# MultiPar
|
|
|
|
v1.3.1.5 is public
|
|
|
|
This version has some trial functions.
|
|
I fixed some problems of previous versions.
|
|
Though I tested the behavior on my PC,
|
|
there may be a bug in other environments or in a rare case.
|
|
Be careful to use this version for daily usage.
|
|
When you want a stable version,
|
|
you should not use this new one until other users try.
|
|
Unless you have a problem, v1.3.0.7 or v1.3.1.3 might be safe.
|
|
If you see a strange behavior, odd problem, or failure,
|
|
please report the incident to me.
|
|
I will fix as possible as I can.
|
|
|
|
I increased max block size from 1 GB (old versions) to 2 GB (new version).
|
|
This change is for rare case.
|
|
Normally users should not set so large block size in most case.
|
|
For compatibility, setting less than 100,000,000 bytes = 95 MB is good.
|
|
Be careful, MultiPar cannot treat too large block size properly.
|
|
When you have a set of PAR2 files with more than 2 GB block size (such like 4 GB),
|
|
par2cmdline may support them.
|
|
I adjusted some GUI components for big numbers.
|
|
If you see something bad in your language UI, please let me know.
|
|
|
|
I implemented a function to calculate MD5 hash of multiple files at verifying source files.
|
|
It seems to be faster on SSD. (I cannot test the speed by myself.)
|
|
But, it is slow on HDD.
|
|
It detects your drive type and switches function automatically.
|
|
If it fails and happens to be slow on your PC,
|
|
please report your case.
|
|
Because I don't know SSD's property so much, I will need help of users.
|
|
Thanks John L. Galt for tests and bug report on SSD.
|
|
|
|
There was a bug in v1.3.1.4, and created PAR2 files happened to contain broken packets.
|
|
MD5 hash of some packets were wrong.
|
|
When a file size was multiple of block size, the problem occurred.
|
|
Such PAR2 files are shown as damaged on MultiPar verification,
|
|
and v1.3.1.4 could not verify source files without checksum packets.
|
|
I fixed the bug in v1.3.1.5, and it can verify source files now.
|
|
Though it's possible to use such broken PAR2 files (created by v1.3.1.4),
|
|
you would better recreate new PAR2 files with this new version.
|
|
I'm sorry for the inconvenience.
|
|
Thanks nutpantz for this bug report.
|
|
|
|
When you created many PAR2 files (more than 512), verification had failed in previous versions.
|
|
I (and many users) didn't see this bug for long time.
|
|
Normally people don't create so many PAR2 files.
|
|
Thanks Martin Klefas-Stennett for finding this rare problem.
