88d4d5ff2f rpc: add help for enumeratesigners and walletdisplayaddress (Sjors Provoost)
b0db187e5b ci: use --enable-external-signer instead of --with-boost-process (Sjors Provoost)
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`.

An earlier version of #16546 used both --with-boost-process and --enable-external-signer, which was simplified to only use the latter. However I forgot to update CI, so the external signer tests were not run.
The depends dir can not be overwritten by a FILE_ENV file. Also, a FILE_ENV file
might depend on the DEPENDS_DIR value. Thus, set it before reading FILE_ENV.
This commit does not change behavior, but is required for later commits.

This package is currently installed as a side-effect of installing our
other libboost-*-dev packages. However as those continue to dissapear,
it makes sense to install boost dev explicitly.

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.

2ecaf21433 gitian: remove execstack workaround for ricv64 & powerpc64le (fanquake)
5baff2b318 build: use focal in gitian descriptors (fanquake)
Pull request description:
This PR changes the gitian descriptors to use Ubuntu Focal (20.04), over Bionic (18.04), moving from GCC 7.5 to GCC 8.4 for native Linux builds, mingw-w64 GCC 7.3 to mingw-w64 GCC 9.3 for Windows builds, while continuing to use GCC 8.4 for all cross builds and Clang 8.0.0 for macOS builds.
It also drops the `-Wl,-z,noexecstack` workaround we've been using for the riscv64 and powerpc64le hosts, as it's no-longer needed. One new package is installed in the osx build, `libtinfo5`, as libtinfo5.so is required by our downloaded Clang 8.
A bump to Focal will at least be required if we want to update to a newer Qt (5.15, #19716) for 22.0, as we need a newer version of [`g++-mingw-w64`](https://packages.ubuntu.com/focal/g++-mingw-w64-x86-64) and the [`mingw-w64`](https://mingw-w64.org/doku.php) headers. This can still be done while continuing to use GCC 8.4 for Linux builds (see below), however the newer `g++-mingw-w64` will be based off of GCC 9.3.
**Some considerations**
GCC 9 is affected by #20005 "memcmp with constants that contain zero bytes are broken in GCC", and the newer `g++-mingw-w64` will be based off of GCC 9.3.
The `--no-*` variants of the Windows linker flags (i.e `--no-dynamicbase`) we use to [test our `security-check.py` script](16b784d953/contrib/devtools/test-security-check.py (L53)) are not patched into the mingw binutils in Focal (they have been re-added in Groovy (20.10)). This isn't currently an issue, however, we might add a call to `test-security-check` for Guix (#20980), and if we wanted to do the same for gitian, it would not work. Note how it's quite "easy" for us to apply the `--no-*` variant patch to our Guix build; it would be quite a bit harder to do in Gitian.

This fixes issue #19388. The changes are as follows:
- Add a new flag to configure, --enable-fuzz-binary, which allows building test/fuzz/fuzz regardless of whether we are building to do actual fuzzing
- Set -DPROVIDE_MAIN_FUNCTION whenever --enable-fuzz is no
- Add the following libraries to FUZZ_SUITE_LD_COMMON:
- LIBBITCOIN_WALLET
- SQLLITE_LIBS
- BDB_LIBS
- if necessary, some or all of:
- NATPMP_LIBS
- MINIUPNPC_LIBS
- LIBBITCOIN_ZMQ / ZMQ_LIBS
Compilers used change as follows:
Linux native GCC 7.5 -> GCC 8.4
Linux cross GCC 8.4 -> GCC 8.4
Windows mingw-w64 7.3 -> mingw-w64 9.3
macOS Clang 8.0.0 -> Clang 8.0.0
The macOS and Win cross builds in the CI are updated to use Focal, and
per the op, running the security tests is disabled in the Windows
build.
xorriso and its mkisofs/genisoimage emulation alter-ego xorrisofs are
more maintained, and has the right toggles for us to achieve output
determinism without using blunt tools like faketime.
In this commit, we use xorrisofs from the build environment rather than
building it ourselves using depends. This is not necessary and can be
changed in the future.
From https://wiki.debian.org/genisoimage?action=recall&rev=11 :

Pull request description:
Add MemorySanitizer (MSan) in Travis to detect use of uninitialized memory.
First UBSan, then ASan followed by TSan... and now: yes, the wait is over -- **MSan is finally here!** :)
Some historical context:
* 2017: Continuous compilation with Clang Thread Safety analysis enabled (#10866, #10923)
* 2018: Continuous testing with trapping on signed integer overflows (`-ftrapv`) (#12686)
* 2018: Continuous testing of use of locale dependent functions (#13041)
* 2018: Continuous testing of format strings (#13705)

* 2018: Continuous testing under UndefinedBehaviorSanitizer – UBSan (#14252, #14673, #17006)
* 2018: Continuous testing under AddressSanitizer – ASan (#14794, #17205, #17674)
* 2018: Continuous testing under ThreadSanitizer – TSan (#14829)
* 2019: Continuous testing in an unsigned char environment (`-funsigned-char`) (#15134)
* 2019: Continuous compile-time testing of assumptions we're making (#15391)
* 2019: Continuous testing of fuzz test cases under Valgrind (#17633, #18159, #18166)
* 2020: Finally... MemorySanitizer – MSAN! :)
What is the next step? What tools should we add to CI to keep bugs from entering `master`? :)

a92e48b02d test: move TEST_RUNNER_EXTRA into native tsan setup (fanquake)
Pull request description:
`feature_block.py` is being run in the tsan job, i.e [here](https://travis-ci.org/github/bitcoin/bitcoin/jobs/703122309), even though it should be excluded. My hasty assumption is that this will fix it. In any case, all other instances of `TEST_RUNNER_EXTRA` seem to have moved out of `.travis.yml` and into the different CI configurations.

b3394ab235 contrib: macdeploy: Correctly generate macOS SDK (Carl Dong)
Pull request description:
This PR achieves 3 main things:
1. It simplifies the macOS SDK generation by putting the logic inside a (semi-)portable python3 script `gen-sdk`
2. It transitions us to using `libc++` headers extracted from the `Xcode.app`, which is more correct as those headers better match the `.tbd` library stubs we use from the `MacOSX.sdk` (located under the same `Xcode.app`). Previously, we used `libc++` headers copied from our downloaded, pinned clang (see `native_cctools.mk`).
3. It bumps the macOS toolchain in a way that fulfills all of the following constraints:
1. The new SDK should support compiling with C++17 (our current one doesn't)
2. The new toolchain should not change our minimum supported macOS version (`-mmacosx-version-min`)
3. The new toolchain should expect to use a version of `cctools` that is supported by https://github.com/tpoechtrager/cctools-port
For the constraints in (3), you can reference [this chart](https://en.wikipedia.org/wiki/Xcode#Xcode_7.0_-_11.x_(since_Free_On-Device_Development)) to see that the newest toolchain we can use with our `cctools-port` is `11.3.1`, and the rest of the constraints were tested with local builds.
#### But [the other Wikipedia chart](https://en.wikipedia.org/wiki/Xcode#Xcode_11.x_(since_SwiftUI_framework)) says that the "min macOS to run" for Xcode 11.3.1 is 10.14.4, doesn't that violate constraint (ii)?
This confused me at first too, but the "min macOS to run" is for the Xcode.app App itself. The SDK still supports 10.12, as evident in a few plist files and as proven through local builds.
#### Why bundle all of this together in a single PR?
We need (1) and (2) together, because if we don't, manually adding the `libc++` headers and writing that out in a `README.md` is going to result in a lot of user error, so it's great to have these together to be more correct and also make it easier on the user at the same time.
We need (3) together with everything else because bumping (or in the case of (1), renaming) the SDK requires some human coordination and may break some builds. And since it's not that complicated a change, it makes sense to do it together with the rest.

5d1377b52b build: multiprocess autotools changes (Russell Yanofsky)
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

45615de26c ci: Fix default retry script usage (Hennadii Stepanov)
Pull request description:
On master (5352d14b37) `CI_RETRY_EXE=${CI_RETRY_EXE:retry}` works as a [Substring Expansion](https://www.gnu.org/software/bash/manual/html_node/Shell-Parameter-Expansion.html), and that is wrong.
If `CI_RETRY_EXE` variable was unset initially, its new value becomes an empty string, but not "retry" as one could expect. Consequently, the `${CI_RETRY_EXE} ...` command does _not_ use `ci/retry/retry` script.
This PR makes for `CI_RETRY_EXE` variable a usual parameter expansion, i.e., `${parameter:-word}`.

Pull request description:
When writing tests, often includes need to be added or removed. Currently the list of includes is not sorted, so developers that write tests and have `clang-format` installed will either have an unrelated change (sorting) included in their commit or they will have to manually undo the sort.
This pull preempts both issues by just sorting all includes in one commit.
Please be aware that this is **NOT** a change to policy to enforce clang-format or any other developer guideline or process. Developers are free to use whatever tool they want, see also #18651.
Edit: Also includes a commit to bump the copyright headers, so that the touched files don't need to be touched again for that.

Pull request description:
Now that the ci system no longer propagates files from the docker container back to the host, the wrap-qemu script is broken.
To fix it, every statement in the script needs to be executed in the docker (with `DOCKER_EXEC`). Instead of juggling with triple escape sequences like `\\\"`, just move the script to a separate file and call it with `DOCKER_EXEC`.
Also, fix a bunch of other bugs that prevent running the ci system in qemu

ef63f5fc11 ci: Combine 32-bit build with CentOS 7 build (Sebastian Falbesoner)
Pull request description:
Combines the CentOS build with the 32-bit (i686) build to avoid Travis bottlenecks, as suggested in #17757 by MarcoFalke. This keeps most of the properties of the 32-bit build (dash as config shell, building QT5 GUI) and just builds it with depends inside the CentOS docker container.
Making the depends in `05_before_script.sh` with unset config shell (`CONFIG_SHELL=`)
6196e93001/ci/test/05_before_script.sh (L28)
caused problems for building the library libevent (resulting in a Makefile with no shell set (`SHELL=`)), that's why I set it explicitely to `/bin/bash` if we have a CentOS Docker container.
A Travis output of this 32-bit CentOS build can be seen here: https://travis-ci.org/theStack/bitcoin/jobs/634472394 (has been restarted once due to too long build time and appearance of the `CACHE_ERR_MSG`).
For anyone wanting to verify the outputs, I found these instructions useful to reproduce a Travis build locally: https://github.com/erdc/proteus/wiki/Replicating-the-TravisCI-Environment-on-your-Local-Machine (steps 1-3). In this case it's a bit tricky since you run Docker inside Docker -- within the Travis Docker container, the CentOS Docker container is created. To make this possible, the Docker socket has to be exposed to the Travis container via bind-mounting (`docker run -v /var/run/docker.sock:/var/run/docker.sock ...`), as suggested in https://stackoverflow.com/a/33003273.

~Please note that this PR is based on the bugfix #17634.~
Also trusty build has been removed for the following reasons:
- https://github.com/bitcoin/bitcoin/issues/17628#issuecomment-559448201:
> Maybe it'd make sense to replace Ubuntu Trusty with Centos 7 as the "check ancient backward compatibililty" Travis run. It's supported until 2024, apparently.
- https://github.com/bitcoin/bitcoin/pull/17635#discussion_r354811792:
> Our travis is currently running at its limit and this doesn't seem like it is adding a lot new coverage compared to the other builds.

* Add some documentation to folders and remove the `BASE_BUILD_DIR` alias for the root directory
* Fixes#17178 by removing `cd`

Pull request description:
Running the ci completely in a docker, without leaving any traces on the host system is not possible right now because the ccache and depends dir needs to be propagated back and picked up by the host for caching.
Fixes#17372

30fb598737 Fix segfault in allocator_tests/arena_tests (Jeffrey Czyz)
15c84f53f4 Define ARENA_DEBUG in Travis test runs (Jeffrey Czyz)
ad71548822 Fix compilation errors in support/lockedpool.cpp (Jeffrey Czyz)
Pull request description:
Changes in #12048 cause a compilation error in Arena::walk() when
ARENA_DEBUG is defined. Specifically, Arena's chunks_free map was
changed to have a different value type.
Additionally, missing includes cause other compilation errors when
ARENA_DEBUG is defined.
Reproduced with:
make CPPFLAGS=-DARENA_DEBUG

The definition and uses of Arena::walk() are compiled only if
ARENA_DEBUG is defined. Configure Travis to define ARENA_DEBUG so
compilation errors do not go unnoticed.
facc0da63a travis: Run unit and functional tests on native arm (MarcoFalke)
fafa064d2a ci: Remove ccache requirement on the host (MarcoFalke)
Pull request description:
This keeps the cross-compilation to make it easy to run the ci on non-arm hardware. To run this locally in qemu-user as it used to be, just `export QEMU_USER_CMD="qemu-arm -L /usr/arm-linux-gnueabihf/"`.
