The `main_path` parameter was renamed `init_main_from_name`, update the
forkserver code accordingly.  This was leading to slower startup times when people
were trying to preload the main module.

fix potential hang.

It can happen that the child crashes right in the beginning for whatever reason. In this case, the parent will hang when writing into the pipe, because the child fd is not closed yet.

The normal pattern is to close the child fds right after the child proc is forked/executed/spawned, so when the child dies, then also the pipes will be closed, and there will be no hang (the parent gets SIGPIPE instead).

R. David Murray [Sat, 6 Sep 2025 19:01:11 +0000 (15:01 -0400)] 
gh-90548: Allow Alpine/MUSL to pass test_c_locale_coercion. (GH-134454)

Like cygwin, MUSL defaults to utf-8 if no variables are set.  I have no
idea if the existing tests pass on cygwin, but I made the modifications
such that I shouldn't break it if is.  The additional checks needed for
MUSL are guarded by DEFAULT_LOCALE_IS_C being False.  Based on this
flag, we expect utf-8 for the encodings and no coercion message, as
long as LC_ALL is not set to C.  (That looks like a bit of an issue with
the test structure, but I'm not going to attempt to "fix" that.)
DEFAULT_ENCODING is intentionally not given a default since it is only
used when DEFAULT_LOCALE_IS_C is False, and if you use the flag you'll
need to set it.

After reading through issue 30672, looking at the source, and running a
test on Android, I *think* the current situation is that coercion will
be done if the local is set to POSIX regardless of platform.  However,
if the platform doesn't make POSIX equivalent to C, the encodings when
coercion is disabled will not be the same as for C (it is utf-8 on
android, for example).  This means the tests would fail if POSIX were
added unconditionally to the EXPECTED_C_LOCALE_EQUIVALENTS as envisioned
in the issue.  This *could* be fixed with another flag, but I'm not sure
it is worth the effort.  I'm not even sure Python is behaving optimally
in this case (assuming my analysis is correct).  So I just altered the
comment and add POSIX if and only if the platform is linux.

Cody Maloney [Wed, 3 Sep 2025 09:49:59 +0000 (02:49 -0700)] 
gh-138013: Remove `test_io` load_tests namespace manipulation (#138366)

Reduce what happens in `load_tests` so that the next change,
moving the `Buffered*` tests to `test_bufferdio` is purely mechanical
movement and updating imports.

This adds two classes, one per I/O implementation, to act as dispatch to
the implementation-specific mocks as well as module members. Previously
the mappings CTestCase and PyTestCase provide were injected directly
during `load_tests`.

CTestCase and PyTestCase inherit from `unittest.TestCase` so when the
split happens default test discovery will work for the classes in
`test_bufferedio`. `test_general` keeps a manual test list for this
refactoring; some of the tests (ex. `ProtocolsTest`) aren't currently
run and fixing that + helpers to not be picked up is out of my current
scope.

CTestCase and PyTestCase have an `io` class member which points to the
implementation meaning that can be removed from individual test cases
which now inherit from them.

This code is picking up `MockRawIO` which is defined globally in the
module but these should use the mock specific to the I/O implementation
being tested.

gh-138013: Move I/O tests to test_io (#138365)

Centralize `io` tests into the `test_io` module so they are easier to
find and work on. This will make it easier to split `test_general` which
takes 30+ seconds in a debug build on my machine.

This renames `test_bufio` to be `test_bufferedio` so that it matches
the implementation file name (`bufferedio.c`).

Validation performed:
Tests are run in parallel after change:

```bash
./python.exe -m test test_io  -uall,largefile,extralargefile -M12G -j8
```

Docstring reformat in `test_io/__init__.py` looks reasonable:

```python
>>> import test.test_io
>>> help(test.test_io)
```
