NestedText 3.0
by NestedText July 20, 2021

July 20, 2021

Introducing NestedText 3.0, a nice alternative to JSON, YAML, TOML NestedText is a new file format for holding data that is to be entered, edited, or viewed by people. It allows data to be organized into a nested collection of dictionaries, lists, and strings without the need for quoting or escaping. In this way it is similar to JSON and YAML, but without the complexity and risk of YAML and without the syntactic clutter of JSON. NestedText is both simple and natural. Only a small number of concepts and rules must be kept in mind when creating it. It is easily created, modified, or viewed with a text editor and easily understood and used by both programmers and non-programmers. NestedText is convenient for configuration files, address books, account information and the like. Here is an example of the first entry from a file that contains an address book: # Contact information for our officers president: name: Katheryn McDaniel address: > 138 Almond Street > Topeka, Kansas 20697 phone: cell: 1-210-555-5297 home: 1-210-555-8470 # Katheryn prefers that we always call her on her cell phone. email: KateMcD(a)aol.com additional roles: - board member - new membership task force - accounting task force The format holds dictionaries (ordered collections of name/value pairs), lists (ordered collections of values) and strings (text) organized hierarchically to any depth. Indentation is used to indicate the hierarchy of the data, and a simple natural syntax is used to distinguish the types of data in a simple and intuitive manner. Specifically, lines that begin with a word or words followed by a colon are dictionary items; a dash introduces list items, and a leading greater-than symbol signifies a line in a multiline string. Dictionaries and lists are used for nesting; the leaf values are always strings. However, *NestedText* pairs nicely with *voluptuous* to add data validation and transformation. Currently there is a Python implementation and a language independent test suite. Documentation: https://nestedtext.org Install: pip install nestedtext Support: https://github.com/KenKundert/nestedtext/issues Give it a try. -Ken

pythran 0.9.12 - heskenn
by Serge Guelton July 14, 2021

July 14, 2021

Hi folks, I just shipped a new release of Pythran—a compiler for scientific kernels written in python. It means it is available on PyPI and github, but not yet on conda, fedora, gentoo etc. This one fixes a bunch of issues for Scipy (again), restores compatibility with Cython, but the biggest change is definitively the new dependency tree. Indeed, Pythran no longer depends on networkx, six nor decorator. The dependency on gast and beniget received a version bump for compatibility with python 3.10 changes. Big thanks to the contributors, every commit counts! $ git shortlog -s 0.9.11..0.9.12 1 Ashwin Vishnu 1 Christian Clauss 1 Jochen Schröder 1 Miro Hrončok 2 Ralf Gommers 35 serge-sans-paille 1 刘星雨 A summarized changelog $ git diff 0.9.11..0.9.12 -- Changelog | cut -c 2- (...) 2021-07-06 Serge Guelton <serge.guelton(a)telecom-bretagne.eu> * Remove six, networkx and decorator dependency * Bump gast and Beniget requirements to support python 3.10 * Bump xsimd to 7.5.0 * Minimal default support for non-linux, non-osx, now-windows platform * Numpy improvements for np.bincount, np.transpose, np.searchsorted * Restore (and test) cython compatibility * Expose pythran.get_include for toolchain integration * Improve error message on invalid spec * Handle static dispatching based on keyword signature * Raise Memory Error upon (too) large numpy alloc * Support scalar case of scipy.special.binom * Trim the number of warnings in pythonic codebase (...)

Roundup issue tracker 2.1.0 (20th anniversary edition) released
by John P. Rouillard July 13, 2021

July 13, 2021

Hello Everybody: I'm proud to release version 2.1.0 of the Roundup issue tracker. This 20th anniversary edition has been possible due to the help of several contributors. This release is a bugfix and minor feature release, so make sure to read https://www.roundup-tracker.org/docs/upgrading.html to bring your tracker up to date. 2.1.0 builds on the 2.0.0 major release that introduced: * Python 2 and Python 3 support * a new REST interface * updates to jinja2 templates including security improvements The changes, as usual, include some new features and many bug fixes. Note that you should run ``roundup-admin ... migrate`` to update the database schema version. Do this before you use the web, command-line or mail interface and before any users access the tracker. You can download it with: pip download roundup then unpack and test/install the tarball. Among the notable improvements from the 2.0.0 release are: Mysql backend now uses an index to make sure that key values are not duplicated when two roundup processes run in parallel. (Hence the need for ``roundup-admin ... migrate``.) Postgres back end uses a server side cursor. This reduces the memory use of the roundup process on large queries. Fix sorting of multilinks in templating code. Sorting by a link without a value no longer generates a traceback. Sorting now works as documented by the spec. If ``roundup-admin security`` finds an invalid property, it exits with a non-zero status. It can be used as part of a CI/CD pipeline to validate schema security. Security fixes for jQuery, markdown handling. Fixes to markdown handling if using the jinja2 template. Keyword editing in jinja2 template improved. Fix a number of tracebacks. Installation uses setuptools not distutils. Valid class names are documented and enforced. All class names now match ``[A-z][A-z0-9_]+[A-z_]``. Replace a number of deprecated/missing functions in newer pythons. Fix history showing invalid data when an update is rejected. The filter command in roundup-admin works transitively and handles empty values properly. Password reset documented in user guide. Admins can set the language used for stemming in the xapian indexer. Devel and responsive template strings now extracted for translation. The file CHANGES.txt has a detailed list of feature additions and bug fixes (58) for each release. The most recent changes from there are at the end of this announcement. Also see the information in doc/upgrading.txt. If you find bugs, please report them to issues AT roundup-tracker.org or create an account at https://issues.roundup-tracker.org and open a new ticket. If you have patches to fix the issues they can be attached to the email or uploaded to the tracker. Upgrading ========= If you're upgrading from an older version of Roundup you *must* follow all the "Software Upgrade" guidelines given in the doc/upgrading.txt documentation. Note that you should run ``roundup-admin ... migrate`` to update the database schema version. Do this before you use the web, command-line or mail interface and before any users access the tracker. Roundup requires Python 2 newer than version 2.7.2 or Python 3 newer than or equal to version 3.4 for correct operation. To give Roundup a try, just download (see below), unpack and run:: python demo.py then open the url printed by the demo app. Release info and download page: https://pypi.org/project/roundup Source and documentation is available at the website: https://roundup-tracker.org/ Mailing lists - the place to ask questions: https://sourceforge.net/p/roundup/mailman/ About Roundup ============= Roundup is a simple-to-use and install issue-tracking system with command-line, web and e-mail interfaces. It is based on the winning design from Ka-Ping Yee in the Software Carpentry "Track" design competition. Note: Ping is not responsible for this project. The contact for this project is rouilj at users.sourceforge.net. Use this address for security or other sensitive issues. Development discussions occur on the roundup-devel at lists.sourceforge.net mailing list. Tickets can be opened at https://issues.roundup-tracker.org. Roundup manages a number of issues (with flexible properties such as "description", "priority", and so on) and provides the ability to: (a) submit new issues, (b) find and edit existing issues, and (c) discuss issues with other participants. The system facilitates communication among the participants by managing discussions and notifying interested parties when issues are edited. One of the major design goals for Roundup that it be simple to get going. Roundup is therefore usable "out of the box" with any Python 2.7.2+ (or 3.4+) installation. It doesn't even need to be "installed" to be operational, though an install script is provided. It comes with five basic issue tracker templates * a classic bug/feature tracker * a more extensive devel tracker for bug/features etc. * a responsive version of the devel tracker * a jinja2 version of the devel template (work in progress) * a minimal skeleton and supports four database back-ends (anydbm, sqlite, mysql and postgresql). Recent Changes ============== From 2.0.0 to 2.1.0. Fixed: - Reverse multilink to *the same class* would trigger a traceback about a modified dictionary on iteration (Ralf Schlatterbeck) - issue2551086 - Valid class names not documented. Should follow ``[A-z][A-z0-9_]+[A-z_]``. This was never documented or enforced, but we get obscure errors if the rules are not followed. (Tom Ekberg tests by John Rouilard) - issue2550564 - Roundup sets "Precedence: bulk" on all outgoing mail, which seems wrong. Handle Auto-Submitted header on *inbound* email like we do precedence bulk. This is part of this issue. - roundup-admin filter calls find() not filter when using -s -c -S (John Rouillard) - When requesting transitive properties via ``@fields`` in the REST-API, an empty link in the transitive property (e.g. author.username when requesting message properties) would result in a 404 error. Now we're returning a JSON 'null' value. for an empty link (e.g. empty author in the example). (John Rouillard) - sphinxcontrib.cheeseshop is unmaintained and using old http url. Attempts to override cheeseshop_url failed. Replace call to cheeseshop in docs with raw html and remove references to cheeseshop. (John Rouillard) - issue2551093 - return plain text if markdown formatter throws exception (reported by Cedric Krier, fix by John Rouillard) - issue2551094 - make simplemde handle line breaks the same as the backend markdown formatters. (report: Cedric Krier, patch: Christof Meerwald) - issue2551092 - fix crash bug by aligning ``roundup.anypy.email_.decode_header`` with stdlib ``email.header`` and convert string to bytes for python 3. (Cedric Krier) - issue2551097 - fix underlying bug in use of fenced codeblocks with markdown2. Fix for issue2551093 to prevent exception trigger. (patch: Cedric Krier) - issue2551099 - disable processing of data url's in markdown. Display as plain text. (John Rouillard) - issue2551100 - old jquery has security issues, upgrade it and fix user.help.html (John Rouillard) - replace deprecated base64.decodestring with base64.b64decode in roundup_server.py and roundup_xlmrpc_server.py (reported by lmsteffan in irc) - removed run_tests.py. Newer pytest doesn't support generating stand alone testing bundles. Python 3.9 generates errors running the current run_tests.py. (reported by lmsteffan in irc) - issue2551104 - fix issue with markdown autolink next to punctuation (ced) - removed support for old style trackers that use dbinit.py and config.py. Also remove all uses of deprecated imp module. (John Rouillard) - removed support for setting database type using <database>/backend_name. (John Rouillard) - fixed some issues when generating translations. Use mappings and named format parameters so translators can move substituted tokens in translations. (John Rouillard) - in rest interface, fix uncaught exceptions when parsing invalid Content-Type and Accept headers. Document response formats more fully in doc/rest.txt. (John Rouillard) - in filter, filter_iter and _materialize_multilinks, use named cursor with postgresql. This turns of client-side cursor handling and avoids *large* roundup process (or wsgi process) in case of large results. Fixes issue2551114. (Ralf Schlatterbeck) - issue2551108 - fix handling of designator links when formatted as markdown links. (Reported by Cedric Krier; John Rouillard) - Fix filename created from mail attachments, fixes issue2551118 - Call verifyPassword even if user does not exist.

PyConZA 2021 - Second call for submissions
by Neil Muller July 12, 2021

July 12, 2021

This is a second call for talk proposals for PyConZA 2021. While we've already received several great talk proposals, we still have a number of open talk slots and are thus keen to see further talk submissions. PyCon ZA 2021 will take place on the 7th & 8th of October, 2021. This year, due to the ongoing pandemic, PyCon ZA will again be an online event. We will be streaming the talks and using discord for discussion around the talks and other conference activities. We are looking for the following presentations: - Keynotes (45 minute long talks on a subject of general interest) - Talks (30 minute long talks on more specific topics) If you would like to give a presentation, please register at https://za.pycon.org/ and submit your proposal, following the instructions at https://za.pycon.org/talks/submit-talk/ . We have a number of tracks available, including: Data Science, Teaching and Learning with Python, Web, Scientific Computing, Testing and Other (which includes all talks that don't fall under the mentioned tracks). We hope to notify accepted presenters by no later than the 31st of August 2021. Speakers will be expected to be available after the presentation for a short Q&A session. Shared sessions are also possible. The presentations will be in English. PyCon ZA offers a mentorship program for inexperienced speakers. If you would like assistance preparing your submission, email team(a)za.pycon.org with a rough description of what you would like to talk about and we'll find a suitable experienced speaker to act as a mentor. If you want to present something that doesn't fit into the two talk categories at PyCon ZA, please contact the organising committee at team(a)za.pycon.org so we can discuss whether that will be feasible. -- Neil Muller On behalf of the PyConZA organising committee

[RELEASE] Python 3.10.0b4 is available
by Pablo Galindo Salgado July 11, 2021

July 11, 2021

Wow! A release on a Saturday? Do the release management team even rest? You better believe it, because this is the last of the planned beta releases. This means that the next pre-release will be the first release candidate of Python 3.10.0. Remember that our goal is to have no ABI changes after this beta and a few code changes as possible after 3.10.0rc1. https://www.python.org/downloads/release/python-3100b4/ #This is a beta preview of Python 3.10 Python 3.10 is still in development. 3.10.0b4 is the fourth and last of the 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. We strongly encourage maintainers of third-party Python projects to test with 3.10 during the beta phase and report issues found to the Python bug tracker 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 (Monday, 2021-08-02). Our goal is to have no ABI changes after beta 4 and as few code changes as possible after 3.10.0rc1, the first release candidate. To achieve that, it will be extremely important to get as much exposure for 3.10 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. The next pre-release, the first release candidate of Python 3.10.0, will be 3.10.0rc1. It is currently scheduled for Monday, 2021-08-02. #And now for something completely different In quantum physics, the spin is an intrinsic form of angular momentum carried by elementary particles, composite particles, and atomic nuclei. The spin is one of two types of angular momentum in quantum mechanics, the other being orbital angular momentum. The orbital angular momentum operator is the quantum-mechanical counterpart to the classical angular momentum of orbital revolution and appears when there is periodic structure to its wavefunction as the angle varies. For photons, spin is the quantum-mechanical counterpart of the polarization of light; for electrons, the spin has no classical counterpart. # We hope you enjoy those new releases! Thanks to all of the many volunteers who help make Python Development and these releases possible! Please consider supporting our efforts by volunteering yourself or through organization contributions to the Python Software Foundation. Regards from very cloudy London, Your friendly release team, Pablo Galindo @pablogsal Ned Deily @nad Steve Dower @steve.dower

NetworkX 2.6.1 released
by Jarrod Millman July 9, 2021

July 9, 2021

I am happy to announce NetworkX 2.6.1 (2.6.0 had a minor issue)! This release has a larger than normal number of changes in preparation for the upcoming 3.0 release. The current plan is to release 2.7 near the end of summer and 3.0 in late 2021. The focus of the 3.0 release is on addressing years of technical debt and making it easier to contribute. The 2.6 release deprecates over 30 functions. It also makes major changes to our default dependencies. We no longer depend on the "decorator" library. More importantly, NumPy, SciPy, Matplotlib, and Pandas are now default requirements. While we've made these core libraries of the scientific Python ecosystem default dependencies, much of NetworkX still works without these libraries and we expect that to continue. Be assured that we test NetworkX with and without the dependencies, so if you do **not** use functions that depend on external libraries you can install NetworkX using pip with the `--no-deps` flag. This release supports Python 3.7-3.9 and contains many new features. It is the result of almost a year of work with over 363 pull requests by 91 contributors. If you have code that imports NetworkX, please take some time to check that you are able to update your code to work with the new release. The 2.6 release announcement is here: https://networkx.org/documentation/stable/release/release_2.6.html For more information, please visit our website - http://networkx.org and our gallery of examples - https://networkx.org/documentation/latest/auto_examples/index.html Best regards, Jarrod

[ANN] Austin -- CPython frame stack sampler v3.0.0 is now available
by Gabriele Tornetta July 3, 2021

July 3, 2021

I am delighted to announce the release 3.0.0 of Austin. If you haven't heard of Austin before, it is an open-source frame stack sampler for CPython, distributed under the GPLv3 license. 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 straight away, even while it's running in a production environment, with minimal impact on performance. The best way to leverage Austin is to use the new extension for VS Code, which brings interactive flame graphs straight into the text editor to allow you to quickly jump to the source code with a simple click. You can find the extension on the Visual Studio Marketplace and install it directly from VS Code: https://marketplace.visualstudio.com/items?itemName=p403n1x87.austin-vscode To see how to make the best of Austin with VS Code to find and fix performance issues, check out this blog post, which shows you the editor extension in action on a real Python project: https://p403n1x87.github.io/how-to-bust-python-performance-issues.html The latest release comes with many improvements, including a re-worked sleepless mode that now gives an estimate of CPU time, initial support for Python 3.10, better support for Python-based binaries like gunicorn, uWSGI, etc. on all supported platforms. Austin is a pure C application that has no 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. Austin can be installed easily on the following platforms and from the following sources: Linux: - Snap Store - Debian repositories macOS: - Homebrew Windows: - Chocolatey - Scoop An Austin image, based on Ubuntu 20.04, is also available from Docker Hub: https://hub.docker.com/r/p403n1x87/austin Austin is also simple to compile from sources as it only depends on the standard C library, if you don't have access to the above-listed sources. You can stay up-to-date with the project's development by following Austin on Twitter (https://twitter.com/AustinSampler). All the best, Gabriele <phoenix1987(a)gmail.com> <p><a href="https://github.com/P403n1x87/austin">Austin 3.0.0</a> - frame stack sampler for CPython. (02-Jul-21)</p>
