James Phillips 7e6d52109b Hardens Consul from bad coordinates from other nodes. 2015-10-23 15:23:01 -07:00
James Phillips d12aa2ffab Moves batching down into the state store and changes it to fail-fast. 
* A batch of updates is done all in a single transaction.
* We no longer need to get an update to kick things, there's a periodic flush.
* If incoming updates overwhelm the configured flush rate they will be dumped with an error.

David Adams b7bcb2a414 Add HTTP request header X-Consul-Token 
Add support for an X-Consul-Token HTTP request header to specify the
token with which this request should be fulfilled. The header would have
precedence over the responding Agent's default token, but would have
lower precedence than a token specified in the query string.

Jeff Mitchell f49fc095ef Don't use http.DefaultClient 
Two of the changes are in tests; the one of consequence is in the API.
As explained in #1308 this can cause conflicts with downstream programs.

Fixes #1308.

Wojciech Bederski b014c0f91b make Pause()/Resume()/isPaused() behave more like a semaphore 
see: https://github.com/hashicorp/consul/issues/1173 #1173

Reasoning: somewhere during consul development Pause()/Resume() and
PauseSync()/ResumeSync() were added to protect larger changes to
agent's localState.  A few of the places that it tries to protect are:

- (a *Agent) AddService(...)      # part of the method
- (c *Command) handleReload(...)  # almost the whole method
- (l *localState) antiEntropy(...)# isPaused() prevents syncChanges()

The main problem is, that in the middle of handleReload(...)'s
critical section it indirectly (loadServices()) calls  AddService(...).
AddService() in turn calls Pause() to protect itself against
syncChanges(). At the end of AddService() a defered call to Resume() is
made.

With the current implementation, this releases
isPaused() "lock" in the middle of handleReload() allowing antiEntropy
to kick in while configuration reload is still in progress.
Specifically almost all services and probably all check are unloaded
when syncChanges() is allowed to run.

This in turn can causes massive service/check de-/re-registration,
and since checks are by default registered in the critical state,
a majority of services on a node can be marked as failing.
It's made worse with automation, often calling `consul reload` in close
proximity on many nodes in the cluster.

This change basically turns Pause()/Resume() into P()/V() of
a garden-variety semaphore. Allowing Pause() to be called multiple times,
and releasing isPaused() only after all matching/defered Resumes() are
called as well.

TODO/NOTE: as with many semaphore implementations, it might be reasonable
to panic() if l.paused ever becomes negative.
