Bug in RT::Tickets::LimitMemberOf (3.0.12)

I discovered the following issue I do not (yet) have a solution for:

If I merge to tickets with children, say,

#100
with child #101

#200
with child #201

-> merge #200 into #100

I expect something like

#100
with child #101 and #201

Indeed, if I do

my $members = $Ticket->Members;
while (my $link = $members->Next) {
next unless($link->BaseURI->IsLocal);

}

I get both tickets listed.
However, using

my $MyTickets = new RT::Tickets ($session{‘CurrentUser’});
$MyTickets->LimitMemberOf($Ticket->Id);
while (my $link = $MyTickets->Next) {

}

I only get #101. Looks like a bug in “RT::tickets::LimitMemberOf”.
Anyone noticed this before and/or got a fix?

What version of RT?

see subject: 3.0.12
I noticed this as RTIR uses the later while RT the first function to
list children.

-> this apparently affects also 3.2.3, I did not see any code changes
from 3.0.12 in the relevant parts.

Some additional info: here is the table extract (table “Links”) from the
DB and some tickets with children that have been merged into 1963:

Shouldn’t be LocalTarget be rather 1963 as well? Looking through the
whole table, I only see “Target” mismatches with “MemberOf”:

Is this rather a problem of the “Ticket->MergeInto” function? Please let
me know, so I can start to fix it at the right place. Don’t want to make
a mess of rewriting it.

In Link_Overlay, a link is created with both “LocalTarget” and “Target”,
however, only the later is updated by “Ticket->MergeInto”:

Link->SUPER::Create( Base => $base->URI,
Target => $target->URI,
LocalBase => $base_id,
LocalTarget => $target_id,
Type => $args{‘Type’} );

Target->MergeInto:

# update all the links that point to that old ticket
my $old_links_to = RT::Links->new($self->CurrentUser);
$old_links_to->Limit(FIELD => 'Target', VALUE => $self->URI);

while (my $link = $old_links_to->Next) {
    if ($link->Base eq $NewTicket->URI) {
        $link->Delete;
    } else {
        $link->SetTarget($NewTicket->URI);
    }

}

(same for Base)

Tickets->Limit seems to use the Local… entry:

my $matchfield = ( $value =~ /^(\d+)$/ ? “LocalTarget” : “Target” );
[…]
my $matchfield = ( $value =~ /^(\d+)$/ ? “LocalBase” : “Base” );

while enumerating the URIs obviously gives the correct results.

from 3.0.12 in the relevant parts.

Does 3.4 behave better?

I do not have it installed, but will pull the source, configure it, and
compare the relevant parts. Now I know what to check for :wink:

Some update:
The following MySQL commands show the issue:

mysql> SELECT Id,Target,LocalTarget,Type FROM Links WHERE Target LIKE
"fsck.com-rt://sun.com/%" AND Target !=
concat(“fsck.com-rt://sun.com/ticket/”, LocalTarget) ;

mysql> SELECT Id,Base,LocalBase,Type FROM Links WHERE Base LIKE
"fsck.com-rt://sun.com/%" AND Base !=
concat(“fsck.com-rt://sun.com/ticket/”, LocalBase);

-> Obviously, change “sun.com” to your domain prefix from RT::URI.

The following MySQL commands FIX the issue:

mysql> UPDATE Links SET LocalTarget =
replace(Target,‘fsck.com-rt://sun.com/ticket/’,’’) WHERE Target LIKE
"fsck.com-rt://sun.com/%" AND Target !=
concat(“fsck.com-rt://sun.com/ticket/”, LocalTarget);

mysql> UPDATE Links SET LocalBase =
replace(Base,‘fsck.com-rt://sun.com/ticket/’,’’) WHERE Base LIKE
"fsck.com-rt://sun.com/%" AND Base !=
concat(“fsck.com-rt://sun.com/ticket/”, LocalBase);

Code change for Ticket::MergeInto still outstanding - I will check 3.4
before making any changes.

RT 3.4 is not affected. It sets both, LocalTarget and Target (same for
Base). Actually, the code change below is already the fix (after
s/$MergeInto/$NewTicket/ :slight_smile:
