Is the above backtrace useful? Then this bug should be reopened

It looks useful to me, yep. Reopening then.

I got the same problem. Ever since Amarok2 came out I tried to use it but it never managed to import my collection, so I stuck with 1.4.

However, here's what happens.

1. Start Amarok 2
2. Tell it to scan collection
 -> It will start and stop at ~25% with no comment, about 25% of the collection are imported at this point.
3. Tell to to rescan
 -> Crash with this stacktrace

Ah, it's OpenSuSE 11.1 64 bit by the way. Binary packages

HTH,

Stephan

So, as I've said before, I'm unable to reproduce these bugs, but it's very likely that I haven't taken all database setups into account.

Amarok 2.0.2 will be released very shortly, and I'll add some extra debug to help solve the problems.

I'll report back with further instructions soon.

Well, I've got quite an extensive collection (~50G) and it contains all sorts of ID3 and data types (mp3, lotsa ogg, flac, ect). I tried to run amarok2 from console to see if it does any stderr to indicate the problem but there was none. If you could cout some status about where in the collection recursion the scanner currently works one may be able to pinpoint a specific file or dir that causes the crash.

Cheers,

Stephan

I tried to strace into the processes to find the cause.

It seems to happen after the collection scanner writes some large chunks into what I can only assume is some sort of index file.

Couldn't see what file caused it though but I got some traces of forked processes that tried to scan files that are not actually there anymore but have been a couple of months ago. Apparently this is caused by old cached data.

Does that help?

Stephan

I can now reproduce this every time I try, but instead of a crash I get a total freeze with no useful backtrace :(

2.1-SVN on Kubuntu Jaunty RC, build of today.

I removed the previous database by removing .kde/share/apps/amarok/mysqle
The collection is located on an external USB disk, formatted as ext3 and mounted at boot time.
Running amarok -d --nofork

The scanning stops at 85% and I have to stop the frozen application with Ctrl+C in konsole.  The Konsole output gives no useful clue on what is going wrong unfortunately. 

On restarting Amarok I have a collection showing up, which can be rescanned without new additions, but about 10% of my collection is missing.

I've renamed the report. "Importing" is confusing, as we also have a Collection Importer for Amarok 1.4 and iTunes databases.

So I changed it to "scanning".

Also CC'ing Dan Meltzer, as I know just how much he loves hacking on the scanner code.

Still have the same problem with 2.1-SVN:
http://amarok.kde.org/forum/index.php/topic,16839.0.html

*** Bug 189347 has been marked as a duplicate of this bug. ***

Adding Jeff to CC list, as he was the last one to touch the scanner code, IIRC. It's currently unclear if this one is a recent regression, or an old bug. 

Lately we've seen an increase of similar reports, which could however just be a result of the increased increased exposure of 2.1, due to the beta release.

Please note, I'm not saying that you have anything to do with this, but I thought that you might have an idea, as you've been working with the code more recently than most of us.

ScanManager.cpp is evil, that's for sure. Dan and I have already lost our marbles over it ;)

I've had this same problem since I first tried Amarok 2 Alpha 1. It produces the same freeze but at 97%.

The best thing that you guys could do would be to try to isolate what file(s) it's freezing/crashing on.  Take a look in ~/.kde4/share/apps/amarok for the various collection scanner files...one of them should have a list of files, and one of them should have the last file that was being scanned.

Try it manually as well -- try running "amarokcollectionscanner --help".  You probably have recursive searching on so you'll want to try something like: "amarokcollectionscanner -r /path/to/my/music"

Knowing whether the problem is in the collection scanner or the processor code will help immensely.  If you can isolate it to specific files, that will also help quite a lot if I can get my hands on them.

I've already tried with amarokcollectionscanner -r /path/to/my/music
and it works great. It scans all my collection.
Instead, in Amarok it stops everytime. If i select only some subfolders, it stops in different places, so it's not only ONE file.

Could some of you running 2.1-beta1 (or newer) please attach a full debug log here from a session where you are scanning the collection? You can obtain a log file this way:

amarok -d --nofork &> $HOME/amarok_scanning_debug.txt

I've made 2 different bug report, one of 50MB, and 70MB the other.
So this is only the last rows of the bug report:

You've tried a fresh database?

Yes, everytime I try I delete my amarok folder before it

Do you have playlists in your folders?  If so, what happens if you try scanning only folders that do not have playlists?

Created attachment 32972 [details]
Scan debug of 2 folder with mp3s

I have a LOT of playlist. All the albums and the singles I have, has a playlist inside its folder.
I tried with 2 folders of mp3s, and it stops at 87% but doesn't crash.
I attached the log.

I think I got a similar problem with 3 different versions of amarok:
2.0.60-svn Debian package
2.0.90 compiled from source and
2.1-svn

What happens:
Since I mounted a new harddrive to use it for data storage AmaroK always crashes when scanning my new collection which has moved from ~/Daten/Music to ~/DATA/Music while ~/DATA is the new harddrive/partition. ~/Daten was on my /home -partition.
Also I noticed that my old collection is still shown up but it is not posible to open it.
I hope this is helpful for finding the bug.

Here's the backtrace:

Sebastian, not sure you have the same problem -- that sounds like a dynamic collection problem.

Created attachment 34257 [details]
Debug output during collection scan

I just tried the new 2.1 and things are apparently getting worse. Right now, nothing of my collection seems to be visible. I couldn't manage to import my 1.4 collection either. It seems to work for a while and then stop. I attach the debug out.

Can I provide any more information? I'm afraid the shiny new 2.1 is in this state quite unusable for me.

I've spent the last 2 hours trying to make it work but it always crash creating the collection..
this with 2.1 final and svn locally recompiled , just in case.
I deleted all previous config files, nothing...I've started with a fresh user , same same...
no way. 

it dies with

this is repeted for a lot of files and /tmp is full with aborted sql stuff
I'm recompiling svn with debug symbols for provide a backtrace

this is after a complete new start:
by default amarok find something in my home scanning /home/user/music and that's ok
when I add another dir (in another partition) with recursive scan it crash with:

i had this issue too, but only on kde 4.3 trunk - it worked again with 4.2 - i know at least 2 ppl where the same applies...

Amarok debug output

I think I'm having the same problem.

Components:
-----------
Amarok2.1-SVN revision: 977716
mysql-embedded-5.1.34-1.fc11.i586
kdebase-4.2.85-1.fc11.i586
qt-4.5.1-13.fc11.i586
qtscriptbindings-0.1.0-5.fc11.i586

Description:
------------
Amarok crashes on start-up and it *looks* like it's hanging on the collectionscanner. Running the collectionscanner separately is not a problem. I'm now going to try to isolate every other suggestion in this bugreport.

Attached:
---------
Debug output from the command line.

Crash report:
-------------
Application: Amarok (amarok), signal: Aborted

- A single folder with a bunch of MP3 files and a cover doesn't seem to be a problem.

- With all files and folders added, collection_scan.files seems to be holding pretty much everything that's supposed to be in my collection. It looks like Amarok is still crashing on the scanner though.

Eelko, I don't suppose you can try it with KDE 4.2?

Jeff, not on this PC but I'll try to hijack a co-worker's PC. If I manage to squeeze out anything useful, I'll let you know. :)

Alright, I compiled Amarok on a Fedora 10 machine the same way I have on this F11 machine. 

The F10/KDE 4.2.3 machine seems to work fine, no problems while scanning and adding the almost the same collection as on the F11 machine (I copied the music over to the F10 machine).

It's about 80% of the music I have on the F11 machine. I accidentally deleted the other 20% on the F10 machine while cleaning up. I'd need to re-transfer and unpack a 4.5GB tarball for an exact copy which is a pain in the ass since it's a low-spec machine.

I could do an one-on-one copy by Monday (at earliest) since I'm running out of time now. Please let me know when this is desired. Otherwise I'd settle with these results. :)

*** Bug 195380 has been marked as a duplicate of this bug. ***

This is caused by the encoding probe code. I've fixed it. Please try the latest SVN version.

Closing the report.
Peter: if you fix a bug please remember to close the report =)

Gary

still crash on kde 4.2.90 , starting from a fresh user and clean conf
my collection is in another partition of the disk, I would reopen....

This is not the problem of KDE but Amarok. Are you using the latest SVN version?

yep, just compiled. Someone reports that works with kde stable
fresh installation crash on scanning , see
http://pastebin.ca/1450853

@Peter ZHOU

Unfortunately your commits does not seem to fix the problem for me. Conditions are the same as in comment #32 except for the Amarok revision obviously. I am now trying to run revision 978758.

This looks like a crash in Qt, or perhaps in its glib backend.  It would really help if you can isolate the file that it is crashing on and send it to mitchell kde org.

It DOES look like a crash in QT - BUT: the very same qt version with kde 4.2.3 works... 
Also it doesnt crash on particular files... its more or less random

Still present in current 2.2-git, Amarok freezes completely and has to be killed with Ctrl+C. It Always crashes at about 86%, but I can't identify any file that could be the culprit.

See also bug 191447 and 197782. Bug 196207 might give a hint, too.

@Eelko in comment 43: it looks like your problem is definitely bug 196207.

OK, found the origin of the problem:

My Music is stored in subfolders by artists. As soon as then scanner reaches the artists starting with "The..." it freezes and doesn't progress anymore.
Renaming these folders did the trick (removed the The of the name, e.g a folder previously called "The Rolling Stones" is now called "Rolling Stones".
I have found again the approx. 300 missing tracks, and the scanner proceeds correctly.

Closing as solved in current Amarok 2.2-GIT, build of today.
