digiKam 4.0.0 is out :

http://www.digikam.org/node/713

Please check if this entry still valid with this new version.

Thanks in advance

Gilles Caulier

We need a fresh feedback using last digiKam 4.2.0

Gilles Caulier

Sorry, can't help your request für testing in digikam 4.2. In Gentoo
repositories digikam 4.2 ships as "unstable" /masked.

As soon as I can update I will do so and report again...

Thanks for your help and interest.

best regards

Uwe Haider

ok, updated to digikam 4.2 and tested again...

First run of maintenance crashed again, but digikam was compiled without USE=debug so there was not enough info for drkonqi. I compiled digikam again with USE=debug and tested again -> no crash?!!
I have started digikam in terminal, so here is the last output:

Digikam was still running after that and shows no more active jobs...

Two additional infos:

1) My collection is on an external USB-Drive with 320 GB with no space left. I will try a new solution (NAS-Server)
2) Every maintenance-job is running a few hours... It tooks time to test - please stand by :-)

--------
Got some trouble with kipi-plugins
blending to HDR opens many windows, every new blending starts more windows and always with an error "could not safe". In fact the HDR is saved - just curios.

Making panoramas seems to start hugin but gets never to an end. After three days for an panorama with 24 pictures (made with nodal adapter) I stopped it... No idea what's the problem, starting hugin separately works fine.. for this I used my HDD, not the external USB_Drive (without free space).

That's all. If you miss some more detailed infos please don't hesitate to ask. I just don't know what to tell....
Next 10 days I'm on tour. After that I will try maintenance again.

Thanks so much for your help and patience

Uwe

digiKam 4.5.0 have been released.

Crash still reproducible with this release ?

Gilles Caulier

New digiKam 4.11.0 is available with official PKG installer for OSX.

https://www.digikam.org/node/740

Can you reproduce the problem with this release ?

With 4.10 the problem still exists. I have updated to 4.12 now and try again today...

digiKam 5.0.0 will be released soon.

Please test with this version quickly and give us a fresh feedback.

The latest (unstable) release for Gentoo / portage is 4.14.0-r1. The problem still exists with this release. The 5.0.0 isn't available for portage yet...
I will report.....

Just an idea:
Some pictures are tagged with names without a face selected. This is a relict from older releases. Newer pictures are tagged with marked faces. Perhaps this is a problem? Face recognition leads here to a crash too.

ok, I got digikam-5.0.0 now. The problem still exists. I have the stderr from zsh in a file with 622 MB. This are the last lines:

Do you think, the file will help?

A few problems are new:

- can't change to german
- no right bar in the album view (comment, tags, map etc...)
- no settings for the import, import doesn't work
- only 15 kipiplugins?

starting digikam leads to this message:
"Error message: The database is not valid: the "DBThumbnailsVersion" setting does not exist. The current database schema version cannot be verified. Try to start with an empty database."

This comes since updating to 5.0.0..

Thanks for your support....

uhai

1/ The crash appears in face engine. Sound a similar problem reported in this file :

https://bugs.kde.org/process_bug.cgi

2/ I18n : install digiKam translations packages.

3/ Install Breeze icon-sets.

4/ Idem 3.

5/ Most of plugins are migrated to digiKam core. It still only Web services tool in kipi-plugins.

That's it: max-allowed-packet was 4096. I set it to 16.777.216 -> facerecognition works first time ever :-))

But some error messages are still on:

How can I fix this? Can I set up the tables via phpmyadmin? Is there a doku for the db-structure? And how can I fill this hand made tables?

I will test the other functions of maintenance separatly an give feedback....

uhai

I couldn't solve all of the above mentioned problems:

1 - done
2 - no language pack l18n for digikam in Gentoo??
3 - Breeze icons are installed now, but some icons miss in digikam
4 - same

>That's it: max-allowed-packet was 4096. I set it to 16.777.216 -> facerecognition works first >time ever :-))

Where do you tune this settings exactly ?

Gilles Caulier

>How can I fix this? Can I set up the tables via phpmyadmin? Is there a doku for the db->structure? And how can I fill this hand made tables?

The errors come from Thumbnail database which can be broken due to previous crash. This database only contain wavelets compressed thumbs. You can drop it and recreate the database in mysql as at init. The database contents will be recreated automatically.

Gilles  Caulier

> no language pack l18n for digikam in Gentoo??

No idea. No Gentoo here.

At least, digiKam is released with whole translations pack. After, each packager make packages following distro rules...

in mariadb via phpmyadmin. (settings - max-allowed-packets) works fine.

maintenance thumbnails & fingerprints work - now testing duplicates....

uhai

I have finished  testing the maintenance modules:

- searching duplicates ok
- rebuild fingerprints ok
- searching new items ok
- thumbnails ok
- quality sort ok (but very slow - 2 days?)
- synchronizing metadata (both directions) leads to segementation vault & crash

Sorry, I can't see any error message for the segementation vault in the shell (zsh). How can I get the informations you need?

uhai

- quality sort ok (but very slow - 2 days?) ==> yes this part have never been optimized from algorithm side.

- synchronizing metadata (both directions) leads to segmentation vault & crash : probably some non re-entrancy with Exiv2 shared library. Did you use at least 0.25 release and disable multi-core support. Just to be sure. There are a lots of reports about this problem in bugzilla...

Gilles Caulier

Swati,

1/ We need to fix internal Mysql configuration file include with digiKam to set right value of "max-allowed-packet".

2/ In Remote Mysql Setup page Requirements, we need to add some words about this settings to be sure that end user will configure fine the server.

Gilles Caulier

> I can't see any error message for the segmentation vault in the shell (zsh). How can I get the informations you need?

Very simple. from a console, just run digiKam in gdb as explained here :

https://www.digikam.org/contrib

When it crash, the backtrace will be reported by GDB "bt" command.

Note : digiKam must be compiled with debug symbols.

Gilles Caulier

Thanks for your patience. I will build digikam with USE=debug today and test again.

Is this helpful for you? gdb is still running for further information....

uhai

ok, I have news for the exiv2 usage:

the gentoo package media-gfx/exiv2 isn't able for multi-core support. a friendly soul has checked the code :-) (thank s to firefly)

So the only way to multi.core support is the switch in digikams maintenance dialog - right? I don't use the switch because I have to work while digikam makes the maintenance....

Is this informaiton what you need?

Uhai

Thanks Uwe,

All backtraces indicate a problem with Exiv2 multicore/Multi-threads processing. This use case problem must be reported to Exiv2 bugzilla. There is no reason for these kind of dysfunctions while Exiv2 read or write from/to image files metadata.

>the gentoo package media-gfx/exiv2 isn't able for multi-core support. a friendly soul has checked the code :-) (thank s to firefly)

How this information have been verified exactly ?

So the only way to multi.core support is the switch in digikams maintenance dialog - right? I don't use the switch because I have to work while digikam makes the maintenance....

Yes. Disabling multicore support will run maintenance tools in a single CPU. It will be interesting to see if the Exiv2 dysfunctions are reproducible in this case.

Of course, One single core to run maintenance tools will be slower, as expected.

Uwe,

Metadata synchronizer maintenance tool will always use one cpu core now.

Please confirm that fix crash on you computer.

Also, we must have a real feedback from Exiv2 team about muticore cpu support in this library. Please report this problem into Exiv2 bugzilla as well.

Thanks in advance

This issue is no longer reproducible since the commit from Comment 37. I close the bug now, if necessary open again.
