Fixed NextcloudKit 2.4.0

[hardingt]

@marinofaggiana does reference the following? nextcloud/NextcloudKit@9154418

I'm not a swift developer, but I'm not seeing any reference to a time header. Also, if it's another commit that I'm not seeing here, when would this make it's way to the iOS app?

If it helps at all, the left is an image that DID load just fine, and the right is an image that has the X-OC-MTime issue. The difference here is the left photo was taken with this iOS device, and the right was not, but was loaded into the iCloud. This seems consistent with all of the errors.

[AngryAnt]

The bug persists.

iOS app 4.8.6.4
Nextcloud 27.0.2

A bit unclear here mid-operation: Is this resulting in failed transfers? I intend to fix fs timestamps post-upload anyway, but this is part of a migration and I would hate to in a couple of years discover that this bug cost us precious family photos.

[mike12806]

Issue is still happening for me too…

[devonkinghorn]

I still have this error

[hardingt]

And yet this issue is still closed, might be good to make a new one @devonkinghorn , not sure the devs are going to revisit this ticket again :(

[marinofaggiana]

witch version of Nextcloud iOS you use ?

[hardingt]

4.8.6.4 on my end, same issue. It's for older photos which don't have that particular header in the exif data (my assumption)

[marinofaggiana]

can you update ? we are to 4.9.2

[devonkinghorn]

I was on the latest on the App Store. I just saw 4.9.2 was released yesterday and barely updated. Same error message

The server version is "Nextcloud hub 6 (27.1.3)"

[hardingt]

Just updated to 4.9.2

[marinofaggiana]

ok, REOPEN

This weird photo of what looks to be a memorial (I took it 13 years ago, no idea) is free for y'all to use for testing, it produces this error for me.

One thought that did occur to me, after looking at the EXIF data, which looks fine, (nothing obviously different to me), is perhaps this only affects uploaded photos or non HEIC photos? Photos that the iPhone took itself seem to be the only photos working.

[marinofaggiana]

about the Photo we look the creationDate content the iPhone asset not the EXIF data

[marinofaggiana]

you can try the version in TestFlight if solved

https://testflight.apple.com/join/RXEJbWj9

[devonkinghorn]

I think the version in test flight worked. Let me finish the sync and check for any lingering issues

[devonkinghorn]

Update: The sync works. It puts photos and videos in the correct folder partitioned by month. But in the media tab, the dates are way off. Photos from 2012 are showing up today.

The negative time is the date before 1/1/1970 and this date are not accept from the server, so if the ctime or/and mtime of photo is negative I don't send the date, so it take the "today" (when upload it) date. simple.

[devonkinghorn]

I think it could be improved.

As an example, one photo was taken June 2012. It is saved to the folder 2012/06. In media it should show up in June 2012 and not dec 2023.

Somewhere the metadata exists so Nextcloud saves it to the right year/month.

[NecatiMeral]

Is there any update regarding this?

Just installed the latest nextcloud server and iOS app. Experiencing the same issue while uploading the camera roll.
