Scan fails on symlinked zip file: not a valid zip file

[evandeaubl]

Describe the bug
When I symlink a zip file into one of my Stash library directories and do a scan, it is not integrated into the library as a gallery. When you look at the logs, you see a "not a valid zip file" error logged.

Copying the same zip file into the Stash library at the same location and scanning works correctly.

To Reproduce
Steps to reproduce the behavior:

1. Symlink a zip file into one of the active library directories enabled for images
2. Go to Setttings->Tasks, and select Scan
3. Go to Settings->Logs, and observe that zip file scan resulted in "not a valid zip file" error

Error scanning zip file "XXXXX.zip": zip: not a valid zip file

Expected behavior
Zip file integrated into Stash library as gallery

Stash Version: (from Settings -> About): 0.22.1

Desktop (please complete the following information):

• OS: macOS
• Browser: Safari
• Version: 17.0

As far as I know, symlinks are just a link to another location, if that location it's outside your library folders, I don't think stash will be able to index it. You probably should use a hard link instead, wich is more like a mirror.

Same problem on Debian with zip files in symlinks not working with Stash (get error message - not valid zip file while scanning, same file work well when not symlinkes).

Current tested/working hack to resolve this - mount directory with Samba set to resolve symlinks.

Proper fix will be much appreciated!

I've managed to reproduce this. It's a bit of an involved fix, so I likely won't fit it into a 0.26.x bugfix.
