* kvdb-rocksdb: update to RocksDB 5.8.8
* kvdb-rocksdb: tune RocksDB options
* Switch to level-style compaction
* Increase default block size (16K), and use bigger blocks for HDDs (64K)
* Increase default file size base (64MB SSDs, 256MB HDDs)
* Create a single block cache shared across all column families
* Tune compaction settings using RocksDB helper functions, taking into account
memory budget spread across all columns
* Configure backgrounds jobs based on the number of CPUs
* Set some default recommended settings
* ethcore: remove unused config blockchain.db_cache_size
* parity: increase default value for db_cache_size
* kvdb-rocksdb: enable compression on all levels
* kvdb-rocksdb: set global db_write_bufer_size
* kvdb-rocksdb: reduce db_write_bufer_size to force earlier flushing
* kvdb-rocksdb: use master branch for rust-rocksdb dependency
The error is "PoW too low to compete with other messages"
This has been previously reported in #7144
Solution: prevent the move semantics
The source of the error is in PoolHandle.relay
implementation for NetPoolHandle.
Because of the move semantics, `res` variable is in fact
copied (as it implements Copy) into the closure and for
that reason, the returned result is always `false.
* created the dir crate in util
* moved code from ethstore/src/dir/paths.rs to dir crate
* rename dir module in ethstore to accounts_dir to distinguish it
from the dir crate
* changes after @tomusdrw on #6952
* parity-version module split from util
removed unused util deps and features
trigger buildbot again
only kvdb links rocksdb
snappy linker issues
* rm snappy
* fixed old version imports
* fix#6228: do not display eth price in cli for etc
Current behaviour:
When the client is started with defaults, the miner's gas calibrator
periodically queries the price of ether in usd and uses it to adjust
the wei_per_gas variable, displaying an info message in the cli each
time calibration happens. The info message mentions the price of ETH.
When started with the --min-gas-price option, the calibrator is inactive
and the price is not displayed.
Problem:
When running on an alternate chain such as ethereum classic, the info
message mentioning the ETH price is present, unless the --min-gas-price
option is used.
Solution:
if chain != foundation and --min-gas-price is not set,
don't use GasPricerConfig::Calibrated as default but rather fix
the minimum gas price to zero.
* self.chain() returns ChainType.
* match chain based on SpecType
