On Microsoft Windows, InnoDB writes the path separator \ to the
redo log file, while on all other platforms, / is being used.
fil_name_parse(): Normalize the parsed path separators to the
native format. This allows backups or data sets to be portable
between Windows and other systems.

IGNORE .. FOR PORTION with binary logging
The fix is same as for MDEV-18859: initialize table->rpl_write_set in
FOR PORTION OF case.

THD::binlog_write_row upon DELETE .. FOR PORTION with binary logging
rpl_write_set is initialized in TABLE::mark_columns_per_binlog_row_image.
Since we just call use_all_columns for PORTION OF case, no need in
column marking logic here. Instead, initialize table->rpl_write_set in
place.

with ``--ps-protocol`
The main problem was lack of proper QueryArena handling in
`period_setup_conds`. Since mysql_prepare_update/mysql_prepare_delete
are called during `PREPARE` statement, period conditions, should be
allocated on statement query arena.
Another problem is incorrect statement state handling in
period_setup_conds, which led to unexpected mysql_update termination.
* mysql_update: move period_setup_conds() to mysql_prepare_update to
store conditions in statement's mem_root
* mtr: add period suite to default list, since --ps-protocol is now
fixed
Fixes bugs:
MDEV-18853 Assertion `0' failed in Protocol::end_statement upon DELETE .. FOR PORTION via prepared statement
MDEV-18852 Server crashes in reinit_stmt_before_use upon UPDATE .. FOR PORTION via prepared statement

InnoDB includes 3 parsers, which use 3 lexical analyzers that
are generated with flex. Flex versions before 2.6 emitted
the keyword "register", which is deprecated in C++17.
The lexical analyzers were regenerated as follows:
for s in storage/innobase storage/xtradb
do
(cd "$s"/pars; ./make_flex.sh)
touch "$s"/fts/*.l
make -C "$s"/fts -f Makefile.query
done

INFORMATION_SCHEMA.INNODB_TABLESPACES_SCRUBBING.ROTATING_OR_FLUSHING
The MDEV-11738/MDEV-11581 fix was supposed to add the column
ROTATING_OR_FLUSHING to the INFORMATION_SCHEMA table
INNODB_TABLESPACES_ENCRYPTION, but it also added that column to
INNODB_TABLESPACES_SCRUBBING in InnoDB (not XtraDB).
The extra column was never initialized. We will remove it,
because key rotation has nothing to do with the scrubbing of
tablespace data.

MariaDB before MDEV-5800 in version 10.2.2 did not support
indexed virtual columns. Non-persistent virtual columns were
hidden from storage engines. Only starting with MDEV-5800, InnoDB
would create internal metadata on virtual columns.
Similar to what was done in MDEV-18084, MDEV-18090, MDEV-18960, we adjust
one more code path for the old tables.
innobase_build_col_map(): Allocate space for virtual columns in col_map[]
but leave the entries at ULINT_UNDEFINED, noting that the virtual columns
were missing before the table was being rebuilt.

This reverts commit 21b2fada7ab7f35c898c02d2f918461409cc9c8e
and commit 81d71ee6b21870772c336bff15b71904914f146a.
The MDEV-18464 change introduces a few data race issues. Contrary to
the documentation, the field trx_t::victim is not always being protected
by lock_sys_t::mutex and trx_t::mutex. Most importantly, it seems
that KILL QUERY could wrongly avoid acquiring both mutexes when
invoking lock_trx_handle_wait_low(), in case another thread had
already set trx->victim=true.
We also revert MDEV-12009, because it should depend on the MDEV-18464
fix being present.

priority by Galera
As noted on kill_one_thread SUPER should be able to kill even
system threads i.e. threads/query flagged as high priority or
wsrep applier thread. Normal user, should not able to kill
threads/query flagged as high priority (BF) or wsrep applier
thread.

Pushed the decision for innodb transaction and system
locking down to lock0lock.cc level. With this,
we can avoid releasing these mutexes for executions
where these mutexes were acquired upfront.
This patch will also fix BF aborting of native threads, e.g.
threads which have declared wsrep_on=OFF. Earlier, we have
used, for innodb trx locks, was_chosen_as_deadlock_victim
flag, for marking inodb transactions, which are victims for
wsrep BF abort. With native threads (wsrep_on==OFF), re-using
was_chosen_as_deadlock_victim flag may lead to inteference
with real deadlock, and to deal with this, the patch has added new
flag for marking wsrep BF aborts only: victim=true
Similar way if replication decides to abort one of the threads
we mark victim by: victim=true
innobase_kill_query
Remove lock sys and trx mutex handling.
wsrep_innobase_kill_one_trx
Mark victim trx with victim=true
trx0trx.h
Remove trx_abort_t type and abort type variable from
trx struct. Add victim variable to trx.
wsrep_kill_victim
Remove abort_type
lock_report_waiters_to_mysql
Take also trx mutex and mark trx as a victim for
replication abort.
lock_trx_handle_wait_low
New low level function to check whether the transaction
has already been rolled back because it was selected as
a deadlock victim, or if it has to wait then cancel
the wait lock.
lock_trx_handle_wait
If transaction is not marked as victim take lock sys
and trx mutex before calling lock_trx_handle_wait_low
and release them after that.
row_search_for_mysql
Remove lock sys and trx mutex taking and releasing.
trx_rollback_to_savepoint_for_mysql_low
trx_commit_in_memory
Clean up victim variable.

special cases:
* change systemd detection to use CHECK_LIBRARY_EXISTS at least once,
to have it detected by build_depends.cmake
* similarly, use find_library for pam
* unixODBC is weird, libodbc.so is in the unixODBC package, not
in the unixODBC-devel, where normally all .so files belong.
Packaging bug? As a workaround, use find_file(sql.h) instead of
find_path(sql.h) to make sure that /usr/include/sql.h (not /usr/include)
is cached by cmake, and later build_depends.cmake will select
unixODBC-devel, as a package owning /usr/include/sql.h file.

automatic BuildRequires for source RPM: for every FILEPATH and
"Have library XXX" cached variable, detect what rpm package it comes from
and add it to the list of dependencies.
That is, the source RPM will BuildRequire all those packages that
were found by cmake when the source RPM was built. Presumably, our
CMakeLists.txt won't check for libraries that aren't needed for a build.
It supports libraries/executables/files found with
FIND_LIBRARY

Only do it for a reasonably new cmake, where
source rpms are known to work (3.10.2 is ok, 3.5.2 is not).

Problem:
========
When applier thread tries to access 'variable_name' of
INFORMATION_SCHEMA.SESSION_VARIABLES table through triggers, it results in an
abnormal exit of slave server.
Analysis:
========
At the time of replication of stored routines and triggers, their associated
security context will be sent by the master. The applier thread on the slave
server will use this information to set the required security context for the
execution of stored routines and triggers. This is achieved as follows.
->The stored routine object has a member named 'm_security_ctx' which holds the
security context received from master.
->The applier thread's security_ctx is stored into a 'backup' object.
->Set the applier thread's security_ctx to 'm_security_ctx'.
->Upon the completion of stored routine execution restore the original security
context of applier thread from the backup.
During the above process the 'm_security_ctx' object is not initialized
properly. Hence the 'external_user' of 'm_security_ctx' has invalid value for
this variable and accessing this variable results in abnormal exit of server.
Fix:
===
Invoke the Security_context::init() call from the constructor of stored routine
so that 'm_security_ctx' gets initialized properly.

When HAVE_YASSL is defined (due to cmake -DWITH_SSL=bundled
or otherwise), mysys_ssl/my_crypt.cc will #include "yassl.cc"
from the same directory.
When MariaDB 10.2 or later is compiled with GCC 8 and optimizations
are enabled, then the check
if (iv)
in EVP_CipherInit_ex() can be wrongly optimized away.
The reason appears to be that __attribute__((nonnull)) is attached
to the variable iv, because there is a (no-op) call
memcpy(oiv, iv, ivlen=0) earlier in the code path.
It is possible that this started failing after the code was
refactored in MDEV-10332 (MariaDB 10.2.6). In MariaDB 10.1,
there is a similar memcpy() call in MyCTX_nopad::init(),
but the code appears to work fine.

Problem:
========
When attempting to delay a Slave attached with GTID, there appears to be an
extra delay applied initially. For example, this output reflects a Slave that is
already delayed by 43200 seconds. When switching to GTID replication,
replication is paused until SQL_Remaining_Delay counts down to 0:
CHANGE MASTER TO master_use_gtid=current_pos; CHANGE MASTER TO
MASTER_DELAY=43200;
Seconds_Behind_Master: 44847
Using_Gtid: Current_Pos
SQL_Delay: 43200
SQL_Remaining_Delay: 43089
Slave_SQL_Running_State: Waiting until MASTER_DELAY seconds after master
executed event
Analysis:
=========
When slave initiates a GTID based connection request to master, the master sends
two GTID_LIST events. The first one is actual GTID_LIST event and the second
one is a fake GTID_LIST event. This is sent by master to provide its current
binlary log file position. The fake GTID_LIST events will have their ev->when=0.
'when' (the timestamp) is set to 0 so that slave could distinguish between real
and fake Rotate events.
On slave side when MASTER_DELAY is configured to "X" the applier will ensure
that there is a time delay of "X" seconds before the event is applied.
General behaviour of MASTER_DELAY example:-
Master
timestamp of event e1=10
timestamp of event e2=11
On slave MASTER_DELAY=5
Event e1 will be applied at = 15
e2 will be applied at =16
In bug scenario:-
On Master: With GTIDs
timestamp of event e1=10
timestamp of event e2=0
On Slave:
e1 will be applied at = 10 + 5 =15
For e2, since "e2->when=0" e2->when is set to current timestamp.
i.e since the e2->when and current timestamp on slave is the same applier waits
for additional master_delay=5 seconds. the ev->when contributes to
"rli->last_master_timestamp".
rli->last_master_timestamp= ev->when + (time_t) ev->exec_time;
Fake events should not update the "ev->when" to "current timestamp" on slave.
Fix:
===
Remove the assignment of current timestamp to "ev->when" when "ev->when=0".
