Tim Donohue commented on DS-946:
--------------------------------
This issue was discussed in Developers Mtg on Feb 15. Unfortunately we were
unable to locate a volunteer to investigate possible fixes.
So, this issue still needs a volunteer.
[20:00] <kompewter> [ https://jira.duraspace.org/browse/DS-946 ] - [#DS-946]
index-update not updating author browse index - DuraSpace JIRA
[20:02] <tdonohue> this one is a verified bug (see comments) which still exists
on Trunk. Mainly just needs a volunteer to investigate it
[20:02] <mdiggory> browse or discovery?
[20:02] <mdiggory> they say they enabled discovery
[20:02] <KevinVdV> Well I think they are refering to the default DSpace browse
[20:02] <tdonohue> I know traditional browse has this bug. Not sure about
discovery
[20:04] <mdiggory> maybe they should verify that its just browse by replicating
it without discovery enabled.
[20:04] <KevinVdV> Discovert shouldn't have this issue, the reason being when
an item is deleted from the index there is no way to unindex it in the current
browse implementation (correct me if I'm wrong)
[20:04] <mdiggory> the bug still exists in trunk?
[20:04] <tdonohue> mdiggory: I already verified that. I tried it without
discovery (see the final comment). It exist on Trunk with Discovery disabled
[20:04] <mdiggory> k
[20:05] <mdiggory> it should be deleted from browse index as well.
[20:05] <mdiggory> This was something that still remained "hardwired"
[20:05] <KevinVdV> Yes but @ the moment their is no link between a browse
author & the item it belongs to
[20:05] <mdiggory> hardwired in Item itself
[20:05] <tdonohue> anyone care to investigate this? I think we just need
someone to figure out what the underlying issue is and how best to resolve it
[20:06] <mdiggory> IE, all the browse add/update code was moved to a consumer,
but because of an fkey constraint on the db, the delete had to remain in the
Item.delete method
[20:06] <mdiggory> it was a design failure of the Event system
[20:07] <mdiggory> or of Browse itself...
[20:07] <tdonohue> hearing no volunteers to investigate?
[20:08] <tdonohue> ok. Ds-946 summary: Bug has been verified. Still needs a
volunteer to investigate underlying cause & find a fix

[20:09] <mdiggory> My favorite part of this comment...
[20:09] <mdiggory> * Any fix would involve too much work on Browse code that
[20:09] <mdiggory> ** is likely to be replaced soon anyway. --lcs, Aug 2006
[20:10] <tdonohue> mdiggory: that seems to imply it should be removing itself
from the Browse Indexes -- but, the truth is that isn't happening. It only
removes itself from Browse By Title. It never gets removed from Browse By
Author/Subject
[20:11] <KevinVdV> tdonohue: t.b.h. how could it ? the entries in the browse by
author/subject table retain no links to the item, am I right ?
[20:12] <KevinVdV> I may me wrong (not THAT familiar with the browse system)
[20:13] <tdonohue> I don't know to be honest. I'm not that familiar with
everything in browse system either. It just seems wrong to leave empty
authors/subjects around that never seem to get cleaned up properly
[20:13] <tdonohue> I think the key thing here is we just need someone to dig in
deeper here. Hopefully we can find someone to volunteer for Ds-946 offline
[20:14] <tdonohue> ok, i'm going to move on...feel like we're just spinning our
wheels on Ds-946

> Key: DS-946
> URL: https://jira.duraspace.org/browse/DS-946
> Project: DSpace
> Issue Type: Bug
> Affects Versions: 1.7.1, 1.7.2, 1.8.0, 1.8.1
> Environment: Running DSpace 1.7.1 on a Windows server
> Reporter: David Isaak
>
> I am pretty sure this is a bug, but if we have something wrong with our
> set-up then my apologies in advance! I am running DSpace 1.7.1 on a Windows
> server using the XMLUI with Mirage and Discovery.
> When I delete a collection through the Admin UI, the collection and
> constituent items are removed, but links in the author browse index persist.
> When I click on a link, I get the message "Sorry, there are no results for
> this browse." Running the index-update command does not remove the old links
> in the author index.
> Stopping Tomcat and running index-init does fix the problem, but I believe
> index-update is supposed to do this as well.
