gh-151378: Fix unbounded memory growth when recording binary and the thread is sleeping (GH-152089)
(cherry picked from commit 639a5525fb)
Co-authored-by: Maurycy Pawłowski-Wieroński <[email protected]>
An abruptly closed empty comment ("<!-->" or "<!--->") no longer extends
up to a later "-->" in the same feed() call.
test_htmlparser now also feeds each string source as a single chunk, in
addition to one character at a time, to exercise different input buffering.

gh-150579: use lazy imports for concurrent.futures (GH-150585)
This module has a manual lazy import hack using `__getattr__`. Now that lazy imports exist and cannot be disabled, this could use lazy imports instead.
Key differences: this will now show up in sys.lazy_modules when accessed. Error messages should be a bit better without the wrapper `__getattr__` involved. That's the only differences I can think of.

gh-83386: Enable test_hang_gh83386 for ProcessPoolExecutor (GH-152976)
The hang this test guards against (interpreter exit after
shutdown(wait=False) with running futures) was fixed for
ProcessPoolExecutor by the executor management rewrite years ago, but
the test still skipped it citing the issue. The skip also hid a latent
NameError in the subprocess template, which only selects a start method
in the process pool variants; rewrite it to use the same
mp_context=get_context() shape as the sibling templates. Remove a stale
comment claiming ProcessPoolExecutor often hangs with wait=False.

gh-115634: Fix ProcessPoolExecutor deadlock with max_tasks_per_child (GH-140900)
The idle worker semaphore counts task completions, not idle workers, so
it can hold a stale token released by a worker that later exited upon
reaching its max_tasks_per_child limit. The worker replacement path
consumed such tokens and skipped spawning a replacement, deadlocking
the remaining queued tasks once no workers were left.
Replace dead workers based on len(self._processes) without consulting
the semaphore. The submit() path is unchanged, preserving on-demand
spawning and idle worker reuse.
Replace the documentation note added in GH-140897 with a versionchanged
entry now that the bug is fixed.
Based on a fix proposed by Tabrez Mohammed.

gh-152680: Detect virtualization on Windows in pythoninfo (GH-152824)
Use WMI to detect virtualization on Windows.
Replace wmic command with _wmi module to get the operating system caption and
version.
The wmic tool is deprecated since January 2024:
https://techcommunity.microsoft.com/blog/windows-itpro-blog/wmi-command-line-wmic-utility-deprecation-next-steps/4039242
For example, it's no longer installed in Windows images on GitHub
Action.
Fix also run_command(): no longer try to spawn a subprocess if the
platform doesn't support subprocess. It avoids logging run_command()
errors.

Add coverage tests for the IMAP4 command methods and their UID variants
(SELECT, CREATE, COPY, STORE, FETCH, SEARCH, SORT, THREAD, DELETE,
RENAME, SUBSCRIBE, UNSUBSCRIBE, LIST, STATUS, the ACL and quota
commands, ANNOTATION, PROXYAUTH and ENABLE), plus test helpers
(splitargs, parse_sequence_set, make_simple_handler) and per-command
argument capture in the test server.

imaplib fetched the server capabilities only once, at connection time.
They are now also refreshed after a successful LOGIN or AUTHENTICATE,
from the CAPABILITY response the server sent or, if it sent none, by
querying it. This lets methods such as enable() see capabilities added
after login, for example ENABLE on Gmail (gh-103451).
Capabilities advertised in the server greeting are now used too, saving
a redundant CAPABILITY command.
