Factor-out subroutine to run tfunc in subprocess interpreter spawned with `-X xopt=xval`. This helps clarity and later in addition to `-X gpython.runtime` we will also need it to verify `-X gpython.strings`. /proposed-for-review-on !25

Pytest 7.4 changed format of output tracebacks. Similarly to IPython adding test support for later versions would add maintenance cost on pygolang side, but testing this is actually not needed, since we activate Pytest-related patch only on py2 and for py2 the latest pytest version is pytest 4.6.11. -> So simply skip this test if we see we have Pytest ≥ 7.4. Skip it only on py3 just in case. For the reference here is how diff in between running golang_test_defer_excchain.py on Pytest 7.3 and Pytest 7.4 looks: diff --git a/a b/b index 45680b99..47c29cea 100644 --- a/a +++ b/b @@ -1,5 +1,5 @@ ============================= test session starts ============================== -platform linux -- Python 3.12.2+, pytest-7.3.2, pluggy-1.4.0 +platform linux -- Python 3.12.2+, pytest-7.4.0, pluggy-1.4.0 rootdir: /home/kirr/src/tools/go/pygolang-master collected 1 item @@ -7,22 +7,16 @@ golang/testprog/golang_test_defer_excchain.py F [100%] =================================== FAILURES =================================== _____________________________________ main _____________________________________ -golang/__init__.py:106: in _ - return f(*argv, **kw) golang/testprog/golang_test_defer_excchain.py:42: in main raise RuntimeError("err") E RuntimeError: err During handling of the above exception, another exception occurred: -golang/__init__.py:183: in __exit__ - d() golang/testprog/golang_test_defer_excchain.py:31: in d1 raise RuntimeError("d1: aaa") E RuntimeError: d1: aaa During handling of the above exception, another exception occurred: -golang/__init__.py:183: in __exit__ - d() golang/testprog/golang_test_defer_excchain.py:33: in d2 1/0 E ZeroDivisionError: division by zero /reviewed-by @jerome /reviewed-on !23

Unfortunately the best Cython release ever[1] breaks build for Pygolang[2], and people on the net also report that there are other problems - both build failures and popped up performance problems due to changed semantic[3,4,...]. Fix it all on Pygolang side by, for now, not delving into being Cython 3 beta-testers and relying on field-proven Cython 2. /reported-by @levin.zimmermann [1] https://groups.google.com/g/cython-users/c/o41CrcRkVvo [2] wendelin.core!16 (comment 188623) [3] https://news.ycombinator.com/item?id=36778617 [4] https://github.com/cython/cython/issues/5540

When underlying pygfobj is FileObjectThread its .readinto() leads to deadlock because it is no cooperative(*). This manifests as test_pyx_os_pipe_cpp hang when run by gpython on windows. -> Workaround this by reading first into intermediate buffer and then copying data to buffer that user provided. After this the deadlock is gone but test_pyx_os_pipe_cpp starts to fail and crash randomly. That's because similarly to channels we need to care and not access a buffer if it is located on stack and owning greenlet is inactive. Because when a greenlet is inactive, its stack is reused by another active greenlet and writing/reading to on-stack memory accesses that second greenlet stack, corrupting it on write. -> do the same what we do in chan operations: use intermediate on-heap buffer to protect original user's buffer to be accesses because it might be located on stack. That's what actually happens in test_pyx_os_pipe_cpp where two goroutines read and write to each other via pipe and using on-stack located buffers. And becuase on windows pipes, like regular files, are wrapped with FileObjectThread, when reading greenlet becomes suspended waiting for read reasul, it will be another greenlet to run on its stack, write to another end of a pipe, wakeup IO thread, which will write the data to requested buffer on G1 stack and oops - it was G2 there.

On windows upon terminating signal reception exict code of the process is always 3 instead of -signo. And so test_signal_all was failing as def test_signal_all(): retcode, out, _ = _pyrun([dir_testprog + "/signal_test_all.py"], stdout=PIPE) assert b"ok (notify)" in out assert b"ok (ignore)" in out assert b"terminating ..." in out > assert retcode == -syscall.SIGTERM.signo E assert 3 == -15 E + where 15 = os.Signal(15).signo E + where os.Signal(15) = syscall.SIGTERM

Because on Windows os.kill unconditionally terminates target process, even if own self, instead of sending it any kind of signal.

We use SIGUSR1/SIGUSR2 mainly in this test, but those signals are not available on Windows: @func def test_signal(): # Notify/Stop with wrong chan dtype -> panic _ = panics("pychan: channel type mismatch") > with _: signal.Notify(chan(2), syscall.SIGUSR1) E AttributeError: module 'golang.syscall' has no attribute 'SIGUSR1' -> Use SIGTERM/SIGINT if SIGUSR1/SIGUSR2 are not available. Don't want to use SIGTERM/SIGINT unconditionally because those signals are better to leave for the job control so that e.g. nxdtest can properly kill spawned pygolang tests.

On Windows in text mode files are opened with encoding=locale.getdefaultlocale() which is CP125X instead of UTF-8 even if $PYTHONIOENCODING=UTF-8. This way e.g. test_strings_print fail as: E Failed: not equal: E Expected: E print(qq(b)): "привет О±ОІОі b" E print(qq(u)): "привет О±ОІОі u" E Got: E print(qq(b)): "привет αβγ b" E print(qq(u)): "привет αβγ u" where "Expected" was read from golang/testprog/golang_test_str.txt and decoded wrongly. -> Fix it by always opening files for reading in binary mode and utf8-decoding manually, if needed, everywhere.

golang: tests: Spawn subprocess python with $PYTHONIOENCODING set to encoding of stdin/stdout/stderr We need to do it because on Windows `python x.py | ...` runs with stdio encoding set to cp125X even if just `python x.py` runs with stdio encoding=UTF-8. (1.wenv) Z:\home\kirr\src\tools\go\pygo-win\pygolang\golang\testprog>python golang_test_str.py print(qq(b)): "привет b" print(qq(u)): "привет u" (1.wenv) Z:\home\kirr\src\tools\go\pygo-win\pygolang\golang\testprog>python golang_test_str.py |more print(qq(b)): "яЁштхЄ b" print(qq(u)): "яЁштхЄ u" (1.wenv) Z:\home\kirr\src\tools\go\pygo-win\pygolang\golang\testprog>python golang_test_str.py >aaa.txt (1.wenv) Z:\home\kirr\src\tools\go\pygo-win\pygolang\golang\testprog>type aaa.txt print(qq(b)): "яЁштхЄ b" print(qq(u)): "яЁштхЄ u" Which leads to the following test_strings_print failure: E Failed: not equal: E Expected: E print(qq(b)): "привет b" E print(qq(u)): "привет u" E Got: E print(qq(b)): "������ b" E print(qq(u)): "������ u" We also change golang_test_str.py to print not only russian and english letters, but also greek ones. This is to make sure that stdout IO encoding would not go cp125X unnoticed because then printing will fail with UnicodeEncodeError. Note: in the above example both got and expected are wrong. Via $PYTHONIOENCODING we only fix "got" and we will fix "expected" in the followup patch. After current patch test_strings_print result is E Failed: not equal: E Expected: E print(qq(b)): "привет О±ОІОі b" E print(qq(u)): "привет О±ОІОі u" E Got: E print(qq(b)): "привет αβγ b" E print(qq(u)): "привет αβγ u"

Libpyxruntime by definition contains python-specific code and we already compile it with include path having python includes in it.

On MSVC there is no sigaction and we have to use signal. Fortunately our sigaction usage in os/signal can be practically emulated because we do not use all features of sigaction and because on MSVC there is SIG_GET signal extension to query current signal handler without resetting it. Because the emulation is limited we keep it in os/signal.cpp instead of adjusting syscall::Sigaction .

On MSVC we will need to use signal(2), because there is no sigaction, and sigaction will be partly emulated through that. Move signal setting code into common place as a preparatory step.

- there is no strerror_r, but strerror_s instead - fcntl is not supported - we need to explicitly tell open to open files in binary mode - pipes are created via _pipe and explicitly in binary mode - there is no sigaction.

This way e.g. O_CLOEXEC can be passed in at pipe creation time removing potential race in between pipe+fcntl vs exec in the middle. It will also help in windows porting in follow-up patches becuase there is no fcntl on Windows, but pipe with O_CLOEXEC semantic can be created directly with flags=_O_NOINHERIT.
