We can remove most feature testing from this helper function, with the exception of `randomUUID` since that's only available in "secure contexts", and also remove the fallback code-path.
Note that this code was only added for Node.js compatibility, and it's no longer necessary now that the minimum support version is `20`; see also https://developer.mozilla.org/en-US/docs/Web/API/Crypto#browser_compatibility
Finally, this patch also adds a basic unit-test for the helper function.
JSON imports are now supported by all tools used in PDF.js' build
process. The `chromecom.js` file is bundled by webpack and
import attributes are thus removed, so browser compatibility for this
new syntax is not relevant.
This integration test fails intermittently, locally at least in Chrome
with Puppeteer 23.4.0+, with the following errors:
```
In chrome: Expected '123Hello' to equal 'Hello123'.
In chrome: Expected '123Hello' to equal '123'.
```
This happens because the test before it left queued sandbox events
behind. We don't close the document between tests, so those get run
when we click the textbox in this test and that interferes with our
selection/typing actions. This commit fixes the issue by flushing the
queued sandbox events in the first test, which makes sure that state
no longer leaks through to the next test and thus improves isolation.
Morever, similar to commit 3adf8b6 we use safer assertions to avoid
further intermittent failures, and we replace the `page.$eval` call
with a simpler Home button push like we already do in e.g. the test
helpers. This combined makes the code shorter and simpler.
In PR #11300 Gitpod support got introduced, but we re-evaluated that
decision in #11732. In PR #11800 the support was partially reverted,
but the actual Gitpod files were kept to not outright break potential
workflows because at the time we were not sure if, and if so how often,
Gitpod was actually used for contributing to PDF.js.
However, in addition to the concerns mentioned in #11732 after five
years we haven't seen any contributions that clearly originated from
Gitpod, and the files have not been updated after e.g. PR #11807 and
PR #17913 because it's not a workflow that we maintain or are able
to test (nor have we seen Gitpod community contributions for this).
This commit therefore removes the remaining Gitpod files to reduce
maintainance burden for PDF.js. Note that users of Gitpod can still
contribute to PDF.js via the platform; we just don't provide/manage
workspace files from this repository anymore.
- Use optional chaining when clearing various data-structures, since that's slightly shorter.
- Ensure that checking for the existence of `#_hcmCache`-data won't cause it to be initialized. (Note how `this.#hcmCache` is actually a getter.)
- Actually reset the `#_hcmCache`-data when that's appropriate, e.g. when closing the PDF document.
- Ensure that `pdfjsTestingUtils` is available when running benchmarking, since that shouldn't be done in TESTING-mode.
- Exclude the `test/stats/results/` folder from linting, since it'll contain *generated* JSON-files.
When iterating through `useCMap` the value is already available, without having to manually invoke the `lookup`-method.
While this will likely not affect performance in any noticeable way, it's nonetheless unnecessary to lookup an already available value twice.
This was previously attempted in PR 13371, but had to be reverted because of issues related to SystemJS (which has since been removed).
Also, while unrelated, shortens an existing conditional assignment.
The purpose of these changes is to make it more difficult to accidentally include logging statements, used during development and debugging, when submitting patches for review.
For (almost) all code residing in the `src/` folder we should use our existing helper functions to ensure that all logging can be controlled via the `verbosity` API-option.
For the `test/unit/` respectively `test/integration/` folders we shouldn't need any "normal" logging, but it should be OK to print the *occasional* warning/error message.

Given that there are multiple issues with `ImageDecoder` in Chromium browsers, affecting both BMP and JPEG images, for now we (by default) disable that functionality there to avoid problems.
This also means that we can remove the previously added, and separate, `isChrome` API-option.
Python 3.13 is the current version and was released over a month ago
(see https://devguide.python.org/versions). The dependencies we use now
support Python 3.13, most importantly `fonttools` which uses OS-specific
builds and for which compatibility got introduced in
https://github.com/fonttools/fonttools/pull/3656 and the corresponding
`cp313` wheels for all distributions are published on
https://pypi.org/project/fonttools/#files.
Moreover, we fix forgotten `npx` usage in the font tests README which
was encountered while testing this patch.
This is unblocked now that all dependencies have been updated and the
flat configuration format (compatible with ESLint 8 and 9) was
introduced first. The following deprecation warnings during `npm
install` are resolved by this upgrade:
```
npm warn deprecated @humanwhocodes/config-array@0.13.0: Use @eslint/config-array instead
npm warn deprecated @humanwhocodes/object-schema@2.0.3: Use @eslint/object-schema instead
npm warn deprecated eslint@8.57.1: This version is no longer supported. Please see https://eslint.org/version-support for other options.
```
Note that according to https://eslint.org/version-support ESLint 8 is
officially EOL now, and ESLint 9 has been released for over seven
months and is the only officially supported version.
Fixes#17928.
This allows end-users to forcibly disable `ImageDecoder` usage, even if the browser appears to support it (similar to the pre-existing option for `OffscreenCanvas`).
Flat config is the new config system used by ESLint 9.
To make the migration easier, they also added
flat config support to ESLint 8.
This commit migrates the various ESLint configs in the repository to use
the new system, **without** upgrading to ESLint 9 yet.
