Okay, but that check is not part of my series (it was introduced by 501770e1 "Move git-dir for submodules", which is in Git since 1.7.8), so that looks like it would need to be fixed for msysgit even without my patches, right? But I'm not so happy about the two code paths there anyway, so I prepared a patch to replace them with a single code path based upon the paths computed in the last patch of this series.

I suspect other shell scripts might be less affected when non-Windows paths are forced (at least when they aren't developed under Windows only). What about something like this: pwd() { builtin pwd -W "$@" | sed -e 's,^\([a-z]\):/,/\1/,'; } > Any other ideas? > > diff --git a/git-submodule.sh b/git-submodule.sh > index 3463d6d..f37745e 100755 > --- a/git-submodule.sh > +++ b/git-submodule.sh > @@ -139,8 +139,8 @@ module_clone() > gitdir="$gitdir/modules/$path" > > case $gitdir in > - /*) > - a="$(cd_to_toplevel && pwd)/" > + /* | [a-z]:/*) > + a="$(cd_to_toplevel && pwd -W)/" > b=$gitdir > while [ "$b" ] && [ "${a%%/*}" = "${b%%/*}" ] > do Hmm, here the path which starts with "c:/" is returned by the "git rev-parse --git-dir" which is used to initialize the $gitdir variable a few lines up. > @@ -170,8 +170,8 @@ module_clone() > > echo "gitdir: $rel_gitdir" >"$path/.git" > > - a=$(cd "$gitdir" && pwd) > - b=$(cd "$path" && pwd) > + a=$(cd "$gitdir" && pwd -W) > + b=$(cd "$path" && pwd -W) > while [ "$b" ] && [ "${a%%/*}" = "${b%%/*}" ] > do > a=${a#*/} b=${b#*/}; I don't understand why you need this. Does "pwd" sometimes return a path starting with "c:/" and sometimes "/c/" depending on what form you use when you cd into that directory? If not, does the following help you on windows? (If that is the case, you might need the pwd redefinition too to make that work) -----------------8<-------------------- diff --git a/git-submodule.sh b/git-submodule.sh index 5deabf6..5bb8109 100755 --- a/git-submodule.sh +++ b/git-submodule.sh @@ -134,7 +134,7 @@ module_clone() test -n "$name" || name="$path" base_path=$(dirname "$path") - gitdir=$(git rev-parse --git-dir) + gitdir=$(git rev-parse --git-dir | sed -e 's,^\([a-z]\):/,/\1/,') gitdir_base="$gitdir/modules/$base_path" gitdir="$gitdir/modules/$path" -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
