This change is almost entirely moving code around and hiding import state behind internal API. We introduce no changes to behavior, nor to non-internal API. (Since there was already going to be a lot of churn, I took this as an opportunity to re-organize import.c into topically-grouped sections of code.) The motivation is to simplify a number of upcoming changes. Specific changes: * move existing import-related code to import.c, wherever possible * add internal API for interacting with import state (both global and per-interpreter) * use only API outside of import.c (to limit churn there when changing the location, etc.) * consolidate the import-related state of PyInterpreterState into a single struct field (this changes layout slightly) * add macros for import state in import.c (to simplify changing the location) * group code in import.c into sections *remove _PyState_AddModule() https://github.com/python/cpython/issues/101758 |

Welcome to the "PC" subdirectory of the Python distribution *********************************************************** This "PC" subdirectory contains complete project files to make several older PC ports of Python, as well as all the PC-specific Python source files. It should be located in the root of the Python distribution, and there should be directories "Modules", "Objects", "Python", etc. in the parent directory of this "PC" subdirectory. Be sure to read the documentation in the Python distribution. Python requires library files such as string.py to be available in one or more library directories. The search path of libraries is set up when Python starts. To see the current Python library search path, start Python and enter "import sys" and "print sys.path". All PC ports use this scheme to try to set up a module search path: 1) The script location; the current directory without script. 2) The PYTHONPATH variable, if set. 3) Paths specified in the Registry. 4) Default directories lib, lib/win, lib/test, lib/tkinter; these are searched relative to the environment variable PYTHONHOME, if set, or relative to the executable and its ancestors, if a landmark file (Lib/string.py) is found , or the current directory (not useful). 5) The directory containing the executable. The best installation strategy is to put the Python executable and DLL in some convenient directory such as C:/python, and copy all library files and subdirectories (using XCOPY) to C:/python/lib. Then you don't need to set PYTHONPATH. Otherwise, set the environment variable PYTHONPATH to your Python search path. For example, set PYTHONPATH=.;d:\python\lib;d:\python\lib\win;d:\python\lib\dos-8x3 There are several add-in modules to build Python programs which use the native Windows operating environment. The ports here just make "QuickWin" and DOS Python versions which support a character-mode (console) environment. Look in www.python.org for Tkinter, PythonWin, WPY and wxPython. To make a Python port, start the Integrated Development Environment (IDE) of your compiler, and read in the native "project file" (or makefile) provided. This will enable you to change any source files or build settings so you can make custom builds. pyconfig.h An important configuration file specific to PC's. config.c The list of C modules to include in the Python PC version. Manually edit this file to add or remove Python modules. Additional files and subdirectories for 32-bit Windows ====================================================== python_nt.rc Resource compiler input for python15.dll. dl_nt.c Additional sources used for 32-bit Windows features. getpathp.c Default sys.path calculations (for all PC platforms). dllbase_nt.txt A (manually maintained) list of base addresses for various DLLs, to avoid run-time relocation. Note for Windows 3.x and DOS users ================================== Neither Windows 3.x nor DOS is supported any more. The last Python version that supported these was Python 1.5.2; the support files were present in Python 2.0 but weren't updated, and it is not our intention to support these platforms for Python 2.x.
