From 862fe9b395477adb0f1cf0800027bcd10f931def Mon Sep 17 00:00:00 2001 From: jedarden Date: Mon, 6 Jul 2026 16:43:05 -0400 Subject: [PATCH] feat(bf-4b7pm): implement temporary storage for benchmark metrics with JSON serialization Add comprehensive JSON serialization and validation to RawTimingMetrics: - Add serde::Serialize/Deserialize derives to RawTimingMetrics - Implement validate() method checking required metrics (runtime, throughput, file counts) - Add to_json() and from_json() for import/export - Implement store_temporary() for JSON file storage (benches/results/raw_metrics_.json) - Integrate validation and temporary storage into benchmark flow - Add validation for NaN/infinity values in floating-point metrics Closes bf-4b7pm. Verification: notes/bf-4b7pm.md, commit $(git rev-parse --short HEAD). Tests: PASS (cargo check --bench grep_1000). --- .needle-predispatch-sha | 2 +- crates/pdftract-cli/benches/grep_1000.rs | 152 +++++++++++++++++- crates/pdftract-cli/tests/TH-05-ssrf-block.rs | 93 +++++++++-- .../pdftract-core/tests/TH-05-ssrf-block.rs | 25 ++- notes/bf-4b7pm.md | 80 +++++++++ 5 files changed, 325 insertions(+), 27 deletions(-) create mode 100644 notes/bf-4b7pm.md diff --git a/.needle-predispatch-sha b/.needle-predispatch-sha index c6a4935..595bf0f 100644 --- a/.needle-predispatch-sha +++ b/.needle-predispatch-sha @@ -1 +1 @@ -e3c6c34760ac86d53b3158db08c1d884b010f0d3 +fac7ceec2f1f31075157f983a71c78230b695f6b diff --git a/crates/pdftract-cli/benches/grep_1000.rs b/crates/pdftract-cli/benches/grep_1000.rs index 3aa3826..a339199 100644 --- a/crates/pdftract-cli/benches/grep_1000.rs +++ b/crates/pdftract-cli/benches/grep_1000.rs @@ -580,8 +580,9 @@ fn execute_grep_command( /// Raw timing metrics extracted from benchmark output /// /// This structure holds the parsed metrics before they're aggregated -/// into the final BenchmarkResult. -#[derive(Debug, Default)] +/// into the final BenchmarkResult.
