Hey folks,
I'm working on some very very very preliminary integration with Stikkit.
I'm no programmer but I can hack my way around a shell script...
Stikkit's API allows me to pull my calendar items in .ics format, which I've done using curl. I was hoping to then use curl again to post those items into zimbra.

I did some searching for the command and found:

Code:

 curl -u user--data-binary ~/stikkits.ics http://server/zimbra/home/user/calendar?fmt=ics

However, it seems to fail on the first line of my stikkits.ics file (posed below)

I've also tried just using the built in sync feature to point a new calendar to Stikkit's feed (which I believe is an atom by default). Thats not an idea solution, but it was a way to troubleshoot. I didn't get any errors, but I didn't get any appointments either.

My goal is to eventually write a zimlet that lets me do some 2 way syncing b/t the two, but right now I have to do it with baby steps...

here is the result of my stikkit API call that returns a .ics file

Code:

Like I said, I'm no programmer, but if I need to modify a tag or field I think I can manage that....

thanks in advance!

Just to make sure, you actually have spaces between the user and the --data-binary, right?

If so, what error is being returned?

Good catch, yes I do have spaces there...when I replaced my actual username with the word 'user' I must have lost the space...

Looks like a syntax error parsing your .ics file. I'm not an .ics wizard, so why not just file this in bugzilla and attach your .ics file as an attachment to the new bug? We'll let you know if the .ics file is completely malformed or if there's a parser bug on our side...

I'm happy to do that. I'm no stranger to software development in my profession but I am when it comes to open source and community efforts like this. I wasn't sure if 'just anyone' could log issues in bugzilla and what kinds of things constitute valid issues.

I'll log it today, thanks.

Note that use you can also use zmprov/zmmailbox to post to a rest url:

Code:

zmprov sm user1 pru /calendar test.ics

The sm (selectMailbox) command in zmprov will select a mailbox and switch you into zmmailbox command mode.

The pru (postRestUrl) command (part of zmmailbox) will post a file to a particular URL that is relative to the account.

I posted the sample you provided (after adding a END:VCALENDAR), and the server log (/opt/zimbra/log/mailbox.log) has:

Code:

com.zimbra.common.service.ServiceException: invalid request: Could not parse DURATION string: 20070827T234500

Your sample had that value in TRIGGER:

Code:

TRIGGER:20070827T234500

In taking a quick look at the iCalendar RFC, TRIGGER is supposed to be a duration relative to the appointment start time. If you want it to be a specific time, you need to use a different format:

Code:

     TRIGGER;VALUE=DATE-TIME:19970317T133000Z

I'm no iCalendar expert though, I just did a quick search through the RFC (and I'm in the middle of implementing calendar for the basic html client).
