trac-bitbucketsync

This modified BitbucketSyncPlugin syncs Bitbucket/Gitlab repository with local Git repository used by Trac.

See https://trac-hacks.org/wiki/BitbucketSyncPlugin for more info.

Installation

Install mercurial dependency and the trac-bitbucketsync plugin using easy_install:

easy_install mercurial
easy_install https://github.com/phuc77/trac-bitbucketsync/zipball/master

Bitbucket Webhooks

Open your repository on bitbucket.org and go to Settings -> Webhooks and click on Add webhook and use as URL:

https://example.com/bitbucketsync

Replace example.com with your hostname!

Gitlab Webhooks

Open your project on Gitlab and go to Settings -> Integrations and Add webhook with Push events ticked using URL:

https://example.com/bitbucketsync

Replace example.com with your hostname!

If you are running Gitlab locally on same server as Trac, see document below regarding how to safeguard your webhook: https://docs.gitlab.com/ee/security/webhooks.html#webhooks-and-insecure-internal-web-services

Clone your repo locally using SSH keys

In this example I use /var/lib/git as base directory, apache2 runs as www-data on Debian/Ubuntu.

Setup SSH keys for www-data account:

cd /home && sudo mkdir -p www-data && sudo chown -R www-data:www-data www-data
sudo vim /etc/passwd

www-data entry should look something like this:

www-data:x:33:33:www-data:/home/www-data:/bin/bash

NB! Do not use /var/www as home directory since this might expose your private key to the world!

Login as www-data and generate your private/public keys:

sudo su - www-data
chmod 700 ~/.ssh
ssh-keygen -t rsa -b 4096

Open your repository on bitbucket.org and go to Settings -> Access keys and click on Add key and use the contents of the ~/.ssh/id_rsa.pub as key:

ssh-rsa ... www-data@example.com

Similarily for Gitlab, add this key to a new Trac user which has access to your projects.

This will allow the user running the webserver (Trac+BitbucketSyncPlugin) to fetch updates for your repos from Bitbucket whenever the webhook is triggered.

Clone your repository locally

In this example I will use /var/lib/git as base directory, I assume you already have git installed:

cd /var/lib/ && sudo mkdir git && sudo chown www-data git
sudo su - www-data
cd /var/lib/git
git clone git@<example.com>:<path>/<repository>.git

Setup post-receive hook for your local git repository

Add your repository to Trac

Open your Trac installation and go to Admin -> Repositories to add the git repo you just cloned:

Name: <repository>
Type: git
Directory: /var/lib/git/<repository>

Optionally resync as Trac instructs you to.

TracTicketChangesets plugin

If you use the TracTicketChangesets plugin, you need to switch to the branch t7301-mercurial instead of trunk See https://trac-hacks.org/ticket/7301 for more info about the issue with Git/Mercurial and string revisions.

easy_install -Z https://trac-hacks.org/svn/tracticketchangesetsplugin/t7301-mercurial/
cd /usr/local/lib/python2.7/dist-packages/TracTicketChangesets-1.0dev_r0-py2.7.egg
wget https://trac-hacks.org/raw-attachment/ticket/7301/fix-t7301-youngest-rev-handling.diff
patch -p0 < fix-t7301-youngest-rev-handling.diff
wget https://trac-hacks.org/raw-attachment/ticket/7301/fix-t7301-changeset-ticket-displaying.diff
patch -p0 < fix-t7301-changeset-ticket-displaying.diff
# Manually apply 2nd hunk for web_ui.py which fails

Note. paths to the Trac Python plugins may differ depending on your installation.

Edit trac.ini for your environment and add

[ticket-changesets]
showrevlog = false
compact = false

Compacting revisions works for numbers, not so much for strings. Revision logs only lists the numeric revisions, so it is no longer complete.

Debugging

If it still does not work, you can try the following steps:

• Open your repository on bitbucket.org and go to Settings -> Webhooks and click on View requests for your Trac webhook. The status should be 200/green, if not, try to look for any clues in the details.
• tail -f /var/lib/trac/<trac-env>/log/trac.log for your Trac environment while committing to your repository, optionally with log_level = DEBUG in /var/lib/trac/<trac-env>/conf/trac.ini.
