RCB Freezes On Import if folder has no games in it? #175

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago 
What steps will reproduce the problem?
1. Using a blank MyGames.db to mimic a "first run"
2. Choosing to import games from a ROM folder that has none in them

The best thing to do is review the installation page I am doing on my project:  
https://github.com/ProfessorKaos64/RetroRig/wiki/Installation

I load a "skeleton" of MyGames.db with config.txt It works great if there is a 
ROM file in the folder, so I know this method works, and applaud you for this 
software. However, when there are no games in a folder, let's say you choose 
"All" for 5 folders when you only have ROMs in one, it just freezes XBMC it 
seems, or stalls. I think this is VERY fixable, with some kind of detection in 
the XML code or somewhere, to just kick out of the importer, or give an 
immediate error. If you point me to the relative spot where this is, maybe I 
can put on my thinking cap and look into it. The full project page is:  
https://github.com/ProfessorKaos64/RetroRig

What is the expected output? What do you see instead?
Just "importing" freezes XBMC

What version of the product are you using? On what operating system?
Latest version pulled down from XBMC Gotham 13.1 Git:f2acae7 (july 6 2014)

Please provide any additional information below.

You can contact me here or via libregeek.org

Thank you!!!!

I've attached a zip file of my prebuilt folder set for XBMC. Ignore the 
XBMC-session folder,its for another code function.

Maybe you could put a timeout in, so if nothing happens for 10 seconds or 
internal error prevent some steps from occuring.

#check if background game import is running     
if self.checkUpdateInProgress():            
self.quit = True            
return

I would figure one of these functions has the answer (from gui.py)

def importGames(self, romCollections, isRescrape):      
self.saveViewState(False)       
self.clearList()        
self.clearCache()       
self.checkImport(3, romCollections, isRescrape)     
self.cacheItems()               
self.updateControls(True)       
self.loadViewState()

I wonder if I clean the database on startup in the xml start settings, if that 
will make a difference.

I'll make sure to scan the xbmc.log for information noted in 
http://code.google.com/p/romcollectionbrowser/wiki/ImportGames#Import

I don't really understand your scenario. I tested to do an import from an empty 
folder and RCB behaves as expected: it does not import anything but it also 
does not freeze.

Is it because I am using a "blank" MyGames.db with a config.xml file that is 
pre set up? I'll try to test this again tonight.

What can I show you to show you what happens when it freezes? XBMC's log?

I see what it's doing, it's trying to check every* game in the offline scraper 
for some reason:

Is there a reason for this?

I tried removing the scrape results before trying again, but didn't make a 
difference. At least I know now that the reason why its "waiting" is it's 
scanning every MAME game. There must be a setting or something I can clear 
before hand in my script.

So it looks like it does not really freeze but it just stupidly scans 
description files?

Maybe that is a good hint for me to investigate. I guess there is nothing you 
can do about it by configuration. I have to check the code why it starts 
scanning the description file even if there are no games to scrape.

Yep, at least I see now what happened, something triggers the offline scraper 
to just go through the whole mame.txt list and sit at the main screen. Even as 
a small fix, knowing where it was in that would be something too, but for me it 
just shows "adding roms". Sorry for the confusion, but I think we're on the 
same page now.  Thank you maleop. I'll try to test this a few more times today 
to see the conditions, but most times it was either nothing left to import/add, 
or nothing in any folder, possibly.

It is fixed in svn now: 
https://code.google.com/p/romcollectionbrowser/source/detail?r=1820

It will take some more time until I release a new version. But you could 
already get it via svn or do the change yourself if you don't want to wait.

Meh, it is too early. You also have to apply this bugfix:

Both of those links are for dbupdate.py Does the second link source super-cede 
the first? Thank you for looking at this.

Tested this fix out, seems to work great, Thank you very much. It snaps right 
back to the game selection when no ROMs are present. kudos

When I do a second time import, I still get game scans in the offline scraper:
