The Ubuntu and Debian release wiki pages added in https://gerrit-review.googlesource.com/c/git-repo/+/649983 only list distro release and EOL dates, not which versions of Python, Git, or OpenSSH shipped in each distro release. Add Repology package version links alongside the distro release pages in python-support.md and requirements.json so maintainers can check which versions shipped across historical Ubuntu and Debian releases. Bug: 575551885 Change-Id: Ib256fd9b364074b52d3e15d185af519d8376cb28 Reviewed-on: https://gerrit-review.googlesource.com/c/git-repo/+/650868 Reviewed-by: Gavin Mak <gavinmak@google.com> Tested-by: Brian Gan <brgan@google.com> Commit-Queue: Brian Gan <brgan@google.com>

# This file declares various requirements for this version of repo. The
|
|
# launcher script will load it and check the constraints before trying to run
|
|
# us. This avoids issues of the launcher using an old version of Python (e.g.
|
|
# 3.5) while the codebase has moved on to requiring something much newer (e.g.
|
|
# 3.8). If the launcher tried to import us, it would fail with syntax errors.
|
|
|
|
# This is a JSON file with line-level comments allowed.
|
|
|
|
# Always keep backwards compatibility in mine. The launcher script is robust
|
|
# against missing values, but when a field is renamed/removed, it means older
|
|
# versions of the launcher script won't be able to enforce the constraint.
|
|
|
|
# When requiring versions, always use lists as they are easy to parse & compare
|
|
# in Python. Strings would require futher processing to turn into a list.
|
|
|
|
# Version constraints should be expressed in pairs: soft & hard. Soft versions
|
|
# are when we start warning users that their software too old and we're planning
|
|
# on dropping support for it, so they need to start planning system upgrades.
|
|
# Hard versions are when we refuse to work the tool. Users will be shown an
|
|
# error message before we abort entirely.
|
|
|
|
# When deciding whether to upgrade a version requirement, check out what
|
|
# versions major distros (e.g. Ubuntu LTS & Debian stable) ship and when they
|
|
# go EOL to see who will be impacted:
