# What does this pull request change?
This pull request adds a new runbook for operators enountering errors related to the new Proposer-Based Timestamps algorithm. The goal of this runbook is to give operators a set of clear steps that they can follow if they are having issues producing blocks because of clock synchronization problems.
This pull request also renames the `*PrevoteDelay` metrics to drop the term `MessageDelay`. These metrics provide a combined view of `message_delay` + `synchrony` so the name may be confusing.
# Questions to reviewers
* Are there ways to make the set of steps clearer or are there any pieces that seem confusing?
Fixes#8052 again. Ideally we would have some way of detecting that this
happens before merging, but the way we build docs right now is kind of
complicated.
This change set implements the most recent version of `FinalizeBlock`.
# What does this change actually contain?
* This change set is rather large but fear not! The majority of the files touched and changes are renaming `ResponseDeliverTx` to `ExecTxResult`. This should be a pretty inoffensive change since they're effectively the same type but with a different name.
* The `execBlockOnProxyApp` was totally removed since it served as just a wrapper around the logic that is now mostly encapsulated within `FinalizeBlock`
* The `updateState` helper function has been made a public method on `State`. It was being exposed as a shim through the testing infrastructure, so this seemed innocuous.
* Tests already existed to ensure that the application received the `ByzantineValidators` and the `ValidatorUpdates`, but one was fixed up to ensure that `LastCommitInfo` was being sent across.
* Tests were removed from the `psql` indexer that seemed to search for an event in the indexer that was not being created.
# Questions for reviewers
* We store this [ABCIResponses](5721a13ab1/proto/tendermint/state/types.pb.go (L37)) type in the data base as the block results. This type has changed since v0.35 to contain the `FinalizeBlock` response. I'm wondering if we need to do any shimming to keep the old data retrieveable?
* Similarly, this change is exposed via the RPC through [ResultBlockResults](5721a13ab1/rpc/coretypes/responses.go (L69)) changing. Should we somehow shim or notify for this change?

This change adds an overview of the proposer-based timestamps algorithm. The goal of this documentation is to give a plain enough explanation of the algorithm so that application developers and validators can understand both the utility of the algorithm and understand how the new constrains may affect their network and topology.
I'm blanking on the scheme we decided on for docs linking, so if anyone could remind me what link format we decided on, I'll go clean that up ASAP.
Once this is merged, I intend to create a runbook for chains that see slower block-times or higher nil prevotes and link that runbook to this document to provide a higher-level overview.

Since the goal of reading events at the head of the event log is to satisfy a
subscription style interface, there is no point in allowing head polling with
no wait interval. The pagination case already bypasses long polling, so the
extra option is unneessary.
Set a minimum default long-polling interval for the head case.
Add a test for minimum delay.
* Update ADR template
The reason for this proposed update to the ADR template is twofold:
1. There's currently no easy way to cross-reference between ADRs and
issues/PRs on GitHub. This may be easy to manage for those with
context while they're working on implementing an ADR, but after time
passes and for complex ADRs it gets more difficult for newcomers to
the codebase to track both the implementation status of the ADR or
its historical context and discussions.
2. We should not allow for "proposed" ADRs. An ADR is a **decision
record**, which implies acceptance, and not a proposal. RFCs provide
a mechanism to make proposals.

* Move "Proposed" ToC entries to "Accepted".
It's possible some of these should actually be "Implemented", but I did not try
to go through each one to distinguish.
* Revert "Move "Proposed" ToC entries to "Accepted"."

Found by the link checker.
There are still some links that aren't fixed, because it's not clear where they _should_ point. I just hit the obvious ones.
There are a lot of existing links to the master section of the site, and my
attempts to get a redirector working have so far not succeeded. While it still
makes sense to not publish docs for unreleased code, a 404 is almost certainly
more disruptive than seeing docs for unreleased stuff.
This includes the docs in the build again, but does not add them back to the
selector menu. That allows URLs to resolve but encourages folks to use the
released versions when they have a choice.
I left the redirect for the RPC link in place, since that's still useful.
Updates #7935.
Implement the basic cursor and eventlog types described in ADR 075. Handle
encoding and decoding as strings for compatibility with JSON.
- Add unit tests for the required order and synchronization properties.
- Add hooks for metrics, with one value to be expanded later.
- Update ADR 075 to match the specifics of the implementation so far.
* event: Added Events after evidence validation; evidence: refactored AddEvidence
Added context and Metrics as parameter for the pool constructor
* evidence: pushed event firing into evidence pool and added metrics to represent the size of the evpool
* state: fixed parameters of evpool mock functions
* evidence: added test to confirm events are generated
* Removed obsolete EvidenceEventPublisher interface
* evidence: pool removed error on missing eventbus
The main function defers some things that do not run in the "normal" exit case
because we call os.Exit(0) explicitly. Since falling off the end of main does
the same thing, and also permits defers to run, let's do that.
The original Tendermint implementation provided a fixed, built-in event
indexer, but users would like to plug in different indexing backends. Although
ADR-065 was a good first step toward customization of indexing, its
implementation model does not satisfy all the user requirements. Moreover,
this approach leaves some existing technical issues with indexing unsolved.
This RFC documents these concerns, and discusses some potential approaches to
solving them. It does _not_ propose a specific technical decision. It is meant
to unify and focus some of the disparate discussions of the topic.
While the name including an apostrophe is perfectly legal, it turns out to
confuse some tools that don't escape things properly. Rename to remove the
apostrophe rather than fight the world.
Fixes#7836.
This RFC attempts to explore the requirements for deleting the notion of Gas from Tendermint while allowing applications that need such functionality to build it.
Remove JSON-RPC wrappers from GET output, since they are no longer printed.
Also format examples with jq so they look a little neater.
Fixes#7779.

closes: #7758
This change performs the following:
* Removes the description of the non-proposers waiting
* Removes descriptions of the `Accuracy` parameter that no longer exists
* Corrects the inequality to properly reflect the `timely` check.
* Renames the consensus params to `SynchronyParams`
* Minor cosmetic fixes.
related to: #7274 and #7275
Still somewhat uncertain on two things that I'd appreciate more feedback on:
1. The optional temporary local overrides. Perhaps this is superfluous and we can simply make the transition without the override?
2. If this set of parameters seems to be large enough to allow application developers to create the chains they want but not so large as to be needlessly complex.
