Sean Chittenden 5ac7b893cc Use panic instead of returning a sentinel UUID values in unit tests 2016-02-01 16:42:04 -08:00
Sean Chittenden ef8bbca48f Continually rebalance client connections 
Introduce a low-level background connection expiration mechanism wherein connections will be recycled periodically based on the size and health of the cluster.

For the vast majority of consul users, this will mean an average connection age of 150s.  For 10K node clusters it will take ~3min for clusters to rebalance their connections.  In the pathological case for a 100K cluster where 99K clients are in the minority talking to 1x server it will take ~26min to rebalance all connections.

It's possibe for clients recovering from a parititon to become fixated on a single server until the server or agent is restarted.  This is of particular interest to long-running environments with stable agents, where `allow_stale` is true, and partitions occur periodically.

Sean Chittenden 8a37e76cb0 Use rand.Int31n() vs unconditionally using modulus 2016-01-30 15:47:58 -08:00
Sean Chittenden 727bb42b1d Merge branch 'f-consul-lib' of ssh://github.com/hashicorp/consul into b-redistribute-clients 2016-01-30 15:40:54 -08:00
Sean Chittenden b216d4c11f Rename clientRPCCache to clientRPCConnMaxIdle, change value 
Increase the max idle time for agents talking to servers from 30s to 127s in order to allow for the reuse of connections that are being initiated by cron.

127s was chosen as the first prime above 120s (arbitrarily chose to use a prime) with the intent of reusing connections who are used by once-a-minute cron(8) jobs *and* who use a 60s jitter window (e.g. in vixie cron job execution can drift by up to 59s per job, or 119s for a once-a-minute cron job).

Sean Chittenden 893f91b0d5 Always seed math/rand on consul startup 
Required for jitter calcs.  This could be done in consul/agent, but this makes it clear it is done only once process-wide.

Sean Chittenden c470553b6b Factor out duplicate functions into a lib package 
Consolidate code duplication and tests into a single lib package.  Most of these functions were from various **/util.go functions that couldn't be imported due to cyclic imports.  The consul/lib package is intended to be a terminal node in an import DAG and a place to stash various consul-only helper functions.  Pulled in hashicorp/go-uuid instead of consolidating UUID access.

Jamie Kelly 08eefe7c31 Edit intro to present Consul instead of Terraform. 
As this is Consul, not Terraform, it makes sense to use Consul in this intro instead of Terraform.

Jay Looney 2e5027cdca Fix #1488 
gox doesn't get copied anywhere that might be in the users $PATH by default, however if someone has a functional Go setup they are required to have a $GOPATH variable which will contain their Go workspace and executables of all built go programs under $GOPATH/bin
There are certainly many solutions to this but after reading the Go documentation this seemed to me like it would be the quickest and most cross-platform.
