4aebd832a4 db: Change DatabaseCursor::Next to return status enum (Andrew Chow)
d79e8dcf29 wallet: Have cursor users use DatabaseCursor directly (Andrew Chow)
7a198bba0a wallet: Introduce DatabaseCursor RAII class for managing cursor (Andrew Chow)
69efbc011b Move SafeDbt out of BerkeleyBatch (Andrew Chow)
Pull request description:
Instead of having database cursors be tied to a particular `DatabaseBatch` object and requiring its setup and teardown be separate functions in that batch, we can have cursors be separate RAII classes. This makes it easier to create and destroy cursors as well as having cursors that have slightly different behaviors.
Additionally, since reading data from a cursor is a tri-state, this PR changes the return value of the `Next` function (formerly `ReadAtCursor`) to return an Enum rather than the current system of 2 booleans. This greatly simplifies and unifies the code that deals with cursors as now there is no confusion as to what the function returns when there are no records left to be read.

b358bde020 randomenv: consolidate WIN32 #ifdefs (fanquake)
fff80cd248 random: remove windows-only compat.h include in randomenv (fanquake)
Pull request description:
Similar to #26814.
Having a windows-only include of compat.h is confusing, not-only because it's already included globally via util/time.h, but also because it's unclear why compat.h is included (neither of the required headers are included there).
This change is related to removing the use of compat.h as a miscellaneous catch-all for unclear/platform specific includes. Somewhat prompted by IWYU-related discussion here: https://github.com/bitcoin/bitcoin/pull/26763/files#r1058861693.

1134686ef9 mempool: Don't share mempool with dbcache in blocksonly (willcl-ark)
Pull request description:
Fixes#9526
When `-blocksonly` has been set reduce default mempool size to avoid surprising resource usage via sharing un-used mempool cache space with dbcache.
In comparison to https://github.com/bitcoin/bitcoin/pull/9569 which either set `maxmempool` size to 0 when `-blocksonly` was set or else errored on startup, this change will permit `maxmempool` options being set.
This preserves the current (surprising?) behaviour of having a functional mempool in `-blocksonly` mode, to permit whitelisted peer transaction relay, whilst reducing average runtime memory usage for blocksonly nodes which either use the default settings or have otherwise configured a `maxmempool` size.
To use the previous old defaults node operators can configure their node with: `-blocksonly -maxmempool=300`.

In certain circumstances, we may want to flush to disk without
emptying `cacheCoins`, which affects performance. UTXO snapshot
activation is one such case.
This method is currently unused and this commit does not
change any behavior.

dee89438b8 Abstract out ComputeTapbranchHash (Russell O'Connor)
8e3fc99427 Do not use CScript for tapleaf scripts until the tapleaf version is known (Russell O'Connor)
Pull request description:
While BIP-341 calls the contents of tapleaf a "script", only in the case that the tapleaf version is `0xc0` is this script known to be a tapscript. Otherwise the tapleaf "script" is simply an uninterpreted string of bytes.
This PR corrects the issue where the type `CScript` is used prior to the tapleaf version being known to be a tapscript. This prevents `CScript` methods from erroneously being called on non-tapscript data.
A second commit abstracts out the TapBranch hash computation in the same manner that the TapLeaf computation is already abstracted. These two abstractions ensure that the TapLeaf and TapBranch tagged hashes are always constructed properly.

b68e5a7fef lint: specify the right commit range when running locally (James O'Beirne)
dff7ed5732 test: add an easy way to run linters locally (James O'Beirne)
Pull request description:
Adds a Dockerfile configuration ~~(originally written mostly by fanquake)~~ that allows straightforward running of linters with compatible versions locally. This removes a ton of annoyance when trying to appease CI, because many of the linter versions are quite old and difficult to maintain locally.
I realize that people may not be thrilled to add more ancillary tooling to the repo, but I think this makes a lot of sense given the linter versions listed in this container configuration are dictated by this repo (within the CI configuration), so having these things live in two separate places is a recipe for version mismatches.
Eventually we can likely just use this container on CI directly to avoid any chance of inconsistencies between local dev experience and CI.

5eabb61b23 addrdb: Only call Serialize() once (Martin Zumsande)
da6c7aeca3 hash: add HashedSourceWriter (Martin Zumsande)
Pull request description:
There have been various reports of corruption of `peers.dat` recently, see #26599.
As explained in [this post](https://github.com/bitcoin/bitcoin/issues/26599#issuecomment-1381082886) in more detail, the underlying issue is likely that we currently serialize `AddrMan` twice - once for the file stream, once for the hasher that helps create the checksum - and if `AddrMan` changes in between these two calls, the checksum doesn't match the data and the resulting `peers.dat` is corrupted.
This PR attempts to fix this by introducing and using `HashedSourceWriter` - a class that keeps a running hash while serializing data, similar to the existing `CHashVerifier` which does the analogous thing while unserializing data. Something like this was suggested before, see https://github.com/bitcoin/bitcoin/pull/10248#discussion_r120694343.
Fixes#26599 (not by changing the behavior in case of a crash, but by hopefully fixing the underlying cause of these corruptions).

d96d97ad30 doc: Add release note for shutdownnotify. (klementtan)
0bd73e2c45 util: Add -shutdownnotify option. (klementtan)
Pull request description:
**Description**: Similar to `-startupnotify`, this PR adds a new option to allow users to specify a command to be executed when Bitcoin Core shuts down.
**Note**: The `shutdownnotify` commands will not be executed if bitcoind shut down due to *unexpected* reasons (ie `killall -9 bitcoind`).
### Testing:
**Normal shutdown commands**
```
# start bitcoind with shutdownnotify optioin
./src/bitcoind -signet -shutdownnotify="touch foo.txt"
# shutdown bitcoind
./src/bitcoin-cli -signet stop
# check that foo.txt has been created
```
**Final RPC call**
Commands:
```
$ ./src/bitcoind -signet -nolisten -noconnect -shutdownnotify="./src/bitcoin-cli -signet getblockchaininfo > tmp.txt"
$ ./src/bitcoin-cli stop
$ cat tmp.txt
```
