[TC 11.50rc4] Compare by Content: Binary compare, Next does not always work if there's a difference in the beginning

[white]

• Go to the Total Commander program folder.
• Select TOTALCMD.EXE and TOTALCMD64.EXE.
• Execute cm_IntCompareFilesByContent.
• Click the Next difference button.
• Click the Previous difference button.
• Click the Next difference button.
  Nothing happens. You have to click it again.

This seems to only happen when there's a difference in the first line. And it only happens at the beginning, not when you alternate Next and Previous further on in the file.

11.03 acts the same way.

11.03 acts the same way.

The feature was added in Windows Commander 4.0. I tested Windows Commander 4.03 and it acts the same way..

For me, the main problem here is that Total does not indicate WHAT exactly it considered the difference.
YES, some parts of the binary representation are tinted red. BUT! there can be them in one line up to 5/7
different places, not consecutive!!! This can be called "islands" in the "sea" of solid text of 1 line, imho.
Those - according to the logic of a simple comparison, Total should demand from me press the Next difference
button up to 5/7 times? Or how is this supposed to work?

Confirmed, it happens because searching for the previous difference reaches the top of the file, setting the last found index to -1. Therefore the next click on "Next difference" actually finds the FIRST difference again. I will change it.

For me, the main problem here is that Total does not indicate WHAT exactly it considered the difference.

It's actually explained well in the help:

Next difference
Jumps to the next difference found. A continuous block of different lines will be regarded as ONE difference.

A line is considered different if there is at least one different character/byte on that line.

So, is that a bug or not?

[ghisler(Author)]

Yes it is - please try Total Commander 11.50 final!

26.12.24 Fixed: Compare by content, binary mode: clicking on Next difference, previous difference, next difference stayed on the first difference if the files started with a different line (32/64)

Tested OK using TC 11.50 32-bit and 64-bit.

It looks like in terms of the definition of the problem from the first post - it looks like this situation is now working correctly.
We can put a stamp "Fixed".
