It sounds like that may need to be adjusted. What does `git rev-parse --show-toplevel` print? It seems like the find_worktree() logic needs to be extended to handle .git files. >> The submodule was inited simply with "git submodule init" + >> "git.submodule update" Or possibly, as you mention below, it could be that "git submodule init" ended up writing the wrong core.worktree value. I'm not very familiar with how they are initialized, but the paths do seem sane, so I doesn't seem like that's the issue. If it's a problem in difftool we can probably find a way to do the right thing. It looks like the core.worktree is relative to the .git/modules/XXX directory rather than the submodule (and super-project)'s worktree. Here's our current logic: sub find_worktree { my ($repo) = @_; # Git->repository->wc_path() does not honor changes to the working # tree location made by $ENV{GIT_WORK_TREE} or the 'core.worktree' # config variable. my $worktree; my $env_worktree = $ENV{GIT_WORK_TREE}; my $core_worktree = Git::config('core.worktree'); if (defined($env_worktree) and (length($env_worktree) > 0)) { $worktree = $env_worktree; } elsif (defined($core_worktree) and (length($core_worktree) > 0)) { $worktree = $core_worktree; } else { $worktree = $repo->wc_path(); } return $worktree; } John, any thoughts? >> MAINMODULE/.gitsubmodules file contains similar entry: >> [submodule "platform/SUBMODULE"] >> path = platform/SUBMODULE >> url = ssh://git@somehost/foo/bar.git >> >> MAINMODULE/.git/config: >> [submodule "platform/SUBMODULE"] >> url = ssh://git@somehost/foo/bar.git >> >> MAINMODULE/platform/SUBMODULE/.git: >> gitdir: ../../.git/modules/platform/SUBMODULE >> >> MAINMODULE/.git/modules/platform/SUBMODULE/config: >> [core] >> repositoryformatversion = 0 >> filemode = true >> bare = false >> logallrefupdates = true >> worktree = ../../../../platform/SUBMODULE >> [remote "origin"] >> url = ssh://git@somehost/foo/bar.git >> fetch = +refs/heads/*:refs/remotes/origin/* >> >> So for me it seems that somehow the relative path inside >> MAINMODULE/.git/modules/platform/SUBMODULE/config gets configuread >> wrong during submodule init+update. >> >> I tried to update the >> MAINMODULE/.git/modules/platform/SUBMODULE/config to contain >> ../../platform/SUBMODULE as worktree path, then meld was correctly >> started, but the compare tree was not usable.

I don't really like reimplementing logic from core Git here, so I think it might be best to just call "git rev-parse --show-toplevel" here; it would also be sufficient to make sure we resolve $core_worktree against $GIT_DIR - should we be doing that for $env_worktree as well? It looks like git-rev-parse treats a relative GIT_WORK_TREE as relative to the current working directory, so we're OK there. Does anyone know why repository->wc_path() does not obey the config variable or $GIT_WORK_TREE? It seems like the most correct fix is to fix it there. ^ permalink raw reply [flat|nested] 6+ messages in thread
