* [3.12] gh-110995: Fix test_gdb check_usable_gdb() (GH-110998) (#111003)Miss Islington (bot)2023-10-171-6/+11
| | | | | | | | | | | | gh-110995: Fix test_gdb check_usable_gdb() (GH-110998) Fix detection of gdb built without Python scripting support. * check_usable_gdb() doesn't check gdb exit code when calling run_gdb(). * Use shutil.which() to get the path to the gdb program. (cherry picked from commit 920b3dfacad615c7bb9bd9a35774469f8809b453) Co-authored-by: Victor Stinner <vstinner@python.org>
* [3.12] gh-109972: Enhance test_gdb (#110026) (#110351)Victor Stinner2023-10-041-137/+119
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * gh-109972: Enhance test_gdb (#110026) * Split test_pycfunction.py: add test_cfunction_full.py. Split the function into the following 6 functions. 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 757cbd4f29c9e89b38b975e0463dc8ed331b2515) * gh-104736: Fix test_gdb tests on ppc64le with clang (#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 44d9a71ea246e7c3fb478d9be62c16914be6c545) * gh-110166: Fix gdb CFunctionFullTests on ppc64le clang build (#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 1de9406f9136e3952b849487f0151be3c669a3ea)
* [3.12] gh-109972: Split test_gdb.py into test_gdb package (#109977) (#110339)Victor Stinner2023-10-041-0/+304
gh-109972: Split test_gdb.py into test_gdb package (#109977) Split test_gdb.py file into a test_gdb package made of multiple tests, so tests can now be run in parallel. * Create Lib/test/test_gdb/ directory. * Split test_gdb.py into multiple files in Lib/test/test_gdb/ directory. * Move Lib/test/gdb_sample.py to Lib/test/test_gdb/ directory. Update get_sample_script(): use __file__ to locate gdb_sample.py. * Move gdb_has_frame_select() and HAS_PYUP_PYDOWN to test_misc.py. * Explicitly skip test_gdb on Windows. Previously, test_gdb was skipped even if gdb was available because of gdb_has_frame_select(). (cherry picked from commit 8f324b7ecd2df3036fab098c4c8ac185ac07b277)
