`initTable` is obsolete since nim 0.19 and can introduce significant
memory overhead while providing no benefit (since the table will be
grown to the default initial size on first use anyway).
In particular, aristo layers will not necessarily use all tables they
initialize, for exampe when many empty accounts are being created.
This PR consolidates the split header-body sequences into a single EthBlock
sequence and cleans up the fallout from that which significantly reduces
block processing overhead during import thanks to less garbage collection
and fewer copies of things all around.
Notably, since the number of headers must always match the number of bodies,
we also get rid of a pointless degree of freedom that in the future could
introduce unnecessary bugs.
* only read header and body from era file
* avoid several unnecessary copies along the block processing way
* simplify signatures, cleaning up unused arguemnts and returns
* use `stew/assign2` in a few strategic places where the generated
nim assignent is slow and add a few `move` to work around poor
analysis in nim 1.6 (will need to be revisited for 2.0)

* Cleanup unneeded stateless and block witness code. Keeping MultiKeys which is used in the eth_getProofsByBlockNumber RPC endpoint which is needed for the Fluffy state network bridge.
* Rename generateWitness flag to collectWitnessData to better describe what the flag does. We only collect the keys of the touched accounts and storage slots but no block witness generation is supported for now.
* Move remaining stateless code into nimbus directory.
* Add vmstate parameter to ChainRef to fix test.
* Exclude *.in from check copyright year

`persist` is a hotspot when processing blocks because it is run at least
once per transaction and loops over the entire account cache every time.
Here, we introduce an extra `dirty` map that keeps track of all accounts
that need checking during `persist` which fixes the immediate
inefficiency, though probably this could benefit from a more thorough
review - we also get rid of the unused clearCache flag - we start with
a fresh cache on every fresh vmState.
* avoid unnecessary code hash comparisons
* avoid unnecessary copies when iterating
* use EMPTY_CODE_HASH throughout for code hash comparison
* Attempt to roll back stateless mode implementation in a single PR
why:
+ Stateless mode is not fully working and in the way
+ Single PR should make it feasible to investigate for a possible
re-implementation
* Fix copyright year
* Fix annotation for exception (evmc mode)
* Suspend `snap` sync tests
why:
Snap needs to be updated. While this is not done, tests are obsolete
and eat up memory resources only
* Suspend rocks DB timing tests
why:
Currently of no use for general test suite.
* Mothballed unused evm code for opportunistic DB handling
why:
Needs to be refactored anyway. Uses hard coded protocol dependencies.
* Update `eth` protocol configuration
why:
+ new upcoming version `eth68`
+ prepare for eth-multi protocol stack support
* Strip the `legacy_` prefix from eth66 compiler flag variable
why:
Being it is an oddity having `eth67_enabled`, `eth68_enabled`, and
`legacy_eth_66_enabled`.
* Providing eth68 stubs
* Fix copyright year
* Fix eth68 stub method name
* 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
* 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.
* Fix issue causing vmflags to be reset during call to processBlocks and enable witness generation in test_blockchain_json test.
* Fix copyright notice on updated files.
Both types are not safe and require validation/conversion
from rpc implementer.
This PR change it to safer types and delegate the conversion
and validation to the rpc library.
* 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)
* Using different `tmp` directories for `Kvt` and `Aristo`
why:
Closing one database would leave the other set of directories
incomplete.
* Code cosmetics, silence compiler
* Fix typo `EMPTY_ROOT_HASH` vs. `EMPTY_CODE_HASH`
* Fix copyright years
* Make sure that storage tries are not pruned (by default) on the new Ledger API
why:
Pruning might kill some unwanted entries from storage tries ending up with an unstable database
leading to crashes.
* Implement `CoreDb` and `LedgerRef` API tracing
details:
+ Locally enabled at compile time via constants `ProvideCoreDbLegacyAPI`
and `EnableApiTracking` in either `base.nim` source
+ If enabled it can be selectively turned on/off via public switches in
the `CoreDb` descriptor.
* Allow suppressing opportunistic `ifNecessaryGetXxx()` functions
why:
Better troubleshooting when the system crashes (assertions will then
most probably happen outside an `async` function.)
* 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.
