Add a new _testcapi._read_null() function to crash Python in a
reliable way on s390x.
On s390x, ctypes.string_at(0) returns an empty string rather than
crashing.
The current test_child_terminated_in_stopped_state() function test
creates a child process which calls ptrace(PTRACE_TRACEME, 0, 0) and
then crash (SIGSEGV). The problem is that calling os.waitpid() in the
parent process is not enough to close the process: the child process
remains alive and so the unit test leaks a child process in a
strange state. Closing the child process requires non-trivial code,
maybe platform specific.
Remove the functional test and replaces it with an unit test which
mocks os.waitpid() using a new _testcapi.W_STOPCODE() function to
test the WIFSTOPPED() path.
(cherry picked from commit 7b7c6dcfff)
* Add Windows support to test.support.SuppressCrashReport: call
SetErrorMode() and CrtSetReportMode().
* _testcapi: add CrtSetReportMode() and CrtSetReportFile() functions
and CRT_xxx and CRTDBG_xxx constants needed by SuppressCrashReport.
* bpo-30283: regrtest: add --testdir option
* bpo-30283: Backport _testcapi.raise_signal()
Function used by test_regrtest to simulate an interrupted unit test.
* bpo-30283: Backport test_regrtest from master
Fix a crash when a generator is created in a C thread that is destroyed while
the generator is still used. The issue was that a generator contains a frame,
and the frame kept a reference to the Python state of the destroyed C thread.
The crash occurs when a trace function is setup.
- rename to _test_structmembersType to avoid the class being automatically
called by test_capi
- allow space for trailing NUL in inplace_member field of all_structmembers
- use T_STRING_INPLACE instead of T_INPLACE_STRING as keyword argument
to _test_structmembersType initializer
- don't attempt to initialize inplace_member field if T_STRING_INPLACE
argument wasn't supplied.
Most uses of PyCode_New found by http://www.google.com/codesearch?q=PyCode_New
are trying to build an empty code object, usually to put it in a dummy frame
object. This patch adds a PyCode_NewEmpty wrapper which lets the user specify
just the filename, function name, and first line number, instead of also
requiring lots of code internals.
sizeof(Py_UNICODE) == 2, PyUnicode_FromWideChar now converts
each character outside the BMP to the appropriate surrogate pair.
Thanks Victor Stinner for the patch.
