If a subscriber arrives while the pubsub service is shutting down, the existing
code will return a nil subscription without error. With unlucky timing, this
may lead to a nil indirection panic in the RPC service.
To avoid that problem, make sure that when a subscription fails for this
reason, we report a non-nil error so that the client will detect it and give up
gracefully.
A workaround for #6729. Add parameters to control buffer sizes for
event subscription RPC clients. On some networks, buffering causes
clients to be dropped and/or events to be lost.
For additional context, see the discussion on #7188.
- Add experimental_subscription_buffer_size config parameter
- Add experimental_websocket_write_buffer_size config parameter
- Add experimental_close_on_slow_client config parameter

#5852 fixed an issue with error propagation in `os.EnsureDir()`. However, this function is basically identical to `os.MkdirAll()`, and can be replaced entirely with a call to it. We keep the function for backwards compatibility.
* libs/bits: inline defer and change order of mutexes
Closes#3217
* abci/client: unexpose StopForError func
a) it's not called outside
b) the reason for exposing it in the first place is unclear
c) Stop already exist if someone from outside wants to stop the client
While working on tendermint my colleague @jinmannwong fixed a few of the unit tests that we found to be flaky in our CI. We thought that you might find this useful, see below for comments.
## 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 p2p connections to Protobuf. Supersedes #4800.
gogoproto's `NewDelimitedReader()` uses an internal buffer, which makes it unsuitable for reading individual messages from a shared reader (since any remaining data in the buffer will be discarded). We therefore add a new `protoio` package with an unbuffered `NewDelimitedReader()`. Additionally, the `NewDelimitedWriter()` returns the number of bytes written, and we've added `MarshalDelimited()` and `UnmarshalDelimited()`, to ease migration of existing code.
Amino-compatible JSON encoder/decoder, including bug compatibility. Interface types must be registered via `json.RegisterType()`. Unlike Amino, this allows floats to be encoded/decoded.
Partial fix for #4828, needs code migration.
## Description
In https://github.com/tendermint/tendermint/pull/4466 a new type was created (EventAttribute) that replaced KV.Pair. This made the type Pair deadcode, this pr removes that type.
I don't think a changelog entry is needed since it is not being used anymore. But will add a section to the upgrading.md to let users know that it was replaced
Closes: #XXX
## Description
bech32 is only used in the sdk. I moved Bech32 to the sdk and we can remove it here. Don't think this needs to go into a minor release
Closes: #XXX
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`.
The service logging can be a bit unclear. For example, with state sync it would log:
```
I[2020-04-20|08:40:47.366] Starting StateSync module=statesync impl=Reactor
I[2020-04-20|08:40:47.834] Starting state sync module=statesync
```
Where the first message is the reactor service startup, and the second message is the start of the actual state sync process. This clarifies the first message by changing it to `Starting StateSync service`.
