Cheetah 3.3.3
by Oleg Broytman 22 Oct '23

22 Oct '23

Hello! I'm pleased to announce version 3.3.3, the fourth release of branch 3.3 of CheetahTemplate3. What's new in CheetahTemplate3 ============================== Minor features: - Protect ``import cgi`` in preparation to Python 3.13. Tests: - Run tests with Python 3.12. CI: - GHActions: Ensure ``pip`` only if needed This is to work around a problem in conda with Python 3.7 - it brings in wrong version of ``setuptools`` incompatible with Python 3.7. What is CheetahTemplate3 ======================== Cheetah3 is a free and open source (MIT) Python template engine. It's a fork of the original CheetahTemplate library. Python 2.7 or 3.4+ is required. Where is CheetahTemplate3 ========================= Site: https://cheetahtemplate.org/ Download: https://pypi.org/project/CT3/3.3.3 News and changes: https://cheetahtemplate.org/news.html StackOverflow: https://stackoverflow.com/questions/tagged/cheetah Mailing lists: https://sourceforge.net/p/cheetahtemplate/mailman/ Development: https://github.com/CheetahTemplate3 Developer Guide: https://cheetahtemplate.org/dev_guide/ Example ======= Install:: $ pip install CT3 # (or even "ct3") Below is a simple example of some Cheetah code, as you can see it's practically Python. You can import, inherit and define methods just like in a regular Python module, since that's what your Cheetah templates are compiled to :) :: #from Cheetah.Template import Template #extends Template #set $people = [{'name' : 'Tom', 'mood' : 'Happy'}, {'name' : 'Dick', 'mood' : 'Sad'}, {'name' : 'Harry', 'mood' : 'Hairy'}] <strong>How are you feeling?</strong> <ul> #for $person in $people <li> $person['name'] is $person['mood'] </li> #end for </ul> Oleg. -- Oleg Broytman https://phdru.name/ phd(a)phdru.name Programmers don't die, they just GOSUB without RETURN.

Guppy 3/Heapy 3.1.4
by YiFei Zhu 20 Oct '23

20 Oct '23

I am happy to announce Guppy 3 3.1.4 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 release adds support for Python 3.12, and support for Python 3.7 was dropped. This release also fixes a few bug fixes, including: o Fix refcount sanity assertion for Python 3.11, when C asserts are compiled in. o Fix INTERATTR definition, where for "internal attributes" it would always report the attribute name as "newname". o Fix .referrers occasionally returning empty set due to GC race License: MIT The project homepage is on GitHub: https://github.com/zhuyifei1999/guppy3 Enjoy, YiFei Zhu

Pieshell version 0.2.7 (With async/await support)
by Egil Möller 17 Oct '23

17 Oct '23

Pieshell is a Python shell environment that combines the expressiveness of shell pipelines with the power of python iterators. This release adds support for async/await and async iterators for all shell pipelines, as well as MacOS X support. Pieshell can be used as an interactive shell replacing e.g. bash or imported as an ordinary python module, providing a superset of the functionality of subprocess.Popen etc. Example of what Pieshell lets you do: for name in ls | grep("-e", ".pyc"): rm(name)

ANN: psutil 5.9.6 released
by Giampaolo Rodola' 15 Oct '23

15 Oct '23

Hello all, I'm glad to announce the release of psutil 5.9.6: https://github.com/giampaolo/psutil 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 2.7 and 3.6+. PyPy is also known to work. What's new ========== 2023-10-15 **Enhancements** - #1703: `cpu_percent()`_ and `cpu_times_percent()`_ are now thread safe, meaning they can be called from different threads and still return meaningful and independent results. Before, if (say) 10 threads called ``cpu_percent(interval=None)`` at the same time, only 1 thread out of 10 would get the right result. - #2266: if `Process`_ class is passed a very high PID, raise `NoSuchProcess`_ instead of OverflowError. (patch by Xuehai Pan) - #2246: drop python 3.4 & 3.5 support. (patch by Matthieu Darbois) - #2290: PID reuse is now pre-emptively checked for `Process.ppid()`_ and `Process.parents()`_. - #2312: use ``ruff`` Python linter instead of ``flake8 + isort``. It's an order of magnitude faster + it adds a ton of new code quality checks. **Bug fixes** - #2195, [Linux]: no longer print exception at import time in case /proc/stat can't be read due to permission error. Redirect it to ``PSUTIL_DEBUG`` instead. - #2241, [NetBSD]: can't compile On NetBSD 10.99.3/amd64. (patch by Thomas Klausner) - #2245, [Windows]: fix var unbound error on possibly in `swap_memory()`_ (patch by student_2333) - #2268: ``bytes2human()`` utility function was unable to properly represent negative values. - #2252, [Windows]: `disk_usage()`_ fails on Python 3.12+. (patch by Matthieu Darbois) - #2284, [Linux]: `Process.memory_full_info()`_ may incorrectly raise `ZombieProcess`_ if it's determined via ``/proc/pid/smaps_rollup``. Instead we now fallback on reading ``/proc/pid/smaps``. - #2287, [OpenBSD], [NetBSD]: `Process.is_running()`_ erroneously return ``False`` for zombie processes, because creation time cannot be determined. - #2288, [Linux]: correctly raise `ZombieProcess`_ on `Process.exe()`_, `Process.cmdline()`_ and `Process.memory_maps()`_ instead of returning a "null" value. - #2290: differently from what stated in the doc, PID reuse is not pre-emptively checked for `Process.nice()`_ (set), `Process.ionice()`_, (set), `Process.cpu_affinity()`_ (set), `Process.rlimit()`_ (set), `Process.parent()`_. - #2308, [OpenBSD]: `Process.threads()`_ always fail with AccessDenied (also as root).

Vulture 2.10
by Jendrik Seipp 06 Oct '23

06 Oct '23

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` News ==== * Drop support for Python 3.7 (Jendrik Seipp, #323). * Add support for Python 3.12 (Jendrik Seipp, #332). * Use `end_lineno` AST attribute to obtain more accurate line counts (Jendrik Seipp). Cheers, Jendrik
