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
* clarify p2p backwards compatibility
* reorder p2p queue list
* add demo for p2p selection
* 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.
I realized after my last commit that my change made a following line of code a bit redundant.
(alternatively my last change was redunadnt to the existing code.)
I took this oppertunity to make some minor cleanups and logging changes to the node changes which I hope will make tests a bit more clear.

We INFO log every `ABCIQuery`. This can output a tremendous amount of noise in the logs, can cause cosmovisor to completely crash and slows down the node due to I/O. This log is completely unnecessary.
Let's get this backported into v0.43 and get that into v0.43 and v0.42 releases of the SDK

As written, the encoding step unnecessarily made and moved multiple copies of
the encoded representation. Reduce this to a single allocation and encode the
data in-place so that a shift is no longer required.
Also: Add a test to ensure letter digits are capitalized, which was previously not
verified but was expected downstream.
No functional changes.
Adds a simple property test to the `clist` package. This test uses the [rapid](https://github.com/flyingmutant/rapid) library and works by modeling the internal clist as a simple array.
Follow up from this mornings workshop with the Regen team.
This changes adds a failing test for issue #6660. It achieves this by adding a transaction, starting the `broadcastTxRoutine` in a goroutine and then adding another transaction to the mempool. The `broadcastTxRoutine` can receive the second inserted transaction before `insertTx` returns. In that case, `broadcastTxRoutine` will derefence a nil pointer when referencing the `gossipEl` and panic.
This change aims to keep versions of mockery consistent across developer laptops.
This change adds mockery to the `tools.go` file so that its version can be managed consistently in the `go.mod` file.
Additionally, this change temporarily disables adding mockery's version number to generated files. There is an outstanding issue against the mockery project related to the version string behavior when running from `go get`. I have created a pull request to fix this issue in the mockery project.
see: https://github.com/vektra/mockery/issues/397
Update those break statements inside case clauses that are intended to reach an
enclosing for loop, so that they correctly exit the loop.
The candidate files for this change were located using:
% staticcheck -checks SA4011 ./... | cut -d: -f-2
This change is intended to preserve the intended semantics of the code, but
since the code as-written did not have its intended effect, some behaviour may
change. Specifically: Some loops may have run longer than they were supposed
to, prior to this change.
In one case I was not able to clearly determine the intended outcome. That case
has been commented but otherwise left as-written.
Fixes#6780.
This pull request removes the homegrown mocks in `light/provider/mock` in favor of mockery mocks.
Adds a simple benchmark only mock to avoid the overhead of `reflection` that `mockery` incurs.
part of #5274
This adds a test for closing the `pqueue` while the `pqueue` contains data that has not yet been dequeued.
This issue was found while debugging #6705
This test will fail until @cmwaters fix for this condition is merged.
This change does two things:
1. It fixes the json fuzzer to account for receiving array results. Arrays are returned by the rpc server when the input data is an array.
2. Adds a `fuzz_test.go` file and corresponding `testdata` directory containing the failing test case.
This seems like a reasonable way to add and track previous crash issues in our fuzz test cases. The upcoming stdlib go fuzz tool does effectively this automatically.
This change adds additional coverage to the `mConnConnection.TrySendMessage` code path. Adds test to ensure it returns `io.EOF` when closed.
Addresses: #6570
This changes adds an `MempoolError` field to the `ResponseCheckTx`. This will allow clients to understand that their transaction was rejected from the mempool despite passing the ABCI check.
This change also updates the code to make use of early returns to prevent highly nested code blocks. Namely, it returns when the type assertion fails at the beginning of the method, instead of wrapping the entire method in a large if statement. This has a somewhat large effect on the diff as rendered by github.
addresses: #3546
The Makefile at the root of the repo [includes](cd19ef244e/Makefile (L61)) the Makefile under the `test` package. This fix removes the target defined in the root Makefile in favor of the included one.
Having looked at our network address parsing and connection code, it
really looks like we're not doing anything on top of what the standard
library is doing (both in terms using `net.ParseIP` and also
`net.Dial`,) and I don't think we need to run the tests 2x the number
of times just to run through different areas of the standard
library. I think most of our users are going to be using IPv4, and
would be down to fully remove this dimension as well, if we find it's
making noise, but for now I think it's fine.
closes#2498
solves part of #3365
Note: difficult to test the event emit in SwitchToFastSync part, might need to change `stateSyncReactor` to an interface in the `nodeImpl` struct
There are many `//go:generate mockery` lines in the source code.
This change adds a make target to invoke these mock generations.
This change also invokes the mock invocations and adds the resulting mocks to the repo.
Related to #5274
This tweaks sleeps around pertubations, based on a theory that our
tests with "kill" pertubations restart the nodes fast enough the peers
haven't marked it down when it tries to reconnect. In my local test
runs, this clears out *most* of the test failures that I've seen,
except for one evidence-related test-harness problem (which should be
handled separately.)
This code change amends the dispatcher tests to read from the dispatcher's `requestCh`. This ensures that a request is waiting when the test calls `dispatcher.respond`.
addresses: #6711
I put this error log in here because I thought it might be a helpful indicator to see when a reactor sends a message to a peer that doesn't have that channel open but it turns out this is happening all the time and it's kind of annoying
This commit extends the fix in #6518, so all other goroutine which run
concurrently with processBlockchainCh can safely send data to blockchain
out channel via a bridge channel. This helps eliminating all possible
data race with sending and closing blockchainCh.Out channel at the same
time.
Fixes#6516
Closes: #6661
Note: see another error during the events indexing, guess the raw tx size exceeds the limitation?

## Description
It confused many people what they were supposed to add here. For chains with large genesis files you will only see the error after Initgenesis. Best to add a small sentence to provide better UX
At Oasis we have spend some time writing a new Ed25519/X25519/sr25519 implementation called curve25519-voi. This PR switches the import from ed25519consensus/go-schnorrkel, which should lead to performance gains on most systems.
Summary of changes:
* curve25519-voi is now used for Ed25519 operations, following the existing ZIP-215 semantics.
* curve25519-voi's public key cache is enabled (hardcoded size of 4096 entries, should be tuned, see the code comment) to accelerate repeated Ed25519 verification with the same public key(s).
* (BREAKING) curve25519-voi is now used for sr25519 operations. This is a breaking change as the current sr25519 support does something decidedly non-standard when going from a MiniSecretKey to a SecretKey and or PublicKey (The expansion routine is called twice). While I believe the new behavior (that expands once and only once) to be more "correct", this changes the semantics as implemented.
* curve25519-voi is now used for merlin since the included STROBE implementation produces much less garbage on the heap.
Side issues fixed:
* The version of go-schnorrkel that is currently imported by tendermint has a badly broken batch verification implementation. Upstream has fixed the issue after I reported it, so the version should be bumped in the interim.
Open design questions/issues:
* As noted, the public key cache size should be tuned. It is currently backed by a trivial thread-safe LRU cache, which is not scan-resistant, but replacing it with something better is a matter of implementing an interface.
* As far as I can tell, the only reason why serial verification on batch failure is necessary is to provide more detailed error messages (that are only used in some unit tests). If you trust the batch verification to be consistent with serial verification then the fallback can be eliminated entirely (the BatchVerifier provided by the new library supports an option that omits the fallback if this is chosen as the way forward).
* curve25519-voi's sr25519 support could use more optimization and more eyes on the code. The algorithm unfortunately is woefully under-specified, and the implementation was done primarily because I got really sad when I actually looked at go-schnorrkel, and we do not use the algorithm at this time.
Closes#6551
Simple PR to add the total gas used in the block by adding the gas used in all the transactions.
This adds a `TotalGasUsed` field to `coretypes.ResultBlockResults`.
Its my first PR to the repo so let me know if there is anything I am missing!
@fedekunze In case you want to take a look
This PR make some tweaks to backfill after running e2e tests:
- Separates sync and backfill as two distinct processes that the node calls. The reason is because if sync fails then the node should fail but if backfill fails it is still possible to proceed.
- Removes peers who don't have the block at a height from the local peer list. As the process goes backwards if a node doesn't have a block at a height they're likely pruning blocks and thus they won't have any prior ones either.
- Sleep when we've run out of peers, then try again.
There is a possible data race/panic between processBlockchainCh and
processPeerUpdates, since when we send to blockchainCh.Out in one
goroutine and close the channel in the other. The race is seen in some
Github Action runs.
This commit fix the race, by adding a peerUpdatesCh as a bridge between
processPeerUpdates and processBlockchainCh, so the former will send to
this channel, the later will listen and forward the message to
blockchainCh.Out channel.

## Description
Trying to debug a possible hashing issue, writing test vectors on 0.34 and then porting them to master to double-check it's not a hashing issue.
Per tendermint spec, each Channel has a globally unique byte id, which
is mapped to uint8 in Go. However, the proto PacketMsg.ChannelID field
is declared as int32, and when receive the packet, we cast it to a byte
without checking for possible overflow. That leads to a malform packet
with invalid channel id is sent successfully.
To fix it, we just add a check for possible overflow, and return invalid
channel id error.

## Description
Internalize some libs. This reduces the amount ot public API tendermint is supporting. The moved libraries are mainly ones that are used within Tendermint-core.
To make sure finalizers run, we use channel for synchronization, and a
separate goroutine for trigger runtime.GC every 1 second. In practice,
just two consecutive runtime.GC calls can make all finalizers will run,
but using a separate goroutine make the code more robust and not depend
on garbage collector internal implementation.
Fixes#6452
This change fixes a potential exploitable vulnerability
that can cause the WAL to be consistently truncated by falsely
supplying the WAL path which would be any arbitrary dirrectory.
Fixes#6427
Somehow my previous attempt to fix this test was somewhat
non-deterministic. I think I misjudged how the "median" would impact
the test.
I ran the test in question 10 times without seeing a failure (which
would show up 10-30% of the time previously,) so I'm pretty sure this
is fixed.

I believe that this, in my testing seems to help the e2e state-sync
tests complete more reliably, by fixing some potential, range-related
slice building, as well as the way the test app hashes snapshots.
Additionally, and I'm not sure if we want to do this, but I added this
hook to the reactor that re-sends the request for snapshots during the
retry. This helps in tests prevent systems from getting stuck, but I
think in reality, it might create more traffic, and operators would
just restart a state-syncing node to get a similar effect.
Per conversations earlier today, we'll consider all proposed implementation changes part of the ADR process rather than the RFC process (which will remain, for now, on the spec; this may get incorporated instead into the burgeoning "CIPS" process).
This change renames RFC 1 to ADR 66, leaving space for the not-yet-merged ADR 65.

## Description
- Add `context.Context` to Privval interface
This pr does not introduce context into our custom privval connection protocol because this will be removed in the next release. When this pr is released.
## Description
Since events are not hashed into the header they can be non deterministic. Changing an event is not consensus breaking. Will update docs in the spec
* test/fuzz: fix rpc, secret_connection and pex tests
- ignore empty data in rpc
- provide correct IP in pex
- spawn a goroutine for Write and do multiple Read(s)
* test/fuzz: fix init in pex test
* test/fuzz: assign NewServeMux to global var
* test/fuzz: only try to Unmarshal if blob is not empty
* run fuzz tests for PRs which modify fuzz tests themselves
* test/fuzz: move MakeSwitch into init
Introduces heuristics that track the amount of no responses or unavailable blocks a provider has for more robust provider handling by the light client. Use concurrent calls to all witnesses when a new primary is needed.
also
- replace `MaxReconnectAttempts`, `ReadWait`, `WriteWait` and `PingPeriod` options with `WSOptions` in `WSClient` (rpc/jsonrpc/client/ws_client.go).
- set default write wait to 10s for `WSClient`(rpc/jsonrpc/client/ws_client.go)
- unexpose `WSEvents`(rpc/client/http.go)
Closes#6162
## Description
Fixes marshaling error in sdk
closes https://github.com/cosmos/cosmos-sdk/issues/8578
the output stays the same, we are avoiding the passing of the callback because sdk uses typed logging.
```
// unbuffered
out, err := httpClient.Subscribe(ctx, "event.type=NewTx and account.name=Jack", 0)
// buffered
out, err := httpClient.Subscribe(ctx, "event.type=NewTx AND account.name=Jack", 20)
```
Before: when the `out` channel is buffered and becomes full, we drop an event (+ log the error)
After: when the `out` channel is buffered and becomes full, we block
**Before it was not apparent to the app when an event was dropped (looking at the logs is manual task). After this PR, if the user does not read from `out` on 1 subscription, all other subscriptions will be stuck too.**
Closes#6161
I'm also going to add the retros for all previous security incidents to this directory - I'd like to have them somewhere more central than the Cosmos Forum, where they currently live.
Missed setting the buffer size on the subscription. Note, this doesn't really "fix" this test (a la ref: https://github.com/tendermint/tendermint/pull/5710).
However, I spent a good chunk of time looking at this test with many logs and I'm pretty sure this is mainly due to the fact that none of the nodes get the conflicting vote in time.
closes: #6127
Fixes the race condition between a callback being set and called during ReCheckTx. Note, I do not see equivalent logic in the gRPC client (anymore) as #5439 suggests, so only the socket client was updated.
closes: #5439

I got tired of seeing the literal phrase "Closes #XXX" left in PR bodies.
Also, this template isn't usually viewed as rendered markdown, so I've removed the markdown formatting and the "Description" heading (which usually gets deleted anyways).
This cleans up the `Router` code and adds a bunch of tests. These sorts of systems are a real pain to test, since they have a bunch of asynchronous goroutines living their own lives, so the test coverage is decent but not fantastic. Luckily we've been able to move all of the complex peer management and transport logic outside of the router, as synchronous components that are much easier to test, so the core router logic is fairly small and simple.
This also provides some initial test tooling in `p2p/p2ptest` that automatically sets up in-memory networks and channels for use in integration tests. It also includes channel-oriented test asserters in `p2p/p2ptest/require.go`, but these have primarily been written for router testing and should probably be adapted or extended for reactor testing.
E2E tests often fail because validators miss signing or proposing blocks. Often this is because e.g. there's a lot of disruption in the network or it takes a long time to start up all the nodes.
This changes the test criteria to only check for 3 signed/proposed blocks, rather than a fraction of the expected blocks. This should be enough to catch most issues, apart from performance problems causing nodes to miss signing/proposing, but we may want separate tests for those sorts of things.
This renames `PeerAddress` to `NodeAddress`, moves it and `NodeID` into a separate file `address.go`, adds tests for them, and fixes a bunch of bugs and inconsistencies.
This revises the new P2P `Transport` interface and does some preliminary code cleanups and simplifications.
The major change here is to add `Connection.Handshake()` for performing node handshakes (once the stream transport API is implemented, this can be done entirely independent of the transport). This moves most of the handshaking logic into the `Router`, such as prevention of head-of-line blocking, validation of peer's `NodeInfo`, controlling timeouts, and so on. This significantly simplifies transports, completely removes the need for internal goroutines, and shares common logic across all transports. This also allows varying the handshake `NodeInfo` across peers, e.g. to vary `ListenAddr`. Similarly, connection filtering is also moved into the switch/router so that it can be shared between transports.
Fixes#5981, which was caused by changes in Router behavior after the introduction of the peer manager, leading to a race condition that could halt the test.
This is a temporary measure, I'll start tightening up the new P2P core tomorrow and write "real" tests with better test infrastructure.
This patches over a test data race where the logger would try to read struct internals via `reflect` while these were concurrently modified (specifically `MemoryTransport.closeOnce`).
Executed a local network using simapp and looked for logs that seemed superfluous. This isn't by any means an exhaustive grooming, but should drastically help legibility of logs.
ref: #5912
This test occasionally fails because the peer is already stopped. It is unclear to me exactly what this test is supposed to do, since calling `FlushStop()` will stop the peer, but the test asserts that the peer shouldn't have been stopped by `FlushStop()` since calling `Stop()` afterwards will error in that case.
The current PEX reactor will be removed in the new P2P stack anyway.
Fixes#5998. Sometimes the connection returns "use of closed network connection" instead, so for now we just accept any error. The switch is not long for this world anyway.
This test relied on connecting to the external site `foo-bar.net`, and (predictably) the site went down and broke all of our CI runs. This changes it to use local HTTP servers instead.
This changes the new prototype PEX reactor to resolve peer address URLs into IP/port PEX addresses itself. Branched off of #5974.
I've spent some time thinking about address handling in the P2P stack. We currently use `PeerAddress` URLs everywhere, except for two places: when dialing a peer, and when exchanging addresses via PEX. We had two options:
1. Resolve addresses to endpoints inside `PeerManager`. This would introduce a lot of added complexity: we would have to track connection statistics per endpoint, have goroutines that asynchronously resolve and refresh these endpoints, deal with resolve scheduling before dialing (which is trickier than it sounds since it involves multiple goroutines in the peer manager and router and messes with peer rating order), handle IP address visibility issues, and so on.
2. Resolve addresses to endpoints (IP/port) only where they're used: when dialing, and in PEX. Everywhere else we use URLs.
I went with 2, because this significantly simplifies the handling of hostname resolution, and because I really think the PEX reactor should migrate to exchanging URLs instead of IP/port numbers anyway -- this allows operators to use DNS names for validators (and can easily migrate them to new IPs and/or load balance requests), and also allows different protocols (e.g. QUIC and `MemoryTransport`). Happy to discuss this.
Fixes#5899 by renaming a bunch of P2P Protobuf entities (while maintaining wire compatibility):
* `Message` to `PexMessage` (as it's only used for PEX messages).
* `PexAddrs` to `PexResponse`.
* `PexResponse.Addrs` to `PexResponse.Addresses`.
* `NetAddress` to `PexAddress` (as it's only used by PEX).
## Description
Fixes the data race in usage of `WaitGroup`. Specifically, the case where we invoke `Wait` _before_ the first delta `Add` call when the current waitgroup counter is zero. See https://golang.org/pkg/sync/#WaitGroup.Add.
Still not sure how this manifests itself in a test since the reactor has to be stopped virtually immediately after being started (I think?).
Regardless, this is the appropriate fix.
closes: #5968
Adds a naïve `PeerManager.Advertise()` method that the new PEX reactor can use to fetch addresses to advertise, as well as some other `FIXME`s on address advertisement.
Follow-up from #5947, branched off of #5954.
This simplifies the upgrade logic by adding explicit eviction requests, which can also be useful for other use-cases (e.g. if we need to ban a peer that's misbehaving). Changes:
* Add `evict` map which queues up peers to explicitly evict.
* `upgrading` now only tracks peers that we're upgrading via dialing (`DialNext` → `Dialed`/`DialFailed`).
* `Dialed` will unmark `upgrading`, and queue `evict` if still beyond capacity.
* `Accepted` will pick a random lower-scored peer to upgrade to, if appropriate, and doesn't care about `upgrading` (the dial will fail later, since it's already connected).
* `EvictNext` will return a peer scheduled in `evict` if any, otherwise if beyond capacity just evict the lowest-scored peer.
This limits all of the `upgrading` logic to `DialNext`, `Dialed`, and `DialFailed`, making it much simplier, and it should generally do the right thing in all cases I can think of.
This improves the `peerStore` prototype by e.g.:
* Using a database with Protobuf for persistence, but also keeping full peer set in memory for performance.
* Simplifying the API, by taking/returning struct copies for safety, and removing errors for in-memory operations.
* Caching the ranked peer set, as a temporary solution until a better data structure is implemented.
* Adding `PeerManagerOptions.MaxPeers` and pruning the peer store (based on rank) when it's full.
* Rewriting `PeerAddress` to be independent of `url.URL`, normalizing it and tightening semantics.
## Description
Update the faux router to either drop channel errors or handle them based on an argument. This prevents deadlocks in tests where we try to send an error on the mempool channel but there is no reader.
Closes: #5956
See #5936 and #5938 for background.
The plan was initially to have `DialNext()` and `EvictNext()` return a channel. However, implementing this became unnecessarily complicated and error-prone. As an example, the channel would be both consumed and populated (via method calls) by the same driving method (e.g. `Router.dialPeers()`) which could easily cause deadlocks where a method call blocked while sending on the channel that the caller itself was responsible for consuming (but couldn't since it was busy making the method call). It would also require a set of goroutines in the peer manager that would interact with the goroutines in the router in non-obvious ways, and fully populating the channel on startup could cause deadlocks with other startup tasks. Several issues like these made the solution hard to reason about.
I therefore simply made `DialNext()` and `EvictNext()` block until the next peer was available, using internal triggers to wake these methods up in a non-blocking fashion when any relevant state changes occurred. This proved much simpler to reason about, since there are no goroutines in the peer manager (except for trivial retry timers), nor any blocking channel sends, and it instead relies entirely on the existing goroutine structure of the router for concurrency. This also happens to be the same pattern used by the `Transport.Accept()` API, following Go stdlib conventions, so all router goroutines end up using a consistent pattern as well.

Fixes#5941.
Not entirely sure that this will fix the problem (couldn't reproduce), but in any case this is an artifact of a hack in the P2P transport refactor to make it work with the legacy P2P stack, and will be removed when the refactor is done anyway.
The `proto-gen-docker` target didn't pull an updated Docker image, and would use a local image if present which could be outdated and produce wrong results.
This improves the prototype peer manager by:
* Exporting `PeerManager`, making it accessible by e.g. reactors.
* Replacing `Router.SubscribePeerUpdates()` with `PeerManager.Subscribe()`.
* Tracking address/peer connection statistics, and retrying dial failures with exponential backoff.
* Prioritizing peers, with persistent peers configuration.
* Limiting simultaneous connections.
* Evicting peers and upgrading to higher-priority peers.
* Tracking peer heights, as a workaround for legacy shared peer state APIs.
This is getting to a point where we need to determine precise semantics and implement tests, so we should figure out whether it's a reasonable abstraction that we want to use. The main questions are around the API model (i.e. synchronous method calls with the router polling the manager, vs. an event-driven model using channels, vs. the peer manager calling methods on the router to connect/disconnect peers), and who should have the responsibility of managing actual connections (currently the router, while the manager only tracks peer state).
Conflicting votes are now sent to the evidence pool to form duplicate vote evidence only once
the height of the evidence is finished and the time of the block finalised.
This adds a prototype peer lifecycle manager, `peerManager`, which stores peer data in an internal `peerStore`. The overall idea here is to have methods for peer lifecycle events which exchange a very narrow subset of peer data, and to keep all of the peer metadata (i.e. the `peerInfo` struct) internal, to decouple this from the router and simplify concurrency control. See `peerManager` GoDoc for more information.
The router is still responsible for actually dialing and accepting peer connections, and routing messages across them, but the peer manager is responsible for determining which peers to dial next, preventing multiple connections being established for the same peer (e.g. both inbound and outbound), and making sure we don't dial the same peer several times in parallel. Later it will also track retries and exponential backoff, as well as peer and address quality. It also assumes responsibility for peer updates subscriptions.
It's a bit unclear to me whether we want the peer manager to take on the responsibility of actually dialing and accepting connections as well, or if it should only be tracking peer state for the router while the router is responsible for all transport concerns. Let's revisit this later.

Early but functional prototype of the new `p2p.Router`, see its GoDoc comment for details on how it works. Expect much of this logic to change and improve as we evolve the new P2P stack.
There is a simple test that sets up an in-memory network of four routers with reactors and passes messages between them, but otherwise no exhaustive tests since this is very much a work-in-progress.
E2E tests often fail due to fast sync stalls causing the validator to miss signing blocks. This increases the tolerance for missed signatures to 2/3 to allow validators to spend more time starting up.
#5852 fixed an issue with error propagation in `os.EnsureDir()`. However, this function is basically identical to `os.MkdirAll()`, and can be replaced entirely with a call to it. We keep the function for backwards compatibility.
blockchain/vX reactor priority was decreased because during the normal operation
(i.e. when the node is not fast syncing) blockchain priority can't be
the same as consensus reactor priority. Otherwise, it's theoretically possible to
slow down consensus by constantly requesting blocks from the node.
NOTE: ideally blockchain/vX reactor priority would be dynamic. e.g. when
the node is fast syncing, the priority is 10 (max), but when it's done
fast syncing - the priority gets decreased to 5 (only to serve blocks
for other nodes). But it's not possible now, therefore I decided to
focus on the normal operation (priority = 5).
evidence and consensus critical messages are more important than
the mempool ones, hence priorities are bumped by 1 (from 5 to 6).
statesync reactor priority was changed from 1 to 5 to be the same as
blockchain/vX priority.

@p4u from vocdoni.io reported that the mempool might behave incorrectly under a
high load. The consequences can range from pauses between blocks to the peers
disconnecting from this node.
My current theory is that the flowrate lib we're using to control flow
(multiplex over a single TCP connection) was not designed w/ large blobs
(1MB batch of txs) in mind.
I've tried decreasing the Mempool reactor priority, but that did not
have any visible effect. What actually worked is adding a time.Sleep
into mempool.Reactor#broadcastTxRoutine after an each successful send ==
manual control flow of sort.
As a temporary remedy (until the mempool package
is refactored), the max-batch-bytes was disabled. Transactions will be sent
one by one without batching
Closes#5796
When set to true, an invalid transaction will be kept in the cache (this may help some applications to protect against spam).
NOTE: this is a temporary config option. The more correct solution would be to add a TTL to each transaction (i.e. CheckTx may return a TTL in ResponseCheckTx).

time_iota_ms is intended to ensure that an honest validator always generates timestamps
with time increasing monotonically. For this purpose, it always suffices to have this parameter
set to `1ms`. Allowing users to choose different numbers increases bug surface area.
Thus the code now ignores the user provided time_iota_ms parameter (marking it as unused),
and uses 1ms internally.
The MTU (Maximum Transmission Unit) for Ethernet is 1500 bytes.
The IP header and the TCP header take up 20 bytes each at least (unless
optional header fields are used) and thus the max for (non-Jumbo frame)
Ethernet is 1500 - 20 -20 = 1460

While debugging the mempool issue (#5796), I've noticed we're spending
quite a bit of time encoding blobs of data, which never get printed! The
reason is filtering occurs on the level below, so Go runtime rightfully
evaluates function arguments.
I think it's okay to not format raw bytes.
The `NodeInfo` interface does not appear to serve any purpose at all, so I removed it and renamed the `DefaultNodeInfo` struct to `NodeInfo` (including the Protobuf representations). Let me know if this is actually needed for anything.
Only the Protobuf rename is listed in the changelog, since we do not officially support API stability of the `p2p` package (according to `README.md`). The on-wire protocol remains compatible.
This implements a new `Transport` interface and related types for the P2P refactor in #5670. Previously, `conn.MConnection` was very tightly coupled to the `Peer` implementation -- in order to allow alternative non-multiplexed transports (e.g. QUIC), MConnection has now been moved below the `Transport` interface, as `MConnTransport`, and decoupled from the peer. Since the `p2p` package is not covered by our Go API stability, this is not considered a breaking change, and not listed in the changelog.
The initial approach was to implement the new interface in its final form (which also involved possible protocol changes, see https://github.com/tendermint/spec/pull/227). However, it turned out that this would require a large amount of changes to existing P2P code because of the previous tight coupling between `Peer` and `MConnection` and the reliance on subtleties in the MConnection behavior. Instead, I have broadened the `Transport` interface to expose much of the existing MConnection interface, preserved much of the existing MConnection logic and behavior in the transport implementation, and tried to make as few changes to the rest of the P2P stack as possible. We will instead reduce this interface gradually as we refactor other parts of the P2P stack.
The low-level transport code and protocol (e.g. MConnection, SecretConnection and so on) has not been significantly changed, and refactoring this is not a priority until we come up with a plan for QUIC adoption, as we may end up discarding the MConnection code entirely.
There are no tests of the new `MConnTransport`, as this code is likely to evolve as we proceed with the P2P refactor, but tests should be added before a final release. The E2E tests are sufficient for basic validation in the meanwhile.
Closes#5766
* memoize the scSchedulerFail error to avoid printing it every scheduleFreq
* blockchain/v2: modify switchIO funcs to accept peer instead of peerID
`Makefile` used `git branch --show-current` for branch detection. This option was introduced in Git 2.22. However, the current Debian release (Buster), which is used by the `golang:1.15` Docker image, uses Git 2.20. This gives spurious errors e.g. when running the E2E tests:
```
error: unknown option `show-current'
```
This PR changes the branch detection to be compatible with Git 2.20. The behavior appears to be the same as `git branch --show-current`, both when on a branch, on a tag, and on a detached HEAD.

also, include node ID in the output (#5769) and modify NodeKey to use

After a reactor has failed to parse an incoming message, it shouldn't output the "bad" data into the logs, as that data is unfiltered and could have anything in it. (We also don't think this information is helpful to have in the logs anyways.)
Replace testing.T.Cleanup() with deferred function
calls in test helpers as those cleanup functions
need to be called once the helper returns and not
when the entire test ends.
This reverts a few of the changes introduced in #5723.
Thanks: @erikgrinaker for pointing this out.
Ref: #5732
*testing.T.TempDir() causes test cases to fail when
it is unable to remove the temporary directory once
the test case execution terminates. This seems to
happen often with pex reactor test cases.
I introduced a new variable - syncEnded, which is now used to prevent
sending new events to channels (which would block otherwise) if reactor
is finished syncing
Closes#4591
## Description
I'm just doing a self audit of the light client. There's a few things I've changed
- Validate trust level in `VerifyNonAdjacent` function
- Make errNoWitnesses public (it's something people running software on top of a light client should be able to parse)
- Remove `ChainID` check of witnesses on start up. We do this already when we compare the first header with witnesses
- Remove `ChainID()` from provider interface
Closes: #4538
`abci.Client`:
- Sync and Async methods now accept a context for cancellation
* grpc client uses context to cancel both Sync and Async requests
* local client ignores context parameter
* socket client uses context to cancel Sync requests and to drop Async requests before sending them if context was cancelled prior to that
- Async methods return an error
* socket client returns an error immediately if queue is full for Async requests
* local client always returns nil error
* grpc client returns an error if context was cancelled before we got response or the receiving queue had a space for response (do not confuse with the sending queue from the socket client)
- specify clients semantics in [doc.go](https://raw.githubusercontent.com/tendermint/tendermint/27112fffa62276bc016d56741f686f0f77931748/abci/client/doc.go)
`mempool.TxInfo`
- add optional `Context` to `TxInfo`, which can be used to cancel `CheckTx` request

helper.
Mark auxiliary functions as test helpers.
This fixes spurious `TestByzantinePrevoteEquivocation` failures by extending the block range and time spent waiting for evidence. I've seen many runs where the evidence isn't committed until e.g. height 27. Haven't looked into _why_ this happens, but as long as the evidence is committed eventually and the test doesn't spuriously fail I'm (mostly) happy. WDYT @cmwaters?
## Description
- separate docs related to running nodes into the nodes dir.
- keep old files but dont display them
- bring over debugging like a pro blog
Closes: #XXX
Closes#5444
Now we record the fact that a peer does not have a requested block and later use this information to make a new request for the same block from another peer.
## Description
Hardcode ed25519 to dialTCPFn in e2e tests.
I will backport `DefaultRequestHandler` fixes
This will be replaced when grpc is implemented.
## Description
- remove installation of protoc
- use buf protoc to generate proto stubs
prior to approving could someone test locally. I restarted my docker instance and its been stuck for 20+ minutes

This is the first iteration of model-based testing in Go Tendermint. The test runner is using the static JSON fixtures located under the ./json directory. In the future, the Rust tensgen binary will be used to generate those (given the static intermediate scenarios and the test seed, which will be published along with each testgen release).
Closes: #5322
Removes `p2p.FuzzedConnection`, since it does not appear to be in use. While these sorts of test wrappers may be useful, they should be injected directly instead of bleeding through into the main application configuration. We'll implement something similar if and when necessary, for the new P2P abstractions in #2067.
* Don't use state sync for nodes starting at initial height.
* Also remove stopped containers when cleaning up.
* Start nodes in order of startAt, mode, name to avoid full nodes starting before their seeds.
* Tweak network waiting to avoid halts caused by validator changes and perturbations.
* Disable most tests for seed nodes, which aren't always able to join consensus.
* Disable `blockchain/v2` due to known bugs.
In #5488 the E2E testnet generator changed to setting explicit `StartAt` heights for initial nodes. This broke the runner, which expected all initial nodes to have `StartAt: 0`, as well as validator set scheduling in the generator. Testnet loading now normalizes initial nodes to have `StartAt: 0`.
This also tweaks waiting for misbehavior heights to only use an additional wait if there actually is any misbehavior in the testnet, and to output information when waiting.
Fixes#5540, fixes#2965. This is a hack that patches over the problem, but really the whole async handling in gRPC should be redesigned, as should ReqRes callback dispatch.
Before: scheduler receives psBlockProcessed event, but does not mark block as processed because peer timed out (or was removed for other reasons) and all associated blocks were rescheduled.
After: scheduler receives psBlockProcessed event and marks block as processed in any case (even if peer who provided this block errors).
Closes#5387
When a peer is stopped due to some network issue, the Reactor calls scheduler#handleRemovePeer, which removes the peer from the scheduler. BUT the peer stays in the processor, which sometimes could lead to "duplicate block enqueued by processor" panic WHEN the same block is requested by the scheduler again from a different peer. The solution is to return scPeerError, which will be propagated to the processor. The processor will clean up the blocks associated with the peer in purgePeer.
Closes#5513, #5517
Fixes#5439. This is really a workaround for #5519 (unless we require async implementations to return ordered responses, but that kind of defeats the purpose of having an async API).

Closes#5291. Adds a randomized testnet generator. Nightly CI job will be submitted separately. A few of the testnets can be a bit flaky, even after disabling known-faulty behavior and making minor tweaks, and the larger networks may be too resource-intensive to run in CI - this will be optimized separately.
This was a missing test case from the old P2P tests removed in #5453, which makes sure that all nodes are able to peer with each other regardless of how they discover peers.
Fixes#2795, since the default CI testnet uses a combination of (partially meshed) persistent peers and PEX-based seed nodes.
## Description
In blocks_results we use the proto definition of abciResponses: 2672b91ab0/rpc/core/blocks.go (L152-L155), this leads to the use of the proto definition of the pubkey which is an interface in go (oneof). The interface must be registered with the JSON encoder to have it work correctly.
A clearer divide between proto types and native types is needed.
Closes: #XXX
Partial fix for #5291.
This adds a basic set of test cases for core network invariants. Although small, it is sufficient to replace and extend the current set of P2P tests. Further test cases can be added later.
## Description
Add simple `NoBlockResponse` handling to blockchain reactor v1. I tested before and after with erik's e2e testing and was not able to reproduce the inability to sync after the changes were applied

and `TxInfo`. (@alexanderbez)
- [crypto/sr25519] \#6526 Do not re-execute the Ed25519-style key derivation step when doing signing and verification. The derivation is now done once and only once. This breaks `sr25519.GenPrivKeyFromSecret` output compatibility. (@Yawning)

### FEATURES
- [\#6982](https://github.com/tendermint/tendermint/pull/6982) The tendermint binary now has built-in suppport for running the end-to-end test application (with state sync support) (@cmwaters).
- [cli] [#7033](https://github.com/tendermint/tendermint/pull/7033) Add a `rollback` command to rollback to the previous tendermint state. This may be useful in the event of non-determinstic app hash or when reverting an upgrade.@cmwaters
- [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 type
- [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)
- [blocksync/event] \#6619 Emit blocksync status event when switching consensus/blocksync (@JayT106)
- [statesync/event] \#6700 Emit statesync status start/end event (@JayT106)
- [inspect] \#6785 Add a new `inspect` command for introspecting the state and block store of a crashed tendermint node. (@williambanfield)
### IMPROVEMENTS
- [\#7103](https://github.com/tendermint/tendermint/pull/7104) Remove IAVL dependency (backport of #6550) (@cmwaters)
- [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)
- [blocksync/v2] \#5774 Send status request when new peer joins (@melekes)
- [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 and \#5792 Remove the `time_iota_ms` consensus parameter. Merge `tmproto.ConsensusParams` and `abci.ConsensusParams`. (@marbar3778, @valardragon)
- [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.

### Release Procedure
### Release procedure
#### Major Release
#### 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.Run integration tests (see `test_integrations` in Makefile)
3. Prepare release in a pull request against `master` (to be squash merged):
- Copy `CHANGELOG_PENDING.md` to top of `CHANGELOG.md`; if this release
had release candidates, squash all the RC updates into one
- 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 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
- Make sure all significant breaking changes are covered in `UPGRADING.md`
- Add any release notes you would like to be added to the body of the release to `release_notes.md`.
4. Push a tag with prepared release details (this will trigger the release `vX.X.0`)
-`git tag -a vX.X.x -m 'Release vX.X.x'`
-`git push origin vX.X.x`
5. Update the changelog.md file on master with the releases changelog.
6. Delete any RC branches and tags for this release (if applicable)
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.)
#### Minor Release
Minor releases are done differently from major releases: They are built off of long-lived release candidate branches, rather than from master.
1. Checkout the long-lived release candidate branch: `git checkout rcX/vX.X.X`
2. Run integration tests: `make test_integrations`
3. 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 P2P and block protocol versions in `version.go`, if necessary
- bump ABCI protocol version in `version.go`, if necessary
- make sure all significant breaking changes are covered in `UPGRADING.md`
- Add any release notes you would like to be added to the body of the release to `release_notes.md`.
4. Create a release branch `release/vX.X.x` off the release candidate branch:
-`git checkout -b release/vX.X.x`
-`git push -u origin release/vX.X.x`
- Note that all branches prefixed with `release` are protected once pushed. You will need admin help to make any changes to the branch.
5. Once the release branch has been approved, make sure to pull it locally, then push a tag.
-`git tag -a vX.X.x -m 'Release vX.X.x'`
-`git push origin vX.X.x`
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.
- Do not merge the release branch into master.
7. Delete the former long lived release candidate branch once the release has been made.
8. Create a new release candidate branch to be used for the next release.
#### Backport Release
1. start from the existing release branch you want to backport changes to (e.g. v0.30)
Branch to a release/vX.X.X branch locally (e.g. release/v0.30.7)
2. Cherry pick the commit(s) that contain the changes you want to backport (usually these commits are from squash-merged PRs which were already reviewed)
3. Follow steps 2 and 3 from [Major Release](#major-release)
4. Push changes to release/vX.X.X branch
5. Open a PR against the existing vX.X branch
#### Release Candidates
#### 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 RC branches. RC branches typically have names formatted
like `RCX/vX.X.X` (or, concretely, `RC0/v0.34.0`), while the tags themselves follow
the "standard" release naming conventions, with `-rcX` at the end (`vX.X.X-rcX`).
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.)
1. Start from the RC branch (e.g. `RC0/v0.34.0`).
2. Create the new tag, specifying a name and a tag "message":
`git tag -a v0.34.0-rc0 -m "Release Candidate v0.34.0-rc0`
3.Push the tag back up to origin:
`git push origin v0.34.0-rc4`
Now the tag should be available on the repo's releases page.
4. Create a new release candidate branch for any possible updates to the RC:
- 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
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.)
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.
- Do not merge the backport branch into master.

## Disclosure Process
## Disclosure Process
Tendermint Core uses the following disclosure process:
1. Once a security report is received, the Tendermint Core team works to verify the issue and confirm its severity level using CVSS.
2. The Tendermint Core team collaborates with the Gaia team to determine the vulnerability’s potential impact on the Cosmos Hub.
3. Patches are prepared for eligible releases of Tendermint in private repositories. See “Supported Releases” below for more information on which releases are considered eligible.
4. If it is determined that a CVE-ID is required, we request a CVE through a CVE Numbering Authority.

4. If it is determined that a CVE-ID is required, we request a CVE through a CVE Numbering Authority.
5. We notify the community that a security release is coming, to give users time to prepare their systems for the update. Notifications can include forum posts, tweets, and emails to partners and validators, including emails sent to the [Tendermint Security Mailing List](https://berlin.us4.list-manage.com/subscribe?u=431b35421ff7edcc77df5df10&id=3fe93307bc).
6. 24 hours following this notification, the fixes are applied publicly and new releases are issued.
7. Cosmos SDK and Gaia update their Tendermint Core dependencies to use these releases, and then themselves issue new releases.
8. Once releases are available for Tendermint Core, Cosmos SDK and Gaia, we notify the community, again, through the same channels as above. We also publish a Security Advisory on Github and publish the CVE, as long as neither the Security Advisory nor the CVE include any information on how to exploit these vulnerabilities beyond what information is already available in the patch itself.
9. Once the community is notified, we will pay out any relevant bug bounties to submitters.
10. One week after the releases go out, we will publish a post with further details on the vulnerability as well as our response to it.

This process can take some time. Every effort will be made to handle the bug in as timely a manner as possible, however it's important that we follow the process described above to ensure that disclosures are handled consistently and to keep Tendermint Core and its downstream dependent projects--including but not limited to Gaia and the Cosmos Hub--as secure as possible.

## v0.35
### ABCI Changes
* Added `AbciVersion` to `RequestInfo`. Applications should check that the ABCI version they expect is being used in order to avoid unimplemented changes errors.
* The method `SetOption` has been removed from the ABCI.Client interface. This feature was used in the early ABCI implementation's.
* Messages are written to a byte stream using uin64 length delimiters instead of int64.
* When mempool `v1` is enabled, transactions broadcasted via `sync` mode may return a successful
response with a transaction hash indicating that the transaction was successfully inserted into
the mempool. While this is true for `v0`, the `v1` mempool reactor may at a later point in time
evict or even drop this transaction after a hash has been returned. Thus, the user or client must
query for that transaction to check if it is still in the mempool.
### Config Changes
* The configuration file field `[fastsync]` has been renamed to `[blocksync]`.
* The top level configuration file field `fast-sync` has moved under the new `[blocksync]`
field as `blocksync.enable`.
*`blocksync.version = "v1"` and `blocksync.version = "v2"` (previously `fastsync`)
are no longer supported. Please use `v0` instead. During the v0.35 release cycle, `v0` was
determined to suit the existing needs and the cost of maintaining the `v1` and `v2` modules
was determined to be greater than necessary.
* All config parameters are now hyphen-case (also known as kebab-case) instead of snake_case. Before restarting the node make sure
you have updated all the variables in your `config.toml` file.
* Added `--mode` flag and `mode` config variable on `config.toml` for setting Mode of the Node: `full` | `validator` | `seed` (default: `full`)
* `Client` object, which represents the complete light client
* The new light clients stores headers & validator sets as `LightBlock`s
* The RPC client can be found in the `/rpc` directory.
* The HTTP(S) proxy is located in the `/proxy` directory.
