1.0 [7.110]: XnViewMP browser ignores certain jpg files

[jotess]

XnView: MP 7.110 [edit:] 1.0 - 64 bit
OS: Windows 11 Pro 64bit

In the browser, certain jpg files are not displayed. The Status bar says "0 objects" although there are images in the folder. I could not find out yet what might be different about files that are displayed or not displayed.
Here are at least some findings (or mostly not-findings)

• The problem did not occur in v. 7.100 [edit:] 0.99.7 an when I re-install v. 7.100 [edit:] 0.99. everything is normal again. Install 7.110 [edit:] 1.0 again and the problem is back.
• It seems not to be a question of filter criteria. It happens no matter if I select "images" or "all" or anything else.
• The bug seemed to concern whole folders - but it doesn't necessarily. To check this, I copied a jpg that appears in the browser (i. e. from a folder that seems not to be concerned) into a seemingly empty folder. This jpg is displayed in that target folder. All other previously contained jpgs in the target folder are still ignored.
• The files are all from the same two cameras: My Samsung phone and my Panasonic DMC-TZ-101. And usually they are unmodified except IPTC data. But the problem also affects virgin files downloaded straight from the device. There is a folder containing files from my camera and a friend's camera. His files are displayed, mine are not.
• It seems not to be a problem of filenames or paths (like spaces, umlaut characters, path length)
• It seems to concern only jpg files, not raw, but this might be just a coincidence that I haven't come across the problem with raws
• I can open those ignored files via File|Open. But when I select Image|Properties (Alt+Return), nothing happens.
• When I rename concerned files in Windows Explorer (e.g. by simply adding one character) while the containing folder is open in XnView MP browser, they become visible. Reverting this makes them invisible again in XnView MP. Selecting a different folder while the (once) renamed files are visible and going back to the problem folder, then the files are ignored again.
  To make it clearer here an example:
  In d:\pictures\problemfolder\ there are two images: 1.jpg and 2.jpg
  Open that folder XnView MP browser: "0 objects"
  Open Windows Explorer, rename 1.jpg to 1x.jpg -> 1x.jpg becomes visible in XnView
  Revert rename -> 0 objects in XnView MP
  again:
  In Windows Explorer, rename 1.jpg to 1x.jpg -> 1x.jpg is visible in XnView
  Select any other folder in XnView MP browser and select problemfolder again -> 0 objects
  In Windows explorer rename 1x.jpg to 1.jpg -> 1.jpg becomes visible in XnView MP.

To reproduce:
You would probably have to try with my files. I can provide some.

Actual behaviour (bug): Browser shows no images and "0 objects" in status bar

Expected behaviour: Browser shows all files matching filter criteria

Thank you, Joachim, for your long and detailed problem report. Current version of XnView MP is v1.0 while you are talking of version 7.110. Where does this difference come from?

Help > About

Unexpected also for me...

[jotess]

Oh, sorry! I noticed the Libformat version first and didn't look further. Problem occurs in 1.0 and doesn't in 0.99.7.
Edited my first post for clarity for future readers.

[xnview]

what do you have in settings>File list?

In d:\pictures\problemfolder\ there are two images: 1.jpg and 2.jpg
Open that folder XnView MP browser: "0 objects"

you can reproduce each time???

[jotess]

My settings are:

2022-06-21 20_34_33-Settings 1.png (14.96 KiB) Viewed 1418 times

2022-06-21 20_32_28-Settings.png (20.65 KiB) Viewed 1418 times

And the settings are the same I guess, for both versions of XnView. In other words: I didn't touch the settings, I just updated from v. 0.99.7 to 1.0 and the problem occurred. And I reverted to the old version and the Problem was gone.
Yes, the effect is absolutely reproducible.

1st test
Can you try to change the first setting (file list) "Recognize only by extension" ?

2nd test
Change last setting in custom filter
"Include" , let the checkboxes unchanged, but try to delete jpg

3rd test
Close xnviewmp , rename the file thumbs.db as thumbs.old, and restart xnviewmp
(You can locate thumbs.db in Settings>Intergration>Paths)

Still same behaviour ?

[jotess]

Re-installed 1.0, tried all three tests -> no change in behaviour.

[xnview]

could you enable 'show companion files'?

[jotess]

This works! How come? Does XnViewMP consider some of the images companion files after the update?
And is there a workaround? Because I usually don't want to show actual companion files.

I can't reproduce, could you send me your xnview.ini?

in the companion settings, you have jpg => {ext};exf, please remove {ext}

[jotess]

I can't seem to find what you mean. "Companion settings" must be in line 875:

Code: Select all

[Companion]
useForDelete=true
useForOther=true
list="@Variant(\0\0\0\v\0\0\0\x2\0\0\0\n\0{\0r\0\x61\0w\0}\0\0\0\"\0{\0\x65\0x\0t\0}\0.\0x\0m\0p\0;\0x\0m\0p\0;\0j\0p\0g)", @Variant(\0\0\0\v\0\0\0\x2\0\0\0\n\0{\0r\0\x61\0w\0}\0\0\0\b\0l\0m\0n\0r), @Variant(\0\0\0\v\0\0\0\x2\0\0\0\n\0{\0r\0\x61\0w\0}\0\0\0\x6\0p\0p\0\x33), @Variant(\0\0\0\v\0\0\0\x2\0\0\0\n\0{\0r\0\x61\0w\0}\0\0\0\x6\0o\0n\0\x31), @Variant(\0\0\0\v\0\0\0\x2\0\0\0\n\0{\0r\0\x61\0w\0}\0\0\0\x6\0\x66\0p\0\x31), "@Variant(\0\0\0\v\0\0\0\x2\0\0\0\x6\0j\0p\0g\0\0\0\x12\0{\0\x65\0x\0t\0}\0;\0\x65\0x\0\x66)", "@Variant(\0\0\0\v\0\0\0\x2\0\0\0\x6\0\x61\0r\0w\0\0\0\"\0{\0\x65\0x\0t\0}\0.\0x\0m\0p\0;\0x\0m\0p\0;\0j\0p\0g)"

The only other place that seems relevant to me is:

Code: Select all

[Browser]
viewAs=6
sort=6
sortOrder=1
mixFileFolder=false
showHiddenFiles=false
showCompanionFiles=true
filter=0
customFilter=3589
thumbnailFilter=2641
custom1Ext=htm, html, mht, mhtml, xml, xhtml, eml, nws, url, svg, svgz, dng, raw, arw, rw2
custom2Ext=jpg
sizeInBytes=false
...

Nowhere in the file I can find " jpg => {ext};exf,".

Settings>File list - companion

[jotess]

That was it, thank you!
I would like to know, how that "{ext};" got there. And why this affected only some jpg files and some not.
