SELECT PREVIOUS VALUE FOR sequence_name;
SELECT LASTVAL(sequence_name);
SHOW CREATE SEQUENCE sequence_name;
SHOW CREATE TABLE sequence_name;
CREATE TABLE sequence-structure ... SEQUENCE=1
ALTER TABLE sequence RENAME TO sequence2;
RENAME TABLE sequence TO sequence2;
DROP [TEMPORARY] SEQUENCE [IF EXISTS] sequence_names
Missing features
- SETVAL(value,sequence_name), to be used with replication.
- Check replication, including checking that sequence tables are marked
not transactional.
- Check that a commit happens for NEXT VALUE that changes table data (may
already work)
- ALTER SEQUENCE. ANSI SQL version of setval.
- Share identical sequence entries to not add things twice to table list.
- testing insert/delete/update/truncate/load data
- Run and fix Alibaba sequence tests (part of mysql-test/suite/sql_sequence)
- Write documentation for NEXT VALUE / PREVIOUS_VALUE
- NEXTVAL in DEFAULT
- Ensure that NEXTVAL in DEFAULT uses database from base table
- Two NEXTVAL for same row should give same answer.
- Oracle syntax sequence_table.nextval, without any FOR or FROM.
- Sequence tables are treated as 'not read constant tables' by SELECT; Would
be better if we would have a separate list for sequence tables so that
select doesn't know about them, except if refereed to with FROM.
Other things done:
- Improved output for safemalloc backtrack
- frm_type_enum changed to Table_type
- Removed lex->is_view and replaced with lex->table_type. This allows
use to more easy check if item is view, sequence or table.
- Added table flag HA_CAN_TABLES_WITHOUT_ROLLBACK, needed for handlers
that want's to support sequences
- Added handler calls:
- engine_name(), to simplify getting engine name for partition and sequences
- update_first_row(), to be able to do efficient sequence implementations.
- Made binlog_log_row() global to be able to call it from ha_sequence.cc
- Added handler variable: row_already_logged, to be able to flag that the
changed row is already logging to replication log.
- Added CF_DB_CHANGE and CF_SCHEMA_CHANGE flags to simplify
deny_updates_if_read_only_option()
- Added sp_add_cfetch() to avoid new conflicts in sql_yacc.yy
- Moved code for add_table_options() out from sql_show.cc::show_create_table()
- Added String::append_longlong() and used it in sql_show.cc to simplify code.
- Added extra option to dd_frm_type() and ha_table_exists to indicate if
the table is a sequence. Needed by DROP SQUENCE to not drop a table.
- Adding a new grammar file sql_yacc_ora.yy, which is currently
almost a full copy of sql_yacc.yy.
Note, it's now assumed that sql_yacc.yy and sql_yacc_ora.yy
use the same set of %token directives and exactly the same
%union directive.
These declarations should eventually be moved into a shared
included file, to make sure that sql_yacc.h and sql_yacc_ora.h
are compatible.
- Removing the "-p MYSQL" flag from cmake/bison.cmake, using
the %name-prefix directive inside sql_yacc.yy and sql_yacc_ora.yy instead
- Adding other CMake related changes to build sql_yacc_ora.o
form sql_yacc_ora.yy
- Adding NUMBER(M,N) as a synonym to DECIMAL(M,N) as the first
Oracle compatibility syntax understood in sql_mode=ORACLE.
- Adding prototypes to functions add_virtual_expression()
and handle_sql2003_note184_exception(), so they can be used
in both sql_yacc.yy and sql_yacc_ora.yy.
- Adding a new test suite compat/oracle, with the first test "type_number".
Use this:
./mtr compat/oracle.type_number # to run a single test
./mtr --suite=compat/oracle # to run the entire new suite
- Adding compat/oracle into the list of default suites,
so BuildBot can run it automatically on pushes.
dict_create_or_check_foreign_constraint_tables(): Change the warning
about the foreign key metadata table creation to a note.
Remove messages after metadata table creation. If the creation fails,
startup will abort with a message. Normally the creation succeeds on
bootstrap, and the messages would only be noise.
Remove the related suppressions from the tests.
This removes functionality of where ./mtr --mem /tmp/dir could be a directory.
Now MTR_MEM=/tmp/dir ./mtr is needed.
The case where MTR_MEM=/tmp/dir ./mtr --mem has the equivalent effect.

--mem works better as a pure flag, because it can be followed by command-line arguments (test names). If the option is allowed to have a value, the test name which directly follows it will be treated as the option value instead. It is possible to implement workarounds to avoid this, but they would not be completely reliable, and there is no practical purpose of such extension of functionality to justify them.
The standalone warning is not a sign of a problem, just of slowness,
so it should be added to global suppressions. If a real problem
happens, there will be other errors
* Revert "Make --mem a pure flag. If there is need to specifically set the location"
This reverts commit 716621db3f3055781e24f561325cec6eac181717.
* MDEV-11619: mtr: when --mem is pure flag, conflicts with $MTR_MEM
Conflicts occurs when MTR_MEM=/xxx/yy ./mtr --mem is invoked. Here
the --mem option overrides opt_mem leaving the default path to be chosen.
This change makes when MTR_MEM set, opt_mem, the flag, is also
set. Both the environment and flag can no be set without conflicting.

* MDEV-11619: if opt_mem is a path include it first
* MDEV-11619: MTR_MEM locations - don't follow symlinks
From Bjorn Munch it seems symlinks can confuse some
tests. Lets just avoid those.

Write only one encryption key to the checkpoint page.
Use 4 bytes of nonce. Encrypt more of each redo log block,
only skipping the 4-byte field LOG_BLOCK_HDR_NO which the
initialization vector is derived from.
Issue notes, not warning messages for rewriting the redo log files.
recv_recovery_from_checkpoint_finish(): Do not generate any redo log,
because we must avoid that before rewriting the redo log files, or
otherwise a crash during a redo log rewrite (removing or adding
encryption) may end up making the database unrecoverable.
Instead, do these tasks in innobase_start_or_create_for_mysql().
Issue a firm "Missing MLOG_CHECKPOINT" error message. Remove some
unreachable code and duplicated error messages for log corruption.
LOG_HEADER_FORMAT_ENCRYPTED: A flag for identifying an encrypted redo
log format.
log_group_t::is_encrypted(), log_t::is_encrypted(): Determine
if the redo log is in encrypted format.
recv_find_max_checkpoint(): Interpret LOG_HEADER_FORMAT_ENCRYPTED.
srv_prepare_to_delete_redo_log_files(): Display NOTE messages about
adding or removing encryption. Do not issue warnings for redo log
resizing any more.
innobase_start_or_create_for_mysql(): Rebuild the redo logs also when
the encryption changes.
innodb_log_checksums_func_update(): Always use the CRC-32C checksum
if innodb_encrypt_log. If needed, issue a warning
that innodb_encrypt_log implies innodb_log_checksums.
log_group_write_buf(): Compute the checksum on the encrypted
block contents, so that transmission errors or incomplete blocks can be
detected without decrypting.
Rewrite most of the redo log encryption code. Only remember one
encryption key at a time (but remember up to 5 when upgrading from the
MariaDB 10.1 format.)
options --log-slow-admin-statements, --log-queries-not-using-indexes and --log-slow-slave-statements have no effect if --log_slow_queries is not set
1. s/--log_slow_queries/--log-slow-queries/
2. disable log-slow-admin-statement/etc in mytr when doing mysqld --help
- created binlog_encryption test suite and added it to the default list
- moved some tests from rpl, binlog and multisource suites to extra
so that they could be re-used in different suites
- made minor changes in include files
The motivation for this is that Perl is moving towards not having
current directory ./ in @INC by default. This is causing
mysql-test-run.pl to fail in latest Debian Unstable:
https://lists.debian.org/debian-devel-announce/2016/08/msg00013.html
However, we have `use "lib"`, there is no need for current directory
in @INC, except for a gross hack. In mtr_cases.pm, there is a
`require "mtr_misc.pl"`, which hides mtr_misc.pl away in mtr_cases
namespace. And things only work because mysql-test-run.pl loads it
with a different name, `require "lib/mtr_misc.pl"`! (Perl will
`require` only once for each unique filename).
Fix this by only using `require` in main program, and referencing
functions with :: scope from other namespaces. For multi-use in
different namespaces, proper `use` modules should be used.

MDEV-10547: Test multi_update_innodb fails with InnoDB 5.7
The failure happened because 5.7 has changed the signature of
the bool handler::primary_key_is_clustered() const
virtual function ("const" was added). InnoDB was using the old
signature which caused the function not to be used.
MDEV-10550: Parallel replication lock waits/deadlock handling does not work with InnoDB 5.7
Fixed mutexing problem on lock_trx_handle_wait. Note that
rpl_parallel and rpl_optimistic_parallel tests still
fail.
MDEV-10156 : Group commit tests fail on 10.2 InnoDB (branch bb-10.2-jan)
Reason: incorrect merge
MDEV-10550: Parallel replication can't sync with master in InnoDB 5.7 (branch bb-10.2-jan)
Reason: incorrect merge
The issue was that when running with valgrind the wait for master_pos_Wait()
was not long enough.
This patch also fixes two other failures that could affect rpl_mdev6020:
- check_if_conflicting_replication_locks() didn't properly check domains
- 'did_mark_start_commit' was after signals to other threads was sent which could
get the variable read too early.
- Fixed typos
- Added --core-on-failure to mysql-test-run
- More DBUG_PRINT in viosocket.c
- Don't forget CLIENT_REMEMBER_OPTIONS for compressed slave protocol
- Removed not used stage variables
* MDEV-10294: Put testname into environment as MTR_TEST_NAME during MTR
