Fix building the _testcapi extension on Linux armv6a which requires linking to libatomic when <cpython/pyatomic.h> is used: the _Py_atomic_or_uint8() function requires libatomic __atomic_fetch_or_8() on this platform.

The configure script now checks if linking to libatomic is needed and generates a new LIBATOMIC variable used to build the _testcapi extension.

Building the _testcapi extension now uses the LIBATOMIC variable in its LDFLAGS, since Modules/_testcapi/pyatomic.c uses <cpython/pyatomic.h>.

Command to test this PR:

$ git clean -fdx; ./configure --with-pydebug; echo; echo; grep -E '^(LIBS|LIBATOMIC)' Makefile; grep '_TESTCAPI_.*=' Makefile

Output on Linux x86-64:

LIBS=		-ldl 
LIBATOMIC=	
LIBSUBDIRS=	asyncio \
MODULE__TESTCAPI_STATE=yes
MODULE__TESTCAPI_LDFLAGS=
MODULE__TESTCAPI_DEPS=$(srcdir)/Modules/_testcapi/testcapi_long.h $(srcdir)/Modules/_testcapi/parts.h $(srcdir)/Modules/_testcapi/util.h

Well, libatomic is not needed to implement _Py_atomic_or_uint8() on x86-64 (using gcc (GCC) 13.2.1 20230728 (Red Hat 13.2.1-1)).

pyatomic.h has multiple implementations depending on the C compiler, the CPU architecture and the platform:

#if _Py_USE_GCC_BUILTIN_ATOMICS
#  define Py_ATOMIC_GCC_H
#  include "cpython/pyatomic_gcc.h"
#  undef Py_ATOMIC_GCC_H
#elif __STDC_VERSION__ >= 201112L && !defined(__STDC_NO_ATOMICS__)
#  define Py_ATOMIC_STD_H
#  include "cpython/pyatomic_std.h"
#  undef Py_ATOMIC_STD_H
#elif defined(_MSC_VER)
#  define Py_ATOMIC_MSC_H
#  include "cpython/pyatomic_msc.h"
#  undef Py_ATOMIC_MSC_H
#else
#  error "no available pyatomic implementation for this platform/compiler"
#endif

My change doesn't work. Apparently I picked the wrong function for the configure test. I made the assumption that __atomic_fetch_or_8() is related _Py_atomic_or_uint8().

checking whether libatomic is needed by <pyatomic.h>... no

I don't think this is needed; since we only need this for _testcapi, you'll be fine with MODULE__TESTCAPI_LDFLAGS (it is set automatically via PY_STDLIB_MOD in configure.ac.

Shortly, LIBATOMIC will be needed by more code. I'm pretty sure that @colesbury will use <cpython/pyatomic.h> in a few more C files :-D

Moreover, I'm trying to generate MODULE__TESTCAPI_LDFLAGS=$(LIBATOMIC) in the Makefile. So after configure, it would remind possible to "fix" LIBATOMIC once for all object files which use the variable.

But I failed to fail a syntax to generate this line, configure strongly wants to replace LIBATOMIC variable with its value :-)

I think this should be done in configure.ac. If it is needed by other extension modules, we add it to their PY_STDLIB_MOD. If it is needed by everything (a global linker option), we can use one of the LDFLAGS variables that are already in place :)

I updated my PR:

  • Replace _Py_atomic_or_uint8() with _Py_atomic_or_uint64(): it seems like _Py_atomic_or_uint64() is the function which pulls __atomic_fetch_or_8().
  • Remove AC_MSG_RESULT([XXX add -latomic to LIBS... too late?]) debug message

Since we only need this for _testcapi now, I suggest to only use the PY_STDLIB_MOD machinery in configure.ac. If we need to expand its use, we can do that in a follow-up PR. Restricting this to _testcapi makes for a less invasive change:

Ok, with my update, my PR works as expected to fix building the _testcapi extension on the Raspbian buildbot worker.*

configure:

checking whether libatomic is needed by <pyatomic.h>... yes

make uses -latomic:

I modified my PR to generate MODULE__TESTCAPI_LDFLAGS=$(LIBATOMIC) in the Makefile, so it's possible to override LIBATOMIC when running make, or even by modifying Makefile manually.

I made the same change for LIBM.

Before, you had to modify all variables using LIBATOMIC and LIBM to update them as well.

Concrete example on my Linux x86-64, to force linking to libatomic even if configure decided that nope, testcapi doesn't need it:

$ make LIBATOMIC=-latomic 2>&1|tee log
gcc -shared      Modules/_testcapimodule.o (...) -latomic  -o Modules/_testcapi.cpython-313d-x86_64-linux-gnu.so

$ ldd Modules/_testcapi.cpython-313d-x86_64-linux-gnu.so|grep atomic
	libatomic.so.1 => /lib64/libatomic.so.1 (0x00007ff2c7b98000)

The _testcapi extension is linked explicitly to libatomic as expected.

See my previous comment, IMO it's useful to allow overriding LIBATOMIC. In my experience, build systems are not smart enough and they should give back some flexibility to users. As @colesbury shown, libatomic may be optional depending on GCC flags, and GCC flags can be overriden when running make.

Also, you can expect that shortly, LIBATOMIC will be needed in more Python extensions, and Python itself. This PR prepares that.

See my previous comment, IMO it's useful to allow overriding LIBATOMIC. In my experience, build systems are not smart enough and they should give back some flexibility to users.

I agree, but I think that flexibility should be in configure, and not Makefile. We provide a lot of such customisation options in configure.ac already (check ./configure --help | grep ). Very few of these can be overridden in the Makefile. I agree we should provide the flexibility, but I think it should stay in configure, for consistency :)

It seems like LIBATOMIC cannot be overriden with my latest change, I don't see it in configure help. I suppose that we can enhance configure later if needed.

What do you mean? Creating variables is not needed in configure.ac? I prefer to be explicit and declare it to an empty string.

Oh, LIBATOMIC=${LIBATOMIC-"-latomic"} does nothing if LIBATOMIC is already defined (to an empty string). So I removed it.

I just realised we could probably just use ${VAR="default"} instead of the more verbose VAR=${VAR-"default"}. However, let's stick to the existing practise :) And hopefully, configure.ac is git rm'd some day.

⚠️⚠️⚠️ Buildbot failure ⚠️⚠️⚠️

Hi! The buildbot wasm32-emscripten node (pthreads) 3.x has failed when building commit 1f7e421.

What do you need to do:

  1. Don't panic.
  2. Check the buildbot page in the devguide if you don't know what the buildbots are or how they work.
  3. Go to the page of the buildbot that failed (https://buildbot.python.org/all/#builders/1050/builds/2996) and take a look at the build logs.
  4. Check if the failure is related to this commit (1f7e421) or if it is a false positive.
  5. If the failure is related to this commit, please, reflect that on the issue and make a new Pull Request with a fix.

You can take a look at the buildbot page here:

https://buildbot.python.org/all/#builders/1050/builds/2996

 * branch                  main       -> FETCH_HEAD
Note: switching to '1f7e42131d2800f0fbb89bfd91fafa8a073e066d'.

You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by switching back to a branch.

If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -c with the switch command. Example:

  git switch -c <new-branch-name>

Or undo this operation with:

  git switch -

Turn off this advice by setting config variable advice.detachedHead to false

HEAD is now at 1f7e42131d gh-109054: configure checks if libatomic is needed (#109101)
Switched to and reset branch 'main'

⚠️⚠️⚠️ Buildbot failure ⚠️⚠️⚠️

Hi! The buildbot aarch64 Fedora Stable LTO 3.x has failed when building commit 1f7e421.

What do you need to do:

  1. Don't panic.
  2. Check the buildbot page in the devguide if you don't know what the buildbots are or how they work.
  3. Go to the page of the buildbot that failed (https://buildbot.python.org/all/#builders/336/builds/3939) and take a look at the build logs.
  4. Check if the failure is related to this commit (1f7e421) or if it is a false positive.
  5. If the failure is related to this commit, please, reflect that on the issue and make a new Pull Request with a fix.

You can take a look at the buildbot page here:

https://buildbot.python.org/all/#builders/336/builds/3939

aarch64 Fedora Stable LTO 3.x has failed

Minor unrelated issue: 1 test altered the execution environment: test_interpreters.

wasm32-emscripten node (dynamic linking) 3.x has failed
wasm32-emscripten node (pthreads) 3.x has failed

Not good. "Compile host Python" failed with:

checking whether libatomic is needed by <pyatomic.h>... yes

wasm-ld: error: unable to find library -latomic

I wrote PR #109211 to fix building Python with cross-compilation (wasm32 buildbots).
