From fbe2a1394bf52f5a4455681e1b1f705a31559585 Mon Sep 17 00:00:00 2001 From: "Miss Islington (bot)" <31488909+miss-islington@users.noreply.github.com> Date: Mon, 29 Apr 2019 12:56:58 -0700 Subject: bpo-34602: Avoid failures setting macOS stack resource limit (GH-13011) (GH-13014) Under some conditions the earlier fix for bpo-18075, "Infinite recursion tests triggering a segfault on Mac OS X", now causes failures on macOS when attempting to change stack limit with resource.setrlimit resource.RLIMIT_STACK, like regrtest does when running the test suite. The reverted change had specified a non-default stack size when linking the python executable on macOS. As of macOS 10.14.4, the previous code causes a hard failure when running tests, although similar failures had been seen under some conditions under some earlier systems. For now, revert the original change and resume using the default stack size when linking the interpreter. (cherry picked from commit 883dfc668f9730b00928730035b5dbd24b9da2a0) Co-authored-by: Ned Deily --- Misc/NEWS.d/next/macOS/2019-04-29-10-54-14.bpo-34602.Lrl2zU.rst | 3 +++ configure | 6 ------ configure.ac | 6 ------ 3 files changed, 3 insertions(+), 12 deletions(-) create mode 100644 Misc/NEWS.d/next/macOS/2019-04-29-10-54-14.bpo-34602.Lrl2zU.rst diff --git a/Misc/NEWS.d/next/macOS/2019-04-29-10-54-14.bpo-34602.Lrl2zU.rst b/Misc/NEWS.d/next/macOS/2019-04-29-10-54-14.bpo-34602.Lrl2zU.rst new file mode 100644 index 0000000000..6f7ac881c8 --- /dev/null +++ b/Misc/NEWS.d/next/macOS/2019-04-29-10-54-14.bpo-34602.Lrl2zU.rst @@ -0,0 +1,3 @@ +Avoid failures setting macOS stack resource limit with resource.setrlimit. +This reverts an earlier fix for bpo-18075 which forced a non-default stack +size when building the interpreter executable on macOS. diff --git a/configure b/configure index e39c16eee2..634e18af4e 100755 --- a/configure +++ b/configure @@ -9504,12 +9504,6 @@ then # -u libsys_s pulls in all symbols in libsys Darwin/*) LINKFORSHARED="$extra_undefs -framework CoreFoundation" - - # Issue #18075: the default maximum stack size (8MBytes) is too - # small for the default recursion limit.
