Android Crash shaders/ink_sparkle.frag #139

Closed ThomasAunvik closed 3 weeks ago

ThomasAunvik commented 3 weeks ago

This might be an issue with flutter itself https://github.com/flutter/flutter/issues/143806 , reported to this repo since this plugin has that issue when i used it.

Tested with and without impeller.

Also tested on the master branch of flutter, same issue.

So, I now tested with the master branch a bit further, and added some prints between FPDF_LoadPage calls.

https://github.com/espresso3389/pdfrx/blob/5717726e31dbfcaee7bba0d332c260ab62d7a095/lib/src/pdfium/pdfrx_pdfium.dart#L358-L362

I don't know if its just the pdf files i have, the way i load them or etc. I use PdfViewer.data() , to show the pdf files.

I tested this first on pdfium chromium/6259 (which is what currently is on master), and tested it also with the latest version chromium/6406

In one instance I believe, it failed to render due to an invalid glyph? And then i tried using an almost empty pdf.

And sometimes it would be able to render a few pages in a short second, and then crashes.

Maybe one suggests it could be a concurrency issue? Idk if that is what is used in this project? https://stackoverflow.com/a/64653357

Basically, on pdfrx architecture, worker.compute ensures only one API call is invoked at same time. No concurrency issues if worker.compute has no bug.

And the code there is straight enough, just calling FPDF_LoadPage, FPDF_GetPageWidthF, FPDF_GetPageHeightF, FPDFPage_GetRotation, and FPDF_ClosePage. No tricky code there.

I have no idea what's wrong...

ThomasAunvik commented 3 weeks ago

Could also to see with the render function? I think at least some errors at that same FPDF_LoadPage? Bit weird, i do able to see first pages of the pdf, and then crashes after a second, or immidiately.

https://github.com/espresso3389/pdfrx/blob/5717726e31dbfcaee7bba0d332c260ab62d7a095/lib/src/pdfium/pdfrx_pdfium.dart#L578-L580

espresso3389 commented 3 weeks ago

Every function that calls FPDF_LoadPage including render function uses document._worker.compute so that every the function call is blocked each other. In theory, it does not cause any race condition issues.

By the way, what device do you just now? Is the issue is fully producible on every device?

ThomasAunvik commented 3 weeks ago

I use a Samsung S23+ SM-S916B/DS Android Version 14.

I'll have to test later tomorrow on emulators if I have the same issues there.

And see if I can make an example reproducible.

ThomasAunvik commented 3 weeks ago

Ok, so i found out why i was crashing. And it's pretty stupid of me to now realize why i did it.

I called PdfDocument.openData (without await) (to be used as a future later on if i wanted to have a page specific view) and then used PdfViewer.data to view the whole pdf.

Not sure exactly what caused it in totality, but my class consisted of this basically.

Widget build(BuildContext context) {
    if (mobile) {
      return PdfViewer.data(document.data, sourceName: "memreport");;
    }

   return FutureBuilder<PdfDocument>(
        future: document.pdfdoc,
}

removed the extra PdfDocument.openData and the bottom part to only use pdfviewer fixed it.
