Subject: [PATCH 003/106] Use 'Goo.main_languages' to get a property value. now
 when retrieving a value only the object with a language included in
 main_languages will be taken (value with no lang defined are taken too). Be
 careful if an ontology contains several prefLabel with lang defined here

+ ;  Striping setup
+ ;
+ ;  These parameters have only effect when Striping is set to 1 in the
+ ;  [Database] section, in which case the DatabaseFile parameter is ignored.
+ ;
+ ;  With striping, the database is spawned across multiple segments
+ ;  where each segment can have multiple stripes.
+ ;
+ ;  Format of the lines below:
+ ;    Segment<number> = <size>, <stripe file name> [, <stripe file name> .. ]
+ ;
+ ;  <number> must be ordered from 1 up.
+ ;
+ ;  The <size> is the total size of the segment which is equally divided
+ ;  across all stripes forming  the segment. Its specification can be in
+ ;  gigabytes (g), megabytes (m), kilobytes (k) or in database blocks
+ ;  (b, the default)
+ ;
+ ;  Note that the segment size must be a multiple of the database page size
+ ;  which is currently 8k. Also, the segment size must be divisible by the
+ ;  number of stripe files forming  the segment.
+ ;
+ ;  The example below creates a 200 meg database striped on two segments
+ ;  with two stripes of 50 meg and one of 100 meg.
+ ;
+ ;  You can always add more segments to the configuration, but once
+ ;  added, do not change the setup.

Subject: [PATCH 060/106] Feature: Enhance SOLR integration and add a Schema
 API (#54)

* add an abstraction to SOLR integeration and add Schema API

* add SOLR  Schema API tests

* update SOLR backend configuration and init

* use the new Solr connector in the model search interface

* update search test to cover the new automatic indexing and unindexing

* handle the solr container initialization when running docker for tests

* add  omit_norms options for SolrSchemaGenerator

* fix solr schema initial dynamic fields declaration and replace the usage of   mapping-ISOLatin1Accent

* delay the schema generation to after model declarations or in demand

* add solr edismax fitlers tests

* fix indexBatch and unindexBatch tests

* add security checks to the index and unindex functions

* change dynamic fields names to have less code migration

* update clear_all_schema to remove all copy and normal fields

* add an option to force solr initialization if wanted

* handle indexing embed objects of a model

* add index update option

* fix clear all schema to just remove all the fields and recreate them

* add index_enabled?  helper for models

* perform a status test  when initializing the solr connector

* extract init_search_connection function from init_search_connections

* fix typo in indexOptimize call

* add solr search using  HTTP post instead of GET for large queries

Subject: [PATCH 062/106] Fix: Invalidating cache after insertion of a new 
 element (#60)

* create a test to reproduce the cache invalidate on insert bug

* update sparql client to  version 3.2.0

* handle the case virtuoso insert data  bug

* use development branch of sparql-client

+ ;  Striping setup
+ ;
+ ;  These parameters have only effect when Striping is set to 1 in the
+ ;  [Database] section, in which case the DatabaseFile parameter is ignored.
+ ;
+ ;  With striping, the database is spawned across multiple segments
+ ;  where each segment can have multiple stripes.
+ ;
+ ;  Format of the lines below:
+ ;    Segment<number> = <size>, <stripe file name> [, <stripe file name> .. ]
+ ;
+ ;  <number> must be ordered from 1 up.
+ ;
+ ;  The <size> is the total size of the segment which is equally divided
+ ;  across all stripes forming  the segment. Its specification can be in
+ ;  gigabytes (g), megabytes (m), kilobytes (k) or in database blocks
+ ;  (b, the default)
+ ;
+ ;  Note that the segment size must be a multiple of the database page size
+ ;  which is currently 8k. Also, the segment size must be divisible by the
+ ;  number of stripe files forming  the segment.
+ ;
+ ;  The example below creates a 200 meg database striped on two segments
+ ;  with two stripes of 50 meg and one of 100 meg.
+ ;
+ ;  You can always add more segments to the configuration, but once
+ ;  added, do not change the setup.

 and logging config and tests (#67)

* handle the case were we don't use the indexation feature

* change ask to select for better compatibility with virtuoso

* update append triples function to catch errors and log them

* put the number of appended chunks to 50 000 line by chunck

* update chunks insert for virtuoso to be 50k lines instead of 500k to prevent crashing

* implement mode paginated_all that will get all the resources using pagination

* add query logging configuration and remove cube

* add logging test

 linux container tests

  - remove custom wait logic; rely on docker compose --wait healthchecks
  - add linux overrides to run unit tests in a container (useful on macOS)
  - add no-ports override for containerized runs
  - update compose mounts and move backend fixtures to test/fixtures
  - document docker test commands and env vars

+## Tests
+
+Run the unit tests:
+
+```
+bundle exec rake test
+```
+
+Run docker-backed tests (host Ruby):
+
+```
+bundle exec rake test:docker:fs
+bundle exec rake test:docker:ag
+bundle exec rake test:docker:vo
+bundle exec rake test:docker:gd
+```
+
+Run docker-backed tests inside the Linux container:
+
+```
+bundle exec rake test:docker:fs:linux
+bundle exec rake test:docker:ag:linux
+bundle exec rake test:docker:vo:linux
+bundle exec rake test:docker:gd:linux
+```
+
+Start a shell in the Linux test container (default backend `fs`):
+
+```
+bundle exec rake test:docker:shell
+bundle exec rake test:docker:shell[ag]
+```
+
+Set `OP_KEEP_CONTAINERS=1` to keep services up after tests or shell exit.
+Set `OP_TEST_DOCKER_BACKEND=ag` (or `fs`, `vo`, `gd`) to change the default backend for `test:docker:shell`, `test:docker:up`, and `test:docker:down`.

Subject: [PATCH 097/106]  test: centralize safety guard + move test_reset into
 test helper

  When adding rake tasks for running unit tests in linux containers,
  unit tests started failing due to unsafe target detection and state leakage.
  This refactor consolidates safety checks into TestSafety,
  moves test_reset into test helpers. It also adds a redis key-count guard to
  abort against non-test instances.

- ;  Striping setup
- ;
- ;  These parameters have only effect when Striping is set to 1 in the
- ;  [Database] section, in which case the DatabaseFile parameter is ignored.
- ;
- ;  With striping, the database is spawned across multiple segments
- ;  where each segment can have multiple stripes.
- ;
- ;  Format of the lines below:
- ;    Segment<number> = <size>, <stripe file name> [, <stripe file name> .. ]
- ;
- ;  <number> must be ordered from 1 up.
- ;
- ;  The <size> is the total size of the segment which is equally divided
- ;  across all stripes forming  the segment. Its specification can be in
- ;  gigabytes (g), megabytes (m), kilobytes (k) or in database blocks
- ;  (b, the default)
- ;
- ;  Note that the segment size must be a multiple of the database page size
- ;  which is currently 8k. Also, the segment size must be divisible by the
- ;  number of stripe files forming  the segment.
- ;
- ;  The example below creates a 200 meg database striped on two segments
- ;  with two stripes of 50 meg and one of 100 meg.
- ;
- ;  You can always add more segments to the configuration, but once
- ;  added, do not change the setup.
