Cli does not remove values from multi-value fields

RT Developers
1

I brought this up with rt-bugs (ticket #14423) and it was suggested I
bring it up here, too.

Details are in the ticket, but the upshot is the cli does not deal with
multi-value custom fields very well. If you try to remove a value from
the list, unless it is the first one in the list, it is not removed.
Also, spaces are added to list values when a value fails to be removed.

I also noticed that when I try to add a value to a multi-value field,
spaces are added to the front of the added value, much like in the
erroneous delete I describe in the ticket.

My best guess is that there is a bug somewhere in the vsplit and/or
vpush subs, but I am not quite knowledgeable in perl enough yet to say
for sure.

We use the cli extensively in conjunction with custom fields in our
automated processes, so finding a fix for this is rather important.

I would be happy to help fix this in any way I can.

Thanks.

I think I have managed to kill this bug. A diff patch for the rt cli is
attached.

There were two parts to the bug:

  1. multi-value fields were not getting parsed properly when attempting
    to delete a value from the list
  2. when adding values back to a multi-value field, additional space
    characters were inserted before the individual values

Part 1 was because of vsplit() splitting the values on a newline char
when they were actually being returned in the REST form as
comma-separated values. My first fix was to just split on commas, but I
then added the newline char back to the regex match. This should
provide flexibility and preserve any legacy code from other users.

Part 2 was in Form::compose() where new values were added back to the
multi-value list string separated by a comma and then a space. By
removing the space character from the append string, extra spaces are no
longer inserted.

This patch works with my own testing. Please try it for yourself and
make sure I haven’t broken any other functionality.

I hope others find this useful and that it is considered for inclusion
in the next release.

Looks like these patches aren’t included in 3.8.8. Guess they’ll be in
3.8.9 then?

Thanks.
