...API that is close to the original API—to make porting easy—and have it perform as close to the existing API as possible. At the same time, HPy is sufficently removed to be a good "C extension API" (as opposed to a stable subset of the CPython implementation API) that does not leak implementation details. To ensure this latter property, the HPy project tries to develop everything in parallel for CPython, PyPy, and GraalVM Python. HPy is still evolving very fast. Issues are still being solved whil...
...API additions through some kind of a preview mechanism for a full release, we get one full release cycle of community feedback before we lock in the APIs with our standard backward compatibility guarantee. We can also start integrating preview modules with the rest of the standard library early, so long as we make it clear to packagers that the preview modules should not be considered optional. The only difference between preview APIs and the rest of the standard library is that preview APIs ar...
...api/init.rst will be updated with the added API. Impact Backwards Compatibility No behavior or APIs are intended to change due to this proposal, with one exception noted in the next section. The existing C-API for managing interpreters will preserve its current behavior, with new behavior exposed through new API. No other API or runtime behavior is meant to change, including compatibility with the stable ABI. See Objects Exposed in the C-API below for related discussion. Extension Modules ...
...API failing when the other API would have worked. Specification On Windows, Python uses the wide character APIs to access character-oriented APIs, allowing direct conversion of the environmental data to Python str objects (PEP 277). On POSIX systems, Python currently applies the locale's encoding to convert the byte data to Unicode, failing for characters that cannot be decoded. With this PEP, non-decodable bytes >= 128 will be represented as lone surrogate codes U+DC80..U+DCFF. Bytes below...
...API New C API functions Python API Open issues Backwards Compatibility Reference Implementation Acknowledgments Copyright References Withdrawal Notice This PEP has been withdrawn by its author, as much of the detailed design is no longer valid following the migration to importlib in Python 3.3. Abstract This PEP proposes enhancements for the import machinery to add post import hooks. It is intended primarily to support the wider use of abstract base classes that is expected in Python 3....
...API Constructors Comparisons Slicing Indexing Str() and Repr() Operators Methods Bytes and the Str Type The basestring Type Pickling Copyright Introduction After releasing Python 3.0a1 with a mutable bytes type, pressure mounted to add a way to represent immutable bytes. Gregory P. Smith proposed a patch that would allow making a bytes object temporarily immutable by requesting that the data be locked using the new buffer API from PEP 3118. This did not seem the right approach to me. Jeff...
...API and specific behaviors for the CPython implementation that make actions taken by the Python runtime visible to auditing tools. Visibility into these actions provides opportunities for test frameworks, logging frameworks, and security tools to monitor and optionally limit actions taken by the runtime. This PEP proposes adding two APIs to provide insights into a running Python application: one for arbitrary events, and another specific to the module import system. The APIs are intended to be a...
...API. However, the new secrets module introduced by PEP 506 will be updated to catch the new exception and implicitly wait for the system random number generator if the exception is ever encountered. In all cases, as soon as a call to one of these security sensitive APIs succeeds, all future calls to these APIs in that process will succeed without blocking (once the operating system random number generator is ready after system boot, it remains ready). On Linux and NetBSD, this will replace the p...

...APIs and features are available prior to pre-configuration (essentially none, except for the pre-configuration API itself) which APIs and features are available prior to core runtime configuration, and will implicitly run the pre-configuration with default settings that match the behaviour of Python 3.6 if the pre-configuration hasn't been run explicitly which APIs and features are only available after the main interpreter has been fully configured (which will hopefully be a relatively small sub...
...API looks like is the implementation that powers PyPI. This document will specify that API, documenting what the correct behavior for any implementation of the simple repository API. Specification A repository that implements the simple API is defined by its base URL, this is the top level URL that all additional URLs are below. The API is named the "simple" repository due to the fact that PyPI's base URL is https://pypi.org/simple/. Note All subsequent URLs in this document will be relative ...
...API project is to develop a package- independent API for plots, which would produce reasonably similar results regardless of the plotting package used as a backend (PLPlot, Gist/Yorick, Gnuplot, etc.), in the same spirit as the interface defined by the DB-SIG. Package-specific extensions could naturally be provided as well. The goals for the new framework need to be further specified by the SIG, but include: Complete Python Control. Extensibility/Customiza...
...API will change. Issue 3042 in the tracker proposes that for Python 2.6 there will be two APIs for the threading module - the current one, and the PEP 8 compliant one. Warnings about the upcoming removal of the original java-style API will be issued when -3 is invoked. In Python 3000, the threading API will become PEP 8 compliant, which means that the multiprocessing module and the threading module will again have matching APIs. Timing/Schedule Some concerns have been raised about the timing/l...
...API, etc.). PEPs related to this effort are: PEP 384 -- Defining a Stable ABI, which added C API for creating heap types PEP 489 -- Multi-phase extension module initialization PEP 573 -- Module State Access from C Extension Methods This document is concerned with Python's public C API, which is not offered by all implementations of Python. However, nothing in this PEP is specific to CPython. As with any Informational PEP, this text does not necessarily represent a Python community consensus o...
...APIs, and introduced wchar_t *wstr, and Py_ssize_t wstr_length in the Unicode structure to support these deprecated APIs. This PEP is planning removal of wstr, and wstr_length with deprecated APIs using these members by Python 3.12. Deprecated APIs which doesn't use the members are out of scope because they can be removed independently. Motivation Memory usage str is one of the most used types in Python. Even most simple ASCII strings have a wstr member. It consumes 8 bytes per string on 64-b...
...APIs are available that provide direct access to all file names, including those that are not representable using the current locale. The purpose of this proposal is to provide access to these wide-character APIs through the standard Python file object and posix module and so provide access to all files on Windows NT. Specification On Windows platforms which provide wide-character file APIs, when Unicode arguments are provided to file APIs, wide-character calls are made instead of the standar...
...API that was platform independent, easy to use, had all the strengths of a modern programming language, and was extendable and embeddable. Choosing Python Tribon began work on its API in 1995. Two different paths were considered at this stage: Either to publish directly the libraries used by Tribon, or to create a wrapper on top of existing code. The first approach would make all our functionality available to the user, but users would have to use the same development environment as Tribon Sol...
