e6808c69f8 Increase maximum number of paths per IP scope to 4 
Otherwise, local discovered routes are ignored.
Don't know what the best value would be. Taking 4 for now.

0940d673db Always advertise to the cluster when we have a peer even if we have also initiated handoff. This might be the cause of the warmup problem -- will test later. At the very least it should not hurt anything due to pick-latest logic and the fact that cluster members with only suboptimal paths do not respond to WANT_PEER. 2015-11-11 14:36:22 -08:00

3ba54c7e35 Eliminate some poorly thought out optimizations from the netconf/controller interaction, 
and go ahead and bump version to 1.0.4.

For a while in 1.0.3 -dev I was trying to optimize out repeated network controller
requests by using a ratcheting mechanism. If the client received a network config
that was indeed different from the one it had, it would respond by instantlly
requesting it again.

Not sure what I was thinking. It's fundamentally unsafe to respond to a message
with another message of the same type -- it risks a race condition. In this case
that's exactly what could happen.

It just isn't worth the added complexity to avoid a tiny, tiny amount of network
overhead, so I've taken this whole path out.

A few extra bytes every two minutes isn't worth fretting about, but as I recall
the reason for this optimization was to save CPU on the controller. This can be
achieved by just caching responses in memory *there* and serving those same
responses back out if they haven't changed.

I think I developed that 'ratcheting' stuff before I went full time on this. It's
hard to develop stuff like this without hours of sustained focus.

57c7992c78 GitHub issue #191 - kill intra-network multicast rate limits (which were not well supported or easily configurable anyway) -- this is really left over from the old collaborative multicast propagation algorithm. New algorithm (in for a while) has been sender-side replication in which sender "pays" all bandwidth, which intrinsically limits multicast. 2015-06-26 12:36:45 -07:00

c287ae4d1d Redo conversion of _networks to a vector. Just use a simple linear search and put the nwid in a pair with the pointer so linear search can be done without pointer chasing. This should be the fastest option for anything less than dozens of networks, and should save memory over the old map. 2015-06-26 11:38:31 -07:00

2b04ac5e9b replace _networks map by vector 
_networks is usually quite small, using binary search on a vector might be faster comapred to std::map.
This is especially true when using uClibc++, which uses a list.

7619b0ecbd Send multicasts in random order. 
This should not affect most users, but on large networks it should cause service
announcements to work a lot better. This is the result of a prolonged discussion
with a user about the visibility of game servers on a large network. The old
multicast algorithm was de-facto randomized due to its distributed nature, while
the new algorithm is more deterministic. This will restore some randomization
beyond limit-overflow conditions.

It won't affect small networks at all.
