Test crash recovery from an encrypted redo log with innodb_encrypt_log=0.
Previously, we did a clean shutdown, so only the log checkpoint
information would have been read from the redo log. With this change,
we will be reading and applying encrypted redo log records.
include/start_mysqld.inc: Observe $restart_parameters.
encryption.innodb-log-encrypt: Remove some unnecessary statements,
and instead of restarting the server and concurrently accessing
the files while the server is running, kill the server, check the
files, and finally start up the server.
innodb.log_data_file_size: Use start_mysqld.inc with $restart_parameters.

- MDEV-11621 rpl.rpl_gtid_stop_start fails sporadically in buildbot
- MDEV-11620 rpl.rpl_upgrade_master_info fails sporadically in buildbot
The issue above was probably that the build machine was overworked and the
shutdown took longer than 30 resp 10 seconds, which caused MyISAM tables
to be marked as crashed.
Fixed by flushing myisam tables before doing a forced shutdown/kill.
I also increased timeout for forced shutdown from 10 seconds to 60 seconds
to fix other possible issues on slow machines.
Fixed also some compiler warnings

encryption.innodb_scrub: Clean up. Make it also cover ROW_FORMAT=COMPRESSED,
removing the need for encryption.innodb_scrub_compressed.
Add a FIXME comment saying that we should create a secondary index, to
demonstrate that also undo log pages get scrubbed. Currently that is
not working!
Also clean up encryption.innodb_scrub_background, but keep it disabled,
because the background scrubbing does not work reliably.
Fix both tests so that if something is not scrubbed, the test will be
aborted, so that the data files will be preserved. Allow the tests to
run on Windows as well.

This should be functionally equivalent to WL#6204 in MySQL 8.0.0, with
the notable difference that the file format changes are limited to
repurposing a previously unused data field in B-tree pages.
For persistent InnoDB tables, write the last used AUTO_INCREMENT
value to the root page of the clustered index, in the previously
unused (0) PAGE_MAX_TRX_ID field, now aliased as PAGE_ROOT_AUTO_INC.
Unlike some other previously unused InnoDB data fields, this one was
actually always zero-initialized, at least since MySQL 3.23.49.
The writes to PAGE_ROOT_AUTO_INC are protected by SX or X latch on the
root page. The SX latch will allow concurrent read access to the root
page. (The field PAGE_ROOT_AUTO_INC will only be read on the
first-time call to ha_innobase::open() from the SQL layer. The
PAGE_ROOT_AUTO_INC can only be updated when executing SQL, so
read/write races are not possible.)
During INSERT, the PAGE_ROOT_AUTO_INC is updated by the low-level
function btr_cur_search_to_nth_level(), adding no extra page
access. [Adaptive hash index lookup will be disabled during INSERT.]
If some rare UPDATE modifies an AUTO_INCREMENT column, the
PAGE_ROOT_AUTO_INC will be adjusted in a separate mini-transaction in
ha_innobase::update_row().
When a page is reorganized, we have to preserve the PAGE_ROOT_AUTO_INC
field.
During ALTER TABLE, the initial AUTO_INCREMENT value will be copied
from the table. ALGORITHM=COPY and online log apply in LOCK=NONE will
update PAGE_ROOT_AUTO_INC in real time.
innodb_col_no(): Determine the dict_table_t::cols[] element index
corresponding to a Field of a non-virtual column.
(The MySQL 5.7 implementation of virtual columns breaks the 1:1
relationship between Field::field_index and dict_table_t::cols[].
Virtual columns are omitted from dict_table_t::cols[]. Therefore,
we must translate the field_index of AUTO_INCREMENT columns into
an index of dict_table_t::cols[].)
Upgrade from old data files:
By default, the AUTO_INCREMENT sequence in old data files would appear
to be reset, because PAGE_MAX_TRX_ID or PAGE_ROOT_AUTO_INC would contain
the value 0 in each clustered index page. In new data files,
PAGE_ROOT_AUTO_INC can only be 0 if the table is empty or does not contain
any AUTO_INCREMENT column.
For backward compatibility, we use the old method of
SELECT MAX(auto_increment_column) for initializing the sequence.
btr_read_autoinc(): Read the AUTO_INCREMENT sequence from a new-format
data file.
btr_read_autoinc_with_fallback(): A variant of btr_read_autoinc()
that will resort to reading MAX(auto_increment_column) for data files
that did not use AUTO_INCREMENT yet. It was manually tested that during
the execution of innodb.autoinc_persist the compatibility logic is
not activated (for new files, PAGE_ROOT_AUTO_INC is never 0 in nonempty
clustered index root pages).
initialize_auto_increment(): Replaces
ha_innobase::innobase_initialize_autoinc(). This initializes
the AUTO_INCREMENT metadata. Only called from ha_innobase::open().
ha_innobase::info_low(): Do not try to lazily initialize
dict_table_t::autoinc. It must already have been initialized by
ha_innobase::open() or ha_innobase::create().
Note: The adjustments to class ha_innopart were not tested, because
the source code (native InnoDB partitioning) is not being compiled.

* some of these tests run just fine with InnoDB:

* sys_var tests did basic tests for xtradb only variables
-> remove them, they're useless anyway (sysvar_innodb does it better)

Item_func_conv_charset::fix_length_and_dec()
MDEV-10850 Wrong result for WHERE .. (f2=TO_BASE64('test') OR f2=TO_BASE64('TEST'))
Problem N1: MDEV-10425
Item_func_{md5|sha|sha2}::fix_length_and_dec() changed args[0]->collation
to force binary comparison in args[0]->eq().
It was done to treat e.g. MD5('a') and MD5('A') as different values.
It is wrong for a Item_func_xxx to modify its arguments.
Item_func_conv_charset did not expect that and crashed on assert.
Problem N2: MDEV-10850
Item_func_to_base64, Item_func_password, Item_func_hex are also case sensitive
hash functions, but they did not compare their arguments as binary.
Solution:
- Removing the code changing args[0]->collation
- Introducing Item_str_ascii_checksum_func as a common parent
for Item_func_{md5|sha|sha2|password|hex|to_base64}
and overriding its eq() method to compare arguments binary.

- find a prelocked table by name
- open a table (from a background purge thread)
* different from 5.7:

destroyed at the correct point in time during the server shutdown
- proper opening/closing of tables for vcol evaluations in
+ FK checks (use already opened prelocked tables)
+ purge threads (open the table, MDLock it, add it to tdc, close
when not needed)
- cache open tables in vc_templ
- avoid unnecessary allocations, reuse table->record[0] and table->s->default_values
- not needed in 5.7, because it overcalculates:
+ tell the server to calculate vcols for an on-going inline ADD INDEX
+ calculate vcols for correct error messages
* update other engines (mroonga/tokudb) accordingly

cannot use TABLE:merge_keys for that, because Field::part_of_key
was designed to mark fields for KEY_READ, so a field is not a
"part of key", if only prefix of the field is.

for InnoDB tables"
Don't use thr_lock.c locks for InnoDB tables. Below is list of changes that
were needed to implement this:
- HANDLER OPEN acquireis MDL_SHARED_READ instead of MDL_SHARED
- HANDLER READ calls external_lock() even if SE is not going to be locked by
THR_LOCK
- InnoDB lock wait timeouts are now honored which are much shorter by default
than server lock wait timeouts (1 year vs 50 seconds)
- with @@autocommit= 1 LOCK TABLES disables autocommit implicitely, though
user still sees @@autocommt= 1
- the above starts implicit transaction
- transactions started by LOCK TABLES are now rolled back on disconnect
(previously everything was committed due to autocommit)
- transactions started by LOCK TABLES are now rolled back by ROLLBACK
(previously everything was committed due to autocommit)
- it is now impossible to change BINLOG_FORMAT under LOCK TABLES (at least
to statement) due to running transaction
- LOCK TABLES WRITE is additionally handled by MDL
- ...in contrast LOCK TABLES READ protection against DML is pure InnoDB
- combining transactional and non-transactional tables under LOCK TABLES
may cause rolled back changes in transactional table and "committed"
changes in non-transactional table
- user may disable innodb_table_locks, which will cause LOCK TABLES to be
noop basically
Removed tests for BUG#45143 and BUG#55930 which cover InnoDB + THR_LOCK. To
operate properly these tests require code flow to go through THR_LOCK debug
sync points, which is not the case after this patch. These tests are removed
by WL#6671 as well. An alternative is to port them to different storage engine.

Merge feature into 10.2 from feature branch.
Delayed replication adds an option
CHANGE MASTER TO master_delay=<seconds>
Replication will then delay applying events with that many
seconds. This creates a replication slave that reflects the state of
the master some time in the past.
Feature is ported from MySQL source tree.

Problem:
When using the delayed slave feature, and the SQL thread is delaying,
and the user issues STOP SLAVE, the event we wait for was executed.
It should not be executed.
Fix:
Check the return value from the delay function,
slave.cc:slave_sleep(). If the return value is 1, it means the thread
has been stopped, in this case we don't execute the statement.
Also, refactored the test case for delayed slave a little: added the
test script include/rpl_assert.inc, which asserts that a condition holds
and prints a message if not. Made rpl_delayed_slave.test use this. The
advantage is that the test file is much easier to read and maintain,
because it is clear what is an assertion and what is not, and also the
expected result can be found in the test file, you don't have to compare
it to the result file.

Initial merge of delayed replication from MySQL git.
The code from the initial push into MySQL is merged, and the
associated test case passes. A number of tasks are still pending:
1. Check full test suite run for any regressions or .result file updates.
2. Extend the feature to also work for parallel replication.
3. There are some todo-comments about future refactoring left from
MySQL, these should be located and merged on top.
4. There are some later related MySQL commits, these should be checked
and merged. These include:
e134b9362ba0b750d6ac1b444780019622d14aa5
b38f0f7857c073edfcc0a64675b7f7ede04be00f

afc397376ec50e96b2918ee64e48baf4dda0d37d
5. The testcase from MySQL relies heavily on sleep and timing for
testing, and seems likely to sporadically fail on heavily loaded test
servers in buildbot or distro build farms.

This is similar to MysQL Worklog 3253, but with
a different implementation. The disk format and
SQL syntax is identical with MySQL 5.7.
Fetures supported:
- "Any" ammount of any trigger
- Supports FOLLOWS and PRECEDES to be
able to put triggers in a certain execution order.
Implementation details:
- Class Trigger added to hold information about a trigger.
Before this trigger information was stored in a set of lists in
Table_triggers_list and in Table_triggers_list::bodies
- Each Trigger has a next field that poinst to the next Trigger with the
same action and time.
- When accessing a trigger, we now always access all linked triggers
- The list are now only used to load and save trigger files.
- MySQL trigger test case (trigger_wl3253) added and we execute these
identically.
- Even more gracefully handling of wrong trigger files than before. This
is useful if a trigger file uses functions or syntax not provided by
the server.
- Each trigger now has a "Created" field that shows when the trigger was
created, with 2 decimals.
Other comments:
- Many of the changes in test files was done because of the new "Created"
field in the trigger file. This shows up in SHOW ... TRIGGER and when
using information_schema.trigger.
- Don't check if all memory is released if on uses --gdb; This is needed
to be able to get a list from safemalloc of not freed memory while
debugging.
- Added option to trim_whitespace() to know how many prefix characters
was skipped.
- Changed a few ulonglong sql_mode to sql_mode_t, to find some wrong usage
of sql_mode.

compiled for debugging, when the server goes down
This happens in the following scenario:
- Server gets a shutdown message
- Servers sends error ER_CONNECTION_KILLED to the clients connection
- The client sends a query to the server, before the server has time to
close the connection to the client
- Client reads the ER_CONNECTION_KILLED error message
In the above case, the packet number for the reply is one less than
what the client expected and the client prints "Packets out of order".
Fixed the following way:
- The client accepts now error packages with a packet number
one less than expected.
- To ensure that this issue can be detected early in my_real_read(), error
messages sent to the client are not compressed, even when compressed protocol is used.
