Catalog Sources disappear

[iandol]

This is fairly recent, but I've noticed with 3928 that when adding a filetype to a custom folder scanner (that may have been coincidental) that every catalog source disappears in the catalog prefs UI, even if QS can still use the catalog. Lion 10.7.4, console output is the following:

17/05/2012 00:12:35.173 Quicksilver: NSOutlineView Warning: reloadData called while in the middle of doing a reloadData (break on NSLog to debug)

Well, I can’t get this to happen, but the error “reloadData called while in the middle of doing a reloadData” makes me wonder if it’s related to a recent change. @pjrobertson fixed things so the contents would get updated in real-time as you make changes to the entry.

Are you able to do this consistently? Is there a particular type you add that triggers it, or a particular path?

[pjrobertson]

FWIW, I've occasionally seen my catalog get wiped, requiring me to restore
catalog.plist using Time Machine. I haven't looked into it though, and it's
not new. For me at lest, I think it's related to debugging Quicksilver and
force quitting the app before it has time to register the catalog. Or
starting QS with the catalog disabled (hold ⌥ on startup) then opening the
Catalog prefs

In my case, I can still use the catalog contents so this is just a UI issue but everything is missing (Applications, Modules etc.). I've tried reproducing it on another machine and I get reliable crashes doing the following:

Add custom Folder to catalog, add a Type = *.avi — select outside then back into the Type box and I crash. I've sent 2 crash reports with this issue in the comment. I can't reproduce the catalog going blank yet, but in one case I noticed the Prefs window closed but QS was still running (not a full crash) so something is going wront with the prefs catalog UI. The crash is reproducible at the moment so can collect more info if needed.

Add custom Folder to catalog, add a Type = *.avi — select outside then back into the Type box and I crash.

I can reproduce this by entering *.avi, but you should just enter avi. Not only will that actually do what you intended, but it seems to prevent the crash.

We still need to investigate and fix the crash. I wonder if it’s as simple as removing *. from the input if that’s what someone types.

As for the original issue, it sounds like a rare race condition, so it could be hard to track down.

I just saw my catalog (in the preferences) go blank as well for a completely different reason. I went into Modules, selected iTunes and hit refresh. Everything disappeared.

From the Console:

Can reproduce the iTunes > Refresh too...

[pjrobertson]

OK, an easy way for me to reproduce this:

• Open the Catalog preferences
• Move ~/Library/Caches/Quicksilver to the trash
• Open the Quicksilver interface and press ⌘R to rescan the catalog.

The bug seems to be that the QSOutlineView (that shows the catalog entry) isn't being told that the catalog entry is being updated. We probably either need to look out for if the data is 'nil', or use some kind of KVO.
