You could rename slotDefaultState() to setDefaultState() and just call it directly where you currently emit defaultState. Signals are meant for the "outside" (users of the class), but here they are internal. Same for the other signals below. I think direct method calls will improve readability, the control flow will be easier to determine. src/widgets/kpropertiesdialog.cpp (line 2661) <https://git.reviewboard.kde.org/r/128283/#comment65529> This would be done in setDefaultState(), for instance. If one day an if() has to be added or something, it will be easier ;) src/widgets/kpropertiesdialog.cpp (line 2772) <https://git.reviewboard.kde.org/r/128283/#comment65531> This should be an if(), not a tri-state operator returning void. src/widgets/kpropertiesdialog.cpp (line 2777) <https://git.reviewboard.kde.org/r/128283/#comment65530> the 3rd argument should be "this" src/widgets/kpropertiesdialog.cpp (line 2799) <https://git.reviewboard.kde.org/r/128283/#comment65532> if () src/widgets/kpropertiesdialog.cpp (line 2844) <https://git.reviewboard.kde.org/r/128283/#comment65533> what if the file changes while this dialog is up? (e.g. during a download). Maybe a change of size or mtime should invalidate the cache? src/widgets/kpropertiesdialog.cpp (line 2851) <https://git.reviewboard.kde.org/r/128283/#comment65534> add this as 3rg arg (to avoid crashes if the dialog is closed before this finishes) src/widgets/kpropertiesdialog.cpp (line 2863) <https://git.reviewboard.kde.org/r/128283/#comment65535> This method is called from the secondary thread, so the private class needs a mutex to protect d->m_md5, d->m_sha1 and d->m_sha256 Alternatively, check the cache outside of the method called by QtConcurrent. After all it's wasteful to create a QtConcurrent task just to realize we have no computation to do. src/widgets/kpropertiesdialog.cpp (line 2896) <https://git.reviewboard.kde.org/r/128283/#comment65537> I would make this a file-static method, to make sure you're not accessing any member variables from the class from a secondary thread (undefined behaviour, without a mutex). If you remove the cache check and pass the filename as argument, then you don't need "this" anymore, it can be static and race-free. src/widgets/kpropertiesdialog.cpp (line 2899) <https://git.reviewboard.kde.org/r/128283/#comment65536> double lookup, use a local variable - David Faure On June 30, 2016, 8:57 a.m., Elvis Angelaccio wrote: > > ----------------------------------------------------------- > This is an automatically generated e-mail.
