Overview
This commit adds the
DB.NoTruncate
flag to optionally revertmmap()
calls to how they were implemented before the ext3/ext4 fix. WhenNoTruncate
is true, remapping the data file will not force the file system to resize it immediately. This works for non-ext3/4 file systems.The default value of
NoTruncate
isfalse
so it is still safe for ext3/ext4 file systems by default.See also: #284
