03:32 OldCoder <OldCoder> minetest.org is being DDoSed right now, Perrtu. I am the target. No other machine in the host's network is presently under attack.
03:32 OldCoder <OldCoder> Tell the trolls to consider their actions carefully.
03:32 OldCoder <OldCoder> There are 117,000 sessions. This is the work of somebody in power; one of the core devs or their friends.
03:33 OldCoder nore, sofar, shivajiva, others; my host has good hardware. And I do prosecute.
03:33 OldCoder I've been through this before in other contexts.
03:34 sofar everyone, please do not respond
03:34 sofar I advise you to not reply to oldcoder in any way on these accusations
03:34 OldCoder sofar, I'll hire an attorney and subpoena
03:34 OldCoder RedHat
03:35 OldCoder based on your involvement. Think it's a bluff?
03:35 OldCoder They are not "accusations". Wish to speak with my host right now?
03:35 sofar I always take legal accusations seriously
03:35 OldCoder You should
03:35 Zeno` Why would a core dev have that many shells?
03:35 OldCoder And I am being DDoSed
03:35 sofar Zeno`: please, do not respond
03:35 OldCoder hang on, I'm getting more details
03:35 OldCoder sofar, hush
03:36 OldCoder sofar, justify your remarks if you are not involved
03:36 OldCoder But excuse me, host is updating his own scans
03:36 OldCoder We may be able to trace the network if it is not HMA
03:36 OldCoder This (a) is childish (b) will not hurt me (c) is attracting my attention
03:37 octacian #5627
03:37 ShadowBot https://github.com/minetest/minetest/issues/5627 -- Menu: Merge singleplayer and server tabs by octacian
03:37 sofar OldCoder: I have no obligation to justify any remarks
03:38 OldCoder It was a sensible point. And here is a sensible link for you to review:
03:38 OldCoder Moment, host is vetting it
03:39 OldCoder Host offers correction. It is 17,000, not 117,000. That is a lot of simultaneous connections, though.
03:40 OldCoder Fortunately, I am not hosting from a living room floor. My host is the equal of anybody you know. Anyway, here is the link:
03:40 OldCoder http://minetest.org/geethanks.txt
03:40 behalebabo joined #minetest-dev
03:40 OldCoder Are those IPV4s known to anybody present? Perhaps they are RedHat IPV4s, sofar ?
03:41 OldCoder Note that 1,000s of connections are originating *simultaneously* from each of them
03:41 sofar https://www.maxmind.com/en/geoip-demo try it
03:41 Hijiri does redhat mean something other than the distro
03:41 OldCoder I had not really noticed, sorry about that, it is like a sneeze. I know how...
03:41 OldCoder Hijiri, the company
03:41 OldCoder sofar, I do know how to geolocate
03:41 Hijiri oh yeah
03:41 sofar I don't think redhat has AT&T U-Verse blocks
03:41 OldCoder I have been fighting DDoSers in my family for 4 years... My brother is the VP of Lab126 and uses Amazon for this purpose.
03:42 OldCoder sofar, I knew it wasn't you. I found your remarks to be out of line.
03:42 sofar obviously whoever is doing this is using a botnet
03:42 OldCoder AT&T is a surprise, though...
03:42 OldCoder Well, yes
03:42 OldCoder So, I won't be able to track the IPV4s
03:42 OldCoder But the originators will recognize them, correct?
03:42 OldCoder U-Verse is residential. I'd expected this to be Russia.
03:43 OldCoder Talking to host about that, excuse me...
03:43 sofar maybe someone has backdoored the minebest engine...
03:43 OldCoder No
03:43 OldCoder It was a "booter" server
03:43 OldCoder It was a "booter" service * Observe this:
03:43 OldCoder http://i.imgur.com/QvLWoJN.png
03:44 OldCoder A senior Minetester paid for 4 hours
03:44 OldCoder A 4-hour botnet slot
03:44 OldCoder My host is very, very good
03:44 OldCoder But he won't be able to identify the individual
03:44 OldCoder I'll offer concluding comments shortly, talking to him again
03:44 * OldCoder didn't know that these things came in specific timeslots
03:46 OldCoder Host is digging into this a bit. sofar, do you still wish to use the word "accusations" as though it was nonsense?
03:46 OldCoder Or to contest that somebody here, or who will be here tomorrow, did not purchase this?
03:47 OldCoder Somebody is PM-g #minetest-project'ers and telling them that the channel is "shutting down"
03:47 OldCoder And somebody has purchased a 4-hour professional botnet. Just as a gift for the Old Coder.
03:47 OldCoder How sweet.
03:47 Hijiri I didn't receive any PM
03:47 OldCoder I am in fact kind. I have in fact spent 5 years trying to help here - and succeeding.
03:47 OldCoder Hijiri, sorry
03:48 sofar OldCoder: I'm seeing you make accusations with legal ramifications
03:48 OldCoder I'll try not to speak in absolutes. Somebody is PM'g #minetest-project'ers - one at a time
03:48 OldCoder Not en masse
03:48 OldCoder And somebody has hired a botnet just for me.
03:48 OldCoder sofar, yes; and, respectfully, what is your point? Do you deny the accusations on the part of the core devs?
03:48 OldCoder You are no child
03:49 OldCoder This is no sandbox game
03:49 sofar it appears someone is DDossing you, this I can conclude as well, permitted any of the information you provided in here is accurate
03:49 OldCoder Do you contend, or even believe, that minetest.org is not the specific target?
03:49 sofar this is largely offtopic for this channel
03:50 OldCoder ...
03:50 OldCoder It is not unless you contend
03:50 OldCoder this did not originate right here
03:50 OldCoder Do you so contend? That *will* place it in your responsibility
03:50 OldCoder And *will* offer legal openings
03:51 OldCoder Host says DDoS is restarting
03:51 Hijiri well it's not directly related to development at least
03:51 OldCoder Excuse me briefly, checking details
03:51 OldCoder Hijiri, it is directed at me personally
03:51 OldCoder By this group
03:51 OldCoder I may need to respond
03:51 sofar you go and make your accusations if you so desire
03:52 OldCoder sofar, thank you for your civility
03:52 OldCoder Excuse me briefly, checking details
03:52 OldCoder sofar, just out of curiosity, do you offer an alternative explanation?
03:52 OldCoder Taking into account
03:52 OldCoder That somebody here has asked people
03:52 OldCoder To PM people in -project to the effect that -project is "shutting down" (exact quote) ?
03:52 OldCoder I will have the name of THAT person
03:52 OldCoder in 24 to 48 hours.
03:53 sofar you're misrepresenting statements by people, regularly
03:53 OldCoder Odd, that such PMs would be made even as a DDoS is going on, no?
03:53 OldCoder Indicate misrepresentation, please
03:53 sofar I don't have to
03:54 OldCoder Then withhold your assessment
03:54 OldCoder It is unreasonable to make it and to decline to discuss it
03:54 OldCoder My host is assessing router load
03:54 OldCoder If it is going to cost him anything significant, legal actions will be unavoidable
03:55 OldCoder Other actions as well
03:55 OldCoder It is suggested, politely, that those who are proceeding in this matter
03:55 OldCoder Be advised of the preceding points
03:55 OldCoder sofar, is anything that was just said unreasonable?
03:55 sofar yes, you're threatening people with legal action
03:55 sofar this is immature
03:56 sofar unethical as well
03:56 OldCoder Immature? This may cost my host cash and is a felony violation of CFAA
03:56 sofar I understand you are upset
03:56 OldCoder Hardly
03:56 OldCoder I am starting
03:56 OldCoder to pay attention
03:56 OldCoder Respectfully, people most likely
03:56 OldCoder do not wish my full attention
03:56 sofar but your tone and attitude are unreasonable and outside of the guidelines that have been set out for this channel
03:56 OldCoder Justify your remarks, including that point
03:56 sofar take your legal accusations elsewhere
03:56 sofar please leave this channel
03:56 OldCoder Kick me and I contact RedHat tomorrow
03:56 OldCoder Go ahead. I promise.
03:57 sofar you are mature enough to remove yourself
03:57 OldCoder I am being attacked right now. And my host is a friend.
03:57 OldCoder Excuse me while I check the resource load with him.
03:57 OldCoder sofar, I will phone senior RedHat people at home if you involve yourself.
03:57 OldCoder And provide
03:57 OldCoder Information you may not be aware that I possess
03:57 OldCoder My friend needs me
03:58 OldCoder Excuse me a moment
03:59 OldCoder Waiting on his analysis. sofar, DDoS is a felony violation of CFAA. CFAA has teeth if one knows how to call the teeth.
03:59 OldCoder Do not threaten *me*
03:59 sofar I have made no threats of any form.
04:00 OldCoder You were preparing the framework to state that I was out of line to be present in this channel
04:00 OldCoder This channel that is involved in one of the more prosecutable felonies
04:00 OldCoder In the tech arena
04:00 sofar your current behavior is neither conductive to the project nor friendly
04:01 sofar it is by all means unwanted
04:01 OldCoder I am being DDoSed. By these people. Did I happen to mention that?
04:01 OldCoder That is by all means "unwanted"
04:01 OldCoder Respond to that, politely, or back off
04:01 sofar your complaining and threats of legal action are not in any way a benefit to the community nor do they help the project in any way or form
04:01 OldCoder sofar, does the DDoS do so?
04:01 OldCoder Hm. That almost rhymes.
04:01 OldCoder Repond to that simple question.
04:02 OldCoder Your statement is a non-sequitur, additionally.
04:02 OldCoder If the project commits a prosecutable felony
04:02 OldCoder You are hardly in a position to make the statement that you just did
04:02 OldCoder This is not a kid with a neighborhood botnet
04:02 OldCoder Somebody is putting effort into it
04:03 OldCoder Don't talk to me about "threats" when "threats" have escalated to somebody hurting my host
04:04 sofar again, you are misrepresenting peoples statements left and right, making legal threats, and generally being enormously disruptive to the project and community.
04:05 sofar please, just leave.
04:05 sofar nobody could do more harm to the project than you are currently doing.
04:06 sofar oldcoder, you had a great run. You poored your heart into the project for 5 years
04:06 sofar more than anyone else I think
04:06 OldCoder poured *
04:06 OldCoder sofar, moment, host is assessing
04:06 OldCoder You can be that reasonable
04:07 sofar today is the day you have the opportunity to reassess your commitment and change
04:07 sofar or, you can continue to do what you're attempting to do this very night, and continue the damage
04:07 OldCoder But the point about "legal threats" is bizarre. Um, a felony is being committed and you don't consider consequences...
04:07 OldCoder Stop that. Now.
04:07 OldCoder You will not hold me responsible for the actions of others.
04:07 OldCoder I'll never go there again.
04:07 OldCoder Take responsibility for your own choices.
04:08 OldCoder I've done naught but help, be kind, and stand up to bullies and trolls.
04:08 OldCoder Speaking of which, do hold the part about how I should not talk about calling the police...
04:08 OldCoder until I find out the status of what there is to call about
04:08 OldCoder Minute
04:08 sofar I can not and will not prevent you from calling any authority
04:08 OldCoder Yet you continue
04:08 OldCoder to position the fact
04:08 sofar I'm asking you to leave this channel
04:08 OldCoder that that is the right thing to do
04:09 OldCoder And I am telling you a felony has been committed
04:09 OldCoder And that if you or any identifiable person
04:09 * VanessaE peeks in
04:09 OldCoder Kicks me... I will file a police report
04:09 VanessaE OC, take it to another channel NOW.
04:09 VanessaE this is NOT the place for this discussion
04:09 OldCoder VanessaE, I am being DDoSed. Kick me and I file against sofar at RedHat.
04:09 OldCoder Wait, the DDoS may be ending
04:09 VanessaE I don't have the authority to kick you but I DO have the authority to bitch you out
04:09 OldCoder Will you excuse me long enough to check?
04:09 VanessaE OFFTOPIC, LEAVE.
04:10 OldCoder It is not offtopic. Justify the point.
04:10 OldCoder But let me check the status of my host's hardware first, please
04:10 OldCoder Or is that too civil a request?
04:10 VanessaE this is for core discussion of Minetest engine code and game code, not legal threads over a DDoS that isn't even coming from any of us
04:10 VanessaE no I will NOT wait, take it out of this channel immediately.
04:10 OldCoder VanessaE, that is two parts. #1 is defensible. Justify #2. You know it is one of the people here.
04:10 ShadowBot https://github.com/minetest/minetest/issues/1 -- GlowStone code by anonymousAwesome
04:10 ShadowBot https://github.com/minetest/minetest/issues/2 -- Burned wood
04:11 rdococ . o O ( wtf is going on? )
04:11 OldCoder I have been put through enough
04:11 VanessaE I justify item 2 because even if it WERE someone here, this is still not the place to discuss it.
04:11 OldCoder rdococ, I'm being DDoSed by one of the core devs or their friends
04:11 OldCoder That is point #1 and a point worth considering, VanessaE
04:11 ShadowBot https://github.com/minetest/minetest/issues/1 -- GlowStone code by anonymousAwesome
04:11 OldCoder Regarding point #2, you know they are right here
04:11 ShadowBot https://github.com/minetest/minetest/issues/2 -- Burned wood
04:11 rdococ OldCoder, are you sure it was by someone on here?
04:11 sofar everyone, please do not respond to oldcoder. We've asked him to leave and take it elsewhere
04:11 OldCoder sofar, go one way or the other
04:12 OldCoder rdococ, fair point, I'll discuss that with you in PM
04:12 * OldCoder goes to talk to host friend
04:12 VanessaE OldCoder: I know nothing at all about who is or is not the source of your DDoS, other than I know I've no connection with it because I've been fecking asleep for the past 2 hours, and afk for a few hours before that.
04:12 OldCoder I sleep a lot too, Vanessa
04:12 OldCoder What is your point?
04:13 sofar OldCoder: please leave the channel
04:13 OldCoder Do you have any idea what all of this has cost me financially?
04:13 VanessaE no specific point, just making it clear
04:13 OldCoder sofar, you have made statements
04:13 sofar OldCoder: please leave the channel
04:13 OldCoder which call your right to make that request into question
04:13 sofar OldCoder: please leave the channel
04:13 OldCoder If you wish
04:13 sofar OldCoder: please leave the channel
04:13 OldCoder actual war
04:13 OldCoder sofar, you are flooding
04:13 sofar then leave the channel
04:13 OldCoder Is it to be actual war?
04:13 VanessaE and for the record, any good server host will not charge you for a DDoS.  they'll mitigate it.  I know, from having been a target myself a few times.
04:13 OldCoder VanessaE, that is not the issue
04:13 VanessaE and he's just repeating, you are flooding.  now TAKE IT SOMEWHERE ELSE.
04:13 OldCoder This host is a friend. The issue is affecting him.
04:14 sofar OldCoder: please leave the channel
04:14 OldCoder These cowards are hurting a friend.
04:14 OldCoder sofar, you are flooding
04:14 OldCoder Is it to be war?
04:14 OldCoder Do you think I won't quit a job
04:14 OldCoder That is now in jeopardy because of all of this
04:14 OldCoder And do what I must?
04:14 OldCoder Leave me alone
04:14 sofar OldCoder: please leave the channel
04:14 OldCoder Stop PMg my people
04:14 OldCoder Stop DDoSing me
04:15 OldCoder Stop saying that I "weird out" people by being "too detailed"
04:15 OldCoder Just stop it
04:15 VanessaE OldCoder: ENOUGH!
04:15 sofar OldCoder: please leave the channel
04:15 OldCoder My words exactly
04:15 OldCoder The decision is the group's. If I wake up tomorrow...
04:15 OldCoder and I find that anything has been escalated...
04:16 OldCoder Which would include ex post facto ban from this channel
04:16 OldCoder It is war
04:16 OldCoder You people should be ashamed of yourselves
04:16 OldCoder Enough, yourself, young lady :P
04:16 VanessaE you need to prove it was someone from here before you make a claim, OldCoder.
04:16 OldCoder The reaction is good enough. But do you deny it, honestly?
04:16 sofar this channel is not the place for legal accusations
04:16 OldCoder Speak the truth
04:17 OldCoder sofar, oh, really? But this is the channel
04:17 OldCoder of the Gods
04:17 VanessaE how can I deny something for which I have no information one way or the other?
04:17 sofar neither factual or implied
04:17 OldCoder Isn't it?
04:17 Hijiri anywhere with third parties isn't the place for legal accusations
04:17 rdococ -_-
04:17 Hijiri since that could be defamation
04:17 OldCoder That is not a legal basis for your assertion
04:17 OldCoder I fear no defamation
04:17 OldCoder Ever; since 2012
04:17 sofar OldCoder: please leave the channel
04:17 OldCoder sofar, you are tedious. I need to talk to my friend.
04:18 sofar please leave minetest entirely
04:18 OldCoder But understand... if I wake up and anything has been escalated
04:18 rdococ NONE OF US TOUCHED YOUR STUFF. NOW GO.
04:18 OldCoder The escalation may be regretted
04:18 OldCoder Is that what is desired?
04:18 OldCoder Must it be so?
04:18 rdococ ...
04:18 OldCoder ...
04:18 rdococ well, I don't know if anyone else touched your stuff.
04:18 rdococ but I know I didn't.
04:18 rdococ SO GO.
04:19 sofar OldCoder: please leave the channel
04:19 OldCoder rdococ, then "BE POLITE"
04:19 OldCoder Overnight, best decide: peace or war
04:19 OldCoder And this is the place to announce that
04:19 OldCoder It is one way or the other
04:19 OldCoder This has got to end
04:19 OldCoder If war is necessary, BTW, I am not very nice about it
04:19 OldCoder IRL
04:20 OldCoder Ask about a dozen attorneys, if you like
04:20 OldCoder Who were sicced on me
04:20 OldCoder I'll send you their home phone numbers
04:20 OldCoder Say Hi for me
04:20 sofar OldCoder: please leave the channel
04:20 OldCoder sofar, I am not escalating. You are.
04:20 OldCoder Does NOBODY but me understand deescalation?
04:20 sofar I'm still the person who is kindly asking you to leave
04:21 sofar so, take it like an adult
04:21 sofar go walk it off
04:21 VanessaE I'm being as kind as I can tolerate right now as well.  leave the channel.
04:21 OldCoder sofar, how dare you?
04:21 OldCoder "Take it like an adult" ?
04:21 OldCoder My host says it's continuing. They just lost one leg.
04:22 OldCoder Some system kicked in.
04:22 OldCoder $2,000. That's how much this has cost me.
04:22 OldCoder Not for the trademark. Lost work.
04:22 OldCoder Get off your high horse, sofar. What has this cost you?
04:22 VanessaE "lost work"
04:22 OldCoder Same to you, VanessaE.
04:22 OldCoder Yes, what about it?
04:22 VanessaE that argument won't fly here and you should know that.
04:23 sofar I advise you to cut your financial losses to a minimum
04:23 OldCoder Hm? It's not an argument.
04:23 VanessaE as for what this has cost me?  hmm... well add up three years of server hosting costs, whatever that comes to.
04:23 OldCoder I'm taking care of a dog tonight. He's hungry. Woof. Shall a dog whimper that you may feel superior?
04:23 OldCoder He's scratching for food right now
04:23 OldCoder I mean this rubbish, VanessaE
04:23 OldCoder The last 4 weeks
04:24 OldCoder I'm going to feed a dog. Presumably he won't bite me for doing so.
04:24 OldCoder If only people were animals of this nature.
04:24 sofar go walk it off, with the dog?
04:24 OldCoder You go walk it off
04:24 OldCoder But I must feed him right now
04:24 sofar please leave the channel as well
04:24 OldCoder Walk off 17,000 connections?
04:24 OldCoder sofar, I'll leave when the DDoS stops.
04:24 OldCoder If I'm kicked, I initiate
04:24 OldCoder IRL actions, not limited to legal
04:25 OldCoder Hm, that came out wrong. Or maybe it didn't.
04:25 VanessaE yeah, that came out VERY wrong on a publically-logged channel......
04:25 OldCoder I was being facetious, VanessaE
04:25 OldCoder It came out
04:25 OldCoder Exactly as I wished
04:25 OldCoder sofar, Corporate Counsels don't ignore me
04:26 OldCoder The last one tried
04:26 OldCoder to
04:26 OldCoder They brought in somebody who argues before State Supreme Courts
04:26 OldCoder After a few weeks
04:26 OldCoder He sort of went away
04:26 OldCoder I called him Christmas Day just to say Hi
04:26 OldCoder :D
04:26 sofar you're argueing in an IRC channel, you should probably get a really good lawyer
04:26 sofar also, please leave the channel
04:26 OldCoder sofar, I am not arguing at all
04:26 OldCoder Dog is waiting
04:27 sofar he needs you more than this channel does
04:28 sofar so, think of the dog, leave the channel, and take the dog for a walk
04:29 OldCoder sofar, you are being... the word is not polite. But those behind the attack are cowardly.
04:29 OldCoder And that assessment
04:29 OldCoder is perfectly on topic
04:29 OldCoder The core devs have developed hatred and prosecutable crimes
04:30 OldCoder It is on the new plan
04:30 sofar <OldCoder> The core devs have developed hatred and prosecutable crimes
04:30 sofar defamation
04:30 OldCoder Fact
04:30 OldCoder I can document
04:30 OldCoder the first part
04:30 sofar also, please leave the channel
04:30 OldCoder In detail over 4 weeks
04:30 OldCoder Also, please give it a rest
04:31 OldCoder (1) I leave when the DDoS stops (2) If I am kicked, the results will be satisfactory in the end to me
04:31 OldCoder None of this was necessary. You just had to leave me be. Without deprecation, attacks, basically rubbing salt in the wound.
04:33 OldCoder I've got kids, playing, right now; other countries. How nice that their playground is to be smashed up.
04:33 Zeno` I don't like being accused of things I did not commit
04:33 OldCoder Zeno`, I am dealing with the group. You are an individual.
04:33 OldCoder There are many kind people logged in.
04:33 OldCoder They ought to see this.
04:33 OldCoder And to understand just how far this has gone.
04:33 OldCoder And just how wrong it is.
04:34 OldCoder "Oh, look, somebody is disliked... throw stones, throw feces...
04:34 OldCoder make the stranger be dead"
04:34 sofar just, stop
04:34 sofar please leave the channel
04:34 OldCoder sofar, I ask the same of you. The first part.
04:34 sofar you're just looking for someone to acknowledge you
04:34 sofar for what reason?
04:34 OldCoder sofar, I am being DDoSed.
04:34 sofar don't even bother answering that
04:34 sofar just, go walk your dog
04:34 sofar please leave this channel
04:34 OldCoder If you wish to make other statements, discuss them or hush.
04:35 OldCoder You please leave this channel
04:35 sofar I've got another one
04:35 sofar please leave this channel.
04:35 OldCoder And I have no dog. I was helping somebody.
04:35 OldCoder please leave this channel.
04:35 sofar you're being disruptive.
04:35 OldCoder you're being disruptive.
04:35 OldCoder Adult, much?
04:35 OldCoder Grow up, yourself
04:35 OldCoder I have taken enough from the group that has attacked
04:35 OldCoder For a solid month now
04:35 OldCoder It ends
04:35 OldCoder Or it escalates
04:36 OldCoder Which is it to be?
04:36 sofar your decision
04:36 OldCoder I will never again be the boy
04:36 sofar so, go make it
04:36 OldCoder How is it my decision? Shall I stand there
04:36 OldCoder my blood dripping on the floor again
04:36 OldCoder And smile sweetly
04:36 OldCoder So sweetly
04:36 OldCoder That I shall be told
04:36 OldCoder I am not being disruptive?
04:36 OldCoder Never again
04:36 OldCoder Ever
04:36 OldCoder The attacks stop. Including from you, sofar.
04:37 OldCoder Or we go to the next level.
04:37 XtremeHacker What did I walk into? 0_0
04:37 OldCoder XtremeHacker, I'm being DDoSed
04:37 VanessaE XtremeHacker: just back away slowly and close the door....
04:37 OldCoder It is tedious
04:37 OldCoder XtremeHacker, best to stay in -project
04:37 OldCoder But it's up to you
04:37 * XtremeHacker LEaves -dev
04:38 OldCoder Host says he can tolerate even 17,000 simultaneous connections... Not sure indefinitely, though
04:38 OldCoder I might need to ask Bonsai Kitten about this
04:38 OldCoder Hm
04:38 OldCoder What sort of hardware is minetest.net hosted on?
04:39 OldCoder Does anybody know?
04:39 OldCoder What sort of network?
04:39 sofar are you threatening to DDos it?
04:39 OldCoder Is it really, really good? O_O
04:39 OldCoder Certainly not!
04:39 OldCoder It's just that
04:39 OldCoder If
04:39 OldCoder These people are randomly attacking Minetest
04:39 OldCoder And it is NOT just an attack on me
04:39 OldCoder Aren't the odds pretty good
04:40 OldCoder That they will take down Minetest.Net
04:40 OldCoder with something that makes 17,000 for a day or two
04:40 OldCoder Look puny?
04:40 OldCoder ^ Reasonable point
04:40 * OldCoder is shocked to realize that minetest.net may be at risk
04:40 sofar discussions about DDos-ing project servers (hypothetically) is certainly not appropriate for this channel
04:41 OldCoder Hypothetical is probably not on-topic. I contend that ongoing as in right now certainly is on-topic.
04:41 sofar your presence in this channel is disrupting the very goals of which it was created for
04:42 OldCoder sofar, do not even try to go there. Blame the victim. Sickening.
04:42 sofar Instead of discussing code and PRs, look at the channel now
04:42 OldCoder The victim is not at fault.
04:42 sofar you are doing more damage to the project than anyone else
04:42 OldCoder Rape is not justified by the fact that the victim is unable to fight back.
04:43 OldCoder Oh no O_O By saying I do not wish to be deprecated, dogpiled, lied about, DDoSed
04:43 sofar then go call your lawyer already, or call the authorities
04:43 OldCoder I am doing irreparable harm
04:43 OldCoder Oh no!
04:43 sofar but please, leave the channel
04:43 OldCoder sofar, it's martial arts
04:43 OldCoder The fact is, and I'm being pretty open about this
04:43 OldCoder My IQ is probably Hawkins level plus 5
04:43 OldCoder I learned this in 2012
04:43 OldCoder I could *see* everything
04:43 OldCoder laid out in legal actions
04:44 OldCoder And I realized that I could do *nothing*
04:44 OldCoder except when the other side moved
04:44 OldCoder Then they did
04:44 OldCoder And it was funny :D
04:44 OldCoder The trick is you don't let the other side choose the battlefield
04:44 OldCoder You will not be doing that to me
04:44 OldCoder The battlefield will not be DDoS
04:45 OldCoder And nobody in the project, including Perttu
04:45 OldCoder Hm; never mind the next part

05:00 VanessaE go back to bed :P
05:00 rdococ I can't
05:00 rdococ once I wake up I can't go back to sleep
05:04 OldCoder rdococ, try melatonin
05:04 OldCoder and I've responded to your question in PM
05:05 OldCoder rdococ, VanessaE, sleep is off-topic
05:05 OldCoder :P
05:07 rdococ left #minetest-dev
05:10 Hunterz joined #minetest-dev
05:36 OldCoder <VanessaE> so I'm gonna say one last thing:  don't ever bring any of this noise into -dev again. the channel has a specific subject...  if you are not discussing a patch or a pull request or a bug in the engine or _game or discussing making a change to it, or maybe making a quick one-liner joke, you're offtopic and need to take it somewhere else, regardless of what you think is or is not on-topic.
05:36 OldCoder VanessaE, deescalate.
05:36 VanessaE ^^^ private message sent to OC that didn't need to be repeated in here.
05:43 nerzhul joined #minetest-dev
05:43 OldCoder Just as shivajiva's PM dump did not need to appear in #minetest-project
05:43 OldCoder nerzhul, good morning
05:43 OldCoder Excuse me, PMg with Vanessa
05:44 nerzhul hi
05:44 OldCoder o/
05:53 nerzhul some noise on -dev unrelated to minetest development this night, hmmm
05:54 nerzhul can someone approve #5621 ? fairly trivial fix for an external contributor
05:54 ShadowBot https://github.com/minetest/minetest/issues/5621 -- Fix #5617 - respect message and reconnect parameters when shutting down immediately by orwell96
05:54 VanessaE wait, what?  something ON-topic?
05:54 * VanessaE falls over
05:55 nerzhul guys feature freeze is in 1 month, please finish all milestone 0.4.16 pr :)
05:55 VanessaE there's another odd shutdown issue that should be looked at - the client likes to hang on the way down.  Seems limited to singleplayer situations.
05:55 VanessaE hang to the point that I have to SIGKILL it.
05:56 nerzhul only when using shutdown command ? or in another way ?
05:56 nerzhul celeron55, can you add feature freeze date in topic (21st may), please ?
05:56 VanessaE well since it's singleplayer, usually ESC -> "exit to OS"
05:57 VanessaE I haven't noticed any problems with the separate server instance shutting down, other than that one bug that happened and was fixed, a few weeks back
05:57 nerzhul strange, is this triggered in every case ?
06:00 VanessaE noper
06:01 VanessaE it's pretty random
06:01 VanessaE next time I'll try to get a backtrace
06:01 nerzhul it's difficult :) maybe it can be related to some mods ?
06:04 VanessaE it could be, I don't know for sure
06:04 VanessaE however,
06:04 VanessaE since it requires a SIGKILL, probably not.
06:04 sofar #5619 updated, I think it's OK now

06:57 celeron55 i'll add some core devs as ops here
06:58 VanessaE thanks.
06:58 celeron55 ask me later if you don't want to have +o, i'll just pick randomly for now
07:00 VanessaE meanwhile, a user over on #minetest asks for a filtering feature for the in-client server list, i.e. show only servers that have PVP and mod "foo" installed, that sort of thing
07:04 OldCoder was kicked by ChanServ: User is banned from this channel
07:04 celeron55 how about that for now
07:05 celeron55 coming here with DDoS accusations is just stupid
07:06 VanessaE I *still* wonder who DDoS'ed him.
07:06 celeron55 he doesn't need to have this much attention
07:06 celeron55 i want people to be able to focus on minetest, not OldCoder
07:08 celeron55 maybe some script kiddie that happened to see some discussions; they tend to show their opinions that way
07:09 VanessaE perhaps.
07:12 celeron55 anyway, there is a limit for how much of my life i am going to waste with OC
07:13 red-000 wow my chat is spammed with OC

08:04 Zeno` hmm
08:06 nerzhul yeah, understood heh
08:06 nerzhul merging #5628
08:06 ShadowBot https://github.com/minetest/minetest/issues/5628 -- Fix various performance issues reported by cppcheck by nerzhul
08:06 nerzhul i didn't fixed all cppcheck issues yet, but ~65% are now done, the most criticals
08:07 VanessaE nerzhul: how much effect will those changes have
08:07 VanessaE (performance improvements always pique my interest)
08:07 nerzhul not very very huge, don't wait for a real difference, current problems needs a better approach than removing memory copis :p
08:07 Zeno` I guess cppcheck has been updated recently. About 3 months ago it didn't report much interesting at all
08:07 VanessaE fair enough.
08:08 nerzhul Zeno`: don't just do cppcheck, but cppcheck --enable=performance --std=c++03 src/ :)
08:08 Zeno` I'm meant to type all that?! :-o      ;)
08:08 nerzhul for the network part it remove 4 packet copies in the connection threads, which is systematic and can a little bit improve latency
08:09 nerzhul Zeno`: heh, you can --enable=all if you want but some things are not very interesting (style issues for example)
08:09 Zeno` that sounds easier :D
08:09 nerzhul after this PR merging, in performance issue if i remember are 4-5 memory copies and ~40 constructor optimizations
08:10 nerzhul please note when switching to C++11 we will have many more errors to fix which are shown by cppcheck to improve a little bit more performance due to new compilers/standards
08:11 nerzhul oh nice !
08:11 nerzhul https://gitlab.com/nerzhul/​minetest/pipelines/7774250

08:17 ShadowBot https://github.com/minetest/minetest/issues/5629 -- Gitlab-CI enhancements by nerzhul
08:17 nerzhul it doesn't affect github but i really want to continue and finish daily builds, and this is the second step :)
08:17 nerzhul maybe at the end make gitlab push some artifacts to github or somewhere else for end users
08:18 celeron55 if there's no other way to control gitlab, i guess it's okay
08:19 celeron55 it's kind of silly though
08:19 nerzhul .gitlab-ci.yml is equivalent to .travis.yml :)
08:19 celeron55 travis is silly also
08:19 nerzhul i prefer gitlab-ci it's a little bit simple to handle and docker usage permit to test on many systems, unlike travis which only uses ubuntu
08:19 celeron55 it's like they use our project for marketing by forcing their file to be there

09:07 HiBitches I'll be back in 3 minutes
09:07 HiBitches Red, if they do
09:07 HiBitches alternative is to go +m on channel
09:07 red-000 go to your own channel
09:07 HiBitches There is a fallback plan for that
09:07 kaeza so mature
09:07 HiBitches red-000, PM, please, no sneeze, you are offtopic
09:07 HiBitches kaeza, I agree
09:07 kilbith how about to go fuck yourself

09:08 HiBitches This is offtime and I am lawabiding
09:08 HiBitches offtopic, sorry

09:08 nerzhul VanessaE, oh i didn't knows that
09:08 HiBitches Ban or nothing. And ban means HMA.
09:08 red-000 Isn't ban evading agaist freenode rules?
09:08 HiBitches It surely is.
09:08 HiBitches Shocking.
09:09 HiBitches So is DDoS ofc
09:09 nerzhul i didn't ban just kick
09:09 HiBitches Sigh
09:09 HiBitches Let me sleep
09:09 VanessaE nerzhul: it also works to keep chat in an IRC channel from propagating to minetest server instances that are in that channel via kaeza's IRC mod.
09:09 nerzhul oh, it's because it's handled like this in the reading components then
09:10 red-000 nerzhul, oldcoder already got banned
09:10 HiBitches That was probably foolish
09:10 HiBitches as he is insane and not age 14
09:10 HiBitches and has sufficient funds
09:10 HiBitches to be rather inconvenient
09:10 HiBitches Oh no
09:10 HiBitches He hires detectives
09:10 HiBitches IRL
09:10 kaeza potato
09:11 HiBitches Did you know that? He's really quite a B*tch
09:11 HiBitches He likes to spread U.S. SSNs around
09:11 HiBitches for US people
09:11 red-000 ?
09:11 HiBitches vanessa, PM, truly; RBA did care for you
09:11 red-000 potato?
09:11 HiBitches I think
09:12 HiBitches It's a potat-Oh po-tah-to reference
09:12 VanessaE potato.
09:12 red-000 I'm confused
09:12 HiBitches It is a criticism of obsession
09:12 kilbith stop answering him already
09:12 red-000 why is everyone saying potato?
09:12 HiBitches A US meme of decades ago
09:12 kaeza potato!
09:12 HiBitches red-000: it's a meme
09:12 red-000 !??
09:12 VanessaE hash browns. :)
09:12 HiBitches kilbith don't be a, um, bith

09:13 kaeza nerzhul, ^
09:13 HiBitches kilbith I'd be back in 2 minutes
09:13 red-000 I'm really confused
09:13 HiBitches Tomorrow I'll have 700 IPs
09:13 HiBitches Just as LM had
09:13 celeron55 what on earth is this now
09:13 HiBitches That is kid stuff
09:13 HiBitches It is potato meme
09:13 kilbith should we request a k-line to the Freenode admins ?
09:13 HiBitches kilbith this is a random IPV4
09:14 HiBitches Tomorrow I sign up for HMA
09:14 HiBitches After that I hire detectives
09:14 HiBitches Are you in the US BTW? But you are German
09:14 HiBitches *sad*
09:14 red-000 pretty sure ban evading is a k-linable offence
09:14 HiBitches It is, yes\
09:14 HiBitches Indeed
09:14 HiBitches So is DDoS

09:17 nerzhul kilbith, it's not a good idea on this channel

12:17 ShadowBot https://github.com/minetest/minetest/issues/5186 -- Soft node overlay by juhdanad
12:19 juhdanad My problem is that I use Ubuntu, and the provided pahole has a bug and does not work with the built object files.
12:20 juhdanad I also tried to build the patched version from source, but a required library is not available anymore.
12:20 juhdanad So I can not test if the memory layout of TileLayer and TileSpec is correct.
12:25 VanessaE pahole?
12:25 juhdanad An utility program to find holes in the memory.
12:25 VanessaE ok
12:28 proller joined #minetest-dev
12:40 ThomasMonroe joined #minetest-dev
12:41 nerzhul juhdanad, it's sofar who ask you to do that ?
12:43 juhdanad He did not ask me. I wanted to do this because of this line comment: https://github.com/minetest/minetest/commi​t/93c1d511e3880acf15a656f1653ce5853dd1d362​#diff-f44f50a96d13d2421bd5301b7511ee26R288
12:52 sfan5 can't your use a chroot or vm to use pahole
12:53 juhdanad No. I can't compile it.
12:54 sfan5 yes that is why you should use a chroot with a different distro
13:04 Zeno` If you have to try a different distro then the optimisation is bogus
13:05 Zeno` actually that whole comment is bogus
13:05 juhdanad Well, I guess the best would be to use tile spec references instead of memory copy...
13:05 Zeno` that may be the case but it doesn't make the comment any more valid
13:05 Zeno` wait
13:05 Zeno` it's a pointer anyway :/
13:06 Zeno` where is the memory copy?
13:08 juhdanad https://github.com/minetest/minetest/b​lob/master/src/mapblock_mesh.cpp#L678
13:08 juhdanad is an example
13:09 Zeno` I don't like it. Optimising that way is bad
13:10 Zeno` even worse, who knows what architecture this is being built on?
13:10 Zeno` it's a bit crazy
13:11 kilbith it's 50000% faster, Craig
13:12 Zeno` if it's only 50000% it's not worth it
13:12 cx384 joined #minetest-dev
13:12 juhdanad But it won't be easy to use pointers everywhere, as some parts of the tile specs are modified (rotation, color)
13:12 Zeno` juhdanad, huh?
13:13 juhdanad What do you not understand?
13:13 Zeno` Why you cannot modify an object that is pointed to
13:14 Zeno` that's kind of the point of pointers :/
13:15 juhdanad So currently a mapblock mesh contains lots of tile specs. These contain redundant information - texture, animation. So it would be better if these meshes only had pointers instead of tile spec copies.
13:16 DS-minetest joined #minetest-dev
13:17 juhdanad If you have a flat block with grass, it creates 16 copies of the grass node's tile spec: 16 times the texture pointer and animation data.
13:23 Zeno` so remove the comment?
13:24 juhdanad I don't think it should be removed, as now TileSpec is better optimized.
13:24 agrecascino joined #minetest-dev
13:24 Zeno` It is?
13:25 agrecascino uh
13:25 juhdanad Yes, some holes were removed by sofar.
13:25 agrecascino is anyone working on a client side lua implementation
13:26 Zeno` I don't get it juhdanad
13:26 juhdanad agrecasino: it is already implemented.

13:27 agrecascino heh
13:29 agrecascino so when did it like get implemented?
13:30 juhdanad To sum up: sofar reorganized TileSpec so it requires less memory. Meanwhile my PR also changes TileSpec. The only problem is that I can not check for holes in my PR, so it might not be as optimal as possible.

13:58 Taoki Thought I'd do my periodic asking for this question: Has any progress been made on shaders and graphics, including RBA's latest in-the-works codes?
13:59 Taoki Or more specifically: Is there any hope of seeing any of the following features make it into master soon: Extruded (3D-fied) plantlike, bloom shader, depth-of-field shader?
13:59 Taoki (those were the ones I was most interested in, and obviously still am)
14:02 juhdanad There's only one enhancement I know of: undersampling.
14:02 Taoki Interesting. Any screenshots?

14:03 Taoki Thanks
14:03 Taoki Cool. Can help with offering a pixelated, Doom-like art style :)
14:05 Taoki Woah... client-side Lua scripting is a thing now? Noticed it in one of the pull requests. Been away for quite some time it seems.
14:08 agrecascino Taoki, yeah, i stopped paying attention around 8 months ago, for various reasons
14:08 halt_ joined #minetest-dev
14:10 Calinou Taoki: current undersampling kind of sucks because you can't set it to be filtered linearly
14:10 halt_ joined #minetest-dev
14:10 Taoki Fair enough
14:10 Calinou I'd like that for my 4K laptop, while I want Minetest to render at 1080p (else it's unplayable), I don't want it to be blocky
14:10 Calinou the way it's implemented makes it non-trivial to implement that
14:14 agrecascino uh, i have to ask
14:15 agrecascino who thought it was a good idea to have 4k displays on laptops that can barely into 3d graphics at 1440p
14:15 Taoki Heh. Also, I assume that to this day, a working implementation for VBO was still not achieved :P
14:15 Taoki I think it's like, half a decade now since we're trying to get working VBO in master, for that essential performance improvement.
14:18 agrecascino wait
14:18 Calinou I think VBOs were merged? maybe enabled by default
14:18 agrecascino i have to ask, if we aren't using vbos, what are we using?
14:18 Calinou https://github.com/minetest/minetest/b​lob/master/minetest.conf.example#L329
14:18 Taoki Calinou: That would be wonderful
14:18 Calinou enabled by default, it seems
14:19 agrecascino i'm pretty sure minetest doesn't use opengl 1.1
14:19 Taoki agrecascino: Drawing by the CPU each frame, which was very slow
14:19 Calinou it's been here for at least a year, according to Git blame
14:19 Taoki Oh... amazing!
14:19 agrecascino i mean
14:19 Calinou agrecascino: Minetest uses whatever OpenGL is supported by the system
14:19 Taoki Ok... might have forgotten then
14:19 Calinou currently, I don't think any OpenGL 4.x features are used, although OpenGL 3.x may help in places, I don't remember
14:19 agrecascino my current attempt at a game engine uses gl 1.1 interwhatever mode calls
14:20 agrecascino but that's because opengl 3 is hard and a waste of time for me
14:20 Calinou immediate mode (and thus, OpenGL 1.x) has been obsolete since like 10 years
14:21 agrecascino just because it's obsolete doesn't mean it's not easy
14:21 Calinou well, it's like using mysql_* functions in PHP, it shouldn't be done in 2017 :)
14:22 Calinou and it's not like you can make anything good-looking with OpenGL 1.x anyway
14:22 Calinou (barring pixel art games, which are their own thing)
14:22 agrecascino obviously, but it's still super easy to use
14:24 agrecascino my laziness succeeds my reason in decision making
14:28 Taoki https://cloud.githubusercontent.com/assets/825418/​25281686/c1c3319c-26b6-11e7-89ed-ccaafcc2b0c3.png Weird bug that just started happening on my machine.
14:28 Taoki Reported it here for now: https://github.com/minetest/minetest/issues/5631
14:33 agrecascino Taoki, surprisingly pretty
14:34 Taoki Still a bug, but true :P
14:34 agrecascino uh
14:35 agrecascino can client-side lua scripts play audio
14:36 Fixer agrecascino: 4k on laptops is a myth, 99% own 1366*768 garbage
14:36 agrecascino Fixer, it definitely exists
14:37 agrecascino or at least, too high-res-for-the-laptop-hardware laptops exist
14:37 Fixer i see even 1000 usd laptops has this 1366*768 garbage included...
14:37 Fixer what a joke
14:38 agrecascino ie: friend's laptop has like 2880xsomething screen
14:38 agrecascino Fixer, it's even worse that most are TN panels
14:38 Fixer yep
14:38 agrecascino also
14:38 Fixer TN 1366*768 garbage even on 1000+ usd laptop
14:38 agrecascino minetest has endian issues
14:39 agrecascino Fixer, i have a sager laptop with a 1080p screen
14:39 agrecascino worst tn panel evr
14:39 agrecascino ever*
14:39 agrecascino it's 18 bit with dithering
14:39 agrecascino the worst dithering i've ever seen
14:39 Zeno` mine is true 1920x1080
14:39 agrecascino to the point where dark grays produce weird line artifacts on the screen
14:40 agrecascino in linux i can disable the dithering, and the artifacting goes away, but it's still pretty bad
14:40 Taoki Perhaps client-side Lua also means a decent weather system. People tried doing particle weather in the past, but it sucked because you had to move a particle spawner on the server based on the player's position: The server lagged, rain would start dropping from another location.

14:42 Taoki Can I download it from somewhere else?

14:44 Taoki That would be great
14:44 Zeno` protracker is not as easy as you'd first think
14:44 Fixer Taoki: you said you recompiled it, why can't you recompile one commit back, it is pretty easy?
14:44 Taoki Also, have any thoughts been given on a pixelated large font, similar to Minecraft? Not to copy MC per say... just always wondered if that would look and feel better.
14:44 juhdanad Taoki: maybe what you are seeing is #4986. Now it is possible to re-colorize nodes.

14:45 Taoki Fixer: Also, which commit in particular do you recommend I try?
14:45 Fixer Taoki: i do it like this, go into /minetest and run: git checkout 2ad74a9
14:45 Fixer Taoki: then compile it
14:46 Fixer Taoki: after that you can go back by typing: git checkout master (if i remember correctly, if master does not work try head or origin)..

18:21 benrob0329 #5586 is light stored in a signed int?
18:21 ShadowBot https://github.com/minetest/minetest/issues/5586 -- Add negative value for node light_source.
18:22 Krock unsigned byte
18:22 benrob0329 Oh, nvm
18:23 benrob0329 How hard would it be to change to a signed byte?
18:24 sfan5 hard
18:24 benrob0329 is light source seperate from light level?
18:25 paramat 'stored' in what way, in the world database or as a light source parameter?
18:25 sfan5 doing this kind of change requires deep knowledge of the light system, which you don't seem to have; sorry
18:27 Krock signed byte is nonsense, regarding how we store the light values right now: 4 bits for daylight, 4 bits for at night, thus light max = 15
18:27 Krock alone in the backwards compability would be a challenge (to not forget anything)
18:28 DS-minetest (also negative light is unrealistic)
18:28 Krock > unrealistic  > running with 20 n/s
18:29 paramat mapnode light levels are positive, so using signed ints would mean we are using twice as much memory as we need to
18:29 Krock btw, int16 or int32?
18:31 benrob0329 sfan5 true, I was thinking a negative source would simply subtract said light rather than add it, but from reading light.cpp/h this probably wouldn't be easy.
18:32 paramat nope the lighting method is built around positive values, negative ones would not automatically work
18:33 paramat so i'm closing the issue :]
18:33 benrob0329 The light value would remain the same, but light_source would change and extra clauses added

18:54 celeron55 the only change to the datatypes of the light system might be extending it to 16 bits total, but it might be completely hazardous to performance as light propagation is recursive and probably gets really expensive after something like 15 nodes
18:54 celeron55 the only remotely reasonable*
18:55 celeron55 well except for modifying of the meaning of the light banks a bit (which is already a PR?)
18:57 celeron55 (also, making mapnode larger from its current 4-byte size is probably also hazardous to performance)
18:58 celeron55 it would be nice if subgames or something could decide such performance tradeoffs but it's not really possible to implement anything like that
18:58 sfan5 should've used java
19:06 sofar juhdanad: TileLayer holes are OK, it's not so bad
19:06 sofar 2 holes of 6 bytes, no big deal
19:06 sofar it's 2 bytes larger than a cacheline though without the holes
19:06 sofar so maybe we can save 2 bytes and get it in one cacheline?

19:08 sfan5 hm, and ARM-based cpus?
19:08 sfan5 indeed
19:08 sofar 66 bytes for a struct is just a big overhead for those last 2 bytes
19:08 sfan5 i guess no chip designer is weird enough to have odd-sized cache line

20:50 Taoki Indeed I do
20:50 Taoki Apparently however, Minetest constantly crashes
20:51 juhdanad Taoki: when does it crash? When you exit the game?
20:52 Taoki No... sometime randomly during the game
20:52 Taoki And it's not a Lua crash to the main menu... engine crash
20:52 nerzhul sfan5, as we don't change the particle code source very often, why not no ? :)
20:53 nerzhul a memleak was introduced today juhdanad
20:53 nerzhul in your PR
20:53 juhdanad I know, but I already fixed it, sorry.
20:53 nerzhul cppcheck showed me an error when i fetched before preparing my 5th PR on cppcheck performance fixes
20:53 nerzhul temp_buf->append(v, mesh_buffer->getVertexCount(), indices,
20:53 nerzhul mesh_buffer->getIndexCount()); ?
20:54 nerzhul is this fixed ?
20:54 juhdanad This is not, I will check.

20:54 nerzhul [src/mesh.cpp:418]: (error) Memory leak: temp_buf
20:55 nerzhul in EVT_STANDARD you returned temp_buf, it's fine
20:55 nerzhul for others you return clone which is NULL because we never set it in the function
20:55 nerzhul i think it's not normal i think no ?
20:55 nerzhul also in this function the u16* case is unneeded
20:55 nerzhul mesh_buffer->getIndices() is already u16*
20:56 nerzhul please send us very fast a fixing PR
20:57 ThomasMonroe left #minetest-dev
20:58 juhdanad I'll try.
21:02 Taoki nerzhul: Is that related to my crash too?
21:02 juhdanad If you use tangent vertices, probably yes.
21:02 nerzhul i'm pretty sure
21:02 nerzhul juhdanad, you hsould never return null i think ?
21:03 juhdanad Yes, I intended to return at the end of each case.
21:03 Taoki tangent vertices? Is that an option?
21:03 Taoki But in any case, gladly awaiting a fix
21:05 juhdanad nerzhul: how can I enforce Minetest to use tangent vertices?
21:06 nerzhul no idea, use taoki world ?
21:07 nerzhul if i look at the code
21:07 nerzhul before temp_buf->drop(); was called
21:07 nerzhul and dst_mesh added temp_buffer
21:08 nerzhul in every case
21:08 nerzhul and we returned clone
21:08 nerzhul with your pr
21:08 nerzhul dst_mesh was renamed clone
21:08 nerzhul we never drop
21:08 nerzhul and in the working case we return temp_buf
21:08 nerzhul i think we should return temp_buf everytime and remove clone
21:08 nerzhul or re_use dst_mesh with addMeshBuffer
21:09 nerzhul juhdanad, https://lut.im/3LkJxDGyx4/we6bLDzXdltoTizg.png
21:10 nerzhul Taoki, you can modify code right ?
21:10 nerzhul and you crash is systematic, right ?
21:10 Taoki Depends on what code. And it's random but consistend, happens unpredictably
21:11 nerzhul it should be triggered on specific event using those vertices, how many time (mean) before it happens ?
21:12 Taoki Not sure what you mean by times. It happens sometimes.
21:12 Taoki Although I think it happened twice in the same point once
21:13 juhdanad Okay, I enforced tangent vertices and I see the crash. Now I'll attempt to fix...
21:13 juhdanad Taoki: probably an item's mesh causes the crash. Or a special node on the map.
21:14 Taoki Makes sense. Glad you found a way to test
21:14 nerzhul juhdanad, first remove clone and return the temp_buf (and rename it to another name if it's not temporary, or restore prvious behavour)
21:14 Taoki I've been away from Minetest for a bit like I said... would have been harder, as I might have forgotten a few things
21:15 nerzhul nore, be careful you merged this , i know the PR was very huge :(
21:15 nerzhul when i will finished with CPPcheck fixes i think i will provide a PR to add a cppcheck verification to show the static errors found, without this a random crash + memleak could happen
21:16 nore nerzhul: the soft node overlay? it was not me who merged it...
21:16 Taoki 777 MB of RAM. I don't think Minetest should be using that much...
21:16 Taoki So might confirm the memleak as well
21:17 nerzhul oh sorry nore, i misread github log you have same colors as juhanad :p
21:18 nore lol :D (although not exactly, mine is more pink :p)
21:18 nore no problem anyway :)

21:26 nerzhul also remove break after return, it's unreached
21:26 nerzhul yes
21:26 juhdanad Or rather with sanity_check?
21:26 nerzhul sfan5, ?
21:27 nerzhul what do you think ?
21:27 nerzhul i think it's a pure devel error, it should not be reported to user in release mode ? i don't see how can that happen
21:28 nerzhul you can use sanity_check yes, why not
21:32 sfan5 return null sounds fine to me
21:32 nerzhul sfan5, you prefer a crash when using the object than an assertion for a unhandled switch case ?
21:33 nerzhul i don't really know where this pointer will finish but it can be difficult to track
21:33 sfan5 then throw in a sanity_check(false);
21:33 juhdanad cloning should be always successful.

21:34 sofar I've lost internet at home
21:34 nerzhul maybe we can remove it no ?
21:34 nerzhul i don't see any interest to have a lua call to trigger segfaults, zerodivision and exception
21:35 nerzhul sapier told: "Catch some error situations when mod used without thinking about it"
21:35 nerzhul wtf
21:35 nore nerzhul: it's only these in debug builds and I guess it's there to check if error handling works well, probably?
21:35 juhdanad nerzhul: updated.
21:36 nerzhul nore i don't see how you want to handle a segfault :p
21:36 nore ehm
21:36 sfan5 nerzhul: that function looks useless
21:36 nore yeah, maybe remove it
21:36 nerzhul sfan5, i will push a commit to remove it
21:36 sfan5 and clang does actually not allow you to cause a segfault by deref'ing a NULL pointer
21:37 nerzhul exact
21:37 nerzhul nore
21:37 nerzhul note*
21:37 nerzhul it's called in games/minimal/mods/errorhandler_test
21:37 nerzhul i remove it ?
21:37 nerzhul it's related to /exceptiontest in minimal
21:37 sfan5 yes
21:38 nerzhul okay i will provide a trivial pr for this
21:39 Taoki Found another bug BTW...
21:39 Taoki Hit a mob once: Their model becomes white, but doesn't go back. Every time you hit an entity and damage it, it becomes whiter until you reconnect.
21:41 Hijiri are you sure it's not a bug with the mod?
21:42 Taoki Don't see how it could be, so yeah. I don't colorize entities or anything
21:42 Taoki Although I used colorized mixed textures
21:43 Taoki Appended with ^ in the texture string. But that's all
21:43 Hijiri what does the code look like?
21:43 Hijiri oh
21:43 Hijiri no punch code?
21:43 Hijiri that does sound like an engine bug then
21:44 juhdanad I see it too, will investigate...
21:45 Taoki Other than that, the glass_framed drawtype does some z-fighting, when you see the backface against a wall. That's really unimportant though, but just thought to mention

21:54 paramat Taoki tangent vertices is enabled when you use bumpmapping/normalmapping/parallax occlusion shaders
21:54 Taoki paramat: Oh... I use those in that case
21:55 nore sofar: I'll try to modify it not to copy things that are not needed
21:55 sofar juhdanad: don't worry
21:55 nore (i.e. you don't need to copy the whole vector, and copying a vector is probably expensive even if there is nothing in it)
21:56 sofar nore: it's gonna be hard, maybe shrink shader_id to u16? but that comes from the protocol I think
21:56 nerzhul copy an empty vector is not expensive as memory area is less than 8 bytes :)
21:56 nore nerzhul: vector is already 24 bytes long, and I think it allocates another area for the new vector
21:56 nore I mean the vector struct is 24 bytes long
21:57 juhdanad nerzhul: rebased.
21:57 nore including a pointer to data
21:57 nerzhul nore, can you show me the code line ?
21:57 nerzhul juhdanad, nice, i will merge it after CI
21:57 nerzhul but CI seems very busy
21:58 nore nerzhul: hmm, it's the animation vector is TileInfo that is now TileLayer I think
21:58 nore *in
21:58 juhdanad sofar: the alpha bits of the layer's color is not used currently.
21:58 juhdanad That's 1 byte.
21:58 sofar we need 2 bytes, and alignment :)
21:59 troller joined #minetest-dev
21:59 nore alignment is more difficult
21:59 nerzhul sofar, does that change really something at this moment as we have many other areas to improve ? :p
21:59 sofar yes, this is a really hot struct in the client
22:00 nore but anyway I'll try to modify the code to make it copy only what is needed, I think it would get the hot part to 20 bytes only
22:00 nore so 2 of them would even fit in a single cache line
22:00 nerzhul is the vector size dynamic or static ?
22:01 nore (well, 3 if we didn't have these alignment restrictions)
22:01 nore nerzhul: doesn't change for a fixed TileLayer, but size depends on the TileLayer
22:02 nore (i.e static as does not change within each instance)
22:03 Amaz joined #minetest-dev
22:08 juhdanad nerzhul: I've found the reason why entities become continuously brighter when you punch them: it's a const reference.
22:08 Fixer sfan5: funnily enough i have impression that tool dig speed was increased, for example diamond shovel or pickaxe
22:09 nerzhul juhdanad, can you be more precise
22:10 nerzhul i don't see why a const ref can trigger that
22:10 juhdanad When some time has elapsed, the entity wants to return to its original texture.
22:10 juhdanad Therefore, 'updateTextures(m_previous_texture_modifier)' is called.
22:10 nerzhul okay, and ?
22:11 benrob0329 joined #minetest-dev
22:11 juhdanad Then it does: m_previous_texture_modifier = m_current_texture_modifier;
22:11 nerzhul const ref just prevent copying the texture modified but it in updateTexture it's copyied, it's done
22:11 juhdanad And m_current_texture_modifier = mod;
22:11 nerzhul sorry but not relevant
22:12 nerzhul mod is a reference to m_previous
22:12 juhdanad Where mod is a reference to m_previous_texture_modifier.
22:12 nerzhul and m_current_texture_mod = mod; copy the reference content
22:12 juhdanad Bot mod was overwritten in the previous command.
22:12 nerzhul m_previous_texture_modifier = m_current_texture_modifier;
22:12 nerzhul m_current_texture_modifier = mod;
22:12 nerzhul i think the problem is that
22:13 nerzhul no ?
22:13 nerzhul oh okay
22:13 nerzhul i see
22:13 nerzhul exact
22:13 nerzhul we don't copy it, and we use it without swapping
22:13 nerzhul anoying side effect
22:14 juhdanad So the parameter there is not const, because you have a non-const pointer to it too.
22:14 nerzhul i'm thinking about it, wait a minute :)
22:14 juhdanad (at content_cao.cpp:1325)
22:14 nerzhul if (mod != m_previous_texture_modifier)
22:14 nerzhul m_previous_texture_modifier = m_current_texture_modifier;
22:15 nerzhul that should do the trick
22:15 nerzhul can you try it ?
22:16 juhdanad Well, it works, but I don't understand yet why.
22:17 nerzhul with my fix ?
22:17 juhdanad Yes.
22:17 nerzhul it's simple, if you set previous with current, when you set current to mod, current = previous = current => no change
22:18 nerzhul but it's not the right fix i think
22:18 nerzhul copy the string solve the problem, but it's not very elegant to cut the previous override, because previous is not current then
22:19 juhdanad No. There are three different values there: the previous, the current and the next (mod) texture modifiers.
22:19 juhdanad *No, it is not the right fix.
22:20 nerzhul i'm searching if it's possible to keep the const ref benefit
22:20 nerzhul i see how it's possible, jsut copy the variable before usage
22:21 juhdanad But if you copy it, there is no point in sparing a copy.
22:21 nerzhul in 2 usecase on, in 3 usecases yes
22:21 nerzhul 3 vs 3
22:21 nerzhul then, rollback this sounds the only correct solution
22:22 nerzhul very tricky bug
22:23 nerzhul or we can do better
22:23 juhdanad Maybe keep the const ref, but copy the string when you call the function with the member!
22:24 nerzhul yeah i think about that
22:24 nerzhul but no real benefit, another copy
22:25 juhdanad No, there is a call 'updateTextures(m_current_texture_modifier + "^[brighten")'
22:25 nerzhul yes u know, there is 3 calls like this, and three cases to member variables
22:26 nerzhul https://pastebin.com/KckCCDr0 ?
22:26 nerzhul swap if we are working on members, else do the regular way

22:28 nerzhul sofar, don't the compiler reorder things for CPU ?
22:28 juhdanad nerzhul: looks good to me.
22:28 nerzhul juhdanad, you tested it ?
22:28 juhdanad Not yet, wait...

22:28 ShadowBot https://github.com/minetest/minetest/issues/5637 -- Remove lua crash triggering by nerzhul
22:28 sofar nerzhul: this is from the binary, and no, reordering doesn't happen except for initializers
22:29 nerzhul sofar, it's strange that compiler doesn't try to make binary more efficient for their architecture
22:32 juhdanad nerzhul: the first line should be: 'if (mod == m_current_texture_modifier) {', shouldn't it?
22:32 juhdanad Unfortunately the patch doesn't work.
22:33 nerzhul okay, i will just revert to a copy, we will see later
22:34 sofar ItemDefinition is 6 cachelines of which 2.5 cachelines is just c_strings[32]
22:35 sofar ContentFeatures is huge, lol
22:35 nerzhul ContentFeature is a huge thing yes
22:35 nerzhul i'm pushing a const ref revert on updateTextures
22:36 sofar /* size: 4272, cachelines: 67, members: 57 */
22:36 sofar 67 ... 67 cachelines
22:36 sofar it wastes half a cacheline on paddings and stuff
22:37 juhdanad sofar: when I write f.light_source, then all 67 cachelines are loaded?
22:37 sofar no, it doesn't work like that
22:38 sofar it'll load the part of the struct that isn't in cache, in 64byte segments
22:38 sofar for what is needed
22:38 nerzhul sofar, ContentFeature is not very often updated it's write once in majority cases
22:38 juhdanad Okay then! Fortunately ContentFeatures are passed as references.
22:38 nerzhul juhdanad, i pushed the revert on master for this const ref
22:39 nerzhul juhdanad, it was not the case everywhere 2 years ago :p hopeful Zeno` and me worked on removing that :p
22:39 nerzhul this struct is very dangerous i think the copy constructor should be removed if possible when using C++11 to prevent bad usages :)
22:39 juhdanad I'm sure Minetest became significantly faster when you did that.
22:39 sofar nerzhul: is ContentFeatures read a lot in hot (render/mesh update) paths?
22:40 juhdanad I only know it is read a lot at light updates.
22:40 sofar the trick isn't to make it smaller per se
22:41 juhdanad Oh, yes, mesh update also reads content features!
22:41 sofar the trick is to put the hot items in it all together in a single cacheline
22:41 sofar suppose that mesh and light update only need 10-15 items
22:41 sfan5 nerzhul: i think some of your fixed introduced this warning http://sprunge.us/YFQM
22:41 sofar and now they're in 13 of the 67 cachelines
22:41 sofar maybe we can make that 2 cachelines
22:42 sofar and reduce memory pressure by a factor 5+
22:42 nerzhul sfan5, why my compiler doesn't report it...
22:42 sfan5 clang 4.0 on arc
22:42 sfan5 h
22:42 sofar which change?
22:42 nerzhul i think my clion uses gcc atm instead of clang
22:43 juhdanad Good night to everybody! I hope I successfully cleaned up everything after myself.
22:43 nerzhul it was reseted when testing jsoncpp defaults heh, i switched, it's better now
22:43 nerzhul okay i see, a cleanup to remove
22:43 nerzhul oh no, just a const ref to re-link :)
22:44 nerzhul it also permits to show gui::IGUIElement* m_parent; in guiFileSelectMenu warning, nice
22:44 nerzhul lol
22:45 nerzhul compilers are crazy
22:45 nerzhul if you set m_parent(parent) in constructor it reports m_parent as unused
22:45 nerzhul and if you do m_parent = parent in constructor it doesn't
22:46 nerzhul i'm testing it and i will push the double warn fix
22:46 sofar nerzhul: `class Client`
22:46 sofar watch this

22:47 sofar /* sum members: 2045, holes: 16, sum holes: 940 */
22:47 sofar lmao
22:47 sofar none of it is hot, though, I think
22:47 nerzhul rah cmake reseting RUN_IN_PLACE when changing compiler
22:48 nerzhul client is central but env is more used than client in terms of attributes
22:48 nerzhul also client has a ClientEnvironment object inside it
22:49 sofar that one actually sounds like a pahole bug
22:52 nerzhul okay pushing a trivial fix for warning + guiFileSelectMenu header clean on unused attributes (never called anywhere)
22:53 nerzhul pahole is not simple i think :)
22:54 sofar using it right is hard
22:54 sofar we stumbled on TileSpec being bad due to profiling
22:55 nerzhul i also merge #5636 (travis is yellow, but C++11 build will finish soon and is not concerned by this change).
22:55 sofar if the problem doesn't show in profiling it's probably not so bad

22:56 nerzhul i'm off, see you tomorrow guys, thanks for your help, and good luck sofar but don't forget we have 180 PR now (argh)

23:01 Fixer !tell nerzhul I wonder if your building system can be used for making flatpaks... https://forum.minetest.net/vi​ewtopic.php?f=42&amp;t=15336
23:01 ShadowBot Fixer: O.K.

23:58 VanessaE so it does something similar to worldedit's `//replace air air` trick?
