From 325106920f2e2effeeb3a90a55f3cfc733cad835 Mon Sep 17 00:00:00 2001 From: Joseph Doherty Date: Sun, 24 May 2026 04:50:09 -0400 Subject: [PATCH] Rust client: port BenchReadBulk subcommand + session.rs tightening MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The bulk-write/read SDK methods (read_bulk, write_bulk, write2_bulk, write_secured_bulk, write_secured2_bulk) and the matching clap subcommands (ReadBulk, WriteBulk, Write2Bulk, WriteSecuredBulk, WriteSecured2Bulk) were already on HEAD from a prior session — they were the only bulk family that HEAD shipped before the .NET / Go / Python / Java parallel ports. The one missing piece from the divergent branch (commit f220908) was the BenchReadBulk benchmark harness. mxgw-cli/src/main.rs adds: - BenchReadBulk clap variant with flags --client-name, --duration-seconds, --warmup-seconds, --bulk-size, --tag-start, --tag-prefix, --tag-attribute, --timeout-ms, --json — defaults match the .NET and Go benches. - run_bench_read_bulk(): open-session → register → subscribe_bulk on the synthesized TestMachine_NNN.TestChangingInt tags to populate the worker value cache → warmup → steady-state loop with per-call std::time::Instant capture → unsubscribe → close-session. - BenchStats + LatencySummary structs and a percentile() helper (nearest-rank with linear interpolation, matching the Go and .NET implementations) so the cross-language JSON output is byte-for- byte comparable. JSON schema: language / command / endpoint / clientName / bulkSize / durationSeconds / warmupSeconds / durationMs / tags / totalCalls / successfulCalls / failedCalls / totalReadResults / cachedReadResults / callsPerSecond / latencyMs:{p50,p95,p99,max,mean}. scripts/bench-read-bulk.ps1 will pick up the Rust line on its next run. session.rs picks up minor tightening tied to the bulk SDK methods that were already in the file (per-entry validation paths, BulkReplyKind dispatch coverage) — no public-surface change. Verification: cargo build --workspace clean (the 2 pre-existing options.rs missing_docs warnings remain — out of scope); cargo test --workspace 34/34 passing; cargo clippy --workspace --all-targets has only the 3 pre-existing tolerated warnings (enum_variant_names on BulkReplyKind, missing_docs on options.rs, clone_on_copy on galaxy.rs:282). Manual smoke against live gateway on localhost:5120: read-bulk on two TestMachine tags returned wasCached=true, wasSuccessful=true; bench-read-bulk --duration-seconds 2 --warmup-seconds 1 --bulk-size 2 --json ran 363 calls / 181.35 calls per second / p50=5.3 ms / p99=7.8 ms / 726 of 726 cached reads, all emitting valid JSON in the shared bench schema.
