* bpo-46541: Replace core use of _Py_IDENTIFIER() with statically initialized ↵Eric Snow2022-02-081-2/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | global objects. (gh-30928) We're no longer using _Py_IDENTIFIER() (or _Py_static_string()) in any core CPython code. It is still used in a number of non-builtin stdlib modules. The replacement is: PyUnicodeObject (not pointer) fields under _PyRuntimeState, statically initialized as part of _PyRuntime. A new _Py_GET_GLOBAL_IDENTIFIER() macro facilitates lookup of the fields (along with _Py_GET_GLOBAL_STRING() for non-identifier strings). https://bugs.python.org/issue46541#msg411799 explains the rationale for this change. The core of the change is in: * (new) Include/internal/pycore_global_strings.h - the declarations for the global strings, along with the macros * Include/internal/pycore_runtime_init.h - added the static initializers for the global strings * Include/internal/pycore_global_objects.h - where the struct in pycore_global_strings.h is hooked into _PyRuntimeState * Tools/scripts/generate_global_objects.py - added generation of the global string declarations and static initializers I've also added a --check flag to generate_global_objects.py (along with make check-global-objects) to check for unused global strings. That check is added to the PR CI config. The remainder of this change updates the core code to use _Py_GET_GLOBAL_IDENTIFIER() instead of _Py_IDENTIFIER() and the related _Py*Id functions (likewise for _Py_GET_GLOBAL_STRING() instead of _Py_static_string()). This includes adding a few functions where there wasn't already an alternative to _Py*Id(), replacing the _Py_Identifier * parameter with PyObject *. The following are not changed (yet): * stop using _Py_IDENTIFIER() in the stdlib modules * (maybe) get rid of _Py_IDENTIFIER(), etc. entirely -- this may not be doable as at least one package on PyPI using this (private) API * (maybe) intern the strings during runtime init https://bugs.python.org/issue46541

* bpo-28411: Isolate PyInterpreterState.modules (#3575)Eric Snow2017-09-141-1/+2
| | | | | A bunch of code currently uses PyInterpreterState.modules directly instead of PyImport_GetModuleDict(). This complicates efforts to make changes relative to sys.modules. This patch switches to using PyImport_GetModuleDict() uniformly. Also, a number of related uses of sys.modules are updated for uniformity for the same reason. Note that this code was already reviewed and merged as part of #1638. I reverted that and am now splitting it up into more focused parts.

| | | | | | | | | | | | | | | | | | | | | | | Known limitations of the current implementation: - documentation changes are incomplete - there's a reference leak I haven't tracked down yet The leak is most visible by running: ./python -m test -R3:3 test_importlib However, you can also see it by running: ./python -X showrefcount Importing the array or _testmultiphase modules, and then deleting them from both sys.modules and the local namespace shows significant increases in the total number of active references each cycle. By contrast, with _testcapi (which continues to use single-phase initialisation) the global refcounts stabilise after a couple of cycles.

| | | | | | | | | | Changes to make __file__ a proper Unicode object, using the default filesystem encoding. This is a bit tricky because the default filesystem encoding isn't set by the time we import the first modules; at that point we fudge things a bit. This is okay since __file__ isn't really used much except for error reporting. Tested on OSX and Linux only so far.

* SF patch #471839: Bug when extensions import extensions (Shane Hathaway)Guido van Rossum2001-10-161-2/+3
| | | | | | | | | | | | | | | | | When an extension imports another extension in its initXXX() function, the variable _Py_PackageContext is prematurely reset to NULL. If the outer extension then calls Py_InitModule(), the extension is installed in sys.modules without its package name. The manifestation of this bug is a "SystemError: _PyImport_FixupExtension: module <package>.<extension> not loaded". To fix this, importdl.c just needs to retain the old value of _Py_PackageContext and restore it after the initXXX() method is called. The attached patch does this. This patch applies to Python 2.1.1 and the current CVS.

| | | | | | | | | The following patches (relative to 1.5.2b1) enable Python dynamic loading to work on NetBSD platforms that use ELF (presnetly mips and alpha systems). They automaticly determine wether the system is ELF or a.out rather than using astatic list of platforms so that when other NetBSD platforms move to ELF, python will continue to work without change.
