Git status shows entire working tree is modified immediately after git clone

I am using rocket git port on z/OS. I’ve noticed that when I clone a repository and immediately run git st, the entire working tree is “modified”. Running ‘git diff’ indicates no changes, but the subsequent git st indicates a clean working directory. See attached screenshot for details.

I thought it may be related to line-endings, but that does not seem to be the case. I have line-endings configured properly.

Can you please run the following commands in the cloned (hello_world) directory and post the results? You may edit/filter any content that you consider sensitive.

Thanks!

Thanks. Can I ask for a bit more information?

• Can you provide the content of the .gitattributes file?
• Can you run these commands in order? I want to see if the working tree is actually changing between the two invocations of git status:

     type git
     git clone git@github.ibm.com:joewmuro/hello-world.git
     cd hello-world
     ls -lTa .
     git st
     ls -lTa .
     git st

Also, does this problem occur when cloning other repos? Could you try it with either this (if you have an account on github.com with an SSH key):

 git@github.com:zorts/hello_world.git

or this:

 git clone https://github.com/zorts/hello_world.git

Note that, for the latter, you will have to set the environment variable GIT_SSL_CAINFO to point to your cacert.pem file, or else disable SSL checking (not recommended except for testing…) with:

 git config --global http.sslVerify false

– Jerry

     type git
     git clone git@github.ibm.com:joewmuro/hello-world.git
     cd hello-world
     ls -lTa .
     git st
     ls -lTa .
     git st

 git@github.com:zorts/hello_world.git

 git clone https://github.com/zorts/hello_world.git

 git config --global http.sslVerify false

Interesting, the problem does not appear when cloning the public git repo hello_world.

Here is my .gitattributes:

    JJMURO>cat .gitattributes 

    # These files are text and should be normalized (convert crlf => lf)

    *.c text
    *.h text

    # encode all files as EBCDIC unless mentioned elsewhere
    * git-encoding=iso8859-1 zos-working-tree-encoding=ibm-1047

    # encode selected files as ascii 
    .gitattributes git-encoding=ISO8859-1 zos-working-tree-encoding=iso8859-1
    .gitignore git-encoding=iso8859-1 zos-working-tree-encoding=iso8859-1

Here is output of commands:
