Complex numbers
by TBER Abdelmalek 05 Sep '17

05 Sep '17

This module implements cplx class (complex numbers) regardless to the built-in class. The main goal of this module is to propose some improvement to complex numbers in python and deal with them from a mathematical approach. Also cplx class doesn't support the built-in class intentionally, as the idea was to give an alternative to it. With the hope I managed to succeed, here is the module : https://drive.google.com/file/d/0BwTeOOKgEM4aS1JlWUpnZHUwaGs/view?usp=shari…

salabim: a new discrete event simulation package
by Ruud van der Ham 03 Sep '17

03 Sep '17

The package salabim is based on the process description methodology in which processes can be activated, held and passivated.The package supports queues, resources and a very powerful concept of states, which behave a little bit like events. Statistical data collection on queues, resources and states is automatically enabled. The collected data can be shown with matplotlib or exported to R. Animation, which runs parallel to the simulation is one of the most important features of salabim. See www.salabim.org for links to the github page with many examples, the manual and contact information. salabim is also available on PyPI.

ANN: psutil 5.3.0 with full unicode support is out
by Giampaolo Rodola' 03 Sep '17

03 Sep '17

Hello all, I'm glad to announce the release of psutil 5.3.0: https://github.com/giampaolo/psutil A blogpost describing the main changes is available here: http://grodola.blogspot.com/2017/09/psutil-530-with-full-unicode-support-is… 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, OSX, Sun Solaris, FreeBSD, OpenBSD and NetBSD, both 32-bit and 64-bit architectures, with Python versions from 2.6 to 3.5 (users of Python 2.4 and 2.5 may use 2.1.3 version). PyPy is also known to work. What's new ========== **Enhancements** - #802: disk_io_counters() and net_io_counters() numbers no longer wrap (restart from 0). Introduced a new "nowrap" argument. - #928: psutil.net_connections() and psutil.Process.connections() "laddr" and "raddr" are now named tuples. - #1015: swap_memory() now relies on /proc/meminfo instead of sysinfo() syscall so that it can be used in conjunction with PROCFS_PATH in order to retrieve memory info about Linux containers such as Docker and Heroku. - #1022: psutil.users() provides a new "pid" field. - #1025: process_iter() accepts two new parameters in order to invoke Process.as_dict(): "attrs" and "ad_value". With this you can iterate over all processes in one shot without needing to catch NoSuchProcess and do list/dict comprehensions. - #1040: implemented full unicode support. - #1051: disk_usage() on Python 3 is now able to accept bytes. - #1058: test suite now enables all warnings by default. - #1060: source distribution is dynamically generated so that it only includes relevant files. - #1079: [FreeBSD] net_connections()'s fd number is now being set for real (instead of -1). (patch by Gleb Smirnoff) - #1091: [SunOS] implemented Process.environ(). (patch by Oleksii Shevchuk) **Bug fixes** - #989: [Windows] boot_time() may return a negative value. - #1007: [Windows] boot_time() can have a 1 sec fluctuation between calls; the value of the first call is now cached so that boot_time() always returns the same value if fluctuation is <= 1 second. - #1013: [FreeBSD] psutil.net_connections() may return incorrect PID. (patch by Gleb Smirnoff) - #1014: [Linux] Process class can mask legitimate ENOENT exceptions as NoSuchProcess. - #1016: disk_io_counters() raises RuntimeError on a system with no disks. - #1017: net_io_counters() raises RuntimeError on a system with no network cards installed. - #1021: [Linux] open_files() may erroneously raise NoSuchProcess instead of skipping a file which gets deleted while open files are retrieved. - #1029: [OSX, FreeBSD] Process.connections('unix') on Python 3 doesn't properly handle unicode paths and may raise UnicodeDecodeError. - #1033: [OSX, FreeBSD] memory leak for net_connections() and Process.connections() when retrieving UNIX sockets (kind='unix'). - #1040: fixed many unicode related issues such as UnicodeDecodeError on Python 3 + UNIX and invalid encoded data on Windows. - #1042: [FreeBSD] psutil won't compile on FreeBSD 12. - #1044: [OSX] different Process methods incorrectly raise AccessDenied for zombie processes. - #1046: [Windows] disk_partitions() on Windows overrides user's SetErrorMode. - #1047: [Windows] Process username(): memory leak in case exception is thrown. - #1048: [Windows] users()'s host field report an invalid IP address. - #1050: [Windows] Process.memory_maps memory() leaks memory. - #1055: cpu_count() is no longer cached; this is useful on systems such as Linux where CPUs can be disabled at runtime. This also reflects on Process.cpu_percent() which no longer uses the cache. - #1058: fixed Python warnings. - #1062: disk_io_counters() and net_io_counters() raise TypeError if no disks or NICs are installed on the system. - #1063: [NetBSD] net_connections() may list incorrect sockets. - #1064: [NetBSD] swap_memory() may segfault in case of error. - #1065: [OpenBSD] Process.cmdline() may raise SystemError. - #1067: [NetBSD] Process.cmdline() leaks memory if process has terminated. - #1069: [FreeBSD] Process.cpu_num() may return 255 for certain kernel processes. - #1071: [Linux] cpu_freq() may raise IOError on old RedHat distros. - #1074: [FreeBSD] sensors_battery() raises OSError in case of no battery. - #1075: [Windows] net_if_addrs(): inet_ntop() return value is not checked. - #1077: [SunOS] net_if_addrs() shows garbage addresses on SunOS 5.10. (patch by Oleksii Shevchuk) - #1077: [SunOS] net_connections() does not work on SunOS 5.10. (patch by Oleksii Shevchuk) - #1079: [FreeBSD] net_connections() didn't list locally connected sockets. (patch by Gleb Smirnoff) - #1085: cpu_count() return value is now checked and forced to None if <= 1. - #1087: Process.cpu_percent() guard against cpu_count() returning None and assumes 1 instead. - #1093: [SunOS] memory_maps() shows wrong 64 bit addresses. - #1094: [Windows] psutil.pid_exists() may lie. Also, all process APIs relying on OpenProcess Windows API now check whether the PID is actually running. - #1098: [Windows] Process.wait() may erroneously return sooner, when the PID is still alive. - #1099: [Windows] Process.terminate() may raise AccessDenied even if the process already died. - #1101: [Linux] sensors_temperatures() may raise ENODEV. **Porting notes** - #1039: returned types consolidation: - Windows / Process.cpu_times(): fields #3 and #4 were int instead of float - Linux / FreeBSD: connections('unix'): raddr is now set to "" instead of None - OpenBSD: connections('unix'): laddr and raddr are now set to "" instead of None - #1040: all strings are encoded by using OS fs encoding. - #1040: the following Windows APIs on Python 2 now return a string instead of unicode: - Process.memory_maps().path - WindowsService.bin_path() - WindowsService.description() - WindowsService.display_name() - WindowsService.username() *2017-04-10* Links ===== - Home page: https://github.com/giampaolo/psutil - Download: https://pypi.python.org/pypi/psutil - Documentation: http://pythonhosted.org/psutil - What's new: https://github.com/giampaolo/psutil/blob/master/HISTORY.rst -- Giampaolo - http://grodola.blogspot.com

[ANN} pyDotNet 0.9.2 released
by Jonathan Shore 02 Sep '17

02 Sep '17

I’ve published a package on PyPi called ‘pyDotNet’. pyDotNet allows Python to access .NET libraries. From Python one can: * create .NET objects * call member functions * call class functions (i.e. static members) * access and set properties * access indexing members .NET objects are provided as python objects via proxy, so can be interacted within the python object idiom. The package will run with mono on OS X or Linux and on windows with the Microsoft .NET VM. Find the source and description of the package on: https://github.com/tr8dr/.Net-Bridge/tree/master/src/Python/pyDotNet <https://github.com/tr8dr/.Net-Bridge/tree/master/src/Python/pyDotNet> And the PyPi link as: https://pypi.python.org/pypi/pydotnet <https://pypi.python.org/pypi/pydotnet> The package is stable, as has been in use for some years, but only now packaged up for public use on PyPi. Feel free to contact with questions or suggestions on GitHub or by email. Regards -- Jonathan Shore
