NestedText 3.0
by NestedText 19 Jul '21

19 Jul '21

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

by Marc-Andre Lemburg 16 Jul '21

16 Jul '21

The EuroPython Society (EPS) exists not only to run the EuroPython Conference, but also to support the wider Python community in Europe. It accomplishes this in many ways; here are two of them! * EuroPython Society supporting the community * https://blog.europython.eu/europython-2021-conference-organizers-community-… Organisers' Lunch ----------------- We have an open invitation for organisers responsible for other Python conferences around Europe to attend lunch with us. The aim is for us all to get to know each other and share advice on running events, as well as determine how we, the EPS, can support other events. To enable this, we are offering one free conference ticket per conference team, to ensure that each event can send a representative. If you would like to avail of this, please email board(a)europython.eu to introduce yourselves, your event and the background of your team. The lunch is planned for the Thursday or Friday of the event, and finalised details will be announced closer to the conference. Community Discounts ------------------- In addition to the aforementioned lunch, we would also like to support individuals who attend conferences and smaller user groups around Europe. Although we cannot offer free tickets, we would like to offer discounted tickets to local communities. If you are a regular attendee to Python events, please direct your local organisers to this post; they may submit a request for this community discount, and will be responsible for distributing them to the people who attend their events. If you are responsible for organising Python events, please reach out to board(a)europython.eu in order to obtain a discount code for your attendees, encouraging them to engage with the global Python community. These discount codes will provide 10% off all ticket prices; they are intended for groups of 30-50 members, but we can provide codes for larger groups as long as this requirement is mentioned in your initial contact email.

pythran 0.9.12 - heskenn
by Serge Guelton 13 Jul '21

13 Jul '21

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 13 Jul '21

13 Jul '21

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. Address timing attack to discover valid account names. Useful where anonymous user is not allowed access. (John Rouillard) - issue2551126 - AttributeError: 'str' object has no attribute 'local'. Fix traceback caused by DateHTMLProperty.pretty() called on a string value due to error in some other field. (Reported by reda, fix: John Rouillard) - issue2550899 - Migrate setup.py to setuptools; fixes: issue2550866 'pip install --editable .' fails; et al. this now requires that setuptools be installed. (Patch by John Kristensen (jerrykan); additional doc changes (upgrade.txt, RELEASE.txt) John Rouillard) - issue2551128 - Impossible to validate a user with unknown timezone Raise KeyError when an unrecognized timezones is passed to pytz. (patch Cedric Krier, test John Rouillard) - issue2551129 - Template not found return 500 Handle traceback caused when requested @template is not found. Return 400 error in this condition. (patch Cedric Krier, additional change and test John Rouillard) - issue2551062: roundup-admin security now exits status 1 when it finds an invalid property. It no longer tries to print the rest of the security properties. (John Rouillard) - issue2551078 - Fix traceback caused when putting two id's into a Link html field. A ValueError is raised. Handle exception and return value. hyperdb.py now reports 'you may only enter ID values for property ...' to the user. (John Rouillard) - issue2551120 - The sorted method of MultilinkHTMLProperty crashes, if the given property is unset for an element of the list. Crash fixed. New feature NoneFirst added to method to make unset values sort at start or end of sorted list. (John Rouillard) - issue2550648 - keyword boolean search. Issue has multiple problems. Fix issue where saving the keyword boolean search would remove the link to open the editor. (John Rouillard) - issue2551136 - timezone extention crash on Python 3.8. cgi.escape is used in some template to provide a select box of timezones. It uses cgi.escape that is deprecated and removed from 3.8 and newer. Use html.escape with fallback to cgi.escape. (Cedric Krier) - roundup-server can act as an SSL server. Usually SSL is provided by a front-end server like nginx, hiawatha, apache. The SSL parameters have been upgraded to TLS 1.1. Cert is RSA 2048 bytes with SHA512 signature. Without these upgrades, ssl mode won't start. Note this exposes other issue with roundup-server operating as an SSL endpoint. See issue2551138 and issue2551137. (John Rouillard) - issue2551122 - sorted method of MultilinkHTMLProperty does a string sort even if the property is an integer. Fixed so that the orderprop for the linked class is used. (John Rouillard, reported by Nagy Gabor) - issue2550964 - History can (temporarily) show incorrect value when a change is rejected. Fix history function to always use the database values and ignore the current setting in the form. (John Rouillard) - Fix find() with anydbm. Using protected properties raised KeyError. Add shortcut fast return. Both changes come from rdbms_common.py's find(). (John Rouillard) - Fix traceback caused by calling history() with arguments in a non-item context. (John Rouillard) - issue2551141 - roundup-admin returns no such class when restoring item with duplicate key. Fix incorrect error message when using roundup-admin to restore a user when the username is already in use. (John Rouillard) - issue2551142 - Import of retired node with username after active node is imported raises unique constraint failure. (Reported by Ganesh Sittampalam/Heffalump on irc. John Rouillard) - *** Must run roundup-admin migrate *** Increment rdbms version from 5 to 6. Mysql rdbms classes were missing unique key constraint. Found during fix for issue2551142. See upgrading.txt. (John Rouillard) - ignore blank lines in CSV class editing. (John Rouillard) - issue2551122 - fixing order by a link/multilink broke other props should be final change for that ticket. (John Rouillard) Features: - issue2550522 - Add 'filter' command to command-line interface. Filter command was actually added in 2.0.0, but this issue requested transitive searching. So that:: roundup-admin -i . filter issue assignedto.username=Admin will work. This also fixes a bug. If assignedto.username had no matches, all issues would be returned. This is also fixed. (John Rouillard) - issue2550716 - Email address displayed after password reset request. This fix actually made it into 1.6 release. However this release documents how password reset works in user_guide.txt. (John Rouillard) - issue2551094 - add new markdown config.ini setting to allow embedded newlines to cause a linebreak same as GitHub Flavored Markdown. (Patch: Cedric Krier; Doc change/checkin John Rouillard) - issue2551096 - enable markdown autolink for email and bare url's. Modify raw markdown adding appropriate link markers on the fly. (Cedric Krier) - issue2551098 - add rel="nofollow" for links generated by markdown2 backend and rel="nofollow noopener" for mistune and markdown backends. Prevents link spam. noopener prevents security issue when available. (John Rouillard) - Added explanation for modifying Fileclass content files to customizing.txt. Result of mailing list question. (John Rouillard) - issue2551109 - Improve keyword editing in jinja2 template. (Cedric Krier) - issue2551117 - Add example systemd config - Allow admin to configure language used for stemming in xapian indexer. (John Rouillard request by Nagy Gabor) - Move memorydb from test to roundup/test to allow regression-testing in tracker instances without copying code. Also move the test-detectors in tx_Source_detector.py to roundup/test for two reasons: It's used in the memorydb convenience functions and it may be useful in other tests. Make the prefix a parameter of the convenience functions to be usable in other tests. (Ralf Schlatterbeck) - pytest suite now starts the server under wsgi and loads the home page. This test is skipped if the requests module is not installed. - extract translatable strings from devel and responsive templates. Merge translations from https://sourceforge.net/p/roundup/code/merge-requests/3/ (John Rouillard. DE translations by Tobias Herp.) - send_message now allows setting authid to set source of email. (John Rouillard) - issue2550837 - New option for web auth (also http header passing). Allow admin to configure authentication header replacing the default REMOTE_USER. Also allow arbitrary headers to be passed to the tracker when using roundup-server behind a proxy. This code is experimental see upgrading.txt admin_guide.txt. (John Rouillard) - add image/svg-xml as valid mime type to serve. Was being served as octet-stream. (John Rouillard) - improve customizing.txt documentation on use of Special Form Variables. Added example html inputs to illustrate the doc. Fix position of designator in doc example. It occurs before @link@ or other edit command.

PyConZA 2021 - Second call for submissions
by Neil Muller 12 Jul '21

12 Jul '21

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
