Git commit b1a251ebb96b86c8cba83343719fa8e67ab4ee9b by Elvis Angelaccio. Committed on 25/02/2018 at 22:41. Pushed by elvisangelaccio into branch 'master'. Rework kill logic The libzip plugin sometimes cannot react to `QThread::requestInterruption()` because there is a blocking `zip_close()` which writes to disk (e.g. with AddJobs). This means we have to manually abort the thread (by passing a timeout to `QThread::wait()` in `Job::doKill()`. We cannot do this uconditionally because we would end up with crashes in libarchive. Since the libarchive plugin is not affected by this problem, we rework the logic in `Job::doKill()` by assuming that the interface will tell us whether it needs to be brutally killed. This way we can distinguish between the libarchive and the libzip plugins (the ones that use a worker thread). The mutex in this patch is needed because in theory `m_operationMode` could be read and written by different threads at the same time, even though that's unlikely.
