agendav's Issues

More complex recurrence rules generation

RRULE parsing and generation is really simple at this moment

Error on colorchange of shared calendar

Changing the color of a shared calendar gives an "Interface Error". The log tells:

ERROR - 2012-08-09 15:10:25 --> sany@**** Call to modify_calendar() with shared calendar, but no sid was found [calendar/modify]

Broken eventlist UI

The Event-list UI looks broken since one of the last commits. The Browser is Google Chrome Version 21.0.1180.79 on Debian Testing.

Support for muliple calendar subscriptions

AgenDAV currently allows a user to subscribe to only one calendar (url/login/password).

It would be a great enhancement to provide support for subscribing to multiple calendars.
Access control could be delegated to the caldav servers.
The biggest issue I see is providing a means for decide which calendar a given event is written to.

Thanks again for a great looking web interface.

Deleting a calendar produces an error

When I delete a calendar from AgenDAV, I get this error:

Error deleting calendar

Unknown error, HTTP code=200

Obviously, an HTTP 200 is not an error -- the calendar is deleted properly, despite the "error." I'm using HEAD with radicale.

Table 'prefs' doesn't exist

Hm looks like the schema for table 'prefs' is missing - can you please provide it?

Table 'prefs' doesn't exist
Filename: /agendav/web/application/models/userpref.php

Line Number: 35

Caldav right for create collection

Hello,
I have an user created in caldav, with only read permission, but when i log in with this user into agendav,
i can create and save new calendar, i don't understand why ?
Bug into agendav or webcal ?

Google Calendar access

Hi,

how can I access my google calendars. I have tried
https://www.google.com/calendar/dav/%u/user/
but I always get a login error.

Best regards
Tobi

Database updates should be automated

No more sql/changes* files, use CodeIgniter Migration feature

Implement some caching

Some caching could be added to improve performance. Use etags and ctags for this.

Display of external vcalendar sources

It might be helpfull if you can display the contents of an external vcal url (like a conference agenda) in the calendar.

Current develop branch does not work with Davical

The actual develop branch (1.2.1-312-g0607ffa) fails to work with a Davical installation. It tells that auth was incorrect.

It seems that the initial option request with DoOptionsRequestAndGetDAVHeader returns an empty response.

The status code from davical is 200 and the release adobo-agendav-1.2.4-0-g3b99ccd works.

Login via http_authorization

The ability to auto login to AgenDAV through a single sign-on to another service would be a great feature

Invitations

Add support for event invitations

Load Delegated Calendars

Please allow the loading of additional calendars for which the user has been delegated access to

Day Numbers clickable

A great feature would be:

when the user clicks the day number in week or month view, that day is shown in day mode.

Agendav misses this feature and should have it soon.

Localization support

Currently AgenDAV is only available in Spanish. Code and log messages is written in English, but UI isn't available on other languages right now.

CalDAV groups support

Self explanatory

[wish] allow 'multiweek' view

I would like to see a multiweek view in agendav, similar to the one that can be found in lightning: four rows/weeks are shown with the current week in the top row.

thanks a lot for agendav!

cheers,
stefan

Short events get displayed wrong

Events which last 30 minutes are too small to contain all the text in agenda view. They should be shortened to make them usable.

Regression in Timepicker dropdown

Since commit 454e71f the timepickers are broken. Details can be found at the comment under
454e71f#commitcomment-1705594

Non-blocking synchronize

Update: whittling this down to a single issue, since fetching events in the background will happen when caching does.

Blocking out the whole calendar interface while fetching events is quite jarring from a user experience perspective, particularly over a slower connection. Would putting the "loading" dialog somewhere less obtrusive and simply restarting it if the user made another selection necessitating a refresh (e.g. clicked the "next month" button)? Also, it seems like users will need to access the next couple of months commonly enough that it might be worth fetching them when the interface is first loaded -- would this affect performance very much?

Show/hide calendars

User should be able to show or hide certain calendar events

CodeIgniter CSRF should be handled another way

Currently every request to AgenDAV is done by JS using one of the following two ways:

1. 'on-the-fly' form, generated just to have a CSRF token. Actions that use this method: resize, drag, delete...
2. A 'real' form, generated by server and returned to JS via AJAX

JS should be able to generate its own forms, and get CSRF token from browser cookies, for example. This can be achieved by using a framework like Backbone.js.

Translate message issue.

Hi Jorge

When you clic on the "shared" tab of your agenda, and if it's not shared, this message is not referenced in traduction.

"This calendar is not being shared with anyone".

Can you add this in Transifex ? ;)

Regards,

User preferences

Add the following parameters to the Preferences page:

• Time zone
• Language
• Time/date formats
• Preferred first day of week

Fix session refresh

Session refresh is not being called

Use multiple CalDAV servers

I have calendars on multiple CalDAV servers. I believe AgenDAV currently only allows me to connect to a single CalDAV server at a time. It would be nice if I could use it as a client for all of my calendars, wherever they are located. This would involve moving the CalDAV server configuration out of the config files and into the user interface, so that the user could add remove CalDAV servers.

Import/export calendars feature

Give users the ability to import ics files into AgenDAV, and export calendar files to an ics file.

Fuzzy buttons in event editing

event editing widget's buttons appear strangely decorated and hard to
read using chrome.

Blank page

Hello,

I try to install AgenDAV on my server, but bug, blank page : http://leo-serre.legtux.org/Agenda/web/public/
Like you can see on configtest, all is OK : http://leo-serre.legtux.org/Agenda/web/public/configtest.php

What can I do to know what is the error ?

Thanks

Léo

PS: Bad english because french

Alarms and reminders

Implement VALARM support:

• ACTION: DISPLAY should be handled by AgenDAV
• ACTION: EMAIL should be handled outside AgenDAV (direct DAViCal query?)

DateTime::createFromFormat() not availble in PHP 5.2

The code in web/application/libraries/Dates.php fails on php 5.2 due to calls to DateTime::createFromFormat().

Perhaps someone can come up with an alternative implementation based on strptime()?

Updated german translations

Hello, can you please update the german translations? I've a patch for you at https://gist.github.com/2765611

More sharing options

AgenDAV currently supports read+write calendar sharing. It would be interesting to implement per-share privileges

Changing calendar color results in HTTP 500

When you save a calendar's settings after changing the calendar's color, this error is displayed:

Invalid value

Unknown error, HTTP code=500

...and the dialog box does not disappear. However, the color change is saved.

Problem with duration of all-day events

Let say that we want to add event that lasts 3 days. We have two ways:

• Select 3 days long period of time on the calendar, dialog box will pop out.
• Fill in all details, choose ‘All day’ option and hit save.
  Or
• Click on start date.
• Fill in all details, select ‘All day’ and choose end date.
• Hit save.

These two scenarios gave us the same result – 3 days period of time is displayed as 2 days and saved in davical’s database as 2 days event. This problem not occurs when we add long events but with giving particular start and end hours.
Besides that if someone want to add all-day even that lasts 1 day, in ‘New event’ dialog start and end date differs (end date = start date + 1), they shouldn’t be the same? Possibility to add an all-day event with the same start and end dates is much more intuitive, and is used in other well-known calendars such as Google or Lightening.

Copy events

It would be great to have the ability to copy an event from a calendar to another, when a user has access to more than one calendar

Vertical space for the calendar view

It would be nice to move the bottom of the page (AgenDAV's logo) to gain vertical space for the calendar.

Maybe you can put the logo just below the list of calendars.

Forbid writes on calendar when calendar is read-only (admin profile)

Hi,

This is not a critical issue. Sorry for my poor EN!

• Last commit of GIT installed
• My user is declared as administrator in davical server.
• My user have access to different shared calendar (read only).

I can create events (and i shouldn't) on all the read only shared calendars because I can choose the read only calendar on "create an event" into the calendars list.
For the deletion of events, i can't (no delete button).

Davical allow full writes for administrators, so It's normal that the davical server don't cry when you create/delete event on any calendars of the server.

I think that the best way might be to rebuild the calendar list of "create an event" depending of the access writes of each shared calendars.

What do you think?

Regards,

Adrien

Latest Git version doesn't work with calendarserver

When using current Git HEAD with calendarserver (2.4.dfsg-6 from Debian Squeeze), AgenDAV fails to load calendar contents, with error message:

"Interface error
Error loading events from calendar oliver:calendar"

It shows the calendar (displayname and color) but no events; so basic communication works.

Also, it works fine with version 1.2.3.

Log from AgenDAV shows this:
ERROR - 2011-12-15 00:15:44 --> Invalid CalDAV server
ERROR - 2011-12-15 00:15:44 --> [email protected] Possible invalid CalDAV server [caldav2json/events]

Log from calendarserver shows this:
192.168.0.43 - oliver [15/Dec/2011:00:15:39 +0200] "OPTIONS /calendars/users/oliver/ HTTP/1.1" 200 0 "-" "DAViCalClient" i=8008 t=69.8 or=1
192.168.0.43 - oliver [15/Dec/2011:00:15:43 +0200] "PROPFIND /calendars/users/oliver/ HTTP/1.1" 207 3343 "-" "DAViCalClient" i=8008 t=86.2 or=1
192.168.0.43 - - [15/Dec/2011:00:15:44 +0200] "OPTIONS /calendars/users/oliver/calendar HTTP/1.1" 301 175 "-" "DAViCalClient" i=8008 t=35.9 or=1

I would guess the HTTP 301 redirect is a problem. Maybe it happens due to commit 803b5e6 which wasn't present in version 1.2.3. Also, that version showed similar problems with HTTP 301 in other places (PROPPATCH).

500 on calendar/modify

The latest develop branch returns a 500 internal server error from the POST request modifying a calendar. This even happens on a fresh database and no changes in the calendar dialog (simply click "save")

Automatic Refresh of Calendars

It would be nice if there is an automatic refresh of the calendars instead of hitting the button every time.

Automatic refresh can be on opening a connection to SabreDAV in the background and listening for new events for example. Aor just refreshing the page after x sconds/minutes.

Tasks management

Implement VTODO elements management

Take advantage of "ymd" label in table view.

Hi Jorge, hi team.

Well done for the new feature!

In the "Next month" area in table view (fr_FR) i have:

Avr 10, 2012 Event1
Avr 13, 2012 15:00 Event2
Avr 16, 2012 - Avr 19, 2012 Event3

Is there a way to implemant "ymd" option of config.php into table view?

For exemple if we have:

$config'[default_date_format'] = 'dmy';

The result should be (fr_FR)
10 Avr, 2012 Event1
13 Avr, 2012 15:00 Event2
16 Avr, 2012 - 19 Avr, 2012 Event3

Adrien

Zimbra support patch

I just setup AgenDAV in front of a Zimbra (7) server. Works well now, but I had to manually patch

libs/davical/inc/caldav-client-v2.php : Zimbra sends "Allow: ..." answer on multiple lines, preg_replaces only gave the last line in $options_header in DoOptionsRequest(). AgenDAV could not get all properties and gave authentication error.

BTW, Zimbra Caldav urls are (add them to the doc) :

$config['caldav_principal_url'] = 'https://zimbra.server/dav/%u/';
$config['caldav_calendar_url'] = 'https://zimbra.server/dav/%s/';

patch :

$options = array_flip( preg_split( '/[, ]+/', $options_header ));
return $options;
--- 351,360 ----

! }
$options = array_flip( preg_split( '/[, ]+/', $options_header ));
return $options;

Works well now. Sorry for lack of proper GITting I am in a hurry ....

Delete one instance of a repeated event (occurences).

Hi team.

When you add a repeated event, for exemple:

• Repetition: each week
• To 31/12/2012

After that, you have no possibility to delete only one event of this repeated event.

You can just delete all instances...

Is-there a solution to permit the deletion of only one occurence, as ical or lightning do?

In lightning you have the choice:

• Edit just this occurrence
• Edit all occurences

Regards,

Recurrence exceptions

Give users the ability to define recurrence exceptions or remove single recurrence instances

Change translation system

Use gettext and an online service (e.g. https://www.transifex.net) to make easy translating AgenDAV.

Add a different link for the logo on login page

Hi Jorge, Hi team.

All is in the title!

It could be cool to have a different pass to chose a different logo on the login page.

For exemple, I had hard-coded to change the logo size, it was very small! (but in a bad way.... ;) ).

Regards,

Adrien

Exemple in config.php:

/*
Logo
--------------------------------------------------------------------------

|
| Filename from public/img
|
*/
$config['logo'] = 'agendav.png';
| Filename from public/img. Only for login page.
| $config['logo'] is chosen by default.
$config['login_logo'] = 'agendav_big.png';
