devpi-{server-2.1.2,web-2.2.1}: bugfixes, streamlined web templates

by holger krekel

devpi-server-2.1.2 and devpi-web-2.2.1 bring a host of fixes to the private pypi server system. You can upgrade without migrating your data if you run already with devpi-server-2.1.X. Find docs as usual at: http://doc.devpi.net Many thanks to Florian Schulze who did most of the changes in devpi-web. Have fun, holger krekel, merlinux GmbH devpi-server-2.1.2 ------------------ - fix issue172: avoid traceback when user/index/name/version is accessed. - fix issue170: ensure that we parse the prospective pip-6.0 user agent string properly so that using the username/index url works with pip. Thanks Donald Stufft and Florian Schulze. - fix issue158: redirect to normalized projectname for all GET views. - fix issue169: change /+status to expose "event_serial" as "the last event serial that was processed". document "serial" and "event-serial" and also refine internals wrt to "event-serial" so that it means the "last serial for which events have been processed" devpi-web-2.2.1 --------------- - require devpi-server>=2.1.2 - fix issue175: use normalized name of projects, so redirects from unnormalized names works. NOTE that if you had issues with documentation uploads not appearing because of normalization issues ("-" or "_" appearing in the name for example) you need to re-upload the docs or do a full export/import cycle. - fix view when tox results can not be parsed. - version.pt: removed "code" tag around overwrite count. - macros.pt: added "footer" tag around the whole footer part. - version.pt: moved file type, python version and size info from their own columns into the file column. - version.pt: moved history column from before the tox results column to behind the tox results. - version.pt: removed "last modified" from history column - version.pt: removed timestamp from "replaced" action in history column - version.pt: add link to PyPI page if applicable. - fix project page view if there are downloads with filenames which can't be parsed as packages with version number - fix notfound-redirect when serving under an outside URL with a sub path

pytest-2.6.4: bugfix release

by holger krekel

Hi all, just pushed pytest-2.6.4 to pypi, a small bug fix release. pytest is a popular and mature Python testing tool with more than a 1100 tests against itself, passing on many different interpreters and platforms. This release is drop-in compatible to 2.5.2 and 2.6.X. See below for the changes and see docs at: http://pytest.org Thanks to all who contributed, among them: Bruno Oliveira Floris Bruynooghe Dinu Gherman Anatoly Bubenkoff best, holger krekel, merlinux GmbH 2.6.4 ---------- - Improve assertion failure reporting on iterables, by using ndiff and pprint. - removed outdated japanese docs from source tree. - docs for "pytest_addhooks" hook. Thanks Bruno Oliveira. - updated plugin index docs. Thanks Bruno Oliveira. - fix issue557: with "-k" we only allow the old style "-" for negation at the beginning of strings and even that is deprecated. Use "not" instead. This should allow to pick parametrized tests where "-" appeared in the parameter. - fix issue604: Escape % character in the assertion message. - fix issue620: add explanation in the --genscript target about what the binary blob means. Thanks Dinu Gherman. - fix issue614: fixed pastebin support.

ANN: eGenix pyOpenSSL Distribution 0.13.5

by eGenix Team: M.-A. Lemburg

________________________________________________________________________ ANNOUNCING eGenix.com pyOpenSSL Distribution Version 0.13.5 An easy-to-install and easy-to-use distribution of the pyOpenSSL Python interface for OpenSSL - available for Windows, Mac OS X and Unix platforms This announcement is also available on our web-site for online reading: http://www.egenix.com/company/news/eGenix-pyOpenSSL-Distribution-0.13.5.html ________________________________________________________________________ INTRODUCTION The eGenix.com pyOpenSSL Distribution includes everything you need to get started with SSL in Python. It comes with an easy-to-use installer that includes the most recent OpenSSL library versions in pre-compiled form, making your application independent of OS provided OpenSSL libraries: http://www.egenix.com/products/python/pyOpenSSL/ pyOpenSSL is an open-source Python add-on that allows writing SSL/TLS- aware network applications as well as certificate management tools: https://launchpad.net/pyopenssl/ OpenSSL is an open-source implementation of the SSL/TLS protocol: http://www.openssl.org/ ________________________________________________________________________ NEWS This new release of the eGenix.com pyOpenSSL Distribution updates the included OpenSSL version to the latest OpenSSL 1.0.1h version and adds a few more context options: New in OpenSSL -------------- * Updated included OpenSSL libraries from OpenSSL 1.0.1i to 1.0.1j. See https://www.openssl.org/news/secadv_20141015.txt for a complete list of changes. The following fixes are relevant for pyOpenSSL applications: - CVE-2014-3567: Memory leak in OpenSSL session ticket management. - OpenSSL has added support for TLS_FALLBACK_SCSV to allow applications to block the ability for a MITM attacker to force a protocol downgrade, e.g. to enable a POODLE (CVE-2014-3566) attack by forcing a downgrade to SSLv3. This is enabled automatically for servers. - CVE-2014-3568: OpenSSL configured with "no-ssl3" would still allow a complete SSL 3.0 handshake to run. New in pyOpenSSL ---------------- * Dropped zlib support from OpenSSL builds to more easily prevent the CRIME attack without having to use special SSL context options. * Disabled the SSLv2 support in OpenSSL builds. SSLv2 has long been broken and this simplifies writing secure servers/clients. * Updated the included CA root certificate bundles to Mozilla's 2014-08-26 update. * Improved cipher list in https_client.py example which prefers the newer AES128-GCM and elliptic curve DH over over ciphers. * Added new context flag MODE_SEND_FALLBACK_SCSV. Documented previously undocumented MODE_RELEASE_BUFFERS and removed non-existing MODE_NO_COMPRESSION from the documentation. * Added web installer package to the Python Package Index (PyPI) which simplifies installation. * In addition to the usual ways of installing eGenix pyOpenSSL, we have uploaded a web installer to PyPI, so that it is now also possible to use one of these installation methods on all supported platforms (Windows, Linux, Mac OS X): - easy_install egenix-pyopenssl via PyPI - pip install egenix-pyopenssl via PyPI - egg reference in zc.buildout via PyPI - running "python setup.py install" in the unzipped web installer archive directory The web installer will automatically detect the platform and choose the right binary download package for you. All downloads are verified before installation. * Resolved a problem with a pyOpenSSL test for certificate extensions: OpenSSL 1.0.1i+ wants a signature algorithm to be defined when loading PEM certificates. * Moved eGenix additions to pyOpenSSL to a new extras/ dir in the source distribution. * In previous releases, we also added the OpenSSL version number to the package version. Since this causes very long version numbers, we have dropped the OpenSSL version starting with 0.13.5 and will only increase the main version number from now on. In the future, we plan to switch to a new version scheme that is compatible with our normal version number scheme for products. pyOpenSSL / OpenSSL Binaries Included ------------------------------------- In addition to providing sources, we make binaries available that include both pyOpenSSL and the necessary OpenSSL libraries for all supported platforms: Windows x86 and x64, Linux x86 and x64, Mac OS X PPC, x86 and x64. We've also added egg-file distribution versions of our eGenix.com pyOpenSSL Distribution for Windows, Linux and Mac OS X to the available download options. These make setups using e.g. zc.buildout and other egg-file based installers a lot easier. ________________________________________________________________________ DOWNLOADS The download archives and instructions for installing the package can be found at: http://www.egenix.com/products/python/pyOpenSSL/ ________________________________________________________________________ UPGRADING Before installing this version of pyOpenSSL, please make sure that you uninstall any previously installed pyOpenSSL version. Otherwise, you could end up not using the included OpenSSL libs. _______________________________________________________________________ SUPPORT Commercial support for these packages is available from eGenix.com. Please see http://www.egenix.com/services/support/ for details about our support offerings. ________________________________________________________________________ MORE INFORMATION For more information about the eGenix pyOpenSSL Distribution, licensing and download instructions, please visit our web-site or write to sales(a)egenix.com.

Eliot 0.5.0: Structured Logging as Storytelling

by Itamar Turner-Trauring

Eliot provides a structured logging and tracing system for Python that generates log messages describing a forest of nested actions. Actions start and eventually finish, successfully or not. Log messages thus tell a story: what happened and what caused it. Eliot is released by ClusterHQ <https://docs.clusterhq.com>, the Data People for Docker™, and is available at https://pypi.python.org/pypi/eliot. Here's what your logs might look like before using Eliot: Going to validate http://example.com/index.html. Started download attempted. Download succeeded! Missing <title> element in "/html/body". Bad HTML entity in "/html/body/p[2]". 2 validation errors found! After switching to Eliot you'll get a tree of messages with both message contents and causal relationships encoded in a structured format: - {"action_type": "validate_page", "action_status": "started", "url": " http://example.com/index.html"} - {"action_type": "download", "action_status": "started"} - {"action_type": "download", "action_status": "succeeded"} - {"action_type": "validate_html", "action_status": "started"} - {"message_type": "validation_error", "error_type": "missing_title", "xpath": "/html/head"} - {"message_type": "validation_error", "error_type": "bad_entity", "xpath": "/html/body/p[2]"} - {"action_type": "validate_html", "action_status": "failed", "exception": "validator.ValidationFailed"} - {"action_type": "validate_page", "action_status": "failed", "exception": "validator.ValidationFailed"} What's New in 0.5.0: - Added support for Python 3.4. - Most public methods and functions now have underscore-based equivalents to the camel case versions, e.g. eliot.write_traceback and eliot.writeTraceback, for use in PEP 8 styled programs. Twisted-facing APIs and pyunit assertions do not provide these additional APIs, as camel-case is the native idiom. - eliot.to_file outputs log messages to a file. - Documented how to load Eliot logging into ElasticSearch via Logstash. - Documentation has been significantly reorganized.

py2exe 0.9.2.2 released

by Thomas Heller

py2exe version 0.9.2.2 released =============================== `py2exe` is a distutils extension which allows to build standalone Windows executable programs (32-bit and 64-bit) from Python scripts; Python 3.3 and later are supported. It can build console executables, windows (GUI) executables, windows services, and DLL/EXE COM servers. (For Python 2.3 - 2.7 the older version 0.6.9 is still available.) Changes in version 0.9.2.2: - Added support for six, cffi, pycparser, openssl. - The cmdline_style options for windows services ("py2exe", "pywin32", "custom") should work again. - Several bugfixes, better error messages. News for py2exe 0.9.2: - brand new implementation, written from scratch for Python 3 - py2exe now supports Python 3.3 and 3.4 - can be installed with 'pip' since py2exe is released in wheel format (in addition to a source package and bdist_wininst installers) - less warnings from the build process thanks to a hooks module which contains knowledge about some often used packages - easy start: executables can now be built with a simple command line script; no need to write a setup-script from scratch. In fact a commented setup-script can now be autogenerated - py2exe does now find Python modules even in zipped eggs Short manual and download at the Python cheeseshop (or simply install or upgrade it with 'pip install -U py2exe'): https://pypi.python.org/pypi/py2exe/0.9.2.2/ Enjoy, Thomas

PyPy3 2.4.0 released

by Philip Jenvey

================================================= PyPy3 2.4 - Snow White ================================================= We're pleased to announce PyPy3 2.4, which contains significant performance enhancements and bug fixes. You can download the PyPy3 2.4.0 release here: http://pypy.org/download.html PyPy3 Highlights ================ Issues reported with our previous release were fixed after reports from users on our new issue tracker at https://bitbucket.org/pypy/pypy/issues or on IRC at #pypy. Here is a summary of the user-facing PyPy3 specific changes: * Better Windows compatibility, e.g. the nt module functions _getfinalpathname & _getfileinformation are now supported (the former is required for the popular pathlib library for example) * Various fsencode PEP 383 related fixes to the posix module (readlink, uname, ttyname and ctermid) and improved locale handling * Switched default binary name os POSIX distributions to 'pypy3' (which symlinks to to 'pypy3.2') * Fixed a couple different crashes related to parsing Python 3 source code Further Highlights (shared w/ PyPy2) ==================================== Benchmarks improved after internal enhancements in string and bytearray handling, and a major rewrite of the GIL handling. This means that external calls are now a lot faster, especially the CFFI ones. It also means better performance in a lot of corner cases with handling strings or bytearrays. The main bugfix is handling of many socket objects in your program which in the long run used to "leak" memory. We fixed a memory leak in IO in the sandbox_ code We welcomed more than 12 new contributors, and conducted two Google Summer of Code projects, as well as other student projects not directly related to Summer of Code. * Reduced internal copying of bytearray operations * Tweak the internal structure of StringBuilder to speed up large string handling, which becomes advantageous on large programs at the cost of slightly slower small *benchmark* type programs. * Boost performance of thread-local variables in both unjitted and jitted code, this mostly affects errno handling on linux, which makes external calls faster. * Move to a mixed polling and mutex GIL model that make mutlithreaded jitted code run *much* faster * Optimize errno handling in linux (x86 and x86-64 only) * Remove ctypes pythonapi and ctypes.PyDLL, which never worked on PyPy * Classes in the ast module are now distinct from structures used by the compiler, which simplifies and speeds up translation of our source code to the PyPy binary interpreter * Win32 now links statically to zlib, expat, bzip, and openssl-1.0.1i. No more missing DLLs * Many issues were resolved_ since the 2.3.1 release in June .. _`whats-new`: http://doc.pypy.org/en/latest/whatsnew-2.4.0.html .. _resolved: https://bitbucket.org/pypy/pypy/issues?status=resolved .. _sandbox: http://doc.pypy.org/en/latest/sandbox.html We have further improvements on the way: rpython file handling, numpy linalg compatibility, as well as improved GC and many smaller improvements. Please try it out and let us know what you think. We especially welcome success stories, we know you are using PyPy, please tell us about it! Cheers The PyPy Team
