7bc6735736 MDEV-22401: Optimizer trace: multi-component range is not printed correctly
KEY_MULTI_RANGE::range_flag does not have correct flag bits for
per-endpoint flags (NEAR_MIN, NEAR_MAX, NO_MIN_RANGE, NO_MAX_RANGE).
It only has bits for flags that describe both endpoints.
So
- Document this.
- Switch optimizer trace to using {start|end}_key.flag values, instead.
  This fixes the bug.
- Switch records_in_column_ranges() to doing that too. (This used to
  work, because KEY_MULTI_RANGE::range_flag had correct flag value
  for the last key component, and EITS only uses one-component
  pseudo-indexes)

eb483c5181 Updated optimizer costs in multi_range_read_info_const() and sql_select.cc
- multi_range_read_info_const now uses the new records_in_range interface
- Added handler::avg_io_cost()
- Don't calculate avg_io_cost() in get_sweep_read_cost if avg_io_cost is
  not 1.0.  In this case we trust the avg_io_cost() from the handler.
- Changed test_quick_select to use TIME_FOR_COMPARE instead of
  TIME_FOR_COMPARE_IDX to align this with the rest of the code.
- Fixed bug when using test_if_cheaper_ordering where we didn't use
  keyread if index was changed
- Fixed a bug where we didn't use index only read when using order-by-index
- Added keyread_time() to HEAP.
  The default keyread_time() was optimized for blocks and not suitable for
  HEAP. The effect was the HEAP prefered table scans over ranges for btree
  indexes.
- Fixed get_sweep_read_cost() for HEAP tables
- Ensure that range and ref have same cost for simple ranges
  Added a small cost (MULTI_RANGE_READ_SETUP_COST) to ranges to ensure
  we favior ref for range for simple queries.
- Fixed that matching_candidates_in_table() uses same number of records
  as the rest of the optimizer
- Added avg_io_cost() to JT_EQ_REF cost. This helps calculate the cost for
  HEAP and temporary tables better. A few tests changed because of this.
- heap::read_time() and heap::keyread_time() adjusted to not add +1.
  This was to ensure that handler::keyread_time() doesn't give
  higher cost for heap tables than for normal tables. One effect of
  this is that heap and derived tables stored in heap will prefer
  key access as this is now regarded as cheap.
- Changed cost for index read in sql_select.cc to match
  multi_range_read_info_const(). All index cost calculation is now
  done trough one function.
- 'ref' will now use quick_cost for keys if it exists. This is done
  so that for '=' ranges, 'ref' is prefered over 'range'.
- scan_time() now takes avg_io_costs() into account
- get_delayed_table_estimates() uses block_size and avg_io_cost()
- Removed default argument to test_if_order_by_key(); simplifies code

f36ca142f7 Added page_range to records_in_range() to improve range statistics
Prototype change:
-  virtual ha_rows records_in_range(uint inx, key_range *min_key,
-                                   key_range *max_key)
+  virtual ha_rows records_in_range(uint inx, const key_range *min_key,
+                                   const key_range *max_key,
+                                   page_range *res)

The handler can ignore the page_range parameter. In the case the handler
updates the parameter, the optimizer can deduce the following:
- If previous range's last key is on the same block as next range's first
  key
- If the current key range is in one block
- We can also assume that the first and last block read are cached!
  This can be used for a better calculation of IO seeks when we
  estimate the cost of a range index scan.

The parameter is fully implemented for MyISAM, Aria and InnoDB.
A separate patch will update handler::multi_range_read_info_const() to
take the benefits of this change and also remove the double
records_in_range() calls that are not anymore needed.

1b5e5bdef3 MDEV-20306 Assert when converting encrypted Aria table to S3
Changes:
- maria_create() now uses a bit in the parameter flags to check if table
  should be encrypted instead of using maria_encrypted_tables.
- Don't encrypt tables that are to be converted to S3
- Added encrypted flag to ARIA_TABLE_CAPABILITIES
- maria_chk --description now prints if table is encrypted. Other
  operations is not allowed on encrypted tables.

d00f19e832 MDEV-371 Unique Index for long columns
This patch implements engine independent unique hash index.

Usage:- Unique HASH index can be created automatically for blob/varchar/test column whose key
 length > handler->max_key_length()
or it can be explicitly specified.

  Automatic Creation:-
   Create TABLE t1 (a blob unique);
  Explicit Creation:-
   Create TABLE t1 (a int , unique(a) using HASH);

Internal KEY_PART Representations:-
 Long unique key_info will have 2 representations.
 (lets understand this with an example create table t1(a blob, b blob , unique(a, b)); )

 1. User Given Representation:- key_info->key_part array will be similar to what user has defined.
 So in case of example it will have 2 key_parts (a, b)

 2. Storage Engine Representation:- In this case there will be only one key_part and it will point to
 HASH_FIELD. This key_part will be always after user defined key_parts.

 So:- User Given Representation          [a] [b] [hash_key_part]
                  key_info->key_part ----^
  Storage Engine Representation          [a] [b] [hash_key_part]
                  key_info->key_part ------------^

 Table->s->key_info will have User Given Representation, While table->key_info will have Storage Engine
 Representation.Representation can be changed into each other by calling re/setup_keyinfo_hash function.

Working:-

1. So when user specifies HASH_INDEX or key_length is > handler->max_key_length(), In mysql_prepare_create_table
One extra vfield is added (for each long unique key). And key_info->algorithm is set to HA_KEY_ALG_LONG_HASH.

2. In init_from_binary_frm_image values for hash_keypart is set (like fieldnr , field and flags)

3. In parse_vcol_defs, HASH_FIELD->vcol_info is created. Item_func_hash is used with list of Item_fields,
   When Explicit length is given by user then Item_left is used to concatenate Item_field values.

4. In ha_write_row/ha_update_row check_duplicate_long_entry_key is called which will create the hash key from
table->record[0] and then call ha_index_read_map , if we found duplicated hash , we will compare the result
field by field.

0ba6aaf030 MDEV-11415 Remove excessive undo logging during ALTER TABLE…ALGORITHM=COPY
If a crash occurs during ALTER TABLE…ALGORITHM=COPY, InnoDB would spend
a lot of time rolling back writes to the intermediate copy of the table.
To reduce the amount of busy work done, a work-around was introduced in
commit fd069e2bb3 in MySQL 4.1.8 and 5.0.2,
to commit the transaction after every 10,000 inserted rows.

A proper fix would have been to disable the undo logging altogether and
to simply drop the intermediate copy of the table on subsequent server
startup. This is what happens in MariaDB 10.3 with MDEV-14717,MDEV-14585.
In MariaDB 10.2, the intermediate copy of the table would be left behind
with a name starting with the string #sql.

This is a backport of a bug fix from MySQL 8.0.0 to MariaDB,
contributed by jixianliang <271365745@qq.com>.

Unlike recent MySQL, MariaDB supports ALTER IGNORE. For that operation
InnoDB must for now keep the undo logging enabled, so that the latest
row can be rolled back in case of an error.

In Galera cluster, the LOAD DATA statement will retain the existing
behaviour and commit the transaction after every 10,000 rows if
the parameter wsrep_load_data_splitting=ON is set. The logic to do
so (the wsrep_load_data_split() function and the call
handler::extra(HA_EXTRA_FAKE_START_STMT)) are joint work
by Ji Xianliang and Marko Mäkelä.

The original fix:

Bug#17479594 AVOID INTERMEDIATE COMMIT WHILE DOING ALTER TABLE ALGORITHM=COPY

Problem:

During ALTER TABLE, we commit and restart the transaction for every
10,000 rows, so that the rollback after recovery would not take so long.

Fix:

Suppress the undo logging during copy alter operation. If fts_index is
present then insert directly into fts auxiliary table rather
than doing at commit time.

ha_innobase::num_write_row: Remove the variable.

ha_innobase::write_row(): Remove the hack for committing every 10000 rows.

row_lock_table_for_mysql(): Remove the extra 2 parameters.

lock_get_src_table(), lock_is_table_exclusive(): Remove.

84726906c9 MDEV-10177 Invisible Columns and Invisible Index
Feature Definition:-

This feature adds invisible column functionality to server.
There is 4 level of "invisibility":

1. Not invisible (NOT_INVISIBLE) — Normal columns created by the user

2. A little bit invisible (USER_DEFINED_INVISIBLE) — columns that the
    user has marked invisible. They aren't shown in SELECT * and they
    don't require values in INSERT table VALUE (...). Otherwise
    they behave as normal columns.

3. More invisible (SYSTEM_INVISIBLE) — Can be queried explicitly,
    otherwise invisible from everything. Think ROWID sytem column.
    Because they're invisible from ALTER TABLE and from CREATE TABLE
    they cannot be created or dropped, they're created by the system.
    User cant not create a column name which is same as of
    SYSTEM_INVISIBLE.

4. Very invisible (COMPLETELY_INVISIBLE) — as above, but cannot be
    queried either. They can only show up in EXPLAIN EXTENDED (might
    be possible for a very invisible indexed virtual column) but
    otherwise they don't exist for the user.If user creates a columns
    which has same name as of COMPLETELY_INVISIBLE then
    COMPLETELY_INVISIBLE column is renamed again. So it is completely
    invisible from user.

Invisible Index(HA_INVISIBLE_KEY):-
   Creation of invisible columns require a new type of index which
   will be only visible to system. User cant see/alter/create/delete
   this index. If user creates a index which is same name as of
   invisible index then it will be renamed.

Syntax Details:-

  Only USER_DEFINED_INVISIBLE column can be created by user. This
  can be created by adding INVISIBLE suffix after column definition.

  Create table t1( a int invisible, b int);

Rules:-
  There are some rules/restrictions related to use of invisible columns
  1. All the columns in table cant be invisible.
     Create table t1(a int invisible); \\error
     Create table t1(a int invisible, b int invisble); \\error
  2. If you want invisible column to be NOT NULL then you have to supply
     Default value for the column.
     Create table t1(a int, b int not null); \\error
  3. If you create a view/create table with select * then this wont copy
     invisible fields. So newly created view/table wont have any invisible
     columns.
     Create table t2 as select * from t1;//t2 wont have t1 invisible column
     Create view v1 as select * from t1;//v1 wont have t1 invisible column
  4. Invisibility wont be forwarded to next table in any case of create
     table/view as select */(a,b,c) from table.
     Create table t2 as select a,b,c from t1; // t2 will have t1 invisible
                           // column(b), but this wont be invisible in t2
     Create view v1 as select a,b,c from t1; // v1 will have t1 invisible
                           // column(b), but this wont be invisible in v1

Implementation Details:-
  Parsing:- INVISIBLE_SYM is added into vcol_attribute(so its like unique
      suffix), It is also added into keyword_sp_not_data_type so that table
      can have column with name invisible.
  Implementation detail is given by each modified function/created function.
   (Some function are left as they were self explanatory)
   (m= Modified, n= Newly Created)

  mysql_prepare_create_table(m):- Extra checks for invisible columns are
  added. Also some DEBUG_EXECUTE_IF are also added for test cases.

  mysql_prepare_alter_table(m):- Now this will drop all the
  COMPLETELY_INVISIBLE column and HA_INVISIBLE_KEY index. Further
  Modifications are made to stop drop/change/delete of SYSTEM_INVISIBLE
  column.

  build_frm_image(m):- Now this allows incorporating field_visibility
  status into frm image. To remain compatible with old frms
  field_visibility info will be only written when any of the field is
  not NOT_INVISIBLE.

  extra2_write_additional_field_properties(n):- This will write field
  visibility info into buffer. We first write EXTRA2_FIELD_FLAGS into
  buffer/frm , then each next char will have field_visibility for each
  field.

  init_from_binary_frm_image(m):- Now if we get EXTRA2_FIELD_FLAGS,
  then we will read the next n(n= number of fields) chars and set the
  field_visibility. We also increment
  thd->status_var.feature_invisible_columns. One important thing to
  note if we find out that key contains a field whose visibility is
  > USER_DEFINED_INVISIBLE then , we declare this key as invisible
  key.

  sql_show.cc is changed accordingly to make show table, show keys
  correct.

  mysql_insert(m):- If we get to know that we are doing insert in
  this way insert into t1 values(1,1); without explicitly specifying
  columns, then we check for if we have invisible fields if yes then
  we reset the whole record, Why ? Because first we want hidden columns
  to get default/null value. Second thing auto_increment has property
  no default and no null which voilates invisible key rule 2, And
  because of this it was giving error. Reseting table->record[0]
  eliminates this issue. More info put breakpoint on handler::write_row
  and see auto_increment value.

  fill_record(m):- we continue loop if we find invisible column because
  this is already reseted/will get its value if it is default.

Test cases:- Since we can not directly add > USER_DEFINED_INVISIBLE
  column then I have debug_dbug to create it in mysql_prepare_create_table.

Working features:
CREATE OR REPLACE [TEMPORARY] SEQUENCE [IF NOT EXISTS] name
    [ INCREMENT [ BY | = ] increment ]
    [ MINVALUE [=] minvalue | NO MINVALUE ]
    [ MAXVALUE [=] maxvalue | NO MAXVALUE ]

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.

89d80c1b0b Fix many -Wconversion warnings.
Define my_thread_id as an unsigned type, to avoid mismatch with
ulonglong.  Change some parameters to this type.

Use size_t in a few more places.

Declare many flag constants as unsigned to avoid sign mismatch
when shifting bits or applying the unary ~ operator.

When applying the unary ~ operator to enum constants, explictly
cast the result to an unsigned type, because enum constants can
be treated as signed.

In InnoDB, change the source code line number parameters from
ulint to unsigned type. Also, make some InnoDB functions return
a narrower type (unsigned or uint32_t instead of ulint;
bool instead of ibool).

192678e7bf MDEV-5241: Collation incompatibilities with MySQL-5.6
- Character set code & tests from Alexander Barkov
- Integration with ALTER TABLE, REPAIR and open_table from Monty

The problem was that MySQL 5.6 added some croatian and vitanamese character set collations that are incompatible with MariaDB.

The fix is to move the MariaDB conflicting collation numbers out of the region that MySQL is likely to use.
mysql_upgrade, REPAIR TABLE or ALTER TABLE will fix the collations.
If one tries to access and old incompatible table, one will get the error "Table upgrade required...."
After this patch, MariaDB supports all the MySQL character set collations and the old MariaDB croatian collations, which are closer to the latest standard than the MySQL versions.

New character sets:
ucs2_croatian_mysql561_uca_ci
utf8_croatian_mysql561_uca_ci
utf16_croatian_mysql561_uca_ci
utf32_croatian_mysql561_uca_ci
utf8mb4_croatian_mysql561_uca_ci

Other things:
- Fixed some compiler warnings
- mysql_upgrade prints information about repaired tables.
- Increased version number

VERSION:
  Increased VERSION number
client/mysqlcheck.c:
  Print repaired table name when using --verbose
include/m_ctype.h:

c1615df32c Bug#13635833: MULTIPLE CRASHES IN FOREIGN KEY CODE WITH CONCURRENT DDL/DML
There are two threads.  In one thread, dml operation is going on 
involving cascaded update operation.  In another thread, alter 
table add foreign key constraint is happening.  Under these 
circumstances, it is possible for the dml thread to access a 
dict_foreign_t object that has been freed by the ddl thread.  
The debug sync test case provides the sequence of operations.  
Without fix, the test case will crash the server (because of 
newly added assert).  With fix, the alter table stmt will return 
an error message.

247ada63af Bug#12547647 UPDATE LOGGING COULD EXCEED LOG PAGE SIZE
This fix was accidentally pushed to mysql-5.1 after the 5.1.59 clone-off in
bzr revision id marko.makela@oracle.com-20110829081642-z0w992a0mrc62s6w
with the fix of Bug#12704861 Corruption after a crash during BLOB update
but not merged to mysql-5.5 and upwards.

In the Barracuda formats, the clustered index record no longer
contains a prefix of off-page columns. Because of this, the undo log
must contain these prefixes, so that purge and multi-versioning will
continue to work. However, this also means that an undo log record can
become too big to fit in an undo log page. (It is a limitation of the
undo log that undo records cannot span across multiple pages.)

In case the checks for undo log size fail when CREATE TABLE or CREATE
INDEX is executed, we need a fallback that blocks a modification
operation when the undo log record would exceed the maximum size.

trx_undo_free_last_page_func(): Renamed from trx_undo_free_page_in_rollback().
Define the trx_t parameter only in debug builds.

trx_undo_free_last_page(): Wrapper for trx_undo_free_last_page_func().
Pass the trx_t parameter only in debug builds.

trx_undo_truncate_end_func(): Renamed from trx_undo_truncate_end().
Define the trx_t parameter only in debug builds. Rewrite a for(;;) loop
as a while loop for clarity.

trx_undo_truncate_end(): Wrapper for from trx_undo_truncate_end_func().
Pass the trx_t parameter only in debug builds.

trx_undo_erase_page_end(): Return TRUE if the page was non-empty

95fa7fab3b Fix bug #11830883, SUPPORT "CORRUPTED" BIT FOR INNODB TABLES AND INDEXES.
Also addressed issues in bug #11745133, where we could mark a table
corrupted instead of crashing the server when found a corrupted buffer/page
if the table created with innodb_file_per_table on.

5c70f813f3 Added HA_ERR_DISK_FULL handler error
Original code by Zardosht Kasheff

sql/handler.cc:
  Added HA_ERR_DISK_FULL and ENOSPC (for handler that uses normal errno).
  This sets 'fatal_error' to ensure that the error is logged to err file (which hopefully is on another disk...)

b12e3796dc Fix for lp:711565 "Index Condition Pushdown can make a thread hold MyISAM locks as well as be unKILLable for long time"
- In Maria/MyISAM: Release/re-acquire locks to give queries that wait on them a chance to make progress
- In Maria/MyISAM: Change from numeric constants to ICP_RES values.
- In Maria: Do check index condition in maria_rprev() (was lost in the merge/backport?)
- In Maria/MyISAM/XtraDB: Check if the query was killed, and return immediately if it was.

and 'THREAD_SAFE_CLIENT'.
  
As of MySQL 5.5, we no longer support non-threaded
builds.   This patch removes all references to the
obsolete THREAD and THREAD_SAFE_CLIENT preprocessor
symbols.  These were used to distinguish between
threaded and non-threaded builds.

20acfbf30d Fix for: LP #634955: Assert in _ma_update_at_original_place()
Added locking of lock mutex when updating status in external_unlock() for Aria and MyISAM tables.
Fixed that 'source' command doesn't cause mysql command line tool to exit on error.
DEBUG_EXECUTE() and DEBUG_EVALUATE_IF() should not execute things based on wildcards. (Allows one to run --debug with mysql-test-run scripts that uses @debug)
Fixed several core dump, deadlock and crashed table bugs in handling of LOCK TABLE with MERGE tables:
- Added priority of locks to avoid crashes with MERGE tables.
- Added thr_lock_merge() to allow one to merge two results of thr_lock().
Fixed 'not found row' bug in REPLACE with Aria tables.
Mark MyISAM tables that are part of MERGE with HA_OPEN_MERGE_TABLE and set the locks to have priority THR_LOCK_MERGE_PRIV.
- By sorting MERGE tables last in thr_multi_unlock() it's safer to release and relock them many times (can happen when TRIGGERS are created)
Avoid printing (null) in debug file (to easier find out wrong NULL pointer usage with %s).



client/mysql.cc:
  Fixed that 'source' command doesn't cause mysql command line tool to exit on error.
client/mysqltest.cc:
  Don't send NULL to fn_format(). (Can cause crash on Solaris when using --debug)
dbug/dbug.c:
  DEBUG_EXECUTE() and DEBUG_EVALUATE_IF() should not execute things based on wildcards.
include/my_base.h:
  Added flag to signal if one opens a MERGE table.
  Added extra() command to signal that one is not part of a MERGE table anymore.
include/thr_lock.h:
  Added priority for locks (needed to fix bug in thr_lock when using MERGE tables)
  Added option to thr_unlock() if get_status() should be called.
  Added prototype for thr_merge_locks().
mysql-test/mysql-test-run.pl:
  Ignore crashed table warnings for tables named 'crashed'.
mysql-test/r/merge.result:
  Renamed triggers to make debugging easier.
  Added some CHECK TABLES to catch errors earlier.
  Additional tests.
mysql-test/r/merge_debug.result:
  Test of error handling when reopening MERGE tables.
mysql-test/r/udf_query_cache.result:
  Added missing flush status
mysql-test/suite/parts/r/partition_repair_myisam.result:
  Update results
mysql-test/t/merge.test:
  Renamed triggers to make debugging easier.
  Added some CHECK TABLES to catch errors earlier.
  Additional tests.
mysql-test/t/merge_debug.test:
  Test of error handling when reopening MERGE tables.
mysql-test/t/udf_query_cache.test:
  Added missing flush status
mysys/my_getopt.c:
  Removed not used variable
mysys/my_symlink2.c:
  Changed (null) to (NULL) to make it easier to find NULL arguments to DBUG_PRINT() functions.
  (On linux, NULL to sprintf is printed 'null')
mysys/thr_lock.c:
  Added priority of locks to avoid crashes with MERGE tables.
  Added thr_lock_merge() to allow one to merge two results of thr_lock().
  - This is needed for MyISAM as all locked table must share the same status. If not, you will not see newly inserted rows in other instances of the table.
  If calling thr_unlock() with THR_UNLOCK_UPDATE_STATUS, call update_status() and restore_status() for the locks. This is needed in some rare cases where we call thr_unlock() followed by thr_lock() without calling external_unlock/external_lock in between.
  Simplify loop in thr_multi_lock().
  Added 'start_trans', which is called at end of thr_multi_lock() when all locks are taken.
  - This was needed by Aria to ensure that transaction is started when we got all locks, not at get_status(). Without this, some rows could not be visible when we lock two tables at the same time, causing REPLACE using two tables to fail unexpectedly.
sql/handler.cc:
  Add an assert() in handler::print_error() for "impossible errors" (like table is crashed) when --debug-assert-if-crashed-table is used.
sql/lock.cc:
  Simplify mysql_lock_tables() code if get_lock_data() returns 0 locks.
  Added new parameter to thr_multi_unlock()
  In mysql_unlock_read_tables(), call first externa_unlock(), then thr_multi_unlock();  This is same order as we do in mysql_unlock_tables().
  Don't abort locks in mysql_lock_abort() for merged tables when a MERGE table is deleted; Would cause a spin lock.
  Added call to thr_merge_locks() in mysql_lock_merge() to ensure consistency in thr_locks().
  - New locks of same type and table is stored after the old lock to ensure that we get the status from the original lock.
sql/mysql_priv.h:
  Added debug_assert_if_crashed_table
sql/mysqld.cc:
  Added --debug-assert-if-crashed-table
sql/parse_file.cc:
  Don't print '(null)' in DBUG_PRINT of no dir given
sql/set_var.cc:
  Increase default size of buffer for @debug variable.
sql/sql_base.cc:
  In case of error from reopen_table() in reopen_tables(), call unlock_open_table() and restart loop.
  - This fixed bug when we twice deleted same table from open_cache.
  Don't take name lock for already name locked table in open_unireg_entry().
  - Fixed bug when doing repair in reopen_table().
  - In detach_merge_children(), always detach if 'clear_refs' is given. We can't trust parent->children_attached as this function can be called twice, first time with clear_refs set to 0.
sql/sql_class.cc:
  Changed printing of (null) to "" in set_thd_proc_info()
sql/sql_parse.cc:
  Added DBUG
sql/sql_trigger.cc:
  Don't call unlink_open_table() if reopen_table() fails as the table may already be freed.
storage/maria/ma_bitmap.c:
  Fixed DBUG_ASSERT() in allocate_tail()
storage/maria/ma_blockrec.c:
  Fixed wrong calculation of row length for very small rows in undo_row_update().
  - Fixes ASSERT() when doing undo.
storage/maria/ma_blockrec.h:
  Added _ma_block_start_trans() and _ma_block_start_trans_no_versioning()
storage/maria/ma_locking.c:
  Call _ma_update_status_with_lock() when releasing write locks.
  - Fixes potential problem with updating status without the proper lock.
storage/maria/ma_open.c:
  Changed to use start_trans() instead of get_status() to ensure that we see all rows in all locked tables when we got the locks.
  - Fixed 'not found row' bug in REPLACE with Aria tables.
storage/maria/ma_state.c:
  Added _ma_update_status_with_lock() and _ma_block_start_trans().
  This is to ensure that we see all rows in all locked tables when we got the locks.
storage/maria/ma_state.h:
  Added _ma_update_status_with_lock()
storage/maria/ma_write.c:
  More DBUG_PRINT
storage/myisam/mi_check.c:
  Fixed error message
storage/myisam/mi_extra.c:
  Added HA_EXTRA_DETACH_CHILD:
  - Detach MyISAM table to not be part of MERGE table (remove flag & lock priority).
storage/myisam/mi_locking.c:
  Call mi_update_status_with_lock() when releasing write locks.
  - Fixes potential problem with updating status without the proper lock.
  Change to use new HA_OPEN_MERGE_TABLE flag to test if MERGE table.
  Added mi_fix_status(), called by thr_merge().
storage/myisam/mi_open.c:
  Added marker if part of MERGE table.
  Call mi_fix_status() in thr_lock() for transactional tables.
storage/myisam/myisamdef.h:
  Change my_once_flag to uint, as it stored different values than just 0/1
  Added 'open_flag' to store state given to mi_open()
storage/myisammrg/ha_myisammrg.cc:
  Add THR_LOCK_MERGE_PRIV to THR_LOCK_DATA to get MERGE locks sorted after other types of locks.
storage/myisammrg/myrg_locking.c:
  Remove windows specific code.
storage/myisammrg/myrg_open.c:
  Use HA_OPEN_MERGE_TABLE to mi_open().
  Set HA_OPEN_MERGE_TABLE for linked MyISAM tables.
storage/xtradb/buf/buf0buf.c:
  Fixed compiler warning
storage/xtradb/buf/buf0lru.c:
  Initialize variable that could be used not initialized.

ac6b3c4430 few small MySQL bugs/issues that impact the engines, as discussed in the SE summit
* remove handler::index_read_last()
* create handler::keyread_read_time() (was get_index_only_read_time() in opt_range.cc)
* ha_show_status() allows engine's show_status() to fail
* remove HTON_FLUSH_AFTER_RENAME
* fix key_cmp_if_same() to work for floats and doubles
* set table->status in the server, don't force engines to do it

  index searches as handler_read_* calls.
sql/ha_partition.cc:
  compensate for handler incrementing status counters -
  we want to count only calls to underlying engines
sql/handler.h:
  inline methods moved to sql_class.h
sql/key.cc:
  simplify the check
sql/opt_range.cc:

sql/item_sum.h:
  Add prototypes with the appropriate linkage as otherwise they
  are distinct.
sql/mysqld.cc:
  Wrap functions in C linkage mode.
sql/opt_range.cc:
  C language linkage is ignored for class member functions.
sql/partition_info.cc:
  Add wrapper functions with C linkage for class member functions.
sql/rpl_utility.h:
  Use helper macro and fix indentation.
sql/sql_class.cc:

d77e3cde5f When one does a drop table, the indexes are not flushed to disk before drop anymore (with MyISAM/Maria)
myisam-recover options changed from OFF to 'DEFAULT' to get less change of data loss when using MyISAM.
(The disadvantage is that changed MyISAM tables will be checked at access time; Use --myisam-recover=OFF for old behavior)
Don't call extra(HA_EXTRA_FORCE_REOPEN) in ALTER TABLE if table is locked as this will mark table as crashed!
Added assert to detect if we accidently would use MyISAM versioning in MySQL

include/my_base.h:
  Mark NOT_USED as USED, as we now use this as a flag to not call extra()
mysql-test/mysql-test-run.pl:
  Don't write all options when there is something wrong with the arguments
mysql-test/r/sp-destruct.result:
  Add missing flush of mysql.proc (as the test copied live tables)

  myisam-recover options changed to 'default'
mysql-test/r/view.result:
  Don't show create time in result
mysql-test/suite/maria/t/maria-recovery2-master.opt:

sql/mysql_priv.h:
  Added marker if table was deleted to argument list
sql/mysqld.cc:

sql/sql_base.cc:
  Mark if table is going to be deleted
sql/sql_delete.cc:
  Mark if table is going to be deleted
sql/sql_table.cc:
  Mark if table is going to be deleted
  Don't call extra(HA_EXTRA_FORCE_REOPEN) in ALTER TABLE if table is locked as this will mark table as crashed!
sql/table.cc:
  Signal to handler if table is getting deleted as part of getting droped from table cache.
sql/table.h:
  Added marker if table is going to be deleted.
storage/maria/ha_maria.cc:
  Don't search for transaction handler if file is not transactional or outside of transaction
  (Fixed possible core dump)

  Don't write changed information if table is going to be deleted.
storage/maria/ma_close.c:
  Don't write changed information if table is going to be deleted.
storage/maria/ma_extra.c:
  Mark tables that are deleted as crased, to ensure good behavior on restart if we suddenly crash.
storage/maria/ma_locking.c:
  Cleanup
storage/maria/ma_recovery.c:
  We need trnman to be inited during redo phase (to be able to open tables checked with maria_chk)

message:
  WL#4144 - Lock MERGE engine children.
  Committing a version of the patch merged with WL#3726
  on behalf of Ingo.

  Step #1: Move locking from parent to children.

  MERGE children are now left in the query list of tables
  after inserted there in open_tables(). So they are locked
  by lock_tables() as all other tables are.

  The MERGE parent does not store locks any more. It appears
  in a MYSQL_LOCK with zero lock data. This is kind of a "dummy"
  lock.

  All other lock handling is also done directly on the children.
  To protect against parent or child modifications during LOCK
  TABLES, the children are detached after every statement and
  attached before every statement, even under LOCK TABLES.

  The children table list is removed from the query list of tables
  on every detach and on close of the parent.

  Step #2: Move MERGE specific functionality from SQL layer
  into table handler.

  Functionality moved from SQL layer (mainly sql_base.cc)
  to the table handler (ha_myisammrg.cc).

  Unnecessary code is removed from the SQL layer.

  Step #3: Moved all MERGE specific members from TABLE
  to ha_myisammrg.

  Moved members from TABLE to ha_myisammrg.
  Renamed some mebers.
  Fixed comments.

  Step #4: Valgrind and coverage testing

  Valgrind did not uncover new problems.
  Added purecov comments.

  Added a new test for DATA/INDEX DIRECTORY options.
  Changed handling of ::reset() for non-attached children.
  Fixed the merge-big test.

  Step #5: Fixed crashes detected during review
  Changed detection when to attach/detach.
  Added new tests.

Backport also the fix for Bug#44040 "MySQL allows creating a 
MERGE table upon VIEWs but crashes when using it"

342553252f Fix for BUG#18828 - If InnoDB runs out of undo slots,
it returns misleading 'table is full'

Innodb returns a misleading error message "table is full" 
when the number of active concurrent transactions is greater
than 1024.

Fixed by adding errorcode "ER_TOO_MANY_CONCURRENT_TRXS" to the
error codes. Innodb should return HA_TOO_MANY_CONCURRENT_TRXS
to mysql which is then mapped to ER_TOO_MANY_CONCURRENT_TRXS


Note: testcase is not written as this was reproducible only by
      changing innodb code.

extra/perror.c:
  Add error number and message for HA_ERR_TOO_MANY_CONCURRENT_TRXS
include/my_base.h:
  Add error number and message for HA_ERR_TOO_MANY_CONCURRENT_TRXS

00aa5ad58a Bug#39370: wrong output for error code 153
Add all HA error numbers and descriptions to perror.

Add reminder to header.

This is already fixed in smarter ways in future codebases, and this 
codebase is unlikely to change, since new development is forbidden
here.

058916ae02 Fix for bug#39226 Maria: crash with FLUSH TABLES WITH READ LOCK after LOCK TABLES
- The problem was that we didn't inform the handler that we are going to close tables that are locked and may have (at least in Maria) be part of an active transaction.
Fix for Bug#39227 Maria: crash with ALTER TABLE PARTITION
Fix for Bug #39987 main.partition_not_windows fails under debug build
Fixed some compiler errors & warnings found by pushbuild

include/my_base.h:
  Added HA_EXTRA_PREPARE_FOR_FORCED_CLOSE for signaling the handler that the file will be forced closed
include/my_global.h:
  Removed 'register' from 'swap_variables' as this gives a warnings when the variables are structs. Compilers should also now be smart enough to figure out this themselves
mysql-test/r/subselect_debug.result:
  Reset value of the debug variable;  Without setting this the subselect_innodb test will fail when run after this one
mysql-test/suite/maria/r/maria.result:
  Merged test with myisam.test
  Added tests for new fixed bugs
mysql-test/suite/maria/t/maria.test:
  Merged test with myisam.test
  Added tests for new fixed bugs
mysql-test/t/subselect_debug.test:
  Reset value of the debug variable;  Without setting this the subselect_innodb test will fail when run after this one
mysys/my_uuid.c:
  Fixed compiler error on windows
sql/ha_partition.cc:
  Added support for the new extra flag: HA_EXTRA_PREPARE_FOR_FORCED_CLOSE (Bug #39226)
  Ensure that we call extra() for HA_EXTRA_PREPARE_FOR_DROP (Bug#39227)
sql/mysqld.cc:
  Fix for Bug #39987 main.partition_not_windows fails under debug build
  The problem was that when compiling for purify/valgrind realpath() is not used, which causes test_if_data_home_dir to fail when it shouldn't
sql/sql_base.cc:
  Call HA_EXTRA_PREPARE_FOR_FORCED_CLOSE for tables that are locked but we are going to force close without doing a commit
sql/sql_parse.cc:
  More DBUG_PRINT. Fixed comments
storage/maria/ma_extra.c:
  If HA_EXTRA_PREPARE_FOR_FORCED_CLOSE is called and the table is part of a transaction, remove the table from beeing part of a transaction.
  This is safe as this is only used as part of flush tables or when the table is not part of a transaction
storage/myisam/mi_open.c:
  Indentation fix
unittest/mysys/waiting_threads-t.c:
  Remove not needed 'volatile' to get rid of compiler warnings on windows
