Analysis:
=========
During alter table rebuild, InnoDB fails to apply concurrent insert log.
If the insert log record is present across the blocks then apply phase
trying to access the next block without fetching it.
Fix:
====
During virtual column parsing, check whether the record is present
across the blocks before accessing the virtual column information.

========
During alter table rebuild, InnoDB fails to apply concurrent delete log.
Parsing and validation of merge record happens while applying the
log operation on a table. Validation goes wrong for the virtual column.
Validation assumes that virtual column information can't be the end
of the merge record end.
Fix:
====
Virtual column information in the merge record can be end of the merge
record. Virtual column information is written at the end for
row_log_table_delete().

MariaDB 10.2 never contained the Oracle change
Bug#23481444 OPTIMISER CALL ROW_SEARCH_MVCC() AND READ THE
INDEX APPLIED BY UNCOMMITTED ROWS
because it was considered risky for a GA release and incomplete.
Remove the references that were added when merging MySQL 5.6.36
to MariaDB 10.0.31, 10.1.24, and 10.2.7.
Analysis:
========
(1) During TRUNCATE of file_per_table tablespace, dict_operation_lock is
released before eviction of dirty pages of a tablespace from the buffer
pool. After eviction, we try to re-acquire
dict_operation_lock (higher level latch) but we already hold lower
level latch (index->lock). This causes latch order violation
(2) Deadlock issue is present if child table is being truncated and it
holds index lock. At the same time, cascade dml happens and it took
dict_operation_lock and waiting for index lock.
Fix:
====
1) Release the indexes lock before releasing the dict operation lock.
2) Ignore the cascading dml operation on the parent table, for the
cascading foreign key, if the child table is truncated or if it is
in the process of being truncated.

Bug #25189192 ERRORS WHEN RESTARTING MYSQL AFTER RENAME TABLE.
PROBLEM
While renaming table innodb doesn't update the InnoDB Dictionary table
INNODB_SYS_DATAFILES incase there is change in database while doing
rename table. Hence on a restart the server log shows error that it
couldnt find table with old path before rename which has actually been
renamed. So the errors would only vanish if we update the system
tablespace
FIX
Update the innodb dictionary table with new path in the case there is
not a change in the table but the database holding the table as well.

The POINT data type is being treated just like any other
geometry data type in InnoDB. The fixed-length data type
DATA_POINT had been introduced in WL#6942 based on a
misunderstanding and without appropriate review.
Because of fundamental design problems (such as a
DEFAULT POINT(0 0) value secretly introduced by InnoDB),
the code was disabled in Oracle Bug#20415831 fix.
This patch removes the dead code and definitions that were
left behind by the Oracle Bug#20415831 patch.
This is preparation for MDEV-12288, which would set DB_TRX_ID=0
when purging history. Also with that change in place, delete-marked
records must always refer to an undo log record via a nonzero
DB_TRX_ID column. (The DB_TRX_ID is only present in clustered index
leaf page records.)
btr_cur_parse_del_mark_set_clust_rec(), rec_get_trx_id():
Statically allocate the offsets
(should never use the heap). Add some debug assertions.
Replace some use of rec_get_trx_id() with row_get_rec_trx_id().
trx_undo_report_row_operation(): Add some sanity checks that are
common for all operations that produce undo log.
The field fts_token->position is not initialized in
row_merge_fts_doc_tokenize(). We cannot have that field
without changing the fulltext parser plugin ABI
(adding st_mysql_ftparser_boolean_info::position,
as it was done in MySQL 5.7 in WL#6943).
The InnoDB fulltext parser plugins "ngram" and "Mecab" that were
introduced in MySQL 5.7 do depend on that field. But the simple_parser
does not. Apparently, simple_parser is leaving the field as 0.
So, in our fix we will assume that the missing position field is 0.
While the primary purpose of innodb_force_recovery is to allow
data to be rescued from an InnoDB instance that would crash due
to some data corruption, the settings 1, 2, or 3 are relatively
safe to use and there is no need to prevent write transactions
in these modes.
The setting innodb_force_recovery=4 and above can cause database
corruption. For those modes, we already set the flag
high_level_read_only to disable modifications, except DROP TABLE.
MODIFICATIONS_NOT_ALLOWED_MSG_FORCE_RECOVERY: Remove. There is no
need to spam the error log for each refused DML operation. It suffices
to return an error to the client. There will be messages at startup
if innodb_read_only or innodb_force_recovery are preventing writes.
Comment from Codership:-
To fix the problem, we changed the certification logic in galera to treat insert
on child table row as exclusive to prevent any operation on referenced
parent table row. At the same time, update and delete on
child table row were demoted to "shared", which makes it possible to
update/delete referenced parent table row, but only in a later transaction.
This change allows somewhat more concurrency for foreign key constrained
transactions, but is still safe for correct certification end result.
When the btr_search_latch was split into an array of latches
in MySQL 5.7.8 as part of the Oracle Bug#20985298 fix, the "caching"
of the latch across storage engine API calls was removed, and
the field trx->has_search_latch would only be set during a short
time frame in the execution of row_search_mvcc(), which was
formerly called row_search_for_mysql().
This means that the column
INFORMATION_SCHEMA.INNODB_TRX.TRX_ADAPTIVE_HASH_LATCHED will always
report 0. That column cannot be removed in MariaDB 10.2, but it
can be removed in future releases.
trx_t::has_search_latch: Remove.
trx_assert_no_search_latch(): Remove.
row_sel_try_search_shortcut_for_mysql(): Remove a redundant condition
on trx->has_search_latch (it was always true).
sync_check_iterate(): Make the parameter const.
sync_check_functor_t: Make the operator() const, and remove result()
and the virtual destructor. There is no need to have mutable state
in the functors.
sync_checker<bool>: Replaces dict_sync_check and btrsea_sync_check.
sync_check: Replaces btrsea_sync_check.
dict_sync_check: Instantiated from sync_checker.
sync_allowed_latches: Use std::find() directly on the array.
Remove the std::vector.
TrxInInnoDB::enter(), TrxInInnoDB::exit(): Remove obviously redundant
debug assertions on trx->in_depth, and use equality comparison against 0
because it could be more efficient on some architectures.
innodb.table_flags: Adjust the test case. Due to the MDEV-12873 fix
in 10.2, the corrupted flags for table test.td would be converted,
and a tablespace flag mismatch will occur when trying to open the file.
Remove the SHARED_SPACE flag that was erroneously introduced in
MariaDB 10.2.2, and shift the SYS_TABLES.TYPE flags back to where
they were before MariaDB 10.2.2. While doing this, ensure that
tables created with affected MariaDB versions can be loaded,
and also ensure that tables created with MySQL 5.7 using the
TABLESPACE attribute cannot be loaded.
MariaDB 10.2.2 picked the SHARED_SPACE flag from MySQL 5.7,
shifting the MariaDB 10.1 flags PAGE_COMPRESSION, PAGE_COMPRESSION_LEVEL,
ATOMIC_WRITES by one bit. The SHARED_SPACE flag would always
be written as 0 by MariaDB, because MariaDB does not support
CREATE TABLESPACE or CREATE TABLE...TABLESPACE for InnoDB.
So, instead of the bits AALLLLCxxxxxxx we would have
AALLLLC0xxxxxxx if the table was created with MariaDB 10.2.2
to 10.2.6. (AA=ATOMIC_WRITES, LLLL=PAGE_COMPRESSION_LEVEL,
C=PAGE_COMPRESSED, xxxxxxx=7 bits that were not moved.)
PAGE_COMPRESSED=NO implies LLLLC=00000. That is not a problem.
If someone created a table in MariaDB 10.2.2 or 10.2.3 with
the attribute ATOMIC_WRITES=OFF (value 2; AA=10) and without
PAGE_COMPRESSED=YES or PAGE_COMPRESSION_LEVEL, the table should be
rejected. We ignore this problem, because it should be unlikely
for anyone to specify ATOMIC_WRITES=OFF, and because 10.2.2 and
10.2.2 were not mature releases. The value ATOMIC_WRITES=ON (1)
would be interpreted as ATOMIC_WRITES=OFF, but starting with
MariaDB 10.2.4 the ATOMIC_WRITES attribute is ignored.
PAGE_COMPRESSED=YES implies that PAGE_COMPRESSION_LEVEL be between
1 and 9 and that ROW_FORMAT be COMPACT or DYNAMIC. Thus, the affected
wrong bit pattern in SYS_TABLES.TYPE is of the form AALLLL10DB00001
where D signals the presence of a DATA DIRECTORY attribute and B is 1
for ROW_FORMAT=DYNAMIC and 0 for ROW_FORMAT=COMPACT. We must interpret
this bit pattern as AALLLL1DB00001 (discarding the extraneous 0 bit).
dict_sys_tables_rec_read(): Adjust the affected bit pattern when
reading the SYS_TABLES.TYPE column. In case of invalid flags,
report both SYS_TABLES.TYPE (after possible adjustment) and
SYS_TABLES.MIX_LEN.
dict_load_table_one(): Replace an unreachable condition on
!dict_tf2_is_valid() with a debug assertion. The flags will already
have been validated by dict_sys_tables_rec_read(); if that validation
fails, dict_load_table_low() will have failed.
fil_ibd_create(): Shorten an error message about a file pre-existing.
Datafile::validate_to_dd(): Clarify an error message about tablespace
flags mismatch.
ha_innobase::open(): Remove an unnecessary warning message.
dict_tf_is_valid(): Simplify and stricten the logic. Validate the
values of PAGE_COMPRESSION. Remove error log output; let the callers
handle that.
DICT_TF_BITS: Remove ATOMIC_WRITES, PAGE_ENCRYPTION, PAGE_ENCRYPTION_KEY.
The ATOMIC_WRITES is ignored once the SYS_TABLES.TYPE has been validated;
there is no need to store it in dict_table_t::flags. The PAGE_ENCRYPTION
and PAGE_ENCRYPTION_KEY are unused since MariaDB 10.1.4 (the GA release
was 10.1.8).
DICT_TF_BIT_MASK: Remove (unused).
FSP_FLAGS_MEM_ATOMIC_WRITES: Remove (the flags are never read).
row_import_read_v1(): Display an error if dict_tf_is_valid() fails.
dict_table_t::thd: Remove. This was only used by btr_root_block_get()
for reporting decryption failures, and it was only assigned by
ha_innobase::open(), and never cleared. This could mean that if a
connection is closed, the pointer would become stale, and the server
could crash while trying to report the error. It could also mean
that an error is being reported to the wrong client. It is better
to use current_thd in this case, even though it could mean that if
the code is invoked from an InnoDB background operation, there would
be no connection to which to send the error message.
Remove dict_table_t::crypt_data and dict_table_t::page_0_read.
These fields were never read.
fil_open_single_table_tablespace(): Remove the parameter "table".
The doublewrite buffer pages must fit in the first InnoDB system
tablespace data file. The checks that were added in the initial patch
(commit 112b21da37)
were at too high level and did not cover all cases.
innodb.log_data_file_size: Test all innodb_page_size combinations.
fsp_header_init(): Never return an error. Move the change buffer creation
to the only caller that needs to do it.
btr_create(): Clean up the logic. Remove the error log messages.
buf_dblwr_create(): Try to return an error on non-fatal failure.
Check that the first data file is big enough for creating the
doublewrite buffers.
buf_dblwr_process(): Check if the doublewrite buffer is available.
Display the message only if it is available.
recv_recovery_from_checkpoint_start_func(): Remove a redundant message
about FIL_PAGE_FILE_FLUSH_LSN mismatch when crash recovery has already
been initiated.
fil_report_invalid_page_access(): Simplify the message.
fseg_create_general(): Do not emit messages to the error log.
innobase_init(): Revert the changes.
trx_rseg_create(): Refactor (no functional change).
Problem was that all doublewrite buffer pages must fit to first
system datafile.

When MySQL 5.7 introduced fulltext parser plugins to InnoDB,

range for Boolean, we remove this code that was not intended to
be used in MariaDB 10.2.
fts_check_token(): Remove the special logic for N-gram tokens.
row_merge_write(): Pass the correct (possibly encrypted) buffer
to os_file_write_int_fd().
This bug was introduced in commit 65e1399e64
which included a commit to merge changes from MySQL 5.6.36 to
MariaDB Server 10.0.
Before MDEV-6812, it did not matter that merge_files[].offset was
uninitialized when no files were created.
This problem was introduced in MDEV-6812. There could be a user-visible
impact that the progress reports spit into the error log are bogus.

In my merge of the MySQL fix for Oracle Bug#23333990 / WL#9513
I overlooked some subsequent revisions to the test, and I also
failed to notice that the test is actually always failing.
Oracle introduced the parameter innodb_stats_include_delete_marked
but failed to consistently take it into account in FOREIGN KEY
constraints that involve CASCADE or SET NULL.
When innodb_stats_include_delete_marked=ON, obviously the purge of
delete-marked records should update the statistics as well.
One more omission was that statistics were never updated on ROLLBACK.
We are fixing that as well, properly taking into account the
parameter innodb_stats_include_delete_marked.
dict_stats_analyze_index_level(): Simplify an expression.
(Using the ternary operator with a constant operand is unnecessary
obfuscation.)
page_scan_method_t: Revert the change done by Oracle. Instead,
examine srv_stats_include_delete_marked directly where it is needed.
dict_stats_update_if_needed(): Renamed from
row_update_statistics_if_needed().
row_update_for_mysql_using_upd_graph(): Assert that the table statistics
are initialized, as guaranteed by ha_innobase::open(). Update the
statistics in a consistent way, both for FOREIGN KEY triggers and
for the main table. If FOREIGN KEY constraints exist, do not dereference
a freed pointer, but cache the proper value of node->is_delete so that
it matches prebuilt->table.
row_purge_record_func(): Update statistics if
innodb_stats_include_delete_marked=ON.
row_undo_ins(): Update statistics (on ROLLBACK of a fresh INSERT).
This is independent of the parameter; the record is not delete-marked.
row_undo_mod(): Update statistics on the ROLLBACK of updating key columns,
or (if innodb_stats_include_delete_marked=OFF) updating delete-marks.
innodb.innodb_stats_persistent: Renamed and extended from
innodb.innodb_stats_del_mark. Reduced the unnecessarily large dataset
from 262,144 to 32 rows. Test both values of the configuration
parameter innodb_stats_include_delete_marked.
Test that purge is updating the statistics.
innodb_fts.innodb_fts_multiple_index: Adjust the result. The test
is performing a ROLLBACK of an INSERT, which now affects the statistics.
include/wait_all_purged.inc: Moved from innodb.innodb_truncate_debug
to its own file.
The parameter thr of the function btr_cur_optimistic_insert()
is not declared as nonnull, but GCC 7.1.0 with -O3 is wrongly
optimizing away the first part of the condition
UNIV_UNLIKELY(thr && thr_get_trx(thr)->fake_changes)
when the function is being called by row_merge_insert_index_tuples()
with thr==NULL.
The fake_changes is an XtraDB addition. This GCC bug only appears
to have an impact on XtraDB, not InnoDB.
We work around the problem by not attempting to dereference thr
when both BTR_NO_LOCKING_FLAG and BTR_NO_UNDO_LOG_FLAG are set
in the flags. Probably BTR_NO_LOCKING_FLAG alone should suffice.
btr_cur_optimistic_insert(), btr_cur_pessimistic_insert(),
btr_cur_pessimistic_update(): Correct comments that disagree with
usage and with nonnull attributes. No other parameter than thr can
actually be NULL.
row_ins_duplicate_error_in_clust(): Remove an unused parameter.
innobase_is_fake_change(): Unused function; remove.
ibuf_insert_low(), row_log_table_apply(), row_log_apply(),
row_undo_mod_clust_low():
Because we will be passing BTR_NO_LOCKING_FLAG | BTR_NO_UNDO_LOG_FLAG
in the flags, the trx->fake_changes flag will be treated as false,
which is the right thing to do at these low-level operations
(change buffer merge, ALTER TABLE…LOCK=NONE, or ROLLBACK).
This might be fixing actual XtraDB bugs.
Other callers that pass these two flags are also passing thr=NULL,
implying fake_changes=false. (Some callers in ROLLBACK are passing
BTR_NO_LOCKING_FLAG and a nonnull thr. In these callers, fake_changes
better be false, to avoid corruption.)

Bug #23481444 OPTIMISER CALL ROW_SEARCH_MVCC() AND READ THE

row_search_for_mysql() does whole table traversal for range query

Solution:

Convert the innodb last record of page to mysql format and compare
with end range if the traversal of row_search_mvcc() exceeds 100,
