ssh-search-provider doesn't work for new login session until disabled and enabled

[dhwalker]

In Gnome 3.38 / openSUSE Tumbleweed, attempts to find an ssh host after logging into a new session result in only "Searching..." displayed on the screen. Disabling and enabling the extension fixes the problem for the rest of the session; matching ssh hosts are shown on the screen and can be selected.

Thank you for reporting the issue.

Can you please:

1. Enable debug logging for the extension:
   • Launch Gnome Tweaks
   • In the Extensions pane, find SSH search provider reborn
   • Click the gear icon.
   • Toggle the debug button to on.
2. Now reproduce the problem:
   For example remove a host from ~/.ssh/known_hosts, restart gnome shell, login on this host and try to find the host using gnome shell.
3. After having reproduced the problem, attach to this bug the output of:
   • journalctl -S '5 minutes ago' (assuming you've reproduced the problem within the 5 minutes before running journalctl)
   • ls -la ~/.ssh

Thanks for your quick reply.

I think I wasn't clear about the problem I'm having. The "session" I referred to in my original post is the Gnome session that's running ssh-search-provider, not the ssh session, and I'm searching for a host that's already in my known_hosts. Figuring you though I meant a session with a new ssh host in your instructions to reproduce the problem, here's what I've done instead:

1. Toggled ssh-search-provider's debug button on.
2. Logout my Gnome session and log back in (to restart gnome-shell, as I'm using Wayland).
3. Search for "fitlet2". I waited longer than usual and saw that "Searching..." changed to "No results" after a while.
4. Create journalctl.txt and ls-ssh.txt per your step 3.
5. In Gnome Tweaks, disable then enable ssh-search-provider.
6. Search for "fitlet2". This time it's found, I can select it, and I get a gnome-terminal window logged into fitlet2.
7. Create journalctl2.txt and ls-ssh2.txt.

I hope this helps. If you still want me to follow your step 2, let me know.

OK. If I understand your symptoms, you're saying that after logging in a Gnome session, SSH Search Provider isn't able to complete any hosts until it is toggled off and back on.

That is consistent with what I'm seeing in the log files: in journalctl2.txt I can see that you are performing a search:

journalctl2.txt:Jan 02 15:49:29 homelap7 gnome-shell[28940]: Ssh-Search-Provider: SshSearchProvider.getInitialResultSet(fi)
journalctl2.txt:Jan 02 15:49:29 homelap7 gnome-shell[28940]: Ssh-Search-Provider: SshSearchProvider.getInitialResultSet(fi) = 1[fitlet2]

journalctl2.txt:Jan 02 15:49:30 homelap7 gnome-shell[28940]: Ssh-Search-Provider: SshSearchProvider.filterResults(5)
journalctl2.txt:Jan 02 15:49:30 homelap7 gnome-shell[28940]: Ssh-Search-Provider: SshSearchProvider.getSubsearchResultSet(fitlet2)
journalctl2.txt:Jan 02 15:49:30 homelap7 gnome-shell[28940]: Ssh-Search-Provider: SshSearchProvider.getSubsearchResultSet(fitlet2) = 1[fitlet2]
journalctl2.txt:Jan 02 15:49:30 homelap7 gnome-shell[28940]: Ssh-Search-Provider: SshSearchProvider.filterResults(5)
journalctl2.txt:Jan 02 15:49:31 homelap7 gnome-shell[28940]: Ssh-Search-Provider: SshSearchProvider.activateResult(fitlet2)
journalctl2.txt:Jan 02 15:49:31 homelap7 gnome-shell[28940]: Ssh-Search-Provider: SshSearchProvider.activateResult(): cmd=gnome-terminal,--,ssh,fitlet2

However, I don't see any trace of such a search in journalctl.txt.

This seems to indicate that either:

1. Gnome-shell is buggy and doesn't pass the search to the SSH Search Provider

   or

2. Something messes with the search provider list.

Can you try to rule out [1] by:

• disabling all extensions except SSH search provider reborn
• logging out and back in
• does the problem still happen?

When the problem is occurring, can you open looking glass (ALT-f2 lg with default keybindings, then type this expression in the javascript console:

var iter=Main.overview.viewSelector._searchResults._providers.values(); var a = []; while(1) { var d = iter.next(); if (d.done) break; a.push(d.value.id); }; a

This will print something like:

r(0) = a-very-long-line

Click on the value (eg. a-very-long-line in the example above to get it broken down. Your screen should look like this:

Please attach a screenshot, or report if you see ssh-search-provider@extensions.gnome-shell.fifi.org in the list (in my screenshot, it is the last).

[dhwalker]

Yes, your understanding of my symptoms is correct.

Disabling all extensions except for SSH Search Provider Reborn didn't change anything. The information from Looking Glass, though, was interesting. If I display that information immediately after logging in, it doesn't show ssh-search-provider@extensions.gnome-shell.fifi.org on the list:

After using Tweaks to disable and enable it, though, it's on the list:

The interesting thing is that the pre-disable/enable list has org.gnome.Terminal.desktop at position 12, which is where ssh-search-provider shows up after disable/enable.

I think it may be fixed with the latest release (v8).
Would you mind checking?

[dhwalker]

That did it.  Thanks! David

For the record, the fix is to work around a bug in Gnome Shell. But it's working now.

[dhwalker]

Yeah, I suspected that. Thanks again! David
