[baseline 0.2.1] Easy String Baseline
by Dan Gass 29 Mar '20

29 Mar '20

I am please to announce the availability of the "baseline" package. This tool streamlines creation and maintenance of tests which compare string output against a baseline. It offers a mechanism to compare a string against a baselined copy and update the baselined copy to match the new value when a mismatch occurs. The update process includes a manual step to facilitate a review of the change before acceptance. The tool uses multi-line string format for string baselines to improve readability for human review. Docs: https://baseline.readthedocs.io/en/latest/ PyPi: https://pypi.org/project/baseline/ Repo: https://github.com/dmgass/baseline License: MIT With Regards, Dan Gass (dan.gass at gmail) *********** Quick Start *********** Create an empty baseline with a triple quoted multi-line string. Place the ending triple quote on a separate line and indent it to the level you wish the string baseline update to be indented to. Add a compare of the string being tested to the baseline string. Then save the file as ``fox.py``: .. code-block:: python from baseline import Baseline expected = Baseline(""" """) test_string = "THE QUICK BROWN FOX\n JUMPS\nOVER THE LAZY DOG." assert test_string == expected Run ``fox.py`` and observe that the ``assert`` raises an exception since the strings are not equal. Because the comparison failed, the tool located the triple quoted baseline string in the source file and updated it with the miscompared value. When the interpretter exited, the tool saved the updated source file but changed the file name to ``fox.update.py``: .. code-block:: python from baseline import Baseline expected = Baseline(""" THE QUICK BROWN FOX JUMPS OVER THE LAZY DOG. """) test_string = "THE QUICK BROWN FOX\n JUMPS\nOVER THE LAZY DOG." assert test_string == expected After reviewing the change with your favorite file differencing tool, accept the change by either manually overwriting the original file or use the ``baseline`` command line tool to scan the directory for updated scripts and accept them: .. code-block:: shell $ python -m baseline * Found updates for: fox.py Hit [ENTER] to update, [Ctrl-C] to cancel fox.update.py -> fox.py Run ``fox.py`` again and observe the ``assert`` does not raise an exception nor is a source file update generated. If in the future the test value changes, the ``assert`` will raise an exception and cause a new source file update to be generated. Simply repeat the review and acceptance step and you are back in business! <P><A HREF="https://baseline.readthedocs.io/en/latest/"> baseline 0.2.1</A> - Easy String Baseline (07-Jun-18)

Austin -- CPython frame stack sampler 0.7.0
by Gabriele 30 Jul '19

30 Jul '19

I am delighted to announce the release 0.7.0 of Austin. If you haven't heard of Austin before, it is a frame stack sampler for CPython. It can be used to obtain statistical profiling data out of a running Python application without a single line of instrumentation. This means that you can start profiling a Python application straightaway, even while it's running on a production environment, with minimal impact on performance. The simplest way of using Austin is by piping its output to FlameGraph for a quick and detailed representation of the collected samples. The latest release introduces a memory profiling mode which allows you to profile memory usage. Austin is a pure C application that has no other dependencies other than the C standard library. Its source code is hosted on GitHub at https://github.com/P403n1x87/austin The README contains installation and usage details, as well as some examples of Austin in action. Details on how to contribute to Austin's development can be found at the bottom of the page. I hope that you can find Austin useful! All the best, Gabriele

[RELEASE] Python 3.8.0b3 is now available for testing
by Łukasz Langa 29 Jul '19

29 Jul '19

This time without delays, I present you Python 3.8.0b3: https://www.python.org/downloads/release/python-380b3/ <https://www.python.org/downloads/release/python-380b3/> This release is the third of four planned beta release previews. Beta release previews are intended to give the wider community the opportunity to test new features and bug fixes and to prepare their projects to support the new feature release. The next pre-release of Python 3.8 will be 3.8.0b4, the last beta release, currently scheduled for 2019-08-26. Call to action We strongly encourage maintainers of third-party Python projects to test with 3.8 during the beta phase and report issues found to the Python bug tracker <https://bugs.python.org/> as soon as possible. While the release is planned to be feature complete entering the beta phase, it is possible that features may be modified or, in rare cases, deleted up until the start of the release candidate phase (2019-09-30). Our goal is have no ABI changes after beta 3 and no code changes after 3.8.0rc1, the release candidate. To achieve that, it will be extremely important to get as much exposure for 3.8 as possible during the beta phase. Please keep in mind that this is a preview release and its use is not recommended for production environments. Last beta coming Beta 4 can only be released if all “Release blocker” and “Deferred blocker” issues on bugs.python.org <http://bugs.python.org/> for 3.8.0 are resolved. Please prioritize those for the next four weeks. Acknowledgements Thanks to our binary builders, Ned and Steve, who were very quick today to get the macOS and Windows installers ready. The Windows story in particular got pretty magical, it’s now really fully automatic end-to-end. Thanks to Victor for vastly improving the reliability of multiprocessing tests since Beta 2. Thanks to Pablo for keeping the buildbots green. - Ł

NumPy 1.17.0 released
by Charles R Harris 26 Jul '19

26 Jul '19

Hi All, On behalf of the NumPy team I am pleased to announce the release of NumPy 1.17.0. The 1.17.0 release contains a number of new features that should substantially improve its performance and usefulness. The Python versions supported are 3.5-3.7, note that Python 2.7 has been dropped. Python 3.8b2 should work with the released source packages, but there are no guarantees about future releases. Highlights of this release are: - A new extensible random module along with four selectable random number generators and improved seeding designed for use in parallel processes has been added. The currently available bit generators are MT19937, PCG64, Philox, and SFC64. - NumPy's FFT implementation was changed from fftpack to pocketfft, resulting in faster, more accurate transforms and better handling of datasets of prime length. - New radix sort and timsort sorting methods. It is currently not possible to choose which will be used, but they are hardwired to the datatype and used when either ``stable`` or ``mergesort`` is passed as the method. - Overriding numpy functions is now possible by default Downstream developers should use Cython >= 0.29.10 for Python 3.8 support and OpenBLAS >= 3.7 (not currently out) to avoid problems on the Skylake architecture. The NumPy wheels on PyPI are built from the OpenBLAS development branch in order to avoid those problems. Wheels for this release can be downloaded from PyPI <https://pypi.org/project/numpy/1.17.0/>, source archives and release notes are available from Github <https://github.com/numpy/numpy/releases/tag/v1.17.0>. *Contributors* A total of 150 people contributed to this release.

Aioli: Non-blocking Web API framework
by Robert Wikman 21 Jul '19

21 Jul '19

Hello, Thought I'd announce a project I've been working on for some time. Aioli is a Framework for building RESTful HTTP and WebSocket APIs with asyncio. Its easy-to-use component system--built with an emphasis on portability and composability--offers a sensible separation of application logic, data access, and request/response layers. Some links. Framework Github repo: https://github.com/aioli-framework/aioli Documentation: https://docs.aioli.dev Extensions: https://github.com/aioli-framework/aioli-rdbms -- Mysql and Postgres support https://github.com/aioli-framework/aioli-openapi -- Generate OAS3 schemas using Aioli Route Handlers Fully functional (and quite comprehensive) RESTful HTTP API example: https://github.com/aioli-framework/aioli-guestbook-example Note that the project is still under development and lacks some features, documentation, and tests. Let me know if you have any questions, suggestions or such. -- Robert Wikman 0xf6feb506ae5d3762
