1692181 - After release 78.6.1 exceptions of recurring events are not shown anymore

Status: RESOLVED DUPLICATE of bug 1686466

(Calendar :: Internal Components, defect)

Description

[Joffe Gruenfron]

Attachment: TestData.zip

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:85.0) Gecko/20100101 Firefox/85.0

Steps to reproduce:

In Thunderbird >= 78.6.1 create new local calendar named Test. Import TestMe.ics contained in TestData.zip and import all events. Open calendar monthly view and head for February 2021. This imports a recurring event from 2021-02-05 to 2021-09-30 from 14:30 to 15:30 each Friday. Also contained is an exception to modify one event from 2021-02-12 to 2021-02-15 from 15:30 to 16:30.

Actual results:

After import the calendar is shown correctly (see CalendarOK.png). After closing and re-opening TB >= 78.6.1 the exception has vanished (see CalendarBAD.png). However, when performing same steps with TB 78.6.0 calendar remains correct. Also when sharing same calendar data local.sqlite between 78.6.1 and 78.6.0 the latter shows correct calendar whilst 78.6.1 shows the wrong one.

Expected results:

The calendar should be shown correctly. I compiled 78.6.0 and 78.6.0 and found the problem is introduced with fixing bug 1664731 by change set 95c92a2f9fbc5260649a62602ca7b0e1575594c3

Probably bug 1686466: that's not strictly tasks I think, even if they are the ones showing it the most.
Please try 78.8 when that's out next week.

Thanks, I can confirm that applying bug1686466v2.patch to my 78.6.1 source tree fixes the problem \o/. I'll check 78.8 when released.
