* gh-123022: Fix crash with `Py_Initialize` in background thread (#123052)Sam Gross2024-08-174-5/+40
| | | | | | | | | | | | Check that the current default heap is initialized in `_mi_os_get_aligned_hint` and `mi_os_claim_huge_pages`. The mimalloc function `_mi_os_get_aligned_hint` assumes that there is an initialized default heap. This is true for our main thread, but not for background threads. The problematic code path is usually called during initialization (i.e., `Py_Initialize`), but it may also be called if the program allocates large amounts of memory in total. The crash only affected the free-threaded build.

* GH-120754: Disable buffering in Path.read_bytes (#122111)Cody Maloney2024-08-163-2/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | `Path.read_bytes()` is used to read a whole file. buffering / BufferedIO is focused around making small, possibly interleaved, read/write efficient which doesn't add value in this case. On my Mac, running the benchmark: ```python import pyperf from pathlib import Path def read_all(all_paths): for p in all_paths: p.read_bytes() def read_file(path_obj): path_obj.read_bytes() all_rst = list(Path("Doc").glob("**/*.rst")) all_py = list(Path(".").glob("**/*.py")) assert all_rst, "Should have found rst files" assert all_py, "Should have found python source files" runner = pyperf.Runner() runner.bench_func("read_file_small", read_file, Path("Doc/howto/clinic.rst")) runner.bench_func("read_file_large", read_file, Path("Doc/c-api/typeobj.rst")) ``` before: ```python ..................... read_file_small: Mean +- std dev: 6.80 us +- 0.07 us ..................... read_file_large: Mean +- std dev: 10.8 us +- 0.2 us ```` after: ```python ..................... read_file_small: Mean +- std dev: 5.67 us +- 0.05 us ..................... read_file_large: Mean +- std dev: 9.77 us +- 0.52 us ```
