threading: Add factory that creates curl session for each thread. When creating a repo with an import url pointing to another repo on the same enterprise instance we call the vcssserver to check the url. The vcsserver then calls to enterprise to verify the url. This leads to two threads using the same cur session.

Developing Plugins/Extensions

An Extension or a Plugin is simply a |PY| module with a run method that expects a number of parameters, depending on which event it is listening for. To get an extension working, use the following steps:

  1. Create an extension or plugin using the below example.
  2. Save the plugin inside the :file:`/home/{user}/.rccontrol/{instance-id}/rcextensions` folder.
  3. Add a hook to the :file:`/home/{user}/.rccontrol/{instance-id}/rcextensions/__init__.py` file. For more information, see :ref:`event-listener`.
  4. Restart your |RCM| instance.

Extension example

In the following example, the run method listens for a push to a |repo| and parses the commit.

def run(*args, **kwargs):

    revs = kwargs.get('pushed_revs')
    if not revs:
        return 0

    from rhodecode.lib.utils2 import extract_mentioned_users
    from rhodecode.model.db import Repository

    repo = Repository.get_by_repo_name(kwargs['repository'])
    changesets = []
    reviewers = []

    # reviewer fields from extra_fields, users can store their custom
    # reviewers inside the extra fields to pre-define a set of people who
    # will get notifications about changesets
    field_key = kwargs.get('reviewers_extra_field')
    if field_key:
        for xfield in repo.extra_fields:
            if xfield.field_key == field_key:
                reviewers.extend(xfield.field_value.split())

    vcs_repo = repo.scm_instance_no_cache()
    for rev in kwargs['pushed_revs']:
        cs = vcs_repo.get_changeset(rev) # or get_commit. See API doc
        cs_data = cs.__json__()
        cs_data['mentions'] = extract_mentioned_users(cs_data['message'])
        cs_data['reviewers'] = reviewers
        # optionally add more logic to parse the commits, like reading extra
        # fields of repository to read managers of reviewers
        changesets.append(cs_data)

    return changesets
