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).
* Cleanup unneeded stateless and block witness code. Keeping MultiKeys which is used in the eth_getProofsByBlockNumber RPC endpoint which is needed for the Fluffy state network bridge.
* Rename generateWitness flag to collectWitnessData to better describe what the flag does. We only collect the keys of the touched accounts and storage slots but no block witness generation is supported for now.
* Move remaining stateless code into nimbus directory.
* Add vmstate parameter to ChainRef to fix test.
* Exclude *.in from check copyright year

This new option saves a CSV to disk while performing `import` such that
the performance of one import can be compared with the other.
This early version is likely to change in the future
These options are there mainly to drive experiments, and are therefore
hidden.
One thing that this PR brings in is an initial set of caches and buffers for rocksdb - the set that I've been using during various performance tests to get to a viable baseline performance level.
This PR extends the `nimbus import` command to also allow reading from
era files - this command allows creating or topping up an existing
database with data coming from era files instead of network sync.
* add `--era1-dir` and `--max-blocks` options to command line
* make `persistBlocks` report basic stats like transactions and gas
* improve error reporting in several API
* allow importing multiple RLP files in one go
* clean up logging options to match nimbus-eth2
* make sure database is closed properly on shutdown
* Attempt to roll back stateless mode implementation in a single PR
why:
+ Stateless mode is not fully working and in the way
+ Single PR should make it feasible to investigate for a possible
re-implementation
* Fix copyright year
* Fix annotation for exception (evmc mode)
* 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
* Added procs to get and store block witness in db and add generate-witness cli flag.
* Completed initial implementation of block witness storage.
* Added test to verify witness is persisted to db after call to persistBlock.
* Update getBlockWitness to return witness using Result type.
* Make generate witness parameter hidden.
* Nimbus light client integration with status-go
* Add cleanup code, address review comments
* Disable metrics for libverifproxy only
* Update confutils
* missing import
* build proxy in tests
* more build stuff
* namespace make vars
* export NimMain for windows
* reduce dependency on Nim compiler in header file
* copyright

* Completed draft implementation of witness JSON-RPC endpoints for portal network bridge.
* Updated Nimbus RPC configuration to support enabling experimental endpoints.
* Moved witness verification tests.
* Added json test for getProof.
* Added main procs to new tests to fix test suite.
* Added getBlockWitness test to blockchain json test suite.
* Added tests for experimental RPC endpoints and improved the API to support returning state proofs from before or after block execution.
* Correctly rollback transaction in getBlockWitness proc.
* Improve logging and logging options in Fluffy
- Allow selection of log format, including:
- JSON
- automatic selection based on tty
- Allow log levels per topic configured on cli
* Somewhat tighten error handling
why:
Zombie state is invoked when the current peer turns out to be useless
for further communication. While there is a chance to further talk
to a peer about another topic (aka healing) after some protocol failure,
it makes no sense to do so after a network problem.
The latter state is explained bu the `peerDegraded` flag that goes
together with the `zombie` state flag. A degraded peer is dropped
immediately.
* Remove `--sync-mode=snapCtx` option, always start snap in recovery mode
why:
No need for a snap sync option without recovery mode, can be achieved
by deleting the database.
* Code cosmetics, typos, prettify logging, debugging helper, etc.
* Split off snap sync sub-mode handler into separate modules
details:
The original `worker.nim` source has become a multiplexer for several
snap sync sub-modes `full` and `snap`. The source modules of the
incarnations of a particular sync sub-mode are places into the
`worker/play` directory.
* Update ticker for snap and full sync logging
* Clean up some function prototypes
why:
Simplify polymorphic prototype variances for easier maintenance.
* Fix fringe condition crash when importing bogus RLP node
why:
Accessing non-list RLP entry as a list causes `Defect`
* Fix left boundary proof at range extractor
why:
Was insufficient. The main problem was that there was no unit test for
the validity of the generated left boundary.
* Handle incomplete left boundary proofs early
why:
Attempt to do it later leads to overly complex code in order to prevent
looping when the same peer repeats to send the same incomplete proof.
Contrary, gaps in the leaf sequence can be handled gracefully with
registering the gaps
* Implement a manual pivot setup mechanism for snap sync
why:
For a test scenario it is convenient to set the pivot to something
lower than the beacon header from the consensus layer. This does not
need rely on any RPC mechanism.
details:
The file containing the pivot specs is specified by the
`--sync-ctrl-file` option. It is regularly parsed for updates.
* Fix calculation error
why:
Prevent from calculating negative square root
* Enable `snap/1` accounts range service
* Allow to change the garbage collector to `boehm` as a Makefile option.
why:
There is still an unsolved memory corruption problem that might be
related to the standard `gc`. It seemingly goes away if the `gc` is
changed to `boehm`.
Specifying another `gc` on the make level simplifies debugging and
development.
* Code cosmetics
details:
* updated exception annotations
* extracted `worker_desc.nim` from `full/worker.nim`
* etc.
* Implement option to state a sync modifier file
why:
This allows to specify extra sync type specific options which might
change over time. This file is regularly checked for updates.
* Implement a threshold when to suspend full syncing
why:
For a test scenario, a full sync beep may work as a local snap server.
There is no need to download the full block chain.
details:
The file containing the pivot specs is specified by the
`--sync-ctrl-file` option. It is regularly parsed for updates.
* Removed some Windows specific unit test annoyances
details:
+ Short put()/get() cycles on persistent database have a race condition
with vendor rocksdb. On a specific (and slow) qemu/win7 a 50ms `sleep()`
in between will mostly do the job (i.e. unless heavy CPU load.) This
issue was not observed on github/ci.
+ Removed annoyances when qemu/Win7 keeps the rocksdb database files
locked even after closing the db. The problem is solved by strictly
using fresh names for each test. No assumption made to be able to
properly clean up. This issue was not observed on github/ci.
* Silence some compiler gossip -- part 7, misc/non(sync or graphql)
details:
Adding some missing exception annotation
* Reduce Nim 1.6 compiler warnings/hints for Fluffy and Nimbus proxy
Mostly raises Defect removals, TaintedString removal and some
unnecessary imports.
Also updating the copyright years alongside.
* Further reduce Nim 1.6 compiler warnings/hints for Nimbus
* Silence some compiler gossip -- part 5, common
details:
Mostly removing redundant imports and `Defect` tracer after switch
to nim 1.6
* Silence some compiler gossip -- part 6, db, rpc, utils
details:
Mostly removing redundant imports and `Defect` tracer after switch
to nim 1.6
* Silence some compiler gossip -- part 7, randomly collected source files
details:
Mostly removing redundant imports and `Defect` tracer after switch
to nim 1.6
* Silence some compiler gossip -- part 8, assorted tests
details:
Mostly removing redundant imports and `Defect` tracer after switch
to nim 1.6
* Clique update
why:
More impossible exceptions (undoes temporary fix from previous PR)
* Cosmetics, update logger `topics`
* Clean up sync/start methods in nimbus
why:
* The `protocols` list selects served (as opposed to sync) protocols only.
* The `SyncMode.Default` object is allocated with the other possible sync
mode objects.
* Add snap service stub to `nimbus`
* Provide full set of snap response handler stubs
* Bicarb for the latest CI hiccup
why:
Might be a change in the CI engine for MacOS.
* Stop negotiating pivot if peer repeatedly replies w/usesless answers
why:
There is some fringe condition where a peer replies with legit but
useless empty headers repetely. This goes on until somebody stops.
We stop now.
* Rename `missingNodes` => `sickSubTries`
why:
These (probably missing) nodes represent in reality fully or partially
missing sub-tries. The top nodes may even exist, e.g. as a shallow
sub-trie.
also:
Keep track of account healing on/of by bool variable `accountsHealing`
controlled in `pivot_helper.execSnapSyncAction()`
* Add `nimbus` option argument `snapCtx` for starting snap recovery (if any)
also:
+ Trigger the recovery (or similar) process from inside the global peer
worker initialisation `worker.setup()` and not by the `snap.start()`
function.
+ Have `runPool()` returned a `bool` code to indicate early stop to
scheduler.
* Can import partial snap sync checkpoint at start
details:
+ Modified what is stored with the checkpoint in `snapdb_pivot.nim`
+ Will be loaded within `runDaemon()` if activated
* Forgot to import total coverage range
why:
Only the top (or latest) pivot needs coverage but the total coverage
is the list of all ranges for all pivots -- simply forgotten.
* 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
