SUMMARY

Encountered in texstudio that opens files on start that were open the last time when opening a file from my laptop via sftp and it went to sleep later


STEPS TO REPRODUCE
1. Open a file in texstudio from another machine from dolphin via sftp 
2. Close texstudio 
3. Put the other device to sleep or cut the network connection of the computer your working on
4. texstudio opens a window but it is transparent

OBSERVED RESULT
The application does not open because it seemingly  blocked by trying to open the file from sftp that is not available currently.

EXPECTED RESULT
Kiofuse should not block other applications when the file is not available
 

Linux/KDE Plasma: 5.4 / master
KDE Plasma Version: master
KDE Frameworks Version: master
Qt Version: 5.15.2

ADDITIONAL INFORMATION
Doing the above but also killing kiofuse allows to open texstudio correctly

I'm confused about which computer is doing what/blocking who. Can we have computer A and B and describe exactly what each one has to do, and when, to replicate this bug?

Comment 2 David Redondo 2021-02-22 07:59:36 UTC

I am on computer A, computer b is remote
- Browse to a file F in Dolphin on computer B, click on it
- file F is opened via kiofuse in textstudio
- close texstudio 
- cut the connection of computer A
- open texstudio that wants to open F but blocks

Why I think that it is a problem with kiofuse: When deleting a file that texstudio wants to reopen on startup, it doesn't block

In terms of it not opening (and blocking) due to no internet connection, unfortunately that's one of the drawbacks of using FUSE and so is a WONTFIX :/

In terms of opening files from a previous session, this is a duplicate
