+Windows bug: happens when a new line is exactly at the right offset.
+The following options may be given as the first argument:
+--print-defaults Print the program argument list and exit.
+--no-defaults Don't read default options from any option file.
+--defaults-file=# Only read default options from the given file #.
+--defaults-extra-file=# Read this file after the global files are read.
+
+ --allow-suspicious-udfs
+ Allows use of UDFs consisting of only one symbol xxx()
+ without corresponding xxx_init() or xxx_deinit(). That
+ also means that one can load any function from any
+ library, for example exit() from libc.so
+ -a, --ansi Use ANSI SQL syntax instead of MySQL syntax. This mode
+ will also set transaction isolation level 'serializable'.
+ --auto-increment-increment[=#]
+ Auto-increment columns are incremented by this
+ --auto-increment-offset[=#]
+ Offset added to Auto-increment columns. Used when
+ auto-increment-increment != 1
+ --autocommit Set default value for autocommit (0 or 1)
+ (Defaults to on; use --skip-autocommit to disable.)
+ --automatic-sp-privileges
+ Creating and dropping stored procedures alters ACLs
+ (Defaults to on; use --skip-automatic-sp-privileges to disable.)
+ --back-log=# The number of outstanding connection requests MariaDB can
+ have. This comes into play when the main MariaDB thread
+ gets very many connection requests in a very short time
+ (Automatically configured unless set explicitly)
+ -b, --basedir=name Path to installation directory. All paths are usually
+ resolved relative to this
+ --big-tables Old variable, which if set to 1, allows large result sets
+ by saving all temporary sets to disk, avoiding 'table
+ full' errors. No longer needed, as the server now handles
+ this automatically. sql_big_tables is a synonym.
+ --bind-address=name IP address to bind to.
+ --binlog-annotate-row-events
+ Tells the master to annotate RBR events with the
+ statement that caused these events
+ (Defaults to on; use --skip-binlog-annotate-row-events to disable.)
+ --binlog-cache-size=#
+ The size of the transactional cache for updates to
+ transactional engines for the binary log. If you often
+ use transactions containing many statements, you can
+ increase this to get more performance
+ --binlog-checksum=name
+ Type of BINLOG_CHECKSUM_ALG. Include checksum for log
+ events in the binary log. One of: NONE, CRC32
+ --binlog-commit-wait-count=#
+ If non-zero, binlog write will wait at most
+ binlog_commit_wait_usec microseconds for at least this
+ many commits to queue up for group commit to the binlog.
+ This can reduce I/O on the binlog and provide increased
+ opportunity for parallel apply on the slave, but too high
+ a value will decrease commit throughput.
+ --binlog-commit-wait-usec=#
+ Maximum time, in microseconds, to wait for more commits
+ to queue up for binlog group commit. Only takes effect if
+ the value of binlog_commit_wait_count is non-zero.
+ --binlog-direct-non-transactional-updates
+ Causes updates to non-transactional engines using
+ statement format to be written directly to binary log.
+ Before using this option make sure that there are no
+ dependencies between transactional and non-transactional
+ tables such as in the statement INSERT INTO t_myisam
+ SELECT * FROM t_innodb; otherwise, slaves may diverge
+ from the master.
+ --binlog-do-db=name Tells the master it should log updates for the specified
+ database, and exclude all others not explicitly
+ mentioned.
+ --binlog-file-cache-size=#
+ The size of file cache for the binary log
+ --binlog-format=name
+ What form of binary logging the master will use: either
+ ROW for row-based binary logging, STATEMENT for
+ statement-based binary logging, or MIXED. MIXED is
+ statement-based binary logging except for those
+ statements where only row-based is correct: those which
+ involve user-defined functions (i.e. UDFs) or the UUID()
+ function; for those, row-based binary logging is
+ automatically used.
+ --binlog-ignore-db=name
+ Tells the master that updates to the given database
+ should not be logged to the binary log.
+ --binlog-optimize-thread-scheduling
+ Run fast part of group commit in a single thread, to
+ optimize kernel thread scheduling. On by default. Disable
+ to run each transaction in group commit in its own
+ thread, which can be slower at very high concurrency.
+ This option is mostly for testing one algorithm versus
+ the other, and it should not normally be necessary to
+ change it.
+ (Defaults to on; use --skip-binlog-optimize-thread-scheduling to disable.)
+ --binlog-row-event-max-size=#
+ The maximum size of a row-based binary log event in
+ bytes. Rows will be grouped into events smaller than this
+ size if possible. The value has to be a multiple of 256.
+ --binlog-row-image=name
+ Controls whether rows should be logged in 'FULL',
+ 'NOBLOB' or 'MINIMAL' formats. 'FULL', means that all
+ columns in the before and after image are logged.
+ 'NOBLOB', means that mysqld avoids logging blob columns
+ whenever possible (eg, blob column was not changed or is
+ not part of primary key). 'MINIMAL', means that a PK
+ equivalent (PK columns or full row if there is no PK in
+ the table) is logged in the before image, and only
+ changed columns are logged in the after image. (Default:
+ FULL).
+ --binlog-stmt-cache-size=#
+ The size of the statement cache for updates to
+ non-transactional engines for the binary log. If you
+ often use statements updating a great number of rows, you
+ can increase this to get more performance.
+ --bootstrap Used by mysql installation scripts.
+ --bulk-insert-buffer-size=#
+ Size of tree cache used in bulk insert optimisation. Note
+ that this is a limit per thread!
+ --character-set-client-handshake
+ Don't ignore client side character set value sent during
+ handshake.
+ (Defaults to on; use --skip-character-set-client-handshake to disable.)
+ --character-set-filesystem=name
+ Set the filesystem character set.
+ -C, --character-set-server=name
+ Set the default character set.
+ --character-sets-dir=name
+ Directory where character sets are
+ -r, --chroot=name Chroot mysqld daemon during startup.
+ --collation-server=name
+ Set the default collation.
+ --column-compression-threshold=#
+ Minimum column data length eligible for compression
+ --column-compression-zlib-level=#
+ zlib compression level (1 gives best speed, 9 gives best
+ compression)
+ --column-compression-zlib-strategy=name
+ The strategy parameter is used to tune the compression
+ algorithm. Use the value DEFAULT_STRATEGY for normal
+ data, FILTERED for data produced by a filter (or
+ predictor), HUFFMAN_ONLY to force Huffman encoding only
+ (no string match), or RLE to limit match distances to one
+ (run-length encoding). Filtered data consists mostly of
+ small values with a somewhat random distribution. In this
+ case, the compression algorithm is tuned to compress them
+ better. The effect of FILTERED is to force more Huffman
+ coding and less string matching; it is somewhat
+ intermediate between DEFAULT_STRATEGY and HUFFMAN_ONLY.
+ RLE is designed to be almost as fast as HUFFMAN_ONLY, but
+ give better compression for PNG image data. The strategy
+ parameter only affects the compression ratio but not the
+ correctness of the compressed output even if it is not
+ set appropriately. FIXED prevents the use of dynamic
+ Huffman codes, allowing for a simpler decoder for special
+ applications.
+ --column-compression-zlib-wrap
+ Generate zlib header and trailer and compute adler32
+ check value. It can be used with storage engines that
+ don't provide data integrity verification to detect data
+ corruption.
+ --completion-type=name
+ The transaction completion type. One of: NO_CHAIN, CHAIN,
+ RELEASE
+ --concurrent-insert[=name]
+ Use concurrent insert with MyISAM. One of: NEVER, AUTO,
+ ALWAYS
+ --console Write error output on screen; don't remove the console
+ window on windows.
+ --core-file Write core on errors.
+ -h, --datadir=name Path to the database root directory
+ --date-format=name The DATE format (ignored)
+ --datetime-format=name
+ The DATETIME format (ignored)
+ --deadlock-search-depth-long=#
+ Long search depth for the two-step deadlock detection
+ --deadlock-search-depth-short=#
+ Short search depth for the two-step deadlock detection
+ --deadlock-timeout-long=#
+ Long timeout for the two-step deadlock detection (in
+ microseconds)
+ --deadlock-timeout-short=#
+ Short timeout for the two-step deadlock detection (in

+ --default-regex-flags=name
+ Default flags for the regex library. Any combination of:

+ --default-storage-engine=name
+ The default storage engine for new tables

+ Set the default time zone.
+ --default-tmp-storage-engine=name
+ The default storage engine for user-created temporary
+ tables
+ --default-week-format=#
+ The default week format used by WEEK() functions
+ --delay-key-write[=name]
+ Specifies how MyISAM tables handles CREATE TABLE
+ DELAY_KEY_WRITE. If set to ON, the default, any DELAY KEY
+ WRITEs are honored. The key buffer is then flushed only
+ when the table closes, speeding up writes. MyISAM tables
+ should be automatically checked upon startup in this
+ case, and --external locking should not be used, as it
+ can lead to index corruption. If set to OFF, DELAY KEY
+ WRITEs are ignored, while if set to ALL, all new opened
+ tables are treated as if created with DELAY KEY WRITEs
+ enabled.
+ --delayed-insert-limit=#
+ After inserting delayed_insert_limit rows, the INSERT
+ DELAYED handler will check if there are any SELECT
+ statements pending. If so, it allows these to execute
+ before continuing.
+ --delayed-insert-timeout=#
+ How long a INSERT DELAYED thread should wait for INSERT
+ statements before terminating
+ --delayed-queue-size=#
+ What size queue (in rows) should be allocated for
+ handling INSERT DELAYED. If the queue becomes full, any
+ client that does INSERT DELAYED will wait until there is
+ room in the queue again
+ --div-precision-increment=#
+ Precision of the result of '/' operator will be increased
+ on that value
+ --encrypt-binlog Encrypt binary logs (including relay logs)
+ --encrypt-tmp-disk-tables
+ Encrypt temporary on-disk tables (created as part of
+ query execution)
+ --encrypt-tmp-files Encrypt temporary files (created for filesort, binary log
+ cache, etc)
+ --enforce-storage-engine=name
+ Force the use of a storage engine for new tables
+ --event-scheduler[=name]
+ Enable the event scheduler. Possible values are ON, OFF,
+ and DISABLED (keep the event scheduler completely
+ deactivated, it cannot be activated run-time)
+ --expensive-subquery-limit=#
+ The maximum number of rows a subquery may examine in
+ order to be executed during optimization and used for
+ constant optimization
+ --expire-logs-days=#
+ If non-zero, binary logs will be purged after
+ expire_logs_days days; possible purges happen at startup
+ and at binary log rotation
+ --explicit-defaults-for-timestamp
+ This option causes CREATE TABLE to create all TIMESTAMP
+ columns as NULL with DEFAULT NULL attribute, Without this
+ option, TIMESTAMP columns are NOT NULL and have implicit
+ DEFAULT clauses.
+ --external-locking Use system (external) locking (disabled by default).
+ With this option enabled you can run myisamchk to test
+ (not repair) tables while the MySQL server is running.
+ Disable with --skip-external-locking.
+ --extra-max-connections=#
+ The number of connections on extra-port
+ --extra-port=# Extra port number to use for tcp connections in a
+ one-thread-per-connection manner. 0 means don't use
+ another port
+ --flashback Setup the server to use flashback. This enables binary
+ log in row mode and will enable extra logging for DDL's
+ needed by flashback feature
+ --flush Flush MyISAM tables to disk between SQL commands
+ --flush-time=# A dedicated thread is created to flush all tables at the
+ given interval
+ --ft-boolean-syntax=name
+ List of operators for MATCH ... AGAINST ( ... IN BOOLEAN
+ MODE)
+ --ft-max-word-len=# The maximum length of the word to be included in a
+ FULLTEXT index. Note: FULLTEXT indexes must be rebuilt
+ after changing this variable
+ --ft-min-word-len=# The minimum length of the word to be included in a
+ FULLTEXT index. Note: FULLTEXT indexes must be rebuilt
+ after changing this variable
+ --ft-query-expansion-limit=#
+ Number of best matches to use for query expansion
+ --ft-stopword-file=name
+ Use stopwords from this file instead of built-in list
+ --gdb Set up signals usable for debugging. Deprecated, use
+ --general-log Log connections and queries to a table or log file.
+ Defaults logging to a file 'hostname'.log or a table
+ mysql.general_logif --log-output=TABLE is used.
+ --general-log-file=name
+ Log connections and queries to given file
+ --getopt-prefix-matching
+ Recognize command-line options by their unambiguos
+ prefixes.
+ (Defaults to on; use --skip-getopt-prefix-matching to disable.)
+ --group-concat-max-len=#
+ The maximum length of the result of function
+ GROUP_CONCAT()
+ --gtid-domain-id=# Used with global transaction ID to identify logically
+ independent replication streams. When events can
+ propagate through multiple parallel paths (for example
+ multiple masters), each independent source server must
+ use a distinct domain_id. For simple tree-shaped
+ replication topologies, it can be left at its default, 0.
+ --gtid-ignore-duplicates
+ When set, different master connections in multi-source
+ replication are allowed to receive and process event
+ groups with the same GTID (when using GTID mode). Only
+ one will be applied, any others will be ignored. Within a
+ given replication domain, just the sequence number will
+ be used to decide whether a given GTID has been already
+ applied; this means it is the responsibility of the user
+ to ensure that GTID sequence numbers are strictly
+ increasing.
+ --gtid-pos-auto-engines=name
+ List of engines for which to automatically create a
+ mysql.gtid_slave_pos_ENGINE table, if a transaction using
+ that engine is replicated. This can be used to avoid
+ introducing cross-engine transactions, if engines are
+ used different from that used by table
+ mysql.gtid_slave_pos
+ --gtid-strict-mode Enforce strict seq_no ordering of events in the binary
+ log. Slave stops with an error if it encounters an event
+ that would cause it to generate an out-of-order binlog if
+ executed.
+ -?, --help Display this help and exit.
+ --histogram-size=# Number of bytes used for a histogram. If set to 0, no
+ histograms are created by ANALYZE.
+ --histogram-type=name
+ Specifies type of the histograms created by ANALYZE.
+ Possible values are: SINGLE_PREC_HB - single precision

+ --init-file=name Read SQL commands from this file at startup
+ --init-rpl-role=name
+ Set the replication role. One of: MASTER, SLAVE
+ --init-slave=name Command(s) that are executed by a slave server each time
+ the SQL thread starts
+ --interactive-timeout=#
+ The number of seconds the server waits for activity on an
+ interactive connection before closing it
+ --join-buffer-size=#
+ The size of the buffer that is used for joins
+ --join-buffer-space-limit=#
+ The limit of the space for all join buffers used by a
+ query
+ --join-cache-level=#
+ Controls what join operations can be executed with join
+ buffers. Odd numbers are used for plain join buffers
+ while even numbers are used for linked buffers
+ --keep-files-on-create
+ Don't overwrite stale .MYD and .MYI even if no directory
+ is specified
+ --key-buffer-size=# The size of the buffer used for index blocks for MyISAM
+ tables. Increase this to get better index handling (for
+ all reads and multiple writes) to as much as you can
+ afford
+ --key-cache-age-threshold=#
+ This characterizes the number of hits a hot block has to
+ be untouched until it is considered aged enough to be
+ downgraded to a warm block. This specifies the percentage
+ ratio of that number of hits to the total number of
+ blocks in key cache
+ --key-cache-block-size=#
+ The default size of key cache blocks
+ --key-cache-division-limit=#
+ The minimum percentage of warm blocks in key cache
+ --key-cache-file-hash-size=#
+ Number of hash buckets for open and changed files. If
+ you have a lot of MyISAM files open you should increase
+ this for faster flush of changes. A good value is
+ probably 1/10 of number of possible open MyISAM files.
+ --key-cache-segments=#
+ The number of segments in a key cache
+ -L, --language=name Client error messages in given language. May be given as
+ a full path. Deprecated. Use --lc-messages-dir instead.
+ --large-pages Enable support for large pages

+ names for --log-bin, --log-bin-index, --relay-log,
+ --relay-log-index, --general-log-file,
+ --log-slow-query-log-file, --log-error-file, and
+ --pid-file
+ --log-bin[=name] Log update queries in binary format. Optional argument
+ should be name for binary log. If not given
+ 'datadir'/'log-basename'-bin or 'datadir'/mysql-bin will
+ be used (the later if --log-basename is not specified).
+ We strongly recommend to use either --log-basename or
+ specify a filename to ensure that replication doesn't
+ stop if the real hostname of the computer changes.
+ --log-bin-compress Whether the binary log can be compressed
+ --log-bin-compress-min-len[=#]
+ Minimum length of sql statement(in statement mode) or
+ record(in row mode)that can be compressed.
+ --log-bin-index=name
+ File that holds the names for last binary log files.
+ --log-bin-trust-function-creators
+ If set to FALSE (the default), then when --log-bin is
+ used, creation of a stored function (or trigger) is
+ allowed only to users having the SUPER privilege and only
+ if this stored function (trigger) may not break binary
+ logging. Note that if ALL connections to this server
+ ALWAYS use row-based binary logging, the security issues
+ do not exist and the binary logging cannot break, so you
+ can safely set this to TRUE
+ --log-disabled-statements=name
+ Don't log certain types of statements to general log. Any
+ combination of: slave, sp
+ --log-error[=name] Log errors to file (instead of stdout). If file name is
+ not specified then 'datadir'/'log-basename'.err or the

+ --log-short-format Don't log extra information to update and slow-query
+ logs.
+ --log-slave-updates Tells the slave to log the updates from the slave thread

+ plan to daisy-chain the slaves.
+ --log-slow-admin-statements
+ Log slow OPTIMIZE, ANALYZE, ALTER and other
+ administrative statements to the slow log if it is open.
+ Resets or sets the option 'admin' in

+ filesort_priority_queue, full_join, full_scan,
+ not_using_index, query_cache, query_cache_miss, tmp_table,
+ tmp_table_on_disk

+ Write to slow log every #th slow query. Set to 1 to log
+ everything. Increase it to reduce the size of the slow or
+ the performance impact of slow logging
+ --log-slow-slave-statements
+ Log slow statements executed by slave thread to the slow
+ log if it is open. Resets or sets the option 'slave' in
+ log_slow_disabled_statements
+ --log-slow-verbosity=name
+ Verbosity level for the slow log. Any combination of:
+ innodb, query_plan, explain
+ --log-tc=name Path to transaction coordinator log (used for
+ transactions that affect more than one storage engine,
+ when binary log is disabled).
+ --log-tc-size=# Size of transaction coordinator log.
+ -W, --log-warnings[=#]
+ Log some not critical warnings to the general log
+ file.Value can be between 0 and 11. Higher values mean
+ more verbosity
+ --long-query-time=# Log all queries that have taken more than long_query_time
+ seconds to execute to the slow query log file. The
+ argument will be treated as a decimal value with
+ microsecond precision
+ --low-priority-updates
+ INSERT/DELETE/UPDATE has lower priority than selects
+ --lower-case-table-names[=#]
+ If set to 1 table names are stored in lowercase on disk
+ and table names will be case-insensitive. Should be set
+ to 2 if you are using a case insensitive file system
+ --master-info-file=name
+ The location and name of the file that remembers the

+ grouping fields can be extracted from cond. If there is any it prepares it
+ for pushing using grouping_field_transformer_for_where and if it happens to
+ be a conjunct of cond it removes it from cond. It saves the result of
+ removal in remaining_cond.
+ The extracted condition is saved in cond_pushed_into_where of this select.
+
+ @note

message:
MDEV-15373 engine gtid_slave_pos table name disobeys lower-case-table-names
Replicated transaction extra gtid statement on slave failed to specify
an engine gtid_slave_pos name correctly. In case lower-case-table-names > 0
the InnoDB table name was generated to reproduce the lower-case-table-names=0 version
which is of mixed cases.
In rpl.rpl_mdev12179 test run this triggered a failure to DROP table which
was due to the innodb table handle was not closed:
InnoDB: Waited XYZ seconds for ref-count on table: `mysql`.`gtid_slave_pos_innodb`
on windows.
The closing issue was caused by having the table registered twice in the table cache,
for its lower- and mixed- case name versions. The DROP-table handler closed only
only one of the cache item to leave the 2nd one active.
(On Linux a failure occurs earlier at attempt to open an expected lower-cased table:
Last_Error: Error during XID COMMIT: failed to update GTID state in mysql.gtid_slave_pos: 1146: Table 'mysql.gtid_slave_pos_InnoDB' doesn't exist
but the table's name as the message shows is not in the right case).
Fixed with consulting lower-case-table-names when the engine gtid-slave-pos table
is created.
Note the lower-case-table-names=a-value created table will not recognized when next
the lower case option changes to a different value.

message:
MDEV-16104 Server crash in JOIN::fix_all_splittings_in_plan
upon select with view and subqueries
This bug occurred when a splittable materialized derived/view
were used inside another splittable materialized derived/view.
The bug happened because the function JOIN::fix_all_splittings_in_plan()
was called at the very beginning of the optimization phase 2 at
the moment when the plan structure of the embedding derived/view
were not valid. The proper position for this call is the very
end of the optimization phase 1.

message:
MDEV-16088: Pushdown into materialized views/derived tables doesn't
work in the IN subqueries
The pushdown into the materialized derived table/view wasn't done because
optimize() for the derived was called before any conditions that can
be pushed down were extracted. So optimize() in
convert_join_subqueries_to_semijoins() method is called too early and is
unnecessary. The second optimize() call in mysql_handle_single_derived()
is enough.
