e667bd68a10512ddc784df44bdcb63ee441e5551 test: fix intermittent failure in wallet_resendwallettransactions.py (Martin Zumsande)
Pull request description:
Fixes#28094
The test bumps the mocktime for ~2 weeks and then triggers eviction from the mempool. But this bump will also cause a new resubmit, and if the timing is such that this resubmit happens right after the eviction and before the check that the tx was evicted, the test can fail as in #28094:
```

```
Fix this by flushing out the current resubmit call before triggering mempool eviction.

286e0c7d5e9538198b28b792c5168b8fafa1534f wallet: loading, log descriptor parsing error details (furszy)
Pull request description:
Linked to #28057.
Currently, the `InferScript` function returns an invalid descriptor when it tries to infer a p2sh-p2pkh script whose pubkey is not known by the wallet.
This behavior occurs because the inference process bypasses the `pkh` subscript when the pubkey is not contained by the wallet (no pubkey provider), interpreting it as a `sh(addr(ADDR))` descriptor. Then, the failure arises because the `addr()` function is restricted to being used only at the top level.
For reviewers, would recommend to start by examining the functional test to understand the context and the circumstances on which this can result in a fatal error (e.g. during the migration process).

bbbb89d238e9bdaa9f426d55b0a3b714dac1d39b test: miner: add coverage for `-blockmintxfee` setting (Sebastian Falbesoner)
Pull request description:
This PR adds missing test coverage for the `-blockmintxfee` option, which can be used by miners to specify the lowest fee-rate for transactions to be included in blocks. The setting was introduced in PR #9380 (commit daec955fd68bd0da036a5b446b54ffb01108adcd), with the rationale to decouple different minimum fees from `-minrelaytxfee`. According to the PR description it _"should be set by miners to reflect their marginal cost of transmitting extra bytes."_.
On each iteration, the test creates and submits two txs using MiniWallet: one with the the minimum fee-rate as specified for `-blockmintxfee` and a second one with a fee-rate a little below that (-0.01 sats/vbyte). Then it checks that only the first one is picked for the block template and accordingly also only exists in the block that is mined after. This is repeatedly done for a fixed (but obviously somewhat arbitrary) list of different `-blockmintxfee` settings on a single node, including the default and zero (i.e. no minimum fee a.k.a. "include even zero-fee txs") settings.

Pull request description:
When bumping the transaction fee, we will try to find the change output of the transaction in order to have an output whose value we can modify so that we can meet the target feerate. However we do not always find the change output which can cause us to unnecessarily add an additional output to the transaction. We can avoid this issue by outsourcing the determination of change to the user if they so desire.
This PR adds a `orig_change_pos` option to bumpfee which the user can use to specify the index of the change output.

5cf44275c8ca8c32d238f37f717d78e9823f44c2 test: refactor: deduplicate legacy ECDSA signing for tx inputs (Sebastian Falbesoner)
Pull request description:
There are several instances in functional tests and the framework (MiniWallet, feature_block.py, p2p_segwit.py) where we create a legacy ECDSA signature for a certain transaction's input by doing the following steps:
1. calculate the `LegacySignatureHash` with the desired sighash type
2. create the actual digital signature by calling `ECKey.sign_ecdsa` on the signature message hash calculated above
3. put the DER-encoded result as CScript data push into tx input's scriptSig
Create a new helper `sign_input_legacy` which hides those details and takes only the necessary parameters (tx, input index, relevant scriptPubKey, private key, sighash type [SIGHASH_ALL by default]). For further convenience, the signature is prepended to already existing data-pushes in scriptSig, in order to avoid rehashing the transaction after calling the new signing function.

By moving the 'StartIndexes()' call into the 'initload'
thread, we can remove the threads active wait. Optimizing
the available resources.
The only difference with the current state is that now the
indexes threads will only be started when they can process
work and not before it.
The thread does not only load blocks, it loads the mempool and,
in a future commit, will start the indexes as well.
Also, renamed the 'ThreadImport' function to 'ImportBlocks'
And the 'm_load_block' class member to 'm_thread_load'.

Pull request description:
This PR rewrites a portion of `test_framework/key.py`, in a compatible way, by introducing classes that encapsulate field element and group element logic, in an attempt to be more readable and reusable.
To maximize readability, the group element logic does not use Jacobian coordinates. Instead, group elements just store (affine) X and Y coordinates directly. To compensate for the performance loss this causes, field elements are represented as fractions. This undoes most, but not all, of the performance loss, and there is a few % slowdown (as measured in `feature_taproot.py`, which heavily uses this).
The upside is that the implementation for group laws (point doubling, addition, subtraction, ...) is very close to the mathematical description of elliptic curves, and this extends to potential future extensions (e.g. ElligatorSwift as needed by #27479).

Pull request description:
After initially being merged in #20487, it's no-longer clear that an internal syscall sandboxing mechanism is something that Bitcoin Core should have/maintain, especially when compared to better maintained/supported alterantives, i.e [firejail](https://github.com/netblue30/firejail).
There is more related discussion in #24771.
Note that given where it's used, the sandbox also gets dragged into the kernel.
If it's removed, this should not require any sort of deprecation, as this was only ever an opt-in, experimental feature.
Closes#24771.

Pull request description:
The functional test feature_taproot.py fails in some rare cases on the execution of the following `"branched_codesep"` spending script (can be reproduced via `$ ./test/functional/feature_taproot.py --randomseed 9048710178866422833` on master / 137a98c5a22e058ed7a7997a0a4dbd75301de51e):
9d85c03620/test/functional/feature_taproot.py (L741)
The problem occurs if the first data-push (having random content with a random length in the range [0, 510]) has a length of 1 and the single byte has value of [1...16] or [-1]; in this case, the data-push is not minimally encoded by test framework's CScript class (i.e. doesn't use the special op-codes OP_1...OP_16 or OP_1NEGATE) and the script interpreter throws an SCRIPT_ERR_MINIMALDATA error:
```
test_framework.authproxy.JSONRPCException: non-mandatory-script-verify-flag (Data push larger than necessary) (-26)
```
Background: the functional test framework's CScript class translates passed bytes/bytearrays always to data pushes using OP_PUSHx/OP_PUSHDATA{1,2,4} op-codes (see `CScript.__coerce_instance(...)`). E.g. the expression `CScript(bytes([1]))` yields `bytes([OP_PUSH1, 1])` instead of the minimal-encoded `bytes([OP_1])`.
Fix this by adapting the random-size range to [2,...], i.e. never pass byte-arrays below length two to be pushed.
Closes#27595.

30778124b82791abdc6e930373460ef1dd587cb2 net: Give seednodes time before falling back to fixed seeds (Martin Zumsande)
Pull request description:
`-seednode` is an alternative bootstrap mechanism - when choosing it, we make a `AddrFetch` connection to the specified peer, gather addresses from them, and then disconnect. Presumably, if users specify a seednode they prefer addresses from that node over fixed seeds.
However, when disabling dns seeds and specifiying `-seednode`, `CConnman::ProcessAddrFetch()` immediately removes the entry from `m_addr_fetches` (before the seednode could give us addresses) - and once `m_addr_fetches` is empty, `ThreadOpenConnections` will add fixed seeds, resulting in a "race" between the fixed seeds and seednodes filling up AddrMan.
This PR suggests to check for any provided `-seednode` arg instead of using the size of `m_addr_fetches`, thus delaying the querying of fixed seeds for 1 minute when specifying any seednode (as we already do for `addnode` peers).
That way, we actually give the seednodes a chance for to provide us with addresses before falling back to fixed seeds.
This can be tested with `bitcoind -debug=net -dnsseed=0 -seednode=(...)` on a node without `peers.dat` and observing the debug log.

61f4b9b7ad6e992a9dbbbb091e9b7ba9abe529ac Manage exceptions in bcc callback functions (virtu)
Pull request description:
Address #27380 (and similar future issues) by handling failed `assert_equal()` assertions in bcc callback functions
### Problem
Exceptions are not propagated in ctype callback functions used by bcc. This means an AssertionError exception raised by `assert_equal()` to signal a failed assertion is not getting caught and properly logged. Instead, the error is logged to stdout and execution of the callback stops.
The current workaround to check whether all `assert_equal()` assertions in a callback succeeded is to increment a success counter after the assertions (which only gets incremented if none exception is raised and stops execution). Then, outside the callback, the success counter can be used to check whether a callback executed successfully.
One issue with the described workaround is that when an exception occurs, there is no way of telling which of the `assert_equal()` statements caused the exception; moreover, there is no way of inspecting how the pieces of data that got compared in `assert_equal()` differed (often a crucial clue when debugging what went wrong).
This problem is happening in #27380: Sporadically, in the `mempool:rejected` test, execution does not reach the end of the callback function and the success counter is not incremented. Thus, the test fails when comparing the counter to its expected value of one. Without knowing which of the asserts failed any why it failed, this issue is hard to debug.
### Solution
Two fixes come to mind. The first involves having the callback function make event data accessible outside the callback and inspecting the event using `assert_equal()` outside the callback. This solution still requires a counter in the callback in order to tell whether a callback was actually executed or if instead the call to perf_buffer_poll() timed out.
The second fix entails wrapping all relevant `assert_equal()` statements inside callback functions into try-catch blocks and manually logging AssertionErrors. While not as elegant in terms of design, this approach can be more pragmatic for more complex tests (e.g., ones involving multiple events, events of different types, or the order of events).
The solution proposed here is to select the most pragmatic fix on a case-by-case basis: Tests in `interface_usdt_net.py`, `interface_usdt_mempool.py` and `interface_usdt_validation.py` have been refactored to use the first approach, while the second approach was chosen for `interface_usdt_utxocache.py` (partly to provide a reference for the second approach, but mainly because the utxocache tests are the most intricate tests, and refactoring them to use the first approach would negatively impact their readability). Lastly, `interface_usdt_coinselection.py` was kept unchanged because it does not use `assert_equal()` statements inside callback functions.

1a572ce7d6e2b8282c6ad457cf8ecd2cf5ab7fd6 test: refactor: introduce `generate_keypair` helper with WIF support (Sebastian Falbesoner)
Pull request description:
In functional tests it is a quite common scenario to generate fresh elliptic curve keypairs, which is currently a bit cumbersome as it involves multiple steps, e.g.:
privkey = ECKey()
privkey.generate()
privkey_wif = bytes_to_wif(privkey.get_bytes())
pubkey = privkey.get_pubkey().get_bytes()
Simplify this by providing a new `generate_keypair` helper function that returns the private key either as `ECKey` object or as WIF-string (depending on the boolean `wif` parameter) and the public key as byte-string; these formats are what we mostly need (currently we don't use `ECPubKey` objects from generated keypairs anywhere).
With this, most of the affected code blocks following the pattern above can be replaced by one-liners, e.g.:
privkey, pubkey = generate_keypair(wif=True)
Note that after this commit, the only direct uses of `ECKey` remain in situations where we want to set the private key explicitly, e.g. in MiniWallet (test/functional/test_framework/wallet.py) or the test for the signet miner script (test/functional/tool_signet_miner.py).

Instead of passing the datadir and chain name to os.path.join, just use
the existing properties, which are the same.

Seems odd to hardcode all parent directory names in the path for no good
reason.
Also, add wallet_path property to TestNode.
Also, rework wallet_backup.py test for scripted-diff in the next commit.

Pull request description:
Fixes#27555
The issue arises when an old `fee_estimates.dat` file is sometimes read during initialization.
Or after an unclean shutdown, the latest fee estimates are not flushed to `fee_estimates.dat`.
If the fee estimates in the old file are old, they can cause transactions to become stuck in the mempool.
This PR ensures that nodes do not use stale estimates from the old file during initialization. If `fee_estimates.dat`
has not been updated for 60 hours or more, it is considered stale and will not be read during initialization. To avoid
having old estimates, the `fee_estimates.dat` file will be flushed periodically every hour. As mentioned #27555
> "The immediate improvement would be to store fee estimates to disk once an hour or so to reduce the chance of having an old file. From there, this case could probably be detected, and refuse to serve estimates until we sync."
In addition, I will follow-up PR to persist the `mempoolminfee` across restarts.
