Re: Evince threading update

[Marco Pesenti Gritti <mpgritti gmail com>]

I'm going to work on these... I looked in it a bit and I think the
following are the viable solutions on the short term (first release):
 
>  * links

I'm going to create the EvPage abstraction. I think it will avoid code
duplication. We can access the pixbuf with ev_page_get_pixbuf.

ev_page_get_link will behave just like ev_document_get_link.

>  * search

We need an EvTextPage object/interface with a find method. I think
this can fully replace EvDocumentSearch. Text page rendering will be
managed through the job queue.
This interface should work both using the same thread than creating a
separate one for text rendering.

>  * selection

There are two possible approaches here:

1 Have ev_page_get_text. We are already rendering a text page every
time we do a page rendering in GdkOutputDevice, so this should just
work.
2 Stop doing a page rendering every time and do it only when the user
selected something. (If we arent fast enough this will fail too).

I think we should go for with 1 at least until we have better
selection support in poppler. Less changes and less problems.

>  * saving

Using mutex should work ok for now.

Also I'm going to port the ps backend.
