-------------------------+-------------------------------------------------
Reporter: annakrat | Owner: grass-dev@…
Type: defect | Status: reopened
Priority: major | Milestone: 7.2.0
Component: PyGRASS | Version: svn-trunk
Resolution: | Keywords: vector, API break, backwards

Unspecified | Platform: All

Comment (by huhabla):
IMHO the former implementation was close to be a bug that was fixed in
trunk. For every new feature a new category was created by default, except
a category was already attached to the c_cat field in the geometry. It was
not obvious howto use the same category for different features.
Replying to [comment:3 wenzeslaus]:
> The following from r68603 is breaking backwards compatibility between
7.0 and 7.2:
>
> {{{
> #!diff
> - def write(self, geo_obj, attrs=None, set_cats=True):
> + def write(self, geo_obj, cat=None, attrs=None):
> }}}
>
> The old API should (must) be accommodated. If the old API is so bad,
that it needs to be replaced (rather than extended), then we should have
one transitional version where both APIs work and the old one gives a
warning. I don't have enough information to make the judgment.

> Related to that, the error message does not give much information about
what is going on.
