[PATCH v3] remote-hg: do not fail on invalid bookmarks
Mercurial can have bookmarks pointing to nullid (the empty root revision), while Git can not have references to it. When cloning or fetching from a Mercurial repository that has such a bookmark, the import failed because git-remote-hg was not be able to create the corresponding reference. Warn the user about the invalid reference, and do not advertise these bookmarks as head refs, but otherwise continue the import. In particular, we still keep track of the fact that the remote repository has a bookmark of the given name, in case the user wants to modify that bookmark. Also add some test cases for this issue. Reported-by: Antoine Pelisse apeli...@gmail.com Signed-off-by: Max Horn m...@quendi.de --- This is a different fix than in my previous attempts. I thought a bit more about the issue, and determined that the previous fix, while working, was not really correct: It is wrong to treat nullid bookmarks as if they are non-existent; if e.g. the user wants to modify the bookmark from git, we need to into account that the remote already has a bookmark with that name. Indeed, I extended the new test cases to cover this aspect. With the previous fix, the new tests would fail upon pushing, with the new one, they work. contrib/remote-helpers/git-remote-hg | 5 ++- contrib/remote-helpers/test-hg.sh| 67 2 files changed, 71 insertions(+), 1 deletion(-) diff --git a/contrib/remote-helpers/git-remote-hg b/contrib/remote-helpers/git-remote-hg index eb89ef6..36b5261 100755 --- a/contrib/remote-helpers/git-remote-hg +++ b/contrib/remote-helpers/git-remote-hg @@ -643,7 +643,10 @@ def do_list(parser): print ? refs/heads/branches/%s % gitref(branch) for bmark in bmarks: -print ? refs/heads/%s % gitref(bmark) +if bmarks[bmark].hex() == '': +warn(Ignoring invalid bookmark '%s', bmark) +else: +print ? refs/heads/%s % gitref(bmark) for tag, node in repo.tagslist(): if tag == 'tip': diff --git a/contrib/remote-helpers/test-hg.sh b/contrib/remote-helpers/test-hg.sh index a933b1e..f5d0d97 100755 --- a/contrib/remote-helpers/test-hg.sh +++ b/contrib/remote-helpers/test-hg.sh @@ -772,4 +772,71 @@ test_expect_success 'remote double failed push' ' ) ' +test_expect_success 'clone remote with master null bookmark, then push to the bookmark' ' + test_when_finished rm -rf gitrepo* hgrepo* + + ( + hg init hgrepo + cd hgrepo + echo a a + hg add a + hg commit -m a + hg bookmark -r null master + ) + + git clone hg::hgrepo gitrepo + check gitrepo HEAD a + cd gitrepo + git checkout --quiet -b master + echo b b + git add b + git commit -m b + git push origin master +' + +test_expect_success 'clone remote with default null bookmark, then push to the bookmark' ' + test_when_finished rm -rf gitrepo* hgrepo* + + ( + hg init hgrepo + cd hgrepo + echo a a + hg add a + hg commit -m a + hg bookmark -r null -f default + ) + + git clone hg::hgrepo gitrepo + check gitrepo HEAD a + cd gitrepo + git checkout --quiet -b default + echo b b + git add b + git commit -m b + git push origin default +' + +test_expect_success 'clone remote with generic null bookmark, then push to the bookmark' ' + test_when_finished rm -rf gitrepo* hgrepo* + + ( + hg init hgrepo + cd hgrepo + echo a a + hg add a + hg commit -m a + hg bookmark -r null bmark + ) + + git clone hg::hgrepo gitrepo + check gitrepo HEAD a + cd gitrepo + git checkout --quiet -b bmark + git remote -v + echo b b + git add b + git commit -m b + git push origin bmark +' + test_done -- 1.9.0.7.ga299b13 -- To unsubscribe from this list: send the line unsubscribe git in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
