./lang/python35, Interpreted, interactive, object-oriented programming language

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

Branch: CURRENT, Version: 3.5.3, Package name: python35-3.5.3, 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 3.5.x.

- Issue #25825: Correct the references to Modules/python.exp and ld_so_aix,
  which are required on AIX.  This updates references to an installation path
  that was changed in 3.2a4, and undoes changed references to the build tree
  that were made in 3.5.0a1.

- Issue #27453: CPP invocation in configure must use CPPFLAGS. Patch by
  Chi Hsuan Yen.

- Issue #27641: The configure script now inserts comments into the makefile
  to prevent the pgen and _freeze_importlib executables from being cross-

- Issue #26662: Set PYTHON_FOR_GEN in configure as the Python program to be
  used for file generation during the build.

- Issue #10910: Avoid C++ compilation errors on FreeBSD and OS X.
  Also update FreedBSD version checks for the original ctype UTF-8 workaround.

- Issue #28676: Prevent missing 'getentropy' declaration warning on macOS.

Log message:
Forward port patches from python27 for dlopen(3)

Original changes in python27/Makefile r1.62-r1.67

Add an option for Python: x11

Fix dlopen(3) calls in _ctypes.so for X11BASE libraries

A Python code can dynamically load shared libraries and it's wrapped with
a plain dlopen(3) call. The holder of this interface (_ctypes module)
without rpath set to X11BASE cannot detect libs like 'GL'.

Fixing find_library() on POSIX-like (excluding Darwin) systems.

This isn't addressing Python's wrapper for dlopen(3).

This possibily addresses mostly NetBSD as other popular OSes have ldconfig.

Testing commands:

 - before applying the patch

>>> from ctypes.util import find_library
>>> find_library("m")
>>> find_library("crypto")
>>> find_library("GL")
>>> find_library("curl")

 - after applying the patch
>>> from ctypes.util import find_library
>>> find_library("m")
>>> find_library("crypto")
>>> find_library("GL")
>>> find_library("curl")

This patch doesn't solve the case of custom dirs like $PREFIX/qt5/lib.
However it's solving most common cases of using this call.

A possible solution is to parse the output "pkg_info -La"... however it's
very slow. In other words a cache with libraries might be needed to handle
it efficiently.

Log message:
Changes 3.5.2:
Issue 27066: Fixed SystemError if a custom opener (for open()) returns a \ 
negative number without setting an exception.
Issue 20041: Fixed TypeError when frame.f_trace is set to None. Patch by Xavier \ 
de Gaye.
Issue 26168: Fixed possible refleaks in failing Py_BuildValue() with the “N” \ 
format unit.
Issue 26991: Fix possible refleak when creating a function with annotations.
Issue 27039: Fixed bytearray.remove() for values greater than 127. Patch by Joe \ 
Issue 23640: int.from_bytes() no longer bypasses constructors for subclasses.
Issue 26811: gc.get_objects() no longer contains a broken tuple with NULL pointer.
Issue 20120: Use RawConfigParser for .pypirc parsing, removing support for \ 
interpolation unintentionally added with move to Python 3. Behavior no longer \ 
does any interpolation in .pypirc files, matching behavior in Python 2.7 and \ 
Setuptools 19.0.
Issue 26659: Make the builtin slice type support cycle collection.
Issue 26718: super.__init__ no longer leaks memory if called multiple times. \ 
NOTE: A direct call of super.__init__ is not endorsed!
Issue 25339: PYTHONIOENCODING now has priority over locale in setting the error \ 
handler for stdin and stdout.
Issue 26494: Fixed crash on iterating exhausting iterators. Affected classes are \ 
generic sequence iterators, iterators of str, bytes, bytearray, list, tuple, \ 
set, frozenset, dict, OrderedDict, corresponding views and os.scandir() \ 
Issue 26581: If coding cookie is specified multiple times on a line in Python \ 
source code file, only the first one is taken to account.
Issue 26464: Fix str.translate() when string is ASCII and first replacements \ 
removes character, but next replacement uses a non-ASCII character or a string \ 
longer than 1 character. Regression introduced in Python 3.5.0.
Issue 22836: Ensure exception reports from PyErr_Display() and \ 
PyErr_WriteUnraisable() are sensible even when formatting them produces \ 
secondary errors. This affects the reports produced by sys.__excepthook__() and \ 
when __del__() raises an exception.
Issue 26302: Correct behavior to reject comma as a legal character for cookie names.
Issue 4806: Avoid masking the original TypeError exception when using star (*) \ 
unpacking in function calls. Based on patch by Hagen Fürstenau and Daniel \ 
Issue 27138: Fix the doc comment for FileFinder.find_spec().
Issue 26154: Add a new private _PyThreadState_UncheckedGet() function to get the \ 
current Python thread state, but don’t issue a fatal error if it is NULL. This \ 
new function must be used instead of accessing directly the \ 
_PyThreadState_Current variable. The variable is no more exposed since Python \ 
3.5.1 to hide the exact implementation of atomic C types, to avoid compiler \ 
Issue 26194: Deque.insert() gave odd results for bounded deques that had reached \ 
their maximum size. Now an IndexError will be raised when attempting to insert \ 
into a full deque.
Issue 25843: When compiling code, don’t merge constants if they are equal but \ 
have a different types. For example, f1, f2 = lambda: 1, lambda: 1.0 is now \ 
correctly compiled to two different functions: f1() returns 1 (int) and f2() \ 
returns 1.0 (int), even if 1 and 1.0 are equal.
Issue 22995: [UPDATE] Comment out the one of the pickleability tests in \ 
_PyObject_GetState() due to regressions observed in Cython-based projects.
Issue 25961: Disallowed null characters in the type name.
Issue 25973: Fix segfault when an invalid nonlocal statement binds a name \ 
starting with two underscores.
Issue 22995: Instances of extension types with a state that aren’t subclasses \ 
of list or dict and haven’t implemented any pickle-related methods \ 
(__reduce__, __reduce_ex__, __getnewargs__, __getnewargs_ex__, or __getstate__), \ 
can no longer be pickled. Including memoryview.
Issue 20440: Massive replacing unsafe attribute setting code with special macro \ 
Issue 25766: Special method __bytes__() now works in str subclasses.
Issue 25421: __sizeof__ methods of builtin types now use dynamic basic size. \ 
This allows sys.getsize() to work correctly with their subclasses with __slots__ \ 
Issue 25709: Fixed problem with in-place string concatenation and utf-8 cache.
Issue 27147: Mention PEP 420 in the importlib docs.
Issue 24097: Fixed crash in object.__reduce__() if slot name is freed inside \ 
Issue 24731: Fixed crash on converting objects with special methods __bytes__, \ 
__trunc__, and __float__ returning instances of subclasses of bytes, int, and \ 
float to subclasses of bytes, int, and float correspondingly.
Issue 26478: Fix semantic bugs when using binary operators with dictionary views \ 
and tuples.
Issue 26171: Fix possible integer overflow and heap corruption in \ 
Issue 25660: Fix TAB key behaviour in REPL with readline.
Issue 25887: Raise a RuntimeError when a coroutine object is awaited more than once.
Issue 27243: Update the __aiter__ protocol: instead of returning an awaitable \ 
that resolves to an asynchronous iterator, the asynchronous iterator should be \ 
returned directly. Doing the former will trigger a PendingDeprecationWarning.
