My company is looking to extend Trac in order to allow us to specify
certain comments as being public or private (depending on whether we go
with blacklist or whitelist approach).
I would assume that the best way to go about this would be to create a
plugin implementing the ITicketChangeListener interface. (If not, what
would?)
Actually it's not that simple as there is no interface that already
does what you need.
I'd recommend the following approach:
1. Write something so you can suppress some comments from being shown:
for example just the first comment (=> proof that you can add your
own logic).
Could be that you have to modify Ticket.get_changelog. Which in turn
requires to write your own TicketModule+TicketSystem (or modify the
existing ones with inheritance)
2. Decide how you store the public/private data (might be hard because
of the denormalized storage of comments)
3. Write a ticket change listener as you proposed
4. inject your UI (can be done by an IRequestFilter)
5. write a some RequestHandler so you can set/unset the public/private
for a comment

Ok, we managed to bypass most of that by scrapping the checkbox and and
just adding a string ('[public]') to the comment itself, and then adding
a couple of lines to grouped_changelog_entries in ticket/web_ui.py
However, we'd like the process to be transparent (and non-optional) for
certain users. Essentially, we want to prepend '[public]' to the comment
on the way into the database if a user lacks certain permissions (and/or
is part of a certain usergroup). Where/how is it best to go about this?
We don't mind hacking around in the core, but if there's a maintainable
way that's just as easy, that would be better.
Thanks
