* Code cosmetics
* Aristo+Kvt: Fix api wrappers
why:
Api setup killed the backend descriptor when backend mapping was
disabled.
* Aristo: Implement masked profiling entries
why:
Database backend should be listed but not counted in tally
* CoreDb: Simplify backend() methods
why:
DBMS backend access Was provided very early and over engineered. Now
there are only two backend machines, one for `Kvt` and the other one
for an `Mpt` available only via new API.
* CoreDb: Code cleanup regarding descriptor types
* CoreDb: Refactor/redefine `persistent()` methods
why:
There were `persistent()` methods for any type of caching storage
facilities `Kvt`, `Mpt`, `Phk`, and `Acc`. Now there is only a single
`persistent()` method storing all facilities in tandem (similar to
how transactions work.)
For non shared `Kvt` tables, there is now an extra storage method
`saveOffSite()`.
* CoreDb lingo update: `trie` becomes `column`
why:
Notion of a `trie` is pretty much hidden by the new `CoreDb` api.
Revealed are sort of database columns for accounts an storage data,
any of which have an internal state represented by a Keccack hash.
So a `trie` or `MPT` becomes a `column` and a `rootHash` becomes a
column state.
* Aristo: rename backend filed `filters` => `journal`
* Update full sync logging
details:
+ Disable eth handler noise while syncing
+ Log journal depth (if available)
* Fix copyright year
* Fix cruft and unwanted imports
* Update README
* Nimbus-main: replaced `PruneMode` options by `ChainDbMode` options
details:
For the legacy database, this changes the phrase
- `conf.pruneMode == PruneMode.Full` to the expression
+ `conf.chainDbMode == ChainDbMode.Prune`.
* Fix issues moaned about by NIM compiler
* Fix copyright year
* Aristo+RocksDB: Update backend drivers
why:
RocksDB update allows use some of the newly provided methods which
were previously implemented by using the very C backend (for the lack
of NIM methods.)
* Aristo+RocksDB: Simplify drivers wrapper
* Kvt: Update backend drivers and wrappers similar to `Aristo`
* Aristo+Kvm: Use column families for RocksDB
* Aristo+MemoryDB: Code cosmetics
* Aristo: Provide guest column family for export
why:
So `Kvt` can piggyback on `Aristo` so there avoiding to run a second
DBMS system in parallel.
* Kvt: Provide import mechanism for RoksDB guest column family
why:
So `Kvt` can piggyback on `Aristo` so there avoiding to run a second
DBMS system in parallel.
* CoreDb+Aristo: Run persistent `Kvt` DB piggybacked on `Aristo`
why:
Avoiding to run two DBMS systems in parallel.
* Fix copyright year
* Ditto
* 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
* Kvt: Update API hooks
* Aristo: Generalised merging snap proofs, now for multiple state roots
why:
This accommodates pre-loading partial tries for unit tests
* Aristo: Update some unit tests
* CoreDb+Aristo: Re-factor tracer
why:
Was bonkers anyway. The main change is that the trace journal is now
kept in a way similar to a transaction layer so that it can predictably
interact with DB transactions.
* Ledger: Debugging helper
* Update tracer unit test applicable for `Aristo`
* Fix copyright year
* Disable `dump()` function as compile time default
why:
This needs to pull in the `rocks_db` library at compile time.
* Static link rocksdb into Nimbus.
* Link in additional compression libraries.
* Support static linking for MacOS.
* Add flag to support disabling rocksdb static linking.
* Static linking is disabled by default. Build nimbus with static linking using: make nimbus_rocksdb_static
* Update nim-rocksdb to latest.
* 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.
- The fluffy test vector repo got forked (well, copied rather) to
become the official one under ethereum github org, so we change
to that repo now and archive ours.
- Our repo also stored accumulator / historical_roots, replace
that with a new repo which is only for network configs.
- Several changes needed to be made due to test vectors that got
updated + some of them got changed to / are yaml format instead of
json.
* 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
* CoreDb+Aristo: Fix handler code
* Aristo+Kvt: Remove cruft
* Aristo+Kvt: The function `forkTop()` always provides a single transaction
why:
Previously it provided a single squashed tx only if there were any. Now
it will provide a blind one if there were none.
* Fix Copyright header
* Fix 'value out of range' RangeDefect caused by large/expensive blocks/transactions during DOS period.
* Clear witness cache in AccountCache persist.
* Revert previous fix and force clear cache after processing each block.
* Revert clear cache in process block.
* CoreDb+Ledger: Update logging
why:
Use symbol `api` rather than `ctx` because the latter will be used
as name for particular objects
* CoreDb: Remove cruft
* CoreDb: Remove `TxID` support
why:
It is nowhere used and ugly implemented. The upcoming context layer
will be a cleaner alternative to use, instead should this particular
functionality be needed.
* CoreDb: Rearrange base methods in source code for better reading
* CoreDb+Aristo: Update API closures for better reading & maintenance
* CoreDb: Implement context layer for MPT
why:
On `Aristo` the context layer allows to manage different views on
the same backend database. This is an abstraction of the legacy
hexary trie which can be localised on a particular root nose.
details:
The `ctx` context provides the state (equiv. to state root) of the
database for MPT and account descriptors.
