Merge #19370: Static asserts for consistency of fee defaults
1554b54d47 Static asserts for consistency of fee defaults. (Daniel Kraft)

Pull request description:

  This adds `static_assert`'s that ensure that the default values given for fee levels in the wallet (minimum fee and incremental feerate increase) are at least as high as the corresponding levels configured in the core node policy.  Since the core policy values are enforced by the network, it makes sense for the wallet to be conservative and above (or at least not below) this.

fa6ef701ad util: Add Assert identity function (MarcoFalke)
fa457fbd33 move-only: Move NDEBUG compile time check to util/check (MarcoFalke)

Pull request description:

  The utility function is primarily useful to dereference pointer types, which are known to be not null at that time.

  For example, the ArgsManager is known to exist when the wallets are started: https://github.com/bitcoin/bitcoin/pull/18923/files#diff-fdb2a1a1d8bc790fcddeb6cf5a42ac55R503 . Instead of silently relying on that assumption, `Assert` can be used to abort the program and avoid UB should the assumption ever be violated.

Merge #19413: refactor: Remove confusing BlockIndex global
fa0dfdf447 refactor: Remove confusing BlockIndex global (MarcoFalke)

Pull request description:

  The global `::BlockIndex()` is problematic for several reasons:

  * It returns a mutable reference to the block tree, without the appropriate lock annotation (`m_block_index` is guarded by `cs_main`). The current code is fine, but in the future this might lead to accidental races and data corruption.
  * The rpc server shouldn't rely on node globals, but rather a context that is passed in to the RPC method.
  * Tests might want to spin up their own block tree, and thus should also not rely on a single global.

  Fix all issues by removing the global

Merge #9381: Remove CWalletTx merging logic from AddToWallet
28b112e9bd Get rid of BindWallet (Russell Yanofsky)
d002f9d15d Disable CWalletTx copy constructor (Russell Yanofsky)

bd2fbc7cdb Get rid of unneeded CWalletTx::Init parameter (Russell Yanofsky)
2b9cba2065 Remove CWalletTx merging logic from AddToWallet (Russell Yanofsky)

Pull request description:

  This is a pure refactoring, no behavior is changing.

  Instead of AddToWallet taking a temporary CWalletTx object and then potentially merging it with a pre-existing CWalletTx, have it take a callback so callers can update the pre-existing CWalletTx directly.

  This makes AddToWallet simpler because now it is only has to be concerned with saving CWalletTx objects and not merging them.

  This makes AddToWallet calls clearer because they can now make direct updates to CWalletTx entries without having to make temporary objects and then worry about how they will be merged.

  Motivation for this change came from the bumpfee PR #8456 where we wanted to be able to call AddToWallet to make a simple update to an existing transaction, but were reluctant to, because the existing CWalletTx merging logic did not apply and seemed dangerous try to update as part of that PR. After this refactoring, the bumpfee PR could call AddToWallet safely instead of implementing a duplicate AddToWallet function.

  This also allows getting rid of the CWalletTx copy constructor to prevent unintentional copying.

6a72f26968 [wallet] Remove locked_chain from CWallet, its RPCs and tests
This change is intended to make the bitcoin node and its rpc, network
and gui interfaces more responsive while the wallet is in use. Currently
because the node's cs_main mutex is always locked before the wallet's
cs_wallet mutex (to prevent deadlocks), cs_main currently stays locked
while the wallet does relatively slow things like creating and listing
transactions.

This commit only remmove chain lock tacking in wallet code, and invert
lock order from cs_main, cs_wallet to cs_wallet, cs_main.
must happen at once to avoid any deadlock. Previous commit were only
removing Chain::Lock methods to Chain interface and enforcing they
take cs_main.

Remove LockChain method from CWallet and Chain::Lock interface.

7918c1b019 test: Add CreateWalletFromFile test
Add unit test calling CreateWalletFromFile, which isn't currently called from
other unit tests, with some basic checks to make sure it rescans and registers
for notifications correctly.

Motivation for this change was to try to write a test that would fail without
the early `handleNotifications` call in ef8c6ca60767cac589d98ca57ee33179608ccda8
from https://github.com/bitcoin/bitcoin/pull/16426, but succeed with it:

ef8c6ca607/src/wallet/wallet.cpp (L3978-L3986)

However, writing a full test for the race condition that call prevents isn't
possible without the locking changes from #16426. So this PR just adds as much
test coverage as is possible now.

This new test is also useful for https://github.com/bitcoin/bitcoin/pull/15719,
since it detects the stale notifications.transactionAddedToMempool notifications
that PR eliminates.

Merge #18671: wallet: Add BlockUntilSyncedToCurrentChain to dumpwallet
fa60afc4fb wallet: Add BlockUntilSyncedToCurrentChain to dumpwallet (MarcoFalke)

Pull request description:

  dumpwallet includes the block hash in the output, so this method depends on the chainstate. According to the developer notes e84a5f0004/doc/developer-notes.md (L1095) it must include a `BlockUntilSyncedToCurrentChain`.

  This is a minor fix and does not need backport, I think.

  It fixes test failures such as https://travis-ci.org/github/bitcoin/bitcoin/jobs/675487097#L2657 , which can only happen in master because the test was not backported.

Pull request description:

  When writing tests, often includes need to be added or removed. Currently the list of includes is not sorted, so developers that write tests and have `clang-format` installed will either have an unrelated change (sorting) included in their commit or they will have to manually undo the sort.

  This pull preempts both issues by just sorting all includes in one commit.

  Please be aware that this is **NOT** a change to policy to enforce clang-format or any other developer guideline or process. Developers are free to use whatever tool they want, see also #18651.

  Edit: Also includes a commit to bump the copyright headers, so that the touched files don't need to be touched again for that.

Pull request description:

  This is part of the [assumeutxo project](https://github.com/bitcoin/bitcoin/projects/11):

  Parent PR: #15606
  Issue: #15605
  Specification: https://github.com/jamesob/assumeutxo-docs/tree/master/proposal

  ---

  This changeset introduces `ChainstateManager`, which is responsible for creating and managing access to multiple chainstates. Until we allow chainstate creation from UTXO snapshots (next assumeutxo PR?) it's basically unnecessary, but it is a prerequisite for background IBD support.

  Changes are also made to the initialization process to make use of `g_chainman` and thus clear the way for multiple chainstates being loaded on startup.

  One immediate benefit of this change is that we no longer have the `g_blockman` global, but instead have the ChainstateManager inject a reference of its shared BlockManager into any chainstate it creates.

  Another immediate benefit is that uses of `ChainActive()` and `ChainstateActive()` are now covered by lock annotations. Because use of `g_chainman` is annotated to require cs_main, these two functions subsequently follow.

  Because of whitespace changes, this diff looks bigger than it is. E.g., 4813167d98 is most easily reviewed with
  ```sh
  git show --color-moved=dimmed_zebra -w 4813167d98
  ```

c0d07dc4cb wallet: Avoid use of Chain::Lock in CWallet::ScanForWalletTransactions
This is a step toward removing the Chain::Lock class and reducing cs_main
locking.

This change affects behavior in a few small ways.

- If there's no max_height specified, percentage progress is measured ending at
  wallet last processed block instead of node tip

- More consistent error reporting: Early check to see if start_block is on the
  active chain is removed, so start_block is always read and the triggers an
  error if it's unavailable

bc96a9bfc6 wallet: Avoid use of Chain::Lock in importmulti
This is a step toward removing the Chain::Lock class and reducing cs_main
locking.

This change only affects behavior in the case where wallet last block processed
falls behind the chain tip, in which case it may use a more accurate rescan
time.

25a9fcf9e5 wallet: Avoid use of Chain::Lock in importwallet and dumpwallet
This is a step toward removing the Chain::Lock class and reducing cs_main
locking.

This change only affects behavior in the case where wallet last block processed
falls behind the chain tip, in which case it will use more accurate backup and
rescan timestamps.

ab31b9d6fe Fix wallet unload race condition
Currently it's possible for ReleaseWallet to delete the CWallet pointer while
it is processing BlockConnected, etc chain notifications.

To fix this, unregister from notifications earlier in UnloadWallet instead of
ReleaseWallet, and use a new RegisterSharedValidationInterface function to
prevent the CValidationInterface shared_ptr from being deleted until the last
notification is actually finished.

c9017ce3bc protect g_chainman with cs_main
I'd previously attempted to create a specialized lock for ChainstateManager,
but it turns out that because that lock would be required for functions like
ChainActive() and ChainstateActive(), it created irreconcilable lock inversions
since those functions are used so broadly throughout the codebase.

Instead, I'm just using cs_main to protect the contents of g_chainman.

82a30fade7 Move key and script filling and signing from CWallet::FillPSBT to ScriptPubKeyMan::FillPSBT
Instead of fetching a SigningProvider from ScriptPubKeyMan in order
to fill and sign the keys and scripts for a PSBT, just pass that
PSBT to a new FillPSBT function that does all that for us.

9b5950db86 bnb: exit selection when best_waste is 0
If we find a solution which has no waste, just use that. This solution
is what we would consider to be optimal, and other solutions we find
would have to also have 0 waste, so they are equivalent to the first
one with 0 waste. Thus we can optimize by just choosing the first one
with 0 waste.

005f8a92cc wallet: Improve LegacyScriptPubKeyMan::CanProvide script recognition
Make LegacyScriptPubKeyMan::CanProvide method able to recognize p2sh scripts
when the redeem script is present in the mapScripts map without the p2sh script
also having to be added to the mapScripts map. This restores behavior prior to
https://github.com/bitcoin/bitcoin/pull/17261, which I think broke backwards
compatibility with old wallet files by no longer treating addresses created by
`addmultisigaddress` calls before #17261 as solvable.

The reason why tests didn't fail with the CanProvide implementation in #17261
is because of a workaround added in 4a7e43e846
"Store p2sh scripts in AddAndGetDestinationForScript", which masked the problem
for new `addmultisigaddress` RPC calls without fixing it for multisig addresses
already created in old wallet files.

This change adds a lot of comments and allows reverting commit
4a7e43e846 "Store p2sh scripts in
AddAndGetDestinationForScript", so the AddAndGetDestinationForScript() function,
CanProvide() method, and mapScripts map should all be more comprehensible
