We deleted the non-working merge operator for scripthash_unspent.. and
we do a read-modify-write for each new utxo/spend per scripthash.
It's very slow though.
I may have to defer updating this table until the very end from the utxo
set or something. This is unacceptably bad...
we weren't adding the right txidx to the history. Good thing I also
added debug code to this commit to check history.
Fixed!
Also various other nits and tweaks. Added the /debug endpoint for
sending params for debugging to the server.
RocksDB is super fast. Keeping it in memory was a waste of memory. This
is much faster and reduced memory consumption significantly.
TODO: Maybe do the same thing for headers as well!
Also: We need to save txNum to DB. We're not saving it now resulting in
correctness errors on subsequent reloads of same db.
Also in this commit various nits and subtle bugs prevented.
Refactored the 'Stats' mechanism to return a generic QVariant rather
than QVariantMap, which is more flexible.
Misc. other nits.
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.
It works! I still haven't figured out how to provoke the dreaded
"Workdepth exceeded" error .. but we pretty much drop the connection
anyway on anything too unexpected from bitcoind.
When the bitcoind manager class is written it will back off and try
again if too many disconnects happen.
For now though, the code we have is fast and works well against
bitcoind.
I restricted the possible underlying types it can contain down to
qint64, QString, and nullptr_t. This should make it more type safe since
we don't want it to inadvertently end up holding lists or maps
(previously it was a straight up QVariant).
It has a conversion to QVariant so it should work nicely.
On Windows it still prints to console, however (without timestamps).
Note that syslog mode doesn't produce any debug output even if -d is
specified (at least on macOS) -- probably the sysadmin needs to
enable debug logging.
- 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
- Already supports listening on as many sockets as you wish
- Each listening server has its own thread
- Will implement later: SSL server
Also refactored code a bit, created the generic "Controller" class, made
EXMgr and SrvMgr inherit from it.
ToDo: Figure out workflow for connections and clients, model client
sessions, etc.
- Made the stale timeout be 2 mins now
- Check clients runs every 1 minute
- Added 'Controller' ABC which EXMgr is one of and the TcpServer will be
another.
