presubmit has passed, so I'm landing this, although the build itself appears to be broken //cc @guidovranken |

I will look at it. |

The changes introduced here upgrade Python from 3.8 to 3.10.14 inside the base-builder and base-runner images. ### base-builder changes: Prior to these changes, base-builder compiled Python 3.8 from source using sources downloaded from the official release servers at https://www.python.org/ftp/python/. This updates the compiled version to 3.10.14 (the latest 3.10 release) instead. ### base-runner changes: Prior to these changes, base-runner installed Python 3.8 from the default apt repository provided by the Ubuntu 20.04 image it's based on. These apt repositories do not have a version of Python 3.10 available by default. This updates the base-runner to instead use a multi-stage build to copy the same Python interpreter compiled by the base-builder image into the runner image, which ensures both Python versions remain in-sync while saving build time by re-using a pre-built version. ## Motivation - Code coverage does not work on Python projects that use Python 3.10+ syntax, and will not work until this or similar changes are landed (see google#11419) - Upgrading the base-image to use Ubuntu 22.04 (which provides more recent Python versions via apt) has been stated as being unlikely to happen any time soon (see google#3290) - Many OSS-Fuzz integrated Python projects no longer support Python 3.8 and have resorted to implementing ad-hoc workarounds to upgrade to newer Python versions, including installing Python from the Dead Snakes PPA. - This leads to fragmentation and hard to debug issues. Maintenance is easier when everyone is using the same version without issue. - With [Python 3.8 reaching end of life soon (in 2024-10)][python- versions-EOL], it is likely that more Python projects will begin dropping support for 3.8, further increasing the number of broken builds and ad-hoc workarounds. - Previous attempts at upgrading Python have stalled. ## Known & Expected Issues Several project Dockerfiles and build scripts contain hard coded references to python3.8 file system paths, and many more have implanted ad-hoc workarounds to upgrade to newer Python versions than 3.8 (typically 3.9.) Additional changes are required to each of these projects to ensure they successfully build after this upgrade to Python 3.10. ### Fuzz Introspector Caveat Fuzz Introspector currently uses Python 3.9. While an upgrade to 3.10 is not expected to introduce any new issues, it was not tested on these changes and may require additional work. ## Possible Areas of Improvement Using the base-builder image in a multi-stage build to copy the pre- compiled Python into base-runner is effective, but feels like a workaround that may be introducing tech debt. A cleaner approach would be to extract the Python compilation into a discrete base image similar to how `base-clang` works, and use that as the multi-stage builder in images that need it. --- Fixes: - google#11419 Supersedes: - google#9532 - google#11420 [python-versions-EOL]: https://devguide.python.org/versions/
