even if myisam-recover is OFF
The problem was that a corrupted MyISAM table was auto repaired
even if the myisam_recover_options server variable (or the
myisam_recover option) was set to OFF.
The reason was that the auto_repair() function, which is supposed
to say if auto repair is to be used, did not use the server variable
setting correctly. This bug was a regression introduced by WL#4738.
This patch fixes the problem by making sure auto_repair() returns
FALSE if myisam_recover_options is set to OFF.
Test case added to myisam.test.

insert...select
Queries following bulk insert into an empty MyISAM table
may break it. This was pure MyISAM problem.
When bulk insert into an empty table is complete, MyISAM
may want to enable indexes via repair by sort. If repair
by sort fails (e.g. insufficient buffer), MyISAM failover
to repair with key cache, requesting repair of data file.
Repair of data file performs data file substitution. This
means that current table instance will point to new data
file. Other cached table instances are still pointing to
an old, deleted data file.
This is fixed by not requesting repair of data file
during enable indexes.
Explicit REPAIR is not affected, since it flushes all
table instances.

Bulk REPLACE or bulk INSERT ... ON DUPLICATE KEY UPDATE may

The problem is limited to bulk REPLACE and INSERT ... ON
DUPLICATE KEY UPDATE, because only these operations may

cache to seek to a correct position.

table and view...
Invalid memory reads after a query referencing MyISAM table
multiple times with write lock. Invalid memory reads may
lead to server crash, valgrind warnings, incorrect values
in INFORMATION_SCHEMA.TABLES.{TABLE_ROWS, DATA_LENGTH,
INDEX_LENGTH, ...}.
This may happen when one of the table instances gets closed
after a query, e.g. out of slots in open tables cache. UNION,
MERGE and VIEW are irrelevant.
The problem was that MyISAM didn't restore state info
pointer to default value.
myisam/mi_locking.c:
When a query is referencing MyISAM table multiple times
with a write lock, all table instances share the same
state info, pointing to MI_INFO::save_state of
"primary" table instance.
When lock is released, state pointer was restored only
for the primary table instance. Secondary table instances
are still pointing to save_state of primary table
instance.
Primary table instance may get closed, leaving secondary
table instances state pointer pointing to freed memory.
That's mostly ok, since next lock will update state info
pointer to correct value. But there're some cases, when
this secondary table instance state info is accessed
without a lock, e.g. INFORMATION_SCHEMA, MERGE (in 5.1
and up), MyISAM itself for DBUG purposes.
Restore default value of state pointer unconditionally,
for both primary and secondary table instances.

message:
Bug#25858 Some DROP TABLE under LOCK TABLES can cause deadlocks
When a client (connection) holds a lock on a table and attempts to
drop (obtain a exclusive lock) on a second table that is already
held by a second client and the second client then attempts to
drop the table that is held by the first client, leads to a
circular wait deadlock. This scenario is very similar to trying to
drop (or rename) a table while holding read locks and are
correctly forbidden.
The solution is to allow a drop table operation to continue only
if the table being dropped is write (exclusively) locked, or if
the table is temporary, or if the client is not holding any
locks. Using this scheme prevents the creation of a circular
chain in which each client is waiting for one table that the
next client in the chain is holding.
This is incompatible change, as can be seen by number of tests
cases that needed to be fixed, but is consistent with respect to
behavior of the different scenarios in which the circular wait
might happen.

low myisam_sort_buffer_size
Repair by sort (default) or parallel repair of a MyISAM table
(doesn't matter partitioned or not) as well as bulk inserts
and enable indexes some times didn't failover to repair with
key cache.
The problem was that after unsuccessful attempt, data file was
closed. Whereas repair with key cache requires open data file.
Fixed by reopening data file.
Also fixed a valgrind warning, which may appear during repair
by sort or parallel repair with certain myisam_sort_buffer_size
number of rows and length of an index entry (very dependent).

storage/myisam/mi_check.c:
Reopen data file, when repair by sort or parallel repair
fails.
When repair by sort is requested to rebuild data file, data file
gets rebuilt while fixing first index. When rebuild is completed,
info->dfile is pointing to temporary data file, original data file
is closed.
It may happen that repair has successfully fixed first index and
rebuilt data file, but failed to fix second index. E.g.
myisam_sort_buffer_size was big enough to fix first shorter index,
but not enough to fix subsequent longer index.
In this case we end up with info->dfile pointing to temporary file,
which is removed and info->dfile is set to -1.
Though repair by sort failed, the upper layer may still want to
try repair with key cache. But it needs info->dfile pointing to
valid data file.
storage/myisam/sort.c:
When performing a copy of IO_CACHE structure, current_pos and
current_end must be updated separatly to point to memory we're
copying to (not to memory we're copying from).
As t_file2 is always WRITE cache, proper members are write_pos
and write_end accordingly.
checksum)"
The problem was that checksum of GEOMETRY type used memory addresses
in the computation, making it un-repeatable thus useless.

sql/sql_table.cc:
Type GEOMETRY is implemented on top of type BLOB, so, just like for BLOB,
its 'field' contains pointers which it does not make sense to include in
the checksum; it rather has to be converted to a string and then we can
compute the checksum.

Server handles truncation for assignment of too-long values
into CHAR/VARCHAR/TEXT columns in a different ways when the
truncated characters are spaces:
1. CHAR(N) columns silently ignore end-space truncation;
2. TEXT columns post a truncation warning/error in the
non-strict/strict mode.
3. VARCHAR columns always post a truncation note in
any mode.
Space truncation processing has been synchronised over
CHAR/VARCHAR/TEXT columns: current behavior of VARCHAR
columns has been propagated as standard.
Binary-encoded string/BLOB columns are not affected.

2. to BLOBs: a check for space truncation has been added,
a warning in the non-strict mode and an error message in
the strict mode have been replaced with a truncation note.
Similar parts of Field_string::store, Field_blob::store and
Field_varstring::store have been moved to the
Field_longstr::report_if_important_data method.

CHECK TABLE (non-QUICK) and any form of repair table did wrongly rate
records as corrupted under the following conditions:
1. The table has dynamic row format and

3. it has records with > 127 bytes significant length in that column

Fixed some small coding style violations near the changes.
at page 1024 with ucs2_bin
Inserting strings with a common prefix into a table with
characterset UCS2 corrupted the table.
An efficient search method was used, which compares end space
with ASCII blank. This doesn't work for character sets like UCS2,
which do not encode blank like ASCII does.
Use the less efficient search method _mi_seq_search()
for charsets with mbminlen > 1.

Bug#32705 - myisam corruption: Key in wrong position
at page 1024 with ucs2_bin
Use _mi_seq_search() for charsets with mbminlen > 1.
