fReindex is one of the last remaining globals exposed by the kernel
library, so move it into the blockstorage class to reduce the amount of
global mutable state and make the kernel library a bit less awkward to
use.

The key module's functionality is not used by the kernel library, but
currently kernel users are still required to initialize the key module's
`secp256k1_context_sign` global as part of the `kernel::Context` through
`ECC_Start`.

b9f04be870c948f071216fba8402a2c5395a336b mempool: Log added for dumping mempool transactions to disk (kevkevin)
Pull request description:
Sometimes when shutting off bitcoind it can take a while to dump the mempool transaction onto the disk so
this change adds additional logging to the `DumpMempool` method in `kernel/mempool_persist.cpp`
Motivated by https://github.com/bitcoin/bitcoin/pull/29227 this change
- adds a single new line for the amount of transactions being dumped and the amount of memory being dumped to file
This is in response to https://github.com/bitcoin/bitcoin/pull/29227#issuecomment-1893375082

The extra `bilingual_str` argument of the fatal error notifications and
`node::AbortNode()` is often unused and when used usually contains the
same string as the message argument. It also seems to be confusing,
since it is not consistently used for errors requiring user action. For
example some assumeutxo fatal errors require the user to do something,
but are not translated.
So simplify the fatal error and abort node interfaces by only passing a
translated string. This slightly changes the fatal errors displayed to
the user.
Also de-duplicate the abort error log since it is repeated in noui.cpp.

3fba3d5deec6d7bae33823b8da7682f9b03d9deb [refactor] Make signals optional in mempool and chainman (TheCharlatan)
Pull request description:
By defining a virtual interface class for the scheduler client, users of the kernel can now define their own event consuming infrastructure, without having to spawn threads or rely on the scheduler design.
Removing `CScheduler` also allows removing the thread and exception modules from the kernel library.
To make the `CMainSignals` class easier to use from a kernel library perspective, remove its global instantiation and adopt RAII practices.
Renames `CMainSignals` to `ValidationSignals`, which more accurately describes its purpose and scope.
Also make the `ValidationSignals` in the `ChainstateManager` and CTxMemPool` optional. This could be useful in the future for using or testing these classes without having to instantiate any form of signal handling.
---
This PR is part of the [libbitcoinkernel project](https://github.com/bitcoin/bitcoin/issues/27587). It improves the kernel API and removes two modules from the kernel library.

This is done in preparation for the next two commits, where the
CMainSignals are de-globalized.
This avoids adding new constructor arguments to the ChainstateManager
and CTxMemPool classes over the next two commits.
This could also allow future tests that are only interested in the
internal behaviour of the classes to forgo instantiating the signals.

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

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.
|
|
This change is mostly a refectoring that removes some code and gets rid of an
unnecessary layer of indirection after #27861
But it is not a pure refactoring since StartShutdown, AbortShutdown, and
WaitForShutdown functions used to abort on failure, and the replacement code
logs or returns errors instead.

Pull request description:
This is an attempt to #11775
This Pr will enable fee estimator to listen to ValidationInterface notifications to process new transactions added and removed from the mempool.
This PR includes the following changes:
- Added a new callback to the Validation Interface `MempoolTransactionsRemovedForConnectedBlock`, which notifies listeners about the transactions that have been removed due to a new block being connected, along with the height at which the transactions were removed.
- Modified the `TransactionAddedToMempool` callback parameter to include additional information about the transaction needed for fee estimation.
- Updated `CBlockPolicyEstimator` to process transactions using` CTransactionRef` instead of `CTxMempoolEntry.`
- Implemented the `CValidationInterface` interface in `CBlockPolicyEstimater` and overridden the `TransactionAddedToMempool`, `TransactionRemovedFromMempool`, and `MempoolTransactionsRemovedForConnectedBlock` methods to receive updates from their notifications.
Prior to this PR, the fee estimator updates from the mempool, i.e whenever a new block is connected all transactions in the block that are in our mempool are going to be removed using the `removeForBlock` function in `txmempool.cpp`.
This removal triggered updates to the fee estimator. As a result, the fee estimator would block mempool's `cs` until it finished updating every time a new block was connected.
Instead of being blocked only on mempool tx removal, we were blocking on both tx removal and fee estimator updating.
If we want to further improve fee estimation, or add heavy-calulation steps to it, it is currently not viable as we would be slowing down block relay in the process
This PR is smaller in terms of the changes made compared to #11775, as it focuses solely on enabling fee estimator updates from the validationInterface/cscheduler thread notifications.
I have not split the validation interface because, as I understand it, the rationale behind the split in #11775 was to have `MempoolInterface` signals come from the mempool and `CValidationInterface` events come from validation. I believe this separation can be achieved in a separate refactoring PR when the need arises.
Also left out some commits from #11775
- Some refactoring which are no longer needed.
- Handle reorgs much better in fee estimator.
- Track witness hash malleation in fee estimator
I believe they are a separate change that can come in a follow-up after this.

Pull request description:
This has the goal of prohibiting users from accidentally creating runtime failures, e.g. by interacting with iterator_to with a copied entry. This was brought up here: https://github.com/bitcoin/bitcoin/pull/28886#issuecomment-1814794954.
CTxMemPoolEntry is already implicitly not move-constructable. So be explicit about this and use a std::list to collect the values in the policy_estimator fuzz test instead of a std::vector.

I changed my DNS seeds to .net from .org to avoid issues with DNS blacklisting,
that falsely thinks my domain name is pointing to IP addresses with malware and
similar things. Right now there are CNAME records, so the .org addresses still
work. But eventually, if needed, I'll remove those CNAME's.

`CBlockPolicyEstimator` will implement `CValidationInterface` and
subscribe to its notification to process transactions added and removed
from the mempool.
Re-delegate calculation of `validForFeeEstimation` from validation to fee estimator.
Also clean up the validForFeeEstimation arg thats no longer needed in `CTxMempool`.

Create a new struct `NewMempoolTransactionInfo` that will be used as the new parameter of
`TransactionAddedToMempool` callback.
|
|
This commit adds a new callback `MempoolTransactionsRemovedForBlock` which notify
its listeners of the transactions that are removed from the mempool because a new
block is connected, along with the block height the transactions were removed.
The transactions are in `RemovedMempoolTransactionInfo` format.
`CTransactionRef`, base fee, virtual size, and height which the transaction was added
to the mempool are all members of the struct called `RemovedMempoolTransactionInfo`.
A struct `NewMempoolTransactionInfo`, which has fields similar to `RemovedMempoolTransactionInfo`,
will be added in a later commit, create a struct `TransactionInfo` with all similar fields.
They can both have a member with type `TransactionInfo`.

This has the goal of prohibiting users from accidentally creating
runtime failures, e.g. by interacting with iterator_to with a copied
entry.
CTxMemPoolEntry is already implicitly not move-constructable. So be
explicit about this and use a std::list to collect the values in the
policy_estimator fuzz test instead of a std::vector.

fa6b053b5c964fb35935fa994cb782c0731a56f8 mempool: persist with XOR (MarcoFalke)
Pull request description:
Currently the `mempool.dat` file stores data received from remote peers as-is. This may be problematic when a program other than Bitcoin Core tries to interpret them by accident. For example, an anti-virus program or other program may scan the file and move it into quarantine, or delete it, or corrupt it.
While the local wallet is expected to re-submit any pending transactions, unrelated transactions may be missing from the mempool after a restart. This may cause fee estimates to be off, or may cause block relay to be slower.
Fix this, similar to https://github.com/bitcoin/bitcoin/pull/6650, by rolling a random XOR pattern over the dat file when writing or reading it.
Obviously this can only protect against programs that accidentally and unintentionally are trying to mess with the dat file. Any program that intentionally wants to mess with the dat file can still trivially do so.

Allows calling UpdateLockPoints() with a (const) txiter. Note that this
was already possible for caller using mapTx.modify(txiter). The point
here is to not be accessing mapTx when doing so.
|
|
Instead of reaching into the mapTx data structure, use a helper method
that provides the required vector of CTxMemPoolEntry pointers.

Pull request description:
This PR is a follow-up to fix review comments and a bugfix from #28385
The PR
- Updated `DisconnectedBlockTransactions`'s `MAX_DISCONNECTED_TX_POOL` from kb to bytes.
- Moved `DisconnectedBlockTransactions` implementation code to `kernel/disconnected_transactions.cpp`.
- `AddTransactionsFromBlock` now assume duplicate transactions are not passed by asserting after inserting each transaction to `iters_by_txid`.
- Included a Bug fix: In the current master we are underestimating the memory usage of `DisconnectedBlockTransactions`.
* When adding and subtracting `cachedInnerUsage` we call `RecursiveDynamicUsage` with `CTransaction` which invokes this [`RecursiveDynamicUsage(const CTransaction& tx)`](https://github.com/bitcoin/bitcoin/blob/6e721c923c87abdb8d99674093d08d8c17bc52c2/src/core_memusage.h#L32) version of `RecursiveDynamicUsage`, the output of that call only account for the memory usage of the inputs and outputs of the `CTransaction`, this omits the memory usage of the `CTransaction` object and the control block.
* This PR fixes this bug by calling `RecursiveDynamicUsage` with `CTransactionRef` when adding and subtracting `cachedInnerUsage` which invokes [`RecursiveDynamicUsage(const std::shared_ptr<X>& p)`](https://github.com/bitcoin/bitcoin/blob/6e721c923c87abdb8d99674093d08d8c17bc52c2/src/core_memusage.h#L67) version of `RecursiveDynamicUsage` the output of the calculation accounts for the` CTransaction` object, the control blocks, inputs and outputs memory usage.
* see [comment ](https://github.com/bitcoin/bitcoin/pull/28385#discussion_r1322948452)
- Added test for DisconnectedBlockTransactions memory limit.

The legacy serialization was vulnerable to maleation and is fixed by
adopting the same serialization procedure as was already in use for
MuHash.
This also includes necessary test fixes where the hash_serialized2 was
hardcoded as well as correction of the regtest chainparams.
