be consistent and don't include the table name into the error message,
no other CREATE TABLE error does it.
(the crash happened, because thd->lex->query_tables was NULL)
In original code, sometimes one got an automatic DEFAULT value in some cases, in other cases not.
For example:
create table t1 (a int primary key) - No default
create table t2 (a int, primary key(a)) - DEFAULT 0
create table t1 SELECT .... - Default for all fields, even if they where defined as NOT NULL
ALTER TABLE ... MODIFY could sometimes add an unexpected DEFAULT value.
The patch is quite big because we had some many test cases that used
CREATE ... SELECT or CREATE ... (...PRIMARY KEY(xxx)) which doesn't have an automatic DEFAULT anymore.
Other things:
- Removed warnings from InnoDB when waiting from semaphore (got this when testing things with --big)
Description: When querying a subset of columns from the information_schema.TABLES
Analysis: When information about tables is collected for statements like
"SELECT ENGINE FROM I_S.TABLES" we do not perform full-blown table opens
in SE, instead we only use information from table shares from the Table
Definition Cache or .FRMs. Still in order to simplify I_S implementation
mock TABLE objects are created from TABLE_SHARE during this process.
This is done by calling open_table_from_share() function with special
arguments. Since this function always increments "Opened_tables" counter,
calls to it can be mistakingly interpreted as full-blown table opens in SE.
Note that claim that "'SELECT ENGINE FROM I_S.TABLES' statement doesn't
use Table Cache" is nevertheless factually correct. But it misses the
point, since such statements a) don't use full-blown TABLE objects and
therefore don't do table opens b) still use Table Definition Cache.
Fix: We are now incrementing the counter when db_stat(i.e open flags for ha_open(
we have considered an optimization which would use TABLE objects from
Table Cache when available instead of constructing mock TABLE objects,
but found it too intrusive for stable releases.
main.information_schema: added a condition to the query to exclude perfschema tables
main.information_schema_all_engines: added a call to the include file to check for the presence of perfschema
Add missing REAP to the test.
A later test failed with strange incorrect values for COM_SELECT
in information_schema.global_status. Since global_status is updated
at the end of session activity, it seems appropriate to ensure that
all background connections have completed before accessing it.
(I checked that the original bug still triggers the test case after
the modification with REAP).

Bug#11756966 - 48958: STORED PROCEDURES CAN BE LEVERAGED TO BYPASS
DATABASE SECURITY
The problem was that CREATE PROCEDURE/FUCTION could be used to
check the existence of databases for which the user had no
privileges and therefore should not be allowed to see.
The reason was that existence of a given database was checked
before privileges. So trying to create a stored routine in
a non-existent database would give a different error than trying
to create a stored routine in a restricted database.
This patch fixes the problem by changing the order of the checks
for CREATE PROCEDURE/FUNCTION so that privileges are checked first.
This means that trying to create a stored routine in a
non-existent database and in a restricted database both will
give ER_DBACCESS_DENIED_ERROR error.
Test case added to grant.test.
- Make do_fill_table() use join_tab->cache_select->cond if it is present. When
join_tab->cache_select->cond is present, join_tab->select_cond doesn't have any
conditions that are usable for I_S optimizations.
support ha_innodb.so as a dynamic plugin.
* remove obsolete *,innodb_plugin.rdiff files
* s/--plugin-load=/--plugin-load-add=/
* MYSQL_PLUGIN_IMPORT glob_hostname[]
* use my_error instead of push_warning_printf(ER_DEFAULT)
* don't use tdc_size and tc_size in a module
update test cases (XtraDB is 5.6.14, InnoDB is 5.6.10)
* copy new tests over
* disable some tests for (old) InnoDB
* delete XtraDB tests that no longer apply
small compatibility changes:
* s/HTON_EXTENDED_KEYS/HTON_SUPPORTS_EXTENDED_KEYS/
* revert unnecessary InnoDB changes to make it a bit closer to the upstream
fix XtraDB to compile on Windows (both as a static and a dynamic plugin)
disable XtraDB on Windows (deadlocks) and where no atomic ops are available (e.g. CentOS 5)
storage/innobase/handler/ha_innodb.cc:
revert few unnecessary changes to make it a bit closer to the original InnoDB
storage/innobase/include/univ.i:
correct the version to match what it was merged from
mysql-test/r/acl_roles_show_grants.result:
one can do SHOW GRANTS for himself
mysql-test/t/acl_roles_set_role-table-column-priv.test:
correct error message
mysql-test/t/acl_roles_show_grants.test:
one can SHOW GRANTS for himself
sql/sql_acl.cc:
bugfixing:
* don't assign with && - it can shortcut and the second assignment won't be executed
* correct the test in check_grant_all_columns() - want_access should not be modified
*
sql/sql_cmd.h.OTHER:
add new commands at the end
sql/sql_db.cc:
don't call acl_get() if all privileges are already satisfied
(crashes when run with --skip-grants, because acl data stuctures aren't initialized)
sql/sql_parse.cc:
* test for current_user in get_current_user()
* map explicitly specified user@host to current_user
Change of user interface to be more logical and more in line with expectations
to work similar to old-style replication.
User can now explicitly choose in CHANGE MASTER whether binlog position is
taken into account (master_gtid_pos=current_pos) or not (master_gtid_pos=
slave_pos) when slave connects to master.
@@gtid_pos is replaced by three separate variables @@gtid_slave_pos (can
be set by user, replicated GTIDs only), @@gtid_binlog_pos (read only), and
@@gtid_current_pos (a combination of the two, most recent GTID within each
domain). mysql.rpl_slave_state is renamed to mysql.gtid_slave_pos to match.
This fixes MDEV-4474.
Merge of 10.0-mdev26 feature tree into 10.0-base.
Global transaction ID is prepended to each event group in the binlog.
Slave connect can request to start from GTID position instead of specifying
file name/offset of master binlog. This facilitates easy switch to a new
master.
Slave GTID state is stored in a table mysql.rpl_slave_state, which can be
InnoDB to get crash-safe slave state.
GTID includes a replication domain ID, allowing to keep track of distinct
positions for each of multiple masters.
Adjust full test suite to work with GTID.
Huge patch, mainly due to having to update .result file for all SHOW BINLOG
EVENTS and mysqlbinlog outputs, where the new GTID events pop up.
Everything was painstakingly checked to be still correct and valid .result
file updates.
