* WIP: switching to fixed offsets for SignBytes
* add version field to sign bytes and update order
* more comments on test-cases and add a tc with a chainID
* remove amino:"write_empty" tag
- it doesn't affect if default fixed size fields ((u)int64) are
written or not
- add comment about int->int64 casting
* update CHANGELOG_PENDING
* update documentation
* add back link to issue #1622 in documentation
* remove JSON tags and add (failing test-case)
* fix failing test
* update test-vectors due to added `Type` field
* change Type field from string to byte and add new type alias
- SignedMsgType replaces VoteTypePrevote, VoteTypePrecommit and adds new
ProposalType to separate votes from proposal when signed
- update test-vectors
* fix remains from rebasing
* use SignMessageType instead of byte everywhere
* fixes from review
* 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.
```
* do not accept blocks with negative height
* update changelog and spec
* nanos precision for test genesis time
* Fix failing test (#2607)
* switch to amino for SignBytes and add Reply with error message
- currently only Vote is done
* switch Reply type in socket for other messages
- add error description on error
* add TODOs regarding error handling
* address comments from peer review session (thx @xla)
- contains all changes besides the test-coverage / error'ing branches
* increase test coverage:
- add tests for each newly introduced error'ing code path
* return error if received wrong response
* add test for wrong response branches (ErrUnexpectedResponse)
* update CHANGELOG_PENDING and related documentation (spec)
* fix typo: s/CanonicallockID/CanonicalBlockID
* fixes from review
* docs: link consensus to blockchain spec. closes#2422
* docs: deprecate research section. closes#2401
* docs: fix some links
* docs: fix some markdown lists
* docs: fix more links
* ungitignore
* add docs/.vuepress to enable local builds
* config.js needs to be here, one less step
* docs: make spec in sidebar nicer
* docs: local build instructions
* follow up to removing some consensus params Refs #2382
* change args type to int64 in state#makeParams
* make valsCount and evidenceCount ints again
* MaxEvidenceBytesPerBlock: include magic number in godoc
* [spec] creating a proposal
* test state#TxFilter
* panic if MaxDataBytes is less than 0
* fixes after review
* use amino#UvarintSize to calculate overhead
0c74291f3b/encoder.go (L85-L90)
* avoid cyclic imports
* you can do better Go, come on
* remove testdouble package
* Make mempool aware of MaxGas requirement
* update spec
* Add tests
* Switch GasWanted from kv store to persistent kv store
* Fix typo in test name
* switch back to using kvstore, not persistent kv store
* better overview section
* section on tags
* remove notes about state/concurrency from CheckTx
* incorporate feedback from #2249
* explain how validator set updates effect future blocks
* addr_book_strick=false on local nets
* link to spec
* spec: remove TODO, see #1749 instead
* spec: make issues from TODOs
* update docs on addr_book_strict option
* 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
* [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
This now uses one hkdf on the X25519 shared secret to create
a key for the sender and receiver.
The hkdf call is now just called upon the computed shared
secret, since the shared secret is a function of the pubkeys.
The nonces now start at 0, as we are using chacha as a stream
cipher, and the sender and receiver now have different keys.
Currently the top level directory contains basically all of the code
for the crypto package. This PR moves the crypto code into submodules
in a similar manner to what `golang/x/crypto` does. This improves code
organization.
