git auto convert file from CRLF to LF not working

Question

On our system, we used to be able to convert all CRLF to LF while committing file into git. Now this feature is gone.

Here is what I've done:

git config --global core.autocrlf false

After doing the above, I use the following command to check:

git config --list

The result is:

... 
core.autocrlf=input
...
core.autocrlf=false
...

It's very puzzling. While there's two entries of core.autocrlf, and the first one is core.autocrlf=input? If I unset core.autocrlf using:

git config --global --unset core.autocrlf

I still get one entry when I list git config:

core.autocrlf=input

Step 2: After I did git config --global core.autocrlf false, I add * text=auto into .gitattributes file.

But git still does not automatically convert line break for me.

Answer 1

Since git1.8.1rc1 :

"git config --get" used to diagnose presence of multiple definitions of the same variable in the same configuration file as an error, but it now applies the "last one wins" rule used by the internal configuration logic

So your second setting apply.

For more explaination on option for core.autoctrlf :

If you’re on a Windows machine, set it to true – this converts LF endings into CRLF when you check out code:

$ git config --global core.autocrlf true

You can tell Git to convert CRLF to LF on commit but not the other way around by setting core.autocrlf to input:

$ git config --global core.autocrlf input

If you’re a Windows programmer doing a Windows-only project, then you can turn off this functionality, recording the carriage returns in the repository by setting the config value to false:

$ git config --global core.autocrlf false
