Moves the bulk memory case types, strategies and their test after arb_paint, so they no longer share the lines after output where other fuzz generators are added.
plugin_fuzz now builds plug-ins whose run executes memory.fill,
memory.copy (overlapping ranges included), memory.init followed by
data.drop, and data.drop followed by memory.init. Lengths and offsets
are sampled at zero, small, page and mebibyte sizes, at an exact end,
one before and one past it, with copy sources and destinations and init
memory and segment offsets chosen separately. Fill and copy can repeat
up to about one fuel slice of copying.
Each case runs directly under the default budget, a small fixed budget
or one near its estimated cost. A run must trap exactly when a range
leaves memory or the data segment (empty once dropped), and must finish
when it is in bounds and has ample fuel; otherwise it may hit the
instruction budget. The same plug-in then runs through plugin.run: a
failed run leaves the document unchanged and the document still renders
and exports.
bulk_memory_cases_reach_their_instruction checks that each operation's
module contains its instruction and traps on a small out-of-bounds case.
A top object's corner test treats a straight segment as having its
handles a third of the way along it, so an anchor between two straight
segments is a corner only when it turns out of the outline. docs/mcp.md
and the doc comment now say so, and a new test covers an inward anchor
between straight segments. The bulging-curve corner test checks against
a fixed point instead of the same nearest-point routine the code uses.
Saved corners from an .ai file stay on the same anchors when the
envelope is reflected, as they already did when it was moved or
rotated. A reflected outline runs counter-clockwise; the corners were
then mapped as if the outline had been drawn the other way round, no
longer fit it, and were found again from the outline.
On a tie between two corner anchors, or two nearest outline points,
the one met first along the outline in the order it was drawn wins,
for outlines drawn counter-clockwise too.
The docs state the corner rule in full: a handle 0.01 pt long or
shorter makes an anchor a corner whichever way it turns; otherwise its
tangent unit vectors must differ by 0.01 or more in x or y and turn
out of the outline. Content spreads evenly along a segment without
handles.
An anchor with a handle shorter than 0.01 pt counts as a corner of a top
object whichever way it turns; only an anchor whose tangents differ must
turn out of the outline. docs/mcp.md and the progress line in
docs/target-app-parity.md now say so.
A top-object envelope splits its outline into four sides at four corners
and maps the content onto the Coons patch of those sides. The sides
shared out the content by length, and the corners were the anchors or
curve points nearest the bounding box corners.
Each piece of a side between anchors and corners now takes a share of the
content's width or height in proportion to the length of its control
polygon, spread along the piece by its curve parameter. A straight
segment spreads it evenly by length. A rounded rectangle stays close to
the identity, and the content follows the curves of a side whose segments
differ in size.
Each corner is now the nearest anchor to its bounding box corner among
the sharp anchors that point out of the outline and lie within 47.5% of
the box's width and height from that corner. A handle shorter than
0.01 pt, or tangent unit vectors that differ by 0.01 or more in x or y,
makes an anchor sharp, and the first one along the outline wins a tie.
Without such an anchor, the corner is the outline's nearest point to the
box corner, moved onto the end anchor of its segment within 0.5% of the
segment's parameter. Envelopes opened from .ai files keep the corners the
file saves.
These are VectorCraft's own rules. Existing top-object envelopes redraw by
them. Gradient meshes made from a path keep their sides measured by length.
- crates/doc/src/live/mesh.rs: Coons::from_top_object and the corner
search, used for top-object envelopes.
- EnvelopeKind::TopObject gains an optional `corners` field (anchor
indices); the .ai importer fills it from the mesh's corners.
- Params text of object.envelope.makeWithTopObject, docs/mcp.md
(Envelopes) and a progress line in docs/target-app-parity.md.
Closing a document told the worker to forget every row whose document was
not open at that moment. The worker keeps that test until it is idle, so
while a job still ran, a document opened afterward had its rows dropped
and they stayed without thumbnails. The worker now forgets only the
documents that closed.
