BzrSync - Bazaar repository/branch synchronization tool
=======================================================
BzrSync is a tool to help a developer using Bazaar on multiple machines.
It automatically keeps selected repositories and branches synchronized across
the machines. Bazaar itself is used for the synchronization (with "bzr pull"),
ensuring consistency at all times.
Features
--------
- any number of machines are supported
- consistency is guaranteed at all times
Installation
------------
To install the latest stable version of BzrSync, using pip_:
::
pip install bzrsync
or using setuptools_:
::
easy_install bzrsync
Otherwise, if neither pip_ nor setuptools_ are available, it is possible
to download (eg. from PyPI_) the `source`_ package, extract it and run the
usual ``setup.py`` commands:
::
python setup.py install
.. _pip: http://pypi.python.org/pypi/pip
.. _setuptools: http://pypi.python.org/pypi/setuptools
.. _EasyInstall: http://peak.telecommunity.com/DevCenter/EasyInstall
.. _PyPI: http://pypi.python.org/pypi
.. _`source`: http://pypi.python.org/pypi/bzrsync
Usage
-----
Let's suppose you work from three different workstations, and their hostnames
are `alpha`, `beta` and `gamma`. You want to keep your Bazaar repositories and
branches synchronized between all three nodes using BzrSync.
BzrSync is meant to be used with shared repositories, so if you are not
using these, you should re-organize your branches to use shared repositories.
It's easier to keep all the repositories inside the same directory.
In our example our repositories will reside in ~/bzr and their names will
end in ".bzr".
In each shared repository, at the top level there should be a directory for
each node. In our case `alpha`, `beta` and `gamma`.
For example, let's imagine we have a repository named "project-foo.bzr".
We are working on `alpha`, and have created a `trunk` and a `feature-1` branch.
We'll have:
::
~/bzr/project-foo.bzr/
~/bzr/project-foo.bzr/alpha
~/bzr/project-foo.bzr/alpha/trunk
~/bzr/project-foo.bzr/alpha/feature-1
~/bzr/project-foo.bzr/beta
~/bzr/project-foo.bzr/gamma
Let's suppose we also have a `local.bzr` repository we don't want to
synchronize, in either direction.
BzrSync needs a YAML config file, by default `~/.bazaar/bzrsync.yaml`,
listing the repositories and the branches we.
In this example its contents will be:
::
# remote nodes
# (a host can be specified with an optional port as HOST:PORT)
hosts:
- alpha
- beta
- gamma
# where repositories specified with a relative path/pattern are located
root: ~/bzr
# *all* repositories
repositories: "*.bzr"
# specific repositories to exclude from 'repositories'
exclude:
- local.bzr
# repositories to export to remote nodes
export: "*.bzr"
# specific repositories excluded from export
export_exclude:
- local.bzr
# repositories to sync from remotes
sync: "*.bzr"
# specific repositories excluded from sync
sync_exclude:
- local.bzr
We can use exactly this same configuration file on all three nodes.
BzrSync won't create the shared repositories for you, so before proceeding,
do so now on all the nodes, remembering to create also the node
subdirectories.
Then launch the BzrSync daemon on all the nodes:
::
alpha$ bzrsync serve
beta$ bzrsync serve
gamma$ bzrsync serve
Now let's sync project-foo.bzr from alpha to beta:
beta$ bzrsync sync ~/bzr/project-foo.bzr
This will pull to `beta` all the branches from `~/bzr/project-foo.bzr/alpha/`
on `alpha`, and all the branches from `~/bzr/project-foo.bzr/gamma/`
on `gamma`.
In our case, only alpha has branches right now, so in practice we'll
get the branches `alpha/trunk` and `alpha/feature-1` from `alpha` to
`beta`, keeping them as `alpha/trunk` and `alpha/feature-1`.
If you want to work on `beta`, now branch from the newly synchronized branches
to their counterparts inside the `beta/` subdirectory:
::
beta$ bzr branch ~/bzr/project-foo.bzr/alpha/feature-1 ~/bzr/project-foo.bzr/beta/feature-1
beta$ bzr co ~/bzr/project-foo.bzr/beta/feature-1 foo-feature-1
beta$ cd foo-feature-1
...
hack hack hack
...
beta$ commit
Now on `beta` we'll have:
::
~/bzr/project-foo.bzr/
~/bzr/project-foo.bzr/alpha
~/bzr/project-foo.bzr/alpha/trunk
~/bzr/project-foo.bzr/alpha/feature-1
~/bzr/project-foo.bzr/beta
~/bzr/project-foo.bzr/beta/feature-1
~/bzr/project-foo.bzr/gamma
When you have finished working on beta, you can sync from alpha:
alpha$ bzrsync sync ~/bzr/project-foo.bzr
and this will create `beta/feature-1` on `alpha` too, which you can
pull onto `alpha/feature-1` if not diverged, or merge it otherwise,
and start working from `alpha` again.
Please see the example `bzrsync.yaml` file for a more complete example, which
includes also branch sets.
Help and Development
--------------------
Alternatively, if you'd like to update the software occasionally to pick
up the latest bug fixes and enhancements before they make it into an
offical release, branch from the `Bazaar`_ repository hosted on `LaunchPad`_
instead.
Just follow the procedure outlined below:
1. Make sure that you have `Bazaar`_ installed, and that you can run its
commands from a shell. (Enter ``bzr help`` at a shell prompt to test
this.)
2. Create a local branch and working tree from the official one::
bzr branch lp:bzrsync bzrsync
3. Then from the ``bzrsync`` directory you can run the ``setup.py develop``
command to install the library in your Python `site-packages` directory
using a link, which allows to continue developing inside the working tree
without the need to re-install after every change. See the
`setuptools development mode`_ documention for more information::
