Chef's kiss!

This was fast...

If I may :

True, not needed but would like to kindly ask for this myself too, and not only for source file.

Is it possible: adding filename of file 2 (not the source file) and SHA-1 as an option?

This can be discussed ofc, but i find the simplicity compared with time and size very attractive.

I hope suggestions are welcome, because, this approach was speed-wise bad ass.

 

Lol...
I could make a patch of Windows 7 (~3 GB) with Windows 95 RTM OEM as source, not really interesting btw, but:
I could do it in less than 2 min, SmartVersion would use 30 + min and I could loose ~700 MB in delta compared to SmartVersion, with almost nothing, in comparison.
Even tried to zip the Windows 7 with absolutely all i got and still 300 MB more than DumbVersion.

 

I'm not arguing that DumbVersion is fast, but with SmartVersion, there are still gains, no matter how you look at conservation using:

Code:

-nbhashbits 24 -compressratio 522

Although the winnings from a couple to tens of megabytes are not so solved in its speed.

 

I only tested with -compressratio 192
More testing should be done ofc, I hope this can evolve further, my first impression was

 

192 can be extracted on 32 bit OS

 

PM.

 

I zipped file before making a patch (to keep original date/time stamp) as an experiment.
That worked well, but, say i'm a dumb patch maker sending this patch to an equal dumb receiver without telling what extension this file should have?
Would he/she assume output file would be .exe or .7z, target size would not be helpfull info.

Code:
