HOUR(), MINUTE(), ... returned spurious results when used on a DATE-cast.
This happened because DATE-cast object did not overload get_time() method
in superclass Item. The default method was inappropriate here and
misinterpreted the data.
Patch adds missing method; get_time() on DATE-casts now returns SQL-NULL
on NULL input, 0 otherwise. This coincides with the way DATE-columns
behave.

Problem: the new_item() method of Item_uint used an incorrect
constructor. "new Item_uint(name, max_length)" calls
Item_uint::Item_uint(const char *str_arg, uint length) which assumes the
first argument to be the string representation of the value, not the
item's name. This could result in either a server crash or incorrect
results depending on usage scenarios.
Fixed by using the correct constructor in new_item():
Item_uint::Item_uint(const char *str_arg, longlong i, uint length).

The problem was that the optimizer used the join buffer in cases when
the result set is ordered by filesort. This resulted in the ORDER BY
clause being ignored, and the records being returned in the order
determined by the order of matching records in the last table in join.
Fixed by relaxing the condition in make_join_readinfo() to take
filesort-ordered result sets into account, not only index-ordered ones.

!join->skip_sort_order' is true.
With certain data sets (when compressed record length gets bigger than
uncompressed) myisamchk --unpack may corrupt data file.
Fixed that record length was wrongly restored from compressed table.
myisam/mi_check.c:
With compressed tables compressed record length may be bigger than
pack_reclength, thus we may allocate insufficient memory for record
buffer.
Let single function allocate record buffer, performing needed record
length calculations.
Still, it is not doable with parallel repair, as it allocates needed
record buffers at once. For parellel repair added better record length
calculation.
myisam/mi_open.c:
When calculating record buffer size, take into account that compressed
record length may be bigger than uncompressed.
myisam/mi_packrec.c:
With certain data set share->max_pack_length (compressed record length)
may be bigger than share->base.pack_reclength (packed record length).
set_if_bigger(pack_reclength, max_pack_length) in this case causes
myisamchk --unpack to write extra garbage, whereas pack_reclength
remains the same in new index file. As a result we get unreadable
table.

ChangeSet@1.2536.50.1 2007-08-02 12:45:56-07:00 igor@mysql.com
Fixed bug#28404.
This patch adds cost estimation for the queries with ORDER BY / GROUP BY
and LIMIT.
If there was a ref/range access to the table whose rows were required
to be ordered in the result set the optimizer always employed this access
though a scan by a different index that was compatible with the required
order could be cheaper to produce the first L rows of the result set.
Now for such queries the optimizer makes a choice between the cheapest
ref/range accesses not compatible with the given order and index scans
compatible with it.

bug #28404.

Revision r1820:
Use the clustered index and not the one selected by the optimizer in the plan,
when building a previous version of the row. This bug is triggered when
running queries via InnoDB's internal SQL parser; when InnoDB's optimizer
selects a secondary index for the plan.
Revision r1828:
Fix two bugs:
Bug# 30907: We don't rely on *first_value to be 0 when checking whether
get_auto_increment() has been invoked for the first time in a multi-row
INSERT. We instead use trx_t::n_autoinc_rows. Initialize trx::n_autoinc_rows
inside ha_innobase::start_stmt() too.
Bug# 30888: While adding code for the low level read of the AUTOINC value
from the index, the case for MEDIUM ints which are 3 bytes was missed
triggering an assertion.
Revision r1779:
Fix a bug that handles the case where the host specific byte order matches
the InnoDB storage byte order, which is big-endian.

Revision r1873:
snprintf() should always return non-negative result. According to
Microsoft documentation about _vscprintf():
If format is a null pointer, the invalid parameter handler is invoked,
as described in Parameter Validation. If execution is allowed to
continue, the functions return -1 and set errno to EINVAL.
The UNIX variant of snprintf() segfaults if format is a NULL pointer
(similar to strlen(NULL) for example), so it is better to conform to
this behavior and crash our custom Windows version instead of
returning -1. Noone would expect -1 to be returned from snprintf().
Cosmetic: Add a space after typecast.
Approved by: Marko
Revision r1862:
Add ut_snprintf() function. On Windows this needs to be implemented
using auxiliary functions because there is no snprintf-variant on
Windows that behaves exactly as specified in the standard:
* Always return the number of characters that would have been printed
if the size were unlimited (not including the final `\0').
* Always '\0'-terminate the result
* Do not touch the buffer if size=0, only return the number of characters
that would have been printed. Can be used to estimate the size needed
and to allocate it dynamically.
See http://www.freebsd.org/cgi/query-pr.cgi?pr=87260 for the reason why
2 ap variables are used.

In BUG#30244 added FOUND_ROWS() as an unsafe function, but that
works only in mixed mode under 5.1. There is a workaround that
can be used in statement-based mode either under 5.0 or 5.1
where the result of FOUND_ROWS() is stored into a user vari-
able and used that way instead. This will replicate correctly
even under statement-based replication, since it will write
a User_var entry to the binary log. For some other cases, the
value has to be passed explicitly.
This patch adds tests to demonstrate that the workarounds docu-
mented for statement-based replication works as advertised, and
does more extensive tests for cases that does not work under sta-
tement-based replication actually work under mixed mode by switch-
ing to row-based replication.

RENAME TABLE against a table with DATA/INDEX DIRECTORY overwrites
the file to which the symlink points.
This is security issue, because it is possible to create a table with
some name in some non-system database and set DATA/INDEX DIRECTORY
to mysql system database. Renaming this table to one of mysql system
tables (e.g. user, host) would overwrite the system table.

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.

partitioned table
Trying INSERT DELAYED on a partitioned table, that has not been
used right before, crashes the server. When a table is used for
select or update, it is kept open for some time. This period I
mean with "right before".
Information about partitioning of a table is stored in form of
a string in the .frm file. Parsing of this string requires a
correctly set up lexical analyzer (lex). The partitioning code
uses a new temporary instance of a lex. But it does still refer
to the previously active lex. The delayd insert thread does not
initialize its lex though...
Added initialization for thd->lex before open table in the delayed
thread and at all other places where it is necessary to call
lex_start() if all tables would be partitioned and need to parse
the .frm file.
