This bug would result in the UI not having the correct settings in
Consul enterprise, which could produce many warnings in the logs.
This bug occured because the index page, which includes a map of configuration
was rendered when the HTTPHandler is first created. This PR changes the
UIServer to instead render the index page when the page is requested.
The rendering does not appear to be all that expensive, so rendering it
when requested should not cause much extra latency.
Previously we were encoding the UUID as a string, but the index it references uses a UUID
so this index can also use an encoded UUID to save a bit of memory.
Prefix queries are generally being used to match part of a partial
index. We can support these indexes by using a function that accept
different types for each subset of the index.
What I found interesting is that in the generic StringFieldIndexer the
implementation for PrefixFromArgs would remove the trailing null, but
at least in these 2 cases we actually want a null terminated string.
We simply want fewer components in the string.
Some TLS servers require SNI, but the Golang HTTP client doesn't
include it in the ClientHello when connecting to an IP address. This
change adds a new TLSServerName field to health check definitions to
optionally set it. This fixes#9473.
The TestServiceHealthEventsFromChanges function was over 1400 lines.
Attempting to debug test failures in test functions this large is
difficult. It requires scrolling to the line which defines the testcase
because the failure message only includes the line number of the
assertion, not the line number of the test case.
This is an excellent example of where test tables stop working well, and
start being a problem. To mitigate this problem, the runCase pattern can
be used. When one of these tests fails, a failure message will print the
line number of both the test case and the assertion. This allows a
developer to quickly jump to both of the relevant lines, signficanting
reducing the time it takes to debug test failures.
For example, one such failure could look like this:
catalog_events_test.go:1610: case: service reg, new node
catalog_events_test.go:1605: assertion failed: values are not equal
ResolveServiceConfig is called by service manager before the proxy
registration is in the catalog. Therefore we should pass proxy
registration flags in the request rather than trying to fetch
them from the state store (where they may not exist yet).
This is done because after removing ID and NodeName from
ServiceConfigRequest we will no longer know whether a request coming in
is for a Consul client earlier than v1.10.
This enables it to be called for many upstreams or downstreams of a
service while only querying intentions once.
Additionally, decisions are now optionally denied due to L7 permissions
being present. This enables the function to be used to filter for
potential upstreams/downstreams of a service.
Previously this type was defined in structs, but unlike the other types in structs this type
is not used by RPC requests. By moving it to state we can better indicate that this is not
an API type, but part of the state implementation.
I added this recently without realizing that the method already existed and was named
NamespaceOrEmpty. Replace all calls to GetNamespace with NamespaceOrEmpty or NamespaceOrDefault
as appropriate.
Document that this comparison should roughly match MatchesKey
Only sort by overrideKey or service name, but not both
Add namespace to the sort.
The client side also builds a map of these based on the namespace/node/service key, so the only order
that really matters is the ordering of register/dereigster events.
Refactored out a function that can be used for both the snapshot and stream of events to translate
an event into an appropriate connect event.
Previously terminating gateway events would have used the wrong key in the snapshot, which would have
caused them to be filtered out later on.
Also removed an unused function, and some commented out code.
Health of a terminating gateway instance changes
- Generate an event for creating/destroying this instance of the terminating gateway,
duplicate it for each affected service

Previous to this commit, the API response would include Gateway
Addresses in the form `domain.name.:8080`, which due to the addition of
the port is probably not the expected response.
This commit rightTrims any `.` characters from the end of the domain
before formatting the address to include the port resulting in
`domain.name:8080`
Since we currently do no version switching this removes 75% of the PR
noise.
To generate all *.golden files were removed and then I ran:
go test ./agent/xds -update
Note that this does NOT upgrade to xDS v3. That will come in a future PR.
Additionally:
- Ignored staticcheck warnings about how github.com/golang/protobuf is deprecated.
- Shuffled some agent/xds imports in advance of a later xDS v3 upgrade.
- Remove support for envoy 1.13.x but don't add in 1.17.x yet. We have to wait until the xDS v3 support is added in a follow-up PR.
Fixes#8425
When de-registering in anti-entropy sync, when there is no service or
check token.
The agent token will fall back to the default (aka user) token if no agent
token is set, so the existing behaviour still works, but it will prefer
the agent token over the user token if both are set.
ref: https://www.consul.io/docs/agent/options#acl_tokens
The agent token seems more approrpiate in this case, since this is an
"internal operation", not something initiated by the user.
These new functional indexers provide a few advantages:
1. enterprise differences can be isolated to a single function (the
indexer function), making code easier to change
2. as a consequence of (1) we no longer need to wrap all the calls to
Txn operations, making code easier to read.
3. by removing reflection we should increase the performance of all
operations.
One important change is in making all the function signatures the same.
https://blog.golang.org/errors-are-values
An extra boolean return value for SingleIndexer.FromObject is superfluous.
The error value can indicate when the index value could not be created.
By removing this extra return value we can use the same signature for both
indexer functions.
This has the nice properly of a function being usable for both indexing operations.
By using a new pattern for more specific indexes. This allows us to use
the same index for both service checks and node checks. It removes the
abstraction around memdb.Txn operations, and isolates all of the
enterprise differences in a single place (the indexer).
* A GET of the /acl/auth-method/:name endpoint returns the fields
MaxTokenTTL and TokenLocality, while a LIST (/acl/auth-methods) does
not.
The list command returns a filtered subset of the full set. This is
somewhat deliberate, so that secrets aren't shown, but the TTL and
Locality fields aren't (IMO) security critical, and it is useful for
the front end to be able to show them.
For consistency these changes mirror the 'omit empty' and string
representation choices made for the GET call.
This includes changes to the gRPC and API code in the client.
The new output looks similar to this
curl 'http://localhost:8500/v1/acl/auth-methods' | jq '.'
