Was overcounting the number of expected closing messages; the resuming
list may have nil entries. Also the full client wasn't closing the watcher
client, only canceling its context, so client closes weren't joining with
the watcher shutdown.
Fixes#6605
Using printf will try to parse the string and replace special
characters. In migrate code, we want to just output the raw
json string of client.Node.
For example,
Printf("%\\") => %!\(MISSING)
Print("%\\") => %\
Thus, we should use print instead.
Move all vote handling from the per-state step functions to the
top-level Step(). This wasn't necessary before because MsgVote would
cause us to become a follower, but MsgPreVote needs to be handled
without changing the node's current state.
Some tests were starting nodes with a non-empty log but a term of zero,
which cannot happen in the real world. This was affecting the final term
being tested in TestLeaderElection.
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).
