We send a 'mempool' p2p command to a peer after we did a series of
merkleblock downloads.
This code adds the mempool p2p command to be sent to peers that didn't
participate in the merkleblock download and thus get the best out of all
our connected peers.
Now we have 3 more logically divided interfaces for the listener
pattern (callbacks).
A P2PNetInterface for peers maintainance.
A DataListenerInterface for the sections getting new data.
And last the new HeaderSyncInterface about the state of the
header-chain (application wide).
Avoid massive connect storm.
Using the network manager based logger we got into a fun situation where
logging to a remote host caused us to connect and fail, which caused us
to log this failed which made us try to connect and .. etc.
The unit tests testing base58 encoding were using univalue JSON
parsing, since we deprecatd univalue to be a hub-private lib
this has now been ported to Qts JSON parser.
Which also makes the clunky cmake hack nice to replace with the
QRC files concept.
As I was in there anyway, the base58 methods being global scope
C-style methods has now been fixed by putting them in a namespace.
As this is not actually used outside of the Hub, it really makes
more sense to make this testing part of the hub testing.
Also makes it easier to compile.
The leveldb and univalue 3rd party libraries are not installed and
not needed by anyone outside of the Hub.
So move them there, making it easier for 3rd party usage.
This sanity check might avoid issues in future code by not assuming a
log channel (or anything it depends on) will avoid using logging at the
moment it is shutting down.
Makes the change from yesterday complete: we now
compress all the chunks into one periodically.
This, again, is done with a timeout instead of on-close.
We have 45 seconds as a timeout to balance between need to save and
waiting long enough to get additional headers should it
have been a while since last run.
This change makes it so that we rely less on the downloaded
blockheader data being only in memory and us saving it when
the client shuts down.
Instead, we save more regularly and we save smaller files
instead of always overwriting the complete downloaded headers.
Having less to save at shutdown is then a happy side-effect.
