[3.6] bpo-32890, os: Use errno instead of GetLastError() in execve() and truncate() (GH-5784)#9985
Merged
Conversation
…uncate() (pythonGH-5784) path_error() uses GetLastError() on Windows, but some os functions are implemented via CRT APIs which report errors via errno. This may result in raising OSError with invalid error code (such as zero). Introduce posix_path_error() function and use it where appropriate.
