Undiamond Python headers This change gets the Python codebase into a state where it conforms to the conventions of this codebase. It's now possible to include headers from Python, without worrying about ordering. Python has traditionally solved that problem by "diamonding" everything in Python.h, but that's problematic since it means any change to any Python header invalidates all the build artifacts. Lastly it makes tooling not work. Since it is hard to explain to Emacs when I press C-c C-h to add an import line it shouldn't add the header that actually defines the symbol, and instead do follow the nonstandard Python convention. Progress has been made on letting Python load source code from the zip executable structure via the standard C library APIs. System calss now recognizes zip!FILENAME alternative URIs as equivalent to zip:FILENAME since Python uses colon as its delimiter. Some progress has been made on embedding the notice license terms into the Python object code. This is easier said than done since Python has an extremely complicated ownership story. - Some termios APIs have been added - Implement rewinddir() dirstream API - GetCpuCount() API added to Cosmopolitan Libc - More bugs in Cosmopolitan Libc have been fixed - zipobj.com now has flags for mangling the path - Fixed bug a priori with sendfile() on certain BSDs - Polyfill F_DUPFD and F_DUPFD_CLOEXEC across platforms - FIOCLEX / FIONCLEX now polyfilled for fast O_CLOEXEC changes - APE now supports a hybrid solution to no-self-modify for builds - Many BSD-only magnums added, e.g. O_SEARCH, O_SHLOCK, SF_NODISKIO

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.
