Fix dboptions init (#2391)
For the block cache to be shared between column families, the options
instance must be shared between the various column families being
created. This also ensures that there is only one source of truth for
configuration options instead of having two different sets depending on
how the tables were initialized.

This PR also removes the re-opening mechanism which can double startup
time - every time the database is opened, the log is replayed - a large
log file will take a long time to open.

Finally, several options got correclty implemented as column family
options, including an one that puts a hash index in the SST files.

Aristo uses pre classified tree types cont1 (#2389)
* Provide dedicated functions for deleteing accounts and storage trees

why:
  Storage trees are always linked to an account, so there is no need
  for an application to fiddle about (e.g. re-cycling, unlinking)
  storage tree vertex IDs.

* Remove `delete()` and other cruft from API, `aristo_delete`, etc.

* clean up delete functions

details:
  The delete implementations `deleteImpl()` and `delTreeImpl()` do not
  need to be super generic anymore as all the edge cases are covered by
  the specialised `deleteAccountPayload()`, `deleteGenericData()`, etc.

* Avoid unnecessary re-calculations of account keys

why:
  The function `registerAccountForUpdate()` did extract the storage ID
  (if any) and automatically marked the Merkle keys along the account
  path for re-hashing.

  This would also apply if there was later detected that the account
  or the storage tree did not need to be updated.

  So the `registerAccountForUpdate()` function was split into a part
  which retrieved the storage ID, and another one which marked the
  Merkle keys for re-calculation to be applied only when needed.

Aristo uses pre classified tree types (#2385)
* Remove unused `merge*()` functions (for production)

details:
  Some functionality moved to test suite

* Make sure that only `AccountData` leaf type is exactly used on VertexID(1)

* clean up payload type

* Provide dedicated functions for merging accounts and storage trees

why:
  Storage trees are always linked to an account, so there is no need
  for an application to fiddle about (e.e. creating, re-cycling) with
  storage tree vertex IDs.

* CoreDb: Disable tracer functionality

why:
  Must be updated to accommodate new/changed `Aristo` functions.

* CoreDb: Use new `mergeXXX()` functions

why:
  Makes explicit vertex ID management obsolete for creating new
  storage trees.

* Remove `mergePayload()` and other cruft from API, `aristo_merge`, etc.

* clean up merge functions

details:
  The merge implementation `mergePayloadImpl()` does not need to be super
  generic anymore as all the edge cases are covered by the specialised
  functions `mergeAccountPayload()`, `mergeGenericData()`, and
  `mergeStorageData()`.

* No tracer available at the moment, so disable offending tests

avoid computing state root just to know if storage is empty (#2380)
The state root computation here is one of the major hotspots in block
processing - in the cases the code only needs to know if it's empty or
not, it can be done a lot faster.

Adding a separate function for this looks fragile and should probably be
revisited.

Light verification and storage mode for import (#2367)
When performing block import, we can batch state root verifications and
header checks, doing them only once per chunk of blocks, assuming that
the other blocks in the batch are valid by extension.

When we're not generating receipts, we can also skip per-transaction
state root computation pre-byzantium, which is what provides a ~20%
speedup in this PR, at least on those early blocks :)

We also stop storing transactions, receipts and uncles redundantly when
importing from era1 - there is no need to waste database storage on this
when we can load it from the era1 file (eventually).

Coeredb related clean up and maint fixes (#2360)
* Fix initialiser

why:
  Possible crash (app profiling, tracer etc.)

* Update column family options processing

why:
  Same for kvt as for aristo

* Move `AristoDbDualRocks` backend type to the test suite

why:
  So it is not available for production

* Fix typos in API jump table

why:
  Used for tracing and app profiling only. Needed some update

* Purged CoreDb legacy API

why:
  Not needed anymore, was transitionary and disabled.

* Rename `flush` argument to `eradicate` in a DB close context

why:
  The word `eradicate` leaves no doubt what is meant

* Rename `stoFlush()` -> `stoDelete()`

* Rename `core_apps_newapi` -> `core_apps` (not so new anymore)

Avoid recomputing hashes when persisting data (#2350) 2024-06-14 07:10:00 +02:00
Jordan Hrycaj 5a5cc6295e
Triggered write event for kvt (#2351)
* bump rockdb

* Rename `KVT` objects related to filters according to `Aristo` naming

details:
  filter* => delta*
  roFilter => balancer

* Compulsory error handling if `persistent()` fails

* Add return code to `reCentre()`

why:
  Might eventually fail if re-centring is blocked. Some logic will be
  added in subsequent patch sets.

* Add column families from earlier session to rocksdb in opening procedure

why:
  All previously used CFs must be declared when re-opening an existing
  database.

* Update `init()` and add rocksdb `reinit()` methods for changing parameters

why:
  Opening a set column families (with different open options) must span
  at least the ones that are already on disk.

* Provide write-trigger-event interface into `Aristo` backend

why:
  This allows to save data from a guest application (think `KVT`) to
  get synced with the write cycle so the guest and `Aristo` save all
  atomically.

* Use `KVT` with new column family interface from `Aristo`

* Remove obsolete guest interface

* Implement `KVT` piggyback on `Aristo` backend

* CoreDb: Add separate `KVT`/`Aristo` backend mode for debugging

* Remove `rocks_db` import from `persist()` function

why:
  Some systems (i.p `fluffy` and friends) use the `Aristo` memory
  backend emulation and do not link against rocksdb when building the
  application. So this should fix that problem.

Apply some basic rocksdb options (#2339)
These options, inspired by Nethermind and general internet wisdom, bring
the database size down to 2/3 without affecting throughput. In theory,
they should also bring down memory usage and/or make more efficient use
of whatever memory is already assigned to rocksdb but this needs
verification in a longer test at synced-mainnet sizes.

In the meantime, they make testing easier by removing some noise that
the profiler says are bad, such as excessive SkipList access (countered
by bloom filters).

avoid initTable (#2328)
`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.

Consolidate block type for block processing (#2325)
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)

use statically linked rocksdb on linux/mac, dll on windows (#2291)
The `rocksdb` version shipped with distributions is typically old and
therefore often lacks features we use - it also doesn't match the one
assumed by nim-rocksdb leading to ABI mismatch risks.

Instead of depending on the system rocksdb, we'll now use the rocksdb
version assumed by nim-rocksdb and locked in its vendor folder by always
building it together with nimbus.

This avoids the problem of unknown rocksdb versions at a (small) cost to
build time.

CI caching and full windows support for building from source [remains

* Remove all journal related stuff

* Refactor function names journal*() => delta*(), filter*() => delta*()

* remove `trg` fileld from `FilterRef`

why:
  Same as `kMap[$1]`

* Re-type FilterRef.src as `HashKey`

why:
  So it is directly comparable to `kMap[$1]`

* Moved `vGen[]` field from `LayerFinalRef` to `LayerDeltaRef`

why:
  Then a separate `FilterRef` type is not needed, anymore

* Rename `roFilter` field in `AristoDbRef` => `balancer`

why:
  New name more appropriate.

* Replace `FilterRef` by `LayerDeltaRef` type

why:
  This allows to avoid copying into the `balancer` (see next patch set)
  most of the time. Typically, only one instance is running on the backend
  and the `balancer` is only used as a stage before saving data.

* Refactor way how to store data persistently

why:
  Avoid useless copy when staging `top` layer for persistently saving to
  backend.

Speed up account ledger a little (#2279)
`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.

Aristo avoid storage trie update race conditions (#2251)
* Update TDD suite logger output format choices

why:
  New format is not practical for TDD as it just dumps data across a wide
  range (considerably larder than 80 columns.)

  So the new format can be turned on by function argument.

* Update unit tests samples configuration

why:
  Slightly changed the way to find the `era1` directory

* Remove compiler warnings (fix deprecated expressions and phrases)

* Update `Aristo` debugging tools

* Always update the `storageID` field of account leaf vertices

why:
  Storage tries are weekly linked to an account leaf object in that
  the `storageID` field is updated by the application.

  Previously, `Aristo` verified that leaf objects make sense when passed
  to the database. As a consequence
  * the database was inconsistent for a short while
  * the burden for correctness was all on the application which led
    to delayed error handling which is hard to debug.

  So `Aristo` will internally update the account leaf objects so that
  there are no race conditions due to the storage trie handling

* Aristo: Let `stow()`/`persist()` bail out unless there is a `VertexID(1)`

why:
  The journal and filter logic depends on the hash of the `VertexID(1)`
  which is commonly known as the state root. This implies that all
  changes to the database are somehow related to that.

* Make sure that a `Ledger` account does not overwrite the storage trie reference

why:
  Due to the abstraction of a sub-trie (now referred to as column with a
  hash describing its state) there was a weakness in the `Aristo` handler
  where an account leaf could be overwritten though changing the validity
  of the database. This has been changed and the database will now reject
  such changes.

  This patch fixes the behaviour on the application layer. In particular,
  the column handle returned by the `CoreDb` needs to be updated by
  the `Aristo` database state. This mitigates the problem that a storage
  trie might have vanished or re-apperaed with a different vertex ID.

* Fix sub-trie deletion test

why:
  Was originally hinged on `VertexID(1)` which cannot be wholesale
  deleted anymore after the last Aristo update. Also, running with
  `VertexID(2)` needs an artificial `VertexID(1)` for making `stow()`
  or `persist()` work.

* Cosmetics

* Activate `test_generalstate_json`

* Temporarily `deactivate test_tracer_json`

* Fix copyright header

Kvt remodel tx and forked descriptors (#2168)
* Aristo: Generalise alien/guest interface for piggiback on database

* Aristo: Code cosmetics

* CoreDb+Kvt: Update transaction API

why:
  Use single addressable function `forkTx(backLevel: int)` as used
  in `Aristo`. So `Kvt` can be synced simultaneously to `Aristo`.

also:
  Refactored `kvt_tx.nim` in a similar fashion to `Aristo`.

* Kvt: Replace `LayerDelta` object by reference

why:
  Will be needed when introducing filters

* Kvt: Remodel backend filter facility similar to `Aristo`

why:
  This allows to operate on several KVT instances simultaneously.

* CoreDb+Kvt: Fix on-disk storage

why:
  Overlooked name change: `stow()` => `persist()` for permanent storage

* Fix copyright headers

Core db+aristo fixes and tx handling updates (#2164)
* Aristo: Rename journal related sources and functions

why:
  Previously, the naming was hinged on the phrases `fifo`, `filter` etc.
  which reflect the inner workings of cascaded filters. This was
  unfortunate for reading/understanding the source code for actions where
  the focus is the journal as a whole.

* Aristo: Fix buffer overflow (path length truncating error)

* Aristo: Tighten `hikeUp()` stop check, update error code

why:
  Detect dangling vertex links. These are legit with `snap` sync
  processing but not with regular processing.

* Aristo: Raise assert in regular mode `merge()` at a dangling link/edge

why:
  With `snap` sync processing, partial trees are ok and can be amended.
  Not so in regular mode.

  Previously there was only a debug message when a non-legit dangling edge
  was encountered.

* Aristo: Make sure that vertices are copied before modification

why:
  Otherwise vertices from lower layers might also be modified

* Aristo: Fix relaxed mode for validity checker `check()`

* Remove cruft

* Aristo: Update API for transaction handling

details:
+ Split `aristo_tx.nim` into sub-modules
+ Split `forkWith()` into `findTx()` + `forkTx()`
+ Removed `forkTop()`, `forkBase()` (now superseded by new `forkTx()`)

Core db+aristo update recovery journal management (#2156)
* Aristo: Allow to define/set `FilterID` for journal filter records

why:
  After some changes, the `FilterID` is isomorphic to the `BlockNumber`
  scalar (well, the first 2^64 entries of a `BlockNumber`.)

  The needed change for `FilterID` is that the `FilterID(0)` value is
  valid part of the `FilterID` scalar. A non-valid `FilterID` entry is
  represented by `none(FilterID)`.

* Aristo: Split off function `persist()` as persistent version of `stow()`

why:
  In production, `stow(persistent=false,..)` is currently unused. So,
  using `persist()` rather than `stow(persistent=true,..)` improves
  readability and is better to maintain.

* CoreDb+Aristo: Store block numbers in journal records

why:
  This makes journal records searchable by block numbers

* Aristo: Rename some journal related functions

why:
  The name *journal* is more appropriate to api functions than something
   with *fifo* or *filter*.

* CoreDb+Aristo: Update last/oldest journal state retrieval

* CoreDb+Aristo: Register block number with state root in journal

why:
  No need anymore for extra lookup table `stRootToBlockNum` which maps
  a storage root -> block number.

* Aristo: Remove unused function `getFilUbe()` from api

* CoreDb: Remove now unused virtual table `stRootToBlockNum`

why:
  Was used to map a state root to a block number. This functionality
  is now embedded into the recovery journal backend.

* Turn of API tracking (will fail on `fluffy`)

Update aristo journal functionality (#2155)
* Aristo: Code cosmetics, e.g. update some CamelCase names

* CoreDb+Aristo: Provide oldest known state root implied

details:
  The Aristo journal allows to recover earlier but not all state roots.

* Aristo: Fix journal backward index operator, e.g. `[^1]`

* Aristo: Fix journal updater

why:
  The `fifosStore()` store function slightly misinterpreted the update
  instructions when translation is to database `put()` functions. The
  effect was that the journal was ever growing due to stale entries which
  were never deleted.

* CoreDb+Aristo: Provide utils for purging stale data from the KVT

details:
  See earlier patch, not all state roots are available. This patch
  provides a mapping from some state root to a block number and allows to
  remove all KVT data related to a particular block number

* Aristo+Kvt: Implement a clean up schedule for expired data in KVT

why:
  For a single state ledger like `Aristo`, there is only a limited
  backlog of states. So KVT data (i.e. headers etc.) are cleaned up
  regularly

why:

* Aristo: Renamed journal `stats()` to `capacity()`

why:
  `Stats()` was a misnomer

* Aristo: Provide backend read caches for key and vertex IDs

* 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)

why:

  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

why:
  Avoiding to run two DBMS systems in parallel.

details:
  This patch makes sure that before creating a new `BaseVMState` the

  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.

Core db implement ctx layer for mpt state admin (#2082)
* 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

* Kvt: Simplify DB clone/peers management

* Aristo: Simplify DB clone/peers management

* Aristo: Adjust unit test for working with memory DB only

why:

* CoredDb+Kvt: Simplify API for KVT

why:
  Simplified storage models (was over engineered) for better performance
  and code maintenance.

* CoredDb+Aristo: Simplify API for `Aristo`

why:

  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

Coredb use stackable api for aristo backend (#2060)
* Aristo/Kvt: Provide function hooks APIs

why:
  These APIs can be used for installing tracers, profiling functoinality,
  and other niceties on the databases.

* Aristo: Provide optional API profiling

details:
  It basically is a re-implementation of the `CoreDb` profiling
  implementation

* Kvt: Provide optional API profiling similar to `Aristo`

* CoreDb: Re-implementing profiling using `aristo_profile`

* Ledger: Re-implementing profiling using `aristo_profile`

* CoreDb: Update unit tests for maintainability

* update copyright dates

Provide public default db symbol (#2050)
* CoreDb: Provide default db backend symbols

why:
  Handy for running `Aristo` against standard tests

note:
  These defaults are currently set to legacy DB types. The must be
  enabled manually in `db/core_db.nim`.

* Provide `Aristo` for macro assembler related tests

caveat:
  Some tests use `initStorageTrie()` which lets `Aristo` bail out. The
  test need to run on `distinct_ledgers` (or something like) rather than
  `distinct_tries`.

* Tests: Misc modules that can run on `Aristo` as well

* NoHive: Module that can run on `Aristo` as well

* Fix copyright year

Aristodb remove obsolete and time consuming admin features (#2048)
* Aristo: Reorg `hashify()` using different schedule algorithm

why:
  Directly calculating the search tree top down from the roots turns
  out to be faster than using the cached structures left over by `merge()`
  and `delete()`.
  Time gains is short of 20%

* Aristo: Remove `lTab[]` leaf entry object type

why:
  Not used anymore. It was previously needed to build the schedule for
  `hashify()`.

* Aristo: Avoid unnecessary re-org of the vertex ID recycling list

why:
  This list can become quite large so a heuristic is employed whether
  it makes sense to re-org.

  Also, re-org check is only done by `delete()` functions.

* Aristo: Remove key/reverse lookup table from tx layers

why:
  It is ignored except for handling proof nodes and costs unnecessary
  run time resources.

  This feature was originally needed to accommodate the mental transition
  from the legacy MPT to the `Aristo` trie :).

Aristo db remove over engineered object type (#2027)
* CoreDb: update test suite

* Aristo: Simplify reverse key map

why:
  The reverse key map `pAmk: (root,key) -> {vid,..}` as been simplified to
  `pAmk: key -> {vid,..}` as the state `root` domain argument is not used,
  anymore

* Aristo: Remove `HashLabel` object type and replace it by `HashKey`

why:
  The `HashLabel` object attaches a root hash to a hash key. This is
  nowhere used, anymore.

* Fix copyright

Core db+friends fix sync bail outs (#2026)
* Aristo: Update schedule runner for `hashify()`

why:
  Width-first schedule walker overlooked resolvable vertex and ended in
  a deadlock situation

* CoreDb+Aristo: Update error code for fringe condition

* Ledger: Remove redundant extra MPT hashing statements

why:
  These statement were used for troubleshooting

* CoreDb: Couch medicine for legacy DB backend

why:
  MPT will occasionally enter inconsistent states after deletion, some
  dirty fix is randomly added to mitgate that.
