./lang/python37, Interpreted, interactive, object-oriented programming language

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


Branch: CURRENT, Version: 3.7.7, Package name: python37-3.7.7, 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 3.7.x.

python37: updated to 3.7.7

Python 3.7.7 final

Library
bpo-13487: Avoid a possible “RuntimeError: dictionary changed size during \ 
iteration” from inspect.getmodule() when it tried to loop through sys.modules.
Documentation
bpo-17422: The language reference no longer restricts default class namespaces \ 
to dicts only.

Python 3.7.7 release candidate 1

Security
bpo-39401: Avoid unsafe load of api-ms-win-core-path-l1-1-0.dll at startup on \ 
Windows 7.
Core and Builtins
bpo-39776: Fix race condition where threads created by PyGILState_Ensure() could \ 
get a duplicate id.

This affects consumers of tstate->id like the contextvar caching machinery, \ 
which could return invalid cached objects under heavy thread load (observed in \ 
embedded scenarios).
bpo-39778: Fixed a crash due to incorrect handling of weak references in \ 
collections.OrderedDict classes. Patch by Pablo Galindo.
bpo-39382: Fix a use-after-free in the single inheritance path of issubclass(), \ 
when the __bases__ of an object has a single reference, and so does its first \ 
item. Patch by Yonatan Goldschmidt.
bpo-39606: Fix regression caused by fix for bpo-39386, that prevented calling \ 
aclose on an async generator that had already been closed or exhausted.
bpo-39510: Fix segfault in readinto() method on closed BufferedReader.
bpo-39453: Fixed a possible crash in list.__contains__() when a list is changed \ 
during comparing items. Patch by Dong-hee Na.
bpo-39427: Document all possibilities for the -X options in the command line \ 
help section. Patch by Pablo Galindo.
bpo-39421: Fix possible crashes when operating with the functions in the heapq \ 
module and custom comparison operators.
bpo-39386: Prevent double awaiting of async iterator.
bpo-38588: Fix possible crashes in dict and list when calling \ 
PyObject_RichCompareBool().
bpo-39031: When parsing an “elif” node, lineno and col_offset of the node \ 
now point to the “elif” keyword and not to its condition, making it \ 
consistent with the “if” node. Patch by Lysandros Nikolaou.
bpo-38610: Fix possible crashes in several list methods by holding strong \ 
references to list elements when calling PyObject_RichCompareBool().
Library
bpo-39794: Add –without-decimal-contextvar build option. This enables a \ 
thread-local rather than a coroutine local context.
bpo-39769: The compileall.compile_dir() function’s ddir parameter and the \ 
compileall command line flag -d no longer write the wrong pathname to the \ 
generated pyc file for submodules beneath the root of the directory tree being \ 
compiled. This fixes a regression introduced with Python 3.5.
bpo-30566: Fix IndexError when trying to decode an invalid string with punycode \ 
codec.
bpo-39649: Remove obsolete check for __args__ in bdb.Bdb.format_stack_entry.
bpo-27657: The original fix for bpo-27657, “Fix urlparse() with numeric \ 
paths” (GH-16839) included in 3.7.6, inadvertently introduced a behavior \ 
change that broke several third-party packages relying on the original undefined \ 
parsing behavior. The change is reverted in 3.7.7, restoring the behavior of \ 
3.7.5 and earlier releases.
bpo-21016: The pydoc and trace modules now use the sysconfig module to get the \ 
path to the Python standard library, to support uncommon installation path like \ 
/usr/lib64/python3.9/ on Fedora. Patch by Jan Matějek.
bpo-39548: Fix handling of header in urllib.request.AbstractDigestAuthHandler \ 
when the optional qop parameter is not present.
bpo-39450: Striped whitespace from docstring before returning it from \ 
unittest.case.shortDescription().
bpo-39493: Mark typing.IO.closed as a property
bpo-39485: Fix a bug in unittest.mock.create_autospec() that would complain \ 
about the wrong number of arguments for custom descriptors defined in an \ 
extension module returning functions.
bpo-39430: Fixed race condition in lazy imports in tarfile.
bpo-39389: Write accurate compression level metadata in gzip archives, rather \ 
than always signaling maximum compression.
bpo-39274: bool(fraction.Fraction) now returns a boolean even if (numerator != \ 
0) does not return a boolean (ex: numpy number).
bpo-39242: Updated the Gmane domain from news.gmane.org to news.gmane.io which \ 
is used for examples of NNTP news reader server and nntplib tests.
bpo-39152: Fix ttk.Scale.configure([name]) to return configuration tuple for \ 
name or all options. Giovanni Lombardo contributed part of the patch.
bpo-39198: If an exception were to be thrown in Logger.isEnabledFor (say, by \ 
asyncio timeouts or stopit) , the logging global lock may not be released \ 
appropriately, resulting in deadlock. This change wraps that block of code with \ 
try...finally to ensure the lock is released.
bpo-39191: Perform a check for running loop before starting a new task in \ 
loop.run_until_complete() to fail fast; it prevents the side effect of new task \ 
spawning before exception raising.
bpo-38871: Correctly parenthesize filter-based statements that contain lambda \ 
expressions in mod:lib2to3. Patch by Dong-hee Na.
bpo-39142: A change was made to logging.config.dictConfig to avoid converting \ 
instances of named tuples to ConvertingTuple. It’s assumed that named tuples \ 
are too specialised to be treated like ordinary tuples; if a user of named \ 
tuples requires ConvertingTuple functionality, they will have to implement that \ 
themselves in their named tuple class.
bpo-38971: Open issue in the BPO indicated a desire to make the implementation \ 
of codecs.open() at parity with io.open(), which implements a try/except to \ 
assure file stream gets closed before an exception is raised.
bpo-39057: urllib.request.proxy_bypass_environment() now ignores leading dots \ 
and no longer ignores a trailing newline.
bpo-39056: Fixed handling invalid warning category in the -W option. No longer \ 
import the re module if it is not needed.
bpo-39055: base64.b64decode() with validate=True raises now a binascii.Error if \ 
the input ends with a single \n.
bpo-38878: Fixed __subclasshook__ of os.PathLike to return a correct result upon \ 
inheritence. Patch by Bar Harel.
bpo-35182: Fixed Popen.communicate() subsequent call crash when the child \ 
process has already closed any piped standard stream, but still continues to be \ 
running. Patch by Andriy Maletsky.
bpo-38473: Use signature from inner mock for autospecced methods attached with \ 
unittest.mock.attach_mock(). Patch by Karthikeyan Singaravelan.
bpo-38293: Add copy.copy() and copy.deepcopy() support to property() objects.
bpo-37953: In typing, improved the __hash__ and __eq__ methods for ForwardReferences.
bpo-36406: Handle namespace packages in doctest. Patch by Karthikeyan Singaravelan.
Documentation
bpo-13790: Change ‘string’ to ‘specification’ in format doc.
bpo-39530: Fix misleading documentation about mixed-type numeric comparisons.
bpo-17422: The language reference now specifies restrictions on class \ 
namespaces. Adapted from a patch by Ethan Furman.
bpo-39654: In pyclbr doc, update ‘class’ to ‘module’ where appropriate \ 
and add readmodule comment. Patch by Hakan Çelik.
bpo-39392: Explain that when filling with turtle, overlap regions may be left \ 
unfilled.
bpo-39381: Mention in docs that asyncio.get_event_loop() implicitly creates new \ 
event loop only if called from the main thread.
bpo-38918: Add an entry for __module__ in the “function” & “method” \ 
sections of the inspect docs types and members table
bpo-3530: In the ast module documentation, fix a misleading NodeTransformer \ 
example and add advice on when to use the fix_missing_locations function.
Tests
bpo-38546: Fix test_ressources_gced_in_workers() of test_concurrent_futures: \ 
explicitly stop the manager to prevent leaking a child process running in the \ 
background after the test completes.
Build
bpo-39144: The ctags and etags build targets both include Modules/_ctypes and \ 
Python standard library source files.
Windows
bpo-38597: distutils will no longer statically link vcruntime140.dll when a \ 
redistributable version is unavailable. All future releases of CPython will \ 
include a copy of this DLL to ensure distributed extensions can continue to \ 
load.
bpo-38380: Update Windows builds to use SQLite 3.31.1
bpo-39439: Reduce overhead when using multiprocessing in a Windows virtual \ 
environment
bpo-39185: The build.bat script has additional options for very-quiet output \ 
(-q) and very-verbose output (-vv)
macOS
bpo-38380: Update macOS builds to use SQLite 3.31.1
IDLE
bpo-39781: Selecting code context lines no longer causes a jump.
bpo-39663: Add tests for pyparse find_good_parse_start().
bpo-39600: In the font configuration window, remove duplicated font names.
bpo-30780: Add remaining configdialog tests for buttons and highlights and keys tabs.
bpo-39388: IDLE Settings Cancel button now cancels pending changes
bpo-39050: Make IDLE Settings dialog Help button work again.
bpo-34118: Tag memoryview, range, and tuple as classes, the same as list, \ 
etcetera, in the library manual built-in functions list.
bpo-38792: Close an IDLE shell calltip if a KeyboardInterrupt or shell restart \ 
occurs. Patch by Zackery Spytz.
bpo-32989: Add tests for editor newline_and_indent_event method. Remove dead \ 
code from pyparse find_good_parse_start method.
