Noise blank on startup, freezes when clearing searches

[ClassicalBadger]

When starting Noise, the area normally occupied by the album/list/colum views is entirely blank, and the program appears to be frozen. The program will not react to any mouse actions and will be completely unresponsive. The contents of the window will not adjust if it is resized.

This also occurs when trying to clear a search, though for a shorter period of time- during which I am also unable to pause music through the sound menu in wingpanel or through keyboard shortcuts.

Attached is the output I get when opening Noise via the terminal with gdb and run-d, and when entering and then clearing a couple searches. I am currently running the 64-bit version of Luna Beta 2 with kernel 3.9, though this problem is encountered repeatedly when running either 3.9 or the default kernel.

This is technically a dupe of bug 1082944, but I don't know if I should mark it since it is marked as "Fix Released" (and won't show up as a dupe when somebody tries to report this bug again)

[Cameron Norman (cameronnemo)]

If it is a duplicate of that bug, it would be caused by a large music library. Mind telling me about how many songs you have?

[ClassicalBadger (idiotjoy)]

I do have a large collection: 5575 songs spread across 387 albums (though 108 of those are just individual songs), coming in at 43.0GB (a significant portion of the songs are in FLAC).

To put things in perspective, it takes Noise roughly as long to start up and become in any way responsive as it does for Rhythmbox to do its initial import of all of my music, which it does not have to repeat upon future starts. Personally I think marking this as a duplicate bug when the existing fix still leaves Noise unusable would not be pragmatic. Noise is a fairly specialized, single-purpose program and I don't think it's unreasonable to expect it to handle large libraries better than it currently does.

It should be a lot better now, can you test it after updating Noise ?

[Danielle Foré (danrabbit)]

I can confirm the issue still persists. All these problems started after revision 1394

[Corentin Noël (tintou)]

I've tested with 5200 songs with the today's commit and it's not that bad, is it also better for you ?

[Łukasz Halman (lukasz-halman)]

For me with ~3500 songs it's definately faster now. Down to 10 seconds, where it was almost a minute before, but I wouldn't call it acceptable still. Music should just show up. If there are any changes to filesystem app should update its state in background.

[ClassicalBadger (idiotjoy)]

With the recent update, startup went from about 1-2 minutes of unresponsiveness to 7-10 seconds. Clearing searches went from 40-60 seconds of unresponsiveness to about 4 or 5. Overall, a very significant improvement.

[Danielle Foré (danrabbit)]

I'm still clocking a 8.6 second startup time with only 2,404 songs. I don't remember this being an issue at all before revision 1394.

I've noticed a significant improvement with the latest builds. I have a largish library of around 11,500 tracks and startup time is down from around 55 seconds to about 14 seconds. This is a big improvement but is still quite slow - for comparison on the same machine with the same library beatbox and gmusicbrowser both start up in about 4 or 5 seconds.

[Corentin Noël (tintou)]

Latest Noise is now much faster at startup, thanks all for your tests !

[Corentin Noël (tintou)]

But Noise performance improvement will continue in the future…
