9b0a13a2891641a3d12e525cee8ddddb1aa1bc73 tidy: Add include-what-you-use (fanquake) 74cd038e300bfbe2473295fc3b0c3a4f3e853a07 refactor: fix includes in src/init (fanquake) c79ad935f0412bac3e19a6b925efdb390eb00bd9 refactor: fix includes in src/compat (fanquake) Pull request description: We recently added a [`clang-tidy` job](https://github.com/bitcoin/bitcoin/blob/master/ci/test/00_setup_env_native_tidy.sh) to the CI, which generates a compilation database. We can leverage that now existing database to begin running [include-what-you-use](https://include-what-you-use.org/) over the codebase. This PR demonstrates using a mapping_file to indicate fixups / includes that may differ from IWYU suggestions. In this case, I've added some fixups for glibc includes that I've [upstreamed changes for](https://github.com/include-what-you-use/include-what-you-use/pull/1026): ```bash # Fixups / upstreamed changes [ { include: [ "<bits/termios-c_lflag.h>", private, "<termios.h>", public ] }, { include: [ "<bits/termios-struct.h>", private, "<termios.h>", public ] }, { include: [ "<bits/termios-tcflow.h>", private, "<termios.h>", public ] }, ] ``` The include "fixing" commits of this PR: * Adds missing includes. * Swaps C headers for their C++ counterparts. * Removes the pointless / unmaintainable `//for abc, xyz` comments. When using IWYU, if anyone wants to see / generate those comments, to see why something is included, it is trivial to do so (IWYU outputs them by default). i.e: ```cpp // The full include-list for compat/stdin.cpp: #include <compat/stdin.h> #include <poll.h> // for poll, pollfd, POLLIN #include <termios.h> // for tcgetattr, tcsetattr #include <unistd.h> // for isatty, STDIN_FILENO ``` TODO: - [ ] Qt mapping_file. There is one in the IWYU repo, but it's for Qt 5.11. Needs testing. - [ ] Boost mapping_file. There is one in the IWYU repo, but it's for Boost 1.75. Needs testing. I'm not suggesting we turn this on the for entire codebase, or immediately go-nuts refactoring all includes. However I think our dependency includes are now slim enough, and our CI infrastructure in place such that we can start doing this in some capacity, and just automate away include fixups / refactorings etc. ACKs for top commit: MarcoFalke: review ACK 9b0a13a2891641a3d12e525cee8ddddb1aa1bc73 jonatack: ACK 9b0a13a2891641a3d12e525cee8ddddb1aa1bc73 reviewed changes and run CI output in https://cirrus-ci.com/task/4750910332076032 Tree-SHA512: 00beab5a5f2a6fc179abf08321a15391ecccaa91ab56f3c50c511e7b29a0d7c95d8bb43eac2c31489711086f6f77319d43d803cf8ea458e7cd234a780d9ae69e

What is Bitcoin?
Bitcoin is an experimental digital currency that enables instant payments to anyone, anywhere in the world. Bitcoin uses peer-to-peer technology to operate with no central authority: managing transactions and issuing money are carried out collectively by the network. Bitcoin Core is the name of open source software which enables the use of this currency.

License
Bitcoin Core is released under the terms of the MIT license. See COPYING for more information or see https://opensource.org/licenses/MIT.
Development Process
The master branch is regularly built (see doc/build-*.md for instructions) and tested, but it is not guaranteed to be
completely stable. Tags are created
regularly from release branches to indicate new official, stable release versions of Bitcoin Core.
The https://github.com/bitcoin-core/gui repository is used exclusively for the development of the GUI. Its master branch is identical in all monotree repositories. Release branches and tags do not exist, so please do not fork that repository unless it is for development reasons.
The contribution workflow is described in CONTRIBUTING.md and useful hints for developers can be found in doc/developer-notes.md.
Testing
Testing and code review is the bottleneck for development; we get more pull requests than we can review and test on short notice. Please be patient and help out by testing other people's pull requests, and remember this is a security-critical project where any mistake might cost people lots of money.
Automated Testing
Developers are strongly encouraged to write unit tests for new code, and to
submit new unit tests for old code. Unit tests can be compiled and run
(assuming they weren't disabled in configure) with: make check. Further details on running
and extending unit tests can be found in /src/test/README.md.
There are also regression and integration tests, written
in Python.
These tests can be run (if the test dependencies are installed) with: test/functional/test_runner.py
The CI (Continuous Integration) systems make sure that every pull request is built for Windows, Linux, and macOS, and that unit/sanity tests are run automatically.
Manual Quality Assurance (QA) Testing
Changes should be tested by somebody other than the developer who wrote the code. This is especially important for large or high-risk changes. It is useful to add a test plan to the pull request description if testing the changes is not straightforward.
Translations
Changes to translations as well as new translations can be submitted to Bitcoin Core's Transifex page.
Translations are periodically pulled from Transifex and merged into the git repository. See the translation process for details on how this works.
Important: We do not accept translation changes as GitHub pull requests because the next pull from Transifex would automatically overwrite them again.
