* Fixes handling of stop channel and failed barrier attempts.
There were two issues here. First, we needed to not exit when there
was a timeout trying to write the barrier, because Raft might not
step down, so we'd be left as the leader but having run all the step
down actions.
Second, we didn't close over the stopCh correctly, so it was possible
to nil that out and have the leaderLoop never exit. We close over it
properly AND sequence the nil-ing of it AFTER the leaderLoop exits for
good measure, so the code is more robust.
Fixes#3545

* Adds shell option back to consul exec command.
* Adds shell back into consul watch command.
* Refactors signal forwarding and makes Windows-friendly.
* Adds a clarifying comment.
* Changes error wording to a warning.

* De-nests an if statement.
* config: provide stable config for /v1/agent/self (#3530)
This patch adds a stable subset of the previous Config struct to the
agent/self response. The actual runtime configuration is moved into
DebugConfig and will be documented to change.
Fixes#3530
* config: fix tests
* doc: update api documentation for /v1/agent/self
- Lookup TXT records using recursive lookups
- Expect TXT record equal to value if key starts with rfc1035-
- Expect TXT record in rfc1464 otherwise, i.e. (k=v)
ref #2709
* vendor: add github.com/sergi/go-diff/diffmatchpatch for diff'ing test output
* config: refactor Sanitize to recursively clean runtime config and format complex fields
* Removes an extra int cast.
* Adds a top-level check test case for sanitization.
* Make sure that id and address are set in member created during reaping of catalog nodes that have been removed from serf
* Get address from node table in the state store rather than from service address
* Fix incorrect lookup by checkname instead of node name
* Make sure that serverlookup is called with the right address format, added unit test.
* Address code review comments
* Tweaks style stuff.
* metrics: replace statsite_prefix with service_prefix
The metrics prefix isn't statsite specific and is in fact used
for all metrics providers. Since we are deprecating fields
anyway we should fix this one as well.
Fixes#3293
* Updates docs and sorts telemetry section.
* Renames to "metrics_prefix" to disambiguate with Consul services.
* Updates the change log.
Remove an error in watch reloading that happens when http and https
are both disabled, and use an https address for running watches if
no http addresses are present.
Fixes#3425.
Since state.Checks() returns a shallow copy
its elements must not be modified. Copying
the elements in the handler does not guarantee
consistency since that list is guarded by a different
lock. Therefore, the only solution is to have state.Checks()
return a deep copy.
* agent: consolidate http method not allowed checks
This patch uses the error handling of the http handlers to handle HTTP
method not allowed errors across all available endpoints. It also adds a
test for testing whether the endpoints respond with the correct status
code.
* agent: do not panic on metrics tests
* agent: drop other tests for MethodNotAllowed
* agent: align /agent/join with reality
/agent/join uses PUT instead of GET as documented.
* agent: align /agent/check/{fail,warn,pass} with reality
/agent/check/{fail,warn,pass} uses PUT instead of GET as documented.
* fix some tests
* Drop more tests for method not allowed
* Align TestAgent_RegisterService_InvalidAddress with reality
* Changes API client join to use PUT instead of GET.
* Fixes agent endpoint verbs and removes obsolete tests.
* Updates the change log.
* Changes default Raft protocol to 3.
* Changes numPeers() to report only voters.
This should have been there before, but it's more obvious that this
is incorrect now that we default the Raft protocol to 3, which puts
new servers in a read-only state while Autopilot waits for them to
become healthy.
* Fixes TestLeader_RollRaftServer.
* Fixes TestOperator_RaftRemovePeerByAddress.
* Fixes TestServer_*.
Relaxed the check for a given number of voter peers and instead do
a thorough check that all servers see each other in their Raft
configurations.
* Fixes TestACL_*.
These now just check for Raft replication to be set up, and don't
care about the number of voter peers.
* Fixes TestOperator_Raft_ListPeers.
* Fixes TestAutopilot_CleanupDeadServerPeriodic.
* Fixes TestCatalog_ListNodes_ConsistentRead_Fail.
* Fixes TestLeader_ChangeServerID and adjusts the conn pool to throw away
sockets when it sees io.EOF.
* Changes version to 1.0.0 in the options doc.
* Makes metrics test more deterministic with autopilot metrics possible.
* new config parser for agent
This patch implements a new config parser for the consul agent which
makes the following changes to the previous implementation:
* add HCL support
* all configuration fragments in tests and for default config are
expressed as HCL fragments
* HCL fragments can be provided on the command line so that they
can eventually replace the command line flags.
* HCL/JSON fragments are parsed into a temporary Config structure
which can be merged using reflection (all values are pointers).
The existing merge logic of overwrite for values and append
for slices has been preserved.
* A single builder process generates a typed runtime configuration
for the agent.
The new implementation is more strict and fails in the builder process
if no valid runtime configuration can be generated. Therefore,
additional validations in other parts of the code should be removed.
The builder also pre-computes all required network addresses so that no
address/port magic should be required where the configuration is used
and should therefore be removed.
