2018 SL UG updates 45/1: Simulator User Group

Florence Bay; Inara Pey, September 2018, on FlickrFlorence Bayblog post

Server Deployment Plans

As always, please refer to the server deployment thread for the latest news and updates.

  • On Tuesday, November 6th, the SLS (Main) channel was updated with server release 18#18.10.25.521081, previously deployed to the BlueSteel and LeTigre RCs, and comprising internal logging fixes. It is hopped that these updates will help with some crashing, particularly some regions that get into a crash loop.
  • On Wednesday, November 7th, 2018, the RC channels should be updated as follows:
    • BlueSteel and LeTigre will update to server maintenance package 18#18.11.01.521328, comprising a fix for Animesh land impact calculations – see below.
    • Magnum should be updated to server maintenance package 18#18.11.01.521329, also comprising a fix for Animesh land impact calculations – see below –  and also internal logging fixes.
    • Snack should also receive another iteration of simulator EEP support, release 18.11.02.521379.

RC Land Impact Calculation Revision

The Land Impact update being deployed to the RC channels is to correct an error in the Animesh code. In short, if an Animesh object has a conventional prim as its root, the required 15 LI for the Animesh skeleton is not applied.

This 15 LI is an aggregate value for Animesh arrived at during testing Animesh performance across a range of systems. It has also been subject to some alarmist blog posts about unexpected prim returns, but given Animesh products are not generally available as yet, this is unlikely.

SL Viewer

There have been no viewer updates from the Lab at the start of the week, leaving the various pipelines as per the end of week #44.

  • Current Release version 5.1.9.519298, dated September 5, promoted September 26. Formerly the Rakomelo Maintenance RC viewer – No change.
  • Release channel cohorts:
    • Spotykach Maintenance RC viewer, version 5.1.10.520686, October 30.
    • Animesh RC viewer, version 6.0.0.520636, October 18.
    • Estate Access Management (EAM) RC viewer, version 5.2.0.520057, September 28.
    • BugSplat RC viewer, version 5.1.9.519462, September 10. This viewer is functionally identical to the current release viewer, but uses BugSplat for crash reporting, rather than the Lab’s own Breakpad based crash reporting tools.
    • Love Me Render RC viewer, version 5.1.8.518751, released on August 20.
  • Project viewers:
  • Linux Spur viewer, version 5.0.9.329906, dated November 17, 2017 and promoted to release status 29 November – offered pending a Linux version of the Alex Ivy viewer code.
  • Obsolete platform viewer, version 3.7.28.300847, May 8, 2015 – provided for users on Windows XP and OS X versions below 10.7.

In Brief

HTTP “throttles”: there have been questions on what any  throttles on incoming / outgoing HTTP communications might be. In reply,  Simon and Oz Linden stated:

We don’t want to block any “reasonable” use of http in with throttles, for whatever that really means. Don’t expect to write anything fast and high-load with http in, however. I’d just generally say “keep it slow”. I think the original idea for http in (and out) was it was going to be web-page speed, not a twitch game.

– Simon Linden

The amount of impact incoming http has can also vary depending on what else is on the system your region(s) are shared with (which you can’t easily determine). We have had times when we have asked users to modify how they use http-in to prevent problems.

– Oz Linden

Key binding: there have often been requests for broader / more configurable options for key binding within the viewer / SL, a subject raised at the meeting, with Oz Linden again commenting:

I have a standing offer to accept a contribution that will provide a complete key binding editor for the viewer.

Scriptable UI: another long-standing request is for a more scriptable UI for SL.  This could help with a range of capabilities – such as the viewer taking over actions that are currently dependent on simulator intervention, which and slow things down. However, viewer-side scripting support brings within it a number of issues – such as the code being unprotected, for example. So, not something liable to happen in the foreseeable future.

2018 SL UG updates 44/1: Weekend issues

Little Havana; Inara Pey, September 2018, on FlickrLittle Havanablog post

Unfortunately, the clock change in the UK / Europe meant I was unable to make the Simulator User Group meeting on Tuesday, October 30th.

Server Deployment Plans

As always, please refer to the server deployment thread for the latest news and updates.

Weekend Issues

Shug Maitland kept an eye on the ups and downs of log-ins during the DDOS attack via https://etitsup.com/slstats/ through Sunday, October 28th, 2018 and into the early hours of Monday, October 29th, sending me this above capture

As most are aware, Sunday saw some significant issues with Second Life, with users in particular have log-in issues.

It appears the problems were directly the result of a prolonged / vicious distributed denial of service (DDOS) attack, as April Linden confirmed in the forums, stating:

Heya Folks.

I can confirm it was a DDoS attack, and yes, the folks on my team had a rough weekend.

We do our best to fight DDoSes, but this one took quite a bit more effort than normal.

I’m sorry people’s plans got interrupted over the weekend. It was a rough weekend for all of us… including those of us on this side of the grid, too.

I’ve no idea if there will be a more formal blog post on the matter or not.

2018 SL UG updates 43/1: Simulator User Group

Ashemi Reprise; Inara Pey, September 2018, August 2018, on FlickrAshemi Repriseblog post

Server Deployment Plans

As always, please refer to the server deployment thread for the latest news and updates.

  • On Tuesday, October 23rd, the SLS (Main) channel updated to server release 18#18.10.04.520268, comprising internal fixes.
  • On Wednesday, October 24th, 2018, the RC channels should be updated as follows:
    • BlueSteel will apparently remain on server maintenance package 18#18.10.04.520268.
    • Magnum and LeTigre were “TBD” at the time of writing.
    • Note that the deployment information for Snack in the thread (version 18.10.19.520844) is incorrect – see below for more (this may be removed after these notes are published).

SL Viewer

The start of week #43 has seen no change to the current viewer pipelines:

  • Current Release version 5.1.9.519298, dated September 5, promoted September 26. Formerly the Rakomelo Maintenance RC viewer – No change.
  • Release channel cohorts (please see my notes on manually installing RC viewer versions if you wish to install any release candidate(s) yourself):
    • Animesh RC viewer, version 6.0.0.520636, October 18.
    • Spotykach Maintenance RC viewer, version 5.1.10.520444, October 11.
    • Estate Access Management (EAM) RC viewer, version 5.2.0.520057, September 28.
    • BugSplat RC viewer, version 5.1.9.519462, September 10. This viewer is functionally identical to the current release viewer, but uses BugSplat for crash reporting, rather than the Lab’s own Breakpad based crash reporting tools.
    • Love Me Render RC viewer, version 5.1.8.518751, released on August 20.
  • Project viewers:
  • Linux Spur viewer, version 5.0.9.329906, dated November 17, 2017 and promoted to release status 29 November – offered pending a Linux version of the Alex Ivy viewer code.
  • Obsolete platform viewer, version 3.7.28.300847, May 8, 2015 – provided for users on Windows XP and OS X versions below 10.7.

Environmental Enhancement Project – EEP

  • The Snack RC channel has been updated with a new EPP release, 18.10.20.520891, which seems to fix the issue of EEP skies looking weird (black skies, fast-moving clouds) when seen on non-EEP viewers.
  • Rider Linden is now working on adding LSL support to EEP.

Aditi Account Set-up Reminder

Given EEP is available for testing on Aditi, a quick reminder on how to log-in to that grid if you have not done so before or in a long while:

  • File a support ticket requesting access to Aditi.
  • Wait for support to confirm your account has been set-up.
  • Log-in to Aditi. This may not give you a full copy of your inventory, however it will flag your inventory for syncing with Agni.
  • Syncing operations are run daily at roughly 02:00 SLT, so if you wait about 24 hours (depending on the time of your initial log-in to Aditi), your inventory on the beta grid should be synced with your Agni inventory.

The EEP testing region is: secondlife://Aditi/secondlife/EEPTesting/247/44/23.

Simulator User Group

Server Deployment Plans

As always, please refer to the server deployment thread for the latest news and updates.

  • There was no deployment to the SLS (Main) channel on Tuesday, October 16th, 2018, leaving the simulators on that channel running on server release 18#18.09.20.519894, comprising the simulator update for Bakes on Mesh. However, regions on the channel were restarted, per the Lab’s 14-day restart policy.
  • On Wednesday, October 17th, 2018, the RC channels should be updated as follows:
    • The three core RC channels, Magnum, LeTigre and BlueSteel should all be updated with server maintenance package 18#18.10.04.520268 containing internal fixes.
    • The Snack RC channel should be updated with server release 18.10.09.520401, containing server-side EEP support. This will be an initially limited deployment to regions under LL’s management.

SL  Viewer

There were two SL viewer updates at the end of week #41:

  • The Environmental Enhancement Project (EEP) project viewer updated to version 5.1.10.520475, on October 12th.
  • the Spotykach Maintenance RC viewer updated to version 5.1.10.520444 on October 11th.

The rest of the official viewers remain unchanged at the start of week #42:

  • Current Release version 5.1.9.519298, dated September 5th, promoted September 26th. Formerly the Rakomelo Maintenance RC viewer – No change.
  • Release channel cohorts (please see my notes on manually installing RC viewer versions if you wish to install any release candidate(s) yourself):
    • Animesh RC viewer, version 6.0.0.520211, October 8th.
    • Estate Access Management (EAM) RC viewer, version 5.2.0.520057, September 28th.
    • BugSplat RC viewer, version 5.1.9.519462, September 10th. This viewer is functionally identical to the current release viewer, but uses BugSplat for crash reporting, rather than the Lab’s own Breakpad based crash reporting tools.
    • Love Me Render RC viewer, version 5.1.8.518751, released on August 20th.
  • Project viewers:
  • Linux Spur viewer, version 5.0.9.329906, dated November 17th, 2017 – offered pending a Linux version of the Alex Ivy viewer code.
  • Obsolete platform viewer, version 3.7.28.300847, May 8th, 2015 – provided for users on Windows XP and OS X versions below 10.7.

Non-HTTP Asset Fetching

For some time now, all SL assets have been fetched using HTTP via the Lab’s CDN provider(s), avoiding the need for the simulator to handle all asset transfers and associated messaging directly. While the viewer code has long had the necessary code to support asset fetching via HTTP / CDN, the code for the old, non-HTTP fetching has remained in place in the simulator, allowing much older viewer versions to continue to fetch assets by way of the simulator.

However, Linden Lab has announced that as from January 6th, 2019, they will be removing the old non-HTTP fetching methods from the simulator code. Any viewers still fetching the affected asset types via UDP after this date will not longer work correctly.

The specific asset types affected by this change are: system body parts, system clothing, gesture, animations, sounds, and landmarks (mesh, textures and avatar appearance having long been HTTP only).

Operating System Update

The Lab is working on another major operating system update for the simulators and their back-end services. Part of this work is being deployed to the Morris region on Aditi, the beta grid, on Tuesday, October 16th, 2018. As OS updates can lead to some unanticipated outcomes, the deployment to Morris is very much a test of the new code. Those who routinely use the beta grid and the Morris region are asked to raise a beta grid Jira on any issues or other “oddness” they note subsequent to the deployment – “oddness” in this case being anything outside of the usual / expected behaviour of things.

The Cloud and “On Demand” Regions

Questions continue to be asked about the use of “on demand” regions following SL’s eventual move to cloud infrastructure. That is, regions that are only spun-up and active when one or more avatars are in them.

As Ebbe and others from the Lab has indicated, making regions “on demand” is not a priority at present with the move. Rather the focus is on shifting SL to the cloud “as is”, without significant changes to how the simulators and their region appear to operate.

While an “on demand” region offering might be possible in the future, it will most likely be an entirely new product offering when compared to the current Full and Homestead region types, and would probably only by suited to a standalone use, rather than such regions being part of any contiguous land mass, simply because of the complexities of  access (imagine trying to fly across multiple regions and having to stop at each border for 60+ seconds while the next region is deployed and spun-up) and in handling LSL scripts that assume all regions are running all the time, etc.

So , don’t expect anything like these immediately after the move – although such a product might surface at some point in the future, one the Lab have built up confidence in running SL in the cloud.

In Brief

  • BUG-216320 “Error when retrieving grid statistics page via llHTTPRequest”: no fix as yet.
  • BUG-7084 “Prim properties visually revert to an earlier state since Interesting”: again, no progress to report at present.
EEP is coming! server-side support is being deployed in week #42 on a limited basis to the main grid (Snack RC), and Simon Linden has been having seasonal fun with his home parcel. Expect EEP to gain wider simulator availability in the coming weeks. Credit: Simon Linden

Server Deployments

As always, please refer to the server deployment thread for updates.

  • There was no deployment to the SLS (Main) channel on Tuesday, October 9th, 2018. This remains on server release 18#18.09.20.519894.
  • At the time of writing, no deployment to the three RC channels are listed for Wednesday, October 10th, leaving them on server release 18#18.09.24.519940. However, during the meeting, Simon suggested a deployment might be made.

SL Viewer

The Animesh RC viewer updated to version 6.0.0.520211 on Tuesday, October 8th. This update includes the following updates / changes:

  • SL-966 scale and position offset limits are now enforced for Animesh objects. The current scale limit is 64m, offset remains at 3m
  • SL-1290 Issue with animations not rendering if they were stopped and started while host object is selected.
  • SL-9673 some HUDs collapse to low LOD when zooming.
  • SL-1350 Animesh angle offset lags when linked to rotating prim
  • SL-9773 attached Animesh objects visible in mouselook when “show me in mouselook” is unchecked.
  • SL-1291 Animesh selection highlights not showing in edit mode.

Note it does not contain fixes related to the performance loss issue reported in BUG-225584, and noted in my previous TPD meeting summary.

The remaining viewers in the pipeline remain unchanged from the end of week #40:

  • Current Release version 5.1.9.519298, dated September 5, promoted September 26. Formerly the Rakomelo Maintenance RC viewer – No change.
  • Release channel cohorts (please see my notes on manually installing RC viewer versions if you wish to install any release candidate(s) yourself):
    • Spotykach Maintenance RC viewer, version 5.1.10.520176, October 4.
    • Estate Access Management (EAM) RC viewer, version 5.2.0.520057, September 28.
    • BugSplat RC viewer, version 5.1.9.519462, September 10. This viewer is functionally identical to the current release viewer, but uses BugSplat for crash reporting, rather than the Lab’s own Breakpad based crash reporting tools.
    • Love Me Render RC viewer, version 5.1.8.518751, released on August 20.
  • Project viewers:
  • Linux Spur viewer, version 5.0.9.329906, dated November 17, 2017 and promoted to release status 29 November – offered pending a Linux version of the Alex Ivy viewer code.
  • Obsolete platform viewer, version 3.7.28.300847, May 8, 2015 – provided for users on Windows XP and OS X versions below 10.7.

In Brief

  • Region Crossings: see BUG-214653. In brief, several issues are related to message handling between server(s) and viewer. Assorted solutions have been suggested, with Simon linden noting, “Yeah at some point we may want to totally re-do that sequence of messages and get rid of all UDP traffic. It would probably be a little slower but having a more solid sequence would be better.”
  • BUG-216320 “Error when retrieving grid statistics page via llHTTPRequest”: this has been an issue since May, 2018, it had been hoped that the OS update would fix it, but currently there is still one component that needs to be updated in order to fix the issue.
  • The anticipated end date for the simulator OS update, which is key to the work in moving things to the cloud, is the end of 2018 or early 2019. After which there are the back-end services to update.

2018 SL UG updates 40/1: Simulator and Governance

[Eclectica] A New Dawn; Inara Pey, August 2018, on Flickr[Eclectica] A New Dawnblog post

Simulator User Group

Not a lot to report this week; some discussion on documenting throttles on various LSL requests (i.e. updating wiki entries to indicate those functions that have throttles, rather than providing specific throttle information), and the inevitable region crossing chatter.

Server Deployment Plans

  • On Tuesday, October 2nd, the SLS (Main) channel was updated with server maintenance package 18#18.09.20.519894, comprising the simulator update for Bakes on Mesh.
    • I believe this update still requires a Bake Service update (support for 1024×1024 textures).
  • On Wednesday, October 3rd, the three main RC channels should all be updates with service maintenance package 18#18.09.24.519940, comprising internal fixes.

SL Viewer

The following two viewers were updated on Friday, September 28th:

At the start of week #40, all other viewers remain as follows:

  • Current Release version 5.1.9.519298, dated September 5, promoted September 26. Formerly the Rakomelo Maintenance RC viewer – NEW.
  • Release channel cohorts:
    • BugSplat RC viewer, version 5.1.9.519462, September 10. This viewer is functionally identical to the current release viewer, but uses BugSplat for crash reporting, rather than the Lab’s own Breakpad based crash reporting tools.
    • Animesh RC viewer, version 6.0.0.518949, August 24.
    • Love Me Render RC viewer, version 5.1.8.518751, released on August 20.
  • Project viewers:
  • Linux Spur viewer, version 5.0.9.329906, dated November 17, 2017 and promoted to release status 29 November – offered pending a Linux version of the Alex Ivy viewer code.
  • Obsolete platform viewer, version 3.7.28.300847, May 8, 2015 – provided for users on Windows XP and OS X versions below 10.7. This viewer will remain available for as long as reasonable, but will not be updated with new features or bug fixes.

Governance User Group

Governance User Group (GUG) meetings are generally held on alternate Tuesdays at 13:00 SLT. They are intended to provide a forum for the discussion and education of issues involving Governance.  They are chaired by the GTeam supervisor, Kristen Linden and are open to the public. Details on dates, times and location can be found on the Governance User Group wiki page.

The Governance Team is responsible for dealing with Abuse Reports, in-world abuse, forum reports, Marketplace reports, etc. It is not responsible for issues with accounts being compromised, account subscription delinquency, fraud, IP infringement, etc.

  • These matters cannot be discussed at the GUG meetings.
  • Issues relating to them should be reported through the recommended channels (e.g. Support for account-specific issues, via the DMCA process for IP infringements, content theft, etc).

Similarly, individual cases involving Governance issues (e.g. the outcomes of abuse report filings), cannot be publicly discussed.

Resources

Meeting CliffsNotesTM

  • General comment on L$ reclaims: somewhat related to fraud, despite notes above. If someone receives L$ amounts as a result of fraud or similar issues, when those amounts are reclaimed via the Lab, they will show up as a transaction record in the user’s account transaction history.
  • Visitor trackers – are these a violation? the Governance Team is aware they exists, and generally do not action reports relating to them (radar systems report more-or-less the same information, available from the mini-map).
    • Similarly, the Governance Team tends not to get involved with tar jars that record tippers names / amounts. The suggestion for those who do not wish to have their name recorded when tipping is to tip directly, avatar-to-avatar.
  • Warnings / Suspensions / Termination: Tommy Linden pointed out that the reason someone is receiving a warning or a notice of suspension / termination will receive “a specific reason” on why the action is being taken in the e-mail notifying them of the warning / suspension.
  • Bans and Termination: the Governance Team only ban / terminate as a result of in-world issues related to platform governance. However, users can be banned / terminated by other LL teams (e.g. fraud, legal / IP), depending on the nature of the infraction / activity.
  • Can SL users be banned for things placed on external blogs, etc? As far as the Governance Team is concerned – no.  It is recognised that the team have no jurisdiction over mediums and services outside of those owned by Linden Lab.
    • Users who believe their personal data is being incorrectly publicised via the likes of blogs, etc., on other services, or believe they are being defamed, are advised to go through the complaints process native to the platform in question, and not file an Abuse Report with the Lab.
    • Issues the Lab have with external services, websites, etc., that are felt to be violating things like the company’s brand usage, trademarks, or which might be seen as defamatory, are dealt with by the legal department.
  • Personal questions: asking personal questions – even repeatedly – is not actionable as an AR. No-one has to answer questions, and other avatars can be muted / block if they persist. However, if someone does repeatedly harass a user with personal questions, etc., even beyond blocking, the an AR for harassment can be raised.
  • 24/7 coverage: the Governance Team is “not totally” active on a 24/7, but are deliberately unpredictable in hours kept so that times when Governance may not be available can be easily calculated by potential troublemakers.
  • Does the GTeam track those banned from regions / parcels? No. The region / parcel capability is there for region / parcel holders to use. However, ARs can be a means to identify serial griefers.
  • Does the simulator save a copy of the simstate when an AR is filed? No, however, the logs, etc are available for review during an investigation  – providing the AR is filed within a reasonable time of the incident occurring.
  • Should specific sections of the TOS / Community Standards be quoted in an AR: they can be, but it is not a requirement. A clear description of the incident, with all relevant information and an accurate AR category filing is far better.
  • ARs against copybotting, IP infringement: these are not investigated, but attempts are made to educate on how to file a DMCA.
  • Nudity on Moderate regions: generally considered OK, but nudity with sexual connotations (e.g. sexual acts or a naked male avatar with an erection, in public places) can be AR’d.
    • Region / parcel holders are free to specify no nudity and / or no sexual acts on their regions, regardless as to the rating.

Next Meeting

Subject to confirmation on the Governance User Group wiki page, the next meeting should be on Tuesday, October 16th, 2018. However, the location may change.
