Exporting History from Konqueror

In my Konqueror settings I have had it retain my history sense August 2006. This has resulted in a history file that contains over eighteen thousand entries. As you can guess Konqueror has some trouble with a history of this size. A dataset of this size is a good way to test any history managers memory usage and performance. I was hoping to be able to export the data with dcop, but unfortunately the only function available is allUrls which doesn't make that much sense because the dates are just as important as the urls. To see your history urls with dcop use

dcop konqueror-11489 KonqHistoryManager allURLs

replacing 11489 with your Konqueror number of course. Reaching a dead end with dcop I whipped up a tool that uses libkonq to extract the history.

#include <kapplication.h>
#include <kcmdlineargs.h>
#include <konq_historymgr.h>

int main(int argc, char **argv)
{
    KCmdLineArgs::init(argc, argv, "konqueror", "konqueror", "I do stuff", "0.1");
    KApplication application(argc, argv);
    KonqHistoryManager manager(0, "manager");
    KonqHistoryList list = manager.entries();
    for (uint i = 0; i < list.count(); ++i) {
        printf("%s\n%s\n%s\n",
                list.at(i)->url.url().latin1(),
                list.at(i)->title.latin1(),
                list.at(i)->lastVisited.toString().latin1());
    }
    return 0;
}

Already this data has proved useful and helped me reduce my memory footprint by half and catch my performance bottlenecks so it can handle 20 entries or 20,000 just as fast. If you are interested in playing with the dataset send me an e-mail.
