Make major improvements to redbean and libraries The most exciting improvement is dynamic pages will soon be able to use the executable itself as an object store. it required a heroic technique for overcoming ETXTBSY restrictions which lets us open the executable in read/write mode, which means (1) wa can restore the APE header, and (2) we can potentially containerize redbean extension code so that modules you download for your redbean online will only impact your redbean. Here's a list of breaking changes to redbean: - Remove /tool/net/ prefix from magic ZIP paths - GetHeader() now returns NIL if header is absent Here's a list of fixes and enhancements to redbean: - Support 64-bit ZIP archives - Record User-Agent header in logs - Add twelve error handlers to accept() - Display octal st_mode on listing page - Show ZIP file comments on listing page - Restore APE MZ header on redbean startup - Track request count on redbean index page - Report server uptime on redbean index page - Don't bind server socket using SO_REUSEPORT - Fix #151 where Lua LoadAsset() could free twice - Report rusage accounting when workers exit w/ -vv - Use ZIP iattr field as text/plain vs. binary hint - Add ParseUrl() API for parsing things like a.href - Add ParseParams() API for parsing HTTP POST bodies - Add IsAcceptablePath() API for checking dots, etc. - Add IsValidHttpToken() API for validating sane ASCII - Add IsAcceptableHostPort() for validating HOST[:PORT] - Send 400 response to HTTP/1.1 requests without a Host - Send 403 response if ZIP or file isn't other readable - Add virtual hosting that tries prepending Host to path - Route requests based on Host in Request-URI if present - Host routing will attempt to remove or add the www. prefix - Sign-extend UNIX timestamps and don't adjust FileTime zone Here's some of the improvements made to Cosmopolitan Libc: - Fix ape.S indentation - Improve consts.sh magnums - Write pretty good URL parser - Improve rusage accounting apis - Bring mremap() closer to working - Added ZIP APIs which will change - Check for overflow in reallocarray() - Remove overly fancy linkage in strerror() - Fix GDB attach on crash w/ OpenBSD msyscall() - Make sigqueue() portable to most UNIX distros - Make integer serialization macros more elegant - Bring back 34x tprecode8to16() performance boost - Make malloc() more resilient to absurdly large sizes

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

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
