Previously config entries sharing a kind & name but in different
namespaces could occasionally cause "stuck states" in replication
because the namespace fields were ignored during the differential
comparison phase.
Example:
Two config entries written to the primary:
kind=A,name=web,namespace=bar
kind=A,name=web,namespace=foo
Under the covers these both get saved to memdb, so they are sorted by
all 3 components (kind,name,namespace) during natural iteration. This
means that before the replication code does it's own incomplete sort,
the underlying data IS sorted by namespace ascending (bar comes before
foo).
After one pass of replication the primary and secondary datacenters have
the same set of config entries present. If
"kind=A,name=web,namespace=bar" were to be deleted, then things get
weird. Before replication the two sides look like:
primary: [
kind=A,name=web,namespace=foo
]
secondary: [
kind=A,name=web,namespace=bar
kind=A,name=web,namespace=foo
]
The differential comparison phase walks these two lists in sorted order
and first compares "kind=A,name=web,namespace=foo" vs
"kind=A,name=web,namespace=bar" and falsely determines they are the SAME
and are thus cause an update of "kind=A,name=web,namespace=foo". Then it
compares "<nothing>" with "kind=A,name=web,namespace=foo" and falsely
determines that the latter should be DELETED.
During reconciliation the deletes are processed before updates, and so
for a brief moment in the secondary "kind=A,name=web,namespace=foo" is
erroneously deleted and then immediately restored.
Unfortunately after this replication phase the final state is identical
to the initial state, so when it loops around again (rate limited) it
repeats the same set of operations indefinitely.
This change attempts to make the delay logic more obvious by:
* remove indirection, inline a bunch of function calls
* move all the code and constants next to each other
* replace the two constant values with a single value
* reword the comments.
When a service is deregistered, we check whever matching services were
registered as sidecar along with it and deregister them as well.
To determine if a service is indeed a sidecar we check the
structs.ServiceNode.LocallyRegisteredAsSidecar property. However, to
avoid interal API leakage, it is excluded from JSON serialization,
meaning it is not persisted to disk either.
When the agent is restarted, this property lost and sidecars are no
longer deregistered along with their parent service.
To fix this, we now specifically save this property in the persisted
service file.
* Consul Service meta wrongly computes and exposes non_voter meta
In Serf Tags, entreprise members being non-voters use the tag
`nonvoter=1`, not `non_voter = false`, so non-voters in members
were wrongly displayed as voter.
Demonstration:
```
consul members -detailed|grep voter
consul20-hk5 10.200.100.110:8301 alive acls=1,build=1.8.4+ent,dc=hk5,expect=3,ft_fs=1,ft_ns=1,id=xxxxxxxx-5629-08f2-3a79-10a1ab3849d5,nonvoter=1,port=8300,raft_vsn=3,role=consul,segment=<all>,use_tls=1,vsn=2,vsn_max=3,vsn_min=2,wan_join_port=8302
```
* Added changelog
* Added changelog entry
* Remove unused StatsCard component
* Create Card and Stats contextual components with styling
* Send endpoint, item, and protocol to Stats as props
* WIP basic plumbing for metrics in Ember
* WIP metrics data source now works for different protocols and produces reasonable mock responses
* WIP sparkline component
* Mostly working metrics and graphs in topology
* Fix date in tooltip to actually be correct
* Clean up console.log
* Add loading frame and create a style sheet for Stats
* Various polish fixes:
- Loading state for graph
- Added fake latency cookie value to test loading
- If metrics provider has no series/stats for the service show something that doesn't look broken
- Graph hover works right to the edge now
- Stats boxes now wrap so they are either shown or not as will fit not cut off
- Graph resizes when browser window size changes
- Some tweaks to number formats and stat metrics to make them more compact/useful
* Thread Protocol through topology model correctly
* Rebuild assetfs
* Fix failing tests and remove stats-card now it's changed and become different
* Fix merge conflict
* Update api doublt
* more merge fixes
* Add data-permission and id attr to Card
* Run JS linter
* Move things around so the tests run with everything available
* Get tests passing:
1. Remove fakeLatency setTimeout (will be replaced with CONSUL_LATENCY
in mocks)
2. Make sure any event handlers are removed
* Make sure the Consul/scripts are available before the app
* Make sure interval gets set if there is no cookie value
* Upgrade mocks so we can use CONSUL_LATENCY
* Fix handling of no series values from Prometheus
* Update assetfs and fix a comment
* Rebase and rebuild assetfs; fix tcp metric series units to be bits not bytes
* Rebuild assetfs
* Hide stats when provider is not configured

Previously, we would emit service usage metrics both with and without a
namespace label attached. This is problematic in the case when you want
to aggregate metrics together, i.e. "sum(consul.state.services)". This
would cause services to be counted twice in that aggregate, once via the
metric emitted with a namespace label, and once in the metric emited
without any namespace label.
