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 |

About ===== _decimal.c is a wrapper for the libmpdec library. libmpdec is a fast C library for correctly-rounded arbitrary precision decimal floating point arithmetic. It is a complete implementation of Mike Cowlishaw/IBM's General Decimal Arithmetic Specification. Build process for the module ============================ As usual, the build process for _decimal.so is driven by setup.py in the top level directory. setup.py autodetects the following build configurations: 1) x64 - 64-bit Python, x86_64 processor (AMD, Intel) 2) uint128 - 64-bit Python, compiler provides __uint128_t (gcc) 3) ansi64 - 64-bit Python, ANSI C 4) ppro - 32-bit Python, x86 CPU, PentiumPro or later 5) ansi32 - 32-bit Python, ANSI C 6) ansi-legacy - 32-bit Python, compiler without uint64_t 7) universal - Mac OS only (multi-arch) It is possible to override autodetection by exporting: PYTHON_DECIMAL_WITH_MACHINE=value, where value is one of the above options. NOTE ==== decimal.so is not built from a static libmpdec.a since doing so led to failures on AIX (user report) and Windows (mixing static and dynamic CRTs causes locale problems and more).
