Munging of paths passed inside the system() interpreter command is no
longer supported. You have to pass your paths to posix_spawn() or the
execve() family of functions if you want them to be munged. The first
three characters must match `^/[a-z]/` in which case, it'll be turned
into a DOS-style drive path with backslashes.
- Introduce MAP_JIT which is zero on other platforms
- Invent __jit_begin() and __jit_end() which wrap Apple's APIs
- Runtime dispatch to sys_icache_invalidate() in __clear_cache()
- 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)
After hearing horror stories from a trusted colleague, I don't think
this is the kind of API we want to be supporting. Also SQLite wisdom
regarding fdatasync() has been added to the documentation.
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.
* [metal] Ensure DF is clear when calling C from exception handler
* [metal] Mark some internal routines and declarations as `@internal`
* [metal] Fix crash under UEFI when command line string is NULL
* [metal] Fix argc & argv[] setting, & VM page freeing, for UEFI
Part of the memory occupied by the argv[] contents was
erroneously used for page tables & then later erroneously
freed. The symptom was that argv[0] would show up as an
empty string ("").
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.
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.
Using `cosmocc -std=c11` was causing `ucontext_t` to become misaligned.
This change also adds the GNU constants on x86_64 for accessing general
registers, so you will not need `#ifdef`s to support both Cosmo and GNU
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()
