Pull request description:

  This is an updated version of https://github.com/bitcoin/bitcoin/pull/25287 and the next steps in parent PR #25203 implementing, with Klement Tan, user-configurable, per-category severity log levels based on an idea by John Newbery and refined in GitHub discussions by Wladimir Van der Laan and Marco Falke.

  - simplify the `BCLog::Level` enum class and the `LogLevelToStr()` function and add documentation
  - update the logging logic to filter logs by log level both globally and per-category
  - add a hidden `-loglevel` help-debug config option to allow testing setting the global or per-category severity level on startup for logging categories enabled with the `-debug` configuration option or the logging RPC (Klement Tan)
  - add a `trace` log severity level selectable by the user; the plan is for the current debug messages to become trace, LogPrint ones to become debug, and LogPrintf ones to become info, warning, or error

  ```
  $ ./src/bitcoind -help-debug | grep -A10 loglevel
    -loglevel=<level>|<category>:<level>
         Set the global or per-category severity level for logging categories
         enabled with the -debug configuration option or the logging RPC:
         info, debug, trace (default=info); warning and error levels are
         always logged. If <category>:<level> is supplied, the setting
         will override the global one and may be specified multiple times
         to set multiple category-specific levels. <category> can be:
         addrman, bench, blockstorage, cmpctblock, coindb, estimatefee,
         http, i2p, ipc, leveldb, libevent, lock, mempool, mempoolrej,
         net, proxy, prune, qt, rand, reindex, rpc, selectcoins, tor,
         util, validation, walletdb, zmq.
  ```

    One final push per `git range-diff a5d5569 ce3c4c9 9580480` (should be trivial to re-ACK) to ensure this pull changes no default behavior in any way for users or the tests/CI in order to be completely v24 compatible, to update the unit test setup in general, and to update the debug logging section in the developer notes.

Bitcoin Core

Setup

Bitcoin Core is the original Bitcoin client and it builds the backbone of the network. It downloads and, by default, stores the entire history of Bitcoin transactions, which requires a few hundred gigabytes of disk space. Depending on the speed of your computer and network connection, the synchronization process can take anywhere from a few hours to a day or more.

To download Bitcoin Core, visit bitcoincore.org.

Running

The following are some helpful notes on how to run Bitcoin Core on your native platform.

Unix

Unpack the files into a directory and run:

  • bin/bitcoin-qt (GUI) or
  • bin/bitcoind (headless)

Windows

Unpack the files into a directory, and then run bitcoin-qt.exe.

macOS

Drag Bitcoin Core to your applications folder, and then run Bitcoin Core.
