src/zmapThreads/TODO

-
-- need to introduce pthreads_cancel_points into the code so that a cancel
-will interrupt at good places....some thought needed here though to ensure
-that we don't just litter the code with cancel points making it hard to
-maintain...
-
-I think to some extent the main network reading calls get interrupted by
-a cancel so that makes it all work better.

src/zmapView/TODO

-
-
-The merge is not as simple as I thought, need to either copy everything that is to be merged
-(seems wasteful) or we need to NULL out/remove the things we have transferred....perhaps not
-so hard....
-
-Main thing is to protect whole GDatas that we move into our new sets and null out ones we
-don't want. But also, what happens to datastructs of features that we have allocated but
-no longer need...they should be freed....
-
-Sounds like merge needs to be in some separate feature code package....
-
-It can be done but needs thought..........
-
-Currently we just don't free the stuff...and we should leave it like this for ISMB.
-
-This must be sorted out afterwards otherwise it will use up a lot of memory.
