    UPD 2023-04-18. See a shortlist here.

    This is a tracking issue for the long-term goal to replace all of the RecursiveMutex instances with the Mutex ones throughout the code base.

    Anthony Williams (C++ Concurrency in Action, 2019, 3.3.3 Recursive locking):

    Most of the time, if you think you want a recursive mutex, you probably need to change your design instead.

    Anthony Towns, #19303 (comment):

    … the actual goal is “make locking logic easier to follow” rather than “remove RecurviseMutex”

    Should be noted, to insure that mutex locking policy has not been changed by accident in non-trivial cases, all of the related code branches must be covered by appropriate lock assertions: AssertLockHeld() or AssertLockNotHeld().

    Also Clang Thread Safety Analysis annotations with Negative Capabilities are very useful (see #19249) but are not a panacea, of course :)

    From IRC discussion on 2020-06-18:

    <sipa> recursive mutexes are evil <sipa> there is probably a place for them, like goto <sipa> but almost always, they just lead to badly designed abstractions <sipa> a clear design should have code that operates outside the critical section, and code that operates inside <sipa> but not code that works in both <gwillen> my impression is that the usual better approach is to have Foo() which calls Foo_locked(), and callers who already hold the mutex can call the latter directly <sipa> indeed

    +0.5 concept ACK for this as a low-priority janitorial project, since it can make code easier to reason about. I wouldn’t prioritize working on this over working on user-visible bugfixes and improvements. I wouldn’t even prioritize this over similar cleanups like removing cases of gui blocking #16874 (comment). But it is better to do this than not to do this.

    I don’t mind trivial to review changes that are obviously correct and only replace RecursiveMutex with Mutex like commit 1a9ef1d398dd14728b6bc67a89139cdf827c9753. More invasive refactors are hard to prioritize due to the conflicts they cause with non-refactoring changes.

    It is assumed that there will be no non-refactoring changes (e.g., #19306).

    Makes sense, provided the actual goal is “make locking logic easier to follow” rather than “remove RecurviseMutex” – if removing RecursiveMutex makes the code/reasoning more complex, it’s not a good idea. (The if (mempool_locked) stuff in #19306 seems more complex, for instance)

    @ajtowns

    Makes sense, provided the actual goal is “make locking logic easier to follow” rather than “remove RecurviseMutex”…

    Sure! The final goal is to “make locking logic easier to follow”. Btw, I’ve started this work while reasoning about issues like #17397.

    … if removing RecursiveMutex makes the code/reasoning more complex, it’s not a good idea.

    I think the opposite. Adding simple wrappers to differentiate functions by mutex locking condition does not make the code/reasoning more complex. This refactoring just reveals the actual code comlexity.

    The if (mempool_locked) stuff in #19306 seems more complex, for instance

    Yes, I’ve used this stuff in 72f7486b5ebe96762c5d5a68849c61e58c812ffd and 21787abedd7a0808c0175a0b1d795df97fd3b970 as a quick-and-dirty solution to fix broken tests.

    FWIW, I’m not able to reproduce “deadlock” TSan warning using clang-14 starting from 9996b1806a189a9632c9f5023489eb47bf87ca05 when depends can be compiled. Last time the warning was observed for clang-10.

    You should be able to see it in the tsan CI task or with libc++ locally?

    The TSan CI job is pretty stable @ 760651214cd205b91804bc1c40a31c614d3aa26c, and removing the deadlock:Chainstate::ConnectTip suppression does not cause any failure.

    My guess is that this is a byproduct of clang upgrade.
