You can now call functions like fork() from Lua and it'll work across
all supported platforms, including Windows. This gives you a level of
control of the system that Lua traditionally hasn't been able to have
due to its focus on old portable stdio rather modern POSIX APIs. Demo
code has been added to redbean-demo.com to show how it works.
This change also modifies Lua so that integer literals with a leading
zero will be interpreted as octal. That should help avoid shooting in
the foot with POSIX APIs that frequently use octal mode bits.
This change fixes a bug in opendir(".") on New Technology.
Lastly, redbean will now serve crash reports to private network IPs.
This is consistent with other frameworks. However that isn't served
to public IPs unless the -E flag is passed to redbean at startup.
- Better UBSAN error messages
- POSIX Advisory Locks polyfills
- Move redbean manual to /.help.txt
- System call memory safety in ASAN mode
- Character classification now does UNICODE
This change enables Address Sanitizer systemically w/ `make MODE=dbg`.
Our version of Rust's `unsafe` keyword is named `noasan` which is used
for two functions that do aligned memory chunking, like `strcpy.c` and
we need to fix the tiny DEFLATE code, but that's it everything else is
fabulous you can have all the fischer price security blankets you need
Best of all is we're now able to use the ASAN data in Blinkenlights to
colorize the memory dumps. See the screenshot below of a test program:
https://justine.lol/blinkenlights/asan.png
Which is operating on float arrays stored on the stack, with red areas
indicating poisoned memory, and the green areas indicate valid memory.
