* rpc/client: remove the placeholder RunState type.
I added the RunState type in #6971 to disconnect clients from the service
plumbing, which they do not need. Now that we have more complete context
plumbing, the lifecycle of a client no longer depends on this type: It serves
as a carrier for a logger, and a Boolean flag for "running" status, neither of
which is used outside of tests.
Logging in particular is defaulted to a no-op logger in all production use.
Arguably we could just remove the logging calls, since they are never invoked
except in tests. To defer the question of whether we should do that or make the
logging go somewhere more productive, I've preserved the existing use here.
Remove use of the IsRunning method that was provided by the RunState, and use
the Start method and context to govern client lifecycle.
Remove the one test that exercised "unstarted" clients. I would like to remove
that method entirely, but that will require updating the constructors for all
the client types to plumb a context and possibly other options. I have deferred
that for now.
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.
This is the interface shared by types that can be used as event data in, for
example, subscriptions via the RPC.
To be compatible with the RPC service, data need to support JSON encoding.
Require this as part of the interface.
The main change here is to use encoding/json to encode and decode RPC
parameters, rather than the custom tmjson package. This includes:
- Update the HTTP POST handler parameter handling.
- Add field tags to 64-bit integer types to get string encoding (to match amino/tmjson).
- Add marshalers to struct types that mention interfaces.
- Inject wrappers to decode interface arguments in RPC handlers.
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 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.
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.
* Rename rpctypes.Context to CallInfo.
Add methods to attach and recover this value from a context.Context.
* Rework RPC method handlers to accept "real" contexts.
- Replace *rpctypes.Context arguments with context.Context.
- Update usage of RPC context fields to use CallInfo.
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.
* 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.
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.
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.
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.
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 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.
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.

- Clean up client implementations.
- Update mocks.
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.
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
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.
