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

Branch: CURRENT, Version: 3.7.2, Package name: python37-3.7.2, 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 3.7.2

Python 3.7.2 final

- bpo-31715: Associate .mjs file extension with application/javascript MIME Type.

- bpo-35499: make profile-opt no longer replaces CFLAGS_NODIST with CFLAGS. It \ 
now adds profile-guided optimization (PGO) flags to CFLAGS_NODIST: existing \ 
CFLAGS_NODIST flags are kept.
- bpo-35257: Avoid leaking the linker flags from Link Time Optimizations (LTO) \ 
into distutils when compiling C extensions.

- bpo-35259: Conditionally declare Py_FinalizeEx() (new in 3.6) based on \ 

Python 3.7.2 release candidate 1

- bpo-34812: The -I command line option (run Python in isolated mode) is now \ 
also copied by the multiprocessing and distutils modules when spawning child \ 
processes. Previously, only -E and -s options (enabled by -I) were copied.
- bpo-34791: The xml.sax and xml.dom.domreg no longer use environment variables \ 
to override parser implementations when sys.flags.ignore_environment is set by \ 
-E or -I arguments.

Core and Builtins
- bpo-35444: Fixed error handling in pickling methods when fail to look up \ 
builtin “getattr”.
- bpo-35436: Fix various issues with memory allocation error handling. Patch by \ 
Zackery Spytz.
- bpo-35357: Internal attributes’ names of unittest.mock._Call and \ 
unittest.mock.MagicProxy (name, parent & from_kall) are now prefixed with \ 
_mock_ in order to prevent clashes with widely used object attributes. Fixed \ 
minor typo in test function name.
- bpo-35372: Fixed the code page decoder for input longer than 2 GiB containing \ 
undecodable bytes.
- bpo-35336: Fix PYTHONCOERCECLOCALE=1 environment variable: only coerce the C \ 
locale if the LC_CTYPE locale is “C”.
- bpo-33954: For str.format(), float.__format__() and complex.__format__() \ 
methods for non-ASCII decimal point when using the “n” formatter.
- bpo-35269: Fix a possible segfault involving a newly-created coroutine. Patch \ 
by Zackery Spytz.
- bpo-35214: Fixed an out of bounds memory access when parsing a truncated \ 
unicode escape sequence at the end of a string such as '\N'. It would read one \ 
byte beyond the end of the memory allocation.
- bpo-35214: The interpreter and extension modules have had annotations added so \ 
that they work properly under clang’s Memory Sanitizer. A new configure flag \ 
–with-memory-sanitizer has been added to make test builds of this nature \ 
easier to perform.
- bpo-35193: Fix an off by one error in the bytecode peephole optimizer where it \ 
could read bytes beyond the end of bounds of an array when removing unreachable \ 
code. This bug was present in every release of Python 3.6 and 3.7 until now.
- bpo-29341: Clarify in the docstrings of os methods that path-like objects are \ 
also accepted as input parameters.
- bpo-35050: socket: Fix off-by-one bug in length check for AF_ALG name and type.
- bpo-34974: bytes and bytearray constructors no longer convert unexpected \ 
exceptions (e.g. MemoryError and KeyboardInterrupt) to TypeError.
- bpo-34973: Fixed crash in bytes() when the list argument is mutated while it \ 
is iterated.
- bpo-34824: Fix a possible null pointer dereference in Modules/_ssl.c. Patch by \ 
Zackery Spytz.
- bpo-1621: Do not assume signed integer overflow behavior (C undefined \ 
behavior) when performing set hash table resizing.

- bpo-35052: Fix xml.dom.minidom cloneNode() on a document with an entity: pass \ 
the correct arguments to the user data handler of an entity.
- bpo-35330: When a Mock instance was used to wrap an object, if side_effect is \ 
used in one of the mocks of it methods, don’t call the original implementation \ 
and return the result of using the side effect the same way that it is done with \ 
- bpo-34172: Revert the fix for this issue previously released in 3.7.1 pending \ 
further investigation: Fix a reference issue inside multiprocessing.Pool that \ 
caused the pool to remain alive if it was deleted without being closed or \ 
terminated explicitly.
- bpo-10496: posixpath.expanduser() now returns the input path unchanged if the \ 
HOME environment variable is not set and the current user has no home directory \ 
(if the current user identifier doesn’t exist in the password database). This \ 
change fix the site module if the current user doesn’t exist in the password \ 
database (if the user has no home directory).
- bpo-35310: Fix a bug in select.select() where, in some cases, the file \ 
descriptor sequences were returned unmodified after a signal interruption, even \ 
though the file descriptors might not be ready yet. select.select() will now \ 
always return empty lists if a timeout has occurred. Patch by Oran Avraham.
- bpo-35380: Enable TCP_NODELAY on Windows for proactor asyncio event loop.
- bpo-35341: Add generic version of collections.OrderedDict to the typing \ 
module. Patch by Ismo Toijala.
- bpo-35371: Fixed possible crash in os.utime() on Windows when pass incorrect \ 
- bpo-27903: Fix ResourceWarning in platform.dist() on SuSE and Caldera \ 
OpenLinux. Patch by Ville Skyttä.
- bpo-35308: Fix regression in webbrowser where default browsers may be \ 
preferred over browsers in the BROWSER environment variable.
- bpo-28604: locale.localeconv() now sets temporarily the LC_CTYPE locale to the \ 
LC_MONETARY locale if the two locales are different and monetary strings are \ 
non-ASCII. This temporary change affects other threads.
- bpo-35277: Update ensurepip to install pip 18.1 and setuptools 40.6.2.
- bpo-35226: Recursively check arguments when testing for equality of \ 
unittest.mock.call objects and add note that tracking of parameters used to \ 
create ancestors of mocks in mock_calls is not possible.
- bpo-29564: The warnings module now suggests to enable tracemalloc if the \ 
source is specified, the tracemalloc module is available, but tracemalloc is not \ 
tracing memory allocations.
- bpo-35189: Modify the following fnctl function to retry if interrupted by a \ 
signal (EINTR): flock, lockf, fnctl
- bpo-35062: Fix incorrect parsing of _io.IncrementalNewlineDecoder’s \ 
translate argument.
- bpo-35079: Improve difflib.SequenceManager.get_matching_blocks doc by adding \ 
‘non-overlapping’ and changing ‘!=’ to ‘<’.
- bpo-35017: socketserver.BaseServer.serve_forever() now exits immediately if \ 
it’s shutdown() method is called while it is polling for new events.
- bpo-31047: Fix ntpath.abspath regression where it didn’t remove a trailing \ 
separator on Windows. Patch by Tim Graham.
- bpo-34794: Fixed a leak in Tkinter when pass the Python wrapper around Tcl_Obj \ 
back to Tcl/Tk.
- bpo-35008: Fixed references leaks when call the __setstate__() method of \ 
xml.etree.ElementTree.Element in the C implementation for already initialized \ 
- bpo-23420: Verify the value for the parameter ‘-s’ of the cProfile CLI. \ 
Patch by Robert Kuska
- bpo-33947: dataclasses now handle recursive reprs without raising RecursionError.
- bpo-16965: The 2to3 execfile fixer now opens the file with mode 'rb'. Patch by \ 
Zackery Spytz.
- bpo-34966: pydoc now supports aliases not only to methods defined in the end \ 
class, but also to inherited methods. The docstring is not duplicated for \ 
- bpo-34941: Methods find(), findtext() and findall() of the Element class in \ 
the xml.etree.ElementTree module are now able to find children which are \ 
instances of Element subclasses.
- bpo-34936: Fix TclError in tkinter.Spinbox.selection_element(). Patch by \ 
Juliette Monsel.
- bpo-34866: Adding max_num_fields to cgi.FieldStorage to make DOS attacks \ 
harder by limiting the number of MiniFieldStorage objects created by \ 
- bpo-34022: The SOURCE_DATE_EPOCH environment variable no longer overrides the \ 
value of the invalidation_mode argument to py_compile.compile(), and determines \ 
its default value instead.
- bpo-34738: ZIP files created by distutils will now include entries for directories.
- bpo-31177: Fix bug that prevented using reset_mock on mock instances with \ 
deleted attributes
- bpo-34536: Enum._missing_: raise ValueError if None returned and TypeError if \ 
non-member is returned.
- bpo-34604: Fix possible mojibake in the error message of pwd.getpwnam and \ 
grp.getgrnam using string representation because of invisible characters or \ 
trailing whitespaces. Patch by William Grzybowski.
- bpo-34574: OrderedDict iterators are not exhausted during pickling anymore. \ 
Patch by Sergey Fedoseev.
- bpo-34052: sqlite3.Connection.create_aggregate(), \ 
sqlite3.Connection.create_function(), sqlite3.Connection.set_authorizer(), \ 
sqlite3.Connection.set_progress_handler() methods raises TypeError when \ 
unhashable objects are passed as callable. These methods now don’t pass such \ 
objects to SQLite API. Previous behavior could lead to segfaults. Patch by \ 
Sergey Fedoseev.
- bpo-29877: compileall: import ProcessPoolExecutor only when needed, preventing \ 
hangs on low resource platforms
- bpo-22005: Implemented unpickling instances of datetime, date and time pickled \ 
by Python 2. encoding='latin1' should be used for successful decoding.

python37: add pymalloc option.

pymalloc is on by default in non pkgsrc builds. Add option to allow it in
pkgsrc but don't enable so pkgsrc defaults don't change

Log message:
python37: updated to 3.7.1

Notable changes in Python 3.7.1

Starting in 3.7.1, Py_Initialize() now consistently reads and respects all of \ 
the same environment settings as Py_Main() (in earlier Python versions, it \ 
respected an ill-defined subset of those environment variables, while in Python \ 
3.7.0 it didn’t read any of them due to bpo-34247). If this behavior is \ 
unwanted, set Py_IgnoreEnvironmentFlag to 1 before calling Py_Initialize().

In 3.7.1 the C API for Context Variables was updated to use PyObject pointers.

xml.dom.minidom and xml.sax modules no longer process external entities by default.
