Release 4.1.1 - 2015-01-29#

Improvements#

  • [windows] Improved to show error message instead of error code. It’s easy to understand.

  • [experimental][windows] Supported small start file size for database file. In previous versions, Groonga consumed larger initial file size on windows in contrast to UNIX like environment. To enable this feature, use GRN_IO_VERSION=1 environment variable. This feature isn’t enabled by default because it is in experimental stage.

  • Supported SUM, MIN, MAX, AVG feature for drilldown. This feature is supported by extending newer drilldown syntax which supports label. Specify SUM, MIN, MAX or AVG for drilldown_calc_types and target column for drilldown_calc_target. The return value is calculated based on drilldown result in group.

  • [experimental] Added --with-jemalloc option to use jemalloc for malloc()/free(). It’ll improve performance on multi-threading usage. For example, the performance of groonga executable file or Mroonga will be improved. Note that this feature doesn’t affect to groonga-httpd because groonga-httpd uses multi-process model instead of multi-threading.

  • groonga-httpd: Supported long error message over 2048 bytes. By this change, long error message (>2048) is not truncated.

  • [dump] Supported streaming output.

Fixes#

  • Fixed mismatch between error code and error message when strerror() is failed. There was a case that Groonga shows incorrect error code as syscall error.

  • Fixed to show errno in error message when unknow error is occurred.

  • [windows] Fixed to return proper error code.

  • Fixed a bug that there is only one section for multi-column index for match_columns, it doesn’t return correct search results. For example, consider the case that there is multi-column index which is named as memo_index for title column and content column. Thus, this bug occurs when memo_index[0] which means index for title column is specified for match_columns.

  • mecab: Added workaround for mecab_strerror(NULL) on MeCab 0.993. Without this workaround, Groonga aborts if there is no MeCab dictionary. [Reported by Shuhei Tanuma]

  • groonga-httpd: Fixed a bug that custom log file is ignored.

  • groonga-httpd: Fixed a bug that empty dump doesn’t return.

Thanks#

Release 4.1.0 - 2015-01-09#

It’s a bug fix release of 4.0.9.

If you have already upgraded to 4.0.9, please upgrade to 4.1.0. And re-create your all indexes. You can re-create your indexes by removing and re-creating your indexes such as:

column_remove TABLE INDEX_COLUMN
column_create TABLE INDEX_COLUMN COLUMN_INDEX|...

See also

Note

If you didn’t change your indexes by Groonga 4.0.9, you don’t need to re-create your indexes. “change” means “add”, “remove” and “update”. If you use your indexes only for “search” by Groonga 4.0.9, you don’t need to re-create your indexes.

Fixes#

  • Fixed a bug that index may be broken. But the following bug fixed in Groonga 4.0.9 is re-appeared.

    • Fixed a crash bug that may be occurred by deleting or updating many indexed values at once. [groonga-dev,02942] [Reported by kashihara]

Release 4.0.9 - 2014-12-29#

Caution

Use 4.1.0 instead of 4.0.9. 4.0.9 has a serious bug that may break index.

Improvements#

  • [groonga-httpd] Marked as stable.

  • [doc] Described about groonga-token-filter-stem package. [GitHub#259] [Patch by Masafumi Yokoyama]

  • [build] Supported make install without make. [Reported by akira yamada]

  • [experimental] Added request_cancel command that cancels running request.

  • [experimental] Added grn_db_recover().

  • Supported indexing vector of fixed size data such as vector of UInt64. [groonga-dev,03014] [Reported by funa 1g]

  • [experimental] Added grndb.

  • [deb] Supported armhf architecture.

  • [Groonga HTTP server] Supported HEAD.

  • [doc] Updated Introduction. [GitHub#270] [Patch by Yuya TAMANO]

  • [doc] Updated Others. [GitHub#271] [Patch by Hiroshi Hatake]

  • [TokenFilterStem] Supported token that consists with only upper-case alphabets, digits, - and '. It means that TokenFilterStem can work with MySQL compatible normalizers.

  • [truncate] Supported column.

  • [truncate] Changed parameter name to target_name from table. table parameter can be used for backward compatibility but it shouldn’t used for newly written code.

  • Exported grn_column_truncate().

  • Added lock_clear.

  • Marked clearlock deprecated.

  • [backward incompatible] Stopped to set world writable permission for newly created files on umask(0) environment such as daemoned groonga-httpd. It’s a backward incompatible change but done because the previous behavior has a security risk.

Fixes#

  • Fixed build error on BSD based system. [GitHub#253] [Reported by Hiroshi Hatake]

  • Fixed build error on OS X. [GitHub#253] [Reported by Hiroshi Hatake]

  • Fixed a regression bug that equal operation against nonexistent reference always matches.

  • Fixed a crash bug that may be occurred by deleting or updating many indexed values at once. [groonga-dev,02942] [Reported by kashihara]

  • Fixed a regression bug that static index construction doesn’t work on BSD based system. [GitHub#264] [Reported by Ayumu Osanai]

  • Fixed a bug that --with-libstemmer configure option is ignored.

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 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 server 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 executable file.

  • 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]
