Bug#30919
"Rows not deleted from innodb partitioned tables if
--innodb_autoinc_lock_mode=0"
Due to a previous bugfix which initializes a previously uninitialized
variable, ha_partition::get_auto_increment() may fail to operate
correctly when the storage engine reports that it is only reserving
one value and one or more partitions have a different 'next-value'.
Currently, only affects Innodb's new-style auto-increment code which
reserves larger blocks of values and has less inter-thread contention.

Bug30919
Only set *first_value if it is less than autoinc value. This allows
a higher value to be hinted when operating as a partitioned table.

"Database crash due to ha_innodb.cc:3896: ulint convert_search_mode_to_innobase":
When unknown find_flag is encountered in convert_search_mode_to_innobase()
do not call assert(0); instead queue a MySQL error using my_error() and
return the error code PAGE_CUR_UNSUPP. Change the functions that call
convert_search_mode_to_innobase() to handle that error code by "canceling"
execution and returning appropriate error code further upstream.

Fix another compiler warning on Windows in InnoDB.
ha_innodb.cc:
Fix compiler warning: ::get_auto_increment takes a ulonglong
for nb_desired_values, but InnoDB's trx struct stores it as
a ulint (unsigned long). Probably harmless, as a single
statement won't be asking for more than 2^32 rows.

retry of autoinc read semantics. We always reread the table's autoinc counter
after attempting to initialize it i.e., we want to guarantee that a read of
autoinc valus that is returned to the caller is always covered by the
AUTOINC locking mechanism.
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.
trx->n_mysql_tables_in_use only after row_lock_table_for_mysql()
returns DB_SUCCESS. A timeout on LOCK TABLES would lead to an
inconsistent state, which would cause trx_free() to print a warning.
This was later reported as Bug #31444.
pending and/or granted on a table. We peek at this value to determine whether
a transaction doing a simple INSERT in innodb_autoinc_lock_mode = 1, needs to
acquire the AUTOINC lock or not. This change is related to Bug# 16979.
AUTOINC locking. There are three modes, 0 for backward compatibility, 1 for the
new style locking (default, safe for statement-based replication) and
2 for no AUTOINC locking (unsafe for statement-based replication).

Bug #29644: alter table hangs if records locked in share mode
by long running transaction
On Windows opened files can't be deleted. There was a special
upgraded lock mode (TL_WRITE instead of TL_WRITE_ALLOW_READ)
in ALTER TABLE to make sure nobody has the table opened
when deleting the old table in ALTER TABLE. This special mode
was causing ALTER TABLE to hang waiting on a lock inside InnoDB.
This special lock is no longer necessary as the server is
closing the tables it needs to delete in ALTER TABLE.
Fixed by removing the special lock.
Note that this also reverses the fix for bug 17264 that deals with
another consequence of this special lock mode being used.

Fix for bug# 27950 - Init AUTOINC from delete_row().
Fix for bug# 28781 - Use value specified by MySQL, in update_row().
Summary of structural changes:
==============================
InnoDB needs to hold a table level lock for AUTOINC allocations to overcome
the non-determinism inherent in MySQL SBR for INSERT ... SELECT. In this fix
for simple INSERT statements (including multi-value inserts), we try and avoid
acquiring the special AUTOINC table level lock unless another transaction has
already reserved the AUTOINC table level lock, in which case we fall back
to the old behavior of acquiring the AUTOINC table level lock.
The max AUTOINC value is now read directly using the low level interface
of InnoDB.
by typecasting the variables before multiplying them, so that the result of
the multiplication is of type "unsigned long long".
I verified this fix by creating a sparse file of 6TB and forcing InnoDB to
use it without overwriting it with zeroes (by commenting the code that
overwrites :newraw files).
New type ullint is introduced with the sole purpose of shortening
"unsigned long long", please do not define it to something else than
"unsigned long long".
Approved by: Heikki
When creating an index containing a too long record, InnoDB would
dereference a NULL pointer when trying to determine the maximum row length.
innodb_check_for_record_too_big_error(): Replace the dict_table_t*
parameter with a Boolean flag. There is not always a dict_table_t object
when this function is called.
page_get_free_space_of_empty_noninline(): Move the definition and
declaration from row0mysql (!) to page0page. Make the signature
identical with page_get_free_space_of_empty().
create_clustered_index_when_no_primary(): Add the parameter "comp".
Remove unnecessary casts.
prebuilt->sql_stat_start. In an ALTER TABLE statement in the innodb_gis
test, an ut_ad() assertion failed, because no IX lock had been acquired
on the table, because prebuilt->sql_stat_start was inadvertently reset
to FALSE, by this function. This function was called via
ha_innobase::info() and mysql_prepare_alter_table().

thd_is_replication_slave_thread(), thd_has_edited_nontrans_tables():
Remove blank line between the function comment and the function
definition. There should be exactly one line between the return
type and the function comment, and this line should be one of
'', 'static', 'UNIV_INLINE', and 'extern "C"'.
longlong to long long because MYSQL_SYSVAR_LONGLONG marco expects long long
type.
Also change
((ulint)innobase_buffer_pool_size) / 1024
to
(ulint)(innobase_buffer_pool_size / 1024)
and remove comment which is no longer true.
Provided that innobase_buffer_pool_size is always 64bits these statements
are equivalent if ulint is 64 bit (well it will screw up if
innobase_buffer_pool_size is negative). And if ulint is 32 bit the later
variant gives a little more chance that the value will fit.

and adapt some things.
Note that ha_innodb.cc depends on mysql_tmpfile() being declared in
<mysql/plugin.h>. Until the function is declared there, you can
uncomment the buggy definition of mysql_tmpfile in ha_innodb.cc.
Remove storage/innobase/*/Makefile.am. The whole compilation is driven by
storage/innobase/Makefile.am and storage/innobase/plug.in.
plug.in: Declare InnoDB as a dynamic plugin.
ha_innodb.h: Remove the declarations of many global variables. The variables
are no longer directly referenced outside of storage/innobase.
trx_t: Add the field trx->duplicates.
trx_create(): Initialize the fields trx->active_trans and trx->duplicates.
innobase_query_is_update(): Remove. Consult trx->duplicates instead.
