576dd97cb91ecff7d95898a0dc79b9b1a8a8f4f2 test: increase timeout in p2p_leak_tx.py (Martin Zumsande)
Pull request description:
This fixes two issues with `p2p_leak_tx.py`:
1.) #33090: As far as I can see, this is just the randomness of `NextInvToInbounds`/ `rand_exp_duration`, which has a probability of `e^-(60s/5s) = 6.14×10^−6` to result in a period > 60s (our waiting time), so that the test would fail every 160k runs... Doubling the timeout should be sufficient to lower the probability drastically.
2.) The subtest `test_notfound_on_unannounced_tx` has some (w)txid confusion: we send a `MSG_TX`-type getdata with a `wtxid` in it, which necessarily always results in a NOTFOUND. Fixed this, and change the subtest to be more deterministic based on `mocktime`.

7b5261f7ef3d88361204c40eb10c0d9dc44f5ed7 contrib: fix using macdploy script without translations. (amisha)
Pull request description:
**Description**
From what I deciphered reading the line https://github.com/bitcoin/bitcoin/blob/master/contrib/macdeploy/macdeployqtplus#L390 is that qt translations are optional to have hence we should be able to build without it but the case where the flag translations_dir falls back to its default Null value it raises this error.
The config comments also mentioned that adding translation file is optional.
```
./macdeployqtplus --help
usage: macdeployqtplus [-h] [-verbose [VERBOSE]] [-no-plugins] [-no-strip] [-translations-dir path] [-zip zip] app-bundle
Improved version of macdeployqt. Outputs a ready-to-deploy app in a folder "dist" and optionally wraps it in a .zip file. Note, that the "dist" folder will be deleted before deploying on each run. Optionally, Qt translation files
(.qm) can be added to the bundle.
```
**Steps to reproduce**
So I was following the general steps to set up app on macos however I didn't download any qt translations presuming it was optional from the comment linkedin in PR, so to reproduce if you have translation directories in place ull need to delete them and then try to build the file, otherwise don't download it at all and try to build it. It should fail on that flag as translations dir was never downloaded.
**Approach taken**
I have moved the code which adds language files under the if statement that first checks if the value of the flag is not Null before referencing it.

By using the pskip pointer, which regularly allows jumping back much faster
than pprev, the forking point between two CBlockIndex entries can be found
much faster.
A simulation shows that no more than 136 steps are needed to jump anywhere
within the first 2^20 block heights, and on average 65 jumps for uniform
forking points around that height.
The other executables have manifests and these should be checked in
addition to bitcoind. Skipping fuzz.exe, bench_bitcoin.exe and
test_bitcoin-qt.exe as they do not have manifests.
This sets up a vs developer command prompt and should hopefully should
be more resilient to upstream changes

Pull request description:
This was the intended behavior but our tests didn't cover the scenario where in-block transactions themselves violate TRUC topological constraints.
The behavior in master will potentially lead to many erroneous evictions during a reorg, where evicted TRUC packages may be very high feerate and make sense to mine all together in the next block and are well within the normal anti-DoS chain limits.
This issue exists since the merge of https://github.com/bitcoin/bitcoin/pull/28948/files#diff-97c3a52bc5fad452d82670a7fd291800bae20c7bc35bb82686c2c0a4ea7b5b98R956

Use the {Arg,MaybeArg}<std::string_view> helper in all places where
it is a trivial change. In many places, this simplifies the logic
and reduces duplication of default values.
Update select functions that take a const std::string& to take a
std::string_view instead. In a next commit, this allows us to use
the {Arg,MaybeArg}<std::string_view> helper.
Modernizes interface by not forcing users to deal with raw pointers,
without adding copying overhead. Generalizes the logic of whether
we return by value or by optional/pointer.
In cases where functions take a `const std::string&` and it would
be too much work to update them, a string copy is made (which was
already happening anyway).
Normally `ConnectNode()` would choose whether to use a proxy and which
one. Make it possible to override this from the callers and same for
`OpenNetworkConnection()` - pass down the proxy to `ConnectNode()`.
Document both functions.
This is useful if we want to open connections to IPv4 or IPv6 peers
through the Tor SOCKS5 proxy.
Also have `OpenNetworkConnection()` return whether the connection
succeeded or not. This can be used when the caller needs to keep track
of how many (successful) connections were opened.
When the assumevalid ancestry check fails, log a precise reason:
- "block height above assumevalid height" if the block is above the assumevalid block (the default reason)
- "block not in of assumevalid chain" otherwise
The new split was added under the existing condition to simplify conceptually that the two cases are related.
It could still be useful to know when the block is just above the assumevalid block or when it's not even on the same chain.
Update the functional test to assert the new reason strings. No behavior change.

Pull request description:
`CConnman::FindNode()` would lock `m_nodes_mutex`, find the node in `m_nodes`, release the mutex and return the node. The current code is safe but it is a dangerous interface where a caller may end up using the node returned from `FindNode()` without owning `m_nodes_mutex` and without having that node's reference count incremented.
Change `FindNode()` to return a boolean since all but one of its callers used its return value to check whether a node exists and did not do anything else with the return value.
Remove a recursive lock on `m_nodes_mutex`.
Rename `FindNode()` to better describe what it does.

Signal m_tip_block_cv when Ctrl-C is pressed or SIGTERM is received, the same
way it is currently signalled when the `stop` RPC is called. This lets RPC
calls like `waitforblockheight` and IPC calls like `waitTipChanged` be
interrupted, instead of waiting for their original timeouts and delaying
shutdown.
Historical notes:
- The behavior where `stop` RPC signals `m_tip_block_cv`, but CTRL-C does not,
has been around since the condition variable was introduced in #30409
(7eccdaf16081d6f624c4dc21df75b0474e049d2b).
- The signaling was later moved without changing behavior in #30967
(5ca28ef28bcca1775ff49921fc2528d9439b71ab). This commit moves it again to
the Interrupt() function, which is probably the place it should have been
added initially, so it works for Ctrl-C shutdowns as well as `stop`
shutdowns.
- A Qt shutdown bug calling wait methods was fixed previously in #18452
(da73f1513a637a9f347b64de66564d6cdb2541f8), and this change updates that
fix to avoid the hang happening again in Qt.
The returned value in `getpeerinfo/addr` could be a hostname as well as
an IP address and the `:port` part could be missing. It is displayed
from `CNode::m_addr_name` which could have been set from RPC `addnode`
where the argument is allowed to be a hostname and an optional port.
All callers of `CConnman::FindNode()` use its return value `CNode*` only
as a boolean null/notnull. So change that method to return `bool`.
This removes the dangerous pattern of handling a `CNode` object (the
return value of `FindNode()`) without holding `CConnman::m_nodes_mutex`
and without having that object's reference count incremented for the
duration of the usage.
Also rename the method to better describe what it does.
Have `CConnman::DisconnectNode()` iterate `m_nodes` itself instead of
using `FindNode()`. This avoids recursive mutex lock and drops the only
caller of `FindNode()` which used the return value for something else
than a boolean found/notfound.

Extend `CConnman` fuzz tests to also exercise the methods `OpenNetworkConnection()`, `CreateNodeFromAcceptedSocket()`, `InitBinds()` and `SocketHandler()`.
Previously fuzzing those methods would have resulted in real socket functions being called in the operating system which is undesirable during fuzzing. Now that https://github.com/bitcoin/bitcoin/pull/21878 is complete all those are mocked to a fuzzed socket and a fuzzed DNS resolver (see how `CreateSock` and `g_dns_lookup` are replaced in the first commit).

451ba9ada41f687c0e4bb34d5925374a68a8f8a3 datacarrier: Undeprecate configuration option (Anthony Towns)
Pull request description:
Removes the deprecation for the `datacarrier` and `datacarriersize` options by reverting commit 0b4048c73385166144d0b3e76beb9a2ac4cc1eca from https://github.com/bitcoin/bitcoin/pull/32406
**Many current Bitcoin Core users want to continue using this option**
This statement is based on public postings from many Bitcoin Core users and not a formal survey. AJ Towns’ observation from [#32406](0b4048c733 (r2084024874)) that “_for now there seem to be a bunch of users who like the option_” has only become more apparent in the months since.
**The deprecation intent is unclear to users**
This echo’s Ava Chow’s comment from #32714 that “_IMO we should not have removal warnings if there is no current plan to actually remove them._” In months since that comment, partially due to increased feedback from Bitcoin Core users wanting to keep this option, there is even less likelihood of a near term plan to remove these options. That leaves Bitcoin Core users in an unclear situation: the option could be removed in the next version or perhaps never. Removing the deprecation gives clarity for their planning purposes. Deprecating the option in the future, preferably with a removal schedule to better inform users, would still be possible.
**Minimal downsides to removing deprecation**
As a best practice, Bitcoin Core has avoided an option when the developers cannot articulate when they should be used. There is non-zero maintenance cost to keeping this code around (although leaving the options deprecated for a long time has the same effect). “Don’t offer users footguns” is also a good principle, but with this option, there seems to be only small impacts that can quickly be remedied by changing the option value by Bitcoin Core users. There already exist in Bitcoin Core more potentially-user-harmful options/values than what datacarrier might cause.

fabc2615af26c61a503f23ae4fd0353f90602bbe test: Use extra_port() helper in feature_bind_extra.py (MarcoFalke)
Pull request description:
This is a refactor for self-validating and self-documenting code.
Currently, the test assumes that extra ports are available and just increments them without checking. However, this may not be the case when the test is modified to use more ports. In this case, the tests may fail intermittently and the failure is hard to debug.
Fix this confusion, by calling `p2p_port` each time. This ensures the required `assert n <= MAX_NODES` is checked each time.

Currently when CTRL-C is pressed and there is an active `waitforblockheight`,
or `waitforblock`, or `waitfornewblock` RPC call, or a mining interface
`waitTipChanged` IPC call with a long timeout, the node will not shut down
right away, and will wait for the timeout to be reached before exiting.
This behavior is not ideal and only happens when the node is stopped with
CTRL-C or SIGTERM. When the node is stopped with `bitcoin-cli stop`, the wait
calls are interrupted and the node does shut down right away.
The next commit improves node behavior. This commit just adds test coverage to
simplify the next commit and clarify the change in behavior there.
When creating Taproot signatures, if the key being signed for is known
to be a MuSig2 aggregate key, do the MuSig2 signing algorithms.
First try to create the aggregate signature. This will fail if there are
not enough partial signatures or public nonces. If it does fail, try to
create a partial signature with all participant keys. This will fail for
those keys that we do not have the private keys for, and if there are
not enough public nonces. Lastly, if the partial signatures could not be
created, add our own public nonces for the private keys that we know, if
they do not yet exist.
A common pattern that MuSig2 functions will use is to aggregate the
pubkeys to get the keyagg_cache and then validate the aggregated pubkey
against a provided aggregate pubkey. A variant of MuSig2AggregatePubkeys
is added which does that.
The functionality of GetMuSig2KeyAggCache and GetCPubKeyFromMuSig2KeyAggCache
are included in MuSig2AggregatePubkeys (and used internally) so there is
no expectation that callers will need these so they are made static.
Adds GetMuSig2SecNonces which returns secp256k1_musig_secnonce*, and
DeleteMuSig2Session which removes the MuSig2 secnonce from wherever it
was retrieved. FlatSigningProvider stores it as a pointer to a map of
session id to secnonce so that deletion will actually delete from the
object that actually owns the secnonces.
The session id is just a unique identifier for the caller to determine
what secnonces have been created.
