[Xen-devel] scripts/git-checkout.sh fails in some cases

[Fabio Fantoni <fabio.fantoni@xxxxxxx>]

I already saw scripts/git-checkout.sh fails many times changing repo 
and/or tag for my tests, for example today:
> GIT=git 
> /mnt/vm/source/xen/Xen/tools/firmware/../../scripts/git-checkout.sh 
> git://xenbits.xen.org/osstest/ovmf.git xen-tested-master ovmf-dir

I not understand why use a dummy branch even if directory is a "temp."
I tried a very fast change and worked:
> #!/bin/sh
>
> if test $# -lt 3; then
>         echo "Usage: $0 <tree> <tag> <dir>"
>         exit 1
> fi
>
> TREE=$1
> TAG=$2
> DIR=$3
>
> set -e
>
> if test \! -d $DIR-remote; then
>         rm -rf $DIR-remote $DIR-remote.tmp
>         mkdir -p $DIR-remote.tmp; rmdir $DIR-remote.tmp
>         if test "$TAG" ; then
>                 $GIT clone -b $TAG $TREE $DIR-remote.tmp
>         else
>                 $GIT clone $TREE $DIR-remote.tmp
>         fi
>         mv $DIR-remote.tmp $DIR-remote
> fi
> rm -f $DIR
> ln -sf $DIR-remote $DIR
But probably a better improvement/solution is needed for a good script 
working with any branch (its head) or tag.
Thanks for any reply and sorry for my bad english.
