Re: Possible minor bug in Git




Hi Torsten,

Thank you so much for getting back to me.

Unfortunately, I believe there is a misunderstanding, as I may have
explained what I found to be a possible bug incorrectly.
The file that is originally added (and then later modified) is never
renamed or moved.
As you will see below, when a user attempts to add a file, but with
the incorrect case, the Git CLI responds the same way it would if a
file was correctly added (i.e., by displaying nothing).
However, in the above case, when you enter "git status", you find that
the file was never actually added, and remains unstaged.
A possible solution to this can be a simple error message similar to
attempting to add a file with its name misspelt.

Using your example, I have illustrated this in the text below:

    C:\Example>git init
    Initialized empty Git repository in C:/Example/.git/

    C:\Example>echo AAA > AA.txt

    C:\Example>git add AA.txt

    C:\Example>git commit -m AA.txt
    [master (root-commit) d550af0] AA.txt
     1 file changed, 1 insertion(+)
     create mode 100644 AA.txt

    C:\Example>echo BB > AA.txt

    C:\Example>git status
    On branch master
    Changes not staged for commit:
      (use "git add <file>..." to update what will be committed)
      (use "git checkout -- <file>..." to discard changes in working directory)

            modified:   AA.txt

    no changes added to commit (use "git add" and/or "git commit -a")

    C:\Example>git add Aa.txt

    C:\Example>git status
    On branch master
    Changes not staged for commit:
      (use "git add <file>..." to update what will be committed)
      (use "git checkout -- <file>..." to discard changes in working directory)

            modified:   AA.txt

    no changes added to commit (use "git add" and/or "git commit -a")

    C:\Example>git add A.txt
    fatal: pathspec 'A.txt' did not match any files

    C:\Example>git add AA.txt

    C:\Example>git status
    On branch master
    Changes to be committed:
      (use "git reset HEAD <file>..." to unstage)

            modified:   AA.txt

I am looking forward to hearing from you again.

Kind regards,
Angelo Melonas
