Description Alberto Salvia Novella 2019-12-07 15:33:24 UTC
- Export a moderately large document as EPUB (a document of 300MB is enough)

- The save dialogue hangs.
- The hole system drastically slows down.

- The conversion process should be a background activity.
- It shall use the status bar progress bar.

- Email me if you need a specimen document, as the bug tracker hangs while uploading large files.

Alberto, please give us link to your huge file for export to EPUB
Comment 2 Alberto Salvia Novella 2019-12-08 15:31:03 UTC
The file was destroyed due to:
Endless auto-save: Data lost:

Once I regenerate it using a copy I have on Google Drive I will post it here for a month time.

Created attachment 156912 [details]

In order to satisfy the bug tracker upload file size limit, I have cut the document into the first 50 pages.

Please confirm: does it hang for you with this? By hanging, what do you mean? It never completes? It completes, but the resource consumption is outrageous?

I had no problem exporting the file to EPUB and it only took a few seconds.

I also tried with the bigger version I created per bug 129265, but it didn't hang then either.
Comment 8 Alberto Salvia Novella 2020-04-30 18:59:57 UTC
The storage drive died three months later, so that was the cause.

Nevertheless nothing informs that the process is taking place, as the window manager informs that the application isn't responding.

Right, let's adjust the summary.

New sumary sounds to me more like enhancement. I hoe you agree.
