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.
Fix copy_source_tree() function of test_tools.test_freeze:
* Don't copy SRC_DIR/build/ anymore. This directory is modified by
other tests running in parallel.
* Add test.support.copy_python_src_ignore().
* Use sysconfig to get the source directory.
* Use sysconfig.get_config_var() to get CONFIG_ARGS variable.
* On Windows, use subprocess.run() instead of os.execv().
* Only add needed options
* Rename reexec parameter to _add_python_opts.
* Rename --no-reexec option to --dont-add-python-opts.
Remove replace_stdout(): call sys.stdout.reconfigure() instead of set
the error handler to backslashreplace.
display_header() logs an empty line and flush stdout.
Remove encoding workaround in display_header() since stdout error
handler is now set to backslashreplace earlier.
When --fast-ci or --slow-ci option is used, regrtest now replaces the
current process with a new process to add "-u -W default -bb -E"
options to Python.
Changes:
* PCbuild/rt.bat and Tools/scripts/run_tests.py no longer need to add
"-u -W default -bb -E" options to Python: it's now done by
regrtest.
* Fix Tools/scripts/run_tests.py: flush stdout before replacing the
process. Previously, buffered messages were lost.
* Add --fast-ci and --slow-ci options to libregrtest:
* --fast-ci uses a default timeout of 10 minutes and "-u all,-cpu"
(skip slowest tests).
* --slow-ci uses a default timeout of 20 minues and "-u all" (run
all tests).
* regrtest header now lists test resources.
* Makefile changes:
* "make test", "make hostrunnertest" and "make coverage-report" now
use --fast-ci option and TESTTIMEOUT variable.
* "make buildbottest" now uses "--slow-ci". Remove options which
became redundant with "--slow-ci".
* "make testall" and "make testuniversal" now use --slow-ci option
and TESTTIMEOUT variable.
* "make testall" now uses "find -exec rm ..." instead of
"find ... -print|xargs rm ...", same as "make clean".
* GitHub Actions workflow:
* Ubuntu and Address Sanitizer jobs now use "make test". Remove
options which became redundant with "--fast-ci".
* Windows jobs now use --fast-ci option.
* Use -j0 to detect the number of CPUs.
* Set Makefile TESTTIMEOUT default to an empty string, since
--slow-ci and --fast-ci use different default timeout. It's now
accepted to pass "--timeout=" to regrtest: treated as not timeout.
* Tools/scripts/run_tests.py now uses --fast-ci option.
* Tools/buildbot/test.bat now uses --slow-ci option. Remove
--timeout=1200 option, redundant with --slow-ci.
test_error_at_task_unpickle() and
test_error_during_result_unpickle_in_result_handler() now restore
sys.stderr which is overriden by _raise_error_ignore_stderr().
Follow-up of gh-107219.
* Only close the connection writer on Windows.
* Also use existing constant _winapi.ERROR_OPERATION_ABORTED instead of
WSA_OPERATION_ABORTED.
* Refactor zipfile._strip_extra to use higher level abstractions for extras instead of a heavy-state loop.
* Add blurb
* Remove _strip_extra and use _Extra.strip directly.
* Use memoryview to avoid unnecessary copies while splitting Extras.
Fix test_zippath_from_non_installed_posix() of test_venv: don't copy
__pycache__/ sub-directories, because they can be modified by other
Python tests running in parallel.
* Factorize code listing "bad / env changed / ..." tests.
* Add TestResults.is_all_good() method.
* Move "All 400 tests OK." to the end
* Move "Test suite interrupted by signal SIGINT." to the end.
