Allow for the Fluffy Portal bridge to inject receipts. This
requires a web3 endpoint to be provided, and currently only
Alchemy is supported due to the used JSON-RPC endpoint.
* Update nearby/neighbour leaf nodes finder
details:
Update return error codes so that in the case that there is no more
leaf node beyond the search direction, the particular error code
`NearbyBeyondRange` is returned.
* Compile largest interval range containing only this leaf point
why:
Will be needed in snap sync for adding single leaf nodes to the range
of already allocated nodes.
* Reorg `hexary_inspect.nim`
why:
Merged the nodes collecting algorithm for persistent and in-memory
into a single generic function `hexary_inspect.inspectTrieImpl()`
* Update fetching accounts range failure handling in `rangeFetchAccounts()`
why:
Rejected response leads now to fetching for another account range. Only
repeated failures (or all done) terminate the algorithm.
* Update accounts healing
why:
+ Fixed looping over a bogus node response that could not inserted into
the database. As a solution, these nodes are locally registered and not
asked for in this download cycle.
+ Sub-optimal handling of interval range for a healed account leaf node.
Now the maximal range interval containing this node is registered as
processed which leafs to de-fragementation of the processed (and
unprocessed) range list(s). So *gap* ranges which are known not to
cover any account leaf node are not asked for on the network, anymore.
+ Sporadically remove empty interval ranges (if any)
* Update logging, better variable names
It is only (mostly) a skeleton, not further developed and not
used. It is unlikely the way forward either when further
developing the Portal state network.
t8n: a silly bug contract address generator, should use original
tx nonce instead of read the nonce from sender address in state db.
Although in EVM contract address generated by reading nonce from state db
is correct, outside EVM that nonce value might have been modified,
thus generating incorrect contract address.
accounts cache: when clearing account storage, the originalValue
cache is not cleared, only the storageRoot set to empty storage root,
this will cause getStorage and getCommitedStorage return wrong value
if the originalValue cache contains old value.
* Redesign snap1 message GetTrieNodes argument prototypes
why:
A list of sub-objects `seq[SnapTriePath]` is more intuitive to work with
than an opaque definition `seq[seq[Blob]]` because the inner object
`SnapTriePath` object has a dedicated inner structure (for how to
interprete `seq[Blob]`.)
* Collect some public constants into `constants.nim` file
* Reorg `hexary_paths.nim`
why:
+ Collecting nodes following a partial path properly ending at an
extension node failed to collect this last node.
+ Merged the nodes collecting algorithm for persistent and in-memory
into a single generic function `hexary_paths.rootPathExtend()`
info:
Extracted common tasks to `hexary_nodes_helper.nim`
* Implement `StorageRanges` message handler for snap/1 protocol
now macro assembler support merge fork, shanghai, etc without using ugly hack.
also each assembler test have their own `setup` section that can access
`vmState` and perform various custom setup.
simplify EVM and delegete those things to accounts cache.
also no more manual state clearing, accounts cache will be
responsible for both collecting touched account and perform
state clearing.
* Gwei conversion should use u256 because u64 can overflow.
* Make withdrawals follow the EIP-158 state-clearing rules.
(i.e. Empty accounts should be deleted.)
* Allow the zero address in normalizeNumber.
(Necessary for one of the new withdrawals-related tests.)
* Another fix with a withdrawals-related test.
* Add state root to node steps path register `RPath` or `XPath`
why:
Typically, the first node in the path register is the state root. There
are occasions, when the path register is empty (i.e. there are no node
references) which typically applies to a zero node key.
In order to find the next node key greater than zero, the state root is
is needed which is now part of the `RPath` or `XPath` data types.
* Extracted hexary tree debugging functions into separate files
* Update empty path fringe case for left/right node neighbour
why:
When starting at zero, the node steps path register would be empty. So
will any path that is before the fist non-zero link of a state root (if
it is a `Branch` node.)
The `hexaryNearbyRight()` or `hexaryNearbyLeft()` function required a
non-zero node steps path register. Now the first node is to be advanced
starting at the first state root link if necessary.
* Simplify/reorg neighbour node finder
why:
There was too mach code repetition for the cases
* persistent or in-memory database
* left or right move
details:
Most algorithms apply for persistent and in-memory alike. Using
templates/generic functions most of these algorithms can be stated
in a unified way
* Update storage slots snap/1 handler
details:
Minor changes to be more debugging friendly.
* Fix detection of full database for snap sync
* Docu: Snap sync test & debugging scenario
* Gwei conversion should use u256 because u64 can overflow.
* Make withdrawals follow the EIP-158 state-clearing rules.
(i.e. Empty accounts should be deleted.)
* Allow the zero address in normalizeNumber.
(Necessary for one of the new withdrawals-related tests.)
* Handle last/all node(s) proof conditions at leaf node extractor
detail:
Flag whether the maximum extracted node is the last one in database
No proof needed if the full tree was extracted
* Clean up some helpers & definitions
details:
Move entities to more plausible locations, e.g. `Account` object need
not be dealt with in the range extractor as it applies to any kind of
leaf data.
* Fix next/prev database walk fringe condition
details:
First check needed might be for a leaf node which was done too late.
* Homogenise snap/1 protocol function prototypes
why:
The range arguments `origin` and `limit` data types differed in various
function prototypes (`Hash256` vs. `openArray[byte]`.)
* Implement `GetStorageRange` handler
* Implement server timeout for leaf node retrieval
why:
This feature leaves control on the server for probably costly action
invoked by the network
* Implement maximal reply size for snap service
why:
This feature leaves control on the server for probably costly action
invoked by the network.
* Part of EIP-4895: add withdrawals processing to block processing.
* Refactoring: extracted the engine API handler bodies into procs.
Intending to implement the V2 versions next. (I need the bodies to be
in separate procs so that multiple versions can use them.)
* Working on Engine API changes for Shanghai.
* Updated nim-web3, resolved ambiguity in Hash256 type.
* Updated nim-eth3 to point to master, now that I've merged that.
* I'm confused about what's going on with engine_client.
But let's try resolving this Hash256 ambiguity.
* Still trying to fix this conflict with the Hash256 types.
* Does this work now that nimbus-eth2 has been updated?
* Corrected blockValue in getPayload responses back to UInt256.
c834f67a37
* Working on getting the withdrawals-related tests to pass.
* Fixing more of those Hash256 ambiguities.
(I'm not sure why the nim-web3 library introduced a conflicting type
named Hash256, but right now I just want to get this code to compile again.)
* Bumped a couple of libraries to fix some error messages.
* Needed to get "make fluffy-tools" to pass, too.
* Getting "make nimbus_verified_proxy" to build.
* 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
why:
The peer manager runs concurrently to the discovery scheme. So the p2p
peer observer will also present `peer` non-static entries. Previously,
this peer manager throw an assert defect when this happened.
* Renaming androgynous sub-object names according to where they belong
why:
These objects are not explicitly dealt with. They give meaning to
some generic wrapper objects. Naming them after their origin may
help troubleshooting.
* Redefine proof nodes list data type for `snap/1` wire protocol
why:
The current specification suffered from the fact that the basic data
type for a proof node is an RLP encoded hexary node. This slightly
confused the encoding/decoding magic.
details:
This is the second attempt, now wrapping the `seq[Blob]` into a
wrapper object of `seq[SnapProof]` for a distinct alias sequence.
In the previous attempt, `SnapProof` was a wrapper object holding the
`Blob` with magic applied to the `seq[]`. This needed the `append`
mixin to strip the outer wrapper that was applied to the `Blob` already
when it was passed as argument.
* Fix some prototype inconsistency
why:
For easy reading, `getAccountRange()` handler return code should
resemble the `accoundRange()` anruments prototype.
* 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.
* Bump nimbus-eth2 and fix beacon LC related changes
* Disable local_testnet test in CI
Latest version is no longer compatible with the old nightlies that are being downloaded for the test
* Fix locked database file annoyance with unit tests on Windows
why:
Need to clean up old files first from previous session as files remain
locked despite closing of database.
* Fix initialisation order
detail:
Apparently this has no real effect as the ticker is only initialised
here but started later.
This possible bug has been in all for a while and was running with the
previous compiler and libraries.
* Better naming of data fields for sync descriptors
details:
* BuddyRef[S,W]: buddy.data -> buddy.only
* CtxRef[S]: ctx.data -> ctx.pool
* Refactoring in preparation for time-based forking.
* Timestamp-based hard-fork-transition.
* Workaround SideEffect issue / compiler bug for both failing locations in Portal history code

* Redefine `seq[Blob]` => `seq[SnapProof]` for `snap/1` protocol
why:
Proof nodes are traded as `Blob` type items rather than Nim objects. So
the RLP transcoder must not extra wrap proofs which are of type
seq[Blob]. Without custom encoding one would produce a
`list(blob(item1), blob(item2) ..)` instead of `list(item1, item2 ..)`.
* Limit leaf extractor by RLP size rather than number of items
why:
To be used serving `snap/1` requests, the result of function
`hexaryRangeLeafsProof()` is limited by the maximal space
needed to serialise the result which will be part of the
`snap/1` repsonse.
* Let the range extractor `hexaryRangeLeafsProof()` return RLP list sizes
why:
When collecting accounts, the size oft the accounts list when encoded
as RLP is continually updated. So the summed up value is available
anyway. For the proof nodes list, there are not many (~ 10) so summing
up is not expensive here.
* 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
* Silence some compiler gossip -- part 6, evm
details:
Adding some missing exception annotation
* Update evmc cases
why:
were previously missing
* Increase Windows stack needed to run EVMC unit tests
why:
After annotating functions to trace exceptions some unit tests started
to fail on Windows without clear error report.
EVMC works recursively and now there seems to be a stack problem
reported by the nim compiler. Increasing the NIM stack ass sugessted by
NIM (using -d:nimCallDepthLimit=###) had some effect but no clear
solution.
Note that this patch set unrolls some NIM compiler settings
