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.
So that all the client side filtering is in the same place. Previously
only the bexpr filter was in the cache-entry.
Also makes a small change to the filtering so that instead of rebuilding
slices of items, the filtering can return a bool to determine if the
event payload is saved or not.
Send empty array [] instead of [""] in DNS requests when TagFilter is not set
Do not change case sensitivity of services anymore in `getServiceNodes()` since
cache keys are now case insensitive
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.
An old PR (#7623) was merged after #9585. The old code was incompatible with the new
changes, but none of the lines caused a git conflict so the merge was allowed.
The incompatible changes caused the tests to fail. This fixes the old code to
work with the new changes.
