  • Update the README.md to mention that a config file can now be used, what format it has to be, and show a sample of how to use it.

I created a config.toml file and tried these params as they are the ones I would use for testnet-11:

testnet=true
utxoindex=true
disable-upnp=true
perf-metrics=true
unsaferpc=true
appdir = "tn11-test"
netsuffix=11
loglevel="info,kaspad_lib::daemon=trace"

appdir seems to be set, but the rest aren't getting set properly.

yes, now that I've tested it more thoroughly it appears that defaults take precedence if exist and clap's get_one() always return Some(default) so unwrap_or() didn't work like I'd expect.

I made a kinda hacky fix for it, it's possible that a refactor for the Args struct so that it's auto parsed using clap's Parser derive macro can be a prettier solution but I didn't want make so many changes.

kaspad/src/args.rs Outdated

if let Some(config_file) = m.get_one::<String>("configfile") {
let config_str = fs::read_to_string(config_file)?;
defaults = from_str(&config_str).map_err(|_| clap::Error::new(clap::error::ErrorKind::ValueValidation))?;

When there's a problem with the config file, the error is only error: invalid value for one of the arguments. Can this be updated so that the error is more descriptive of which config value needs to be fixed?

the parsing of the config is now stricter and provides better errors, like:

error: failed parsing config file, reason: unknown field `blahblah`, expected one of `appdir`, `logdir`, `no-log-files`, `rpclisten`, `rpclisten-borsh`, `rpclisten-json`, `unsafe-rpc`, `wrpc-verbose`, `log-level`, `async-threads`, `connect-peers`, `add-peers`, `listen`, `user-agent-comments`, `utxoindex`, `reset-db`, `outbound-target`, `inbound-limit`, `rpc-max-clients`, `enable-unsynced-mining`, `enable-mainnet-mining`, `testnet`, `testnet-suffix`, `devnet`, `simnet`, `archival`, `sanity`, `yes`, `externalip`, `perf-metrics`, `perf-metrics-interval-sec`, `block-template-cache-lifetime`, `disable-upnp`, `disable-dns-seeding`, `disable-grpc`, `ram-scale`

Testing again with this new config file:

testnet=true
utxoindex=true
disable-upnp=true
perf-metrics=true
unsafe-rpc=true
appdir = "../tn11-test"
testnet-suffix=11
log-level="info,kaspad_lib::daemon=trace"

And it's now using all the params.
