In my benchmarks, using this pool allocator for CCoinsMap gives about
20% faster `-reindex-chainstate` with -dbcache=5000 with practically the
same memory usage. The change in max RSS changed was 0.3%.
The `validation_flush_tests` tests need to be updated because
memory allocation is now done in large pools instead of one node at a
time, so the limits need to be updated accordingly.
|
|
This frees up all associated memory with the map, not only the nodes.
This is necessary in preparation for using the PoolAllocator for
CCoinsMap, which does not actually free any memory on clear().

to generate semi-random CAmounts up to MAX_MONEY rather
than only uint32, and use it in the unit tests.

as many of the unit tests don't use this code

Use {Chain,}TestingSetup's existing {Chainstate,Block}Manager and avoid
unnecessarily creating a local one.
This also helps reduce the code diff for a later commit where we change
{Chainstate,Block}Manager's constructor signature.

After this commit, there should be no explicit instantiation of
CTxMemPool in src/test other than those in fuzz/ and setup_common

Add an upwards reference to chainstate instances to the owning
ChainstateManager. This is necessary because there are a number
of `this_chainstate == chainman.ActiveChainstate()` checks that
will happen (as a result of assumeutxo) in functions that otherwise
don't have an easily-accessible reference to the chainstate's
ChainManager.

Unnecessary argument since we can make use of this->m_mempool
Co-authored-by: John Newbery <john@johnnewbery.com>

Since we now have multiple chainstate objects, only one of them is active at any given
time. An active chainstate has a mempool, but there's no point to others having one.
This change will simplify proposed assumeutxo semantics. See the discussion here:

Also adds CCoinsViewCache::ReallocateCache() to attempt to free
memory that the cacheCoins's allocator may be hanging onto when
downsizing the cache.
Adds `CChainState::m_coins{tip,db}_cache_size_bytes` data members
so that we can reference cache size on a per-chainstate basis for
flushing.
