Add the linesweeper 0.5.0 package to vendor/ with no file changed, so
that a fix to it can reach the Craft apps through this repository
without waiting for a linesweeper release. The GitHub repository its
manifest names is archived, and its README says development moved off
GitHub.
Leave out the test font (fonts live in craft-fonts), the logo artwork,
the snapshot images and the package's repository tooling. SOURCE.json
lists each with its hash.
Add a workspace exclude, a [patch.crates-io] entry, SOURCE.json with
the archive hash and per-file hashes, NOTICE and ATTRIBUTION.md rows,
and the package's tests in the backend test script. craft-prepress's
flatten feature now builds against the copy, so Cargo.lock drops the
package's registry source and checksum.
hayro-postscript 0.1.0 is the token scanner hayro-cmap uses for the
CMap streams PDFs embed. Its object reader skipped each `<<` or `>>`
by calling itself again, so a stream holding a long run of `<` or `>`
bytes recursed once per pair and aborted the process with a stack
overflow.
Vendor the crates.io package unchanged and patch `object::read` to
skip those runs in a loop, returning the same next object as before.
Wire it in like the other Hayro crates: workspace exclude,
[patch.crates-io] entry, SOURCE.json with registry and local hashes,
the backend test script, NOTICE, ATTRIBUTION.md and the reader README.
Tests cover a million `<` and a million `>` bytes, `<< /A 1 >>` and
nested `<<<< /X >>>>` runs.
* pdf: keep a CID font's /W2 table past an out-of-range first CID; vendor hayro-cmap from PdfCraft
- hayro-interpret: a /W2 run whose first CID is past 65535 is skipped, as in
/W. A run starting at 4294967295 overflowed the CID counter and discarded
the whole table. Unit test in font::cid.
- hayro-cmap 0.1.0 is vendored from PdfCraft a2ec27b47 with its malformed-CMap
patch (PdfCraft #3177): bad bfchar/bfrange entries, an unresolvable usecmap
and an unparseable tail are skipped instead of failing the whole CMap. The
crate's tests come with it. Wired up like the other vendored Hayro crates
(workspace exclude, patch entry, SOURCE.json, backend test script); NOTICE,
ATTRIBUTION.md and vendor/README.craft-reader.md record the source.
* hayro-syntax: refuse an xref-stream subsection that runs past object number u32::MAX
The object number was start + i in unchecked u32: a subsection starting near
u32::MAX overflowed (a panic in debug builds, a wrong object number in
release). Covered in xref::tests::xref_stream_entries_need_backing_bytes.
* hayro-cmap: a binary usecmap counts against the nesting limit; /W2 checks the CID first
- hayro-cmap: a binary CMap's usecmap passed its own depth to the nested
parse, so a self-referencing binary CMap recursed until the stack
overflowed. It now counts like a text usecmap. Test:
self_referencing_binary_usecmap_stops_at_the_nesting_limit.
- hayro-interpret: the /W2 first-CID check runs before the run's metrics
are read, so an incomplete run past CID 65535 no longer discards the
rest of the table.
* hayro-syntax: refuse xref-stream object numbers past i32::MAX
ObjectIdentifier stores an i32; a number between i32::MAX and u32::MAX
was cast to a negative object number.
