Summary0007809: Filter "none" on custom fields doesn't work
DescriptionWhen filtering on a custom field and choosing the value [none], the result is empty.

The reason is that there's no entry in the mantis_custom_field_string_table for empty lines (except if the field was first filled and then updated to empty).
Steps To ReproducePre-requisites :
1 - Create a custom field as administrator in [Manage custom fields]
2 - Add this custom field to a project in [Manage project]
3 - Create an anomaly in this project and let the custom field empty

Reproducing :
1 - In view issues, select [none] as the value to filter on for this field
2 - Click on Apply Filter
3 - See the empty result
Additional InformationThis could be solved by a special query for the [none] value like :

SELECT ... FROM mantis_bug_table WHERE bug_id NOT IN (SELECT DISTINCT(bug_id) FROM mantis_custom_field_string_table WHERE field_id="...")

Here is a patch that correct this problem.

In fact, there were two problems :

 - no line in the table for bug added before the custom field was added in the project (solved thanks to the SELECT ... WHERE id NOT IN (...))

 - no result at all because of a wrong comparison between META_FILTER_NONE and $t_filter_member

Sorry, I made a mistake in the first patch. The second one is the good one.

I finally had a chance at reviewing your patch.
You are definitely right on the diagnosis and the proposed fix works, but I reworked the patch a little becasue I did not like too much the $t_first_time usage (I know, it's not your faukt since you copy/paste it...) I'm attaching the reworked patch here, please test it and let me know if it also works for you.

One question; the query you proposed in "Additional Information" had a DISTINCT clause: is there a reason why you dropped it in the proposed patch?

It seems fine to me (and yes, the use of an array and implode is more elegant ;) ).

I think I dropped the DISTINCT clause because there can be only one row for a given couple of bug_id and field_id, so it was useless.

In the meanwhile, I become aware thart the nested query syntax could be problematic for the cross DB goal of mantis (and even in MySQL was introduced in v4.1, while we are going to require 4.0)

Do you think that doing 2 separate queries would be detrimental to performances and/or RAM usage?

@giallu: I thought we were going to be requiring MySQL 4.1 specifically for the reason of subquery support?

I will ask again on -devel

Shouldn't / doesn't ADODB handle subquery support?

I wish I knew...

anyway, Victor gave me the OK to use subqueries, so 1.1 will have a dependency on MySQL 4.1 and I can commit the fix as is.
