One change is that if the port is not supplied or out of bound, the
old behaviour is to print 3306. The new behaviour is to not print
it (if not supplied) or the out of bound value.
Only `mysql` client program was using $MYSQL_HOST as the default host.
Add the same feature in most other client programs but using
$MARIADB_HOST instead.

MDEV-32188 make TIMESTAMP use whole 32-bit unsigned range
- Added --update-history option to mariadb-dump to change 2038
row_end timestamp to 2106.
- Updated ALTER TABLE ... to convert old row_end timestamps to
2106 timestamp for tables created before MariaDB 11.4.0.
- Fixed bug in CHECK TABLE where we wrongly suggested to USE REPAIR
TABLE when ALTER TABLE...FORCE is needed.
- mariadb-check printed table names that where used with REPAIR TABLE but
did not print table names used with ALTER TABLE or with name repair.
Fixed by always printing a table that is fixed if --silent is not
used.
- Added TABLE::vers_fix_old_timestamp() that will change max-timestamp
for versioned tables when replication from a pre-11.4.0 server.
A few test cases changed. This is caused by:
- CHECK TABLE now prints 'Please do ALTER TABLE... instead of
'Please do REPAIR TABLE' when there is a problem with the information
in the .frm file (for example a very old frm file).
- mariadb-check now prints repaired table names.
- mariadb-check also now prints nicer error message in case ALTER TABLE
is needed to repair a table.
Currently there are mechanism to mark a system variable as
deprecated, but they are only used to print warning messages
when a deprecated variable is set.
Leverage the existing mechanisms in order to make the
deprecation information available at the --help output of mysqld by:
* Moving the deprecation information (i.e `deprecation_substitute`
attribute) from the `sys_var` class into the `my_option` struct.
As every `sys_var` contains its own `my_option` struct, the access
to the deprecation information remains available to `sys_var`
objects. `my_getotp` functions, which works directly with
`my_option` structs, gain access to this information while building
the --help output.
* For plugin variables, leverages the `PLUGIN_VAR_DEPRECATED` flag
and set the `deprecation_substitute` attribute accordingly when
building the `my_option` objects.
* Change the `option_cmp` function to use the `deprecation_substitute`
attribute instead of the name when sorting the options. This way
deprecated options and the substitutes will be grouped together.

New option works just like --tab, wrt output (sql file for table definition
and tab-separated for data, same options, e.g --parallel)
Compared to --tab it allows --databases and --all-databases.
When --dir is used , it creates directory structure in the output directory,
pointed to by --dir. For every database to be dumped, there will be a
directory with database name.
All options that --tab supports, are also supported by --dir, in particular
--parallel
This patch also fixes:
MDEV-33050 Build-in schemas like oracle_schema are accent insensitive
MDEV-33084 LASTVAL(t1) and LASTVAL(T1) do not work well with lower-case-table-names=0
MDEV-33085 Tables T1 and t1 do not work well with ENGINE=CSV and lower-case-table-names=0
MDEV-33086 SHOW OPEN TABLES IN DB1 -- is case insensitive with lower-case-table-names=0
MDEV-33088 Cannot create triggers in the database `MYSQL`
MDEV-33103 LOCK TABLE t1 AS t2 -- alias is not case sensitive with lower-case-table-names=0
MDEV-33109 DROP DATABASE MYSQL -- does not drop SP with lower-case-table-names=0
MDEV-33110 HANDLER commands are case insensitive with lower-case-table-names=0

MDEV-33120 System log table names are case insensitive with lower-cast-table-names=0
- Removing the virtual function strnncoll() from MY_COLLATION_HANDLER
- Adding a wrapper function CHARSET_INFO::streq(), to compare
two strings for equality. For now it calls strnncoll() internally.
In the future it will turn into a virtual function.
- Adding new accent sensitive case insensitive collations:
- utf8mb4_general1400_as_ci
- utf8mb3_general1400_as_ci
They implement accent sensitive case insensitive comparison.
The weight of a character is equal to the code point of its
upper case variant. These collations use Unicode-14.0.0 casefolding data.
The result of
my_charset_utf8mb3_general1400_as_ci.strcoll()
is very close to the former
my_charset_utf8mb3_general_ci.strcasecmp()
There is only a difference in a couple dozen rare characters, because:
- the switch from "tolower" to "toupper" comparison, to make
utf8mb3_general1400_as_ci closer to utf8mb3_general_ci
- the switch from Unicode-3.0.0 to Unicode-14.0.0
This difference should be tolarable. See the list of affected
characters in the MDEV description.
Note, utf8mb4_general1400_as_ci correctly handles non-BMP characters!
Unlike utf8mb4_general_ci, it does not treat all BMP characters
as equal.
- Adding classes representing names of the file based database objects:
Lex_ident_db
Lex_ident_table
Lex_ident_trigger
Their comparison collation depends on the underlying
file system case sensitivity and on --lower-case-table-names
and can be either my_charset_bin or my_charset_utf8mb3_general1400_as_ci.
- Adding classes representing names of other database objects,
whose names have case insensitive comparison style,
using my_charset_utf8mb3_general1400_as_ci:
Lex_ident_column
Lex_ident_sys_var
Lex_ident_user_var
Lex_ident_sp_var
Lex_ident_ps
Lex_ident_i_s_table
Lex_ident_window
Lex_ident_func
Lex_ident_partition
Lex_ident_with_element
Lex_ident_rpl_filter
Lex_ident_master_info
Lex_ident_host
Lex_ident_locale
Lex_ident_plugin
Lex_ident_engine
Lex_ident_server
Lex_ident_savepoint
Lex_ident_charset
engine_option_value::Name
- All the mentioned Lex_ident_xxx classes implement a method streq():
if (ident1.streq(ident2))
do_equal();
This method works as a wrapper for CHARSET_INFO::streq().
- Changing a lot of "LEX_CSTRING name" to "Lex_ident_xxx name"
in class members and in function/method parameters.
- Replacing all calls like
system_charset_info->coll->strcasecmp(ident1, ident2)
to
ident1.streq(ident2)
- Taking advantage of the c++11 user defined literal operator
for LEX_CSTRING (see m_strings.h) and Lex_ident_xxx (see lex_ident.h)
data types. Use example:
const Lex_ident_column primary_key_name= "PRIMARY"_Lex_ident_column;
is now a shorter version of:
const Lex_ident_column primary_key_name=
Lex_ident_column({STRING_WITH_LEN("PRIMARY")});
* --ssl-verify-server-cert was not enabled explicitly, and
* CA was not specified, and
* fingerprint was not specified, and
* protocol is TCP, and
* no password was provided
insecure passwordless logins are common in test environment, let's
not break them. practically, it hardly makes sense to have strong
MitM protection if an attacker can simply login without a password.
Covers mariadb, mariadb-admin, mariadb-binlog, mariadb-dump
- make connect_to_db() return MYSQL*, we'll reuse the function for
connection pool.
- Remove variable 'mysql_connection', duplicated by variable 'mysql'
- do not attempt to start slave if connection did not succeed,#
and fix mysqldump.result
