Add chibicc This program popped up on Hacker News recently. It's the only modern compiler I've ever seen that doesn't have dependencies and is easily modified. So I added all of the missing GNU extensions I like to use which means it might be possible soon to build on non-Linux and have third party not vendor gcc binaries.

Improve memory safety This commit makes numerous refinements to cosmopolitan memory handling. The default stack size has been reduced from 2mb to 128kb. A new macro is now provided so you can easily reconfigure the stack size to be any value you want. Work around the breaking change by adding to your main: STATIC_STACK_SIZE(0x00200000); // 2mb stack If you're not sure how much stack you need, then you can use: STATIC_YOINK("stack_usage_logging"); After which you can `sort -nr o/$MODE/stack.log`. Based on the unit test suite, nothing in the Cosmopolitan repository (except for Python) needs a stack size greater than 30kb. There are also new macros for detecting the size and address of the stack at runtime, e.g. GetStackAddr(). We also now support sigaltstack() so if you want to see nice looking crash reports whenever a stack overflow happens, you can put this in main(): ShowCrashReports(); Under `make MODE=dbg` and `make MODE=asan` the unit testing framework will now automatically print backtraces of memory allocations when things like memory leaks happen. Bugs are now fixed in ASAN global variable overrun detection. The memtrack and asan runtimes also handle edge cases now. The new tools helped to identify a few memory leaks, which are fixed by this change. This change should fix an issue reported in #288 with ARG_MAX limits. Fixing this doubled the performance of MKDEPS.COM and AR.COM yet again.

Improve ZIP filesystem and change its prefix The ZIP filesystem has a breaking change. You now need to use /zip/ to open() / opendir() / etc. assets within the ZIP structure of your APE binary, instead of the previous convention of using zip: or zip! URIs. This is needed because Python likes to use absolute paths, and having ZIP paths encoded like URIs simply broke too many things. Many more system calls have been updated to be able to operate on ZIP files and file descriptors. In particular fcntl() and ioctl() since Python would do things like ask if a ZIP file is a terminal and get confused when the old implementation mistakenly said yes, because the fastest way to guarantee native file descriptors is to dup(2). This change also improves the async signal safety of zipos and ensures it doesn't maintain any open file descriptors beyond that which the user has opened. This change makes a lot of progress towards adding magic numbers that are specific to platforms other than Linux. The philosophy here is that, if you use an operating system like FreeBSD, then you should be able to take advantage of FreeBSD exclusive features, even if we don't polyfill them on other platforms. For example, you can now open() a file with the O_VERIFY flag. If your program runs on other platforms, then Cosmo will automatically set O_VERIFY to zero. This lets you safely use it without the need for #ifdef or ifstatements which detract from readability. One of the blindspots of the ASAN memory hardening we use to offer Rust like assurances has always been that memory passed to the kernel via system calls (e.g. writev) can't be checked automatically since the kernel wasn't built with MODE=asan. This change makes more progress ensuring that each system call will verify the soundness of memory before it's passed to the kernel. The code for doing these checks is fast, particularly for buffers, where it can verify 64 bytes a cycle. - Correct O_LOOP definition on NT - Introduce program_executable_name - Add ASAN guards to more system calls - Improve termios compatibility with BSDs - Fix bug in Windows auxiliary value encoding - Add BSD and XNU specific errnos and open flags - Add check to ensure build doesn't talk to internet

Improve Libc by making Python work even better Actually Portable Python is now outperforming the Python binaries that come bundled with Linux distros, at things like HTTP serving. You can now have a fully featured Python install in just one .com file that runs on six operating systems and is about 10mb in size. With tuning, the tiniest is ~1mb. We've got most of the libraries working, including pysqlite, and the repl now feels very pleasant. The things you can't do quite yet are: threads and shared objects but that can happen in the future, if the community falls in love with this project and wants to see it developed further. Changes: - Add siginterrupt() - Add sqlite3 to Python - Add issymlink() helper - Make GetZipCdir() faster - Add tgamma() and finite() - Add legacy function lutimes() - Add readlink() and realpath() - Use heap allocations when appropriate - Reorganize Python into two-stage build - Save Lua / Python shell history to dotfile - Integrate Python Lib embedding into linkage - Make isregularfile() and isdirectory() go faster - Make Python shell auto-completion work perfectly - Make crash reports work better if changed directory - Fix Python+NT open() / access() flag overflow error - Disable Python tests relating to \N{LONG NAME} syntax - Have Python REPL copyright() show all notice embeddings The biggest technical challenge at the moment is working around when Python tries to be too clever about filenames.
