Parallel filesystem cache for compiled bytecode
Debug builds share ABI as release builds
f-strings support a handy = specifier for debugging
continue is now legal in finally: blocks
on Windows, the default asyncio event loop is now ProactorEventLoop
on macOS, the spawn start method is now used by default in multiprocessing
multiprocessing can now use shared memory segments to avoid pickling costs between processes
typed_ast is merged back to CPython
LOAD_GLOBAL is now 40% faster
pickle now uses Protocol 4 by default, improving performance
Add type annotations to your Python programs, and use mypy to type check them.
Mypy is essentially a Python linter on steroids, and it can catch many
programming errors by analyzing your program, without actually having to run
it. Mypy has a powerful type system with features such as type inference,
gradual typing, generics and union types.
This allows users to simply install a "go" package and pull in the latest
version available for their host operating system without having to figure
out the name for the correct suffixed package.
This is necessary for firefox 63.0
This project can be used to generate C bindings for Rust code.
It is currently being developed to support creating bindings for WebRender,
but has been designed to support any project.
Replacements: the versioned lang/go19, lang/go110 and lang/go111.
Nothing in pkgsrc directly depends on this anymore. There are a few
stragglers in wip, which will be fixed.
A native Python cross-version decompiler and fragment decompiler. The successor
to decompyle, uncompyle, and uncompyle2.
uncompyle6 translates Python bytecode back into equivalent Python source code.
It accepts bytecodes from Python version 1.3 to version 3.7, spanning over 22
years of Python releases. We include Dropbox's Python 2.5 bytecode and some
PyPy bytecode.
This uses a similar approach as go111. Its revision is one higher than
the existing lang/go.
Next steps:
- make builds use this for dependent packages
- delete lang/go to complete the move
This installs the go tool as go111; all the supporting files go under
$PREFIX/go111, so it does not conflict with other Go versions. Go packages
in pkgsrc do not use it to build yet.
Changes:
There are many changes and improvements to the toolchain, runtime, and
libraries, but two features stand out as being especially exciting: modules
and WebAssembly support.
This release adds preliminary support for a new concept called "modules," an
alternative to GOPATH with integrated support for versioning and package
distribution. Module support is considered experimental, and there are still
a few rough edges to smooth out, so please make liberal use of the issue
tracker.
Go 1.11 also adds an experimental port to WebAssembly (js/wasm). This allows
programmers to compile Go programs to a binary format compatible with four
major web browsers.
libc++ is a new implementation of the C++ standard library, targeting
C++11.
Features and Goals
* Correctness as defined by the C++11 standard.
* Fast execution.
* Minimal memory use.
* Fast compile times.
* ABI compatibility with gcc's libstdc++ for some low-level features
such as exception objects, rtti and memory allocation.
* Extensive unit tests.
libc++abi is a new implementation of low level support for a standard
C++ library.
Features and Goals
* Correctness as defined by the C++11 standard.
* Provide a portable sublayer to ease the porting of libc++
* On Mac OS X, be ABI compatible with the existing low-level support.
The compiler-rt project consists of:
- builtins - a simple library that provides an implementation of the low-level
target-specific hooks required by code generation and other runtime
components. For example, when compiling for a 32-bit target, converting a
double to a 64-bit unsigned integer is compiling into a runtime call to the
"__fixunsdfdi" function. The builtins library provides optimized
implementations of this and other low-level routines, either in
target-independent C form, or as a heavily-optimized assembly.
- sanitizer runtimes - runtime libraries that are required to run the code
with sanitizer instrumentation. This includes runtimes for:
* AddressSanitizer
* ThreadSanitizer
* UndefinedBehaviorSanitizer
* MemorySanitizer
* LeakSanitizer
* DataFlowSanitizer
- profile - library which is used to collect coverage information.
- BlocksRuntime - a target-independent implementation of Apple "Blocks"
runtime interfaces.
Paver is a Python-based build/distribution/deployment scripting tool along the
lines of Make or Rake. What makes Paver unique is its integration with commonly
used Python libraries. Common tasks that were easy before remain easy. More
importantly, dealing with your applications specific needs and requirements is
also easy.
Python 3.7.0 is the newest major release of the Python language, and it contains many new features and optimizations.
Among the major new features in Python 3.7 are:
PEP 539, new C API for thread-local storage
PEP 545, Python documentation translations
New documentation translations: Japanese, French, and Korean.
PEP 552, Deterministic pyc files
PEP 553, Built-in breakpoint()
PEP 557, Data Classes
PEP 560, Core support for typing module and generic types
PEP 562, Customization of access to module attributes
PEP 563, Postponed evaluation of annotations
PEP 564, Time functions with nanosecond resolution
PEP 565, Improved DeprecationWarning handling
PEP 567, Context Variables
Avoiding the use of ASCII as a default text encoding (PEP 538, legacy C locale coercion and PEP 540, forced UTF-8 runtime mode)
The insertion-order preservation nature of dict objects is now an official part of the Python language spec.
Notable performance improvements in many areas.
py-python-lua is a python3 application which translates python 3 scripts
into Lua. It can act as a standalone translator, or as an embedded package.
Lua can be embedded in Python 3 input scripts, and will be passed through.
