Description Axel Krebs 2011-10-10 04:38:45 UTC 
Created attachment 64378 [details]
showing jpg and not opening NIKON (NEF) raw

Version:           2.1.1 (using KDE 4.7.1) 
OS:                Linux

For working on a restricted number of pics, I created a small folder including the desired pics. 

Even after re-opening ten times, digiKam thumbnail database increased(!!) in size instead of _de-creased_. 

When going back to my complete original full collection, a huge number of NIKON (NEF) raw pics did not open any more. Neither with digiKam, nor with raw-therapy of darktable.

Observed failure appears with older and new pics. 

Observation: re-opening of complete pic-collection took nearly 2 hours. 

Assumption: could be related with usage of tags. 

Reproducible: Always

Steps to Reproduce:
unfortunately: it is easily existent

Actual Results:  
unfortunately given

Expected Results:  
please provide a solution to save the pics.

OS: Linux (x86_64) release 2.6.38-11-generic
Compiler: gcc

I do not understand exactly this the procedure to reproduce this. But 
trying so I notice that where formerly an removed and reattached album 
scanned in short time, (just like scanning for new images) now it takes 
a looooong time. So this behaviour has changed. Deliberately?

Maybe it would be useful to provide raw-files working correct _and_ not opening versions?

If I send you both fils, that would mean about 16 MB size(!!) which exceeds my mail capabilities. (so: how to do this?) 

Could someone analyze these faults?

Please let me know. Thank you.

Could someone confirm this?

In my recent pics, I still observe this phenomena, even with new taken pics.
Is there a tool to check for (RAW?)picture integrity?

Showing NEF without preview after removing a tag

Additional observation: at the moment, I took a tag away, Nikon RAW Pics ("NEF") do not show a thumbnail anymore!

It takes just seconds, and previews disappear!

Comment 7 caulier.gilles 2011-10-30 19:33:50 UTC 
Sound like a side effect of Exiv2 which write metadata to RAW files. Do you use this option in digiKam metadata config. panel.

Which version of Exiv2 you use ? Go to Help/Components Info for details.

Additional information:

When "touching" NEF-Pics, thumbnail disappears, and I get message pic is not loadable. "Thouching" means _adding_ a (keyword-)tag _or_ _removing_ one.

Yes, I do use "write metadata in pic _and_ in XMP"

This is a super GAU (maximum credible accident <MCA>) for me.

I hope there is a solution.

Comment 9 caulier.gilles 2011-10-31 11:57:28 UTC 
Disabling Write Metadata to RAW file fix the problem for the future ?

If yes, well it's a problem in Exiv2 i think. I CC Andreas Huggel, who is Exiv2 author. I recommend to provide a NEF raw file before and after metadata modification for future investigations.

Also, this problem have been already reported in bugzilla and a solution to fix NEF files have been provided by Andreas.

Note : XMP sidecar option do not touch RAW files.

Comment 10 Andreas Huggel 2011-11-02 00:38:33 UTC 
I have received two sample pictures off-line from Axel:

Pic 1: DSC_4789.NEF - (original) pic, contains one tag "Tier"
Pic 2: DSC_4789_plus_new_tag.NEF - immediately after inserting the additional new tag "Belege"

Quick observations:

Pic 1 is not straight from the camera, it has been modified by digiKam and contains XMP tags (incl. tag Xmp.tiff.Software set to "digiKam-2.0.0-rc"), presumably added by exiv2. Thus it seems that exiv2 _can_ in general modify your NEFs without destroying them. It has the following tags with the value "Tier":

$ exiv2 -pa -u DSC_4789.NEF | grep -e Tier -e Belege
Iptc.Application2.Keywords                   String      4  Tier
Xmp.dc.subject                               XmpBag      1  Tier
Xmp.digiKam.TagsList                         XmpSeq      1  Tier
Xmp.MicrosoftPhoto.LastKeywordXMP            XmpSeq      1  Tier
Xmp.lr.hierarchicalSubject                   XmpBag      1  Tier


Pic 2 has a totally crippled structure. IFD0 is missing TIFF tags (that's what GIMP is complaining about), sub-image2 went missing, the makernote is no longer there and almost all Exif tags have disappeared. It has the following tags with the value "Tier" or "Belege":

$ exiv2 -pa -u DSC_4789_plus_new_tag.NEF | grep -e Tier -e Belege
Iptc.Application2.Keywords                   String      6  Belege
Iptc.Application2.Keywords                   String      4  Tier
Xmp.digiKam.TagsList                         XmpSeq      2  Tier, Belege
Xmp.dc.subject                               XmpBag      2  Belege, Tier
Xmp.MicrosoftPhoto.LastKeywordXMP            XmpSeq      2  Tier, Belege
Xmp.lr.hierarchicalSubject                   XmpBag      2  Tier, Belege


To verify if the problem is due to exiv2, it's best to reproduce the problem with just the exiv2 tool. However, I can easily add "Belege" as above to Pic 1 without corrupting it with the following command:

$ cat add-belege.cmd
add Iptc.Application2.Keywords        Belege
set Xmp.digiKam.TagsList              Belege
set Xmp.dc.subject                    Belege
set Xmp.MicrosoftPhoto.LastKeywordXMP Belege
reg lr http://ns.adobe.com/lightroom/1.0/
set Xmp.lr.hierarchicalSubject        Belege

$ exiv2 -v -m add-belege.cmd DSC_4789.NEF

The result is an intact picture with the "Belege" tags as in Pic 2 (except for the order in Xmp.dc.subject):

exiv2 -pa -u DSC_4789.NEF | grep -e Tier -e Belege
Iptc.Application2.Keywords                   String      4  Tier
Iptc.Application2.Keywords                   String      6  Belege
Xmp.dc.subject                               XmpBag      2  Tier, Belege
Xmp.digiKam.TagsList                         XmpSeq      2  Tier, Belege
Xmp.MicrosoftPhoto.LastKeywordXMP            XmpSeq      2  Tier, Belege
Xmp.lr.hierarchicalSubject                   XmpBag      2  Tier, Belege


So this doesn't look like an exiv2 issue. Please provide the steps to reproduce it with just exiv2 (a reproducer program or the command line tool), if you think it is.

Hi Andreas: 

thank you checking the matter. Sorry for ansewering late- my workday starts at 7 a.m. and end ~9 p.m.

I provided two pics according to Gilles` suggestion.

Pic 1: DSC_4789.NEF - (original) pic, contains one tag "Tier". I took this as appearantly "unchanged", as I never had problems with tags in NEF in earlier digiKam version before.

I do not understand, what 4 "tags" should mean: 4 independant tag with the same content "tier" (maybe not really important?)

Pic 2: DSC_4789_plus_new_tag.NEF - immediately after inserting the _additional_
new tag "Belege". I copied that pic, added the mentioned additional tag- and got problems. So the _basic_ pic content is identical. You call it "totally crippled structure".
 
And this make me wandering: as both pics are definitely the same, I do  not understand, wher this tagf-mixture should come from. 

As common sense indicates, certainly not from an additional treatment in my camera.

Maybe it helps you understand my regular workflow:
- Taking the picture. 
- Basic setting NEF plus jpg, usually DIN 100 sensitivity.
- copying the pics from SD-Card to PC
- starting digiKam, sometimes starting "search for new pictures"
- then immediatelly tagging all new pics for some tag-types as "Tiere", "Freunde", etc.
 
- there is only a flat hierarchical structure on two levels. 
- as I developed the tag-structure over some couple of years, the very tags stay stable and will not be changed later.
- I showed my recent database statistics

- Before the recent digiKam version, I had 
- the same settings- and did _NOT_ experience problems.
- I had the same camera (NIKON D60)- no changes

For me, there seem to appear _two_ changes:
1.) new digiKam version
2.) as described recently, I desized my digiKam database (from 145000 pic to 7800 pics) and included only relevant branches (=directories) I assumed to be necessary to prepare a selection project. 
As I mentioned before, too, digiKams thumbnail database would keep its size even after several booting procedures over three weeks or so.  If self cleaning feature within databse would have worked prooperly, the thumbnail database shouöl have decreased from 6,7 GB (for 145000 pic) to 360 kB size at 7800 pic.

This is certainly not correct, or?

You mention:
...
Xmp.digiKam.TagsList                         XmpSeq      2  Tier, Belege
Xmp.dc.subject                               XmpBag      2  Belege, Tier
Xmp.MicrosoftPhoto.LastKeywordXMP            XmpSeq      2  Tier, Belege
...

Why the sequence of tags changes? 
Is there a sequence problem involved? 
Why are there three more lines than in pic 1?

You suggest to test exif 2 , if writing tags correctly. Since last digiKam update I run KUBUNTU, and semantic desktop may run too. 

How do you exclude cross-relationships from that side? By checking the "naked exif2 tool"?

You ask me for the steps to reproduce. It sounds to me a like asking a bird for how a plane does function... I am npo programmer. And I do not know, which informations are relevant for a programmer. Thats why I am not really sure, how I can support you. 

Please let me know.

Thank you-


Axel
Comment 12 Andreas Huggel 2011-11-03 01:24:54 UTC 
Hi Axel, you don't need to be a programmer to provide further support to resolve this.

Gilles made a qualified guess that this looks like an exiv2 problem, but I can't reproduce it here, so I'm passing it back to digiKam.

Next, a digiKam developer should try to reproduce the issue with digiKam. You can help by describing the exact steps to perform in digiKam to get from Pic 1 to Pic 2 (if that's not clear yet from all the comments above). Once reproduced, it can be analyzed and we'll know exactly where the problem is.

Axel,

I tested on my computer with digiKam 2.3.0 and co with your original NEF image.

I create a copy of NEF where i apply some tags. Write metadata to RAW files option have been enabled previously. I use Exiv2 0.21.1, and libkexiv2 2.1.0.

The problem is not reproducible. Modified image is not corrupted, can be previewed, and opened in image editor without problem.

I will attach some screenshots from my computer.

Comment 20 caulier.gilles 2011-11-03 10:59:24 UTC 
Rinus, I recieve NEF files by private mail. I CC you...

Comment 21 Rinus Bakker 2011-11-03 17:42:55 UTC 
Provided info by Axel Krebs:
¨My digiKam database was quite large- 140000 pics, 6,9 GB size(!!). As I
knew I have to work intensively with that database, I created a
selection of only 8000 pics to gain some loading speed.

Instead of getting smaller after some loadings, it kept this size and
loading "speed".

After some weeks, I included all other pics, I had outsourced before.

In "digiKam settings ->  collections" I added those pics by selecting a
(sub-)directory, which are stored in a number of directories.
---

No I got problems: while tags had been set up hierarchical before, they
look meshed up now. Have a look at tags "auto" and "quasimodo" in
enclosed pic.

As the structure was correct before, I am quite sure that the internal
structure of database might be corrupt.¨


##############################################################
Start trying reproduce according info supplied by Axel Krebs
##############################################################

I start making a copy of my db containing my art collection.
digikamdb 229 MB
thumbnails 4,9 GB
number of picture 136043
number of albums 5567
number of tags 1248
startuptime 145 seconds. second startup 98 sec.

	This looks from the quantitative perspective more or less comparible setup

I put the NEF in one of the art folders
It opens normal
add some tags
it still opens normal with image editor and with gimp
add another tag
every thing still normal

Now I go removing albums, but it appears that I can not remove a subalbum(directory) without actually deleting it.
So I have to make a second root album ¨ARTtest¨
Move several subalbums to ¨ARTtest¨ and remove my main root album ¨ART¨ from settings->etc
I close dk
reopen digikam

digikamdb 229 MB
thumbnails 3,8 GB (This is changed but much larger than expected)
number of picture 29635
startuptime 20 sec (this is different from Axel´s experience)

Now I add under settings->configure dk etc several subalbums that formerly has been under the rootalbum ¨ART¨ to the new ¨ARTtmp¨

I can not detect any changes in tag structure
Tags in NEF are still as before
NEF can still be opened normaly.


Axel, what do you think I should do differently to reproduce the problems?

I wonder about a few things that maybe could be related.
Can there be something wrong with harddrive?
Did you test db integrety as I suggested?

Will be happy to do further investigations if I only had a clue how to went on.

Can a corrupted db be due to corrupting NEF? Does someone know the answer?

Strangs tag-names, isn´t it? I was never with a digital camera in USA/CanyonLand!

I just remember, I saw sometimes (=in different digiKam versions) tag, I had never ever used or even created before by myself. One "flower"  my feeling was this contributes to some fancy ( .. ) stuff of semantic desktop. 

When I reported on a folder named "people", I got to know, this was due to compatibility reason or so (Marcel Wiesweg?).

Hi Rinus:

thanks!

1.) "What could we do": one idea: is it possible to test database _and_ digiKam _without_ "semantic desktop" (akonadi-server and similar stuff)?

2.) defect hdrive? a hidden failure could happen everywhere... but installation, pics _and_ database are on my boot hdrive whch is running nicely  and beeing checked "ok"

3.) Another Consideration: digiKam offers to apply several settings to be checked, as exif, xmp iptc. I always activate _all_ crosses. And I cross install _into_ Nepomuk, _never_ from Nepomuk _into_ digiKam.

Maybe there is a filed size problem or a limited number of crosses allowable? waht would happen, if the total amount of tags  digiKam handles do not "fit" into a picture"?
What happens, if Nepomuk fails writing tags correctly into its database?
Or data-exchnge between pics and Nepomuk is questioned?

Is there an independant way to check integrity of thumbnail and tags databases?
Is it possible to check the content of those databases comapred to all pics´ content?

Checking database integrity:

Following a hint of Rinus, I did check and "clean" digikam4.db _and_ thumbnails-digikam.db .

Sizes                     Before                After
digikam4.db                501,3 MB            221,3 MB
thumbnails-digikam.db      6,7 GB              6,7 GB

Both databases were checkes to be status "ok"

Repeated intensive Harddisk-drive check over hours, using GSmartControl 0.8.6 : every specific test criteria has been proofed to be without eror/mistake.

Why is there a distinction between NIKON-NEF and RAW-NEF???

I always assumed that NEF means "Nikon Electronic Image Format", so what means "RAW-NEF"?

If I assume, that digiKam statistics base on automated procedures, I have to conclude, that digiKam only recognizes 364 pictures as NIKON RAW-Format (out of 36168). 

Something is strange, I believe. Am I wrong?

The right value is RAW-NEF in DB stat. NIKON-NEF is probably an internal ID used in beta version. Now all is RAW-NEF.

Comment 30 Axel Krebs 2011-11-05 08:36:03 UTC 
Thank you for informtion, but _what_ is "NIKON-NEF"?

Asking because I fear there might be an ambiguity not limited to field
names (or so), but also for internal procedures. This could extend
potentially on "my problem"

Comment 31 caulier.gilles 2011-11-05 08:41:38 UTC 
NIKON-NEF = RAW-NEF

In database, NIKON-NEF must become RAW-NEF.

Do you tried to start digiKam as new instance a clean database to see if problem disappear ?

An idea: if you are able to confirm that the NIKON-NEF´s are the damged 
ones. Then they might open by the betaversion you have formerly used on 
them.
Now, just to know if this is the case, and if, which beta version was on 
your computer at that time. But I guess for a rebuild you need to have 
all the dependencies of that specific build wich is impossible I guess. 
And I am worried about the missing 866348 bytes. And how is metadata 
stored in NEF, at a specific location?

>And how is metadata stored in NEF, at a specific location?

As a lots of RAW file format, NEF is based on TIFF/EP format. metadata are stored in a dedicated place to store Exif/IPTC/XMP tags. Andreas can explain more in-deep the format if necessary...

Are there new developments?

In the last three weeks I used fantastic autumn wheather to shoot ~4000
pics... (http://en.wikipedia.org/wiki/Inversion_%28meteorology%29 ,
http://www.schwarzwaldhochstrasse.de/31-1-Hornisgrinde-and-Bismarckturm.html
, sight to the Alpen, Berner Oberland Eiger-Mönch-Jungfrau, 350 km
distance!!)

Can I trust digiKam now, not to damage my NEF-pics?
Can I be sure about digiKam?
Is there a check, a procedure to deal with this issue?

Hope urgently for a solution
