* 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)
This is a workaround following hive example, because one of the test case
withdrawalsAmountBounds.json, have bad blocks between good blocks.
And that bad blocks contains big int too big to fit in uint64 of
withdrawal amount field.
Clients who still importing concatenated blocks cannot pass all tests.
this is a preparation for migration to confutils based config
although there is still some getConfiguration usage in tests code
it will be removed after new config arrived
* Re-adjust canonical head to parent of block to be inserted
why:
of the failing tests that remain to be solved, 30 of those will succeed
if the canonical database chain head is cleverly adjusted -- yes, it
looks like a hack, indeed.
details:
at the moment, this hack works for the non-hive tests only and is
triggered by a boolean argument passed on to the chain.persistBlocks()
method.
* Use parent instead of canonical head for block to be inserted
why:
side chains need to be inserted typically somewhere before the
canonical head.
details:
the previous _hack_ was unnecessary and removed, it was inspired by
some verification in persistBlocks() which explicitly referenced the
canonical head (which now might or might not refer to the newly inserted
header.)
* remove unnecessary code + comment
now we have hive simulators written in nim:
- ethereum/consensus
- ethereum/graphql
Using these simulators, we can debug test cases without have to run
hive or docker.
