Description

resolve: https://github.com/Azure/CLIPS/issues/987

get_latest_version_from_ame_storage finds the latest released versions of azure-cli, azure-cli-core and azure-cli-telemetry. It does this by fetching {package}/setup.py from the AME storage account and parsing the VERSION = "..." line. The packages have moved to pyproject.toml, so setup.py no longer exists in the repo.

Changes:

• Read version = "..." from {AME_STORAGE_BASE_URL}/{package}/pyproject.toml first.
• Fall back to the legacy setup.py (VERSION = "...") when pyproject.toml can't be fetched or has no version line. Only setup.py is in storage today, so this keeps az version / az upgrade working until the release pipeline uploads pyproject.toml. The fallback can be removed after that.
• Simplify the parsing: one regex over the response text instead of a line-by-line scan.
• Add unit tests in TestGetLatestVersionFromAmeStorage covering:
  • reading the version from pyproject.toml
  • falling back to setup.py on a 404
  • falling back when pyproject.toml has no version line
  • returning None when both requests fail

What changed in this PR

Updates Azure CLI’s latest-version lookup to support package metadata in pyproject.toml, while preserving compatibility with AME storage that still contains only setup.py.

Changes:

• Fetches pyproject.toml first and falls back to setup.py if fetching fails or no version is found.
• Replaces line-by-line parsing with a regex over the response text.
• Adds unit tests for successful lookup, fallback behavior, and request failures.

src/​azure-cli-core/​azure/​cli/​core/​tests/​test_util.py	Adds four unit tests covering version lookup and fallback behavior.
