Merge #19137: wallettool: Add dump and createfromdump commands
23cac24dd3 tests: Test bitcoin-wallet dump and createfromdump (Andrew Chow)
a88c320041 wallettool: Add createfromdump command (Andrew Chow)
e1e7a90d5f wallettool: Add dump command (Andrew Chow)

Pull request description:

  Adds two commands to the `bitcoin-wallet` tool: `dump` and `createfromdump`. These commands will be useful for a wallet storage migration in the future. It is also generally useful to have a storage agnostic dump like this. These commands are similar to BDB's `db_dump` and `db_load` tools. This can also be useful for manual construction of a wallet file for tests.

  `dump` outputs every key-value pair from the wallet as comma separated hex. Each key-value pair is on its own line with the key and value in hex separated by a comma. This is output to the file specified by the new `-dumpfile` option.

  `createfromdump` takes a file produced by `dump` and creates a new wallet file with exactly the records specified in that file.

  A new option `-dumpfile` is added to the wallet tool. When used with `dump`, the records will be written to the specified file. When used with `createfromdump`, the file is read and the key-value pairs constructed from it. `createfromdump` requires `-dumpfile`.

  A simple round-trip test is added to the `tool_wallet.py`.

  This PR is based on #19334,

Merge #20635: fix misleading comment about call to non-existing function
cc3044ccdb fix misleading comment about call to non-existing function (pox)

Pull request description:

  The comment seems to be describing the subsequent call to `SyncTransaction` but refers to it as `SyncNotifications`, which is not any function currently in the codebase.

  It's best to just remove the "what" aspect of the comment and focus on the "why", which also reduces the risk of similar documentation errors in the future, in case the function ever gets renamed, for example.

Merge #20651: net: Make p2p recv buffer timeout 20 minutes for all peers
ea36a453e3 [net] Make p2p recv buffer timeout 20 minutes for all peers (John Newbery)

Pull request description:

  The timeout interval for the send and recv buffers was changed from 90
  minutes to 20 minutes in commit f1920e86 in 2013, except for peers that
  did not support the pong message (where the recv buffer timeout remained
  at 90 minutes). A few observations:

  - for peers that support BIP 31 (pong messages), this recv buffer
    timeout is almost redundant with the ping timeout. We send a ping
    message every two minutes, and set a timeout of twenty minutes to
    receive the pong response. If the recv buffer was really timing out,
    then the pong response would also time out.
  - BIP 31 is supported by all nodes of p2p version 60000 and higher, and
    has been in widespread use since 2013. I'd be very surprised if there
    are many nodes on the network that don't support pong messages.
  - The recv buffer timeout is not specified in any p2p BIP. We're free to
    set it at any value we want.
  - A peer that doesn't support BIP 31 and hasn't sent any message to us
    at all in 90 minutes is unlikely to be useful for us, and is more likely
    to be evicted AttemptToEvictConnection() since it'll have the worst
    possible ping time and isn't providing blocks/transactions.

  Therefore, we remove this check, and set the recv buffer timeout to 20
  minutes for all peers. This removes the final p2p version dependent
  logic from the net layer, so all p2p version data can move into the
  net_processing layer.

  Alternative approaches:

  - Set the recv buffer timeout to 90 minutes for all peers. This almost
    wouldn't be a behaviour change at all (pre-BIP 31 peers would still
    have the same recv buffer timeout, and we can't ever reach a recv buffer
    timeout higher than 21 minutes for post-BIP31 peers, because the pong
    timeout would be hit first).
  - Stop supporting peers that don't support BIP 31. BIP 31 has been in
    use since 2012, and implementing it is trivial.

Merge #20605: init: Signal-safe instant shutdown
cd03513dc2 init: Signal-safe instant shutdown (Wladimir J. van der Laan)

Pull request description:

  Replace the 200ms polling loop with a faster and more efficient waiting operation. This should speed up short RPC tests.

  This change has been tried a few times before, but abandoned every time because solutions used a condition variable which is not safe for use in signals, as they need to be reentrant.

  On UNIX-ish OSes, use a safe way: a pipe. When shutdown is requested write a dummy byte to the pipe. Waiting for shutdown is a matter of a blocking read from the pipe.

  On Windows, there are no signals so using a condition variable is safe.

  This only affects bitcoind. The GUI is unaffected by this change, and keeps polling as before in `BitcoinGUI::detectShutdown()`. It might be possible to listen to a pipe there, too, but I'm not sure, and it's complicated by the GUI-node abstraction.

fa13e1b0c5 build: Add option --enable-danger-fuzz-link-all (MarcoFalke)
44444ba759 fuzz: Link all targets once (MarcoFalke)

Pull request description:

  Currently the linker is invoked more than 150 times when compiling with `--enable-fuzz`. This is problematic for several reasons:

  * It wastes disk space north of 20 GB, as all libraries and sanitizers are linked more than 150 times
  * It wastes CPU time, as the link step can practically not be cached (similar to ccache for object files)
  * It makes it a blocker to compile the fuzz tests by default for non-fuzz builds #19388, for the aforementioned reasons
  * The build file is several thousand lines of code, without doing anything meaningful except listing each fuzz target in a highly verbose manner
  * It makes writing new fuzz tests unnecessarily hard, as build system knowledge is required; Compare that to boost unit tests, which can be added by simply editing an existing cpp file
  * It encourages fuzz tests that re-use the `buffer` or assume the `buffer` to be concatenations of seeds, which increases complexity of seeds and complexity for the fuzz engine to explore; Thus reducing the effectiveness of the affected fuzz targets

  Fixes #20088

cd03513dc2 init: Signal-safe instant shutdown
Replace the 200ms polling loop with a faster and more efficient waiting
operation.

This was tried a few times before, but given up every time because
solutions use a condition variable which is not safe for use in signals
as they need to be reentrant.

On UNIX-ish OSes, use a safe way: a pipe. When shutdown is requested
write a dummy byte to the pipe. Waiting for shutdown is a matter of a
blocking read from the pipe.

On Windows, there are no signals so using a condition variable is safe.

Pull request description:

  Avoid time-based "non-determinism" in fuzzing harnesses by using mocked `GetTime()`.

  Prior to this commit the fuzzing harnesses `banman`, `connman`, `net` and `rbf` had time-based "non-determinism". `addrman` is fixed in #20425. `process_message` and `process_messages` are left to fix: simply using mock time is not enough for them due to interaction with `IsInitialBlockDownload()`.

b316dcb758 [net processing] Tolerate sendheaders and sendcmpct messages before verack
BIP 130 (sendheaders) and BIP 152 (compact blocks) do not specify at
which stage the `sendheaders` or `sendcmpct` messages should be sent.
Therefore we should tolerate them being sent before the version-verack
handshake is complete.

ea36a453e3 [net] Make p2p recv buffer timeout 20 minutes for all peers
The timeout interval for the send and recv buffers was changed from 90
minutes to 20 minutes in commit f1920e86 in 2013, except for peers that
did not support the pong message (where the recv buffer timeout remained
at 90 minutes). A few observations:

- for peers that support BIP 31 (pong messages), this recv buffer
  timeout is almost redundant with the ping timeout. We send a ping
  message every two minutes, and set a timeout of twenty minutes to
  receive the pong response. If the recv buffer was really timing out,
  then the pong response would also time out.
- BIP 31 is supported by all nodes of p2p version 60000 and higher, and
  has been in widespread use since 2013. I'd be very surprised if there
  are many nodes on the network that don't support pong messages.
- The recv buffer timeout is not specified in any p2p BIP. We're free to
  set it at any value we want.
- A peer that doesn't support BIP 31 and hasn't sent any message to us
  at all in 90 minutes is unlikely to be useful for us, and is more likely
  to be evicted AttemptToEvictConnection() since it'll have the worst
  possible ping time and isn't providing blocks/transactions.

Therefore, we remove this check, and sent the recv buffer timeout to 20
minutes for all peers. This removes the final p2p version dependent
logic from the net layer, so all p2p version data can move into the
net_processing layer.

Alternative approaches:

- Set the recv buffer timeout to 90 minutes for all peers. This almost
  wouldn't be a behaviour change at all (pre-BIP 31 peers would still
  have the same recv buffer timeout, and we can't ever reach a recv buffer
  timeout higher than 21 minutes for post-BIP31 peers, because the pong
  timeout would be hit first).
- Stop supporting peers that don't support BIP 31. BIP 31 has been in
  use since 2012, and implementing it is trivial.

Merge #19763: net: don't try to relay to the address' originator
7fabe0f359 net: don't relay to the address' originator (Vasil Dimov)

Pull request description:

  For each address to be relayed we "randomly" pick 2 nodes to send the
  address to (in `RelayAddress()`). However we do not take into
  consideration that it does not make sense to relay the address back to
  its originator (`CNode::PushAddress()` will do nothing in that case).

  This means that if the originator is among the "randomly" picked nodes,
  then we will relay to one node less than intended.

  Fix this by skipping the originating node when choosing candidates to
  relay to.

94d2cc35be [net processing] Remove unnecesary nNewHeight variable in UpdatedBlockTip() (John Newbery)
8b57013473 [net processing] Remove nStartingHeight check from block relay (John Newbery)

Pull request description:

  nStartingHeight was introduced in commit 7a47324c7 (Bitcoin version
  0.2.9, P2P version 209) with the comment "better prevention of inventory
  relaying during initial download". At that time, there was no function
  to determine whether the node was still in Initial Block Download, so to
  prevent syncing nodes from relaying old blocks to their peers, a check
  was added to never relay a block to a peer where the height was lower
  than 2000 less than the peer's best block. That check was updated
  several times in later commits to ensure that we weren't relaying blocks
  before the latest checkpoint if the peer didn't provide a
  startingheight. The checkpoint comparison was changed to compare with an
  estimate of the highest block in commit eae82d8e.

  In commit 202e0194, all block relay was gated on being out of Initial
  Block Download. In commit 0278fb5f, the comparison to nBlockEstimate was
  removed since "we already checked IsIBD()".

  We can remove the check against nStartingHeight entirely. If the node is
  out of Initial Block Download, then its tip height must have been within
  24 hours of current time, so should not be more than ~144 blocks behind
  the most work tip.

  This simplifies moving block inventory state into the `Peer` object (#19829).

Pull request description:

  This PR does not change behavior when bitcoin is built normally with both the SQLite and BDB libraries. It just makes non-SQLite and non-BDB builds more similar to the normal build. Specifically:

  - It makes wallet directory lists always include all wallets so wallets don't appear missing depending on the build.

  - It now triggers specific "Build does not support SQLite database format" and "Build does not support Berkeley DB database format" errors if a wallet can't be loaded instead of the more ambiguous and scary "Data is not in recognized format" error.

  Both changes are implemented in the last commit. The previous commits are just refactoring cleanups that make the last commit possible and consolidate and reduce code.

    Tested ACK b3a515c0be over several weeks, though this change and behavior could benefit from test coverage and other follow-ups (refactoring, etc.) described in the review feedback. I did not verify the behavior of `m_start_extra_block_relay_peers` only being enabled after initial chain sync. Since my last review, one unneeded `cs_main` lock was removed.

daffaf03fb Periodically make block-relay connections and sync headers
To make eclipse attacks more difficult, regularly initiate outbound connections
and stay connected long enough to sync headers and potentially learn of new
blocks. If we learn a new block, rotate out an existing block-relay peer in
favor of the new peer.

This augments the existing outbound peer rotation that exists -- currently we
make new full-relay connections when our tip is stale, which we disconnect

net: don't relay to the address' originator
For each address to be relayed we "randomly" pick 2 nodes to send the
address to (in `RelayAddress()`). However we do not take into
consideration that it does not make sense to relay the address back to
its originator (`CNode::PushAddress()` will do nothing in that case).

This means that if the originator is among the "randomly" picked nodes,
then we will relay to one node less than intended.

Fix this by skipping the originating node when choosing candidates to
relay to.

Pull request description:

  Fixes #19676, "_For every peer expose through getpeerinfo RPC whether or not we selected them as HB peers, and whether or not they selected us as HB peers._" See [BIP152](https://github.com/bitcoin/bips/blob/master/bip-0152.mediawiki), in particular the [protocol flow diagram](https://github.com/bitcoin/bips/raw/master/bip-0152/protocol-flow.png).  The newly introduced states are changed on the following places in the code:
  * on reception of a `SENDCMPCT` message with valid version, the field `m_highbandwidth_from` is changed depending on the first integer parameter in the message (1=high bandwidth, 0=low bandwidth), i.e. it just mirrors the field `CNodeState.fPreferHeaderAndIDs`.
  * after adding a `SENDCMPCT` message to the send queue, the field `m_highbandwidth_to` is changed depending on how the first integer parameter is set (same as above)

  Note that after receiving `VERACK`, the node also sends `SENDCMPCT`, but that is only to announce the preferred version and never selects high-bandwidth mode, hence there is no need to change the state variables there, which are initialized to `false` anyways.

81137c60fe test: Add new ChainTestingSetup and use it (Carl Dong)
7e9e7fe567 qt/test: [FIX] Add forgotten Context setting in RPCNestedTests (Carl Dong)

Pull request description:

  This is part 1/n of the effort to [de-globalize `ChainstateManager`](https://github.com/bitcoin/bitcoin/pull/20158)

  Reviewers: Looking for tested/Code-Review/plain-ACKs

  ### Context

  In many of our tests, we manually instantiate `NodeContext`s or `ChainstateManager`s in the test code, which is error prone. Instead, we should create or use existing references because:
  1. Before we [de-globalize `ChainstateManager`](https://github.com/bitcoin/bitcoin/pull/20158), much of our code still acts on `g_chainman` (our global `ChainstateManager`), sometimes even when you're calling a method on a specific instance of `ChainstateManager`! This means that we may act on two instances of `ChainstateManager`, which is most likely not what we want.
  2. Using existing references (initialized by the `{Basic,}TestingSetup` constructors) means that you're acting on objects which are properly initialized, instead of "just initialized enough for this dang test to pass". Also, they're already there! It's free!
  3. By acting on the right object, we also allow the review-only assertions in future commits of [de-globalize `ChainstateManager`](https://github.com/bitcoin/bitcoin/pull/20158) to work and demonstrate correctness.

  Some more detailed debugging notes can be found in the first commit, reproduced below:
  ```
  Previously, the validation_chainstatemanager_tests test suite
  instantiated its own duplicate ChainstateManager on which tests were
  performed.

  This wasn't a problem for the specific actions performed in
  that suite. However, the existence of this duplicate ChainstateManager
  and the fact that many of our validation static functions reach for
  g_chainman, ::Chain(state|)Active means we may end up acting on two
  different CChainStates should we write more extensive tests in the
  future.

  This change adds a new ChainTestingSetup which performs all
  initialization previously done by TestingSetup except:

  1. Mempool sanity check frequency setting
  2. ChainState initialization
  3. Genesis Activation
  4. {Ban,Conn,Peer}Man initialization

  Means that we will no longer need to initialize a duplicate
  ChainstateManger in order to test the initialization codepaths of
  CChainState and ChainstateManager.

  Lastly, this change has the additional benefit of allowing for
  review-only assertions meant to show correctness to work in future work
  de-globalizing g_chainman.

  In the test chainstatemanager_rebalance_caches, an additional
  LoadGenesisBlock call is added as MaybeReblanaceCaches eventually calls
  FlushBlockFile, which tries to access vinfoBlockFile[nLastBlockFile],
  which is out of bounds when LoadGenesisBlock hasn't been called yet.

  -----

  Note for the future:

  In a previous version of this change, I put ChainTestingSetup between
  BasicTestingSetup and TestingSetup such that TestingSetup inherited from
  ChainTestingSetup.

  This was suboptimal, and showed how the class con/destructor inheritance
  structure we have for these TestingSetup classes is probably not the
  most suitable abstraction. In particular, for both TestingSetup and
  ChainTestingSetup, we need to stop the scheduler first before anything
  else. Otherwise classes depending on the scheduler may be referenced
  by the scheduler after said classes are freed. This means that there's
  no clear parallel between our teardown code and C++'s destructuring
  order for class hierarchies.

  Future work should strive to coalesce (as much as possible) test and
  non-test init codepaths and perhaps structure it in a more fail-proof
  way.

Pull request description:

  BIP155 defines addrv2 and sendaddrv2 for all protocol versions, but some implementations reject messages they don't know. As a courtesy, don't send it to nodes with a version before 70016, as no software is known to support BIP155 that doesn't announce at least that protocol version number.

  Also move the sending of sendaddrv2 earlier (before sending verack), as proposed in https://github.com/bitcoin/bips/pull/1043. This has the side effect that local address broadcast of torv3 will work (as it'll only trigger after we know whether or not the peer supports addrv2).

Pull request description:

  This just drops three interfaces::Chain methods replacing them with other calls.

  Motivation for removing these chain methods:

  - Need to get rid of findFirstBlockWithTimeAndHeight for #10102, which doesn't support overloaded methods
  - Followup from https://github.com/bitcoin/bitcoin/pull/16426#discussion_r412487403
  - phantomcircuit comments about findNextBlock test http://www.erisian.com.au/bitcoin-core-dev/log-2020-06-06.html#l-214

  Behavior is not changing in any way here. A TODO comment in ScanForWalletTransactions was removed, but just because it was invalid (see https://github.com/bitcoin/bitcoin/pull/19195#discussion_r448020762), not because it was implemented.

Merge #20561: p2p: periodically clear m_addr_known
65273fa0e7 Clear m_addr_known before our periodic self-advertisement (Suhas Daftuar)

Pull request description:

  We use a rolling bloom filter to track which addresses we've previously sent a peer, but after #7125 we no longer clear it every day before our own announcement.  This looks to me like an oversight which has the effect of reducing the frequency with which we actually self-announce our own address, so this reintroduces resetting that filter.

Pull request description:

  If the `blocksonly` mode is turned on after running with transaction
  relay enabled for a while, the fee estimation will serve outdated data
  to both the internal wallet and to external applications that might be
  feerate-sensitive and make use of `estimatesmartfee` (for example a
  Lightning Network node).

  This has already caused issues (for example https://github.com/bitcoin/bitcoin/issues/16840 (C-lightning), or https://github.com/lightningnetwork/lnd/issues/2562 (LND)) and it seems prudent to fail rather than to give inaccurate values.

  This fixes #16840, and closes #16890 which tried to fix the symptoms (RPC) but not the cause as mentioned by sdaftuar :
  > If this is a substantial problem, then I would think we should take action to protect our own wallet users as well (rather than hide the results of what our fee estimation would do!).

f3d870fc22 wallet: List all wallets in non-SQLite or non-BDB builds
This commit does not change behavior when bitcoin is built normally with both
the SQLite and BDB libraries. It just makes non-SQLite and non-BDB builds
more similar to the normal build. Specifically:

- It makes wallet directory lists always include all wallets so wallets don't
  appear missing depending on the build.

- It now triggers specific "Build does not support SQLite database format" and
  "Build does not support Berkeley DB database format" errors if a wallet can't
  be loaded instead of the more ambiguous and scary "Data is not in recognized
  format" error.

  IsSQLiteFile / ExistsSQLiteDatabase in the next commits

- Detect SQLite wallets consistently regardless whether bitcoin is built with
  SQLite support in the next commits

- Avoid attempting to open SQLite databases with the BDB library when bitcoin
  is built without SQLite support in the next commits

Merge #20530: lint, refactor: Update cppcheck linter to c++17 and improve explicit usage
1e62350ca2 refactor: Improve use of explicit keyword (Fabian Jahr)
c502a6dbfb lint: Use c++17 std in cppcheck linter (Fabian Jahr)

Pull request description:

  I found the `extended-lint-cppcheck` linter still uses `std=c++11` when reviewing #20471. The only difference in the output after this change is one line is missing:

  ```
  src/script/descriptor.cpp:159:5: warning: Struct 'PubkeyProvider' has a constructor with 1 argument that is not explicit. [noExplicitConstructor]
  ```

  After some digging, I am still not sure why this one is ignored with c++17 when 40 other`noExplicitConstructor` warnings were still appearing.

  In the second commit, I fix these warnings, adding `explicit` where appropriate and adding fixes to ignore otherwise.

Merge #18948: qt: Call setParent() in the parent's context
8963b2c71f qt: Improve comments in WalletController::getOrCreateWallet() (Hennadii Stepanov)
5fcfee68af qt: Call setParent() in the parent's context (Hennadii Stepanov)
5659e73493 qt: Add ObjectInvoke template function (Hennadii Stepanov)

Pull request description:

  The `setParent(parent)` internally calls `QCoreApplication::sendEvent(parent, QChildEvent)` that implies running in the thread which created the parent object. That is not the case always, and an internal assertion fails in the debug mode.

  Steps to reproduce this issue on master (007e15dcd7) on Linux Mint 20 (x86_64):

  ```
  $ make -C depends DEBUG=1

  $ make
