It was only called twice, and in very close proximity. The class didn't
add anything.
This improves readability and with the new state its easier to write
too.
Merkle-block and merkle-tree classes and methods are pretty much stand-
alone and can be moved with no efforts.
Also move the relevent unit test to qtestlib.
Allow user to shutdown a connection, making it instantly invalid.
Allow user to register a callback for errors.
And fix pinging to be disabled on legacyP2P style connections.
This was always the intention, but the satoshi code was stupid and buggy.
First, the 'version has been seen' flag was set even if there was a parsing
error in it.
Second, ignoring messages (up to 100) until a version message was seen
makes no sense. Just disconnect instantly.
The API changes in boost between 1.66 and later was the need
for the boost_compat.h header file.
Its been a long time since Flowee started demanding 1.67 minimum
for boost, making this compat obsolete.
Using the forget() method too many times could lead to an invalid
(negative size) ConstBuffer being created.
This fixes and immediately copies an assert used in many other places in
the code already.
When the UTXO saved checkpoints this change makes sure we also store the
index-db changes.
Since we stopped saving simple state changes fromt the index-db, the
only real data we save is the 'undo-block-index', as such this will be
relatively cheap to save.
Without an undo block position we will currently fail to verify those
blocks and as such it is useful to save all at the same time to actually
have a state we can start from.
This allows the pruner to be used on the 'tip' DB file, at which point it
will set the filesize to be the default 2GB one.
Previously pruning the tip would confuse the Hub with a smaller file
size.
This change drops the various arguments that force the user to select if
an argument is an .info file or a .db file etc. Instead auto-detect them
and also allow the user to provide a list of arguments.
The most direct effect is that I can now run 'unspent-db info *.info"
