Python script to migrate trac svn commit references to git checksums ([12345] -> [changeset:0123abc])

svn-git-trac - Migrate Trac Tickets Referencing Svn to Git

Will replace all texts in ticket and ticket_changes that reference svn (like [12345]) to the git hash equivalent (like [changeset:0a1bc3f]). Uses sqlalchemy.core for db backend abstraction which enables it to connect to all databases supported by trac.

Requirements

• OSX / Linux
• Python 2.7

Git Svn Repository

For this script to work a git repository must exist on the local machine which was created using git svn clone with metadata intact. To see if your git folder fulfills this requirement try to run the following command:

git svn log --oneline --show-commit

If this command, run in the git folder, returns something along these lines:

r12345 | 0abc123 | Fixed the flux capacitator
...

Then you are good to go!

After running this script, be sure to do the following in Trac:

trac-admin config set git wikishortrev_len 7 trac-admin repository resync "*"

Installation

1. Create a Virtual Environment

   mkdir git-svn-trac cd git-svn-trac virtualenv --no-site-packages -p python2.7 . source bin/activate

2. Run pip, using the requirements fitting for your database

   pip install -r mysql-requirements.txt or pip install -r sqlite-requirements.txt or pip install -r postgres-requirements.txt

3. Create a backup of your git folder and database!

Usage

python git-svn-trac.py gitfolder dsn

git-svn-trac's Issues

Links To Changesets Not Updated

Links to changesets are not properly updated. And if that is fixed, the link is not set, since the text "changeset:" is missing.

Bugfix 1: Regular expression on line 64 is missing a quote. Even better: specify the quotes as optional.
Bugfix 2: Add the text "changeset:" on line 74

Please apply the attached patch: patch.txt
