a5ac43d98ddoc: Add release notes describing bitcoin wrapper executable (Ryan Ofsky)258bda80c0doc: Mention bitcoin wrapper executable in documentation (Ryan Ofsky)d2739d75c9build: add bitcoin.exe to windows installer (Sjors Provoost)ba649c0006ci: Run multiprocess tests through wrapper executable (Ryan Ofsky)29bdd743bbtest: Support BITCOIN_CMD environment variable (Ryan Ofsky)9c8c68891bmultiprocess: Add bitcoin wrapper executable (Ryan Ofsky)5076d20fdbutil: Add cross-platform ExecVp and GetExePath functions (Ryan Ofsky) Pull request description: Intended to make bitcoin command line features more discoverable and allow installing new multiprocess binaries in libexec/ instead of bin/ so they don't cause confusion. Idea and implementation of this were discussed in https://github.com/bitcoin/bitcoin/issues/30983. --- Initial implementation of this feature is deliberately minimal so the UX can evolve in response to feedback and there are not too many details to debate and discuss in a single PR. But many improvements are possible or planned: - Adding manpage and bash completions. - Showing nicer error messages that detect if an executable isn't installed and suggest how to fix [(comment)](https://github.com/bitcoin/bitcoin/pull/31375#discussion_r2073194474) - Showing wrapper command lines in subcommand in help output [(comment)](https://github.com/bitcoin/bitcoin/pull/31375#discussion_r2077800405). This could be done conditionally as suggested in the comment or be unconditional. - Showing wrapper command lines in subcommand error output. There is a bitcoin-cli error pointed out in [(comment)](https://github.com/bitcoin/bitcoin/pull/31375#discussion_r2091152243) that is needlessly confusing. - Integrating help so `bitcoin help subcommand` invokes `bitcoin subcommand -h`. `bitcoin -h subcommand` should also be supported and be equivalent [(comment)](https://github.com/bitcoin/bitcoin/pull/31375#discussion_r2093116725) - Adding support for `bitcoin-util` subcommands. Ideal interface would probably be more like `bitcoin grind` not `bitcoin util grind` but this has been punted for now. Supporting subcommands directly would require some ArgsManager modifications - Adding a dedicated python functional test for the wrapper. Right now there is some CI coverage by setting the `BITCOIN_CMD` variable, but this doesn't cover things like the help output and version output, and support for different directory layouts. - Better `--multiprocess` (`-m`) / `--monolithic` (`-M`) default selection. Right now, default is monolithic but it probably makes sense to chose more intelligently depending on whether -ipc options are enabled and what binaries are available. - Maybe parsing `bitcoin.conf` and supporting options to control wrapper behavior like custom locations or preferences or aliases. - Better command command line usability. Allow combining short options like (`-ah`). Allow fuzzy matching of subcommands or suggestions if you misspell. (suggested by stickies in review club) - Not directly related to this PR but `bitcoin-cli named` implementation used by the wrapper should do a better job disambiguating named arguments from base64 arguments ending in = as pointed out in [(comment)](https://github.com/bitcoin/bitcoin/pull/31375#discussion_r2091886628) --- This PR is part of the [process separation project](https://github.com/bitcoin/bitcoin/issues/28722).

Bitcoin Core integration/staging tree
For an immediately usable, binary version of the Bitcoin Core software, see https://bitcoincore.org/en/download/.
What is Bitcoin Core?
Bitcoin Core connects to the Bitcoin peer-to-peer network to download and fully validate blocks and transactions. It also includes a wallet and graphical user interface, which can be optionally built.
Further information about Bitcoin Core is available in the doc folder.
License
Bitcoin Core is released under the terms of the MIT license. See COPYING for more information or see https://opensource.org/license/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 during the generation of the build system) with: ctest. 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: build/test/functional/test_runner.py
(assuming build is your build directory).
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.
