* CoreDb: Remove crufty second/off-site KVT
why:
Was used to allow late `Clique` to store directly to disk
* CoreDb: Remove prune flag related functionality
why:
Is completely legacy stuff
* CoreDb: Remove dependence on legacy API (tests unsupported yet)
why:
Does not fully support Aristo
* Re-factoring `state_db` using new API
details:
Only minimum changes needed to compile `nimbus`
* Update tests and aux modules
* Turn off legacy API and remove `distinct_tries`
comment:
The legacy API has now cruft status, will be removed soon
* Fix copyright years
* Update rpc for verified proxy

Co-authored-by: Jacek Sieka <jacek@status.im>
* Remove cruft
* Docu/code cosmetics
* Aristo: Update `forkBase()`
why:
Was not up to the job
* Update/correct tracer for running against `Aristo`
details:
This patch makes sure that before creating a new `BaseVMState` the
`CoreDb` context is adjusted to accommodate for the state root that
is passed to the `BaseVMState` constructor.
* CpreDb+legacy: Always return current context with `ctxFromTx()`
why:
There was an experimental setting trying to find the node with the
proper setting in the KVT (not the hexary tie layer) which currently
does not work reliable, probably due to `Ledger` caching effects.
* Aristo: Provide descriptor fork based on search in transaction stack
details:
Try to find the tx that has a particular pair `(vertex-id,hash-key)`,
and by extension try filter and backend if the former fails.
* Cleanup & docu
* CoreDb+Aristo: Implement context re-position to earlier in-memory state
why:
It is a easy way to explore how there can be concurrent access to the
same backend storage DB with different view states. This one can access
an earlier state from the transaction stack.
* CoreDb+Aristo: Populate tracer stubs with real functionality
* Update `tracer.nim` to new API
why:
Legacy API does not sufficiently support `Aristo`
* Fix logging problems in tracer
details:
Debug logging turned off by default
* Fix function prototypes
* Add Copyright header
* Add tables import
why:
For older compiler versions on CI
* Aristo: Remove cruft
* Prettifying profile statistics printing & source code cosmetics
* Aristo/Kvt: API tools update
* CoreDb: Corrections, mostly API related
* CoreDb: Changed the tracer `logDb()` result
why:
Only the key-value table is used from the logger database
* CoreDb: Update legacy tracer
why:
The `contains()` directive did not correspond to `0 < get().len`
also:
Copy `CoreDb` meta settings like `trackLegaApi`, `trackNewApi`, etc. to
overlay tracer descriptor
* CoreDb: Extend/update tracer API
why:
Get ready for accommodating `Aristo` tracer
* Fix missing import
why:
Some CI compilers might have (cached?) a different NIM patch level
* Ditto
* Activate `LedgerRef` wrapper for `AccountsCache`
details:
`accounts_cache.nim` methods are indirectly processed by the wrapper
methods from `ledger.nim`.
This works for all sources except `test_state_db.nim` where the source
`accounts_cache.nim` is included (rather than imported) in order to
access objects privy to the very source.
* Provide facility to switch to a preselected `LedgerRef` type
details:
Can be set as suggestion when initialising `CommonRef`
* Update `CoreDb` test suite for better time tracking
details:
+ Allow time logging by pre-defined block intervals
+ Print `CoreDb`/`Ledger`profiling results (if enabled)
* CoreDB: Re-org API
details:
Legacy API internally uses vertex ID for root node abstraction
* Cosmetics: Move some unit test helpers to common sub-directory
* Extract constant from `accouns_cache.nim` => `constants.nim`
* Fix tracer methods
why:
Logger dump data were wrongly dumped from the production database. This
caused an assert exception when iterating over the persistent database
(instead of the memory logger.) This event in turn was enabled after
fixing another inconsistency which just set up an empty iterator. Unit
tests failed to detect that.
* Nimbus folder environment update
details:
* Integrated `CoreDbRef` for the sources in the `nimbus` sub-folder.
* The `nimbus` program does not compile yet as it needs the updates
in the parallel `stateless` sub-folder.
* Stateless environment update
details:
* Integrated `CoreDbRef` for the sources in the `stateless` sub-folder.
* The `nimbus` program compiles now.
* Premix environment update
details:
* Integrated `CoreDbRef` for the sources in the `premix` sub-folder.
* Fluffy environment update
details:
* Integrated `CoreDbRef` for the sources in the `fluffy` sub-folder.
* Tools environment update
details:
* Integrated `CoreDbRef` for the sources in the `tools` sub-folder.
* Nodocker environment update
details:
* Integrated `CoreDbRef` for the sources in the
`hive_integration/nodocker` sub-folder.
* Tests environment update
details:
* Integrated `CoreDbRef` for the sources in the `tests` sub-folder.
* The unit tests compile and run cleanly now.
* Generalise `CoreDbRef` to any `select_backend` supported database
why:
Generalisation was just missed due to overcoming some compiler oddity
which was tied to rocksdb for testing.
* Suppress compiler warning for `newChainDB()`
why:
Warning was added to this function which must be wrapped so that
any `CatchableError` is re-raised as `Defect`.
* Split off persistent `CoreDbRef` constructor into separate file
why:
This allows to compile a memory only database version without linking
the backend library.
* Use memory `CoreDbRef` database by default
detail:
Persistent DB constructor needs to import `db/core_db/persistent
why:
Most tests use memory DB anyway. This avoids linking `-lrocksdb` or
any other backend by default.
* fix `toLegacyBackend()` availability check
why:
got garbled after memory/persistent split.
* Clarify raw access to MPT for snap sync handler
why:
Logically, `kvt` is not the raw access for the hexary trie (although
this holds for the legacy database)
* 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
* Redesign of BaseVMState descriptor
why:
BaseVMState provides an environment for executing transactions. The
current descriptor also provides data that cannot generally be known
within the execution environment, e.g. the total gasUsed which is
available not before after all transactions have finished.
Also, the BaseVMState constructor has been replaced by a constructor
that does not need pre-initialised input of the account database.
also:
Previous constructor and some fields are provided with a deprecated
annotation (producing a lot of noise.)
* Replace legacy directives in production sources
* Replace legacy directives in unit test sources
* fix CI (missing premix update)
* Remove legacy directives
* chase CI problem
* rebased
* Re-introduce 'AccountsCache' constructor optimisation for 'BaseVmState' re-initialisation
why:
Constructing a new 'AccountsCache' descriptor can be avoided sometimes
when the current state root is properly positioned already. Such a
feature existed already as the update function 'initStateDB()' for the
'BaseChanDB' where the accounts cache was linked into this desctiptor.
The function 'initStateDB()' was removed and re-implemented into the
'BaseVmState' constructor without optimisation. The old version was of
restricted use as a wrong accounts cache state would unconditionally
throw an exception rather than conceptually ask for a remedy.
The optimised 'BaseVmState' re-initialisation has been implemented for
the 'persistBlocks()' function.
also:
moved some test helpers to 'test/replay' folder
* Remove unused & undocumented fields from Chain descriptor
why:
Reduces attack surface in general & improves reading the code.
details:
1. The check for cumulativeGasUsed + tx.gasLimit <= header.gasLimit
makes neither sense nor is it part of the Eip1559 specs. Nevertheless
a check tx.gasLimit <= header.gasLimit is added to satisfy some
unit test (see comments in validateTransaction() body.)
2. As a replacement check for the one removed in 1, a check for
cumulativeGasUsed + gasBurned <= header.gasLimit has been added
(see comments in processTransactionImpl() body.)
3. Prototypes for processTransaction() variants have been cleaned up and
commented.
why:
Detail 1. in particular produces an error for tightly packed blocks when
the last tx in the list has a generous gasLimit.
previously, every time the VMState was created, it will also create
new stateDB, and this action will nullify the advantages of cached accounts.
the new changes will conserve the accounts cache if the executed blocks
are contiguous. if not the stateDB need to be reinited.
this changes also allow rpcCallEvm and rpcEstimateGas executed properly
using current stateDB instead of creating new one each time they are called.
* Provide API
details:
API is bundled via clique.nim.
* Set extraValidation as default for PoA chains
why:
This triggers consensus verification and an update of the list
of authorised signers. These signers are integral part of the
PoA block chain.
todo:
Option argument to control validation for the nimbus binary.
* Fix snapshot state block number
why:
Using sub-sequence here, so the len() function was wrong.
* Optional start where block verification begins
why:
Can speed up time building loading initial parts of block chain. For
PoA, this allows to prove & test that authorised signers can be
(correctly) calculated starting at any point on the block chain.
todo:
On Goerli around blocks #193537..#197568, processing time increases
disproportionally -- needs to be understand
* For Clique test, get old grouping back (7 transactions per log entry)
why:
Forgot to change back after troubleshooting
* Fix field/function/module-name misunderstanding
why:
Make compilation work
* Use eth_types.blockHash() rather than utils.hash() in Clique modules
why:
Prefer lib module
* Dissolve snapshot_misc.nim
details:
.. into clique_verify.nim (the other source file clique_unused.nim
is inactive)
* Hide unused AsyncLock in Clique descriptor
details:
Unused here but was part of the Go reference implementation
* Remove fakeDiff flag from Clique descriptor
details:
This flag was a kludge in the Go reference implementation used for the
canonical tests. The tests have been adapted so there is no need for
the fakeDiff flag and its implementation.
* Not observing minimum distance from epoch sync point
why:
For compiling PoA state, the go implementation will walk back to the
epoch header with at least 90000 blocks apart from the current header
in the absence of other synchronisation points.
Here just the nearest epoch header is used. The assumption is that all
the checkpoints before have been vetted already regardless of the
current branch.
details:
The behaviour of using the nearest vs the minimum distance epoch is
controlled by a flag and can be changed at run time.
* Analysing processing time (patch adds some debugging/visualisation support)
why:
At the first half million blocks of the Goerli replay, blocks on the
interval #194854..#196224 take exceptionally long to process, but not
due to PoA processing.
details:
It turns out that much time is spent in p2p/excecutor.processBlock()
where the elapsed transaction execution time is significantly greater
for many of these blocks.
Between the 1371 blocks #194854..#196224 there are 223 blocks with more
than 1/2 seconds execution time whereas there are only 4 such blocks
before and 13 such after this range up to #504192.
* fix debugging symbol in clique_desc (causes CI failing)
* Fixing canonical reference tests
why:
Two errors were introduced earlier but ovelooked:
1. "Remove fakeDiff flag .." patch was incomplete
2. "Not observing minimum distance .." introduced problem w/tests 23/24
details:
Fixing 2. needed to revert the behaviour by setting the
applySnapsMinBacklog flag for the Clique descriptor. Also a new
test was added to lock the new behaviour.
* Remove cruft
why:
Clique/PoA processing was intended to take place somewhere in
executor/process_block.processBlock() but was decided later to run
from chain/persist_block.persistBlock() instead.
* Update API comment
* ditto
* extract unused clique/mining support into separate file
why:
mining is currently unsupported by nimbus
* Replay first 51840 transactions from Goerli block chain
why:
Currently Goerli is loaded but the block headers are not verified.
Replaying allows real data PoA development.
details:
Simple stupid gzipped dump/undump layer for debugging based on
the zlib module (no nim-faststream support.)
This is a replay running against p2p/chain.persistBlocks() where
the data were captured from.
* prepare stubs for PoA engine
* split executor source into sup-modules
why:
make room for updates, clique integration should go into
executor/update_poastate.nim
* Simplify p2p/executor.processBlock() function prototype
why:
vmState argument always wraps basicChainDB
* split processBlock() into sub-functions
why:
isolate the part where it will support clique/poa
* provided additional processTransaction() function prototype without _fork_ argument
why:
with the exception of some tests, the _fork_ argument is always derived
from the other prototype argument _vmState_
details:
similar situation with makeReceipt()
* provide new processBlock() version explicitly supporting PoA
details:
The new processBlock() version supporting PoA is the general one also
supporting non-PoA networks, it needs an additional _Clique_ descriptor
function argument for PoA state (if any.)
The old processBlock() function without the _Clique_ descriptor argument
retorns an error on PoA networgs (e.g. Goerli.)
* re-implemented Clique descriptor as _ref object_
why:
gives more flexibility when moving around the descriptor object
details:
also cleaned up a bit the clique sources
* comments for clarifying handling of Clique/PoA state descriptor
usually, there is always a sender around `getRecipient` call.
no need to recalculate sender. and more important, in some of
JSON-RPC/GraphQL call, the sender is come from `rpcCallData`,
not from `tx.getSender`. or in ohter situation when the tx is
an unsigned tx, without `r,s,v` fields to calculate sender.
instead of using header as input param, now getReceipts using
receiptRoot hash, the intention is clearer and less data passed around
when we only using receiptRoot instead of whole block header.
