This PR is related to GH-20732, which is about `AuthEvent` (to delay
promting for a password), but instead adds the actual support for
encrypted attachments.
“Encrypted attachments” means that the main things are plain text.
Note that some PDF viewers, like Preview/QuickLook/Safari or Chrome,
do not support attachments at all.
Note that the file checked into the tests is the same as
`output-no-auth-event.pdf` referenced in
<https://github.com/mozilla/pdf.js/issues/20139#issuecomment-3952462166>.
Closes GH-20139.
I happened to notice that the way the `OptionalContentConfig`-data handled in the PR that implements worker-rendering leaves a lot to be desired:
- The way that the optional content state is handled is not correct, since that PR collects the "effective visibility" of the optional content groups rather than their *actual* internal state.
- The necessary `OptionalContentConfig`-data is collected piecemeal in the API, which leads to quite frankly very messy code that's hard to read and will be even harder to maintain.
The solution to all of these issues seem really simple though, just add a couple of `OptionalContentConfig` methods that serialize/de-serialize the necessary data.
In the API calling `optionalContentConfig.serializable` will get *all* of the needed data for transferring to the worker-renderer, and once received there calling `OptionalContentConfig.fromSerializable(/* transferred data here */)` will create an `OptionalContentConfig` instance with the correct internal state.
As part of this patch, to avoid increasing bundle-size unnecessarily, a couple of existing methods are stubbed out when the `OptionalContentConfig` class ends up in a worker-file (since they're unused there).
This part assumes that the new worker-renderer is built correctly, note how the existing `pdf.worker.mjs` is handled in 03eda70d7e/gulpfile.mjs (L539-L545)
(*Note:* Submitting a PR was a lot faster than trying to provide review comments, since writing this commit message took longer than writing the patch.)
Fonts that ship a BlueScale outside the range AFDKO considers valid
for their zone heights (0.5/maxZoneHeight <= BlueScale <= 1/maxZoneHeight)
cause Firefox's CFF rasterizer to misalign overshooting glyphs against
flat-topped ones at body sizes.
Clamp into that window, only apply the lower clamp when BlueScale is
also smaller than the default, so foundry fonts that pair the default
0.039625 with small zones are untouched.
Fixes#9437.
It fixes#15292.
PDFs can embed a CID-keyed Type 1 program (Adobe TechNote 5014,
CIDFontType 0) under /Subtype /CIDFontType0 + /FontFile. Its binary
CIDMap/SubrMap layout has no eexec block, so Type1Font's eexec-only
parser used to fall through and trigger the work-around added in
PR #15397.
Split the constructor and parse the binary CIDMap, SubrMap
and charstrings (encrypted with the standard Type 1 charstring cipher)
through the existing Type1CharString.convert + CFF wrap pipeline.
Only single-FDArray fonts are supported; the StartData length is
clamped to the stream's remaining bytes before allocating.
- functions were already removed
- variables can be removed when their initializer does not have side effects
- classes can be removed when they have no static blocks
Fixes#21337
Given that changes to either the Babel plugin or the "old" builder could accidentally cause issues in the built files, it seems like a good idea to run all test-suites when the `external/builder/` folder is changed.
When a reftest hangs and trips the per-browser timeout, the session was
closed, which left every remaining task in the per-browserType queue with
no consumer and effectively skipped the rest of the manifest. Instead,
mark the in-flight task(s) as failed, reload the page so the driver can
reconnect and request the next task, and only fall back to closing the
session if the reload itself fails.
Adds a `postMessageAfterPrintCallback` browser option (off by default).
When enabled by Firefox, the print service posts "ready" or "error" to
the window after each page's mozPrintCallback resolves, so embedders
(e.g. print-preview test harnesses) can observe when rendering is done.

Enable the recommended preset and fix or per-line-disable the 78
findings it surfaces. Most are equivalent rewrites, intentional
patterns (control chars, the whatwg email regex, autolinker URL regex)
keep their behavior via targeted disables.
Fixes#21259.
Reset letter-spacing and word-spacing on the text layer and hidden measurement canvas so inherited page styles do not affect text layer alignment. Add an integration regression test for inherited spacing.
This patch is generated automatically using `npm audit fix`, and brings
the number of reported vulnerabilities back to zero by patching:
- GHSA-jxxr-4gwj-5jf2: "brace-expansion: Large numeric range defeats
documented `max` DoS protection"
- GHSA-58qx-3vcg-4xpx: "ws: Uninitialized memory disclosure"
It fixes#7625.
If the Top DICT's Private DICT extends past the end of the font data,
the Local Subrs INDEX is unreachable and every CharString that calls
a subr ends up as a blank glyph. Throw from parsePrivateDict so the
existing catch in translateFont triggers fallbackToSystemFont, then
run getFontSubstitution post-construction so we pick a close local
match instead of the generic fallbackName.
Some Type1 fonts (the embedded Optima variants in orw1972.pdf) ship
two /Subrs and /CharStrings blocks wrapped in save/restore frames
gated on an Adobe hires/lores runtime switch.
In such cases, we just use the first /Subrs and /CharStrings block,
which is the one that is actually used by the font renderer in Acrobat.
It fixes#18548.
In many/most PDF documents every glyph will require that the character BBox has scaling/offset applied, which can be made a tiny bit more efficient. In particular:
- Avoid creating one additional temporary Array for every glyph.
- Simplify the helper function, since there's no skew-components.
