safety first - tell mariadb client not to execute dangerous
cli commands, they cannot be present in the dump anyway.
wrapping the command in /*!999999 ..... */ guarantees that
if a non-mariadb-cli client loads the dump and sends it to the
server - the server will ignore the command it doesn't understand
Previously the correct SQL mode for a stored routine or
package was only set before doing the CREATE part, this
worked out for PROCEDUREs and FUNCTIONs, but with ORACLE
mode specific PACKAGEs the DROP also only works in ORACLE
mode.
Moving the setting of the sql_mode a few lines up to happen
right before the DROP statement is writen fixes this.
Per review by Serg, include start row with new line.
We are hoping we haven't annoyed people that prefered the old
way.
Adding an option for new lines seems like over-engineering in advance.
So if there are complaints, let them be known (JIRA), and we'll add
this under an option.
Test cases updated.
Currently, mysqldump --extended-insert outputs all rows on a single line,
which makes it difficult to use with various Unix command-line utilities
such as grep and diff.
We change mysqldump to emit a linebreak between each row, that would make
it easier to work with, without significantly affecting dump or restore
performance, or affecting compatibility.
Closes: #1865
This patch changes the main name of 3 byte character set from utf8 to
utf8mb3. New old_mode UTF8_IS_UTF8MB3 is added and set TRUE by default,
so that utf8 would mean utf8mb3. If not set, utf8 would mean utf8mb4.
