exit, the compressed file seems to be there (and smaller :-) !!!), but the source file is gone (4.) !!! This is a criminal BUG, considering the file was Read-Only (5.) (IIRC some DGJPP binary of BZIP2 had the very same bug when I tested such centuries ago, maybe there are even more ...)

N/A. Well, one can decompress the file back (compressed file gets kicked again, duplicate of BUG #3) ... and the output file is intact :-)

4. Pushing CTL-C while compressing sometimes hangs

5. System requirements are not documented at all, I just tested in FreeDOS, it is undeterminable whether it is supposed to work or not (seems I even missed the infamous "Error: no DPMI get CWSDPMI"-BUG :confused: ...).

6. There are too many competing and incompatible LZMA-based attempts to replace GZIP/BZIP2: LZIP, XZ, original Igor's LZMA, new Igor's LZMA (???), original full 7-ZIP format, ...

LZMA SDK is still at 9.12, though, and (as I mentioned) now 7zdec can optionally unpack PPMD in addition to LZMA or LZMA2. This adds approx. 4k to the .EXE (for most cases). I'm pretty finished updating my compiles to 9.12 if anybody wants 'em "right now, today!" and can't wait.

I noticed that 1.10 is already out.

Yes, it needs LFNs for tempfile, that's probably a legit misfeature for the DOS port.

> 2. ... not a single letter of information, no progress indicator (3.)

The *nix philosophy seems to be "stay silent unless something goes wrong" (e.g. NASM, GCC).

That's the correct behavior. I agree it can sometimes be surprising, but it's not a huge deal. Actually, it seems to also support "-k" like Bzip2, so you may wish to use that (or set the appropriate env. var.).

http://www.nongnu.org/lzip/manual/lzip_manual.html#Invoking-Lzip

"The amount of memory required for compression is about 5 MiB plus 1 or 2 times the dictionary size limit (1 if input file size is less than dictionary size limit, else 2) plus 8 times the dictionary size really used. For decompression it is a little more than the dictionary size really used."

Dictionary seems to need 1 MB (-1) through 32 MB (-9), depending on input file size.

LZMA isn't a real file format, nor is LZMA2. 7-Zip is, but even that ignores *nix permissions, which probably is why .xz and .lz exist (both used by some GNU projects).

I may look into it some day, but I also accept patches.

That's correct.

Yes, "-k" works fine.

This time it's not tempfile, it's the final output.

That's not how R is supposed to work, and it is a big deal because loosing the input file prevents me from verifying the result, and if the result is bad I lost my data :-(

I had RTFM before and even had discovered "-k" but setting R should prevent the kickout also.

> I may look into it some day, but I also accept patches.

My time is very limited and C and C++ is a pain for me :-(

FYI, I can now rip stuff from Wista on my Pentium 1 PC with 64 MiB RAM:

There are bugs occurring with less than 64 MiB RAM only (possibly fixed in 9.15) :-)

What's new:

- Igor released another BETA
- Some BUG's fixed
- Igor indeed intends to bump version number to 15 :-)
- Test updated to desperately bloated Fire-Fox 34.0.5 (7-ZIP still beats Wing-RAR 5.20)
- System requirements are now "10 / 8 / 7 / Vista / XP / 2013 / 2008 / 2003 / 2000 / NT" ... NT 3.51 is supported, ME is NOT !!!

http://sf.net/p/sevenzip/discussion/45797/thread/9e68012c

PS: Wing-ZIP 19 is out. What's new: increased bloat to 120 MiO - can convert ZIP to PDF - can resize photos - helps to prevent islamic terrorism :-)
