Thumbnail view with the incorrect file size.

Version:           2.0.0 (using KDE 4.6.4) 
OS:                Linux

When showing the thumbnails of big files (.MOV files from a EOS 60D) the file size shown for the files >2Gib is not correct, and shows as 16EiB.

Reproducible: Always

Steps to Reproduce:
Import files bigger than 2Gib into Digikam, and open the thumbnail view with the thumbnails showing the file size.

Actual Results:  
Files greater than 2Gib incorrectly report the file size as 16Eib.

Expected Results:  
The thumbnail should show the correct file size.

This is an ls -ls with the size of the original files:

-rw-r--r--  1 joseluis joseluis 2845517348 2011-06-07 12:28 MVI_1379.MOV
-rw-r--r--  1 joseluis joseluis 1527880952 2011-06-07 12:37 MVI_1380.MOV
-rw-r--r--  1 joseluis joseluis 2648664444 2011-06-07 12:54 MVI_1381.MOV

Attached is a capture of the thumbnails.

This bug was showing in Digikam 1.9.0 and after updating to 2.0.0~rc1-natty~ppa1
 from Phillip's PPA, it is still happening.

Dolphin give the right value if you try with it ?

Dolphin showing the correct file size

I don't usually use Dolphin but Konqueror, but I understand that they use the same libraries. Anyway, I opened Dolphin and the correct file size is shown in the right panel and in the Properties window.
Comment 3 Marcel Wiesweg 2011-07-11 15:41:24 UTC
Quite simple: The filesize is stored in an integer, at some places even a signed integer.

It is straightforward to change fields to qlonglong on the C++ side. Question is if the database is ready to store a longer value. With SQlite, the field is declared as INTEGER but that apparently also allows 64bit values.

Francesco, what about MySQL?

sqlite is ok:
INSERT INTO "Tags"
VALUES(9223372036854775807,9223372036854775807,'PIPPO',0,NULL);
SELECT * FROM Tags WHERE id = 9223372036854775807;
delete from Tags where id = 9223372036854775807;

nope mysql has different types for 32 and 64 bit integer (and has a few more
for smaller ones), one of the things I want to do with next revision of the
database is to change many fields from type INT to BIGINT, if needed I can do
it for 2.0 but cannot suggest it.

mysql> INSERT INTO Tags
VALUES(9223372036854775807,9223372036854775807,'PIPPO',0,NULL,0,0);
Query OK, 1 row affected, 2 warnings (0.02 sec)

what does digikam use the size for? If it's only a display thing we can fix it
in c++ for sqlite users and correct mysql database for 2.1

Sounds good. It's used for display, identifying files and thumbnails in combination with a hash, and triggering a rescan.
But files >2GB are still a corner case in the year 2011, so it's not that urgent.

Use qlonglong for file size in C++

This does not yet fix the bug:
The binary protocol of the ioslaves will have to be changed.
I have avoided this so far, but plan to do it.

As well, this change needs to be evaluated for MySQL as discussed by Francesco.

Make file sizes >2GB work with SQlite without changing ioslave protocol

To avoid changing the protocol, any 31bit-value will be passed from the ioslave,
any larger value will be reread from the main application.
For large file size support in MySQL, a schema change is needed.

Jose,

There are a lots of commits from Marcel to fix this issue. 

Problem still here using digiKam 2.4 ?

Digikam 2.4.1 showing the bug

Sorry, I've just installed 2.4.1 from phillip5 PPA's (I was still at 2.3.0) and the problem is still happening :S
Comment 10 caulier.gilles 2011-12-15 11:48:16 UTC
The size of file information are already registered in database. You need to refresh these information.

Just to test, create a new account on your system, run digiKam and import files. Look is size are parsed and stored properly in database.

Digikam 2.5 showing the bug

Awfully sorry for the delay, I've been abroad for christmas and couldn't try.

Unfortunately, bug is still happening with 2.5 from phillip's PPA.

- Created new user with default kde config
- Open digikam with default options (Next > Next > Next > Finish), so SQLite DB, I suppose.
- Open konqueror and drag the videos into Digikam (thus copying into the new user's collection).
- Select album, with same result. Screenshot attached.
