* 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.
* 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
* Unit tests to verify calculations based on hard coded constants
why:
Sizes of RLP encoded objects are available at run time only.
* Changed argument order for `hexaryRangeLeafsProof()` prototype
why:
Better to read as a stand-alone function (arguments were optimised
for functional pipelines)
* Run sub-range proof tests for extracted ranges
* Cosmetics
details:
+ Update doc generator
+ Fix key type representation in `hexary_desc` for debugging
+ Redefine `isImportOk()` as template for better `check()` line reporting
* Fix fringe condition when interpolating Merkle-Patricia tries
details:
Small change with profound effect fixing some pathological condition
that haunted the unit test set on large data sers. There is still one
condition left which might well be due to an incomplete data set.
* Unit test proof nodes for node range extractor
* Unit tests to run on full extraction set
why:
Left over from troubleshooting, range length was only 5
* 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)
* Silence some compiler gossip -- part 1, tx_pool
details:
Mostly removing redundant imports and `Defect` tracer after switch
to nim 1.6
* Silence some compiler gossip -- part 2, clique
details:
Mostly removing redundant imports and `Defect` tracer after switch
to nim 1.6
* Silence some compiler gossip -- part 3, misc core
details:
Mostly removing redundant imports and `Defect` tracer after switch
to nim 1.6
* Silence some compiler gossip -- part 4, sync
details:
Mostly removing redundant imports and `Defect` tracer after switch
to nim 1.6
* Clique update
why:
Missing exception annotation
* Update comments and test noise
* Fix boundary proofs
why:
Where neither used in production, nor unit tested. For production, other
methods apply to test leaf range integrity directly based of the proof
nodes.
* Added `hexary_range()`: interval range + proof extractor
details:
+ Will be used for `snap/1` protocol handler
+ Unit tests added (also for testing left boundary proof)
todo:
Need to verify completeness of proof nodes
* Reduce some nim 1.6 compiler noise
* Stop unit test gossip for ci tests
* Updated to the latest nim-eth, nim-rocksdb, nim-web3
* Bump nimbus-eth2 module and fix related issues
Temporarily disabling Portal beacon light client network as it is
a lot of copy pasted code that did not yet take into account
forks. This will require a bigger rework and was not yet tested
in an actual network anyhow.
* More nimbus fixes after module bumps

Two unresolved items currently:
- Three tests that are temporarily disabled as they fail in the
macro_assembler code, which seems to be due to an ambigious
identifier Stop (Ops and chronos ServerCommand enum).
- i386 CI disabled as it fails at Nim compilation already. Failed
tests where already ignored for this target.
* Extracted RocksDB timing unit tests into separate file
why:
make space for more in main module :)
* Extracted `inspectionRunner()` unit tests into separate file
why:
make space for more in main module :)
* Extracted `storagesRunner()` unit tests into separate file
why:
make space for more in main module :)
* Extracted pivot checkpoint store/retrieval unit tests into separate file
why:
make space for more in main module :)
* Extract helper functions into separate source file
* Extracted account import unit tests into separate file
why:
make space for more in main module :)
* Rename `test_decompose()` => `test_NodeRangeDecompose()`
why:
There will be more functions with `test_NodeRange` prefix.
* 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.
* Simplify pivot update
why:
No need to fetch the pivot header from the network when it can be
be made available in the ivot cache
also:
Keep `txPool` update disabled while syncing
* Cosmetics, tune down some logging noise
* Support `snap/1` without `eth/6?`
why:
Eth is not needed here.
* Snap is an (optional) extension of `eth`
so:
It it must be supported somehow. Nevertheless it will be currently
unused in the snap syncer.
* Register external beacon stream header
why:
This will be used to sync the peers against.
* Update total coverage book-keeping for 100% roll-over
details:
Provide commonly available/used function
* Replace best pivot by beacon stream tracker
details:
Beacon stream header cache will be updated by external chain monitor via
RPC. This cached header will then be used to sync the pivot.
why:
Some peers reconnect recurrently after dialogue was found useless. The
reconnect loop protection was in place already, albeit insufficient.
also:
Some updates to allow setting previously constant parameters at run
time.
* Simplify accounts healing threshold management
why:
Was over-engineered.
details:
Previously, healing was based on recursive hexary trie perusal.
Due to "cheap" envelope decomposition of a range complement for the
hexary trie, the cost of running extra laps have become time-affordable
again and a simple trigger mechanism for healing will do.
* Control number of dangling result nodes in `hexaryInspectTrie()`
also:
+ Returns number of visited nodes available for logging so the maximum
number of nodes can be tuned accordingly.
+ Some code and docu update
* Update names of constants
why:
Declutter, more systematic naming
* Re-implemented `worker_desc.merge()` for storage slots
why:
Provided as proper queue management in `storage_queue_helper`.
details:
+ Several append modes (replaces `merge()`)
+ Added third queue to record entries currently fetched by a worker. So
another parallel running worker can safe the complete set of storage
slots in as checkpoint. This was previously lost.
* Refactor healing
why:
Simplify and remove deep hexary trie perusal for finding completeness.
Due to "cheap" envelope decomposition of a range complement for the
hexary trie, the cost of running extra laps have become time-affordable
again and a simple trigger mechanism for healing will do.
* Docu update
* Run a storage job only once in download loop
why:
Download failure or rejection (i.e. missing data) lead to repeated
fetch requests until peer disconnects, otherwise.
