2.1.95
This release brings two new pex3 lock features for
--style universal locks.
By default, universal locks are created to target all operating systems.
This can cause problems when you only target a subset of operating
systems and a lock transitive dependency that is conditional on an OS
you do not target is not lockable. The new
--target-system {linux,mac,windows} option allows you to restrict
the set of targeted OSes to work around this sort of issue. Since PEX
files currently only support running on Linux and Mac, specifying
--target-system linux --target-system mac is a safe way to
pre-emptively avoid these sorts of locking issues when creating a
universal lock.
Previously you could not specify the --platform\s or
--complete-platform\s you would be using later to build PEXes with
when creating a universal lock. You now can, and Pex will verify the
universal lock can support all the specified platforms.
As is usual there are also several bug fixes including properly
propagating PEX_EXTRA_SYS_PATH additions to forked Python processes,
fixing pex3 lock export to only attempt to export for the selected
target and avoiding too long shebang errors for --venv mode PEXes in
a robust way.
