b9e76f1bf0rpc: Add test for -rpcwaittimeout (Christian Decker)f76cb10d7drpc: Prefix rpcwaittimeout error with details on its nature (Christian Decker)c490e17ef6doc: Add release notes for the `-rpcwaittimeout` cli parameter (Christian Decker)a7fcc8eb59rpc: Add a `-rpcwaittimeout` parameter to limit time spent waiting (Christian Decker) Pull request description: Adds a new numeric `-rpcwaittimeout` that can be used to limit the time we spend waiting on the RPC server to appear. This is used by downstream projects to provide a bit of slack when `bitcoind`s RPC interface is not available right away. This makes the `-rpcwait` argument more useful, since we can now limit how long we'll ultimately wait, before potentially giving up and reporting an error to the caller. It was discussed in the context of the BTCPayServer wanting to have c-lightning wait for the RPC interface to become available but still have the option of giving up eventually ([4355]). I checked with laanwj whether this is already possible ([comment]), and whether this would be a welcome change. Initially I intended to repurpose the (optional) argument to `-rpcwait`, however I decided against it since it would potentially break existing configurations, using things like `rpcwait=1`, or `rpcwait=true` (the former would have an unintended short timeout, when old behavior was to wait indefinitely). ~Due to its simplicity I didn't implement a test for it yet, but if that's desired I can provide one.~ Test was added during reviews.

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) orbin/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.
