Installation

There are several ways for installing Perceval on your system: from packages, from a docker image or from the source code.

Pip

Perceval can be installed using pip, a tool for installing Python packages. To do it, run the next command:

$ pip3 install perceval

Docker

A Perceval Docker image is available at DockerHub.

Detailed information on how to run and/or build this image can be found here.

Source code

To install from the source code you will need to clone the repository first:

$ git clone https://github.com/chaoss/grimoirelab-perceval.git

In this case, setuptools package will be required. Make sure it is installed before running the next commands:

$ pip3 install -r requirements.txt
$ python3 setup.py install

Documentation

Documentation is generated automagically in the ReadTheDocs Perceval site.

Examples

Askbot

$ perceval askbot 'http://askbot.org/' --from-date '2016-01-01'

Bugzilla

To fetch bugs from Bugzilla, you have two options:

a) Use the traditional backend

$ perceval bugzilla 'https://bugzilla.redhat.com/' --backend-user user --backend-password pass --from-date '2016-01-01'

b) Use the REST API backend for Buzilla 5.0 (or higher) servers. We strongly recommend this backend when data is fetched from version servers >=5.0 because the retrieval process is much faster.

$ perceval bugzillarest 'https://bugzilla.mozilla.org/' --backend-user user --backend-password pass --from-date '2016-01-01'

Confluence

$ perceval confluence 'https://wiki.opnfv.org/' --from-date '2016-01-01'

Discourse

$ perceval discourse 'https://foro.mozilla-hispano.org/' --from-date '2016-01-01'

Docker Hub

$ perceval dockerhub grimoirelab perceval

Gerrit

To run gerrit, you will need an authorized SSH private key:

$ eval `ssh-agent -s`
$ ssh-add ~/.ssh/id_rsa
Identity added: /home/user/.ssh/id_rsa (/home/user/.ssh/id_rsa)

To run the backend, execute the next command:

$ perceval gerrit --user user 'review.openstack.org' --from-date '2016-01-01'

Git

To run this backend execute the next command. Take into account that to run this backend Git program has to be installed on your system.

$ perceval git 'https://github.com/chaoss/grimoirelab-perceval.git' --from-date '2016-01-01'

Git backend can also work with a Git log file as input. We recommend to use the next command to get the most complete log file.

git log --raw --numstat --pretty=fuller --decorate=full --parents --reverse --topo-order -M -C -c --remotes=origin --all > /tmp/gitlog.log

Then, to run the backend, just execute any of the next commands:

$ perceval git --git-log '/tmp/gitlog.log' 'file:///myrepo.git'

or

$ perceval git '/tmp/gitlog.log'

Running tests

Perceval comes with a comprehensive list of unit tests. To run them, in addition to the dependencies installed with Perceval, you need version 0.8.6 of httpretty. Currently, latest version in pypi is 0.8.14, which seems to have a bug exposed by some Perceval tests. So, ensure you install 0.8.6, which is known to work with them:

$ pip install httpretty==0.8.6
$ cd tests
$ python3 run_tests.py
