Don't spawn more threads than the number of jobs: these worker
threads would never get anything to do.
* Add the number of tests in "Run ... tests in ..." message.
* Add RunTests.get_jobs() method.
* Add plural() function.
* count() uses f-string.
libregrtest now calls random.seed() before running each test file
when -r/--randomize command line option is used. Moreover, it's also
called in worker processes. It should help to make tests more
deterministic. Previously, it was only called once in the main
process before running all test files and it was not called in worker
processes.
* Convert some f-strings to regular strings in test_regrtest when
f-string is not needed.
* Remove unused all_methods variable from test_regrtest.
* Add RunTests members are now mandatory.
On Windows, skip the test if the current working directory and the
Python source code directory have different mount drives. It happens
if the temporary directory is on a different mount drive than the
Python source code.
Fix test_os.test_access_denied() when the TEMP environment variable
is equal to the current working directory. Run the test using a
different filename, since self.fname already exists in this case.
test_asyncio and test_compileall now clean up multiprocessing by
calling multiprocessing _cleanup_tests(): explicitly clean up
resources and stop background processes like the resource tracker.
* Rename SAVE_IP to _SET_IP
* Rename EXIT_TRACE to _EXIT_TRACE
* Rename SAVE_CURRENT_IP to _SAVE_CURRENT_IP
* Rename INSERT to _INSERT (This is for Ken Jin's abstract interpreter)
* Rename IS_NONE to _IS_NONE
* Rename JUMP_TO_TOP to _JUMP_TO_TOP
This adds a 16-bit inline cache entry to the conditional branch instructions POP_JUMP_IF_{FALSE,TRUE,NONE,NOT_NONE} and their instrumented variants, which is used to keep track of the branch direction.
Each time we encounter these instructions we shift the cache entry left by one and set the bottom bit to whether we jumped.
Then when it's time to translate such a branch to Tier 2 uops, we use the bit count from the cache entry to decided whether to continue translating the "didn't jump" branch or the "jumped" branch.
The counter is initialized to a pattern of alternating ones and zeros to avoid bias.
The .pyc file magic number is updated. There's a new test, some fixes for existing tests, and a few miscellaneous cleanups.
libregrtest now uses a separated file descriptor to write test result
as JSON. Previously, if a test wrote debug messages late around the
JSON, the main test process failed to parse JSON.
Rename TestResult.write_json() to TestResult.write_json_into().
worker_process() no longer writes an empty line at the end. There is
no need to separate test process output from the JSON output anymore,
since JSON is now written into a separated file descriptor.
create_worker_process() now always spawn the process with
close_fds=True.
* Rename runtest_mp.py to run_workers.py
* Move exit_timeout() and temp_cwd() context managers from
Regrtest.main() to Regrtest.run_tests(). Actions like --list-tests
or --list-cases don't need these protections.
* Regrtest: remove selected and tests attributes. Pass 'selected' to
list_tests(), list_cases() and run_tests(). display_result() now
expects a TestTuple, instead of TestList.
* Rename setup_tests() to setup_process() and rename setup_support()
to setup_tests().
* Move _adjust_resource_limits() to utils and rename it to
adjust_rlimit_nofile().
* Move replace_stdout() to utils.
* Fix RunTests.verbose type: it's an int.
* Pass results, quiet and pgo to Logger constructor.
* Move display_progress() method from Regrtest to Logger.
* No longer pass Regrtest to RunWorkers, but logger and results.
* Add single.py and result.py files.
* Rename runtest.py to runtests.py.
* Move run_single_test() function and its helper functions to
single.py.
* Move remove_testfn(), abs_module_name() and normalize_test_name()
to utils.py.
* Move setup_support() to setup.py.
* Move type hints like TestName to utils.py.
* Rename runtest.py to runtests.py.
Add new worker.py file:
* Move create_worker_process() and worker_process() to this file.
* Add main() function to worker.py. create_worker_process() now
runs the command: "python -m test.libregrtest.worker JSON".
* create_worker_process() now starts the worker process in the
current working directory. Regrtest now gets the absolute path of
the reflog.txt filename: -R command line option filename.
* Remove --worker-json command line option.
Remove test_regrtest.test_worker_json().
Related changes:
* Add write_json() and from_json() methods to TestResult.
* Rename select_temp_dir() to get_temp_dir() and move it to utils.
* Rename make_temp_dir() to get_work_dir() and move it to utils.
It no longer calls os.makedirs(): Regrtest.main() now calls it.
* Move fix_umask() to utils. The function is now called by
setup_tests().
* Move StrPath to utils.
* Add exit_timeout() context manager to utils.
* RunTests: Replace junit_filename (StrPath) with use_junit (bool).
Fix test_pyexpat.test_exception(): it can now be run from a directory
different than Python source code directory. Before, the test failed
in this case.
Skip the test if Modules/pyexpat.c source is not available. Skip also
the test on Python implementations other than CPython.
Fix test_site.test_underpth_basic() when the working directory
contains at least one non-ASCII character: encode the "._pth" file to
UTF-8 and enable the UTF-8 Mode to use UTF-8 for the child process
stdout.
Attempts to pickle or create a shallow or deep copy of codecs streams
now raise a TypeError.
Previously, copying failed with a RecursionError, while pickling
produced wrong results that eventually caused unpickling to fail with
a RecursionError.
* Add attributes to Regrtest and RunTests:
* fail_env_changed
* num_workers
* Rename MultiprocessTestRunner to RunWorkers. Add num_workers
parameters to RunWorkers constructor. Remove RunWorkers.ns
attribute.
* Rename TestWorkerProcess to WorkerThread.
* get_running() now returns a string like: "running (...): ...".
* Regrtest.action_run_tests() now selects the number of worker
processes, instead of the command line parser.
* Add attributes to Regrtest and RunTests:
* gc_threshold
* memory_limit
* python_cmd
* use_resources
* Remove WorkerJob class. Add as_json() and from_json() methods to
RunTests. A worker process now only uses RunTests for all
parameters.
* Add tests on support.set_memlimit() in test_support. Create
_parse_memlimit() and also adds tests on it.
* Remove 'ns' parameter from runtest.py.
* Rename dash_R() runtest_refleak(). The function now gets
huntrleaks and quiet arguments, instead of 'ns' argument.
* Add attributes to Regrtest and RunTests:
* verbose
* quiet
* huntrleaks
* test_dir
* Add HuntRefleak class.
Refator Regrtest class:
* Rename finalize() finalize_tests().
* Pass tracer to run_test() and finalize_tests(). Remove Regrtest.tracer.
* run_test() does less things: move code to its caller.
* Regrtest.__init__() now copies 'ns' namespace attributes to
Regrtest attributes. Regrtest match_tests and ignore_tests
attributes have type FilterTuple (tuple), instead of a list.
* Add RunTests.copy(). Regrtest._rerun_failed_tests() now uses
RunTests.copy().
* Replace Regrtest.all_tests (list) with Regrtest.first_runtests
(RunTests).
* Make random_seed maximum 10x larger (9 digits, instead of 8).
* main() now calls _parse_args() and pass 'ns' to Regrtest
constructor. Remove kwargs argument from Regrtest.main().
* _parse_args() checks ns.huntrleaks.
* set_temp_dir() is now responsible to call expanduser().
* Regrtest.main() sets self.tests earlier.
* Add TestTuple and TestList types.
* Rename MatchTests to FilterTuple and rename MatchTestsDict
to FilterTestDict.
* TestResult.get_rerun_match_tests() return type
is now FilterTuple: return a tuple instead of a list.
RunTests.tests type becomes TestTuple.
Symbols of the C API should be prefixed by "Py_" to avoid conflict
with existing names in 3rd party C extensions on "#include <Python.h>".
test.pythoninfo now logs Py_C_RECURSION_LIMIT constant and other
_testcapi and _testinternalcapi constants.
add guard so that ``Enum('bar')`` raises a TypeError instead of
creating a new enum class called `bar`. To create the new but
empty class, use:
huh = Enum('bar', names=())
Commit 13a00078b8 (#108663) made all
Python builds compatible with the Limited API, and removed the
LIMITED_API_AVAILABLE flag. However, some tests were still checking
for that flag, so they were now being incorrectly skipped. Remove
these checks to let these tests run again.

It creates a modified copy of an object by calling the object's
__replace__() method.
It is a generalization of dataclasses.replace(), named tuple's _replace()
method and replace() methods in various classes, and supports all these
stdlib classes.
Statistics gathering is now off by default. Use the "-X pystats"
command line option or set the new PYTHONSTATS environment variable
to 1 to turn statistics gathering on at Python startup.
Statistics are no longer dumped at exit if statistics gathering was
off or statistics have been cleared.
Changes:
* Add PYTHONSTATS environment variable.
* sys._stats_dump() now returns False if statistics are not dumped
because they are all equal to zero.
* Add PyConfig._pystats member.
* Add tests on sys functions and on setting PyConfig._pystats to 1.
* Add Include/cpython/pystats.h and Include/internal/pycore_pystats.h
header files.
* Rename '_py_stats' variable to '_Py_stats'.
* Exclude Include/cpython/pystats.h from the Py_LIMITED_API.
* Move pystats.h include from object.h to Python.h.
* Add _Py_StatsOn() and _Py_StatsOff() functions. Remove
'_py_stats_struct' variable from the API: make it static in
specialize.c.
* Document API in Include/pystats.h and Include/cpython/pystats.h.
* Complete pystats documentation in Doc/using/configure.rst.
* Don't write "all zeros" stats: if _stats_off() and _stats_clear()
or _stats_dump() were called.
* _PyEval_Fini() now always call _Py_PrintSpecializationStats() which
does nothing if stats are all zeros.
Co-authored-by: Michael Droettboom <mdboom@gmail.com>
* Add get_recursion_available() and get_recursion_depth() functions
to the test.support module.
* Change infinite_recursion() default max_depth from 75 to 100.
* Fix test_tomllib recursion tests for WASI buildbots: reduce the
recursion limit and compute the maximum nested array/dict depending
on the current available recursion limit.
* test.pythoninfo logs sys.getrecursionlimit().
* Enhance test_sys tests on sys.getrecursionlimit()
and sys.setrecursionlimit().
Skip test_gdb if gdb is unable to retrieve Python frame objects: if a
frame is "<optimized out>". When Python is built with "clang -Og",
gdb can fail to retrive the 'frame' parameter of
_PyEval_EvalFrameDefault(). In this case, tests like py_bt() are
likely to fail. Without getting access to Python frames,
python-gdb.py is mostly clueless on retrieving the Python traceback.
Moreover, test_gdb is no longer skipped on macOS if Python is built
with Clang.
Fix a race condition in _ExecutorManagerThread.terminate_broken():
ignore the InvalidStateError on future.set_exception(). It can happen
if the future is cancelled before the caller.
Moreover, test_crash_big_data() now waits explicitly until the
executor completes.
Move the private _PyErr_WriteUnraisableMsg() functions to the
internal C API (pycore_pyerrors.h).
Move write_unraisable_exc() from _testcapi to _testinternalcapi.
When using --rerun option, regrtest now re-runs failed tests
in verbose mode in fresh worker processes to have more
deterministic behavior. So it can write its final report even
if a test killed a worker progress.
Add --fail-rerun option to regrtest: exit with non-zero exit code
if a test failed pass passed when re-run in verbose mode (in a
fresh process). That's now more useful since tests can pass
when re-run in a fresh worker progress, whereas they failed
when run after other tests when tests are run sequentially.
Rename --verbose2 option (-w) to --rerun. Keep --verbose2 as a
deprecated alias.
Changes:
* Fix and enhance statistics in regrtest summary. Add "(filtered)"
when --match and/or --ignore options are used.
* Add RunTests class.
* Add TestResult.get_rerun_match_tests() method
* Rewrite code to serialize/deserialize worker arguments as JSON
using a new WorkerJob class.
* Fix stats when a test is run with --forever --rerun.
* If failed test names cannot be parsed, log a warning and don't
filter tests.
* test_regrtest.test_rerun_success() now uses a marker file, since
the test is re-run in a separated process.
* Add tests on normalize_test_name() function.
* Add test_success() and test_skip() tests to test_regrtest.
- input checks for math_1(L989), math_1a(L1023), math_2(L1064,L1071), hypot(L2682), log(L2307), ldexp(L2168), ceil(L1165), floor(L1236,L1239) and dist(L2587,L2588,L2628).
- drop inaccessible "if" branch (L3518) in perm_comb_small()
- improve fsum coverage for exceptional cases (L1433,L1438,L1451,L1497), ditto fmod(L2378)
- rewrite modf to fix inaccessible case(L2229), ditto for pow(L2988)
(all line numbers are wrt the main branch at 5e6661bce9)
test_netrc, test_pep646_syntax and test_xml_etree now return results
in the test_main() function.
Changes:
* Rewrite TestResult as a dataclass with a new State class.
* Add test.support.TestStats class and Regrtest.stats_dict attribute.
* libregrtest.runtest functions now modify a TestResult instance
in-place.
* libregrtest summary lists the number of run tests and skipped
tests, and denied resources.
* Add TestResult.has_meaningful_duration() method.
* Compute TestResult duration in the upper function.
* Use time.perf_counter() instead of time.monotonic().
* Regrtest: rename 'resource_denieds' attribute to 'resource_denied'.
* Rename CHILD_ERROR to MULTIPROCESSING_ERROR.
* Use match/case syntadx to have different code depending on the
test state.

* Add 'skipped' attribute to TestResults.
* Add 'skips' attribute to DocTestRunner.
* Rename private DocTestRunner._name2ft attribute
to DocTestRunner._stats.
* Use f-string for string formatting.
* Add some tests.
* Document DocTestRunner attributes and its API for statistics.
* Document TestResults class.

The fix has two parts:
- When `-X uops` is detected, pass it on to the subprocess created to run the manufactured test.
I need this so I can run `./python -Xuops -m test test_regrtest` and see it fail without the next fix.
- Use `-R 6:3:` in `ArgsTestCase.test_huntrleaks` instead of `-R 3:3:` -- it takes longer to settle with `-X uops`.
Running test_fcntl logs two "struct.pack: ..." lines because
multiprocessing imports test_fcntl twice with
test.support.verbose=1. Move get_lockdata() inside TestFcntl test
case and only call it where it's needed, to stop logging these lines.
Argument Clinic now only includes pycore_gc.h if PyGC_Head is needed,
and only includes pycore_runtime.h if _Py_ID() is needed.
* Add 'condition' optional argument to Clinic.add_include().
* deprecate_keyword_use() includes pycore_runtime.h when using
the _PyID() function.
* Fix rendering of includes: comments start at the column 35.
* Mark PC/clinic/_wmimodule.cpp.h and
"Objects/stringlib/clinic/*.h.h" header files as generated in
.gitattributes.
Effects:
* 42 header files generated by AC no longer include the internal C
API, instead of 4 header files before. For example,
Modules/clinic/_abc.c.h no longer includes the internal C API.
* Fix _testclinic_depr.c.h: it now always includes pycore_runtime.h
to get _Py_ID().
This adds a new header that provides atomic operations on common data
types. The intention is that this will be exposed through Python.h,
although that is not the case yet. The only immediate use is in
the test file.

When overriding the `__new__` method of an enum, the underlying data type should be created directly; i.e. .
member = object.__new__(cls)
member = int.__new__(cls, value)
member = str.__new__(cls, value)
Calling `super().__new__()` finds the lookup version of `Enum.__new__`, and will now raise an exception when detected.
Python built with "configure --with-trace-refs" (tracing references)
is now ABI compatible with Python release build and debug build.
Moreover, it now also supports the Limited API.
Change Py_TRACE_REFS build:
* Remove _PyObject_EXTRA_INIT macro.
* The PyObject structure no longer has two extra members (_ob_prev
and _ob_next).
* Use a hash table (_Py_hashtable_t) to trace references (all
objects): PyInterpreterState.object_state.refchain.
* Py_TRACE_REFS build is now ABI compatible with release build and
debug build.
* Limited C API extensions can now be built with Py_TRACE_REFS:
xxlimited, xxlimited_35, _testclinic_limited.
* No longer rename PyModule_Create2() and PyModule_FromDefAndSpec2()
functions to PyModule_Create2TraceRefs() and
PyModule_FromDefAndSpec2TraceRefs().
* _Py_PrintReferenceAddresses() is now called before
finalize_interp_delete() which deletes the refchain hash table.
* test_tracemalloc find_trace() now also filters by size to ignore
the memory allocated by _PyRefchain_Trace().
Test changes for Py_TRACE_REFS:
* Add test.support.Py_TRACE_REFS constant.
* Add test_sys.test_getobjects() to test sys.getobjects() function.
* test_exceptions skips test_recursion_normalizing_with_no_memory()
and test_memory_error_in_PyErr_PrintEx() if Python is built with
Py_TRACE_REFS.
* test_repl skips test_no_memory().
* test_capi skisp test_set_nomemory().
Remove _PyErr_ChainExceptions(), _PyErr_ChainExceptions1() and
_PyErr_SetFromPyStatus() functions from the public C API.
* Move the private _PyErr_ChainExceptions() and
_PyErr_ChainExceptions1() function to the internal C API
(pycore_pyerrors.h).
* Move the private _PyErr_SetFromPyStatus() to the internal C API
(pycore_initconfig.h).
* No longer export the _PyErr_ChainExceptions() function.
* Move run_in_subinterp_with_config() from _testcapi to
_testinternalcapi.
The test was skipped in 2011 by
commit 89ba56d5fb.
Scripts in Lib/test/crashers/ do not crash on a reliable way. They
rely on undefined behaviors, like state of the stack memory, and so
may or may not crash. It is not worth it to make sure that they crash
in a continious integration, they should be run manually time to time
instead.
gh-107275 introduced a regression where a SemLock would fail being passed along nested child processes, as the `is_fork_ctx` attribute would be left missing after the first deserialization.

Deprecate passing the callback callable by keyword for the following
sqlite3.Connection APIs:
- set_authorizer(authorizer_callback)
- set_progress_handler(progress_handler, ...)
- set_trace_callback(trace_callback)
The affected parameters will become positional-only in Python 3.15.
This mis-initialization caused the executor optimization to kick in sooner than intended. It also set the lower 4 bits of the counter to `1` -- those bits are supposed to be reserved (the actual counter is in the upper 12 bits).
Change the pure Python implementation of stat.filemode() for unknown
file type: use "?", as done by the _stat.filemode().
test_stat skips TestFilemodeCStat if the _stat extension is missing.
Add test_sqlite_row_keys() to explicitly test sqlite3.Row.keys().
Cleanups:
- Reduce test noise by converting docstrings to regular comments
- Reduce boilerplate code by adding a setUp() method to RowFactoryTests
Co-authored-by: Erlend E. Aasland <erlend@python.org>
Deprecate passing name, number of arguments, and the callable as keyword
arguments, for the following sqlite3.Connection APIs:
- create_function(name, nargs, callable, ...)
- create_aggregate(name, nargs, callable)
The affected parameters will become positional-only in Python 3.15.
Refactor the CLI so we can easily invoke it and mock command-line
arguments. Adapt the CLI tests so we no longer have to launch a
separate process.
Disable the busy handler for all concurrency tests; we have full
control over the order of the SQLite C API calls, so we can safely
do this.
The sqlite3 test suite now completes ~8 times faster than before.

Argument Clinic now has a partial support of the
Limited API:
* Add --limited option to clinic.c.
* Add '_testclinic_limited' extension which is built with
the limited C API version 3.13.
* For now, hardcode in clinic.py that "_testclinic_limited.c" targets
the limited C API.
Move private functions to the internal C API (pycore_dict.h):
* _PyDictView_Intersect()
* _PyDictView_New()
* _PyDict_ContainsId()
* _PyDict_DelItemId()
* _PyDict_DelItem_KnownHash()
* _PyDict_GetItemIdWithError()
* _PyDict_GetItem_KnownHash()
* _PyDict_HasSplitTable()
* _PyDict_NewPresized()
* _PyDict_Next()
* _PyDict_Pop()
* _PyDict_SetItemId()
* _PyDict_SetItem_KnownHash()
* _PyDict_SizeOf()
No longer export most of these functions.
Move also the _PyDictViewObject structure to the internal C API.
Move dict_getitem_knownhash() function from _testcapi to the
_testinternalcapi extension. Update test_capi.test_dict for this
change.
The decorator now requires to be called with parenthesis:
@support.requires_legacy_unicode_capi()
instead of:
@support.requires_legacy_unicode_capi
The implementation now only imports _testcapi when the decorator is
called, so "import test.support" no longer imports the _testcapi
extension.
Split test_multiprocessing_fork, test_multiprocessing_forkserver and
test_multiprocessing_spawn into test packages. Each package is made
of 4 sub-tests: processes, threads, manager and misc. It allows
running more tests in parallel and so reduce the total test duration.
Currently, test_asyncio package is only splitted into sub-tests when
using command "./python -m test". With this change, it's also
splitted when passing it on the command line:
"./python -m test test_asyncio".
Remove the concept of "STDTESTS". Python is now mature enough to not
have to bother with that anymore. Removing STDTESTS simplify the
code.
The test_peg_generator and test_tools.test_freeze tests now require
the 'cpu' resource. Skip these tests unless the 'cpu' resource is
enabled (it is disabled by default).
These tests are no longer skipped if Python is built with ASAN or
MSAN sanitizer.
* In preauth tests of test_ssl, explicitly break reference cycles
invoving SingleConnectionTestServerThread to make sure that the
thread is deleted. Otherwise, the test marks the environment as
altered because the threading module sees a "dangling thread"
(SingleConnectionTestServerThread). This test leak was introduced
by the test added for the fix of issue gh-108310.
* Use support.SHORT_TIMEOUT instead of hardcoded 1.0 or 2.0 seconds
timeout.
* SingleConnectionTestServerThread.run() catchs TimeoutError
* Fix a race condition (missing synchronization) in
test_preauth_data_to_tls_client(): the server now waits until the
client connect() completed in call_after_accept().
* test_https_client_non_tls_response_ignored() calls server.join()
explicitly.
* Replace "localhost" with server.listener.getsockname()[0].
Ensure multiprocessing SemLock is valid for spawn Process before serializing it.
Creating a multiprocessing SemLock with a fork context, and then trying to pass it to a spawn-created Process, would segfault if not detected early.

* Move test_cppext to its own directory
* Rename setup_testcppext.py to setup.py
* Rename _testcppext.cpp to extension.cpp
* The source (extension.cpp) is now also copied by the test.
Instances of `ssl.SSLSocket` were vulnerable to a bypass of the TLS handshake
and included protections (like certificate verification) and treating sent
unencrypted data as if it were post-handshake TLS encrypted data.
The vulnerability is caused when a socket is connected, data is sent by the
malicious peer and stored in a buffer, and then the malicious peer closes the
socket within a small timing window before the other peers’ TLS handshake can
begin. After this sequence of events the closed socket will not immediately
attempt a TLS handshake due to not being connected but will also allow the
buffered data to be read as if a successful TLS handshake had occurred.

* Move Python scripts related to test_module to this new directory:
good_getattr.py and bad_getattrX.py scripts.
* Move Lib/test/test_module.py to Lib/test/test_module/__init__.py.
* Only skip modules and tests related to X11 on ASAN builds: run
other tests with ASAN.
* Use print(flush=True) to see output earlier when it's redirected to
a pipe.
* Update issue reference: replace bpo-46633 with gh-90791.
Set environment options to ask sanitizers to not handle SIGSEGV.
This change allows running test_enable_fd() and test_enable_file()
with sanitizers. Previously, they were skipped.
* gh-106242: Make ntpath.realpath errors consistent with abspath when there are embedded nulls
* Update 2023-08-22-00-36-57.gh-issue-106242.q24ITw.rst
mention Windows and the former incorrect ValueError.

In the stack call of: _init_read_gz()
```
_read, tarfile.py:548
read, tarfile.py:526
_init_read_gz, tarfile.py:491
```
a try;except exists that uses `self.exception`, so it needs to be set before
calling _init_read_gz().
Such C API functions as PyErr_SetString(), PyErr_Format(),
PyErr_SetFromErrnoWithFilename() and many others no longer crash or
ignore errors if it failed to format the error message or decode the
filename. Instead, they keep a corresponding error.
It is now possible to deprecate passing keyword arguments for
keyword-or-positional parameters with Argument Clinic, using the new
'/ [from X.Y]' syntax.
(To be read as "positional-only from Python version X.Y")
