Hi Isis, thanks for your answer.

Yes, Lunar showed me this page, and we used it when he gave me a summary
of what each of the projects do.

I'm not familiar yet with the process to maintain *.tpo services, and
what part is done by sysadmin team, and what part can be done by
maintainer of a service, like installing dependencies or other operations
that require root access. Do you (or someone else reading this) have more
details about this ?

An idea could be to have a Debian package for bridgedb, and make Jenkins
update the packages in a repository automatically when there are new
We could have the following package repositories :
- bridgedb-common-wheezy: backports of dependencies required to run
bridgedb on wheezy
- bridgedb-master-wheezy: packages produced from master (or
development) branch on wheezy
- bridgedb-stable-wheezy: packages produced from stable branch on
- bridgedb-xxxx-wheezy: packages from xxxx branch, if needed
When you push a new commit, Jenkins rebuilds the package and moves it to a
temporary repository. Then it starts a new container or VM with that
repository enabled, install the bridgedb package and run some tests. If
the tests succeed, the package is moved to the repository corresponding
to the branch.
When you think that what is in the master branch is ready to be used,
you merge it to the stable branch, wait for Jenkins to rebuild the
packages then run apt-get upgrade on the server where bridgedb is
running. You can also setup a second server that is used as a staging
environment, with the master branch packages repository.
It might be possible to do something similar using pip and virtualenv.
However if it can be done using Debian packages, it will be easier as
the process to update and test Debian packages can be shared with the
other projects that are not in python.

Ok, so the tests should be run from the installed version. This looks

If we use Debian packages as described above, then we don't need
virtualenv, but we need some Debian packaging.

The https://para.noid.cat/bridgedb/ documentation ?
I don't know if there is already some place for such documentation.
Maybe that could be something like http://doc.torproject.org/bridgedb/,
and we can have it updated by Jenkins automatically when there are new
