default stack size for threads is approx 140k on musl which is fine in most cases but some of python apps e.g. python3-lz4 bindings run into thread stack size overflow. Increase the default size to 2M on musl, glibc defaults to 8M, so we are good there.
This default stack size change is limited to interpreter and stdlib modules only, thats why CFLAGS_NODIST instead of CFLAGS Signed-off-by: Khem Raj <[email protected]> --- meta/recipes-devtools/python/python3_3.11.4.bb | 7 +++++++ 1 file changed, 7 insertions(+) diff --git a/meta/recipes-devtools/python/python3_3.11.4.bb b/meta/recipes-devtools/python/python3_3.11.4.bb index 8fd1382caa4..ac4c6221ca3 100644 --- a/meta/recipes-devtools/python/python3_3.11.4.bb +++ b/meta/recipes-devtools/python/python3_3.11.4.bb @@ -91,6 +91,13 @@ CACHED_CONFIGUREVARS = " \ ac_cv_file__dev_ptc=no \ ac_cv_working_tzset=yes \ " +# set thread stack size to 2MB on musl for interpreter and stdlib C extensions +# so it does not run into stack limits due to musl's small thread stack +# This is only needed to build interpreter and not the subsequent modules +# Thats why CFLAGS_NODIST is modified instead of CFLAGS +CACHED_CONFIGUREVARS:append:libc-musl = "\ + CFLAGS_NODIST='${CFLAGS} -DTHREAD_STACK_SIZE=0x200000' \ +" # PGO currently causes builds to not be reproducible so disable by default, see YOCTO #13407 PACKAGECONFIG ??= "editline gdbm ${@bb.utils.filter('DISTRO_FEATURES', 'lto', d)}" -- 2.42.0
