From 52a4c4d82f9c5b808e6c61fd51c1c70e42865565 Mon Sep 17 00:00:00 2001 From: Justin Clarke Casey Date: Fri, 12 Sep 2008 20:12:03 +0000 Subject: * Check in first part of http://opensimulator.org/mantis/view.php?id=2073 * This patch aims to introduce look at direction persistence between logins. It won't be active until the second part of the patch is committed in about two weeks time. At this point, region servers that haven't upgraded past this revision may run into problems * This checkin upgrades the user database. As always, we recommend you have backups in case something goes wrong. * Many thanks to tyre for this patch. --- .../Communications/Local/LocalLoginService.cs | 257 ++++++++++----------- 1 file changed, 128 insertions(+), 129 deletions(-) (limited to 'OpenSim/Region/Communications/Local/LocalLoginService.cs') diff --git a/OpenSim/Region/Communications/Local/LocalLoginService.cs b/OpenSim/Region/Communications/Local/LocalLoginService.cs index 93a1e46..2f7fdb7 100644 --- a/OpenSim/Region/Communications/Local/LocalLoginService.cs +++ b/OpenSim/Region/Communications/Local/LocalLoginService.cs @@ -41,8 +41,7 @@ namespace OpenSim.Region.Communications.Local public class LocalLoginService : LoginService { - private static readonly ILog m_log - = LogManager.GetLogger(MethodBase.GetCurrentMethod().DeclaringType); + private static readonly ILog m_log = LogManager.GetLogger(MethodBase.GetCurrentMethod().DeclaringType); private CommunicationsLocal m_Parent; @@ -120,167 +119,167 @@ namespace OpenSim.Region.Communications.Local } } - private Regex reURI = new Regex(@"^uri:(?[^&]+)&(?\d+)&(?\d+)&(?\d+)$"); - + /// + /// Customises the login response and fills in missing values. + /// + /// The existing response + /// The user profile + /// The requested start location public override bool CustomiseResponse(LoginResponse response, UserProfileData theUser, string startLocationRequest) { - ulong currentRegion = 0; - - uint locX = 0; - uint locY = 0; - uint locZ = 0; - bool specificStartLocation = false; + // HomeLocation + RegionInfo homeInfo = null; + // use the homeRegionID if it is stored already.
