From 2e58ff3ef56c3bf0a7080743ec77e95ca1758b97 Mon Sep 17 00:00:00 2001 From: Guido van Rossum Date: Wed, 19 Nov 1997 18:53:33 +0000 Subject: Fix importing of shared libraries from inside packages. This is a bit of a hack: when the shared library is loaded, the module name is "package.module", but the module calls Py_InitModule*() with just "module" for the name. The shared library loader squirrels away the true name of the module in _Py_PackageContext, and Py_InitModule*() will substitute this (if the name actually matches). --- Python/modsupport.c | 10 ++++++++++ 1 file changed, 10 insertions(+) (limited to 'Python/modsupport.c') diff --git a/Python/modsupport.c b/Python/modsupport.c index 854439bb94..12ecaf6b86 100644 --- a/Python/modsupport.c +++ b/Python/modsupport.c @@ -39,6 +39,9 @@ typedef extended va_double; typedef double va_double; #endif +/* Package context -- the full module name for package imports */ +char *_Py_PackageContext = NULL; + /* Py_InitModule4() parameters: - name is the module name - methods is the list of top-level functions @@ -69,6 +72,13 @@ Py_InitModule4(name, methods, doc, passthrough, module_api_version) if (module_api_version != PYTHON_API_VERSION) fprintf(stderr, api_version_warning, name, PYTHON_API_VERSION, name, module_api_version); + if (_Py_PackageContext != NULL) { + char *p = strrchr(_Py_PackageContext, '.'); + if (p != NULL && strcmp(name, p+1) == 0) { + name = _Py_PackageContext; + _Py_PackageContext = NULL; + } + } if ((m = PyImport_AddModule(name)) == NULL) return NULL; d = PyModule_GetDict(m); -- cgit v1.2.1
