4.0.6: 2014-11-06

Improvements

  • Supported Groonga 4.0.7. [GitHub#28]
    • Changed Groonga::Context#support_lzo? always returns false.
    • Added Groonga::Context#support_lz4?.
    • Supported :lz4 in Groonga::Table#define_column options.
    • Supported :lz4 in Groonga::VariableSizeColumn#compressed? options.
    • Added Groonga::LZ4Error.
    • [grndump] Supported COMPRESS_ZLIB and COMPRESS_LZ4 flags.
    • Added Groonga::TableKeySupport#token_filters.
    • Added Groonga::TableKeySupport#token_filters=.
    • Supported :token_filters in Groonga::Hash.create options.
    • Supported :token_filters in Groonga::PatriciaTrie.create options.
    • Supported :token_filters in Groonga::DoubleArrayTrie.create options.
    • Supported :token_filters in Groonga::Schema.create_table options.
    • Added Groonga::TokenFilterError.
    • [grndump] Supported token filters.

  • Stopped to require logger object as the first argument of Groonga::Logger.register when block is specified.

Fixes

  • [doc] Removed deprecated example. [GitHub#26] [Patch by ongaeshi]
  • Fixed a bug that a column assignment raises an error when you assign value with type A and then assign value type B again. [GitHub#27] [Patch by Daisuke Goto]
  • Fixed a memory leak in Groonga::PatriciaTrie#open_near_cursor.
  • Fixed a bug that you can access a column renamed by Groonga::Column#rename with old name. [GitHub#29] [Patch by Daisuke Goto]

4.0.5: 2014-10-05

Improvements

  • [windows] Added cross build task.
  • Added Groonga::DoubleArrayTrie#update. [GitHub#24] [Patch by Masafumi Yokoyama]
  • Added Groonga::Record#rename.
  • [windows] Disabled debug flags.

Fixes

  • Added :id => true option to Groonga::Table::KeySupport#delete. Groonga::Table::KeySupport#delete accepts both ID and key. If passed value is integer, it is handled as ID. But we can use Int32 as key. In the case, we can’t delete a record by key. Therefore, we added Groonga::Table::KeySupport#delete(id, :id => true) API. It introduces a backward incompatibility, but it is OK because the current API is a bug.

Thanks

  • Masafumi Yokoyama

4.0.4: 2014-08-29

Improvements

  • Supported Groonga 4.0.4 or later. Groonga 4.0.3 or older are not supported.

  procedure = Groonga[“TokenBigram”]
  p procedure.type == Groonga::ProcedureType::<span class="caps">TOKENIZER</span>  #=> true
  • Avoided a crash when Groonga::Record#inspct is called on exit. [GitHub#18] [Reported by Ippei Obayashi]
  • Updated Free Software Foundation address. [Masafumi Yokoyama]
  • Supported reference weight vector. It requires Groonga 4.0.4 or later.
  • Updated homepage in gemspec to use ranguba.org. [Masafumi Yokoyama]

$ cat index-dump.sdf
table_create —name Video —flags TABLE_HASH_KEY —key_type UInt32
table_create —name Tag —flags TABLE_HASH_KEY —key_type ShortText

]
$ groonga —file index-dump.sdf -n index-dump.db
$ groonga-index-dump —output-directory=path/to/index/ index-dump.db
