This changes *NSYNC to allocate waiters on the stack so our locks don't
need to depend on dynamic memory. This make our runtiem simpler, and it
also fixes bugs with thread cancellation support.
The stdio reader thread now appears to be working recursively along
cosmopolitan subprocesses. For example, it's now possible to launch
vim.com from the unbourne.com bestline repl, thanks to hacks plus a
bug fix to select() timeouts.

This change fixes Cosmopolitan so it has fewer opinions about compiler
warnings. The whole repository had to be cleaned up to be buildable in
-Werror -Wall mode. This lets us benefit from things like strict const
checking. Some actual bugs might have been caught too.

This change improves the dirstream library in a lot of respects,
especially for /zip/... files. Also turn off MAP_STACK on Aarch64
because Qemu seems to implement it differently than Linux and it's
probably responsible for a lot of mysterious crashes.
This way complex runtime features (e.g. ftrace, symbol tables) can
always yoink zipos support. This is important now that apelink.com
automates embedding symbol tables for multiple cpus.
This test fails if Cosmo builds from a path that contains an uppercase character.
Paths with uppercase characters aren’t so common in server Linux. But they are in *desktop* Linux. Guess how I…?
But I digress.
The real problem is that the path is lowercased on one line, but not the next:
```
self.file_name = support.TESTFN.lower()
self.file_path = FakePath(support.TESTFN)
```
Given that no other test in the suite lowercases `support.TESTFN`, I opted to remove it from the first line rather than adding it to the second.
This change has the insight that dwExitCode isn't an exit code but
rather should be used to pass the wait status. This lets us report
killing as a termination status, similar to UNIX. This change also
fixes the fact that exit(259) on Windows will break the parent due
way WIN32 is designed. We now work around that.
It turns out that NetBSD and OpenBSD, will let you have exit codes
beyond 255. This change will let you use them when it's possible.
This change makes posix_spawn_test no longer flaky on Windows, by (1)
fixing a race condition in wait(), and (2) removing a misguided vfork
implementation which was letting Windows bypass pthread_atfork().
- Remove PAGESIZE constant
- Fix realloc() documentation
- Fix ttyname_r() error reporting
- Make forking more reliable on Windows
- Make execvp() a few microseconds faster
- Make system() a few microseconds faster
- Tighten up the socket-related magic numbers
- Loosen restrictions on mmap() offset alignment

- Use mkstemp() as basis for mktemp(), tmpfile(), tmpfd()
- Fix flakes in pthread_cancel_test, unix_test, fork_test

- Let sockets be passed as stdio to subprocesses on Windows
- Improve security of bind() on Windows w/ SO_EXCLUSIVEADDRUSE
This change ports APE Loader to Linux AARCH64, so that Raspberry Pi
users can run programs like redbean, without the executable needing
to modify itself. Progress has also slipped into this change on the
issue of making progress better conforming to user expectations and
industry standards regarding which symbols we're allowed to declare
- tcgetpgrp(STDIN_FILENO) should be equal to getpgrp() on Windows also,
found while reading wget source code which uses this check to decide
whether to print to stderr or to a file
- IN6_ADDR_ARE_EQUAL is a comparison macro used when IPV6 is allowed,
found while reading CPython3.11 source code
- the changes in signal.h and addition of ucontext.h are because
CPython3.11 source code expect sigaltstack to be available
- the sqlite3.mk change is because CPython3.11 requires sqlite3 to be
built with -DOMIT_SHARED_CACHE
- unistd.h has getopt.h now, because some libraries like it there
This change introduces new tests for `O_NONBLOCK` and `SOCK_NONBLOCK` to
confirm that non-blocking i/o is now working on all supported platforms,
including Windows. For example, you can now say on Windows, MacOS, etc.:
socket(AF_INET, SOCK_STREAM | SOCK_NONBLOCK, IPPROTO_TCP);
To create a non-blocking IPv4 TCP socket. Or you can enable non-blocking
i/o on an existing socket / pipe / etc. file descriptor by calling fcntl
fcntl(fd, F_SETFL, fcntl(fd, F_GETFL) | O_NONBLOCK);
This functionality is polyfilled on older Linux kernels too, e.g. RHEL5.
Now that fcntl() support is much better the FIOCLEX / FIONCLEX polyfills
for ioctl() have been removed since they're ugly non-POSIX diameond APIs
This change fixes a weakness in kprintf() that was causing Windows trace
tools to frequently crash.
- This commit mints a new release of APE Loader v1.2 which supports
loading ELF programs with a non-contiguous virtual address layout
even though we've never been able to take advantage of it, due to
how `objcopy -SO binary` fills any holes left by PT_LOAD. This'll
change soon, since we'll have a new way of creating APE binaries.
- The undiamonding trick with our ioctl() implementation is removed
since POSIX has been killing ioctl() for years and they've done a
much better job. One problem it resolves, is that ioctl(FIONREAD)
wasn't working earlier and that caused issues when building Emacs
- Fix unused local variable errors
- Remove yoinks from sigaction() header
- Add nox87 and aarch64 to github actions

- MODE=tinylinux binaries are now back to being as tiny as ~4kb
- Improve the runtime's stack allocation / alignment hack
- GitHub Actions now tests Linux modes for assurance
- Fix handling of precision in hex float formatting
- Enhance the cocmd interpreter for system() and popen()
- Manually ran the Lua unit tests, which are now passing
- Let stdio i/o operations happen when file is in error state
- We're now saving and restoring xmm in ftrace out of paranoia
It turned out that Landlock Make hasn't been applying sandboxing for a
while, due to a mistyped if statement for `$(USE_SYSTEM_TOOLCHAIN)` it
should have had the opposite meaning. Regressions in the build configs
have been fixed. The rmrf() function works better now. The rm.com tool
works according to POSIX with the exception of supporting prompts.
