示例1: add_file
# 需要导入模块: from fbuild.path import Path [as 别名]
# 或者: from fbuild.path.Path import digest [as 别名]

of the file is different from what was in the table."""

# Now, create a path object and find it's mtime.

file_mtime = file_path.getmtime()
if old_mtime is not None:

# hash since it still could have changed even with the same mtime.
# If True, then assume the file has not been modified.
if file_mtime == old_mtime and time.time() - file_mtime > 1.0:
