60ebc7da4c trivial: Mark overrides as such. (Daniel Kraft)
Pull request description:
This trivial change adds the `override` keyword to some methods that override virtual base class / interface methods. This ensures that any future changes to the interface's method signatures which are not correctly mirrored in the subclasses will break at compile time with a clear error message, rather than at runtime.

This removes the need to include rpc/blockchain.cpp in order to put
GetDifficulty under test. GetDifficulty was called in two ways:
* with a guaranteed non-null blockindex
* with no argument
Change the latter case to be provided chainActive.Tip() explicitly.
This trivial change adds the "override" keyword to some methods of
subclasses meant to override interface methods. This ensures that any
future change to the interface' method signatures which are not correctly
mirrored in the subclass will break at compile time with a clear error message,
rather than fail at runtime (which is harder to debug).
Updating the input explicitly requires the caller to present a mutable
input, which more clearly communicates the effects and intent of the method.
In most cases, this input is already immediately available and need not be
looked up.
9aac9f90d5 replace modulus with FastMod (Martin Ankerl)
Pull request description:
Not sure if this is optimization is necessary, but anyway I have some spare time so here it is. This replaces the slow modulo operation with a much faster 64bit multiplication & shift. This works when the hash is uniformly distributed between 0 and 2^32-1. This speeds up the benchmark by a factor of about 1.3:
```
RollingBloom, 5, 1500000, 3.73733, 4.97569e-07, 4.99002e-07, 4.98372e-07 # before
RollingBloom, 5, 1500000, 2.86842, 3.81630e-07, 3.83730e-07, 3.82473e-07 # FastMod
```
Be aware that this changes the internal data of the filter, so this should probably
not be used for CBloomFilter because of interoperability problems.

ReserveKeyFromKeyPool's previous behaviour is to set nIndex to -1 if the keypool is
empty, OR throw an exception for technical failures. Instead, we now return false
if the keypool is empty, true if the operation succeeded.
This is to make failure more easily detectable by calling code.
labels are associated with addresses (rather than addresses being
associated with labels, as was the case with accounts). The
getlabeladdress does not make sense in this model, so remove it.
getaccountaddress is still supported for one release as the accounts
API is deprecated.

ecc3c4a Do not unlock cs_main in ABC unless we've actually made progress. (Matt Corallo)
Pull request description:
Originally this PR was just to add tests around concurrency in block validation - those tests seem to have uncovered another bug in ActivateBestChain - this now fixes that bug and adds tests.
ActivateBestChain (invoked after a new block is validated) proceeds in steps - acquiring and releasing cs_main while incrementally disconnecting and connecting blocks to sync to the most work chain known (FindMostWorkChain()). Every time cs_main is released the result of FindMostWorkChain() can change - but currently that value is cached across acquisitions of cs_main and only refreshed when an invalid chain is explored. It needs to be refreshed every time cs_main is reacquired. The test added in 6094ce7304 will occasionally fail without the commit fixing this issue 26bfdbaddb
Original description below
--
After a bug discovered where UpdatedBlockTip() notifications could be triggered out of order (#12978), these unit tests check certain invariants about these signals.
The scheduler test asserts that a SingleThreadedSchedulerClient processes callbacks fully and sequentially.
The block validation test generates a random chain and calls ProcessNewBlock from multiple threads at random and in parallel. ValidationInterface callbacks verify that the ordering of BlockConnected BlockDisconnected and UpdatedBlockTip events occur as expected.

The new `loadwallet` RPC method allows an existing wallet to be loaded
dynamically at runtime.
`unloadwallet` and `createwallet` are not implemented. Notably,
`loadwallet` can only be used to load existing wallets, not to create a
new wallet.
Pass an error message back from CWallet::Verify(), and call
InitError/InitWarning from WalletInit::Verify().
This means that we can call CWallet::Verify() independently from
WalletInit and not have InitErrors printed to stdout. It also means that
the error can be reported to the user if dynamic wallet load fails.
This allows a single wallet to be verified. Prior to this commit, all
wallets were verified together by the WalletInit::Verify() function at
start-up.
Individual wallet verification will be done when loading wallets
dynamically at runtime.
After a recent bug discovered in callback ordering in MainSignals,
this test checks invariants in ordering of
BlockConnected / BlockDisconnected / UpdatedChainTip signals
WalletInit::Start calls postInitProcess() for each wallet. Previously
each call to postInitProcess() would attempt to schedule wallet
background flushing.
Just start wallet background flushing once from WalletInit::Start().

In `ProcessGetBlockData`, send the block data directly from disk if
type MSG_WITNESS_BLOCK is requested. This is a valid shortcut as the
on-disk format matches the network format.
This is expected to increase performance because a deserialization and
subsequent serialization roundtrip is avoided.
chain.h does not actually depend on the methods defined in pow.h, just its
include of consensus/params.h, which is standalone and can be included instead.
Confirmed by inspection and successful build.
f08a385590 [qt]: changes sendcoinsdialog's box layout for improved readability. (marcoagner)
Pull request description:
I'm addressing two (probably duplicate) issues: https://github.com/bitcoin/bitcoin/issues/11606 and https://github.com/bitcoin/bitcoin/issues/10613.
Some points worth noting:
- I've tried to balance the proposed changes on both issues without going too far and remaining a bit conservative. It will be easier to improve based on suggestions where necessary.
- I preferred to maintain a layout that doesn't ask for an address truncation because, in my view, this wallet should be conservative on this.
- I didn't follow the idea of aligning the amounts to the right for finding it more natural (and minimalist) to read the information without having to map alignments. Additionally, that approach seems to need more `<hr />`'s (or similar) in order to help the user to map information, which ended up cluttering the box too much (specially with multiple recipients). Thus, I preferred to just give some more space between recipients. Let me know if there are better ideas on this.
Visually, I went from this (current):

Pull request description:
Add compile time checking for `cs_wallet` runtime locking assertions.
This PR is a subset of #12665. The PR was broken up to make reviewing easier.
The intention is that literally all `EXCLUSIVE_LOCKS_REQUIRED`/`LOCKS_EXCLUDED`:s added in this PR should follow either directly or indirectly from `AssertLockHeld(…)`/`AssertLockNotHeld(…)`:s already existing in the repo.
Consider the case where function `A(…)` contains `AssertLockHeld(cs_foo)` (without
first locking `cs_foo` in `A`), and that `B(…)` calls `A(…)` (without first locking `cs_main`):
* It _directly_ follows that: `A(…)` should have an `EXCLUSIVE_LOCKS_REQUIRED(cs_foo)` annotation.
* It _indirectly_ follows that: `B(…)` should have an `EXCLUSIVE_LOCKS_REQUIRED(cs_foo)` annotation.

Pull request description:
According to the BerkeleyDB docs, the DbEnv handle may not be accessed
after close() has been called. This change ensures that we create a new
handle after close() is called. This avoids a segfault when the first
connection attempt fails and then a second connection attempt tries to
call open() on the already closed DbEnv handle.
Without the patch, bitcoindd reliably crashes in the second call to `set_lg_dir()` after `close()` if
there is an issue with the database:

Revival/rebase of #11085
Adds a new command `sethdseed` which allows you to either set or generate a new HD seed to be used. A new keypool can be generated or the original one kept and new keys added to the keypool will come from the new HD seed.
Wallets that are not HD will be upgraded to be version FEATURE_HD_SPLIT when the `sethdseed` RPC command is used.
I have also add some tests for this.
Additionally `-upgradewallet` can now be used to upgrade a wallet from non-HD to HD. When it is used for such an upgrade, the keypool will be regenerated.

This commit adds a boolean option `-enablebip61`, defaulting to `1`, that
can be used to disable the sending of BIP61 `reject` messages. This
functionality has been requested for various reasons:
- security (DoS): reject messages can reveal internal state that can be
used to target certain resources such as the mempool more easily.
- bandwidth: a typical node sends lots of reject messages; this counts
against upstream bandwidth. Also the reject messages tend to be larger
than the message that was rejected.
On the other hand, reject messages can be useful while developing client
software (I found them indispensable while creating bitcoin-submittx),
as well as for our own test cases, so whatever the default becomes on the
long run, IMO the functionality should be retained as option. But that's
a discussion for later.

Bump the wallet version to indicate support for the pre split keypool.
Also prevents any wallets from upgrading to versions between HD_SPLIT
and PRE_SPLIT_KEYPOOL.
After upgrading to HD chain split, we want to continue to use keys
from the old keypool. To do this, before we generate any new keys after
upgrading, we mark all of the keypool entries as being pre-chain
split and move them to a separate pre chain split keypool. Keys are
fetched from that keypool until it is emptied. Only then are the new
internal and external keypools used.
Changes the maximum upgradewallet version to the latest wallet version
number, 159900. Non-HD wallets will be upgraded to use HD derivation.
Non HD chain split wallets will be upgraded to HD chain split.
If a non-HD wallet is upgraded to HD, the keypool will be entirely
regenerated.
Since upgradewallet is effectively run during a first run, all of the
first run initial setup stuff is combined with the upgrade to HD
If multiple threads are invoking ActivateBestChain, it was possible to have
them working towards different tips, and we could arrive at a less work tip
than we should. Fix this by introducing a ChainState lock which must
be held for the entire duration of ActivateBestChain to enforce
exclusion in ABC.
Technically, some internal datastructures may be in an inconsistent
state if we do this, though there are no known bugs there. Still,
for future safety, its much better to only unlock cs_main if we've
made progress (not just tried a reorg which may make progress).

43f3dec00 Remove enum specifier (to avoid re-declare scoped enum as unscoped) (donaloconnor)
Pull request description:
MSVC fails to compile with the changes made in #10742
The problem is enum types were changed to scoped (`enum class`) but in some places `enum` as an unscoped is used.
This is a very simple fix and I've tested it.
Edit: Had to remove enum altogether - `enum class` doesn't compile on clang.

fad63eb [logging] Don't incorrectly log that REJECT messages are unknown. (John Newbery)
Pull request description:
Reject messages are logged to debug.log if NET debug logging is enabled.
Because of the way the `ProcessMessages()` function is structured,
processing for REJECT messages will also drop through to the default
branch and incorrectly log `Unknown command "reject" from peer-?`. Fix
that by exiting from `ProcessMessages()` early.

Replaces the slow modulo operation with a much faster 32bit multiplication & shift. This works
because the hash should be uniformly distributed between 0 and 2^32-1. This speeds up the benchmark
by a factor of about 1.3:
RollingBloom, 5, 1500000, 3.73733, 4.97569e-07, 4.99002e-07, 4.98372e-07 # before
RollingBloom, 5, 1500000, 2.86842, 3.81630e-07, 3.83730e-07, 3.82473e-07 # FastMod
Be aware that this changes the position of the bits that are toggled, so this should probably
not be used for CBloomFilter which is serialized.
A transaction with 1 segwit input and 1 P2WPHK output has non-witness size of 82 bytes. Anything smaller than this have unnecessary malloc overhead and are not relayed/mined.
This disables OP_CODESEPARATOR in non-segwit scripts (even in an unexecuted branch), and makes a positive FindAndDelete result invalid. This ensures that the scriptCode serialized in SignatureHash() is always the same as the script passing to the EvalScript.
Reject messages are logged to debug.log if NET debug logging is enabled.

processing for REJECT messages will also drop through to the default

CWallet::ScanForWalletTransactions did not previously take into account
pindexStop when calculating progress.
Renamed progress vars to progress_*.
rescanblockchain is the only rpc that uses this parameter.
According to the BerkeleyDB docs, the DbEnv handle may not be accessed
after close() has been called. This change ensures that we create a new
handle after close() is called. This avoids a segfault when the first
connection attempt fails and then a second connection attempt tries to
call open() on the already closed DbEnv handle.

d76962e rpc: Reduce cs_main lock in listunspent (João Barbosa)
Pull request description:
On my system, where the wallet has 10000 unspents, the `cs_main` lock duration changed from 191ms to 36ms. The loop that generates the response takes around 155ms. So, the lock duration is reduced to around 20%.

1e46d8a Get rid of ambiguous OutputType::NONE value (Russell Yanofsky)
Pull request description:
Based on suggestion by @sipa https://github.com/bitcoin/bitcoin/pull/12119#issuecomment-357982763
After #12119, the NONE output type was overloaded to refer to either an output type that couldn't be parsed, or to an automatic change output mode. This change drops the NONE enum and uses a simple bool to indicate parse failure, and a new CHANGE_AUTO enum to refer the change output type.
This change is almost a pure refactoring except it makes RPCs reject empty string ("") address types instead of treating them like they were unset. This simplifies the parsing code a little bit and could prevent RPC usage mistakes. It's noted in the release notes.

Previously, ChainStateFlushed would fire either if a full flush

on its own DATABASE_WRITE_INTERVAL timer) *or* on a
ChainStateFlushed-specific DATABASE_WRITE_INTERVAL timer. This is
both less clear for clients (as there are no guarantees about a
flush having actually happened prior to the call), and reults in
extra flushes not clearly intended by the code. We drop the second
case, providing a strong guarantee without removing the periodit
timer-based flushing.
This is a follow-up to discussion in #11857.

`LogPrintStr` returns the number of characters printed. This number is
doubled if both logging to console and logging to file is enabled. As
the return value is never used, I've opted to remove it instead of try

66dc662c8a Add compile time checking for all cs_KeyStore runtime locking assertions (practicalswift)
Pull request description:
Add compile time checking for all `cs_KeyStore` runtime locking assertions.
This PR is a subset of #12665. The PR was broken up to make reviewing easier.
The intention is that literally all `EXCLUSIVE_LOCKS_REQUIRED`/`LOCKS_EXCLUDED`:s added in this PR should follow either directly or indirectly from `AssertLockHeld(…)`/`AssertLockNotHeld(…)`:s already existing in the repo.
Consider the case where function `A(…)` contains `AssertLockHeld(cs_foo)` (without
first locking `cs_foo` in `A`), and that `B(…)` calls `A(…)` (without first locking `cs_main`):
* It _directly_ follows that: `A(…)` should have an `EXCLUSIVE_LOCKS_REQUIRED(cs_foo)` annotation.
* It _indirectly_ follows that: `B(…)` should have an `EXCLUSIVE_LOCKS_REQUIRED(cs_foo)` annotation.

7da3b0a rpc: Move RPC_FORBIDDEN_BY_SAFE_MODE code to reserved section (Wladimir J. van der Laan)
2ae705d Remove Safe mode (Andrew Chow)
Pull request description:
Rebase of #10563. Safe mode was [disabled by default and deprecated in 0.16](https://github.com/bitcoin/bitcoin/blob/master/doc/release-notes/release-notes-0.16.0.md#safe-mode-disabled-by-default), so probably should be removed for 0.17.
> Rationale:
>
> Safe mode is useless. It only disables some RPC commands when large work forks are detected. Nothing else is affected by safe mode. It seems that very few people would be affected by safe mode. The people who use Core as a wallet are primarily using it through the GUI, which safe mode does not effect. In the GUI, transactions will still be made as normal; only a warning is displayed.
>
> I also don't think that we should be disabling RPC commands or any functionality in general. If we do, it should be done consistently, which safe mode is not. If we want to keep the idea of a safe mode around, I think that the current system needs to go first before a new system can be implemented.

Although this code is no longer ever sent back after removing safe mode,
it would be unwise to remove it from the header.
For one, it would be bad to accidentally re-use the number.
Also some API documentation / bindings are directly generated from the .h
file - this is why the "Aliases for backward compatibility" are there. We don't
want to break code that relies on this error code existing, even if it's never
generated.
So keep it around but move it to a reserved section.

Pull request description:
Currently our wallet code will treat bare multisig outputs (meaning scriptPubKeys with multiple public keys + `OP_CHECKMULTISIG` operator in it) as ours without the user asking for it, as long as all private keys in it are in our wallet.
This is a pointless feature. As it only works when all private keys are in one place, it's useless compared to single key outputs (P2PK, P2PKH, P2WPKH, P2SH-P2WPKH), and worse in terms of space, cost, UTXO size, and ability to test (due to lack of address format for them).
Furthermore, they are problematic in that producing a list of all `scriptPubKeys` we accept is not tractable (it involves all combinations of all public keys that are ours). In further wallet changes I'd like to move to a model where all scriptPubKeys that are treated as ours are explicit, rather than defined by whatever keys we have. The current behavior of the wallet is very hard to model in such a design, so I'd like to get rid of it.
I think there are two options:
* Remove it entirely (do not ever accept bare multisig outputs as ours, unless watched)
* Only accept bare multisig outputs in situations where the P2SH version of that output would also be acceptable
This PR implements the first option. The second option was explored in #12874.
