* gh-95534: Improve gzip reading speed by 10% (#97664)Ruben Vorderman2022-10-171-0/+1
| | | | | | | | | Change summary: + There is now a `gzip.READ_BUFFER_SIZE` constant that is 128KB. Other programs that read in 128KB chunks: pigz and cat. So this seems best practice among good programs. Also it is faster than 8 kb chunks. + a zlib._ZlibDecompressor was added. This is the _bz2.BZ2Decompressor ported to zlib. Since the zlib.Decompress object is better for in-memory decompression, the _ZlibDecompressor is hidden. It only makes sense in file decompression, and that is already implemented now in the gzip library. No need to bother the users with this. + The ZlibDecompressor uses the older Cpython arrange_output_buffer functions, as those are faster and more appropriate for the use case. + GzipFile.read has been optimized. There is no longer a `unconsumed_tail` member to write back to padded file. This is instead handled by the ZlibDecompressor itself, which has an internal buffer. `_add_read_data` has been inlined, as it was just two calls. EDIT: While I am adding improvements anyway, I figured I could add another one-liner optimization now to the python -m gzip application. That read chunks in io.DEFAULT_BUFFER_SIZE previously, but has been updated now to use READ_BUFFER_SIZE chunks.

| | | | | | #97530 fixed IDLE tests possibly crashing on a Mac without a GUI. But it resulted in IDLE not starting in 3.10.8, 3.12.0a1, and Microsoft Python 3.10.2288.0 when test/* is not installed. After this patch, test.* is only imported when testing on Mac.

* GH-94597: Deprecate child watcher getters and setters (#98215)Kumar Aditya2022-10-151-0/+1
| | | | | | | This is the next step for deprecating child watchers. Until we've removed the API completely we have to use it, so this PR is mostly suppressing a lot of warnings when using the API internally. Once the child watcher API is totally removed, the two child watcher implementations we actually use and need (Pidfd and Thread) will be turned into internal helpers.

* gh-98178: syslog() is not thread-safe on macOS (#98213)Victor Stinner2022-10-131-0/+4
| | | | | | On macOS, fix a crash in syslog.syslog() in multi-threaded applications. On macOS, the libc syslog() function is not thread-safe, so syslog.syslog() no longer releases the GIL to call it.

* gh-44098: Release the GIL during mmap on Unix (GH-98146)Shantanu2022-10-101-0/+1
| | | | | This seems pretty straightforward. The issue mentions other calls in mmapmodule that we could release the GIL on, but those are in methods where we'd need to be careful to ensure that something sensible happens if those are called concurrently. In prior art, note that #12073 released the GIL for munmap. In a toy benchmark, I see the speedup you'd expect from doing this. Automerge-Triggered-By: GH:gvanrossum
* gh-96821: Fix undefined behaviour in `audioop.c` (#96923)Matthias Görgens2022-10-101-0/+1
| | | | | | | | | | | * gh-96821: Fix undefined behaviour in `audioop.c` Left-shifting negative numbers is undefined behaviour. Fortunately, multiplication works just as well, is defined behaviour, and gets compiled to the same machine code as before by optimizing compilers.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | warnings.warn_explicit() (GH-97803) In `_warnings.c`, in the C equivalent of `warnings.warn_explicit()`, if the module globals are given (and not None), the warning will attempt to get the source line for the issued warning. To do this, it needs the module's loader. Previously, it would only look up `__loader__` in the module globals. In https://github.com/python/cpython/issues/86298 we want to defer to the `__spec__.loader` if available. The first step on this journey is to check that `loader == __spec__.loader` and issue another warning if it is not. This commit does that. Since this is a PoC, only manual testing for now. ```python # /tmp/foo.py import warnings import bar warnings.warn_explicit( 'warning!', RuntimeWarning, 'bar.py', 2, module='bar knee', module_globals=bar.__dict__, ) ``` ```python # /tmp/bar.py import sys import os import pathlib # __loader__ = pathlib.Path() ``` Then running this: `./python.exe -Wdefault /tmp/foo.py` Produces: ``` bar.py:2: RuntimeWarning: warning! import os ``` Uncomment the `__loader__ = ` line in `bar.py` and try it again: ``` sys:1: ImportWarning: Module bar; __loader__ != __spec__.loader (<_frozen_importlib_external.SourceFileLoader object at 0x109f7dfa0> != PosixPath('.')) bar.py:2: RuntimeWarning: warning! import os ``` Automerge-Triggered-By: GH:warsaw

| | | | | | | | | This is a small performance improvement, especially for one or two hot places such as _handle_fromlist() that are called a lot and the .format() method was being used just to join two strings with a dot. Otherwise it is merely a readability improvement. We keep `_ERR_MSG` and `_ERR_MSG_PREFIX` as those may be used elsewhere for canonical looking error messages.

| | | | | | | | The macOS 13 SDK includes support for the `mkfifoat` and `mknodat` system calls. Using the `dir_fd` option with either `os.mkfifo` or `os.mknod` could result in a segfault if cpython is built with the macOS 13 SDK but run on an earlier version of macOS. Prevent this by adding runtime support for detection of these system calls ("weaklinking") as is done for other newer syscalls on macOS.
