Linux mariadb-client build does not accept Unicode characters

    XMLWordPrintable

    Details

      Description

      Since at least 10.5.12, but also affecting the latest 10.7.3, the prepackaged "mariadb-client" for Debian Linux does not accept typing of unicode characters (like e.g. German umlauts anymore). 10.3 did not have this problem.

      The client used to be built with readline, now it seems to be built with an "EditLine wrapper":

      $ mysql --help
      mysql  Ver 15.1 Distrib 10.7.3-MariaDB, for debian-linux-gnu (x86_64) using readline EditLine wrapper
      Copyright (c) 2000, 2018, Oracle, MariaDB Corporation Ab and others.
       
      Usage: mysql [OPTIONS] [database]
       
      Default options are read from the following files in the given order:
      /etc/my.cnf /etc/mysql/my.cnf ~/.my.cnf 
      The following groups are read: mysql mariadb-client client client-server client-mariadb
      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.
      The following specify which files/extra groups are read (specified before remaining options):
      --defaults-file=#         Only read default options from the given file #.
      --defaults-extra-file=#   Read this file after the global files are read.
      --defaults-group-suffix=# Additionally read default groups with # appended as a suffix.
       
        -?, --help          Display this help and exit.
        -I, --help          Synonym for -?
        --abort-source-on-error 
                            Abort 'source filename' operations in case of errors
        --auto-rehash       Enable automatic rehashing. One doesn't need to use
                            'rehash' to get table and field completion, but startup
                            and reconnecting may take a longer time. Disable with
                            --disable-auto-rehash.
                            (Defaults to on; use --skip-auto-rehash to disable.)
        -A, --no-auto-rehash 
                            No automatic rehashing. One has to use 'rehash' to get
                            table and field completion. This gives a quicker start of
                            mysql and disables rehashing on reconnect.
        --auto-vertical-output 
                            Automatically switch to vertical output mode if the
                            result is wider than the terminal width.
        -B, --batch         Don't use history file. Disable interactive behavior.

        --character-sets-dir=name 
                            Directory for character set files.
        --column-type-info  Display column type information.
        -c, --comments      Preserve comments. Send comments to the server. The
                            default is --skip-comments (discard comments), enable
                            with --comments.
        -C, --compress      Use compression in server/client protocol.
        -#, --debug[=#]     This is a non-debug version. Catch this and exit.
        --debug-check       Check memory and open file usage at exit.
        -T, --debug-info    Print some debug info at exit.
        -D, --database=name Database to use.
        --default-character-set=name 
                            Set the default character set.
        --delimiter=name    Delimiter to be used.
        -e, --execute=name  Execute command and quit. (Disables --force and history
                            file.)
        -E, --vertical      Print the output of a query (rows) vertically.
        -f, --force         Continue even if we get an SQL error. Sets
                            abort-source-on-error to 0
        -G, --named-commands 
                            Enable named commands. Named commands mean this program's
                            internal commands; see mysql> help . When enabled, the
                            named commands can be used from any line of the query,
                            otherwise only from the first line, before an enter.
                            Disable with --disable-named-commands. This option is
                            disabled by default.
        -i, --ignore-spaces Ignore space after function names.

                            Don't write line number for errors.
        -n, --unbuffered    Flush buffer after each query.
        --column-names      Write column names in results.
                            (Defaults to on; use --skip-column-names to disable.)
        -N, --skip-column-names

        --pager[=name]      Pager to use to display results. If you don't supply an
                            option, the default pager is taken from your ENV variable
                            PAGER. Valid pagers are less, more, cat [> filename],
                            etc. See interactive help (\h) also. This option does not
                            work in batch mode. Disable with --disable-pager. This
                            option is disabled by default.
        -p, --password[=name] 
                            Password to use when connecting to server. If password is
                            not given it's asked from the tty.
        -P, --port=#        Port number to use for connection or 0 for default to, in
                            order of preference, my.cnf, $MYSQL_TCP_PORT,

        --protocol=name     The protocol to use for connection (tcp, socket, pipe).
        -q, --quick         Don't cache result, print it row by row. This may slow
                            down the server if the output is suspended. Doesn't use
                            history file.
        -r, --raw           Write fields without conversion. Used with --batch.

        --ssl               Enable SSL for connection (automatically enabled with
                            other flags).
        --ssl-ca=name       CA file in PEM format (check OpenSSL docs, implies

                            hostname used when connecting. This option is disabled by
                            default.
        -t, --table         Output in table format.
        --tee=name          Append everything into outfile. See interactive help (\h)
                            also. Does not work in batch mode. Disable with
                            --disable-tee. This option is disabled by default.
        -u, --user=name     User for login if not current user.
        -U, --safe-updates  Only allow UPDATE and DELETE that uses keys.
        -U, --i-am-a-dummy  Synonym for option --safe-updates, -U.

        --select-limit=#    Automatic limit for SELECT when using --safe-updates.
        --max-join-size=#   Automatic limit for rows in a join when using
                            --safe-updates.
        --secure-auth       Refuse client connecting to server if it uses old
                            (pre-4.1.1) protocol.
        --server-arg=name   Send embedded server this as a parameter.

        --plugin-dir=name   Directory for client-side plugins.
        --default-auth=name Default authentication client-side plugin to use.
        --binary-mode       Binary mode allows certain character sequences to be
                            processed as data that would otherwise be treated with a
                            special meaning by the parser. Specifically, this switch
                            turns off parsing of all client commands except \C and
                            DELIMITER in non-interactive mode (i.e., when binary mode
                            is combined with either 1) piped input, 2) the --batch
                            mysql option, or 3) the 'source' command). Also, in
                            binary mode, occurrences of '\r\n' and ASCII '\0' are
                            preserved within strings, whereas by default, '\r\n' is
                            translated to '\n' and '\0' is disallowed in user input.
        --connect-expired-password 
                            Notify the server that this client is prepared to handle
                            expired password sandbox mode even if --batch was
                            specified.

      According to the mariadb wiki, editline is "known" to cause problems with special characters. I suggest the packaging uses readline again. Alternatively, maybe the editline based implementation can be fixed? MySQL used to have a similar problem in the past which since then has been repaired: https://bugs.mysql.com/bug.php?id=102806
