* Add docs for MIME sniffing on metrics endpoint.
This was added in 1.7.2 last year but I realised we don't document it so it's kinda surprising Prometheus "just works" now.
* Update website/content/api-docs/agent/index.mdx
Replace the large table of tests with individual calls to run(). By using
runCase, failure messages will include the line number for the test case, as
well as a line number from the test functions.
Example:
=== FAIL: agent/config TestLoad_IntegrationWithFlags/failing_case (0.01s)
runtime_test.go:4721: case: failing case
runtime_test.go:4864: error "data_dir cannot be empty" does not contain "I expected this error"
Previous:
runtime_test.go:4864: error "data_dir cannot be empty" does not contain "I expected this error"
Without the line number to the testCase data, debugging these tests is
difficult. It is impossible to jump directly to the test case, and
difficult to find the location because of many similarly named cases.
AEInterval is overridden by NonUserSource, so there is no way for a user
to set this value. These two cases represented impossible real world
scenarios.
Instead the test is replaced with one that shows that the AEInterval can
not be set by config.
This change allows us to remove the hcltail and jsontail fields from
testCase
Previously a snapshot created as part of a resumse-stream request could have incorrectly
cached the newSnapshotToFollow event. This would cause clients to error because they
received an unexpected framing event.
10 minutes is the default blocking query timeout. Using the same value results in us hitting
the expired cache entry bug frequently. By extending this TTL we at least mitigate the problem.
The underlying bug still needs to be fixed.
The materializer is often reset when an error is received. By resetting
the retryWaiter we effectively never wait. The retryWaiter should only
be reset when we get an event without error. This is done in
Materializer.updateView().
Streaming can not be used for these queries because the near query
paramter indicates a specific sort of the results, and that sort
requires data that is not available to the client from the streaming
API.
This fixes an issue where leaf certificates issued in primary
datacenters using Vault as a Connect CA would be reissued very
frequently (every ~20 seconds) because the logic meant to detect root
rotation was errantly triggering.
The hash of the rootCA was being compared against a hash of the
intermediateCA and always failing. This doesn't apply to the Consul
built-in CA provider because there is no intermediate in use in the
primary DC.
This is reminiscent of #6513
In a situation where the mesh gateway is configured to bind to multiple
network interfaces, we use a feature called 'tagged addresses'.
Sometimes an address is duplicated across multiple tags such as 'lan'
and 'lan_ipv4'.
There is code to deduplicate these things when creating envoy listeners,
but that code doesn't ensure that the same tag wins every time. If the
winning tag flaps between xDS discovery requests it will cause the
listener to be drained and replaced.
