This pull request merges in the changes for implementing Proposer-based timestamps into `master`. The power was primarily being done in the `wb/proposer-based-timestamps` branch, with changes being merged into that branch during development. This pull request represents an amalgamation of the changes made into that development branch. All of the changes that were placed into that branch have been cleanly rebased on top of the latest `master`. The changes compile and the tests pass insofar as our tests in general pass.
### Note To Reviewers
These changes have been extensively reviewed during development. There is not much new here. In the interest of making effective use of time, I would recommend against trying to perform a complete audit of the changes presented and instead examine for mistakes that may have occurred during the process of rebasing the changes. I gave the complete change set a first pass for any issues, but additional eyes would be very appreciated.
In sum, this change set does the following:
closes#6942
merges in #6849
This change has two main effects:
1. Remove most of the Async methods from the abci.Client interface.
Remaining are FlushAsync, CommitTxAsync, and DeliverTxAsync.
2. Rename the synchronous methods to remove the "Sync" suffix.
The rest of the change is updating the implementations, subsets, and mocks of
the interface, along with the call sites that point to them.
* Fix stringly-typed mock stubs.
* Rename helper method.
Defines a different concrete type that satisfies the service interface for a seed node.
update the seed node unit test to assert the new type.
Fixes#6775
This continues the push of plumbing contexts through tendermint. I
attempted to find all goroutines in the production code (non-test) and
made sure that these threads would exit when their contexts were
canceled, and I believe this PR does that.
Some of our tests were creating a psql event sink and expecting
it to report (or not report) certain kinds of errors. These tests
were ill-founded in a couple of ways:
1. Tests that required the Postgres driver were not loading it.
This led to spurious successes on tests that wanted "some error"
from the sink constructor, but didn't exercise the right path.
2. Tests that wanted a Postgres sink to succeed without a database.
These tests "passed" because they weren't actually establishing a
connection to the database, but if they had would have failed for
the lack of one.
To fix this:
- Load the postgres driver in tests that need it.
- Verify connectivity before reporting successful creation of a PSQL event sink.
- Remove tests that wanted a psql sink without a database, since that case
is already tested elsewhere.
This is a very small change, but removes a method from the
`service.Service` interface (a win!) and forces callers to explicitly
pass loggers in to objects during construction rather than (later)
injecting them. There's not a real need for this kind of lazy
construction of loggers, and I think a decent potential for confusion
for mutable loggers.
The main concern I have is that this changes the constructor API for
ABCI clients. I think this is fine, and I suspect that as we plumb
contexts through, and make changes to the RPC services there'll be a
number of similar sorts of changes to various (quasi) public
interfaces, which I think we should welcome.
This follows the same model as we did in the p2p package.
Rework the indexer service constructor to take a struct of arguments,
that makes it easier to construct the optional settings.
Deprecate but do not remove the existing constructor.
Clean up node initialization a little bit.
This is part of the work described by #7156.
Remove "unbuffered subscriptions" from the pubsub service.
Replace them with a dedicated blocking "observer" mechanism.
Use the observer mechanism for indexing.
Add a SubscribeWithArgs method and deprecate the old Subscribe
method. Remove SubscribeUnbuffered entirely (breaking).
Rework the Subscription interface to eliminate exposed channels.
Subscriptions now use a context to manage lifecycle notifications.
Internalize the eventbus package.
The main (and minor) win of this PR is that the transport is fully the
responsibility of the router and the node doesn't need to be responsible for its lifecylce.
We stopped testing these configurations a while ago, and it doesn't
really make sense to allow nodes to run in this configuration. This
drops support for non-blocksync nodes and cleans up the
configuration/tests accordingly.
Closes: #6908
This is, perhaps, the trival final piece of #7075 that I've been
working on.
There's more work to be done:
- push more of the setup into the pacakges themselves
- move channel-based sending/filtering out of the
- simplify the buffering throuhgout the p2p stack.
