Buildbot Transifex Plugin

This plugin for buildbot adds integration support with gitea, featuring push hooks, commit status updates and a change source.

Installation

pip install buildbot_gitea

This installs itself into the plugin discovery of buildbot, so no extra imports are required to get buildbot to find the plugin.

Configuration

The following configuration shows how the different parts of the plugin can be set-up in the buildbot master.cfg:

from buildbot.plugins import *

c = BuildbotMasterConfig = {}
c['www'] = {
    'change_hook_dialects': {
        'gitea': {
            'secret': '<SecretToEnterInGitea>',
            'onlyIncludePushCommit': True
        }
    },
}

c['services'] = [
    # Report status back to gitea, verbose flag enables verbose output in logging for debugging
    reporters.GiteaStatusPush(
        'https://example.com', "SECRET", verbose=True)
]

buildFactory = util.BuildFactory()

factory.addStep(steps.Gitea(
    repourl="ssh://git@example.com/example_user/example_project.git",
    mode='incremental',
    workdir="build",
    branch="master",
    codebase='example_codebase',
    progress=True,
    logEnviron=False,
))

The webhook currently supports pushes and pull requests by default, but you can subclass buildbot_gitea.webhook.GiteaHandler to add supports for other events, and then use your subclass by setting the class parameter:

# myhook.py

from buildbot_gitea.webhook import GiteaHandler
class MyGiteaHook(GiteaHandler)
    def process_whatever(self, payload, event_type, codebase):
        # This should be a list of dicts
        changes = []

        return changes

# master.cfg

from myhook import MyGiteaHook

c['www'] = {
    'change_hook_dialects': {
        'gitea': {
            'class': MyGiteaHook,
            # ...
        }
    }
}

Note that the handlers need to be named according to the scheme: process_{event} (e.g., process_create, etc).

Parameters

Change Hook

The change hook is set as part of the www section in the change_hook_dialects named gitea.

Parameter	Description
secret	The secret, which needs to be set in gitea
onlyIncludePushCommit	A push may have more than one commit associated with it. If this is true, only the newest (latest) commit of all received will be added as a change to buildbot. If this is set to false, all commits will inside the push will be added.
class	Set this if you want to use your own handler class (see above for details)

In gitea in your project or organization and add a new webhook of type gitea. Set the parameters as follows:

Parameter	Value
Target URL	https://example.com/change_hook/gitea/
HTTP Method	POST
POST Content Type	application/json
Secret	The secret from above

Change Source

The change source is part build step to clone a gitea repository. It includes features to build a pull request, if the pull request can be merged without conflicts. This needs to be used in conjunction with a gitea change_hook and have it send pull request updates in order to be able to handle pull requests.

The parameters for this are identical to the default git step from buildbot. It just uses information provided by the gitea change_hook to be able to handle pull requests.

Reporter

The reporter sets the commit status of a commit inside of gitea, so in gitea a small icon will be displayed next to the commit message, indicating the build status.

The GiteaStatusPush is added to the services section of the global master config.

The parameters are as follows:

Parameter	Value
URL	The URL to the gitea instance.
token	Generate an access token in the profile you want the buildbot to impersonate. Make sure the account in gitea has access to the repositories.
context	Renderable The context is an identifier for this status, allowing to identify from which builder this came, defaults to Interpolate('buildbot/%(prop:buildername)s')
context_pr	Renderable The context message to use, when building on a pull request, allowing to identify from which builder this came, defaults to Interpolate('buildbot/pull_request/%(prop:buildername)s')
warningAsSuccess	Treat warnings as build as success to set in the build status of gitea. If false, warnings will be displayed as warnings.
verbose	Perform verbose output

Authentication

Gitea supports OAuth2 authentication so it is possible to have buildbot communicate to Gitea to authenticate the user.

./master.cfg

from buildbot.plugins import util
c['www']['auth'] = util.GiteaAuth(
    endpoint="https://your-gitea-host",
    client_id='oauth2-client-id',
    client_secret='oauth2-client-secret')

Parameter	Value
endpoint	The URL to your Gitea app. Something like https://gitea.example.com/
client_id	The OAuth2 Client ID GUID, can be a Secret.
client_secret	The OAuth2 Client Secret provided, when creating the OAuth application in gitea. Can be a Secret.
