* config: reduce default mempool size
This reduces the mempool size from 100k to 5k. Note that each secp256k1 sig
takes .5ms to compute. Therefore an adversary could previously delay every
node on the network's computation time upon receiving a block by 50 seconds.
This now reduces that ability to being able to only delay each node by 2.5
seconds. This change should be reverted once ABCI recheck is implemented.
* (squash this) fix test
* mempool: Store txs by hash inside of cache
This allows for large cachesizes, without fear of the memory
consumption growing rapidly.
* (squash this) rename hashedTx -> txHash
* update secret connection to use a little endian encoded nonce
* update encoding of chunk length to be little endian, too
* update comment
* Change comment slightly to trigger circelci
* crypto/secp256k1: Fix signature malleability, adopt more efficient encoding
This removes signature malleability per ADR 14, and makes secp match
the encoding in ADR 15.
* (squash this) add lock
* [p2p/pex] connect to more than 10 peers
also, remove DefaultMinNumOutboundPeers because a) I am not sure it's
needed b) it's super confusing
look closely
```
maxPeers := sw.config.MaxNumPeers - DefaultMinNumOutboundPeers
if maxPeers <= sw.peers.Size() {
sw.Logger.Info("Ignoring inbound connection: already have enough peers", "address", inConn.RemoteAddr().String(), "numPeers", sw.peers.Size(), "max", maxPeers)
```
we print maxPeers = config.MaxPeers - DefaultMinNumOutboundPeers. So we
may not have enough peers even though we say we have enough.
Refs #2130
* update spec
* replace MaxNumPeers with MaxNumInboundPeers/MaxNumOutboundPeers
Refs #2130
* update changelog
* make max rpc conns formula visible to users
* update spec
* docs: note max outbound peers excludes persistent
* clist: Speedup detachNext() and detachPrev()
We used unnecessary function calls, defers, and extra mutexes.
These are not our friends for writing fast code in our libs.
* Remove more defers from clist functions
* Add more benchmarks
