Bumps boost from `1.70.0` to `1.71.0`, because `1.71.0`: 1. Removes the need to patch out the unused variable.f8462a6d27/depends/packages/boost.mk (L36)Upstream boost patched it out ind20b64cf37, which was first included in the `1.71.0` release 2. Comes packaged with a version of `b2` which allows us to override its `CXX` and `CXXFLAGS`. Previously, choosing a toolset while building `b2` such as `clang` or `gcc` would force `b2`'s build system to invoke the compiler as a bare, hardcoded `clang` or `gcc`. However, our `depends` build system often want to customize this behaviour, adding extra flags or invoking the compiler by an alternate name. So this is useful. 1. Commit where `CXX` was introduced:374f96516a2. Commit where `CXXFLAGS` was introduced:5d49abc1f22. The boost package is now split into `native_b2` and `boost`, better representing what actually happens. - In our `depends` build system, we have a distinction between `native` packages and non-`native` packages. The output of `native` packages are meant to be used on the machine that's performing the build, and the output of non-`native` packages are meant to be used on/for the machine that will ultimately be running bitcoin. Previously, `boost` existed in `depends` as a non-`native` package, but that's partly inaccurate because the `./bootstrap.sh` invocation in its `$(package)_config_cmds` stage actually produced a binary called `b2`, which is run on the machine that's performing the build. This means that `b2` is a `native` package which is being built in an environment set up for the non-`native` package `boost`. This reveals a hidden unintended behavior in our `depends` build system: for linux->darwin cross builds, we use `gcc` for `native` packages, and `clang` for non-`native` packages. But `b2` was actually being built using `clang`, since it was being built in an environment set up for non-`native` packages. theuni you might be interested in taking a look ACKs for top commit: laanwj: Concept and code review ACKf190343c96Tree-SHA512: f8b728a34da4f0a9a985a819a5762f2fc2689ea24c7eba1d24d26dfbd4c59f202227c699b0a4069dab10b6329cf9f4c6dd95082685776ee43dd5f7b659acdef1
Bitcoin Core integration/staging tree
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.
For more information, as well as an immediately usable, binary version of the Bitcoin Core software, see https://bitcoincore.org/en/download/, or read the original whitepaper.
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, that are run automatically on the build server.
These tests can be run (if the test dependencies are installed) with: test/functional/test_runner.py
The Travis CI system makes 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.
Translators should also subscribe to the mailing list.
