Pull request description:
Only one small part of the pruning test (sub-test `wallet_test`) is wallet-related, hence we can run all other parts without wallet compiled.

fa37e798b2660d8e44e31c944a257b55aeef5de2 wallet: Replace confusing getAdjustedTime() with GetTime() (MarcoFalke)
Pull request description:
Setting `nTimeReceived` to the adjusted time has several issues:
* `m_best_block_time` is set to the "unadjusted" time, thus a comparison of the two times is like comparing apples to oranges. In the worst case this opens up an attack vector where remote peers can force a premature re-broadcast of wallet txs.
* The RPC documentation for `"timereceived"` doesn't mention that the network adjusted time is used, possibly confusing users when the time reported by RPC is off by a few seconds compared to their local timestamp.
Fix all issues by replacing the call with `GetTime()`. Also a style fix: Use non-narrowing integer conversion in the RPC method.

747cd17404832604c50d03d58e11ba816bb229f7 build: no-longer fail default configure if BDB isn't available (fanquake)
Pull request description:
Inline with moving to descriptor (sqlite) wallets by default for 0.23,
this adapts the build system so that a default `./configure` invocation
no-longer fails if BDB isn't present. Currently, if configure is run
with no options, and no BDB is present, we'll fail with:
```bash
checking for Berkeley DB C++ headers... no
configure: error: libdb_cxx headers missing, Bitcoin Core requires this library for BDB wallet support (--without-bdb to disable BDB wallet support)
```
If descriptor wallets are to be the default, this behaviour no longer
makes sense, as a builder should be able to configure and build, to use
a wallet, without BDB installed, and without passing additional
arguments, i.e `--without-bdb` or `--with-incompatible-bdb`, to
configure.
With this change, running configure will no-longer fail, but will
instead print:
```bash
checking for Berkeley DB C++ headers... no
configure: WARNING: libdb_cxx headers missing
configure: WARNING: Bitcoin Core requires this library for BDB (legacy) wallet support
configure: WARNING: Passing --without-bdb will suppress this warning
checking for sqlite3 >= 3.7.17... yes

## Issue being fixed or feature implemented
Slightly changes the detached signature creation code
## What was done?
Investigated what exactly needed to be done for notarization (docs to
come), tried it again, then when it failed as expected trying to figure
it out, then figuring it out :) simple change in the end.
## How Has This Been Tested?
created macOS detached sigs and notarized 19.0.0-rc.10 binaries and
ensured that all worked as expected. See binary attached here (sha256

You can also do a signed gitian-build for rc.10 and should replicate
these hashes.
## Breaking Changes
Should be none; I would like to backport this to 19 as a 19.0.1

73b96c94cb6c2afdee7f151768a96944ecaf9d9b net: Fix uninitialized read in ProcessMessage(...) (practicalswift)
Pull request description:
Fix an uninitialized read in `ProcessMessage(…, "tx", …)` when receiving a transaction we already have.
The uninitialized value is read and used on [L2526 in the case of `AlreadyHave(inv) == true`](d8a66626d6/src/net_processing.cpp (L2494-L2526)).
Proof of concept being run against a `bitcoind` built with MemorySanitizer (`-fsanitize=memory`):

Usage: ./p2p-uninit-read-in-conditional-poc.py <dstaddr> <dstport> <net>
$ bitcoind -regtest &
$ ./p2p-uninit-read-in-conditional-poc.py 127.0.0.1 18444 regtest
SUMMARY: MemorySanitizer: use-of-uninitialized-value
[1]+ Exit 77 bitcoind -regtest
$
```
Proof of concept being run against a `bitcoind` running under Valgrind (`valgrind --exit-on-first-error`):
```
$ valgrind -q --exit-on-first-error=yes --error-exitcode=1 bitcoind -regtest &
$ ./p2p-uninit-read-in-conditional-poc.py 127.0.0.1 18444 regtest
==27351== Conditional jump or move depends on uninitialised value(s)
[1]+ Exit 1 valgrind -q --exit-on-first-error=yes --error-exitcode=1 bitcoind -regtest
$
```
Proof of concept script:
```
#!/usr/bin/env python3
import sys
from test_framework.mininode import NetworkThread
from test_framework.mininode import P2PDataStore
from test_framework.messages import CTransaction, CTxIn, CTxOut, msg_tx
def send_duplicate_tx(dstaddr="127.0.0.1", dstport=18444, net="regtest"):

network_thread.start()
node = P2PDataStore()
node.peer_connect(dstaddr=dstaddr, dstport=dstport, net=net)()
node.wait_for_verack()
tx = CTransaction()
tx.vin.append(CTxIn())
tx.vout.append(CTxOut())
node.send_message(msg_tx(tx))
node.send_message(msg_tx(tx))
node.peer_disconnect()
network_thread.close()
if __name__ == "__main__":
if len(sys.argv) != 4:
print("Usage: {} <dstaddr> <dstport> <net>".format(sys.argv[0]))
sys.exit(0)
send_duplicate_tx(sys.argv[1], int(sys.argv[2]), sys.argv[3])
```
Note that the transaction in the proof of concept is the simplest possible, but really any transaction can be used. It does not have to be a valid transaction.
This bug was introduced in #15921 ("validation: Tidy up ValidationState interface") which was merged in to `master` 28 days ago.
Luckily this bug was caught before being part of any Bitcoin Core release :)

Pull request description:
Carries out some remaining tidy-ups remaining after PR 15141:
- split ValidationState into TxValidationState and BlockValidationState (commit from ajtowns)
- various minor code style tidy-ups to the ValidationState class
- remove the useless `ret` parameter from `ValidationState::Invalid()`
- remove the now unused `first_invalid` parameter from `ProcessNewBlockHeaders()`
- remove the `fMissingInputs` parameter from `AcceptToMemoryPool()`, and deal with missing inputs the same way as other errors by using the `TxValidationState` object.
Tip for reviewers (thanks ryanofsky!): The first commit ("[validation] Add CValidationState subclasses" ) is huge and can be easier to start reviewing if you revert the rote, mechanical changes:
Substitute the commit hash of commit "[validation] Add CValidationState subclasses" for <CommitHash> in the commands below.
```sh
git checkout <CommitHash>
git grep -l ValidationState | xargs sed -i 's/BlockValidationState\|TxValidationState/CValidationState/g'
git grep -l ValidationResult | xargs sed -i 's/BlockValidationResult\|TxValidationResult/ValidationInvalidReason/g'
git grep -l MaybePunish | xargs sed -i 's/MaybePunishNode\(ForBlock\|ForTx\)/MaybePunishNode/g'
git diff HEAD^
```
After that it's possible to easily see the mechanical changes with:
```sh
git log -p -n1 -U0 --word-diff-regex=. <CommitHash>
```

Pull request description:
We no longer send BIP 61 REJECT messages, so there's no need to set
a REJECT code in the CValidationState object.
Note that there is a minor bug fix in p2p behaviour here. Because the
call to `MaybePunishNode()` in `PeerLogicValidation::BlockChecked()` only
previously happened if the REJECT code was > 0 and < `REJECT_INTERNAL`,
then there are cases were `MaybePunishNode()` can get called where it
wasn't previously:
- when `AcceptBlockHeader()` fails with `CACHED_INVALID`.
- when `AcceptBlockHeader()` fails with `BLOCK_MISSING_PREV`.
Note that `BlockChecked()` cannot fail with an 'internal' reject code. The
only internal reject code was `REJECT_HIGHFEE`, which was only set in
ATMP.
This reverts a minor bug introduced in 5d08c9c579.

Pull request description:
This is another general improvement extracted from #16800 .
Two functions are added are:
* Vector(arg1,arg2,arg3,...) constructs a vector with the specified arguments as elements. The vector's type is derived from the arguments. If some of the arguments are rvalue references, they will be moved into place rather than copied (which can't be achieved using list initialization).
* Cat(vector1,vector2) returns a concatenation of the two vectors, efficiently moving elements when relevant.
Vector generalizes (and replaces) the `Singleton` function in src/descriptor.cpp, and `Cat` replaces the function in bech32.cpp

Pull request description:
Before it was 0 by default for main and 20000 for test and regtest.
Now it is 0 by default for all chains, thus there's no need to call Params().
Also now the default for main is properly documented.
Suggestion for release notes:
-fallbackfee was 0 (disabled) by default for the main chain, but 20000 by default for the test chains. Now it is 0 by default for all chains. Testnet and regtest users will have to add fallbackfee=20000 to their configuration if they weren't setting it and they want it to keep working like before.
Should I propose them to the wiki for the release notes or only after merge?

5449d44e37982fcd5251fd47873c5f7d34c39fc9 scripts: prevent GCC optimising test symbols in test-symbol-check (fanquake)
Pull request description:
I noticed in #22381 that when the test-symbol-check target was being built with Clang and run in the CI it would fail due to using a too-new version of `pow` (used [here](d67330d112/contrib/devtools/test-symbol-check.py (L85))). Our CIs use Focal (glibc 2.31) and the version of `pow` was the optimized version introduced in [glibc 2.29](https://lwn.net/Articles/778286/):
```bash
* Optimized generic exp, exp2, log, log2, pow, sinf, cosf, sincosf and tanf.
```
This made sense, except for that if it was failing when built using Clang, why hadn't it also been failing when being built with GCC?
Turns out GCC is optimizing away that call to `pow` at all optimization levels, including `-O0`, see: https://godbolt.org/z/53MhzMxT7, and this has been the case forever, or at least since GCC 5.x. Clang on the other hand, will only optimize away the `pow` call at `-O1` and `-O2`, not `-O0`: https://godbolt.org/z/Wbnqj3q6c. Thus when this test was built with Clang (we don't pass `-O` so we default to `-O0`) it was failing in the CI environment, because it would actually have a call to the "new" `pow`.
Avoid this issue by using a symbol that won't be optimized away, or that we are unlikely to ever have versioning issues with.

5c5d0b62648e1b144b7b93c199f45265dac100e5 Add FoundBlock.found member (Russell Yanofsky)
Pull request description:
This change lets IPC serialization code handle FoundBlock arguments more simply and efficiently. Without this change there was no way to determine from a FoundBlock object whether a block was found or not. So in order to correctly implement behavior of leaving FoundBlock output variables unmodified when a block was not found, IPC code would have to read preexisting output variable values from the local process, send them to the remote process, receive output values back from the remote process, and save them to output variables unconditionally. With FoundBlock.found method, the process is simpler. There's no need to read or send preexisting local output variable values, just to read final output values from the remote process and set them conditionally if the block was found.

which I took straight from the PSBT test vectors. The reason is that in src/psbt.h we call `DeserializeHDKeypaths`, which in turn calls `CPubKey::IsFullyValid`, which in turn asserts that a secp context has been created.
The error appears to be masked on many systems by the definition of `instance_of_eccryptoclosure` in src/script/bitcoinconsensus.cpp, which defines a static object which contains an `ECCVerifyHandle`. If you just comment out that line you can reliably trigger the fuzz test failure, e.g. by creating a file `crash` with the above PSBT, and runnnig

d44a261acff40c1c8727d3cc0106bde65a6416d0 Fix issues when `walletdir` is root directory (unknown)
Pull request description:
+ Remove one character less from wallet path
+ After testing lot of random strings with special chars in `wallet_name`, I found that the issue was not related to special characters in the name. Reviewing PR https://github.com/bitcoin/bitcoin/pull/21907 helped me resolve the issue.
**Real issue**: If the path mentioned in `walletdir` is a root directory, first character of the wallet name or path is removed
**Solution**: `if` statement to check `walletdir` is a root directory

but it doesn't have the [`fopencookie()` function](https://www.gnu.org/software/libc/manual/html_node/Streams-and-Cookies.html), or define the `cookie_io_functions_t` type, which results in compile failures:

Just skip trying to use it if we are building for Android. Should fix#22062.

5e146022daa4336de94447e5b8e5418296286927 wallet: fix scanning progress calculation for single block range (Sebastian Falbesoner)
Pull request description:
If the blockchain is rescanned for a single block (i.e. start and stop hashes are equal, and with that also the estimated start/stop verification progress values) the progress calculation could lead to a NaN value caused by a division by zero (0.0/0.0), resulting in an invalid JSON result for the `getwalletinfo` RPC. This PR fixes this behaviour by setting the progress to zero in that special case. Fixes#20297.
The behaviour can easily be reproduced by continuously running single block rescans in an endless loop, e.g. via
```bash
#!/bin/bash
while true
do
bitcoin-cli rescanblockchain $(bitcoin-cli getblockcount)
done
```
and at the same time perform some `getwalletinfo` RPCs.
On the master branch, this leads to frequent invalid responses (tested on mainchain):
```
$ bitcoin-cli getwalletinfo
error: couldn't parse reply from server
$ curl --user `cat ~/.bitcoin/.cookie` --data-binary '{"jsonrpc": "1.0", "id": "curltest", "method": "getwalletinfo", "params": []}' -H 'content-type: text/plain;' http://127.0.0.1:8332/
{"result":{"walletname":"","walletversion":169900,"format":"bdb","balance":0.00000000,"unconfirmed_balance":0.00000000,"immature_balance":0.00000000,"txcount":0,"keypoololdest":1603677276,"keypoolsize":1000,"hdseedid":"3196e33ecb47c7130e6ca60f2f895f9259860dca","keypoolsize_hd_internal":1000,"paytxfee":0.00000000,"private_keys_enabled":true,"avoid_reuse":false,"scanning":{"duration":0,"progress":},"descriptors":false},"error":null,"id":"curltest"}
```
(note that missing value for "progress" in the JSON result).
On the PR branch, the behaviour doesn't occur anymore.
