[logical_select](/doc/reference/commands/logical_select.html) Added new argument `--load_table`, `--load_columns` and `--load_values`. + +* [groonga executable file](/doc/reference/executables/groonga.html) Added a new option `--log-flags`. + +* Fixed a memory leak when occurs index update error. + +* [Normalizers](/doc/reference/normalizers.html) Fixed a bug that stateless normalizers and stateful normalizers return wrong results when we use them at the same time. + + * Stateless normalizers are below. + + * ``unify_kana`` + * ``unify_kana_case`` + * ``unify_kana_voiced_sound_mark`` + * ``unify_hyphen`` + * ``unify_prolonged_sound_mark`` + * ``unify_hyphen_and_prolonged_sound_mark`` + * ``unify_middle_dot`` + + * Stateful normalizers are below. + + * ``unify_katakana_v_sounds`` + * ``unify_katakana_bu_sound`` + * ``unify_to_romaji`` + +### [logical_select](/doc/reference/commands/logical_select.html) Added new argument `--load_table`, `--load_columns` and `--load_values`. + +We can store a result of `logical_select` in a table that specifying `--load_table`. + +`--load_values` option specifies columns of result of `logical_select`. + +`--load_columns` options specifies columns of table that specifying `--load_table`. + +In this way, you can store values of columns that specifying with `--load_values` into columns that specifying with `--load_columns`. + +For example, we can store `_id` and `timestamp` that a result of `logical_select` in a Logs table specified by `--load_table` as below. + +``` +table_create Logs_20150203

file](/doc/reference/executables/groonga.html) Added a new option `--log-flags`. + +We can specify output items of a log of the Groonga. + +We can output as below items. + +* Timestamp +* Log message +* Location(the location where the log was output) +* Process id +* Thread id + +We can specify prefix as below. + +* ``+`` + + * This prefix means that "add the flag". + +* ``-`` + + * This prefix

``all`` + + * This flag specifies all flags except ``none`` and ``default`` flags. + +* ``default`` + + * Output a timestamp and log messages into the log. + +We can also specify multiple log flags by separating flags with ``|``. + +For example, we can output process id and thread id additional as below. + +``` +Execute command +% groonga --log-path groonga.log --log-flags "+pid|+thread_id"
