so we erase all the records atomically or abort the entire
procedure.
and, at the same time, we can share the same db txn context
for the db cursor and the erase functionality.
extra note from the Db.cursor doc:
"If transaction protection is enabled, cursors must be
opened and closed within the context of a transaction"
thus why added a `CloseCursor` call before calling to
`TxnAbort/TxnCommit`.
If the batch ptr is not passed, the cursor will not use the db active
txn context which could lead to a deadlock if the code tries to modify
the db while it is traversing it.
E.g. the 'EraseRecords()' function.

33c6245ac1 Introduce MockableDatabase for wallet unit tests (Andrew Chow)
Pull request description:
For the wallet's unit tests, we currently use either `DummyDatabase` or memory-only versions of either BDB or SQLite. The tests that use `DummyDatabase` just need a `WalletDatabase` so that the `CWallet` can be constructed, while the tests using the memory-only databases just need a backing data store. There is also a `FailDatabase` that is similar to `DummyDatabase` except it fails be default or can have a configured return value. Having all of these different database types can make it difficult to write tests, particularly tests that work when either BDB or SQLite is disabled.
This PR unifies all of these different unit test database classes into a single `MockableDatabase`. Like `DummyDatabase`, most functions do nothing and just return true. Like `FailDatabase`, the return value of some functions can be configured on the fly to test various failure cases. Like the memory-only databases, records can actually be written to the `MockableDatabase` and be retrieved later, but all of this is still held in memory. Using `MockableDatabase` completely removes the need for having BDB or SQLite backed wallets in the unit tests for the tests that are not actually testing specific database behaviors.
Because `MockableDatabase`s can be created by each unit test, we can also control what records are stored in the database. Records can be added and removed externally from the typical database modification functions. This will give us greater ability to test failure conditions, particularly those involving corrupted records.

The libbitcoin_kernel library should not rely on the `ArgsManager`, but rather use option structs that can be passed to the various classes it uses. This PR removes reliance on the `ArgsManager` from the `blockstorage.*` files. Like similar prior work, it uses the options struct in the `BlockManager` that can be populated with `ArgsManager` values.

72efc26439 util: improve streams.h:FindByte() performance (Larry Ruane)
604df63f6c [bench] add streams findbyte (gzhao408)
Pull request description:
This PR is strictly a performance improvement; there is no functional change. The `CBufferedFile::FindByte()` method searches for the next occurrence of the given byte in the file. Currently, this is done by explicitly inspecting each byte in turn. This PR takes advantage of `std::find()` to do the same more efficiently, improving its CPU runtime by a factor of about 25 in typical use.

Add a stop_after_block_import field to the BlockManager options. Use
this field instead of the global gArgs.
This should allow users of the BlockManager to not rely on the global
Args.
Add a blocks_dir field to the BlockManager options. Move functions
relying on the global gArgs to get the blocks_dir into the BlockManager
class.
This should eventually allow users of the BlockManager to not rely on
the global Args and instead pass in their own options.
Remove access to the global gArgs for the fastprune argument and
replace it by adding a field to the existing BlockManager Options
struct.
When running `clang-tidy-diff` on this commit, there is a diagnostic
error: `unknown type name 'uint64_t' [clang-diagnostic-error] uint64_t
prune_target{0};`, which is fixed by including cstdint.
This should eventually allow users of the BlockManager to not rely on
the global gArgs and instead pass in their own options.
This is a commit in preparation for the next few commits. The functions
are moved to methods to avoid their re-declaration for the purpose of
passing in BlockManager options.
The functions that were now moved into the BlockManager should no longer
use the params as an argument, but instead use the member variable.
In the moved ReadBlockFromDisk and UndoReadFromDisk, change
the function signature to accept a reference to a CBlockIndex instead of
a raw pointer. The pointer is expected to be non-null, so reflect that
in the type.
To allow for the move of functions to BlockManager methods all call
sites require an instantiated BlockManager, or a callback to one.
The lambda captures a reference to the chainman unique_ptr to retrieve
block data. An assert is added on the chainman to ensure that the lambda
is not used while the chainman is uninitialized.
This is done in preparation for the following commits where blockstorage
functions are made BlockManager methods.

Ensures better memory safety for this global. This came up during
discussion of the following commit, but is not strictly required for its
implementation.
If transactions are being added to the mempool at a rate faster than 7tx/s
(INVENTORY_BROADCAST_PER_SECOND) then peers' inventory_to_send queue can
become relatively large. If this happens, increase the number of txids
we include in an INV message (normally capped at 35) by 5 for each 1000
txids in the queue.
This will tend to clear a temporary excess out reasonably quickly; an
excess of 4000 invs to send will be cleared down to 1000 in about 30
minutes, while an excess of 20000 invs would be cleared down to 1000 in
about 60 minutes.
We use CompareDepthAndScore to choose an order of txs to inv. Rather
than sorting txs that have been evicted from the mempool at the end
of the list, sort them at the beginning so they are removed from
the queue immediately.

This pull request is part of the `libbitcoinkernel` project https://github.com/bitcoin/bitcoin/issues/24303https://github.com/bitcoin/bitcoin/projects/18 and more specifically its "Step 2: Decouple most non-consensus code from libbitcoinkernel". It is also a follow up to #26177.
It replaces pull request https://github.com/bitcoin/bitcoin/pull/27294, which just moved the constants to a new file, but did not re-declare them as enums.
The code move of the chain name constants out of the `chainparamsbase` to their own separate header allows the kernel `chainparams` to no longer include `chainparamsbase`. The `chainparamsbase` contain references to the `ArgsManager` and networking related options that should not belong to the kernel library. Besides this move, the constants are re-declared as enums with helper functions facilitating string conversions.

This is a follow-up to previous commits moving the chain constants out
of chainparamsbase.
The script removes the chainparamsbase header in all files where it is
included, but not used. This is done by filtering against all defined
symbols of the header as well as its respective .cpp file.
The kernel chainparams now no longer relies on chainparamsbase.

-END VERIFY SCRIPT-
This commit effectively moves the definition of these constants
out of the chainparamsbase to their own file.
Using the ChainType enums provides better type safety compared to
passing around strings.
The commit is part of an ongoing effort to decouple the libbitcoinkernel
library from the ArgsManager and other functionality that should not be
part of the kernel library.
These are introduced for the next commit where the usage of the
ChainType is adopted throughout the code.

bd13dc2f46 Switch hardened derivation marker to h in descriptors (Sjors Provoost)
Pull request description:
This makes it easier to handle descriptor strings manually, especially when importing from another Bitcoin Core wallet.
For example the `importdescriptors` RPC call is easiest to use `h` as the marker: `'["desc": ".../0h/..."]'`, avoiding the need for escape characters. With this change `listdescriptors` will use `h`, so you can copy-paste the result, without having to add escape characters or switch `'` to 'h' manually.
Both markers can still be parsed.
The `hdkeypath` field in `getaddressinfo` is also impacted by this change, except for legacy wallets. The latter is to prevent accidentally breaking ancient software that uses our legacy wallet.

c4981e7f63 prune, import: fixes #23852 (mruddy)
Pull request description:
Fixes #23852
This allows pruning to work during the `-loadblock` import process.
An example use case is where you have a clean set of block files and you want to create a pruned node from them, but you don't want to alter the input set of block files.
#23852 noted that pruning was not working reliably during the loadblock import process. The reason why the loadblock process was not pruning regularly as it progressed is that the pruning process (`BlockManager::FindFilesToPrune`) checks the tip height of the active chainstate, and `CChainState::ActivateBestChain` was not called (which updates that tip height) in `ThreadImport` until after all the import files were processed.
An example bash command line that makes it easy to import a bunch of block files:
```
./src/qt/bitcoin-qt -debug -logthreadnames -datadir=/tmp/btc -prune=550 -loadblock=/readonly/btc/main/blk{00000..00043}.dat
```
One interesting side note is that `CChainState::ActivateBestChain` can be called while the import process is running (in the `loadblk` thread) by concurrent network message processing activity in the `msghand` thread. For example, one way to reproduce this easily is with the `getblockfrompeer` RPC (requesting a block with height greater than 100000) run from a node connected to an importing node. There are other ways too, but this is an easy way. I only mention this to explain how the `max_prune_height=225719` log message in the original issue came to occur.

In the wallet ckey loading test, we modify various ckey records to test
corruption handling. As the database is now a mockable database, we can
modify the records that the database will be initialized with. This
avoids having to use the verbose database reading and writing functions.
