Merge with changes that implement config file PR #15548.
Field *EnsApi string* in swarm/api.Config is replaced with
*EnsAPIs []string*.
A new field *EnsDisabled bool* is added to swarm/api.Config for
easy way to disable ENS resolving with config file.
Signature of function swarm.NewSwarm is changed and simplified.
This commit adds a TOML configuration option to swarm. It reuses
the TOML configuration structure used in geth with swarm
customized items.
The commit:
* Adds a "dumpconfig" command to the swarm executable which
allows printing the (default) configuration to stdout, which
then can be redirected to a file in order to customize it.
* Adds a "--config <file>" option to the swarm executable which will
allow to load a configuration file in TOML format from the
specified location in order to initialize the Swarm node The
override priorities are like follows: environment variables
override command line arguments override config file override
default config.
Allow multiple --ens-api flags to be specified with value format
[tld:][contract-addr@]url.
Backward compatibility with only one --ens-api flag and --ens-addr
flag is preserved and conflict cases are handled:
- multiple --ens-api with --ens-addr returns an error
- single --ens-api with contract address and --ens-addr with
different contract address returns an error
Previously implemented --ens-endpoint is removed. Its functionality
is replaced with multiple --ens-api flags.
* cmd, consensus, eth: split ethash related config to it own
* eth, consensus: minor polish
* eth, consenus, console: compress pow testing config field to single one
* consensus, eth: document pow mode
* cmd, consensus, core, miner: instatx clique for --dev
* cmd, consensus, clique: support configurable --dev block times
* cmd, core: allow --dev to use persistent storage too
This commit introduces a network simulation framework which
can be used to run simulated networks of devp2p nodes. The
intention is to use this for testing protocols, performing
benchmarks and visualising emergent network behaviour.
