Currently difficulty adjustment violations are not reported for
chains that branch off before the last checkpoint. Change this
by moving the checkpoint check after the difficulty check.
This commit adds basic keypool mark-used and topup:
- try to topup the keypool on initial load
- if a key in the keypool is used, mark all keys before that as used and
try to top up
Safemode is almost useless as is-- it only triggers in limited
cases most of which aren't even concerning. There have been
several proposals to remove it. But as a simpler, safer, and
more flexible first case, simply deactivate it by default.
Anyone who wants it can re-enable and know what they've signed up for.
This is necessary because core_write has to write amounts in
TxToUniv, and mistakingly uses FormatMoney for that
(which is only for debugging).
We don't move AmountFromValue at the same time, as
this is more challenging due to the RPCError depencency
there.
- Increase `BLOCK_CHAIN_SIZE` from 120GB to 150GB
- Increase `CHAIN_STATE_SIZE` from 2GB to 4GB
I took the local sizes of the blocks and chainstate directory, and added
a bit extra to accomodate the near future (15GB for the chain and 1GB
for the chainstate).
When running test_bitcoin under Valgrind I found the following issue:

The read of the uninitialized variable nLocalServices is triggered by g_connman->GetLocalServices()
in getnetworkinfo(const JSONRPCRequest& request) (net.cpp:462):
```c++
UniValue getnetworkinfo(const JSONRPCRequest& request)
{
...
if(g_connman)
obj.push_back(Pair("localservices", strprintf("%016x", g_connman->GetLocalServices())));
...
}
```
The reason for the uninitialized nLocalServices is that CConnman::Start(...) is not called
by the tests, and hence the initialization normally performed by CConnman::Start(...) is
not done.
This commit adds a method Init(const Options& connOptions) which is called by both the
constructor and CConnman::Start(...). This method initializes nLocalServices and the other
relevant values from the supplied Options object.
This fixes a few cases where we should be treating a restart-after-
coinsviewdb-reset identically to a just-reset-coinsviewdb.
Thanks to @morcos for identifying the bug.
This more clearly uses fReindex vs fReset to make sure we're not
clearing our coinsdb needlessly when restarting after a reindex.
It also makes it so that restarting after shutting down mid-reindex
isn't treates specially at all during txdb loading code, as it
shouldn't be.
This resolves a possible-assert-on-shutdown race introduced in
1f668b6468 when early shutdown
occurs.
Previously this was not done to avoid any cases where the
threadGroup might not exit due to a blocking thread, but at this
point the threadGroup isn't used all that much, plus Qt already
does this, and its good to keep their init/shutdown consistent.
For those curious, the threadGroup is only used in a few places:
* Its used to run the CCheckQueues in script validation, but these
use the boost mutex/condition variable primitives, so they
respect the interrupt pretty trivially.
* Its used for the import thread, which should exit rather quickly
as mostly it just calls LoadExternalBlockFile, which has an
interruption_point right before each block loaded.
* Its used in the scheduler thread, which is only used for:
* validationinterface has an effectively-dummy reference to it.
* wallet compaction, which should not last long
* addr/banlist dumping from CConnman, which should also be fast
