Packagers AFK in pkgdb

I just wanted to point out a small feature added to pkgdb recently.

Basically, it integrates with the vacation calendar of fedocal to show on the packager's info page if the person is on vacations or not.

If you are dealing with someone who is slow to answer on bugs, irc or emails, it may give you an insight as to why that is.

Note: I am in no way saying that Paul is slow to answer bugs, irc or email, and have merely used him to illustrate my thoughts following up on his post about the Red Hat summit and I shall not be held responsible for any variations in Paul's response time :-)

The Joy of timezones

Today, I was looking at fedocal as I found out it could not import its own iCal files.

Well, to be exact, the import worked fine but then it was not able to display the meeting. The source of the issue is that the iCal output is relying on timezone name such as EDT or CEST while fedocal actually expects timezone to be of type US/Eastern or Europe/Paris.

So I went looking for a way to convert the acronyms to real timezone.

I finally found out the following script:

import pytz
from datetime import datetime

timezone_lookup = dict()
for tz in pytz.common_timezones:
    name = pytz.timezone(tz).localize(datetime.now()).tzname()
    if key in timezone_lookup:
        timezone_lookup[name].append(tz)
    else:
        timezone_lookup[name] = [tz]

for key in sorted(timezone_lookup):
    print key, timezone_lookup[key]

Which led me to discover things like:

  IST ['Asia/Colombo', 'Asia/Kolkata', 'Europe/Dublin']

The Indian Standard Time and the Irish Standard Time have the same acronym

but also:

  EST ['America/Atikokan', 'America/Cayman', 'America/Jamaica', 'America/Panama', 'Australia/Brisbane', 'Australia/Currie', 'Australia/Hobart', 'Australia/Lindeman', 'Australia/Melbourne', 'Australia/Sydney']

So how to handle this?

The only solution I could came up with is relying on both the acronym and the offset between that timezone and UTC

Adjusted script:

import pytz
from datetime import datetime

timezone_lookup = dict()
for tz in pytz.common_timezones:
    name = pytz.timezone(tz).localize(datetime.now()).tzname()
    offset = pytz.timezone(tz).localize(datetime.now()).utcoffset()
    key = (name, offset)
    if key in timezone_lookup:
        timezone_lookup[key].append(tz)
    else:
        timezone_lookup[key] = [tz]

for key in sorted(timezone_lookup):
    print key, timezone_lookup[key]

And corresponding output:

...
('EST', datetime.timedelta(-1, 68400)) ['America/Atikokan', 'America/Cayman', 'America/Jamaica', 'America/Panama']
('EST', datetime.timedelta(0, 36000)) ['Australia/Brisbane', 'Australia/Currie', 'Australia/Hobart', 'Australia/Lindeman', 'Australia/Melbourne', 'Australia/Sydney']
...
('IST', datetime.timedelta(0, 3600)) ['Europe/Dublin']
('IST', datetime.timedelta(0, 19800)) ['Asia/Colombo', 'Asia/Kolkata']
...

So much fun...

Fedocal 0.7

This morning I released fedocal version 0.7.1.

With this version comes a number of new features which I thought would be nice to advertise a little :-)

The main calendar view & the menu

The main calendar view has had two additions:

  • a pop-up stipulating if there are meetings present that week that are not displayed in the current window (for example, if you're seeing the meetings from 8am to 6pm and there is a meeting at 7pm, or at 4am).
  • shortcuts to interact more easily with the calendar. These shortcuts contains three actions: Add a meeting, switch to list/calendar view, iCal feed.

The menu now highlights the calendar you are looking at to make things easier on you.

The list view

When viewing a calendar as list, fedocal will now automatically scroll down to the display the meetings of today or the future meetings.

In addition, this page also has the three shortcut buttons mentioned above (add meeting, switch view mode, iCal feed).

The detail view

We have added three new features in the page showing the details of a meeting

  • permalink: when the user clicks on the pop-up showing the details of a meeting the url is updated to provide a permalink to that specific meeting. This allows one to copy/paste the url and send it to someone.
  • countdown: with the help from mpduty we have added a countdown in the meeting detail view showing the remaining time before the meeting starts. This can nicely circumvent the timezone conversion if you are not logged in fedocal and want to know when a meeting starts
  • UTC titles: if you hover over the dates/times with your mouse, the date/time will be shown in UTC which is always handy as in our community UTC remains quite often the most used way to communicate date/time.

I would like to take here the opportunity to thank kparal, ralph, willo, red and lbrabec for their bug reports and RFE that led to all these changes which I think are making fedocal 0.7.1 its best release so far :-)

Fedocal upgrade

This morning I update fedocal to its latest version: 0.4.2, this update brought quite a number of changes, among them:

  • New UI, closer to pkgdb2, nuancier and koji
  • Add location to meeting, so that #fedora-meeting should no longer be a calendar but a location
  • Improved list view
  • Improved window to add a meeting
  • Improved calendar view where the full day meetings are separated from the other meetings
  • Store the meeting in the specified timezone instead of UTC (allows to have a meeting at 2pm/14:00 Paris time all year long, despite of DST)
  • Enable viewing the agenda in another timezone
  • Enable browsing the dates without using the small monthly calendar



I took the opportunity to re-generate the database to make sure all the fields were in sync with the DB model planned. The data was then copied over from the old DB to the new one, which gave some stats about fedocal:

10 calendars added
18 reminders added
236 meetings added



Check it out!
