Hi, Howard.

Why mdb_cursor_put() doesn't copy the rest of page in case MDB_RESERVE?

For MDB_RESERVE the caller is going to supply their own data later, so nothing on the page is valid data.

Yes, it's obvious. But I asked not about of a user data. In other words - why we should copy or not copy an end of page in dependence from MDB_RESERVE?

It is here (current mdb.master, mdb.c line 7479) = http://www.openldap.org/devel/gitweb.cgi?p=openldap.git;a=blob;f=libraries/l...
