This script was used to migrate data of our trac installation (around 1'800 tickets) to Github Issues. It writes json files as specified in APIv3. Partially based on github-trac-ticket-import by @adamcik.

Since the migration happened already, i'm not actively testing nor maintaining this code any longer. Feel free to ask questions though if something is horribly unclear!

The basic assumptions made should be documented in convert.py. You will definitely need to edit data.py, which we didn't bother converting to YAML.

Find below documentation for our specific migration needs and the MIT license.

Extract newest sql stuff from trac (web interface and db), I use the phpmyadmin account

SELECT ticket, time, author, newvalue FROM ticket_change
  WHERE field='comment' AND newvalue AND time > FILL-IN-DATE-HERE
	ORDER BY time DESC

Click export, export as csv, save as updated-comments.csv with these options:

	terminated by ,
	enclosed by '
	escaped by \
	AUTO NULL
	no no

Process the resulting file in e.g. vim as you need ( %s,\\','',g )

Append the file to comments.csv ( cat updated-comments.csv >> comments.csv )

python2 convert.py

If there is any output besides a list of tickets, check that malformed row in csv

Probably missed some sort of escaping or the replacement algorithm went really wild

When everything looks good:

tar -czf unknown-horizons.tar.gz unknown-horizons/

And bother a poor github admin once more!
