Can't refresh calendar

[petobens]

I read in issue #44 that:

you want to refresh, remove ~/.cache/calendar.vim/timestamp/ before starting up the app

However if I add an event to my calendar via the web interface, then remove ~/.cache/calendar.vim/timestamp/ and finally open the app, that event doesn't show up. The only way I found to make the new event show up is to create a second new event but this time from within Vim. By creating an event from within Vim, the vim calendar becomes synchronized with the web calendar.

I think that you have to restart Vim.

[petobens]

I restarted Vim and the behavior is same: in order to refresh the calendar I need create a new event within Vim. On the other hand the Tasks do get refreshed when I delete the ../timestamp directory. So the problem is with the calendar events. Can you please check it and fix it? Thanks

[itchyny]

Cannot reproduce and I cannot fix. Please read the log with opening the calendar by :Calendar -debug. The downloaded log is saved in ~/.cache/calendar.vim/download/.

[petobens]

Running with :Calendar -debug and looking into~/.cache/calendar.vim/download I get a lot files that look like: google_calendar_download_201409092028580007. What information is useful to you? Where should I find it? For instance, the first the files (if ordered by date modified) reads:

HTTP/1.1 404 Not Found

Not Found

And the last one of those files:

    "message": "The requested data is not available."
}
],
"code": 403,
"message": "The requested data is not available."
}
}

One strange thing I notice is that it says Date: Tue, 09 Sep 2014 23:29:05 GMT and actually the time when I execute the :Calendar -debug command was Tue, 09 Sep 2014 20:29:05 GMT (three hours earlier than what it shows).

Thanks for the help and patience. :)

Please remove the ~/.cache/calendar.vim/ directory and reauthorize the app to the Google Calendar.

[petobens]

I removed the ~/.cache/calendar.vim/ directory and reauthorized the app to the Google Calendar. The events were succesfully loaded. After doing that I created a new event in the Google calendar web app, then deleted ~/.cache/calendar.vim/timestamp/ and finally opened vim and the calendar app, and that event doesn't show up. Once again the only way to make it appear is by creating a new event from within Vim. Task synchronization works just fine. For the calendar the log reads:

    HTTP/1.1 403 Forbidden

    }

[itchyny]

Does this problem still happen? I've looked through the log on my environment and I've never get insufficientRightsForApiAccess error. I still do not find the clue to fix this error.

[petobens]

I''ll do same testing and revert ASAP. Thanks

Here's a diff which generates a more detailed log. The output file is ~/calendar-vim-log.txt. I want you to see the difference of the logs of successful case and failure case.

Sorry for taking such a long time to reply. So I added the lines in your previous comment and got the log result of removing the ~/.cache/calendar.vim/ directory and reauthorizing the app to the Google Calendar so the events are succesfully loaded. Do you want me to copy the whole file here?

Even in the success case I get a line that reads like:

['HTTP/1.1 403 Forbidden', 'Vary: Origin', 'Vary: Referer', 'Vary: X-Origin', 'Content-Type: application/json; charset=UTF-8', 'Date: Thu, 09 Oct 2014 23:02:35 GMT', 'Expires: Thu, 09 Oct 2014 23:02:35 GMT', 'Cache-Control: private, max-age=0', 'X-Content-Type-Options: nosniff', 'X-Frame-Options: SAMEORIGIN', 'X-XSS-Protection: 1; mode=block', 'Server: GSE', 'Alternate-Protocol: 443:quic,p=0.01', 'Transfer-Encoding: chunked', '', '{', ' "error": {', '  "errors": [', '   {', '    "domain": "calendar",', '    "reason": "insufficientRightsForApiAccess",', '    "message": "The requested data is not available."', '   }', '  ],', '  "code": 403,', '  "message": "The requested data is not available."', ' }', '}']

or like this:

['HTTP/1.1 403 Forbidden', 'Vary: Origin', 'Vary: Referer', 'Vary: X-Origin', 'Content-Type: application/json; charset=UTF-8', 'Date: Thu, 09 Oct 2014 23:02:36 GMT', 'Expires: Thu, 09 Oct 2014 23:02:36 GMT', 'Cache-Control: private, max-age=0', 'X-Content-Type-Options: nosniff', 'X-Frame-Options: SAMEORIGIN', 'X-XSS-Protection: 1; mode=block', 'Server: GSE', 'Alternate-Protocol: 443:quic,p=0.01', 'Transfer-Encoding: chunked', '', '{', ' "error": {', '  "errors": [', '   {', '    "domain": "calendar",', '    "reason": "insufficientRightsForApiAccess",', '    "message": "The requested data is not available."', '   }', '  ],', '  "code": 403,', '  "message": "The requested data is not available."', ' }', '}']

Please mail the log to me itchyny.itchyny@gmail.com Edit the place which contains some private events.

[petobens]

This is awesome!!! Thank you so much :) Brilliant app!!!

[itchyny]

I'm very very sorry that it took a long time to investigate the reason. But I could reproduced this problem yesterday and I could fix the issue.

[petobens]

I'm very sorry for not providing further assistance! But really I had no idea what was going on. Thank you once again.

[nikisix]

YOU GUYS ROCK!!

For others coming to this thread for the same problem, the solution that ended up fixing my problem was to:

1. Update the Calendar.vim plugin via a PluginUpdate command in vim
2. rm -r ~/.cache/calendar.vim
3. Start Calendar and it will ask you to re-authenticate with google (just paste the code into vim)

Cheers

@ntomasino thanks for a catch :100:
