* 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
* Add `stop()` methods to shutdown to shutdown procedure
why:
Nasty behaviour when hitting Ctrl-C, otherwise
* Add background service to sync scheduler
why:
The background service will be used for sync data import and recovery
after restart.
It is controlled by the sync scheduler for an easy turn/on off API.
also:
Simplified snap ticker time calc.
* Fix typo
* Update log ticker, using time interval rather than ticker count
why:
Counting and logging ticker occurrences is inherently imprecise. So
time intervals are used.
* Use separate storage tables for snap sync data
* Left boundary proof update
why:
Was not properly implemented, yet.
* Capture pivot in peer worker (aka buddy) tasks
why:
The pivot environment is linked to the `buddy` descriptor. While
there is a task switch, the pivot may change. So it is passed on as
function argument `env` rather than retrieved from the buddy at
the start of a sub-function.
* Split queues `fetchStorage` into `fetchStorageFull` and `fetchStoragePart`
* Remove obsolete account range returned from `GetAccountRange` message
why:
Handler returned the wrong right value of the range. This range was
for convenience, only.
* Prioritise storage slots if the queue becomes large
why:
Currently, accounts processing is prioritised up until all accounts
are downloaded. The new prioritisation has two thresholds for
+ start processing storage slots with a new worker
+ stop account processing and switch to storage processing
also:
Provide api for `SnapTodoRanges` pair of range sets in `worker_desc.nim`
* Generalise left boundary proof for accounts or storage slots.
why:
Detailed explanation how this works is documented with
`snapdb_accounts.importAccounts()`.
Instead of enforcing a left boundary proof (which is still the default),
the importer functions return a list of `holes` (aka node paths) found in
the argument ranges of leaf nodes. This in turn is used by the book
keeping software for data download.
* Forgot to pass on variable in function wrapper
also:
+ Start healing not before 99% accounts covered (previously 95%)
+ Logging updated/prettified
* For snap sync, publish `EthWireRef` in sync descriptor
why:
currently used for noise control
* Detect and reuse existing storage slots
* Provide healing module for storage slots
* Update statistic ticker (adding range factor for unprocessed storage)
* Complete mere function for work item ranges
why:
Merging interval into existing partial item was missing
* Show av storage queue lengths in ticker
detail;
Previous attempt shows average completeness which did not tell much
* Correct the meaning of the storage counter (per pivot)
detail:
Is the # accounts that have a storage saved
* Miscellaneous updates TBC
* Disentangled pivot2 module from snap
why:
Wrote as template on top of sync so it can be shared by fast and snap
sync.
* Renamed and relocated pivot sources
* Integrated `best_pivot` module into full and snap sync
why:
Full sync used an older version of `best_pivot`
* isolating download module from full sync
why;
might be shared with snap sync at a later stage
* Provided common scheduler API, applied to `full` sync
* Use hexary trie as storage for proofs_db records
also:
+ Store metadata with account for keeping track of account state
+ add iterator over accounts
* Common scheduler API applied to `snap` sync
* Prepare for accounts bulk import
details:
+ Added some ad-hoc checks for proving accounts data received from the
snap/1 (will be replaced by proper database version when ready)
+ Added code that dumps some of the received snap/1 data into a file
(turned of by default, see `worker_desc.nim`)
