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.
This includes more fine grained configure options and skipping the
openssl and zlib dependencies when compiling qt. The zlib and libevent
packages are removed.
Number matching semantics are slightly changed: since this is used
as a filter to check whether a number is signed and/or floating
point, we can speed this up further. strto* functions are called
afterwards and will error out where necessary. We now also accept
numbers like .4 which were not accepted before.
The strto* calls on a boost::string_ref will not access unallocated
memory since the parsers always stop at the first bad character,
and the original string is zero terminated.

Depends still contained some leftovers, like the `wallet` target that
included bdb from bitcoin. This commit removes these unneeded targets,
the miniupnpc package and the berkeley db package. Reflect the changes
in the README as well.

It comes before the logger is initialized, so gets displayed
even though it should not be by default, and apparenly comes
too early for (some versions of) Android, where it crashes.
Turns out getting the global shared_ptr hits the profile,
and passing it around still keeps it at close to ~1% CPU,
which is too much for mostly silent logging.
Leak the object instead, which is even safer for late logging.
