The message is gramatically wrong, and factually wrong.
Change it to refer to the myisam_sort_buffer_size variable and change
"to" to "too".
myisam/sort.c:
Change error messages to be gramatically correct and to refer to the
correct variable.
mysql-test/r/repair.result:
Refer to the correct variable. Message changed.
Warnings may show up in the error log that complain about a table, yet
don't tell us which table.
Add the database and table names to the message.

Add the database and table names to the warning message.
some rollup rows (rows with NULLs for grouping attributes) if GROUP BY
list contained constant expressions.
This happened because the results of constant expressions were not put
in the temporary table used for duplicate elimination. In fact a constant
item from the GROUP BY list of a ROLLUP query can be replaced for an
Item_null_result object when a rollup row is produced .
Now the JOIN::rollup_init function wraps any constant item referenced in
the GROYP BY list of a ROLLUP query into an Item_func object of a special
class that is never detected as constant item. This ensures creation of
fields for such constant items in temporary tables and guarantees right
results when the result of the rollup operation first has to be written
into a temporary table, e.g. in the cases when duplicate elimination is
required.

sql/item_func.h:
Fixed bug #24856: the result set of a ROLLUP query with DISTINCT could lack
some rollup rows (rows with NULLs for grouping attributes) if GROUP BY
list contained constant expressions.
Itroduced class Item_func_rollup_const derived from Item_func. The object of
this class are never detected as constant items.
We use them for wrapping constant items from the GROUP BY list of any ROLLUP
query. This wrapping allows us to ensure writing constant items into temporary
tables whenever the result of the ROLLUP operation has to be written into a
temporary table, e.g. when ROLLUP is used together with DISTINCT in the SELECT
list.

INSERT...ON DUPLICATE KEY UPDATE may cause error 1032:
"Can't find record in ..." if we are inserting into
InnoDB table unique index of partial key with
underlying UTF-8 string field.
This error occurs because INSERT...ON DUPLICATE uses a wrong
procedure to copy string fields of multi-byte character sets
for index search.

Fixed bug #13191.
Field_string::get_key_image() virtual function was overloaded
to implement copying of variable length character (UTF-8) fields.
Field::get_key_image() function prototype has been changed to
return byte size of copied data.

This bug occurs when error message length exceeds allowed limit: my_error()
function outputs "%s" sequences instead of long string arguments.
Formats like %-.64s are very common in errmsg.txt files, however my_error()
function simply ignores precision of those formats.
mysys/my_error.c:

IGNORE/USE/FORCE INDEX hints were honored when choosing FULLTEXT
index.
With this fix these hints are ignored. For regular indexes we may
perform table scan instead of index lookup when IGNORE INDEX was
specified. We cannot do this for FULLTEXT in NLQ mode.

Added a function to check compatibility of row expressions. Made sure that this
function to be called for Item_func_in objects by fix_length_and_dec().

MERGE engine may return incorrect values when several representations
of equal keys are present in the index. For example "groß" and "gross"
or "gross" and "gross " (trailing space), which are considered equal,
but have different lengths.
The problem was that key length was not recalculated after key lookup.
Only MERGE engine is affected.
myisam/mi_rkey.c:
info->lastkey gets rewritten by mi_search. Later we recalculate found lastkey
length. This is done to make sure that mi_rnext_same gets true, found (not
searched) lastkey length. Searched and found key lengths may be different,
for example in case searched key is "groß" and found is "gross" or in case
a key has trailing spaces.
Unfortunately we recalculate found lastkey length only for first
underlying table. To recalculate found key length for non-first underlying
table we need to know how much key segments were used to create this key.
When mi_rkey is called for first underlying table of a merge table, store
offset to last used key segment.
Restore last_used_keyseg variable when mi_rkey is called for non-first
underlying table.
myisam/myisamdef.h:
Added last_used_keyseg variable to MI_INFO. It is used by merge engine to calculate
key length.
myisammrg/myrg_rkey.c:
Pass last used key segment returned by first table key read to other
table key reads.
