[baseline 0.2.1] Easy String Baseline
by Dan Gass March 30, 2020

March 30, 2020

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)

Vulture 0.29
by Jendrik Seipp July 31, 2018

July 31, 2018

Vulture - Find dead code ======================== Vulture finds unused code in Python programs. This is useful for cleaning up and finding errors in large code bases. If you run Vulture on both your library and test suite you can find untested code. Due to Python's dynamic nature, static code analyzers like Vulture are likely to miss some dead code. Also, code that is only called implicitly may be reported as unused. Nonetheless, Vulture can be a very helpful tool for higher code quality. Download ======== https://github.com/jendrikseipp/vulture http://pypi.python.org/pypi/vulture Features ======== * fast: uses static code analysis * tested: tests itself and has complete test coverage * complements pyflakes and has the same output syntax * sorts unused classes and functions by size with ``--sort-by-size`` * supports Python 2.7 and Python >= 3.4 News ==== * Add ``--ignore-names`` flag for ignoring names matching the given glob patterns (thanks @RJ722). Cheers Jendrik

ANN: poliastro 0.10.0 released 🚀
by Juan Luis Cano July 20, 2018

July 20, 2018

Hi all, It fills us with astronomical joy to announce the release of poliastro 0.10.0! 🚀 poliastro is a pure Python library that allows you to simulate and analyze interplanetary orbits in a Jupyter notebook in an interactive and easy way, used in academia and the industry by people from all around the world. You can install it using pip or conda: pip install poliastro conda install poliastro --channel conda-forge This release was specially important in terms of development, and there are major changes in the structure of the code, several performance improvements, and many infrastructure changes. In particular, to pick only one highlight, we now have a website displaying benchmarks created using Airspeed Velocity: http://poliastro.github.io/poliastro-benchmarks In terms of new features, the most important one is the addition of continuous thrust (or low thrust) guidance laws for some orbital maneuvers, which means that now you can simulate spiral trajectories and much more. You can read the full release notes in the documentation: http://docs.poliastro.space/en/v0.10.0/changelog.html#poliastro-0-10-0-2018… By popular demand, the next release will be focused on improving reference frame handling in Orbit objects, which hopefully will fix one of the long standing pain points with poliastro. If you want to know more, don't miss my talk on the Open Source Cubesat Worshop held at the European Space Operations Centre: https://youtu.be/KnoYzqAw_vM?t=1h36m14s Please join our chat on Matrix/Riot and feel free to ask any questions you might have: https://riot.im/app/#/room/#poliastro:matrix.org Per Python ad astra! -- Juan Luis Cano

Fwd: Package maintainers: verify your PyPI account email address
by Sumana Harihareswara July 19, 2018

July 19, 2018

If you maintain any PyPI packages, please verify your address on PyPI. Details below. -------- Forwarded Message -------- Subject: Package maintainers: verify your PyPI account email address Date: Mon, 16 Jul 2018 21:57:38 -0400 From: Sumana Harihareswara <sh(a)changeset.nyc> To: DistUtils mailing list <distutils-sig(a)python.org> Heads-up: if you have a pypi.org or test.pypi.org account, please verify your email address: https://pypi.org/manage/account/ https://test.pypi.org/manage/account/ Reason: > We have a problem with a bit of our data, namely that due to historical reasons we have a fair amount of users in the database that do not have a verified primary email address. The side effect of this is that we're currently sending emails to email addresses that we have not had verified. This is a bad situation to be in, because in order to keep our bounce/spam rate low, we should be confirming all email addresses before sending email to them. In addition the way our bounce handling code works is it un-verifies the email address, which the intent was to stop sending email to it until the user has reverified their email address. > > In total there are about 193k user accounts with a unverified email address for their primary address, and 44k that do have a verified email address for their primary account. > > So we need to come up with a strategy to resolve this, because it's pretty important that we don't send email to unverified addresses. (quoting from Donald Stufft's explanation https://github.com/pypa/warehouse/issues/3632 which goes on to detail the step-by-step plan) Package maintainers should especially do this soon. As of a few days ago, any user whose primary email address is unverified can't upload a file: https://github.com/pypa/warehouse/pull/4292 Please forward to other package maintainers. After we iron out any issues I figure we'll email the announce list https://mail.python.org/mm3/mailman3/lists/pypi-announce.python.org/ . -- Sumana Harihareswara Changeset Consulting https://changeset.nyc

PyCA cryptography 2.3 released
by Paul Kehrer July 18, 2018

July 18, 2018

PyCA cryptography 2.2.2 has been released to PyPI. cryptography includes both high level recipes and low level interfaces to common cryptographic algorithms such as symmetric ciphers, message digests, and key derivation functions. We support Python 2.7, Python 3.4+, and PyPy. Changelog (https://cryptography.io/en/latest/changelog/#v2-3): * SECURITY ISSUE: finalize_with_tag() allowed tag truncation by default which can allow tag forgery in some cases. The method now enforces the min_tag_length provided to the GCM constructor. * Added support for Python 3.7. * Added extract_timestamp() to get the authenticated timestamp of a Fernet token. * Support for Python 2.7.x without hmac.compare_digest has been deprecated. We will require Python 2.7.7 or higher (or 2.7.6 on Ubuntu) in the next cryptography release. * Fixed multiple issues preventing cryptography from compiling against LibreSSL 2.7.x. * Added get_revoked_certificate_by_serial_number for quick serial number searches in CRLs. * The RelativeDistinguishedName class now preserves the order of attributes. Duplicate attributes now raise an error instead of silently discarding duplicates. * aes_key_unwrap() and aes_key_unwrap_with_padding() now raise InvalidUnwrap if the wrapped key is an invalid length, instead of ValueError. -Paul Kehrer (reaperhulk)

learning by contributing to FLOSS (and pygame in specific)
by René Dudfield July 18, 2018

July 18, 2018

Hello, I'm looking for a small group of 10-30 people who are interested in contributing to the pygame project as part of a class or user group meeting. Rather than a normal user group meeting or class, it could be: "contribute to an open source project". Be in touch!? Let's do it! :) *Why?* (teaching by helping people contribute to FLOSS projects.) Because you don't learn karate from a book. Builds social connections and skills. Portfolio, and evidence of talent. Sort of fun and different compared to a talks night at a user group. *Why pygame?* (rather than some other project) Because I want to do this with my pet project. It's sort of fun compared to some topics (better than watching paint dry at least). Because it's sort of well known project (millions of users). ... with almost zero full time or even part time developers (that's why it's called pygame zero). Because I will help before and during the class(es)/session(s), and have resources and issues prepared. *[hey! you could totally do this with your own pet projects too!]* *How will a gathering work?* *The goal*: At the end of the gathering, people will have learned how a FLOSS project is done, submitted a PR, and have a big thank you posted on the website. A session could run like this: 1. A short lightning talk can be done on what's happening by someone on how to write a unit test, and what is a github issue (slides can be made available). 2. A number of topics will be presented to choose from. These will be 'low hanging fruit' issues. Like, "write a test for a draw rectangle functions". 3. People will split off into small groups of 2-4 people. Each choosing an issue. Probably beginners and experts will be mixed together. 4. Project developers will be available via web chat (Discord) (or in person perhaps if it's where the developers live...). 5. results will be pasted into issues, and perhaps even pull requests made. 6. At the end one person from each group will show off what they've done and experienced to the group. (several short talks) [Hrmm... you may be thinking that this sort of sounds exactly like a Dojo (shout out to London Python Dojo) or mini conference sprint format(shout out to pypy!). Yop.) If anyone wants to do this with me please be in touch to get this going! I will announce when it's happening so people can drop by online too if they want. cheers,

[ANN] - Skyline v1.2.2-stable-luminosity
by Gary Wilson July 17, 2018

July 17, 2018

For those interested in anomaly detection and deflection in streamed time series data. I would like to announce a new release of Skyline v1.2.2 - https://github.com/earthgecko/skyline/releases/tag/v1.2.2-stable-luminosity What is Skyline? ---------------- Skyline v1.2.2 - For those interested in anomaly detection and deflection in streamed time series data. Anomaly deflection. The obvious next evolution in the use of all the anomaly detection data? Skyline is a Python based anomaly detection/deflection stack that analyses, anomaly detects, deflects, fingerprints and learns vast amounts of streamed time series data. - Skyline ingests streamed metric time series data - skyline/horizon - Skyline uses a ```CONSENSUS``` of 3-sigma algorithms to detect anomalies on batch processed, streamed metric time series data - skyline/analyzer - anomaly detector - It handles large and small seasonality in the data - skyline/mirage - anomaly deflector and detector - You can train it on what is NOT anomalous and it learns - skyline/ionosphere - anomaly deflector - It records all your anomalies - skyline/panorama - anomaly memory - It shows you all your data - skyline/webapp - anomaly view Seeing as we desire our metrics to be not anomalous most of the time and we want to know when they ARE anomalous and given the fact that we try and build systems that try to behave within not anomalous bounds so they perform well, due to this we have: - A lot of metric time series data that are not anomalous most of the time. - A lot of data to train a system on what is NOT anomalous given a time series data set, rather than simply focusing on what is anomalous, also focusing on what is not anomalous. To achieve this Skyline implements a novel time series similarities comparison algorithm and a boundary layers methodology that generates fingerprints of time series data using the sum of the values of features of the time series which have been extracted using the tsfresh features extraction package - https://github.com/blue-yonder/tsfresh and evaluation against boundary layer algorithms to determine whether a 3-sigma triggered anomaly is actually a normal, known pattern in the data. The Skyline-Ionosphere-Tsfresh Time Series Similairities Comparison Algorithm - SITTSSCA first coined here :) compares the generated fingerprints of the two time series and can determine if they closely resemble each other in terms of: - of the amount of "power/energy", range and "movement" there is within the time series data set somewhat like RMS - Erol Kalkan from United States Geological Survey, “Another approach to compute the differences between two time series is moving window root-mean-square. RMS can be run for both series separately. This way, you can compare the similarities in energy (gain) level of time series. You may vary the window length for best resolution.” (https://www.researchgate.net/post/How_can_I_perform_time_series_data_simila…) http://stackoverflow.com/questions/5613244/root-mean-square-in-numpy-and-co… The Skyline-Ionosphere-Tsfresh Time Series Similairities Comparison Algorithm compares how close the fingerprint values are as a percentage and varying this percentage variable will either focusing the algorithm with greater precision the closer to 0% the parameter gets, the perfect match (or possibly a mirror match too - unkonwn/untested) or it will incrementally increase the tolerance as the percentage variable increases and the matching will become less and less reliable. However there is a sweet spot and here SITTSSCA works extremely well :) Added to SITTSSCA is an optional layer of simple boundary algorithms that are user defined during the operator training interaction with Skyline, where the operator augments the SITTSSCA results with boundaries that describe the expected norm within the time series. Very similar to being able to describe the Active Brownian Motion of a time series - https://github.com/blue-yonder/tsfresh/pull/143#issuecomment-272314801 This results in an anomaly detection/deflection system which enables the user to very simply label time series and train Skyline on the peaks and troughs and the expected Active Brownian Motion or best effort thereof. However it takes a little effort on your part to train Skyline, however with the effort, Skyline is very good at doing anomaly detection and deflection. With your help. There is no easy anomaly detection or deflection, but there is some reward with a bit of effort. To learn more... ---------------- Project page -> https://github.com/earthgecko/skyline Documentation -> https://earthgecko-skyline.readthedocs.io/en/latest/index.html With the hope Skyline can make the universe a bit less anomalous.

ANN: Numexpr 2.6.6
by Robert McLeod July 16, 2018

July 16, 2018

========================== Announcing Numexpr 2.6.6 ========================== Hi everyone, This is a bug-fix release. Thanks to Mark Dickinson for a fix to the thread barrier that occassionally suffered from spurious wakeups on MacOSX. Project documentation is available at: http://numexpr.readthedocs.io/ Changes from 2.6.5 to 2.6.6 --------------------------- - Thanks to Mark Dickinson for a fix to the thread barrier that occassionally suffered from spurious wakeups on MacOSX. What's Numexpr? --------------- Numexpr is a fast numerical expression evaluator for NumPy. With it, expressions that operate on arrays (like "3*a+4*b") are accelerated and use less memory than doing the same calculation in Python. It has multi-threaded capabilities, as well as support for Intel's MKL (Math Kernel Library), which allows an extremely fast evaluation of transcendental functions (sin, cos, tan, exp, log...) while squeezing the last drop of performance out of your multi-core processors. Look here for a some benchmarks of numexpr using MKL: https://github.com/pydata/numexpr/wiki/NumexprMKL Its only dependency is NumPy (MKL is optional), so it works well as an easy-to-deploy, easy-to-use, computational engine for projects that don't want to adopt other solutions requiring more heavy dependencies. Where I can find Numexpr? ------------------------- The project is hosted at GitHub in: https://github.com/pydata/numexpr You can get the packages from PyPI as well (but not for RC releases): http://pypi.python.org/pypi/numexpr Documentation is hosted at: http://numexpr.readthedocs.io/en/latest/ Share your experience --------------------- Let us know of any bugs, suggestions, gripes, kudos, etc. you may have. Enjoy data! -- Robert McLeod, Ph.D. robbmcleod(a)gmail.com robbmcleod(a)protonmail.com robert.mcleod(a)hitachi-hhtc.ca www.entropyreduction.al

Invitation to the EuroPython Society General Assembly 2018
by M.-A. Lemburg July 15, 2018

July 15, 2018

We would like to invite all EuroPython attendees and EuroPython Society (EPS) members to attend this year’s EPS General Assembly (GA), which we will run as in-person meeting at the upcoming EuroPython 2018, held in Edinburgh, Scotland, UK from July 23 - 29. We had already sent a invite to the members mailing on 2018-06-17, but would like to announce this more broadly as well and with complete agenda. Place of the General Assembly meeting ------------------------------------- We will meet on Friday, July 27, at 14:15 BST in room Kilsyth of the EICC, The Exchange, Edinburgh EH3 8EE. There will be a short talk to invite volunteers to participate in organizing EuroPython 2019 in preparation for next year’s event at 14:00 BST in the same room, right before the General Assembly. You may want to attend that talk as well. In this talk, we will present the EuroPython Workgroup Concept, we have been using successfully for the past years now. General Assembly Agenda ----------------------- The agenda contents for the assembly is defined by the EPS bylaws. We are planning to use the following structure: - Opening of the meeting - Selection of meeting chair, secretary and 2 checkers of the minutes - Motion establishing the timeliness of the call to the meeting - Presentation of the annual report and annual accounts by the board - Presentation of the report of the auditor - Discharge from liability for the board - Presentation of a budget by the outgoing board. - Acceptance of budget and decision on membership fees for the upcoming year - Election of members of the board - Election of chair of the board - Election of one auditor and one replacement. The auditor does not have to be certified in any way and is normally selected among the members of the society. - The optional election of a nomination committee for the next annual meeting of the General Assembly - Propositions from the board, if any - Motions from the members, if any - Closing of the meeting In an effort to reduce the time it takes to go through this long list, which is mandated by the bylaws, we will try to send as much information to the members mailing list before the GA, so that we can limit presentations to a minimum. Election of the members of the board ------------------------------------ The EPS bylaws limit the number of board members to one chair and 2 - 8 directors, at most 9 directors in total. Experience has shown that the board members are the most active organizers of the EuroPython conference, so we try to get as many board members as possible to spread the work load. All members of the EPS are free to nominate or self nominate board members. Please write to board(a)europython-society.org no later than Friday, July 20 2017, if you want to run for board. We will then include you in the list we’ll have in the final nomination announcement before the GA, which is scheduled for July 21. The following people from the current board have already shown interest in running for board in the next term as well (in alphabetical order): - Anders Hammarquist - Darya Chyzhyk - Marc-André Lemburg We will post more detailed information about the candidates and any new nominations we receive in a separate blog post. Propositions from the board --------------------------- We would like to propose to grant CPython Core Developers a lifetime free entry to EuroPython conferences in recognition for their efforts to build the foundation on what our community is built. The details are to be defined by the EPS board. The bylaws allow for additional propositions to be announced up until 5 days before the GA, so the above list is not necessarily the final list. Motions from the members ------------------------ None at the moment. EPS members are entitled to suggest motions to be voted on at the GA. The bylaws require any such motions to be announced at least 5 days before the GA. If you would like to propose a motion, please send it to board(a)europython-society.org no later than Friday, July 20 2017, so we can announce the final list to everyone. Help spread the word -------------------- Please help us spread this message by sharing it on your social networks as widely as possible. Thank you !

Twisted 18.7 Release Announcement
by Amber Brown July 13, 2018

July 13, 2018

On behalf of Twisted Matrix Laboratories, I am honoured to announce the release of Twisted 18.7! The highlights of this release are: - better support for async/await coroutines in regards to exception and traceback handling; - better support for reporting tracebacks in inlineCallbacks, now showing what you would expect in synchronous-like code - the epoll reactor now no longer hard-locks when running out of file descriptors - directory rendering in t.web works on Python 2 again - manhole's colouriser is better at handling Unicode - setting the groundwork for Python 3.7 support. Note that Python 3.7 is currently not a supported platform on any operating system, and may completely fail to install, especially on Windows. For more information, check the NEWS file (link provided below). You can find the downloads at <https://pypi.python.org/pypi/Twisted> (or alternatively <http://twistedmatrix.com/trac/wiki/Downloads>). The NEWS file is also available at <https://github.com/twisted/twisted/blob/twisted-18.7.0/NEWS>. Many thanks to everyone who had a part in this release - the supporters of the Twisted Software Foundation, the developers who contributed code as well as documentation, and all the people building great things with Twisted! Twisted Regards, Amber Brown (HawkOwl)

Roundup Issue Tracker version 1.6.0 released
by John P. Rouillard July 13, 2018

July 13, 2018

Hello all: After two and half years of work by the Roundup Team, I'm proud to release version 1.6.0 of Roundup which has been possible due to the help of several contributors. This release contains important security enhancements, so make sure to read `docs/upgrading.txt <http://www.roundup-tracker.org/docs/upgrading.html>`_ to bring your tracker up to date. Other changes, as usual, include some new features and many bug fixes. If you're upgrading from an older version of Roundup you *must* follow the "Software Upgrade" guidelines given in the maintenance documentation. Roundup requires python 2.7 or later (but not 3+) for correct operation. 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/mail/?group_id=31577 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. 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+ (but not 3+) 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 minimal skeleton; * a more extensive devel tracker for bug/features etc. * a responsive version of the devel tracker * a jinja2 based template based on devel and four database back-ends (anydbm, sqlite, mysql and postgresql). New Features in 1.6.0 (ordered by implementation date): - issue2550894: migrate test suite and run_test.py to py.test (John Kristensen) - issue2550880: Ability to choose password store scheme and SSHA support. Discussion on devel list is tending in favor of this patch. Embedded test works, my manual test with a SSHA password assigned to a user allowed the user to log in. Ran the test suite and the tests that were not skipped passed. (applied by John Rouillard) - New Link/Multilink property attribute 'msg_header_property', can be used to configure additional headers in outgoing emails. See documentation in ``doc/customizing.txt``. (Ralf Schlatterbeck) - Allow multiple file uploads: If the html template specifies multiple="multiple" for a file upload the user can attach multiple files and the form parser now handles this. (Ralf Schlatterbeck) - issue2550886: Add support for an integer type to join the existing number type. This can be used for properties used for ordering, counts etc. where a decimal point isn't needed. Developed by Anthony (antmail). Doc updates written by John Rouillard. (applied by John Rouillard) - Updated html/_generic.404.html to use the page template. So 404 errors now include the left hand menu, a proper page title and body content. Note added to doc/upgrading.txt on how to add it to deployed trackers. (John Rouillard) - issue2109308 - Allow subject of nosy messages be changed from reactor Adds a subject parameter to nosymessage function. Patch initally generated by Frank Niessink. Tests, adaptation by John Rouillard. - issue2550683 Allow indexargs_form filter variable exclusion. Patch generated by Bruce Tulloch (bruce). Applied and docstring for indexargs_form updated by John Rouillard. Patch description is: This is required to allow indexargs_form to be used in conjunction with other form variables which *replace* some filterspec parameters. One must exclude all variables from the indexargs_form call which are to be replaced with values that are derived from other form input elements, otherwise they will clash with the "hidden" input elements generated by indexargs_form itself. For example:: <tal:block replace="structure python:request.indexargs_form( sort=0,group=0,filter=0,columns=0, exclude=['type','status','assignedto'])"/> where the variables type, status and assignedto are supplied via other form input elements. Without the new exclude argument to indexargs_form, all hidden input elements otherwise generated by this call would need to be manually added to the template code. Further, given that the template may not know what other variables may be defined, it may not even be possible to code this without some python helpers. [rouilj I think this is an example usecase. Possible assignedto users need to have a specific role. Create TAL that filters the users to the select few. Defines a select list for assignedto. Use exclude=['assignedto'] to prevent the indexargs_form from generating a confliciting assignedto field which lists all users regardless of the role.] - allow user to recover account password using an entry in the Alternate E-mail addresses list. See:: http://psf.upfronthosting.co.za/roundup/meta/issue564 for description. Merge request at:: https://sourceforge.net/p/roundup/code/merge-requests/1/ Patch supplied by kinggreedy. Applied/tested by John Rouillard - issue2550636, issue2550909: Added support for Whoosh indexer. Also adds new config.ini setting called indexer to select indexer. See ``doc/upgrading.txt`` for details. Initial patch done by David Wolever. Patch modified, docs added and committed by John Rouillard. - issue2550803: Replying to NOSY mail goes to the tracker through reply-to, not original message author. Created new [tracker] replyto_address config.ini option to allow: 1) setting reply-to header to the tracker 2) setting reply-to header to the address of the author of the change 3) setting it to a fixed address (like noreply(a)some.place) Done by John Rouillard from proposal by Peter Funk (pefu) in discussion with Tom Ekberg (tekberg). See doc/upgrading.txt. - issue1714899: Feature Request: Optional Change Note. Added a new quiet=True/False option for all property types. When quiet=True changes to the property will not be displayed in the:: * confirmation banner (shown in green) when a change is made * property change section of change note (nosy emails) * web history display for an item. Note that this may confuse users if used on a property that is meant to be changed by a user. It is most useful on administrative properties that are changed by an auditor as part of a user generated change. Original patch by Daniel Diniz (ajaksu2) discussed also at: http://psf.upfronthosting.co.za/roundup/meta/issue249 Support for setting quiet when calling the class specifiers. E.G. prop=String(quiet=True) rather than:: prop=String() prop.quiet=True support for anydb backend, added tests, doc updates, support for ignoring quiet setting using showall=True in call to history() function in templates by (John Rouillard). (Note implementation changed while implementing fix for issue2550864. Filtering of quiet properties pushed down to the hyperdb.py::Class::history function. This fixes a small bug in the implementation that caused a limiting the templating history call to display fewer than the requested number of items if some were quiet.) - issue2550767: Add newitemcopy.py detector to notify users of new items. Added to detectors directory and a README.txt generated to describe the purpose of the directory. It also says the detectors are provided on an as-is basis and may not work. Detector by W. Trevor King (wking), rest by John Rouillard. - issue934009: Have New Issues Submitted By Email *Not* Change Body! The mailgw config options: keep_quoted_text and leave_body_unchanged can now have a new values: new. If set to new, keep_quoted_text acts like yes if the message is starting a new issue. Otherise it strips quoted text. This allows somebody to start a new issue by forwarding a threaded email (with multiple quoted parts) into roundup and keeping all the quoted parts. If leave_body_unchanged is set to new, even the signature on the email that starts a new issue will be preserved. - New cgi action restore (RestoreAction) which reverses the effects of the retire action. Created while implementing fix for issue2550831. Requires restore permission in the schema. See upgrading.txt for migrating to 1.6.0 for details. (John Rouillard) - issue2550751: Email Header Issue. Noel Garces requested the ability to suppress email headers like "x-roundup-issue-files". With Ralf's addition of the Link/Multilink property attribute 'msg_header_property' we can do this easily. Setting the 'msg_header_property' to the empty string '' (not to None) will suppress the header for that property. (John Rouillard) - issue2550891: Allow subdir in template value. Anthony (antmail) requested the ability to put templates into subdirectories. So the issue class can accept @template=issues/item to get the html/issues/issue.item.html template. See ``doc/upgrading.txt``. - issue1842687: Keywords: After creating, stay in "Create New" mode. Change to classic tracker template to provide a check box (checked by default) that keeps the user on the "Add new keyword" page after submitting a new keyword. Usually after submission, you will see the page for the new keyword to allow you to change the name of the keyword. (John Rouillard) - issue2550757 - internal restructuring to allow admin.py to be tested more easily. W. Trevor King (wking)/ John Rouillard. - When storing user-defined queries we now store the template with the query if the template name is different from 'index'. This allows stored queries for templates different from the default 'index' template. (Ralf Schlatterbeck) - Number properties now have an optional attribute use_double to request double precision float as the storage type for this property. (Ralf Schlatterbeck) - issue2550796: Calendar and Classhelp selection tools don't cause onchange event to be triggered. Using the helper popups for modifying lists of users, lists of issues, dates etc.. now trigger the change event on the form's field. This allows onchange javascript to trigger to highlight changes, recalculate other form values etc. See ``upgrading.txt`` for details on applying these changes to your tracker. (John Rouillard) - menu template function has a new parameter "showdef". When set to a string, the string is appended to the displayed option value. This allows the user to reset the value for the menu (select) to the original value. (John Rouillard) - @template html url parameter can be set to "oktmpl|errortmpl". When a form is submitted, if the form passes validation the oktmpl is used for the resulting page. If the form fails submission the errortmpl page is used to display the form. The errortmpl will usually be the same template used to edit the form. See the section on "Implementing Modal Editing Using @template" in ``customizing.txt``. (John Rouillard) - New form of check function is permitted in permission definitions. If the check function is defined as:: check(db, userid, itemid, **ctx) the ctx variable will have:: ctx['property'] the name of the property being checked or None ctx['classname'] the class that is being checked or None ctx['permission'] the name of the permission (e.g. View, Edit) At some future date the older 3 argument style check command will be deprecated. See ``upgrading.txt`` for details. - New property for permissions added to simplify the model. See ``customizing.txt`` and search for props_only and set_props_only_default in the section 'Adding a new Permission'. (John Rouillard) - issue2550690 - Inadequate CSRF protection. Improvements in Cross Site Request Forgery protection to check HTTP headers and nonces. If the header/nonce is present, they are validated. But if headers or nonces are missing access is granted. The enforcement policy can be set in config.ini. Requiring enforcement will need some changes to templates. Support for protecting xmlrpc endpoint not well tested. See ``upgrading.txt``. (John Rouillard) - Added support for using the SameSite cookie option on the session cookie. Default is lax, but there is a settable option in config.ini file to change to strict or suppress it entirely. See ``upgrading.txt``. (John Rouillard) - Added a new roundup-admin command: updateconfig. Similar to genconfig but it uses values from an existing config.ini rather than default values. Use to update an existing config.ini with new options and help text. (John Rouillard) - issue2550864: Potential information leakage via journal/history Hyperdb history function now only returns properties that the user can View or Edit and links to objects the user can see. Can be overridden by setting a parameter when calling the method. Also restructured code that implemented issue1714899 moving it from the templating class to the hyperdb. (John Rouillard) - Improves diagnostics for mail processing: When using logging level = DEBUG, bounces and bounce problems are logged. (Bernhard Reiter) - In roundup-server, pass X-Forwarded-For and X-Forwarded-Proto headers as the environment variables: HTTP_X-FORWARDED-FOR and HTTP_X_FORWARDED_PROTO. If the user is running roundup server behind a proxy, these headers allow the user to write extensions that can figure out the original client ip and protocol. None of the core roundup code uses these headers/env vars. These headers can be spoofed by bad proxies etc. so you have been warned. - issue2550799: provide basic support for handling html only emails Emails missing text/plain parts but with text/html parts can be converted into text. If this is done the email will no longer be bounced back to the sender with an error. Enable by configuring the convert_htmltotext option in your upgraded config.ini. (Initial patch by Igor Ippolitov merged with changes by John Rouillard.) - Add a 'retired' parameter to Class.filter to allow searching for retired, non-retired or all (retired and non-retired) items similar to the argument of the same name to Class.getnodeids. This is 'False' by default (finding only non-retired items for backwards compatibility) and can be set to None (for finding retired and non-retired items) or True (for finding only retired items). - Requires Python 2.7 now, indicated in version_check.py and doc/installation.txt. (Bernhard Reiter) - New -L flag to roundup-server to send http/https request logs through the python logger module (using roundup.http). This allows automatic log rotation. Without it, log file rotation requires restarting the server. (John Rouillard) - Part of issue2550960. Applied patch 0038 to upgrade documentation code examples to support both python 2 and 3. (Joseph Myers) Bugs fixed in 1.6.0: - issue1615201: Optionally restore the original (version 0.6) mailgw behaviour of ignoring a Resent-From:-header and using the real From-header instead: new configuration option EMAIL_KEEP_REAL_FROM (Peter Funk aka Pefu). - issue2550717: Changed a couple of residual email references into E-Mail in German translation (John Rouillard) - issue2550669: Adding documentation for csv_field_size to the customizing tracker section of doc/customizing.txt (John Rouillard) - issue2550601: gsoc-2009 "bug" class doesn't have "patches" property Added multilink to patches to the bug schema in the devel template. (applied by John Rouillard) - issue2550748: Crash when creating new issues with non-existing multilink values (in classic template). Applied patch so it now errors the same way as an update does. (applied by John Rouillard) - issue2550757: one bug raised by issue fixed. Patch created by W. Trevor King (wking) for documentation of mailgw applied by John Rouillard. - Fix processing of additional arguments to cgi method 'menu': This would not work if more than one additional argument is used. (Ralf Schlatterbeck) - Update documentation of some existing property attributes (like 'do_journal' for Link/Multilink properties), this also adds missing documentation for issue1444214. (Ralf Schlatterbeck) - issue2550763 Strip whitespace from Multilink values after + or -. (W. Trevor King) Test heavily modified by John Rouillard. (applied by John Rouillard) - issue2550907 Fix errors when creating documentation. Work done by Peter Funk (pefu). (Applied by John Rouillard with small change omitting obsolete security.txt.) - issue2550826 Capture some exceptions from auditors/reactors and raise a DetectorError instead. This allows failures like IOErrors from the detectors (e.g. unable to access files) to be handled. Previously an IOError just resulted in no output (premature end of headers under apache). Problem diagnosed and initial patch created by Tom Ekberg (tekberg). Further testing and patch change done by John Rouillard. - issue2550851 in installation doc removed directions for installing additional codecs for Asian languages. They they appear to be part of the standard python since at least 2.6. Also the quoted url is obsolete. See ticket if you think you need the codecs. - issue2550823 improve mailgw logging for node creation errors. Patch by r.david.murray (applied by John Rouillard). - issue2550549 Postgres error on message templating Exception gets thrown and not captured if nodeid is too large on postgres. Added a check in rdbms_common layer that max nodeid is < 2^31 -1. Large nodeid now return no such id error upstream. Patch idea from: martin.v.loewis. (John Rouillard) - issue2550723 Fix propagation of @pagesize When @pagesize=0 is specified (indicating show all), the value of pagesize is not propigated to the prev link. This patch fixes that. Patch provided by John Kristensen. (Applied, light testing by John Rouillard.) - issue2550850 anypy/email\_.py uses BSPACE which is not defined in python 2.7 Supplied a definition for BSPACE since it seems to not be defined anywhere. Reported by Dennis Boone. (John Rouillard) - Validate properties specified for sorting and grouping in index views. Original patch from martin.v.loewis via: https://hg.python.org/tracker/roundup/rev/439bd3060df2 Applied by John Rouillard with some modification to properly identify if the bad property is a sort or grouping property. Tests added. - Validate Integer and Numeric type filter parameters rather than passing output down to db level. Initial patch at: http://hg.python.org/tracker/roundup/rev/98508a47c126 by Martin.V.Loewis. Numeric test patch applied, Integer code and tests developed by John Rouillard. - issue1926124: fix crash in roundup_admin migrate option. Patch submitted by Henry (henryl), modified value to False since this produces the correct "No migration action required" output from the migrate command. - issue2161722: oudated docs (sic) Fix old entry in FAQ, update roundup-server config docs and example file from current roundup-server output. Update some typos in .py files. John Rouillard. - issue2550572: setting nosy=+foo on multiple issues gives them all the same exact nosy list. Fixed a missing reinitialization that has to occur every time though the loop in do_set. Manual tests work. (John Rouillard) - issue2550653: xapian search, stemming is not working This is a partial fix for the issue. It does make stemming work (so searching for silent will also return docs with silently in them). However to do this we need to lowercase the text so the porter stemmer will work. This means capitalization is not preserved. Fix done by David Wolever (wolever). Committed and doc updates John Rouillard. - issue2550855: "show unassigned" link shows all open issues if not logged in. This adds permission for the anonymous user to search the users class. Without this the unassigned search can't see if there is a user assigned to an issue, so it acts like all open issues. Patch supplied by Stuart McGraw (smcgraw). For caveats see ``upgrading.txt`` and the comments in the default templates. (Docs created and applcation by John Rouillard) - issue2550854: including new field in All text* search. Fixed documentation in customizing.txt. The default for indexme on String fileds is 'no' not 'yes'. So to get a new string field into the full text/all text index you need to use String(indexme='yes'). Reported by Michael Belleville. (John Rouillard) - issue2550853 - better error handling and cleanup on some postgres tests by Stuart McGraw. - issue2086536 - back_postgresql: fixing pg_command and prefering psycopg2. Patch done by Philipp Gortan (mephinet). His patch also improves handling of retryable errors. Applied and edited by John Rouillard. Edits included removing support for psycopg1. See: https://sourceforge.net/p/roundup/mailman/message/32855027/ for rational for dropping it. - issue2550831: Make the classic template query.edit page work. Many fixes and improvements. See ``upgrading.txt`` for details. Diagnosis and fix with patch by R David Murray. Support for restoring retired but active queries, html layout changes and doc by John Rouillard. - issue2550785: Using login from search (or logout) fails. When logging in from a search page or after a logout it fails with an error. These failures have been fixed. The fix also keeps the user on the same page they started from before the login. There are two parts to this: 1) changes to the templates to properly define the __came_from form element. See ``upgrading.txt``. 2) code changes to the LoginAction code in roundup/cgi/actions.py. (John Rouillard) - issue2550648 - partial fix for problem in this issue. Ezio Melotti reported that the expression editor allowed the user to generate an expression using retired values. To align the expression editor with the simple dropdown search item, retired values are now removed from the expression editor. (We have an open question as to whether this is desirable.) - issue2550743 - Reindex with MySQL Server failed. It looks like indexing large documents may require increasing mysql's max_allowed_packet setting. Documented the issue in doc/mysql.txt. Possible solutions include: increasing value of MySQL parameter, changing the full text search engine to whoosh or xapian. Problem report by telsch. Analysis/doc by John Rouillard. - issue2550882. Reported by Karl-Philipp Richter. Fixed installation.txt documentation to include better directions on starting roundup-server on different ports/ip addresses. Also updated man page to include default use of localhost for -n and use of -n 0.0.0.0 to bind to all addresses on the host. (John Rouillard) - issue2550827, issue2550718. Doc additions so people know that a python 32 bit installation may be required for windows. Additional documentation on the requirement of pywin32 for running roundup as a windows service. Also the windows installer must be run as administrator and strong encouragement for installing the pytz module added to ``doc/installation.txt``. - issue2550776: imapServer.py problem. Fixed a missing initialization of the logging level if no logging level option is supplied. (John Rouillard) - issue2550839: Xapian, DatabaseLockError: Unable to get write lock on db/text-index: already locked. Put in a retry loop that will attempt to get the lock. Total delay approx 4.5 seconds. (John Rouillard) - issue2550727: db.newid is broken with sqlite. Added proper transaction lock around the sql code to get a new id. The locking that pysqlite attempts had to be defeated because it is broken. Had to explicitly manage transactions with BEGIN IMMEDIATE and call sql_commit. Note that this reduces performance in return for accuracy. Problem reported by Matt Mackall (mpm) (John Rouillard). - issue2550701: Path traversal from template names. This affects the tal based template engines (zopetal, chameleon). If a directory with a specific name is created in the html subdirectory, the template name in the url can be used to get access to files outside of the tracker html directory. This has been fixed by normalizing the path and comparing to the normalized path for the html directory. See ``doc/upgrading.txt``. (John Rouillard) - Fix subject parsing in mail gateway. The previous parsing routine would not ensure that arguments are at the end of the subject and when subject_suffix_parsing was configured to be 'loose' it would truncate the subject when encountering a double prefix, e.g. Subject: [frobulated] [frobulatedagain] this part would be lost (Ralf Schlatterbeck) - issue2550795: @dispname query args in page.html search links not valid html. Some queries with names that include spaces are not properly url encoded/quoted. I.E. a space should be replaced with %20. Fixes to allow a url_query method to be applied to HTMLStringProperty to properly quote string values passed as part of a url. - issue2550755: exceptions.NotFound(msg) msg is not reported to user in cgi. When an invalid column is specified return error code 400 rather than 404. Make error code 400 also return an error message to the user. Reported by: Bernhard Reiter, analysis, fix by John Rouillard. - issue1408570: Finally fix that form values are lost on edit exceptions. This occured for example if editing an issue with the classic template and setting 'superseder' to a non-existing issue number. All changes to the form where the original field was non-empty were lost. (Ralf Schlatterbeck) - Fix submit_once Javascript function: This needs to return a boolean value (not and integer like 0 or 1). And the work-around for an ancient version of Internet Explorer would make it break for a recent Firefox. The old version would show the popup but after clicking away the alert it would load the page. The new version (tested with Chromium and Firefox) doesn't load the page. (Ralf Schlatterbeck) - Fix Traceback in backends/portalocker.py on windows due to missing windll import, thanks to Heiko Stegmann for suggesting a first fix. (Ralf Schlatterbeck) - issue2550933 - Fix Traceback in cgi/templating.py when a string is passed to PasswordHTMLProperty::plain. (John Rouillard) - issue2550934 - templating.py-indexargs_form() returns id's as space separated list not comma separated. This fixes the format of the id url parameter when generated by indexargs_form. (John Rouillard) - issue2550932 - html_calendar produces templating errors for bad date strings. Fixed to ignore bad date and highlight todays date in the calendar popup. - Query handling requires that query names for a user are unique. Different users are allowed to use the same query name. Under some circumstances a user could generate a second query with the same name. The SearchAction function has been corrected to report this error. Also the index.search.html template in the classic tracker and corresponding templates in the other example trackers has been modified to include:: <input type="hidden" name="@template" value="index|search"/> so an error from SearchAction will display an error message and keep the user on the search page so they can correct the error. See ``doc/upgrading.txt``. (John Rouillard) - When a new named search is created, the index page that is displayed doesn't show the name. This has been fixed by setting the @dispname to the query's name. (John Rouillard) - Passing args into indexargs_url(..,{'@queryname': request/dispname or None, 'Title': 'some' }) where the value of the arg is None will not add the arg to the url. In the example above @queryname will only be in the url if dispname is set in the request. (John Rouillard) - The HTMLClass::properties() method produced a list of properties that the user could not search. As a result these properties can not be used for sorting or grouping index pages. This patch eliminates the confusion that results from this mismatch by verifying that all properties returned are searchable. (John Rouillard) - Mutilinks can be displayed with their labelprop using the plain() method, but they can not be looped over using tal:repeat if the user doesn't have view access to the class the multilink represents. The permissions check was changed to require that the user have View access to the labelprop for the class rather than View access to the class. (John Rouillard) - issue2550937: fix crash by verifying that sendto is not null before calling mailer.smtp_send. Discovered and patched by Trent Gamblin. Applied by John Rouillard. - removed old code from roundup-admin that implemented the obsolete config (do_config) command. (John Rouillard) - Modified configuration option static_files to be a space separated list of directories to search for static files in the web interface. If one of the elements is -, the search stops and the TEMPLATES directory is not searched. See: https://sourceforge.net/p/roundup/mailman/message/35773357/ subject is "showing template sources to all". - issue2550945: OpenPGP: Extends newissuecopy.py to encrypt if configured. (Bernhard Reiter) - CSRF protection broke the retire function for query edit. Fix javascript and make sure csrf tokens are provided in the right places. (John Rouillard) - query.item.html was missing checks to verify that a query should be visible to the user. This is fixed and users can only view queries that they own or that are not private. (John Rouillard) - issue2550953: Patch: fix for context.is_view_ok check in jinja2 template Form controls are displayed when anonymous views indexes but is denied access. (patch by Anton Schur applied by John Rouillard) - issue2550957: Duplicate emails (with patch). Bcc and cc users passed to nosymessage are not properly recorded. This results in duplicate emails. (patch by Trent Gamblin (trentgg) applied by John Rouillard). - issue2550954: History display breaks on removed properties Now changes to removed properties, and link/unlink events from non-existing properties or classes no longer trigger a traceback. Concerning the visibility: We have a new config-item obsolete_history_roles in the main section that defines which roles may see removed properties. By default only role Admin is allowed to see these. - Fix issue2550955: Roundup commits although a Reject exception is raised Fix the problem that changes are committed to the database (due to commits to otk handling) even when a Reject exception occurs. The fix implements separate database connections for otk/session handling and normal database operation. - Allow empty content property for file and message via xmlrpc interface. This used to raise a traceback in the (sql) backend. - Work around a limitation in python2.7 implementation of poplib (for the pop3 protocol for fetching emails): It seems poplib applies a line-length limit not just to the lines involving the pop3 protocol but to any email content, too. This sometimes leads to tracebacks whenever an email exceeding this limit is encountered. We "fix" this by monkey-patching poplib with a larger line-limit. Thanks to Heiko Stegmann for discovering this. -- -- rouilj John Rouillard =========================================================================== My employers don't acknowledge my existence much less my opinions.

[ANN] PyYAML-3.13: YAML parser and emitter for Python
by Ingy dot Net July 5, 2018

July 5, 2018

======================== Announcing PyYAML-3.13 ======================== A new bug fix release of PyYAML is now available: http://pyyaml.org/wiki/PyYAML *** Important Note From Maintainers *** This is the first PyYAML release by the new maintainers. It was made critical because PyYAML-3.12 did not work with the recent Python 3.7 release. A more ambitious 4.1 release was attempted last week and needed to be retracted for many reasons. We apologize any pain caused by the 4.1 removal, but we remain confident that it was the best decision. There are over 60 pull requests in PyYAML and LibYAML that will be represented in the upcoming 4.2 release and we are working hard to get those to you as soon as the release is ready (but no sooner :). We are are excited that the PyYAML project is moving forward again. -- The PyYAML Maintenance Team Changes ======= * Rebuilt with the latest Cython to support the new Python 3.7 release. * No functionality is different from PyYAML 3.12 in this release. Resources ========= PyYAML IRC Channel: #pyyaml on irc.freenode.net YAML IRC Channel: #yaml-dev on irc.freenode.net LibYAML IRC Channel: #libyaml on irc.freenode.net PyYAML homepage: http://pyyaml.org/wiki/PyYAML PyYAML documentation: http://pyyaml.org/wiki/PyYAMLDocumentation Source and binary installers: https://pypi.python.org/pypi/PyYAML/3.13 GitHub repository: https://github.com/yaml/pyyaml/ Bug tracking: https://github.com/yaml/pyyaml/issues YAML homepage: http://yaml.org/ YAML-core mailing list: http://lists.sourceforge.net/lists/listinfo/yaml-core About PyYAML ============ YAML is a data serialization format designed for human readability and interaction with scripting languages. PyYAML is a YAML parser and emitter for Python. PyYAML features a complete YAML 1.1 parser, Unicode support, pickle support, capable extension API, and sensible error messages. PyYAML supports standard YAML tags and provides Python-specific tags that allow to represent an arbitrary Python object. PyYAML is applicable for a broad range of tasks from complex configuration files to object serialization and persistance. Example ======= >>> import yaml >>> yaml.load(""" ... name: PyYAML ... description: YAML parser and emitter for Python ... homepage: http://pyyaml.org/wiki/PyYAML ... keywords: [YAML, serialization, configuration, persistance, pickle] ... """) {'keywords': ['YAML', 'serialization', 'configuration', 'persistance', 'pickle'], 'homepage': 'http://pyyaml.org/wiki/PyYAML', 'description': 'YAML parser and emitter for Python', 'name': 'PyYAML'} >>> print yaml.dump(_) name: PyYAML homepage: http://pyyaml.org/wiki/PyYAML description: YAML parser and emitter for Python keywords: [YAML, serialization, configuration, persistance, pickle] Maintainers =========== The following people are currently responsible for maintaining PyYAML: * Ingy döt Net * Tina Mueller * Matt Davis and many thanks to all who have contribributed!

Vulture 0.28
by Jendrik Seipp July 5, 2018

July 5, 2018

Vulture - Find dead code ======================== Vulture finds unused code in Python programs. This is useful for cleaning up and finding errors in large code bases. If you run Vulture on both your library and test suite you can find untested code. Due to Python's dynamic nature, static code analyzers like Vulture are likely to miss some dead code. Also, code that is only called implicitly may be reported as unused. Nonetheless, Vulture can be a very helpful tool for higher code quality. Download ======== https://github.com/jendrikseipp/vulture http://pypi.python.org/pypi/vulture Features ======== * fast: uses static code analysis * tested: tests itself and has complete test coverage * complements pyflakes and has the same output syntax * sorts unused classes and functions by size with ``--sort-by-size`` * supports Python 2.7 and Python >= 3.4 News ==== * Add ``--make-whitelist`` flag for reporting output in whitelist format (thanks @RJ722). * Ignore case of ``--exclude`` arguments on Windows. * Add ``*-test.py`` to recognized test file patterns. * Add ``failureException``, ``longMessage`` and ``maxDiff`` to ``unittest`` whitelist. * Refer to actual objects rather than their mocks in default whitelists (thanks @RJ722). * Don't import any Vulture modules in setup.py (thanks @RJ722). Cheers Jendrik

PyCon ZA 2018 - Second Call for Speakers
by Neil Muller July 4, 2018

July 4, 2018

This is a second call for talk proposals for PyCon ZA 2018. 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 2018 will take place on the 11th & 12th of October at The Birchwood Hotel & Conference Centre, in Boksburg North, Johannesburg, South Africa (location link: https://goo.gl/maps/XMtwhJCKVt92 ). There will also be tutorial sessions the day before the conference (the 10th) and we will hold sprints on the 13th & 14th of October. We are currently accepting proposals for talks. 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: Web, Scientific-Computing/PyData, Testing and Other (which includes all talks that don't fall under the mentioned tracks). Talk submissions close io the 31st of August 2018, ad we hope to inform speakers by the second week of September. If you need an earlier decision for travel planning, please add a note with your deadline to your submission. The presentation slots will be 30 minutes long, with an additional 10 minutes for discussion at the end. 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 draft of your talk proposal and we'll find a suitable experienced speaker to act as a mentor. In addition to talks, we are also looking for proposals for tutorials, demos, sprints and open spaces. Tutorials will be held before the conference and are expected to provided in-depth coverage of a topic. The number of attendees will be also be limited. We are accepting proposals for either half day (4 hours) or full-day (8 hours) tutorials. The deadline for tutorial submissions is the 27th of July 2018, and we'll inform people of our decision in early August. Demos are cool things for attendees to see and interact with. Open spaces are open discussion forums where communities with a common interest gather to present views, ask questions and meet people interested in the topic. Sprints are coding efforts and hack days that happen after the conference. There is no need to register a sprint or open space topic upfront, but doing so allows us to advertise them during the conference. Limited financial assistance for attendees is available. See https://za.pycon.org/financial-aid/ for details on how to apply. Each submission will be reviewed on a case-by-case basis. -- Neil Muller On behalf of the PyCon ZA organising committee

by M.-A. Lemburg July 3, 2018

July 3, 2018

Over the last few weeks, our program WG has been working hard on getting the schedule all lined up. Today, we’re releasing it to the Python world. Schedule for EuroPython 2018 * https://ep2018.europython.eu/en/events/schedule/ * With 140 speakers and more than 150 sessions, we have a full packed program waiting for you. Please note that the schedule may still change in details, but the overall layout is fixed now. Book your EuroPython 2018 Ticket -------------------------------- Please make sure you book your ticket in the coming days. We will switch to late bird rates closer to the event. If you want to attend the training sessions, please buy a training pass. We only have very few left and will close sales for these later this week. Travel & accommodation tips --------------------------- Since we’re close the conference and The Fringe is starting a week later, Edinburgh is in high demand. If you’re having problems finding a hotel, please also consider searching for apartments on the well known booking sites. For traveling to Edinburgh, we suggest also considering a combination of plane and train or bus. London, Birmingham and Manchester all provide train and bus lines going to Edinburgh and by booking a combination, you can often save a lot, compared to a direct flight to Edinburgh. Help spread the word -------------------- Please help us spread this message by sharing it on your social networks as widely as possible. Thank you !

Let’s all meet at EuroPython ---------------------------- In addition to the Python Organizers Lunch (see previous post), which focuses on conference organizers, we are also establishing a program to support attendees of Python user groups and conferences in Europe. We’d like to invite all of you to EuroPython 2018 this year. Of course, we cannot give out free tickets to everyone, but we can at least recognize your participation in the Python community by giving out discounts for the conference. Discounts for EuroPython Tickets -------------------------------- If you are running a Python event (conference or user group) in Europe, please reach out to board(a)europython.eu to request a coupon code for your group, which you can then pass on to your group members or attendees. If you are not running a user group or conference, but a regular attendee of one, please contact your organizers to have them submit a request. We can only distribute codes at the user group and conference organizer level. The coupon codes are valid for conference tickets bought starting today and will give you a 10% discount on the ticket price (both regular and late bird prices). The codes are setup for user group sizes of between 30-50 members, but we are also extending this to organizers and attendees of larger conferences. If you need a code valid for larger groups, please mention this in your email. Help spread the word -------------------- Please help us spread this message by sharing it on your social networks as widely as possible. Thank you !

The EuroPython Society (EPS), who is organizing the EuroPython conference, last year extended it’s mission to also provide help for the Python community in Europe in general. As part of this, we would like to get to know, and help create closer ties between organizers of other European Python events. Organizers’ Lunch ----------------- We would like to invite representatives of all European Python conference to EuroPython 2018 to join us for an organizers’ lunch. We’re planing the lunch for Friday, July 27, in the organizer’s room (Soutra Suite). Our aim is to get to know each other, exchange experience in organizing events and to find out how we, as EPS, can most effectively help other conferences going forward. Free Tickets ------------ To support and facilitate this, we are giving out one free conference ticket per conference team, so that each team can send a representative to the organizers’ lunch. If your team wants to send someone to join, please write to board(a)europython.eu, mentioning the conference you’re organizing and some background on your team. Help spread the word -------------------- Please help us spread this message by sharing it on your social networks as widely as possible. Thank you !
