Varve.Protocol.Client

The HTTP client for a Varve server, and what a server needs to reach other servers: SERVICE over HTTP for the evaluator, and the document fetch that LOAD needs, both under an endpoint policy the operator sets.

  • SparqlHttpClient talks to one dataset's endpoints: queries and updates (SPARQL 1.1 Protocol), the Graph Store Protocol, the change feed and the diff, and the dataset's management resources under /manage/ (with a token for the management audience), with If-Match, Varve-As-Of and Accept as the caller says. Its bearer token comes from a BearerTokenProvider called for every request, so one client serves many users; a token past its expiry is never sent (ADR 0127).
  • FollowAsync follows the commits: history in pages, then the live tail, each commit to a handler and then its position to an IFollowCheckpoint: at least once, resumable from any position (ADR 0129). The records are Varve.Delta's, so a consumer of the feed ships no store (ADR 0128).
  • ApplyAsync makes a dataset's data what a DatasetSetup declares: its baseline by the Graph Store Protocol and its migrations, on a dataset the management plane declares (ADR 0163), each recorded in varve:setup in its own commit; applying it again commits nothing (ADR 0130). DatasetSetupFile reads one from the setup file's YAML subset.
  • AddVarve (Varve.Protocol.Client.Hosting) registers the client in an application's services and applies its setup as the host starts, failing the start when it cannot (ADR 0131).
  • HttpServiceHandler implements the evaluator's IServiceHandler: the SERVICE pattern is sent as SELECT … WHERE { … }, the answer read back with Varve.Sparql.Results. A failure is returned, and SILENT is the evaluator's decision (ADR 0055).
  • RdfDocumentClient fetches an RDF document by IRI with content negotiation over the four syntaxes. A host binds ILoadSource to it.
  • EndpointPolicy decides every outbound address before a connection is opened: an allow-list of IRI prefixes, empty by default; http and https only; loopback, link-local and private addresses refused unless allowed; no redirects, no credentials in the authority.
  • ClientLimits bound every request: a timeout and a cap on response bytes.
EndpointPolicy policy = new(["https://query.wikidata.org/"], allowPrivateAddresses: false);
HttpClient http = OutboundHttp.CreateClient();
EvaluationOptions options = new() { ServiceHandler = new HttpServiceHandler(http, policy, ClientLimits.Default) };

ADRs 0103, 0104 and 0127–0131.
