Re: LMDB: issue with mdb_cursor_del

Maybe mdb_page_dirty could be allowed to simply accept -1 as a return value from insert() and that could fix it? Since the page is already listed in the txn's dirty list, it shouldn't really matter. Or am I misunderstanding the consequences of this?

Sure this will not create problems when working without MDB_WRITEMAP. But in MDB_WRITEMAP mode duplicates in the dirty-list seems may leads some side affects. Therefore in MDBX I had planned to completely rewrite freelist_save().

PS. Howard, I'm doing the slides right now and will not go to bed until it's done.
