In both RPC commands `send()` and `walletcreatefundedpsbt` the RPC help was saying
that `add_inputs` default value was false when it's actually dynamically set
by the following statement:
`coin_control.m_allow_other_inputs = rawTx.vin.size() == 0;`
Which means that, by default, `add_inputs` is true unless there
was any pre-set input, in which case, the default is false.
in TestingSetup(). This is used in the following commit to test
reinitializing chainstates after snapshot validation and cleanup.
Best reviewed with `git diff --color-moved=dimmed-zebra`.
This CreateAndActivateUTXOSnapshot parameter is necessary once we
perform snapshot completion within ABC, since the existing UpdateTip
test will fail because the IBD chain that has generated the snapshot
will exceed the base of the snapshot.
Being able to test snapshots being loaded into a mostly-uninitialized
datadir allows for more realistic unittest scenarios.
If we call FlushBlockFile() without having intitialized the block index
with LoadBlockIndexDB(), we may be indexing into an empty vector.
Specifically this is an issue when we call MaybeRebalanceCaches() during
chainstate init before the block index has been loaded, which calls
FlushBlockFile().
Also add an assert to avoid undefined behavior.

If a UTXO snapshot fails to validate, don't leave the resulting datadir
on disk as this will confuse initialization on next startup and we'll
get an assertion error.
Used in later commits to remove leveldb directories for
- invalid snapshot chainstates, and
- background-vaildation chainstates that have finished serving their
purpose.
Add functionality for activating a snapshot-based chainstate if one is
detected on-disk.
Also cautiously initialize chainstate cache usages so that we don't
somehow blow past our cache allowances during initialization, then
rebalance at the end of init.
Co-authored-by: Russell Yanofsky <russ@yanofsky.org>
This changes the snapshot's leveldb chainstate dir name from
`chainstate_[blockhash]` to `chainstate_snapshot`. This simplifies
later logic that loads snapshot data, and enforces the limitation
of a single snapshot at any given time.
Since we still need to persis the blockhash of the base block, we
write that out to a file (`chainstate_snapshot/base_blockhash`) for
later use during initialization, so that we can reinitialize the
snapshot chainstate.

e06676377d wallet: coverage for loading an unknown descriptor (furszy)
d26c3cc444 wallet: bugfix, load wallet with an unknown descriptor cause fatal error (furszy)
Pull request description:
Fixes #26015
If the descriptor entry is unrecognized (due a soft downgrade) or corrupt, the
unserialization fails and `LoadWallet`, instead of stop there and return the error,
continues reading all the db records. As other records tied to the unrecognized
or corrupt descriptor are scanned, a fatal error is being thrown.
This fixes it by catching the descriptor parse failure and return which wallet failed.
Logging its name/path, so the user can remove it from the settings file, to prevent
its load at startup.
Note: added the test in a separate file intentionally.
Will continue adding coverage for the wallet load process in follow-up PRs.

00eeb31c76 scripted-diff: rename CChainState -> Chainstate (James O'Beirne)
Pull request description:
Alright alright alright, I know: we hate refactors. We especially hate cosmetic refactors.
Nobody knows better than I that changing broad swaths of code out from under our already-abused collaborators, only to send a cascade of rebase bankruptcies, is annoying at best and sadistic at worst. And for a rename! The indignation!
But just for a second, imagine yourself. Programming `bitcoin/bitcoin`, on a sandy beach beneath a lapis lazuli sky. You go to type the name of what is probably the most commonly used data structure in the codebase, and you *only hit shift once*.
What could you do in such a world? You could do anything. [The only limit is yourself.](https://zombo.com/)

So maybe you like the idea of this patch but really don't want to deal with rebasing. You're in luck!
Here're the commands that will bail you out of rebase bankruptcy:
```sh
git rebase -i $(git merge-base HEAD master) \
-x 'sed -i "s/CChainState/Chainstate/g" $(git ls-files | grep -E ".*\.(py|cpp|h)$") && git commit --amend --no-edit'
# <commit changed?>
git add -u && git rebase --continue
```

~~Anyway I'm not sure how serious I am about this, but I figured it was worth proposing.~~ I have decided I am very serious about this.

2d0b4e4ff6 init: allow startup with -onlynet=onion -listenonion=1 (Vasil Dimov)
Pull request description:
It does not make sense to specify `-onlynet=onion` without providing a
Tor proxy (even if other `-onlynet=...` are given). This is checked
during startup. However, it was forgotten that a Tor proxy can also be
retrieved from "Tor control" to which we connect if `-listenonion=1`.
So, the full Tor proxy retrieval logic is:
1. get it from `-onion`
2. get it from `-proxy`
3. if `-listenonion=1`, then connect to "Tor control" and get the proxy
from there (was forgotten before this change)

2ef33e936e contrib: update testnet torv3 hardcoded seeds (Jon Atack)
Pull request description:
As a follow-up to https://github.com/bitcoin/bitcoin/issues/13550 and #22060, replace the mostly unreachable testnet torv3 hardcoded seeds from v0.22 with new ones that are consistently reachable recently and that have service bit 1 set.
This needs to be done before v24.0 to make sure onion-only testnet nodes can still connect to the network.
Ways to test:
- Re-generate `src/chainparamsseeds.h` with `cd contrib/seeds && python3 generate-seeds.py . > ../../src/chainparamsseeds.h`, check if git tree stays the same
- Re-compile and create a new testnet node with `bitcoind -testnet -dnsseed=0 -onlynet=onion -proxy=127.0.0.1:9050` (or delete `~/.bitcoin/testnet3/peers.dat` and launch bitcoind with `-testnet -dnsseed=0`). Make sure there are no `addnode=` in your `bitcoin.conf`. The debug log should print "Adding fixed seeds". Check if the node is able to connect to the network and get blocks with for ex. `watch -t ./src/bitcoin-cli -testnet -rpcwait -netinfo 4`
- Check the addrman contains the seeds by running for ex. `bitcoin-cli -rpcwait -testnet getnodeaddresses 0 onion | jq -r '.[] | (.address + ":" + (.port|tostring) + " " + (.services|tostring))' | sort`
- Check if the addresses are connectable, for ex. with this python script by laanwj:
```python3
#!/usr/bin/env python3
import pprint
import subprocess
with open('contrib/seeds/nodes_test.txt') as f:
for line in (line for line in (line.rstrip().split('#', 1)[0] for line in f) if line):
pprint.pprint(line)
subprocess.call(["nc", "-v", "-x", "127.0.0.1:9050", "-z"] + line.split(':'))
```

385f5a4c3f p2p: Don't query DNS seeds when both IPv4 and IPv6 are unreachable (Martin Zumsande)
91f0a7fbb7 p2p: add only reachable addresses to addrman (Martin Zumsande)
Pull request description:
Currently, `-onlynet` does not work well in connection with initial peer discovery, because DNS seeds only resolve to IPv6 and IPv4 adresses:
With `-onlynet=i2p`, we would load clearnet addresses from DNS seeds into addrman, be content our addrman isn't empty so we don't try to query hardcoded seeds (although these exist for i2p!), and never attempt to make an automatic outbound connection.
With `-onlynet=onion` and `-proxy` set, we wouldn't load addresses via DNS, but will make AddrFetch connections (through a tor exit node) to a random clearnet peer the DNS seed resolves to (see https://github.com/bitcoin/bitcoin/issues/6808#issuecomment-147652505), thus breaching the `-onlynet` preference of the user - this has been reported in the two issues listed below.
This PR proposes two changes:
1.) Don't load addresses that are unreachable (so that we wouldn't connect to them) into addrman. This is already the case for addresses received via p2p addr messages, this PR implements the same for addresses received from DNS seeds and fixed seeds. This means that in the case of `-onlynet=onion`, we wouldn't load fixed seed IPv4 addresses into addrman, only the onion ones.
2.) Skip trying the DNS seeds if neither IPv4 nor IPv6 are reachable and move directly to adding the hardcoded seeds from networks we can connect to. This is done by soft-setting `-dnsseed` to 0 in this case, unless `-dnsseed=1` was explicitly specified, in which case we abort with an `InitError`.

This happens, for example, if the user specified -onlynet=onion or
-onlynet=i2p. DNS seeds only resolve to IPv4 / IPv6 addresses,
making their answers useless to us, since we don't want to make
connections to these.
If, within the DNS seed thread, we'd instead do fallback AddrFetch
connections to one of the clearnet addresses the DNS seed resolves to,
we might get usable addresses from other networks
if lucky, but would be violating our -onlynet user preference
in doing so.
Therefore, in this case it is better to rely on fixed seeds for networks we
want to connect to.
Co-authored-by: Vasil Dimov <vd@FreeBSD.org>
We will not make outgoing connection to peers that are unreachable
(e.g. because of -onlynet configuration).
Therefore, it makes no sense to add them to addrman in the first place.
While this is already the case for addresses received via p2p addr
messages, this commit does the same for addresses received
from fixed seeds.
