pex 2.0.0
2.0.0
Pex 2.0.0 is cut on the advent of a large, mostly internal change for typical
use cases: it now uses vendored pip to perform resolves and wheel builds. This
fixes a large number of compatibility and correctness bugs as well as gaining
feature support from pip including handling manylinux2010 and manylinux2014 as
well as VCS requirements and support for PEP-517 & PEP-518 builds.
API changes to be wary of:
- The egg distribution format is no longer supported.
- The deprecated
--interpreter-cache-dir
CLI option was removed. - The
--cache-ttl
CLI option andcache_ttl
resolver API argument were
removed. - The resolver API replaced
fetchers
with a list ofindexes
and a list
offind_links
repos. - The resolver API removed (http)
context
which is now automatically
handled. - The resolver API removed
precedence
which is now pip default precedence:
wheels when available and not ruled out via the--no-wheel
CLI option or
use_wheel=False
API argument. - The
--platform
CLI option andplatform
resolver API argument now must
be full platform strings that include platform, implementation, version and
abi; e.g.:--platform=macosx-10.13-x86_64-cp-36-m
. - The
--manylinux
CLI option anduse_manylinux
resolver API argument
were removed. Instead, to resolve manylinux wheels for a foreign platform,
specify the manylinux platform to target with an explicit--platform
CLI
flag orplatform
resolver API argument; e.g.:
--platform=manylinux2010-x86_64-cp-36-m
.
In addition, Pex 2.0.0 now builds reproduceable pexes by default; ie:
- Python modules embedded in the pex are not pre-compiled (pass --compile if
you want this). - The timestamps for Pex file zip entries default to midnight on
January 1, 1980 (pass --use-system-time to change this).
This finishes off the effort tracked by #716.
