Mozilla Calendar Project Blog Its about time for some news…

Another week has gone by and another 12 bugs have been fixed in the last few days. There was nothing particularly interesting this time, just the usual bug-fixing and polishing going on.

Here’s the complete list with all the 12 bug fixes:

Thanks again to all our developers, contributors, localizers, testers, and supporters.

As mentioned in Wednesday’s status report a lot of last week’s bugfixes fix important or longstanding issues and deserve special attention. In the first part on Thursday I already described the most important fixes with regards to performance and the calendar backend. Today comes the 2nd part, where I’ll describe the more user-facing changes in the front-end in more detail. Of the four important fixes, three apply to Lightning’s new task mode, which was got quite some polish in the last few days. Now let’s get down to business:

• Bug 257428: use alarms? — preference on a per-calendar basis
  The ability to work with many different calendars is definitely a strong point of Lightning and Sunbird. In the past however, if you were subscribed to a calendar of one of your friends, working with different calendars could become rather annoying, because alarms for events in your friends calendar would also be displayed in your installation – whether you wanted to know about it or not.

  Thanks to Sebastian Schwieger this is now a thing of the past, because now you can enable/disable the display of alarms for every calendar that you are subscribing to. Thanks go also to Philipp who reviewed the patch.

• Bug 408798: Optimize Menu Structure for Task Mode
  With this patch the task mode in Lightning now offers a menu structure, which is more focussed on task-related features. Before that patch went in we were using the same menu structure in task mode and calendar mode, which is clearly bad from a UI perspective as the two modes have different characteristics. The next step in the coming weeks will be restructuring of the task mode toolbar to make it also more focussed on task-related features.
  Thanks go to Berend for the implementation, Christian for the initial design and to Mickey for the review.
• Bug 411497: Task mode should offer some sort of filtering
  The event list in Lightnings calendar mode offers the possibility to filter the list of events which should be displayed. A similar feature was lacking in task mode. As of now, you have the ability to filter the list of tasks in the left-hand sidebar in task mode. The selection of filters offers stuff like today’s tasks, overdue tasks, completed tasks, etc.

  Thanks to Mickey for his implementation and to Berend who reviewed the patch.

• Bug 411498: Task mode details pane doesn’t show enough details
  Until now the task mode was a pretty bleak place. The lower “detail pane” would only display the task title and the description text. With Mickey’s new patch (and Berend’s review) many more details like priority, start date, due date, category, state of completion, recurrence, etc. will now be shown as well, giving you a much better picture on your current tasks.

I hope you are as excited as I am. With all this new stuff the upcoming 0.8 release is going to rock. Stay tuned for more!

As mentioned in yesterday’s status report a lot of last week’s bugfixes fix important or longstanding issues and deserve special attention. This is the first part (of two) describing those important fixes in more details. So let’s get down to business:

• Bug 323011: Unifinder default option should not be ‘all events’
  When working with larger calendars our startup time was pretty horrible. One major cause of this was “Event List” (aka unifinder), which by default would display all events of all activated calendars. This can of course take some time, especially if you have a lot of larger calendars.

  What we did to fix this is look at how people use the unifinder. We noticed that most people seem to use it to look at the events of today or maybe the next few days, but not the events of two years in the past. So from now on, the unifinder will only display today’s events by default. You can of course still configure it to display other timeranges. Thanks go to Philipp for implementing this and to Daniel for his review.

• Bug 328996: guessSystemTimezone doesn’t take northern/southern hemisphere into account
  When you start Lightning or Sunbird for the first time, it tries to guess in which timezone you are working. In the past our algorithm for doing this did a poor job in some cases. While it would normally guess the time offset correctly (e.g. if you were living in central Europe, it would guess that you were in GMT+1), it did a poor job on guessing your real location. This sucks, because if you are living in Germany and Sunbird thinks that you are working in Algeria, then stuff like daylight savings time wouldn’t work correctly. In addition other places in our app sometimes got confused if your configured timezone in the application was different from your system timezone.

  This bugfix should fix 99% of all those issues. We believe that it will drastically improve the reliability of Sunbird’s or Lightning’s time reporting and will also reduce support questions. Thanks go to gekacheka for providing the patch and to Clint for reviewing it.

• Bug 393395: Offline Support infrastructure: Synchronization interfaces
  In the past if you were working with remote calendars, you could only use Lightning or Sunbird when you were online. With this patch we’ve made the first step into the world of offline support. Please note that the current state of offline support is still considered experimental. But it should already work in most cases. Thanks go to Daniel and Philipp, who implemented and reviewed this.
• Bug 402518: Enhance storage provider to store foreign timezones
  The issue that this bug fixes is probably the most reported bug for Lightning and Sunbird to date. Until now, our apps would not recognize the timezone definitions in an .ics file, that had been created by other apps (like Outlook, iCal, Evolution, etc.). The effect was, that our apps would go berserk and simply assume that the timezone would be GMT (Greenwich Mean Time) or that there was no timezone mentioned in the imported file at all. That lead to events being displayed at the wrong time. A pretty serious issue for a Calendar application to be honest.

  This bugfix should fix this issue once and for all. However timezones are a delicate thing and it’s easy to miss someting. Therefore we could need some help in testing current nightly builds, so that we’re not in for a big surprise once 0.8 is released. Nevertheless we believe that it will drastically improve the reliability of Sunbird’s or Lightning’s time reporting and will also reduce support questions. Thanks go to Daniel for fixing this beast, that has plagued for such a long time and to Clint for reviewing the patch.

• Bug 408727: Monthview is slow in sorting events
  In the past we have heard some reports of Lightning or Sunbird being slow with larger calendar files. We are currently investigating the roots of the performance issues. One of the first results of this investigation is this patch. We noticed that we were doing unnecessary complex calculations when building up the month view to display a calendar. While this fix alone will not suddenly make the app Lightning-fast, the positive effect should still be noticeable. Thanks go to mvl for providing the patch and to Mickey for reviewing it.
• Bug 411690: Avoid unifinder startup load
  This is another case of us doing unneccessary work. In the past we would always update and refresh the unifinder, regardless of whether it was displayed or hidden. From now on, we will only update and refresh the unifinder when it is active. So if you don’t use it at all or only sometimes, we will use the cycles of your computer more effectively. Thanks go again to Philipp for implementing this and to Mickey for reviewing the patch.

That’s it for today. Tomorrow I’ll present to you our recent improvements in the front-end and the UI. Stay tuned!

WOW! Just nine days have passed since the last status update and 44 bugs have been fixed in that time period. A lot of of those bug fixes fix important and/or longstanding issues and deserve special attention, but if I put everything into this posting you’ll probably need a few hours to read through this post :).

Our resident GData hacker, Philipp, tells me that as of now the latest nightly builds of the Provider for Google Calendar extension support recurring events.

Here are some details:

• Extension nightlies containing the necessary patch are availabe on http://gdataprovider.mozdev.org
• This only works on Lightning and Sunbird nightly builds. Sorry 0.7 users, you’ll have to wait until the 0.8 release comes out.
• In the case that the deletion of a recurring event is not working, this may be due to a known bug on the Google side. Please test with another timezone.
• Philipp hopes to release his next version (0.4) of the Provider for Google Calendar extension at the same time that Lightning and Sunbird 0.8 come out. Release 0.4 will contain recurrence support.

Any help in testing this stuff is greatly appreciated by Philipp and the whole Calendar community.

Welcome to the first status update in the new year 2008! I hope you all had a good time getting into 2008. I certainly did :-) Still, we have been busy over the christmas holidays and the Lightning/Sunbird developers have fixed quite a few bugs on the road to our 0.8 release.

Two bug-fixes are worth mentioning:

• Bug 402177: Add functionality for hiding the unifinder easily
  The event list and search functionality (known among developers as the unifinder) can now be easily enabled or disabled by a toolbar button or the application menu. This should make working with the unifinder much more comfortable for our users.
• Bug 410168: Circular reference in timezone references
  A lot of people have complained about the excessive memory use of Lightning or Sunbird when using remote calendars. We believe that we have found one of the causes (if not the cause) of this huge memory leak and have fixed it. Thanks go to mvl for identifying this issue and to both mvl and Daniel for fixing this bug.

Here is the list of all the 16 bugs fixed since the last status update:

• Bug 382121: Use a javascript implementation of propertybags
• Bug 400949: Build Lightning with Sunbird
• Bug 402177: Add functionality for hiding the unifinder easily
• Bug 405007: Enable unit tests on Trunk tinderboxen – Update Makefile
• Bug 409526: Use a for loop instead of Array.some to make queryinterface a bit faster
