No major changes to the weather alert code have been checked in yet.
I have the new stuff running but still need to work on the expire
code and some other miscellaneous stuff.
I need to make sure I check through the code that decides when to
redraw weather alerts. I'd like it to redraw them only when a real
CHANGE happens to the weather alerts (new/change/expire) instead of
shortly after alerts come in. I think it might be doing the latter
now with both versions of the code. as I'm not sure the code is
accurate right now about what constitutes a change.
If you try to zoom out to U.S. or world level and have weather
alerts streaming in, Xastir will pause for a bit to process each one
and then (much too often) redraw the weather alerts/symbols/tracks.
The only changes that are in there now are minor ones I did last
week. They might have helped a few percent, but weren't what I was
striving for.
So... Better things are coming but I can't check them in yet.
Right now the expire code is segfaulting on me. I could comment out
the expire code and commit it, which would fix your problem, but
then you'd have your weather alert hash table grow over time
unbounded. Better that I get the expire stuff working so that
nobody runs a weird version like that too long.
