Assume that when a wallet transaction has a valid block hash and transaction position
in it, the transaction is actually there. We're already trusting wallet data in a
much more fundamental way anyway.
To prevent backward compatibility issues, a new record is used for storing the
block locator in the wallet. Old wallets will see a wallet file synchronized up
to the genesis block, and rescan automatically.

Since the introduction of the ScriptForMining callback, the mining
functions (setgenerate and generate) crash with an assertion failure
(due to a NULL pointer script returned) if the keypool is empty. Fix
this by giving a proper error.

Declare some arguments of functions as "const" pointers where they are
not meant to be modified.

No longer relevant after #5957. This hack existed because of another
hack where the numthreads parameter, on regtest, doubled as how many
blocks to generate.

4716267 Use real number of cores for default -par, ignore virtual cores (Wladimir J. van der Laan)
|
|
To determine the default for `-par`, the number of script verification
threads, use [boost::thread::physical_concurrency()](http://www.boost.org/doc/libs/1_58_0/doc/html/thread/thread_management.html#thread.thread_management.thread.physical_concurrency)
which counts only physical cores, not virtual cores.
Virtual cores are roughly a set of cached registers to avoid context
switches while threading, they cannot actually perform work, so spawning
a verification thread for them could even reduce efficiency and will put
undue load on the system.
Should fix issue #6358, as well as some other reported system overload
issues, especially on Intel processors.
The function was only introduced in boost 1.56, so provide a utility
function `GetNumCores` to fall back for older Boost versions.

AcceptBlock will no longer process an unrequested block, unless it has not

28bf062 Fix off-by-one error w/ nLockTime in the wallet (Peter Todd)
|
|
Under some circumstances it is possible for there to be a significant,
discontinuous jump in a node's clock value. On mining nodes, this can
result in block templates which are no longer valid due to time-based
nLockTime constraints. UpdateTime() is modified so that it will never
decrease a block's nLockTime, thereby preventing such invalidations.

da29ecb Consensus: MOVEONLY: Move CValidationState from main consensus/validation (jtimon)
27afcd8 Consensus: Refactor: Decouple CValidationState from main::AbortNode() (Cory Fields)
|
|
Previously due to an off-by-one error the wallet ignored
nLockTime-by-height transactions that would be valid in the next block
even though they are accepted into the mempool. The transactions
wouldn't show up until confirmed, nor would they be included in the
unconfirmed balance. Similar to the mempool behavior fix in 665bdd3b,
the wallet code was calling IsFinalTx() directly without taking into
account the fact that doing so tells you if the transaction could have
been mined in the *current* block, rather than the next block.
To fix this we strip IsFinalTx() of non-consensus-critical
functionality, removing the default arguments, and add CheckFinalTx() to
check if a transaction will be final in the next block.

GetBlockSubsidy]
Remove redundant getter CChainParams::SubsidyHalvingInterval()
|

When the internal miner is enabled at the start of a new node, there
is an near instant assert in TestBlockValidity because its attempting
to mine a block before the top checkpoint.
Also avoids a data race around vNodes.

This reverts commit e2edf95cd3f43331843676e49a82830128a95050 6b04508e37c5dd18cec1cd61cc4356bd208aa991 0df67f1f7ab4adfe9f0b3ba6276e737b37826464,
except the changes to the RPC tests.
A `generate` RPC call is introduced based on the old code.

- I saw this on http://en.cppreference.com/w/cpp/language/try_catch and
thought it would be a good idea
- also unify used format to better be able to search for exception
uses in our codebase
