Configuration
---

- `bitcoind` and `bitcoin-qt` will now raise an error on startup if a datadir that is being used contains a bitcoin.conf file that will be ignored, which can happen when a datadir= line is used in a bitcoin.conf file. The error message is just a diagnostic intended to prevent accidental misconfiguration, and it can be disabled to restore the previous behavior of using the datadir while ignoring the bitcoin.conf contained in it.
init: Error if ignored bitcoin.conf file is found Show an error on startup if a bitcoin datadir that is being used contains a `bitcoin.conf` file that is ignored. There are two cases where this could happen: - One case reported in https://github.com/bitcoin/bitcoin/issues/27246#issuecomment-1470006043 happens when a bitcoin.conf file in the default datadir (e.g. $HOME/.bitcoin/bitcoin.conf) has a "datadir=/path" line that sets different datadir containing a second bitcoin.conf file. Currently the second bitcoin.conf file is ignored with no warning. - Another way this could happen is if a -conf= command line argument points to a configuration file with a "datadir=/path" line and that specified path contains a bitcoin.conf file, which is currently ignored. This change only adds an error message and doesn't change anything about way settings are applied. It also doesn't trigger errors if there are redundant -datadir or -conf settings pointing at the same configuration file, only if they are pointing at different files and one file is being ignored. 2023-03-21 14:14:53 -03:00			`Configuration`
