Reviewer's GuideThis PR performs the September 2026 benchmark refresh by upgrading all active parser integrations, adapting sqlite3-parser’s new arena API, expanding historical coverage to 95 releases, removing the unsupported orql family with stale-row protection in export, and regenerating the documentation, metadata, history, badges, and benchmark site data from the completed run.

When export is run after pulling this change without rerunning both batch producers, the existing target/batch_dist/summary.csv and target/batch_mem_dist/summary.csv can still contain orql. Only the per-statement summary is filtered here; read_batch_perf() and read_batch_mem() remain unfiltered, and batch_for() therefore serializes the removed parser into each dialect's batch array even though it is absent from the bundle's parser list. Apply the same known filter to both batch row sets so stale artifacts cannot produce an internally inconsistent snapshot.
Useful? React with 👍 / 👎.

Fixed in 53d972e. The filter is now retain_known, applied to the per-statement and both batch summaries, with a unit test pinning that rows for parsers no longer compiled in are dropped.

In `@README.md`:
- Line 19: Update the speed-range wording in the paragraph so “6-to-9
microsecond band” uses words instead of ASCII dash punctuation, while preserving
the meaning and all other prose unchanged.
In `@timemachine/src/families/polyglot.rs`:
- Around line 121-126: Replace the public Parser::try_parse Result error type
from String with a shared error enum deriving thiserror::Error. Update all
implementations and adapter macros, including the registrations in polyglot.rs,
qusql.rs, sqlglot.rs, sqlparser.rs, and turso.rs, to construct and propagate the
shared enum while preserving existing parse behavior.
In `@timemachine/src/families/sqlite3.rs`:
- Line 8: Rewrite the comments at timemachine/src/families/sqlite3.rs lines 8-8
and timemachine/src/registry.rs lines 146-147 to remove the ASCII hyphenated
terms caller-owned and bare-statement, while preserving their meaning and

- Around line 179-186: Update the sqlite3_version! macro expansion used for
Sqlite3V0_17 so the generated public type receives version-specific rustdoc.

Quarterly parser refresh. Every benchmarked parser moves to its latest release,
sqlparser-rs0.63,polyglot-sql0.11,qusql-parse0.11,sqlglot-rust0.10.29,sqlite3-parser0.17 (which now parses into a caller-ownedbumpaloarena, so the adapters hand it a fresh arena per parse),turso_parser0.7.2 andpg_query.rs6.2.0. The time machine gains twelve release points and now ends at current code with 95 versions across 7 pure-Rust families, and the entire benchmark ran end to end, so every snapshot, badge, failure list and trend on the site comes from this September data.orqlis removed. Its upstream has gone quiet, the workspace no longer builds on stable rustc, and a reported defect there has sat unaddressed, so keeping it would freeze a dead parser into every chart. Oracle remains a benchmarked dialect, covered by the multi-dialect parsers. The exporter now also drops perf rows for parsers that are no longer compiled in, so leftovers from an older run can never leak into a snapshot.The abstract states the numbers this run actually produced, permissive parsers and their false-positive rates, the new speed spread with
polyglot-sqlback inside the pack, and each parser card carries repository metadata re-verified from live sources, including thattursofuzzes now andpolyglotnever did.Summary by Sourcery
Refresh the parser benchmark suite and published September 2026 results while removing the defunct orql integration.
New Features:
Bug Fixes:
Enhancements:
Build:
CI:
Documentation:
Tests:
Benchmark data was stale because parser releases and repository metadata were outdated. The refresh updates supported parser versions, adds twelve historical release points, and removes inactive
orqlcoverage while retaining Oracle support through multi dialect parsers.The
sqlite3-parseradapters now use a caller ownedbumpaloarena for each parse. The exporter also ignores stale performance rows for parsers that are not compiled in. September 2026 benchmark artifacts and descriptive metrics were regenerated.
