See upstream [`cctools`](https://github.com/tpoechtrager/cctools-port/commits/973.0.1-ld64-609) and [`libtapi`](https://github.com/tpoechtrager/apple-libtapi/tree/1100.0.11). This should improve the possibility of Apple ARM cross-compilation in depends. This also removes our [patching out of pthreads usage](https://github.com/bitcoin/bitcoin/blob/master/depends/patches/native_cctools/ld64_disable_threading.patch) in `ld64`. There have been multiple changes since `ld64 450.3`, which have likely fixed the non-determinism we were working around. i.e from [InputFiles.cpp](https://opensource.apple.com/source/ld64/ld64-609/src/ld/InputFiles.cpp.auto.html): ```cpp // <rdar://problem/15002251> make implicit dylib order be deterministic by sorting by install_name std::sort(implicitDylibs.begin(), implicitDylibs.end(), DylibByInstallNameSorter()); ``` ```cpp // <rdar://problem/42675402> ld64 output is not deterministic due to dylib processing order std::sort(unprocessedDylibs.begin(), unprocessedDylibs.end(), [](const ld::dylib::File* lhs, const ld::dylib::File* rhs) { return strcmp(lhs->path(), rhs->path()) < 0; }); ``` Guix Build: ```bash find guix-build-$(git rev-parse --short=12 HEAD)/output/ -type f -print0 | env LC_ALL=C sort -z | xargs -r0 sha256sum f6c3817b8fe5f7370299d1ae2533e4a3acd313ba9f9aa8d423a8956117e52dd5 guix-build-a5550f877a2c/output/dist-archive/bitcoin-a5550f877a2c.tar.gz 4954dcf563c2d496b8d9fecd48f8e3f7fba2f319ffa254a5bc8ee12cfee6acf0 guix-build-a5550f877a2c/output/x86_64-apple-darwin18/bitcoin-a5550f877a2c-osx-unsigned.dmg 8f6095b445c7f1a8e6accd86bb7f0696d5849402084927d2b726b7d557831c3a guix-build-a5550f877a2c/output/x86_64-apple-darwin18/bitcoin-a5550f877a2c-osx-unsigned.tar.gz cc40f25477b4defc1617ae694313d80f307ddf6742fe6cc85c6bc0e215ef8be0 guix-build-a5550f877a2c/output/x86_64-apple-darwin18/bitcoin-a5550f877a2c-osx64.tar.gz ``` Gitian Build: ```bash Generating report 506a8abdefe559999b43dd9f14905b9b2b5a3363b1cd013d45ae47acc1f7ef6c bitcoin-a5550f877a2c-osx-unsigned.dmg f606997f74026dd12d110d683c6f116b40df324836904ef507dd7ac787e6ebe2 bitcoin-a5550f877a2c-osx-unsigned.tar.gz 5b495ef15f2c3260c2950921b61326912a9bf533cccd51e13818809fd225489e bitcoin-a5550f877a2c-osx64.tar.gz f6c3817b8fe5f7370299d1ae2533e4a3acd313ba9f9aa8d423a8956117e52dd5 src/bitcoin-a5550f877a2c.tar.gz 9eb0221e962d2839770963bd03c6c9e98e8bf3078566bee2ae42f06233a710fa bitcoin-core-osx-22-res.yml Done. ``` ACKs for top commit: hebasto: ACKa5550f877aTree-SHA512: 504c4b0f9cd3b939714a322298320c5bde07e9356a48a9a000060b36f8dce4d6134ed60c3a5188810476a28ec5b108733eabbc6fb8053231b9ea8a494cc91b12

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.
