Sorry, something went wrong.
…nGH-158475) python-gdb.py is now able to format an invalid Unicode string: render invalid characters as "\Uhhhhhhhh" instead of raising an exception. The PyUnicodeWriter API fills a UCS-4 buffer with 0xff byte pattern to detect usage of uninitialized characters. It produces invalid characters '\Uffffffff'. PyBytesObjectPtr now iterates on bytes (list of integers), instead of creating a temporary Unicode string. Add more bytes tests in test_gdb pretty printer. Remove the unused 'ch2' variable. (cherry picked from commit 7eada7c) Co-authored-by: Victor Stinner <vstinner@python.org>
