Should we do the same for `process_message`? would need to change it to use `ProcessMessagesOnce` as well.

Tracepoints are OS level hooks that are not part of the software by default. Logging is about keeping the history of events that occurred along the software lifetime. This does not only involve errors, it also involves information about the soft activity.
Unlike logging, which can be enabled on-the-fly by simply calling an RPC command, users cannot enable tracepoints on their node without recompiling the software with a specific flag. Which requires compiling knowledge, forces the user to shutd

This was lowered to 1 tried and 1 new in https://github.com/bitcoin/bitcoin/pull/23084 as more than one address meant the test could sporadically fail if there's a collision.

@stratospher, I think, if you want to make this clearer, you could have this commit be a revert of https://github.com/bitcoin/bitcoin/commit/5825b34783545f9470d5ab94b87c918980715675 or note it in the commit message.

Nice, but I am not sure if we want to go down to route to put everyone back into the makefile hell, because this will just make writing new fuzz tests bloaty and impossible to maintain/review (Who is going to read those repetitive and ugly 1k LOC of build code). (Unrelated: Not even sure how this will interact with cmake)

It seems easier to just put a one-line bash command into the readme to achieve the same, for anyone that needs it (oss-fuzz, fuzz-introspector, afl-lto, etc ...).

Happy

Happy to review a pull request, or happy to include any patch here, that compiles, if someone writes it.

I split the harnesses into individual files so that we can use the file list in `src/test/fuzz` as the harness list. It should be possible to use that to have a loop (?) in the makefile to build each binary instead of the hard-coded list I have here (I haven't figured out how to do that yet). If that works, adding a new fuzz harness becomes easier as no makefile would need to be edited.

Avoid timeouts such as https://github.com/bitcoin/bitcoin/issues/28812#issuecomment-1842914664

This is done by:

* Limiting the maximum number of iterations if the maximum size of the container is "large" (see the magic numbers in the code).
* Check the equality only once. This should be fine, because if a crash were to happen in the equality check, but the crash doesn't happen if further iterations were run, the fuzz engine should eventually find the crash by truncating the fuzz input.

> turns out we can actually keep the map if we just don't add all the harness functions into it

Are you sure on this? I don't know how afl or fuzz-introspector detect reachable code paths, but I'd be surprised if the static analysis can follow a function pointer hidden in a map.
