Cannot WebDAV upload file into shared folder as recipient with enc enabled

[PVince81]

Steps to reproduce

1. Enable encryption (note: I haven't tried without it yet)
2. Log out and log in again as admin ("root")
3. Create a user "user1"
4. Login as "user1"
5. Create folder "folder"
6. Share "folder" with "root"
7. With a WebDAV client (cadaver), login as "root"
8. PUT a file into "folder"

Expected result

Upload works.

Actual result

Versions

ownCloud 8.1 pre-alpha git master (8e8acad)

@schiesbn @icewind1991 I suspect it might be related to the "reuse file id" PR.

Going to bisect this now.

Edit: added missing "share" step

[PVince81]

Only happens for newly created files (overwriting existing works)

This is the bad commit: 9df18ff, part of #10993

@icewind1991 please have a look. Thanks

[PVince81]

Please also add a unit test to protect against such regressions.

cant reproduce this...

Also I cant see any way that commit causes such a problem...

[PVince81]

This was with mariadb-10.0.14-2.3.x86_64 in case that makes a difference.
Did you follow the exact same steps ?

[PVince81]

Still happening on master (7325414)

I'll try with another DB to rule out mariadb.

[PVince81]

Ah, it works with sqlite!

[PVince81]

Cannot reproduce on master (a672e9d) with the new encryption. Closing.
