Program to synchronize bug repositories





bug-repo-syncer is an app to synchronize bug repositories. It currently works with Launchpad and Trac. It can in principle also be used to migrate between these repositories. The main motivation to write this program, is the lack of a Mylyn connector for Launchpad, while there exists a Mylyn connector for Trac.

The program synchronizes its own bug trackers: the project's bugs on Launchpad with a Trac site on Sourceforge.



Bug Repo Syncer is licensed under the GNU General Public License (GPL) Version 3.


The program is currently incomplete. Also the approach to translate between repositories with significantly different concepts, has inherent drawbacks.

- Bug Repo Syncer does not synchronize bug comments.
- Bug status values (status, priority, resolution, type) can only be roughly translated between repositories of different type. Bug Repo Syncer uses internally a fairly simple model, that is quite similar to the way how Trac works. When Bug Repo Syncer changes a bug, the status values are set in accordance with this simple model. This way information is lost, especially from Launchpad's fairly fine grained model.


The program is developed on Linux. It uses however nothing Linux specific, and may therefore work on other Unix-like operating systems such as Mac OS X.

The following software is required to run Bug Repo Syncer:

 An installation of the Python programming language.
 A command line program to merge text. Present on nearly all Linux and Unix installations.
 A Python library to process dates. Usually installed on Linux by default.

 A library to access launchpad from Python programs. Install it with:

 pip install launchpadlib


Open a shell window and type:

pip install bug-repo-syncer

Alternatively download the source archive, extract it, change into the extracted directory, and type the familiar:

python setup.py install


Bug Repo Syncer has the notion of a project directory, where configuration and data files are stored. For normal operation it is assumed that the user changes into the project directory and types the synchronization command(s).

Synchronization commands are executed with the bsync program, it uses sub-commands like Bazaar's bzr program.

General Options

The general options precede the sub-commands. For example, synchronize and specify the project directory explicitly:

bsync --project-dir path/to/project/dir sync

-h, --help Show a help message and exit.
--project-dir DIRECTORY
 Specify the directory with configuration and data files.

(Sub-) Commands

All subcommands have their own option --help, that shows a specific help message. To get the help message for the command sync for example, type:

bsync sync --help


Create a configuration file in the current directory. The generated configuration file must be edited, so that it refers to your bug repositories. To invoke the command type:

bsync init


Show status of project directory.

bsync info


Synchronize the repositories.

bsync sync

This sub-command has further options:
--since DATE_TIME
 Consider changes since this date (and time).

Hacking and Bug Reports

The program is written in the Python programming language. Development is coordinated on Launchpad. Bugs reports should be filed in the project's bug tracker on Launchpad. (Bugs on Trac are sometimes erroneously deleted.)
