Package: mercurial-server
Version: 1.2-2.2
Severity: grave
Justification: renders package unusable
Dear Maintainer,
after upgrading my mercurial server from stretch to buster, I'm not
able to push or clone to this server from a buster client, the command
fails with:
...
remote: File
"/usr/share/mercurial-server/mercurialserver/changes.py", line 6, in changes
remote: start = repo.changectx(node).rev()
remote: AttributeError:
'derivedrepo:/var/lib/mercurial-server/repos/projec' object has no
attribute 'changectx'
abort: stream ended unexpectedly (got 0 bytes, expected 4)
Only solution found is to disable access hook in
/etc/mercurial-server/remote-hgrc.d/access.rc but since it's removing
all access control security, this is not a real solution (and it also
raises another bug in the logging hook but at least repository is
cloned/pushed).
Clone from or pull are not affected (except for the logging hook bug).
Steps to reproduce:
sudo lxc-create hgserver -t debian --
--package=mercurial-server,openssh-server,sudo,reportbug -r buster
sudo lxc-start hgserver
sudo lxc-attach hgserver
apt update
apt dist-upgrade
cd
ssh-keygen
mkdir -p /etc/mercurial-server/keys/root
cp .ssh/id_rsa.pub /etc/mercurial-server/keys/root
sed -i 's/localhost/localhost hgserver/' /etc/hosts
sudo -u hg /usr/share/mercurial-server/refresh-auth
mkdir project
cd project
hg init
touch spam
hg add spam
hg commit -m 'add spam' -u root
hg clone . ssh://hg@127.0.0.1/project
