GCC complains:
Python/pylifecycle.c: In function ‘_Py_InitializeFromConfig’:
Python/pylifecycle.c:900:13: warning: ‘interp’ may be used uninitialized in this function [-Wmaybe-uninitialized]
err = _Py_InitializeMainInterpreter(interp, &main_config);
~~~~^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
This seems spurious since &interp is passed to _Py_InitializeCore. Anyway, we
can easily initialize to quiet the warning.
Previously, col_offset points to the keyword after "async".
The recursive frame pruning code always undercounted the number of elided frames by one. That is, in the "[Previous line repeated N more times]" message, N would always be one too few. Near the recursive pruning cutoff, one frame could be silently dropped. That situation is demonstrated in the OP of the bug report. The fix is to start the identical frame counter at 1.
bpo-34544: If _Py_CoerceLegacyLocale() fails to coerce the C locale, restore the LC_CTYPE locale to the its previous value.
* A pointer in `PyInterpreterState_New()` could have been `NULL` when being dereferenced. * Memory was leaked in `PyInterpreterState_New()` when taking some error-handling code path.
Use the core configuration of the interpreter, rather than using global configuration variables. For example, replace Py_QuietFlag with core_config->quiet.
* Py_FileSystemDefaultEncoding and Py_FileSystemDefaultEncodeErrors default value is now NULL: initfsencoding() set them during Python initialization. * Document how Python chooses the filesystem encoding and error handler. * Add an assertion to _PyCoreConfig_Read().
PYTHONCOERCELOCALE=warn warning is now emitted later and written into sys.stderr, rather than being written into the C stderr stream.
