It’s backward incompatible change but we introduced the change. Because we marked this behavior as a bug.

Added Groonga::Plugin.names.

Improvements

Added Groonga::Plugin.ruby_suffix.
Groonga::Hash is used as the default table type when :key_type is specified in Groonga::Schema. Groonga::Array was used as the default table type. It’s a backward incompatible change. But nobody will not stumped. Because :key_type is specified but :type isn’t specified case is a bug of user’s program.

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

Improvements

Reduced build failure by automatically Groonga build. [Reported by SHIMADA Koji]
Added groonga-database-inspect command that inspects passed database. [Suggested by Genki Takiuchi]
Groonga::Database#tables ignores missing objects rather than raising an exception. Because the method is interested in only existing tables.

[table] Used normalizer for checking key normalization is enabled or not.

Added groonga-index-dump tool (experimental). This tool dumps infomations for each index from DB. Dumped informations are contained at “INDEX_NAME.dump” files in “TARGET_TABLE_NAME.index_INDEX_COLUMN_NAME”. e.g.)

$ 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
  column_create --table Video --name title --flags COLUMN_SCALAR --type ShortText

  load --table Video
  [
  {"_key":1,"title":"groonga Demo","tags":["IT","Server","groonga"]},
  {"_key":2,"title":"Ultra Baseball","tags":["Sports","Baseball"]},
  ]
$ groonga --file index-dump.sdf -n index-dump.db
$ groonga-index-dump --output-directory=path/to/index/ index-dump.db
$ cd path/to/index/
$ ls Tag.index_tags
  Baseball.dump  IT.dump       Server.dump  Sports.dump  groonga.dump
$ cat path/to/index/Tag.index_tags/groonga.dump
  index: Tag.index_tags	term: <groonga>	domain: Tag	range: Video	have_section: false	have_weight: false	have_position: false
   weight	position        term_frequency	record
   0    2     1   Video[ 1 ].tags

Added flag options to Groonga::IndexColumn#open_cursor. The flag options are :with_section, :with_weight, :with_position. They are enabled by default if each option is specified in creating a index column.

```
Returned Groonga::Array instead of Array by Table#sort. [GitHub: #8][Suggested by Genki Takiuchi] CAUTION: This is backward incompatible change. You need to use record.value to get the original record. The following code shows how to use old style:
```
result_since_2_1_0 = table.sort(["sort_key"])
result_before_2_1_0 = result_since_2_1_0.collect do |record|
  record.value
end
```
