03:24 hmmmm not a very minetesty day
03:27 * est31 is trying to apply the RFC test vectors to the srp implementation
03:28 hmmmm sweet
03:28 est31 but struggling with c heredocs for binary data
03:28 est31 "heredocs"
03:28 est31 I declare static const srp_5054_salt[4] = { 0xBEB25379UL
03:28 est31 , [...] };
03:29 est31 when I print it again, I get 7953B2B...
03:29 est31 which is weird
03:34 * est31 tries the shorter 0x variant
03:38 est31 now it works
03:43 Hunterz joined #minetest-dev
04:37 OldCoder joined #minetest-dev
04:54 est31 and now I can confirm it all works
05:01 hmmmm heh
05:01 hmmmm what was the problem with the constant?
05:08 est31 no idea
05:08 est31 using 0xBE, 0xB2, 0x53, works
05:08 est31 but not the UL method
05:10 hmmmm endianness?
05:12 est31 may be
05:14 est31 https://github.com/est31/csrp-gmp/commit/​a65c9226d4002e53c8720ce39246b2b540526c62
05:15 hmmmm ah that's your own
05:15 est31 yup
05:15 hmmmm so you basically ended up forking csrp
05:15 est31 yes
05:15 est31 when you port it you have to
05:15 hmmmm i think the world needed this, after seeing the sheer lack of options
05:16 hmmmm just make sure you stay up on it :)  this might become your 'thing'
05:16 est31 :)
05:16 hmmmm make sure you write unit tests for it too at some point
05:16 est31 that commit is basically adding unit tests
05:16 hmmmm oh derrp
05:17 hmmmm I'm going to slap that test into the new minetest unit test framework
05:17 est31 great
05:18 hmmmm there was a point at which celeron decided to say fuckit and not add any new unit tests and nobody else wrote them to begin with
05:18 est31 but not before #2620 gets merged that adds the file
05:18 ShadowBot https://github.com/minetest/minetest/issues/2620 -- SRP based login by est31
05:18 hmmmm yeah sure
05:18 hmmmm obviously
05:18 hmmmm :)
05:19 hmmmm btw 2620 is completely ready for review?  it's not a WIP at all anymore?
05:19 est31 there are still points
05:19 hmmmm ahh okay
05:19 est31 see commit message https://github.com/est31/minetest/commit/​bb074a1237caf4e97740f0f74e9c6ff506528c56
05:19 hmmmm keep up the good work though :)

07:44 hmmmm well uh oh
07:45 hmmmm pretty nasty combination with unsigned script execution + UDP
07:46 hmmmm actually no nevermind, you don't need to hijack the session at all
07:46 hmmmm a man in the middle could easily modify the script being sent to the client to be executed
07:49 hmmmm i have concerns about media transfer being MITMed on joining a server.  when client side scripting gets added, the man in the middle could trivially modify the script and possibly use it for bad things like javascript on websites already is
07:49 hmmmm like for example advertisement injection
07:51 hmmmm getting network encryption should be a priority after SRP is added
07:51 OldCoder joined #minetest-dev
07:54 Calinou who is going to inject stuff just for ads?
07:55 hmmmm i guess minetest has a significantly smaller marketshare than javascript and http but eh :)
07:56 hmmmm what if some asshole MITMed traffic and changed all the textures being sent from the server to something like a giant cock
07:56 hmmmm that would be hilarious and frightening at the same time
07:57 jin_xi yay

09:06 Calinou yeah, pron/epilepsy pranks are more dangerous
09:06 Calinou I had that in mind too
09:06 Calinou but a server can do this already
09:06 Calinou use a server texture pack with inappropriate stuff
09:06 Calinou I'm surprised I haven't ever seen this in 3.5 years

13:37 nrzkt i found an long time unused variable in client.h Client::m_active_blocks (this variable is in environment.h). I will remove it in the next 5 minutes

16:39 est31 perhaps still group them but have a smaller distance?

17:06 est31 OMG chat is really sent over the network as wstring?
17:06 est31 where was that exploding shit video again?
17:07 Calinou we could encrypt chat :P
17:07 Calinou Xonotic did it, AES-encrypted game
17:07 Calinou but nearly no one uses it :P
17:07 Calinou not to mention the legal issues
17:07 est31 legal?
17:08 est31 is it illegal to encrypt?
17:08 Calinou in some countries, yes
17:08 est31 I live in central europe
17:09 est31 before they run a server people have to check whether its legal to run it or not
17:09 est31 not my fault if they still do if its illegal
17:09 est31 this is the no warranty part of the GPL
17:10 Calinou Fedora and such would probably disable support
17:10 Calinou but then you wouldn't be able to connect to servers which require encryption
17:10 est31 is https disabled on fedora too?
17:12 Calinou no
17:14 est31 so whats the issue then?
17:14 * Calinou shrugs

17:57 Warr1024 hey, did anyone ever merge #2589?
17:57 ShadowBot https://github.com/minetest/minetest/issues/2589 -- Fix fast leaves when texture_clean_transparent is enabled. by Warr1024
18:01 est31 Warr1024, sorry for not reviewing, I'll have a look after I have read through my srp patch
18:06 Warr1024 thanks
18:14 OldCoder joined #minetest-dev
18:16 Wayward_Tab joined #minetest-dev
18:21 est31 Warr1024, what are fast leaves?
18:26 est31 pushing in 15 minutes: https://github.com/est31/minetest/commit/​e3764410d3934726c47b8a5b2b347678c039a0e4
18:27 sfan5 est31: looks good
18:27 Wayward_Tab joined #minetest-dev
18:27 est31 problem was: obstructed view
18:28 est31 pushed
18:36 est31 Warr1024, I can't reproduce the bug, could you post screenshots or how to reproduce?
18:39 Warr1024 est: if you have texture_clean_transparent = true and fast leaves, you'll see all-green trees instead of the intended green leaves with black gaps between
18:39 Warr1024 with the patch, it should display as intended
18:39 Warr1024 there shoudl be a bug report somewhere...
18:39 est31 Warr1024, fast leaves is when you don't check the "fancy leaves" checkbox?
18:39 Calinou yeah
18:40 Warr1024 yes
18:40 est31 Thats what I tried, and I can't reproduce
18:40 Warr1024 ... I can't find the bug report...
18:42 Warr1024 guess I'll have to build the unpatched client and try to repro
18:42 Warr1024 I wonder if somebody fixed this already and didn't close teh pull?
18:42 est31 possible
18:43 est31 but doesnt look like that
18:47 kilbith est31, i can confirm that but that "blend of leaves" looks better than the leaves patterns + black background
18:47 kilbith i'd say it's a positive bug
18:48 Warr1024 it's actually a bug also because of the potential to affect other non-leaves textures unexpected ways
18:48 kilbith right
18:49 cib0 joined #minetest-dev
18:50 Warr1024 posted the screenes
18:51 Warr1024 the problem is that the clean_transparent filter is cleaning up the transparent areas BEFORE they're flattened by [noalpha
18:51 Warr1024 the patch corrects the order
