Previously, if a blocking query called CheckConnectServiceNodes
before the gateway-services memdb table had any entries,
a nil watchCh would be returned when calling serviceTerminatingGatewayNodes.
This means that the blocking query would not fire if a gateway config entry
was added after the watch started.
In cases where the blocking query started on proxy registration,
the proxy could potentially never become aware of an upstream endpoint
if that upstream was going to be represented by a gateway.
This commit copies many of the connect-proxy xds testcases and reuses
for ingress gateways. This allows us to more easily see changes to the
envoy configuration when make updates to ingress gateways.
While investigating and fixing an issue on our 1.5.1 branch,
I saw you also/already fixed the bug I found (tags not updated
for existing servers), but comment is misplaced.
This makes it so that both OSS and enterprise tests pass correctly
In the api tests, explicitly set namespace to empty string so that tests
can be shared.
On every service registration, we check to see if a service should be
assassociated to a wildcard gateway-service. This fixes an issue where
we did not correctly check to see if the service being registered was a
"typical" service or not.
A few of the unexported functions in agent/cache took a large number of
arguments. These arguments were effectively overrides for values that
were provided in RequestInfo.
By using a struct we can not only reduce the number of arguments, but
also simplify the logic by removing the need for overrides.
Previously the SupportsBlocking option was specified by a method on the
type, and all the other options were specified from RegisterOptions.
This change moves RegisterOptions to a method on the type, and moves
SupportsBlocking into the options struct.
Currently there are only 2 cache-types. So all cache-types can implement
this method by embedding a struct with those predefined values. In the
future if a cache type needs to be registered more than once with different
options it can remove the embedded type and implement the method in a way
that allows for paramaterization.
* Implements a simple, tcp ingress gateway workflow
This adds a new type of gateway for allowing Ingress traffic into Connect from external services.

The Init method provided the same functionality as the New constructor.
The constructor is both more widely used, and more idiomatic, so remove
the Init method.
This change is in preparation for fixing printing of these IDs.
Also reduce the log level of some version checking messages on the server as they can be pretty noisy during upgrades and really are more for debugging purposes.
This should very slightly reduce the amount of memory required to store each item in
the cache.
It will also enable setting different TTLs based on the type of result. For example
we may want to use a shorter TTL when the result indicates the resource does not exist,
as storing these types of records could easily lead to a DOS caused by
OOM.
These two notify functions are very similar. There appear to be just
enough differences that trying to parameterize the differences may not
improve things.
For now, reduce some of the cosmetic differences so that the material
differences are more obvious.
Use named returned so that the caller has a better idea of what these
bools mean.
Return early to reduce the scope, and make it more obvious what values
are returned in which cases. Also reduces the number of conditional
expressions in each case.
The test had two racy bugs related to memdb references.
The first was when we initially populated data and retained the FederationState objects in a slice. Due to how the `inmemCodec` works these were actually the identical objects passed into memdb.
The second was that the `checkSame` assertion function was reading from memdb and setting the RaftIndexes to zeros to aid in equality checks. This was mutating the contents of memdb which is a no-no.
With this fix, the command:
```
i=0; while /usr/local/bin/go test -count=1 -timeout 30s github.com/hashicorp/consul/agent/consul -run '^(TestReplication_FederationStates)$'; do i=$((i + 1)); printf "$i "; done
```
That used to break on my machine in less than 20 runs is now running 150+ times without any issue.

On recent Mac OS versions, the ulimit defaults to 256 by default, but many
systems (eg: some Linux distributions) often limit this value to 1024.
On validation of configuration, Consul now validates that the number of
allowed files descriptors is bigger than http_max_conns_per_client.
This make some unit tests failing on Mac OS.
Use a less important value in unit test, so tests runs well by default
on Mac OS without need for tuning the OS.
* Enable filtering language support for the v1/connect/intentions listing API
* Update website for filtering of Intentions
* Update website/source/api/connect/intentions.html.md
This change moves all the typeEntry lookups to the first step in the exported methods,
and makes unexporter internals accept the typeEntry struct.
This change is primarily intended to make it easier to extract the container of caches
from the Cache type.
It may incidentally reduce locking in fetch, but that was not a goal.
Sometimes, in the CI, it could receive a SIGURG, producing this line:
FAIL: TestForwardSignals/signal-interrupt (0.06s)
util_test.go:286: expected to read line "signal: interrupt" but got "signal: urgent I/O condition"
Only forward the signals we test to avoid this kind of false positive
