Bug ID: 6666
Summary: hg import rejects exported changeset in which a
directory is emptied and replaced by a symlink
Product: Mercurial
Version: 6.1
Hardware: PC
OS: Linux
Status: UNCONFIRMED
Severity: bug
Priority: wish
Component: Mercurial
Assignee: bugzi...@mercurial-scm.org
Reporter: pus...@ulukai.org
CC: mercurial-devel@mercurial-scm.org
Python Version: ---
I came across this bug while trying to fix a repo made from an svn mirror using
hg convert. I assume that the original error was made by convert. However, when
I tried to save the corrected changeset using hg export, I found that I could
not import it again using hg import. The following simple test case depicts the
error that the hg import gets in this case.
test$ hg --version
