There are a lot of existing links to the master section of the site, and my
attempts to get a redirector working have so far not succeeded. While it still
makes sense to not publish docs for unreleased code, a 404 is almost certainly
more disruptive than seeing docs for unreleased stuff.
This includes the docs in the build again, but does not add them back to the
selector menu. That allows URLs to resolve but encourages folks to use the
released versions when they have a choice.
I left the redirect for the RPC link in place, since that's still useful.
Updates #7935.
Implement the basic cursor and eventlog types described in ADR 075. Handle
encoding and decoding as strings for compatibility with JSON.
- Add unit tests for the required order and synchronization properties.
- Add hooks for metrics, with one value to be expanded later.
- Update ADR 075 to match the specifics of the implementation so far.
* event: Added Events after evidence validation; evidence: refactored AddEvidence
Added context and Metrics as parameter for the pool constructor
* evidence: pushed event firing into evidence pool and added metrics to represent the size of the evpool
* state: fixed parameters of evpool mock functions
* evidence: added test to confirm events are generated
* Removed obsolete EvidenceEventPublisher interface
* evidence: pool removed error on missing eventbus
Went through #2871, there are several issues, this PR tries to tackle the `HasVoteMessage` with an invalid validator index sent by a bad peer and it prevents the bad vote goes to the peerMsgQueue.
Future work, check other bad message cases and plumbing the reactor errors with the peer manager and then can disconnect the peer sending the bad messages.
I think in the future we should migrate from having our own logging
interface and use our logger directly, which I think would help
obviate this particular problem, but in the mean time, this seems safe.
## Summary
This pull request adds a default set of values to the new Synchrony parameters. These values were chosen by after observation of three live networks: Emoney, Osmosis, and the Cosmos Hub.
For the default Precision value, `505ms` was selected. The reasoning for this is summarized in https://github.com/tendermint/tendermint/issues/7724
For each observed chain, an experimental Message Delay was collected over a 24 hour period and an average over this period was calculated using this data. Values over 10s were considered outliers and treated separately for the average since the majority of observations were far below 10s. The message delay was calculated both for the quorum and the 'full' prevote. Description of the technique for collecting the experimental values can found in #7202. This value is calculated only using timestamps given by processes on the network, so large variation in values is almost certainly due to clock skew among the validator set.
`12s` is proposed for the default MessageDelay value. This value would easily accomodates all non-outlier values, allowing even E-money's 4.25s value to be valid. This would also allow some validators with skewed clocks to still participate without allowing for huge variation in the timestamps produced by the network. Additionally, for the currently listed use-cases of PBTS, such as unbonding period, and light client trust period, the current bounds for these are in weeks. Adding a few seconds of tolerance by default is therefore unlikely to have serious side-effects.
