v1.3.1.9 is public
|
|
|
|
This is the final release of v1.3.1 tree.
|
|
There would be no serious problem.
|
|
While I fixed some rare bugs and improved a bit, it's hard to test all possible cases.
|
|
When you see a bug, odd incident, or strange behavior, please let me know.
|
|
I will fix as possible as I can.
|
|
|
|
I tested verification of multiple source files on my new PC.
|
|
From the result, I set max number of threads for NVMe SSD to 4 threads,
|
|
when CPU has 6 or more logical cores.
|
|
This will improve speed at verifying complete source files.
|
|
(It doesn't affect for PAR files nor damaged files.)
|
|
SATA SSD : It will verify max 2 files at once.
|
|
NVMe SSD : It will verify max 3 or 4 files at once.
|
|
|
|
When many input file slices are same, their checksums become same, too.
|
|
There was a bug in my sorting function.
|
|
Nobody found the error for over than 10 years, and I solved this problem at last.
|
|
Thanks [NilEinne](https://github.com/Yutaka-Sawada/MultiPar/issues/36) for reporting the very rare incident.
|
|
|
|
When a file includes duplicated data, it's difficult to find slices in proper position.
|
|
In old versions, it might ignore overlap of slices for speed.
|
|
Then, it happend to fail finding some slices.
|
|
I implemented more complex method, and it will work well in most cases.
|
|
Thanks [swarup459](https://github.com/Yutaka-Sawada/MultiPar/issues/42) for bug report, offering samples, and many tests.
|
|
|
|
It's possible to add PAR2 recovery record to a ZIP file.
|
|
When I wrote the instructions ago, 4 GB over ZIP file was not common so much.
|
|
Because recent Windows OS supports ZIP64 format, I updated the text for compatibility.
|
|
You may read the "Add recovery record" page of MultiPar's Help documents.
|
|
Or, you may read [the article on my web-site](http://hp.vector.co.jp/authors/VA021385/record.htm).
|
|
Now, MultiPar supports large ZIP file with ZIP64 format.
|
|
Thanks [Dwaine Gonyier](https://github.com/Yutaka-Sawada/MultiPar/issues/44) for noticing the potential problem.
