FMT_STATIC_THOUSANDS_SEPARATOR stopped working in 10.0.0
Let's not use this fmt version for now

even if pkg-config has it. otherwise build dependencies
aren't detected.

After MDEV-32551, in a master/slave setup, if the replica's IO thread
quickly and successively reconnects (i.e quickly running
STOP SLAVE IO_THREAD followed by START SLAVE IO_THREAD), the relay log
rotation behavior changes. That is, MDEV-32551 changed the logic of the
binlog_dump_thread on the primary, such that it can stop itself before
sending any events if it sees a new connection has been created to a
replica with the same server_id. Pre MDEV-32551, the connection would
establish and it would send a "fake" rotate event to populate the
log name. Post MDEV-32551, the connection stops itself, and a rotate
event is not sent.

This made the test rpl.rpl_mariadb_slave_capability unstable because
it is reliant on the name of the relay logs (which is dependent on the
number of rotates); and the pre-amble of the test would quickly
start/stop the IO thread. There a binlog dump thread could end itself
before sending a rotate event to the replica, thereby changing the name
of the relay log.

This patch fixes this by adding in a synchronization in-between IO thread
restarts, such that it waits for the primary's binlog dump threads to
sync up with the state of the replica.

test disabled, until fixed

rpl.rpl_seconds_behind_master_spike uses the DEBUG_SYNC mechanism to
count how many format descriptor events (FDEs) have been executed,
to attempt to pause on a specific relay log FDE after executing
transactions. However, depending on when the IO thread is stopped,
it can send an extra FDE before sending the transactions, forcing
the test to pause before executing any transactions, resulting in a
table not existing, that is attempted to be read for COUNT.

This patch fixes this by no longer counting FDEs, but rather by
programmatically waiting until the SQL thread has executed the
transaction and then automatically activating the DEBUG_SYNC point
to trigger at the next relay log FDE.

32bit uses less memory so the test for max_memory_usage does not work

This caused some crashes on 32 bit platforms.

A debug_sync signal could remain for the SQL thread that should have begun
a wait_for upon seeing a GTID event, but would instead see the old signal
and continue on without waiting. This broke an "idle" condition in
SHOW SLAVE STATUS
which should have automatically negated Seconds_Behind_Master. Instead,
because the SQL thread had already processed the GTID event, it set
sql_thread_caught_up to false, and thereby calculated the value of
Seconds_behind_master, when the test expected 0.

This patch fixes this by resetting the debug_sync state before creating a
new transaction which sends a GTID event to the replica

Let us suppress this timing-sensitive warning globally.
We added it in commit d34479dc (MDEV-33053)
so that in case InnoDB hangs due to running out of buffer pool, there
would be a warning about it. On a heavily loaded system that is running
with a small buffer pool, these warnings may be occasionally issued
while page writes are in progress.

With this patch, 4-component MSI version can be used, e.g by setting
TINY_VERSION variable in CMake, or by adding a string, e.g
MYSQL_VERSION_EXTRA=-2
which sets TINY_VERSION to 2, and also changes the package name.

The 4-component MSI versions do not support MSI major upgrades, only minor
ones, i.e do not reinstall components, just update existing ones based
on versioning rules.

To support these rules, add DefaultVersion for the files that won't
otherwise be versioned - headers, static and import libraries,
pdbs, text - xml, python and perl scripts Also silence WiX warning
that MSI won't store hashes for those files anymore.

Testing exit code from popen(), comparing it with 1, and deciding that
perl.exe is not there, is a) wrong conclusion, and b) uninteresting,
because MTR always runs with perl, and with MTR_PERL set.

Background:
Recent change in 7af50e4d introduced
exit code 1 from perl snippet, that broke Windows CI. Do not want
to debug this ever again.

There are two array fields in spider_share with similar names:

share->use_sql_dbton_ids that maps from i to the i-th dbton used by
share. Thus it should be used only when i iterates over all distinct
dbtons used by share.

share->sql_dbton_ids that maps from i to the dbton used by the i-th
link of the share. Thus it should be used only when i iterates over
all links of a share.

We correct instances where share->sql_dbton_ids should be used instead
of share->use_sql_dbton_ids.

write_record() when performing REPLACE has an optimization:
- if the unique violation happened in the last unique key, then do UPDATE
- otherwise, do DELETE+INSERT

This patch changes the way of detecting if this optimization
can be applied if the table has long (hash based) unique
(i.e. UNIQUE..USING HASH) constraints.

Problem:

The old condition did not take into account that
TABLE_SHARE and TABLE see long uniques differently:
- TABLE_SHARE sees as HA_KEY_ALG_LONG_HASH and HA_NOSAME
- TABLE sees as usual non-unique indexes
So the old condition could erroneously decide that the UPDATE optimization
is possible when there are still some unique hash constraints in the table.

Fix:

- If the current key is a long unique, it now works as follows:

  UPDATE can be done if the current long unique is the last
  long unique, and there are no in-engine (normal) uniques.

- For in-engine uniques nothing changes, it still works as before:

  If the current key is an in-engine (normal) unique:
  UPDATE can be done if it is the last normal unique.

Turning REGEXP_REPLACE into two schema-qualified functions:
- mariadb_schema.regexp_replace()
- oracle_schema.regexp_replace()

Fixing oracle_schema.regexp_replace(subj,pattern,replacement) to treat
NULL in "replacement" as an empty string.

Adding new classes implementing oracle_schema.regexp_replace():
- Item_func_regexp_replace_oracle
- Create_func_regexp_replace_oracle

Adding helper methods:
- String *Item::val_str_null_to_empty(String *to)
- String *Item::val_str_null_to_empty(String *to, bool null_to_empty)

and reusing these methods in both Item_func_replace and
Item_func_regexp_replace.

The IDENT_sys doesn't include keywords, so the function with the
keyword name can be created, but cannot be called.
Moving keywords to new rules keyword_func_sp_var_and_label and
keyword_func_sp_var_not_label so the functions with these
names are allowed.

When CMAKE_OSX_ARCHITECTURES isn't set we end up with
"Packaging as: mariadb-10.4.33-osx10.19-x86_64" on arm64 builders.

Instead of implying 64bit is x86, use CMAKE_SYSTEM_PROCESSOR to form
the filename.

More in depth check to cover all used readline functions.

use the original, not the truncated, field in the long unique prefix,
that is, in the hash(left(field, length)) expression.

because MyISAM CHECK/REPAIR in compute_vcols() moves table->field
but not prefix fields from keyparts.

Also, implement Field_string::cmp_prefix() for prefix comparison
of CHAR columns to work.

no need to use it when both arguments have the same length

use thd->start_time for the "start_time" column of the slow_log table.
"current_time" here refers to the current_time() function return value
not to the actual *current* time.

We can check only fields which take part in inserts.

Most things where wrong in the test suite.
The one thing that was a bug was that table_map_id was in some places
defined as ulong and in other places as ulonglong. On Linux 64 bit this
is not a problem as ulong == ulonglong, but on windows this caused failures.
Fixed by ensuring that all instances of table_map_id are ulonglong.
