ANN: Trio v0.2.0 released
by Nathaniel Smith Dec. 7, 2017

Dec. 7, 2017

Hi all, I'm proud to announce the release of Trio v0.2.0. Trio is a new async concurrency library for Python that's obsessed with usability and correctness -- we want to make it easy to get things right. This is the second public release, and it contains major new features and bugfixes from 14 contributors. You can read the full release notes here: https://trio.readthedocs.io/en/latest/history.html#trio-0-2-0-2017-12-06 Some things I'm particularly excited about are: - Comprehensive support for async file I/O - The new 'nursery.start' method for clean startup of complex task trees - The new high-level networking API -- this is roughly the same level of abstraction as twisted/asyncio's protocols/transports. Includes luxuries like happy eyeballs for most robust client connections, and server helpers that integrate with nursery.start. - Complete support for using SSL/TLS encryption over arbitrary transports. You can even do SSL-over-SSL, which is useful for HTTPS proxies and AFAIK not supported by any other Python library. - Task-local storage. - Our new contributing guide: https://trio.readthedocs.io/en/latest/contributing.html To get started with Trio, the best place to start is our tutorial: https://trio.readthedocs.io/en/latest/tutorial.html It doesn't assume any prior familiarity with concurrency or async/await. Share and enjoy, -n -- Nathaniel J. Smith -- https://vorpus.org

ANN: psutil 5.4.2 released
by Giampaolo Rodola' Dec. 7, 2017

Dec. 7, 2017

Hello all, I'm glad to announce the release of psutil 5.4.2: 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, OSX, Sun Solaris, FreeBSD, OpenBSD, NetBSD and AIX, both 32-bit and 64-bit architectures, with Python versions from 2.6 to 3.6. PyPy is also known to work. What's new ========== *2017-12-07* **Enhancements** - #1173: introduced PSUTIL_DEBUG environment variable which can be set in order to print useful debug messages on stderr (useful in case of nasty errors). - #1177: added support for sensors_battery() on OSX. (patch by Arnon Yaari) - #1183: Process.children() is 2x faster on UNIX and 2.4x faster on Linux. - #1188: deprecated method Process.memory_info_ex() now warns by using FutureWarning instead of DeprecationWarning. **Bug fixes** - #1152: [Windows] disk_io_counters() may return an empty dict. - #1169: [Linux] users() "hostname" returns username instead. (patch by janderbrain) - #1172: [Windows] `make test` does not work. - #1179: [Linux] Process.cmdline() is now able to splits cmdline args for misbehaving processes which overwrite /proc/pid/cmdline and use spaces instead of null bytes as args separator. - #1181: [OSX] Process.memory_maps() may raise ENOENT. - #1187: [OSX] pids() does not return PID 0 on recent OSX versions. Links ===== - Home page: https://github.com/giampaolo/psutil - Download: https://pypi.python.org/pypi/psutil - Documentation: http://psutil.readthedocs.io - What's new: https://github.com/giampaolo/psutil/blob/master/HISTORY.rst -- Giampaolo - http://grodola.blogspot.com

Announcing importlib_resources 0.1

--Apple-Mail=_0B26B532-B293-4D6A-B887-30015D809C82 Content-Transfer-Encoding: quoted-printable Content-Type: text/plain; charset=utf-8 Brett and I have been working on a little skunkworks project for a few = weeks, and it=E2=80=99s now time to announce the first release. We=E2=80=99= re calling it importlib_resources and its intent is to replace the = =E2=80=9CBasic Resource Access=E2=80=9D APIs of pkg_resources with more = efficient implementations based directly on importlib. importlib_resources 0.1 provides support for Python 2.7, and 3.4-3.7. = It defines an ABC that loaders can implement to provide direct access to = resources inside packages. importlib_resources has fallbacks for file = system and zip file loaders, so it should work out of the box in most of = the places that pkg_resources is currently used. We even have a = migration guide for folks who want to drop pkg_resources altogether and = adopt importlib_resources. importlib_resources explicitly does not = support pkg_resources features like entry points, working sets, etc. = Still, we think the APIs provided will be good enough for most current = use cases. http://importlib-resources.readthedocs.io/ We are calling it =E2=80=9Cimportlib_resources=E2=80=9D because we = intend to port this into Python 3.7 under a new importlib.resources = subpackage, so starting with Python 3.7, you will get this for free. = The API is going to officially be provisional, but I=E2=80=99ve already = done an experimental port of at least one big application (I=E2=80=99ll = let you guess which one :) and it=E2=80=99s fairly straightforward, if = not completely mechanical unfortunately. Take a look at the migration = guide for details: http://importlib-resources.readthedocs.io/en/latest/migration.html We also intend to include the ABC in Python 3.7: http://importlib-resources.readthedocs.io/en/latest/abc.html You can of course `pip install importlib_resources`. We=E2=80=99re hosting the project on GitLab, and welcome feedback, bug = fixes, improvements, etc! * Project home: https://gitlab.com/python-devs/importlib_resources * Report bugs at: = https://gitlab.com/python-devs/importlib_resources/issues * Code hosting: https://gitlab.com/python-devs/importlib_resources.git * Documentation: http://importlib_resources.readthedocs.io/ Cheers. -Barry and Brett --Apple-Mail=_0B26B532-B293-4D6A-B887-30015D809C82 Content-Transfer-Encoding: 7bit Content-Disposition: attachment; filename=signature.asc Content-Type: application/pgp-signature; name=signature.asc Content-Description: Message signed with OpenPGP -----BEGIN PGP SIGNATURE----- iQIzBAEBCAAdFiEEhBcVftvnPZ6sHlObEm61Y6dLBr8FAlopftcACgkQEm61Y6dL Br8PRw//YC5f2FPNftR/GPNgt/wMa63sSwRgdxORMoUi7iip9vja4+HagikzLD94 zcUSu7XmXdgMULqisZ8xE0vsSiBae79sOHidN142c9YZLuom6jqDX0RILYoxFw44 xdcy/CHQGV4pNG81s1G9g3iNTaiYh15zJg8fh59R5daxZIBopNTAm3Kugeq9K2Xf qferhW5eQ0SgmyqLlDOcF8YgkH8F45b7CIa8p23amy4kVP1u305/Im/sVYTa5Bnn mb9VqDb/s1Ii0OghWoTEeVD070Fx4b503rr8AjpqUzixwgLssJDn3rcLrGE3sBki 32EbeZ8gM+NZQAmzKCV9cfPbDPWxLMn0TTdobRWxg1QarU0qzZsw8F5m20t9SE0L jBR2J1MdHdesuFEC4aNu3OoeTHH8whmVE/jcUYujdZa3RGX4/L6AmyNzYnwL9Qic kylLgDAnR5wNSoXFarTkgnt9/n7nQer8cK34c3duKnw+85INyWVPKicKf4qp8Oc9 K3K3DzWFnhrE0OTiZrO/UWwEL/GGRkVI1mSFx04i4i90hMuZXbHBGa2S63TZD6Xt Cxw0DdU5eT5sA+UoenJ0/a4S5jNvak858vX7NkAlXVr5npiha7teFiv4XWTNQHs5 Gt3BgQjQ1+v0ldF1Ujg/T+o3Z6eQFd3YdSku9Tgv7glcvf0UbNg= =YMqE -----END PGP SIGNATURE----- --Apple-Mail=_0B26B532-B293-4D6A-B887-30015D809C82--

Announcing the immediate availability of Python 3.6.4 release candidate 1 and of Python 3.7.0 alpha 3! Python 3.6.4rc1 is the first release candidate for Python 3.6.4, the next maintenance release of Python 3.6. While 3.6.4rc1 is a preview release and, thus, not intended for production environments, we encourage you to explore it and provide feedback via the Python bug tracker (https://bugs.python.org). 3.6.4 is planned for final release on 2017-12-18 with the next maintenance release expected to follow in about 3 months. You can find Python 3.6.4rc1 and more information here: https://www.python.org/downloads/release/python-364rc1/ Python 3.7.0a3 is the third of four planned alpha releases of Python 3.7, the next feature release of Python. During the alpha phase, Python 3.7 remains under heavy development: additional features will be added and existing features may be modified or deleted. Please keep in mind that this is a preview release and its use is not recommended for production environments. The next preview release, 3.7.0a4, is planned for 2018-01-08. You can find Python 3.7.0a3 and more information here: https://www.python.org/downloads/release/python-370a3/ -- Ned Deily nad(a)python.org -- []
