Symlinks on the photos directory break Pigallery2

[tkedwards]

If you have any symlinks in the photos directory (Images folder) you get the following error in the UI:

Unknown indexing error for: ./
"[object Object]" 

Errors from the logs (from docker logs, I'm using the docker image):

Hi,

Thank you for your report.
Can you give me same more details:
Are you setting your root images folder as a symlink so like: -v <path to a symlink>:/pigallery2-release/demo/images ? Or you have a regular root images folder that contains several symlinks?
Also can you double check if the app has read right on the folder/symlink?

Hi Patrik,

Are you setting your root images folder as a symlink so like: -v :/pigallery2-release/demo/images ? Or you have a regular root images folder that contains several symlinks?

The root images folder path is a symlink. The problem only happens when I have symlinks inside the root images folder, once I moved the symlinks elsewhere the problem went away

Also can you double check if the app has read right on the folder/symlink?

The symlinks had 777 permissions, and the app is running in Docker so is effectively root AFAICT

BTW thanks for developing Pigallery2! I searched for ages to find a photo gallery that would work with my existing folders (since I manage the photos using Digikam) and that actually has basic features like video playback and display of comments. Piwigo and Lychee were no good, Nextcloud Gallery is pretty hopeless. Yours is the only one that does things right!

Hi,

Thank you. I'll look into it and get back to you in the next few days (worst case weeks).

Thank you! I'm glad that you like it :)
Yes, this project is helpful for those who manage their photos separately.
I'm doing hobby photography with lightroom post production and I try to put a lot of effort in organizing the photos (like: geo tagging, keywording, adding faces). This app suits the best for those who does the same :)

Hi,

I've checked and the problem seems to be with docker.
I've also tested it on raspbian with direct install (so no docker) and I could use both folder and file symlinks within the images folder.

Here you can read more about the docker's symlink issue:
https://stackoverflow.com/questions/38485607/mount-host-directory-with-a-symbolic-link-inside-in-docker-container

You can try changing the way, you make your image folder accessible by docker, but I cannot really give any guidance with that. Maybe look around here: https://docs.docker.com/storage/

Thanks, it's annoying Docker can't handle that well. In that case not a pigallery2 issue so I'll close this.

I ended up removing the symlinks from inside the 'photos' directory because they weren't really needed.

In the mean time I figured that the issue with the symlinks are probably that the path to the folder might point outside of the mounted volume. (or the path to the linked folder is different within the docker) You can try the following: 1) mounting your whole host or a larger set of your host like `-v /:/hostroot` (not sure if you can mount the whole `/` 2) changing the path to the image folder settings within the app. I haven't tested it. Best, Patrik

Thanks, that's probably it since the symlinks were to a folder outside of the 'photos' folder

Hey, I just found this issue.
I am having problems getting PiGallery2 working with symlinks.

My idea was to create a folder in the Nextcloud folder, where I can sync my photos from my iPhone to.
Then I would like to display them in PiGallery2, that's why I linked the folder from the Nextcloud folder to the folder where PiGallery displays the pictures from with ln -s.

When I want to access the subfolder, where the images are in, I get this error:

My version is latest_2.0.11.
