25bc17fceb08ee9625c5e09e2579117ec6f7a1c5 refactor: rpc: Remove vector copy from listtransactions (João Barbosa)
Pull request description:
Current approach
- copy accumulated `ret` vector to `arrTmp`
- drop unnecessary elements from `arrTmp`
- reverse `arrTmp`
- clear `ret`
- copy `arrTmp` to the `ret`
New approach
- create a vector from the accumulated `ret` with just the necessary elements already reversed
- copy it to the result
This PR doesn't change behavior.

bf36a3ccc212ad4d7c5cb8f26d7a22e279fe3cec gui: Fix race in WalletModel::pollBalanceChanged (Russell Yanofsky)
Pull request description:
Poll function was wrongly setting cached height to the current chain height instead of the chain height at the time of polling.
This bug could cause balances to appear out of date, and was first introduced https://github.com/bitcoin/bitcoin/pull/10244/commits/a0704a8996bb950ae3c4d5b5a30e9dfe34cde1d3#diff-2e3836af182cfb375329c3463ffd91f8L117. Before that commit, there wasn't a problem because cs_main was held during the poll update.
Currently, the problem should be rare. But if 8937d99ce81a27ae5e1012a28323c0e26d89c50b from #17954 were merged, the problem would get worse, because the wrong cachedNumBlocks value would be set if the wallet was polled in the interval between a block being connected and it processing the BlockConnected notification.
MarcoFalke also points out that a0704a8996b could lead to GUI hangs as well, because previously the pollBalanceChanged method, which runs on the GUI thread, would only make a nonblocking TRY_LOCK(cs_main) call, but after could make blocking LOCK(cs_main) calls, potentially locking up the GUI.

Pull request description:
The next step of changes from #10785.
This one adds:
* A meta-formatter for vectors, which serializes the vector elements using another formatter
* Switch the undo.h code to the new framework, using the above (where undo entries are serialized as a vector, each of which uses a modified serializer for the UTXOs).

ac57859e53167f4ff3da467b616b0902c93701a9 qt: Fix deprecated QCharRef usage (Hennadii Stepanov)
Pull request description:
From Qt docs:
- [`QKeyEvent::text()`](https://doc.qt.io/qt-5/qkeyevent.html#text):
> Return values when modifier keys such as Shift, Control, Alt, and Meta are pressed differ among platforms and could return an empty string.
- [`QString::operator[]()`](https://doc.qt.io/qt-5/qstring.html#operator-5b-5d):
> **Note:** Before Qt 5.14 it was possible to use this operator to access a character at an out-of-bounds position in the string, and then assign to such a position, causing the string to be automatically resized. Furthermore, assigning a value to the returned `QCharRef` would cause a detach of the string, even if the string has been copied in the meanwhile (and the `QCharRef` kept alive while the copy was taken). These behaviors are deprecated, and will be changed in a future version of Qt.
Since Qt 5.14 this causes a `QCharRef` warning if any modifier key is pressed while the splashscreen is still displayed.
Fix #18080.
Note: Ctrl+Q will also close the spashscreen now.

2af3e16ca917acd85c2d4f709f6d486519d6af0d Qt: pass clientmodel changes from walletframe to walletviews (Jonas Schnelli)
Pull request description:
Fixes #18090
We currently don't pass `clientmodel` changes from the `walletframe` to the `walletviews` leading to possible invalid access during shutdown because all walletviews miss the nullifying of the clientmodel.

Pull request description:
This updates leveldb to currently newest upstream commit https://github.com/bitcoin-core/leveldb/commit/0c40829872a9f00f38e11dc370ff8adb3e19f25b:
- CRC32C hardware acceleration is now an external library [crc32c](https://github.com/google/crc32c). This adds acceleration on ARM, and should be faster on x86 because of using prefetch. It also makes it easy to support similar instruction sets on other platforms in the future.
- Thread handling uses C++11, instead of platform specific code.
- Native windows environment was added. No need to maintain our own hacky one, anymore.
- Upstream now builds using CMake. This doesn't mean we need to use that (phew), but internal configuration changed to a a series of checks, instead of OS profiles. This means the blanket error "Cannot build leveldb for $host. Please file a bug report' is removed.
All changes: https://github.com/google/leveldb/compare/a53934a3ae1244679f812d998a4f16f2c7f309a6...0c40829872a9f00f38e11dc370ff8adb3e19f25b
Pretty much all our changes have been subsumed by upstream, so we figured it was cleaner to start over with a new branch from upstream with the still-relevant patches applied: https://github.com/bitcoin-core/leveldb/tree/bitcoin-fork-new
There's quite some testing to be done (see below). See https://github.com/bitcoin-core/leveldb/issues/25 and https://github.com/bitcoin-core/leveldb/pull/26 for more history and context.
TODO:
- [x] Subtree `crc32c`
- [x] Make linters happy about crc32 subtree
- [x] Integrate `crc32c` library into build system
- [x] MSVC build system

0a50019fde7781263e0c8f041d1d9dcb0dee77e8 Walk pindexBestHeader back to ChainActive().Tip() if it is invalid (Matt Corallo)
Pull request description:
Instead of keeping pindexBestHeader set to the best header we've
ever seen, reset it back to our validated tip if we find an ancestor
of it turns out to be invalid. While the name is now a bit confusing,
this matches much better with how it is used in practice, see below.
Further, this opens up more use-cases for it in the future, namely
aggressively searching for new peers in case we have discovered
(possibly via some covert channel) headers which we do not know to be
invalid, but which we cannot find block data for.
Places pindexBestHeader is used:
* Various GUI displays of the best header and getblockchaininfo["headers"],
I don't think changing this is bad, and if anything this is less confusing
in the presence of an invalid block.
* IsCurrentForFeeEstimation(): If anything I think ensuring pindexBestHeader
isn't some crazy invalid chain is better than the alternative, even in the
case where you are rejecting the current chain due to hardware error (since
hopefully in that case you won't get any new blocks anyway).
* ConnectBlock assumevalid checks: We use pindexBestHeader to check that the
block we're connecting leads to something with nMinimumChainWork (preventing
a user-set assumevalid from having bogus work) and that the block we're
connecting leads to pindexBestHeader (I'm not too worried about this one -
it's nice to "disable" assumevalid if we have a long invalid headers chain,
but I don't see it as a critical protection).
* BlockRequestAllowed() uses pindexBestHeader as its target to ensure the
requested block is within a month of the "current chain". I don't think this
is a meaningful difference, if we're rejecting the current tip we're
trivially fingerprintable anyway, and if the chain really does have a bunch
of invalid crap near the tip, using the best not-invalid header is likely a
better criteria.
* ProcessGetBlockData uses pindexBestHeader as the "current chain" definition
of whether a block request is "historical" for the purpose of bandwidth
limiting. Similarly, I don't see why this is a meaningful change.
* We use pindexBestHeader for requesting missing headers on receipt of a
headers/compact block message or block inv as well as for initial getheaders.
I think this is definitely wrong, using the best not-invalid header for such
requests is much better.
* We use pindexBestHeader to define the "current chain" for deciding when
we're close to done with initial headers sync. I don't think this is a
meaningful change.
* We use pindexBestHeader to decide if initial headers sync has timed out. If
we're rejecting the chain due to hardware error this may result in
additional cases where we ban a peer, but this is already true, so I think
its fine.

bd5a02692853f7240a4fdc593d7d0123d7916e45 Make UpdateTransactionsFromBlock use Epochs (Jeremy Rubin)
2ccb7cca4ac67198ac89bd58f5b4ae41a5163ceb Add Epoch Guards to CTXMemPoolEntry and CTxMemPool (Jeremy Rubin)
Pull request description:
UpdateTransactionsFromBlock is called during a re-org. When a re-org occurs, all of the transactions in the mempool may be descendants from a transaction which is in the pre-reorg block. This can cause us to propagate updates, worst case, to every transaction in the mempool.
Because we construct a `setEntries setChildren`, which is backed by a `std::set`, it is possible that this algorithm is `O(N log N)`.
By using an Epoch visitor pattern, we can limit this to `O(N)` worst case behavior.
Epochs are also less resource intensive than almost any set option (e.g., hash set) because they are allocation free.
This PR is related to https://github.com/bitcoin/bitcoin/pull/17268, it is a small subset of the changes which have been refactored slightly to ease review. If this PR gets review & merge, I will follow up with more PRs (similar to #17268) to improve the mempool

This PR builds on #17578 (now merged) and deprecates the rpc getaddressinfo `label` field. The deprecated behavior can be re-enabled by starting bitcoind with `-deprecatedrpc=label`.
See http://www.erisian.com.au/bitcoin-core-dev/log-2019-11-22.html#l-622 and https://github.com/bitcoin/bitcoin/pull/17283#issuecomment-554458001 for more context.
Reviewers: This PR may be tested manually by building, then running bitcoind with and without the `-deprecatedrpc=label` flag while verifying the rpc getaddressinfo output and help text.
Next step: add support for multiple labels.

a029e18c2bf67dd00552b0f4bbc85fa2fa5b973b Use rolling bloom filter of recent block tx's for AlreadyHave() check (Suhas Daftuar)
Pull request description:
In order to determine whether to download or process a relayed transaction, we first try to check whether we already have the transaction -- either in the mempool, in our filter of recently rejected transactions, in our orphan pool, or already confirmed in a block.
Prior to this commit, the heuristic for checking whether a transaction was confirmed in a block is based on whether there's a coin cache entry corresponding to the 0- or 1-index vout of the tx. While that is a quick check, it is very imprecise (eg if those outputs were already spent in another block, we wouldn't detect that the transaction has already been confirmed) -- we can do better by just keeping a rolling bloom filter of the transactions in recent blocks, which will better capture the case of a transaction which has been confirmed and then fully spent.
This should reduce the bandwidth that we waste by requesting transactions which will not be accepted to the mempool.
To avoid relay problems for transactions which have been included in a recent block but then reorged out of the chain, we clear the bloom filter whenever a block is disconnected.

When a developer is examining `debug.log` after something goes wrong, it's often useful to know the exact options the failing instance of `bitcoind` was started with.

1b96a3cd1ebe725896f59614903184289fe62cf8 tests: reset fIsBareMultisigStd after bare-multisig tests (fanquake)
Pull request description:
Fixes: #18015
The bug this fixes is two-part.
1. The `fIsBareMultisigStd` global is being reused by other tests,
such as [script_p2sh_tests(set)](https://github.com/bitcoin/bitcoin/blob/master/src/test/script_p2sh_tests.cpp#L150), after being set to false.
2. The order our tests run in doesn't always? seem to be random,
which meant that the `script_p2sh` tests would only fail if they
were run in an order where the `transaction_tests` ran first,
mutating the `fIsBareMultisigStd` global.
This doesn't seem to happen when running make check, but if you
run `src/test/test_bitcoin and pass --random=99999`, the failure
in `script_p2sh` will occur (on most, but maybe not all systems):
```bash
src/test/test_bitcoin --random=99999
Running 389 test cases...
test/script_p2sh_tests.cpp:200: error: in "script_p2sh_tests/set": txTo[1].IsStandard

The new test for bare multisig was introduced in #17502.
