Question

I have a few custom ticket fields defined in a global config inherited by all our Trac environments. Now I’d like to remove a few of them only for a single environment (but without having to un-inherit the global config which sets a lot more than just the custom fields). The perhaps obvious way

[ticket-custom]
mycustomfield =

did not work. Is there any way?

Answer 1

No, there’s no limitation for inheritance in general. So you can’t stop a configuration part from propagation, once it’s inherited.

You could construct a slightly more fragmented inheritance instead of ditching inheritance to still reach your goal:

global_trac.ini:

all the basic, common stuff

[ticket-custom]
put reduced, common set of custom fields here

global_trac_with_custom_fields.ini:

[inherit]
file = ../global_trac.ini

[ticket-custom]
put full set of custom fields here

your_special_trac_env/conf/trac.ini:

[inherit]
file = ../global_trac.ini

some_other_trac_env/conf/trac.ini:

[inherit]
file = ../global_trac_with_custom_fields.ini
