# There is no use in testing the maximum expanded filename using "#" or
# some other character that is expanded by MySQL to "@0023" because
# Windows imposes a maximum absolute path length of 260 bytes. So the
# results will depend upon what local directory this test is run in.
# See https://msdn.microsoft.com/en-us/library/aa365247.aspx
# "Maximum Path Length Limitation
# In the Windows API, the maximum length for a path is MAX_PATH, which is
# defined as 260 characters. A local path is structured in the following
# order: drive letter, colon, backslash, name components separated by
# backslashes, and a terminating null character. For example, the maximum
# path on drive D is "D:\some 256-character path string<NUL>" where
# "<NUL>" represents the invisible terminating null character for the
# current system codepage. (The characters < > are used here for visual
# clarity and cannot be part of a valid path string.)"

# This will test the limit of a filename in MySQL at 512 bytes.
# We control that by making it a relative path starting with "./".
# The embedded server uses an absolute path as the datadir
# which has a non-deterministic length.
