manypex 1.3.2.post2

ManyPEX=======.. image:: https://travis-ci.org/parsely/manypex.svg?branch=master :target: https://travis-ci.org/parsely/manypexManyPEX is a fork of the PEX project that adds support for manylinux wheels.We have `a PR <https://github.com/pantsbuild/pex/pull/316>`_ open to get thisfunctionality into PEX, but it has been open since late 2016 with no signs ofprogress. As we (and many other users) needed this feature, we decided to forkfor now.pex is a library for generating .pex (Python EXecutable) files which areexecutable Python environments in the spirit of `virtualenvs <http://virtualenv.org>`_.pex is an expansion upon the ideas outlined in`PEP 441 <http://legacy.python.org/dev/peps/pep-0441/>`_and makes the deployment of Python applications as simple as ``cp``. pex files may eveninclude multiple platform-specific Python distributions, meaning that a single pex filecan be portable across Linux and OS X.pex files can be built using the ``pex`` tool. Build systems such as `Pants<http://pantsbuild.org/>`_, `Buck <http://facebook.github.io/buck/>`_, and `{py}gradle <https://github.com/linkedin/pygradle>`_ alsosupport building .pex files directly.Still unsure about what pex does or how it works? Watch this quick lightningtalk: `WTF is PEX? <http://www.youtube.com/watch?v=NmpnGhRwsu0>`_.pex is licensed under the Apache2 license.Installation============To install pex, simply.. code-block:: bash pipinstallpexYoucanalsobuildpexinagitcloneusingtox:..code−block::bash tox -e py27-package cpdist/pex /binThisbuildsapexbinaryin‘‘dist/pex‘‘thatcanbecopiedontoyour‘‘PATH``.The advantage to this approach is that it keeps your Python environment as empty aspossible and is more in-line with what pex does philosophically.Simple Examples===============Launch an interpreter with ``requests``, ``flask`` and ``psutil`` in the environment:.. code-block:: bash pexrequestsflask′psutil>2,<3′Orinsteadfreezeyourcurrentvirtualenvviarequirements.txtandexecuteitanywhere:..code−block::bash pex -r <(pip freeze) -o my_virtualenv.pex deactivate ./my_virtualenv.pexRun webserver.py in an environment containing ``flask`` as a quick way to experiment:.. code-block:: bash pexflask−−webserver.pyLaunchSphinxinanephemeralpexenvironmentusingtheSphinxentrypoint‘‘sphinx:main‘‘:..code−block::bash pex sphinx -e sphinx:main -- --helpBuild a standalone pex binary into ``pex.pex`` using the ``pex`` console_scripts entry point:.. code-block:: bash pexpex−cpex−opex.pexYoucanalsobuildpexfilesthatuseaspecificinterpretertype:..code−block::bash pex pex -c pex --python=pypy -o pypy-pex.pexMost pex options compose well with one another, so the above commands can bemixed and matched. For a full list of options, just type ``pex --help``.Integrating pex into your workflow==================================If you use tox (and you should!), a simple way to integrate pex into yourworkflow is to add a packaging test environment to your ``tox.ini``:.. code-block:: ini [testenv:package] deps = pex commands = pex . -o dist/app.pexThen ``tox -e package`` will produce a relocateable copy of your applicationthat you can copy to staging or production environments.Documentation=============More documentation about pex, building .pex files, and how .pex files workis available at https://pex.readthedocs.io.Development===========pex uses `tox <https://testrun.org/tox/en/latest/>`_ for test and development automation. To runthe test suite, just invoke tox:.. code-block:: bash toxIfyoudon′thavetox,youcangenerateapexoftox:..code−block:: pex tox -c tox -o ~/bin/toxContributing============To contribute, follow these instructions: http://pantsbuild.org/howto_contribute.htmlRelease Notes=============1.3.2.post2-----* Fix a couple typos in README and setup.py1.3.2.post1-----* First release of manypex fork.

See the notes `here <https://github.com/pantsbuild/pex/blob/master/docs/buildingpex.rst#tailoring-pex-execution-at-build-time>`_. `#128 <https://github.com/pantsbuild/pex/pull/128>`_.* Bug fix: PEX_PROFILE_FILENAME and PEX_PROFILE_SORT were not respected. `#154 <https://github.com/pantsbuild/pex/issues/154>`_.* Adds the ``bdist_pex`` command to setuptools. `#99 <https://github.com/pantsbuild/pex/issues/99>`_.* Bug fix: We did not normalize package names in ``ResolvableSet``, so it was possible to depend on ``sphinx`` and ``Sphinx-1.4a0.tar.gz`` and get two versions build and included into the pex. `#147 <https://github.com/pantsbuild/pex/issues/147>`_.* Adds a pex-identifying User-Agent. `#101 <https://github.com/pantsbuild/pex/issues/101>`_.1.0.3-----* Bug fix: Accommodate OSX ``Python`` python binaries. Previously the OSX python distributions shipped with OSX, XCode and available via https://www.python.org/downloads/ could fail to be detected using the ``PythonInterpreter`` class. Fixes `#144 <https://github.com/pantsbuild/pex/issues/144>`_.* Bug fix: PEX_SCRIPT failed when the script was from a not-zip-safe egg. Original PR `#139 <https://github.com/pantsbuild/pex/pull/139>`_.* Bug fix: ``sys.exit`` called without arguments would cause `None` to be printed on stderr since pex 1.0.1. `#143 <https://github.com/pantsbuild/pex/pull/143>`_.1.0.2-----* Bug fix: PEX-INFO values were overridden by environment ``Variables`` with default values that were not explicitly set in the environment. Fixes `#135 <https://github.com/pantsbuild/pex/issues/135>`_.* Bug fix: Since `69649c1 <https://github.com/pantsbuild/pex/commit/69649c1>`_ we have been unpatching the side-effects of ``sys.modules`` after ``PEX.execute``. This takes all modules imported during the PEX lifecycle and sets all their attributes to ``None``. Unfortunately, ``sys.excepthook``, ``atexit`` and ``__del__`` may still try to operate using these tainted modules, causing exceptions on interpreter teardown. This reverts just the ``sys`` unpatching so that the abovementioned teardown hooks behave more predictably. Fixes `#141 <https://github.com/pantsbuild/pex/issues/141>`_.1.0.1-----* Allow PEXBuilder to optionally copy files into the PEX environment instead of hard-linking them.* Allow PEXBuilder to optionally skip precompilation of .py files into .pyc files.* Bug fix: PEXBuilder did not respect the target interpreter when compiling source to bytecode. Fixes `#127 <https://github.com/pantsbuild/pex/issues/127>`_.* Bug fix: Fix complex resolutions when using a cache. Fixes: `#120 <https://github.com/pantsbuild/pex/issues/120>`_.1.0.0-----The 1.0.0 release of pex introduces a few breaking changes: ``pex -r`` now takes requirements.txt filesinstead of requirement specs, ``pex -s`` has now been removed since source specs are accepted as arguments,and ``pex -p`` has been removed in favor of its alias ``pex -o``.The pex *command line interface* now adheres to semver insofar as backwards incompatible CLIchanges will invoke a major version change. Any backwards incompatible changes to the PEXenvironment variable semantics will also result in a major version change. The pex *API* adheresto semver insofar as backwards incompatible API changes will invoke minor version changes.For users of the PEX API, it is recommended to add minor version ranges, e.g. ``pex>=1.0,<1.1``.For users of the PEX CLI, major version ranges such as ``pex>=1,<2`` should be sufficient.* BREAKING CHANGE: Removes the ``-s`` option in favor of specifying directories directly as arguments to the pex command line.* BREAKING CHANGE: ``pex -r`` now takes requirements.txt filenames and *not* requirement specs. Requirement specs are now passed as arguments to the pex tool. Use ``--`` to escape command line arguments passed to interpreters spawned by pex. Implements `#5 <https://github.com/pantsbuild/pex/issues/5>`_.* Adds a number of flag aliases to be more compatible with pip command lines: ``--no-index``, ``-f``, ``--find-links``, ``--index-url``, ``--no-use-wheel``. Removes ``-p`` in favor of ``-o`` exclusively.* Adds ``--python-shebang`` option to the pex tool in order to set the ``#!`` shebang to an exact path. `#53 <https://github.com/pantsbuild/pex/issues/53>`_.* Adds support for ``PEX_PYTHON`` environment variable which will cause the pex file to reinvoke itself using the interpreter specified, e.g. ``PEX_PYTHON=python3.4`` or ``PEX_PYTHON=/exact/path/to/interpreter``. `#27 <https://github.com/pantsbuild/pex/issues/27>`_.* Adds support for ``PEX_PATH`` environment variable which allows merging of PEX environments at runtime. This can be used to inject plugins or entry_points or modules from one PEX into another without explicitly building them together. `#30 <https://github.com/pantsbuild/pex/issues/30>`_.* Consolidates documentation of ``PEX_`` environment variables and adds the ``--help-variables`` option to the pex client. Partially addresses `#13 <https://github.com/pantsbuild/pex/issues/13>`_.* Adds helper method to dump a package subdirectory onto disk from within a zipped PEX file. This can be useful for applications that know they're running within a PEX and would prefer some static assets dumped to disk instead of running as an unzipped PEX file. `#12 <https://github.com/pantsbuild/pex/pull/12>`_.* Now supports extras for static URLs and installable directories. `#65 <https://github.com/pantsbuild/pex/issues/65>`_.* Adds ``-m`` and ``--entry-point`` alias to the existing ``-e`` option for entry points in the pex tool to evoke the similarity to ``python -m``.* Adds console script support via ``-c/--script/--console-script`` and ``PEX_SCRIPT``. This allows you to reference the named entry point instead of the exact ``module:name`` pair. Also supports scripts defined in the ``scripts`` section of setup.py. `#59 <https://github.com/pantsbuild/pex/issues/59>`_.* Adds more debugging information when encountering unresolvable requirements. `#79 <https://github.com/pantsbuild/pex/issues/79>`_.* Bug fix: ``PEX_COVERAGE`` and ``PEX_PROFILE`` did not function correctly when SystemExit was raised. Fixes `#81 <https://github.com/pantsbuild/pex/issues/81>`_.* Bug fix: Fixes caching in the PEX tool since we don't cache the source distributions of installable directories. `#24 <https://github.com/pantsbuild/pex/issues/24>`_.0.9.0-----This is the last release before the 1.0.0 development branch is started.* Change the setuptools range to >=2.2,<16 by handling EntryPoint changes as well as being flexible on whether ``pkg_resources`` is a package or a module. Fixes `#55 <https://github.com/pantsbuild/pex/issues/55>`_ and `#34 <https://github.com/pantsbuild/pex/issues/34>`_.* Adds option groups to the pex tool to make the help output slightly more readable.* Bug fix: Make ``pip install pex`` work better by removing ``extras_requires`` on the ``console_script`` entry point. Fixes `#48 <https://github.com/pantsbuild/pex/issues/48>`_* New feature: Adds an interpreter cache to the ``pex`` tool. If the user does not explicitly disable the wheel feature and attempts to build a pex with wheels but does not have the wheel package installed, pex will download it in order to make the feature work. Implements `#47 <https://github.com/pantsbuild/pex/issues/47>`_ in order to fix `#48 <https://github.com/pantsbuild/pex/issues/48>`_0.8.6-----* Bug fix: Honor installed sys.excepthook in pex teardown. `RB #1733 <https://rbcommons.com/s/twitter/r/1733>`_* Bug fix: ``UrllibContext`` used ``replace`` as a keyword argument for ``bytes.decode`` but this only works on Python 3. `Pull Request #46 <https://github.com/pantsbuild/pex/pull/46>`_0.8.5-----* Bug fix: Fixup string formatting in pex/bin/pex.py to support Python 2.6 `Pull Request #40 <https://github.com/pantsbuild/pex/pull/40>`_0.8.4-----* Performance improvement: Speed up the best-case scenario of dependency resolution. `RB #1685 <https://rbcommons.com/s/twitter/r/1685>`_* Bug fix: Change from ``uuid4().get_hex()`` to ``uuid4().hex`` to maintain Python3 compatibility of pex.common. `Pull Request #39 <https://github.com/pantsbuild/pex/pull/39>`_* Bug fix: Actually cache the results of translation. Previously bdist translations would be created in a temporary directory even if a cache location was specified. `RB #1666 <https://rbcommons.com/s/twitter/r/1666>`_* Bug fix: Support all potential abi tag permutations when determining platform compatibility. `Pull Request #33 <https://github.com/pantsbuild/pex/pull/33>`_0.8.3-----* Performance improvement: Don't always write packages to disk if they've already been cached. This can significantly speed up launching PEX files with a large number of non-zip-safe dependencies. `RB #1642 <https://rbcommons.com/s/twitter/r/1642>`_0.8.2-----* Bug fix: Allow pex 0.8.x to parse pex files produced by earlier versions of pex and twitter.common.python.* Pin pex to setuptools prior to 9.x until we have a chance to make changes related to PEP440 and the change of pkg_resources.py to a package.0.8.1-----* Bug fix: Fix issue where it'd be possible to ``os.path.getmtime`` on a remote ``Link`` object `Issue #29 <https://github.com/pantsbuild/pex/issues/29>`_0.8.0-----* *API change*: Decouple translation from package iteration. This removes the Obtainer construct entirely, which likely means if you're using PEX as a library, you will need to change your code if you were doing anything nontrivial. This adds a couple new options to ``resolve`` but simplifies the story around how to cache packages. `RB #785 <https://rbcommons.com/s/twitter/r/785/>`_* Refactor http handling in pex to allow for alternate http implementations. Adds support for `requests <https://github.com/kennethreitz/requests>`_, improving both performance and security.

Under certain circumstances, namespace packages in site-packages could conflict with packages within a PEX, causing them to fail importing. `RB #1378 <https://rbcommons.com/s/twitter/r/1378/>`_* Bug fix: Replace uses of ``os.unsetenv(...)`` with ``del os.environ[...]`` `Pull Request #11 <https://github.com/pantsbuild/pex/pull/11>`_* Bug fix: Scrub sys.path and sys.modules based upon both supplied path and realpath of files and directories. Newer versions of virtualenv on Linux symlink site-packages which caused those packages to not be removed from sys.path correctly. `Issue #21 <https://github.com/pantsbuild/pex/issues/21>`_* Bug fix: The pex -s option was not correctly pulling in transitive dependencies. `Issue #22 <https://github.com/pantsbuild/pex/issues/22>`_* Bug fix: Adds ``content`` method to HTTP contexts that does HTML content decoding, fixing an encoding issue only experienced when using Python 3. `Issue #10 <https://github.com/pantsbuild/pex/issues/10>`_0.7.0-----* Rename ``twitter.common.python`` to ``pex`` and split out from the `twitter/commons <http://github.com/twitter/commons>`_ repo.0.6.0-----* Change the interpretation of ``-i`` (and of PyPIFetcher's pypi_base) to match pip's ``-i``. This is useful for compatibility with devpi.0.5.10------* Ensures that .egg/.whl distributions on disk have their mtime updated even though we no longer overwrite them. This gives them a new time lease against their ttl. Without this change, once a distribution aged past the ttl it would never be used again, and builds would re-create the same distributions in tmpdirs over and over again.0.5.9-----* Fixes an issue where SourceTranslator would overwrite .egg/.whl distributions already on disk. Instead it should always check to see if a copy already exists and reuse if there. This ordinarily should not be a problem but the zipimporter caches metadata by filename instead of stat/sha, so if the underlying contents changed a runtime error would be thrown due to seemingly corrupt zip file offsets. `RB #684 <https://rbcommons.com/s/twitter/r/684/>`_0.5.8-----* Adds ``-i/--index`` option to the pex tool.0.5.7-----* Adds ``twitter.common.python.pex_bootstrap`` ``bootstrap_pex_env`` function in order to initialize a PEX environment from within a python interpreter. (Patch contributed by @kwlzn)* Adds stdin=,stdout=,stderr= keyword parameters to the ``PEX.run`` function. (Patch from @benjy)0.5.6-----* The crawler now defaults to not follow links for security reasons. (Before the default behavior was to implicitly ``--follow-links`` for all requirements.) `RB #293 <https://rbcommons.com/s/twitter/r/293/>`_0.5.5-----* Improves scrubbing of site-packages from PEX environments. `RB #289 <https://rbcommons.com/s/twitter/r/289/>`_0.5.1 - 0.5.4-------------* Silences exceptions reported during interpreter teardown (the exceptions resulting from incorrect atexit handler behavior) introduced by 0.4.3 `RB #253 <https://rbcommons.com/s/twitter/r/253/>`_ `RB #249 <https://rbcommons.com/s/twitter/r/249/>`_* Adds ``__hash__`` to ``Link`` so that Packages are hashed correctly in ``twitter.common.python.resolver`` ``resolve``0.5.0-----* Adds wheel support to ``twitter.common.python`` `RB #94 <https://rbcommons.com/s/twitter/r/94/>`_ `RB #154 <https://rbcommons.com/s/twitter/r/154/>`_ `RB #148 <https://rbcommons.com/s/twitter/r/148/>`_0.4.3-----* Adds ``twitter.common.python.finders`` which are additional finders for setuptools including: - find eggs within a .zip - find wheels within a directory - find wheels within a .zip `RB #86 <https://rbcommons.com/s/twitter/r/86/>`_* Adds a new Package abstraction by refactoring Link into Link and Package. `RB #92 <https://rbcommons.com/s/twitter/r/92/>`_* Adds support for PEP425 tagging necessary for wheel support. `RB #87 <https://rbcommons.com/s/twitter/r/87/>`_* Improves python environment isolation by correctly scrubbing namespace packages injected into module ``__path__`` attributes by nspkg pth files. `RB #116 <https://rbcommons.com/s/twitter/r/116/>`_* Adds ``twitter.common.python.resolver`` ``resolve`` method that handles transitive dependency resolution better. This means that if the requirement ``futures==2.1.2`` and an unqualified ``futures>=2`` is pulled in transitively, our resolver will correctly resolve futures 2.1.2 instead of reporting a VersionConflict if any version newer than 2.1.2 is available. `RB #129 <https://rbcommons.com/s/twitter/r/129/>`_* Factors all ``twitter.common.python`` test helpers into ``twitter.common.python.testing`` `RB #91 <https://rbcommons.com/s/twitter/r/91/>`_* Bug fix: Fix ``OrderedSet`` atexit exceptions `RB #147 <https://rbcommons.com/s/twitter/r/147/>`_* Bug fix: Fix cross-device symlinking (patch from @benjy)* Bug fix: Raise a ``RuntimeError`` if we fail to write ``pkg_resources`` into a .pex `RB #115 <https://rbcommons.com/s/twitter/r/115/>`_0.4.2-----* Upgrade to ``setuptools>=1``0.4.1-----* ``twitter.common.python`` is no longer a namespace package0.4.0-----* Kill the egg distiller. We now delegate .egg generation to bdist_egg. `RB #55 <https://rbcommons.com/s/twitter/r/55/>`_0.3.1-----* Short-circuit resolving a distribution if a local exact match is found. `RB #47 <https://rbcommons.com/s/twitter/r/47/>`_* Correctly patch the global ``pkg_resources`` ``WorkingSet`` for the lifetime of the Python interpreter. `RB #52 <https://rbcommons.com/s/twitter/r/52/>`_* Fixes a performance regression in setuptools ``build_zipmanifest`` `Setuptools Issue #154 <https://bitbucket.org/pypa/setuptools/issue/154/build_zipmanifest-results-should-be>`_ `RB #53 <https://rbcommons.com/s/twitter/r/53/>`_0.3.0-----* Plumb through the ``--zip-safe``, ``--always-write-cache``, ``--ignore-errors`` and ``--inherit-path`` flags to the pex tool.* Delete the unused ``PythonDirWrapper`` code.* Split ``PEXEnvironment`` resolution into ``twitter.common.python.environment`` and deconflate ``WorkingSet``/``Environment`` state.* Removes the monkeypatched zipimporter in favor of keeping all eggs unzipped within PEX files. Refactors the PEX dependency cache in ``util.py``* Adds interpreter detection for Jython and PyPy.* Dependency translation errors should be made uniform. (Patch from @johnsirois)* Adds ``PEX_PROFILE_ENTRIES`` to limit the number of entries reported when ``PEX_PROFILE`` is enabled. (Patch from @rgs_)* Bug fix: Several fixes to error handling in ``twitter.common.python.http`` (From Marc Abramowitz)* Bug fix: PEX should not always assume that ``$PATH`` was available. (Patch from @jamesbroadhead)* Bug fix: Filename should be part of the .pex cache key or else multiple identical versions will incorrectly resolve (Patch from @tc)* Bug fix: Executed entry points shouldn't be forced to run in an environment with ``__future__`` imports enabled. (Patch from @lawson_patrick)* Bug fix: Detect versionless egg links and fail fast. (Patch from @johnsirois.)* Bug fix: Handle setuptools>=2.1 correctly in the zipimport monkeypatch (Patch from @johnsirois.)0.2.3-----* Bug fix: Fix handling of Fetchers with ``file://`` urls.0.2.2-----* Adds the pex tool as a standalone tool.0.2.1-----* Bug fix: Bootstrapped ``twitter.common.python`` should declare ``twitter.common`` as a namespace package.0.2.0-----* Make ``twitter.common.python`` fully standalone by consolidating external dependencies within ``twitter.common.python.common``.0.1.0-----* Initial published version of ``twitter.common.python``.
