* [RFC] submodule: fix handling of supermodules with relative origin URLs. [not found] <AH3Anrr6mLVedBPcgfVwy=5KRjUgdp5W8P0DQ3qaX_UjH-npDw@mail.gmail.com> @ 2012-05-18 12:13 ` Jon Seymour 2012-05-18 12:16 ` Jon Seymour 2012-05-18 19:58 ` Jens Lehmann 0 siblings, 2 replies; 4+ messages in thread From: Jon Seymour @ 2012-05-18 12:13 UTC (permalink / raw) To: git; +Cc: Jens.Lehmann, gitster, Jon Seymour Prior to this change, operations such as git submodule sync produces the wrong result when the origin URL of the super module is itself a relative URL. The issue arises because in this case, the origin URL of the supermodule needs to be prepended with a prefix that navigates from the submodule to the supermodule. This change adds that prefix.

Yeah, tests would be great (and while at it please drop the trailing '.' from the subject ;-). This version of the patch does break some existing tests, but your follow up suggests you already found that out yourself ;-) > diff --git a/git-submodule.sh b/git-submodule.sh > index 64a70d6..5008867 100755 > --- a/git-submodule.sh > +++ b/git-submodule.sh > @@ -37,7 +37,8 @@ resolve_relative_url () > remoteurl=$(git config "remote.$remote.url") || > remoteurl=$(pwd) # the repository is its own authoritative upstream > url="$1" > - remoteurl=${remoteurl%/} > + up_path="$(echo "$2" | sed "s/[^/]*/../g")" Me thinks up_path should be set in the case below, which is the only place where it is used. > + remoteurl=${remoteurl%/*} As you mentioned in your follow up this change is not correct. > sep=/ > while test -n "$url" > do > @@ -45,6 +46,9 @@ resolve_relative_url () > ../*) > url="${url#../}" > case "$remoteurl" in > + .*/*) up_path should be set here. > + remoteurl="${up_path%/}/${remoteurl%/*}" > + ;; > */*) > remoteurl="${remoteurl%/*}" > ;; > @@ -235,11 +239,24 @@ cmd_add() > usage > fi > > + # normalize path: > + # multiple //; leading ./; /./; /../; trailing / > + sm_path=$(printf '%s/\n' "$sm_path" | > + sed -e ' > + s|//*|/|g > + s|^\(\./\)*|| > + s|/\./|/|g > + :start > + s|\([^/]*\)/\.\./|| > + tstart > + s|/*$|| > + ') > + > # assure repo is absolute or relative to parent > case "$repo" in > ./*|../*) > # dereference source url relative to parent's url > - realrepo=$(resolve_relative_url "$repo") || exit > + realrepo=$(resolve_relative_url "$repo" "$sm_path") || exit > ;; > *:*|/*) > # absolute url > @@ -250,18 +267,6 @@ cmd_add() > ;; > esac > > - # normalize path: > - # multiple //; leading ./; /./; /../; trailing / > - sm_path=$(printf '%s/\n' "$sm_path" | > - sed -e ' > - s|//*|/|g > - s|^\(\./\)*|| > - s|/\./|/|g > - :start > - s|\([^/]*\)/\.\./|| > - tstart > - s|/*$|| > - ') > git ls-files --error-unmatch "$sm_path" > /dev/null 2>&1 && > die "$(eval_gettext "'\$sm_path' already exists in the index")" > > @@ -401,13 +406,14 @@ cmd_init() > if test -z "$(git config "submodule.$name.url")" > then > url=$(git config -f .gitmodules submodule."$name".url) > + sm_path=$(git config -f .gitmodules submodule."$name".path) Isn't sm_path already set correctly here?
