XnView Software

I have just noticed that for JPEG and TIFF with IPTC data, the thumbnails are not correctly cached.
(but... THM files with IPTC are correctly cached)

How do you verify and see that caching does not work?

By switching from an empty directory to my main directory, most thumbnails are displayed immediately (JPEG/TIFF without IPTC) except those: I can see the Thumbnails of the TIFF/JPEG with IPTC appear one by one...

If I create and add IPTC fields to one JPEG that was previously correctly cached, and do this switching again... it will appear slowly too.

Did you try optimize?

I had tried 'Optimize' without any result...

I then have deleted the cache for this directory to see the changes:
- I switch directory and come back => all thumbnails are slowly regenerated. Normal.
- In the Cache, it says: 550 images are cached... whereas there are only 62 objects (no multiple TIFF, GIF, PNG or...).
- Each time I switch back, XnView adds 8 images to the cache of this directory (and there are 8 images JPEG/TIFF with IPTC, slowly regenerated) => 558, 566, 574 images in cache, etc...

I have some pdf, cr2, crw, thm, dng, html, lnk in the same directory that may affect this strange behaviour...
...I will try in another empty directory with only TIFF/JPEG files with IPTC.

I copied one by one all my files from the main directory to a subdirectory to try to isolate the problem... => no problem in this directory (right number of images cached, no slow regeneration, etc...).

I then deleted all the files in the main directory (it was "E:\"), and moved one by one all my files from the subdirectory back to the main directory... and everything worked perfectly there as well !!!

Summary: I had issue with images in "E:\", moved them in a subdirectory with XnView, moved them back in "E:\" with XnView ... and the problem is completely gone (and I can't reproduce it). Strange...

If you want to investigate further, I can try to help... but it looks like the issue is closed, now.

Perhaps a problem in the DB files????

Maybe...
In the Options>Browser>Cache, I did a "remove all" and then changed the Cache directory soon after installation, several days ago - I did not notice any issue at that time but... maybe the problem was already there, and moving the files solved it ?

Note: I moved it from the Default (I don't remember what it was) to "E:\=Cache" (same HD, 3rd NTFS partition).

Hourra! Pierre: I have this problem again...

What should I do ?
Send you the corresponding .db file ? the .ini ? any image ? or... ?

Could you send a folder with picture with the problem, and send me your .ini too.

Pierre,
If I copy the folder with Windows Explorer and use XnView to check this new folder, I don't get the problem anymore. Therefore, you will not be able to reproduce the problem directly with the files (ie: they are probably not problematic per se).

I have uploaded some files on my website to show the problem:
(all thumbnails have already been created and cached)
- When I open the folder, some thumbnails are immediately showed while others are being re-created (see this screenshot just after selecting the folder: 5 images are properly showed). After completion, all thumbnails are showed (screenshot).
- You can also check the variation of files cached: with 450 images and with 522 images after 3 more viewings (29 Thumbnails - 5 properly handled x3 => +72) while the folder was not modified at all.

You can download here: 1 image not properly showed + my XnView .ini file + the cache file of the problematic folder.
Maybe you can find something in the DB file itself (check some reference issues, identical file names, etc...) ?

PS1: I deleted the cache file with the options... and the problem disappeared again.
PS2: I currently use my system to test several softwares and some of them do not work as expected => this problem may be caused by some third-party software. I will soon revert to a clean image of my system and see how XnView behave...

I still had the problem in XnView 1.82.1: some images were cached several times, creating doublons, triplons, etc... although they were already in cache...
(I think I even had one cached folder with thousands of cached items, for only 100 files or so - and nothing changed meanwhile in that folder... )
Same issue is described here.

Next release use a new cache system, with a true DB

Nice...
Thank you, Pierre.
