#4355 closed defect (fixed)

UPnP share path missing in GetServDesc

Reported by: otto at kolsi dot fi Owned by: dblain

Severity: medium Keywords:
Cc: Ticket locked: no


Fix in [15220] tries to fix the path for UPnP files but GetServDesc? method still fails to locate CMGR_scpd.xml file.

Now the SharePath? is okay:

2007-12-23 15:23:30.974 HttpServer( 6544 ) - SharePath = /usr/local/share/mythtv/

But when GetServDesc? is received, the file is still opened without full path and it fails. I've modified this one log print to show what file/path is used:

2007-12-23 15:23:41.809 UPnpCMGR::ProcessRequest - Method (GetServDesc), file: CMGR_scpd.xml
2007-12-23 15:23:47.704 UPnpCMGR::ProcessRequest - Method (GetServDesc), file: CMGR_scpd.xml
2007-12-23 15:23:49.114 UPnpCMGR::ProcessRequest - Method (GetServDesc), file: CMGR_scpd.xml

Problem can be solved by adding "UPnP/DescXmlPath" setting wo DB but I think this is supposed to work without that setting.

It looks like something hinky with GetValue?, but I cannot fathom what. This extra debug:

(In [15224]) Prevent GetSetting?() from storing a QString::null in the settings cache. UPnP currently does this with UPnP/DescXmlPath. See #4355. The correct fix is for the caller to not send null as a defaultval, but checking for this will add a little robustness.

(In [15231]) UPnpCMGR::ProcessRequest?(CMGRM_GetServiceDescription) uses the filename which is set at object creation time, so this passes the share path in to the xtor. Should fix the current UPnP issue. See #4355. See #4317. See #2467.

Note 1) the frontend MediaRenderer? shouldn't need to share anything(?),

so its xtor gets an empty string.

Note 2) I suspect [15220] can be reverted,

but I will wait for David Blain to verify that
