CWalletDB now contains a CDB instead of inheriting from it.
This makes it easier to replace the internal transaction with a different
database, without leaking through internals.
Instead, CWalletDB() with a dummy handle will just give you a no-op
database in which writes always succeeds and reads always fail. CDB
already had functionality for this, so just use that.
Abstract database handle from explicit strFilename into
CWalletDBWrapper.
Also move CWallet::Backup to db.cpp - as it deals with representation
details this is a database specific operation.
disconnectnode() can currently only be called with the IP address/port
of the node the user wishes to connect. This commit allows the node to
be disconnected using the nodeid returned by getpeerinfo().
This was a long-standing and annoying problem.
If autogen.sh was not manually run after touching configure.ac,
bitcoin-config.h would not be properly regenerated. This causes very subtle
problems when configure appears to enable a new value, but it does not end up
reflected in the build.
Occasionally I waste a lot of time not remembering that the second parameter to importprivkey must be blank if you intend to stop rescan with "false" as the third parameter.
This makes SetHDMasterKey responsible for maintinaing the CHDChain
version instead of always creating it with the latest version and
making EncryptWallet responsible for keeping the version from
changing.
This removes another callback from block connection logic, making it
easier to reason about the wallet-RPCs-returns-stale-info issue.
UpdatedTransaction was previously used by the GUI to display
coinbase transactions only after they have a block built on top of
them. This worked fine for in most cases, but only worked due to a
corner case if the user received a coinbase payout in a block
immediately prior to restart. In that case, the normal process of
caching the most recent coinbase transaction's hash would not work,
and instead it would only work because of the on-load -checkblocks
calling DisconnectBlock and ConnectBlock on the current tip.
In order to make this more robust, a full mapWallet loop after the
first block which is connected after restart was added.
