Cannot push to https://foss.heptapod.net/mercurial/mercurial-devel
I'd like to push a new topic containing a tiny changeset into https://foss.heptapod.net/mercurial/mercurial-devel. However, I get a strange error:
$ hg push
pushing to ssh://hg@foss.heptapod.net/mercurial/mercurial-devel
Enter passphrase for key '/home/users/augier3pi/.ssh/id_rsa':
searching for changes
abort: push includes orphan changeset: 21197ff86cfe!
(use 'hg evolve' to get a stable history or --force to ignore warnings)
To get this, I just cloned the repo, created a topic, committed and pushed. I didn't use evolve so I don't understand why I get this.
