Went looking for a clippy ratchet and found that clippy had never run on
this crate at all: two dependencies fail deny-by-default lints, so
`cargo clippy -p nigig-build` aborted before linting nigig-build. Fixing
those two unblocked the crate and immediately exposed a real defect
class.
THE BUG. A bare identifier in a match pattern that is not a known variant
is parsed by Rust as a NEW BINDING that matches everything. Nine such
names were used as KeyCode patterns:
KeyEnter, KeyBackspace, BracketLeft, BracketRight (cad/viewport.rs)
Digit0..Digit9, Equal, LeftBracket, RightBracket,
Apostrophe (doc, invoice, pm)
Real names are ReturnKey, Backspace, LBracket, RBracket, Key0..Key9,
Equals, Quote.
Consequences, in severity order:
- cad/viewport.rs: `BracketLeft => { .. }` is UNGUARDED and sits above
the numeric arms, so it swallowed every remaining key. All
direct-distance-entry input -- digits, '.', '-', ',' -- was
unreachable. The entire DDE feature was dead.
- The guarded ones fired for any key satisfying the guard: pressing Q
while drawing with a non-empty buffer committed the coordinate.
- doc/invoice/project_management: `Digit0 => '0'` swallowed the rest of
the keymap, so every digit and symbol typed produced '0'.
This compiles cleanly and no test catches it. rustc's only signal is
`unreachable_pattern` plus `unused variable: \`Capitalised\`` -- both
buried in the 200+ warnings nobody could see, because clippy never ran.
85 unreachable-pattern warnings before, 1 after (a benign catch-all).
UNBLOCKING CLIPPY. Two deny-level errors in dependencies:
- nigig-uikit user_project_pill.rs: a `for` loop returning on its first
iteration (never_loop). Rewritten as `.next()`.
- spreadsheet-engine formula2.rs: CellRef had an inherent to_string
shadowing Display (inherent_to_string_shadow_display). The naive fix is
a trap: Display::fmt was `f.write_str(&self.to_string())`, which
resolved to the inherent method -- delete it and the same call resolves
to ToString::to_string, which calls Display::fmt, recursing until the
stack overflows. Verified with a standalone repro before fixing. The
body moved into Display; Range got the Display impl it never had.
Tests: keycode_variant_tests names the four correct variants, so it stops
compiling if any is renamed -- the point being that the old code compiled
precisely because the names were wrong. Two formula2 tests pin that
`x.to_string()` and `format!("{x}")` agree, which is what the shadowing
lint exists to protect.
CI gate added and negative-tested: greps for a capitalised
`unused variable`, which is the signature of this bug. Restoring
BracketLeft makes it fire.
625 lib + 154 integration + 225 spreadsheet-engine + 44 doc-engine, 0
failed.
origin/main did not compile: E0716 in exchange_grid_with_model.
let Some(mut grid) = self.view.widget(cx, ids!(grid))
.borrow_mut::<SpreadsheetGrid>() else { return false; };
`widget()` returns a temporary WidgetRef and `borrow_mut` borrows from
it. In a `let ... else`, temporaries in the scrutinee are dropped at the
end of the statement rather than living to the end of the enclosing
block as they do in `if let`. So `grid` outlives what it borrows from.
The three neighbouring call sites use `if let` and are unaffected, which
is why this reads as correct next to them.
Bound the WidgetRef to a local first, with a comment recording the
`if let` / `let else` difference so the next copy-paste from a
neighbouring line does not reintroduce it.
Phase 4 of CAD_ASSESSMENT_AND_PLAN.md: remove the second copy of things
the module carried alongside their replacements. No behaviour change.
Removed, after confirming each has no live caller:
- The entire LegacyCommand system: the trait, LegacyCommandCtx,
LegacyUndoRedoStack and the six LegacyMovePart/Resize/Rotate/Add/Delete/
ModifyPart structs, plus their tests. The editor has used the Command /
UndoRedoStack pair since v19; the legacy set was still exported and
still maintained, so grepping for a command type returned two answers.
- CadViewport::legacy_ctx(), which nothing called.
- CommandError::Legacy, which was never constructed.
- The duplicate DofConstraint in mod.rs and its two bridge From impls.
Production reads cad_scene::DofConstraint exclusively; the legacy struct
existed only so a conversion test could round-trip it.
- Three dead functions in exporters.rs. The dead write_3d_viewer also
carried a bug the live path does not: it wrote an absolute filesystem
path into the exported viewer's <model-viewer src>, which breaks the
moment the folder is copied anywhere.
Renamed LegacyCommandCtxHolder -> CommandBorrows. Despite the name it
holds the *new* UndoRedoStack and is the split-borrow helper for the live
command path.
Also refreshed the v10/v13/v18b archaeology comments that referenced the
deleted types, and ported bench_command_execute_overhead to the live
Command/CadCommandCtx path so the measurement survives.
1,588 lines removed: commands.rs 1863 -> 1318, tests.rs 3754 -> 2840,
exporters.rs 186 -> 93.
Tests: 728 -> 714 passing, 0 failing. The 29 removed all exercised the
deleted system; verified by diffing the full test-name list before and
after, which also caught 16 live-system tests that merely *mentioned* a
Legacy type in passing and had to be kept.
Rebasing onto origin/main also required repairing that branch, which did
not compile (4 errors) and so had never run its own tests:
- lookup.rs: an over-eager .clone() removal left *bt.category, deref'ing a
String field to an unsized str and breaking the key type.
- estimate_store.rs: two different tests shared one name; renamed both to
say what they assert.
- Once building, 3 tests failed. EstimateStore::dispatch took an undo
snapshot and emitted UndoRedoChanged even when the command was a no-op,
so a rejected out-of-range edit still consumed an undo slot and cleared
the redo stack. Command::Initialize also never cleared the room list, so
re-initialising kept the previous run's rooms.
- spreadsheet-ui/workspace.rs: missing `use crate::model::WorkspaceModel`.
Phases 0-2 of CAD_ASSESSMENT_AND_PLAN.md. The crate did not compile and no
test had ever run; it now builds clean with a green suite.
Build and CI (Phase 0)
- Pin all 33 git dependency manifests to an explicit rev. A branch
dependency re-resolves on every build and is a code-execution path into
CI if force-pushed.
- Commit Cargo.lock (540 packages). Producing it required fixing three
resolution failures the workspace had always had: a non-existent
makepad-widgets feature, two rusqlite versions both linking sqlite3, and
four missed CellId call sites in spreadsheet-ui.
- Add .forgejo/workflows/nigig-build.yml.
- Replace five stale CAD docs that contradicted the code with one
ARCHITECTURE.md; add PHASE0/1/2_STATUS.md and TEST_BASELINE.md.
Correctness (Phase 1)
- Rotation units: transform_point bound sin_cos() backwards, transposed X
and Z, and applied axes in reverse order, so every exported STL was wrong
even at zero rotation. It now shares the renderer's matrix helpers.
- GLB quaternions had norm 0.125 (half-angle applied to cos/sin, degrees
read as radians) - invalid per the glTF spec.
- PDF wall/door/window yaw fed degrees to cos/sin.
- Fix a TOCTOU unwrap in touch picking; viewport.rs now has no unwrap().
- CommandContext gains update_node/insert_node_at/node_index: resize and
modify were delete+create, silently moving nodes to the end of the scene.
- Wire MAX_UNDO_LEVELS (defined, exported, never read) and switch the undo
stack to VecDeque; this also made the existing drag-merge logic reachable.
- CadNode::size() returned a fake 1x1x1 for CSG and extruded solids, making
them unpickable outside a 1x1x1 box at their origin.
- Reject non-finite script input; makepad_csg clamps NaN rather than
propagating it, so bad input produced silently wrong geometry.
Test baseline: 0 -> 722 passing, 0 failing
- 17 pre-existing failures fixed: 10 real defects (dependency-cycle
detection, over-allocation of unassigned tasks, quote/backslash
corruption on save, default rooms lost for all but the first region,
RGA text ordering) and 7 tests that were themselves wrong, each checked
against its production caller first.
Security (Phase 2)
- env!("CARGO_MANIFEST_DIR") was used as a runtime path in three places,
including as the AI agent's working directory. All runtime data now goes
under app_data_dir().
- Remove the hardcoded LAN LLM endpoint. It is now opt-in via
NIGIG_CAD_LOCAL_OPENAI_URL/_MODEL and refuses plaintext HTTP to anything
but loopback.
- Bound and content-sniff AI image attachments (8 MB cap, magic bytes);
the MIME type came from the filename extension.
- Escape SVG/HTML output, and add SRI to the exported viewer's script tag.
The pinned model-viewer@3.5.1 does not exist, so every exported viewer
was silently broken; now 4.0.0 with a verified hash.
- Stop embedding $USER in exported PDFs and logging document content in
release builds.
- CI now rejects reintroducing the runtime-path and hardcoded-endpoint
classes; both gates were verified to fail on a reintroduced defect.
Add system_prompt.md and embed it with include_str!. The file was missing
from the repository, so the agent silently used a one-line fallback.
