23370 - Migration: remember_selected_message true doesn't migrate right

Status: VERIFIED FIXED

(MailNews Core :: Profile Migration, defect, P3)

Description

[laurel]

Using jan06 builds on all platforms

The pref for remember_selected_message doesn't show in 4.x prefs.js if the pref
value is true (enabled).  If a profile with this pref enabled in 4.x is
migrated, the 5.0 UI will not pick up the pref enabled state (and doesn't show a
pref line in the prefs.js file).

Note:  if the pref is enabled/checkmarked in 5.0, the enabled state will stick
in UI and a line will be written to prefs.js with value set to true.

1.  Open a profile in 4.x.
2.  Edit|Prefs|Mail and Newsgroups. Enable/checkmark the preference "Remember
the last selected message" and confirm OK. Exit 4.x.
3.  Open 4.x prefs.js file and note there is no pref line for the relative pref:
remember_selected_message. (If the 4.x pref is disabled/false there would be a
prefs line.)
4.  Migrate the profile to 5.0, go to mail.
5.  Check the preference in the UI -- the pref is disabled/not checkmarked.
6.  Check the 5.0 prefs.js file -- there is no prefs line.

Actual result:  The pref enabled in 4.x is not enabled in 5.0 after migration.
User must set the pref to enabled state in 5.0.

Expected result:  The pref enabled in 4.x should migrate to enabled state in
5.0.

fixed.  the problem was we never defined a default for this pref in mailnews.js

Now the UI is correctly enabled after migration.  There is still no pref.js line
written for the case of enabled/true.

OK using:
2000-01-18-11m13 commercial build on NT 4.0
2000-01-18-11m13 commercial build on linux 6.0
