The default `page.type()` API from Puppeteer works for text fields that
only dispatch a sandbox event on e.g. focus loss (i.e. after all
characters have been inserted), and for those we can also use the
default typing delay from Puppeteer instead of defining our own value.
However, it doesn't work correctly for text fields where every character
insertion dispatches a sandbox event. This is because processing the
sandbox event takes some time and Puppeteer must wait for that before it
can (safely) insert the next character. This commit therefore introduces
a helper function to type a given value correctly in such text fields.
Not only does this fix intermittent failures if our delay was too low
for sandbox processing to complete, but it also speeds up the tests by
eliminating our delays in places where they were (much) higher than
necessary. In total the runtime of the scripting integration test suite
goes from 137 seconds before this patch to 100 seconds after this patch.
It fixes#18849.
When such an annotation is deleted, we make sure that there are some data
to restore.
The version of this patch was making undoing a svg deletion buggy, so it's fixed now and
an integration test has been added for this case.
The first goal of this patch was to remove the tabindex because it helps
to improve overall a11y. That led to move some html elements associated
with the buttons which helped to position these elements relatively to their
buttons.
Consequently it was easy to change the toolbar height (configurable in Firefox
with the pref browser.uidensity): it's the second goal of this patch.
For a11y reasons we want to be able to change the height of the toolbar to make
the buttons larger.
The idea is to insert a span in the text layer with an aria-role set to img
and use the bounding box provided by the attribute field in the tag dict in
order to have non-null dimensions for the image to make it "visible".
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.

versions refer to https://github.com/puppeteer/puppeteer/releases.
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 e037c5711d3d2413669e9b6c275986adf24a295b.
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.
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.
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
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.
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.
Code inspection uncovered that quite a few integration tests don't wait
for scripting to be ready before proceeding, which is a source of
intermittent failures, especially on slower machines where e.g. creating
the sandbox takes longer.
This commit fixes the issues by introducing a `waitForScripting` helper
function and calling it consistently in all scripting integration tests.
This integration test fails intermittently because we're not (correctly)
awaiting the character limit increase sandbox action.
For the first increase an attempt was made to handle this, but it doesn't
work correctly because the text in the field is `abcdefghijklmnopq` and
it's not be truncated until the sandbox action is completed, so because
we didn't await that we would could pass the `value !== "abcdefgh"` check
because `abcdefghijklmnopq !== abcdefgh` is true. For the second increase
we didn't have a check in place.
This commit fixes the issues by using the `waitForSandboxTrip` and
`waitForSelector` helper functions to make sure that we can only proceed
if the sandbox action is completed and the DOM element is updated.
