I move the checker logic from tester to cluster so that stressers and checkers can be initialized at the same time.
this is useful because some checker depends on stressers.
The simpleBalancer.Get() blocks grpc.Invoke() even when the Invoke() is called
with the FailFast option. Therefore currently any requests with the
FastFail option actually doesn't fail fast. They get blocked when there is
no endpoints available.
Get() method needs to respect the BlockingWait option when
picks up an endpoint address from the list and fail immediately when the option is
enabled and no endpoint is available.
The cost of bcrypt password checking is quite high (almost 100ms on a
modern machine) so executing it in apply loop will be
problematic. This commit exclude the checking mechanism to the API
layer. The password checking is validated with the OCC like way
similar to the auth of serializable get.
This commit also removes a unit test of Authenticate RPC from
auth/store_test.go. It is because the RPC now accepts an auth request
unconditionally and delegates the checking functionality to
authStore.CheckPassword() (so a unit test for CheckPassword() is
added). The combination of the two functionalities can be tested by
e2e (e.g. TestCtlV3AuthWriteKey).
Fixes https://github.com/coreos/etcd/issues/6530
This commit adds a new option --check-key to endpoint health command
for health checking with a custom key. It is mainly for avoiding
permission problem.
This commit adds a new option -failure-wrapper to etcd-tester. The
option receives a path of script that is used for enabling/disabling
external fault injectors. The script is called with an option "enable"
when it needs to be enabled (when failure.Inject() is called) and
called with "disabled" in an opposite case (when failure.Recover() is
called).
When running test suites for a client locally I'm getting spammed by log
lines such as:
etcdserver: apply entries took too long [14.226771ms for 1 entries]
The comments in #6278 mention there were future plans of increasing the
threshold for logging these warnings, but it hadn't been done yet.
Previous implementation watches a single key so there's no way
to have separate hosts associate with separate keys for a single
grpc target. Instead, accept all keys on a prefix.
Also fixes first the Next() to read current name data from etcd instead
of waiting for the next event on a synced watcher.
