A fresh web-vs-desktop audit found the remaining gaps; this closes the
top ten.
Raster images: IMAGE attach read the picked file via image::open on a
name-only path (dead on wasm), and raster references inside opened
drawings decoded the same way. Picked bytes are now registered in a
name-keyed store (the PDF-underlay pattern), decoding runs from memory,
and dropped .png/.jpg/.bmp/.tif files register by name so unresolved
references in opened drawings re-resolve and render (and export to PDF).
Command gaps fixed with the bytes-at-pick / download_bytes pattern:
- WBLOCK now downloads the extracted block instead of failing on fs.
- SAVEALL saves every dirty tab instead of printing a no-op message.
- SCRIPT picks and reads the .scr file through the browser picker.
- CENTERLTYPEFILE picks the .lin/.dnl file and populates from text.
- Custom .ctb tables picked on web now parse, register for the
session, appear in the plot dialog list, and apply (load_named
previously returned builtin-only on wasm).
- LAYTRANS 'Load standards file' parses the picked drawing on the
existing web worker.
- INSERT 'from file' in the block palette parses picked bytes and
feeds the shared import path.
Text fidelity: TTF-named styles rendered as thin stroke glyphs on web
because the font database was empty. Fetched Noto faces are now
registered into it with a family alias table (Arial, Times New Roman,
Cambria, ... -> Noto Sans/Serif), so those styles render filled, shape,
export to PDF as vector fills, and appear in the style picker.
ViewCube labels request semibold again on web.
docs/native-vs-web.md: the hatch and font rows were stale (both work on
web now), the GPU row claimed WebGPU is used where available (the
backend is pinned to OpenGL), and the parallelism row missed the parse
worker — all corrected.
(cherry picked from commit c643a10e)
Ported onto main (#1717 review): conflicts resolved toward main — the
font-file lookup, PDF searchable text, purge service, block palette and
plot-style copy stay as they are on main; the web pieces (font registry
and aliases, session plot styles, SCRIPT/SAVEALL/CENTERLTYPEFILE picks,
block-from-file on the web) are layered on top.
Three attack agents (state-machine tracing, executable input fuzzing,
browser-API review) found two breaks and several degradations; all are
fixed here, with the fuzzer's 22 tests kept as regression suites.
Breaks:
- Untitled tabs (and dot-names like ".dxf") autosave as DXF, but the
restore name defaulted to .dwg — the worker dispatches its reader by
the name's extension, so the only copy of unsaved work could never
be restored and was re-offered forever. recovered_name now uses the
worker's rsplit('.') convention and defaults extensionless names to
dxf, matching new-document serialization.
- " (recovered)" stacked one suffix per crash-restore cycle; the
marker is now stripped idempotently before appending.
- Opening a file (Ctrl+O / OPEN / automation) while a web open was in
flight clobbered it: the in-flight open's bytes were lost and every
queued restore prompt stalled for the session. on_open_file now
refuses while an open is running (web only).
Hardening:
- Escape on the Recover Drawing modal defers instead of deleting the
only snapshot; the Discard button still removes it.
- A cap-rejected restore enqueue warns in-app and re-offers the next
snapshot; the drop queue cap rises to 32.
- Exiting mid-round no longer races snapshot removals (deferrals are
drained, the sweep skips while a round is in flight); closing a tab
with "Don't save" now also removes its web snapshot; the snapshot
key derivation is shared via web_autosave_key.
- The plot-preview overlay no longer leaks a full PDF copy per preview
(the Download closure lives in a replaceable registry).
- A corrupt autosave index.json fails the round/boot instead of
silently resetting every row; plot pages with non-finite or non-
positive sheet dimensions error instead of emitting a NaN MediaBox.
- The drop filter accepts dot-less "DWG"/"dxf" names the worker
parses (same rsplit convention on both gates).
(cherry picked from commit 3eab00bfbf)
Ported onto main (#1717 review): the five standalone tests/*_redteam.rs
files stay out — no test target builds them and they exercised copies of
the functions rather than the code itself.
Second review pass found the restore marker matched WebFileOpened by
display name: any same-named open finishing while the recovered one
was still queued deleted the only copy. The snapshot key now travels
with the queued file (tagged queue entries), the marker records the
open id assigned at dispatch, and success, failure, and cancel all
match that id. Cancelling an unrelated open no longer clears a
pending restore marker.
Also: the boot scan removes dead index rows (missing or zero-byte
snapshot files) that no other path could discard, and the drop
listener install only latches when the listeners really registered.
(cherry picked from commit c8777a857b)
Review of the drop-open and autosave commits surfaced one blocker and
five majors; all are fixed here, and two claims in the autosave commit
message are corrected by this one: tab close does NOT clear a snapshot
(matches native .sv$ semantics — saving, restoring, discarding, exit,
and the capped boot scan do), and serialization runs on the main
thread between awaits, not off the paint path.
- The restore prompt can no longer appear with no entries (empty
"Recover Drawing" modal on every boot once the autosave dir exists).
- Restore no longer consumes the snapshot before the open succeeds:
the recovered drawing goes through the guarded drop queue, and the
snapshot is deleted only after the tab opens; cancel or parse
failure keeps the only copy.
- Saving during an autosave round defers its snapshot cleanup until
the round finishes, so a stale round can no longer resurrect a
snapshot newer than the save.
- The boot scan no longer deletes snapshots by mtime comparison
(re-opening a drawing refreshes the recent copy's mtime, which
silently destroyed wanted snapshots); GC is now a 16-entry cap with
oldest-first eviction.
- OPFS write failures abort the writable stream (a leaked lock could
stall the same-key writer and disable autosave for the session), and
DOMException errors now carry their name/message.
- Empty (crash-window) snapshots are never offered; an unreadable one
warns and stays discardable instead of looping forever.
- Drop-open polish: reads start inside the handler and complete in
drop order (legacy WebKit safety, deterministic multi-file order),
dragenter is canceled too, the install guard only latches on
success, non-drawing drops don't steal propagation, a lock-poison
panic can't cross into JS, and re-dropping an open drawing no
longer risks clobbering an in-flight open (it re-queues).
- The model-space sheet floor is per-axis (a thin 8x400 mm profile
keeps its length) and centers content on the enlarged page.
(cherry picked from commit 3edbc5b7c8)
STLOUT/STEPOUT wrote via std::fs and IMPORTOBJ read via std::fs, all
of which fail on wasm32. The export pickers now mirror the PDF path
(pick_*_owned returns a name-only PathBuf; the browser download names
the file) and the write tail swaps fs::write for sys::download_bytes.
OBJ import reads the picked file's bytes directly, like the web open
picker.
Opening by drag-and-drop was dead on the web build: winit never emits
FileDropped there. A wasm-gated io::web_drop module installs DOM
dragover/drop listeners, filters .dwg/.dxf, reads the File bytes
async, and queues them; the existing 50 ms PollWebControl tick drains
the queue into the same open path the picker uses (progress overlay,
recovery, OPFS recent cache).
Also floors the model-space plot sheet: extents smaller than 10 mm
(or the 0x0 paper a fresh unsaved drawing carries) now fall back to
the standard sheet instead of producing a ~3 pt page.
