This PR removes [end of life](https://endoflife.date/python) versions of Python from Spack. Specifically, this includes all versions of Python older than 3.7. See https://github.com/spack/spack/discussions/31824 for rationale. Deprecated in #32615. And #28003. For anyone using software that relies on Python 2, you have a few options: * Upgrade the software to support Python 3. The `3to2` tool may get you most of the way there, although more complex libraries may need manual tweaking. * Add Python 2 as an [external package](https://spack.readthedocs.io/en/latest/build_settings.html#external-packages). Many Python libraries do not support Python 2, but you may be able to add older versions that did once upon a time. * Use Spack 0.19. Spack 0.19 is the last release to officially support Python 3.6 and older * Create and maintain your own [custom repository](https://spack.readthedocs.io/en/latest/repositories.html). Basically, you would need a package for Python 2 and any other Python 2-specific libraries you need.

Subject: [PATCH] bpo-37415: Fix stdatomic.h header check for ICC compiler
|
|
|
|
Fix stdatomic.h header check for ICC compiler: the ICC implementation
|
|
lacks atomic_uintptr_t type which is needed by Python.
|
|
|
|
Test:
|
|
|
|
* atomic_int and atomic_uintptr_t types
|
|
* atomic_load_explicit() and atomic_store_explicit()
|
|
* memory_order_relaxed and memory_order_seq_cst constants
|
|
|
|
But don't test ATOMIC_VAR_INIT(): it's not used in Python.
