It was suggested in https://github.com/bitcoin/bitcoin/pull/31624#discussion_r2081363131 already - but I can do it in a follow-up as well, since I'm working on optimizing these checks anyway - and if you think this comment helps, let's add it, I won't block.

Thank you @ismaelsadeeq for your feedback & @ryanofsky for having mercy on this PR. :)

Aiming to address some of the remaining feedback in a follow-up PR next week.

Since it's been merged already, I'll add some more context here:

AFAIK all existing calls to `assert_raises_message` had `message==None`. In this PR I wanted to use it in a later commit. The old way of checking `e.error['message']` instead of `repr(e)` for occurrences of `message` was assuming a certain structure/layout of the exception type. Not sure if there's more to say.

I'm not married to using `repr(e)` (as indicated https://github.com/bitcoin/bitcoin/pull/30660#discussion_r206162010

The ignored errors map are more of a categorization, while I intentionally wanted to include the full representation for the one latest error. I agree there is a drawback in them looking like different errors. Maybe something like this would be better?

```
AssertionError: [node 0] Unable to connect to bitcoind after 60s. Ignored errors: {'missing_credentials': 240}, latest error: 'missing_credentials'/ValueError('No RPC credentials').
```

One remaining `\n`, which would probably fail on Windows. Agree it is marginally more readable.

> I think I will prefer the previous one as there is a case where the test node has start without a cookie file

If you can pinpoint a specific test that calls `stop_node()` without setting up some kind of RPC connection, let me know. Without being able to send the stop-RPC, we have no way of signalling the node to shut down AFAIK. We should be calling something like `TestNode.kill_process()` instead for such cases. So, seems like a logic error worthy of an assert.

I like your final version for its simplicity and also being more correct as currently we only mutate the first found instance.

Concept NACK.

There's already more than enough garbage in the Bitcoin chain thanks to the Ordinals Taproot hijacking. There's no need to make it even easier for people to spam the chain.

> Good point. It's used in at least the `TransactionView::bumpedFee` signal, which might be broken now.

Tested that manually and it seems to work as expected. There is no change in visual behavior between this PR and master when fee bumping from the gui.

📝 theuni opened a pull request: "thread-safety: fix annotations with REVERSE_LOCK"
(https://github.com/bitcoin/bitcoin/pull/32465)
This is one of several PRs to cleanup/modernize our threading primitives.

While replacing the old critical section locks in the mining code with a `REVERSE_LOCK`, I noticed that our thread-safety annotations weren't hooked up to it. This PR gets `REVERSE_LOCK` working properly.

Firstly it modernizes the attributes as-recommended by the [clang docs](https://clang.llvm.org/docs/ThreadSafetyAnalysis.html) (ctrl+f for `USE_LOCK_STYLE_THREAD_SAFETY_ATTRIBUTES`). There's a subtle difference betw

(https://github.com/bitcoin/bitcoin/pull/32466)
This is relatively simple, but done in a bunch of commits to enable scripted diffs.

I wanted to add a semaphore in a branch I've been working on, but it was unclear if I should use `std::counting_semaphore` or stick with our old `CSemaphore`. I couldn't decide, so I just decided to remove all doubt and get rid of ours :)

This replaces our old `CSemaphore` with `std::counting_semaphore` everywhere we used it. `CSemaphoreGrant` is still there as an RAII wrapper, but is now called `CountingSe

As part of an effort to cleanup our threading primitives and add safe `SharedMutex`/`SharedLock` impls, I'd like to get rid of the last of our legacy `ENTER_CRITICAL_SECTION`/`LEAVE_CRITICAL_SECTION` usage. This, along with a follow-up [after fixing REVERSE_LOCK](https://github.com/bitcoin/bitcoin/pull/32465) will allow us to do that.

This replaces the old macros with an RAII lock, while simplifying `CCheckQueueControl`. It now requires a `CCheckQueue`, and optionality is handled externally.

As per the comments, we'll hand over the task to a more suitable developer.
Instead, we plan to proceed with [issue-26756](https://github.com/bitcoin/bitcoin/pull/26756) (we're a developer group based in South-Korea).
This issue involves aligning the behavior of the AvailableCoins method with the getbalance method, which seems well-suited to our expertise.
If you believe this issue isn’t appropriate for us, we’d appreciate it if you could suggest alternative issues.

@sipa these were only the last 30 blocks. In total I let bitcoin-29.0 run for 56 blocks but the performance is so bad compared to when I restart bitcoin-28.0 that something else must be going on. Maybe the debug.log gives you more information?
