From d16856960e33bc5f64fc5b842f132058becafa37 Mon Sep 17 00:00:00 2001 From: Petr Viktorin Date: Tue, 25 May 2021 13:42:03 +0200 Subject: bpo-43795: Remove Py_FrozenMain from the Limited API & Stable ABI (GH-26241) Py_FrozenMain was added to the Limited C API in [bpo-42591]() (3.10.0a4); but to fix that issue it would be enough to add it to the regular C API. The function is undocumented, tests were added very recently ([bpo-44131]()), and most importantly, it is not present in all builds of Python, as the linker sometimes omits it as unused. It should be added back when these issues are fixed. Note that this does not affect Python's regular C API. --- Doc/data/stable_abi.dat | 1 - Doc/whatsnew/3.10.rst | 4 ++++ Include/cpython/pylifecycle.h | 4 ++++ Include/pylifecycle.h | 3 --- Misc/NEWS.d/next/C API/2021-05-19-15-09-47.bpo-43795.WAHRxt.rst | 1 + Misc/stable_abi.txt | 2 -- PC/python3dll.c | 1 - 7 files changed, 9 insertions(+), 7 deletions(-) create mode 100644 Misc/NEWS.d/next/C API/2021-05-19-15-09-47.bpo-43795.WAHRxt.rst diff --git a/Doc/data/stable_abi.dat b/Doc/data/stable_abi.dat index d582204..50207ac 100644 --- a/Doc/data/stable_abi.dat +++ b/Doc/data/stable_abi.dat @@ -783,7 +783,6 @@ var,Py_FileSystemDefaultEncodeErrors,3.10, var,Py_FileSystemDefaultEncoding,3.2, function,Py_Finalize,3.2, function,Py_FinalizeEx,3.6, -function,Py_FrozenMain,3.10, function,Py_GenericAlias,3.9, function,Py_GenericAliasType,3.9, function,Py_GetBuildInfo,3.2, diff --git a/Doc/whatsnew/3.10.rst b/Doc/whatsnew/3.10.rst index a006eb4..233ee8b 100644 --- a/Doc/whatsnew/3.10.rst +++ b/Doc/whatsnew/3.10.rst @@ -1927,6 +1927,10 @@ Porting to Python 3.10 instead.
