[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 … [View More]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) [View Less]

ANN: psutil 5.7.0 released
by Giampaolo Rodola' Feb. 27, 2020

Feb. 27, 2020

Hello all, I'm glad to announce the release of psutil 5.7.0: 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, … [View More]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 ========== 2020-12-18 **Enhancements** - #1637: [SunOS] add partial support for old SunOS 5.10 Update 0 to 3. - #1648: [Linux] sensors_temperatures() looks into an additional /sys/device/ directory for additional data. (patch by Javad Karabi) - #1652: [Windows] dropped support for Windows XP and Windows Server 2003. Minimum supported Windows version now is Windows Vista. - #1671: [FreeBSD] add CI testing/service for FreeBSD (Cirrus CI). - #1677: [Windows] process exe() will succeed for all process PIDs (instead of raising AccessDenied). - #1679: [Windows] net_connections() and Process.connections() are 10% faster. - #1682: [PyPy] added CI / test integration for PyPy via Travis. - #1686: [Windows] added support for PyPy on Windows. - #1693: [Windows] boot_time(), Process.create_time() and users()'s login time now have 1 micro second precision (before the precision was of 1 second). **Bug fixes** - #1538: [NetBSD] process cwd() may return ENOENT instead of NoSuchProcess. - #1627: [Linux] Process.memory_maps() can raise KeyError. - #1642: [SunOS] querying basic info for PID 0 results in FileNotFoundError. - #1646: [FreeBSD] many Process methods may cause a segfault on FreeBSD 12.0 due to a backward incompatible change in a C type introduced in 12.0. - #1656: [Windows] Process.memory_full_info() raises AccessDenied even for the current user and os.getpid(). - #1660: [Windows] Process.open_files() complete rewrite + check of errors. - #1662: [Windows] process exe() may raise WinError 0. - #1665: [Linux] disk_io_counters() does not take into account extra fields added to recent kernels. (patch by Mike Hommey) - #1672: use the right C type when dealing with PIDs (int or long). Thus far (long) was almost always assumed, which is wrong on most platforms. - #1673: [OpenBSD] Process connections(), num_fds() and threads() returned improper exception if process is gone. - #1674: [SunOS] disk_partitions() may raise OSError. - #1684: [Linux] disk_io_counters() may raise ValueError on systems not having /proc/diskstats. - #1695: [Linux] could not compile on kernels <= 2.6.13 due to PSUTIL_HAVE_IOPRIO not being defined.
