[kmods] windows: normalize line-endings

  MSBuild XML files have to use CRLF line-endings, otherwise any change
results in the whole file being rewritten with CRLF line-endings by
Visual Studio. However, it's inconvenient to have such files checked-out
with CLRF in Unix environments.

Add suggested git configuration to top-level README, so that Unix
developers don't miss it. Remove .gitattributes, because core.autocrlf
overrides eol= attribute. Convert line-endings of the existing files in
the repository.

Doesn't the 'input' option gets you original (unmodified) line endings on checkout?
If a file in the repo has CRLF endings, Unix devs will get it as-is (with CRLF), right?
Regardless, this is the best option for Unix and since we're normalizing line endings for 
existing files, Unix devs should get LF on checkout.
I will send a patch to normalize netuio as well.

The "input" option is for Unix devs only.

AFAIK, you don't need to. Whatever you settings were when committing netuio,
it now checks out with CRLF on Windows (core.autocrlf=true, installer
default) and with LF on Linux (core.autocrlf=input, although unset also
works). I'd wait for confirmation from Luca, though.

Hi,

Thank you for looking into this. Yes the netuio folder is ok as-is:

$ dos2unix -id windows/netuio/netuio.vcxproj* windows/netuio/netuio.sln
       0  windows/netuio/netuio.vcxproj
       0  windows/netuio/netuio.vcxproj.filters
       0  windows/netuio/netuio.sln

The patch looks good to me, as I really need all files to be checked in
with LF only as a hard requirement before I can upload to
Debian/Ubuntu, so:

Acked-by: Luca Boccassi <bluca@debian.org>

Does the change also stop future check-ins of CRLF files?

It is converted to what?
You mean all files should have LF endings in the repo?

The file windows/virt2phys/virt2phys.vcxproj.filters is not converted.
And I see other stuff to fix, see below.

"use have to use" -> "have to use" ?

Isn't it automatic to have CRLF on Windows git working tree?

Isn't it the default?
If all files have LF, there is nothing to do on Unix.


I think more fixes are required as below:

Thomas pointed out that this patch still doesn't fix everything,
there's still a few CLRF around. I must have applied by mistake on a
branch where I was working on, with manual fixes, sorry for the
confusion.

Eg, with this patch applied, the diff of dos2unix is still not empty:

$ dos2unix windows/virt2phys/*
dos2unix: converting file windows/virt2phys/virt2phys.c to Unix
format...
dos2unix: converting file windows/virt2phys/virt2phys.h to Unix
format...
dos2unix: converting file windows/virt2phys/virt2phys.inf to Unix
format...
dos2unix: converting file windows/virt2phys/virt2phys.sln to Unix
format...
dos2unix: converting file windows/virt2phys/virt2phys.vcxproj to Unix
format...
dos2unix: converting file windows/virt2phys/virt2phys.vcxproj.filters
to Unix format...
$ git status
HEAD detached from origin/main
Changes not staged for commit:

Could you please send a v2 with a run of dos2unix on _all_ the files?

This is a blocker for me, I cannot upload 20.11 to Debian and Ubuntu
until I have the kmods package ready, and I cannot upload this package
until this issue is fixed.

Yes, I second that - those changes are needed too.

To clarify, having some options that convert after the fact
(clone/checkout) is _not_ a solution - everything needs to be checked
in with LF endings only, otherwise automated infrastructure (where
setting random configs it's just not an option) will break.

Yes. Regardless of core.autocrlf setting on Windows machine, where
files with CRLF are created, they're checked-in with LF and checked-out with
LF on Linux. Sorry for the late reply.
