Cloud not found

[hepaly]

Hi guys, I have an intresting bug. I can not open the shared link (which has shared by another user in my cloud) if I logged in OC. -> Cloud not found
If I logoff, then I can open it.

(OC 4.5.9 is working well!)

I can reproduce the bug. It seems like setupFS()[1] doesn't work if a file system is already set up which is the case if the user is already logged in.

I tried to replace "OC_Util::setupFS($fileOwner);" with "OC\Files\Filesystem::initMountPoints($fileOwner);" but this also doesn't solve the problem. @icewind1991 any idea what's the best solution here?

I'm currently having the exact same issue, the public link returns a 200 if the user is logged out, while if they're logged in; it will return a 404.

Expected behaviour

Users should be able to view the shared public links without having to logout.

Actual behaviour

Generates an error instead, "Cloud not found".

Steps to reproduce

1. Share public link
2. Open shared link while being logged in -> unable to view
3. Logout
4. Open shared link after logging out -> can view the link

Not sure how I would debug it further, but https://github.com/owncloud/core/blob/master/apps/files_sharing/public.php#L50, the $path variable is empty, however the file_source links to the correct ID.

I can't reproduce with stable5. This seems to be temperamental and people are saying different things.

@Contex are you saying the same user or a different user? The original report says a different user is logged in trying to access the link.

@schiesbn I think it's up to you, because I've tried every case over and over.

[MTGap]

There's also this weird one: #3097 Last comment says it happens in 5.0.6 as well.

Another: #3014

I can't reproduce any of them.

[Contex]

@MTGap
User A is logged in and shares via link.
User B is another user that is logged in.
User C is a visitor, which is not logged in.

User A shares the link with User B, User B is unable to view the shared link and gets a "Cloud not found".
User A shares the link with User C, User C is able to view the shared link.
User B logs out and opens the shared link again and is now able to view the shared link.

I was debugging it a bit yesterday but didn't have that much time, I'll try again later today.

[gerardstanczak]

I can confirm this happens in 5.0.6, just like user @Contex above mentioned
PHP 5.4.15, CentOS, MySQL backend,

@MTGap when i create an Link, and open this link as already logged in, i can see the Files. But when i log out. i became the Error "Cloud not found"

[MTGap]

Everyone is saying something different...

[Contex]

@MTGap I can link you to my ownCloud installation and give you ssh if needed, if you wish to debug.

[MTGap]

I can only reproduce the case with another user logged in on the demo. Not on my installs.

Here is a short demo for reproduce:

[hepaly]

sorry :)

[Happyfeet01]

Okay i have try to reproduce.
I have shared an JPG Image https://owncloud.speicherwoelkchen.de/public.php?service=files&t=4e52339a9c2a482935c95ef605f25ef1
and an Folder https://owncloud.speicherwoelkchen.de/public.php?service=files&t=d63682c1cf464846210fce367c5a4a38

its not possible to open the Image file (Cloud not Found), but it is possible to access the shared folder. with an Picture inside.

When an file is inside of an Folder and you share only one file inside this folder, its possible to access this file.
https://owncloud.speicherwoelkchen.de/public.php?service=files&t=86ec3ae3620120e31d7076888e296575

the knowledge of this error:

sharing of folders and files inside of folders works, but sharing files at the root directory at /data/Username/files dont work.

sorry for my bad english :-) but i hope you understand what i mean......

[hepaly]

Thanks your work! I patched the:
/apps/files_sharing/public.php
cron.php
lib/files/filesystem.php
lib/files/cache/updater.php
files in OC5.0.6, and working well! :)

[redhandpl]

@hepaly What did you changed in:
lib/files/filesystem.php
lib/files/cache/updater.php

[hepaly]

@redhandpl I'm using the stable OC5, and I patched those files by this link:
#3457
