@ikloecker I suggest giving up on this, I know that it is frustrating but it does not make much sense, it is probably related to some compiler settings / Qt cross compile issue and might be a bug in qt. Just do an old style connect and leave a comment that we will revisit this with Qt6. When VSD 3.2 is our last major release based on Qt5 we should not spend too much time investigating this which might be completely different (or not) with Qt6.

@ikloecker I thought about this some more. Why do we do the READKEY when we could look up the keygrips and see that we already have keys for this. That sounds to me like a simpler fix then changing how gpg-agent behaves here. Although I still think that gpg-agent is in the wrong to just overwrite and potentially delete softkeys here.

Ok since this does not happen with other cards this is definetly a gnupg issue I just checked with a telesec card and the behavior there is different.

And it's the signals that are not found. I don't see any indication that this has anything to do with the slots/lambdas.

Well, the failed new style connects are logged for me with "QObject::connect: signal not found in QGpgME::QGpgMEQuickJob". I haven't dug into how the check works for those connects. It turns out that none of the three connects to the signals of QuickJob work (two of those connects are done in ProgressDialog). Even the connect to the argument-less done() signal. So this has nothing to do with default arguments. This is very disturbing because this means that any other connect might also be broken.

@werner I think this question is for you to answer. IMO these files should not be overwritten. I mean they could contain actual secret keys instead of just the shadow keys and then those would be overwritten, right?

Ah no I see the difference here. Instead of connecting to a lambda with no args 96da231f97eff9485f62ab925d81252f5f97fc31 connected to the functions which were used in the old signal / slot syntax. I think the fix might be to explicitly list the args of the quickjob result or to use afunction to handle the keygenresult.

works, VS-Desktop-3.1.90.287-Beta

It does not log failed connections but new style connections are never logged when they fail. Since they can't fail ;-)

Let me put this on the 3.2 workboard since we already have the "reports error when canceled" on that workboard and T6566 too depens on this, in fact I am currently working on this even though it was not on the workbaord.

Seems T6813 blocks me from testing this. The generate window does not close and even if I abort the window, the generated key is not loaded. It is not selectable even if I remove the filter.

Okay. How do we fix this? Make gpg-agent not rewrite the files again and again if nothing changed? Stop watching the private key files for changes and then miss updates in Kleopatra causing weird update problems like T5546: Kleopatra: After importing the first pubkey for a card from LDAP the keylistview is not refreshed for which I have introduced watching of the private key files?

Yes these files are rewritten on every iteration.

The following logs indicate that the file system watcher detects a change of those files and that triggers an update of the keylist and the smart card view. Please check whether those files are indeed rewritten on every iteration.

Confirmed with two other cards. in the gpg-agent log I also see MARKTRUSTED not supported lines while the card is inserted - this is cause by the loop in Kleo.

works, the .part file is deleted on Windows, too, VS-Desktop-3.1.90.287-Beta

I know that there is an issue here that the about data in the option dialog of gpgol that is fixed with afb6ce9ce00538242ac69434f586749217f9f619 but did not make it in the current beta. And since this is also related to the tender version i leave this a bit open for now. I think we also might need to reload the welcomewidget in case the signature verification takes longer then constructing the welcomewidget.

Yes, we can probably wait for Qt 6. It may anyway need to be fixed directly in Qt.

Does Qt log failed connections?

Just my five cents:

So I tested this with an S/MIME certificate for which the CRL was not available and as described by the original reporter Outlook just froze. And you had to kill it. With the current beta you would get the dialog to encrypt the message anyway but this does not make sense for draft encryption where you can only select your own keys.

@ikloecker I would like your opinion if this should not wait for Qt6 if it is an issue with Qt. I guess "prio low" would anyway mean. "Let us leave this for a while" :)

The count in procmon for kleopatra.exe when starting Kleopatra returned 26434 in VSD 3.1.26 and only 14026 for Beta-277 in my test.
