TC7rc4 - Compare By Content, duplicate line numbers

[white]

During testing at one time I got two lines with the same line number. I know I was deleting a lot of text and undoing it, but I cannot reproduce. I want to report it anyway.

What version of TC7 was this?

What version of TC7 was this?

TC7rc3

I asked because it looked like the "writing beyond the last line in the shorter file" problem, which should be fixed in RC4.

I can now reproduce it using TC7rc4. (I changed the subject of this thread.)

Contents left file

Code: Select all

one
two
three
four
five
six
seven
eight
nine
ten

Contents right file

Code: Select all

one
two
three
four
five
six
seven
eight
nine
ten
eleven

Edit as follows.
(* Compare by content dialog, enter Edit mode)
* Place the cursor at the beginning of line 10 of the left file and hit Enter twice to insert two new lines.
* Move the cursor up two lines to get to the first inserted line.
* Press Delete to delete the first of the inserted lines.
* Go to the right file.
* Place the cursor at the end of the last line (behind "eleven").
* Hit Enter.
Now the tenth line in at the left is duplicated including the line number. See screen shot.

Thanks, I could reproduce it and fix it now! I found two reasons for the error:
1. When the line was deleted, the last line in the first file was not reset to "empty".
2. When the nw line was added, the line added to the other file wasn't set to "empty" either.

Fixing one of the two fixes the problem, but I will fix of course both.

Multiple duplicate line numbers produced using TC7rc4.1c. See screen shot. Look at line number 16 of the left file.

Can you give me again step by step instructions to create them, please? I guess that it's the same problem as above. I only fixed it tonight, _after_ sending you the new test version...

Although I could reproduce the problem regularly, I was not able to determine exactly which steps to take to get this problem. Probably because the problem was caused by multiple bugs.

I am not able to reproduce it in the last test version you sent me. So I assume this is fixed!

OK, thanks! Please contact me by e-mail if you can reproduce the problem with the latest test version.

Fixed in TC7rc5.
