* gh-98610: Adjust the Optional Restrictions on Subinterpreters (GH-98618)Eric Snow2022-10-311-5/+6
| | | | | | | Previously, the optional restrictions on subinterpreters were: disallow fork, subprocess, and threads. By default, we were disallowing all three for "isolated" interpreters. We always allowed all three for the main interpreter and those created through the legacy `Py_NewInterpreter()` API. Those settings were a bit conservative, so here we've adjusted the optional restrictions to: fork, exec, threads, and daemon threads. The default for "isolated" interpreters disables fork, exec, and daemon threads. Regular threads are allowed by default. We continue always allowing everything For the main interpreter and the legacy API. In the code, we add `_PyInterpreterConfig.allow_exec` and `_PyInterpreterConfig.allow_daemon_threads`. We also add `Py_RTFLAGS_DAEMON_THREADS` and `Py_RTFLAGS_EXEC`.

* gh-98608: Change _Py_NewInterpreter() to _Py_NewInterpreterFromConfig() ↵Eric Snow2022-10-261-0/+39
| | | | | | | | | | | | | | | | | | | | | | | | | (gh-98609) (see https://github.com/python/cpython/issues/98608) This change does the following: 1. change the argument to a new `_PyInterpreterConfig` struct 2. rename the function to `_Py_NewInterpreterFromConfig()`, inspired by `Py_InitializeFromConfig()` (takes a `_PyInterpreterConfig` instead of `isolated_subinterpreter`) 3. split up the boolean `isolated_subinterpreter` into the corresponding multiple granular settings * allow_fork * allow_subprocess * allow_threads 4. add `PyInterpreterState.feature_flags` to store those settings 5. add a function for checking if a feature is enabled on an opaque `PyInterpreterState *` 6. drop `PyConfig._isolated_interpreter` The existing default (see `Py_NewInterpeter()` and `Py_Initialize*()`) allows fork, subprocess, and threads and the optional "isolated" interpreter (see the `_xxsubinterpreters` module) disables all three. None of that changes here; the defaults are preserved. Note that the given `_PyInterpreterConfig` will not be used outside `_Py_NewInterpreterFromConfig()`, nor preserved. This contrasts with how `PyConfig` is currently preserved, used, and even modified outside `Py_InitializeFromConfig()`. I'd rather just avoid that mess from the start for `_PyInterpreterConfig`. We can preserve it later if we find an actual need. This change allows us to follow up with a number of improvements (e.g. stop disallowing subprocess and support disallowing exec instead). (Note that this PR adds "private" symbols. We'll probably make them public, and add docs, in a separate change.)

* gh-96512: Move int_max_str_digits setting to PyConfig (#96944)Gregory P. Smith2022-10-031-0/+33
| | | | | | | | | | | It had to live as a global outside of PyConfig for stable ABI reasons in the pre-3.12 backports. This removes the `_Py_global_config_int_max_str_digits` and gets rid of the equivalent field in the internal `struct _is PyInterpreterState` as code can just use the existing nested config struct within that. Adds tests to verify unique settings and configs in subinterpreters.

| | | | | | | | Added a new stable API function ``PyType_FromMetaclass``, which mirrors the behavior of ``PyType_FromModuleAndSpec`` except that it takes an additional metaclass argument. This is, e.g., useful for language binding tools that need to store additional information in the type object.

| | | | | | | | One more thing that can help prevent people from using `preexec_fn`. Also adds conditional skips to two tests exposing ASAN flakiness on the Ubuntu 20.04 Address Sanitizer Github CI system. When that build is run on more modern systems the "problem" does not show up. It seems ASAN implementation related. Co-authored-by: Zackery Spytz <zspytz@gmail.com> Co-authored-by: Serhiy Storchaka <storchaka@gmail.com>

* gh-91401: Add a failsafe way to disable vfork. (#91490)Gregory P. Smith2022-04-251-3/+3
| | | | | | | | | | | | | | Just in case there is ever an issue with _posixsubprocess's use of vfork() due to the complexity of using it properly and potential directions that Linux platforms where it defaults to on could take, this adds a failsafe so that users can disable its use entirely by setting a global flag. No known reason to disable it exists. But it'd be a shame to encounter one and not be able to use CPython without patching and rebuilding it. See the linked issue for some discussion on reasoning. Also documents the existing way to disable posix_spawn.

| | | | | | test_capi.test_export_symbols() doesn't check if Python exports the "PyThread_get_thread_native_id" symbol if the _thread.get_native_id() function is not available (if the PY_HAVE_THREAD_NATIVE_ID macro is not defined).
* bpo-44133: Link Python executable with object files (GH-30556)Victor Stinner2022-01-131-0/+18
| | | | | | | | | | | | | | When Python is built without --enable-shared, the "python" program is now linked to object files, rather than being linked to the Python library (libpython.a), to make sure that all symbols are exported. Previously, the linker omitted some symbols like the Py_FrozenMain() function. When Python is configured with --without-static-libpython, the Python static library (libpython.a) is no longer built. * Check --without-static-libpython earlier in configure.ac * Add LINK_PYTHON_OBJS and LINK_PYTHON_DEPS variables to Makefile. * test_capi now ensures that the "Py_FrozenMain" symbol is exported.

* 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...).
