How are we supposed to open a file without downloading it? Do you view webpages without downloading them? The idea is to be able to "see" the (first) page without downloading the complete file. Since the PDF directory is at the end of the file, the I/O protocol must support seeking, and the actual PDF loading must use scattered seek/read. I am not sure if SMB KIO supports seeking (or if you need to use a FUSE mount for it to work). > Okular downloads [...]

I interpret this as follows: Plasma makes this popup everytime a download is complete, so the user knows when he/she can use the file. But when Okular downloads the file to use it, the user doesn’t care about downloads, but just wants to see the document in Okular.
So the bug is
a) that Okular doesn’t mark the download transaction as “internal” or similar, so Plasma thinks that the user needs to know when it is complete.
b) or that Plasma notifies about such internal downloads although that is useless.
But you want download progress info, what if the file is 300MB and takes a while to get? I really want to see that progress bar The progress bar is fine, the notification that it is finished is useless, because when it is finished, it will show the document anyway. This is different from a regular download, where nothing happens when it is finished (unless there was a "download finished" notification). > the notification that it is finished is useless
Is it? if it's a very long file i may have switched away to firefox to continue looking at cat pictures and i want to be told when the "download" finishes
Initially I thought that Evince doesn't download the file to local file system because it opens the file faster than Okular and plasma shows no notification. I'm wrong. Evince downloads the file as I scroll throught its pages. Apparently it's not possible to open all pages of a document without downloading the file before like we can listen to an audio or watch a video entirely without downloading them.

It is probably more problematic than good to intelligently decide whether to show the notification or not. Then the remaining part of this bug is whether Okular could show the first pages of a document while the last pages are still downloading. If Evince can do that, Poppler apparently can do that, and I don’t see a reason why the Generator interface of Okular couldn’t handle that. (In reply to David Hurka from comment #8) > I don’t see a reason why > the Generator interface of Okular couldn’t handle that. The generators always get passed local files, this means they always need to be complete. If you want to support streaming files, we're going to need to give them a QIODevice, etc. Not totally trivial. Anyhow i'd say we should close this bug and if you want to open one to support Linearized PDF files, there's probably one around somewhere already :D Also evince is probably just using gvfs which does a local mount of remote files so in a sense it's much easier for them, kio is cool but doesn't really help in this case in which we need to seek back and forth in the file Dear Bug Submitter, This bug has been in NEEDSINFO status with no change for at least 15 days.

Created attachment 128637 [details] screenshot STEPS TO REPRODUCE 1. open a samba share containing a pdf file with Dolphin 2. open the pdf file with Okular 3. OBSERVED RESULT Okular downloads the pdf file from samba share to local file system and Plasma notifies about it. See the attached screenshot please. EXPECTED RESULT Okular should open files from samba share without downloading them first SOFTWARE/OS VERSIONS Operating System: KDE neon Unstable Edition KDE Plasma Version: 5.19.80 KDE Frameworks Version: 5.71.0 Qt Version: 5.14.2
