Save As not writing to specified location

[mMerlin]

environment 4.18.16-100.fc27.x86_64 ¦ Fedora 27 Fritzing: 0.9.3 b5c8959

Fritzing installed from flatpak does not save documents to the proper location. No error messages, and the log messages look reasonable, but no file is created. The only place I have been able to find saved files is subfolders of path /run/user/1000/doc/by-app/org.fritzing.Fritzing/

It appears that the Fritzing app does not have permission to get write access to the file system out side of the flatpak sandbox.  Read works, to access previously saved fzz files.

[gasinvein]

Does it work correctly with --filesystem=home, e.g. if you run Fritzing via flatpak run --filesystem=home org.fritzing.Fritzing?

[mMerlin]

That did not help. Further testing:

I also have org.fritzing.Frizting installed on another machine. The latest Fedora 29. On there it works fine, even without the --filesystem=home. On Fedora 27, it does not work either with or without the filesystem override. Looking at the console messages, the obvious difference is that Fedora 27 gets the Gtk-Message: Failed to load module messages on startup. Fedora 29 does not.

Could that be a problem with the runtime? The details shown by flatpak info looks identical. Other than the home folder.

[gasinvein]

This looks much like flatpak/flatpak#1307, and I can't reproduce it myself. Which flatpak versions are on your machines? Also, are the files you trying to save under your /home (if not, try --filesystem=host)?

[mMerlin]

The path for the file attempting to save is in my home directory /home/«username»/

Flatpak version, on both FC27 and FC29

$ flatpak --version
Flatpak 1.0.4

Tried using --filesystem=host anyway. Same result. The file (with FC27) gets saved to a subfolder of /run/user/1000/doc/by-app/org.fritzing.Fritzing/. Correct file name, but in an 8 hex character folder name.

No idea if it is related, but the file dialog on fc27 is opening under the app window. That caused some initial confusion when the app was full screen. Now I know to go look for it. On fc29, the dialog opens on top.

[gasinvein]

It's most likely related to xdg-desktop-portal, but sadly I don't have enough knowledge of flatpak itself. Maybe @TingPing could help?

[TingPing]

That is how the portal works, the application writes to /run/user/1000/doc/by-app/org.fritzing.Fritzing/... but the actual file should totally exist on the host where you set it to.

[mMerlin]

sudo find / -name "«unique save name.fzz» -type f -print did not find any reference. Just the one in /run/user/1000/doc/by-app/org.frizting.Fritzing/«hexfoldername»/

Spinning up a fc27 VM for next test. In case my main machine has gone strange over time.

[TingPing]

Does it show up in flatpak document-list org.frizting.Fritzing

[mMerlin]

Yes. All of the missing files show up in that list, with the correct (target) folder, and the prefix matches the folder name seen in /run/user/1000/doc/by-app/org.frizting.Fritzing/. That list just does not have the .fzz suffix, except for the previously existing files that where opened (not those saved).

[TingPing]

That list just does not have the .fzz suffix, except for the previously existing files that where opened (not those saved).

Hmm. That sounds relevant, maybe the application is appending that itself (and thus not writing to the correct place). Dunno but I think the document export looks correct and it would make sense for the issue to be on the application side.

[mMerlin]

Of course it is working on another machine with Fedora 29 instead of Fedora 27. In that case (fc29), document list is empty, and so is the /run/user/1000/doc/by-app/org.fritzing.Fritzing folder. The files (only) exist where they were explicitly saved to, and have the .fzz suffix. As noted in a previous comment, flatpak info looks like identical app versions (commit and parent) for the 2 machines.

[mMerlin]

YES it is related. Did a test where I saved again, this time explicitly specifying the default .fzz suffix. The file got saved were I told it to. It still also shows up in both the document-list and by-app folders. With FC29, it looks like those are deleted when the file gets successfully saved.

[mMerlin]

Replicated on a fresh fc27 VM. Installed as system instead of user. Specifying the .fzz suffix saved the file to the target folder. Leaving it off did not. In both cases, document-list shows the specified file and path, while …/by-app/… contains the file with the .fzz suffix.

The only difference noticed with the VM, is that the file dialog is opening on top of the app.

[gasinvein]

Just did a local build with KDE runtime 5.11. While the current Flathub's build saves files as expected (if file extension is specified), my local build does not. The only noticeable difference is in permissions, which I assume are inherited from the runtime:

org.fritzing.Fritzing/x86_64/stable flathub 7627c7937375
  permissions: ipc, network, pulseaudio, wayland, x11, dri
  file access: xdg-documents

org.fritzing.Fritzing/x86_64/stable homeserver 8b0e9ab16598
  permissions: ipc, network, pulseaudio, wayland, x11, dri
  file access: xdg-config/kdeglobals:ro, xdg-documents, xdg-run/dconf, ~/.config/dconf:ro
  dbus access: com.canonical.AppMenu.Registrar, com.canonical.AppMenu.Registrar.*

@TingPing can some of these affect portals behavior?

[TingPing]

@gasinvein I'm not super familiar with Qt honestly, but I would expect them not to.

[gasinvein]

I've also flatpack'ed another (electronics-related) Qt app - SimulIDE, and it has similar behavior - "save as" dialog works fine only if filename extension is explicitly set. Didn't notice it before. So, is this a runtime/portal bug, or I'm doing something totally wrong?

[TingPing]

Probably Qt related, so I'd try discussing it with them.

[gasinvein]

This should be fixed after KDE/flatpak-kde-runtime@819fabd.

@mMerlin can you check if the bug persist?

[mMerlin]

That does not seem to have fixed the problem. In fact it seems to be broken worse. Now it will not save a file even when specifying the file extension. Using a fresh FC27 VM snapshot, updated flatpak version, fresh install of Fritzing.

[gasinvein]

This issue is likely caused by the host side of the portal. What version of xdg-desktop-portal-gtk do you have?

[mMerlin]

Currently 0.99m with 0.7-3 also available in the standard repos

Well, at least with 1.2.0 (which is in f29 repos) Fritzing works fine. Since Fedora 27 is EOL, if you really have to use it, I suggest you updating xdg-desktop-portal and xdg-desktop-portal-gtk to latest upstream versions.

[mMerlin]

My linux-fu is not good enough to sneak that into fc27. Attempting pulled in a lot of dependencies, and still failed to upgrade. At least the flatpak works as long as I save into (subfolders of) $HOME/Documents/Fritzing.

[gasinvein]

Mixing packages from different releases is a really bad idea. If you can't upgrade to latest Fedora, you should rebuild SRPMs from newer release for your system.

[mMerlin]

Sure, should rebuild. Outside my skill set though. Full upgrade on the list. Have VMs for now when needed, and can mostly work with the existing flatpak now that I know where the limitations are.

[gasinvein]

Here, I've build those packages for you. It should work, but may introduce problems, use at your own risk if you don't mind installing random stuff from the internets. xdg-portal-packages-fedora-27.tar.gz N.B. mutter is built without pipewire and thus without remote desktop support.

[mMerlin]

I successfully installed the updated xdg-portal packages on a FC27 VM snapshot, but the app still can not save a file to the home directory, without specifying the .fzz extension. Messages say it is saving to the correct name (with the extension), but the file does not actually exist. Something else in the mix is needed.

Fuller logs are availble, or reproducable, if you are interested. I tried it, just to see if it would work. Not planning to actually use that environment, or the updated packages in my main environment. Other options are good enough at this time.

[gasinvein]

Tested on openSUSE TW with KDE, and there file extensions are automatically appended. So this issue is somewhere between Qt in flatpak and the desktop portal on the host. Probably it should be reported to xdg-desktop-portal-gtk.
