Comment 1 Mikko C. 2009-09-10 14:04:26 UTC 
not sure if this is already fixed... bart?
Comment 2 Myriam Schweingruber 2009-09-10 18:10:20 UTC 
Media Devices would be Alejandro, no?

#5  SqlUserPlaylistProvider::checkTables (this=0x488db60) at
../../src/playlistmanager/sql/SqlUserPlaylistProvider.cpp:354

^ That seems quite suggestive of a crash in SqlUserPlaylistProvider, which isn't exactly media devices.

From what I can tell, it's a case of the PlaylistManager doing Sql stuff before Sql stuff is ready (i.e., an sql query), because MediaDevice stuff is trying to talk to the PlaylistManager, which then tries to set itself up and crashes because it's too early for that.  Another unfortunate case of "attack of the singletons!" (tm).
Comment 4 Maximilian Kossick 2009-09-13 20:23:05 UTC 
This has nothing to do with singletons. It's just that there is no guarantee that SqlCollection has been loaded at that point, i.e. before mediadevices are loaded (and that SqlUserPlaylistProvider does not check for a null pointer obviously). That guarantee has to be made explicitly.
Comment 5 Alejandro Wainzinger 2009-09-13 20:33:48 UTC 
It's the PlaylistManager that triggers creation of the SqlUserPlaylistProvider however.  What I mean by a singleton issue, is that no matter when a singleton gets instantiated, by whomever, it should always make sure there's no crash.

In this case, something I talked over with Bart a while back makes sense, which is associating the default SqlUserPlaylistProvider with the default SqlCollection.  There's already a UserPlaylistProvider associated with each of the media device collection types.  This way, we can be sure that the collection exists when the provider is created.
Comment 6 Bart Cerneels 2009-09-14 12:43:07 UTC 
To clarify #5: The idea is the SqlUserPlaylistProvider is part of the .so/plugin of SqlCollection. This is more to group functional dependencies and have the possibility in the future to run an amarok without any SQL dependency. 

There will always be a need for default providers though. The current method (calling the constructor within PlaylistManager c'tor) might not continue to work. And at the moment the default is hardcoded. I've always intended this to be configurable though rc-file or distro default.
Comment 7 Rene Ploetz 2009-10-04 12:35:30 UTC 
I believe my amarok suffers from the same bug using an external mysql server.
If I first start amarok with the git-version built around 12 hours ago, at the first start amarok simply hangs displaying the logo and saying on console after a while:

<unknown program name>(16950)/: Communication problem with  "amarok" , it probably crashed. 
Error message was:  "org.freedesktop.DBus.Error.NoReply" : " "Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken." "

If I do "kbuildsycoca4 --noincremental", I can crash amarok rather reliable with the following backtrace (note that this bug does not always show up, sometimes you get to the interface but cannot fetch any data from the mysql server):

Comment 8 Mark Kretschmann 2009-10-04 13:12:15 UTC 
@Rene: Your crash is apparently unrelated to iPods. It's crashing in MySQL:

Comment 9 Mikko C. 2009-10-04 13:37:09 UTC 
@Rene: you might want to look at bug #209380 it seems very similar
Comment 10 Myriam Schweingruber 2009-11-16 22:16:13 UTC 
Bart, Alejandro, any news on this?
Comment 11 Bart Cerneels 2009-11-17 09:21:03 UTC 
Assuming this was caused by the sqlStorage not being available, the recent obsessive pointer checking would have fixed this.
Comment 12 Myriam Schweingruber 2009-11-17 10:29:56 UTC 
OK, closing as fixed for now. Feel free to reopen this report if you can reproduce this with current Amarok 2.2.1 or higher.
