* more proposer priority tests
- test that we don't reset to zero when updating / adding
- test that same power validators alternate
* add another test to track / simulate similar behaviour as in #2960
* address some of Chris' review comments
* address some more of Chris' review comments
* temporarily pushing branch with the following changes:
The total power might change if:
- a validator is added
- a validator is removed
- a validator is updated
Decrement the accums (of all validators) directly after any of these events
(by the inverse of the change)
* Fix 2960 by re-normalizing / scaling priorities to be in bounds of total
power, additionally:
- remove heap where it doesn't make sense
- avg. only at the end of IncrementProposerPriority instead of each
iteration
- update (and slightly improve)
TestAveragingInIncrementProposerPriorityWithVotingPower to reflect
above changes

* fix tests
* add comment
* update changelog pending & some minor changes
* comment about division will floor the result & fix typo
* Update TestLargeGenesisValidator:
- remove TODO and increase large genesis validator's voting power
accordingly
* move changelog entry to P2P Protocol
* Ceil instead of flooring when dividing & update test
* quickly fix failing TestProposerPriorityDoesNotGetResetToZero:
- divide by Ceil((maxPriority - minPriority) / 2*totalVotingPower)
* fix typo: rename getValWitMostPriority -> getValWithMostPriority
* test proposer frequencies
* return absolute value for diff. keep testing
* use for loop for div
* cleanup, more tests
* spellcheck
* get rid of using floats: manually ceil where necessary
* Remove float, simplify, fix tests to match chris's proof (#3157)
* WIP: tests for #2785
* rebase onto develop
* add Bucky's test without changing ValidatorSet.Update
* make TestValidatorSetBasic fail
* add ProposerPriority preserving fix to ValidatorSet.Update to fix
TestValidatorSetBasic
* fix randValidator_ to stay in bounds of MaxTotalVotingPower
* check for expected proposer and remove some duplicate code
* actually limit the voting power of random validator ...
* fix test
* types: ValidatorSet.Update preserves ProposerPriority
This solves the other issue discovered as part of #2718,
where Accum (now called ProposerPriority) is reset to
0 every time a validator is updated.
* update changelog
* add test
* update comment
* Update types/validator_set_test.go
Co-Authored-By: ebuchman <ethan@coinculture.info>
* set the accum of a new validator to (-total voting power):
- disincentivize validators to unbond, then rebon to reset their
negative Accum to zero
additional unrelated changes:
- do not capitalize error msgs
- fix typo
* review comments: (re)capitalize errors & delete obsolete comments
* More changes suggested by @melekes
* WIP: do not batch clip (#2809)
* substract avgAccum on each iteration
- temporarily skip test
* remove unused method safeMulClip / safeMul
* always substract the avg accum
- temp. skip another test
* remove overflow / underflow tests & add tests for avgAccum:
- add test for computeAvgAccum
- as we substract the avgAccum now we will not trivially over/underflow
* address @cwgoes' comments
* shift by avg at the end of IncrementAccum
* Add comment to MaxTotalVotingPower
* Guard inputs to not exceed MaxTotalVotingPower
* Address review comments:
- do not fetch current validator from set again
- update error message
* Address a few review comments:
- fix typo
- extract variable
* address more review comments:
- clarify 1.125*totalVotingPower == totalVotingPower + (totalVotingPower >> 3)
* review comments: panic instead of "clipping":
- total voting power is guarded to not exceed MaxTotalVotingPower ->
panic if this invariant is violated
* fix failing test
* 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
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.
Ref discussion: https://github.com/tendermint/tendermint/pull/1966Closes#1956
