repoman-scm 0.6.4

Library and tools to manage pools of code repositories

Latest Version: 0.7.1

Repoman is a python library designed to automate repository operations in release processes.

It provides a unified API to work with different SCMs, and the mechanisms to quickly have ready and clean working copies. It currently supports git and mercurial.

There are some basic concepts that are needed to start working with Repoman:

  • A Repository is an instance with the usual operations of a SCM.
  • A Depot contains a repository, and the operations to interact with Repoman managers.
  • A DepotManager provides Depots with an specific code, each DepotManager is intended to manage Depots of the same project.
  • Each Depot is locked to the task that requests it to the manager and belongs to this task till it’s freed.

But the best way to see how it works is with an example:

from repoman import depot_manager

repo_kind = 'git'
repo_url = 'https://github.com/tuenti/python-repoman.git'

manager = depot_manager.DepotManager(repo_kind=repo_kind)

depot = manager.give_me_depot('task_id', 'Owner task name')

try:
    depot.request_refresh({ repo_url: ['master'] })

    # Do work...
    depot.repository.tag('example')
    # ...

    # If you were going to continue the task in other process,
    # it needs to receive the path of the depot to request it
    depot = manager.give_me_depot_from_path(depot.path)
    assert 'example' in depot.repository.tags()

finally:
    # And when the repository is not needed anymore, free its depot
    manager.free_depot(depot, 'task_id')

You can know more by looking to the examples in the doc/examples directory, and to the full API reference.

Installation

Repoman is intended to be used as part of a more complex release automation infrastructure, it requires a quite specific set of dependencies, see Requirements section to know more about this.

To install it in your development environment, you can use pip:

pip install -e git+https://github.com/tuenti/python-repoman.git@v0.6#egg=repoman

To install it in your production environment, it’s recommended to generate your own packages, usual tools can be used for that, e.g:

python setup.py bdist_egg

Requirements

Repoman should play well with any Linux distribution with Python > 2.6, it’s daily used in Debian, and has been also tested in Ubuntu and Fedora.

As a general rule, pip install -r requirements.txt is able to install everything, but some things need to be taken into account.

pygit2 needs to be compiled, for that you need a gcc toolchain and the development files of libgit2 (see pygit2 installation notes). You have to use the same version of pygit2 and libgit2. Currently repoman only works with 0.20 series. It’s recommended to prepare your own set of pre-built packages for your production enviroment.

mercurial > 2.1 is also required, as well as python-hglib, the version specified in the requirements.txt file should be fine.

Some Dockerfiles are provided in the docker directory that can serve as examples about how to prepare an environment to work with repoman in different distributions.
