* Add context manager on Bunch class.
* Bunch now catchs exceptions on executed functions and re-raise them
at __exit__() as an ExceptionGroup.
* Rewrite BarrierProxy.test_default_timeout(). Use a single thread.
Only check that barrier.wait() blocks for at least default timeout
seconds.
* test_with(): inline _with() function.
Fix test_asyncio timeouts: don't measure the maximum duration, a test
should not measure a CI performance. Only measure the minimum
duration when a task has a timeout or delay. Add CLOCK_RES to
test_asyncio.utils.
In the subprocess code path, wait until the child process completes
with a timeout of EXIT_TIMEOUT seconds.
Fix create_worker_process() regression: use start_new_session=True if
USE_PROCESS_GROUP is true.
WorkerThread.wait_stopped() uses a timeout of 60 seconds, instead of
30 seconds.
On Windows, multiprocessing Popen.terminate() now catchs
PermissionError and get the process exit code. If the process is
still running, raise again the PermissionError. Otherwise, the
process terminated as expected: store its exit code.
Fix race conditions in test_threading lock tests. Wait until a
condition is met rather than using time.sleep() with a hardcoded
number of seconds.
* Replace sleeping loops with support.sleeping_retry() which raises
an exception on timeout.
* Add wait_threads_blocked(nthread) which computes a sleep depending
on the number of threads. Remove _wait() function.
* test_set_and_clear(): use a way longer Event.wait() timeout.
* BarrierTests.test_repr(): wait until the 2 threads are waiting for
the barrier. Use a way longer timeout for Barrier.wait() timeout.
* test_thread_leak() no longer needs to count
len(threading.enumerate()): Bunch uses
threading_helper.wait_threads_exit() internally which does it in
wait_for_finished().
* Add BaseLockTests.wait_phase() which implements a timeout.
test_reacquire() and test_recursion_count() use wait_phase().
In 2003, test_pty got a hardcoded timeout of 10 seconds to prevent
hanging on AIX & HPUX "if run after test_openpty":
commit 7d8145268e. Since 2003, test_pty
was no longer reported to hang on AIX. But today, the test can fail
simply because a CI is busy running other tests in parallel.
The timeout of 10 seconds is no longer needed, just remove it.
Moreover, regrtest now has multiple built-in generic timeout
mecanisms.
Fix test_interprocess_signal() of test_signal. Make sure that the
subprocess.Popen object is deleted before the test raising an
exception in a signal handler. Otherwise, Popen.__del__() can get the
exception which is logged as "Exception ignored in: ...." and the
test fails.
* 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.
Fix test_timeout() of test_concurrent_futures.test_wait. Remove the
future which may or may not complete depending if it takes longer
than the timeout ot not. Keep the second future which does not
complete before wait(). Make also the test faster: 0.5 second instead
of 6 seconds, so remove @support.requires_resource('walltime')
decorator.
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().
These are the most popular specializations of `LOAD_ATTR` and `STORE_ATTR`
that weren't already viable uops:
* Split LOAD_ATTR_METHOD_WITH_VALUES
* Split LOAD_ATTR_METHOD_NO_DICT
* Split LOAD_ATTR_SLOT
* Split STORE_ATTR_SLOT
* Split STORE_ATTR_INSTANCE_VALUE
Also:
* Add `-v` flag to code generator which prints a list of non-viable uops
(easter-egg: it can print execution counts -- see source)
* Double _Py_UOP_MAX_TRACE_LENGTH to 128
I had dropped one of the DEOPT_IF() calls! :-(
As discussed in comments to #109544, the semantics of this attribute
are somewhat confusing. Add a note explaining its limitations and
steering users towards __required_keys__ and __optional_keys__ instead.
Fix the test when run on an installed Python: use "abs_srcdir" of
sysconfig, and skip the test if the Python source code cannot be
found.
* Tools/patchcheck/patchcheck.py, Tools/freeze/test/freeze.py and
Lib/test/libregrtest/utils.py now first try to get "abs_srcdir"
from sysconfig, before getting "srcdir" from sysconfig.
* test.pythoninfo logs sysconfig "abs_srcdir".
WASM and WASI buildbots use multiple PYTHON environment variables
such as PYTHONPATH and _PYTHON_HOSTRUNNER. Don't use -E if the
--python=COMMAND option is used.
