* bpo-45953: Statically allocate the main interpreter (and initial thread ↵Eric Snow2022-01-122-17/+34
| | | | | | | | | state). (gh-29883) Previously, the main interpreter was allocated on the heap during runtime initialization. Here we instead embed it into _PyRuntimeState, which means it is statically allocated as part of the _PyRuntime global. The same goes for the initial thread state (of each interpreter, including the main one). Consequently there are fewer allocations during runtime/interpreter init, fewer possible failures, and better memory locality. FYI, this also helps efforts to consolidate globals, which in turns helps work on subinterpreter isolation. https://bugs.python.org/issue45953

* bpo-45953: Statically allocate and initialize global bytes objects. (gh-30096)Eric Snow2022-01-111-6/+0
| | | | | The empty bytes object (b'') and the 256 one-character bytes objects were allocated at runtime init. Now we statically allocate and initialize them. https://bugs.python.org/issue45953
* bpo-46331: Do not set line number of instruction storing doc-string. (GH-30518)Mark Shannon2022-01-111-0/+1

* bpo-46303: Move fileutils.h private functions to internal C API (GH-30484)Victor Stinner2022-01-111-0/+2
| | | | | | | | | | Move almost all private functions of Include/cpython/fileutils.h to the internal C API Include/internal/pycore_fileutils.h. Only keep _Py_fopen_obj() in Include/cpython/fileutils.h, since it's used by _testcapi which must not use the internal C API. Move EncodeLocaleEx() and DecodeLocaleEx() functions from _testcapi to _testinternalcapi, since the C API moved to the internal C API.

* bpo-45953: Statically initialize the small ints. (gh-30092)Eric Snow2021-12-141-2/+0
| | | | | | | The array of small PyLong objects has been statically declared. Here I also statically initialize them. Consequently they are no longer initialized dynamically during runtime init. I've also moved them under a new sub-struct in _PyRuntimeState, in preparation for static allocation and initialization of other global objects. https://bugs.python.org/issue45953

* bpo-45582: Fix test_embed failure during a PGO build on Windows (GH-30014)neonene2021-12-101-0/+2
| | | This defines VPATH differently in PGO instrumentation builds, to account for a different default output directory. It also adds sys._vpath on Windows to make the value available to sysconfig so that it can be used in tests.
* bpo-43931: Export Python version as API data (GH-25577)Gabriele N. Tornetta2021-12-101-0/+3
| | | | | When Python is embedded in other applications, it is not easy to determine which version of Python is being used. This change exposes the Python version as part of the API data. Tools like Austin (https://github.com/P403n1x87/austin) can benefit from this data when targeting applications like uWSGI, as the Python version can then be inferred systematically by looking at the exported symbols rather than relying on unreliable pattern matching or other hacks (like remote code execution etc...).

* bpo-46008: Make runtime-global object/type lifecycle functions and state ↵Eric Snow2021-12-094-51/+100
| | | | | | | | | | | | consistent. (gh-29998) This change is strictly renames and moving code around. It helps in the following ways: * ensures type-related init functions focus strictly on one of the three aspects (state, objects, types) * passes in PyInterpreterState * to all those functions, simplifying work on moving types/objects/state to the interpreter * consistent naming conventions help make what's going on more clear * keeping API related to a type in the corresponding header file makes it more obvious where to look for it https://bugs.python.org/issue46008
