James Bennett pointed out that "package signing" is widely misunderstood
as referring specifically to end-to-end signing with individual
publisher keys, rather than to metdata signing in general.
This updates the title and abstract to instead use the term "signed
repository metadata", and also updates a few other sections that
still gave the impression that implementing PEP 458 would be
enough to give the full end-to-end signing support that is actually
covered in PEP 480.
Also removes the exec() and eval() caveats on the reference implementation
(those have been migrated now, albeit not using a code structure that we
would genuinely want to merge).
* Rename __parameters__ to __args__, for typing.py compatibility
* Genericize, re.{Pattern,Match} and io.IO
* list != list[int], but list[int] == list[int] (and list[str] != list[int])
* Add a lazy __parameters__ that contains the unique type vars in __args__ (also for typing.py compatibility)
* make dict[str][str] fail, but dict[T, str][int] return dict[int, str]
* expose proxy type as types.GenericAlias
* Link to implementation
* Explicitly state that pickling or copying should work
* PEP 376: Use ReST code syntax for literal characters
Without markup, it is very easy to confuse code with adjoining
punctuation.
* PEP 376: Use ReST syntax for code, rather than Markdown syntax
* Made various edits and clarifications to the pep including:
* letting the PSF appoint offline key holders
* moving content from abstract to motivation to make the abstract more succinct
* updating the threat model
* resolving some minor inconsistencies
* add link to cncf blog post
* PEP 458: use "OpenPGP" instead of "GPG". The signature format is OpenPGP. Other
OpenPGP implementations exist aside from gpg, the OpenPGP tool from the GnuPG project.
* PEP 611: relax hard limits and make 1 million a soft limit. Include recursion depth in limits.
* Reorganize part of motivation to account for soft vs. hard limits. Add qualification about recursion depth.
* Add non-goals section to clarify that this PEP does not remove support for GPG signatures.
* Update pep-0458.txt

- Remove the MRO walker, PyType_DefiningTypeFromSlotFunc, as it was
found it can give wrong results when a type's special methods are
changed (which can be done from Python code).
Solving the issue is deferred to a future PEP (and/or perhaps a
private CPython function).
- Split public C-API from CPython implementation details. It turns out
that alternate C-API implementations have grown more important
since 2016, if only for experimenting with possible optimizations.
- Add potentially confusing terms "Defining Class" and "C-API" to the
terminology section.
- Mention that ht_module is not inherited by subclasses.
- Remove modules to be ported initially: zipimport (since rewritten
in Python), _io and _cvs (need module state from slot methods).
* Mention __class__ cell, expand slot methods in Future extensions
And fix a typo.
Add subsection to section "Managing Future Changes to the Update
Process" that explains how to transition from an old (e.g. because
it has become weak) to a new (e.g. stronger) hashing algorithm
without disrupting client workflows.
* report TypeError rather than SystemError when bad types are passed
to new APIs
* add PyType_FromModuleAndSpec to the list of new functions
* wrap text at 80 columns
* add C API docs links for thread-local storage and context variables
* note in abstract that only the initial state lookup from slots is
inherently slow, with subsequent lookups being amenable to caching
* other minor wording tweaks
When updating the PEP to specify independent snapshots for locals()
at function scope, I missed this reference to the old semantics
that returned a direct reference to the dynamic internal snapshot.
* Switch to independent snapshots at function scope
* New public C API, PyEval_Get_PyLocals(), that matches the updated locals() builtin
* At function scope, PyEval_GetLocals() returns the internal shared mapping from inside the proxy (returning a borrowed reference means this API can't offer the new independent snapshot semantics)
