Closes#7073
As part of the 0.36 cycle we've discussed and decided to remove the mutex in tendermint that protects the ABCI application. First, applications should be able to be responsible for their own concurrency control, and can make more fine-grained decisions about concurrent use than tendermint ever could. Second, I've observed in recent weeks as we've been making this change that the mutex wasn't applied particularly consistently in many cases (e.g. multiple "local" connections to the application had multiple locks, etc.) so this will give more consistent experiences across ABCI execution environments, and simplifies the tendermint ABCI handling code.
- Update documentation to deprecate the old methods.
- Add Events methods to HTTP, WS, and Local clients.
- Add Events method to the light client wrapper.
- Rename legacy events client to SubscriptionClient.
* event: Added Events after evidence validation; evidence: refactored AddEvidence
Added context and Metrics as parameter for the pool constructor
* evidence: pushed event firing into evidence pool and added metrics to represent the size of the evpool
* state: fixed parameters of evpool mock functions
* evidence: added test to confirm events are generated
* Removed obsolete EvidenceEventPublisher interface
* evidence: pool removed error on missing eventbus
When testing rollback feature in the Cosmos SDK, we found that the app hash
in Tendermint after rollback was the value after the latest block, rather than
before it.

These are only ever used with the defaults, except in our own tests. A search
of cs.github.com shows no other callers.
The use in the test was solely to bug out the go-metrics package so its
goroutines don't trigger the leak checker. Use the package's own flag for that
purpose instead. Note that calling "Stop" on the metric helps, but is not
sufficient -- the Stop does not wait for its goroutine to exit.
* rpc/coretypes: add `ApplicationInfo` to `ResultStatus`
* internal/rpc/core: return application version

This pull request merges in the changes for implementing Proposer-based timestamps into `master`. The power was primarily being done in the `wb/proposer-based-timestamps` branch, with changes being merged into that branch during development. This pull request represents an amalgamation of the changes made into that development branch. All of the changes that were placed into that branch have been cleanly rebased on top of the latest `master`. The changes compile and the tests pass insofar as our tests in general pass.
### Note To Reviewers
These changes have been extensively reviewed during development. There is not much new here. In the interest of making effective use of time, I would recommend against trying to perform a complete audit of the changes presented and instead examine for mistakes that may have occurred during the process of rebasing the changes. I gave the complete change set a first pass for any issues, but additional eyes would be very appreciated.
In sum, this change set does the following:
closes#6942
merges in #6849
There are no further uses of this package anywhere in Tendermint.
All the uses in the Cosmos SDK are for types that now work correctly with the
standard encoding/json package.
*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 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.
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.
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
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:

Thanks to Tharsis who tasked me to help them increase TPS and who
are keen on improving Tendermint and efficiency.
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.
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.
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.
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 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.
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.
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.
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.
