fa05a726c2 tidy: modernize-use-emplace (MarcoFalke)
Pull request description:
Constructing a temporary unnamed object only to copy or move it into a container seems both verbose in code and a strict performance penalty.
Fix both issues via the `modernize-use-emplace` tidy check.

8b6470a906 gui: disable top bar menu actions during shutdown (furszy)
7066e8996d gui: provide wallet controller context to wallet actions (furszy)
Pull request description:
Small follow-up to #751.
Fixes another crash cause during shutdown. Which occurs when the user hovers over the wallets list.
Future Note:
This surely happen in other places as well, we should re-work the way we connect signals. Register
lambas without any precaution can leave dangling pointers.

All callers of `LookupSubNet()` need the result to be of CJDNS type if
`-cjdnsreachable` is set and the address begins with `fc`:
* `NetWhitelistPermissions::TryParse()`: otherwise `-whitelist=` fails
to white list CJDNS addresses: when a CJDNS peer connects to us, it
will be matched against IPv6 `fc...` subnet and the match will never
succeed.
* `BanMapFromJson()`: CJDNS bans are stored as just IPv6 addresses in
`banlist.json`. Upon reading from disk they have to be converted back
to CJDNS, otherwise, after restart, a ban entry like (`fc00::1`, IPv6)
would not match a peer (`fc00::1`, CJDNS).
* `setban()` (in `rpc/net.cpp`): otherwise `setban fc.../mask add` would
add an IPv6 entry to BanMan. Subnetting does not make sense for CJDNS
addresses, thus treat `fc.../mask` as invalid `CSubNet`. The result of
`LookupHost()` has to be converted for the case of banning a single
host.
* `InitHTTPAllowList()`: not necessary since before this change
`-rpcallowip=fc...` would match IPv6 subnets against IPv6 peers even
if they started with `fc`. But because it is necessary for the above,
`HTTPRequest::GetPeer()` also has to be adjusted to return CJDNS peer,
so that now CJDNS peers are matched against CJDNS subnets.
Opening the top bar menu when the app is being destroyed
freezes the GUI shutdown process for no reason. No menu
action can be executed.
Note:
This behavior is consistent with how the tray icon menu
is cleared too.

37b9b73477 descriptors: Move InferScript's pubkey validity checks to InferPubkey (Andrew Chow)
b7485f11ab descriptors: Check result of InferPubkey (Andrew Chow)
Pull request description:
`InferDescriptor` was not always checking that the pubkey it was placing into the descriptor was an allowed pubkey. For example, given a P2WPKH script that uses an uncompressed pubkey, it would produce a `wpkh()` with the uncompressed key. Additionally, the hybrid key check was only being done for `pk()` scripts, where it should've been done for all scripts.
This PR moves the key checking into `InferPubkey`. If the key is not valid for the context, then `nullptr` is returned and the inferring will fall through to the defaults of either `raw()` or `addr()`.
This also resolves an issue with migrating legacy wallets that contain hybrid pubkeys as such watchonly scripts will become `raw()` or `addr()` and go to the watchonly wallet. Note that a legacy wallet cannot sign for hybrid pubkeys. A test has been added for the migration case.
Also added unit tests for `InferDescriptor` itself as the edge cases with that function are not covered by the descriptor roundtrip test.

ed52e71176 Periodically check disk space to avoid corruption (Aurèle Oulès)
7fe537f7a4 Implement CCoinsViewErrorCatcher::HaveCoin (Aurèle Oulès)
Pull request description:
Attempt to fix #26112.
As suggested by sipa in https://github.com/bitcoin/bitcoin/issues/26112#issuecomment-1249683401:
> CCoinsViewErrorCatcher, the wrapper class used around CCoinsViewDB that's supposed to detect these problems and forcefully exit the application, has an override for GetCoins. But in CheckTxInputs, HaveInputs is first invoked, which on its turn calls HaveCoin. HaveCoin is implemented in CCoinsViewDB, but not in CCoinsViewErrorCatcher, and thus the disk read exception escapes.
> A solution may be to just add an override for HaveCoin in CCoinsViewErrorCatcher.
I implemented `CCoinsViewErrorCatcher::HaveCoin` and also added a periodic disk space check that shutdowns the node if there is not enough space left on disk, the minimum here is 50MB.
For reviewers, it's possible to saturate disk space to test the PR by creating large files with `fallocate -l 50G test.bin`

We make the Satisfier a base in which to store the common methods
between the Tapscript and P2WSH satisfier, and from which they both
inherit.
A field is added to SignatureData to be able to satisfy pkh() under
Tapscript context (to get the pubkey hash preimage) without wallet data.
For instance in `finalizepsbt` RPC. See also the next commits for a
functional test that exercises this.
64-hex-characters public keys are valid in Miniscript key expressions
within a Tapscript context.
Keys under a Tapscript context always serialize as 32-bytes x-only
public keys (and that's what get hashed by OP_HASH160 on the stack too).
In order to exacerbate a mistake in the stack size tracking logic,
sometimes pad the witness to make the script execute at the brink of the
stack size limit. This way if the stack size is underestimated for a
script it would immediately fail `VerifyScript`.
Under Tapscript, due to the lifting of some standardness and consensus
limits, scripts can now run into the maximum stack size during
execution. Any Miniscript that may hit the limit on any of its spending
paths must be marked as unsafe.
Co-Authored-By: Pieter Wuille <pieter@wuille.net>
We introduce another global that dictates the script context under which
to operate when running the target.
For miniscript_script, just consume another byte to set the context.
This should only affect existing seeds to the extent they contain a
CHECKMULTISIG. However it would not invalidate them entirely as they may
contain a NUMEQUAL or a CHECKSIGADD, and this still exercises a bit of
the parser.
For miniscript_string, reduce the string size by one byte and use the
last byte to determine the context. This is the change that i think
would invalidate the lowest number of existing seeds.
For miniscript_stable, we don't want to invalidate any seed. Instead of
creating a new miniscript_stable_tapscript, simply run the target once
for P2WSH and once for Tapscript (with the same seed).
For miniscript_smart, consume one byte before generating a pseudo-random
node to set the context. We have less regard for seed stability for this
target anyways.
Adapt the test data and the parsing context to support x-only keys.
Adapt the Test() helper to test existing cases under both Tapscript and
P2WSH context, asserting what needs to be valid or not in each.
Finally, add more cases that exercise the logic that was added in the
previous commits (multi_a, different resource checks and keys
serialization under Tapscript, different properties for 'd:' fragment,
..).
Under Tapscript, there is:
- No limit on the number of OPs
- No limit on the script size, it's implicitly limited by the maximum
(standard) transaction size.
- No standardness limit on the number of stack items, it's limited by
the consensus MAX_STACK_SIZE. This requires tracking the maximum stack
size at all times during script execution, which will be tackled in
its own commit.
In order to avoid any Miniscript that would not be spendable by a
standard transaction because of the size of the witness, we limit the
script size under Tapscript to the maximum standard transaction size
minus the maximum possible witness and Taproot control block sizes. Note
this is a conservative limit but it still allows for scripts more than a
hundred times larger than under P2WSH.
