| | | | | | | | | | | | | | | | Fix incorrect handling of exceptions when interpreting dialect objects in the csv module. Not clearing exceptions between calls to PyObject_GetAttrString() causes assertion failures in pydebug mode (or with assertions enabled). Add a minimal test that would've caught this (passing None as dialect, or any object that isn't a csv.Dialect subclass, which the csv module allows and caters to, even though it is not documented.) In pydebug mode, the test triggers the assertion failure in the old code. Contributed-By: T. Wouters [Google] (cherry picked from commit 0093876328afa330224c9d887c18dee0b3117852) Co-authored-by: T.

* bpo-44434: Don't call PyThread_exit_thread() explicitly (GH-26758) (GH-26825)Victor Stinner2021-06-211-1/+4
| | | | | | | | | | | | | | | | | | | | | | | | _thread.start_new_thread() no longer calls PyThread_exit_thread() explicitly at the thread exit, the call was redundant. On Linux with the glibc, pthread_cancel() loads dynamically the libgcc_s.so.1 library. dlopen() can fail if there is no more available file descriptor to open the file. In this case, the process aborts with the error message: "libgcc_s.so.1 must be installed for pthread_cancel to work" pthread_cancel() unwinds back to the thread's wrapping function that calls the thread entry point. The unwind function is dynamically loaded from the libgcc_s library since it is tightly coupled to the C compiler (GCC). The unwinder depends on DWARF, the compiler generates DWARF, so the unwinder belongs to the compiler. Thanks Florian Weimer and Carlos O'Donell for their help on investigating this issue.
