This continues the push of plumbing contexts through tendermint. I
attempted to find all goroutines in the production code (non-test) and
made sure that these threads would exit when their contexts were
canceled, and I believe this PR does that.
The 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.
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
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.
Closes#4837
- `/block_results`
before:
failed to update light client to 7: failed to obtain the header #7: signed header not found
after:
We can't return the latest block results because we won't be able to
prove them. Return the results for the previous block instead.
- /block_results?height=X`

Closes#4603
Commands used (VIM):
```
:args `rg -l errors.Wrap`
:argdo normal @q | update
```
where q is a macros rewriting the `errors.Wrap` to `fmt.Errorf`.
We first introduced auto-update as a separate struct AutoClient, which
was wrapping Client and calling Update periodically.
// AutoClient can auto update itself by fetching headers every N seconds.
type AutoClient struct {
base *Client
updatePeriod time.Duration
quit chan struct{}
trustedHeaders chan *types.SignedHeader
errs chan error
}
// NewAutoClient creates a new client and starts a polling goroutine.
func NewAutoClient(base *Client, updatePeriod time.Duration) *AutoClient {
c := &AutoClient{
base: base,
updatePeriod: updatePeriod,
quit: make(chan struct{}),
trustedHeaders: make(chan *types.SignedHeader),
errs: make(chan error),
}
go c.autoUpdate()
return c
}
// TrustedHeaders returns a channel onto which new trusted headers are posted.
func (c *AutoClient) TrustedHeaders() <-chan *types.SignedHeader {
return c.trustedHeaders
}
// Err returns a channel onto which errors are posted.
func (c *AutoClient) Errs() <-chan error {
return c.errs
}
// Stop stops the client.
func (c *AutoClient) Stop() {
close(c.quit)
}
func (c *AutoClient) autoUpdate() {
ticker := time.NewTicker(c.updatePeriod)
defer ticker.Stop()
for {
select {
case <-ticker.C:
lastTrustedHeight, err := c.base.LastTrustedHeight()
if err != nil {
c.errs <- err
continue
}
if lastTrustedHeight == -1 {
// no headers yet => wait
continue
}
newTrustedHeader, err := c.base.Update(time.Now())
if err != nil {
c.errs <- err
continue
}
if newTrustedHeader != nil {
c.trustedHeaders <- newTrustedHeader
}
case <-c.quit:
return
}
}
}
Later we merged it into the Client itself with the assumption that most clients will want it.
But now I am not sure. Neither IBC nor cosmos/relayer are using it. It increases complexity (Start/Stop methods).
That said, I think it makes sense to remove it until we see a need for it (until we better understand usage behavior). We can always introduce it later 😅. Maybe in the form of AutoClient.

* lite2: move AutoClient into Client
Most of the users will want auto update feature, so it makes sense to
move it into the Client itself, rather than having a separate
abstraction (it makes the code cleaner, but introduces an extra thing
the user will need to learn).
Also, add `FirstTrustedHeight` func to Client to get first trusted height.

* require block.Time of the fist block to be genesis time
Refs #2587:
```
We only start validating block.Time when Height > 1, because there is no
commit to compute the median timestamp from for the first block. This
means a faulty proposer could make the first block with whatever time
they want.
Instead, we should require the timestamp of block 1 to match the genesis
time.
I discovered this while refactoring the ValidateBlock tests to be
table-driven while working on tests for #2560.
