* Explicitly use shared `Kvt` table on `Ledger` and `Clique` lookup.
why:
Speeds up lookup time with `Aristo` backend. For writing `Clique` data,
the `Companion` model allows to write `Clique` data past the database
locked by evm transactions.
* Implement `CoreDb` profiling with API tracking
why:
Chasing time spent per APT procs ...
* Implement `Ledger` profiling with API tracking
why:
Chasing time spent per APT procs ...
* Always hashify when commiting or storing
why:
A dirty cache makes no sense when committing
* Make sure that a zero key is created when adding/updating vertices
why:
This is an error fix mainly for edge cases. A typical error was
that the root key got deleted when there were only a few vertices
left on the DB.
* Need all created and changed vertices zero-keyed on the cache
why:
A zero key (i.e. empty Merkle hash) indicates that a vertex key
needs to be updated. This would not be needed immediately after
a merge as there is an actual leaf path on the cache layer. But
after subsequent merge and delete operations this information
might get blurred.
* Re-org hashing algorithm
why:
Apart from errors, the previous implementation was too slow for
two reasons:
+ some control hashes were calculated for debugging (now all
verification is done in `aristo_check` module)
+ the leaf paths stored on the cache are used to build the
labelling (aka hashing) schedule; there paths were accumulated
over successive hash sessions although it is clear that all
keys were generated, already
* 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)
* 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
