* 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.
* oneshot channels instead of custom promises
* Future instead of handle_dispatch
* Even less copying
* Those explicit waits were a mistake, thanks, @tomusdrw
* No more unsafe polling
* Test for the new `is_done()` method
* Mark Futures as `#[must_use]`
* Solve most compilation warnings
* `try_ready!` is more ideomatic
* Turn spaces into tabs
* Documentation and visibility improvements
* Minor code style improvements
* Make Futures run on an explisit reactor
* Another round of code style issues
* Simplify ConfirmationReceiver type
* Flatten ConfirmationOutcome into a plain Result type
* Get rid of a separate `pending` set, it was a stupid idea
* Clarify `add_request` docs
* No need to reduce the scope of the mutex here
