cpython-lru_cache-weakref: Python/compile.c annotate

annotate Python/compile.c @ 7290:72d531d54572 legacy-trunk

Add case checking feature on import. This is an option for OS-es with case-insensitive but case-preserving filesystems. It is currently supported for Win32 and MacOS. To enable it, #define CHECK_IMPORT_CASE in your platform specific config.h. It is enabled by default on those systems where it is supported. On Win32, it can be disabled at runtime by setting the environment variable PYTHONCASEOK (to any value). When enabled, the feature checks that the case of the requested module name matches that of the filename found in the filesystem, and raises a NameError exception when they don't match.
