Looks like James hardcoded a couple hashes in hard-to-find places, which
caused a unit test to fail. I just changed the hash (which covers UTXO
data which naturally will be different for us on account of our differently
formatted CTxOuts).
TODO: determine how Assumeutxo interacts with the fact that we don't save
out nonces in our normal UTXO serialization. Probably we will need to remove
the nonce from the CCoinStats serialization to avoid having inconsistent
hashes across nodes, since these hashes are now checked in assumeutxo?
Seems odd to have an option for non-deterministic tests
when the goal should be for all tests to be deterministic.
Can be reviewed with `--ignore-all-space`.
1a6323bdbe doc: update developer notes for removal of MakeUnique (fanquake)
3ba2840e7e scripted-diff: remove MakeUnique<T>() (fanquake)
Pull request description:
Since requiring C++17, this is just pointless abstraction. I think we should just "tear the band-aid off" and remove it. Similar to the changes happening in #21366.
Also, having a comment saying this is deprecated doesn't prevent it's usage in new code. i.e : https://github.com/bitcoin/bitcoin/pull/20946#discussion_r561949731.
The repository is fairly quiet at the moment, so any potential complaints about having to rebase should be minimal. Might as well get this over and done with.

b4511e2e2e log: Prefix log messages with function name if -logsourcelocations is set (practicalswift)
Pull request description:
Prefix log messages with function name if `-logfunctionnames` is set.
Yes, exactly like `-logthreadnames` but for function names instead of thread names :)
This is a small developer ergonomics improvement: I've found this to be a cheap/simple way to correlate log output and originating function.
For me it beats the ordinary cycle of 1.) try to figure out a regexp matching the static part of the dynamic log message, 2.) `git grep -E 'Using .* MiB out of .* requested for signature cache'`, 3.) `mcedit filename.cpp` (`openemacs filename.cpp` works too!) and 4.) search for log message and scroll up to find the function name :)
Without any logging parameters:

dc8be12510 refactor: remove boost::thread_group usage (fanquake)
Pull request description:
Post #18710, there isn't much left using `boost::thread_group`, so should just be able to replace it with the standard library. This also removes the last use of `boost::thread_interrupted`.
After this change, last piece of Boost Thread we'd be using is `boost::shared_mutex`. See the commentary [here](https://github.com/bitcoin/bitcoin/issues/16684#issuecomment-726214696) as to why it may be non-trivial to swap that for `std::shared_mutex` in the near future.

This PR:
- gets rid of `boost::thread_group` in the `CCheckQueue` class
- allows thread safety annotation usage in the `CCheckQueue` class
- is alternative to #14464 (https://github.com/bitcoin/bitcoin/pull/18710#issuecomment-616618525, https://github.com/bitcoin/bitcoin/pull/18710#issuecomment-617291612)
Also, with this PR (I hope) it could be easier to resurrect a bunch of brilliant ideas from #9938.

Previously, the validation_chainstatemanager_tests test suite
instantiated its own duplicate ChainstateManager on which tests were
performed.
This wasn't a problem for the specific actions performed in
that suite. However, the existence of this duplicate ChainstateManager
and the fact that many of our validation static functions reach for
g_chainman, ::Chain(state|)Active means we may end up acting on two
different CChainStates should we write more extensive tests in the
future.
This change adds a new ChainTestingSetup which performs all
initialization previously done by TestingSetup except:
1. RPC command registration
2. ChainState initialization
3. Genesis Activation
4. {Ban,Conn,Peer}Man initialization
Means that we will no longer need to initialize a duplicate
ChainstateManger in order to test the initialization codepaths of
CChainState and ChainstateManager.
Lastly, this change has the additional benefit of allowing for
review-only assertions meant to show correctness to work in future work
de-globalizing g_chainman.
In the test chainstatemanager_rebalance_caches, an additional
LoadGenesisBlock call is added as MaybeReblanaceCaches eventually calls
FlushBlockFile, which tries to access vinfoBlockFile[nLastBlockFile],
which is out of bounds when LoadGenesisBlock hasn't been called yet.
-----
Note for the future:
The class con/destructor inheritance structure we have for these
TestingSetup classes is probably not the most suitable abstraction. In
particular, for both TestingSetup and ChainTestingSetup, we need to stop
the scheduler first before anything else. Otherwise classes depending on
the scheduler may be referenced by the scheduler after said classes are
freed. This means that there's no clear parallel between our teardown
code and C++'s destructuring order for class hierarchies.
Future work should strive to coalesce (as much as possible) test and
non-test init codepaths and perhaps structure it in a more fail-proof
way.
This moves the CBlockPolicyEstimator to the NodeContext, which get rids
of two globals and allows us to conditionally create the
CBlockPolicyEstimator (and to remove a circular dep).

Added a method testPeginClaimAcceptance to interfaces::CChain. It is not clear
to me that this is meaningfully different from the existing method broadcastTransaction
(with the `relay` flag set to false so it doesn't actually broadcast), except
that this method returns the TxValidationState, which we display to the user
in the RPC error. Worth revisiting this.
Another nonobvious change was replacing a block of mempool-searching logic
in wallet/rpcwallet.cpp with the single line `pwallet->chain().findCoins(coins)`.
This I stole from the current state of upstream #17211, our favorite in-progress
PR from which the original logic came.
