No support for BlackBerry Z10 and newer devices
-----------------------------------------------
I don't have one of these devices, and from what I understand,
the protocol is completely different. User reports
would be appreciated.
Desktop GUI does not display or edit some recurring calendar entries correctly
------------------------------------------------------------------------------
Some recurring calendar entries, such as birthdays, have 0 value
start and end times, but use the recurring mode YearByDate to
specify the day of the birthday. This is not handled correctly,
if at all, in the Desktop GUI, and merely shows todays date
in the Start and End fields, and does not display the month or
day number of the recurring YearByDate at all.
This requires a GUI modification, and additional code to handle the
special case.
Tasks database self-corrupts on many devices
--------------------------------------------
If you extract a Tasks record, and then write it back via
SetRecordByIndex(), on many devices that I tested, it ends up
corrupting the record on the device, and the GUI on the device
appears messed up. (It shows the first few fields twice)
Such a corrupt record also loses the due date.
This appears to be a bug in the device firmware.
The workaround, when working with the Tasks database, is to
first DeleteByIndex() and then AddRecord() via the Desktop mode class,
using the same record ID. This works, but is unfortunately
cumbersome.
See the Desktop GUI and the opensync plugins for examples of this
workaround.
Ideally, we should test a Tasks sync on Windows, and see how
the Windows software handles this. There may be some protocol
changes that will be needed in future Barry versions.
Dates before 2007/01/01 use modern DST rules
--------------------------------------------
This is a device firmware issue. Most devices that I've tested
use modern DST rules (i.e. DST begins second Sunday in March)
for all dates, even though these new rules only came into effect
in 2007. So dates in 2006 and earlier have a window of innaccuracy,
since dates are given to Barry in UTC, converted to time_t, and most
computer systems will then convert that time_t to local time using
the old DST rules, and be an hour off.
Barry does nothing to workaround this bug, since most dates
are used in Calendar and Task apps, which usually only matter
for modern dates. In other words, you use the Task and Calendar
apps to remind yourself of future appointments, not the past.
This appears to be the logic that RIM used as well, since the
device seems to only have one DST rule, and doesn't care about
historical rules.
