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).

Merge pull request #3885 from eddsteel/support-options-requests
Support OPTIONS requests
2018-03-16 09:20:16 -05:00
Paul Banks 69ebbf3e79
Fixes #3891: agent monitor no longer unresponsive before logs stream.
The root cause is actually that the agent's streaming HTTP API didn't flush until the first log line was found which commonly was pretty soon since the default level is INFO. In cases where there were no logs immediately due to level for instance, the client gets stuck in the HTTP code waiting on a response packet from the server before we enter the loop that checks the shutdown channel from the signal handler.

This fix flushes the initial status immediately on the streaming endpoint which lets the client code get into it's expected state where it's listening for shutdown or log lines.

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.

agent: decouple anti-entropy from local state
The anti-entropy code manages background synchronizations of the local
state on a regular basis or on demand when either the state has changed
or a new consul server has been added.

This patch moves the anti-entropy code into its own package and
decouples it from the local state code since they are performing
two different functions.

To simplify code-review this revision does not make any optimizations,
renames or refactorings. This will happen in subsequent commits.

preetapan f6066f8305 Fixes agent error handling when check definition is invalid. Distingu… (#3560)
* Fixes agent error handling when check definition is invalid. Distinguishes between empty checks vs invalid checks

* Made CheckTypes return Checks from service definition struct rather than a new copy, and other changes from code review. This also errors when json payload contains empty structs

* Simplify and improve validate method, and make sure that CheckTypes always returns a new copy of validated check definitions

* Tweaks some small style things and error messages.

* Updates the change log.

Frank Schröder fa22ad4573 config: add generic method to translate between CamelCase and snake_case (#3557)
* doc: document discrepancy between id and CheckID

* doc: document enable_tag_override change

* config: add TranslateKeys helper

TranslateKeys makes it easier to map between different representations
of internal structures. It allows to recursively map alias keys to
canonical keys in structured maps.

* config: use TranslateKeys for config file

This also adds support for 'enabletagoverride' and removes
the need for a separate CheckID alias field.

* config: remove dead code

* agent: use TranslateKeys for FixupCheckType

* agent: translate enable_tag_override during service registration

* doc: add '.hcl' as valid extension

* config: map ScriptArgs to args

* config: add comment for TranslateKeys

DebugConfig and will be documented to change.

Fixes #3530

* config: fix tests

fix data race
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.

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.

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.
