PPC64LE Fedora Stable Clang 3.x fails test_gdb #104736

JelleZijlstra · 2023-05-22T05:06:37Z

Buildbot https://buildbot.python.org/all/#/builders/435 has been failing test_gdb with errors like these:

======================================================================

It last succeeded on commit 373bca0 and first failed on fcd5fb4, suggesting that the culprit is one of these commits:

fcd5fb4 Comprehension inlining: Bug if comprehension contains a lambda #104357: fix inlined comprehensions that close over iteration var (gh-104357: fix inlined comprehensions that close over iteration var #104368)

Neither looks likely to affect test_gdb though.

It looks like GDB can't extract the C stack here. I SSHd to the buildbot and tried:

$ gdb --args ./python -c 'import _testcapi; _testcapi.meth_varargs()'
[...]

Backtrace stopped: frame did not save the PC

The stack looks corrupted: PyModuleDef_Type is data, not a function.
This looks like “miscommunication” between clang and gdb (bad debug info?)

The test seems very sensitive to platform/compiler, e.g.:

if 'Clang' in platform.python_compiler() and sys.platform == 'darwin':
    raise unittest.SkipTest("test_gdb doesn't work correctly when python is"
                            " built with LLVM clang")

Note that the “installed” buildbots are green. (AFAIK these test Python after make install.) But when I make install, GDB still fails to extract the backtrace on the installed Python.

See #65462 (comment):

Unless someone has a better idea, I suggest we just disable test_gdb on OS X or, somewhat more precisely, when Python has been compiled with LLVM clang.

Doesn't clang always use LLVM?
The skip is now 'Clang' in platform.python_compiler() and sys.platform == 'darwin', should it just be 'Clang' in platform.python_compiler()?

stratakis · 2023-05-22T14:45:24Z

The failure started after the update of Clang to 16.0.0 from 15.0.7.

I took it to mean "not Apple's Clang" which is distinct (has its own versioning and is essentially a fork). I might be wrong here though.

vstinner · 2023-05-23T07:39:05Z

Maybe tets_gdb can skip a test if "frame did not save the PC" is found in the output. We already have many skips like that.

carljm · 2023-08-30T20:58:12Z

It looks like multiple Clang buildbots are still failing test_gdb.

I closed issue #109053 as a duplicate of this issue.

vstinner · 2023-09-13T03:01:33Z

I did tests on two ppc64le machines. In short, test_gdb only failed on ppc64le if Python is built with clang version 16.0.6 (clang -Og). Well, that's what we saw on buildbots. But I preferred to confirm manually. I built Python manually and ran test_gdb manually with -u all to no skip any test.

Here, I think that the important part is #1 0x0000000000000000 in ?? (). When gdb says that, usually it's likely that the traceback is truncated or wrong.

Issue fixed by commit 44d9a71 the main branch. The backport commits will follow soon. Thanks for the bug report.

@encukou:

This looks like “miscommunication” between clang and gdb (bad debug info?)

I suppose that lldb has a way better support for clang. It's possible to script lldb in Python! I found this cpython-lldb project: "LLDB extension for debugging Python programs."

The skip is now 'Clang' in platform.python_compiler() and sys.platform == 'darwin', should it just be 'Clang' in platform.python_compiler()?

When possible, I'm trying to skip the least number of tests. With my PR #108999 fixing test_gdb on FreeBSD with clang, in fact, many tests are still run on FreeBSD/clang.

In verbose mode, these "pycfunction" tests now log each tested call. * test_pycfunction_noargs() * test_pycfunction_o() * test_pycfunction_varargs() * test_pycfunction_varargs_keywords() * test_pycfunction_fastcall() * test_pycfunction_fastcall_keywords() * Move get_gdb_repr() to PrettyPrintTests. * Replace DebuggerTests.get_sample_script() with SAMPLE_SCRIPT. * Rename checkout_hook_path to CHECKOUT_HOOK_PATH. * Rename gdb_version to GDB_VERSION_TEXT. * Replace (gdb_major_version, gdb_minor_version) with GDB_VERSION. * run_gdb() uses "backslashreplace" error handler instead of "replace". * Add check_gdb() function to util.py. * Enhance support.check_cflags_pgo(): check also for sysconfig PGO_PROF_USE_FLAG (if available) in compiler flags. * Move some SkipTest checks to test_gdb/__init__.py. * Elaborate why gdb cannot be tested on Windows: gdb doesn't support PDB debug symbol files. (cherry picked from commit 757cbd4) * gh-104736: Fix test_gdb tests on ppc64le with clang (GH-109360) Fix test_gdb on Python built with LLVM clang 16 on Linux ppc64le (ex: Fedora 38). Search patterns in gdb "bt" command output to detect when gdb fails to retrieve the traceback. For example, skip a test if "Backtrace stopped: frame did not save the PC" is found. (cherry picked from commit 44d9a71) * gh-110166: Fix gdb CFunctionFullTests on ppc64le clang build (GH-110331) CFunctionFullTests now also runs "bt" command before "py-bt-full", similar to CFunctionTests which also runs "bt" command before "py-bt". So test_gdb can skip the test if patterns like "?? ()" are found in the gdb output. (cherry picked from commit bbce8bd) Co-authored-by: Victor Stinner <vstinner@python.org> (cherry picked from commit 1de9406) Co-authored-by: Victor Stinner <vstinner@python.org>
