* Error return in `persistBlocks()` on initial `VmState` roblem
why:
previously threw an exception
* Updated sync mode option
why:
using enum rather than bool => space for more
* Added sync mode `full`, re-factued legacy sync
also:
rebased
* Fix typo (crashes `pesistBlocks()` otherwise)
also:
rebase to master
* Reduce log ticker noise by suppressing duplicate messages
* Clarify staged queue overflow handling
why:
backtrack/re-org mode in `stageItem()` should be detected by both,
the global indicator or the work item where it might have moved into.
also:
rebased
* Added sepolia specs
* temporarily avoid latest `master` branch from `nim-eth1`
why:
Currently does not cleanly compile after the `bearssl` split api update.
* Relocated `IntervalSets` to nim-stew repo
* Accumulate accounts on temporary kv-DB
why:
Explore the data as returned from snap/1. Will be converted to a
`eth/db` next.
details:
Verify and accumulate per/state-root accounts downloaded via snap.
also:
Some unit tests
* Replace `Table` by `TrieDatabaseRef` for accounts accumulator
* update ticker statistics
details:
mean/variance based counter update
* allow persistent db for proved accounts
* rebase, and globally activate unit test
* fix statistics
* Using `IntervalSet` type data for `LeafRange`
* Updated log ticker
* Update to `eth67`
details:
Disabled by default, use `ENABLE_LEGACY_ETH66=0` to enable
No support for `Get/NodeData` dialogue via eth, anymore
* Dissolved fetch/common.nim
details;
the log/ticker part becomes ticker.nim
the interval range management is merged into fetch.nim
* Updated account scheduler
why:
The previous scheduler fetched each account once (for different state
roots.) The updated scheduler re-calibrates after a change of the state
root and potentially (until told otherwise) fetches all possible
accounts.
* Fix `high(P)` fringe cases in `IntervalSet` handling
why:
The `high(P)` value for a point type `P` cannot be represented with
half open intervals `[a,b)` for a,b points of `P`. So this single value
needs extra treatment which was slightly wrong.
* Updated docu/comments
also:
rebased
* Update scheduler
details:
Change the `pivot` management when creating new accounts lists. It is
strictly increasing (and wrapping around) depending on last updated
accounts list.
* Fix/recover download flag
why:
The fetch indicator used to control the data download somehow got
lost during re-org.
* Updated chronicles/logger topics
* Reorganised run state flags
why:
The original code used a pair of boolean flags `(stopped,stopThisState)`
which was translated to three states running, stoppedPending, and
stopped. It is currently not clear whether collapsing some states was
correct. So the original logic has been re-stored, albeit wrapped into
directives like `isStopped()` etc.
also:
Moving some function bodies in `worker.nim`
* Moved `reply_data.nim` and `validate_trienode.nim` to sub-directory `fetch_trie`
why:
Only used in `fetch_trie.nim`.
* Move `fetch_*` file and directory objects to `fetch` subdirectory
why:
Only used in `fetch.nim`
* Added start/stop and/or setup/release methods for all sub-modules
why:
good housekeeping
also:
updated getters/setters for ctrl states
updated trace messages
if we are not voting, coinbase should be filled with zero
because other subsystem e.g txpool can produce block header
with non zero coinbase. if that coinbase is one of the signer
and the nonce is zero, that signer will be vote out from
signer list
* Disentangle `collect` module from `reply_data`
why:
Now the module visible from `collect` for fetching data is `peer/fetch`
only.
* Merge `SnapPeerHunt` into `collect`
why:
This part needs to be known by `collect`, only
* rename collect => worker
* Dissolve `sync_fetch_xdesc` module into `common`
why:
Descriptor is only used in `common` and `fetch_trie`
* rename `snap/peer` directory => `snap/worker`
* rename `SnapSync` -> `Worker`, `SnapPeer` -> `WorkerBuddy`
* moved `snap/base_desc.nim` -> `snap/worker/worker_desc.nim`
* Unified opaque object ref naming in `worker_desc.nim`
details:
indicated my inheriting module (exactly one, always)
* Reorg SnapPeerBase descriptor, notably start/stop flags
details:
Instead of using three boolean flags startedFetch, stopped, and
stopThisState a single enum type is used with values SyncRunningOk,
SyncStopRequest, and SyncStopped.
* Restricting snap to eth66 and later
why:
Id-tracked request/response wire protocol can handle overlapped
responses when requests are sent in row.
* Align function names with source code file names
why:
Easier to reconcile when following the implemented logic.
* Update trace logging (want file locations)
why:
The macros previously used hid the relevant file location (when
`chroniclesLineNumbers` turned on.) It rather printed the file
location of the template that was wrapping `trace`.
* Use KeyedQueue table instead of sequence
why:
Quick access, easy configuration as LRU or FIFO with max entries
(currently LRU.)
* Dissolve `SnapPeerEx` object extension into `SnapPeer`
why;
It is logically cleaner and more obvious not to inherit from
`SnapPeerBase` but to specify opaque field object references of the
merged `SnapPeer` object. These can then be locally inherited.
* Dissolve `SnapSyncEx` object extension into `SnapSync`
why;
It is logically cleaner and more obvious not to inherit from
`SnapSyncEx` but to specify opaque field object references of
the `SnapPeer` object. These can then be locally inherited.
Also, in the re-factored code here the interface descriptor
`SnapSyncCtx` inherited `SnapSyncEx` which was sub-optimal (OO
inheritance makes it easier to work with call back functions.)
* new: time_helper, types
* new: path_desc
* new: base_desc
* Re-organised objects inheritance
why:
Previous code used macros to instantiate opaque object references. This
has been re-implemented with OO inheritance based logic.
* Normalised trace macros
* Using distinct types for Hash256 aliases
why:
Better control of the meaning of the hashes, all or the same format
caveat:
The protocol handler DSL used by eth66.nim and snap1.nim uses the
underlying type Hash256 and cannot handle the distinct alias in
rlp and chronicles/log macros. So Hash256 is used directly (does
not change readability as the type is clear by parameter names.)
* Use type name eth and snap (rather than snap1)
* Prettified snap/eth handler trace messages
* Regrouped sync sources
details:
Snap storage related sources are moved to common directory.
Option --new-sync renamed to --snap-sync
also:
Normalised logging for secondary/non-protocol handlers.
* Merge protocol wrapper files => protocol.nim
details:
Merge wrapper sync/protocol_ethxx.nim and sync/protocol_snapxx.nim
into single file snap/protocol.nim
* Comments cosmetics
* Similar start logic for blockchain_sync.nim and sync/snap.nim
* Renamed p2p/blockchain_sync.nim -> sync/fast.nim
why:
Accidentally wrapped into waitFor() directive with reviving jl/sync
branch.
also:
Decorate eth/66 and snap/1 protocol trace messages with protocol
type and version
* Squashed snap-sync-preview patch
why:
Providing end results makes it easier to have an overview.
Collected patch set comments are available as nimbus/sync/ChangeLog.md
in chronological order, oldest first.
* Removed some cruft and obsolete imports, normalised logging
* Update exception tracinig
* Use lazy JSON parser
why:
Uint246 type is not directly supported by the JSON serializer
* Json parser update for stringified UInt256 integers
why:
Now available
* update sub-module branch reference
- remove `waitFor` and store async result in Future[T] for future execution
instead of blocking other services from starting and running.
This also fixes very long delay Ctrl-C issue. Fixes#585
- always create sealing engine instance even though there is no
signer. other services such engine api need it.
if engine api receive forkChoiceUpdated and turn out
reorg happened, sealing engine must update txpool
head.
so in the next iteration when the txpool asked to
produce a fresh block, it will produce it in the
current 'correct' chain and abandon side chain.
