as an unresolved undefined symbol, causing the install to fail due to
PLIST issues. Change from -std=c99 to -std=gnu99 to work around this
problem, based on hint from joerg@.
Bump PKGREVISION.
Major new features of the 3.6 series, compared to 3.5
Among the new major new features in Python 3.6 are:
PEP 468, Preserving Keyword Argument Order
PEP 487, Simpler customization of class creation
PEP 495, Local Time Disambiguation
PEP 498, Literal String Formatting
PEP 506, Adding A Secrets Module To The Standard Library
PEP 509, Add a private version to dict
PEP 515, Underscores in Numeric Literals
PEP 519, Adding a file system path protocol
PEP 520, Preserving Class Attribute Definition Order
PEP 523, Adding a frame evaluation API to CPython
PEP 524, Make os.urandom() blocking on Linux (during system startup)
PEP 525, Asynchronous Generators (provisional)
PEP 526, Syntax for Variable Annotations (provisional)
PEP 528, Change Windows console encoding to UTF-8
PEP 529, Change Windows filesystem encoding to UTF-8
PEP 530, Asynchronous Comprehensions
According to Python 3.6 changelog:
The undocumented IN, CDROM, DLFCN, TYPES, CDIO, and STROPTS modules have been
removed. They had been available in the platform specific Lib/plat-*/
directories, but were chronically out of date, inconsistently available across
platforms, and unmaintained. The script that created these modules is still
available in the source distribution at Tools/scripts/h2py.py.
No PKGREVISION bump since they failed to install on these platforms.
TODO: PLIST.IRIX entries seems to still contains plat-* modules but the ones
TODO: contained are not explicitly documented in the changelog, so they can
TODO: maybe still installed.
Pointed out by Joyent's Linux and SmartOS bulk builds and thanks to <jperkin>
for testing it!
Summary – Release highlights
New syntax features:
PEP 498, formatted string literals.
PEP 515, underscores in numeric literals.
PEP 526, syntax for variable annotations.
PEP 525, asynchronous generators.
PEP 530: asynchronous comprehensions.
New library modules:
secrets: PEP 506 – Adding A Secrets Module To The Standard Library.
CPython implementation improvements:
The dict type has been reimplemented to use a more compact representation based on a proposal by Raymond Hettinger and similar to the PyPy dict implementation. This resulted in dictionaries using 20% to 25% less memory when compared to Python 3.5.
Customization of class creation has been simplified with the new protocol.
The class attribute definition order is now preserved.
The order of elements in **kwargs now corresponds to the order in which keyword arguments were passed to the function.
DTrace and SystemTap probing support has been added.
The new PYTHONMALLOC environment variable can now be used to debug the interpreter memory allocation and access errors.
Significant improvements in the standard library:
The asyncio module has received new features, significant usability and performance improvements, and a fair amount of bug fixes. Starting with Python 3.6 the asyncio module is no longer provisional and its API is considered stable.
A new file system path protocol has been implemented to support path-like objects. All standard library functions operating on paths have been updated to work with the new protocol.
The datetime module has gained support for Local Time Disambiguation.
The typing module received a number of improvements and is no longer provisional.
The tracemalloc module has been significantly reworked and is now used to provide better output for ResourceWarning as well as provide better diagnostics for memory allocation errors. See the PYTHONMALLOC section for more information.
Security improvements:
The new secrets module has been added to simplify the generation of cryptographically strong pseudo-random numbers suitable for managing secrets such as account authentication, tokens, and similar.
On Linux, os.urandom() now blocks until the system urandom entropy pool is initialized to increase the security. See the PEP 524 for the rationale.
The hashlib and ssl modules now support OpenSSL 1.1.0.
The default settings and feature set of the ssl module have been improved.
The hashlib module received support for the BLAKE2, SHA-3 and SHAKE hash algorithms and the scrypt() key derivation function.
