perf: release failed high-density route searches by ShiboSoftwareDev · Pull Request #2894 · tscircuit/tscircuit-autorouter

ShiboSoftwareDev · 2026-10-06T20:57:38Z

Summary

Failed high-density route searches were kept in memory even when detailed search-history capture was disabled.

This releases each failed search after preserving its error. When captureSearchDebug is enabled, the search is still retained for the debugger. Core's production preview graphics are unchanged.

Benchmark

Seven fresh-process A/B runs on the real Dataset 18 sample 002 large node:

Benchmark This PR

Run benchmarks by commenting on this PR:

/benchmark [benchmark.sh args...]
/benchmark-long [benchmark.sh args...]
/benchmark-effort
/benchmark-all [benchmark.sh args except --dataset]
/benchmark --same-machine
/benchmark-all --same-machine
/profile --dataset 18

Comment /benchmark to compare the PR base and head sequentially on the same 8-vCPU Blacksmith runner using the default dataset, or append any arguments accepted by ./benchmark.sh. Same-machine comparison is enabled by default, except for --pipeline 9net, which uses its dedicated cold/hot benchmark workflow.
Comment /benchmark-effort to compare 1x, 1.5x, and 2x effort on dataset18, including matched-sample via counts and scaled timeouts.
Comment /benchmark-long for an 8-vCPU run that defaults to 8 workers and has an eight-hour timeout.
Every benchmark runs each sample in a fresh process and reports Memory P50, P80, and P90.
Comment /benchmark-all to start separate workflow runs and result comments for dataset01 and dataset18. You may append benchmark arguments such as --pipeline 9; --dataset is not accepted because the command selects both datasets.
Append --same-machine to /benchmark-long or /benchmark-all to compare the PR base and head sequentially on the same 8-vCPU Blacksmith runner.
Comment /profile --dataset 18 to compare direct Pipeline 7 stage-time percentages between current main and the PR head sequentially on one Blacksmith runner.

Everything after /benchmark, /benchmark-long, or /benchmark-all is safely forwarded to ./benchmark.sh, except --profile-solvers, which enables profile comparison tables, and --same-machine, which enables the paired runner.
Examples: /benchmark --dataset 18 --sample-timeout 2000s, /benchmark --pipeline 10 --dataset 29, /benchmark --pipeline 10 --dataset 29 --sample 1, /benchmark --pipeline 7 --limit 20, /benchmark all 20 --concurrency 8, /benchmark --same-machine, /benchmark-all --pipeline 9 --same-machine, /benchmark-long --dataset 18, and /benchmark-long --same-machine --pipeline 9 --dataset 24 --sample-numbers 21 --sample-timeout 240s --concurrency 1.

Use /update-snapshots (or /us) to run BUN_UPDATE_SNAPSHOTS=1 bun test --timeout 120_000 on the PR branch and auto-commit snapshot updates.
Use /usf to read recent failed test files, update and verify their exact CI test shards, and auto-commit only their snapshots. It uses the configured fast benchmark runner by default; use /usf --ubuntu-latest for GitHub-hosted x64 CI parity.

Any PR whose title contains [BENCHMARK TEST] will automatically run one default-dataset benchmark on PR updates; it does not post a PR result comment.

Outcome changes: 0 improved, 0 regressed. DRC issues are totaled across solved samples. Timing percentiles include all samples, with failed and timed-out samples counted at their configured timeout; negative timing deltas are faster. Historical failures without timeout metadata make timing percentiles unavailable.
Style errors are averaged per completed sample with recorded lint counts for that type; historical/unlinted results are n/a. Angled traces counts violating segments.

Outcome changes: 0 improved, 1 regressed. DRC issues are totaled across solved samples. Timing percentiles include all samples, with failed and timed-out samples counted at their configured timeout; negative timing deltas are faster. Historical failures without timeout metadata make timing percentiles unavailable.
Style errors are averaged per completed sample with recorded lint counts for that type; historical/unlinted results are n/a. Angled traces counts violating segments.
