Checksum is only set every 2nd WebDAV upload

Server
1

I might be missing something, but this seems weird to me. If I upload a file via WebDav several times, the checksum field in the MariaDB is only set every 2nd upload. If I include the http “OC-Checksum:” header for the upload, the behaviour remains the same. After I refresh my localhost-browser-view, the db checksum is also set.

Steps to reproduce


  1. Upload a file via WebDav/cURL
curl -u admin:admin "http://localhost:8080/remote.php/dav/files/admin/test.txt" -T "test.txt"

  1. Check the MariaDB entry

MySQL commands

Login

mysql -u owncloud -p
owncloud

Select owncloud database

use owncloud;

Show checksum entry of “files/test.txt” from filecache table.

SELECT path, checksum FROM oc_filecache WHERE path="files/test.txt";
Or WebDav PROPFIND

Request:

curl -u admin:admin "http://localhost:8080/remote.php/dav/files/admin/test.txt" -X PROPFIND --data-binary @"find.txt"

with find.txt:

<?xml version="1.0" encoding="utf-8" ?>
<a:propfind xmlns:a="DAV:" xmlns:oc="http://owncloud.org/ns">
    <a:prop>
        <oc:checksums/>
    </a:prop>
</a:propfind>

  1. Repeat the upload
curl -u admin:admin "http://localhost:8080/remote.php/dav/files/admin/test.txt" -T "test.txt"

  1. Check the MariaDB entry again
