Description Olli Lupton 2016-07-14 16:52:22 UTC 
Digikam consistently crashes if I remove (right click, "Delete Tag") a tag in the tag manager (2nd tab, left hand side of screen). This happens regardless of whether or not the tag is applied to any images.



Reproducible: Always

Steps to Reproduce:
1. Install http://download.kde.org/stable/digikam/digiKam-5.0.0-MacOS-x86-64.pkg
2. Go to tag manager (2nd tab on left hand side of screen)
3. Right click on a tag and click "Delete Tag"

Actual Results:  
Crash.

Expected Results:  
Tag should be removed from all files it is applied to, and the tag should be removed from the list.

Comment 1 Olli Lupton 2016-07-14 17:05:38 UTC 
Two further comments:

1. The operation does seem to succeed (i.e. the tag is removed), despite the crash.
2. I see a similar crash if, in the tag manager, I try and move a tag (e.g. SomeName -> People/SomeName).
Comment 2 caulier.gilles 2016-07-16 05:34:10 UTC 
Which database type do you use ?
Where is stored your database file (in case of Sqlite) ?
Where is stored your collection ?
Can you run digiKam from a console to see all debug statements printed before to crash ? digiKam executable is installed in /opt/digikam/Applications/KF5/digikam.app/Contents/MacOS/digikam

Gilles Caulier
Comment 3 caulier.gilles 2016-07-16 05:35:56 UTC 
Note : I cannot reproduce the crash here. I can play with tags in tree view as well (move, remove, create, rename, etc...)
Comment 4 caulier.gilles 2016-07-16 14:01:33 UTC 
Also which type of database you use ? sqlite or mysql ?

I tried with both and i cannot reproduce the problem...

Gilles Caulier
Comment 5 Olli Lupton 2016-07-16 17:24:59 UTC 
Thanks for looking into this!

Database type: SQLite (created with digikam 4.X)
Database location: local SSD
Collection location: local HDD (machine has 1 SSD, 1 HDD)

I ran in a terminal as you suggested. The only output triggered by deleting a tag is:

digikam.geoiface: ----
digikam.geoiface: ----
digikam.general: Stacked View Mode :  0
digikam.general: Delete Shortcut assigned to tag  610
digikam.geoiface: ----
Segmentation fault: 11

Which doesn't seem that informative to me. In case it helps, here are the first few lines printed by digikam after startup. Let me know if there's anything else I can try?

Comment 6 caulier.gilles 2016-07-16 19:34:04 UTC 
I suspect something wrong with old sqlite  database files.

Please rename these files es *.old, and recreate the database from scratch.

Gilles Caulier
Comment 7 Olli Lupton 2016-07-18 17:29:27 UTC 
Hi,

I just tried as you suggested, re-naming the database files and letting it rebuild them.

This does not fix the problem. I removed a tag and it crashed again, see below.

Is there another way of running the OS X packaged build in some debug mode that would provide more useful information?

Comment 8 caulier.gilles 2016-07-18 18:27:56 UTC 
Debuging under OSX is not too simple as Linux or Windows.

I tried, as Windows version, to include GDB, but it prohibited to attached process to debugger without to sign GDB to Apple service. It's for security reason (as Apple said).

Alternative is to patch internal settings from OSX and restart it. But it's not sure that it work with last OSX version.

The most simpler way, is to use a debugger already signed and available in AppStore.

Here i use XCode, I start digiKam, and i attched the process to Xcode debugger. There are few command in Xcode menu to use. It's simple. After that, you use digiKam until it crash. XCode will indicate where process is stopped in code with the call backtrace.

The problem is that XCode is a huge package to install. I don't yet tried to check if a small debugger exists in AppStore.

Comment 9 Olli Lupton 2016-07-18 20:25:33 UTC 
I tried catching the crash with Xcode, but there is very little information there.
Are the precompiled bundles on http://download.kde.org/stable/digikam/ supposed to have debug symbols?  Xcode just shows the instructions, which are rather unhelpful.

yes digiKam bundle must have debug symbols.

Give me more information about your collection. Where are stored your images ? Which kind of images do you use ? JPEG, RAW, TIFF ?

10.11.5 here, but i have a VM with 10.11.4 to test and no crash.

Can you check if crash also appear using Album GUI right sidebar in Caption & Tags. Just go to tags tree view and delete a tag.

Gilles Caulier
Comment 15 Olli Lupton 2016-07-19 19:14:34 UTC 
Hi,

I just tried, I get the same crash using the GUI on the right-hand-side as well.

I have tried experimenting with a clean database + 1 blank-white JPG created in an image editor (=> no tags initially)

Remove DB files -> start digikam -> choose collection location -> add tag (Test) to file (gives 'Tag name already exists' error but apparently succeeds) -> Apply -> close digikam -> restart digikam -> (tags list now shows 'People' in addition to 'Test') -> delete 'Test' -> crash

This crashes reliably for my main user account.
I tried to replicate in a 'clean' user account on the same machine, but there the same prescription does not crash. I am, therefore, wondering if there is some bit of old configuration lurking somewhere that I am failing to clean up, and that is causing the problem (somehow).

Currently to make a 'fresh' start I am deleting the three .db files, and removing ~/Library/Preferences/digikam*
Is there some other configuration or cache hidden somewhere else?
Comment 16 caulier.gilles 2016-07-19 19:32:02 UTC 
Hey, you have completely right.

Older settings has already crashed digiKam for other users while beta stage.

This is why we have not yet backported older settings in new version. Typically, older settings are in separated place, so no conflicts are possible, at least under Linux. But under OSX, sound like different.

Look my comment here where i explain where are stored digiKam settings files :

Comment 17 Olli Lupton 2016-07-20 13:25:32 UTC 
Hi,

I made sure all of those locations were removed, but it doesn't stop the crashes using my main user account. I also tried removing:
~/Library/Saved\ Application\ State/digikam.savedState/
~/Library/Caches/digikam/
~/Library/Application\ Support/digikam/
along with re-removing the .db files, and I still get crashes.
Can you think of any other possible persistent configuration or caches?
Comment 18 caulier.gilles 2016-07-22 06:44:44 UTC 
No, i think you have all the files listed here. The most important is digikamrc file.

But i suspect that the digikam4.db file has something wrong. Here i have an iMac with digiKam 4.12 installed where i upgraded to 5.0.0. After migration, using older sqlite DB, i see the path of main collection with strange characters in Setup/Collection page. Do you have the same problem ?

Hi,

Sorry for the delay.
I also saw strange characters in the collection paths when I migrated by 4.X database to 5.X, and had to re-add the collections to fix this.

However, this does not explain the crashes I have seen. I was able to reproduce the crash in a fresh 5.X session (having deleted the .db files and all the configuration files I know about).

The fact I am not able to reproduce the crash using a different user account on the same system suggests to me that the problem is either that there is some other old configuration file I don't know about, or digikam is somehow being affected by environment of one of the user accounts (PATH,DYLD_LIBRARY_PATH etc.).

None of them. digiKam is packaged as a stand alone bundle application.

when you said that it do not crash with a new account, do you point the same collection and the same DB files than with suspicious account ?

What's about right access to DB file with the problematic account ? User is in the right group with the the right than good ones ?
The DB file/dir can be open in RW by problematic account ?
What's happen when you create the DB in another place with problematic account ?

Apologies for not following up with this.

I am now on 3.6.0 and no longer see this bug.

Since I could reproduce it I had to rebuild my library from scratch, so it's not clear whether the newer digikam version actually fixed the problem, or if was due to funny state of the database.
