Status: RESOLVED DUPLICATE of bug 276585

(Calendar :: General, defect)

Description

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.8b4) Gecko/20050910 SeaMonkey/1.0a

Missed alarms should be suppressed or at least suppressable when a calendar is
imported. Related bugs: 138223 and 177279. Many people like to see missed
alarms, however after a calendar is imported there are many missed alarms that
nobody will want to see. Possible solutions:
1. Turn off "Show missed alarms" preference on import; remind user to turn it
back on if desired.
2. Ask user whether to import events that have already happened. If yes, then do
what is suggested in 1 above.

Reproducible: Didn't try

Steps to Reproduce:
I uninstalled Mozilla 1.8a5 including calendar component. Next, I installed
SeaMonkey 1.0a [Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.8b4)
Gecko/20050910 SeaMonkey/1.0a], and then Sunbird [Mozilla/5.0 (Windows; U;
Windows NT 5.0; en-US; rv:1.8a5) Gecko/20050203 Mozilla Sunbird/0.2]. Then, I
imported my old calendar into Sunbird.
Actual Results:  
I received over a hundred missed alarms. I started acknowledging them, but
realized it was futile, so I pressed the "Acknowledge All Alarms" button, and
the alarms disappeared, but then they all reappeared after about an hour or so.

Expected Results:  
1. I should be asked whether I want to get hundreds of missed alarms.
2. If I press the "Acknowledge All Alarms" button, then they alarms should not
appear again.

The day after I pressed the "Acknowledge All Alarms" button they
all reappeared again. When the 141 alarms first appeared
immediately after the import, I first startd acknowledging them
individually, then realized it would take too long and pressed
the "Acknowledge All Alarms" button. All the alarms reappeared
after some time. Then, I acknowledged all of them individually,
thinking there might be a problem with the "Acknowledge All Alarms"
button. My computer was on overnight, and this morning 140 of the
141 alarms appeared again. This time I pressed the "Acknowledge
All Alarms" button. We'll see what happens.

My computer was on overnight, and this morning
143 missed alarms appeared. I pressed the
"Acknowledge All Alarms" button again. I won't
report this anymore, but it appears to be
repeating every day.

Note that the entire alarm system has been redone for 0.3/nightly builds.  It
isn't 100% functional yet (missed alarms are never fired, I think), but further
testing in 0.2 won't help very much. :-(
