regression in DAVx5 2.6.1, 403 when PUTting calendar entry

infinity0

I recently upgraded to 2.6.1-ose and now calendar inserts (to apple calendarserver 9.2, on Debian) are no longer working with error code 403 (Client Forbidden). The server access logs show:

127.0.0.1 - infinity0 [XXX] "PUT /calendars/__uids__/XXX/calendar/XXX.ics HTTP/1.1" 403 335 "-" "DAVx5/2.6.1-ose (2019/11/23; dav4jvm; okhttp/3.12.6) Android/9" i=1 or=1 t=82.0 cl=693 err=valid-calendar-data

Previously with 2.6 it was all fine:

127.0.0.1 - infinity0 [XXX] "PUT /calendars/__uids__/XXX/calendar/XXX.ics HTTP/1.1" 201 0 "-" "DAVx5/2.6-ose (2019/10/28; dav4jvm; okhttp/3.12.6) Android/9" i=3 or=1 t=80.7 cl=689

Hi,

Please provide steps to reproduce, Web server and CalDAV/CardDAV server logs taken while the problem occurs, DAVx⁵ debug info (DAVx⁵ / Settings / Debug info) and verbose DAVx⁵ logs etc as described in [READ BEFORE POSTING] What’s required to diagnose a problem.

Hi, steps to reproduce for me is (1) install 2.6.1 and (2) insert a calendar entry and try to synchronise, against an apple calendarserver. I don’t think I have any non-default settings, at least for caldav. The account is a “login with URL and username” type of account.

I have already downgraded back to 2.6 to get my account working again, and would prefer not to have to re-upgrade and re-downgrade because it takes a while to set up the accounts. (On android a direct downgrade is not possible, you have to uninstall and reinstall.)

The server log error err=valid-calendar-data suggests that DAVx5 2.6.1 is sending some data that’s different than in version 2.6, and it is this data that apple calendarserver does not like. I guess there have not been that many major changes from 2.6 to 2.6.1 in this area, so hopefully the bug can already be deduced without me having to reinstall 2.6.1 and provide more detailed error logs?

Without logs, this is all a guessing game. I’ll try to reproduce the scenario, but it will be much work (dig out the Calendarserver VM, check the version, set up DAVx5, try it out…) and with logs I could probably just see the reason without any additional work.

Do you use email reminders for events? Which event did you try to upload?

infinity0

I don’t use email reminders, and the event details were pretty ordinary, with no special Unicode characters or anything like that.

I will try to find some time to produce some more detailed logs in the next few days.

rfc2822

Thanks. I have just tried to test with calendarserver, but it doesn’t start anymore and instead I get this problem (after having fixed another one).

Or can you maybe provide a temporary (Internet-accessible) test account?

infinity0

Which problem do you mean specifically? That thread is long and has a lot of separate issues. If you are talking about “calendarserver_upgrade is not working”, the fix is in message #50.

Alternatively you could try reinstalling a whole new calendarserver instead of upgrading - that thread is also nearly 4 years old.

rfc2822

@infinity0 Yes, I just got it running…

rfc2822

Can reproduce the problem:

<error xmlns='DAV:'>
  <valid-calendar-data xmlns='urn:ietf:params:xml:ns:caldav'/>
  <error-description xmlns='http://twistedmatrix.com/xml_namespace/dav/'><![CDATA[Calendar data had unfixable problems:
  [VEVENT] Missing or too many required property: DTSTAMP]]></error-description>
</error>

Seems that 2.6.1 doesn’t send a DTSTAMP anymore for whatever reason.

So thanks for the report, no additional information needed.

Bug-Ninja

I am experiencing the same problem, regardless of the calendar app I use. It seems DTSTAMP is missing when trying to update/add an appointment to the server. Server gives no problems on other devices (laptop with thunderbird and tbsync).
