From 821fd47c52449f4e1c7398dd2823f52dcdf92ff1 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Martynas=20Jusevi=C4=8Dius?= Date: Wed, 18 Feb 2026 17:03:07 +0100 Subject: [PATCH 1/5] Introduce `ServiceContext` to decouple HTTP infrastructure from `Service` MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit `Service` is now a pure data interface (SPARQL endpoint URLs + credentials only), no longer extending `RemoteService`. HTTP client/proxy infrastructure is moved into the new `ServiceContext` class, which pairs a `Service` with its `Client`, `MediaTypes`, `maxGetRequestSize`, and backend proxy URI. - `lapp:frontendProxy` and `lapp:backendProxy` removed from RDF model; loaded from system-level config (`LDHC.frontendProxy`, `LDHC.backendProxy`) at startup and stored in a `serviceContextMap` in `Application` - `Application.getServiceContext(Service)` looks up the `ServiceContext` for any `Service` at runtime - All JAX-RS resources and filters obtain client/proxy access via `getSystem().getServiceContext(service).getX()` - Import chain (`ImportExecutor`, `CSVGraphStore*`, `RDFGraphStoreOutput`, `StreamRDFOutputWriter`) receives `Service + Application system` (not `ServiceContext`) since they are plain Java objects, not HK2-managed beans - `Application.ban(Resource, ...)` overload removed; all callers use the `ban(URI, ...)` form - `core.model.Application.getService()` removed to avoid covariant return type clash after `ldh.Service` dropped `RemoteService` šŸ¤– Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- config/system.trig | 14 +- docker-compose.yml | 3 + http-tests/config/system.trig | 24 +- platform/context.xsl | 12 + platform/entrypoint.sh | 15 + .../atomgraph/linkeddatahub/Application.java | 106 ++++++- .../linkeddatahub/apps/model/Application.java | 10 +- .../apps/model/impl/ApplicationImpl.java | 6 - .../linkeddatahub/imports/ImportExecutor.java | 110 +++---- .../imports/stream/RDFGraphStoreOutput.java | 94 +++--- .../imports/stream/StreamRDFOutputWriter.java | 51 ++-- .../stream/csv/CSVGraphStoreOutput.java | 47 +-- .../stream/csv/CSVGraphStoreOutputWriter.java | 51 ++-- .../stream/csv/CSVGraphStoreRowProcessor.java | 85 +++--- .../linkeddatahub/model/Service.java | 51 ++-- .../linkeddatahub/model/ServiceContext.java | 276 ++++++++++++++++++ .../linkeddatahub/model/impl/ServiceImpl.java | 201 +------------ .../model/impl/ServiceImplementation.java | 60 +--- .../linkeddatahub/resource/Generate.java | 2 +- .../linkeddatahub/resource/Namespace.java | 2 +- .../linkeddatahub/resource/acl/Access.java | 20 +- .../resource/acl/AccessRequest.java | 20 +- .../resource/admin/ClearOntology.java | 39 +-- .../linkeddatahub/resource/admin/SignUp.java | 15 +- .../resource/admin/pkg/InstallPackage.java | 8 +- .../resource/admin/pkg/UninstallPackage.java | 8 +- .../resource/oauth2/LoginBase.java | 32 +- .../linkeddatahub/resource/upload/Item.java | 2 +- .../filter/request/AuthenticationFilter.java | 5 +- .../filter/request/AuthorizationFilter.java | 10 +- .../server/filter/request/OntologyFilter.java | 2 +- .../response/CacheInvalidationFilter.java | 59 ++-- .../filter/response/ProvenanceFilter.java | 3 +- .../model/impl/DirectGraphStoreImpl.java | 20 +- .../server/model/impl/SPARQLEndpointImpl.java | 12 +- .../server/util/OntologyModelGetter.java | 23 +- .../linkeddatahub/vocabulary/LDHC.java | 9 + 37 files changed, 878 insertions(+), 629 deletions(-) create mode 100644 src/main/java/com/atomgraph/linkeddatahub/model/ServiceContext.java diff --git a/config/system.trig b/config/system.trig index fd2a61b8f..5117cc28e 100644 --- a/config/system.trig +++ b/config/system.trig @@ -23,8 +23,7 @@ lapp:origin ;
