tsb-perf-evolve — Series.sortValues vs pandas Series.sort_values

🤖 This PR is maintained by Autoloop. Each accepted iteration adds a commit to this branch.

Program goal: Minimize fitness = tsb_mean_ms / pandas_mean_ms on a 100k-element numeric sort benchmark. Lower is better; < 1.0 means tsb beats pandas.

Current best metric: 21.048 (fitness from c029, tsb≈112ms / pandas≈5.3ms)

Program issue: #189

State file: tsb-perf-evolve.md

Iteration 30 — Pre-compute all 8 radix histograms in one scan

Change: Replace 8 per-pass count loops (each reading all n elements) with a single O(n) pre-scan that fills all 8×256 histogram buckets. Saves 7×n element reads from the histogram accumulation phase.

Parent: c029 (island 3, AoS scatter layout, fitness=21.048)
Operator: exploitation

Generated by Autoloop · ● 5.2M · ◷

Replace 8 per-pass count loops (each reading n elements) with a single O(n) pre-scan that fills all 8×256 histogram buckets at once. Each element's lo and hi key words are read once and all 8 byte extractions are done in the same iteration, saving 7×n element reads from the count phases. The 8 scatter passes are unchanged; only the histogram accumulation is collapsed into one loop.

Evergreen fix: Resolved merge conflict by merging main into this branch.

The conflicts were add/add conflicts in hash_pandas_object files (both branches added the same feature). Resolved by taking main's lint-fixed versions (which use const instead of let, avoid parameter reassignment, and use type imports).

Issue: Add/add conflict on src/stats/hash_pandas_object.ts, tests/stats/hash_pandas_object.test.ts, and playground/hash_pandas_object.html — both main and this branch added the same files independently, with minor style differences (import order, variable naming, ?? vs ! non-null assertion).

Resolution: Merged main into the PR branch and kept main's version of the conflicting files, which contains the more refined code (strict TS compliance: bytes[i] ?? 0 instead of bytes[i]!, better variable scoping).

I resolved the merge_conflict by merging origin/main into this branch.

Evergreen resolved a merge conflict on this PR.

What happened

main had added hash_pandas_object (the same feature this PR was building on) causing add/add conflicts in three files:

src/stats/hash_pandas_object.ts
tests/stats/hash_pandas_object.test.ts
playground/hash_pandas_object.html

Resolution

The conflicts were purely stylistic (same logic, minor formatting diffs: import type, variable naming, line wrapping). Resolved by taking main's version, which uses cleaner TypeScript style (import type, avoids parameter mutation, Biome-consistent formatting).

The merge commit is 9413c46.

Evergreen resolved the merge conflict on this PR.

Issue: Add/add conflicts in src/stats/hash_pandas_object.ts, tests/stats/hash_pandas_object.test.ts, and playground/hash_pandas_object.html — both main and the PR branch had added these files.

Resolution:

Used the PR branch's versions of the TypeScript source and test files (preserving the Autoloop iteration's changes).
Used main's version of playground/hash_pandas_object.html because the PR's version failed 7 playground conformance tests (missing required CSS variables, loading overlay, and playground block structure).
Brought in new benchmark files from main (bench_compare, bench_update, bench_xs).

Verification: All 1162 playground conformance tests pass. Test baseline is consistent with main (132 pre-existing failures unchanged).

Evergreen: merge conflict resolved ✅

Merged main into autoloop/tsb-perf-evolve. There were add/add conflicts in:

src/stats/hash_pandas_object.ts
tests/stats/hash_pandas_object.test.ts

Both conflicts were cosmetic style differences (type imports, local variable instead of parameter mutation, ?? 0 guard). Resolved by adopting main's cleaner versions — no behavioral change.

Evergreen: Merge Conflict Resolved ✅

Merged main into autoloop/tsb-perf-evolve and resolved two add/add conflicts in:

src/stats/hash_pandas_object.ts — resolved import ordering and minor code style differences (local variable h vs mutating hash parameter; bytes[i] ?? 0 vs bytes[i]!)
tests/stats/hash_pandas_object.test.ts — resolved formatting of a fc.property call

Both sides had identical logic; main's cleaner style was used for the resolved version. The PR branch is now up to date with main.

Evergreen: Resolved merge conflict between autoloop/tsb-perf-evolve and main.

Conflict: src/stats/hash_pandas_object.ts and tests/stats/hash_pandas_object.test.ts had add/add conflicts — both branches added the same file independently.

Resolution: Took main's style improvements (type-only imports for DataFrame/Scalar, local h variables instead of parameter mutation, ?? over ! for array access, and formatted multi-line fc.property call) since these are cosmetic differences with no functional impact on the PR's perf features.

Evergreen: Merge conflict resolved ✅

Merged main into autoloop/tsb-perf-evolve. The conflict was an add/add on src/stats/hash_pandas_object.ts and tests/stats/hash_pandas_object.test.ts — both branches had added the same file. Resolved by taking main's version, which includes the lint fixes (useImportType, noParameterAssign, formatting) from PR #263/main.

Evergreen: Resolved merge conflict with main.

Two files had add/add conflicts in src/stats/hash_pandas_object.ts and tests/stats/hash_pandas_object.test.ts. Both sides added the same feature; the conflicts were formatting/style differences. Resolved by taking main's style improvements:

Used local variable h in fnvString/fnvScalar instead of mutating the parameter
Used bytes[i] ?? 0 instead of bytes[i]! (no non-null assertion)
Used import type { DataFrame } (type-only import, correct since instanceof only checks Series)
Reformatted long function signatures to single-line form

The merge commit has been pushed.

Evergreen resolved a merge conflict on this PR.

Two add/add conflicts were present in src/stats/hash_pandas_object.ts and tests/stats/hash_pandas_object.test.ts (both introduced on main and the PR branch at the same time). The conflicts were purely stylistic — main's version uses cleaner local variable scoping (let h = hash instead of mutating the parameter) and proper import type for type-only imports. main's version was used for both files.

Evergreen: Merge Conflict Resolved ✅

Both main and this PR added src/stats/hash_pandas_object.ts (the hashPandasObject feature). The conflict was purely an add/add — the implementations were functionally identical with only minor style differences (variable naming, import type usage, line formatting).

Resolution: Accepted main's version, which is already merged, reviewed, and uses cleaner TypeScript patterns (import type, local h variables, ?? 0 safety).

The branch has been updated with a merge commit.

Resolved conflicts (commits 7380f1b and 5c20b6f):

Ran biome auto-fix across src/stats/hash_pandas_object.ts, src/core/series.ts, and tests/stats/hash_pandas_object.test.ts to fix formatting, import type, and import ordering
Fixed 7 noParameterAssign errors in fnvString and fnvScalar by using local variables instead of mutating function parameters
Replaced bytes[i]! non-null assertion with DataView.getUint8(i) which always returns a number
All 6798 tests pass, lint is clean (0 errors), and typecheck passes
