devpi-1.0: PyPI server and packaging/testing/release tool

by holger krekel

devpi-1.0: PyPI server and packaging/testing/release tool ========================================================= devpi-1.0 brings an improved PyPI caching and internal index server as well as a new abilities for tox-testing and staging your Python release packages. For a (long) list of changes, see the below CHANGELOG. Documentation got revamped and extended and now contains three quickstart scenarios. First the Quickstart tutorial for pypi-mirroring on your laptop:: http://doc.devpi.net/1.0/quickstart-pypimirror.html And if you want to manage your releases or implement staging as an individual or within an organisation:: http://doc.devpi.net/1.0/quickstart-releaseprocess.html If you want to permanently install devpi-server and potentially access it from many clients:: http://doc.devpi.net/1.0/quickstart-server.html More documentation and the beginning of an exhaustive user manual:: http://doc.devpi.net/latest/ Note that devpi-1.0 is not data-compatible to the previous 0.9.4 release: You need to start with a fresh devpi-1.0 installation and upload your packages again. Future releases of devpi should support data migration more directly. best and have fun, holger krekel Changelog 1.0 (-0.9.4) ---------------------------- devpi-server: - rename "--datadir" to "--serverdir" to better match the also picked up DEVPI_SERVERDIR environment variable. - fix a strange effect in that sometimes tools ask to receive a package url with a "#md5=..." arriving at the server side. We now strip that part out before trying to serve the file. - on startup don't create any initial indexes other than the "root/pypi" pypi caching mirror. - introduce ``--start``, ``--stop`` and ``--log`` commands for controling a background devpi-server run. (these commands previously were implemented with the devpi-client and the "server" sub command) - fix issue27: provide full list of pypi names in root/pypi's simple view (and simple pages from inheriting indices) - default to "eventlet" server when creating deployment with --gendeploy - fix issue25: return 403 Forbidden when trying to delete the root user. - fix name mangling issue for pypi-cache: "project_name*" is now matched correctly when a lookup for "project-name" happens. - fix issue22: don't bypass CDN by default, rather provide an "--bypass-cdn" option to do it (in case you have cache-invalidation troubles) - fix issue20 and fix issue23: normalize index specs internally ("/root/dev" -> "root/dev") and check if base indices exist. - add Jenkins build job triggering for running the tests for a package through tox. - inheritance cleanup: inherited versions for a project are now shadowed and not shown anymore with getreleaselinks() or in +simple pages if the "basename" is exactly shadowed. - fix issue16: enrich projectconfig json with a "+shadow" file which lists shadowed "versions" - initial wheel support: accept "whl" uploads and support caching of whl files from pypi.python.org - implemented internal push operation between devpi indexes - show "docs" link if documentation has been uploaded - pushing releases to pypi.python.org will now correctly report the filetype/pyversion in the metadata. - add setting of acl_upload for indexes. Only the owning user and acl_upload users may upload releases, files or documentation to an index. - add --passwd USER option for setting a user's password server-side - don't require email setting for creating users devpi-client: - removed ``server`` subcommand and options for controling background devpi-server processes to become options of ``devpi-server`` itself. - fix issue14: lookup "python" from PATH for upload/packaging activities instead of using "sys.executable" which comes from the interpreter executing the "devpi" script. This allows to alias "devpi" to come from a virtualenv which is separate from the one used to perform packaging. - fix issue35: "devpi index" cleanly errors out if no index is specified or in use. - remember authentication on a per-root basis and cleanup "devpi use" interactions. This makes switching between multiple devpi instances more seemless. - fix issue17: better reporting when "devpi use" does not operate on valid URL - test result upload and access: - "devpi test" invokes "tox --result-json ..." and uploads the test result log to devpi-server. - "devpi list [-f] PKG" shows test result information. - add "uploadtrigger_jenkins" configuration option through "devpi index". - fix issue19: devpi use now memorizes --venv setting properly. Thanks Laurent. - fix issue16: show files from shadowed versions - initial wheel support: "devpi upload --format=bdist_wheel" now uploads a wheel format file to the index. (XXX "devpi install" will trigger pip commands with option "--use-wheels".) - fix issue15: docs will now be built via "setup.py build_sphinx" using a internal build dir so that the upload succeeds if conf.py would otherwise specify a non-standard location. - implement and refine "devpi push" command. It now accepts two forms "user/name" for specifying an internal devpi index and "pypi:REPONAME" for specifying a repository which must be defined in a .pypirc file. - remove spurious pdb.set_trace() in devpi install command when no pip can be found. - show and allow to set "acl_upload" for uploading priviliges - add longer descriptions to each sub command, shown with "devpi COMMAND -h". - removed pytestplugin support for now (pytest reporting directly to devpi-server)

tox-1.6: support for install_command, develop, py25

by holger krekel

tox-1.6: support for install_command, develop, py25 ============================================================= Welcome to a new release of tox, the virtualenv-based test automation manager. This release brings some new major features: - installer_command: you can customize the command user for installing packages and dependencies. Thanks Carl Meyer. - usedevelop: you can use "develop" mode ("pip install -e") either by configuring it in your tox.ini or through the new "--develop" option. Thank Monty Tailor. - python2.5: tox ships internally virtualenv-1.9.1 and can thus run tests create virtualenvs and run tests against python2.5 even if you have a newer virtualenv version installed. While tox-1.6 should otherwise be compatible to tox-1.5, the new $HOME-isolation ($HOME is set to a temporary directory when installing packages) might trigger problems if your tests relied on $HOME configuration files -- which they shouldn't if you want to repeatability. If that causes problems, please file an issue. Docs and more information at: http://testrun.org/tox/latest/ have fun, holger krekel 1.6 Changelog -------------- - fix issue35: add new EXPERIMENTAL "install_command" testenv-option to configure the installation command with options for dep/pkg install. Thanks Carl Meyer for the PR and docs. - fix issue91: python2.5 support by vendoring the virtualenv-1.9.1 script and forcing pip<1.4. Also the default [py25] environment modifies the default installer_command (new config option) to use pip without the "--pre" option which was introduced with pip-1.4 and is now required if you want to install non-stable releases. (tox defaults to install with "--pre" everywhere). - during installation of dependencies HOME is now set to a pseudo location ({envtmpdir}/pseudo-home). If an index url was specified a .pydistutils.cfg file will be written with an index_url setting so that packages defining ``setup_requires`` dependencies will not silently use your HOME-directory settings or https://pypi.python.org. - fix issue1: empty setup files are properly detected, thanks Anthon van der Neuth - remove toxbootstrap.py for now because it is broken. - fix issue109 and fix issue111: multiple "-e" options are now combined (previously the last one would win). Thanks Anthon van der Neut. - add --result-json option to write out detailed per-venv information into a json report file to be used by upstream tools. - add new config options ``usedevelop`` and ``skipsdist`` as well as a command line option ``--develop`` to install the package-under-test in develop mode. thanks Monty Tailor for the PR. - always unset PYTHONDONTWRITEBYTE because newer setuptools doesn't like it - if a HOMEDIR cannot be determined, use the toxinidir. - refactor interpreter information detection to live in new tox/interpreters.py file, tests in tests/test_interpreters.py.

Eventlet is going to drop Python 2.5 support in favour of Python 3.3+

by Sergey Shepelev

If you use Eventlet on Python 2.5 - bad news. Sample script to check: # relies on virtualenv activated or eventlet installed globally if python --version 2>&1 |fgrep -q 'Python 2.5' ; then if pip freeze |fgrep -q eventlet ; then echo 'bad news, read on' else echo ok fi else echo ok fi As discussed here https://github.com/eventlet/eventlet/issues/6 we're going to drop Python 2.5 support in some near future. Previous releases are still available for download in PyPi. I encourage everybody to repost this message to your friends and colleagues. If this change touches anybody, please, respond: - by email eventletdev(a)lists.secondlife.com - in Google+ https://plus.google.com/109869205442495270563/posts/GveGYMzubsp - in Github issue https://github.com/eventlet/eventlet/issues/6

Astroid 1.0 released

by Sylvain Thénault

Astroid_ is the new name of former logilab-astng library. It's an AST library, used as the basis of Pylint_ and including Python 2.5 -> 3.3 compatible tree representation, statical type inference and other features useful for advanced Python code analysis, such as an API to provide extra information when statistical inference can't overcome Python dynamic nature (see the `pylint-brain`_ project for instance). It has been renamed and hosted to bitbucket to make clear that this is not a Logilab dedicated project but a community project that could benefit to any people manipulating Python code (statistical analysis tools, IDE, browser, etc). Documentation is a bit rough but should quickly improve. Also a dedicated web-site is now online, visit www.astroid.org (or https://bitbucket.org/logilab/astroid for development). You may download and install it from Pypi or from `Logilab's debian repositories`_. .. _Pylint: http://www.pylint.org .. _`Logilab's debian repositories`: http://www.logilab.org/bookmark/4621/follow .. _Astroid: http://www.astroid.org .. _`pylint-brain`: https://bitbucket.org/logilab/pylint-brain Enjoy! -- Sylvain Thénault, LOGILAB, Paris (01.45.32.03.12) - Toulouse (05.62.17.16.42) Formations Python, Debian, Méth.
