b062da0090 contrib: add check for wget command in install_db4.sh (Florian Baumgartl)
Pull request description:
This PR is motivated by 7bb8eb0bc3 commit (see also https://github.com/bitcoin/bitcoin/pull/23579) and ensures that `install_db4.sh` will check for `curl` and `wget` utilities. Currently, the conditional statement in the `http_get()` function assumes that `wget` is always available but we actually do not know it since there is no check or validation for the `wget` command. So let's make sure that we check for both commands and print an error message if they are missing.

2f356a0ca8 scripted-diff: Drop Darwin version for better maintainability (Hennadii Stepanov)
Pull request description:
After this PR, any macOS tools version bumping in the future will touch fewer files in the repo.
Pointing a Darwin version for the `--host` system does not matter for the following reasons:
- in terms of the resulted binaries, we should only care about the minimum supported macOS version which is a separated parameter in our build system.
- in terms of the build system itself, the usage of the `$(host)` variable is self-consistent enough. Btw `$(host_os)` value already has the version dropped:
```
$ make -C depends --no-print-directory print-host_os HOST=x86_64-apple-darwin19
host_os=darwin

a3f61676e8 test: Make more shell scripts verifiable by the `shellcheck` tool (Hennadii Stepanov)
Pull request description:
Some shell scripts from `contrib/guix` and `contrib/shell` are not verifiable by the `shellcheck` tool for the following reasons:
- they have no extension (see 4eccf063b2 from bitcoin/bitcoin#21375)

From what I can see the only platform this drops support for is CentOS
7. CentOS 7 reached the end of it's "full update" support at the end of
2020. It does receive maintenance updates until 2024, however I don't
think supporting glibc 2.17 until 2024 is realistic. Note that anyone
wanting to self-compile and target a glibc 2.17 runtime could build with
--disable-threadlocal.
glibc 2.18 was released in August 2013.

365f35481d script: Add commits signed with sipas expired key to allow-revsig-commits (nthumann)
Pull request description:
Fixes https://github.com/bitcoin/bitcoin/issues/22737.
While investigating the issue above, I noticed that there are 141 commits that are signed with sipas expired key.
To allow `./contrib/verify-commits/verify-commits.py` to succeed, this PR adds them to `allow-revsig-commits`.
Feel free to confirm that they're indeed signed with an expired key using e.g. `git show --show-signature d8cd7b137fb075616f31d2b43b85fa2e27ea7477` :)

A few more build issues came up (and have been fixed) since, and after discussing with sipa it was decided I would open a PR to shepherd any final changes through.
> This adds a `src/minisketch` subtree, taken from the master branch of https://github.com/sipa/minisketch, to prepare for Erlay implementation (see #21515). It gets configured for just supporting 32-bit fields (the only ones we're interested in in the context of Erlay), and some code on top is added:
> * A very basic unit test (just to make sure compilation & running works; actual correctness checking is done through minisketch's own tests).
> * A wrapper in `minisketchwrapper.{cpp,h}` that runs a benchmark to determine which field implementation to use.
Only changes since my last update to the branch in the previous PR have been rebasing on master and fixing an issue with a header in an introduced file.

0f95247246 Integrate univalue into our buildsystem (Cory Fields)
9b49ed656f Squashed 'src/univalue/' changes from 98fadc0909..a44caf65fe (fanquake)
Pull request description:
This PR more tightly integrates building Univalue into our build system. This follows the same approach we use for [LevelDB](https://github.com/bitcoin-core/leveldb/), ([`Makefile.leveldb.include`](https://github.com/bitcoin/bitcoin/blob/master/src/Makefile.leveldb.include)), and [CRC32C](https://github.com/bitcoin-core/crc32c) ([`Makefile.crc32c.include`](https://github.com/bitcoin/bitcoin/blob/master/src/Makefile.crc32c.include)), and will be the same approach we use for [minisketch](https://github.com/sipa/minisketch); see #23114.
This approach yields a number of benefits, including:
* Faster configuration due to one less subconfigure being run during `./configure` i.e 22s with this PR vs 26s
* Faster autoconf i.e 13s with this PR vs 17s
* Improved caching
* No more issues with compiler flags i.e https://github.com/bitcoin/bitcoin/pull/12467
* More direct control means we can build exactly the objects we want
There might be one argument against making this change, which is that builders should have the option to use "proper shared/system libraries". However, I think that falls down for a few reasons. The first being that we already don't support building with a number of system libraries (secp256k1, leveldb, crc32c); some for good reason. Univalue is really the odd one out at the moment.
Note that the only fork of Core I'm aware of, that actively patches in support for using system libs, also explicitly marks them as ["DANGEROUS"](a886811721/configure.ac (L1430)) and ["NOT SUPPORTED"](a886811721/configure.ac (L1312)). So it would seem they exist more to satisfy a distro requirement, as opposed to something that anyone should, or would actually use in practice.
PRs like #22412 highlight the "issue" with us operating with our own Univalue fork, where we actively fix bugs, and make improvements, when upstream (https://github.com/jgarzik/univalue) may not be taking those improvements, and by all accounts, is not currently actively maintained. Bitcoin Core should not be hamstrung into not being able to fix bugs in a library, and/or have to litter our source with "workarounds", i.e #22412, for bugs we've already fixed, based on the fact that an upstream project is not actively being maintained. Allowing builders to use system libs is really only exacerbating this problem, with little benefit to our project. Bitcoin Core is not quite like your average piece of distro packaged software.
There is the potential for us to give the same treatment to libsecp256k1, however it seems doing that is currently less straightforward.

The tracepoint `validation:block_connected` was introduced in #22006.
The first argument was the hash of the connected block as a pointer
to a C-like String. The last argument passed the hash of the
connected block as a pointer to 32 bytes. The hash was only passed as
string to allow `bpftrace` scripts to print the hash. It was
(incorrectly) assumed that `bpftrace` cannot hex-format and print the
block hash given only the hash as bytes.
The block hash can be printed in `bpftrace` by calling
`printf("%02x")` for each byte of the hash in an `unroll () {...}`.
By starting from the last byte of the hash, it can be printed in
big-endian (the block-explorer format).
```C
$p = $hash + 31;
unroll(32) {
$b = *(uint8*)$p;
printf("%02x", $b);
$p -= 1;
}
```

This is a breaking change to the block_connected tracepoint API, however
this tracepoint has not yet been included in a release.
It is important that binaries request a standard interpreter location
where most distros would place the linker-loader. Otherwise, the user
would be met with a very confusing message:
bash: <path>/<to>/bitcoind: No such file or directory
When really it's the interpreter that's not found.
I used Guix's values for the powerpc64(le) dynamic linkers, and the
/lib-prefix seems to be a Guix-ism rather than standard. The standard
path for the linker-loaders start with /lib64.
I've taken the new loader values from SYSDEP_KNOWN_INTERPRETER_NAMES in
glibc's sysdeps/unix/sysv/linux/powerpc/ldconfig.h file.
For future reference, loader path values can also be found on glibc's
website: https://sourceware.org/glibc/wiki/ABIList?action=recall&rev=16
These test-*-check scripts should compile "test" binaries in a way that
is as close to what autotools would do, since the goal is to make sure
that if we run the *-check script, they can correctly detect flaws in
binaries which are compiled by our autotools-based system.
Therefore, we should emulate what happens when the binary is linked in
autotools, meaning that for C binaries, we need to supply the CFLAGS,
CPPFLAGS, and LDFLAGS flags in that order.
Note to future developers: perhaps it'd be nice to have these
test-*-check scripts be part of configure.ac to avoid having to manually
replicate autoconf-like behaviour every time we find a discrepancy. Of
course, that would also mean you'd have to write more m4...
This addresses issues like the one in #12467, where some of our compiler flags
end up being dropped during the subconfigure of Univalue. Specifically, we're
still using the compiler-default c++ version rather than forcing c++17.
We can drop the need subconfigure completely in favor of a tighter build
integration, where the sources are listed separately from the build recipes,
so that they may be included directly by upstream projects. This is
similar to the way leveldb build integration works in Core.
Core benefits of this approach include:
- Better caching (for ex. ccache and autoconf)
- No need for a slow subconfigure
- Faster autoconf
- No more missing compile flags
- Compile only the objects needed
There are no benefits to Univalue itself that I can think of. These changes
should be a no-op there, and to downstreams as well until they take advantage
of the new sources.mk.
This also removes the option to use an external univalue to avoid similar ABI
issues with mystery binaries.

a43b8e9555 build: set OSX_MIN_VERSION to 10.15 (fanquake)
Pull request description:
Taken out of #20744, as splitting up some of the build changes was mentioned [here](https://github.com/bitcoin/bitcoin/pull/22937#discussion_r707303172).
This is required to use `std::filesystem` on macOS, as support for it only landed in the libc++.dylib shipped with 10.15. So if we want to move to using `std::filesystem` for `23.0`, this bump is required.
See also: https://developer.apple.com/documentation/xcode-release-notes/xcode-11-release-notes
> Clang now supports the C++17 \<filesystem\> library for iOS 13, macOS 10.15, watchOS 6, and tvOS 13.
macOS 10.15 was released in October 2019. macOS OS's seem to have a life of about 3 years, so it's possible that 10.14 will become officially unsupported by the end of 2021 and prior to the release of 23.0.

96cc6bb04f guix/prelude: Override VERSION with FORCE_VERSION (Carl Dong)
Pull request description:
```
Previously, if the builder exported $VERSION in their environment (as
past Gitian-building docs told them to), but their HEAD does not
actually point to v$VERSION, their build outputs will differ from those
of other builders.
This is because the contrib/guix/guix-* scripts only ever act on the
current git worktree, and does not try to check out $VERSION if $VERSION
is set in the environment.
Setting $VERSION only makes the scripts pretend like the current
worktree is $VERSION.
This problem was seen in jonatack's attestation for all.SHA256SUMS,
where only his bitcoin-22.0rc3-osx-signed.dmg differed from everyone
else's.
Here is my deduced sequence of events:
1. Aug 27th: He guix-builds 22.0rc3 and uploads his attestations up to
guix.sigs
2. Aug 30th, sometime after POSIX time 1630310848: he pulls the latest
changes from master in the same worktree where he guix-built 22.0rc3
and ends up at 7be143a960
3. Aug 30th, sometime before POSIX time 1630315907: With his worktree
still on 7be143a960, he guix-codesigns. Normally, this would result
in outputs going in guix-build-7be143a960e2, but he had
VERSION=22.0rc3 in his environment, so the guix-* scripts pretended
like he was building 22.0rc3, and used 22.0rc3's guix-build directory
to locate un-codesigned outputs and dump codesigned ones.
However, our SOURCE_DATE_EPOCH defaults to the POSIX time of HEAD
(7be143a960), which made all timestamps in the resulting codesigned
DMG 1630310848, 7be143a960e2's POSIX timestamp. This differs from the
POSIX timestamp of 22.0rc3, which is 1630348517. Note that the
windows codesigning procedure does not consider SOURCE_DATE_EPOCH.
We resolve this by only allowing VERSION overrides via the FORCE_VERSION
environment variable.

Pull request description:
This PR is based on #22565 ("[script] signet's getcoins.py improvements"), which should be reviewed first.
The signet faucet script `contrib/signet/getcoins.py` currently issues bitcoin-cli RPC calls without catching errors -- the only case tackled is if there is no `bitcoin-cli` file found. Instead of crashing with a stack-trace on a failed RPC call, the changes in this PR aim to produce a more user-friendly output (see also https://github.com/bitcoin/bitcoin/pull/22565#discussion_r683754875). Additionally, in case of any error, a non-zero status is now returned (instead of 0, indicating success), which could be useful for other scripts taking use of signet faucet script.
The most straight-forward way to test this is invoking the script without a `bitcoind` running on signet:

This PR adds a sanity check for custom signet by comparing the current network's first block hash (the block after the genesis block) with global signet's respective block hash (since all signet networks share the same genesis block) and if a custom network is detected, the user is prompted to either work on the global signet or setup their own faucet.
The PR was checked to be working successfully, giving the output as below:
```
[nikhilb@nikhil-PC bitcoin]$ git checkout update_signet_getcoins

The global faucet cannot be used with a custom Signet network. Please use the global signet or setup your custom faucet for the same.

132cae44f2 doc: Mention the flat directory structure for uploads (Andrew Chow)
fb17c99e35 guix: Don't include directory name in SHA256SUMS (Andrew Chow)
Pull request description:
The SHA256SUMS file can be used in a sha256sum -c command to verify downloaded binaries. However users are likely to download just a single file and not place this file in the correct directory relative to the SHA256SUMS file for the simple verification command to work. By not including the directory name in the SHA256SUMS file, it will be easier for users to verify downloaded binaries.

5449d44e37 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.
