Ship it!


Here's a first review, I have not been very thorough as the branch is still not completed. I am marking it as "Ship it" despite the comments below given that this review was meant for a general heads-up before finishing the work - in this light, the patch looks very good already. However, there are some nitpicks:


account.h
<http://git.reviewboard.kde.org/r/100439/#comment835>

    Constify if possible



account.cpp
<http://git.reviewboard.kde.org/r/100439/#comment836>

    Short reminder here as well: SIGNAL and SLOT signatures should be always normalized: so "QString" instead of "const QString&"



nepomuk-storage.h
<http://git.reviewboard.kde.org/r/100439/#comment838>

    These two classes seem like good candidates for being implemented with Implicit data sharing to me - what do you reckon?



nepomuk-storage.cpp
<http://git.reviewboard.kde.org/r/100439/#comment839>

    I'd remove those asserts (as in this one and all similar occurrences) in the final version - after all, you are checking for  existance in the next line.



nepomuk-storage.cpp
<http://git.reviewboard.kde.org/r/100439/#comment840>

    This line crafts an unused variable. Look out - most of these methods are affected by this problem.



nepomuk-storage.cpp
<http://git.reviewboard.kde.org/r/100439/#comment841>

    I am a bit concerned about this as well. First of all, I wonder if qHash() is needed at all in this case.
    Moreover, if it is true that some accounts have no ID, if we had 2 accounts without ID having the same contact ID we would end up with a duplicated key.
    I have no idea on how to get this one right though.



service.cpp
<http://git.reviewboard.kde.org/r/100439/#comment842>

    Triggering shutdown in the destructor is a good idea only if the shutdown is a sync process. Otherwise, given that we're the first in the chain and all of the created objects are our children, we might end up having some weird crashes on exit caused by having a function called on a dead object.
    
    Especially, I see that most of the classes are emitting signal on shutdown, so I think it's quite realistic to expect some crashes on exit.

I'm putting this up here for preliminary review comments however, because it's blocking a lot of development at the moment, so I'd like to get it moving again.
