#531 Since IOS 7 the CalDav seem to loop fetching data infinitely

Caldav (161)

Since IOS 7 the CalDav seem to loop fetching data infinitely
My Debug logs are going crazy over the same items all the time and the Cellular Traffic as well.
It looks like every minutes that pass re-trigger the download of the calendar item..

    I think since IOS 7 it tries to fetch Tasks... and each of theses tasks query are looping.. from what i see in the log.

  • Mickael Guessant

    Nothing obviously wrong in your log file, it's polling the calendar every 15 minutes

    Yeah calandar items are fine but it seems to loop over TASK items.... "Reminders".

    HI Admin, the problem with IOS7 is not resolve, it doesnt loop anymore, in fact you see the events appearing on the phone and disapearing at the same time, i created a case ticket at apple, however they say they see the issue comming form the DavMail services.. i can assist you working over the problem and test if required.

    I also speak French if that helps in anyway.

    I have the same problem (events show for a moment then disappear). I have an iOS 6 device on the same server that works properly. I have emailed logs for both iOS 6 and iOS 7.

    Yep been having this same issue since upgrading to IOS7 I believe the issue to be in IOS7 as IOS6 still works and I seen a reply somewhere where someone said ipad IOS& is working not verified by me though.

    I have verified pre IOS7 i am still working on another iphone, my iphone with IOS7 has the rinse and repeat calendar gets loaded then it disappears completely. This happens once or twice then it appears to stop trying.

    I posted on the apple forums as well.

    Confirmed, there is an issue with User-agent check.
    Fixed in subversion, still untested though (I do not have an iPhone)

      I will try to grab a snapshot tonight and test it.

        Sorry, had a problem with the encoding check and had to solve that to get it to compile. Your patch has fixed the problem (at least iOS7 works I can't check backwards compatibility).

  • Mickael Guessant

    Great, thanks for your feedback

    Hey would someone want to compile it for me for windows and shoot me the .exe ?

    I was able to download and compile with the Trunk, and verified this is working. The calendar on my iPhone stays.

    I tried build 2187 of DavMail and it is better, but no cigar. The calendar is not disappearing from the list of calendars anymore, but I don't see my appointments. It's interesting to note that the Calendar app in OS X Maverick is working fine. Also, still have the MIME mail issue on IOS 7 with build 2187. I can't read MIME encoded messages. Again, Mail app on OS X Maverick works fine. Ping me if you need to test, it will be my pleasure. Thank you very much for your hard work and keep it up!

    Can you please provide a log file of the caldav sync at ?

    I am using Trunk 2185 without issue.
