This release is a quick fix for a regression that inadvertently went out in 1.1.5 (Issue #243).
- Fix the
bdist_pex
setuptools
command to work for python2. #246 Fixes #243 - Upgrade pex dependencies on
setuptools
andwheel
. #244 Fixes #238
- Fix
PEXBuilder.clone
and thusbdist_pex --pex-args
for--python
and--python-shebang
. #234 Fixes #233 - Fix old
pkg_resources
egg version normalization. #227 Fixes #226 - Fix the
inherit_path
handling. #224 - Fix handling of bad distribution script names when used as the pex entrypoint. #221 Fixes #220
This release is a quick fix for a regression that inadvertently went out in 1.1.3 (Issue #216).
- Add a test for the regression in
FixedEggMetadata._zipinfo_name
and revert the breaking commit. Fixes #216
This release includes an initial body of work towards Windows support, ABI tag support for CPython 2.x and a fix for version number normalization.
- Add python 2.x abi tag support. #214 Fixes #213
- Add .idea to .gitignore. #205
- Don't normalize version numbers as names. #204
- More fixes for windows. #202
- Fixes to get pex to work on windows. #198
- Bump setuptools & wheel version pinning. #194
- Unescape html in PageParser.href_match_to_url. #191
- Memoize calls to Crawler.crawl() for performance win in find-links based resolution. #187
- Fix infinite recursion when
PEX_PYTHON
points at a symlink. #182 - Add
/etc/pexrc
to the list of pexrc locations to check. #183 - Improve error messaging for platform constrained Untranslateable errors. #179
- Add support for
.pexrc
files for influencing the pex environment. See the notes here. #128. - Bug fix: PEX_PROFILE_FILENAME and PEX_PROFILE_SORT were not respected. #154.
- Adds the
bdist_pex
command to setuptools. #99. - Bug fix: We did not normalize package names in
ResolvableSet
, so it was possible to depend onsphinx
andSphinx-1.4a0.tar.gz
and get two versions build and included into the pex. #147. - Adds a pex-identifying User-Agent. #101.
- 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 thePythonInterpreter
class. Fixes #144. - Bug fix: PEX_SCRIPT failed when the script was from a not-zip-safe egg. Original PR #139.
- Bug fix:
sys.exit
called without arguments would cause None to be printed on stderr since pex 1.0.1. #143.
- Bug fix: PEX-INFO values were overridden by environment
Variables
with default values that were not explicitly set in the environment. Fixes #135. - Bug fix: Since 69649c1 we have been unpatching
the side-effects of
sys.modules
afterPEX.execute
. This takes all modules imported during the PEX lifecycle and sets all their attributes toNone
. Unfortunately,sys.excepthook
,atexit
and__del__
may still try to operate using these tainted modules, causing exceptions on interpreter teardown. This reverts just thesys
unpatching so that the abovementioned teardown hooks behave more predictably. Fixes #141.
- 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.
- Bug fix: Fix complex resolutions when using a cache. Fixes: #120.
The 1.0.0 release of pex introduces a few breaking changes: pex -r
now takes requirements.txt files
instead 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 CLI changes will invoke a major version change. Any backwards incompatible changes to the PEX environment variable semantics will also result in a major version change. The pex API adheres to 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. - 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. - 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
orPEX_PYTHON=/exact/path/to/interpreter
. #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. - Consolidates documentation of
PEX_
environment variables and adds the--help-variables
option to the pex client. Partially addresses #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.
- Now supports extras for static URLs and installable directories. #65.
- Adds
-m
and--entry-point
alias to the existing-e
option for entry points in the pex tool to evoke the similarity topython -m
. - Adds console script support via
-c/--script/--console-script
andPEX_SCRIPT
. This allows you to reference the named entry point instead of the exactmodule:name
pair. Also supports scripts defined in thescripts
section of setup.py. #59. - Adds more debugging information when encountering unresolvable requirements. #79.
- Bug fix:
PEX_COVERAGE
andPEX_PROFILE
did not function correctly when SystemExit was raised. Fixes #81. - Bug fix: Fixes caching in the PEX tool since we don't cache the source distributions of installable directories. #24.
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 and #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 removingextras_requires
on theconsole_script
entry point. Fixes #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 in order to fix #48
- Bug fix: Honor installed sys.excepthook in pex teardown. RB #1733
- Bug fix:
UrllibContext
usedreplace
as a keyword argument forbytes.decode
but this only works on Python 3. Pull Request #46
- Bug fix: Fixup string formatting in pex/bin/pex.py to support Python 2.6 Pull Request #40
- Performance improvement: Speed up the best-case scenario of dependency resolution. RB #1685
- Bug fix: Change from
uuid4().get_hex()
touuid4().hex
to maintain Python3 compatibility of pex.common. Pull Request #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
- Bug fix: Support all potential abi tag permutations when determining platform compatibility. Pull Request #33
- 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
- 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.
- Bug fix: Fix issue where it'd be possible to
os.path.getmtime
on a remoteLink
object Issue #29
- 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 - Refactor http handling in pex to allow for alternate http implementations. Adds support for requests, improving both performance and security. For more information, read the commit notes at 91c7f32. RB #778
- Improvements to API documentation throughout.
- Renamed
Tracer
toTraceLogger
to prevent nondeterministic isort ordering. - Refactor tox.ini to increase the number of environment combinations and improve coverage.
- Adds HTTP retry support for the RequestsContext. RB #1303
- Make pex --version correct. Issue #19
- Bug fix: Fix over-aggressive sys.modules scrubbing for namespace packages. Under certain circumstances, namespace packages in site-packages could conflict with packages within a PEX, causing them to fail importing. RB #1378
- Bug fix: Replace uses of
os.unsetenv(...)
withdel os.environ[...]
Pull Request #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
- Bug fix: The pex -s option was not correctly pulling in transitive dependencies. Issue #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
- Rename
twitter.common.python
topex
and split out from the twitter/commons repo.
- Change the interpretation of
-i
(and of PyPIFetcher's pypi_base) to match pip's-i
. This is useful for compatibility with devpi.
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.
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
- Adds
-i/--index
option to the pex tool.
- 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)

(Before the default behavior was to implicitly
--follow-links
for all requirements.) RB #293

which are additional finders for setuptools including: - find eggs within a .zip - find wheels within a directory - find wheels within a .zip RB #86 - Adds a new Package abstraction by refactoring Link into Link and Package. RB #92
- Adds support for PEP425 tagging necessary for wheel support. RB #87
- Improves python environment isolation by correctly scrubbing namespace
packages injected into module
__path__
attributes by nspkg pth files. RB #116 - Adds
twitter.common.python.resolver
resolve
method that handles transitive dependency resolution better. This means that if the requirementfutures==2.1.2
and an unqualifiedfutures>=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 - Factors all
