Release v1.5.0 2019-05-08 18:34:08 +00:00
Matt Keeler 07f2854683 Fixes race condition in Agent Cache (#5796)
* Fix race condition during a cache get

Check the entry we pulled out of the cache while holding the lock had Fetching set.
If it did then we should use the existing Waiter instead of calling fetch. The reason
this is better than just calling fetch is that fetch re-gets the entry out of the
entries map and the previous fetch may have finished. Therefore this prevents
erroneously starting a new fetch because we just missed the last update.

* Fix race condition fully

The first commit still allowed for the following scenario:

• No entry existing when checked in getWithIndex while holding the read lock
• Then by time we had reached fetch it had been created and finished.

* always use ok when returning

* comment mentioning the reading from entries.

* use cacheHit consistently

Copy the proxy config instead of direct assignment (#5786)
This prevents modifying the data in the state store which is supposed to be immutable.

* Add integration test for central config; fix central config WIP

* Add integration test for central config; fix central config WIP

* Set proxy protocol correctly and begin adding upstream support

* Add upstreams to service config cache key and start new notify watcher if they change.

This doesn't update the tests to pass though.

* Fix some merging logic get things working manually with a hack (TODO fix properly)

* Simplification to not allow enabling sidecars centrally - it makes no sense without upstreams anyway

* Test compile again and obvious ones pass. Lots of failures locally not debugged yet but may be flakes. Pushing up to see what CI does

* Fix up service manageer and API test failures

* Remove the enable command since it no longer makes much sense without being able to turn on sidecar proxies centrally

* Remove version.go hack - will make integration test fail until release

* Remove unused code from commands and upstream merge

* Re-bump version to 1.5.0

Matt Keeler ea6cbf01a5 Centralized Config CLI (#5731)
* Add HTTP endpoints for config entry management

* Finish implementing decoding in the HTTP Config entry apply endpoint

* Add CAS operation to the config entry apply endpoint

Also use this for the bootstrapping and move the config entry decoding function into the structs package.

* First pass at the API client for the config entries

* Fixup some of the ConfigEntry APIs

Return a singular response object instead of a list for the ConfigEntry.Get RPC. This gets plumbed through the HTTP API as well.

Dont return QueryMeta in the JSON response for the config entry listing HTTP API. Instead just return a list of config entries.

* Minor API client fixes

* Attempt at some ConfigEntry api client tests

These don’t currently work due to weak typing in JSON

* Get some of the api client tests passing

* Implement reflectwalk magic to correct JSON encoding a ProxyConfigEntry

Also added a test for the HTTP endpoint that exposes the problem. However, since the test doesn’t actually do the JSON encode/decode its still failing.

* Move MapWalk magic into a binary marshaller instead of JSON.

* Add a MapWalk test

* Get rid of unused func

* Get rid of unused imports

* Fixup some tests now that the decoding from msgpack coerces things into json compat types

* Stub out most of the central config cli

Fully implement the config read command.

* Basic config delete command implementation

* Implement config write command

* Implement config list subcommand

Not entirely sure about the output here. Its basically the read output indented with a line specifying the kind/name of each type which is also duplicated in the indented output.

* Update command usage

* Update some help usage formatting

* Add the connect enable helper cli command

* Update list command output

* Rename the config entry API client methods.

* Use renamed apis

* Implement config write tests

Stub the others with the noTabs tests.

* Change list output format

Now just simply output 1 line per named config

* Add config read tests

* Add invalid args write test.

* Add config delete tests

* Add config list tests

* Add connect enable tests

* Update some CLI commands to use CAS ops

This also modifies the HTTP API for a write op to return a boolean indicating whether the value was written or not.

* Fix up the HTTP API CAS tests as I realized they weren’t testing what they should.

* Update config entry rpc tests to properly test CAS

* Fix up a few more tests

* Fix some tests that using ConfigEntries.Apply

* Update config_write_test.go

* Get rid of unused import

Ensure ServiceName is populated correctly for agent service checks
Also update some snapshot agent docs

* Enforce correct permissions when registering a check

Previously we had attempted to enforce service:write for a check associated with a service instead of node:write on the agent but due to how we decoded the health check from the request it would never do it properly. This commit fixes that.

* Update website/source/docs/commands/snapshot/agent.html.markdown.erb

R.B. Boyer 9542fdc9bc acl: adding Roles to Tokens (#5514)
Roles are named and can express the same bundle of permissions that can
currently be assigned to a Token (lists of Policies and Service
Identities). The difference with a Role is that it not itself a bearer
token, but just another entity that can be tied to a Token.

This lets an operator potentially curate a set of smaller reusable
Policies and compose them together into reusable Roles, rather than
always exploding that same list of Policies on any Token that needs
similar permissions.

This also refactors the acl replication code to be semi-generic to avoid
3x copypasta.

R.B. Boyer f43bc981e9 making ACLToken.ExpirationTime a *time.Time value instead of time.Time (#5663)
This is mainly to avoid having the API return "0001-01-01T00:00:00Z" as
a value for the ExpirationTime field when it is not set. Unfortunately
time.Time doesn't respect the json marshalling "omitempty" directive.

proxy, and read upstreams from the catalog.

Move the watch package into the api module (#5664)
* Move the watch package into the api module

It was already just a thin wrapper around the API anyways. The biggest change was to the testing. Instead of using a test agent directly from the agent package it now uses the binary on the PATH just like the other API tests.

The other big changes were to fix up the connect based watch tests so that we didn’t need to pull in the connect package (and therefore all of Consul)

Aestek 6762eeb03c Add support for DNS config hot-reload (#4875)
The DNS config parameters `recursors` and `dns_config.*` are now hot
reloaded on SIGHUP or `consul reload` and do not need an agent restart
to be modified.
Config is stored in an atomic.Value and loaded at the beginning of each
request. Reloading only affects requests that start _after_ the
reload. Ongoing requests are not affected. To match the current
behavior the recursor handler is loaded and unloaded as needed on config
reload.

Filter non-passing nodes without modifying cache 2019-04-16 10:29:34 -06:00
Matt Keeler ac78c23021
Implement data filtering of some endpoints (#5579)
Fixes: #4222 

# Data Filtering

This PR will implement filtering for the following endpoints:

## Supported HTTP Endpoints

- `/agent/checks`
- `/agent/services`
- `/catalog/nodes`
- `/catalog/service/:service`
- `/catalog/connect/:service`
- `/catalog/node/:node`
- `/health/node/:node`
- `/health/checks/:service`
- `/health/service/:service`
- `/health/connect/:service`
- `/health/state/:state`
- `/internal/ui/nodes`
- `/internal/ui/services`

More can be added going forward and any endpoint which is used to list some data is a good candidate.

## Usage

When using the HTTP API a `filter` query parameter can be used to pass a filter expression to Consul. Filter Expressions take the general form of:

```
<selector> == <value>
<selector> != <value>
<value> in <selector>
<value> not in <selector>
<selector> contains <value>
<selector> not contains <value>
<selector> is empty
<selector> is not empty
not <other expression>
<expression 1> and <expression 2>
<expression 1> or <expression 2>
```

Normal boolean logic and precedence is supported. All of the actual filtering and evaluation logic is coming from the [go-bexpr](https://github.com/hashicorp/go-bexpr) library

## Other changes

Adding the `Internal.ServiceDump` RPC endpoint. This will allow the UI to filter services better.
