cbee1d70918b7c8e524c07f3da7049c3a1a2cbff depends: modernize clang flags (Cory Fields) 2a85857ce5cddd365353216960e2d5d76d6102b8 ci: disable false-positive warnings for now (Cory Fields) Pull request description: This is a cleaner and simpler alternative to #25098. Inspired by [this conversation](https://github.com/bitcoin/bitcoin/pull/27737#issuecomment-1562543301). The diff is large but the change itself is quite small. Fixes builds with llvm >= 11 in guix by working around the problem. As a bonus, this is much cleaner and more maintainable than what we had before. See the updated comment for more info. At a high level: rather than playing tricks and trying to work around clang's default includes, disable them and re-add what we want. ACKs for top commit: fanquake: ACK cbee1d70918b7c8e524c07f3da7049c3a1a2cbff - tested Guix and the depends cross-compile. Would like to move this along, to unblock #27676, which itself might be a blocker for #27897. Note that macOS might seem somewhat in flux for the moment, but once we finish the migration to LLVM Clang + LLD, things will be must simpler, and ultimately more maintainable.

CI Scripts
This directory contains scripts for each build step in each build stage.
Running a Stage Locally
Be aware that the tests will be built and run in-place, so please run at your own risk. If the repository is not a fresh git clone, you might have to clean files from previous builds or test runs first.
The ci needs to perform various sysadmin tasks such as installing packages or writing to the user's home directory. While it should be fine to run the ci system locally on you development box, the ci scripts can generally be assumed to have received less review and testing compared to other parts of the codebase. If you want to keep the work tree clean, you might want to run the ci system in a virtual machine with a Linux operating system of your choice.
To allow for a wide range of tested environments, but also ensure reproducibility to some extent, the test stage
requires bash, docker, and python3 to be installed. To install all requirements on Ubuntu, run
sudo apt install bash docker.io python3
To run the test stage with a specific configuration,
FILE_ENV="./ci/test/00_setup_env_arm.sh" ./ci/test_run_all.sh
Configurations
The test files (FILE_ENV) are constructed to test a wide range of
configurations, rather than a single pass/fail. This helps to catch build
failures and logic errors that present on platforms other than the ones the
author has tested.
Some builders use the dependency-generator in ./depends, rather than using
the system package manager to install build dependencies. This guarantees that
the tester is using the same versions as the release builds, which also use
./depends.
If no FILE_ENV has been specified or values are left out, 00_setup_env.sh
is used as the default configuration with fallback values.
It is also possible to force a specific configuration without modifying the file. For example,
MAKEJOBS="-j1" FILE_ENV="./ci/test/00_setup_env_arm.sh" ./ci/test_run_all.sh
The files starting with 0n (n greater than 0) are the scripts that are run
in order.
Cache
In order to avoid rebuilding all dependencies for each build, the binaries are cached and re-used when possible. Changes in the dependency-generator will trigger cache-invalidation and rebuilds as necessary.
