d83bea42d1f0ffb0899a6de3556c489543468995 wallettool: Don't create CWallet when dumping DB (Andrew Chow)
40c80e36b1a204ed133acc403016a6cb1a92051e wallettool: Don't unilaterally reset wallet_instance if loading error (Ava Chow)
Pull request description:
https://github.com/bitcoin/bitcoin/issues/29109#issuecomment-1863449058 reports that a wallet with noncritical errors cannot be dumped with `bitcoin-wallet dump`. This was caused by an erroneous reset of the wallet pointer when the loading the wallet returns something other than `LOAD_OK`. Not all errors are errors that require aborting, so unilaterally resetting the pointer at that time is incorrect. The first commit resolves this issue.
Furthermore, if a wallet has loading errors, that should not prevent the wallet tool from dumping the wallet. The wallet application logic should not get in the way of performing such a low level database operation, especially when it's primary usage is for debugging potentially corrupted wallets. The 2nd commit is taken from #28710 and changes the `dump` to stop at making a `WalletDatabase` rather than making a `CWallet` only to retrieve the underlying `WalletDatabase`.

fa46cc22bc696e6845915ae91d6b68e36bf4c242 Remove deprecated -rpcserialversion (MarcoFalke)
Pull request description:
The flag is problematic for many reasons:
* It is deprecated
* It is a global flag, requiring a restart to change, as opposed to a flag that can be set on each RPC invocation
* It may be hidden in config files by accident, hard to debug, causing LND crashes and bugs, see https://github.com/bitcoin/bitcoin/issues/28730#issuecomment-1780940868
* It makes performance improvements harder to implement: https://github.com/bitcoin/bitcoin/pull/17529#issuecomment-556082818
Fix all issues by removing it.
If there is a use-case, likely a per-RPC flag can be added, if needed.

Pull request description:
This includes changes from the 0.4.1 release: https://github.com/bitcoin-core/secp256k1/releases/tag/v0.4.1.
> The point multiplication algorithm used for ECDH operations (module ecdh) was replaced with a slightly faster one.
> Optional handwritten x86_64 assembly for field operations was removed because modern C compilers are able to output more efficient assembly. This change results in a significant speedup of some library functions when handwritten x86_64 assembly is enabled (--with-asm=x86_64 in GNU Autotools, -DSECP256K1_ASM=x86_64 in CMake), which is the default on x86_64. Benchmarks with GCC 10.5.0 show a 10% speedup for secp256k1_ecdsa_verify and secp256k1_schnorrsig_verify.

Pull request description:
This is a simple PR that does two things
1. Fixes#29000 by waiting for the fee estimator to catch up after `removeForBlock` calls before calling `estimateFee` in the `BlockPolicyEstimates` unit test.
2. Addressed some outstanding review comments from #28368
- Updated `NewMempoolTransactionInfo::m_from_disconnected_block` to `NewMempoolTransactionInfo::m_mempool_limit_bypassed` which now correctly indicates what the boolean does.
- Changed input of `processTransaction`'s tx_info `m_submitted_in_package` input from false to fuzz data provider boolean.
- Fixed some typos, and update incorrect comment

In reality some mempool transaction might be submitted in a package,
so change m_submitted_in_package to fuzz data provider boolean just like
m_has_no_mempool_parents.
The boolean indicates whether the transaction was added without enforcing mempool
fee limits. m_mempool_limit_bypassed is the correct variable name.
Also changes NewMempoolTransactionInfo booleans descriptions to the format that
is consistent with the codebase.
Making the `GenerateRandomKey` helper available to other modules via
key.{h.cpp} allows us to create random private keys directly at
instantiation of CKey, in contrast to the two-step process of creating
the instance and then having to call `MakeNewKey(...)`.

This is fine. However, it would be more helpful for developers and more accurate by the compiler to explain why each function is not selected.
Fix this by using C++20 concepts where appropriate.

It's not necessary to set up an entire CWallet just so we can get access
to the WalletDatabase and read the records. Instead we can go one level
lower and make just a WalletDatabase.
When there is a wallet loading error, it could be a noncritical one so
it is not necessary to make wallet_instance a nullptr. The wallet can
still go on with normal operation in that case, as we do for loading in
bitcoind and bitcoin-qt.
8dec9c560b53488c1e71d8f74241c7dce42cb387 wallet, mempool: propagete `checkChainLimits` error message to wallet (ismaelsadeeq)
Pull request description:
* Requested in [#28391 comment](https://github.com/bitcoin/bitcoin/pull/28391#discussion_r1382997719)
* The error message is static when a new transaction is created and package limit is reached.
`Transaction has too long of a mempool chain`
While the [`CTxMempool::CheckPackageLimits`](5800c558eb/src/txmempool.cpp (L199)) provide explicit information about the error message.
* This PR updates [`CTxMempool::CheckPackageLimits`](5800c558eb/src/txmempool.cpp (L199)) return type to `util::Result<void>`, `CheckPackageLimits` now returns void when package limit is not hit, and returns the error string whenever package limit is hit instead of using out parameter `errString`.
* The PR updates [`checkChainLimits`](5800c558eb/src/node/interfaces.cpp (L703)) return type to `util::Result<void>`.
* Now the wallet `CreateTransactionInternal` will have access to the package limit error string whenever its hit.
* Also Updated functional test to reflect the error message from `CTxMempool::CheckPackageLimits` output.

Pull request description:
This change drops `shutdown.h` and `shutdown.cpp` files, replacing them with a `NodeContext::shutdown` member which is used to trigger shutdowns directly. This gets rid of an unnecessary layer of indirection, and allows getting rid of the `kernel::g_context` global.
Additionally, this PR tries to improve error handling of `SignalInterrupt` code by marking relevant methods `[[nodiscard]]` to avoid the possibility of uncaught exceptions mentioned https://github.com/bitcoin/bitcoin/pull/27861#discussion_r1255496707.
Behavior is changing In a few cases which are noted in individual commit messages. Particularly: GUI code more consistently interrupts RPCs when it is shutting down, shutdown state no longer persists between unit tests, the stop RPC now returns an RPC error if requesting shutdown fails instead of aborting, and other failed shutdown calls now log errors instead of aborting.
This PR is a net reduction in lines of code, but in some cases the explicit error handling and lack of global shutdown functions do make it more verbose. The verbosity can be seen as good thing if it discourages more code from directly triggering shutdowns, and instead encourages code to return errors or send notifications that could be translated into shutdowns. Probably a number of existing shutdown calls could just be replaced by better error handling.

Pull request description:
Fixes#29061. Only the benchmark is affected.
Since #25273, the behavior of 'inserting change at a random position'
is instructed by passing ´std::nullopt´ instead of -1.
Also, added missing documentation about the meaning of
'change_pos=std::nullopt' inside 'CWallet::CreateTransaction()'

Pull request description:
`GetUniquePath` is only used in tests and in `DirIsWritable`. The check by `DirIsWritable` is redundant with the check done in `LockDirectory`.
Fix the redundancy by removing everything, except `LockDirectory`.

Pull request description:
Solves #28918. Coming from https://github.com/bitcoin/bitcoin/issues/28918#issuecomment-1838626406 discussion.
The intention is to decouple only the bugfix relevant commits from #28985, allowing them to be included in the 26.x release. This way, we can avoid disabling the coin selection fuzzing test for an entire release.
Note:
Have introduced few changes to the bug fix commit so that the unit tests pass without the additional burden introduced in #28985.

fb0b6ca4e5d981cf58bf23ae2993117f171608e8 tests, bench: Remove incorrect LoadWallet() calls (Andrew Chow)
Pull request description:
`CWallet::LoadWallet()` expects to be called after a `CWallet` is constructed, but before any of its member functions called. Doing so invalidates pointers which causes issues with some PRs and branches that I am working on. This was being used incorrectly in a few tests and benchmarks, resulting in segfaults.
As a precaution for this kind of issue in the future, I've also added a few asserts to `LoadWallet()` so that developers will notice when it is used incorrectly.
As similar issue was fixed in #27666

Verify the transaction creation process does not produce
a BnB solution when SFFO is enabled.
This is currently problematic because it could require a
change output. And BnB is specialized on changeless solutions.
