A bump will allow new code to use new python 3.9 features. For reference: * https://packages.debian.org/bullseye/python3 * https://packages.ubuntu.com/focal/python3.9 * FreeBSD 12/13 also ships with 3.9 * CentOS-like 8/9 also ships with 3.9 (and 3.11) * OpenSuse Leap also ships with 3.9 (and 3.11) https://software.opensuse.org/package/python311-base This is for Bitcoin Core 27.0 in 2024 (next year), not the soon upcoming 26.0 next month.

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
It is recommended to run the ci system in a clean env. To run the test stage with a specific configuration,
env -i HOME="$HOME" PATH="$PATH" USER="$USER" bash -c 'FILE_ENV="./ci/test/00_setup_env_arm.sh" ./ci/test_run_all.sh'
Configurations
The test files (FILE_ENV) are constructed to test a wide range of
configurations, rather than a single pass/fail. This helps to catch build
failures and logic errors that present on platforms other than the ones the
author has tested.
Some builders use the dependency-generator in ./depends, rather than using
the system package manager to install build dependencies. This guarantees that
the tester is using the same versions as the release builds, which also use
./depends.
It is also possible to force a specific configuration without modifying the file. For example,
env -i HOME="$HOME" PATH="$PATH" USER="$USER" bash -c '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.
