This change reduces the memory requirements of your APE Loader by 10x,
in terms of virtual memory size, thanks to the help of alloca(). We're
also now creating argument blocks with the same layout across systems.
- Fix mkdeps.com out of memory error
- Remove static memory from __get_cpu_count()
- Add support for passing hyphen to cat in cocmd
- Change more ZipOS errors from ENOTSUP to EROFS
- Specify mem_unit in sysinfo() output on BSD OSes
readdir() will now always yield an inode that's consistent with stat()
on ZipOS and Windows in general. More APIs have been updated to return
the appropriate error code when inappropriately trying to do ops, like
sockets, with a zip file descriptor. The path normalization algorithms
are now fully fleshed out. Some socket APIs have been fixed so they'll
raise EBADF vs. ENOTSOCK appropriately. Lastly seekdir() will now work
properly on NetBSD and FreeBSD (not sure why anyone would even use it)
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.
You can now play Super Mario Bros in CMD.EXE using Cosmopolitan! This is
thanks to a new worker thread that's spawned on Windows whenever any one
of poll(), select(), or ioctl(FIONREAD) is linked.
make all test CC=fatcosmocc AR='fatcosmoar rcu'
This change introduces a program named mktemper.com which provides more
reliable and secure temporary file name generation for scripts. It also
makes our ar.com program more permissive in what commands it'll accept.
The cosmocc command is improved by this change too.
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 new script is an alternative to the `cosmocc` command. It's still a
work in progress. It abstracts all the gory details of building separate
copies of your executable and then running the apelink.com program.
If you build a static ELF executable in `ld -q` mode (which leaves rela
sections inside the binary) then you can run it through the elf2pe.com
program afterwards, which will turn it into a PE executable. We have a
new trick for defining WIN32 DLL imports in C without any assembly code.
This also achieves the optimally tiny and perfect PE binary structure.
We need this because it isn't possible to have a GNU ld linker script
generate a PE file where the virtual pointer and the file pointer can
drift apart. This post-linker can do that. One cool benefit is we can
now use a smaller 512-byte alignment in the file, and an even bigger
64kb alignment for the segment virtual addresses, and the executable
ends up being smaller.
Another program introduced by this change is pecheck.com which can do
extensive linting of PE static executables to help explain why Windows
won't load it.
- Blocking read operations on the Windows Console can now EINTR
- Blocking read operations on Windows pipes now EINTR more reliably
- setitimer() will no longer be inherited across fork() on Windows
- It's now possible to use ECHO when the console is in raw mode
- The ECHOCTL flag now works correctly on the Windows Console
- The ICRNL flag now works correctly on the Windows Console
- pread() and pwrite() will now raise ESPIPE on Windows
- Opening /dev/tty on Windows is improved (untested)
- Overlapped I/O is now implemented in a better way
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
- Improve GetProgramExecutableName() with getenv("_")
- Use mkstemp() as basis for mktemp(), tmpfile(), tmpfd()
- Fix flakes in pthread_cancel_test, unix_test, fork_test
- Fix recently introduced futex stack overflow regression
- Let sockets be passed as stdio to subprocesses on Windows
- Improve security of bind() on Windows w/ SO_EXCLUSIVEADDRUSE
This change addresses everything from stack smashing to %SYSTEMROOT%
breaking socket(). Issues relating to compile.com not reporting text
printed to stderr has been resolved for Windows builds.
