Package: buildbot
Version: 2.10.1-1
Severity: important
Hello,
Our buildbot instances has the web interface enabled:
c['www'] = dict(port=8080)
But buildbot doesn't want to start:

2022-01-24 20:37:17+0100 [-] adding 441 new schedulers, removing 0
2022-01-24 20:37:34+0100 [-] while starting BuildMaster

raise RuntimeError("could not find buildbot-www; is it installed?
%s" % (str(info())))
The str(info()) part is an addition on our side to know what plugins
were actually detected, and we have: [...] 'www': {}}
so nothing is detected for www. Indeed, looking at the source code in
/usr/lib/python3/dist-packages/buildbot/plugins/db.py that detects
plugins:
def _tree(self):
if self._real_tree is None:
self._real_tree = _NSNode()
for entry in iter_entry_points(self._group):
This is using pkg_resources.iter_entry_points to get the list of python
classes etc. but that reports nothing, for instance in a plain chroot:
# apt install buildbot
# python3 -c "import pkg_resources ;
print(list(pkg_resources.iter_entry_points('buildbot.www')))"
[]
while /usr/lib/python3/dist-packages/buildbot/www/ is really there. One
thing I noticed is that
/usr/lib/python3/dist-packages/buildbot-2.0.1.post2.egg-info/entry_points.txt
doesn't list anything for buildbot-www.
We had to revert to the manual installation of buildbot, the Debian
package was unusable for us.

Linux, c'est simple : ça s'adresse à une machine qui est parfois un peu
maraboutée mais qui d'habitude n'a pas d'états d'âme. Sur Usenet y'a
plein d'humains et de primates, et ça devient vraiment gore par moment.
