Currently the transfers aren't actually being used with the "GetOperatorList" message, since the placement of the parameter is wrong; note the method signature: 909a700afa/src/shared/message_handler.js (L219-L229)
This goes back to PR 16588, which added the transfers parameter, and unfortunately we all missed that :-(
Simply fixing the parameter isn't enough however, since that broke printing of Stamp-editors (and possibly others). The solution here is to *not* transfer data during printing, given that a single `PrintAnnotationStorage` instance is being used for all pages.
It fixes#20715.
`failedExpectations` was removed from `suiteStarted` and `specStarted` events.
HtmlReporter and HtmlSpecFilter have been deprecated and removed.
Change all these cases to use `Map.prototype.getOrInsertComputed()` instead, in combination with a helper function for creating the `Array`s (similar to the previous patch).
With the exception of the first invocation the callback function is unused, which means that a lot of pointless functions may be created.
To avoid this we introduce helper functions for simple cases, such as creating `Map`s and `Objects`s.
In all cases where we currently use `Response.prototype.arrayBuffer()` the result is immediately wrapped in a `Uint8Array`, which can be avoided by instead using the newer `Response.prototype.bytes()` method; see https://developer.mozilla.org/en-US/docs/Web/API/Response/bytes
We tried to lookup the font metrics using the font name as-is, which didn't work since the PDF file in question has non-embedded fonts with names that include commas.
Hence the font names need to be normalized here as well, similar to elsewhere in the font code.
Report loading progress "automatically" when using the `PDFDataTransportStream` class, and remove the `PDFDataRangeTransport.prototype.onDataProgress` method
Currently this code expects a "url string", rather than a proper `URL` instance, which seems completely unnecessary now. The explanation for this is, as so often is the case, "historical reasons" since a lot of this code predates the general availability of `URL`.
This is consistent with the other `BasePDFStream` implementations, and simplifies the API surface of the `PDFDataRangeTransport` class (note the changes in the viewer).
Given that the `onDataProgress` method was changed to a no-op this won't affect third-party users, assuming there even are any since this code was written specifically for the Firefox PDF Viewer.
This should help reduce the maintenance burden of the code, since you no longer need to remember to update separate code when touching the different page/thumbnail classes.
