BTC_unused.h and BTC_unused.cpp now contain this code. We may remove it
some day but now we leave it for illustrative purposes as it makes heavy
use of the bitcoin api.
We no longer store the headers in memory. We keep them in the db. We
don't need them that often and clients can just read them from the db
if/when needed. Hopefully rocksdb is peppy enough. We can cache them if
it's a problem.
Also refactored some stuff around and simplified the storage code a
little bit.
When reading data from bitcoind, we can assume the hex data it gives us
is good and there is no need to validate on a per-character basis.
Thus, we use ParseHexFast to shave off cpu cycles (it's like 6x faster
than Qt's fromHex()).
This, along with the Util::ToHexFast() (which is 60% faster than
QByteArray::toHex()), will be used in performance critical code.
This hex parser is 5-6x faster than what we were using before, although
it does no real verification that the input is hex digits. Usable with
results returned from bitcoind, which is never going to be
malicious/malformed and thus we can rely on this non-checking hex
parser for the performance it offers (at the expense of verification).
Controller will manage BitcoinD and perhaps synching to bitcoind. It can
"see" all the servers as well as bitcoind.
Also refactored things a little bit and added some more startup sanity
checks.
Note internally the BTC::Address class just stores hash160.
Its ToString() is always legacy (for now), but the server can now accept
both legacy or cash address from clients. Class c'tor for
BTC::Address() auto-detects address type and decodes it appropriately.
- Util::RunInThread to run a lambda in a thread
- App exit handling cleanup
- EXMgr uses an id for clients now
- EXMgr keeps track of lagging clients
- EXMgr more aggressive with reconnects if no valid exclients
- Nits and refactorings and misc. cleanup
