From: Dale Whittaker Date: Fri, 23 Jan 2009 21:38:39 +0000 (+0100) Subject: Store the 'day' of history items to reduce even more calls to localtime X-Git-Url: https://spindle.queued.net/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=fb2a962ad4d4a0976307e532cfe16316fde8dbcc;p=midori Store the 'day' of history items to reduce even more calls to localtime By storing the timestamp of the day in the database we can significantly reduce the calls to localtime, which should result in a noticible speedup. We are changing the database format. For the convenience of the user the code automatically converts from the old format. --- diff --git a/midori/main.c b/midori/main.c index 31efc1ca..6d0fe3b1 100644 --- a/midori/main.c +++ b/midori/main.c @@ -716,10 +716,11 @@ midori_history_add_item_cb (KatzeArray* array, } } sqlcmd = sqlite3_mprintf ("INSERT INTO history VALUES" - "('%q', '%q', %" G_GUINT64_FORMAT ", -1)", + "('%q', '%q', %" G_GUINT64_FORMAT ", %" G_GUINT64_FORMAT ")", katze_item_get_uri (item), katze_item_get_name (item), - katze_item_get_added (item));
