0c2caeb4d8 row0sel.c, btr0pcur.c, btr0pcur.ic, btr0pcur.h: 
Add diagnostic code to track assertion failure in ut_a(cursor->old_stored == BTR_PCUR_OLD_STORED); the failure happened in OPTIMIZE TABLE, and in 4.0.24 in some other context
 2005-04-06 10:27:40 +03:00

c4ace2a471 InnoDB: Introduce the symbols REC_OFFS_NORMAL_SIZE and 
REC_OFFS_SMALL_SIZE for the initial allocation sizes of
arrays passed to rec_get_offsets().

marko@hundin.mysql.fi
fbb7d9a9df InnoDB: Write status bits to MLOG_COMP_REC_INSERT entries. 
It is not safe to infer the status bits from the B-tree page
level, because after MLOG_COMP_LIST_END_COPY_CREATED, the
level will not be initialized before the records have been inserted.
(Bug #7973)

marko@hundin.mysql.fi
7506ca1be1 InnoDB: Changed interface to rec_get_offsets(), to reduce the use of 
memory heaps.  This changeset plugs also a few memory leaks that
were introduced with the compact InnoDB table format.
 2004-12-09 15:29:55 +02:00
marko@hundin.mysql.fi
3f806c3b66 InnoDB: Make btr_search_drop_page_hash_index() work with the compact

67456bb970 btr0sea.c, buf0lru.c, buf0buf.c, ha0ha.c, hash0hash.h, ha0ha.h, buf0buf.h: 
Link adaptive hash index entries to the buffer page, so that we can remove them quickly without knowing the record structure on that page; this was requested by Marko for the compact InnoDB table format; note that the adaptive hash index memory overhead grows by 67 %, maybe we have to tune this later somehow

0614f8c718 btr0cur.c: 
Do not add + 1 to the InnoDB index cardinality estimate if the B-tree just contains one page; the fix made in March 2004 caused InnoDB systematically to overestimate the cardinality of empty or small tables by 1

a8da91f9fb btr0btr.c: 
Correct previous bk commit comment about page splits: actually, in versions < 4.0.19 space utilization is very poor if 1500 - 8000 byte rows are inserted in the order of the primary key
