91d93aac4e validation: remove nchaintx from assumeutxo metadata (James O'Beirne)
931684b24a validation: fix ActivateSnapshot to use hardcoded nChainTx (James O'Beirne)
Pull request description:
This fixes an oversight from the move of nChainTx from the user-supplied
snapshot metadata into the hardcoded assumeutxo chainparams.
Since the nChainTx is now unused in the metadata, it should be removed
in a future commit.

46b025e00d test: add new python linter to check file names and permissions (windsok)
6f6bb3ebc7 test: fix file permissions on various scripts (windsok)
Pull request description:
Adds a new python linter test which tests for correct filenames and file permissions in the repository.
Replaces the existing tests in the `test/lint/lint-filenames.sh` and `test/lint/lint-shebang.sh` linter tests, as well as adding some new and increased testing. This increased coverage is intended to catch issues such as in #21728 and https://github.com/bitcoin/bitcoin/pull/16807/files#r345547050
Summary of tests:
* Checks every file in the repository against an allowed regexp to make sure only lowercase or uppercase alphanumerics (a-zA-Z0-9), underscores (_), hyphens (-), at (@) and dots (.) are used in repository filenames.
* Checks only source files (*.cpp, *.h, *.py, *.sh) against a stricter allowed regexp to make sure only lowercase alphanumerics (a-z0-9), underscores (_), hyphens (-) and dots (.) are used in source code filenames. Additionally there is an exception regexp for directories or files which are excepted from matching this regexp (This should replicate the existing `test/lint/lint-filenames.sh` test)
* Checks all files in the repository match an allowed executable or non-executable file permission octal. Additionally checks that for executable files, the file contains a shebang line.
* Checks that for executable `.py` and `.sh` files, the shebang line used matches an allowable list of shebangs (This should replicate the existing `test/lint/lint-shebang.sh` test)
* Checks every file that contains a shebang line to ensure it has an executable permission
Additionally updates the permissions on various files to comply with the new tests.

Pull request description:
This is part of the coinstats index project tracked in #18000
While the review of the new UTXO set hash algorithm (MuHash) takes longer recently #19328 was merged which added the possibility to run `gettxoutsetinfo` with a specific hash type. As the first type it added `hash_type=none` which skips the hashing of the UTXO set altogether. This alone did not make `gettxoutsetinfo` much faster but it allows the use of an index for the remaining coin statistics even before a new hashing algorithm has been added. Credit to Sjors for the idea to take this intermediate step.
Features summary:
- Users can start their node with the option `-coinstatsindex` which syncs the index in the background
- After the index is synced the user can use `gettxoutsetinfo` with `hash_type=none` or `hash_type=muhash` and will get the response instantly out of the index
- The user can specify a height or block hash when calling `gettxoutsetinfo` to see coin statistics at a specific block height

Pull request description:
This PR is part of the [process separation project](https://github.com/bitcoin/bitcoin/projects/10).
---
This PR adds basic process spawning and IPC method call support to `bitcoin-node` executables built with `--enable-multiprocess`[*].
These changes are used in https://github.com/bitcoin/bitcoin/pull/10102 to let node, gui, and wallet functionality run in different processes, and extended in https://github.com/bitcoin/bitcoin/pull/19460 and https://github.com/bitcoin/bitcoin/pull/19461 after that to allow gui and wallet processes to be started and stopped independently and connect to the node over a socket.
These changes can also be used to implement new functionality outside the `bitcoin-node` process like external indexes or pluggable transports (https://github.com/bitcoin/bitcoin/pull/18988). The `Ipc::spawnProcess` and `Ipc::serveProcess` methods added here are entry points for spawning a child process and serving a parent process, and being able to make bidirectional, multithreaded method calls between the processes. A simple example of this is implemented in commit "Add echoipc RPC method and test."
Changes in this PR aside from the echo test were originally part of #10102, but have been split and moved here for easier review, and so they can be used for other applications like external plugins.
Additional notes about this PR can be found at https://bitcoincore.reviews/19160
[*] Note: the `--enable-multiprocess` feature is still experimental, and not enabled by default, and not yet supported on windows. More information can be found in [doc/multiprocess.md](https://github.com/bitcoin/bitcoin/blob/master/doc/multiprocess.md)

d831e711ca [validation] RewindBlockIndex no longer needed (Dhruv Mehta)
Pull request description:
Closes#17862
Context from [original comment](https://github.com/bitcoin/bitcoin/issues/17862#issuecomment-744285188) (minor edits):
`RewindBlockIndex()` is a mechanism to allow nodes to be upgraded after segwit activation, while still keeping their chainstate/datadir in a consistent state. It works as follows:
- A pre-segwit (i.e. v0.13.0 or older) node is running.
- Segwit activates. The pre-segwit node remains sync'ed to the tip, but is not enforcing the new segwit rules.
- The user upgrades the node to a segwit-aware version (v0.13.1 or newer).
- On startup, in `AppInitMain()`, `RewindBlockIndex()` is called. This walks the chain backwards from the tip, disconnecting and erasing blocks that from after segwit activation that weren't validated with segwit rules.
- those blocks are then redownloaded (with witness data) and validated with segwit rules.
This logic probably isn't required any more since:
- Segwit activated at height 481824, when the block chain was 130GB and the total number of txs was 250 million. Today, we're at height 667704, the blockchain is over 315GB and the total number of txs is over 600 million. Even if 20% of that added data is witness data (a high estimate), then around 150GB of transactions would need to be rewound to get back to segwit activation height. It'd probably be faster to simply validate from genesis, especially since we won't be validating any scripts before the assumevalid block. It's also unclear whether rewinding 150GB of transactions would even work. It's certainly never been tested.
- Bitcoin Core v0.13 is hardly used any more. https://luke.dashjr.org/programs/bitcoin/files/charts/software.html shows less than 50 nodes running it. The software was EOL on Aug 1st 2018. It's very unlikely that anyone is running 0.13 and will want to upgrade to 0.22.
This PR introduces `NeedsRedownload()` which merely checks for insufficiently validated segwit blocks and requests that the user restarts the node with `-reindex`. Reindexing the block files upon restart will make the node rebuild chain state and block index from the `blk*.dat` files on disk. The node won't be able to index the blocks with `BLOCK_OPT_WITNESS`, so they will be missing from the chain and be re-downloaded, with witness data.
Removing this code allows the following (done in follow-up #21090):
- removal of tests using `segwitheight=-1` in `p2p_segwit.py`.
- in turn, that allows us to drop support for `-segwitheight=-1`, which is only supported for that test.
- that allows us to always set `NODE_WITNESS` in our local services. The only reason we don't do that is to support `-segwitheight=-1`.
- that in turn allows us to drop all of the `GetLocalServices() & NODE_WITNESS` checks inside `net_processing.cpp`, since our local services would always include `NODE_WITNESS`

ce994e1202 test: add tx modfication helper function in feature_cltv.py (Sebastian Falbesoner)
Pull request description:
The functional test for [BIP65](https://github.com/bitcoin/bips/blob/master/bip-0065.mediawiki) / `OP_CHECKLOCKTIMEVERIFY` (`feature_cltv.py`) currently only tests one out of five conditions that lead to failure of the op-code -- by prepending the script `OP_1NEGATE OP_CHECKLOCKTIMEVERIFY OP_DROP` to a tx's first input's scriptSig, the case of "_the top item on the stack is less than 0_" is checked:
f8462a6d27/test/functional/feature_cltv.py (L26-L35)
This PR adds the other cases (5 in total) by taking an integer argument to the function `cltv_invalidate` that is called in a loop instead of only once per testing scenario. Here is the full list of failure conditions and how they are tested (note that the scriptSig should still be valid before activation of BIP65, when `OP_CLTV` is simply a no-op):
* _the stack is empty_
➡️ prepending `OP_CHECKLOCKTIMEVERIFY` to scriptSig
* _the top item on the stack is less than 0_
➡️ prepending `OP_1NEGATE OP_CHECKLOCKTIMEVERIFY OP_DROP` to scriptSig
* _the lock-time type (height vs. timestamp) of the top stack item and the nLockTime field are not the same_
➡️ prepending `OPNum(1000) OP_CHECKLOCKTIMEVERIFY OP_DROP` to scriptSig
➡️ setting tx.vin[0].nSequence=0 and tx.nCheckTimeLock=1296688602 (genesis block timestamp)
* _the top stack item is greater than the transaction's nLockTime field_
➡️ prepending `OPNum(1000) OP_CHECKLOCKTIMEVERIFY OP_DROP` to scriptSig
➡️ setting tx.vin[0].nSequence=0 and tx.nCheckTimeLock=500
* _the nSequence field of the txin is 0xffffffff_
➡️ prepending `OPNum(500) OP_CHECKLOCKTIMEVERIFY OP_DROP` to scriptSig
➡️ setting tx.vin[0].nSequence=0xffffffff and tx.nCheckTimeLock=500
The first commit creates a helper function for the tx modification and also includes some tidying up like turning single-line to multi-line Python imports where necessary and cleaning up some PEP8 warnings. The second commit prepares the invalidation function `cltv_invalidate` and the third and the fourth use it and check for the expected reject reason strings ("Operation not valid with the current stack size", "Negative locktime" and "Locktime requirement not satisfied").

This syncing behavior is necessary for normal operation as it helps guarantee that data won't become lost or corrupted, but in tests, we don't care about that.

Pull request description:
This picks up the closed pull request #21030 and is the first step toward fixing #21220.
The basic idea is to move all disk access into a separate module with benefits:
* Breaking down the massive files init.cpp and validation.cpp into logical units
* Creating a standalone-module to reduce the mental complexity
* Pave the way to fix validation related circular dependencies
* Pave the way to mock disk access for testing, especially where it is performance critical (like fuzzing)

This commit moves the ExternalSigner class and RPC methods out of the wallet module.
The enumeratesigners RPC can be used without a wallet since #21417.
With additional modifications external signers could be used without a wallet in general, e.g. via signrawtransaction.
The signerdisplayaddress RPC is ranamed to walletdisplayaddress because it requires wallet context.
A future displayaddress RPC call without wallet context could take a descriptor argument.
This commit fixes a rpc_help.py failure when configured with --disable-wallet.

3bb6e7b655 rpc: add network field to rpc getnodeaddresses (Jon Atack)
Pull request description:
This patch adds a network field to RPC `getnodeaddresses`, which is useful on its own, particularly with the addition of new networks like I2P and others in the future, and which I also found helpful for adding a new CLI command as a follow-up to this pull that calls `getnodeaddresses` and needs to know the network of each address.
While here, also improve the `getnodeaddresses` code and help.

Return known addresses, which can potentially be used to find new nodes in the network.
Arguments:
1. count (numeric, optional, default=1) The maximum number of addresses to return. Specify 0 to return all known addresses.

Future idea: allow passing `getnodeaddresses` a network (or networks) as an argument to return only addresses in that network.

6965456c10 Introduce DeferringSignatureChecker and inherit with SignatureExtractor (Andrew Chow)
Pull request description:
Previously SignatureExtractorChecker took a MutableTransactionSignatureChecker and passed through function calls to that. However not all functions were implemented so not everything passed through as it should have. To solve this, SignatureExctractorChecker now implements all of those functions via a new class - DeferredSignatureChecker. DeferredSignatureChecker is introduced to allow for future signature checkers which use another SignatureChecker but need to be able to do somethings outside of just the signature checking.

90ae3d8ca6 doc: Add release notes for -deprecatedrpc=addresses and bitcoin-tx (Michael Dietz)
085b3a7299 rpc: deprecate `addresses` and `reqSigs` from rpc outputs (Michael Dietz)
Pull request description:
Considering the limited applicability of `reqSigs` and the confusing output of `1` in all cases except bare multisig, the `addresses` and `reqSigs` outputs are removed for all rpc commands.
1) add a new sane "address" field (for outputs that have an identifiable address, which doesn't include bare multisig)
2) with -deprecatedrpc: leave "reqSigs" and "addresses" intact (with all weird/wrong behavior they have now)
3) without -deprecatedrpc: drop "reqSigs" and "addresses" entirely always.
Note: Some light refactoring done to allow us to very easily delete a few chunks of code (marked with TODOs) when we remove this deprecated behavior.
Using `IsDeprecatedRPCEnabled` in core_write.cpp caused some circular dependencies involving core_io
Circular dependencies were caused by rpc/util unnecessarily importing node/coinstats and node/transaction. Really what rpc/util needs are some fundamental type/helper-function definitions. So this was cleaned up to make more sense.
This fixes#20102.

beead33a21 [test] no send feefilters when txrelay is turned off (glozow)
18a9b27dd6 p2p: Don't send FEEFILTER in blocksonly mode (Martin Zumsande)
Pull request description:
The purpose of FEEFILTER messages (BIP 133) is to inform our peers that we do not want transactions below a specified fee rate.
In blocksonly mode, we do not want our peer to send us any transactions at all (and will disconnect if a peer still sends a transaction INV or TX).
Therefore, I don't think that it makes sense to send FEEFILTER messages every 10 minutes on average in blocksonly mode - this PR disables it.
Note that on block-relay-only connections, FEEFILTER is already disabled, just not in blocksonly mode.

39a9ec579f Unconditionally check for fRelay field in test framework (Troy Giorshev)
Pull request description:
picking up #20411 (rebased onto master)
There is a discrepancy in the implementation of our p2p protocol between
bitcoind and the testing framework. The fRelay field is an optional
field at the end of a version message as of protocol version 70001.
However, when deserializing a message in bitcoind, we don't check the
version to see if it should have an fRelay field or not. Instead, we
unconditionally attempt to deserialize into the field.
This commit brings the testing framework in line with the implementation
in core.
This matters for a version message with the following fields:
Version = 60000
fRelay = 1
Bitcoind would deserialize this into a version message with
Version=60000 and fRelay=1, whereas (before this commit) our testing
framework would deserialize this into a version message with
Version=60000 and fRelay=0.

3e69939b78 Fail if maximum weight is too large (Andrew Chow)
51e2cd322c Have CalculateMaximumSignedTxSize also compute tx weight (Andrew Chow)
Pull request description:
Currently the `Transaction too large` is calculated on the transaction that is returned from `CreateTransaction`. This does not make sense for when `CreateTransaction` is being used for `fundrawtransaction` as no signing occurs so the final returned transaction is missing signatures. Thus users may successfully fund a transaction but fail to broadcast it after it has been fully signed.
So instead we should figure out whether the transaction we are funding will be too large after it is signed. We can do this by having `CalculateMaximumSignedTxSize` also return the transaction weight and then comparing that weight against the maximum weight.

Pull request description:
Add I2P support by using the [I2P SAM](https://geti2p.net/en/docs/api/samv3) protocol. Unlike Tor, for incoming connections we get the I2P address of the peer (and they also receive ours when we are the connection initiator).
Two new options are added:
```
-i2psam=<ip:port>
I2P SAM proxy to reach I2P peers and accept I2P connections (default:
none)
-i2pacceptincoming
If set and -i2psam is also set then incoming I2P connections are
accepted via the SAM proxy. If this is not set but -i2psam is set
then only outgoing connections will be made to the I2P network.
Ignored if -i2psam is not set. Notice that listening for incoming
I2P connections is done through the SAM proxy, not by binding to
a local address and port (default: true)
```
# Overview of the changes
## Make `ReadBinary()` and `WriteBinary()` reusable
We would need to dump the I2P private key to a file and read it back later. Move those two functions out of `torcontrol.cpp`.
```
util: extract {Read,Write}BinaryFile() to its own files
util: fix ReadBinaryFile() returning partial contents
util: fix WriteBinaryFile() claiming success even if error occurred
```
## Split `CConnman::AcceptConnection()`
Most of `CConnman::AcceptConnection()` is agnostic of how the socket was accepted. The other part of it deals with the details of the `accept(2)` system call. Split those so that the protocol-agnostic part can be reused if we accept a socket by other means.
```
net: check for invalid socket earlier in CConnman::AcceptConnection()
net: get the bind address earlier in CConnman::AcceptConnection()
net: isolate the protocol-agnostic part of CConnman::AcceptConnection()
net: avoid unnecessary GetBindAddress() call
```
## Implement the I2P [SAM](https://geti2p.net/en/docs/api/samv3) protocol (not all of it)
Just the parts that would enable us to make outgoing and accept incoming I2P connections.
```
net: extend CNetAddr::SetSpecial() to support I2P
net: move the constant maxWait out of InterruptibleRecv()
net: dedup MSG_NOSIGNAL and MSG_DONTWAIT definitions
net: extend Sock::Wait() to report a timeout
net: extend Sock with methods for robust send & read until terminator
net: extend Sock with a method to check whether connected
net: implement the necessary parts of the I2P SAM protocol
```
## Use I2P SAM to connect to and accept connections from I2P peers
Profit from all of the preceding commits.
```
init: introduce I2P connectivity options
net: add I2P to the reachability map
net: make outgoing I2P connections from CConnman
net: accept incoming I2P connections from CConnman
net: recognize I2P from ParseNetwork() so that -onlynet=i2p works

8a8c6383f6 zmq test: fix sync-up by matching notification to generated block (Sebastian Falbesoner)
Pull request description:
This is a follow-up PR for #21008, fixes#21216.
In the course of investigating the problem with jnewbery (analyzing the Cirrus log https://cirrus-ci.com/task/4660108304056320), it turned out that the "sync up" procedure of repeatedly generating a block and waiting for a notification with timeout is too brittle in its current form, as the following scenario could happen:
- generate block A
- receive notification, timeout happens => repeat procedure
- generate block B
- node publishes block A notification
- receive notification, we receive the one caused by block A (!!!) => sync-up procedure is completed
- node publishes block B notification
- the actual test starts
- on the first notification reception, the one caused by block B is received, rather than the one actually caused by test code => assertion failure
This change in the PR ensures that after each test block generation, we wait for the notification that is actually caused by that block and ignore others from possibly earlier blocks. The matching is kind of ugly, it assumes that one out of four components in the block is contained in the notification: the block hash, the tx id, the raw block data or the raw transaction data. (Unfortunately we have to support all publisher topics.)
I'm aware that this is quite a lot of code now only for establishing a robust test setup. OTOH I wouldn't know of a better method right now, suggestions are very welcome.
Note for potential reviewers: for both reproducing the issue on master branch and verifying on PR branch, one can simply generate two blocks in the sync-up procedure rather than one.

Co-authored-by: Jon Atack <jon@atack.com>
Introduce two new options to reach the I2P network:
* `-i2psam=<ip:port>` point to the I2P SAM proxy. If this is set then
the I2P network is considered reachable and we can make outgoing
connections to I2P peers via that proxy. We listen for and accept
incoming connections from I2P peers if the below is set in addition to
`-i2psam=<ip:port>`
* `-i2pacceptincoming` if this is set together with `-i2psam=<ip:port>`
then we accept incoming I2P connections via the I2P SAM proxy.
It turned out that the "sync up" procedure of repeatedly generating a
block and waiting for a notification once with timeout is too naive in
its current form, as the following scenario could happen:
- generate block A
- receive notification, timeout happens -> repeat procedure
- generate block B
- node publishes block A notification
- receive notification, we receive the one caused by block A
-> sync-up procedure is completed
- node publishes block B
- the actual test starts
- on the first notification reception, one caused by block B is received,
rather than the one actually caused by test code, leading to failure
This change ensures that after each test block generation, we wait for
the notification that is actually caused by that block and ignore others
from possibly earlier blocks.

This option replaces --with-boost-process
This prepares external signer support to be disabled by default.
It adds a configure option to enable this feature and to check
if Boost::Process is present.
This also exposes ENABLE_EXTERNAL_SIGNER to the test suite via test/config.ini
Every (sub)test in the framework assumes the node is running, except for
the (sub)tests in this file. Remove that confusion by stopping the node
at the start of every subtest, instead of at the end.

Pull request description:
Prefix log messages with function name if `-logfunctionnames` is set.
Yes, exactly like `-logthreadnames` but for function names instead of thread names :)
This is a small developer ergonomics improvement: I've found this to be a cheap/simple way to correlate log output and originating function.
For me it beats the ordinary cycle of 1.) try to figure out a regexp matching the static part of the dynamic log message, 2.) `git grep -E 'Using .* MiB out of .* requested for signature cache'`, 3.) `mcedit filename.cpp` (`openemacs filename.cpp` works too!) and 4.) search for log message and scroll up to find the function name :)

It also changes the SUBVERSION constant to be a string instead of a bytes object. That means that it needs to be explicitly converted to a bytes object to serialize into a version message. Failing to do so would cause an easy-to-spot bug. This should avoid silent failures like the one solved in #20522.

Pull request description:
Adds `parent_desc` field to the `getaddressinfo` RPC to export a public descriptor. Using the given address, `getaddressinfo` will look up which `DescriptorScriptPubKeyMan` can be used to produce that address. It will then return the descriptor for that `DescriptorScriptPubKeyMan` in the `parent_desc` field. The descriptor will be in a normalized form where the xpub at the last hardened step is derived so that the descriptor can be imported to other wallets. Tests are added to check that the correct descriptor is being returned for the wallet's addresses and that these descriptors can be imported and used in other wallets.
As part of this PR, a `ToNormalizedString` function is added to the descriptor classes. This really only has an effect on `BIP32PubkeyProvider`s that have hardened derivation steps. Tests are added to check that normalized descriptors are returned.

other versioning used in Bitcoin/Bitcoin Core.
Also always set the nVersion field in CBlockLocator to 0 and ignore the
field in deserialized messages. The field is not currently used for
anything in Bitcoin Core.
The messages.py module should contain code and helpers for
[de]serializing p2p messages. Specific usage of those messages should
be in p2p.py. Therefore move MIN_VERSION_SUPPORTED to p2p.py.
Also rename to MIN_P2P_VERSION_SUPPORTED to distinguish it from

de85af5cce test: store subversion (user agent) as string in msg_version (Sebastian Falbesoner)
Pull request description:
It seems more natural to treat the "subversion" field (=user agent string, see [BIP 14](https://github.com/bitcoin/bips/blob/master/bip-0014.mediawiki#Proposal)) of a node as pure string rather than a bytestring within the test framework. This is also suggested with the naming prefix in `msg_version.strSubVer`: one probably wouldn't expect a field starting with "str" to be a bytestring that needs further decoding to be useful. This PR moves the encoding/decoding parts to the serialization/deserialization routines so that the user doesn't have to bother with that anymore.
Note that currently, in the master branch the `msg_version.strSubVer` is never read (only in `msg_version.__repr__`); However, one issue that is solved by this PR came up while testing #19509 (not merged yet): A decoding script for binary message capture files takes use of the functional test framework convert it into JSON format. Bytestrings will be convered to hexstrings, while pure strings will (surprise surprise) end up without modification in the file.
So without this patch, we get:
```
$ jq . out.json | grep -m5 strSubVer
"strSubVer": "2f5361746f7368693a32312e39392e302f"

"strSubVer": "2f5361746f7368693a32312e39392e302f"
```
After this patch:
```
$ jq . out2.json | grep -m5 strSubVer
"strSubVer": "/Satoshi:21.99.0/"
"strSubVer": "/Satoshi:0.20.1/"
"strSubVer": "/Satoshi:21.99.0/"

Pull request description:
This is part of the [assumeutxo project](https://github.com/bitcoin/bitcoin/projects/11):
Parent PR: #15606
Issue: #15605
Specification: https://github.com/jamesob/assumeutxo-docs/tree/master/proposal
---
This change proposes logic for activating UTXO snapshots, which is unused at the moment aside from an included unittest. There are a few moveonyish/refactoring commits to allow for halfway decent unittests.
Basic structure is included for specifying and checking the assumeutxo hash values used to validate activated snapshots. Initially I had specified a few height/hash pairs for mainnet in this change, but because of the security-critical nature of those parameters, I figured it was better to leave their inclusion to a future PR that includes only that change - my intent being that reviewers will be more likely to verify those parameters firsthand in a dedicated PR.
Aside from that and the snapshot activation logic, there are a few related changes:
- ~~allow caching the `nChainTx` value in the CCoinsViewDB; this is set during snapshot activation. Because we don't necessarily have access to the full chain at the time of snapshot load, this value is communicated through the snapshot metadata and must be cached within the chainstate to survive restarts.~~
- break out `CreateUTXOSnapshot()` from dumptxoutset. This is essentially a move-only change to allow the reuse of snapshot creation logic from within unittests.
- ...and a few other misc. changes that are solely related to unittests.
The move-onlyish commit is most easily reviewed with `--color-moved=zebra`.

Pull request description:
Fixes#20934 by using the "sync up" method described in https://github.com/bitcoin/bitcoin/issues/20538#issuecomment-738791868.
After improving robustness with this approach (commits 1-3), it turned out that there were still some fails, but those were unrelated to zmq: Out of 500 runs, 3 times `sync_mempool()` or `sync_blocks()` timed out, which can happen because the trickle relay time has no upper bound -- hence in rare cases, it takes longer than 60s. This is fixed by enabling immediate tx relay on node1 (commit 4), which as a nice side-effect also gives us a rough 2x speedup for the test.
For further details, also see the explanations in the commit messages.
There is no guarantee that the test is still not flaky, but it would help if potential reviewers would run the following script locally and report how many runs failed (feel free to do less than 1000 runs, as this takes quite a long if ran with `--valgrind`):
```
#!/bin/sh
OUTPUT_FILE=./zmq_results
echo ===== repeated zmq test ===== > $OUTPUT_FILE
for i in `seq 1000`; do
echo ------------------------
echo ----- test run $i -----
echo ------------------------
echo --- $i --- >> $OUTPUT_FILE
./test/functional/interface_zmq.py --valgrind
if [ $? -ne 0 ]; then
echo "FAILED. /o\\" >> $OUTPUT_FILE
else
echo "PASSED. \\o/" >> $OUTPUT_FILE
fi
done
echo Failed test runs:

3f8776a139 Re-add dead code detection (flack)
Pull request description:
This re-adds unreachable code detection for Python based on `vulture`.
Effectively, this reverts f4beb4996d. The difference to the previous version is that this runs with the `--min-confidence 100` setting. From https://pypi.org/project/vulture/:
> Use `--min-confidence 100` to only report code that is guaranteed to be unused within the analyzed files.
So this should avoid the previous issues where static analysis had wrong positives due to the dynamic nature of Python code by only reporting things that are unambiguous (such as code after a `return` statement). As such, there is not suppressions list.
My motivation was mainly #21081 which would have been caught by this (as can be seen by the CI run failing). This is still marked as draft because #21081 is needed to get the linter to pass. Also, there is a second problem that this found (see https://github.com/bitcoin/bitcoin/pull/19509/files#r571454691). From what I can tell, this is a spurious type comment that could just be removed (or if that line has no side effects it could also be deleted altogether?). I could add a commit here to fix it, but I wanted to see if there is interest in having this linter again in the first place

f64adc1eed test: remove unused function xor_bytes (Sebastian Falbesoner)
Pull request description:
The function `xor_bytes` was introduced in commit 3c226639eb (#19953, BIP340-342 validation), even [code-reviewed](https://github.com/bitcoin/bitcoin/pull/19953/files#r509383731), but actually never used. The [default signing algorithm in BIP340](https://github.com/bitcoin/bips/blob/master/bip-0340.mediawiki#Default_Signing) needs a xor operation, but this step is currently done by a single xor operation on large integer operands:
```
t = (sec ^ int.from_bytes(TaggedHash("BIP0340/aux", aux), 'big')).to_bytes(32, 'big')
```
Alternatively, we could keep the function and as well use it:

fe3e993968 [p2p] No delay in adding fixed seeds if -dnsseed=0 and peers.dat is empty. Add -fixedseeds arg. (Dhruv Mehta)
Pull request description:
Closes#19795
Before PR: If `peers.dat` is empty and `-dnsseed=0`, bitcoind will fallback on to fixed seeds but only after a 60 seconds delay.
After PR: There's no 60 second delay.
To reproduce:
`rm ~/.bitcoin/peers.dat && src/bitcoind -dnsseed=0` without and with patch code
Other changes in the PR:
- `-fixedseeds` command line argument added: `-dnsseed=0 -fixedseeds=0 -addnode=X` provides a trusted peer only setup. `-dnsseed=0 -fixedseeds=0` allows for a `addnode` RPC to add a trusted peer without falling back to hardcoded seeds.

Pull request description:
This replaces `boost::shared_mutex` and `boost::unique_lock` with [`std::shared_mutex`](https://en.cppreference.com/w/cpp/thread/shared_mutex) & [`std::unique_lock`](https://en.cppreference.com/w/cpp/thread/unique_lock).
Even though [some concerns were raised](https://github.com/bitcoin/bitcoin/issues/16684#issuecomment-726214696) in #16684 with regard to `std::shared_mutex` being unsafe to use across some glibc versions, I still think this change is an improvement. As I mentioned in #21022, I also think trying to restrict standard library feature usage based on bugs in glibc is not only hard to do, but it's not currently clear exactly how we do that in practice (does it also extend to patching out use in our dependencies, should we be implementing more runtime checks for features we are using, when do we consider an affected glibc "old enough" not to worry about? etc). If you take a look through the [glibc bug tracker](https://sourceware.org/bugzilla/describecomponents.cgi?product=glibc) you'll no doubt find plenty of (active) bug reports for standard library code we already using. Obviously not to say we shouldn't try and avoid buggy code where possible.
Two other points:
[Cory mentioned in #21022](https://github.com/bitcoin/bitcoin/pull/21022#issuecomment-769274179):
> It also seems reasonable to me to worry that boost hits the same underlying glibc bug, and we've just not happened to trigger the right conditions yet.
Moving away from Boost to the standard library also removes the potential for differences related to Boosts configuration. Boost has multiple versions of `shared_mutex`, and what you end up using, and what it's backed by depends on:
* The version of Boost.
* The platform you're building for.
* Which version of `BOOST_THREAD_VERSION` is defined: (2,3,4 or 5) default=2. (see [here](https://www.boost.org/doc/libs/1_70_0/doc/html/thread/build.html#thread.build.configuration) for some of the differences).
* Is `BOOST_THREAD_V2_SHARED_MUTEX` defined? (not by default). If so, you might get the ["less performant, but more robust"](https://github.com/boostorg/thread/issues/230#issuecomment-475937761) version of `shared_mutex`.
A lot of these factors are eliminated by our use of depends, but users will have varying configurations. It's also not inconceivable to think that a distro, or some package manager might start defining something like `BOOST_THREAD_VERSION=3`. Boost tried to change the default from 2 to 3 at one point.
With this change, we no longer use Boost Thread, so this PR also removes it from depends, the build system, CI etc.

Speeds up the zmq test roughly by a factor of 2x (~20 sec. instead of
~40 sec.) and also avoids timeouts on the synchronization methods
(sync_mempool() / sync_blocks()) that happened with a slight chance.
This is due to the fact that there is no upper bound on the trickle
relay time, so even the default of 60s is sometimes too low. Fixed by
enabling immediate tx relay on node1.
After connecting the subscriber sockets to the node, there is no
guarantee that the node's zmq publisher interfaces are ready yet, which
means that potentially the first expected notification messages could
get lost and the test fails. Currently this is handled by just waiting
for a short period of time (200ms), which works most of the time but is
still problematic, as in some rare cases the setup time takes much
longer, even in the range of multiple seconds.
The solution in this commit approaches the problem by using a more
robust method of syncing up, originally proposed by instagibbs:
1. Generate a block on the node
2. Try to receive a notification on all subscribers
3. If all subscribers get a message within the timeout (1 second),
we are done, otherwise repeat starting from step 1
The ZMQSubscriber reception methods currently assert that the first
received publisher message has a sequence number of zero. In order to
fix the current test flakiness via "syncing up" to nodes in the setup
phase, we have to cope with the situation that messages get lost and the
first actual received message has a sequence number larger than zero.
