logassert v6
by Facundo Batista 25 Oct '20

25 Oct '20

logassert is a simple log assertion mechanism for Python unittests. Why? As is vox populi, you must also test the logging calls in your programs. With logassert this is now very easy. In this version: - Simple way to check that nothing was logged (on any level or a specific one): assert NOTHING in logs.debug - Helper to check that several lines were logged one after the other: assert Sequence( "Got 1 error and \d+ warnings:", Exact(" error: bar"), ) in logs.debug - Show proper message when "not in" assertion is used (thanks Diego Mascialino) Regards, -- .

ANN: psutil 5.7.3 released
by Giampaolo Rodola' 24 Oct '20

24 Oct '20

Hello all, I'm glad to announce the release of psutil 5.7.3: https://github.com/giampaolo/psutilHere's a blog post explaining the highlights in detail: https://gmpy.dev/blog/2020/freebsd-process-environ-and-resource-limits About ===== psutil (process and system utilities) is a cross-platform library for retrieving information on running processes and system utilization (CPU, memory, disks, network) in Python. It is useful mainly for system monitoring, profiling and limiting process resources and management of running processes. It implements many functionalities offered by command line tools such as: ps, top, lsof, netstat, ifconfig, who, df, kill, free, nice, ionice, iostat, iotop, uptime, pidof, tty, taskset, pmap. It currently supports Linux, Windows, macOS, Sun Solaris, FreeBSD, OpenBSD, NetBSD and AIX, both 32-bit and 64-bit architectures. Supported Python versions are 2.6, 2.7 and 3.4+. PyPy is also known to work. What's new ========== 2020-10-23 **Enhancements** - 809: [FreeBSD] add support for `Process.rlimit()`. - 893: [BSD] add support for `Process.environ()` (patch by Armin Gruner) - 1830: [UNIX] `net_if_stats()`'s `isup` also checks whether the NIC is running (meaning Wi-Fi or ethernet cable is connected). (patch by Chris Burger) - 1837: [Linux] improved battery detection and charge "secsleft" calculation (patch by aristocratos) **Bug fixes** - 1620: [Linux] physical cpu_count() result is incorrect on systems with more than one CPU socket. (patch by Vincent A. Arcila) - 1738: [macOS] Process.exe() may raise FileNotFoundError if process is still alive but the exe file which launched it got deleted. - 1791: [macOS] fix missing include for getpagesize(). - 1823: [Windows] Process.open_files() may cause a segfault due to a NULL pointer. - 1838: [Linux] sensors_battery(): if `percent` can be determined but not the remaining values, still return a result instead of None. (patch by aristocratos) Links ===== - Home page: https://github.com/giampaolo/psutil - Download: https://pypi.org/project/psutil/#files - Documentation: http://psutil.readthedocs.io - What's new: https://github.com/giampaolo/psutil/blob/master/HISTORY.rst -- Giampaolo - https://gmpy.dev/

EuroPython 2021 will be run online
by M.-A. Lemburg 15 Oct '20

15 Oct '20

In the last few weeks, we had a close look at the how the situation around COVID-19 is panning out. Unfortunately, things are not moving in a direction where we’d feel confident to hold next year’s conference as an in-person event in Dublin. EuroPython 2022 in Dublin ------------------------- After discussion with the venue, we decided to postpone the in-person conference for another year, to July 11-17 2022 in Dublin, Ireland. We are currently finalizing the details. Since going online has proven to work well, we also want to keep the momentum for EuroPython 2022 and are planning to run the event in a hybrid version, where both speakers and attendees can optionally join online. EuroPython 2021 Online ---------------------- Given the experience with running EuroPython 2020 online this year, we are sure that EuroPython 2021 will be a success as well. We will take the experience we’ve gained from this year’s event to improve the online version next year, simplify some aspects, reactivate finaid and enable joining it in smaller groups to create a distributed experience. We’re still collecting ideas, so if you have any suggestions, we’d love to hear them. Please write to helpdesk(a)europython.eu. Help spread the word -------------------- Please help us spread this message by sharing it on your social networks as widely as possible. Thank you ! Link to the blog post: https://blog.europython.eu/post/632055258029473792/europython-2021-will-be-… Tweet: https://twitter.com/europython/status/1316759678118961152 Thanks, -- EuroPython Society https://www.europython-society.org/

[ANN] Austin -- CPython frame stack sampler v2.0.0 is now available
by Gabriele 13 Oct '20

13 Oct '20

I am delighted to announce the release 2.0.0 of Austin. If you haven't heard of Austin before, it is an open source frame stack sampler for CPython, distributed under the GPLv3 license. It can be used to obtain statistical profiling data out of a running Python application without a single line of instrumentation. This means that you can start profiling a Python application straightaway, even while it's running on a production environment, with minimal impact on performance. The simplest way of using Austin is by piping its output to FlameGraph for a quick and detailed representation of the collected samples. The latest release introduces a memory profiling mode which allows you to profile memory usage. Austin is a pure C application that has no other dependencies other than the C standard library. Its source code is hosted on GitHub at https://github.com/P403n1x87/austin The README contains installation and usage details, as well as some examples of Austin in action. Details on how to contribute to Austin's development can be found at the bottom of the page. Austin can be installed easily on the following platforms and from the following sources: Linux: - Snap Store - Debian repositories macOS: - Homebrew Windows: - Chocolatey - Scoop Austin is also simple to compile from sources as it only depends on the standard C library, if you don't have access to the above listed sources. Besides support for Python 3.9, this new release of Austin brings a considerable performance enhancement that allows it to sample up to 8 times faster than previous versions. But please do read on until the end to find out about some new tools that take advantage of all the key features of Austin. Due to increasing popularity, the sample Python applications that were included in the main repository have been moved to dedicated projects on GitHub. The TUI can now be found at https://github.com/P403n1x87/austin-tui while Austin Web is now available from https://github.com/P403n1x87/austin-web They can both be installed easily from PyPI, but in order to use them the Austin binary needs to be on the PATH environment variable. These projects now rely on the austin-python Python package that provides a Python wrapper around Austin. If you are considering making your own profiling tool based on Austin, this package can spare you from writing boilerplate code, so it's worth having a look at it at https://github.com/P403n1x87/austin-python The documentation is hosted on RTD at https://austin-python.readthedocs.io/en/latest/ Finally, I am happy to announce the release of pytest-austin, a plugin for pytest that allows you to set up performance regression testing by simply decorating your existing pytest test suite. The plugin launches Austin to profile your test runs, meaning that no further instrumentation is required. For more details, check out the project on GitHub https://github.com/P403n1x87/pytest-austin Like the other Austin tools, pytest-austin can be installed easily from PyPI. You can stay up-to-date with the project's development by following Austin on Twitter (https://twitter.com/AustinSampler). All the best, Gabriele <phoenix1987(a)gmail.com> <p><a href="https://github.com/P403n1x87/austin">Austin 2.0.0</a> - frame stack sampler for CPython. (13-Oct-20)</p>

aiosnow
by Robert Wikman 10 Oct '20

10 Oct '20

Happy to announce a project I've been working on for some time that's finally in beta: aiosnow, a MIT licensed Python 3 client library for interacting with an ITSM cloud service, providing something not too dissimilar to a database ORM. I'm sharing this here as the library makes use of Python asyncio, and other cool features like: - Asynchronous generators, context managers - Query condition chaining using Python bitwise operators - Model Schema system implemented using Marshmallow - The aiohttp library for working with remote HTTP APIs It was built with modularity in mind, and is meant to be forked, hacked and consumed in other projects - commercial or otherwise. What's in it for me? I do this for fun, to learn, and to support the asyncio backend of another project I'm working on, which uses this library at its core. GitHub page: https://github.com/rbw/aiosnow Technical documentation: https://aiosnow.readthedocs.io/en/latest Big thanks to the code contributors and donors! -- Robert Wikman 0xf6feb506ae5d3762

Guppy 3/Heapy 3.1.0
by YiFei Zhu 10 Oct '20

10 Oct '20

I am happy to announce Guppy 3 3.1.0 Guppy 3 is a library and programming environment for Python, currently providing in particular the Heapy subsystem, which supports object and heap memory sizing, profiling and debugging. It also includes a prototypical specification language, the Guppy Specification Language (GSL), which can be used to formally specify aspects of Python programs and generate tests and documentation from a common source. Guppy 3 is a fork of Guppy-PE, created by Sverker Nilsson for Python 2. This is a major feature release. The main news in this release: o Python 3.9 support, without subinterpreter support or inter-interpreter traversal. o Added .byprod classifier via tracemalloc, and .prod to print tracemalloc traceback. o Added .all to print all lines in a MorePrinter buffer. o Added R_INSET relation for being contained by an unordered set.
