@Learath2 you here for a short discussion?

10:25

nemo: do you have map download in hedgewars?

10:25

@Learath2 (regarding stronger hashes for maps)

@heinrich5991 Jeder client springt bei mausbewegung sofort in irgendeine ecke meines bildschirmes so wie hier: https://streamable.com/grqjw Ich bewege meine maus nur minimal. Egal ob borderless, windowed oder fullscreen Bei borderless und windowed springt der cursor weniger aber trotzdem

@Fluni can you go into the console (f1) and enter inp_mousesens and ui_mousesens?

inp is 140; ui = 370

that sounds like a lot, although not terribly much

13:52

I have them set to 96 and 100, respectively

well my dpi is on 400

13:52

:p

ah

13:52

I don't know what causes this.

13:52

have you tried using inp_mouseold or sth?

13:53

I don't actually know what that does

13:53

@Learath2 you look online. up for a short discussion about strong map hashes?

so no clue?

not from me, no

13:56

you say that this happens with every client? also for vanilla?

yes

@heinrich5991 am outside but we can discuss sure

so

14:03

let sha512 be our secure hash for this discussion

14:03

I added a network message that tells the client which sha512 the map of the server has

14:03

theoretically, this is as simple as switching to that map naming scheme in downloadedmaps:

14:03

mapname_<sha512>.map

14:04

the problems come with the backward-compatibility, obviously

Yeah thats what I was going to type

so

14:05

we receive map name and crc and sha512 from a server

14:05

we don't have mapname<sha512>.map, I guess we should be looking for mapname<crc>.map and check whether that matches the sha512, if not, download from server

14:05

easy enough

14:05

we receive map name and crc from a server

14:06

we can't tell which map the server wants

14:06

my suggestion would be something like: store which IP offered which (mapname, crc) with which sha512, and only load the map from the hdd if we've seen it on the server before

14:07

i.e. first time visiting a server without crc support always means downloading the map again

Hmm

*wtihout sha512 support

Why do you bother with ips? Lets just store a map from crc->sha512

but we have a server that won't tell us which sha512 it expects

14:09

and in order to not have to download the map every time, I wanted to download it once and then assume that no changed crc means no changed sha512 for that particular server

14:10

but we can have multiple servers hosting the same (mapname, crc) combination with different maps

Why not just get the first crc match fkr those?

because that might get the wrong map

14:10

it allows people to poison other people's downloadedmaps

Storing the sha might too

how so?

14:11

the crc → sha512 mapping is supposed to be per IP

14:11

so a server can't manipulate other servers

14:12

don't spam, @ᶰ°Konͧsti

Server crafts a new map with same crc, you assume sha didnt change old map gets loaded

the server can do that anyway

14:13

send a crc/sha512 that doesn't match what the server has loaded

True

14:14

I guess an ip+crc to sha map should work

ok

14:14

then the next thing

14:14

how should we name the maps?

14:14

mapname_crc_sha512.map?

14:14

mapname_sha512.map

14:14

sha512.map

14:14

I dislike the last one

14:15

and another thing

14:15

I guess we should still verify the CRC on the sha512'd maps?

14:15

just for consistency?

No need though right?

the CRC is still sent by the server so the client could look for mapname_<crc>.map

14:16

or should I also not do that?

mapname_crc_sha.map should work actually

14:17

How do we handle the http downloads though?

14:18

Actually we could do mapname_sha_crc.map and maybe abuse the fact that the crc is appended

I thought that this might be a bad idea

14:19

because then you can't see that veryfunnymapname_usingonlyhexcharshere_crc.map doesn't contain a sha512

14:19

offer both maps.ddnet.tw/mapname_crc_sha.map and maps.ddnet.tw/1.2.3.4/mapname_crc.map?

14:19

for map downloads?

14:19

we can do hardlinks there

14:19

or actually

14:20

maybe maps.ddnet.tw/1.2.3.4/mapname_crc.map redirects to maps.ddnet.tw/mapname_crc_sha.map

@heinrich5991 can mapnames be that long?

@Learath2 what do you mean?

veryfunnymapname_usingonlyhexcharshere_crc.map

ah

somebody good in jquery / javascript ?

[quakenet] <Learath2> I'm pretty decent at ES7 by now

20:15

[quakenet] <Learath2> @NeXus what do you need?

https://stackoverflow.com/questions/50277497/jquery-autocomplete-headline-for-results

JQuery Autocomplete Headline for Results

For my autocomplete I sort my results into 3 sections "title", "company", "tag". I would like to have a headline for each section. In practise I want to add <div class='ui-optionHeader'>Headl...

20:15

Maybe you can help me with this

[quakenet] <Learath2> Well I usually start out by laying out a non functional DOM

this seems more of a jquery question though, you could do some css trickery if that's acceptable for you

20:23

first-child selector to be exact

ah this could work

@NeXus correct way would be to extend _renderMenu btw

20:30

while(items[0]){let title = items[0].option; addHeader(title); while(items[0].option === title) { addItem(items[i]); items.splice(0, 1); }}

20:31

would be a pretty meh way to do it but it'd work

Holy xD where would I put this and I assume addHeader(title); is the function which got my header content ? (edited)

[quakenet] <Learath2> @NeXus instead of extending _renderItem like you are doing there extend _renderMenu

20:34

[quakenet] <Learath2> addHeader and addItem are placeholder functions because idk much jQuery, you should check the docs to see how they insert items

20:35

[quakenet] <Learath2> gist of it is addHeader(title) would add a header with title and addItem(item) would add the autocomplete item item :)

heh

20:56

autocomplete

20:56

that's what I'm trying to do with qt right now

what's so difficult about it? it's just a strstr

it's not that part that I'm trying right now

20:58

it's the rendering part

20:58

hence qt

hmm, how is it any different then rendering something else?

I'm not experienced with qt → stuff takes a while

20:59

if you know how to do it, help would be appreciated

well I never did it before so I don't see how it'd be any harder then rendering sth else

20:59

I'm surely missing sth

nah

21:00

it's probably not harder than putting other widgets on the screen

21:00

but I don't even know how to do that properly

21:00

I want a window that consists of a single line edit box

21:00

haven't managed to do this one yet

21:00

if someone knows devs working with qt, please tell me

[quakenet] <Learath2> heinrich5991: do they not have an irc channel for that?
