In sum() new hasher whirlpool

zpaqfranz sum * -whirlpool

Exposed zfs commands

• zfslist => list existing snapshots
• zfspurge => delete snapshot
• zfsadd => freeze into a zpaq archive many snapshot at once

zpaqfranz -h zfs
zpaqfranz zfslist "*" "*"
zaqpfranz zfsadd "/tmp/47/zpaqfranz" "/temporaneo/kongo7.zpaq"  "tank/d@2021" "--7d"
zfspurge "tank" "--7d"

When adding files it is now possible to use -blake3 as a file integrity checker

zpaqfranz a z:\1.zpaq c:\nz -blake3

...
zpaqfranz t z:\1.zpaq -verify

Just for fun in the b (benchmark) now the
-all (multithread)
-tX (when used with -all limit to X thread. Note NO SPACE)

Beware: high CPU load brings high temperature, watch your cooler!

Benchmark all:                       b
Benchmark all on 1.86GB:             b -minsize 2000000000
Benchmark all on 1MB:                b -minsize 1048576
Benchmark SHA256 and BLAKE3:         b -sha256 -blake 3 -minsize 1048576
Benchmark for 10 second each:        b -n 10 -sha256 -blake3 -minsize 1048576
Cook the CPU (all cores):            b -all -n 20 -blake3
Cook the CPU (8 cores):              b -all -t8 -n 20 -blake3

Very rough benchmark command for hashes-checksums test.
By default runs 5 seconds each on 390.62 (-7) KB
To be developed in future (in fact it is a BLAKE3 mock up test)

zpaqfranz b

A slightly faster SHA 256 in file hashing
Two time faster SHA 1 in file hashing in multithread (!)
Experimental -wyhash with memory mapped file (just for fun)
Various minor fix

Windows 32/64 binary

I found a bug in gcc 10.3 (default for latest Ubuntu 21)
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=101558
so I try a workaroud (I hope that everything will runs fine!)

Then another strange behavior of some Linux gcc compiler (!), that do strange things with 64-byte aligned data.
Therefore I made a massive rework of XXH3 interface.
Now the default hasher is XXHASH64, as the -128 (or -xxh3) needs more test.

So yes, even the compiler can broke your valuable software!

Now
-xxhash = XXHASH64: new default
-xxh3 = XXH3 (XXHASH 128 bit)

Experimental -wyhash (just a test)

Windows 32/64 binary

New switch -filelist
zpaqfranz a z:\1.zpaq c:\nz -filelist
zpaqfranz x z:\1.zpaq -filelist

New behavior: store by default XXH3 and CRC-32 of every file (to be completed)

New switches -checksum and -summary in list

zpaqfranz l z:\1.zpaq -checksum (show CRC and hash if any)
zpaqfranz l z:\1.zpaq -checksum -summary (compact output)
