<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">It's also massively invasive and adds quite some overhead.</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">Why did you not just remove the #ifdef from the slot declaration in Wallet (former patch) and #ifdef the implementation body instead?<br style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: normal;" />
(There are several such internal slots present, you don't have to "fix" the Wallet architecture with this patch ;-)</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">If there's absolutely no other solution and you do not want to add the slot unconditionally, you can still reimplement protected ::timerEvent() and do the timer "the hard way", ie. "myTimer = startTimer(timeout); ... if (te->timerId() == myTimer()) { blahFoo; } else BaseClass::timerEvent(te);"</p></pre>

I also realise I could probably have declared it <code style="text-rendering: inherit;color: #4444cc;padding: 0;white-space: normal;margin: 0;line-height: inherit;">protected QObject</code>.<br style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: normal;" />
I considered your suggestion, but decided against it because it would require patching kwallet.cpp too. Or at least I think it would, I presume one has to provide an implementation for every member function that's declared in the header? Unless one can make the declaration virtual and only provide an implementation in kwallet_mac.cpp (the sort of detail I just cannot seem to memorise :-/ )?</p></pre>

I'm at a point where I think I can present a work-in-progress in an RR because at least one feature has been improved enough to be of interest for everyone, and also because I could use feedback on how to proceed.<br style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: normal;" />
I'm currently focussing on 2 settings that are configured in the kwallet KCM (SystemSettings), and for which I'm working on an implementation not requiring kwalletd and/or DBus.</p>
<ul style="padding: 0;text-rendering: inherit;margin: 0 0 0 1em;line-height: inherit;white-space: normal;">
<li style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: normal;">
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">idle time closing of wallets. This feature was not supported in the commited version presented in https://git.reviewboard.kde.org/r/119838/ The present patch adds an idleTimer and a shared lastAccessTime member. The idleTimer is reset each time a client performs one of a series of actions that I count as wallet accesses, and before resetting I update the idle timeout value from KConfig. When the timer fires, the elapsed time is compared to the shared last access time, and if it is >= the timeout, the wallet is closed. This applies only to "KDE keychains", so keychains used by OS X applications should not be affected.</p>
</li>
<li style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: normal;">
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">"close when last application exits". This requires maintaining a "user list" which keeps track of what application has what wallet open. I've implemented an "internal" version of such a registry, mapping wallet name to application names and the list of wallets they have open (a list of wallet reference, pid per application name). The registry is functional, but I have not yet decided (read: figured out) how to make a distributed representation of it.</p>
</li>
</ul>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">So the work-in-progress concerns the distributed user registry. The idea would be to maintain the registry in shared memory, meaning it'd be reset (= disappear) when the last application exits, contrary to a file which can go stale. This would be simple if QSharedMemory objects could be resized, but apparently they cannot, so I'll have to look at other solutions possibly involving OS X frameworks (NSData and it's non-objectiveC version CFDataRef or CFMutableDataRef might be candidates). Suggestions welcome.</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">Other work in progress concerns a less wheel-reinventing approach that builds on kwalletd and DBus. I don't see why the code used in <code style="text-rendering: inherit;color: #4444cc;padding: 0;white-space: normal;margin: 0;line-height: inherit;">kwallet.cpp</code> wouldn't work, but I must still misunderstand its finer details. The present patch contains outcommented code that does indeed cause kwalletd to be launched and slots and signals to become visible e.g. in <code style="text-rendering: inherit;color: #4444cc;padding: 0;white-space: normal;margin: 0;line-height: inherit;">qdbusviewer</code>. But they don't work, which in turn makes the whole kwallet layer dysfunctional. Here too feedback is welcome on how what I'm missing and/or how to get this to work.<br style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: normal;" />
Once kwalletd works, wallet idle timeout closing and closing when the last client exits should work out-of-the-box, or at least I suppose.</p></pre>
