Adds go-parser/, a Go reimplementation of the xlsxread parser, verified
byte-for-byte against the Rust original before any cutover.
Reader fidelity is exact across all 299 input files: the canonical cell dump
of every sheet matches calamine's, locked in as a test against a committed
hash oracle. Reaching that required replacing extrame/xls, which corrupted
69% of cells and dropped a further 28% on the BIFF corpus, with pbnjay/grate;
correcting excelize's number-format application and trailing-cell trimming;
restoring carriage returns that XML line-ending normalisation strips from
2,233 ten_cum_thi values; and gating numeric re-rendering on cell type so
shared strings that merely look numeric keep their leading zeros.
The differential gate compares both parsers over all four datasets:
3,265,641 rows with identical full-table SHA-256, identical per-column
non-NULL counts, identical schema metadata and identical stdout.
Config moves from TOML to YAML for both parsers, so they keep reading the
same files and the gate stays meaningful. Verified by rebuilding 2016 and
2017-old2 with Rust under the new configs and matching the recorded counts.
build-db.js now refuses to publish a database whose row count does not match
the known figure, closing a path where an under-producing parser could ship a
truncated public dataset with green CI. The deploy workflow gains a
pull_request trigger and guards deploy to main, so branch verification can no
longer publish to production.
The repo held two near-duplicate projects. 2016/ and 2017/ each carried their
own React frontend, their own copy of the same Rust crate, and their own
package manager setup. 2016/tools/sync-from-thptqg2017.sh existed purely to
copy the parser source between them.
New layout:
index.html + src/ the 2017 frontend, now the only one
data/<id>/ 2016, 2017, 2017-old, 2017-old2
parser/ the single Rust crate, configs renamed to <id>.toml
docs/ both projects' docs, 2016 copies suffixed -2016-legacy
pending the merge pass
<id> is now one identifier end to end: data/<id>/ feeds parser/configs/<id>.toml
and produces db/<id>.db.gz.
pnpm gives way to npm. pnpm-workspace.yaml existed only to whitelist
better-sqlite3's native build, which npm permits by default, so it has no
equivalent and is simply gone. Lockfiles cannot be converted; package-lock.json
is generated fresh. The migration direction is safe — pnpm's strict layout
forbids phantom dependencies, so anything that resolved under pnpm resolves
under npm's flat tree.
Adds parser/scripts/build-db.js and src/datasets.js: the four dataset IDs are
declared once and read by both the build tooling and (from the next phase) the
frontend.
Follow-on fixes the move made necessary:
- eslint's Node-globals override pointed at scripts/, now parser/scripts/
- crawl-baotintuc.js wrote to <root>/data, now data/2017
- golden tests loaded configs by their old thptqg*-data.toml names
Drops the #[ignore]d Rust-vs-Node golden test. It shelled out to pnpm to run
scripts/build-database.js, a file removed when the parser was ported to Rust,
so it could never pass. check-duplicates.js and diff-datasets.js were already
broken before this change and are annotated as such rather than half-fixed.
63 Rust tests pass and clippy is clean from the new location.
