* [3.13] gh-113993: Allow interned strings to be mortal, and fix related ↵Petr Viktorin2024-06-241-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | issues (GH-120520) (GH-120945) * Add an InternalDocs file describing how interning should work and how to use it. * Add internal functions to *explicitly* request what kind of interning is done: - `_PyUnicode_InternMortal` - `_PyUnicode_InternImmortal` - `_PyUnicode_InternStatic` * Switch uses of `PyUnicode_InternInPlace` to those. * Disallow using `_Py_SetImmortal` on strings directly. You should use `_PyUnicode_InternImmortal` instead: - Strings should be interned before immortalization, otherwise you're possibly interning a immortalizing copy. - `_Py_SetImmortal` doesn't handle the `SSTATE_INTERNED_MORTAL` to `SSTATE_INTERNED_IMMORTAL` update, and those flags can't be changed in backports, as they are now part of public API and version-specific ABI. * Add private `_only_immortal` argument for `sys.getunicodeinternedsize`, used in refleak test machinery. * Make sure the statically allocated string singletons are unique. This means these sets are now disjoint: - `_Py_ID` - `_Py_STR` (including the empty string) - one-character latin-1 singletons Now, when you intern a singleton, that exact singleton will be interned. * Add a `_Py_LATIN1_CHR` macro, use it instead of `_Py_ID`/`_Py_STR` for one-character latin-1 singletons everywhere (including Clinic). * Intern `_Py_STR` singletons at startup. * For free-threaded builds, intern `_Py_LATIN1_CHR` singletons at startup. * Beef up the tests. Cover internal details (marked with `@cpython_only`). * Add lots of assertions Co-authored-by: Eric Snow <ericsnowcurrently@gmail.com>

* bpo-35081: Move accu.h to Include/internal/pycore_accu.h (GH-10271)Victor Stinner2018-11-011-1/+1
| | | | | | | The accu.h header is no longer part of the Python C API: it has been moved to the "internal" headers which are restricted to Python itself. Replace #include "accu.h" with #include "pycore_accu.h".
* bpo-25862: Fix several bugs in the _io module. (GH-8026)Serhiy Storchaka2018-06-301-1/+3
| | | | | | | | | | | They can be exposed when some C API calls fail due to lack of memory. * Failed Py_BuildValue() could cause an assertion error in the following TextIOWrapper.tell(). * input_chunk could be decrefed twice in TextIOWrapper.seek() after failed Py_BuildValue(). * initvalue could leak in StringIO.__getstate__() after failed PyDict_Copy().
* bpo-33012: Fix invalid function cast warnings with gcc 8 for METH_NOARGS. ↵Siddhesh Poyarekar2018-04-291-1/+1
| | | | | | | | | (GH-6030) METH_NOARGS functions need only a single argument but they are cast into a PyCFunction, which takes two arguments. This triggers an invalid function cast warning in gcc8 due to the argument mismatch. Fix this by adding a dummy unused argument.
