Backporting

Timeline

  • Immediate: patchset needed as soon as possible
  • Next Minor Stable Release: patchset that needs to be verified in nightly before backport
  • Eventually: patchset that needs to be verified in alpha before backport
  • No Backport (preferred): patchset for the next major stable

(Optional) Justification

  • Emergency security update: patchset fixes CVEs, 0-days, etc
  • Censorship event: patchset enables censorship circumvention
  • Critical bug-fix: patchset fixes a bug in core-functionality
  • Consistency: patchset which would make development easier if it were in both the alpha and release branches; developer tools, build system changes, etc
  • Sponsor required: patchset required for sponsor
  • Other: necessary to build all 128.4.0-based releases

Change Description

Downgrade to Python 3.9.x, which is the last major version that still supports the OpenSSL version our Debian containers have.

This is the less intrusive way to solve this problem for us.

We have some alternatives (see the issue), if we end up preferring those.

How Tested

Built a testbuild, and seen it succeeded (also, checked that the Python project log says the _ssl module is built successfully).
