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.)
On aarch64 hosts, MODE= is changed to MODE=aarch64, so o// targets don't
work. So On aarch64, get apelink.com out of o/aarch64/. Also prepend ape
when calling it. And finally, fetch with curl when wget isn't installed.
I'm no longer able to reproduce the PE import table corruption that was
previously observed. Since this optimization shaves up to 64kb off each
fat APE binary we build, it's worth turning this back on again, to wait
and see if something breaks, and if so, fix it. At least until the next
release is shipped.
See #965
This change upgrades to superconfigure z0.0.23 which fixes an issue
where the compiler had harmless /home/... paths baked-in, which are
normally only present in the build environment, and usually skipped
over. Sadly on MacOS calling fstatat() on these paths would lead to
cloud file system ops that caused system calls to take a long time.
That's problematic, since cosmocc needs to be a 100% local command.
- Use good ELF technique in cosmo_dlopen()
- Make strerror() conform more to other libc impls
- Introduce __clear_cache() and use it in cosmo_dlopen()
- Remove libc/fmt/fmt.h header (trying to kill off LIBC_FMT)
It turns out my earlier commit ddc08dc974 caused a build with
MODE=aarch64 to fail. The commit changed deathstar.c to link
in code to support a VGA console, but this is not implemented
yet for AArch64. Thanks to @ahgamut for spotting this issue.
Imported functions are now aspected with a trampoline that blocks
signals and changes the thread-local storage register. This means
bigger more complicated libraries can now be imported even though
the whole technique remains fundamentally unsafe.
We now have an `#include <cxxabi.h>` header which defines all the APIs
Cosmopolitan's implemented so far. The `cosmocc` README.md file is now
greatly expanded with documentation.
The `cosmocc` compiler is now being distributed as a self-contained
toolchain that's path-agnostic and it no longer requires you clone the
Cosmop repo to use it. The bin/ folder has been deleted from the mono
repo. The `fatcosmocc` command has been renamed to `cosmocc`. MacOS
support now works very well.
Our makefile generator now accepts badly formatted include lines. It's
now more hermetic with better error checking in the cosmo repo, and it
can be configured to not be hermetic at all.
This change addresses a $PATH resolution issue where APE depends on
uname and uname is an APE program. So sorry to anyone this impacted
we'll get a release out soon.
wait4() is now solid enough to run `make -j100` on Windows. You can now
use MSG_DONTWAIT on Windows. There was a handle leak in accept() that's
been fixed. Our WIN32 overlapped i/o code has been simplified. Priority
class now inherits into subprocesses, so the verynice command will work
and the signal mask will now be inherited by execve() and posix_spawn()
This function was invented by the BSDs (it's not in POSIX.1). It
provides a high-level interface into ioctl(SIOCGIFCONF) which is
comparatively clumsy to use. We already made the ioctls portable
across our entire support vector back in 2021, so this interface
is portable too. See o//tool/viz/getifaddrs.com for our demo app
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.
- You can now run `make -j8 toolchain` on Windows
- You can now run `make -j` on MacOS ARM64 and BSD OSes
- You can now use our Emacs dev environment on MacOS/Windows
- Fix bug where the x16 register was being corrupted by --ftrace
- The programs under build/bootstrap/ are updated as fat binaries
- The Makefile now explains how to download cosmocc-0.0.12 toolchain
- The build scripts under bin/ now support "cosmo" branded toolchains
- stat() now goes faster on Windows (shaves 100ms off `make` latency)
- Code cleanup and added review on the Windows signal checking code
- posix_spawnattr_setrlimit() now works around MacOS ARM64 bugs
- Landlock Make now favors posix_spawn() on non-Linux/OpenBSD
- posix_spawn() now has better --strace logging on Windows
- fstatat() can now avoid EACCES in more cases on Windows
- fchmod() can now change the readonly bit on Windows
GNU Make on Windows now appears to be working reliably. This change also
fixes a bug where, after fork the Windows thread handle wasn't reset and
that caused undefined behavior using SetThreadContext() with our signals
This change gets GNU grep working. What caused it to not work, is it
wouldn't write to an output file descriptor when its dev/ino equaled
/dev/null's. So now we invent special dev/ino values for these files
