* bpo-37444: Update differing exception between builtins and importlib (GH-14869)Ngalim Siregar2019-08-031-1/+1
| | | | | | | | | | Imports now raise `TypeError` instead of `ValueError` for relative import failures. This makes things consistent between `builtins.__import__` and `importlib.__import__` as well as using a more natural import for the failure. https://bugs.python.org/issue37444 Automerge-Triggered-By: @brettcannon

* bpo-36710: Add tstate parameter in import.c (GH-14218)Victor Stinner2019-06-191-155/+207
| | | | | | | | | | | | | * Add 'tstate' parameter to many internal import.c functions. * _PyImportZip_Init() now gets 'tstate' parameter rather than 'interp'. * Add 'interp' parameter to _PyState_ClearModules() and rename it to _PyInterpreterState_ClearModules(). * Move private _PyImport_FindBuiltin() to the internal C API; add 'tstate' parameter to it. * Remove private _PyImport_AddModuleObject() from the C API: use public PyImport_AddModuleObject() instead. * Remove private _PyImport_FindExtensionObjectEx() from the C API: use private _PyImport_FindExtensionObject() instead.

| | | | | | | | | | (GH-10284) Two kind of mistakes: 1. Missed space. After concatenating there is no space between words. 2. Missed comma. Causes unintentional concatenating in a list of strings.
* bpo-35081: And pycore_lifecycle.h and pycore_pathconfig.h (GH-10273)Victor Stinner2018-11-011-0/+1

* rename _imp initialization function to follow conventions (#5432)Benjamin Peterson2018-01-291-2/+1
| | | When the C imp module became _imp in 6f44d66bc491bad5b8d897a68da68e009e27829d, the initialization function should have been renamed from PyInit_imp to PyInit__imp.
* fix up signedness in PyImport_ExtendInittab (#4831)Benjamin Peterson2017-12-161-5/+3
| | | | | | | | | | As a result of 92a3c6f493ad411e4cf0acdf305ef4876aa90669, the compiler complains: Python/import.c:2311:21: warning: comparison of integers of different signs: 'long' and 'unsigned long' [-Wsign-compare] if ((i + n + 1) <= PY_SSIZE_T_MAX / sizeof(struct _inittab)) { ~~~~~~~~~ ^ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ This overflow is extremely unlikely to happen, but let's avoid undefined behavior anyway.

* closes bpo-31650: PEP 552 (Deterministic pycs) implementation (#4575)Benjamin Peterson2017-12-091-0/+42
| | | | | | | | | | | | | | | | | | | | | | | | | Python now supports checking bytecode cache up-to-dateness with a hash of the source contents rather than volatile source metadata. See the PEP for details. While a fairly straightforward idea, quite a lot of code had to be modified due to the pervasiveness of pyc implementation details in the codebase. Changes in this commit include: - The core changes to importlib to understand how to read, validate, and regenerate hash-based pycs. - Support for generating hash-based pycs in py_compile and compileall. - Modifications to our siphash implementation to support passing a custom key. We then expose it to importlib through _imp. - Updates to all places in the interpreter, standard library, and tests that manually generate or parse pyc files to grok the new format. - Support in the interpreter command line code for long options like --check-hash-based-pycs. - Tests and documentation for all of the above.

* bpo-32030: Add _PyImport_Fini2() (#4737)Victor Stinner2017-12-061-11/+41
| | | | | | | | | | | | | | | | | | | | | PyImport_ExtendInittab() now uses PyMem_RawRealloc() rather than PyMem_Realloc(). PyImport_ExtendInittab() can be called before Py_Initialize() whereas only the PyMem_Raw allocator is supposed to be used before Py_Initialize(). Add _PyImport_Fini2() to release the memory allocated by PyImport_ExtendInittab() at exit. PyImport_ExtendInittab() now forces the usage of the default raw allocator, to be able to release memory in _PyImport_Fini2(). Don't export these functions anymore to be C API, only to Py_BUILD_CORE: * _PyExc_Fini() * _PyImport_Fini() * _PyGC_DumpShutdownStats() * _PyGC_Fini() * _PyType_Fini() * _Py_HashRandomization_Fini()
* bpo-32030: pass interp to _PyImport_Init() (#4736)Victor Stinner2017-12-061-9/+1
| | | | | Remove also the initstr variable, unused since the commit e69f0df45b709c25ac80617c41bbae16f56870fb pushed in 2012: "bpo-13959: Re-implement imp.find_module() in Lib/imp.py"
* Refactor PyImport_ImportModuleLevelObject(). (#4680)Neil Schemenauer2017-12-031-50/+57
| | | | | | Add import_find_and_load() helper function. The addition of the importtime option has made PyImport_ImportModuleLevelObject() large and so using a helper seems worthwhile. It also makes it clearer that abs_name is the only argument needed by _find_and_load().
* bpo-32030: Add more options to _PyCoreConfig (#4485)Victor Stinner2017-11-211-4/+3
| | | | | | Py_Main() now handles two more -X options: * -X showrefcount: new _PyCoreConfig.show_ref_count field * -X showalloccount: new _PyCoreConfig.show_alloc_count field
* bpo-32030: Enhance Py_Main() (#4412)Victor Stinner2017-11-161-25/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Parse more env vars in Py_Main(): * Add more options to _PyCoreConfig: * faulthandler * tracemalloc * importtime * Move code to parse environment variables from _Py_InitializeCore() to Py_Main(). This change fixes a regression from Python 3.6: PYTHONUNBUFFERED is now read before calling pymain_init_stdio(). * _PyFaulthandler_Init() and _PyTraceMalloc_Init() now take an argument to decide if the module has to be enabled at startup. * tracemalloc_start() is now responsible to check the maximum number of frames. Other changes: * Cleanup Py_Main(): * Rename some pymain_xxx() subfunctions * Add pymain_run_python() subfunction * Cleanup Py_NewInterpreter() * _PyInterpreterState_Enable() now reports failure * init_hash_secret() now considers pyurandom() failure as an "user error": don't fail with abort(). * pymain_optlist_append() and pymain_strdup() now sets err on memory allocation failure.
