8cc5fe116f Bug#4692 - DISABLE/ENABLE KEYS waste a space 
Disabling and enabling indexes on a non-empty table grows the
index file.

Disabling indexes just sets a flag per non-unique index and does not
free the index blocks of the affected indexes. Re-enabling indexes
creates new indexes with new blocks. The old blocks remain unused
in the index file.

Fixed by dropping and re-creating all indexes if non-empty disabled
indexes exist when enabling indexes. Dropping all indexes resets
the internal end-of-file marker to the end of the index file header.
It also clears the root block pointers of every index and clears the
deleted blocks chains. This way all blocks are declared as free.

fe03f6bbe0 Bug #27531: 5.1 part of the fix 
- Renamed "Using join cache" to "Using join buffer".
- "Using join buffer" is now printed on the last
  table that "reads" from the join buffer cache.

306371a850 bug #27531: 5.1 part of the fix: 
- added join cache indication in EXPLAIN (Extra column).
 - prefer filesort over full scan over 
   index for ORDER BY (because it's faster).
 - when switching from REF to RANGE because
   RANGE uses longer key turn off sort on
   the head table only as the resulting 
   RANGE access is a candidate for join cache
   and we don't want to disable it by sorting
   on the first table only.

c33486ff1b Bug#26231 - select count(*) on myisam table returns wrong value 
when index is used

When the table contained TEXT columns with empty contents
('', zero length, but not NULL) _and_ strings starting with
control characters like tabulator or newline, the empty values
were not found in a "records in range" estimate. Hence count(*)
missed these records.

The reason was a different set of search flags used for key
insert and key range estimation.

I decided to fix the set of flags used in range estimation.
Otherwise millions of databases around the world would require
a repair after an upgrade.

The consequence is that the manual must be fixed, which claims
that TEXT columns are compared with "end space padding". This
is true for CHAR/VARCHAR but wrong for TEXT. See also bug 21335.

a2d4a042d0 Fixed bug #25971: indexes on text columns were ignored when ref accesses 
were evaluated.
According to the new rules for string comparison partial indexes on text
columns can be used in the same cases when partial indexes on varchar
columns can be used.

An update that used a join of a table to itself and modified the
table on one side of the join reported the table as crashed or
updated wrong rows.
