Release 4.0.8 - 2014/11/29

Improvements

  • [deb] Supported Ubuntu 12.04 again because Travis-CI runs on it.
  • [mruby] Supported pretty print - "pp" for debugging. And supported to show internal objects more descriptive format when inspecting it.
  • Supported full text search query without index if one column is specified for --match_columns even though sequential search is executed by --query and --match_columns combination. [groonga-dev,02902] [Reported by Atsushi Shinoda]
  • [experimental] in_values supports auto sequential search mode. There is a case that sequential search is faster than index search when the number of narrowed down records is small enough in contrast to the number of expected records to narrow down by in_values with AND operation which use indexes. The value of GRN_IN_VALUES_TOO_MANY_INDEX_MATCH_RATIO is used as threshold whether Groonga execute sequential search or search with indexes in such a case.
  • [mruby] Supported to load relative path of script.
  • Supported test suite to write query optimizer test more easily with mruby enabled build.
  • Supported offline index construction for token filters. [GitHub#239] [Patch by Naoya Murakami]
  • [experimental] between supports auto sequential search mode. Use the value of GRN_BETWEEN_TOO_MANY_INDEX_MATCH_RATIO as threshold. Basic concept is similar to GRN_IN_VALUES_TOO_MANY_INDEX_MATCH_RATIO.
  • [experimental] Supported multiple drilldowns for :doc:/reference/command/select command. The syntax is extended to support this feature. The new one is --drilldown[LABEL1].keys COLUMN1,COLUMN2 for keys, --drilldown[LABEL1].output_columns _value.COLUMN1,_value.COLUMN2,_nsubrecs for output columns. In the previous versions, a client application must implement by oneself for drilldown by multiple keys. Use _key[N] for --drilldown[LABEL1].output_columns to show original value of key in records.
  • Supported to search 'reference_column @ "query"' without index.
  • [experimental] Added range_filter command. It is faster than select command to fetch specific range of records in most cases, because it doesn't returns the number of matched records. There are limitations which doesn't support drilldown and so on. Thus, range_filter is suitable for extracting first N records in specific range for ranking or something else.
  • [httpd] Supported groonga-httpd on windows.
  • Supported vector column for drilldown.
  • [deb] Changed groonga-httpd as default HTTP server package. groonga-server-http is deprecated. Note that groonga HTTPサーバー functionality itself is still exists in Groonga. If you just want to use simple HTTP server in traditional way, specify proper arguments by command line for groonga command.
  • Added configuration file for Windows CI on AppVeyor. [groonga-dev,02970,02981] [Patch by Hiroshi Hatake]

Fixes

  • [doc] Fixed duplicated execution example path about table_create. [GitHub groonga.org#14] [Reported by Masafumi Yokoyama]
  • Fixed a bug that nested indexed full text search against X._key returns empty results.
  • Fixed flags parameter which is strict in BSD mkostemp(3). [GitHub#240] [Patch by Jun Kuriyama]
  • Fixed a bug that select command reports invalid value type (table) as index column value type. It was fixed to UInt32. Note that it affects only the value of response header. The search results is not changed at all.
  • Fixed a bug that compare operations such as <, <=, >, >=, != with Time and String type returns invalid results.
  • Fixed a bug that prefix search can't be executed against single character such as "x*". [GitHub#242] [Patch by Naoya Murakami]
  • Fixed a memory leak on drilldown ShortText value with --filter.
  • Fixed missing "," for "DDL:set_token_filters" log. [Reported by Naoya Murakami]

  • [load] Supported to update existing record in TABLE_NO_KEY by specifying a record by _id.
  • Added TokenFilterStem token filter plugin. It provides stemming feature. To use this token filter, you need to install libstemmer library.

  • Fixed a crash bug when deleting a record. If the table of the record has _key and _key is indexed from two or more index columns, deleting causes a crash.
