./lang/python312, Interpreted, interactive, object-oriented programming language

[ CVSweb ] [ Homepage ] [ RSS ] [ Required by ] [ Add to tracker ]


Branch: CURRENT, Version: 3.12.8nb1, Package name: python312-3.12.8nb1, Maintainer: pkgsrc-users

Python is an interpreted, interactive, object-oriented
programming language that combines remarkable power with
very clear syntax. For an introduction to programming in
Python you are referred to the Python Tutorial. The
Python Library Reference documents built-in and standard
types, constants, functions and modules. Finally, the
Python Reference Manual describes the syntax and semantics
of the core language in (perhaps too) much detail.

Python's basic power can be extended with your own modules
written in C or C++. On most systems such modules may be
dynamically loaded. Python is also adaptable as an exten-
sion language for existing applications. See the internal
documentation for hints.

This package provides Python version 3.12.x.

Log message:
lang/python*: Use libreadline unconditionally.

libedit breaks some applications.  Maybe we can fix it later but for
now let's just go back to using libreadline unconditionally like we
did before.

PKGREVISION++ because this materially affects the build product -- it
built before this change but didn't work right for some applications.
(No change to platforms without libedit -- which is most non-NetBSD
platforms, probably -- but we don't have per-platform PKGREVISION, so
gotta bump it for everyone.)

No change to 2.7, 3.9, or 3.10 because they already use libreadline
unconditionally; respecting READLINE_TYPE is a new change in >=3.11
since April which broke applications.

trampoline frame, skip it. Patch by Victor Stinner.

gh-127182: Fix io.StringIO.__setstate__() crash, when None was passed as the \ 
first value.

gh-127217: Fix urllib.request.pathname2url() for paths starting with multiple \ 
slashes on Posix.

gh-127035: Fix shutil.which on Windows. Now it looks at direct match if and only \ 
if the command ends with a PATHEXT extension or X_OK is not in mode. Support \ 
extensionless files if “.” is in PATHEXT. Support PATHEXT extensions that \ 
end with a dot.

gh-127078: Fix issue where urllib.request.url2pathname() failed to discard an \ 
extra slash before a UNC drive in the URL path on Windows.

gh-126766: Fix issue where urllib.request.url2pathname() failed to discard any \ 
‘localhost’ authority present in the URL.

gh-126997: Fix support of STRING and GLOBAL opcodes with non-ASCII arguments in \

value is sys.maxsize.

gh-85168: Fix issue where urllib.request.url2pathname() and pathname2url() \

filesystem encoding and error handler.

gh-67877: Fix memory leaks when regular expression matching terminates abruptly, \ 
either because of a signal or because memory allocation fails.

gh-126789: Fixed the values of sysconfig.get_config_vars(), \ 
sysconfig.get_paths(), and their siblings when the site initialization happens \ 
after sysconfig has built a cache for sysconfig.get_config_vars().

gh-126188: Update bundled pip to 24.3.1

gh-126766: Fix issue where urllib.request.url2pathname() failed to discard two \ 
leading slashes introducing an empty authority section.

gh-126727: locale.nl_langinfo(locale.ERA) now returns multiple era description \ 
segments separated by semicolons. Previously it only returned the first segment \ 
on platforms with Glibc.

gh-126699: Allow collections.abc.AsyncIterator to be a base for Protocols.

gh-104745: Limit starting a patcher (from unittest.mock.patch() or \ 
unittest.mock.patch.object()) more than once without stopping it

gh-126595: Fix a crash when instantiating itertools.count with an initial count \ 
of sys.maxsize on debug builds. Patch by Bénédikt Tran.

gh-120423: Fix issue where urllib.request.pathname2url() mishandled Windows \ 
paths with embedded forward slashes.

gh-126565: Improve performances of zipfile.Path.open() for non-reading modes.

gh-126505: Fix bugs in compiling case-insensitive regular expressions with \ 
character classes containing non-BMP characters: upper-case non-BMP character \ 
did was ignored and the ASCII flag was ignored when matching a character range \ 
whose upper bound is beyond the BMP region.

gh-117378: Fixed the multiprocessing "forkserver" start method \ 
forkserver process to correctly inherit the parent’s sys.path during the \ 
importing of multiprocessing.set_forkserver_preload() modules in the same manner \ 
as sys.path is configured in workers before executing work items.

This bug caused some forkserver module preloading to silently fail to preload. \ 
This manifested as a performance degration in child processes when the sys.path \ 
was required due to additional repeated work in every worker.

It could also have a side effect of "" remaining in sys.path during \ 
forkserver preload imports instead of the absolute path from os.getcwd() at \ 
multiprocessing import time used in the worker sys.path.

The sys.path differences between phases in the child process could potentially \ 
have caused preload to import incorrect things from the wrong location. We are \ 
unaware of that actually having happened in practice.

gh-125679: The multiprocessing.Lock and multiprocessing.RLock repr values no \ 
longer say “unknown” on macOS.

gh-126476: Raise calendar.IllegalMonthError (now a subclass of IndexError) for \ 
calendar.month() when the input month is not correct.

gh-126489: The Python implementation of pickle no longer calls \ 
pickle.Pickler.persistent_id() for the result of persistent_id().

gh-126303: Fix pickling and copying of os.sched_param objects.

gh-126138: Fix a use-after-free crash on asyncio.Task objects whose underlying \ 
coroutine yields an object that implements an evil __getattribute__(). Patch by \ 
Nico Posada.

gh-126220: Fix crash in cProfile.Profile and _lsprof.Profiler when their \ 
callbacks were directly called with 0 arguments.

gh-126212: Fix issue where urllib.request.pathname2url() and url2pathname() \ 
removed slashes from Windows DOS drive paths and URLs.

gh-126205: Fix issue where urllib.request.pathname2url() generated URLs \ 
beginning with four slashes (rather than two) when given a Windows UNC path.

gh-126105: Fix a crash in ast when the ast.AST._fields attribute is deleted.

gh-126106: Fixes a possible NULL pointer dereference in ssl.

gh-126080: Fix a use-after-free crash on asyncio.Task objects for which the \ 
underlying event loop implements an evil __getattribute__(). Reported by \ 
Nico-Posada. Patch by Bénédikt Tran.

gh-126083: Fixed a reference leak in asyncio.Task objects when reinitializing \ 
the same object with a non-None context. Patch by Nico Posada.

gh-125984: Fix use-after-free crashes on asyncio.Future objects for which the \ 
underlying event loop implements an evil __getattribute__(). Reported by \ 
Nico-Posada. Patch by Bénédikt Tran.

gh-125969: Fix an out-of-bounds crash when an evil asyncio.loop.call_soon() \ 
mutates the length of the internal callbacks list. Patch by Bénédikt Tran.

gh-125966: Fix a use-after-free crash in asyncio.Future.remove_done_callback(). \ 
Patch by Bénédikt Tran.

gh-125789: Fix possible crash when mutating list of callbacks returned by \ 
asyncio.Future._callbacks. It now always returns a new copy in C implementation \ 
_asyncio. Patch by Kumar Aditya.

gh-124452: Fix an issue in email.policy.EmailPolicy.header_source_parse() and \ 
email.policy.Compat32.header_source_parse() that introduced spurious leading \ 
whitespaces into header values when the header includes a newline character \ 
after the header name delimiter (:) and before the value.

gh-125884: Fixed the bug for pdb where it can’t set breakpoints on functions \ 
with certain annotations.

gh-125355: Fix several bugs in argparse.ArgumentParser.parse_intermixed_args().

The parser no longer changes temporarily during parsing.
Default values are not processed twice.
Required mutually exclusive groups containing positional arguments are now supported.
The missing arguments report now includes the names of all required optional and \ 
positional arguments.
Unknown options can be intermixed with positional arguments in \ 
parse_known_intermixed_args().

conforming to the JSON specification.

gh-125660: Reject invalid unicode escapes for Python implementation of json.loads().

gh-125259: Fix the notes removal logic for errors thrown in enum initialization.

gh-125519: Improve traceback if importlib.reload() is called with an object that \ 
is not a module. Patch by Alex Waygood.

gh-125451: Fix deadlock when concurrent.futures.ProcessPoolExecutor shuts down \ 
concurrently with an error when feeding a job to a worker process.

gh-125422: Fixed the bug where pdb and bdb can step into the bottom caller frame.

debugging an empty file.

gh-53203: Fix time.strptime() for %c, %x and %X formats in many locales that use \ 
non-ASCII digits, like Persian, Burmese, Odia and Shan.

gh-125254: Fix a bug where ArgumentError includes the incorrect ambiguous option \ 
in argparse.

gh-61011: Fix inheritance of nested mutually exclusive groups from parent parser \ 
in argparse.ArgumentParser. Previously, all nested mutually exclusive groups \ 
lost their connection to the group containing them and were displayed as \ 
belonging directly to the parser.

gh-52551: Fix encoding issues in time.strftime(), the strftime() method of the \ 
datetime classes datetime, date and time and formatting of these classes. \ 
Characters not encodable in the current locale are now acceptable in the format \ 
string. Surrogate pairs and sequence of surrogatescape-encoded bytes are no \ 
longer recombinated. Embedded null character no longer terminates the format \ 
string.

gh-125118: Don’t copy arbitrary values to _Bool in the struct module.

gh-125069: Fix an issue where providing a pathlib.PurePath object as an \ 
initializer argument to a second PurePath object with a different flavour \ 
resulted in arguments to the former object’s initializer being joined by the \ 
latter object’s flavour.

gh-124969: Fix locale.nl_langinfo(locale.ALT_DIGITS) on platforms with glibc. \ 
Now it returns a string consisting of up to 100 semicolon-separated symbols (an \ 
empty string in most locales) on all Posix platforms. Previously it only \ 
returned the first symbol or an empty string.

gh-124958: Fix refcycles in exceptions raised from asyncio.TaskGroup and the \ 
python implementation of asyncio.Future

gh-53203: Fix time.strptime() for %c and %x formats in many locales: Arabic, \ 
Bislama, Breton, Bodo, Kashubian, Chuvash, Estonian, French, Irish, Ge’ez, \ 
Gurajati, Manx Gaelic, Hebrew, Hindi, Chhattisgarhi, Haitian Kreyol, Japanese, \ 
Kannada, Korean, Marathi, Malay, Norwegian, Nynorsk, Punjabi, Rajasthani, Tok \ 
Pisin, Yoruba, Yue Chinese, Yau/Nungon and Chinese.

gh-124917: Allow calling os.path.exists() and os.path.lexists() with keyword \ 
arguments on Windows. Fixes a regression in 3.12.4.

gh-124653: Fix detection of the minimal Queue API needed by the logging module. \ 
Patch by Bénédikt Tran.

gh-124858: Fix reference cycles left in tracebacks in asyncio.open_connection() \ 
when used with happy_eyeballs_delay

gh-124390: Fixed AssertionError when using asyncio.staggered.staggered_race() \ 
with asyncio.eager_task_factory.

gh-124651: Properly quote template strings in venv activation scripts.

gh-124594: All asyncio REPL prompts run in the same context. Contributed by \ 
Bartosz Sławecki.

gh-120378: Fix a crash related to an integer overflow in curses.resizeterm() and \ 
curses.resize_term().

gh-123884: Fixed bug in itertools.tee() handling of other tee inputs (a tee in a \ 
tee). The output now has the promised n independent new iterators. Formerly, the \ 
first iterator was identical (not independent) to the input iterator. This would \ 
sometimes give surprising results.

gh-123978: Remove broken time.thread_time() and time.thread_time_ns() on NetBSD.

gh-124008: Fix possible crash (in debug build), incorrect output or returning \ 
incorrect value from raw binary write() when writing to console on Windows.

gh-123370: Fix the canvas not clearing after running turtledemo clock.

gh-120754: Update unbounded read calls in zipfile to specify an explicit size \ 
putting a limit on how much data they may read. This also updates handling \ 
around ZIP max comment size to match the standard instead of reading comments \ 
that are one byte too long.

gh-70764: Fixed an issue where inspect.getclosurevars() would incorrectly \ 
classify an attribute name as a global variable when the name exists both as an \ 
attribute name and a global variable.

gh-119826: Always return an absolute path for os.path.abspath() on Windows.

gh-117766: Always use str() to print choices in argparse.

gh-101955: Fix SystemError when match regular expression pattern containing some \ 
combination of possessive quantifier, alternative and capture group.

gh-88110: Fixed multiprocessing.Process reporting a .exitcode of 1 even on \ 
success when using the "fork" start method while using a \ 
concurrent.futures.ThreadPoolExecutor.

gh-71936: Fix a race condition in multiprocessing.pool.Pool.

bpo-46128: Strip unittest.IsolatedAsyncioTestCase stack frames from reported \ 
stacktraces.

bpo-14074: Fix argparse metavar processing to allow positional arguments to have \ 
a tuple metavar.

IDLE

gh-122392: Increase currently inadequate vertical spacing for the IDLE browsers \ 
(path, module, and stack) on high-resolution monitors.

Documentation

gh-125277: Require Sphinx 7.2.6 or later to build the Python documentation. \ 
Patch by Adam Turner.
gh-125018: The importlib.metadata documentation now includes semantic \ 
cross-reference targets for the significant documented APIs. This means \ 
intersphinx references like importlib.metadata.version() will now work as \ 
expected.
gh-121277: Writers of CPython’s documentation can now use next as the version \ 
for the versionchanged, versionadded, deprecated directives.
gh-60712: Include the object type in the lists of documented types. Change by \ 
Furkan Onder and Martin Panter.
Core and Builtins
gh-113841: Fix possible undefined behavior division by zero in complex’s \ 
_Py_c_pow().
gh-126341: Now ValueError is raised instead of SystemError when trying to \ 
iterate over a released memoryview object.
gh-126066: Fix importlib to not write an incomplete .pyc files when a ulimit or \ 
some other operating system mechanism is preventing the write to go through \ 
fully.
gh-126139: Provide better error location when attempting to use a future \ 
statement with an unknown future feature.
gh-125008: Fix tokenize.untokenize() producing invalid syntax for double braces \ 
preceded by certain escape characters.
gh-123378: Fix a crash in the __str__() method of UnicodeError objects when the \ 
UnicodeError.start and UnicodeError.end values are invalid or out-of-range. \ 
Patch by Bénédikt Tran.
gh-116510: Fix a crash caused by immortal interned strings being shared between \ 
sub-interpreters that use basic single-phase init. In that case, the string can \ 
be used by an interpreter that outlives the interpreter that created and \ 
interned it. For interpreters that share obmalloc state, also share the interned \ 
dict with the main interpreter.
gh-118950: Fix bug where SSLProtocol.connection_lost wasn’t getting called \ 
when OSError was thrown on writing to socket.
gh-113570: Fixed a bug in reprlib.repr where it incorrectly called the repr \ 
method on shadowed Python built-in types.
gh-109746: If _thread.start_new_thread() fails to start a new thread, it deletes \ 
its state from interpreter and thus avoids its repeated cleanup on finalization.

C API

gh-113601: Removed debug build assertions related to interning strings, which \ 
were falsely triggered by stable ABI extensions.

Build

gh-89640: Hard-code float word ordering as little endian on WASM.
gh-89640: Improve detection of float word ordering on Linux when link-time \ 
optimizations are enabled.
