Git Failure with cat-file blob

    This fails to generate a valid file if the original file is binary but works if it is text using git 2.14.4 on z/OS.

    However when I try it on git on my Windows PC it works perfectly for both text and binary using git version 2.17.1.

    log -n 2 PDSEGEN.LOAD.XMIT
    ls-tree 35ef2077 PDSEGEN.LOAD.XMIT
    cat-file blob 089cc887490267554c7f8a572a614d4618383531 > /tmp/load.xmit

    Is this a known issue? Is there something else I need to do to make this work?

    I’m trying to access historical levels of files within the repository and this looked like a viable option until I needed access to binary files (TSO Transmit - or XMIT).

    Hi Lionel,

    Could you try to set tag for the file?
    chtag -b /tmp/load.xmit
    or
    chtag -tc IBM-1047 /tmp/load.xmit

    And then,
    cat /tmp/load.xmit

    Probably, you have EBCDIC (IBM-1047) encoded data in the file, but it is being tagged as ISO8859-1 while redirecting.

    Thanks,
    -Sergey

    That didn’t work but it was a great idea.

    Note that when I do this sequence on my Windows PC with Git version 2.17.1 that it works perfectly. I suspect something was fixed post 2.14
