Quote from DarkKostas :No more waitings for players to connect, so we can pit/spec/leave server(and even join server without waiting others now!)

Well, this is quite interesting - what you suggest is partly true and partly not.

Yes, you will be able to leave the server without waiting while someone is connecting. This was a real problem in the past but now it should be fine, because the host can continue processing without your packets.

Pit / Spectate / Join - in the first version you will still have to wait while a guest is connecting (to preserve the game state that is being sent to the new player and avoid a Join Out Of Sync) but I'm hoping this will be less annoying already, because the connecting guest will be a bit quicker. His connection should take less time because he doesn't need to wait for a first packet from everyone else connected to the host.

The new systen does allow a possibility of taking away that wait completely, with some work on the way a guest connects. But that isn't really easy so I'd prefer to get the new thing tested. Then we can reassess what are the highest priorities at that point. I do want to get back to the tyre physics but we'll just see what comes up during the patch testing.
Test Patch (with same old physics) Coming Soon [Now]

Hello LFS Racers,

A lot of you already know, but many don't, because the information is buried deep inside a thread about a hacker.

In the next few days we'll be able to release a test patch with multiplayer improvements. It's not one that uses the new tyre physics which is still being developed, and does not contain any new content. I had to start working on this because hackers found a way to join a host as an administrator using a false user name, such as a single space. They could then use various cheats and could not be kicked or banned from the host. A dedicated host update 0.6B4 solved this particular problem but one of the hackers demonstrated that he was still able to cause a host to crash. Luckily, this time I was able to work out the probable cause and implement a fix. Just before that, I was already trying out a test of a new way for the multiplayer system to work - instead of waiting for messages from all guests, the system now only waits for messages from the host. So if there is one laggy connection, or someone lags temporarily, it won't have a negative effect on other people (other than seeing a lagging car).

Main improvements due to the new system :

Physics and all replays are still compatible
Game only needs host packets to continue processing
Quicker joining to host - no waiting for other players
No waiting for packets from players with slow connections
Much longer timeouts - lower probability of disconnection

Also there are fixes for various bugs and security issues that have been reported, and some more improvements that I can do because of the new multiplayer system.

EDIT : Test Patch 0.6B7 is now available for testing : http://www.lfsforum.net/showthread.php?t=80725

Incompatible Patch

About the incompatible update, the main thing about it is an improved multiplayer system that will make the host more responsive and reliable.

I see from the crash address there is some kind of memory corruption taking place, perhaps a buffer overrun. I'll have to analyse the code very carefully to see what's happening, as I have no reason to think that the new incompatible improvements have changed that.

It would be really helpful if krup or AnakinSkywalker would let us know how they got in as an admin and how they could crash the host. It would take them a few minutes to send us the explanation, which packets they send to exploit the vulnerability. It would mean I could make LFS safe again and we could move on, and I could release the more responsive and reliable version that I have here and intended to release today. There is no development on the tyre physics while there is a security risk in LFS. I remember when Luigi Auriemma found vulnerabilities, he told us about how it was done, and that was great.

No, it's really complicated.

I'm interested in the support for Arabic and Hebrew but it's a big job and it has lower priority than the new tyre physics and S3.

On topic :

I hope to release a dedicated host test update either today or tomorrow, that should at least prevent the user being connected with a user name you cannot type, or a user name that does not match the user id.

Off topic :

Although development has been slow for some time, we are still motivated on LFS, which we do regard as a long term thing. I must admit this year both Eric and I have had some slow months and some months in which we didn't do much LFS at all.

In both our cases that has been partly for external reasons which will not have a long term negative effect, and also partly a need for a slight break after several years of hard work.

In my case I have got into some sport (cross country running and cycling) which has obvious benefits I don't need to explain, after two decades without. That occupied my mind a lot (in a good way) and has been great for me and my family, but not great in an immediate sense for LFS's development this summer. The journey of tyre physics development has been a tough one, round and round, forwards and backwards these couple of years. I feel this summer break has helped me mentally. I've got some answers and plan to get that tyre stuff sorted out so we can get back to the fun stuff and a faster development rate in the S3 period.
Progress Report December 2011
Scawen
Developer
A short progress report posted on www.lfs.net :

Dear LFS Racers,

We hope you had a good year in 2011. In June we released 0.6B, the best version of LFS so far. Since then we have been continuing to work towards the new tyre model and the S3 upgrade which we plan to release after the physics update.

Scawen has been further developing the virtual tyre test rig, a detailed model of a tyre's structure, to work out various values for the in-game tyre model. For example, what is the contact patch length, width and pressure for a given vertical deflection and how does the tyre's shape change with forces, torques and camber. These depend on the dimensions and structure of a tyre. By making the in-game tyres behave in a similar way, the driving experience will be as realistic as possible.

In the left part of the image, the yellow lines show the radial cords of the carcass. The orange and green lines show the steel belts and the cap ply. The right side of the image illustrates the carcass thickness which gives some rigidity even without air pressure.

Eric has been working on the S3 content. After the physics update and the VW Scirocco are released as a free update for all S1 and S2 license holders, we will work towards the S3 update which will provide more tracks and cars to S3 license holders. As usual for an upgrade, the cost of your existing license will be deducted from the full price.

We wish you a happy 2012, and we'll release the updates as soon as we can!

Hello Racers,

We expect to release a new official version this week. It does not contain the new tyre physics / VW Scirocco / Rockingham. But it's a good LFS update for you to use while the new tyre physics system is finished.

The main things in the new patch :

- New free view in SHIFT+U mode - not bounded by the path
- Improved collision system (with objects / cars / pit garage exit)
- Maximum placed autocross objects increased to 800 (was 512)
- New autocross objects and all objects available at all tracks
- Open track configurations allowing you to drive anywhere
- Collision detection and reporting system (via InSim)
- Graphical optimisations improving frame rates
- Adjustable tyre warmers for hot lapping
- Many other fixes and improvements


It has been tested by the community for some time now. If you haven't tried it yet, you can follow the link below to try out the latest 0.6A version. But please note : if you install the test patch in your existing folder, you can no longer join the Z28 hosts. There are plenty of 0.6A hosts to join if you'd like to do some racing in the new version.

In the tyre physics update which is in development, tyre warmers are banned in most classes. They will only be allowed in F1 and GTR classes if I remember correctly. Making that change in the current tyre physics would probably be unsuitable - grip levels in the other classes might be unrealistically low at the start of races. So, making that full change now wouldn't be a good idea.

However, tyre warmers will still be allowed in Hot Lapping mode even with the new physics, so it was a good idea to do that now, so eliminating some of the tyre warming procedure that people went through before a hot lap, which was kind of a problem.

But that problem didn't really exist in races - no-one is going to start doing donuts for half a hour as soon as the red light go out. So there wasn't any real problem to be solved in the case of racing, and we decided to just leave that as it is.

Quote from Luke.S :The speed bumps together like that seem to give the cars a huge speed boost. Got a UF1 well above 100mph by driving over them back towards the starting area.

That is a known problem, and it is due to a sampling error (your tyres do not test all positions between one physics update and the next). I've tested it a lot today, you can even get the acceleration if you go into neutral before hitting the bumps. I don't know if this anomaly can be fixed (or improved) or not, but it doesn't really come up in normal situations so it's not *that* important. It's not actually a new problem, it's just that the new speed humps can show up this flaw.

Yes, we agree 100%. The hotlap tables will not be reset, because there isn't a significant change in physics. The new exe has the old collision code in it and the ability to avoid converting objects to the new object system so that it can use that when it runs old replays, so they don't go OOS.

However, as the rules have changed a bit, some hotlaps will be deleted (and an email will be sent to their owner).

The hotlaps that will be deleted nearly all fit into these two categories :

1) Hotlaps with a pit stop
2) Hotlaps (mostly at SO) with a wall hit that was undetected by the old HLVC wall hit check

Number (2) will affect quite a lot of hotlaps. For example, about 55 South City world record hotlaps will be deleted because of this.

EDIT : Please hotlappers do try out the 0.6A1 hotlapping system. Victor and I worked for quite a while to try and make sure the wall hit detection was "fair". That means - invalidating hotlaps if the hit was significant, but trying not to invalidate them when there is a small scrape that wouldn't really benefit the lap time. Clearly there's a slight grey area but we had to draw the line somewhere.

When we will release an official patch with changes in physics, there will be a series of test patches before the official release, also with changes in physics.

That's how we've done it for years now, we release test patches before the final release. This way, we know that the final release has a good chance of being stable and bug free.

What we don't do is release dozens of test patches, then release something completely different. Because that wouldn't really make much sense.

Quote from insaneltu :But in next version's it will be changed?

I don't know, I don't have the future planned out in that kind of detail.

There are different ways of detecting collisions, avoiding intersections before the collision is detected. I'd like to look into that some time, but I don't know when, because it is a big project in itself. Not something to do in the last week before an official patch.

I'm quite happy with the recent collision detection improvements for now, so further development of that is way down the list, compared with finishing the new tyre physics.

The plan is to fix the remaining bugs and release the official patch within a week. Whether that will happen or not I obviously can't say 100% but that is definitely the plan.

Quote from avetere :So we finally got a new mpr-version (15).
Was that only to prevent lfs 0.5 to play the new ones or was anything else altered? (Though I'd appreciate details a simple yes/no would be sufficient for the moment )

Edit: As a reminder: How about the width of autocross-objects? Where you able to get them? (No hurrying though )

The replay version is mainly so that LFS knows if autocross objects in the replay refer to old numbers (track is then not converted) or new numbers (track is converted as usual).

No, I haven't yet had anything like enough spare time to generate an object size data file.

Quote from [Audi TT] :Scawen, and when can be downloaded hotlaps? I am one hotlap made ​​with the improvement of the time, but you can not download ((

When the patch is official. It would be a very bad idea to accept replays from test patches for more than one reason.

1) The majority of people are not using test patches, so they could not watch the replay.
2) The physics changed several times during the test patch period. Most are obsolete and will never be viewable again.

A test patch is just for testing, not for entering the hotlap competition.

Quote from kimd41 :Okay, I wanted to install this patch on a fresh install, so I downloaded the full Z28 from LFS.NET and installed. Then I installed this patch.

Now, after the driver creation screen, it shows the Agreement screen and when I click "agree" it crashes. Every time.

Thank you. I can reproduce this by setting "Welcome Z 1" in cfg.txt - so I don't need any more information.

Maybe you can get round it for now by adding a line in your cfg.txt :

Welcome Z 0 so it doesn't run the welcome sequence.

pik_d :

The problem is that if people have do do all sorts of crazy things to be competitive, then you can't be competitive without doing those crazy things.

So for example if it takes half an hour and several pit stops to get the car into a state where you can get a world record, then this is quite a problem. We don't want people to have to do that. This is about getting in your car and doing a fast lap. Ideally that's what it would be. The hotlap tables are supposed to show who can drive the fastest lap, not who is patient enough to exploit flaws in the physics system that can be exploited in a one hour replay.

Victor's point about not limiting the time is that really, LFS physics should be realistic enough that a car should be best when it is fresh, warmed up but not worn out. At the moment, LFS physics isn't quite producing this outcome. But we hope that in future it will.

No... tyre warmers in racing are changing with the new tyre physics (most classes don't have tyre warmers any more). I don't know if we'll have adjustable ones in the future but I don't want to get into that now, implementing it into multiplayer packets to pass the information around and so on, it would take more time.

Anyway, the same problem doesn't exist in racing - people don't start doing donuts and all manner of crazy looking things to warm up their tyres before they start going round the track.

OK, I've done the slider bar, you can choose between 20 and zero below optimum.

Yes, it is a good idea to do this now, the same will apply to the new tyre physics so it's not a waste of time, and this is the layouts patch.

It's nearly finished, I just need to break HLVC when any added object is touched (not just the movable ones).

Quote from Scawen :...in the Z30 to Z34 versions, the ramps at South City had too high an index that cannot be supported by the Z35 code. So all it means is that Z30 to Z34 replays with ramps in them will have no ramps if played in Z35.

Correction to this information...

The story with the ramps is :

- Ramp1 and Ramp2, like all autocross objects, will be available at all tracks.

- However... old test patch replays (Z30 to Z34) that contained Ramp1 or Ramp2 (at any track, not just South City) will not contain the ramps when played back in Z35. Other than that, test patch replays and old replays still do play back, except single player replays that were recorded on one of the intermediate physics versions, and a very small minority of old hotlap replays.

That's not a big deal at all in my opinion. I'm just correcting my previous statement that said this "problem" would only be at South City.

Progress :

The unified autocross objects system and the code that loads old layouts is all completed (except for a couple of remaining notes on my sheet) and working well. But I'm a day or two later than expected with that and as there are quite a few things on my "incompatible patch" list of things to do, plus some new bug reports, I can see that this will not be ready for release on Friday. But it's going well and will be a good patch when it's released, which I now expect to be next week.

Well it's very simple.

Z35 guests will not be able to connect to pre-Z35 hosts.
Pre-Z35 guests will not be able to connect to Z35 hosts.

Pre-Z35 will not be able watch replays recorded in Z35.
Z35 will be able to watch replays recorded in pre-Z35.

It's just an incompatible version like any other, but without breaking old replays.
I didn't think it needed such a detailed explanation!

DISCLAIMER : It's possible there may be some cases of old replays that cannot be viewed. One I can think of is that pre-Z35 replays recorded at South City that included Ramp1 or Ramp2 will not work, because they had a very high object index that is now out of range and cannot be supported by the new code. It's also possible that a few old hotlap replays might go OOS, though I have tried very hard never to break them, and to run a check on the world record replays every couple of days, it is still possible that a few Z28 hotlaps will not play, with so many changes in the code (although LFS is specifically coded to use the old contact detection system just when watching old single player replays). Also single player replays recorded after Z28 and before Z35 are extremely likely to go out of sync, because there were a few physics changes during that time.

I hope that is detailed enough so I can go back to work now.

Here is a link to my actual progress report which I think is more interesting in case anyone missed it :

Quote from avih :Is this patch going to be promoted as an official update eventually? If yes, would that be smart to break backward compatibility for reasons other than a physics update or meaningful tracks updates?

Yes, the purpose of a run of test patches is to release an official patch without bugs. The breaking of multiplayer compatibility is not a problem in that case - people should just click "yes" when asked if they want to update their version. But I have been very careful not to break the hotlaps - most old hotlaps and other replays can still be played back in the new version.

I agree, I would not like to delete all the hotlap tables until the real new tyre physics or actual new tracks are released.

But it is quite impossible to retain multiplayer compatibility when there are new autocross objects and they have different numbers and you can drive on open configurations. This latest one breaks multiplayer backward compatibility too because of the qualifying and red lights changes and the object numbers. But that's why I've saved that until last, so the community is divided for the smallest possible time. I want the official version out as fast as possible after the incompatible test patch.
