When an editor is moved with the keyboard or in dragging it, it is moved in the DOM in order
to make screen readers happy. But this move is slightly postponed thanks to a setTimeout(..., 0).
The failures were very likely due to the fact that intermittently the DOM move was done in
the middle of the next key sequence which was making the move on screen failing.
It was due the resize observer which is removed thanks to this patch.
In order to reuse the dragAndDrop function in test, this patch slighty refactors it
in order to make it easier to use.
The `must check input for US zip format` integration test fails pretty
consistently in Puppeteer 23.4.0+ with `Expected '12341' to equal
'12345'`. This is reproducible with the `pdf.sandbox.external.js` hack
from https://github.com/mozilla/pdf.js/issues/18396#issuecomment-2211273743.
Investigation uncovered two issues at play here:
1. We do two `clearInput` calls, but don't await processing of the two
sandbox events that are triggered by that action. The three tests that
use `issue14307.pdf` are in different `describe` blocks and therefore
reload the PDF file, so we can simply remove those calls because the
inputs are already empty by default.
2. We don't await processing of the sandbox events that occur after
switching to another text field. This causes the expectation failure
because the typing actions will happen too soon and interfere with
the sandbox event processing. We solve the issue by explicitly
awaiting the sandbox roundtrip.
Moreover, similar to PR #19001 and #18399 we remove any remaining room
for intermittent issues by directly checking for the expected value,
which also results in shorter code.
Converting errors to string drops their stack trace, making it more
difficult to debug their actual reason. We can instead pass the error
objects as-is to console.warn/error, so that Firefox/Chrome devtools
will show both the stack trace of the console.warn/error call, and the
original stack trace of the error.
This commit also enables the `unicorn/no-console-spaces` ESLint rule,
which avoids accidental extra spaces when passing multiple parameters to
`console.*` methods.
Some tests rely on the presence of a server that serves PDF files.
When tests are run from a web browser, the test files and PDF files are
served by the same server (WebServer), but in Node.js that server is not
around.
Currently, the tests that depend on it start a minimal Node.js server
that re-implements part of the functionality from WebServer.
To avoid code duplication when tests depend on more complex behaviors,
this patch replaces createTemporaryNodeServer with the existing
WebServer, wrapped in a new test utility that has the same interface in
Node.js and non-Node.js environments (=TestPdfsServer).
This patch has been tested by running the refactored tests in the
following three configurations:
1. From the browser:
- http://localhost:8888/test/unit/unit_test.html?spec=api
- http://localhost:8888/test/unit/unit_test.html?spec=fetch_stream
2. Run specific tests directly with jasmine without legacy bundling:
`JASMINE_CONFIG_PATH=test/unit/clitests.json ./node_modules/.bin/jasmine --filter='^api|^fetch_stream'`
3. `gulp unittestcli`
The date was create in UTC+0 and then amended in using set-Month/Date which take into account
the user timezone.
With this patch we build all the date in the user timezone.
This patch makes a clear separation between the way to draw and the editing stuff.
It adds a class DrawEditor which should be extended in order to create new drawing tools.
As an example, the ink tool has been rewritten in order to use it.
Given that `browsertest` repeatedly timeout in Google Chrome, and considering that Firefox is the primary development target, we stop running them on the bots to avoid having to repeatedly deal with this.
Note that we already disabled these tests *on Windows* almost three years ago, because of stability issues; see PR 14392.
test/unit/api_spec.js is the only JS file in the tree with trailing
whitespace. Because `trim_trailing_whitespace = true` in .editorconfig,
any editor supporting EditorConfig would trim whitespace when the file
is changed, which results in test failures.
This commit fixes the issue by trimming the trailing whitespace and
adjusting the test expectations.
The following cases are excluded in the patch:
- The Firefox PDF Viewer, since it has been fixed on the platform side already; please see https://bugzilla.mozilla.org/show_bug.cgi?id=1683940
- The `PDFNodeStream`-implementation, used in Node.js environments, since after recent changes that code only supports `file://`-URLs.
Also updates the `PDFNetworkStreamFullRequestReader.read`-method to await the headers before returning any data, similar to the implementation in `src/display/fetch_stream.js`.
*Note:* The relevant unit-tests are updated to await the `headersReady` Promise before dispatching range requests, since that's consistent with the actual usage in the `src/`-folder.
The test-only createTemporaryNodeServer helper featured a path traversal
vulnerability. This enables attackers with network access to the device
to read arbitrary files while unit tests are running that activate this
test server.
This patch fixes the issue by validation of paths.
To test this vulnerability before the patch:
1. Run the test-only server:
```
node -e 'console.log(require("./test/unit/test_utils.js").createTemporaryNodeServer().port)
```
2. From another terminal, send the following request (modify the port to
the port reported in the previous step):
```
curl --path-as-is http://localhost:45755/../../package.json
```
Before the patch, the second step would traverse the directory, and
return results from the root of the PDF.js repository, instead of files
within test/pdfs/.
With the patch, the server refuses the request with HTTP status 400.
