Selected / Sat Upon reports incorrectly and confuses prim count

Linden Lab Issue ID: DEV-12869


 Description  « Hide
In the quest to trace down errant prims, I've noticed that the "Selected / Sat Upon" is highly erratic in what it reports. As an example, on a 4096m plot with no avatars present, this figure reported 102 prims as being selected/ sat upon. On the next pass 5 minutes later, it showed zero.

Since this figure affects total prim count, this makes it very difficult to track total prims on a parcel. I question that this figure is even necessary. IMO, it could be deleted entirely and replaced by TOTAL PARCEL PRIM COUNT for a more accurate (and useful) figure.

I have marked this MAJOR because it is a royal pain trying to police a sim for proper prim usage under the current situation.

UPDATE: Discovered a kluge-fix: Edit/select every item on the plot and exit edit. This sets Selected/Sat Upon back down to 0. (A temporary fix, but still a pain).

The two enclosed photos show a striking example of this bug. The first shows "Set to group" as 429 and "Selected/Sat Upon" as 1059.
The second photo was taken after the above trick was used, showing Selected/Sat Upon as 0 and a correct "Set to Group" of 1488.

IMO this confirms that it IS a bug, and not just a discrepency or misreading. Second Life appears to just be losing track of what is selected/sat upon.

And again, I question whether that figure is even warranted. What practical use does it have? None, I think.

Well... at least I WOULD upload photos if I could figure out how to get the photo uploader to work. Grrrr. Anyone ever heard of drag and drop or BROWZE? Grrrrr...

I believe the purpose is to show which objects cannot be returned. If so a show button might be nice also.

eren padar added a comment - 19/Mar/08 08:24 PM
That seems odd. I can delete an item I own that someone is sitting on. So why shouldn't a land owner/sim owner be able to return anything they don't want on their land and sim, regardless of whether someone is sitting on it or not? Not arguing with you. I've seen a lot of strange stuff on SL that seemed to have no rhyme nor reason. The "selected / sat upon" just seems like one of 'em

Harleen Gretzky added a comment - 19/Mar/08 08:57 PM
You are correct, you can return sat upon objects, so no idea the purpose.

Lex Neva added a comment - 19/Mar/08 09:59 PM
Harleen was close; it's to keep track of which objects won't be returned by autoreturn. I've noticed that the figure seems arbitrarily inflated on my land as well. I suspect that sometimes the sim loses track of when objects are no longer sat on or selected.

nika talaj added a comment - 20/Mar/08 02:13 PM
Here's a thread of folks who have also noticed this:

http://forums.secondlife.com/showthread.php?p=1915148

Does anyone know for a fact that this number being hugely inflated (as it is on my land as of yesterday) has no negative consequences?


Mercia Mcmahon added a comment - 21/Mar/08 03:07 PM
No this is not about what has been sat upon or selected but the system going wonky. Urbana Spes has for a couple of days been reporting that 4147 (number varies but always 4000+) of 8865 objects are selected or sat upon. There is no way that this is true. We are talking about a city rezzed by software that covers every last metre of the region. There is a tiny parcel used to send anyone loging into the region at 128,128,0 to be sent to the city (which is at 300m), that aprcel reports 8 out of 8 sat upon or selected. The third and final parcel is a dance club that reports 492 out of 515 sat on or selected. Regardless of the two smaller parcels there is no way that I or others have previously selected 4000+ objects in the city, especially as major redevelopment work would not be done with selects, but by re-running the sim rezzer software.

Negative consequences? YES!
Anyone renting land needing to track prim counts for one. Group owned, or any object that need to have a group tag to be rezzed on your rental property once its dumped into the "selected/sat upon" category and WILL NOT be counted anymore as a group object.

The use of "selected/sat upon" is as it states and nothing more. This feature could be used for moving builds you know have a certain amount of objects or for pruning areas of a parcel of objects. If I need to move a house that I know has 83 prims and I check by viewing selected /sat upon, I'll know I have everything.

Sometimes you all have had the experience of accidentally selecting a bunch of objects. It appears that these objects are not reverting to zero and I suggest the cause of the over abundance of that count.

I had Kyle Linden reset a region to correct this. It seemed to work at first but now its starting to happen again. The problem with this bug is that objects that are dumped into the "selected sat upon category" are no longer being counted as group owned objects. That simple. Makes it difficult to count prims.

Your selected sat upon should always zero unless you selected/ sat upon some objects BEFORE clicking on the about land settings. Once you exit about land and select about land< objects again it should revert to zero. What I am noticing is that certain regions or parcels within regions again are starting to stack up the selected sat upon objects area.


Astro Raymaker added a comment - 23/Mar/08 12:22 PM
It appears as though the "Primitive on parcel" count is correct, it's just the way the counts are grouped that is incorrect ("Owned by parcel Owner" and "Set to Group") are low and "selected/sat upon" is high. And selecting all items on your land and closing edit will either lower or raise the "sel;ected sat upon" count, so that kluge fix doesn't always work.

Mercia Mcmahon added a comment - 24/Mar/08 05:27 AM
I can confirm that this is definitely not related to the system not released back statistics for what you have previously selected. Urbana Spes City is now stating that there are 6342 prims selected or sat on, there is no way that I have selected 2000 prims in the last two days.

Soft Linden added a comment - 31/Mar/08 12:28 PM
I'm seeing this on my resi parcel with 1.19.1.4 as well.

stimpy tripp added a comment - 01/Apr/08 06:07 PM
Hi: This is affecting me too. Thanks for the workaround Eren. BTW, should this be in the viewer area of the jira? Wouldn't the info come from the Server end of things? Just asking.
Thanks to whomever fixes it!

Appears fixed in Server 1.20.0.83683 sims.

blaccard burks added a comment - 04/Apr/08 03:34 PM - edited
This issue is not fixed and has not been resolved. Selected sat upon objects are accumulating and not being released. I curious as to why it was listed as "resolved".

Harleen Gretzky added a comment - 04/Apr/08 03:55 PM
It appeared fixed after the server update to 1.20.0.83683, but appears to have returned.

blaccard burks added a comment - 05/Apr/08 10:21 PM
All one has to do on any parcel is bring up the object data in the about settings. You would be surprised to find out how many parcels have this data corrupted.

Beezle Warburton added a comment - 13/Apr/08 07:01 AM
Possibly just a duplicate of SVC-516 with symptoms described differently – when prims fail to rez/derez properly is when the selected/sat upon goes awry.

lorissia fraisse added a comment - 14/Apr/08 03:41 PM
Our Sim also has this problem . Over 6000 prims are selected / sat upon according to the objects tab in the About Land.

Mercia Mcmahon added a comment - 15/Apr/08 06:28 AM
No Beezle, not a duplicate of that very different issue. I get the selected/sat upon account rocketing even though it is highly unlikely that between reboots to give the figure before the reboot I just did, that 3170 prims failed to rez or de-rez. The selected/sat-upon number does go to zero with a reboot. SVC-516 nad this issue appear to be separate issues that you have maybe confused because you have seen the prim count go awry while suffering those rezzing issues. As the medieval philosophers said "We ought to distinguish without separation so that we might re-untie without confusion." I think that we need to distinguish these two issues, they might be related but they are not duplicates.

Torin Golding added a comment - 15/Apr/08 04:17 PM
Plot 1 in my ROMA Subura sim has only 5 objects on it, as seen when I hit the count button on the land window. But the land records 35 prims on the plot, which is confusing the prim counting rental prim, giving prim overage notices to my renters.

Beezle Warburton added a comment - 15/Apr/08 04:54 PM
Not sure if this is the appropriate entry for this – let me know and I can move this set of comments elsewhere.

I had 400+ Selected/Sat Upon prims in Yoonseul. and hadcollisions where the prims used to be.

Additionally, the prim counts were off:

Simulator Usage: 545/937 ( 392 free)
Parcel Supports: 527
Primitives on Parcel: 534
Owned by Parcel Owner: 37
Set to Group: 73
Owner by Others: 0
Selected/Sat Upon: 424

This was cleared up with a region restart (ticket 4051-4691107) - howerver, as of today (April 15), I again have:

Simulator primitive usage: 540 out of 937 (397 available)
Primitives Parcel Supports: 527
Primitives on Parcel: 529 (I have more than one parcel on this Sim, so this is okay)
Owned by parcel owner: 73
Set to Group: 74
Owned by others: 0
Selected/Sat Upon: 382

This is possibly being fixed under http://jira.secondlife.com/browse/SVC-1910

"Assigning this to Kelly Linden, who was working on it Friday and will hopefully finish it soon. The current theory is that this is caused by a "selection bit leak" – objects are getting selected but not unselected. The best way to verify this is probably to pay attention to the "selected objects count" in the parcel object tallies.

There is sanity code already in the SL simulator that tries to scan for lost selections but if this really is a selection bit leak then it would appear to not be working correctly, or else is not aggressive enough and waits too long.

BTW, I think that when shift-drag-copying... the object that is moved and remains selected is the original, and the one that remains in place is the copy. You should be able to verify that by adding a script that does certain things on_rez()." – Andrew Linden

I believe this is related to the rotating prim stoppage, re: SVC-1910. A fix for that is planned for 1.21.

kelly linden added a comment - 29/Apr/08 08:20 AM
I believe this was caused by the 'selection bit leak' issue that was also breaking llTargetOmega objects - I think it should be fixed now with the currently deployed 1.21 Server

eren padar added a comment - 29/Apr/08 09:02 AM
llTargetOmega being fixed as well? WOOHOO! Two birds with one stone (hopefully).

Thanks for letting us know, Kelly. : )


Mercia Mcmahon added a comment - 29/Apr/08 09:35 AM
I confirm this is fixed, on a region that was erroneously reporting numbers of 5000+ selected or sat upon, it now says 1.

I have 8 ghost prims on my parcel this evening.
http://slurl.com/secondlife/St%20Lion/140/8/67


kelly linden added a comment - 04/May/08 07:11 PM
Meredith: can you elaborate? Do you mean that there are 8 more objects in the parcel object counts than are actually on the parcel? Or that there are 8 objects that always show as selected? Or something else?

I don't think this is the jira item for ghost tasks - this was a jira item for the selected / sat upon count in the parcel properties window being wrong. What exactly are you reporting as a bug?


eren padar added a comment - 05/May/08 12:48 AM
Greeting Kelly. You're right, the ghost prim thing is a whole nuther bug, but I know what Meredith is speaking of.

Since Havok 4, I've noticed "ghost prims" regularly. These apparently are builds that were deleted by the builder... but for some reason their placemarkers (or something) still hangs around. The prims can't be seen (not event with ctrl alt T), they can't be selected, but you try to walk and you bump right into them. Sim has to be reset to get rid of them.


Meredith Staheli added a comment - 05/May/08 08:03 AM
hi eren, thank you for your elaboration and explanation. =)

hi, kelly, these are the detailed steps:

1) I rezz 8 prims on the ground
2) trying to delete them all at once
3) those 8 prims disappeared roughly after 45 second
4) the hour glasss was still showing on my screen for more than 2 minutes
5) I checked the Object tab in About Land

Expected result:

  • Selected / Sat upon should be zero
  • Simulator primitive usage should be 117 out of 117

Observed result:

  • Selected / Sat upon was showing 8
  • Simulator primitive usage was showing 8 out of 117

then I cleared network cache and relog:

1) I checked the Object tab in About Land again

Expected result:

  • Selected / Sat upon should be zero
  • Simulator primitive usage should be 117 out of 117

Observed result:

  • Selected / Sat upon is showing zero
  • Simulator primitive usage is still showing 8 out of 117
  • Set to Group is now showing 8
  • no prims are visible on the parcel
  • I can bump into them very easy since they are all 8m x 8m x 1m
  • I tried to return them a few times but I was not successful

This is very annoying we have to wait for LL to restart the sim every time.
If you need further info or my assistance, please feel free to contact me in-world or thru JIRA.


kelly linden added a comment - 05/May/08 08:12 AM
I am going to resolve this issue again, the bug Meredith is reporting is not the same bug. There are other issues open for Ghost Prims such as SVC-255. Please add your comments there, thank you.

Ghanie Lane added a comment - 09/May/08 01:54 PM
Ugh, this thing hit me today but that "workaround" of placing all objects into the edit window is NOT resetting my value.

Ghanie Lane added a comment - 13/May/08 03:55 PM - edited
This is NOT fixed!!! Can't you make that not included in the prim count until you can get it to maintain an accurate count?

My selected/sat upon number has been 144 since FRIDAY and I can't use my in-world tools on 56 prims!

Simulator primitive usage: 529 out of 585 (56 available)
Primitives parcel supports: 117
Primitives on parcel: 166
Owned by parcel owner: 22
Set to group: 0
Owned by others: 0
Selected / sat upon: 144

I tried selecting all object in the edit window, clearing cache, etc ... none of that is working for me.

This is not the Ghost Prim jira item. Please either find an issue about ghost prims or create one. Thanks.
