The problem with the `TestStateFullRound1` is that the state that we are observeing, `cs`, can advance to the next height before we query its data. Specifically, on line `388`, when we called `validatePrevote`, the `cs` State had already advanced to height 2, so querying that State for the votes of height 1 either yielded nil or an erroneous value. This change adds a `ensurePrevoteMatch` function that checks that the prevote occurred and checks that it is for the expected block at the same time. If this change looks reasonable I can just apply the same fix to all of the places where we perform `ensurePrevote` followed by `validatePrevote` to use this function instead.
*light: rpc /status returns status of light client ; code refactoring
light: moved lightClientInfo into light.go, renamed String to ID
test/e2e: Return light client trusted height instead of SyncInfo trusted height
test/e2e/start.go: Not waiting for light client to catch up in tests. Removed querying of syncInfo in start if the node is a light node
* light: Removed call to primary /status. Added trustedPeriod to light info
* light/provider: added ID function to return IP of primary and witnesses
* light/provider/http/http_test: renamed String() to ID()
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.
After #7592, @cmwaters noticed that the logic for re-using old timestamps for proposals may not work with proposer-based timestamps. This change removes the logic to re-use old proposal timestamps since it is no longer correct. Two proposals with different timestamps can no longer be treated as equivalent. Signing a proposal that only differs by timestamp in the new algorithm can be thought of as roughly equivalent to signing a proposal that only differs by `BlockID` in the old scheme.
I also investigated the codebase and checked for any place we updated a timestamp using the pattern `(Timestamp = |Timestamp: )` and saw no additional places where we are updating the timestamp of a proposal message.
Here is the output of that search:

This averts a log-after-close issue. We should probably also chase the shutdown
issues, but since ABCI clients should generally only shut down once per process
I don't think this is a real priority, and the trace is hairy.
The test filter was looking for "TestGoFiles", which does not include tests in

Updates #7626 and #7634.
The interaction between defers and t.Cleanup can be delicate.
For this case, which regularly flakes in CI, be explicit:
Defer the closes and waits before making any attempt to leaktest.
During file rotation and WAL shutdown, there was a race condition between users
of an autofile and its termination. To fix this, ensure operations on an
autofile are properly synchronized, and report errors when attempting to use an
autofile after it was closed.
Notably:
- Simplify the cancellation protocol between signal and Close.
- Exclude writers to an autofile during rotation.
- Add documentation about what is going on.
There is a lot more that could be improved here, but this addresses the more
obvious races that have been panicking unit tests.
## What does this pull request do?
This pull requests adds two metrics intended for use in calculating an experimental value for `MessageDelay`.
The metrics are as follows:
```
# HELP tendermint_consensus_complete_prevote_message_delay Difference in seconds between the proposal timestamp and the timestamp of the prevote that achieved 100% of the voting power in the prevote step.
# TYPE tendermint_consensus_complete_prevote_message_delay gauge
tendermint_consensus_complete_prevote_message_delay{chain_id="test-chain-aZbwF1"} 0.013025505
# HELP tendermint_consensus_quorum_prevote_message_delay Difference in seconds between the proposal timestamp and the timestamp of the prevote that achieved a quorum in the prevote step.
# TYPE tendermint_consensus_quorum_prevote_message_delay gauge
tendermint_consensus_quorum_prevote_message_delay{chain_id="test-chain-aZbwF1"} 0.013025505
```
## Why this change?
For more information on what these metrics are calculating, see #7202. The aim is to merge to backport these metrics to v0.34 and run nodes on a few popular chains with these metrics to determine the experimental values for `MessageDelay` on these popular chains and use these to select our default `SynchronyParams.MessageDelay` value.
## Why Gauges for the metrics?
Gauges allow us to overwrite the metric on each successive observation. We can then capture these metrics over time to track the highest and lowest observed value.
This commit changes the behaviour of the /unconfirmed_txs endpoint by replacing limit with a page and perPage parameter for pagination.
The test case for unconfirmed_txs have been accommodated to properly test this change and the documentation for the API as well.
The custom error types in the provider package did not propagate their wrapped
underlying reasons, making it difficult for the test to check that the correct
error was observed.
- Fix the custom errors to have a true underlying error (not just a string).
- Add Unwrap methods to support inspection by errors.Is.
- Update usage in a few places.
- Fix the test to check for acceptable variation.
Fixes#7609.
After writing and then reading a bunch of random messages, the test was
checking that it did not read the same number of messages that it wrote.
The sense of this check was inverted; they should match.
Introduced by accident in #7522. I'm not sure why this did not show up in CI.
Edit: I now know why it didn't show up in ci: #7608.
Add package jsontypes that implements a subset of the custom libs/json
package. Specifically it handles encoding and decoding of interface types
wrapped in "tagged" JSON objects. It omits the deep reflection on arbitrary
types, preserving only the handling of type tags wrapper encoding.
- Register interface types (Evidence, PubKey, PrivKey) for tagged encoding.
- Update the existing implementations to satisfy the type.
- Register those types with the jsontypes registry.
- Add string tags to 64-bit integer fields where needed.
- Add marshalers to structs that export interface-typed fields.

* Allow nil block ID check in ensureProposalWithTimout
* William's suggestion to get the proposal from the proposer instead of
generating it.
* Remove error check on service stop
This change updates the proposal logic to use the block's timestamp in the proposal message. It adds an additional piece of validation logic to the prevote step to check that the block's timestamp matches the proposal message's timestamp.
This change introduces the logic to have the proposer wait until the previous block time has passed before attempting to propose the next block.
The change achieves this by by adding a new clause into the enterPropose state machine method. The method now checks if the validator is the proposer and if the validator's clock is behind the previous block's time. If the validator's clock is behind the previous block time, it schedules a timeout to re-enter the enter propose method after enough time has passed.
This change adds the new TimingParams proto messages. These new messages were build using the wb/proposer-based-timestamps branch on the spec repo.
This change also adds validation that these values are positive when parsed and adds the new parameters into the existing tests.

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.
The parameters for RPC GET requests are parsed from query arguments in the
request URL. Rework this code to remove the need for tmjson. The structure of a
call still requires reflection, and still works the same way as before, but the
code structure has been simplified and cleaned up a bit.
Points of note:
- Consolidate handling of pointer types, so we only need to dereference once.
- Reduce the number of allocations of reflective types.
- Report errors for unsupported types rather than returning untyped nil.
Update the tests as well. There was one test case that checked for an error on
a behaviour the OpenAPI docs explicitly demonstrates as supported, so I fixed
that test case, and also added some new ones for cases that weren't checked.

Require that RPC functions take a context as their first argument, and return
an error as either their only result, or the second of two results.
This does not change how functions are dispatched, but will make it a little
easier to make more invasive changes in the near future.
Instead of taking a comma-separated string of parameter names, take each
parameter name as a separate argument. Now that we no longer have an extra flag
for caching, this fits nicely into a variadic trailer.
* Update all usage of NewRPCFunc and NewWSRPCFunc.
Define interfaces for the various methods a service may implement. This is
basically just the set of things on Environment that are exported as RPCs, but
these are also implemented by the light proxy.
* internal/rpc: use NewRoutesMap to construct routes on service start
* light/proxy: use NewRoutesMap to construct RPC routes
Rather than installing two separate panic handlers, defer the bookkeeping
separately from recovery, and lift the delegated handler call out to the top
level of the wrapper.
Also: Regularize the server middleware wrappers.
Add writeRPCResponse and writeHTTPResponse helpers, that handle the way RPC
responses are written to HTTP replies. These replace the exported helpers.
Visible effects:
- JSON results are now marshaled without indentation.
- HTTP status codes are now normalized.
- Cache control headers are no longer set.
Details:
- When writing a response to a URL (GET) request, do not marshal the whole
JSON-RPC object into the body, only encode the result or the error object.
This is a user-visible change.
- Do not change the HTTP status code for RPC errors. The RPC error already
reports what went wrong, the HTTP status should only report problems with the
HTTP transaction itself. This is a user-visible change.
- Encode JSON without indentation in POST response bodies. This is mainly cosmetic
but saves quite a bit of response data. Indent is still applied to GET responses to make
life easier for code examples.
- Remove an obsolete TODO about reporting an HTTP error on websocket upgrade.
Nothing needed to change; the upgrader already reports an error.
- Report an HTTP error when starting the server loop fails.
- Improve logging for encoding errors.
- Log less aggressively.
In two cases, we check for the content of an error right after asserting that
no error occurs. Fix the sense of those checks.
In one case, we check that there is no error with the diagnostic "expected
error". It's not clear whether this means "an error was expected" (which is
what I believe) or "we got the expected error". However, given the way the mock
plumbing is set up, the first interpretation seems right.
We should not set cache-control headers on RPC responses. HTTP caching
interacts poorly with resources that are expected to change frequently, or
whose rate of change is unpredictable.
More subtly, all calls to the POST endpoint use the same URL, which means a
cacheable response from one call may actually "hide" an uncacheable response
from a subsequent one. This is less of a problem for the GET endpoints, but
that means the behaviour of RPCs varies depending on which HTTP method your
client happens to use. Websocket requests were already marked statically
uncacheable, adding yet a third combination.
To address this:
- Stop setting cache-control headers.
- Update the tests that were checking for those headers.
- Remove the flags to request cache-control.
Apart from affecting the HTTP response headers, this change does not modify the
behaviour of any of the RPC methods.
Bumps [github.com/BurntSushi/toml](https://github.com/BurntSushi/toml) from 0.4.1 to 1.0.0.
<details>
<summary>Release notes</summary>
<p><em>Sourced from <a href="https://github.com/BurntSushi/toml/releases">github.com/BurntSushi/toml's releases</a>.</em></p>
<blockquote>
<h2>v1.0.0</h2>
<p>This release adds much more detailed errors, support for the <code>toml.Marshaler</code> interface, and several fixes.</p>
<p>There is no special meaning in the jump to v1.0; the 0.x releases were always treated as if they're 1.x with regards to compatibility; the versioning scheme for this library predates the release of modules.</p>
<h2>New features</h2>
<ul>
<li>
<p>Error reporting is much improved; the reported position of errors should now always be correct and the library can print more detailed errors (<a href="https://github-redirect.dependabot.com/BurntSushi/toml/issues/299">#299</a>, <a href="https://github-redirect.dependabot.com/BurntSushi/toml/issues/332">#332</a>)</p>
<p>Decode always return a <code>toml.ParseError</code>, which has three methods:</p>
<ul>
<li>
<p><code>Error()</code> behaves as before and shows a single concise line with the error.</p>
</li>
<li>
<p><code>ErrorWithLocation()</code> shows the same error, but also shows the line the error occurred at, similar to e.g. clang or the Rust compiler.</p>
</li>
<li>
<p><code>ErrorWithUsage()</code> is the same as <code>ErrorWithPosition()</code>, but may also show a longer usage guidance message. This isn't always present (in which case it behaves identical to <code>ErrorWithPosition()</code>), but it should be present for most common mistakes and sources of confusion.</p>
</li>
</ul>
<p>Which error the correct one to use is depends on your application and preferences; in general I would recommend using at least <code>ErrorWithPosition()</code> for user-facing errors, as it's much more helpful for users of any skill level. If your users are likely to be non-technical then <code>ErrorWithUsage()</code> is probably a good idea; I did my best to avoid technical jargon such as "newline" and phrase things in a way that's understandable by most people not intimately familiar with these sort of things.</p>
<p>Additionally, the TOML key that fialed should now always be reported in all errors.</p>
</li>
<li>
<p>Add <code>toml.Marshaler</code> interface. This can be used if you want full control over how something is marshalled as TOML, similar to <code>json.Marshaler</code> etc. This takes precedence over <code>encoding.TextMarshaler</code>. (<a href="https://github-redirect.dependabot.com/BurntSushi/toml/issues/327">#327</a>)</p>
</li>
<li>
<p>Allow TOML integers to be decoded to a Go float (<a href="https://github-redirect.dependabot.com/BurntSushi/toml/issues/325">#325</a>)</p>
<p>Previously <code>int = 42</code> could only be decoded to an <code>int*</code> type; now this can also be decoded in a <code>float</code> type as long as it can be represented without loss of data.</p>
</li>
</ul>
<h2>Fixes</h2>
<ul>
<li>
<p>Key.String() is now quoted when needed (<a href="https://github-redirect.dependabot.com/BurntSushi/toml/issues/333">#333</a>)</p>
</li>
<li>
<p>Fix decoding of nested structs on 32bit platforms (<a href="https://github-redirect.dependabot.com/BurntSushi/toml/issues/314">#314</a>)</p>
</li>
<li>
<p>Empty slices are now always <code>[]T{}</code> rather than nil, which was the behaviour in v0.3.1 and before. While they are identical for most purposes, encoding/json encodes them different (<code>[]</code> vs. <code>null</code>), making it an (accidentally) incompatible change (<a href="https://github-redirect.dependabot.com/BurntSushi/toml/issues/339">#339</a>)</p>
</li>

* Rename rpctypes.Context to CallInfo.

No functional changes.
- Pull out a some helper code to simplify the control flow within the body of
the HTTP request handler.
- Front-load the URL path check so it does not get repeated for each request.
Instead of using anonymous maps, define tagged struct types for JSON argument
encoding. This allows us to have the encoding rules we want without tmjson.
This commit handles the "easy" cases. BroadcastEvidence is omitted here,
because it depends on the interface encoding rules from tmjson. I will address
that in a forthcoming change.
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
* Update Caller interface and its documentation.
* Rework MapToRequest as ParamsToRequest.
The old interface returned the result as well as populating it. Nothing was
using this, so drop the duplicated value from the return signature. Clarify the
documentation on the Caller type.
Rework the MapToRequest helper to take an arbitrary value instead of only a
map. This is groundwork for getting rid of the custom marshaling code. For now,
however, the implementation preserves the existing behaviour for the map, until
we can replace those.
These two interfaces are identical, and besides HTTPClient being confusingly
named, all but one location uses Caller. Update that one location, and drop the
redundant interface.
Apart from the tests for the websocket client, positional parameters are not
used by RPC clients. The server supports both arrays and objects, but the
client only needs to provide one or the other.
Where possible, replace uses of the custom JSON library with the standard
library. The custom library treats interface and unnamed lteral types
differently, so this change avoids those even where it would probably be safe
to switch them.
These tests use a deterministic and unseeded random source to generate
non-colliding filenames for testing. When testing locally, this means tests are
not hermetic from one run to the next.
Use proper temp directories, and clean up after they're done.

The JSON-RPC endpoint accepts requests via URL (GET) and JSON (POST). There is
no real point in having client libraries for both modes.
A search of the SDK and on GitHub suggests that most usage is via the JSON
client (via the New constructor) or websocket (NewWS), and the only uses I
found of the NewURI client constructor are in copies of our own test code.
This does not change the functionalitiy of the server, so curl and other
URL-based clients in other languages will still function as before.

Noticed in profiles that invoking *VoteSignBytes always created a
bytes.Buffer, then discarded it inside protoio.MarshalDelimited.
I dug further and examined the call paths and noticed that we
unconditionally create the bytes.Buffer, even though we might
have proto messages (in the common case) that implement
MarshalTo([]byte), and invoked varintWriter. Instead by inlining
this case, we skip a bunch of allocations and CPU cycles,
which then reflects properly on all calling functions. Here
are the benchmark results:
```shell
$ benchstat before.txt after.txt
name old time/op new time/op delta
types.VoteSignBytes-8 705ns ± 3% 573ns ± 6% -18.74% (p=0.000 n=18+20)

Per https://blog.mergify.com/strict-mode-deprecation/, the strict mode
has been deprecated and will be turned off on 10-Jan-2022. This updates
the config to use the new, approved thing instead of the old thing.
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.
The current testing for this tool relies on hardcoding a set of configs into the tests. This means that when the config structure changes, the tests break. I'm not sure that this makes sense since we are separately testing our ability to read and validate the configuration file format. Hardcoding bytes into a different file duplicates this. Using the structs themselves should therefore be preferred.
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.
Prior to this change, shutting down the pubsub server could cause
any laggard publishers to race with the shutdown plumbing.
Fix that race condition, and plumb in the service context to the
runner so that it will respect the external signal directly.
Remove now-redundant local shutdown plumbing.

Rework the implementation of event query parsing and execution to
improve performance and reduce memory usage.
Previous memory and CPU profiles of the pubsub service showed query
processing as a significant hotspot. While we don't have evidence that
this is visibly hurting users, fixing it is fairly easy and self-contained.
Updates #6439.
Typical benchmark results comparing the original implementation (PEG) with the reworked implementation (Custom):
```
TEST TIME/OP BYTES/OP ALLOCS/OP SPEEDUP MEM SAVING
BenchmarkParsePEG-12 51716 ns 526832 27
BenchmarkParseCustom-12 2167 ns 4616 17 23.8x 99.1%
BenchmarkMatchPEG-12 3086 ns 1097 22
BenchmarkMatchCustom-12 294.2 ns 64 3 10.5x 94.1%
```
Components:
* Add a basic parsing benchmark.
* Move the original query implementation to a subdirectory.
* Add lexical scanner for Query expressions.
* Add a parser for Query expressions.
* Implement query compiler.
* Add test cases based on OpenAPI examples.
* Add MustCompile to replace the original MustParse, and update usage.
The event examples for the query filter language were not updated after the
change of key and value types from []byte to string. Also, the attributes need
to be a slice not a bare value.
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.
Since the doc site is built from the backport branches, the config changes for
a new major release also need to be replicated into the backport branch as well
as master. Update the release docs to mention that specifically, since I missed
it during the v0.35 release.
This pull request updates the `protocgen.sh` script to insert the `go_package` option to all of the downloaded proto files. A related pull request into the spec repo removes this options from the .proto files: https://github.com/tendermint/spec/pull/358
This pull requests, along with the related spec PR, aim to move the creation of the `tendermintdev/docker-build-proto` container into the spec repo. This change also relies on several fixes to that container that are made in the PR into the spec repo.
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.
* update the proposer-based timestamps spec per discussion with @cason
* add vote to list of changed structs
* sentence fix
* clarify crypto sig logic update
* language updates per feedback from @cason
* fix POL < 0 wording
* update timely description for non-polka
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
This pull request adds a new "mesage_type" label to the send/recv bytes metrics calculated in the p2p code.
Below is a snippet of the updated metrics that includes the updated label:
```
tendermint_p2p_peer_receive_bytes_total{chID="32",chain_id="ci",message_type="consensus_HasVote",peer_id="2551a13ed720101b271a5df4816d1e4b3d3bd133"} 652

```
Rework the internal plumbing of the server. This change does not modify the
exported interfaces or semantics of the package, and all the existing tests
still pass.
The main changes here are to:
- Simplify the interface for subscription indexing with a typed index rather
than a single nested map.
- Ensure orderly shutdown of channels, so that there is no longer a dynamic
race with concurrent publishers & subscribers at shutdown.
- Remove a layer of indirection between publishers and subscribers. This mainly
helps legibility.
- Remove order dependencies between registration and delivery.
- Add documentation comments where they seemed helpful, and clarified the
existing comments where it was practical.
Although performance was not a primary goal of this change, the simplifications
did very slightly reduce memory use and increase throughput on the existing
benchmarks, though the delta is not statistically significant.

This pull request fixes a panic that exists in both mempools. The panic occurs when the ABCI client misses a response from the ABCI application. This happen when the ABCI client drops the request as a result of a full client queue. The fix here was to loop through the ordered list of recheck-tx in the callback until one matches the currently observed recheck request.
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.
This patch was needed to pass the buf breakage check for the proto file removed
in #7121, but now that master contains the change we no longer need the patch.
This change removes the partial gRPC interface to the RPC service, which was
deprecated in resolution of #6718.
Details:
- rpc: Remove the client and server interfaces and proto definitions.
- Remove the gRPC settings from the config library.
- Remove gRPC setup for the RPC service in the node startup.
- Fix various test helpers to remove gRPC bits.
- Remove the --rpc.grpc-laddr flag from the CLI.
Note that to satisfy the protobuf interface check, this change also includes a
temporary edit to buf.yaml, that I will revert after this is merged.
This metric describes itself as 'pending' but never actual decrements when the messages are removed from the queue.
This change fixes that by decrementing the metric when the data is removed from the queue.
This PR adds an initial set of metrics for use ABCI. The initial metrics enable the calculation of timing histograms and call counts for each of the ABCI methods. The metrics are also labeled as either 'sync' or 'async' to determine if the method call was performed using ABCI's `*Async` methods.
An example of these metrics is included here for reference:

```
These metrics can easily be graphed using prometheus's `histogram_quantile(...)` method to pick out a particular quantile to graph or examine. I chose buckets that were somewhat of an estimate of expected range of times for ABCI operations. They start at .0001 seconds and range to 25 seconds. The hope is that this range captures enough possible times to be useful for us and operators.
Fixes#7068. The build-docker rule relies on being able to run make
build-linux, but did not pull the Makefile into the build context.
There are various ways to fix this, but this was probably the smallest.
Fixes#7098. The light client documentation moved to the spec repository.
I was not able to figure out what happened to light-client-protocol.md, it was removed in #5252 but no corresponding file exists in the spec repository. Since the spec also discusses the protocol, this change simply links to the spec and removes the non-functional reference.
Alternatively we could link to the top-level [light client doc](https://docs.tendermint.com/master/tendermint-core/light-client.html) if you think that's better.
This tweaks the connectivity of test configurations, in hopes that more will be viable.
Additionally reduces the prevalence of testing the legacy mempool.
My earlier p2p cleanup code removed support for the p2p tests from the
e2e generator and runner, but missed removing the CI
configuration. This patch remedies that.
While discussing a question about the indexing interface (#7044), we found some
confusion about the intent of the design decisions in ADR 065.
Based on discussion with the original authors of the ADR, this commit adds some
language to the Decisions section to spell out the intentions more clearly, and
to call out future work that this ADR did not explicitly decide about.
Addresses one of the concerns with #7041.
Provides a mechanism (via the RPC interface) to delete a single transaction, described by its hash, from the mempool. The method returns an error if the transaction cannot be found. Once the transaction is removed it remains in the cache and cannot be resubmitted until the cache is cleared or it expires from the cache.
This code hasn't been battle tested, and seems to have grown
increasingly flaky int tests. Given our general direction of reducing
queue complexity over the next couple of releases I think it makes
sense to remove it.
This PR tackles the case of using the e2e application in a long lived testnet. The application continually saves snapshots (usually every 100 blocks) which after a while bloats the size of the application. This PR prunes older snapshots so that only the most recent 10 snapshots remain.
A few notes:
- this is not all the deletion that we can do, but this is the most
"simple" case: it leaves in shims, and there's some trivial
additional cleanup to the transport that can happen but that
requires writing more code, and I wanted this to be easy to review
above all else.
- This should land *after* we cut the branch for 0.35, but I'm
anticipating that to happen soon, and I wanted to run this through
CI.
The race occurred as a result of a goroutine launched by `processPeerUpdate` racing with the `OnStop` method. The `processPeerUpdates` goroutine deletes from the map as `OnStop` is reading from it. This change updates the `OnStop` method to wait for the peer updates channel to be done before closing the peers. It also copies the map contents to a new map so that it will not conflict with the view of the map that the goroutine created in `processPeerUpdate` sees.
This commit should be one of the first to land as part of the v0.36
cycle *after* cutting the 0.35 branch.
The blocksync/v2 reactor was originally implemented as an experiement
to produce an implementation of the blockstack protocol that would be
easier to test and validate, but it was never appropriately
operationalized and this implementation was never fully debugged. When
the p2p layer was refactored as part of the 0.35 cycle, the v2
implementation was not refactored and it was left in the codebase but
not removed. This commit just removes all references to it.
This script is referenced from the release documentation, we should make sure it's functional. This is helpful in generating the "Special Thanks" section of the changelog.
This is intended to fix a test failure that occurs in the p2p state provider. The issue presents as the state provider timing out waiting for the consensus params response.
The reason that this can occur is because the statesync reactor has the possibility of attempting to respond to the params request before the state provider is ready to read it. This results in the reactor hitting the `default` case seen here and then never sending on the channel. The stateprovider will then block waiting for a response and never receive one because the reactor opted not to send it.
When statesync is stopped during shutdown, it has the possibility of deadlocking. A dump of goroutines reveals that this is related to the peerUpdates channel not returning anything on its `Done()` channel when `OnStop` is called. As this is occuring, `processPeerUpdate` is attempting to acquire the reactor lock. It appears that this lock can never be acquired. I looked for the places where the lock may remain locked accidentally and cleaned them up in hopes to eradicate the issue. Dumps of the relevant goroutines may be found below. Note that the line numbers below are relative to the code in the `v0.35.0-rc1` tag.

When shutting down blocksync, it is observed that the process can hang completely. A dump of running goroutines reveals that this is due to goroutines not listening on the correct shutdown signal. Namely, the `poolRoutine` goroutine does not wait on `pool.Quit`. The `poolRoutine` does not receive any other shutdown signal during `OnStop` becuase it must stop before the `r.closeCh` is closed. Currently the `poolRoutine` listens in the `closeCh` which will not close until the `poolRoutine` stops and calls `poolWG.Done()`.
This change also puts the `requestRoutine()` in the `OnStart` method to make it more visible since it does not rely on anything that is spawned in the `poolRoutine`.

This test reliably gets hung up on network configuration, (which may
be a real issue,) but it's network setup is handcranked and we should
ensure that the test focuses on it's core assertions and doesn't fail for
test architecture reasons.
Fix the order of lines in docs/versions so that v0.34 is last (the current release).
Related changes:

- Fix the Makefile rule to not clobber package-lock.json.
I observed a couple of problems with the generator in some recent tests:
- there were a couple of hybrid test cases which did not have any
legacy nodes (randomness and all.) I change the probability to
produce more reliable results.
- added options to the generation to be able to add a max (to
compliment the earlier min) number of nodes for local testing.
- added an option to support reversing the sort order so "more
complex" networks were first, as well as tweaked some of the point
values.
- this refactored the generators cli parsing to be a bit more clear.
The main effect of this change is to flush the socket client and server message
encoding buffers immediately once the message is fully and correctly encoded.
This allows us to remove the timer and some other special cases, without
changing the observed behaviour of the system.
-- Background
The socket protocol client and server each use a buffered writer to encode
request and response messages onto the underlying connection. This reduces the
possibility of a single message being split across multiple writes, but has the
side-effect that a request may remain buffered for some time.
The implementation worked around this by keeping a ticker that occasionally
triggers a flush, and by flushing the writer in response to an explicit request
baked into the client/server protocol (see also #6994).
These workarounds are both unnecessary: Once a message has been dequeued for
sending and fully encoded in wire format, there is no real use keeping all or
part of it buffered locally. Moreover, using an asynchronous process to flush
the buffer makes the round-trip performance of the request unpredictable.
-- Benchmarks
Code: https://play.golang.org/p/0ChUOxJOiHt
I found no pre-existing performance benchmarks to justify the flush pattern,
but a natural question is whether this will significantly harm client/server
performance. To test this, I implemented a simple benchmark that transfers
randomly-sized byte buffers from a no-op "client" to a no-op "server" over a
Unix-domain socket, using a buffered writer, both with and without explicit
flushes after each write.
As the following data show, flushing every time (FLUSH=true) does reduce raw
throughput, but not by a significant amount except for very small request
sizes, where the transfer time is already trivial (1.9μs). Given that the
client is calibrated for 1MiB transactions, the overhead is not meaningful.
The percentage in each section is the speedup for flushing only when the buffer
is full, relative to flushing every block. The benchmark uses the default
buffer size (4096 bytes), which is the same value used by the socket client and
server implementation:
FLUSH NBLOCKS MAX AVG TOTAL ELAPSED TIME/BLOCK
false 3957471 512 255 1011165416 2.00018873s 505ns
true 1068568 512 255 273064368 2.000217051s 1.871µs

true 2083 1048576 526379 1096449173 2.001817137s 961.025µs
(1.5%)
Note also that the FLUSH=false baseline is actually faster than the production
code, which flushes more often than is required by the buffer filling up.
Moreover, the timer slows down the overall transaction rate of the client and
server, indepenedent of how fast the socket transfer is, so the loss on a real
workload is probably much less.
I've been noticing that there are a number of situations where the
statesync reactor blocks waiting for peers (or similar,) I've moved
things around to improve outcomes in local tests.
In the last run, there were two problems at the RPC layer returned
from light nodes' RPC end points. I think exercising the light client
proxy RPC system is something that can/should be done via unit
testing, and that likely these errors are (in production) transient
and (in CI) very likely to fail for test environment issues.
The code in the Tendermint repository makes heavy use of import aliasing.
This is made necessary by our extensive reuse of common base package names, and
by repetition of similar names across different subdirectories.
Unfortunately we have not been very consistent about which packages we alias in
various circumstances, and the aliases we use vary. In the spirit of the advice
in the style guide and https://github.com/golang/go/wiki/CodeReviewComments#imports,
his change makes an effort to clean up and normalize import aliasing.
This change makes no API or behavioral changes. It is a pure cleanup intended
o help make the code more readable to developers (including myself) trying to
understand what is being imported where.
Only unexported names have been modified, and the changes were generated and
applied mechanically with gofmt -r and comby, respecting the lexical and
syntactic rules of Go. Even so, I did not fix every inconsistency. Where the
changes would be too disruptive, I left it alone.
The principles I followed in this cleanup are:
- Remove aliases that restate the package name.
- Remove aliases where the base package name is unambiguous.
- Move overly-terse abbreviations from the import to the usage site.
- Fix lexical issues (remove underscores, remove capitalization).
- Fix import groupings to more closely match the style guide.
- Group blank (side-effecting) imports and ensure they are commented.
- Add aliases to multiple imports with the same base package name.
We moved some files further down in the directory structure in #6964, which
caused the relative paths to the mockery wrapper to stop working.
There does not seem to be an obvious way to get the module root as a default
environment variable, so for now I just added the extra up-slashes.
This package is not used in the tendermint repository since 31e7cdee.
Note that this is not the same package as rpc/client/mock (N.B. singular) which
is still used in some tests.
A search of GitHub turns up only 11 uses, all of which are in clones of the
tendermint repo at old commits..
* rpc: Strip down the base RPC client interface.
Prior to this change, the RPC client interface requires implementing the entire
Service interface, but most of the methods of Service are not needed by the
concrete clients. Dissociate the Client interface from the Service interface.
- Extract only those methods of Service that are necessary to make the existing
clients work.
- Update the clients to combine Start/Onstart and Stop/OnStop. This does not
change what the clients do to start or stop. Only the websocket clients make
use of this functionality anyway.
The websocket implementation uses some plumbing from the BaseService helper.
We should be able to excising that entirely, but the current interface
dependencies among the clients would require a much larger change, and one
that leaks into other (non-RPC) packages.
As a less-invasive intermediate step, preserve the existing client behaviour
(and tests) by extracting the necessary subset of the BaseService
functionality to an analogous RunState helper for clients. I plan to obsolete
that type in a future PR, but for now this makes a useful waypoint.

## Description
- Add deprecated to config values in toml
- update config in configuration doc
- explain how to set up a node with the new network
- add sentence about not needing to fork tendermint for built-in tutorial
- closes#6865
- add note to use a released version of tendermint with the tutorials. This is to avoid unknown issues prior to a release.
If the e2e tests error, they leave all of the e2e state around including containers and networks etc.
We should clean this up when the tests shuts down, even if it exits in error.
This should address last night's failure. We've taken the perspective
of "the load generator shouldn't cause tests to fail" in recent
days/weeks, and I think this is just a next step along that line. The
e2e tests shouldn't test performance.
I included some comments indicating the ways that this isn't ideal (it
is perhaps not), and I think that if test networks could make
assertions about the required rate, that might be a cool future
improvement (and good, perhaps, for system benchmarking.)
This document attempts to capture and discuss some of the areas of Tendermint that seem to be cited as causing performance issue. I'm hoping to continue to gather feedback and input on this document to better understand what issues Tendermint performance may cause for our users.
The overall goal of this document is to allow the maintainers and community to get a better sense of these issues and to be more capably able to discuss them and weight trade-offs about any proposed performance-focused changes. This document does not aim to propose any performance improvements. It does suggest useful places for benchmarks and places where additional metrics would be useful for diagnosing and further understanding Tendermint performance.
Please comment with areas where my reasoning seems off or with additional areas that Tendermint performance may be causing user pain.
I think the `Sync` check covers our primary use case, and perhaps we
can turn this back on in the future after some kind of event-system
rewrite, or RPC rewrite that will avoid the serverside timeout.
These are mostly the timeouts that I think we're still hitting in CI.
At this point, the tests (on master) pass on my local machine (which is quite beefy) so I think this is just the first in (perhaps?) a sequence of changes that attempt to change timeouts and load patterns so that the tests pass in CI more reliably.
Communication in Tendermint among consensus nodes, applications, and operator
tools all use different message formats and transport mechanisms. In some
cases there are multiple options. Having all these options complicates both the
code and the developer experience, and hides bugs. To support a more robust,
trustworthy, and usable system, we should document which communication paths
are essential, which could be removed or reduced in scope, and what we can
improve for the most important use cases.
This document proposes a variety of possible improvements of varying size and
scope. Specific design proposals should get their own documentation.
The previous implemention of hybrid set testing, which was entirely my
own creation, was a bit peculiar, and I think this probably clears thins up.
The previous implementation had far fewer legacy nodes in hybrid
networks, *and* also for some reason that I can't quite explain,
caused a test case to fail.

The responses from node RPCs encode hash values as hexadecimal strings. This
behaviour is stipulated in our OpenAPI documentation. In some cases, however,
hashes received as JSON parameters were being decoded as byte buffers, as is
the convention for JSON.
This resulted in the confusing situation that a hash reported by one request
(e.g., broadcast_tx_commit) could not be passed as a parameter to another
(e.g., tx) via JSON, without translating the hex-encoded output hash into the
base64 encoding used by JSON for opaque bytes.
Fixes#6802.
The 0.35 release cycle renamed the 'fastsync' functionality to 'blocksync'. This change brings the configuration parameters in line with that change. Namely, it updates the configuration file `[fastsync]` field to be `[blocksync]` and changes the command line flag and config file parameters `--fast-sync` and `fast-sync` to `--enable-block-sync` and `enable-block-sync` respectively.
Error messages were added to help users encountering these changes be able to quickly make the needed update to their files/scripts.
When using the old command line argument for fast-sync, the following is printed
```
./build/tendermint start --proxy-app=kvstore --consensus.create-empty-blocks=false --fast-sync=false
ERROR: invalid argument "false" for "--fast-sync" flag: --fast-sync has been deprecated, please use --enable-block-sync
```
When using one of the old config file parameters, the following is printed:
```
./build/tendermint start --proxy-app=kvstore --consensus.create-empty-blocks=false
ERROR: error in config file: a configuration parameter named 'fast-sync' was found in the configuration file. The 'fast-sync' parameter has been renamed to 'enable-block-sync', please update the 'fast-sync' field in your configuration file to 'enable-block-sync'
```
* add information on upgrading to the new p2p library

* fix spacing in upgrading
This is a cosmetic change that restores lexicographic order to the selected
linters in the CI config. No change to which linters we run, only putting them
back in order so it's easier to spot the one you care about.
This changes the focus of the e2e suite, to (roughly) focus on
configurations that are more well used. Most production users of
tendermint run ABCI application in process and the GRPC/socket methods
cover the vast majority of the remaining use cases.
Perhaps we should consider drop support unix domain sockets in a
future release, but I think in the mean time it's useful to have the
tests *mostly* focus on the primary use cases.
Update the schema and implementation of the Postgres event indexer to improve
certain types of queries against the index. These changes address the use cases
raised by #6843, and are partly inspired by the prototype schema in that issue.
In the old schema, events were flattened, making it difficult to find all the events
associated with a particular block or transaction. In addition, events with no key/value
attributes were entirely lost, since entries were generated only for attributes.
To address these issues, this new schema records blocks, transactions, events,
and attributes in separate tables, and provides views that join these tables to
give a more convenient query surface for block and transaction events.
- All events for a given block can be queried from the `block_events` view.
- All events for a given transaction can be queried from the `tx_events` view.
- Multiple events for the same key can be indexed for both blocks and transactions.
The tests have been reworked, but all of the existing test cases for the old schema
still pass with the new implementation. Various other minor cleanups are included,
ADR-065 is also updated to reflect the updated schema.
An explicit exit prevents the deferred cleanup code from running. In this case,
falling off the end of main will achieve the same goal as an explicit exit.
When revwing #6807 I assumed that `probSetChoice` worked this way.
I think that the coverage of various configuration options should
generally track what we expect the actual useage to be to focus the
most test coverage on the configurations that are the most prevelent.
Issues reported in Osmosis, where the message is extremely long. Also, there is absolutely no reason to log the message IMO. If we must, we can make the message log DEBUG.
This is just a configuration change to default to using the new stack
unless explicitly disabled (e.g. `UseLegacy`) this renames the
configuration value and makes the configuration logic more clear.
The legacy option is good to retain as a fallback if the new stack has
issues operationally, but we should make sure that most of the time
we're using the new stack.
In the transaction load generator, the e2e test harness previously distributed load randomly to hosts, which was a source of test non-determinism. This change distributes the load generation to the different nodes in the set in a round robin fashion, to produce more reliable results, but does not otherwise change the behavior of the test harness.
Add documentation comments to the psql event sink package, and simplify the
constructor function so that it does not return the SQL database handle. The
handle is needed for testing, so expose that via a separate method on the
concrete type.
Update the tests and existing usage for the change. This change does not affect
the behaviour of the sink, so there are no functional changes, only syntactic
updates.
EDIT: Updated, see [comment below]( https://github.com/tendermint/tendermint/pull/6785#issuecomment-897793175)
This change adds a sketch of the `Debug` mode.
This change adds a `Debug` struct to the node package. This `Debug` struct is intended to be created and started by a command in the `cmd` directory. The `Debug` struct runs the RPC server on the data directories: both the state store and the block store.
This change required a good deal of refactoring. Namely, a new `rpc.go` file was added to the `node` package. This file encapsulates functions for starting RPC servers used by nodes. A potential additional change is to further factor this code into shared code _in_ the `rpc` package.
Minor API tweaks were also made that seemed appropriate such as the mechanism for fetching routes from the `rpc/core` package.
Additional work is required to register the `Debug` service as a command in the `cmd` directory but I am looking for feedback on if this direction seems appropriate before diving much further.
closes: #5908
This is a very minor change, but I was looking through the code, and
this seems like it shouldn't be exported or used more broadly, so I've
moved it out.
This ADR restores a variation of the old Request for Comments documentation
that we previously used. The proposal differs from the original formulation,
and does not replace ADRs.

- [mempool] [\#6466](https://github.com/tendermint/tendermint/pull/6466) Introduction of a prioritized mempool. (@alexanderbez)
-`Priority` and `Sender` have been introduced into the `ResponseCheckTx` type, where the `priority` will determine the prioritization of
the transaction when a proposer reaps transactions for a block proposal. The `sender` field acts as an index.
- Operators may toggle between the legacy mempool reactor, `v0`, and the new prioritized reactor, `v1`, by setting the
`mempool.version` configuration, where `v1` is the default configuration.
- Applications that do not specify a priority, i.e. zero, will have transactions reaped by the order in which they are received by the node.
- Transactions are gossiped in FIFO order as they are in `v0`.

### FEATURES
- [config] Add `--mode` flag and config variable. See [ADR-52](https://github.com/tendermint/tendermint/blob/master/docs/architecture/adr-052-tendermint-mode.md) @dongsam
- [rpc] \#6329 Don't cap page size in unsafe mode (@gotjoshua, @cmwaters)
- [pex] \#6305 v2 pex reactor with backwards compatability. Introduces two new pex messages to
accomodate for the new p2p stack. Removes the notion of seeds and crawling. All peer
exchange reactors behave the same. (@cmwaters)
- [crypto] \#6376 Enable sr25519 as a validator key
- [mempool] \#6466 Introduction of a prioritized mempool. (@alexanderbez)
-`Priority` and `Sender` have been introduced into the `ResponseCheckTx` type, where the `priority` will determine the prioritization of
the transaction when a proposer reaps transactions for a block proposal. The `sender` field acts as an index.
- Operators may toggle between the legacy mempool reactor, `v0`, and the new prioritized reactor, `v1`, by setting the
`mempool.version` configuration, where `v1` is the default configuration.
- Applications that do not specify a priority, i.e. zero, will have transactions reaped by the order in which they are received by the node.
- Transactions are gossiped in FIFO order as they are in `v0`.
- [config/indexer] \#6411 Introduce support for custom event indexing data sources, specifically PostgreSQL. (@JayT106)
- [fastsync/event] \#6619 Emit fastsync status event when switching consensus/fastsync (@JayT106)
- [statesync/event] \#6700 Emit statesync status start/end event (@JayT106)
- [cli] [#7033](https://github.com/tendermint/tendermint/pull/7033) Add a `rollback` command to rollback to the previous tendermint state in the event of non-determinstic app hash or reverting an upgrade.
- [mempool, rpc] \#7041 Add removeTx operation to the RPC layer. (@tychoish)
- [consensus] \#7354 add a new `synchrony` field to the `ConsensusParameter` struct for controlling the parameters of the proposer-based timestamp algorithm. (@williambanfield)
- [consensus] \#7376 Update the proposal logic per the Propose-based timestamps specification so that the proposer will wait for the previous block time to occur before proposing the next block. (@williambanfield)
- [consensus] \#7391 Use the proposed block timestamp as the proposal timestamp. Update the block validation logic to ensure that the proposed block's timestamp matches the timestamp in the proposal message. (@williambanfield)
- [consensus] \#7415 Update proposal validation logic to Prevote nil if a proposal does not meet the conditions for Timelyness per the proposer-based timestamp specification. (@anca)
-[consensus] \#7382 Update block validation to no longer require the block timestamp to be the median of the timestamps of the previous commit. (@anca)
### IMPROVEMENTS
- [libs/log] Console log formatting changes as a result of \#6534 and \#6589. (@tychoish)
- [statesync] \#6566 Allow state sync fetchers and request timeout to be configurable. (@alexanderbez)
- [types] \#6478 Add `block_id` to `newblock` event (@jeebster)
- [cli] \#5772 `gen_node_key` output now contains node ID (`id` field) (@melekes)
- [blockchain/v2] \#5774 Send status request when new peer joins (@melekes)
- [consensus] \#5792 Deprecates the `time_iota_ms` consensus parameter, to reduce the bug surface. The parameter is no longer used. (@valardragon)
- [store] \#5888 store.SaveBlock saves using batches instead of transactions for now to improve ACID properties. This is a quick fix for underlying issues around tm-db and ACID guarantees. (@githubsands)
- [consensus] \#5987 Remove `time_iota_ms` from consensus params. Merge `tmproto.ConsensusParams` and `abci.ConsensusParams`. (@marbar3778)
- [types] \#5994 Reduce the use of protobuf types in core logic. (@marbar3778)
-`ConsensusParams`, `BlockParams`, `ValidatorParams`, `EvidenceParams`, `VersionParams`, `sm.Version` and `version.Consensus` have become native types. They still utilize protobuf when being sent over the wire or written to disk.
- [rpc/client/http] \#6163 Do not drop events even if the `out` channel is full (@melekes)
- [node] \#6059 Validate and complete genesis doc before saving to state store (@silasdavis)
- [state] \#6067 Batch save state data (@githubsands&@cmwaters)
- [crypto] \#6120 Implement batch verification interface for ed25519 and sr25519. (@marbar3778)
- [types] \#6120 use batch verification for verifying commits signatures.
- If the key type supports the batch verification API it will try to batch verify. If the verification fails we will single verify each signature.
- [privval/file] \#6185 Return error on `LoadFilePV`, `LoadFilePVEmptyState`. Allows for better programmatic control of Tendermint.
- [privval] \#6240 Add `context.Context` to privval interface.
- [rpc] \#6265 set cache control in http-rpc response header (@JayT106)
- [statesync] \#6378 Retry requests for snapshots and add a minimum discovery time (5s) for new snapshots.

Each PR should have one commit once it lands on `master`; this can be accomplished by using the "squash and merge" button on Github. Be sure to edit your commit message, though!
### Release procedure
#### A note about backport branches
Tendermint's `master` branch is under active development.
Releases are specified using tags and are built from long-lived "backport" branches.
Each release "line" (e.g. 0.34 or 0.33) has its own long-lived backport branch,
and the backport branches have names like `v0.34.x` or `v0.33.x`
(literally, `x`; it is not a placeholder in this case).
As non-breaking changes land on `master`, they should also be backported (cherry-picked)
to these backport branches.
We use Mergify's [backport feature](https://mergify.io/features/backports) to automatically backport
to the needed branch. There should be a label for any backport branch that you'll be targeting.
To notify the bot to backport a pull request, mark the pull request with
the label `S:backport-to-<backport_branch>`.
Once the original pull request is merged, the bot will try to cherry-pick the pull request
to the backport branch. If the bot fails to backport, it will open a pull request.
The author of the original pull request is responsible for solving the conflicts and
merging the pull request.
#### Creating a backport branch
If this is the first release candidate for a major release, you get to have the honor of creating
the backport branch!
Note that, after creating the backport branch, you'll also need to update the tags on `master`
so that `go mod` is able to order the branches correctly. You should tag `master` with a "dev" tag
that is "greater than" the backport branches tags. See #6072 for more context.
In the following example, we'll assume that we're making a backport branch for
the 0.35.x line.
1. Start on `master`
2. Create the backport branch:
`git checkout -b v0.35.x`
3. Go back to master and tag it as the dev branch for the _next_ major release and push it back up:
`git tag -a v0.36.0-dev; git push v0.36.0-dev`
4. Create a new workflow to run the e2e nightlies for this backport branch.
(See https://github.com/tendermint/tendermint/blob/master/.github/workflows/e2e-nightly-34x.yml
for an example.)
#### Release candidates
Before creating an official release, especially a major release, we may want to create a
release candidate (RC) for our friends and partners to test out. We use git tags to
create RCs, and we build them off of backport branches.
Tags for RCs should follow the "standard" release naming conventions, with `-rcX` at the end
(for example, `v0.35.0-rc0`).
(Note that branches and tags _cannot_ have the same names, so it's important that these branches
have distinct names from the tags/release names.)
If this is the first RC for a major release, you'll have to make a new backport branch (see above).
Otherwise:
1. Start from the backport branch (e.g. `v0.35.x`).
1. Run the integration tests and the e2e nightlies
- Move the changes included in `CHANGELOG_PENDING.md` into `CHANGELOG.md`.
- Run `python ./scripts/linkify_changelog.py CHANGELOG.md` to add links for
all PRs
- Ensure that UPGRADING.md is up-to-date and includes notes on any breaking changes
or other upgrading flows.
- Bump TMVersionDefault version in `version.go`
- Bump P2P and block protocol versions in `version.go`, if necessary
- Bump ABCI protocol version in `version.go`, if necessary
1. Open a PR with these changes against the backport branch.
1. Once these changes have landed on the backport branch, be sure to pull them back down locally.
2. Once you have the changes locally, create the new tag, specifying a name and a tag "message":
`git tag -a v0.35.0-rc0 -m "Release Candidate v0.35.0-rc0`
3. Push the tag back up to origin:
`git push origin v0.35.0-rc0`
Now the tag should be available on the repo's releases page.
4. Future RCs will continue to be built off of this branch.
Note that this process should only be used for "true" RCs--
release candidates that, if successful, will be the next release.
For more experimental "RCs," create a new, short-lived branch and tag that instead.
#### Major release
This major release process assumes that this release was preceded by release candidates.
If there were no release candidates, begin by creating a backport branch, as described above.
1. Start on the backport branch (e.g. `v0.35.x`)
2. Run integration tests and the e2e nightlies.
3. Prepare the release:
- "Squash" changes from the changelog entries for the RCs into a single entry,
and add all changes included in `CHANGELOG_PENDING.md`.
(Squashing includes both combining all entries, as well as removing or simplifying
any intra-RC changes. It may also help to alphabetize the entries by package name.)
- Run `python ./scripts/linkify_changelog.py CHANGELOG.md` to add links for
all PRs
- Ensure that UPGRADING.md is up-to-date and includes notes on any breaking changes
or other upgrading flows.
- Bump TMVersionDefault version in `version.go`
- Bump P2P and block protocol versions in `version.go`, if necessary
- Bump ABCI protocol version in `version.go`, if necessary
- Add any release notes you would like to be added to the body of the release to `release_notes.md`.
4. Open a PR with these changes against the backport branch.
5. Once these changes are on the backport branch, push a tag with prepared release details.
This will trigger the actual release `v0.35.0`.
-`git tag -a v0.35.0 -m 'Release v0.35.0'`
-`git push origin v0.35.0`
7. Make sure that `master` is updated with the latest `CHANGELOG.md`, `CHANGELOG_PENDING.md`, and `UPGRADING.md`.
#### Minor release (point releases)
Minor releases are done differently from major releases: They are built off of long-lived backport branches, rather than from master.
As non-breaking changes land on `master`, they should also be backported (cherry-picked) to these backport branches.
Minor releases don't have release candidates by default, although any tricky changes may merit a release candidate.
To create a minor release:
1. Checkout the long-lived backport branch: `git checkout v0.35.x`
2. Run integration tests (`make test_integrations`) and the nightlies.
3. Check out a new branch and prepare the release:
- Copy `CHANGELOG_PENDING.md` to top of `CHANGELOG.md`
- Run `python ./scripts/linkify_changelog.py CHANGELOG.md` to add links for all issues
- Run `bash ./scripts/authors.sh` to get a list of authors since the latest release, and add the GitHub aliases of external contributors to the top of the CHANGELOG. To lookup an alias from an email, try `bash ./scripts/authors.sh <email>`
- Reset the `CHANGELOG_PENDING.md`
- Bump the ABCI version number, if necessary.
(Note that ABCI follows semver, and that ABCI versions are the only versions
which can change during minor releases, and only field additions are valid minor changes.)
- Add any release notes you would like to be added to the body of the release to `release_notes.md`.
4. Open a PR with these changes that will land them back on `v0.35.x`
5. Once this change has landed on the backport branch, make sure to pull it locally, then push a tag.
-`git tag -a v0.35.1 -m 'Release v0.35.1'`
-`git push origin v0.35.1`
6. Create a pull request back to master with the CHANGELOG & version changes from the latest release.
- Remove all `R:minor` labels from the pull requests that were included in the release.
