I think calling os.Exit at arbitrary points is _bad_ and is good to
delete. I think panics in the case of data courruption have a chance
of providing useful information.

When dialing fails to succeed we should reduce the score of the peer,
which puts the peer at (potentially) greater chances of being removed
from the peer manager, and reduces the chance of the peer being
gossiped by the PEX reactor.
The evidence test produces a set of mock evidence in the evidence pool of the 'Primary' node. The test then fills the evidence pools of secondaries with half of this mock evidence. Finally, the test waits until the secondary has an evidence pool as full as the primary.
The assertions that are removed here were checking that the primary and secondaries' evidence channels were empty. However, nothing in the test actually ensures that the channels are empty. The test only waits for the secondaries to have received the complete set of evidence, and the secondaries already received half of the evidence at the beginning. It's more than possible that the secondaries can receive the complete set of evidence and not finish reading the duplicate evidence off the channels.
As a safety measure, don't allow a query string to be unreasonably
long. The query filter is not especially efficient, so a query that
needs more than basic detail should filter coarsely in the subscriber
and refine on the client side.
This affects Subscribe and TxSearch queries.

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.
This is intended to document some ergonomic and reliability issues with the
existing implementation of the event subscription service on the Tendermint
node, and to discuss possible approaches to improving them.
Prior to #7177, these benchmarks did not provide any useful data about the
performance of the pubsub system (in fact, prior to #7178, half of them did not
work at all).
Specifically, they create a bunch of subscribers with 1 buffer slot on a
default publisher and copy messages to them. But because the publisher is
single-threaded, and doesn't block for delivery, all this tested is how long it
takes to receive a single message from a channel and deliver it to another
channel. The resulting stat does not even vary meaningfully with batch size,
since it's testing a serial workload.
Since #7177 the benchmarks do correctly reflect delivery time (good), but still
do not tell us anything useful: The latencies that matter for pubsub are not
internal queuing, but the effects of backpressure on the publisher via the
subscribers. That's an integration problem, and simulating a fake workload does
not provide meaningful results.
On that basis, remove these benchmarks.
Updates #7156, and a follow-up to #7070.
Event subscriptions in Tendermint currently use a fixed-length Go
channel as a queue. When the channel fills up, the publisher
immediately terminates the subscription. This prevents slow
subscribers from creating memory pressure on the node by not
servicing their queue fast enough.
Replace the buffered channel used to deliver events to buffered
subscribers with an explicit queue. The queue provides a soft
quota and burst credit mechanism: Clients that usually keep up
can survive occasional bursts, without allowing truly slow
clients to hog resources indefinitely.
Fixes#7176. Some of the benchmarks create a bunch of different subscriptions all sharing the same query. These were all using the same client ID, which violates one of the subscriber rules. Ensure each subscriber gets a unique ID.
This has been broken as long as this library has been in the repo—I tracked it back to bb9aa85d and it was already failing there, so I think this never really worked. I'm not sure these test anything useful, but at least now they run.

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.
I saw one of these tests fail and it looks like it was using code that
wasn't being called anywhere, so I deleted it, and avoided the package
name aliasing.
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
