* docs: goleveldb is much more stable now
Refs https://github.com/syndtr/goleveldb/issues/226#issuecomment-682495490
* rpc/core/events: make sure WS client receives every event
previously, if the write buffer was full, the response would've been
lost without any trace (log msg, etc.)
* rpc/jsonrpc/server: set defaultWSWriteChanCapacity to 1
Refs #3905Closes#3829
setting write buffer capacity to 1 makes transactions count per block
more stable and also reduces the pauses length by 20s.
before: https://github.com/tendermint/tendermint/issues/3905#issuecomment-681854328 net.Read - 20s
after: net.Read - 0.66s
* rpc/jsonrpc/server: buffer writes and avoid io.ReadAll during read
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#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`.
Using the WebSocket server, when the same client calls multiple time the subscribe method, only the last subscription receives all the events of the previous ones.
example:
subscription1 = tm.event = 'NewBlock'
subscription2 = tm.event = 'Tx'
In this case, subscription2 will receive the new blocks but subscription1 will not.
This came from the WebSocket handler that had the declaration of the rpcrequest moved and so overridden for every request and given in the JSONReq client context (so the id of the subscription was not the right one).
This fixes the issue by simply declaring the rpcrequest inside the loop so every request will create a new object without overwriting the previous one.
* libs/common: refactor libs common 3
- move nil.go into types folder and make private
- move service & baseservice out of common into service pkg

What is done in this PR:
JSONRPCClient: validate that Response.ID matches Request.ID I wanted
to do the same for the WSClient, but since we're sending events as
responses, not notifications, checking IDs would require storing
them in memory indefinitely (and we won't be able to remove them
upon client unsubscribing because ID is different then).
Request.ID is now optional. Notification is a Request without an ID.
Previously "" or 0 were considered as notifications
Remove #event suffix from ID from an event response (partially fixes
#2949) ID must be either string, int or null AND must be equal to
request's ID. Now, because we've implemented events as responses, WS
clients are tripping when they see Response.ID("0#event") !=
Request.ID("0"). Implementing events as requests would require a lot
of time (~ 2 days to completely rewrite WS client and server)
generate unique ID for each request
switch to integer IDs instead of "json-client-XYZ"
id=0 method=/subscribe
id=0 result=...
id=1 method=/abci_query
id=1 result=...
> send events (resulting from /subscribe) as requests+notifications (not
responses)
this will require a lot of work. probably not worth it
* rpc: generate an unique ID for each request
in conformance with JSON-RPC spec
* WSClient: check for unsolicited responses
* fix golangci warnings
* save commit
* fix errors
* remove ID from responses from subscribe
Refs #2949
* clients are safe for concurrent access
* tm-bench: switch to int ID
* fixes after my own review
* comment out sentIDs in WSClient
see commit body for the reason
* remove body.Close
it will be closed automatically
* stop ws connection outside of write/read routines
also, use t.Rate in tm-bench indexer when calculating ID
