Clean Up removes named destinations that nothing in the document refers
to. referenced_names counted the /D of GoTo, GoToR and GoToE actions
alike. The /D of a GoToR or GoToE action names a destination in another
document, so a local destination with the same name was kept although
nothing in the document used it.
Only a GoTo's /D now counts as a use. A /Dest key and a GoTo's /D are
read as before.
Test: links with a GoTo, a GoToR and a GoToE action name three
destinations; optimize() keeps the one the GoTo uses and removes the
other two.
content_draws tells whether some content draws an XObject, directly or
through a form that has no /Resources of its own and so draws through
its caller's. Since #4356 the recursion passed the caller's content
again instead of the nested form's decoded data, so a name drawn only
inside such a form was never found.
Both callers then dropped the entry: unlink_doomed for page-tree
resources (Apply Redactions and the content pass of Remove Hidden
Information) and prune_doomed_xobjects for surviving forms. An image
removed under a mark but still shown elsewhere through such a form went
missing from there as well.
The recursion reads the nested form's data again, as it did before
#4356. Two tests cover the page-tree case and the surviving-form case.
Both fail without the fix.
hayro-cmap reads CMap streams with hayro-postscript's token scanner,
whose object::read skipped each `<<` and `>>` by calling itself again.
A CMap holding a long run of `<` or `>` used one stack frame per pair,
overflowed the stack and aborted the process.
Vendor hayro-postscript 0.1.0 with read() looping over the delimiters
instead (from storytold/craft-libs#263), patched in beside hayro-cmap.
Four object::tests cover long `<<` and `>>` runs and the skipped
delimiters, plain and nested.
TextBox::fits checked only the height of a wrapped multi-line value.
Long words break by character, so a single character wider than the
box still overflows it, and the appearance reports Overflow::Wide for
a value fits had accepted. The multi-line branch now also requires
every wrapped line to fit the width.
Editing a large comment whose top-right corner was scrolled away opened a composer that was hidden and could not be cancelled. The card now stays, clamped into the document, while any part of the comment shows.
#3670 raised the form depth limit to 50 and added its own 50,000-visit cap. Main's
per-page DecodeBudget (e2a677164) has the same 50,000-form limit, and the visit cap
fired first, so Apply removed the forms instead of refusing the page as main does.
The visit cap goes; the fan-out test expects the refusal, and the depth-limit
sanitization test builds its chain from MAX_DEPTH.
Session::refresh_with_indexes fills title, author and the other fields from XMP as build_document does; the test applies an edit and an undo and checks they stay.
ROADMAP.md: kept both progress lines.
crates/optimize/README.md: PR's decoder sentence plus the target-version section from main.
Cargo.lock: auto-merged.
crates/ui-egui/src/ocr_ui.rs: kept both sides in poll_ocr (poisoned-lock handling plus the automatic-run wait) and in the test module (one mod, both sets of tests); the 4196 test literal gets automatic: None.
