This is a breaking change. It defines the new environment variable named
_COSMO_FDS_V2 which is used for inheriting non-stdio file descriptors on
execve() or posix_spawn(). No effort has been spent thus far integrating
with the older variable. If a new binary launches the older ones or vice
versa they'll only be able to pass stdin / stdout / stderr to each other
therefore it's important that you upgrade all your cosmo binaries if you
depend on this functionality. You'll be glad you did because inheritance
of file descriptors is more aligned with the POSIX standard than before.
At least in neovim, `│vi:` is not recognized as a modeline because it
has no preceding whitespace. After fixing this, opening a file yields
an error because `net` is not an option. (`noet`, however, is.)
This change gets the pledge (formerly pledge.com) command back in tip
top shape for a 3.0.1 cosmos release. It now runs on all platforms, even
though it's mostly a no-op on ones that lack the kernel security stuff.
The binary footprint is now smaller, since it no longer needs to link
malloc. It's also now able to be built as a fat binary.
This change fixes bugs in the APE loader. The execve() unit tests are
now enabled for MODE=aarch64. See the README for how you need to have
binfmt_misc configured with Qemu to run them. Apple Silicon bugs have
been fixed too, e.g. tkill() now works.
