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, Dscho

       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.

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)

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...").
