Pruning
The blockchain prunes seven eighths of prunable tx data.
This saves about two thirds of the blockchain size, while
keeping the node useful as a sync source for an eighth
of the blockchain.
No other data is currently pruned.
There are three ways to prune a blockchain:
- run monerod with --prune-blockchain
- run "prune_blockchain" in the monerod console
- run the monero-blockchain-prune utility
The first two will prune in place. Due to how LMDB works, this
will not reduce the blockchain size on disk. Instead, it will
mark parts of the file as free, so that future data will use
that free space, causing the file to not grow until free space
grows scarce.
The third way will create a second database, a pruned copy of
the original one. Since this is a new file, this one will be
smaller than the original one.
Once the database is pruned, it will stay pruned as it syncs.
That is, there is no need to use --prune-blockchain again, etc.

Pruning
The blockchain prunes seven eighths of prunable tx data.
This saves about two thirds of the blockchain size, while
keeping the node useful as a sync source for an eighth
of the blockchain.
No other data is currently pruned.
There are three ways to prune a blockchain:
- run monerod with --prune-blockchain
- run "prune_blockchain" in the monerod console
- run the monero-blockchain-prune utility
The first two will prune in place. Due to how LMDB works, this
will not reduce the blockchain size on disk. Instead, it will
mark parts of the file as free, so that future data will use
that free space, causing the file to not grow until free space
grows scarce.
The third way will create a second database, a pruned copy of
the original one. Since this is a new file, this one will be
smaller than the original one.
Once the database is pruned, it will stay pruned as it syncs.
That is, there is no need to use --prune-blockchain again, etc.

Purge epee::critical_crap and CRITICAL_CRAP
This purges epee::critical_region/epee::critical_section and the awful
CRITICAL_REGION_LOCAL and CRITICAL_REGION_LOCAL1 and
CRITICAL_REGION_BEGIN1 and all that crap from epee code.
This wrapper class around a mutex is just painful, macro-infested
indirection that accomplishes nothing (and, worse, forces all using code
to use a std::recursive_mutex even when a different mutex type is more
appropriate).
This commit purges it, replacing the "critical_section" mutex wrappers
with either std::mutex, std::recursive_mutex, or std::shared_mutex as
appropriate. I kept anything that looked uncertain as a
recursive_mutex, simple cases that obviously don't recurse as
std::mutex, and simple cases with reader/writing mechanics as a
shared_mutex.
Ideally all the recursive_mutexes should be eliminated because a
recursive_mutex is almost always a design flaw where someone has let the
locking code get impossibly tangled, but that requires a lot more time
to properly trace down all the ways the mutexes are used.
Other notable changes:
- There was one NIH promise/future-like class here that was used in
example one place in p2p/net_node; I replaced it with a
std::promise/future.
- moved the mutex for LMDB resizing into LMDB itself; having it in the
abstract base class is bad design, and also made it impossible to make a
moveable base class (which gets used for the fake db classes in the test
code).

Pruning
The blockchain prunes seven eighths of prunable tx data.
This saves about two thirds of the blockchain size, while
keeping the node useful as a sync source for an eighth
of the blockchain.
No other data is currently pruned.
There are three ways to prune a blockchain:
- run monerod with --prune-blockchain
- run "prune_blockchain" in the monerod console
- run the monero-blockchain-prune utility
The first two will prune in place. Due to how LMDB works, this
will not reduce the blockchain size on disk. Instead, it will
mark parts of the file as free, so that future data will use
that free space, causing the file to not grow until free space
grows scarce.
The third way will create a second database, a pruned copy of
the original one. Since this is a new file, this one will be
smaller than the original one.
Once the database is pruned, it will stay pruned as it syncs.
That is, there is no need to use --prune-blockchain again, etc.
