The Node.js url.parse API (https://nodejs.org/api/url.html#urlparseurlstring-parsequerystring-slashesdenotehost)
is deprecated because it's prone to security issues (to the point that Node.js doesn't even publish CVEs for it anymore).
The official reccomendation is to instead use the global URL constructor, available both in Node.js and in browsers.
Node.js filesystem APIs accept URL objects as parameter, so this also avoids a few URL->filepath conversions.
This major version contains three breaking changes that impact us:
- The `product` option has been renamed to the more suitable `browser`.
- The `page.screenshot()` API returns a `Uint8Array` instead of a
`Buffer`, but since `pngjs` requires a `Buffer` object we need to do
the conversion using `Buffer.from()` before passing data to `pngjs`.
- The browser configuration should be set using a configuration file
instead of environment variables. Note that as a bonus this allows us
to remove the `cross-env` dependency since that was only used to set
the Puppeteer environment variable equally for all operating systems.
For more information about the changes between the old and new Puppeteer
versions refer to https://github.com/puppeteer/puppeteer/releases.
Given that we handle non-embedded Calibri fonts as "mapped to standard font", we really ought to be able to use the same glyph mapping as for an actual standard font.
Note that this actually improves consistency in the code, given how we already handle such fonts if they happen to be of the `CIDFontType2` type; see b47c7eca83/src/core/fonts.js (L1186-L1190)
This integration test fails intermittently because we cache the initial
total value to be able to compare it to the new total value at the end
of the test to check that it's different before doing the assertions.
However, this doesn't work as expected because the second `clearInput`
call triggers an intermediate total value calculation because it clicks
on another input field and that triggers a sandbox event.
This results in the `waitForFunction` calls always resolving immediately
and since we don't use other means of waiting until the calculation is
done (using e.g. `waitForSandboxTrip`) we basically rely on the time
between the final click and the assertions to be enough for the sandbox
to do its work. If it's is not done in that time, we do the assertions
with older values and that makes the test fail.
This commit fixes the issue by simply waiting for the total value to be
what we expect it to be. This requires less code, is more consistent
with the other integration tests and removes the possibility of doing
assertions against older values.
In PR #18574 setting `window.uiManager` was moved into the `src` folder
to avoid intermittent integration test failures because at the time we
lacked a way to register event listeners early (before PDF.js loads).
However, in PR #18617 this functionality got introduced, so we can now
use the new way of setting up the event bus in the tests to move this
back to the `test` folder again and to reduce the amount of test-only
code in the main codebase as discussed in PR #18574.
Partially reverts e037c5711d.
The function evaluateOnNewDocument in Puppeteer allow us to execute some js before the pdf.js one
is loaded.
It allows us to stub some setters before there are used and then set some event handlers very soon.
This patch allows embedders of PDF.js to provide custom match
logic for seaching in PDFs. This is done by subclassing the
PDFFindController class and overriding the `match` method.
`match` is called once per PDF page, receives as parameters the
search query, the page contents, and the page index, and returns
an array of { index, length } objects representing the search
results.
It looks like this has accidentally been copy/pasted from the
`Textfields and focus` block, which is the only one in which a test
actually uses it. We can therefore safely remove it from all other
blocks where no test uses it.
The `waitForClick` helper function is functionality-wise mostly a
reduced copy of the more generic `waitForEvent` helper function that
we use for other integration tests, so we can safely replace it to
reduce the amount of code.
Moreover, the `waitForClick` code is prone to intermittent failures
given recent assertion failures we have seen on the bots (one of them
is linked in #18396) while `waitForEvent` has recently been fixed to
avoid intermittent failures, so usiong it should also get rid of the
flakiness for these integration tests.
Added annotations could have some quadpoints (highlight, ink).
The isNumberArray check was returning false and consequently the annotation wasn't
printable.
The tests didn't catch this issue because the quadpoints were passed as Array.
So driver.js has been updated in order to pass them as Float32Array in order
to be in a situation similar to the real life one.
This is possible thanks to features, i.e. private fields and in particular static initialization blocks, that didn't exist back when we started using classes in the code-base.
The current error-messages also mention internal parameters, which an end-user obviously don't have to care about. So, let's try to avoid confusion here by only including the API parameters.
When selecting text, hovering over an element
causes all the text between (according the the dom
order) the current selection and that element to
be selected.
This means that when, while selecting, the cursor
moves over a link, all the text in the page gets
selected. Setting `user-select: none` on the link
annotations would improve the situation, but it
still makes it impossible to extend the selection
within a link without using Shift+arrows keys on
the keyboard.
This commit fixes the problem by setting
`pointer-events: none` on the `<section>`s in the
annotation layer while selecting some text. This
way, they are ignored for hit-testing and do not
affect selection.
It is still impossible to _start_ a selection
inside a link, as the link text is covered by the
link annotation.
Fixes#18266
According to the PDF specification these destinations should have a zoom parameter, which may however be `null`, but it shouldn't be omitted; please see https://opensource.adobe.com/dc-acrobat-sdk-docs/pdfstandards/PDF32000_2008.pdf#G11.2095870
Hence we try to work-around bad PDF generators by making the zoom parameter optional when validating explicit destinations in both the worker and the viewer.
As far as I can tell `Outliner` is only exposed in the API because we need to access it when running some of the reference-tests, but is otherwise not used.
Hence this seems like something that should be kept *internal* and thus only exposed in TESTING-builds.
Switching to an editing mode can be asynchronous (e.g. if an editable annotation exists on a
visible page), so we must add a new editor only when the page rendering is done.
In PR #18356 the new tab page logic was disabled to prevent Firefox
from logging failed network connections to Contile, the Mozilla Tiles
service that is used for the new tab page [1]. However, recently this
log reappeared locally and on the bots:
```
console.warn: TopSitesFeed: Failed to fetch data from Contile server:
NetworkError when attempting to fetch resource.
```
It looks like Contile communication is also triggered from other places
in Firefox such as the URL bar [2], so this commit fixes the issue by
disabling network connections to Contile [3] altogether regardless of
their origin within Firefox. Note that we don't revert the change from
PR #18356 because as noted in [4] it can't hurt to keep that disabled
too to avoid overhead for a feature we don't use in the tests.

When the mouse was hovering an existing highlight, all the text in the page
was selected.
So when the user is selecting some text or drawing a free highlight, the mouse
is disabled for the existing editors.
Because of editor z-index, the toolbar belonging to an highlight created
before a second adjacent one, can be overlapped by this new one.
So when the user select an editor we just show it on front of all the other
ones to make sure that it can be used normally.
This functionality is purposely limited to development mode and GENERIC builds, since it's unnecessary in e.g. the *built-in* Firefox PDF Viewer, and will only be used when a `<base>`-element is actually present.
*Please note:* We also have tests in mozilla-central that will *indirectly* ensure that relative filter-URLs work as intended in the Firefox PDF Viewer, see https://searchfox.org/mozilla-central/source/toolkit/components/pdfjs/test/browser_pdfjs_filters.js
