The smtp test server can be set via CPYTHON_TEST_SMTP_SERVER environment variable.
If not set, it uses the default value smtp.gmail.com
This is needed because the network I'm on filters access to
smtp.gmail.com resulting in a failing test.

Only treat '\n', '\r' and '\r\n' as line separators in re-folding the email
messages. Preserve control characters '\v', '\f', '\x1c', '\x1d' and '\x1e'
and Unicode line separators '\x85', '\u2028' and '\u2029' as is.
Remove unreliable tests on huge memory allocations:
* Remove test_maxcontext_exact_arith() of test_decimal.
Stefan Krah, test author, agreed on removing the test:
https://github.com/python/cpython/issues/114331#issuecomment-1925731273
* Remove test_constructor() tests of test_io.
Sam Gross suggests remove them:
https://github.com/python/cpython/pull/117809#pullrequestreview-2003889558
On Linux, depending how overcommit is configured, especially on Linux
s390x, a huge memory allocation (half or more of the full address
space) can succeed, but then the process will eat the full system
swap and make the system slower and slower until the whole system
becomes unusable.
Moreover, these tests had to be skipped when Python is built with
sanitizers.
We want code objects to use deferred reference counting in the
free-threaded build. This requires them to be tracked by the GC, so we
set `Py_TPFLAGS_HAVE_GC` in the free-threaded build, but not the default
build.
gh-117662 introduced some refleaks, or, rather, exposed some existing refleaks. The leaks are coming when test.support.os_helper is imported in a "legacy" interpreter. I've updated test.test_interpreters.utils to avoid importing os_helper, which fixes the leaks. I'll address the root cause separately.
Check `my_object_collected.wait()` in a loop to give the main thread a
chance to merge the reference count fields. Additionally, call
`my_object_collected.set()` in a background thread to avoid deadlocking
when the destructor is called asynchronously via the eval breaker
within the body of of `my_object_collected.wait()`.
Additionally, reduce the iterations for a few weakref tests that would
otherwise take a prohibitively long amount of time (> 1 hour) when TSAN
is enabled and the GIL is disabled.
Since 6258844c, paths that might not exist can be fed into pathlib's
globbing implementation, which will call `os.scandir()` / `os.lstat()` only
when strictly necessary. This allows us to drop an initial `self.is_dir()`
call, which saves a `stat()`.

rfc9110 obsoletes the earlier rfc 7231. This document also includes some
status codes that were previously only used for WebDAV and assigns more
generic names to these status codes.
ref: https://www.rfc-editor.org/rfc/rfc9110.html#name-changes-from-rfc-7231
- http.HTTPStatus.CONTENT_TOO_LARGE (413, previously
REQUEST_ENTITY_TOO_LARGE)
- http.HTTPStatus.URI_TOO_LONG (414, previously REQUEST_URI_TOO_LONG)
- http.HTTPStatus.RANGE_NOT_SATISFYABLE (416, previously
REQUEST_RANGE_NOT_SATISFYABLE)
- http.HTTPStatus.UNPROCESSABLE_CONTENT (422, previously
UNPROCESSABLE_ENTITY)
The new constants are added to http.HTTPStatus and the old constant names are
preserved for backwards compatibility.
References in documentation to the obsoleted rfc 7231 are updated
Replace use of `os.listdir()` with `os.scandir()`. Forgo setting `_drv`,
`_root` and `_tail_cached`, as these usually aren't needed. Use
`os.DirEntry.path` to set `_str`.
Don't bother calling `os.scandir()` to scan for literal pattern segments,
like `foo` in `foo/*.py`. Instead, append the segment(s) as-is and call
through to the next selector with `exists=False`, which signals that the
path might not exist. Subsequent selectors will call `os.scandir()` or
`os.lstat()` to filter out missing paths as needed.
Test signatures of all public builtins and methods of builtin classes
in modules builtins, types, sys, and several other modules (either
included in the list of standard builtin modules sys.builtin_module_names,
or providing a public interface for such modules).
Most builtins should have supported signatures, with few known exceptions.
When more builtins will be converted to Argument Clinic or support of
new signatures be implemented, they will be removed from the exception
lists.
This is similar to the situation with threading._DummyThread. The methods (incl. __del__()) of interpreters.Interpreter objects must be careful with interpreters not created by interpreters.create(). The simplest thing to start with is to disable any method that modifies or runs in the interpreter. As part of this, the runtime keeps track of where an interpreter was created. We also handle interpreter "refcounts" properly.
The free-threaded build does not currently support the combination of
single-phase init modules and non-isolated subinterpreters. Ensure that
`check_multi_interp_extensions` is always `True` for subinterpreters in
the free-threaded build so that importing these modules raises an
`ImportError`.
gh-16429 introduced support for an iterable of separators in
Stream.readuntil. Since bytes-like types are themselves iterable, this
can introduce ambiguities in deciding whether the argument is an
iterator of separators or a singleton separator. In gh-16429, only 'bytes'
was considered a singleton, but this will break code that passes other
buffer object types.
Fix it by only supporting tuples rather than arbitrary iterables.
Closes gh-117722.
Fall back to tp_call() for cases when arguments are passed by name.

Move `pathlib.Path.walk()` implementation into `glob._Globber`. The new
`glob._Globber.walk()` classmethod works with strings internally, which is
a little faster than generating `Path` objects and keeping them normalized.
The `pathlib.Path.walk()` method converts the strings back to path objects.
In the private pathlib ABCs, our existing subclass of `_Globber` ensures
that `PathBase` instances are used throughout.
Follow-up to #117589.
Move pathlib globbing implementation into a new private class: `glob._Globber`. This class implements fast string-based globbing. It's called by `pathlib.Path.glob()`, which then converts strings back to path objects.
In the private pathlib ABCs, add a `pathlib._abc.Globber` subclass that works with `PathBase` objects rather than strings, and calls user-defined path methods like `PathBase.stat()` rather than `os.stat()`.
This sets the stage for two more improvements:
- GH-115060: Query non-wildcard segments with `lstat()`
- GH-116380: Unify `pathlib` and `glob` implementations of globbing.
No change to the implementations of `glob.glob()` and `glob.iglob()`.
Moves the validation for invalid years in the C implementation of the `datetime` module into a common location between `fromisoformat` and `fromisocalendar`, which improves the error message and fixes a failed assertion when parsing invalid ISO 8601 years using one of the "ISO weeks" formats.

This prevents external cancellations of a task group's parent task to
be dropped when an internal cancellation happens at the same time.
Also strengthen the semantics of uncancel() to clear self._must_cancel
when the cancellation count reaches zero.

Most mutable data is protected by a striped lock that is keyed on the
referenced object's address. The weakref's hash is protected using the
weakref's per-object lock.
Note that this only affects free-threaded builds. Apart from some minor
refactoring, the added code is all either gated by `ifdef`s or is a no-op
(e.g. `Py_BEGIN_CRITICAL_SECTION`).
The worker thread may still be alive after it enqueues it's last result,
which can lead to a delay of 30 seconds after the test finishes. This
happens much more frequently in the free-threaded build with the GIL
disabled.
This changes run_workers.py to track of live workers by enqueueing a
`WorkerExited()` instance before the worker exits.
The test suite fetches the C recursion limit from the _testcapi
extension module. Test extension modules can be disabled using the
--disable-test-modules configure option.
- re-enable test_fcntl_64_bit on Linux aarch64, but disable it on all
Android ABIs
- use support.setswitchinterval in all relevant tests
- skip test_fma_zero_result on Android x86_64
- accept EACCES when calling os.get_terminal_size on Android
Replace tri-state `follow_symlinks` with boolean `recurse_symlinks` argument. The new argument controls whether symlinks are followed when expanding recursive `**` wildcards. The possible argument values correspond as follows:
follow_symlinks recurse_symlinks
=============== ================
False N/A
None False
True True
We therefore drop support for not following symlinks when expanding non-recursive pattern parts; it wasn't requested in the original issue, and it's a feature not found in any shells.
This makes the API a easier to grok by eliminating `None` as an option.
No news blurb as `follow_symlinks` was new in 3.13.
gh-116609: Ignore UTF-16 BOM in importlib.resources._functional tests
To test the `errors` argument, we read a UTF-16 file as UTF-8
with "backslashreplace" error handling. However, the utf-16
codec adds an endian-specific byte-order mark, so on big-endian
machines the expectation doesn't match the test file (which was
saved on a little-endian machine).
Use endswith to ignore the BOM.
Apply the following optimizations to `posixpath.realpath()`:
- Remove use of recursion
- Construct child paths directly rather than using `join()`
- Use `os.getcwd[b]()` rather than `abspath()`
- Use `startswith(sep)` rather than `isabs()`
- Use slicing rather than `split()`

Introduce a unified 16-bit backoff counter type (``_Py_BackoffCounter``),
shared between the Tier 1 adaptive specializer and the Tier 2 optimizer. The
API used for adaptive specialization counters is changed but the behavior is
(supposed to be) identical.
The behavior of the Tier 2 counters is changed:
- There are no longer dynamic thresholds (we never varied these).
- All counters now use the same exponential backoff.
- The counter for ``JUMP_BACKWARD`` starts counting down from 16.
- The ``temperature`` in side exits starts counting down from 64.
Add libclinic.clanguage module and move the following classes and
functions there:
* CLanguage
* declare_parser()
Add libclinic.codegen and move the following classes there:
* BlockPrinter
* BufferSeries
* Destination
Move the following functions to libclinic.function:
* permute_left_option_groups()
* permute_optional_groups()
* permute_right_option_groups()
This merges all `_CHECK_STACK_SPACE` uops in a trace into a single `_CHECK_STACK_SPACE_OPERAND` uop that checks whether there is enough stack space for all calls included in the entire trace.
I had meant to switch everything to InterpreterError when I added it a while back. At the time I missed a few key spots.
As part of this, I've added print-the-exception to _PyXI_InitTypes() and fixed an error case in `_PyStaticType_InitBuiltin().
This change gives a significant speedup, as the METH_FASTCALL calling
convention is now used. The following methods are adapted:
- str.count
- str.find
- str.index
- str.rfind
- str.rindex
Use the fully qualified type name in repr() of weakref.ref and
weakref.proxy types.
Fix a crash in proxy_repr() when the reference is dead.
Add also test_ref_repr() and test_proxy_repr().
These helpers make it easier to customize and inspect the config used to initialize interpreters. This is especially valuable in our tests. I found inspiration from the PyConfig API for the PyInterpreterConfig dict conversion stuff. As part of this PR I've also added a bunch of tests.

* Replace use of 'sys.maxsize' with direct computation of the stripped value.
* Extract has_comments as a dynamic property.
* Implement clean as a cached property.
* Model comment prefixes in the RawConfigParser within a prefixes namespace.
* Use a regular expression to search for the first match.
Avoids mutating variables and tricky logic and over-computing all of the starts when only the first is relevant.
This adds a stop the world pause to make the two functions thread-safe
when the GIL is disabled in the free-threaded build.
Additionally, the main test thread may call `sys._current_exceptions()` as
soon as `g_raised.set()` is called. The background thread may not yet reach
the `leave_g.wait()` line.
The tests are not reliable with the GIL disabled. In theory, they can
fail with the GIL enabled too, but the failures are much more likely
with the GIL disabled.
