(Updated Jan. 3, 2015, 8:42 p.m.) Review request for KDE Software on Mac OS X and kdelibs. Repository: kdelibs Description ------- I'm still working on (the KDE4-based version of) my OS X keychain backend for kwallet. 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. 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. - 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. - "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. 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. 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 `kwallet.cpp` 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 `qdbusviewer`. 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. 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. Diffs ----- kdeui/util/kwallet_mac.h PRE-CREATION kdeui/util/kwallet_mac.cpp 8344ebb kdeui/util/qosxkeychain.h d0934e6 kdeui/util/qosxkeychain.cpp 7cb9a22 Diff: https://git.reviewboard.kde.org/r/120202/diff/ Testing (updated) ------- OS X 10.6.8 and OS X 10.9.5, kdelibs 4.14.n git/master, KDE/MacPorts 4.12.5 & 4.13.3. Once finalised, all changes should port easily to KF5's kwallet_mac.cpp . Thanks, René J.V. Bertin
