bb97b1ffa9f02bf9c05f653602cfb1cf48efb7fa test: fix intermittent timeout in p2p_seednodes.py (Martin Zumsande)
Pull request description:
Fixes#31103
On some CI runs, the seed node timer in `ThreadOpenConnection` was only started *after* the mocktime was set.
Fix this by waiting for the first connection attempt, which happens after the timer was started.
Also I noticed that the "unreachable" connections are not in fact unreachable, so that the functional test could attempt connections
to random IPs on the internet. This was already noted in https://github.com/bitcoin/bitcoin/pull/29605#discussion_r1701616675 but the suggested fix never made it in, so I added it to this PR.

The added regtest option -test=bip94 is only used in the functional
test for BIP94.
This is done because the default regtest consensus rules
should aim to follow to mainnet, not testnet.

Pull request description:
This PR removes UPnP IGD support and drops our [miniupnp](https://github.com/miniupnp/miniupnp) dependency.
Miniupnpc is a C library (somewhat) maintained by a single person which had several vulnerabilities in the past (a couple dozens are listed [here](https://cve.mitre.org/cgi-bin/cvekey.cgi?keyword=miniupnp)), some of which directly affected our software ([RCE in 2015](https://bitcoincore.org/en/2024/07/03/disclose_upnp_rce/), [OOM in 2020](https://bitcoincore.org/en/2024/07/31/disclose-upnp-oom/)).
The main purpose of this functionality is to have more (non-data-center) reachable nodes on the network. For a non-technical user running Bitcoin Core at home, the software would automatically open a port on their router to receive incoming connections. This way, users not able to manually open a port on their router would still provide the network with more resources and enhance its diversity.
However, due to past vulnerabilities (and a worry about unknown future ones) in miniupnpc this feature was disabled by default in https://github.com/bitcoin/bitcoin/pull/6795. Having it disabled by default kills (most of?) the purpose of having this functionality in the first place: someone technical enough to understand the `-upnp` startup option or the "enable UPnP" setting is most likely able to open a port on his box in the first place.
In addition, laanwj implemented PCP with a NAT-PMP fallback directly in Bitcoin Core in https://github.com/bitcoin/bitcoin/pull/30043. If we ever want to re-enable automatic NAT traversal by default in Bitcoin Core, this is the best option (and in my opinion the only sane one). The NAT-PMP fallback makes it so compatibility shouldn't be (much of) an issue.
On balance, i believe that keeping this functionality and this barely maintained C dependency has higher costs than benefits. Therefore i propose that we get rid of it.

Keep the "-upnp" option as a hidden arg for one major version in order
to show a more user friendly error to people who had this option set in
their config file.
This aims to complete our test framework BDB parser to reflect
our read-only BDB parser in the wallet codebase. This could be
useful both for making review of #26606 easier and to also possibly
improve our functional tests for the BDB parser by comparing with
an alternative implementation.

Pull request description:
This small PR adds test coverage for the `-pid` command line option, which allows to overrule the pid filename (`bitcoind.pid` by default). One can specify either a relative path (within the datadir) or an absolute one; the latter is tested using `self.options.tmpdir`. Note that the functional test file `feature_init.py` so far only contained a stress test; with this new sub-test added, both the description and the test name are adapted to be more generic.

These addrs aren't unreachable as the test claims.
Specify a (non-working) proxy to make sure the connections fails
even if the addr was reachable.
Co-authored-by: Vasil Dimov <vd@FreeBSD.org>
On some CI runs, the timer in ThreadOpenConnection was only started *after*
the mocktime was set. Fix this by waiting for the first connection attempt,
which happens after the timer was started.
Also convert some comments into log messages/add a log, so that the test
isn't completely silent.
Set `P2PConnection.p2p_connected_to_node` in
`P2PConnection.peer_connect_helper()` instead of
`TestNode.add_p2p_connection()` and
`TestNode.add_outbound_p2p_connection()`.
This way tests can create an instance of `P2PConnection` and use
`P2PConnection.peer_connect_helper()` directly.
If requested, make the SOCKS5 Python proxy redirect each connection to a
given destination. Actually act as a real proxy, connecting the
client to a destination, except that the destination is not what the
client asked for.
This would enable us to "connect" to Tor addresses from the functional
tests.

cd0edf26c07c8c615f3ae3ac040c4774dcc8e650 tracing: cast block_connected duration to nanoseconds (0xb10c)
Pull request description:
When the `validation:block_connected` tracepoint was introduced in 8f37f5c2a562c38c83fc40234ade9c301fc4e685, the connect block duration was passed in microseconds `µs`. By starting to use steady clock in fabf1cdb206e368a9433abf99a5ea2762a5ed2c0 this changed to nanoseconds `ns`. As the test only checked if the duration value is `> 0` as a plausibility check, this went unnoticed. This was detected this when setting up monitoring for block validation time as part of the Great Consensus Cleanup Revival discussion.
This change casts the duration explicitly to nanoseconds, updates the documentation, and adds a check for an upper bound to the tracepoint interface tests. The upper bound is quite lax as mining the block takes much longer than connecting the empty test block. It's however able to detect a duration passed in an incorrect unit (1000x off).
A previous version of this PR casted the duration to microseconds `µs` - however, as the last three major releases have had the duration as nanoseconds (and this went unnoticed), we assume that this is the API now and changeing it back to microseconds would break the API again.

fae44c83da982095661b034bdd01afe8ac2fb0a6 test: Remove 0.16.3 test from wallet_backwards_compatibility.py (MarcoFalke)
Pull request description:
The test checks that any wallet created with current master can not be loaded with `v0.16.3`. This is interesting documentation, however it is probably not something to keep as a test, because:
* It seems like an extremely unlikely (and unsupported) edge case that someone creates a wallet with master and then goes ahead to open it with a long EOL software version.
* A better test would be the inverse: Create a wallet with `v0.16.3` and open it with current master. This is already tested in `wallet_upgradewallet.py`, where I've added an additional balance check before upgrading the `v0.16.3` wallet.
* The test is intermittently failing when shutting down the `v0.16.3` node, for example in https://github.com/bitcoin/bitcoin/pull/30875#issuecomment-2357565564. The exact cause is unclear, but given that the test isn't worthy to keep, removing it will ensure that the error disappears.

The weight unit is merely a consensus rule detail and is largely
irrelevant for fee-rate calculations and mempool policy rules (e.g. for
package relay and TRUC limits), so there doesn't seem to be any value of
using a granularity that we can't even guarantee to reach exactly
anyway.
Switch to the more natural unit of vsize instead, which simplifies both
the padding implementation and the current tests that take use of this
padding. The rather annoying multiplications by `WITNESS_SCALE_FACTOR`
can then be removed and weird-looking magic numbers like `4004` can be
replaced by numbers that are more connected to actual policy limit
constants from the codebase, e.g. `1001` for exceeding
`TRUC_CHILD_MAX_VSIZE` by one.

Pull request description:
Re-bucket:
- `p2p_node_network_limited -v*transport`
- `feature_assume_utxo`
On CI runners these tests are taking longer than their current bucket suggests, often being among the last to finish.
Re-bucket them to improve CI efficiency.

Not doing the sync will lead to (intermittent) issues, as explained in https://github.com/bitcoin/bitcoin/issues/30922#issuecomment-2364529013.
Fix all issues by doing the sync by default and disable it in places that do not need the sync.

7e3dbe4180cbeb65e59b53d9fa98509e9189549d wallet: Write best block to disk before backup (Fabian Jahr)
Pull request description:
I discovered that we don't write the best block to disk when trying to explain the behavior described here: https://github.com/bitcoin/bitcoin/pull/30455#discussion_r1719951882
In the context of that test, the behavior is confusing and I think it also shows that one of the already existing tests in `wallet_assumeutxo.py` doesn't actually test what it says. It only fails because the best block isn't written and actually, the height of the backup that is loaded is at the snapshot height during backup. So it really shouldn't fail since it's past the background sync blocks already.
I'm not sure if this is super relevant in practice though so I am first looking for concept ACKs on the `BackupWallet` code change. Either way, I think this behavior should be documented better if it is left as is and the test should be changed.

89a8f74bbbb900abfb3d8e946eea18ad7b1513ad refactor: rename BlockKey to BlockRef (Sjors Provoost)
Pull request description:
This continues the work in #30200 so that a future Stratum v2 Template Provider (see #29432) can avoid accessing node internals. It needs to know when a new block arrives in order to push new templates to connected clients.
`waitTipChanged()` uses a new kernel notification `notifications().m_tip_block_mutex`, which this PR also introduces (a previous version used `g_best_block`).
In order to ensure the new method works as intended, the `waitfornewblock`, `waitforblock` and `waitforblockheight` RPC methods are refactored to use it. This allows removing `RPCNotifyBlockChange`.
There's a commit to add (direct) tests for the methods that are about to be refactored:
- `waitfornewblock` was already implicitly tested by `feature_shutdown.py`.
- `waitforblockheight` by `feature_coinstatsindex.py` and `example_test.py`
This PR renames `getTipHash()` to `getTip()` and returns a `BlockRef` (renamed from `BlockKey`) so that callers can use either the height or hash.
The later commits make trivial improvements to the `waitfor*` RPC calls (not needed for this PR).
The `waitTipChanged()` method could probably also be used for the longpoll functionality in `getblocktemplate`, but I'm a bit reluctant to touch that.
`RPCServer::OnStarted` no longer does anything and `RPCServer::OnStopped` merely prints a log statement. They were added in #5711 as a refactor. This PR drops them entirely.
Finally `g_best_block` is also dropped.
