As for splitting a leaf, root is just the leaf, and tree mod log does not apply on leaf, so in this case, we don''t do log_removal. As for splitting a node, the old root is kept as a normal node and we have nicely put records in tree mod log for moving keys and items, so in this case we don''t do that either. As above, insert_new_root can get rid of log_removal. Signed-off-by: Liu Bo <bo.li.liu@oracle.com> -...

Hi, I''m using an ActiveRecord::Observer to log users changing data in my application. However, I''ve noted that adding an item to a has_many relationship gets logged, but removing the item does not. That is: @product.users << user is logged, but: @product.users.delete(user) is not. I''ve dug into ActiveRecord and found that the underlying issue is that the

I wanted it to be "smart". 2) Didn''t want to "alias_method" any Rails code. I thoug...
