The `pyrmont` testnet has been discontinued.
For experiments, it's still possible to run pyrmont nodes by passing a
genesis/config, but this PR removes the bundled `--network:pyrmont`
option.
* update docs
* remove empty docs
* remove obsolete `eth2-stats` page
This file is not actually used / useful - should metadata persistence
support be added in the future, it needs to be done with a new file such
that downgrades, that have the TODO logic unimplemented, don't break.
The pre-release light client sync protocol defines additional Req/Resp
messages to be made available when `--serve-light-client-data` is set.
This patch extends the `{.libp2pProtocol.}` pragma with an optional
parameter to tag such light client sync protocol specific messages.
The corresponding protocols are only selectively registered with libp2p.
The `p2p-interface.md` spec defines a `ResourceUnavailable` error to
return in situations where data that exists on the network is locally
unavailable, e.g., when a block within `MIN_EPOCHS_FOR_BLOCK_REQUESTS`
is requested by `BeaconBlocksByRange` but cannot be provided. This patch
adds support for that additional error code.
* Support for Gnosis Chain
`make gnosis-chain-build` will build the Nimbus gnosis chain binary,
stored in `build/nimbus_beacon_node_for_gnosis_chain`.
`make gnosis-chain` will connect to the network.
Other changes:
* Restore compilation with -d:has_genesis_detection
* Removed Makefile target related to testnet0 and testnet1
* Added more debug logging for failed peer handshakes
* Report misconfigured builds which try to embed network metadata
that is incompatible with the currently selected const preset.
* Don't bundle network metadata in minimal builds, as they are not compatible
* harden and speed up block sync
The `GetBlockBy*` server implementation currently reads SSZ bytes from
database, deserializes them into a Nim object then serializes them right
back to SSZ - here, we eliminate the deser/ser steps and send the bytes
straight to the network. Unfortunately, the snappy recoding must still
be done because of differences in framing.
Also, the quota system makes one giant request for quota right before
sending all blocks - this means that a 1024 block request will be
"paused" for a long time, then all blocks will be sent at once causing a
spike in database reads which potentially will see the reading client
time out before any block is sent.
Finally, on the reading side we make several copies of blocks as they
travel through various queues - this was not noticeable before but
becomes a problem in two cases: bellatrix blocks are up to 10mb (instead
of .. 30-40kb) and when backfilling, we process a lot more of them a lot
faster.
* fix status comparisons for nodes syncing from genesis (#3327 was a bit
too hard)
* don't hit database at all for post-altair slots in GetBlock v1
requests
- Request metadata_v2 (altair) by default instead of the v1
- Change the metadata pinger to a 3 failure-then-kick, instead of being time based
- Update kicker scorer to take into account topics which we're not subscribed to, to be sure that we will be able to publish correctly
- Add some metrics to give "fanout" health (in the same spirit of mesh health)
* Harden handling of unviable forks
In our current handling of unviable forks, we allow peers to send us
blocks that come from a different fork - this is not necessarily an
error as it can happen naturally, but it does open up the client to a
case where the same unviable fork keeps getting requested - rather than
allowing this to happen, we'll now give these peers a small negative
score - if it keeps happening, we'll disconnect them.
* keep track of unviable forks in quarantine, to avoid filling it with
known junk
* collect peer scores in single module
* descore peers when they send unviable blocks during sync
* don't give score for duplicate blocks
* increase quarantine size to a level that allows finality to happen
under optimal conditions - this helps avoid downloading the same blocks
over and over in case of an unviable fork
* increase initial score for new peers to make room for one more failure
before disconnection
* log and score invalid/unviable blocks in requestmanager too
* avoid ChainDAG dependency in quarantine
* reject gossip blocks with unviable parent
* continue processing unviable sync blocks in order to build unviable
dag
* docs
* Update beacon_chain/consensus_object_pools/block_pools_types.nim
* add unviable queue test
The new format is based on compressed CSV files in two channels:
* Detailed per-epoch data
* Aggregated "daily" summaries
The use of append-only CSV file speeds up significantly the epoch
processing speed during data generation. The use of compression
results in smaller storage requirements overall. The use of the
aggregated files has a very minor cost in both CPU and storage,
but leads to near interactive speed for report generation.
Other changes:
- Implemented support for graceful shut downs to avoid corrupting
the saved files.
- Fixed a memory leak caused by lacking `StateCache` clean up on each
iteration.
- Addressed review comments
- Moved the rewards and penalties calculation code in a separate module
Required invasive changes to existing modules:
- The `data` field of the `KeyedBlockRef` type is made public to be used
by the validator rewards monitor's Chain DAG update procedure.
- The `getForkedBlock` procedure from the `blockchain_dag.nim` module
is made public to be used by the validator rewards monitor's Chain DAG
update procedure.
* Harden CommitteeIndex, SubnetId, SyncSubcommitteeIndex
Harden the use of `CommitteeIndex` et al to prevent future issues by
using a distinct type, then validating before use in several cases -
datatypes in spec are kept simple though so that invalid data still can
be read.
* fix invalid epoch used in REST
`/eth/v1/beacon/states/{state_id}/committees` committee length (could
return invalid data)
* normalize some variable names
* normalize committee index loops
* fix `RestAttesterDuty` to use `uint64` for `validator_committee_index`
* validate `CommitteeIndex` on ingress in REST API
* update rest rules with stricter parsing
* better REST serializers
* save lots of memory by not using `zip` ...at least a few bytes!
* Tune getLowSubnets
* Also aim for dHigh peers in gossipsub
* Apply suggestions from code review

* fix stack overflow crash in REST/debug/getStateV2
* introduce `ForkyXxx` for generic type matching of `Xxx` across
branches (SomeHashedBeaconState -> ForkyHashedBeaconState et al) -
`Some` is already used for other types of type classes
* consolidate function naming in BeaconChainDB, use some generics

around to resolve circular imports
* remove `ForkedBeaconState`, use `ForkedHashedBeaconState` throughout
(less data shuffling between the types)
* fix several cases of states being stored on stack in tests, causing
random failures on some platforms
* remove reading json support from ncli - this should be ported to the
rest json reading instead (doesn't currently work because stack sizes)
* auto-bump nim-libp2p
* Remove peer info for other peers
Not definitive, just to test the libp2p's unstable branch
* finish up Remove peer info for other peers
* getKey -> getPublicKey
