Merge lp:~bac/launchpad/bug-419930 into lp:launchpad

[Brad Crittenden]

Rework merge request pages

[Brad Crittenden (bac)]

= Summary =

Users can choose to hide their email addresses and we should always honor that
request. Currently anyone who attempts to merge a person with hidden email addresses
is shown all addresses for that user.

Also did a drive-by fix to the person picker vocabulary that was not catching an
Unauthorized exception which prevented people with hidden emails from being selected
in the picker.

== Proposed fix ==

Rather than displaying the addresses and letting the user choose which ones to
contact we should just show a count of addresses and send notification to them all.

== Pre-implementation notes ==

Quick call with Curtis as a sanity check of the approach.

== Implementation details ==

As above.

== Tests ==

bin/test -vvm lp.registry -t merge-people.txt

== Demo and Q/A ==

Hi Brad,

This looks pretty good. I have only a few comments/suggestions and one
request for a missing test.

Does that mean we can't merge people with hidden email addresses unless
we know their Launchpad ID or email address?

Currently we cannot use the picker to select people with hidden email addresses. But you can merge them by typing in the ID into the field on the form.

I have discovered Edwin is working to redo the way these pickers are working and my drive-by change would soon be replaced by his work. Therefore I'm going to back out this portion of the change and just wait for his more thorough fix.

This typo was pre-existing. I looked to see if it existed elsewhere and found and fixed six other occurrences.

Ok, do you mind filing a bug and assigning it to him, just to make sure
it's not forgotten?
