python-veracity 0.0.9

Python wrapper for Veracity's command-line interface.

Introduction

This library provides a Python wrapper for Veracity’s command-line interface. It includes objects for repositories, working copies, and other commonly-used items. The library also installs several command-line tools to work with Veracity’s distributed build tracking features.

Note

0.0.x releases are pre-alpha; the APIs and CLIs are still being designed.

Getting Started

Requirements

• Python 2.7

• Veracity 2.5: http://veracity-scm.com

Dependencies

• sh: https://pypi.python.org/pypi/sh (subprocess wrapper for Mac/Linux)

• pbs: https://pypi.python.org/pypi/pbs (subprocess wrapper for Windows)

• virtualenv: https://pypi.python.org/pypi/virtualenv (isolated builds)

Installation

This package can be installed using pip:

pip install python-veracity

or directly from source:

python setup.py install

After installation, the package is available under the name veracity:

>>> import veracity
>>> veracity.__version__

>>> from veracity import vv
>>> vv.version()
>>> vv.repos()

Scripting Interface

A sample script might look similar to the following:

#!/usr/bin/env python

from veracity import Repository, WorkingCopy, Item

# Clone a repo
repo = Repository('veracity', remote='http://public.veracity-scm.com/repos/veracity')

# Display Repository attributes
print repo.name
print repo.users
print repo.branches
print repo.tags

# Check out a working copy (from a Repository)
work = repo.checkout("~/v/veracity")
work.delete()

# Check out a working copy (by repo name)
work = WorkingCopy("~/v/veracity", repo='veracity')
work.update(branch='master')

# Change some files
item = Item('docs/GettingStarted.txt', work=work)
item.lock()

Build Tracking

This package also installs a set of command-line tools to work with Veracity’s Build Tracking feature: http://veracity-scm.com/qa/questions/123

Configuration

In your master branch, create a setup.cfg similar to the following:

[vv-tracking]

repositories = python-veracity
series = N, C
environments = W, M, L
virtualenv = True


[vv-poller]

N_branches = *
N_command = [ $( date "+%H" ) = 00 ]
N_command-nt = if %TIME:~0,2%==00 (exit /b 0) else (exit /b 1)
N_sleep = 60 * 30
N_start = Q

C_branches = master, develop, feature-*, release-*, hotfix-*
C_sleep = 60
C_start = Q


[vv-builder]

U_enter = Q
U_path = .
U_command = make depends
U_fail = UF

B_enter = U
B_path = .
B_command = make install
B_fail = BF

T_enter = B
T_path = .
T_command = make test
T_fail = TF

C_enter = T
C_path = .
C_command = make check
C_fail = CF
C_exit = D

The series, environments, and statuses must match what is defined in your repository’s build configuration page: http://SERVER.com/repos/REPO/build-setup

Poller

To run one iteration of a poller for your repository:

vv-poller <repository names>

Or, to run forever as a daemon:

vv-poller <repository names> --daemon

From within a working copy, the poller configuration can be tested using:

vv-poller --test

Builder

To run one iteration of a builder for your repository:

vv-builder <repository names> --env <environment alias>

Or, to run forever as a daemon:

vv-builder <repository names> --env <environment alias> --daemon

From within a working copy, the builder configuration can be tested using:

vv-builder --test

Unit and Integration Tests

To run the unit and integration tests for the veracity package:

python setup.py test
