page_cur_dtuple_cmp(): Take DESC index fields into account also when
comparing a NULL value in a ROW_FORMAT≠REDUNDANT record.
Thanks to Elena Stepanova for finding this bug.
Don't allow the referencing key column from NULL TO NOT NULL
when
1) Foreign key constraint type is ON UPDATE SET NULL
2) Foreign key constraint type is ON DELETE SET NULL
3) Foreign key constraint type is UPDATE CASCADE and referenced
column declared as NULL
Don't allow the referenced key column from NOT NULL to NULL
when foreign key constraint type is UPDATE CASCADE
and referencing key columns doesn't allow NULL values
get_foreign_key_info(): InnoDB sends the information about
nullability of the foreign key fields and referenced key fields.
fk_check_column_changes(): Enforce the above rules for COPY
algorithm
innobase_check_foreign_drop_col(): Checks whether the dropped
column exists in existing foreign key relation
innobase_check_foreign_low() : Enforce the above rules for
INPLACE algorithm
dict_foreign_t::check_fk_constraint_valid(): This is used
by CREATE TABLE statement to check nullability for foreign
key relation.
Ever since commit 685d958e38
some Perl code in the test mariabackup.huge_lsn is writing names of
non-existing files to the InnoDB redo log and testing the recovery.
We do not need any debug instrumentation to duplicate that test.
This is loosely based on the InnoDB changes in
mysql/mysql-server@97fd8b1b69
that I had developed in 2015 or 2016.
For each B-tree key field, we will allow a flag ASC/DESC to be associated.
When PRIMARY KEY fields are internally appended to secondary indexes,
the ASC/DESC attribute will be inherited, so that covering index scans
will work as expected.
Note: Until the subsequent commit, the DESC attribute will be ignored
(no HA_REVERSE_SORT flag will be written to .frm files).
dict_field_t::descending: A new flag to denote descending order.
cmp_data(), cmp_dfield_dfield(): Add a new parameter descending.
cmp_dtuple_rec(), cmp_dtuple_rec_with_match(): Add a parameter "index".
dtuple_coll_eq(): Replaces dtuple_coll_cmp().
cmp_dfield_dfield_eq_prefix(): Replaces cmp_dfield_dfield_like_prefix().
dict_index_t::is_btree(): Check whether the index is a regular
B-tree index (not SPATIAL, FULLTEXT, or the ibuf.index,
or a corrupted index.
btr_cur_search_to_nth_level_func(): Only attempt to use
the adaptive hash index if index->is_btree().
This function may also be invoked on ibuf.index, and
cmp_dtuple_rec_with_match_bytes() will no longer work on ibuf.index
because it assumes that the index and record fields exactly match.
The ibuf.index is a special variadic index tree.
Thanks to Thirunarayanan Balathandayuthapani for fixing some bugs:
MDEV-27439, MDEV-27374/MDEV-27445.
Dead code cleanup:
part_info->num_parts usage was wrong and working incorrectly in
mysql_drop_partitions() because num_parts is already updated in
prep_alter_part_table(). We don't have to update part_info->partitions
because part_info is destroyed at alter_partition_lock_handling().
Cleanups:
- DBUG_EVALUATE_IF() macro replaced by shorter form DBUG_IF();
- Typo in ER_KEY_COLUMN_DOES_NOT_EXITS.
Refactorings:
- Splitted write_log_replace_delete_frm() into write_log_delete_frm()
and write_log_replace_frm();
- partition_info via DDL_LOG_STATE;
- set_part_info_exec_log_entry() removed.
DBUG_EVALUATE removed
DBUG_EVALUTATE was only added for consistency together with
DBUG_EVALUATE_IF. It is not used anywhere in the code.
DBUG_SUICIDE() fix on release build
On release DBUG_SUICIDE() was statement. It was wrong as
DBUG_SUICIDE() is used in expression context.
Includes:
MDEV-17302 Add support for ALTER USER command in prepared statement
and
MDEV-17673 main.cte_recursive fails in bb-10.4-ps branch in --ps
Set correct SELECT_LEX linkage for recursive CTEs.
Do not delegate this job to TABLE_LIST::set_as_with_table,
because it is only run on prepare, while With_element::move_anchors_ahead
is run both on prepare and execute (fix by Igor)
This was introduced in 1a7a018939
MDEV-16557 Remove INNOBASE_SHARE::idx_trans_tbl
ha_innobase::innobase_get_index: remove incorrect assertion.
Index nullability is checked in subsequent ifs.
Closes#1079
ha_innobase::prepare_inplace_alter_table(): check max column length for every
index in a table, not just added in this particular ALTER TABLE with ADD INDEX ones.
The test innodb.log_file_name_debug failed to ensure that
the bogus redo log record that its debug injection emitted
would be consumed by a redo log checkpoint before running a
subsequent test, which could perform crash recovery.
Add an extra shutdown to ensure that a redo log checkpoint is
generated. In this way, the following will succeed:
./mtr --no-reorder innodb.log_file_name_debug innodb.read_only_recovery
Problem:
=======
During validation of missing tablespace, missing tablespace id is
being compared with hash table of redo logs (recv_sys->addr_hash). But if the
hash table ran out of memory then there is a possibility that it will not contain
the redo logs of all tablespace. In that case, Server will load the InnoDB
even though there is a missing tablespace.
Solution:
========
If the recv_sys->addr_hash hash table ran out of memory then InnoDB needs
to scan the remaining redo log again to validate the missing tablespace.
Import the changes to innodb.innodb-index innodb.innodb-index-debug
Note: As noted in MDEV-13613, due to the behaviour change in MDEV-11114,
DROP COLUMN will not imply DROP/ADD PRIMARY/UNIQUE KEY, like it does
in MySQL. The tests have been adjusted accordingly.
innodb_file_format=Barracuda is the default in MariaDB 10.2.
Do not set it, because the option will be removed in MariaDB 10.3.
Also, do not set innodb_file_per_table=1 because it is the default.
Note that MDEV-11828 should fix the test innodb.innodb-64k
already in 10.1.

Tests that had to restore this amended
Two tests assumed it to be Antelope, make sure these run on a freshly
started server
The problem occurred when indexes are added between the time that an
UNDO record is created and the time that the purge thread comes around
and deletes the old secondary index entries. The purge thread would
hit an assert when trying to build a secondary index entry for
searching. The problem was that the old value of those fields were not
in the UNDO record since they were not part of an index when the UPDATE
occured.
A test case was added to innodb-index.test.
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
to begin with. Refuse to erase empty pages.
trx_undo_report_row_operation(): If the page for which the undo log
was too big was empty, free the undo page and return DB_TOO_BIG_RECORD.

Bug#12637786 was fixed with rb:692 by marko. But that fix has a remaining
bug. It added this assert;
ut_ad(ind_field->prefix_len);
before a section of code that assumes there is a prefix_len.
The patch replaced code that explicitly avoided this with a check for
prefix_len. It turns out that the purge thread can get to that assert
without a prefix_len because it does not use a row_ext_t* .
When UNIV_DEBUG is not defined, the affect of this is that the purge thread
sets the dfield->len to zero and then cannot find the entry in the index to
purge. So secondary index entries remain unpurged.
This patch does not do the assert. Instead, it uses
'if (ind_field->prefix_len) {...}'
around the section of code that assumes a prefix_len. This is the way the
patch I provided to Marko did it.
The test case is simply modified to do a sleep(10) in order to give the
purge thread a chance to run. Without the code change to row0row.c, this
modified testcase will assert if InnoDB was compiled with UNIV_DEBUG.
I tried to sleep(5), but it did not always assert.
With this change, the index prefix column length lifted from 767 bytes
to 3072 bytes if "innodb_large_prefix" is set to "true".

Fix a failure of the re-enabled innodb-index.test in the embedded server.
Apparently, the embedded server does not default to ENGINE=InnoDB when
copying an InnoDB table by CREATE TABLE t2 SELECT * FROM t1;
Re-enable a test that was disabled as collateral damage.
Starting with MySQL 5.5, queries will acquire and hold a shared meta-data lock
(MDL) on tables they process, until the transaction is committed or
rolled back. This will prevent DDL operations on the tables, such as creating
an index.
innodb-index.test: Use a second table for creating the index. The index will
still be "too new" for the transaction that was started before the index
creation was started.
