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
Building o//third_party/python now takes 5 seconds on my PC
This change works towards modifying Python to use runtime dispatching
when appropriate. For example, when loading the magnums in the socket
module, it's a good idea to check if the magnum is zero, because that
means the local system platform doesn't support it.
Modules/Setup and Modules/Setup.local contain the build recipes for
various extensions, wrote a custom script to translate them for
python.mk. Modules/config.c needs to be changed if any extensions are
removed or added.
Most of the source modifications are for missing headers or compile time
build vars like ABIFLAGS.
Created separate mk files for the C extensions and the Python stdlib.
Can use find for adding the python files to the APE ZIP store, but right
now necessary files are just hardcoded.
python.com loads but some build configs are still missing (showing 1 Jan
1970 as time of compilation).
These are the commits from
https://github.com/ahgamut/cpython/tree/cosmo_py36 squashed for
simplicity.
Also included is the pyconfig.h used for compilation. The pyconfig.h has
to be changed manually in case Cosmopolitan gets new features.
