* 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
was
--min-gas-price=[STRING]
Minimum amount of Wei per GAS to be paid for a
transaction to be accepted for mining. Overrides
--basic-tx-usd.
Issue: --basic-tx-usd does not exist. Author probably meant
--usd-per-tx.
New:
--min-gas-price=[STRING]
Minimum amount of Wei per GAS to be paid for a
transaction to be accepted for mining. Overrides
--usd-per-tx.
* use tempdir instead of devtools in kvdb-rocksdb
* use tempdir instead of devtools in migration
* use tempdir instead of devtools in ethcore-network
* fixed wrong merge
While the standard defined by Trezor as the default derivation path here
https://blog.trezor.io/trezor-integration-with-myetherwallet-3e217a652e08
says that it should be `m/44'/60'/0`, in practice they don't have an
implementation of a wallet for Ethereum themselves and refer customers
to MEW.
MEW has a custom implementation of the path derivation logic that allows them to
generate multiple addresses by essentially adding `/0`, `/1` etc to the path.
In my initial implementation of Trezor I didn't take this into
consideration unfortunately and just used the keypath that Trezor
themselves recommended. However, given that it's seemingly standard
practice to append `/0` for a "sub-address" (and this is what we've done
for Ledger as well) it seems like a mistake on my part to not take that
into consideration.
Unfortunately, anyone who has used their Trezor device with Parity
previously would now see a different address when they connect the
Trezor device the next time. The only way they would have to access the
old address is to use an old version, or by going through MEW and
selecting the Ledger keypath.
