problem using git on cygwin

Hi,

 Am completely new to git, and following from the tutorial, to use git
for my project.

 Using git version 1.5.0.3 on cygwin (available on packages).

I am able to do the steps.
1. git init on my source
2. git add .
3. git commit

After that, a new file is created for the project and after editing the file.
am trying to put into the souce.

since it is a new file for my project git repository, am trying to add it
but end up with errors as follows.


$ git add project/test.c
error: bad index file sha1 signature
fatal: index file corrupt

could you please help me, what am doing wrong?


best regards,
srinivas.

I could imagine that you do not have "binary mode" default for opening 
files.

However, if you do, maybe your .git/index went corrupt?

As a workaround, you could try "git read-tree HEAD" and then "git add" 
again, but make sure you have a backup of .git/index, since it could be a 
bug in Git(cygwin) and if so, I'd like to fix it.

Ciao,

       i do't think it is in binary mode when opening the files. I am
used vim to create a new file and editing through that. And also am
used file format (set ff=unix).

     I have taken the initial index (once repository created, after
initial commit) to backup.
and followed the above steps.

1. cp index index.orig
2. git read-tree HEAD
3. git add test.c (my new file)

But end up with the same errors. Would you think there is a bug in the
git working on cygwin ?. I hope would the sequence help you in
catching the bug.

Johannes was referring to binary mode for writing files for _cygwin_
itself, not for files the git has to manage. See "Default Text File Type"
in cygwins setup.exe (maybe even follow the link "Read more...").

I think Johannes meant Cygwn filesystem mount attributes. Please run

    $ mount

And you should see "binmode". Here are examples:

    D:\cygwin on / type system (binmode)
    D:\cygwin\bin on /usr/bin type system (binmode)
    D:\cygwin\lib on /usr/lib type system (binmode)
    E:\data\src on /usr/src type system (binmode)

If not, you need to remount directories with "-b" option. See man
mount(1)
