All notable changes to this project (at least, from v3.0.0 onwards) are documented in this file.
- Fixed total count of results in pagination information for Manticore 5.0+, by disabling the cutoff limit. (#1239).
- ThinkingSphinx::Processor, a public interface to perform index-related operations on model instances or model name/id combinations. In collaboration with @akostadinov (#1215).
- Confirmed support by testing against Ruby 3.1 and 3.2 by @jdelStrother (#1237).
- Fix YAML loading, by @aepyornis (#1217).
- Further fixes for File.exist? instead of the deprecated File.exists?, by @funsim (#1221) and @graaf (1233).
- Treat unknown column errors as QueryErrors, so retrying the query occurs automatically.
- Fix MariaDB error handling.
- Rails 7 support, including contributions from @anthonyshull in #1205.
- Confirmed support by testing against Manticore 4.0 and Sphinx 3.4.
- Include instance_exec in ThinkingSphinx::Search::CORE_METHODS by @jdelStrother in #1210.
- Use File.exist? instead of the deprecated File.exists? (#1211).
- StaleIdsExceptions now include a URL in their error message with recommendations on how to resolve the problem.
- Fire real-time callbacks on
after_commit(including deletions) to ensure data is fully persisted to the database before updating Sphinx. More details in #1204.
- Ensure Thinking Sphinx's ActiveRecord components are loaded by either Rails' after_initialise hook or ActiveSupport's on_load notification, because the order of these two events are not consistent.
- Remove
app/indicesfrom eager_load_paths in Rails 4.2 and 5, to match the behaviour in 6.
- Ensure ActiveRecord components are loaded for rake tasks, but only after the Rails application has initialised. More details in #1199.
- Confirmed support for Ruby 3.0.
- Orphaned records in real-time indices can now be cleaned up without running
rails ts:rebuild. Disabled by default, can be enabled by settingreal_time_tidyto true per environment inconfig/thinking_sphinx.yml(and will needts:rebuildto restructure indices upon initial deploy). More details in #1192.
- Avoid loading ActiveRecord during Rails initialisation so app configuration can still have an impact (@jdelStrother in #1194).
- Remove
app/indices(in both the Rails app and engines) from Rails' eager load paths, which was otherwise leading to indices being loaded more than once. (See #1191 and #1195).
- Support for Sphinx v3.3 and Manticore v3.5.
- Support for Rails 6.1 (via joiner v0.6.0).
enable_staris no longer available as a configuration option, as it's been enabled by default in Sphinx since v2.2.2, and is no longer allowed in Sphinx v3.3.1.- All timestamp attributes are now considered plain integer values from Sphinx's perspective. Sphinx was already expecting integers, but since Sphinx v3.3.1 it doesn't recognise timestamps as a data type. There is no functional difference with this change - Thinking Sphinx was always converting times to their UNIX epoch integer values.
- Allow configuration of the maximum statement length (@kalsan in #1179).
- Respect
:pathvalues to navigate associations for Thinking Sphinx callbacks on SQL-backed indices. Discussed in #1182.
- Don't attempt to update delta flags on frozen model instances.
- New interface for adding callbacks to indexed models (which is no longer done automatically). Discussed in #1173 and committed via #1175. This is a breaking change - you will need to add these callbacks. See the full release notes for examples.
- Fields and attributes can be overriden - whichever's defined last with a given name is the definition that's used. This is an edge case, but useful if you want to override any of the default fields/indices. (Requested by @kalsan in #1172.)
- Custom index_set_class implementations can now expect the
:instancesoption to be set alongside:classes, which is useful in cases to limit the indices returned if you're splitting index data for given classes/models into shards. (Introduced in PR #1171 after discussions with @lunaru in #1166.)
- Sphinx 2.2.11 or newer is required, or Manticore 2.8.2 or newer.
- Ruby 2.4 or newer is required.
- Rails 4.2 or newer is required.
- Remove internal uses of
send, replaced withpublic_sendas that's available in all supported Ruby versions. - Deletion statements are simplified by avoiding the need to calculate document keys/offsets (@njakobsen via #1134).
- Real-time data is deleted before replacing it, to avoid duplicate data when offsets change (@njakobsen via #1134).
- Use
reference_nameas per customindex_set_classdefinitions. Previously, the class method was called onThinkingSphinx::IndexSeteven if a custom subclass was configured. (As per discussions with @kalsan in #1172.)
- Automatically remove
app/indicesfrom Zeitwerk's autoload paths in Rails 6.0 onwards (if using Zeitwerk as the autoloader).
- Confirmed Rails 6.0 support.
- Added ability to have custom real-time index processors (which handles all indices) and populators (which handles a particular index). These are available to get/set via
ThinkingSphinx::RealTime.processorandThinkingSphinx::RealTime.populator(and discussed in more detail in the release notes).
- Improve failure message when tables don't exist for models associated with Sphinx indices (Kiril Mitov in #1139).
- Injected has-many/habtm collection search calls as default extensions to associations in Rails 5+, as it's a more reliable approach in Rails 6.0.0.
- Reverted loading change behaviour from v4.3.1 for Rails v5 (Eduardo J. in #1138).
- Fixed loading of index files to work with Rails 6 and Zeitwerk (#1137).
- Allow overriding of Sphinx's running state, which is useful when Sphinx commands are interacting with a remote Sphinx daemon. As per discussions in #1131.
- Allow skipping of directory creation, as per discussions in #1131.
- Use ActiveSupport's lock monitor where possible (Rails 5.1.5 onwards) to avoid database deadlocks. Essential investigation by Jonathan del Strother (#1132).
- Allow facet searching on distributed indices (#1135).
- Allow changing the default encoding for MySQL database connections from utf8 to something else via the
mysql_encodingsetting inconfig/thinking_sphinx.yml. In the next significant release, the default will change to utf8mb4 (which is supported in MySQL 5.5.3 and newer). - Added Rails 6.0 and Manticore 2.8 to the test matrix.
- Use Arel's SQL literals for generated order clauses, to avoid warnings from Rails 6.
- Fix usage of alternative primary keys in update and deletion callbacks and attribute access.
- Ensure
respond_to?takes Sphinx scopes into account (Jonathan del Strother in #1124). - Add
:excerptsas a known option for search requests. - Fix depolymorphed association join construction with Rails 6.0.0.beta2.
- Reset ThinkingSphinx::Configuration's cached values when Rails reloads, to avoid holding onto stale references to ActiveRecord models (#1125).
- Don't join against associations in
sql_queryif they're only used by query-sourced properties (Hans de Graaff in #1127).
- The
:sqlsearch option can now accept per-model settings with model names as keys. e.g.ThinkingSphinx.search "foo", :sql => {'Article' => {:include => :user}}(Sergey Malykh in #1120).
- Drop MRI 2.2 from the test matrix, and thus no longer officially supported (though the code will likely continue to work with 2.2 for a while).
- Added MRI 2.6, Sphinx 3.1 and Manticore 2.7 to the test matrix.
- Real-time indices now work with non-default integer primary keys (alongside UUIDs or other non-integer primary keys).

- :group option within :sql options in a search call is passed through to the underlying ActiveRecord relation (Siarhei Hanchuk).

- Indexes defined in app/indices in engines are now loaded (Antonio Tapiador del Dujo).
- Query errors are classified as such, instead of getting the base SphinxError.

- Allow custom strings for SQL joins in index definitions.

- An index can have multiple sources, by using define_source within the index definition.
- sanitize_sql is available within an index definition.
- Providing :prefixes => true or :infixes => true as an option when declaring a field means just the noted fields have infixes/prefixes applied.
- ThinkingSphinx::Search#query_time returns the time Sphinx took to make the query.
- Namespaced model support.
- Default settings for index definition arguments can be set in config/thinking_sphinx.yml.
- A custom Riddle/Sphinx controller can be supplied. Useful for Flying Sphinx to have an API layer over Sphinx commands, without needing custom gems for different Thinking Sphinx/Flying Sphinx combinations.
- Correctly escape nulls in inheritance column (Darcy Laycock).
- Use ThinkingSphinx::Configuration#render_to_file instead of ThinkingSphinx::Configuration#build in test helpers (Darcy Laycock).
- Suppressing delta output in test helpers now works (Darcy Laycock).
First pre-release of v3. Not quite feature complete, but the important stuff is certainly covered. See the README for more the finer details.
