Roundup issue tracker 2.0.0 released (supports python 3)
by John P. Rouillard 13 Jul '20

13 Jul '20

Hello: I'm proud to release version 2.0.0 of the Roundup issue tracker which has been possible due to the help of several contributors. This release contains some major changes, so make sure to read `docs/upgrading.txt <http://www.roundup-tracker.org/docs/upgrading.html>`_ to bring your tracker up to date. There are special directions for those using mysql backend. The changes, as usual, include some new features and many bug fixes. You can download it with: pip download roundup then unpack and test/install the tarball. Among the notable improvements from the 1.6.1 release are: Roundup is multilingual and will run under either Python 3 or Python 2. If you want to use Python 3, you *must read* the Python 3 Support section in the upgrading doc. Depending on the database backend you may have to export/import the tracker. Also you will need to make sure your tracker's Python code is Python 3 compliant. Thanks to Joseph Myers with help from Christof Meerwald. Roundup has a rest API to go along with the existing xmlrpc API. See doc/rest.txt for details on configuring, authorizing access (per role) and making a request. Thanks to Ralf Schlatterbeck who integrated and updated Chau Nguyen's GSOC code. PGP encryption is now done using the gpg module and not the obsolete pyme library. Thanks to Christof Meerwald. Use of mod_python is deprecated. Apache mod_wsgi documentation has been updated along with gunicorn and uwsgi and is the preferred mechanism. jinja templates updated to bootstrap 4.4.1. Templates use autoescape and translation library. Support for messages written in markdown added. SimpleMDE used as markdown editor to provide preview features. Thanks to Christof Meerwald. Fixes to mysql indexing may require a database dump/restore. The file CHANGES.txt has a detailed list of feature additions and bug fixes 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. Roundup requires Python 2 newer than version 2.7.2 or Python 3 newer than or equal to version 3.4 for correct operation. The wsgi, server and cgi web deployment modes are the ones with the most testing. To give Roundup a try, just download (see below), unpack and run:: python demo.py Release info and download page: https://pypi.org/project/roundup Source and documentation is available at the website: http://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 richard(a)users.sourceforge.net. 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 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 (since 2.0.0beta) ================================ Features: - Allow to pass additional headers to nosymessage, nice if a message needs to be marked as urgent or similar, e.g., Outlook uses an "Importance" header, when set to "high" it highlights the message. (Ralf Schlatterbeck) - issue2550926 - Original author adding a second message shouldn't set status to 'chatting'. See upgrading.txt for details. (John Rouillard) - issue2550919 - Anti-bot signup using 4 second delay. New config.ini param [web] registration_delay must be set to 0 if template user.register.html is not modified. See upgrading.txt for details. - Reimplement -u <login>[:<password>]. This opens the database as the user and applies expected permissions. It also creates history entries for the user. Note that the password is unused, no mention of it is in the spec that I can find, so not sure what it was supposed to be used for as the CLI has full access to the files so a password check is not useful. An edge case is when the login has a : in it. In this case it may not work as expected. So don't do that. - Implement Cache-Control headers for static files. Allows tracker admin to control caching for css, js and other static files. See customizing.html. The use is documented in the section describing how to use interfaces.py. - issue2551071 Update jinja template to bootstrap 4. Updated to 4.4.1. The pull request has been around for a while. (Patch: Paul Spooren; templates merged and additional changes by Christof Meerwald; other merged by John Rouillard) - Add config option 'http_auth_convert_realm_to_lowercase' If usernames consist of a name and a domain/realm part of the form user@realm and we're using REMOTE_USER for authentication (e.g. via Kerberos), convert the realm part of the incoming REMOTE_USER to lowercase before matching against the roundup username. This allows roundup usernames to be lowercase (including the realm) and still follow the Kerberos convention of using an uppercase realm. In addition this is compatible with Active Directory which stores the username with realm as UserPrincipalName in lowercase. - Cleaned up the WSGI interface implementation by separating the request handler from the request displatcher. Also allow customisation of tracker instance creation via an overridable "get_tracker" context manager. - Allow transitive properties in @fields in REST API. These transitive properties may not cross Multilinks, e.g., when querying 'issue' the property 'messages.author' is not allowed (because 'messages' is a multilink). A multilink at the end (e.g. messages in the example) is fine. - Added markdown rendering using markdown, markdown2 or mistune; use SimpleMDE markdown editor in jinja2 template (Christof Meerwald) - Allow filtering by multiple date ranges or empty date. Date ranges are separated by comma, an empty date is represented by '-' - issue2551083 - Replace BaseException and Exception as base classes with new RoundupException (inheriting from Exception) for most roundup exceptions. (John Rouillard and Ralf Schlatterbeck on request from Robert Klonner.) Fixed: - issue2550996 - Give better error message when running with -c (install as windows service) and pywin32 is not importable. Could use better testing on a windows box. (John Rouillard) - issue2550921 - Can create login name with , in it. Confuses nosy list editing. Also can embed html tags. Updated userauditor.py to prevent this. See updating.txt. (John Rouillard) - issue1344046 - Search for "All text" can't find some Unicode words (John Rouillard, Ezio Melotti) - issue1195739 - search in russian does not work (John Rouillard, Ezio Melotti) - issue2550920 - Registration with confirmation detects duplcate name when using validation. Added option to allow detection of duplicate username when the user tries to register. Previously user was rejected when confirming registration. (John Rouillard) - French translation gave errors with Python 3 because of ISO-8859-1 character in .mo file header. (Joseph Myers) - Fix representation of boolean html attributes to be 'required' rather than the xhtml form of 'required="required"'. Specify (reverted attribute value same as attribute name or) attribute value of None, to output attribute as boolean. (John Rouillard) Reverted (part of) this change. It breaks rendering of non-boolean attributes (like name="name"). So only value of None renders attribute properly as boolean. (Ralf Schlatterbeck) - issue2551076 - in responsive template, default searches for bugs and tasks sets status=new default should be "don't care". (Report: Ludwig Reiter; Fix: John Rouillard) - issue2551077 - In "jinja2" template: cannot login if German language is used. Fixed three places where the value of a hidden @action input field was translated. (Reported by Ludwig Reiter. John Rouillard) - Document security issues in xmlrpc interface in doc/xmlrpc.txt. - Enable autoescape in the jinja2 template and use the i18n extension for translations. (Report: John Rouillard; Fix: Christof Meerwald) - Cleanup code by linting using flake8. (John Rouillard) - Cleanup code by security linting using bandit. (John Rouillard) - issue2550912 - fixed missing query string in __came_from for jinja2 template. (Christof Meerwald) - issue2551019 - handle character set conversions for CSV export action in Python 3. (Christof Meerwald) - issue2551051: Return a 403 on non-existing or non-searchable transitive properties when queried via REST-API (same behavior for sorting and searching). - Fixed ReStructuredText encoding with Python 3. -- -- rouilj John Rouillard

[RELEASE] Python 3.9.0b4 is now ready for testing
by Łukasz Langa 04 Jul '20

04 Jul '20

On behalf of the entire Python development community, and the currently serving Python release team in particular, I’m pleased to announce the release of Python 3.9.0b4. Get it here: https://www.python.org/downloads/release/python-390b4/ <https://www.python.org/downloads/release/python-390b4/> This is a beta preview of Python 3.9 Python 3.9 is still in development. This release, 3.9.0b4, is the fourth of five 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. Call to action We strongly encourage maintainers of third-party Python projects to test with 3.9 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 (2020-08-10). Our goal is have no ABI changes after beta 5 and as few code changes as possible after 3.9.0rc1, the first release candidate. To achieve that, it will be extremely important to get as much exposure for 3.9 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. Major new features of the 3.9 series, compared to 3.8 Some of the new major new features and changes in Python 3.9 are: PEP 584 <https://www.python.org/dev/peps/pep-0584/>, Union Operators in dict PEP 585 <https://www.python.org/dev/peps/pep-0585/>, Type Hinting Generics In Standard Collections PEP 593 <https://www.python.org/dev/peps/pep-0593/>, Flexible function and variable annotations PEP 602 <https://www.python.org/dev/peps/pep-0602/>, Python adopts a stable annual release cadence PEP 615 <https://www.python.org/dev/peps/pep-0615/>, Support for the IANA Time Zone Database in the Standard Library PEP 616 <https://www.python.org/dev/peps/pep-0616/>, String methods to remove prefixes and suffixes PEP 617 <https://www.python.org/dev/peps/pep-0617/>, New PEG parser for CPython BPO 38379 <https://bugs.python.org/issue38379>, garbage collection does not block on resurrected objects; BPO 38692 <https://bugs.python.org/issue38692>, os.pidfd_open added that allows process management without races and signals; BPO 39926 <https://bugs.python.org/issue39926>, Unicode support updated to version 13.0.0; BPO 1635741 <https://bugs.python.org/issue1635741>, when Python is initialized multiple times in the same process, it does not leak memory anymore; A number of Python builtins (range, tuple, set, frozenset, list, dict) are now sped up using PEP 590 <https://www.python.org/dev/peps/pep-0590> vectorcall; A number of Python modules (_abc, audioop, _bz2, _codecs, _contextvars, _crypt, _functools, _json, _locale, operator, resource, time, _weakref) now use multiphase initialization as defined by PEP 489 <https://www.python.org/dev/peps/pep-0489/>; A number of standard library modules (audioop, ast, grp, _hashlib, pwd, _posixsubprocess, random, select, struct, termios, zlib) are now using the stable ABI defined by PEP 384 <https://www.python.org/dev/peps/pep-0384/>. (Hey, fellow core developer, if a feature you find important is missing from this list, let Łukasz know <mailto:lukasz@python.org>.) The next pre-release, the fifth beta release of Python 3.9, will be 3.9.0b5. It is currently scheduled for 2020-07-20.

by M.-A. Lemburg 02 Jul '20

02 Jul '20

We’re happy to announce our keynote lineup for EuroPython 2020. * EuroPython 2020 Keynotes * https://ep2020.europython.eu/events/keynotes/ Guido van Rossum - Q&A ---------------------- In this session, you’ll get a chance to get your questions answered by Guido van Rossum, our retired BDFL. In order to submit a question, please use the following Google form: Guido van Rossum Q&A: Question Submission: https://forms.gle/cAaBgUeVEBgjaDrH7 Siddha Ganju - 30 Golden Rules of Deep Learning Performance ----------------------------------------------------------- “Watching paint dry is faster than training my deep learning model.” “If only I had ten more GPUs, I could train my model in time.” “I want to run my model on a cheap smartphone, but it’s probably too heavy and slow.” If this sounds like you, then you might like this talk. Exploring the landscape of training and inference, we cover a myriad of tricks that step-by-step improve the efficiency of most deep learning pipelines, reduce wasted hardware cycles, and make them cost-effective. We identify and fix inefficiencies across different parts of the pipeline, including data preparation, reading and augmentation, training, and inference. With a data-driven approach and easy-to-replicate TensorFlow examples, finely tune the knobs of your deep learning pipeline to get the best out of your hardware. And with the money you save, demand a raise! Naomi Ceder - Staying for the Community: Building Community in the face of Covid-19 ------------------------------------------ Python communities around the world, large and small are facing loss - from the loss of in person meetups and conferences to the loss of employment and even the potential loss of health and life. As communities we are all confronting uncertainty and unanswered questions. In this talk I would like to reflect on some of those questions. What are communities doing now to preserve a sense of community in the face of this crisis? What might we do and what options will we have for coming events? How can we build and foster community and still keep everyone safe? What challenges might we all face in the future? What sources of support can we find? What are our sources of optimism and hope? Alejandro Saucedo - Meditations on First Deployment: A Practical Guide to Responsible Development ---------------------------------------------------- As the impact of software increasingly reaches farther and wider, our professional responsibility as developers becomes more critical to society. The production systems we design, build and maintain often bring inherent adversities with complex technical, societal and even ethical challenges. The skillsets required to tackle these challenges require us to go beyond the algorithms, and require cross-functional collaboration that often goes beyond a single developer. In this talk we introduce intuitive and practical insights from a few of the core ethics themes in software including Privacy, Equity, Trust and Transparency. We cover their importance, the growing societal challenges, and how organisations such as The Institute for Ethical AI, The Linux Foundation, the Association for Computer Machinery, NumFocus, the IEEE and the Python Software Foundation are contributing to these critical themes through standards, policy advise and open source software initiatives. We finally will wrap up the talk with practical steps that any individual can take to get involved and contribute to some of these great open initiatives, and contribute to these critical ongoing discussions. EuroPython 2020 is waiting for you ---------------------------------- We’ve compiled a full program for the event: - more than 120 sessions, - more than 120 speakers from around the world, - 4 brilliant keynotes, - 2 exciting lightning talk blocks, - 4 all-day tracks, with a whole track dedicated to data science topics, - a poster track, - a virtual social event, - an after party, - and lots of socializing on our conference platform. Conference tickets are available on our registration page. We hope to see lots of you at the conference from July 23-26. Rest assured that we’ll make this a great event again — even within the limitations of running the conference online. https://ep2020.europython.eu/registration/buy-tickets/ Help spread the word -------------------- Please help us spread this message by sharing it on your social networks as widely as possible. Thank you !

cx_Freeze: transfer of maintenance to Marcelo Duarte
by Anthony Tuininga 02 Jul '20

02 Jul '20

All, In the past few years I have realized that I no longer use cx_Freeze myself and my spare time to maintain cx_Freeze is limited. In the past number of months Marcelo Duarte has been doing much of the work of responding to issues and creating pull requests to continue enhancing cx_Freeze. As such, as of today I am transferring the maintenance of cx_Freeze to him. I will continue to be available for consultation but this is a formal recognition that the bulk of the work is now being performed by Marcelo. I wish him all the best! The new repository is: https://github.com/marcelotduarte/cx_Freeze Anthony
