* rpc: simplify the handling of JSON-RPC request and response IDs
Replace the ID wrapper interface with plain JSON. Internally, the client
libraries use only integer IDs, and the server does not care about the ID
structure apart from checking its validity.
Basic structure of this change:
- Remove the jsonrpcid interface and its helpers.
- Unexport the ID field of request and response.
- Add helpers for constructing requests and responses.
- Fix up usage and tests.
Update the interface of the batch decoder to match the type signature of the
single-response case. The caller provides the outputs, so there is no need to
return them as well.
No functional changes.
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.
* 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.
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.
## 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.
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
This PR wraps the stdlib sync.(RW)Mutex & godeadlock.(RW)Mutex. This enables using go-deadlock via a build flag instead of using sed to replace sync with godeadlock in all files
Closes: #3242
## Description
partially cleanup in preparation for errcheck
i ignored a bunch of defer errors in tests but with the update to go 1.14 we can use `t.Cleanup(func() { if err := <>; err != nil {..}}` to cover those errors, I will do this in pr number two of enabling errcheck.
ref #5059
Migrates the `rpc` package to use new JSON encoder in #4955. Branched off of that PR.
Tests pass, but I haven't done any manual testing beyond that. This should be handled as part of broader 0.34 testing.
