This commit just moves functions without making any changes. It can be
reviewed with `git log -p -n1 --color-moved=dimmed_zebra`
Motivation for this change is to make wallet.cpp/h less monolithic and
start to make wallet transaction state tracking comprehensible so bugs
in
https://github.com/bitcoin-core/bitcoin-devwiki/wiki/Wallet-Transaction-Conflict-Tracking
can be fixed safely without introducing new problems.
This commit moves wallet classes and methods that deal with transactions
out of wallet.cpp/.h into better organized files:
- transaction.cpp/.h - CWalletTx and CMerkleTx class definitions
- receive.cpp/.h - functions checking received transactions and computing balances
- spend.cpp/.h - functions creating transactions and finding spendable coins
After #20773, when loading is separated from syncing it will also be
possible to move more wallet.cpp/.h functions to:
- sync.cpp/.h - functions handling chain notifications and rescanning
This commit arranges receive.cpp and spend.cpp functions in dependency
order so it's possible to skim receive.cpp and get an idea of how
computing balances works, and skim spend.cpp and get an idea of how
transactions are created, without having to jump all over wallet.cpp
where functions are not in order and there is a lot of unrelated code.
Followup commit "refactor: Detach wallet transaction methods" in
https://github.com/bitcoin/bitcoin/pull/21206 follows up this PR and
tweaks function names and arguments to reflect new locations. The two
commits are split into separate PRs because this commit is more work to
maintain and less work to review, while the other commit is less work to
maintain and more work to review, so hopefully this commit can be merged
earlier.
Define the Package type as an alias for a vector of transactions for now.
Add PackageValidationResult, similar to TxValidationResult and
BlockValidationResult for package-wide errors that cannot be reported
within a single transaction result, such as having too many
transactions in the package. We can update the concept of
what a package is and have different logic for packages vs lists of
transactions in the future, e.g. for package relay.

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

---
This change is move-only and can be easily reviewed with `--color-moved=dimmed_zebra`. The moves are needed to avoid duplicating common init code between different binaries (`bitcoin-node`, `bitcoin-wallet`, etc) in #10102. In #10102, each binary has it's own init file (`src/init/bitcoin-node.cpp`, `src/init/bitcoin-wallet.cpp`) so this PR moves the common code to `src/init/common.cpp`.

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)

b54b2e7b1a Move external signer out of wallet module (Sjors Provoost)
Pull request description:
In addition, this PR enables external signer testing on CI.
This PR 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`.

52f0be3a93 compat: remove memcpy -> memmove backwards compatibility alias (fanquake)
Pull request description:
In glib 2.13 memcpy was changed such that the way it copied bytes was reversed.
This caused all sorts of issues for existing software, which depended on the
existing behavior (when they should have been using memmove). See:
https://sourceware.org/bugzilla/show_bug.cgi?id=12518https://bugzilla.redhat.com/show_bug.cgi?id=638477
Now that we require glibc 2.17+ (#17538), we should be well clear of having to
maintain our memcpy -> memmove aliasing, which was introduced in #4339.

1a6323bdbe doc: update developer notes for removal of MakeUnique (fanquake)
3ba2840e7e scripted-diff: remove MakeUnique<T>() (fanquake)
Pull request description:
Since requiring C++17, this is just pointless abstraction. I think we should just "tear the band-aid off" and remove it. Similar to the changes happening in #21366.
Also, having a comment saying this is deprecated doesn't prevent it's usage in new code. i.e : https://github.com/bitcoin/bitcoin/pull/20946#discussion_r561949731.
The repository is fairly quiet at the moment, so any potential complaints about having to rebase should be minimal. Might as well get this over and done with.

e017a913d0 bitcoind: Add -daemonwait option to wait for initialization (Wladimir J. van der Laan)
c3e6fdee6d shutdown: Use RAII TokenPipe in shutdown (Wladimir J. van der Laan)
612f746a8f util: Add RAII TokenPipe (Wladimir J. van der Laan)
Pull request description:
This adds a `-daemonwait` flag that does the same as `-daemon` except that it, from a user perspective, backgrounds the process only after initialization is complete. This is similar to the behaviour of some other software such as c-lightning.
This can be useful when the process launching bitcoind wants to guarantee that either the RPC server is running, or that initialization failed, before continuing. The exit code indicates the initialization result.
The use of the libc function `daemon()` is replaced by a custom implementation which is inspired by the [glibc implementation](https://github.com/lattera/glibc/blob/master/misc/daemon.c#L44), but which also creates a pipe from the child to the parent process for communication.
An additional advantage of having our own `daemon()` implementation is that no MACOS-specific pragmas are needed anymore to silence a deprecation warning.
TODO:
- [x] Factor out `token_read` and `token_write` to an utility, and use them in `shutdown.cpp` as well—this is exactly the same kind of communication mechanism.
- [x] RAII-ify pipe endpoints.
- [x] Improve granularity of the `configure.ac` checks. This currently still checks for the function `daemon()` which makes no sense as it's not used. It should check for individual functions such as
`fork()` and `setsid()` etc—the former being required, the second optional.
- [-] ~~Signal propagation during initialization: if say, pressing Ctrl-C during `-daemonwait` it would be good to pass this SIGINT on to the child process instead of detaching the parent process and letting the child run free.~~ This is not necessary, see https://github.com/bitcoin/bitcoin/pull/21007#issuecomment-769007341.
Future:
- Consider if it makes sense to use this in the RPC tests (there would be no more need for "is RPC ready" polling loops). I think this is out of scope for this PR.

In glib 2.13 memcpy was changed such that the way it copied bytes was reversed.
This caused all sorts of issues for existing software, which depended on the
existing behavior (when they should have been using memmove). See:
https://sourceware.org/bugzilla/show_bug.cgi?id=12518https://bugzilla.redhat.com/show_bug.cgi?id=638477
Now that we require glibc 2.17+ (#17538), we should be well clear of having to
maintain our memcpy -> memmove aliasing, which was introduced in #4339.
7af25024e9 build: compile libnatpmp with -DNATPMP_STATICLIB on Windows (fanquake)
ee35745754 build: use newer source for libnatpmp (fanquake)
Pull request description:
The source we are currently using is from 2015. The upstream repo has
received a small number of bug fixes and improvements since then.
Including one that fixes an issue for Windows users: https://github.com/miniupnp/libnatpmp/pull/13.
The source we are currently using is the most recent "official" release,
however I don't think it's worth waiting for a new one. The maintainer
was prompted to do so in Oct 2020, then again in Jan of this year, and
no release has eventuated. Given libnatpmp is a new inclusion into our
repository, I think we should be using this newer source.
This also cleans up a few warnings we currently see in Windows depends builds:

fd6580e405 [refactor] txmempool: split epoch logic into class (Anthony Towns)

ACK fd6580e405 using clang thread safety annotations looks like a very good idea, and the encapsulation this change adds should improve robustness (and possible unit test-ability) of the code. Verified that changing some of the locking duly provoked build-time warnings with Clang 9 on Debian and that small changes in the new `Epoch` class were covered by failing functional test assertions in `mempool_updatefromblock.py`, `mempool_resurrect.py`, and `mempool_reorg.py`

7097add83c refactor: replace Boost shared_mutex with std shared_mutex in sigcache (fanquake)
8e55981ef8 refactor: replace Boost shared_mutex with std shared_mutex in cuckoocache tests (fanquake)
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.
Previous similar PRs were #19183 & #20922. The authors are included in the commits here.
Also related to #21022 - pthread sanity checking.

Pull request description:
Introduce a class to manage the lifetime of a socket - when the object
that contains the socket goes out of scope, the underlying socket will
be closed.
In addition, the new `Sock` class has a `Send()`, `Recv()` and `Wait()`
methods that can be overridden by unit tests to mock the socket
operations.
The `Wait()` method also hides the
`#ifdef USE_POLL poll() #else select() #endif` technique from higher
level code.

Move `CloseSocket()` (and `NetworkErrorString()` which it uses) from
`netbase.{h,cpp}` to newly added `src/util/sock.{h,cpp}`.
This is necessary in order to use `CloseSocket()` from a newly
introduced Sock class (which will live in `src/util/sock.{h,cpp}`).
`sock.{h,cpp}` cannot depend on netbase because netbase will depend
on it.
22eb7930a6 tracing: add tracing framework (William Casarin)
933ab8a720 build: detect sys/sdt.h for eBPF tracing (William Casarin)
Pull request description:
Instead of writing ad-hoc logging everywhere (eg: #19509), we can take advantage of linux user static defined traces, aka. USDTs ( not the stablecoin 😅 )
The linux kernel can hook into these tracepoints at runtime, but otherwise they have little to no performance impact. Traces can pass data which can be printed externally via tools such as bpftrace. For example, here's one that prints incoming and outgoing network messages:
# Examples
## Network Messages
```
#!/usr/bin/env bpftrace
BEGIN
{
printf("bitcoin net msgs\n");
@start = nsecs;
}
usdt:./src/bitcoind:net:push_message
{
$ip = str(arg0);
$peer_id = (int64)arg1;
$command = str(arg2);
$data_len = arg3;
$data = buf(arg3,arg4);
$t = (nsecs - @start) / 100000;
printf("%zu outbound %s %s %zu %d %r\n", $t, $command, $ip, $peer_id, $data_len, $data);
@outbound[$command]++;
}
usdt:./src/bitcoind:net:process_message
{
$ip = str(arg0);
$peer_id = (int64)arg1;
$command = str(arg2);
$data_len = arg3;
$data = buf(arg3,arg4);
$t = (nsecs - @start) / 100000;
printf("%zu inbound %s %s %zu %d %r\n", $t, $command, $ip, $peer_id, $data_len, $data);
@inbound[$ip, $command]++;
}
```
$ sudo bpftrace netmsg.bt
output: https://jb55.com/s/b11312484b601fb3.txt
if you look at the bottom of the output you can see a histogram of all the messages grouped by message type and IP. nice!
## IBD Benchmarking
```
#!/usr/bin/env bpftrace
BEGIN
{
printf("IBD to 500,000 bench\n");
}
usdt:./src/bitcoind:CChainState:ConnectBlock
{
$height = (uint32)arg0;
if ($height == 1) {
printf("block 1 found, starting benchmark\n");
@start = nsecs;
}
if ($height >= 500000) {
@end = nsecs;
@duration = @end - @start;
exit();
}
}
END {
printf("duration %d ms\n", @duration / 1000000)
}
```
This one hooks into ConnectBlock and prints the IBD time to height 500,000 starting from the first call to ConnectBlock
Userspace static tracepoints give lots of flexibility without invasive logging code. It's also more flexible than ad-hoc logging code, allowing you to instrument many different aspects of the system without having to enable per-subsystem logging.
Other ideas: tracepoints for lock contention, threads, what else?
Let me know what ya'll think and if this is worth adding to bitcoin.

634f6ec4eb contrib: Parse ELF directly for symbol and security checks (Wladimir J. van der Laan)
Pull request description:
Instead of the ever-messier text parsing of the output of the readelf tool (which is clearly meant for human consumption not to be machine parseable), parse the ELF binaries directly.
Add a small dependency-less ELF parser specific to the checks.
This is slightly more secure, too, because it removes potential ambiguity due to misparsing and changes in the output format of `elfread`. It also allows for stricter and more specific ELF format checks in the future.
This removes the build-time dependency for `readelf`.
It passes the test-security-check for me locally, ~~though I haven't checked on all platforms~~. I've checked that this works on the cross-compile output for all ELF platforms supported by Bitcoin Core at the moment, as well as PPC64 LE and BE.

Move `NodeImpl` from `interfaces/node.cpp` to `node/interfaces.cpp`
Move `ChainImpl` from `interfaces/chain.cpp` to `node/interfaces.cpp`
Move `WalletImpl` from `interfaces/wallet.cpp` to `wallet/interfaces.cpp`
No changes to any classes (can review with `git diff --color-moved=dimmed_zebra`)
Motivation for this change is to move node and wallet code to respective directories where it might fit in better than `src/interfaces/`, but also to remove all unnecessary code from `src/interfaces/` to unblock #19160 review, which has been hung up partially because of code organization. Building on top of this PR, #19160 should now be able to organize interface implementations more understandably in `src/node/` `src/wallet/` `src/ipc/` and `src/init/` directories instead of having so much functionality all in `src/interfaces/`

Pull request description:
This PR adds a new class `SQLiteDatabase` which is a subclass of `WalletDatabase`. This provides access to a SQLite database that is used to store the wallet records. To keep compatibility with BDB and to complexity of the change down, we don't make use of many SQLite's features. We use it strictly as a key-value store. We create a table `main` which has two columns, `key` and `value` both with the type `blob`.
For new descriptor wallets, we will create a `SQLiteDatabase` instead of a `BerkeleyDatabase`. There is no requirement that all SQLite wallets are descriptor wallets, nor is there a requirement that all descriptor wallets be SQLite wallets. This allows for existing descriptor wallets to work as well as keeping open the option to migrate existing wallets to SQLite.
We keep the name `wallet.dat` for SQLite wallets. We are able to determine which database type to use by searching for specific magic bytes in the `wallet.dat` file. SQLite begins it's files with a null terminated string `SQLite format 3`. BDB has `0x00053162` at byte 12 (note that the byte order of this integer depends on the system endianness). So when we see that there is a `wallet.dat` file that we want to open, we check for the magic bytes to determine which database system to use.
I decided to keep the `wallet.dat` naming to keep things like backup script to continue to function as they won't need to be modified to look for a different file name. It also simplifies a couple of things in the implementation and the tests as `wallet.dat` is something that is specifically being looked for. If we don't want this behavior, then I do have another branch which creates `wallet.sqlite` files instead, but I find that this direction is easier.

Code review ACK c4a29d0a90. I am honestly confused about reasons for locking into `wallet.dat` again when it's so easy now to use a clean format. I assume I'm just very dense, or there's some unstated reason, because the only thing that's been brought up are unrealistic compatibility scenarios (all require actively creating a wallet with non-default descriptor+sqlite option, then trying to using the descriptor+sqlite wallets with old software or scripts and ignoring the results) that we didn't pay attention to with previous PRs like #11687, which did not require any active interfaction.

Pull request description:
This contains various small code cleanups that make the ZMQ code easier to read and maintain (at least in my opinion). The only functional change is that a potential memory leak is fixed that would have occured when a notifier is removed from the `notifiers` list after its callback function returned `false` (which is likely not relevant in practice but still a bug).

Note that with this change we are no-longer including PTHREAD_* flags
when building libbitcoinconsensus.
Also note that we are including PTHREAD_LIBS in AM_PTHREAD_FLAGS
zmqconfig.h is currently not really needed anywhere, except that
it declares zmqError (which is then defined in
zmqnotificationinterface.cpp). Note in particular that there is
no need to conditionally include zmq.h only if ZMQ is enabled, because
the place in the core code where the ZMQ library itself is included
(init.cpp) is conditional already on that.
This commit removes zmqconfig.h and replaces it by a much simpler
zmqutil.h library for zmqError. The definition of the function is
moved to the matching (newly created) zmqutil.cpp.

Pull request description:
This PR continues and completes the work begun in #17700 working on issue #16000 to create a client-side version of RPC `generate`.
Basically, `bitcoin-cli -generate` wraps calling `generatenewaddress` followed by `generatetoaddress [nblocks] [maxtries]` and prints the following:
```
$ bitcoin-cli -generate
{
"address": "bcrt1qn4aszr2y2xvpa70y675a76wsu70wlkwvdyyln6"
"blocks": [
"01d2ebcddf663da90b28da7f6805115e2ba7818f16fe747258836646a43a0bb5",
]
}
$ bitcoin-cli -rpcwallet=wallet-name -generate 3 100
{
"address": "bcrt1q4cunfw0gnsj7g7e6mk0v0uuvvau9mwr09dj45l",
"blocks": [

]
}
```
Help doc:
```
$ bitcoin-cli -h | grep -A5 "\-generate"
-generate
Generate blocks immediately, equivalent to RPC generatenewaddress
followed by RPC generatetoaddress. Optional positional arguments
are number of blocks to generate (default: 1) and maximum
iterations to try (default: 1000000), equivalent to RPC
generatetoaddress nblocks and maxtries arguments. Example:
bitcoin-cli -generate 4 1000
```
Quite a bit of test coverage turned out to be needed to cover the change and the different cases (arguments, multiwallet mode) and error-handling.
This PR also improves some things that working on these changes brought to light.

Pull request description:
This PR removes the `g_rpc_node` global, to get same benefits we see removing other globals and make RPC code more testable, modular, and reusable.
This uses a hybrid of the approaches suggested in #17548. Instead of using `std::any`, which isn't available in c++11, or `void*`, which isn't type safe, it uses a small new `util::Ref` helper class, which acts like a simplified `std::any` that only holds references, not values.
Motivation for writing this was to provide an simpler alternative to #18647 by Harris Brakmić (brakmic) which avoids some shortcomings of that PR (https://github.com/bitcoin/bitcoin/pull/18647#issuecomment-617878826)

Pull request description:
This PR is part of the [process separation project](https://github.com/bitcoin/bitcoin/projects/10).
---
This PR consists of build changes only. It adds an `--enable-multiprocess` autoconf option (off by default and marked experimental), that builds new `bitcoin-node` and `bitcoin-gui` binaries. These currently function the same as existing `bitcoind` and `bitcoin-qt` binaries, but are extended in #10102 with IPC features to execute node, wallet, and gui functions in separate processes.
In addition to adding the `--enable-multiprocess` config flag, it also adds a depends package and autoconf rules to build with the [libmultiprocess](https://github.com/chaincodelabs/libmultiprocess) library, and it adds new travis configuration to exercise the build code and run functional tests with the new binaries.
The changes in this PR were originally part of #10102 but were moved into #16367 to be able to develop and review the multiprocess build changes independently of the code changes. #16367 was briefly merged and then reverted in #18588. Only change since #16367 has been dropping the `native_boost.mk` depends package which was pointed out to be no longer necessary in https://github.com/bitcoin/bitcoin/pull/16367#issuecomment-596484337 and https://github.com/bitcoin/bitcoin/pull/18588#pullrequestreview-391765649

autoconf and automake changes to support multiprocess gui/node/wallet execution.
This adds a new --enable-multiprocess flag, and build configuration code to
detect libraries needed for multiprocess support. The --enable-multiprocess
flag builds new bitcoin-node and bitcoin-gui executables, which are updated in
https://github.com/bitcoin/bitcoin/pull/10102 to communicate across processes.
But for now they are functionally equivalent to existing bitcoind and
bitcoin-qt executables.
As is, this sanity check doesn't seem to be testing fdelt_chk, because
passing a value of "0" to FD_SET wont cause the compiler to insert any
calls to fdelt_chk().
The documentation is a little misleading. If we actually triggered fdelt_chk
at runtime, bitcoind would abort. I think this check would be better replaced
(if possible) by additional checks in security-check.py.
The compiler may insert a call to fdelt_warn() (aliased with fdelt_chk
in glibc) at compile time if it can determine that an invalid value is
being passed to FD_SET.
These checks are essentially; value < 0 or value >= FD_SETSIZE along
with a check for wether the value is a compile time constant.
If the compiler can determine an invalid value is being passed, a call
to fdelt_warn will be inserted. Passing 0 should never cause a call to
be inserted.
You can check this after compiling:
```bash
objdump -dC bitcoind | grep sanity_fdelt
...

To test, you could modify this test to pass -1 to FD_SET, and check
