The API currently overrides the supplied permissions with "read only" when a file is shared via link. It allows to update the permissions later, however.

Fixes #32611

It would be still nice to preserve the default of read only permissions for the share links, maybe by moving that to the first condition in https://github.com/nextcloud/server/pull/35213/files#diff-dbbe017dd357504abc442a6f1d0305166520ebf80353f42814b3f879a3e241bcR481

What do you think?

+1 for keeping defaults - although it seems wrong to willfully ignore the setting. Changed nonetheless.

The 3 failing tests all explicitly sets PERMISSION_ALL but expects the share to only have read permissions. Fixed two of them to expect PERMISSION_ALL and one to not set permissions at all and expect READ|SHARE.

The API currently overrides the supplied permissions with "read only"
when a file is shared via link. It allows to update the permissions
later, however.

This keeps the default to "read only" but honors the permissions
supplied by API call if any.

The amount of tests that cement the old behavior is staggering. After fixing 4 unit tests, now acceptance-app-files-sharing is failing in a way I don't quite understand yet. Apparently a readonly user (!) share can now be re-shared readwrite. I don't yet see any connection to my patch, but it's close enough to probably be caused by it.

The acceptance tests can be randomly failing from time to time.

I've restarted the drone job to double check

Indeed, now the a acceptance-app-files-sharing tests all succeed (but acceptance-app-theming still fails, though probably unrelatedly, and samba now failed, which it previously didn't).

Yes, seems all unrelated.

Looks good.

@skjnldsv you added a TODO about it in the front-end, but I don't understand what it is referring too. Should we do something there too ? As this PR seems to "fix the createShare method".

// we do not allow setting the publicUpload
// before the share creation.
// Todo: We also need to fix the createShare method in
// lib/Controller/ShareAPIController.php to allow file drop
// (currently not supported on create, only update)

Backend permissions are always tricky for sharing.
I haven't looked deep into that PR, but we need to make sure the front is compliant to this PR. I don't remember adding any check, but this is usually the thing to adjust and check

Without having looked into the frontend code, I don't see how this PR could pose a problem. It preserves the default, and the frontend always first creates the share link without specifying permissions, and only allows setting permissions later on.
