vanilla, the V HTTP/1.1 server, as a framework entry routed by http1_1.router: each route is a match over the path segments. It subscribes to the HTTP/1.1 profiles vanilla-epoll serves, with /json serialized and gzip-compressed per request (libdeflate, level 1) and no response caches. app.v is shared byte for byte with vanilla-veb_like. V 5516000 with its vc snapshot, vanilla fb4c7e7. validate.sh: 79 passed. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

Per review: flagship is reserved for a language's reference framework (aspnet for C#, actix for Rust). vanilla runs production services but is young and has no ecosystem, which is what emerging describes. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

Description
Adds
vanilla-router: vanilla, a multi-threaded HTTP/1.1 server written in V, as a framework entry using its explicit router,http1_1.router.type: emerging,mode: tuned.#1542 adds
vanilla-veb_like, the same app with vanilla's declarative router. The two entries shareapp.vbyte for byte, so the leaderboard compares the two routing styles on identical handlers.Routing
Each route is a
matchover the request's path segments.router.methodreads the method androuter.pathreturns a zero-copy cursor over the path:Every route goes through the router, on both listeners. There is no fast path ahead of it. A known path under the wrong method gets 405 with
Allow. A request whoseConnectionheader listsclosegets its response, then the connection closes, on the synchronous and the parked routes alike.Profiles
The full HTTP/1.1 set:
What each route does:
/json/{count}is serialized per request from the dataset's fields. WhenAccept-Encodingaccepts gzip, it is compressed per request with libdeflate, at level 1. On the 50-item body, level 1 takes 15 µs for 1708 bytes and level 6 takes 38 µs for 1478 bytes. Compression is most of the request, and json-comp scores rps × ratio², so level 1 comes out ahead. Brotli is slower at every size on these 4 to 8 KB bodies.pg_async, until the reply arrives. Each worker has its own pipelined pool, sized fromDATABASE_MAX_CONN. fortunes adds the runtime row, sorts, and renders the page by hand per request, every message HTML-escaped./delay/{ms}parks on a one-shot timerfd from a per-worker free-list./static/*goes through vanilla'sstatic_assets. It picks the.br/.gzsibling perAccept-Encodingand re-checks each file against the disk (onestatper 100 ms). Bodies of 16 KiB or more go out withsendfile(2), over kTLS on:8081.:8081is TLS 1.3 with ALPNhttp/1.1through Mbed TLS 4, built as invanilla-epoll.Unlike the
vanilla-epollengine entry, nothing is cached and nothing is pre-serialized. There is no gzip response cache, no JSON prefixes, and no skip-parse path for/pipeline.Type, mode, completeness
type: emerging. vanilla runs production services, but it is young and has no ecosystem. These entries were first filed as flagship; flagship is for a language's reference framework (see the discussion in Add vanilla-veb_like (vanilla with its declarative router; emerging, tuned) #1542).mode: tuned. The JSON and HTML are written by hand, compression uses libdeflate, and the build uses-gc none. vanilla has no JSON serializer, template engine or compression middleware of its own, so Standard's per-profile rules can't be met as written.completeness: all four axes are declaredfalse.vanilla-veb_likedeclaresrouting: true.Build
