We currently download Chrome/Firefox immediately on `npm install`
invocations because Puppeteer's postinstall script does that by default.
However, this is wasteful if the user/workflow doesn't actually need to
run Puppeteer or its browsers, for example in GitHub Actions workflows
that do linting, static analysis or other tasks like updating locales or
publishing artifacts.
This commit therefore makes sure no browser binaries get pulled in by
default anymore, and defers doing that until it's actually necessary,
which is when we want to start the browsers in the `startBrowsers`
function of `test.mjs`.
Locally this brings the `npm install` runtime down from 8.998 to 1.800
seconds, and as a bonus it results in better log output too because it
now shows which browser versions were used in the run (whereas
previously with `npm install` this information was not sent to stdout).
We currently use the pinned version of Chrome as hardcoded in the
Puppeteer release, which is based on the version of Chrome that was
deemed stable at the time of the Puppeteer release.
However, this is not ideal because it means that Chrome updates are
strongly tied to Puppeteer releases, so if Puppeteer releases are slow
we could be missing out on e.g. (security) patches being applied on the
stable channel. It's also not consistent with Firefox where we don't
use a hardcoded pinned version either.
This commit therefore configures Puppeteer to use (resolve) the most
recent stable version of Chrome at the time of the installation so that
determining the browser version to use is fully decoupled from the
Puppeteer release we're running.
The effect of this change can be seen in the output of running
`npx puppeteer browsers list`:
Before:
`chrome@149.0.7827.22 (linux) <path>`
After (note the slightly newer version):
`chrome@149.0.7827.115 (linux)` <path>`
Nowadays Chrome has a built-in (new) headless mode in the regular
binary, but before that time there was an old headless mode that was
essentially a separate binary [1]. We don't use the latter, but it turns
out that Puppeteer downloads it automatically if it's not explicitly
skipped, which is wasteful because it costs extra time and resources for
each `npm install` invocation.
This commit therefore skips downloading Chrome headless shell explictly,
which results in the local runtime of `npm install` going from 10.125
seconds to 8.998 seconds (which can't hurt in e.g. GitHub Actions).

The "Merge PDF" integration-tests will (indirectly) invoke `PDFViewerApplication.open` as part of loading the new PDF document, which will end up creating a new `PDFWorker` instance.
Currently worker coverage is only collected at the end of each integration-test, which means that in these cases we miss the coverage data from any "previous" workers.
Currently when opening a PDF document the following code is used, where `checkFirstPage`/`checkLastPage` helps detect XRef corruption; note 86a18bd5fe/src/core/worker.js (L167-L176)
However when merging a PDF into an existing document the parsing is only "partial"; note 86a18bd5fe/src/core/worker.js (L632-L634)
It seems a little strange to not support corrupt PDFs in a consistent manner in the code-base, hence this patch adds a new `BasePdfManager` helper that handles all the relevant parsing/checking and re-uses that when merging PDFs.
We use the generic `page.mouse.move(x, y, { steps }` API, but that purely
performs the mouse move steps without having knowledge about if/how the
application handles any events caused by it, so it doesn't wait for the
sidebar to render before moving on. This causes intermittent failures if
the sidebar didn't get enough time to render before the next mouse move
is initiated (which can happen in slower environments).
This commit fixes the issue by doing the mouse move steps ourselves and
by waiting for a browser trip between each of them to make sure that the
sidebar got a chance to render.
Fixes#21447.
Relates to #21044 / #21045 / 24e5377.
This is a major version bump, but the changelog at
https://github.com/sindresorhus/eslint-plugin-unicorn/releases/tag/v65.0.0
doesn't indicate any breaking changes that should impact us.
However, there is one false positive, possibly introduced by patch
https://github.com/sindresorhus/eslint-plugin-unicorn/pull/3028:
```
src/core/xfa/factory.js
104:54 error Prefer `.some(…)` over `.find(…)` unicorn/prefer-array-some
```
This is incorrect because on this line we're not dealing with an array
but with a `FontFinder` instance instead (and that doesn't have a
`.some()` method), so we ignore the rule for this line.
This removes a little bit of code duplication, which only exist since the `src/display/canvas.js` code pre-dates the helper function by many years.
Note: Given that `OffscreenCanvas` is enabled by default there's currently not a lot of test coverage for this code-path, hence the added browser-test.
This functionality was added specifically for the standalone image-decoders, and by utilizing the pre-processor we can reduce the amount of "unnecessary" code in the regular builds.
Also, shorten a few loop variables a little bit since less code is always good.
The idea is to generate two operator lists for the Yes/Off states and render them on a separate canvas.
These canvases are then attached the annotation and we modify their display depending on the input state.
It fixes#18021.
This basically extends PR 9549 to the fallback `getAllPageDicts` method, which didn't exist at the time, in order to support more cases of corrupt PDF documents.
Currently the same code, for requesting the password from the main-thread, is now duplicated three times.
Let's avoid that by moving the new `getPassword` helper function, added in the previous commit, and re-use that everywhere instead.
These unit-tests used a PDF that prompted for password on document load, which meant that the on-demand password handling wasn't actually being tested as intended.
Updating the unit-tests also caused the "re-prompts for encrypted attachments after incorrect passwords" test to fail, since the `INCORRECT_PASSWORD` password reason was being accidentally "swallowed" in the worker-thread.
This removes a little bit of code duplication, which only exist since the `src/display/canvas.js` code pre-dates the helper function by many years.
*Note:* Given that `OffscreenCanvas` is enabled by default there's currently not a lot of test coverage for this code-path, hence the added browser-test.
This method has been completely unused for many years, possibly as far back as PR 8030, hence we can avoid shipping a little bit of dead code.
*Note:* If there's any third-party code depending on it, updating it ought to be as simple as changing
```javascript
const r = viewport.convertToViewportRectangle(rect);
```
into
```javascript
const r = [
...viewport.convertToViewportPoint(rect[0], rect[1]),
...viewport.convertToViewportPoint(rect[2], rect[3])
];
```
Center each glyph within its comb cell instead of left-aligning it,
both in the HTML annotation layer and in the printed/saved appearance,
to match Acrobat. Cell width is now the single source of truth via the
--comb-width CSS variable, and field text-alignment (center/right) is
applied as a whole-cell --comb-offset that stays in sync on input,
blur, resetform and updatefromsandbox. The field no longer grows on
focus; trailing letter-spacing is clipped and cell dividers are drawn
on focus.
The print service injected the per-PDF `@page { size }` rule as an inline
<style> element, which required 'unsafe-inline' on style-src-elem.
Inject it through a constructable CSSStyleSheet attached to
document.adoptedStyleSheets instead. Constructable stylesheets aren't
subject to style-src's inline restrictions in browsers.
