bpo-34206: Improve docs and test coverage for pre-init functions (#8023)
- move the Py_Main documentation from the very high level API section
  to the initialization and finalization section
- make it clear that it encapsulates a full Py_Initialize/Finalize
  cycle of its own
- point out that exactly which settings will be read and applied
  correctly when Py_Main is called after a separate runtime
  initialization call is version dependent
- be explicit that Py_IsInitialized can be called prior to
  initialization
- actually test that Py_IsInitialized can be called prior to
  initialization
- flush stdout in the embedding tests that run code so it appears
  in the expected order when running with "-vv"
- make "-vv" on the subinterpreter embedding tests less spammy

gh-69998: Fix decoding error in locale.nl_langinfo() (GH-124963)
The function now sets temporarily the LC_CTYPE locale to the locale
of the category that determines the requested value if the locales are
different and the resulting string is non-ASCII.
This temporary change affects other threads.

gh-70870: Clarify dual usage of 'free variable' (#122545)
The term "free variable" has unfortunately become genuinely
ambiguous over the years (presumably due to the names of
some relevant code object instance attributes).

While we can't eliminate that ambiguity at this late date, we can
at least alert people to the potential ambiguity by describing
both the formal meaning of the term and the common
alternative use as a direct synonym for "closure variable".

gh-120762: make_ssl_certs: Don't set extensions for the temporary CSR (GH-125045)
gh-120762: make_ssl_certs: Don't set extensions for the CSR

`openssl req` fails with openssl 3.2.2 because the config line

    authorityKeyIdentifier = keyid:always,issuer:always

is not supported for certificate signing requests (since the issuing
certificate authority is not known).

David von Oheimb, the OpenSSL dev that made the change, commented in:
https://github.com/openssl/openssl/issues/22966#issuecomment-1858396738 :

> This problem did not show up in older OpenSSL versions because of a bug:
> the `req` app ignored the `-extensions` option unless `-x505` is given,
> which I fixed in https://github.com/openssl/openssl/pull/16865.

(I assume `-x505` is a typo for `-x509`.)

In our `make_cert_key` function:

If `sign` is true:
- We don't pass `-x509` to `req`, so in this case it should be safe to
  omit the `-extensions` argument. (Old OpenSSL ignores it, new OpenSSL
  fails on it.)
- The extensions are passed to the `ca` call later in the function.
  There they take effect, and `authorityKeyIdentifier` is valid.

If `sign` is false, this commit has no effect except rearranging the
CLI arguments.

GH-119866: Spill the stack around escaping calls. (GH-124392)
* Spill the evaluation around escaping calls in the generated interpreter and JIT. 

* The code generator tracks live, cached values so they can be saved to memory when needed.

* Spills the stack pointer around escaping calls, so that the exact stack is visible to the cycle GC.

gh-117151: increase default buffer size of shutil.copyfileobj() to 256k. (GH-119783)
* gh-117151: increase default buffer size of shutil.copyfileobj() to 256k.

it was set to 16k in the 1990s.
it was raised to 64k in 2019. the discussion at the time mentioned another 5% improvement by raising to 128k and settled for a very conservative setting.

it's 2024 now, I think it should be revisited to match modern hardware. I am measuring 0-15% performance improvement when raising to 256k on various types of disk. there is no downside as far as I can tell.

this function is only intended for sequential copy of full files (or file like objects). it's the typical use case that benefits from larger operations.

for reference, I came across this function while trying to profile pip that is using it to copy files when installing python packages.

* add news

gh-124889: Remove redundant artificial rules in PEG parser (#124893)
Cache in C PEG-generator reworked:
we save artificial rules in cache by Node string representation as a key instead of Node object itself.
As a result total count of artificial rules in parsers.c is lowered from 283 to 170.
More natural number ordering is used for the names of artificial rules.

Auxiliary method CCallMakerVisitor._generate_artificial_rule_call is added.
Its purpose is abstracting work with artificial rules cache.

Explicit using of "is_repeat1" kwarg is added to visit_Repeat0 and visit_Repeat1 methods.
Its slightly improve code readabitily.
