GTG & liblarch - Week report #06

[Izidor Matušov <izidor matusov gmail com>]

Hi fellow GSoCers and mentors,

I started the last week by a discussion with ploum, my mentor, about the 
concept of rewrite once again. We change the division of 
responsibilities between parts of liblarch which allows us to get rid of 
some redundant code.

With the set goal, I started to rewrite liblarch_gtk part which shows 
nodes to user. Originally it was written as a GenericTreeModel trying to 
protect itself by running in threads. My goal was to make this part as 
small and simple as possible. (KISS) I used TreeStore which is extended 
by handling requests such as add_task, update_task, remove_task and 
reorder. The model stays in consistent state what is good. I discover 
that liblarch part sends sometimes inconsistent requests which breaks 
the old liblarch_gtk. (For usecase "tree high 3 backwards") On the other 
side, there are some constraints which must be solved: the path for tree 
can be 10-item long at maximum.

This week I am going to rewrite liblarch part (MainTree and sending 
requests) which should solve problems with liblarch and satisfy 
testcases [1]. The code base is at [2].

Have a nice week,

Izidor
