Hi, Jiah He!


1. v57-0001-refactor-for-v57.no-cfbot
Thanks, the patch make the code clearer.
I added small correction in function check_partition_bounds_for_split_range.
Before the patch, the old code contained the condition:
---------------------------------
if (!defaultPart)
{
	if (cmpval != 0)
...
}
else
{
	if (cmpval < 0)
...
}
---------------------------------
The patch changed this to:
---------------------------------
if (!defaultPart && cmpval != 0)
...
else if (cmpval < 0)
...
---------------------------------
This change is not equivalent to the old code, so it replaced with:
---------------------------------
if (!defaultPart)
{
	if (cmpval != 0)
....
}
else if (cmpval < 0)
...
---------------------------------

Applied (I agree, readability improved).
