Matt Keeler 0c44a0a7cc GH-3798: Add HTTP prepared query near=_ip test
Also fixed an issue where we need to have the X-Forwarded-For header processed before the RemoteAddr. This shouldn’t have any functional difference for prod code but for mocked request objects it allows them to work.

Yoann 23a6ad9356 Add support for compression in http api
The need has been spotted in issue https://github.com/hashicorp/consul/issues/3687.
Using "NYTimes/gziphandler", the http api responses can now be compressed if required.
The Go API requires compressed response if possible and handle the compressed response.
We here change only the http api (not the UI for instance).

Edd Steel 40eefc9f7d
Support OPTIONS requests
- register endpoints with supported methods
- support OPTIONS requests, indicating supported methods
- extract method validation (error 405) from individual endpoints
- on 405 where multiple methods are allowed, create a single Allow
  header with comma-separated values, not multiple Allow headers.

Moves ACL disabled response logic down into endpoints.
This lets us make the registration of endpoints less fancy, on the
road to adding a registration mechanism.

agent: add /v1/coordianate/node/:node endpoint
This patch adds a /v1/coordinate/node/:node endpoint to get the network
coordinates for a single node in the network.

Since Consul Enterprise supports network segments it is still possible
to receive mutiple entries for a single node - one per segment.

Frank Schröder c7cc62ab5a agent: consolidate handling of 405 Method Not Allowed (#3405)
* 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.

Frank Schröder 69a088ca85 New config parser, HCL support, multiple bind addrs (#3480)
* 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.

* Upgrade github.com/hashicorp/hcl to support int64

* improve error messages

* fix directory permission test

* Fix rtt test

* Fix ForceLeave test

* Skip performance test for now until we know what to do

* Update github.com/hashicorp/memberlist to update log prefix

* Make memberlist use the default logger

* improve config error handling

* do not fail on non-existing data-dir

* experiment with non-uniform timeouts to get a handle on stalled leader elections

* Run tests for packages separately to eliminate the spurious port conflicts

* refactor private address detection and unify approach for ipv4 and ipv6.

Fixes #2825

* do not allow unix sockets for DNS

* improve bind and advertise addr error handling

* go through builder using test coverage

* minimal update to the docs

* more coverage tests fixed

* more tests

* fix makefile

* monkey patch race condition in go-sockaddr until we understand why that fails

* monkey patch hcl decoder race condidtion until we understand why that fails

* monkey patch spurious errors in strings.EqualFold from here

* add test for hcl decoder race condition. Run with go test -parallel 128

Frank Schröder 44e6b8122d acl: consolidate error handling (#3401)
The error handling of the ACL code relies on the presence of certain
magic error messages. Since the error values are sent via RPC between
older and newer consul agents we cannot just replace the magic values
with typed errors and switch to type checks since this would break
compatibility with older clients.

Therefore, this patch moves all magic ACL error messages into the acl
package and provides default error values and helper functions which
determine the type of error.
