Trac currently supports one set of priorities and severities per
environment. Type-specific ticket workflow is available even in several
Trac plugins from trac-hacks.org [1][2][3], but not much more about
type-specific things that I'm aware of.

Hi,

Thanks for replying.

I'm new in trac development/modification. My experience is around 1 year with trac. (installing & maintaining trac, moving trac and svn repos across the platforms, modyfying the ticket flow, writing wiki, etc).

Right know I'd like to do some more modifications. The first one I'm thinking of is to filter-out priorities lists and severities list depending on the ticket type.

I've read the tracDev page http://trac.edgewall.org/wiki/TracDev.

My question is: what I shall to write? A plugin? A macro? A module?

Thanks a lot in advance for any information.

Kamil

I suppose you must write a plugin.

SimpleMultiProjectPlugin [1] provides a filtering of ticket field 'component' depending on custom ticket field 'project' which is quite similar to what you want to do. Maybe you can have a look at the sources and use it as template for your new plugin.

You need
1. a mapping table in trac.db which maps your priorities and severities to ticket types. In SimpleMultiProjectPlugin , have a look at access to table smp_component_project.
2. a webinterface GUI for mapping. Look at admin_component.py [2].
3. to filter the "New/Modify Ticket" processing in ticket.html for only offering the values you allow for certain ticket types. Have a look at post_process_request() in ticket.py [3], there it offers only 'components' appropriate to the chosen value in ticket field 'project' by using get_projects_component() to access the mapping mentioned in 1. and 2..

I found it useful as different priorities and severities lists could be valid for tasks, bugs and requirements types of tickets.

TracTicketChainedFieldsPlugin may do what you want.
