Command + builder + worker for advanced-mode SQL CREATE TABLE
(sub-phase 4a), executed structurally through do_create_table:
- Command::SqlCreateTable + build_sql_create_table (ddl.rs): aliases via
from_sql_name (incl. double precision), column- and table-level
PRIMARY KEY, redundant-flag de-dup off a sole PK, IF NOT EXISTS.
Advanced REGISTRY entry on the shared `create` word (SQL-first, DSL
fallback); no-PK tables allowed (user-confirmed).
- Worker (db.rs): Request::SqlCreateTable + CreateOutcome + snapshot_then
(one undo step); IF NOT EXISTS no-op (no snapshot, but journalled, like
read-only commands). do_create_table inline-PK rule aligned with the
rebuild generator schema_to_ddl — no round-trip DDL drift; serial
autoincrement is independent of inline-PK (verified by round-trip
tests).
- Runtime/App: dispatch + CommandOutcome::SchemaSkipped +
AppEvent::DslCreateSkipped (structure + "already exists — skipped"
note). Friendly catalog keys added (engine-neutral).
DEFAULT/CHECK/table-level UNIQUE are absent from the 4a grammar (parse
error with usage skeleton; friendly message + support land in the 4a.2
constraint slice) — user-confirmed.
Tests: type resolver, grammar shape, builder (incl. the PK
detection bug they caught), and tests/sql_create_table.rs (worker
round-trip, serial autoincrement first/non-first across rebuild, IF NOT
EXISTS no-op + journalling, no-PK table, one undo step) + a replay-as-
write test. 1739 pass / 0 fail / 1 ignored; clippy clean.
Exit gate: ADR-0035 Proposed -> Accepted (validated end-to-end by 4a);
README + requirements.md Q1 updated.
/runda found silent data loss: with the non-fatal snapshot-failure
policy, a committed mutation whose snapshot couldn't be staged left
the redo stack stale (redo-clear was only a side effect of finalize),
so a later redo silently discarded the new work. Same gap in batches.
- SnapshotStore::clear_redo() drops the redo stack + payloads
- snapshot_then / end_batch call it when committed user work has no
staged snapshot; for disk-full it succeeds where a full backup
couldn't (tiny index write + payload deletes)
- unit test + integration regression (forced staging failure)
- ADR-0006 implementation note records the fix + residual edge
1698 passed / 0 failed / 1 ignored; clippy clean.
Three Tier-3 flows through the real worker:
- undo/redo steps back across interleaved DSL insert, SQL insert,
and SQL delete — proving SQL DML snapshots like DSL (R22)
- undo restores the database read model AND the on-disk CSV
together (consistent (db, csv) pair)
- the snapshot ring persists across a close + reopen of the project
(undo works in a later session)
1696 passed / 0 failed / 1 ignored; clippy clean.
The undo ring is local working state, handled at all three
project-file seams (R13):
- .gitignore template ignores /.snapshots/
- export excludes .snapshots/ (like playground.db / history.log)
- safely_delete_temp_project allowlists .snapshots/ so a temp that
was modified then undone back to empty stays auto-deletable
- undo::SNAPSHOTS_DIR is now a pub const referenced by all three
- tests: gitignore content, export exclusion, cleanup allowlist
1693 passed / 0 failed / 1 ignored; clippy clean.
- snapshot_then() brackets all 19 mutating dispatch arms: stage a
pre-op snapshot, finalise on success / discard on rollback; gated
on a user command source (internal ops like open-time rebuild are
not snapshotted) and on undo being enabled
- BatchState + BeginBatch/EndBatch requests: a batch takes one
boundary snapshot, suppresses per-command snapshots, and finalises
iff a mutation committed (one undo step per replay/batch)
- Undo/Redo/PeekUndo/PeekRedo requests handled in worker_loop with
&mut conn for the restore; cleanup() sweeps crash leftovers on open
- Database::{undo,redo,peek_undo,peek_redo,begin_batch,end_batch} +
open_with_persistence_and_undo(); snapshot failures are non-fatal
(logged), restore failures surface
- 6 Tier-3 integration tests through the real worker
1680 passed / 0 failed / 1 ignored; clippy clean.
Replay (§3): run_replay parses <ts>|<status>|<source> journal records — runs ok, skips non-ok — while still accepting bare .commands scripts (prefix-detected so a | inside a bare command isn't misread). Fixes replay history.log, which died on line 1.
Journal failures (§1/§2): failed commands are recorded err via a new Action::JournalFailure, emitted by the pure-sync App for both parse failures and worker-execution failures (runtime appends best-effort, never fatal). Hydration reads all records so typo'd/rejected commands are recallable across sessions.
Amendment 1 — replay filters app-lifecycle commands: a working replay history.log exposed that the journal also records save as/load/new/export/import/rebuild/mode (which would panic the worker dispatch or abort replay). Replay now re-applies only schema/data writes and skips every app-lifecycle command + nested replay, classified by entry word so modal/incomplete forms (save as, bare mode) and quit skip uniformly rather than aborting. All skips continue (reversing the nested-replay refusal); import and nested replay warn. replay.error_nested removed; replay.skipped_import/_replay added; ReplayCompleted carries warnings. requirements.md U3/U4 updated; app-command runtime-failure journalling tracked as a follow-up.
1659 passing / 0 failing / 0 skipped / 1 ignored. Clippy clean.
Wire `insert`/`update`/`delete` as shared DSL/SQL entry words through the
category-grouped dispatcher (ADR-0033 Amendment 1): the Advanced SQL nodes
move off the dev words (`sqlinsert`/`sql_update`/`sql_delete`) to the real
keywords, registered alongside the Simple DSL nodes. Remove the dev-word
scaffold; collapse build_sql_{insert,update,delete} to source.trim();
de-duplicate the two REGISTRY entry-word listing sites.
Dispatch model (ADR-0033 Amendment 3, written this round):
- A command is the mode-rooted grammar-path outcome; identity is intrinsic.
Advanced mode tries SQL first, falling back to the Simple DSL command when
no SQL branch matches a token (`delete … --all-rows` falls back;
`update … --all-rows` does not — the SET expression absorbs it, harmless
since the engine treats `--all-rows` as a comment).
- Simple mode commits the DSL candidate for a shared word, surfacing the real
DSL error; bare "this is SQL" is reserved for SQL-only entry words
(`select`/`with`). A content rejection on the SQL candidate (internal
table) is committed, never masked by the DSL fallback.
Combined DSL-error + advanced-SQL pointer (ADR-0033 Amendment 3): a Simple-mode
definite DSL error that would run as SQL in advanced mode gains the
`advanced_mode.also_valid_sql` suffix — in the live hint (ambient_hint_in_mode)
and on submit (dispatch_dsl), via the shared advanced_alternative_note — so the
actionable DSL fix and the mode pointer coexist (submit covers constructs that
surface only on submit, e.g. `delete … returning`).
Internal-table rejection symmetrised (/runda finding B, ADR-0030 §6): the DSL
data-command target slots (insert/update/delete/show data/show table) gained
reject_internal_table, so `__rdbms_*` tables are refused in Simple mode too —
previously only the advanced SQL grammar rejected them.
Mode-awareness: classify_input_with_schema_in_mode and
invalid_ident_at_cursor_in_mode stop leaking the advanced SQL view into
simple-mode hints for shared words.
Tests: dev-word inputs migrated to the real words (advanced); DSL grammar /
completion / phase-D / db tests parse in Simple mode (the DSL surface); replay
keeps its advanced-mode model (one stale assertion fixed); dispatcher routing,
combined-pointer, and internal-table tests added. Suite 1626 pass / 0 fail /
1 ignored; clippy --all-targets -D warnings clean.
Defer M4 (execution-time mode side-channel; tracked in requirements.md) to its
own ADR.
Extend SchemaCache TableColumn with not_null + has_default (with a
TableColumn::new constructor for the common no-constraint case),
populated in build_schema_cache from ColumnDescription (a PK column
counts as not-null). New dml_not_null_missing_diagnostics pass: a
WARNING when a SQL INSERT's explicit column list omits a column that
is NOT NULL with no DEFAULT — advisory (the engine enforces it).
serial/shortid (auto-filled) and defaulted columns are excluded.
Anchored on the target-table ident (no token for the omitted column).
Catalog key diagnostic.not_null_missing (engine-neutral). Tests (+4):
fires on omitted required column; silent when included, when
defaulted, and for auto-gen serial/shortid. ~24 TableColumn literal
sites updated for the two new fields (build clean). 1591 pass / 0
fail / 1 ignored. Clippy clean.
All three ADR-0033 §8 DML diagnostics now implemented. Remaining 3i:
cross-cut verification + #12 UPSERT DO UPDATE validation.
on_conflict_clause on SQL_INSERT_SHAPE: optional (col,…) conflict
target (distinct conflict_target_column role so it never enters
listed_columns), DO NOTHING / DO UPDATE SET … [WHERE …]. `do` is
factored out of the action Choice so nothing/update disambiguate
without tripping the walk_seq/walk_choice shared-prefix trap
(ADR-0033 Amendment 1). Worker runs the UPSERT verbatim (SQLite
native); no new execution path.
build_sql_insert: row_source now stops before the FIRST trailing
clause — ON CONFLICT (3h) or RETURNING (3g) — and do_sql_insert's
shortid auto-fill rewrite re-appends the whole trailing tail, so an
auto-filled INSERT keeps its ON CONFLICT / RETURNING.
excluded pseudo-table (§9): resolves to the target's columns inside
the DO UPDATE action and completes at `excluded.|`, but stays flagged
as unknown_qualifier in VALUES / RETURNING / non-upsert statements.
Diagnostic pass scopes it by the DO UPDATE byte-range (update token →
RETURNING/end); completion resolves it against the INSERT target's
current_table_columns. NOTE: scoping uses byte-range rather than the
plan's prescribed from_scope TableBinding push — same behaviour, no
walker scope-frame change.
Tests (+13): grammar accept/reject; DO NOTHING / DO UPDATE-excluded /
no-target execution + persistence; auto-fill × ON CONFLICT with a
REAL unique conflict (proves the clause survives the rewrite, not a
no-op); excluded resolves in DO UPDATE SET + WHERE, flagged in VALUES
(incl. same statement), unknown column under excluded; excluded.|
completion; conflict-target not in listed_columns. 1576 pass / 0 fail
/ 1 ignored. Clippy clean. Dev sql_insert entry word still removed in
3j.
Known follow-up (tracked for 3i): UPSERT DO UPDATE bare column refs
(SET LHS / WHERE) are not schema-validated, unlike regular UPDATE —
the INSERT target isn't a diagnostic binding. Fits 3i's cross-cut
SET/WHERE validation scope.
Shared RETURNING_CLAUSE (reuses Phase-2 PROJECTION_LIST, now
pub(crate)) as an optional tail on all three SQL DML shapes.
`returning: bool` on the Command variants, set by the ast-builders
and threaded to the worker. run_returning collects the returned rows
as a DataResult (RETURNING mutates + yields in one pass), reusing
resolve_select_column_types for bare-column type recovery; computed
projections stay typeless. DeleteResult gains a `data` field rendered
alongside the cascade summary.
Follow-set fix: `returning` is added to the table-source and
projection bare-alias follow-sets so an INSERT … SELECT row source
stops before RETURNING instead of reading it as a table alias.
Auto-fill × RETURNING: build_sql_insert stops row_source before the
RETURNING token (keeping it preparable for shortid materialisation),
and plan_shortid_autofill re-appends the RETURNING tail so generated
shortids surface in RETURNING *.
Tests (+17): grammar accept on all three; INSERT/UPDATE/DELETE
RETURNING incl. *, aliases, multi-row, type recovery + computed-
typeless; auto-fill × RETURNING (single + multi-row distinct ids);
INSERT…SELECT…RETURNING execution; UPDATE…RETURNING zero-match;
DELETE…RETURNING cascade+rows; app-level render of both. Dev
sql_insert/sql_update/sql_delete entry words still removed in 3j.
1562 pass / 0 fail / 1 ignored. Clippy clean.
A self-referential ON DELETE CASCADE FK (e.g. T.ParentId -> T.id) is
returned by read_relationships_inbound as a child whose table IS the
delete target. The before/after row-count diff then includes the
directly-deleted rows (already in rows_affected), so deleting a chain
root reported 3 cascaded rows when only 2 were removed via the
self-reference.
Fix in both do_delete (DSL) and do_sql_delete (SQL): when the child
table equals the target, subtract rows_affected from the diff and
guard on the corrected count (a leaf delete no longer reports a
phantom 0-row self-cascade); the target's CSV is already queued, so a
self-ref child is not re-added to rewritten_tables. Pre-existing in
do_delete; surfaced by the 3f DA pass, fixed in both paths to keep
DSL/SQL parity. Behaviour: report only the rows removed via the
self-reference (user-confirmed).
Also adds an app-level render test for the SQL DELETE path
(handle_dsl_delete_success via CommandOutcome::Delete) — the shared
renderer's ok-summary + per-relationship cascade line were exercised
only through the DSL path before.
Test-first: self_referential_cascade_counts_only_cascaded_rows added
for both paths (asserted 2, failed at 3 before the fix). 1545 pass /
0 fail / 1 ignored. Clippy clean.
New src/dsl/grammar/sql_delete.rs (FROM <table> [WHERE] [;]),
Command::SqlDelete, Request::RunSqlDelete, do_sql_delete worker.
do_sql_delete mirrors the DSL do_delete: detect FK cascade by
before/after child row-count diffing, re-persist target + every
cascade-affected child, history-on-success inside the tx. Reuses
CommandOutcome::Delete -> handle_dsl_delete_success, so the
per-relationship cascade summary formatter is shared, not duplicated.
ADR-0033 Amendment 2: supersedes §7's WHERE-injected pre-count. Its
premise (DSL handler builds pre-counts from the typed Expr) was wrong
— do_delete uses count-diff. The pre-count would also have broken the
§2 parity promise by reporting SET NULL the DSL path doesn't. Count-
diff gives exact parity, no WHERE-byte extraction, and withdraws R2.
SET NULL reporting deferred for both paths (user-confirmed).
Tests: +6 grammar unit, +12 integration (cascade parity with DSL,
both R2 subquery cases, before-execute order, no-WHERE, FK-rejection
rollback, childless-parent, two-child cascade). 1542 pass / 0 fail /
1 ignored. Clippy clean. Dev sql_delete entry word removed in 3j.
New src/dsl/grammar/sql_update.rs: SQL_UPDATE_SHAPE =
<table> SET col = sql_expr (',' …)* [WHERE sql_expr] [';'], the
__rdbms_* target rejection, and the shared sql_expr on both the
assignment RHS and the predicate. No --all-rows rail — a SQL
UPDATE without WHERE runs as written (ADR-0030 §12). Reuses
sql_select::WHERE_CLAUSE (now pub(crate)) so the predicate
diagnostics are identical. The target uses the shared `table_name`
ident role (not a bespoke one) so the Phase-2 schema-existence and
predicate-warning passes collect it as a scope binding and check
the SET / WHERE columns for free — a bespoke role left them
unchecked (the cross-cut tests caught this).
Command::SqlUpdate { sql, target_table }; Request::RunSqlUpdate +
do_sql_update (execute validated SQL via execute_with_fk_enrichment,
re-persist the target CSV, append history.log). 3e surfaces the
affected-row count only; precise row output is RETURNING (3g), so
the update-success render skips a column-less data set rather than
showing a misleading "(no rows)" band. Behind the dev `sql_update`
entry word until 3j.
Tests: grammar accept/reject; integration (single/multi-col,
no-WHERE all-rows, sql_expr in SET, scalar subquery in SET,
zero-match success, history); walker cross-cut (unknown SET column
→ unknown_column, `= NULL` in WHERE → eq_null warning); app-level
render-guard both ways (column-less → count only; with columns →
table renders). 1524 green, clippy clean.
plan_shortid_autofill read exactly listed_columns.len() cells from
the materialised row source. When the row source produced a
different column count than the user's list, the extra columns were
silently dropped (wider → wrong data, insert succeeded) or read
out of range (narrower). Guard: if the materialised statement's
column_count differs from the listed-column count, skip auto-fill
and execute the verbatim statement so the engine reports the
mismatch — matching the non-auto-fill path. A friendly pre-flight
diagnostic remains sub-phase 3i.
Tests: VALUES with too many values; INSERT…SELECT with a wider and
a narrower projection — each rejected with nothing persisted.
When an INSERT's column list omits one or more shortid columns,
the worker now fills them. Command::SqlInsert gains listed_columns
and row_source, captured in build_sql_insert from the matched path
(the row source is located by the first values/select/with Word
token, so a string literal like 'select' can't be mistaken for the
keyword). do_sql_insert calls plan_shortid_autofill, which — per
the user-confirmed Option B — materialises the row source by
running it as a query, generates a distinct shortid per row via the
existing generate_shortid_batch (deduped against stored values),
and reconstructs a parameterised multi-row INSERT over the listed
columns plus the omitted shortid columns. Uniform for VALUES and
INSERT…SELECT, and handles multiple omitted shortids in one row
(each gets its own batch). No explicit list, no omitted shortid, or
a zero-row source → execute verbatim (the 3b path). serial stays
engine-filled via rowid. history.log keeps the original line, never
the rewrite (§11).
Tests: VALUES single/multi-row distinct; explicit override
honoured; INSERT…SELECT distinct fills; combined serial(engine) +
shortid(worker); two shortids (PK + non-PK) both fill; one provided
+ one omitted; compound-PK shortid member; mixed-case column name
(ADR-0009 DA gate); original-source-in-history on the rewrite path.
Still behind the dev `sqlinsert` entry word (3j). 1503 green,
clippy clean.
Make the INSERT row source a Choice between the VALUES clause and
Subgrammar(&sql_select::SQL_SELECT_COMPOUND). SQL_SELECT_COMPOUND
is itself a Choice that admits a leading WITH, so a WITH-prefixed
SELECT row source (R4) parses through it for free; the two
branches start on disjoint keywords (values vs select/with) so the
Choice never ambiguously commits. No worker change — do_sql_insert
already executes the validated SQL and re-persists, and the engine
handles insert-from-query.
Tests: grammar accept (plain / column-list+projection / WITH-
prefixed / trailing-semi) and reject (__rdbms_* on the SELECT's
FROM slot, incomplete select); integration parse-path lowering +
worker round-trip (rows land, CSV re-persisted) incl. R4 WITH end-
to-end; walker cross-cut that the Phase-2 unknown_column diagnostic
fires on the INSERT…SELECT projection; DA-gate test that a self-
sourced INSERT…SELECT runs as a plain insert (no cascade summary —
that is DELETE-only). Still behind the dev `sqlinsert` entry word
(shared `insert` is 3j). 1493 tests green, clippy clean.
walk_repeated discarded the last matched item's trailing-optional
expectations at a clean item boundary, so a comma-separated list
offered no continuation after a complete item: `order by Name `
gave no asc/desc, `select Name ` no `as`, `create table …
Code(text) ` no not/unique/default/check. Capture the last item's
skipped set and surface it when the list ends at an item boundary
(the separator `,` itself is deliberately not surfaced).
That fix made expression-position candidate lists long, which
exposed a visibility problem: the hint panel's candidate line is
single-row and window-scrolls on overflow, centring on item 0 when
nothing is selected — so with keywords-first, schema identifiers
scrolled off behind the `>` marker. Reverse the ordering: schema
identifiers (table/column/relationship names) now sort before
keywords, since a name the user would have to look up is the
highest-value completion and must stay visible (keywords are
learned over time; the tok_identifier/tok_keyword colour split
marks the boundary). This reverses the handoff-14 keywords-first
call, now recorded in ADR-0022 Amendment 2.
Tests: walker expected-set + completion-layer regressions for the
trailing-optionals and the ordering; candidate_ordering.rs header
invariant inverted; ~20 typing-surface snapshots re-baselined; a
two-line hint box recorded as a deferred follow-up.
SQL_INSERT_SHAPE (INTO <table> [(cols)] VALUES tuple(s)) with __rdbms_*
target rejection; Command::SqlInsert{sql,target_table}; Request::RunSqlInsert
+ do_sql_insert worker (tx-guarded: execute, then finalize_persistence for
CSV + history before commit, so failures roll back and don't re-persist).
Auto-show is best-effort via last_insert_rowid range.
Isolated behind a dev `sqlinsert` entry word (Advanced) so the SQL path is
testable without making `insert` a shared word yet (that's 3j, after 3d
auto-fill parity). Command::SqlInsert carries only sql+target_table; the
plan's listed_columns/returning land in 3d/3g where they're read.
6 grammar accept/reject tests + 8 integration tests (single/multi-row,
column-list, full-arity, history, rollback-on-failure, multi-row atomicity,
parse-path reconstruction, internal-table rejection). 1452 baseline green.
Three DA critiques from the Phase-2 verification flagged real gaps;
this commit closes them.
1. Type recovery row-independence (critique #1). The all-10-types
test left col_blob NULL because the DSL Value enum has no Blob
variant. The DA flagged this as a potential row-dependence gap.
Added `database_run_select_type_recovery_works_on_empty_table`
that proves column-origin metadata works on Text AND Blob
columns with zero rows, pinning the invariant. The all-types
test now carries an explicit comment referencing it.
2. Engine.* pattern matching against real SQLite output (critique
#2). The pre-rework tests fed `translate_generic` hand-coded
strings; never verified that the pinned SQLite version actually
produces those wordings. Added three engine-routing tests in
`tests/sql_select.rs` that produce real engine errors via
`run_select` and assert catalog routing. Aggregate-in-WHERE
confirms end-to-end. GROUP-BY-required and scalar-subquery
are SQLite-permissive (no real error on the natural triggers),
so those tests verify the matcher doesn't false-positive on
benign queries + that synthetic messages route correctly.
3. Manual TUI verification (critique #3) surfaced an additional
gap: `App::input_validity_verdict()` was hard-coded silent in
Advanced mode, so SQL predicate warnings emitted but never
reached the [WRN] indicator. Wired the verdict through to the
active effective mode; updated two pre-existing tests that
pinned the now-superseded "silent in Advanced" behavior; added
one new test confirming a SQL `LIKE`-on-numeric warning fires
the indicator. Launched the TUI, typed a representative
warning-triggering SELECT, confirmed SELECT/FROM/WHERE/LIKE
highlight as keyword colour AND the [WRN] indicator appears.
Test totals: 1441 → 1446 passing (+5). Clippy clean.
Cross-cut verification matrix for ADR-0032 Phase 2 is now fully
populated with concrete test references — every row green. Filling
the matrix surfaced three real gaps that this commit closes.
1. Advanced-mode syntax highlighting (ADR-0030 §8 matrix row).
The `ui.rs` Advanced branch routed through `plain_input_spans`,
bypassing the highlight walker entirely. In production SQL
keywords past the entry word rendered as plain identifiers.
Fix: mode-aware variants of `highlight_runs`,
`render_input_runs`, `lex_to_runs`, and `input_diagnostics`;
the Advanced render path now uses the highlighted form with
`Mode::Advanced`. `plain_input_spans` removed (unused).
2. Engine.* key wiring (ADR-0032 §11.4 / §13 matrix rows + handoff
§3.3 follow-up). The four Phase-2 engine.* catalog entries
were authored in 2d but never reached: `translate_generic`
discarded the engine message and returned a vague catalog
entry. Fix: pattern-match the engine message text for the four
Phase-2 categories (aggregate misuse, group-by required,
compound arity mismatch fallback, scalar-subquery cardinality)
inside `translate_generic`, routing each to its engine-neutral
catalog entry.
3. Matrix-coverage tests. Thirteen new tests covering the rows
that had no explicit coverage:
- 3 SQL keyword/operator/CASE highlight tests
- 4 engine.* engine-message tests
- 3 sql_expr column-completion tests (WHERE, HAVING)
- 3 predicate-warning slot tests (CASE, ORDER BY, projection)
- 1 all-10-playground-types recovery test (tests/sql_select.rs)
Plan document (docs/plans/20260520-adr-0032-phase-2.md) updated:
every (TBD) row in the cross-cut matrix replaced with a concrete
test file::function reference and a green status marker.
Test totals: 1428 → 1441 passing (+13 new). Clippy clean.
`Cargo.toml`: add `column_metadata` to rusqlite's feature list.
This pulls in the SQLite `SQLITE_ENABLE_COLUMN_METADATA`
compile flag and surfaces `sqlite3_column_table_name` /
`sqlite3_column_origin_name` on prepared statements via
rusqlite's `Statement::columns_with_metadata()`.
`do_run_select` in db.rs now calls a new
`resolve_select_column_types(conn, stmt)` helper after
`prepare`. The helper walks each result-column's origin
metadata; when both `table_name` and `origin_name` come back
populated (the result column traces back to a base-table
column), it looks up the playground type in
`__rdbms_playground_columns`. The per-column types thread
through to `format_cell(value, ty)` so the data-table
renderer (ADR-0016) gets the same per-type rendering it
applies to `show data` results.
Effect: ADR-0030 Phase-1 §4.5 (bool SELECT results render as
`0` / `1`) is lifted for any bare-column reference whose
origin the engine carries through — per ADR-0032 Amendment 1
(2026-05-20 empirical probe), that means all non-recursive
CTE bodies, scalar subqueries (aliased or not), derived
tables, set ops, and JOINs. Computed projections and
recursive-CTE result columns remain typeless (the engine
populates no origin), which the renderer handles via neutral
alignment.
The lookup is engine-driven verbatim — no grammar-side
structural classification (ADR-0032 Amendment 1 replaces
§12's original "structurally a single column reference" rule
with "trust column_table_name / column_origin_name").
Tests (3 new in `tests/sql_select.rs`, all green):
- `database_run_select_recovers_bool_column_type` — the
Phase-1 §4.5 case: `SELECT Active FROM Products` returns
`column_types = [Some(Bool)]` and rows render as `true` /
`false`.
- `database_run_select_recovers_text_type_through_alias` —
`SELECT Name AS n FROM Users` remaps the result column
name to `n` but the origin metadata still resolves the
playground type to `Some(Text)`.
- `database_run_select_computed_expression_stays_typeless`
— `SELECT Score + 1 FROM T` keeps `column_types[0] =
None`, the documented Amendment-1 exception.
The CTE pass-through, scalar subquery, set-op, and JOIN
cases all work for free given the empirical findings;
their behaviour is asserted by the Amendment-1 probe
results recorded in the ADR, so no per-case integration
tests are duplicated here.
Test totals: 1382 → 1385 passing (+3), 0 failed, 1 ignored.
Clippy clean.
`tests/sql_select.rs` covers the full advanced-mode SELECT path
end to end (ADR-0030 Phase 1, ADR-0031):
App-level dispatch
- `advanced_mode_select_dispatches_as_command_select`: an
advanced-mode `select 1` produces exactly one
`Action::ExecuteDsl { command: Command::Select { sql }, .. }`
carrying the validated SQL text.
- `simple_mode_select_yields_sql_hint_and_does_not_dispatch`:
a simple-mode `select` produces no dispatch action and the
error output contains the SQL hint naming both recovery
paths (`mode advanced` / the `:` one-shot).
- `colon_one_shot_from_simple_mode_dispatches_select`:
`:select 1` keeps the persistent mode as `Simple` while
dispatching `Command::Select` with the `:` stripped.
- `advanced_mode_select_from_internal_table_is_rejected`:
a SELECT against `__rdbms_playground_columns` is refused by
the grammar's `reject_internal_table` validator.
Worker round-trip
- `database_run_select_constant_returns_a_single_row`:
`select 1` runs through `Database::run_select` and returns
a `DataResult` with one row whose only cell is `1`; all
`column_types` are `None` (ADR-0030 §6).
- `database_run_select_from_user_table_returns_inserted_rows`:
create-table → insert → `select Name from T` round-trips
the inserted row through the worker.
- `database_run_select_appends_to_history_when_source_present`:
the literal source line lands in `history.log` so replay
re-runs it (ADR-0030 §11).
The first cut of advanced-mode SQL: a `select` line in advanced
mode parses, runs against the database, and renders its rows
through the existing data-table renderer; the same line in
simple mode lights up the precise "this is SQL" hint instead of
running.
Walker mode gate (ADR-0030 §2)
------------------------------
- `WalkContext` gains a `mode: Mode` field; `Mode` derives
`Default` (= `Simple`, matching the app's startup mode).
- `grammar::is_advanced_only` keys an advanced-only entry-word
set (Phase 1: just `select`). When the walker matches an
advanced-only entry word with `ctx.mode == Simple`, it
short-circuits to a `WalkOutcome::ValidationFailed` carrying
the `advanced_mode.sql_in_simple` catalog key — the input
highlights as a keyword, the validity indicator goes ERROR,
and the parse-error layer renders the "switch with `mode
advanced`, or prefix the line with `:`" hint.
- `parser::parse_command_with_schema_in_mode` (and the
schemaless `parse_command_in_mode`) threads the mode into
`WalkContext`; existing `parse_command*` entry points default
to `Mode::Advanced` (most permissive) so back-compat callers
see the full grammar.
- `App::submit` is unified: both modes route through
`dispatch_dsl(&effective_input, effective_mode)`, which now
parses with the line's effective mode. The placeholder
advanced-mode echo branch is gone.
Builder signature sweep (ADR-0031 §2)
-------------------------------------
- `CommandNode.ast_builder` gains a `source: &str` parameter,
forwarded by the walker. `build_select` reads it to put the
validated SQL text into `Command::Select`; the 21 existing
builders accept it as `_source`.
SQL `SELECT` (ADR-0030 §6, ADR-0031)
-------------------------------------
- New `Command::Select { sql: String }` variant. Every
exhaustive `match Command` updated (`verb`, `target_table`,
`build_translate_context`, `execute_command_typed`,
`typing_surface`'s label).
- `grammar::data::SELECT` `CommandNode`: projection (`*` or
`expr [as alias]` list), optional `FROM <table>`, optional
`WHERE`/`ORDER BY`/`LIMIT`, optional trailing `;`. The
expression slots reference the ADR-0031 fragment through
`Subgrammar(&sql_expr::SQL_OR_EXPR)`. The `FROM` table-name
slot carries a `reject_internal_table` validator that
refuses `__rdbms_*` references at parse time.
- The `FROM` clause is optional — `select 1`, `select upper('x')`
(zero-table constant/function-call SELECTs) work alongside
the single-table form. Standard SQL admits them and they are
the canonical learner probe.
- Implicit projection aliasing (`select a x`) is deliberately
unsupported — `from` is a keyword, the bare alias would be
ambiguous; only `select a as x` is admitted.
Worker / runtime
----------------
- `Request::RunSelect { sql, source, reply }` + a new
`Database::run_select` method. `do_run_select_request` runs
the prepared statement, collects rows into a `DataResult`
with `column_types: Vec<None>` (Phase-1 SELECT result columns
carry no playground type per ADR-0030 §6), and appends the
literal source line to `history.log` so replay re-runs it
(ADR-0030 §11).
- `runtime::execute_command_typed` gains a `Command::Select`
arm that calls `database.run_select(sql, src)` and maps to
`CommandOutcome::Query`, which flows into the existing
`AppEvent::DslDataSucceeded` → `render_data_table` path.
Catalog (ADR-0019)
------------------
- `advanced_mode.sql_in_simple` — the walker's gate message.
- `select.internal_table` — the `__rdbms_*` rejection.
- `parse.usage.select` — the parse-error usage template.
Tests
-----
Two `app::tests` cases that pinned the pre-ADR-0030 placeholder
echo are updated to pin the new dispatch contract — both verify
that the advanced-mode `select` (one persistent, one via the
`:` one-shot) produces `ExecuteDsl(Command::Select)` with the
submission's effective mode tagged on the echo. The matching
walking-skeleton test is updated likewise.
A separate follow-up commit lands the ambient mode-threading
(completion / live overlay / validity indicator) so simple-mode
users do not see SQL surfaced through Tab or the live error
overlay either — the dispatch-layer gate landed here is the
behavioural foundation that follow-up builds on. Integration
tests for the full end-to-end land in a third commit.
Completes ADR-0029's implementation: the friendly-error layer
now names the rule a CHECK violation broke, and the
typing-surface matrix covers the whole constraint grammar.
CHECK-violation friendly error (ADR-0029 §10):
- enrich_dsl_failure gains a CHECK branch — it reads the column
from the engine's `CHECK constraint failed: <column>`
message, then resolves the table, the offending value, and
the column's compiled CHECK expression.
- FailureContext / TranslateContext carry the resolved
check_rule; translate_check renders "the value <v> breaks the
rule `<rule>`" when it is known, falling back to the plain
hint otherwise.
Typing-surface matrix: a new `constraints` submodule, 14 cells
covering the create-table / add-column constraint suffix and
the add-constraint / drop-constraint commands (174 → 188).
16 tests added (1 translate unit, 1 enrichment integration, 14
matrix cells).
Adds the two commands for modifying a column's constraints after
creation, completing ADR-0029's §2.2 surface.
Grammar (dsl/grammar/ddl.rs): `add constraint <constraint> to
<T>.<col>` reuses the §2.1 COLUMN_CONSTRAINT choice; `drop
constraint <kind> from <T>.<col>` names only the kind. Both join
the `add` / `drop` choices, discriminated by the `constraint`
form word.
AST (dsl/command.rs): `Command::AddConstraint` / `DropConstraint`
plus the `Constraint` / `ConstraintKind` enums.
Worker (db.rs): `do_add_constraint` / `do_drop_constraint` apply
the change through the rebuild-table primitive. `add` runs the §5
dry-run first — `not null` / `unique` / `check` against a
populated column are refused, before any write, with a
pretty-printed table of offending rows. §9 redundant-on-PK
declarations and §6 `default` on an auto-generated column are
friendly refusals; dropping a constraint the column does not
carry is likewise refused.
Also fixes schema_to_ddl, which suppressed UNIQUE for every PK
column — a compound-PK member is not individually unique, so an
explicit UNIQUE on it must survive the rebuild.
23 tests added (6 grammar, 17 worker); 3 completion-test and 3
matrix snapshots updated for the new `constraint` subcommand.
The fourth constraint. `check ( <expr> )` reuses the ADR-0026
WHERE-expression grammar via `Subgrammar`, so a check is
written in the same language as a `where` filter.
- Grammar: a `CHECK_CONSTRAINT` arm joins the shared
constraint-suffix Choice; `consume_check_expr` extracts the
parenthesised expression (paren-depth aware) into
`ColumnSpec.check` / `Command::AddColumn.check`.
- Storage: the parsed `Expr` is compiled once to inline SQL
(`compile_check_sql` — `compile_expr` + ADR-0028's
param-inliner) and stored in that form everywhere — a new
`check_expr` column in `__rdbms_playground_columns`,
`project.yaml`'s `ColumnSchema.check`, and the column DDL
emitted by `do_create_table` / `schema_to_ddl`.
- `add column … check` routes through the rebuild primitive
(SQLite's `ALTER … ADD COLUMN` cannot carry it); a CHECK on
a serial/shortid column is create-table-only and refused at
add-column with a friendly message.
- `describe` surfaces the CHECK. ADR-0029 §7/§8 updated to the
SQL-form decision — double-quoted identifiers, consistent
with ADR-0028's `explain` display SQL.
1201 tests pass (+8); clippy clean.
The database layer now honours the ColumnSpec constraint
fields end to end, ahead of the grammar that lets users type
them.
- `do_create_table` emits ` NOT NULL` / ` UNIQUE` / ` DEFAULT
<literal>` per column via the new `column_constraints_sql`
helper (the default literal bound against the column's type).
- `ReadColumn` gains `default_sql`, read from
`pragma_table_info.dflt_value`; `schema_to_ddl` emits it, so
the rebuild-table primitive preserves DEFAULT — it already
preserved NOT NULL / UNIQUE.
- `ColumnDescription` gains `unique` / `default`;
`do_describe_table` now sources columns from `read_schema`
(one source of per-column truth) and `constraints_display`
lists PK / NOT NULL / UNIQUE / DEFAULT.
No user-facing change yet — no grammar produces constrained
columns. Tests exercise creation, enforcement, describe, and
rebuild-preservation programmatically.
1177 tests pass (+5); clippy clean.
Expand ColumnSpec and Command::AddColumn with the four
ADR-0029 constraint slots (not_null, unique, default, check),
all defaulting off; `Database::add_column` now takes a
ColumnSpec. No behaviour change — the grammar to set the
fields and the DDL to enforce them land in the following
commits. Isolated here so those commits stay readable.
Adds ColumnSpec::new for the unconstrained case; 110 call
sites updated. 1172 tests pass; clippy clean.
13 matrix cells for the `explain` prefix across all three
wrapped commands — `explain show data` / `explain update` /
`explain delete` — covering each typing position (after the
prefix, the inner entry word, the table, the filter clause)
plus the three complete forms. The cells confirm `explain`
plugs into the inner query grammars cleanly: candidates, hints
and column scoping match the standalone commands, and the
complete forms parse as `Command::Explain`.
Also adds a worker test pinning the display SQL's `<>`
rendering of inequality (ADR-0028 §3).
Matrix: 161 -> 174 cells. 1172 tests pass; clippy clean.
Add the `explain` prefix command — `explain show data`,
`explain update`, `explain delete` — from grammar through to a
rendered plan tree.
- Grammar: an `EXPLAIN` CommandNode whose shape is a Choice over
the three explainable query shapes, referenced (not
duplicated) through `Subgrammar`. `Command::Explain { query:
Box<Self> }`; `build_show_data` is extracted so the role-based
builders serve both standalone and explain-wrapped commands.
- Worker: SQL construction is split out of do_query_data /
do_update / do_delete into `build_*_sql`, so EXPLAIN QUERY
PLAN runs the exact same statement. `Request::ExplainPlan` /
`do_explain_plan` capture the plan; `QueryPlan` / `ExplainRow`
carry it back. EXPLAIN QUERY PLAN never executes, so
explaining update/delete changes nothing.
- Display SQL: the executed statement with `?N` parameters
inlined as standard-SQL literals via a quote-aware scan.
- Render: `render_explain_plan` draws the box-drawing plan tree
(plain output; ADR-0028 step 4 adds the styled tree).
- Catalog: `parse.usage.explain` and the `help.data.explain`
entry, so `explain` shows up in the in-app `help` listing.
1151 tests pass (+18); clippy clean.
ambient_hint now reads the walker's schema-aware diagnostics.
input_diagnostics is non-empty only for a command that
structurally parses — so a non-empty result means "complete
and submittable, but wrong or dubious". That is checked early
(right after the Tab-cycle memo), ahead of slot hints and
completions: a command that parses but is flawed no longer
gets the misleading "Submit with Enter" prose, it gets the
diagnostic's why. pick_hint_diagnostic prefers the diagnostic
under the cursor, else the most severe.
The cursor-local invalid-ident hint is kept for genuinely
incomplete commands (no Match → no diagnostics).
5 ambient_hint tests (unknown table, type-mismatch over
submit-prose, LIKE-numeric, clean command still submittable,
cursor-following). The complex_and_or matrix cell referenced a
non-existent column `t`; fixed to a real column so it tests a
valid expression as intended. 1118 passing, clippy clean.
Adds the `[ERR]` / `[WRN]` validity indicator to the input
row. `App` gains `input_indicator: Option<Severity>` (the
runtime owns its timing — step E) and a pure
`input_validity_verdict()` query that runs `input_verdict`
in simple mode only (advanced mode is raw SQL, ADR-0027 §7).
`render_input_panel` reserves the rightmost six columns of
the input row unconditionally (ADR-0027 §4) — a five-column
label plus a one-column gap — so the typed command never
shifts sideways when the indicator appears or hides. The
label renders only when `input_indicator` is set: `[ERR]` in
`theme.error`, `[WRN]` in the new amber `theme.warning`
(defined for both light and dark themes).
The indicator is not yet wired live — `input_indicator`
stays `None` until the debounce lands (step E). Covered by a
render test and the theme contrast test; the input-panel
snapshot is updated for the six-column reservation.
Adds tests/typing_surface/where_expression.rs — 9 matrix
cells for the complex WHERE / show-data limit typing surface:
operator candidates after an operand, AND / OR after a
predicate, NOT, BETWEEN / IN bounds, and `show data`
where / limit.
Writing the cells surfaced a grammar bug. `predicate_tail`'s
`[NOT] negatable` branch started with `Optional(not)`, and an
Optional-first `Seq` always "commits" — so on an incomplete
input the walker's `Choice` returned that branch's
`Incomplete` early and discarded every sibling branch's
expected set, dropping `is` and the comparison operators from
completion after a column. Fixed by splitting it into
explicit `NOT negatable` and bare `negatable` branches — no
`predicate_tail` branch starts with an `Optional` now. The
matched terminal sequence is unchanged, so `build_expr` is
untouched.
Docs: ADR-0026 gains an "As-built notes" section recording
the option-1 builder realization, its two deviations from the
§3 sketch, and the deferral of §7 diagnostic flagging to
ADR-0027. requirements.md C5a -> [x] (steps 1-4) with the
test baseline refreshed to 1079; CLAUDE.md's deferred list
reconciled (C5a implemented; the QA1/QA2 note now points at
ADR-0028).
Wires the stratified WHERE-expression fragment into the three
filter commands and compiles the resulting Expr to SQL.
Grammar (data.rs): the `update` / `delete` `where` clause is
now the expression fragment (`Subgrammar(&expr::OR_EXPR)`) in
place of the single `col = val` slot; `show data` gains an
optional `where <expr>` and an optional `limit <n>` (a
non-negative integer, validated at parse time). The
expression's right-hand operands are a schema-aware
`DynamicSubgrammar` so the hint panel still narrows to the
left column's type (ADR-0026 §8) — but the inner grammar is
permissive: a type-mismatched literal still parses (§7).
AST: `RowFilter::Where{column,value}` -> `RowFilter::Where(Expr)`;
`ShowData` gains `filter: Option<Expr>` and `limit: Option<u64>`.
A `RowFilter::eq` convenience constructor keeps simple-equality
call sites and tests readable.
SQL (db.rs): `compile_expr` lowers an `Expr` to a
parameterised WHERE — every literal a `?` placeholder,
identifiers `quote_ident`-quoted, `<>` for inequality. A
literal compared against a column binds through that column's
type where compatible and falls back to its syntactic shape on
a mismatch (§7 — permissive). `show data ... limit n` emits
`LIMIT ?` with an implicit primary-key `ORDER BY`, so it is a
stable "first n by primary key".
completion.rs: `invalid_ident_at_cursor` no longer mis-flags a
digit-led literal (`1`) as an unknown column now that the
WHERE operand slot also accepts a column reference; a
`ProseOnly` slot suppresses keyword candidates even when the
expected set also carries a column ident.
11 db integration tests cover AND / OR / NOT, BETWEEN, IN,
LIKE, filtered `show data`, and limit ordering; walker and
expr unit tests cover the parse surface. Type-mismatch /
`= NULL` diagnostic flagging (§7 highlight + hint) is the
remaining ADR-0026 piece.
`create table … with pk` parsed column types as `name:type`,
while `add column` uses `name(type)`. Unify on the parens
form so column-type syntax is consistent across the DSL:
create table T with pk id(serial), name(text)
Only `COL_SPEC` changes (`:` → `( … )`); `build_create_table`
reads columns by role, so it is unaffected. The `:` that
separates table from column in `add column` / `drop column`
is unchanged. Sweeps the test suite, the typing-surface
matrix (two `after_colon` cells renamed to `after_paren`,
4 snapshots regenerated), the friendly catalog's usage
templates, ADR-0009's example, and requirements.md.
1039 passing / 0 failing / 1 ignored; clippy clean.
Implement ADR-0025 — indexes as a DSL DDL feature.
- Grammar: `add index [as <name>] on <T> (<cols>)`, `drop index
<name>` / `drop index on <T> (<cols>)`, plus a `--cascade`
flag on `drop column`.
- db.rs: index operations over the engine's native index
catalog (no metadata table). The rebuild-table primitive now
captures and recreates indexes, so `change column` and the
relationship operations no longer silently drop them.
- `drop column` refuses an indexed column unless `--cascade`,
which drops the covering indexes and reports each.
- Persistence: additive `indexes:` list in `project.yaml`
(version unchanged); round-trips through rebuild/export/import.
- Display: an `Indexes:` section in the structure view and a
nested tables/indexes items panel (S2).
Reconciles requirements.md (C3 index portion, S2 satisfied)
and CLAUDE.md. 1038 tests passing (+31), clippy clean.
run_replay parsed each line with the schemaless parse_command, so
Phase D typed-slot rejections (wrong-count value lists, wrong-type
column values) fired only at bind time during replay — inconsistent
with the interactive path (handoff-12 §2.1).
run_replay now re-snapshots the schema per line (the schema mutates
as replayed create-table / add-column commands run) and parses with
parse_command_with_schema. Extracted build_schema_cache, shared with
the interactive refresh_schema_cache.
Added a replay integration test asserting a typed-slot violation is
caught at parse time (through the replay.error_parse wrapper).
Form C (`insert into T (vals)`) shared the `(` opener with Form A,
so its paren was an untyped Repeated(Choice(literal, ident)) — values
weren't type- or count-checked at parse time (handoff-12 §2.2).
New Node::Lookahead variant: a factory that peeks the source. The
insert first-paren factory inspects the first token — a value literal
routes the contents through the typed column_value_list (Form B
dispatch contract: per-non-auto-column typed slots); an identifier or
empty paren routes to a Form A column-name list. So Form C now gets
the same per-column typed slots, hints, and parse-time type/count
checking Form B has.
The explicit-Choice-branch split is impossible here (committed-choice
semantics commit after `(` matches); lookahead is the only route, and
DynamicSubgrammar factories couldn't see the source. Node::Lookahead
is not memoized — its output depends on source — but it returns only
a small node (a Repeated, or a thin DynamicSubgrammar wrapper that
delegates to the memoized column_value_list).
`insert into T (` now cleanly shows Form A column candidates instead
of mixed Form-A/C suggestions. Form C matrix tests updated for the
type-aware behaviour.
Handoff-12 §2.2: Form B `insert into T values (…)` silently skips
auto-generated columns from the value list, so a user who wants to
set a serial/shortid column explicitly could only discover Form A by
reading help. Now the hint at the first Form B value slot appends a
note naming the skipped column(s) and pointing at the explicit-column
form.
hint_resolution_at_input derives the skipped columns from the
post-walk WalkContext (Form B = no user_listed_columns + table has
serial/shortid columns) and reports them on HintResolution; the note
fires only at the first slot so it doesn't repeat at every comma.
ambient_hint composes it onto the per-column prose.
8 tests covering completion-candidate order: connective keywords in
reading order (`to`/`from`/`in` before `table`), and command-part
keywords before schema identifiers. The ordering already held via
declaration-order preservation + keywords-first sectioning in
candidates_at_cursor; nothing pinned it until now, so a future
grammar or sort change could silently break the hint panel's
left-to-right reading.
55 tests covering create table, drop column, drop relationship
(endpoints + by-name), add relationship, rename/change column, and
all app-lifecycle commands. The drop-column and relationship tests
drove the §2.2 writes_table fix in the previous commit.
Documents one UX wrinkle as a flagged finding: partial entry words
(`qu`) classify as DefiniteErrorAt — same as unknown commands —
because the walker only engages on a complete entry word.
859 baseline -> 989 passing; 1 ignored (pre-existing doc-test).
34 new tests covering:
- Form C bare-value-list (happy path + Form-A-recovery + type-unaware grammar limitation per handoff §2.2)
- update with WHERE (column-narrowing invariant per handoff §1 bug E1; typed-slot prose for assignments and where filters)
- update --all-rows (filter-clause requirement per ADR-0014)
- delete with WHERE (column-narrowing; typed-slot prose for where filters)
- delete --all-rows
859 baseline -> 931 passing. No bugs surfaced — the data-mutation
command family was already well-shaped post-Phase-D.
12 tests across schema_serial_pk / text_pk / multi_table / every_type.
Pins (a) Form B skips auto-gen columns from the slot list (regression
for handoff-12 §B fix); (b) wrong-count value lists are now flagged
at typing time, not only at submit (the previous commit's fix); and
(c) per-type slot prose advances correctly through every Type variant.
Per docs/handoff/20260515-handoff-12.md §1. Systematic per-position
coverage of (state, hint, completion, parse_result) across canonical
schema shapes; submodule per command family. Insert Form A covers 23
cursor positions across serial-PK, text-PK, multi-table, and
every-Type schemas. Both bugs fixed in the previous commit were
surfaced by these tests.
Shared helpers under tests/typing_surface/mod.rs: 5 canonical schema
shapes, assess() helper, property-assertion shortcuts, and a snap!
macro that wraps insta with a stable per-cell suffix.
859 -> 885 tests passing; 1 ignored (pre-existing doc-test).
New `dsl::usage` module: registry pairing each command's
entry-keyword with a `parse.usage.*` catalog key.
`matched_entry()` resolves the entry keyword from the
consumed token prefix; multi-entry families (add, drop,
show) return all matching keys.
Catalog: new `parse.usage.<command>` keys (one per command),
`parse.token.{keyword,punct,...}` vocabulary (one per
Keyword/Punct variant + token-class labels + LexError
kinds), and `parse.available_commands` for the no-prefix
fallback. Catalog grows ~60 entries.
Validator: extended KEYS_AND_PLACEHOLDERS; new completeness
test asserts every Keyword and Punct variant has its
`parse.token.*` entry.
`app::dispatch_dsl` rewritten to compose three blocks per
ADR-0021 §2: caret + structural/custom error + usage block
(or available-commands fallback per §5). Caret math fixed
to use original-input byte position rather than
trimmed-input position (the lexer no longer trims before
lexing). Three pre-existing app tests adjusted to look
across all error lines instead of `output.back()` (the
usage block is now the last line).
`dsl::usage::matched_entry` uses `<=` rather than `<` for
position comparison so custom errors raised by `try_map`
(whose span starts at the first consumed token) still
resolve to the entry keyword.
Tests: 668 passing, 0 failing, 1 ignored (650 baseline →
+18: 8 usage + 1 token-vocab completeness + 9 new
integration tests in tests/parse_error_pedagogy.rs
covering create/add/drop/show/frobulate/update/insert
cases). Clippy clean.
Final pass of the i18n migration sweep. Every user-visible
string in `src/` now flows through the catalog via `t!()`.
## Categories migrated in this commit
- **help.cli_banner** — the entire `cli::HELP_TEXT` const,
formerly a 40-line `&'static str`, is now a YAML block in
the catalog. The const is replaced by a thin
`cli::help_text() -> String` wrapper that performs the
catalog lookup. `main.rs` calls `help_text()` for both
`--help` output and the args-parse error path. The two
integration tests that referenced `HELP_TEXT` directly are
updated.
- **help.in_app_body** — the in-app `help` command's body is
one YAML block; `note_help` becomes 5 lines that iterate
the lines and emit each as its own output row (preserving
the renderer's "one logical line = one display row"
invariant for accurate scroll math).
- **modal.*** — load picker, rebuild confirm, and save-as
path-entry strings: rebuild_cancelled, load_cancelled,
generic_cancelled, load_picker_nothing,
path_entry_empty_name, path_entry_empty_path.
- **dsl.failed** — the `"<verb> <subject>" failed: <rendered>`
wrapper around the friendly-error layer's translated
message.
- **dsl.running** — the `running: <input>` echo line shown
above each command's response. (Note: the en-US prefix
"running: " is hardcoded in the parse-error caret-padding
calculation. Translators changing the prefix must keep the
width consistent — documented inline.)
- **advanced_mode.not_implemented** — the placeholder echo
shown when SQL hits the unimplemented advanced-mode path
(Q1 territory).
- **fatal.persistence** — the FATAL banner for
PersistenceFatal events (ADR-0015 §8).
- **project.{load_path_missing,saveas_target_exists,**
**import_zip_missing}** — runtime-side project-switch
validation errors that surface via ProjectSwitchFailed.
## Catalog start-up ordering
`main.rs` now calls `friendly::catalog()` at the very top
(before args parsing) so `help_text()` works in both the
success path and the args-error path. A corrupted build
artefact still fails loudly with a useful panic; the
practical risk is essentially zero since the catalog is
`include_str!`'d at compile time and validated by the unit
test before shipping.
## Remaining literals
The only `note_*` calls in `src/` that still pass plain
strings are inside `#[cfg(test)]` modules — synthetic test
fixtures, not user-visible. The codebase passes the "every
user-visible string flows through the catalog" bar.
## Tally
610 tests passing (no change in count — pure refactor).
Clippy clean with nursery lints.
## What this closes
ADR-0019 §9 (migration sweep) — done.
ADR-0019 itself is now fully implemented:
- §1-§5: catalog + translator + voice + verbosity ✓ (`eac7e5b`)
- §6: row pinpointing + schema enrichment ✓ (`431645a`)
- §9: migration sweep ✓ (this + `aff528a`)
- §10: anchor phrases preserved throughout ✓
- The five "Out of scope" items remain explicitly bounded
to future ADRs (advanced-mode SQL, settings persistence,
pluralisation, runtime locale, value formatting,
constraint management).
Closes the placeholder-substitution gap reported during manual
testing: FK violations were rendering `<value>` and `<column>`
literally because the App had no schema awareness. With this
change the runtime resolves the schema-dependent facts before
the App ever sees the failure.
## Architecture
- **Database** gains two public methods backed by new worker
Request variants:
- `read_relationships(table)` → (outbound, inbound) FK list
(lifts the previously-private `read_relationships_*` pair
into the public surface, behind a `RelationshipsReply`
type alias).
- `find_rows_matching(table, column, value, limit)` →
`DataResult` for row pinpoint queries.
- **friendly module** gets:
- New `FailureContext` struct: schema-resolved facts the
runtime builds (table, column, value, parent_table,
parent_column, child_table, optional diagnostic_table).
- `TranslateContext` loses its lifetime parameter and gains
`parent_table` / `parent_column` fields. All string fields
are now `Option<String>` for ownership simplicity.
- `TranslateContext::from_facts(operation, verbosity, facts)`
helper.
- Translator's FK paths now use `ctx.parent_table` /
`ctx.parent_column` for child-side wording; FK Update gets
a dedicated `fk_child_side_update` arm.
- FK dispatch is enrichment-driven first
(`parent_table` set → child-side; `child_table` set →
parent-side), with operation as the tiebreaker.
- The translator forwards `ctx.diagnostic_table` onto the
`FriendlyError` so pinpointed rows render through the
existing ADR-0017 §7 bordered renderer.
- **Event** `DslFailed` carries `(command, error, facts)`.
The runtime populates `facts` via `enrich_dsl_failure`
before posting the event.
- **Runtime** `enrich_dsl_failure(database, command, error)`
classifies and resolves:
- UNIQUE INSERT/UPDATE: parses `T.col` from engine message,
finds the user's attempted value (with schema fallback
for natural-order multi-value INSERT — including the
serial/shortid auto-skip rule from `do_insert`), pinpoints
the existing conflicting row(s) via `find_rows_matching`
and renders as a `DiagnosticTable`.
- NOT NULL INSERT/UPDATE: parses `T.col`; no value
(definitionally null) and no pinpoint (engine doesn't
identify the row).
- FK INSERT/UPDATE: outbound relationship lookup picks the
FK column the user is touching; resolves
`parent_table`/`parent_column`/`value`. UPDATE falls back
to inbound (parent-side) when no outbound match.
- FK DELETE: inbound relationship lookup picks a child_table
that references this row.
- **App** drops its old `attempted_value_for` /
`column_from_qualified_target` helpers (their work moved to
runtime where the Database is in scope).
`build_translate_context` combines the runtime-supplied
facts with the operation derived from the Command and the
App's verbosity.
## Manual-test fixes folded in
Two issues surfaced during manual testing of the initial
implementation, both fixed:
1. Natural-order multi-value INSERT
(`insert into Orders values (4, 11.99)`) skipped FK
enrichment because `user_value_for_column` only knew the
single-value short form. The schema-aware lookup
(`user_value_for_column_with_schema`) now mirrors
`do_insert`'s position-mapping rule (auto-generated
columns skipped), so positional INSERTs onto tables with
serial/shortid PKs resolve correctly. Regression test:
`enrich_fk_insert_natural_order_multi_value_resolves_via_schema`.
2. The arity error on INSERT now lists the columns it
expected — `expected 3 value(s) for (id, Name, Email), got 2`
instead of the bare count. Surfaces what the user needs
to fix without making them go check the schema.
## Tests
`tests/friendly_enrichment.rs` (+8 integration tests):
- UNIQUE INSERT with explicit columns: facts.{table, column,
value, diagnostic_table} all resolved; pinpoint shows
conflicting row.
- UNIQUE INSERT natural-order short form: schema fallback
resolves the value.
- UNIQUE UPDATE: value pulled from assignments.
- NOT NULL INSERT: table+column resolved, value None
(correct), no pinpoint.
- FK INSERT: parent_table, parent_column, value all resolved
via outbound relationship lookup.
- FK INSERT natural-order multi-value: schema-aware lookup
with auto-skip resolves correctly (regression for the
manual-test bug).
- FK DELETE: child_table resolved via inbound relationship
lookup.
- DbError::Unsupported: enrichment returns default
FailureContext (no false positives).
App-level tests updated to populate `FailureContext` directly
(simulating runtime enrichment) for the verbosity / threading
checks.
## Tally
610 tests passing (was 603: +8 enrichment integration tests
minus 1 obsolete App-side helper test that the runtime
absorbed). Clippy clean with nursery lints. Release builds.
