* Completed draft implementation of witness JSON-RPC endpoints for portal network bridge.
* Updated Nimbus RPC configuration to support enabling experimental endpoints.
* Moved witness verification tests.
* Added json test for getProof.
* Added main procs to new tests to fix test suite.
* Added getBlockWitness test to blockchain json test suite.
* Added tests for experimental RPC endpoints and improved the API to support returning state proofs from before or after block execution.
* Correctly rollback transaction in getBlockWitness proc.
* Improve logging and logging options in Fluffy
- Allow selection of log format, including:
- JSON
- automatic selection based on tty
- Allow log levels per topic configured on cli
* Somewhat tighten error handling
why:
Zombie state is invoked when the current peer turns out to be useless
for further communication. While there is a chance to further talk
to a peer about another topic (aka healing) after some protocol failure,
it makes no sense to do so after a network problem.
The latter state is explained bu the `peerDegraded` flag that goes
together with the `zombie` state flag. A degraded peer is dropped
immediately.
* Remove `--sync-mode=snapCtx` option, always start snap in recovery mode
why:
No need for a snap sync option without recovery mode, can be achieved
by deleting the database.
* Code cosmetics, typos, prettify logging, debugging helper, etc.
* Split off snap sync sub-mode handler into separate modules
details:
The original `worker.nim` source has become a multiplexer for several
snap sync sub-modes `full` and `snap`. The source modules of the
incarnations of a particular sync sub-mode are places into the
`worker/play` directory.
* Update ticker for snap and full sync logging
* Clean up some function prototypes
why:
Simplify polymorphic prototype variances for easier maintenance.
* Fix fringe condition crash when importing bogus RLP node
why:
Accessing non-list RLP entry as a list causes `Defect`
* Fix left boundary proof at range extractor
why:
Was insufficient. The main problem was that there was no unit test for
the validity of the generated left boundary.
* Handle incomplete left boundary proofs early
why:
Attempt to do it later leads to overly complex code in order to prevent
looping when the same peer repeats to send the same incomplete proof.
Contrary, gaps in the leaf sequence can be handled gracefully with
registering the gaps
* Implement a manual pivot setup mechanism for snap sync
why:
For a test scenario it is convenient to set the pivot to something
lower than the beacon header from the consensus layer. This does not
need rely on any RPC mechanism.
details:
The file containing the pivot specs is specified by the
`--sync-ctrl-file` option. It is regularly parsed for updates.
* Fix calculation error
why:
Prevent from calculating negative square root
* Enable `snap/1` accounts range service
* Allow to change the garbage collector to `boehm` as a Makefile option.
why:
There is still an unsolved memory corruption problem that might be
related to the standard `gc`. It seemingly goes away if the `gc` is
changed to `boehm`.
Specifying another `gc` on the make level simplifies debugging and
development.
* Code cosmetics
details:
* updated exception annotations
* extracted `worker_desc.nim` from `full/worker.nim`
* etc.
* Implement option to state a sync modifier file
why:
This allows to specify extra sync type specific options which might
change over time. This file is regularly checked for updates.
* Implement a threshold when to suspend full syncing
why:
For a test scenario, a full sync beep may work as a local snap server.
There is no need to download the full block chain.
details:
The file containing the pivot specs is specified by the
`--sync-ctrl-file` option. It is regularly parsed for updates.
* Removed some Windows specific unit test annoyances
details:
+ Short put()/get() cycles on persistent database have a race condition
with vendor rocksdb. On a specific (and slow) qemu/win7 a 50ms `sleep()`
in between will mostly do the job (i.e. unless heavy CPU load.) This
issue was not observed on github/ci.
+ Removed annoyances when qemu/Win7 keeps the rocksdb database files
locked even after closing the db. The problem is solved by strictly
using fresh names for each test. No assumption made to be able to
properly clean up. This issue was not observed on github/ci.
* Silence some compiler gossip -- part 7, misc/non(sync or graphql)
details:
Adding some missing exception annotation
* Reduce Nim 1.6 compiler warnings/hints for Fluffy and Nimbus proxy
Mostly raises Defect removals, TaintedString removal and some
unnecessary imports.
Also updating the copyright years alongside.
* Further reduce Nim 1.6 compiler warnings/hints for Nimbus
* Silence some compiler gossip -- part 5, common
details:
Mostly removing redundant imports and `Defect` tracer after switch
to nim 1.6
* Silence some compiler gossip -- part 6, db, rpc, utils
details:
Mostly removing redundant imports and `Defect` tracer after switch
to nim 1.6
* Silence some compiler gossip -- part 7, randomly collected source files
details:
Mostly removing redundant imports and `Defect` tracer after switch
to nim 1.6
* Silence some compiler gossip -- part 8, assorted tests
details:
Mostly removing redundant imports and `Defect` tracer after switch
to nim 1.6
* Clique update
why:
More impossible exceptions (undoes temporary fix from previous PR)
* Cosmetics, update logger `topics`
* Clean up sync/start methods in nimbus
why:
* The `protocols` list selects served (as opposed to sync) protocols only.
* The `SyncMode.Default` object is allocated with the other possible sync
mode objects.
* Add snap service stub to `nimbus`
* Provide full set of snap response handler stubs
* Bicarb for the latest CI hiccup
why:
Might be a change in the CI engine for MacOS.
* Stop negotiating pivot if peer repeatedly replies w/usesless answers
why:
There is some fringe condition where a peer replies with legit but
useless empty headers repetely. This goes on until somebody stops.
We stop now.
* Rename `missingNodes` => `sickSubTries`
why:
These (probably missing) nodes represent in reality fully or partially
missing sub-tries. The top nodes may even exist, e.g. as a shallow
sub-trie.
also:
Keep track of account healing on/of by bool variable `accountsHealing`
controlled in `pivot_helper.execSnapSyncAction()`
* Add `nimbus` option argument `snapCtx` for starting snap recovery (if any)
also:
+ Trigger the recovery (or similar) process from inside the global peer
worker initialisation `worker.setup()` and not by the `snap.start()`
function.
+ Have `runPool()` returned a `bool` code to indicate early stop to
scheduler.
* Can import partial snap sync checkpoint at start
details:
+ Modified what is stored with the checkpoint in `snapdb_pivot.nim`
+ Will be loaded within `runDaemon()` if activated
* Forgot to import total coverage range
why:
Only the top (or latest) pivot needs coverage but the total coverage
is the list of all ranges for all pivots -- simply forgotten.
* Error return in `persistBlocks()` on initial `VmState` roblem
why:
previously threw an exception
* Updated sync mode option
why:
using enum rather than bool => space for more
* Added sync mode `full`, re-factued legacy sync
also:
rebased
* Fix typo (crashes `pesistBlocks()` otherwise)
also:
rebase to master
* Reduce log ticker noise by suppressing duplicate messages
* Clarify staged queue overflow handling
why:
backtrack/re-org mode in `stageItem()` should be detected by both,
the global indicator or the work item where it might have moved into.
also:
rebased
* Added sepolia specs
* temporarily avoid latest `master` branch from `nim-eth1`
why:
Currently does not cleanly compile after the `bearssl` split api update.
* Use type name eth and snap (rather than snap1)
* Prettified snap/eth handler trace messages
* Regrouped sync sources
details:
Snap storage related sources are moved to common directory.
Option --new-sync renamed to --snap-sync
also:
Normalised logging for secondary/non-protocol handlers.
* Merge protocol wrapper files => protocol.nim
details:
Merge wrapper sync/protocol_ethxx.nim and sync/protocol_snapxx.nim
into single file snap/protocol.nim
* Comments cosmetics
* Similar start logic for blockchain_sync.nim and sync/snap.nim
* Renamed p2p/blockchain_sync.nim -> sync/fast.nim
* Squashed snap-sync-preview patch
why:
Providing end results makes it easier to have an overview.
Collected patch set comments are available as nimbus/sync/ChangeLog.md
in chronological order, oldest first.
* Removed some cruft and obsolete imports, normalised logging
* Enable JWT authentication for websockets
details:
Currently, this is optional and only enabled when the jwtsecret option
is set.
There is a default mechanism to generate a JWT secret if it is not
explicitly stated. This mechanism is currently unused.
* Make JWT authentication compulsory for websockets
* Fix unit test entry point + cosmetics
* Update JSON-RPC link
* Improvements as suggested by Mamy
* dist: precompiled binaries and Docker images
The builds are reproducible, the binaries are portable and statically link librocksdb.
This took some patching. Upstream PR: https://github.com/facebook/rocksdb/pull/9752
32-bit ARM is missing as a target because two different GCC versions
fail with an ICE when trying to cross-compile RocksDB. Using Clang
instead is too much trouble for a platform that nobody should be using
anyway.
(Clang doesn't come with its own target headers and libraries, can't be
easily convinced to use the ones from GCC, so it needs an fs image from
a 32-bit ARM distro - at which point I stopped caring).
* CI: disable reproducibility test
* Rearrange/rename test_kintsugu => test_custom_network
why:
Debug, fix and test more general problems related to running
nimbus on a custom network.
* Update UInt265/Json parser for --custom-network command line option
why:
As found out with the Kintsugi configuration, block number and balance
have the same Nim type which led to misunderstandings. This patch makes
sure that UInt265 encoded string values "0x11" decodes to 17, and "b"
and "11" to 11.
* Refactored genesis.toBlock() => genesis.toBlockHeader()
why:
The function toBlock(g,db) may return different results depending on
whether the db descriptor argument is nil, or initialised. This is due
to the db.config data sub-descriptor which may give various outcomes
for the baseFee field of the genesis header.
Also, the version where db is non-nil initialised is used internally
only. So the public rewrite toBlockHeader() that replaces the toBlock()
function expects a full set of NetworkParams.
* update comments
* Rename toBlockHeader() => toGenesisHeader()
why:
Polymorphic prototype used for BaseChainDB or NetworkParams argument.
With a BaseChainDB descriptor argument, the name shall imply that the
header is generated from the config fields rather than fetched from
the database.
* Added command line option --static-peers-file
why:
Handy feature to keep peer nodes in a file, similar to the
--bootstrap-file option.
Includes a simple test harness for the merge interop M1 milestone
This aims to enable connecting nimbus-eth2 to nimbus-eth1 within
the testing protocol described here:
https://github.com/status-im/nimbus-eth2/blob/amphora-merge-interop/docs/interop_merge.md
To execute the work-in-progress test, please run:
In terminal 1:

- Remove the `--evm` option on non-EVMC builds.
`when` around an option doesn't work with confutils; it fails to compile.
Workaround that by setting the `ignore` pragma on EVMC-specific options.
(Thanks @jangko for that new pragma). I prefer this to a solution which
moves the whole option's pragma elsewhere, especially if we add more options.
- Improve the help text, so that it shows the standard library extension on
each target platform (or none if on another platform).
- Undo b3f21bf4 "add missing evmc_enabled conditional compilation in
evmc_dynamic_loader". Move the conditional to `nimbus.nim`, and take more
care there to only use the loader function in EVMC builds.
It's ok to just not include this EVMC-only module (like some other EVMC
modules), rather than making the module itself a bit broken: Without this
change, it references a function that's not imported or linked to, and it
only links because there is no call sequence reaching that function.

- `network` and `discovery` got additional longDesc,
the help text now become more descriptive.
- `networkId` and `networkParams` now is ignored by confutils
and become ordinary fields of NimbusConf.
This patch adds:
- Load and use a third-party EVM in a shared library, instead of Nimbus EVM.
- New option `--evm` to specify which library to load.
- The library and this loader conforms to the [EVMC]
(https://evmc.ethereum.org/) 9.x specification.
Any third-party EVM which is compatible with EVMC version 9.x and supports EVM1
contract code will be accepted. The operating system's shared library format
applies. These are `.so*` files on Linux, `.dll` files on Windows and `.dylib`
files on Mac.
The alternative EVM can be selected in two ways:
- Nimbus command line option `--evm:<path>`.
- Environment variable `NIMBUS_EVM=<path>`.
The reason for an environment variable is this allows all the test programs to
run with a third-party EVM as well. Some don't parse command line options.
There are some limitations to be aware of:
- The third-party EVM must use EVMC version 9.x, no other major version.
EVMC 9.x supports EIP-1559 / London fork and older transactions.
- Nested `*CALL` and `CREATE*` operations don't use the third-party EVM yet.
These call the built-in Nimbus EVM. This mixing of different EVMs between
levels is explicitly allowed in specs, so there is no problem doing it.
- The third-party EVM doesn't need to support precompiles, because those are
nested calls, which use the built-in Nimbus EVM.
- Third-party EVMs execute contracts correctly, but fail the final `rootHash`
match. The reason is that some account state changes, which are correct, are
currently inside the Nimbus EVM and need to be moved to EVMC host logic.
*This is a known work in progress*. The EVM execution itself is fine.
Test results using "evmone" third-party EVM:
- [evmone](https://github.com/ethereum/evmone) has been tested. Only on
Linux but it "should" work on Windows and Mac equally well.
- [Version 0.8.1](https://github.com/ethereum/evmone/releases/tag/v0.8.1) was
used because it is compatible with EVMC 9.x, which is required for the
EIP-1559 / London fork, which Nimbus supports. Version 0.8.0 could be used
but it looks like an important bug was fixed in 0.8.1.
- evmone runs fine and the trace output looks good. The calls and arguments
are the same as the built-in Nimbus EVM for tests that have been checked
manually, except evmone skips some calls that can be safely skipped.
- The final `rootHash` is incorrect, due to the *work in progress* mentioned
above which is not part of the evmone execution. Due to this, it's possible
to try evmone and verify expected behaviours, which also validates our own
EVMC implementation, but it can't be used as a full substitute yet.

this is a preparation for migration to confutils based config
although there is still some getConfiguration usage in tests code
it will be removed after new config arrived
