Merge #12437: [Trivial] Simplify if-else blocks and more descriptive variable naming
97bcd36811 [Trivial] Simplify if-else blocks and more descriptive variable naming (Jeff Rade)

Pull request description:

  Was looking through `test_runner.py` to start work on [#11964](https://github.com/bitcoin/bitcoin/issues/11964).  Made a few changes to make the file more readable and keep these separate from future PR.

Merge #12683: Fix more constness violations in serialization code
172f5fa738 Support deserializing into temporaries (Pieter Wuille)
2761bca997 Merge READWRITEMANY into READWRITE (Pieter Wuille)

Pull request description:

  This is another fragment of improvements from #10785.

  The current serialization code does not support serializing/deserializing from/to temporaries (like `s >> CFlatData(script)`). As a result, there are many invocations of the `REF` macro which in addition to changing the reference type also changes the constness. This is unnecessary in C++11 as we can use rvalue references now instead.

  The first commit is an extra simplification we can make that removes the duplication of code between `READWRITE` and `READWRITEMANY` (and related functions).

499d95e278 Add static_assert to prevent VARINT(<signed value>)
Using VARINT with signed types is dangerous because negative values will appear
to serialize correctly, but then deserialize as positive values mod 128.

This commit changes the VARINT macro to trigger an error by default if called
with an signed value, and updates broken uses of VARINT to pass a special flag
that lets them keep working with no change in behavior.

1ee72a819f qt: Avoid querying unnecessary model data when filtering transactions (João Barbosa)

Pull request description:

  This change moves down model data querying to where it's needed. The worst case remains the same (all data is queried and the row passes) but for the average case it improves the filter performance.

Remove redundant checks for MSG_* from configure.ac
It is redundant to check for the presence of MSG_NOSIGNAL macro in
configure.ac, define HAVE_MSG_NOSIGNAL and then check whether the later
is defined in the source code. Instead we can check directly whether
MSG_NOSIGNAL is defined. Same for MSG_DONTWAIT.

In addition to that, the checks we had in configure.ac produce a
compiler warning about unused variable and thus could fail if
-Werror is present and erroneously proclaim that the macros are
not available.

Merge #12431: Only call NotifyBlockTip when chainActive changes
f98b54352 Only call NotifyBlockTip when the active chain changes (James O'Beirne)
152b7fb25 [tests] Add a (failing) test for waitforblockheight (James O'Beirne)

Pull request description:

  This is a subset of the more controversial https://github.com/bitcoin/bitcoin/pull/12407, but this also adds a test demonstrating the bug.

  In InvalidateBlock, we're calling NotifyBlockTip with the now-invalid block's prev regardless of what chain the ancestor block is on. This could create numerous issues, but it at least screws up `waitforblockheight` (or anything else relying on `rpc/blockchain.cpp:latestblock`) when InvalidateBlock is called on a block not in chainActive, which can happen via RPC.

  Only call NotifyBlockTip when the block being marked invalid is on the active chain.

6ef99826b9 Actually disable BnB when there are preset inputs
We don't want to use BnB when there are preset inputs because there
is some weirdness with making that work with using the KnapsackSolver
as the fallback. Currently we say that we haven't used bnb when
there are preset inputs, but we don't actually disable BnB. This fixes
that.

Pull request description:

  This is an implementation of the [Branch and Bound coin selection algorithm written by Murch](http://murch.one/wp-content/uploads/2016/11/erhardt2016coinselection.pdf) (@xekyo). I have it set so this algorithm will run first and if it fails, it will fall back to the current coin selection algorithm. The coin selection algorithms and tests have been refactored to separate files instead of having them all in wallet.cpp.

  I have added some tests for the new algorithm and a test for all of coin selection in general. However, more tests may be needed, but I will need help with coming up with more test cases.

  This PR uses some code borrowed from #10360 to use effective values when selecting coins.

a128bdc9e1 [wallet] Construct CWalletTx objects in CommitTransaction (Russell Yanofsky)

Pull request description:

  Two commits:

  - `Construct CWalletTx objects in CommitTransaction` moves a bunch of CWalletTx initialization into CWallet::CommitTransaction to dedup some code and avoid future inconsistencies in how wallet transactions are created.
  - `Get rid of CWalletTx default constructor` does what is described and eliminates the possibility of empty transaction entries being inadvertently created by mapWallet[hash] accesses.

  Both of these changes were originally part of #9381

  ```
  ./configure --enable-debug

  Seems to be caused by acquiring `cs_main` inside `CWallet::ComputeTimeSmart` in #11041.

172f5fa738 Support deserializing into temporaries
Currently, the READWRITE macro cannot be passed any non-const temporaries, as
the SerReadWrite function only accepts lvalue references.

Deserializing into a temporary is very common, however. See for example
things like 's >> VARINT(n)'. The VARINT macro produces a temporary wrapper
that holds a reference to n.

Fix this by accepting non-const rvalue references instead of lvalue references.
We don't propagate the rvalue-ness down, as there are no useful optimizations
that only apply to temporaries.

Then use this new functionality to get rid of many (but not all) uses of the
'REF' macro (which casts away constness).

33eb9071b9 Fix ComputeTimeSmart test failure with -DDEBUG_LOCKORDER
Failure looks like:

    Entering test case "ComputeTimeSmart"
    test_bitcoin: sync.cpp💯 void potential_deadlock_detected(const std::pair<void*, void*>&, const LockStack&, const LockStack&): Assertion `false' failed.
    unknown location(0): fatal error in "ComputeTimeSmart": signal: SIGABRT (application abort requested)
    wallet/test/wallet_tests.cpp(566): last checkpoint

Reproducible with:

    ./configure --enable-debug
    make -C src test/test_bitcoin && src/test/test_bitcoin --log_level=test_suite --run_test=wallet_tests/ComputeTimeSmart

Happens due to "92fabcd443 Add LookupBlockIndex function" which acquires
cs_main from inside CWallet::ComputeTimeSmart.

  Replace all `mapBlockIndex` lookups with the new `LookupBlockIndex()`. In some cases it avoids a second lookup.

Merge #12658: Sanitize some wallet serialization
42343c748 Split up and sanitize CAccountingEntry serialization (Pieter Wuille)
029ecac1b Split up and sanitize CWalletTx serialization (Pieter Wuille)

Pull request description:

  This is a small subset of changes taken from #10785, fixing a few of the craziest constness violations in the serialization code.

  `CWalletTx` currently serializes some of its fields by embedding them in a key-value `mapValue`, which is modified (and then fixed up) even from the `Serialize` method (for which `mapValue` is const). `CAccountingEntry` goes even further in that it stores such a map by appending it into `strComment` after a null char, which is again later fixed up again.

  Fix this by splitting the serialization and deserialization code, and making the serialization act on a copy of `mapValue` / `strComment`.

fa06dfce0 [rpc] createrawtransaction: Accept sorted outputs (MarcoFalke)
8acd25d85 rpc: Allow typeAny in RPCTypeCheck (MarcoFalke)

Pull request description:

  The second parameter of the `createrawtransaction` is a dictionary of the outputs. This comes with at least two drawbacks:

  * In case of duplicate keys, either of them might silently disappear, with no user feedback at all. A user needs to make other mistakes, but this could eventually lead to abnormal tx fees.
  * A dictionary does not guarantee that keys are sorted. Again, a user needs to keep this in mind, as it could eventually lead to excessive tx fees.

  Even though my scenario of loss-of-funds is unlikely to happen, I see it as a inconvenience that should be fixed.

Pull request description:

  The util function `sync_blocks` already checks for equal chains, so we can remove the unused `sync_chain`.

  Also cleaned up the errors that are printed in case of timeout:

6a34ff5335 Have SelectCoinsMinConf and SelectCoins use BnB or Knapsack and use it
Allows SelectCoinsMinConf and SelectCoins be able to switch between
using BnB or Knapsack for choosing coins.

Has SelectCoinsMinConf do the preprocessing necessary to support either
BnB or Knapsack. This includes calculating the filtering the effective
values for each input.

Uses BnB in CreateTransaction to find an exact match for the output.
If BnB fails, it will fallback to the Knapsack solver.
