Nextclouds dav clients tries to read {DAV:}getlastmodified but it's missing.

http://webdav.org/specs/rfc4918.html#METHOD_PROPFIND https://lists.w3.org/Archives/Public/w3c-dist-auth/2003JulSep/0149.html

@rullzer @icewind1991 How do you read the rfc? I think getlastmodified property is not required for a collection but recommended?

Thanks @kesselb for the patch. Sorry for the late response, I was on a vacation.

I tried your patch today (sorry, still under 16.0.1.1) and now another line in the DAV.php is not happy:

The problem seems to be in the function stat now:

public function stat($path) {

                        $response = $this->propfind($path);

I suppose this is still valid on NC21.0.2?

This issue has been automatically marked as stale because it has not had recent activity and seems to be missing some essential information. It will be closed if no further activity occurs. Thank you for your contributions.

Confirmed valid on 22.1.1.

Maaxxs commented 2 years ago

Hi, I can confirm that this error is still happening on version 23.0.2.1.

However, I'm getting this error with a nextcloud share, which was shared with me (so similar issue but I thought I comment here first before creating a new issue).

The patch at the bottom fixes the undefined index in the stat function. I also took the changes from the patch by @kesselb. However, I changed the return value in the else clause to false if neither getetag nor getlastmodified is set. At least, I would argue that it should return false because false is returned if there is no response ($response === false), and in the exceptions, too.

In the issue description are some errors from other php files as well. This patch fixes the errors in the DAV.php file. So, I guess, it would be nice to merge this anyway, if someone could check this and if it looks good :)
