03:50<andythenorth>I have no information on the 'Python is slow' problem
03:51<andythenorth>might be easiest to just go to C++?
03:52<@Alberth>safest, at least, and generally accepted
03:53<andythenorth>then we could distribute a cross-platform binary?
03:53<@LordAro>moin
03:53<andythenorth>avoid all the python packaging problems
03:53<@Alberth>computers without default installed python aren't useful anyway :p
03:54<@Alberth>but yeah, just compile it at all relevant platforms

03:57<andythenorth>not sure how maintainability is affected by python vs C++
03:57<@LordAro>needs some profiling, before making assumptions
03:58<andythenorth>I think maintainability is +/-0
03:59<andythenorth>lots of contributors here dislike python
03:59<andythenorth>nml has fallen into a poor maintenance state
03:59<andythenorth>python helps me maintain trivial things like constants, but I can't work with the parser / lexer :P
04:00<@Alberth>LordAro: expression optimizing is done too often, but it's pretty much impossible to say which ones are actually needed
04:00<@Alberth>it can't get much worse than current nml :)
04:00<andythenorth>a spike rewrite to C++? o_O
04:01<andythenorth>pick a subset of features, and make a minimally functional compile?
04:01<@Alberth>could be an option
04:02<@Alberth>just grfid, I bet :p
04:02<@Alberth>maybe town names?

06:11<nielsm>all newgrfs are in place
06:12<nielsm>suspicious... https://0x0.st/zKzj.png
06:14<TrueBrain>hmm .. I forgot that modifying a patch in place is difficult, because it also tracks 'adds' and 'removes'

06:37<TrueBrain>patch files are picky :D
06:37<TrueBrain>if a chunk has no changes, it errors
06:37<TrueBrain>so how can I, in a streaming way, remove additions .. hmm
06:38<TrueBrain>I don't want to complicate my script by tracking chunks :(
06:43<nielsm>gah I wish assert breaks in the VS debugger would take me to the assert call, instead of inside the assert library code

07:07<DorpsGek_II>[OpenTTD/OpenTTD] TrueBrain updated pull request #7397: Backport marked PRs to 1.9 https://git.io/fjJ4C
07:07<TrueBrain>lets see if I did this correctly :D
07:10<TrueBrain>no language errors; so I guess I did :)
07:12<TrueBrain>115 lines of Python
07:12<TrueBrain>I should store this somewhere ..
07:12<nielsm>I guess it's not a catastrophe if the 1.9 lang files end up containing a new string only necessary for 1.10
07:13<TrueBrain>the main issue for me were strings that were modified in 1.10
07:13<TrueBrain>you don't want those in 1.9 :)
07:13<TrueBrain>so I wrote a simple script that ignores any id that is changed in master (from release branch), and ignores those lines in the translations
07:14<TrueBrain>both removal, additions or modification
07:14<TrueBrain>"best effort" :D

07:15<Samu>hi
07:15<TrueBrain>hmm .. how can we poke translators to fix those '35' outdated strings and stuff ..

07:16<TrueBrain>do we normally email them or something?
07:17<TrueBrain>many have not been updated for 1.9, it seems
07:17<TrueBrain>German even is outdated :P
07:19<nielsm>maybe? no idea
07:20<Samu>TrueBrain, I made a small mistake. On the last tick, both DC_TEST and DC_EXEC are run, they both fail on my patch
07:21<Samu>I edited it
07:22<nielsm>I'm amazed the latin translation is among the almost complete ones...
07:22<Samu>as for trying to start multiple AIs in just one command... I don't know how to do that
07:23<Samu>I mean, I know, but I don't think it will work
07:23<Samu>OnTick_Companies never stops being called
07:23<nielsm>Samu: My suggestion for fixing AIs starting correctly "simultaneously" would be to send the next "start AI" command within the execution of the previous
07:39<Samu>how?
07:40<Samu>I'm always worried about OnTick_Companies
07:41<TrueBrain>nielsm: that would work too; I would just add the 'amount of AIs to start' to that command, and loop in there :)
07:41<TrueBrain>just moving of code, basically
07:42<Samu>but OnTick_Companies...
07:42<TrueBrain>nielsm: funny, tail recursion or loop recursion :D
07:42<Samu>uhm, so it starts 10 AIs as 1 command, then next tick it could do the same
07:42<Samu>start 10 more

08:05<Samu>ah bitmask magic
08:06<Samu>i think you mean 15 bits
08:06<Samu>but i see it can work
08:07<nielsm>may as well reserve a full 16 (initially) instead of making some weird odd positions
08:08<Samu>OnTick_Companies will still be queued a second time
08:08<Samu>but fail against the bitmask
08:09<Samu>instead of dozens of commands failing, it's just 1 or so

09:15<Samu>ugly?
09:15<Samu>i dont know about the bitsmask
09:16<Samu>must work on a bitmask thing
09:17<@Alberth>not working mostly
09:18<@Alberth>CCA_NEW_AI | INVALID_COMPANY << 16 is interpreted as (CCA_NEW_AI | INVALID_COMPANY) << 16 rather than the most often intended CCA_NEW_AI | (INVALID_COMPANY << 16)
09:19<nielsm>also you probably should not store data in the command number?
09:19<nielsm>hmm...
09:19<nielsm>oh
09:19<nielsm>I'm misreading
09:19<Samu>INVALID_COMPANY is meant to start AI as spectator
09:19<@peter1138>AI specatator? What?
09:20<Samu>the command is issued by 255
09:20<Samu>it's fine
09:20<@Alberth>AIs like to watch too :p
09:20<Samu>I didn't change that, it's how the command is issued
09:21<Samu>the owner of the command
09:21<@Alberth>that doesn't mean it makes sense :)

10:25<TrueBrain>you are still fixing symptoms .. not the issue
10:26<Samu>:( ok i give up
10:26<Samu>somebody else take over
10:29<@peter1138>ok
10:30<@peter1138>> out
10:30<TrueBrain>you seem to be so focused on the symptoms, that you forget to look at the problem itself. And I think the problem already started with the initial patch that introduced this behaviour
10:30<TrueBrain>the system is not designed to start more than one company in a single tick
10:30<TrueBrain>so there the problem already starts
10:31<TrueBrain>fixing it at the other end of the spectrum only results in lines and lines of code validating if things have changed in the meantime
10:31<TrueBrain>but you have to ask yourself .. why can it queue more AIs than intended?
10:31<TrueBrain>and does that part of the system make sense?
10:32<TrueBrain>as when I look at the code, I wonder if the original patch didn't introduce another issue too: to me it looks like that every tick the system checks if it should start an AI
10:32<TrueBrain>every
10:32<TrueBrain>tick
10:32<TrueBrain>sounds a bit wasteful on the CPU
10:32<TrueBrain>Normally this was only done AT MOST once a game-day
10:33<TrueBrain>which is still iffy, but at least less wrong
10:33<TrueBrain>seems the initial review didn't spotted this
10:33<TrueBrain>specifically, here: https://github.com/OpenTTD/OpenTTD/blob/011257dc8804175dd7d1e839e97e796c0a88aee6/src/company_cmd.cpp#L723
10:34<TrueBrain>if GetStartNextTime is zero, _next_competitor_start is always one, so every tick it runs MaybeStartNewCompany .. every tick
10:34<TrueBrain>I think there it already went wrong
10:34<TrueBrain>and the rest just is an escalation of that issue

11:13<Samu>:(
11:14<Samu>checking every tick was so it could start AIs immediately
11:14<Samu>it was the whole point of the patch
11:14<TrueBrain>so for the whole of the rest of the game, you checking something every tick, just so you could start them at the beginning
11:14<TrueBrain>can you see there is some logic error in there?
11:15<TrueBrain>and as such, my suspicion is that if you fix the root cause (checking every tick till the end of time if there might be a reason to start an AI), the symptom you are currently fixing goes away too
11:15<Samu>maybe I can now change that part back to checking daily, since it can now start multiple AIs in 1 command

12:25<TrueBrain>"/usr/bin/rpmbuild can't handle paths with spaces, use a build directory without spaces for building RPMs."
12:25<TrueBrain>LOL!
12:26<@LordAro>lol.
12:28<andythenorth>LOL1!!!!!111!!
12:29<@peter1138>Oh dear.
12:29<Eddi|zuHause>... at least they check and don't silently fail? :p
12:30<@peter1138>Well the thing about checking if you need to start a tick is that traditionally it was with a delay of a year or so. But it still checked every tick.
12:31<andythenorth>let's delete something
12:31<TrueBrain>okay, changing build directory with cmake is really easy .. which makes me happy :)
12:33<Samu>i'm reworking MaybeStartNewCompany
12:35<Samu>the delay was 74 ticks
12:36<@LordAro>hmm
12:36<@LordAro>why did instant starting AIs get included in the game?
12:36<@LordAro>wouldn't it be more appropriate for an admin console thing?
12:37<Samu>beucase it's a new feature
12:37<Samu>and I like it :p
12:37<Samu>hehehe
12:38<Samu>j/k
12:39<@peter1138>LordAro, well, revert it all, and then the problem is solved :p
12:39<@LordAro>peter1138: well indeed
12:39<andythenorth>revert
12:40<@peter1138>Hmm, why are news items not saved?
12:42<_dp_>peter1138, who needs that spam :p
12:43<@peter1138>Dunno, just seems like missing game-state.

12:50<TrueBrain>Samu: a lot better, in my opinion. But to me it reads you are slipping in additional changes :)
12:50<TrueBrain>the src/openttd.cpp changes seems unrelated to the fix
12:50<Samu>it is, otherwise it would have to wait 1 day
12:51<Samu>or actually... wait
12:51<Samu>that is wrong :(|
12:51<Samu>damn... i fail
12:52<TrueBrain>and GetStartNextTime() for sure needs some love. 'skip_counter' is not very verbose, and comments in that function are now wrong :)
12:52<@peter1138>Why did I buy more snacks? I have tons of snacks :/
12:52<@peter1138>Brexit-snack-stockpiling?
12:52<TrueBrain>seems more you mean 'index' or something, instead of 'skip_counter'
12:52<TrueBrain>peter1138: yes
12:53<Samu>_next_competitor_start = max(DAY_TICKS, AI::GetStartNextTime() * DAY_TICKS); this is wrong, halp
12:53<TrueBrain>also, because you are inviting us to a party are your house
12:53<Samu>or is it right?
12:53<+glx>hmm TrueBrain, seems you drop my timestamp commit
12:53<@peter1138>TrueBrain, go for it.
12:53<TrueBrain>glx: yes, I did
12:53<TrueBrain>glx: it failed horribly here
12:53<TrueBrain>on a clean build, it refused to work
12:53<TrueBrain>so I wanted to ask you if you knew what was going on
12:54<TrueBrain>well, I did not mean to drop your patch as such
12:54<Samu>max(74, 0 *74) = 74
12:54<TrueBrain>but ... my push did :P
12:54<TrueBrain>glx: I tried another approach to fix your itch; does that also work?
12:54<Samu>getstartnexttime will still be 74 ticks
12:54<TrueBrain>https://github.com/OpenTTD/OpenTTD/pull/7270/commits/a8929d0691ab7b1d3a135a0cfebf6fd457452a4d <- glx
12:54<TrueBrain>(and sorry, I wanted to push to another branch of mine, but I forgot :( )
12:55<+glx>for baseset your approach is ok as they are not used later in build
12:55<Samu>but then --_next_competitor_start means MaybeStartNewCompany() will never run
12:55<TrueBrain>glx: I couldn't find a way to break the other 2 you changed
12:56<TrueBrain>I now got what you meant with the configure_file() btw
12:56<TrueBrain>are there other places that break?
12:56<+glx>easy, build, touch window_type.h and it will regenerate script_window.hpp everytime
12:57<TrueBrain>owh, in your other branch?
12:57<+glx>in cmake branch
12:57<TrueBrain>hmm .. let me try; as I don't get what your commit fixed for that?
12:58<TrueBrain>anyway, what broke with your commit, was that it kept telling me it couldn't find table/strings.h or something, in the dependency
12:58<+glx>oh forget it that's in my api branch :)
12:58<TrueBrain>it only worked if I manually touched that file in existence
12:58<Samu>nevermind, it's correct apparently, I'm stupid
12:58<TrueBrain>glx: pfew, was afraid I was going mad :P :D
12:58<+glx>in cmake branch touch any .ini for settings
12:58<+glx>or english.txt
12:59<TrueBrain>testing ...
12:59<@peter1138>How do you run your Manley-Morel DMUs? As is, or with extra carriages?
12:59<nielsm>occasionally adding up to two extra cars
13:00<+glx>it will the "regenerate" strings.h and settings.h everytime
13:00<DorpsGek_II>[OpenTTD/OpenTTD] TrueBrain updated pull request #7270: Introduce CMake (and removing all other project-related code) https://git.io/fhbqc
13:00<+glx>*then
13:00<TrueBrain>glx: as I came to the realization when I was debugging your commit, that it feels a bit off; keeping another file to avoid Makefile doing the wrong thing
13:00<TrueBrain>what do you think about the commit above; can we also live with that? (touching the files)
13:01<+glx>will then rebuild a lot for a non real change
13:01<TrueBrain>but only once
13:01<+glx>will be a pain for api ;)
13:02<supermop_Home>yo
13:02<TrueBrain>it is the same as when you touch CMakeLists.txt, it also triggers a recompile for some files, which might not have been needed
13:02<TrueBrain>what is the usecase for those files to change glx?
13:02<supermop_Home>apparently I had left the window in the room open slightly all winter and just noticed it now
13:03<+glx>you can change english.txt just to fix a typo without needing to rebuild all files using strings.h
13:03<TrueBrain>glx: I expected settingsgen to always touch the output file .. I guess it does not :)
13:03<TrueBrain>glx: good usecase
13:04<TrueBrain>the issue is, I guess, that we are fighting against how 'make' expects things to work
13:04<TrueBrain>owh, there was btw a real bug in your macros glx, at least I think: if the dependency in add_target didn't have byproduct set, it was never added again
13:05<TrueBrain>so it could miss dependencies, from what I could tell
13:05<+glx>not needed
13:05<+glx>byproducts is mainly a ninja thing
13:05<TrueBrain>yes, dependencies is not :)
13:05<Samu> /* Find the first company which doesn't exist yet, but skip some */
13:05<TrueBrain>https://github.com/OpenTTD/OpenTTD/commit/eb8f74c77e338fabb99f8e191aab6c5b04367729#diff-329abb7dc9357c4e0885581a0509b09bR98 <- that IF is missing an ELSE, from what I can tell :)
13:06<Samu>good comment? :p
13:06<TrueBrain>Samu: no
13:07<+glx>the original depends file is added before the if
13:07<@peter1138>Comments should really explain why. The what is covered by the code.
13:07<TrueBrain>glx: gatcha!
13:07<TrueBrain>glx: it is really hard to read, as you notice :D
13:08<+glx>yes cmake language doesn't always help
13:08<TrueBrain>glx: I also could not figure out what all the ;:::, :::, and :::; was about
13:08<andythenorth>AIs are too hard to code
13:08<andythenorth>and need to be improved
13:08<@peter1138>Yes ;)
13:08<andythenorth>they're unintuitive
13:08<@peter1138>I hope in the future...
13:08<andythenorth>and hard to figure out
13:08<+glx>I replace the keyword with ::: so each command stay separated
13:08<andythenorth>are AIs hard to code?
13:09<@peter1138>Yes, but that's the AI part, not the API part.
13:09<TrueBrain>glx: blaming CMake is easy; but what I notice that newlines, some comments, etc, really help :)
13:09<@peter1138>We delegated them to scripts for a reason :)
13:09<+glx>because cmake_parse_arguments merges all matching keywords into a single list
13:10<TrueBrain>glx: now THAT is a useful comment to add ;) As it explains the "why" more than the "what" :)
13:10<+glx>so 3 commands end up in only one
13:11<TrueBrain>we really have to work in the CMake files to not add comments telling what we can read in the code below, but WHY we added those lines :D
13:11<TrueBrain>(I noticed that with some of my own code too)
13:11<TrueBrain>anyway, please check if you can fix your patch breaking on an clean build directory, would be nice :D
13:13<Samu>maybe reserved_counter?

13:15<Samu>it's not really an 'index'

13:47<@peter1138>(uint)1 -> 1U
13:47<Samu>1U ok
13:47<Samu>but p2 or 1U?
13:49<Samu>i'm inclined towards uint num_to_start = max(1U, GB(p2, 0, 4));
13:49<@peter1138>Hmm
13:49<@peter1138>Are you saying that I can't start up multiple AIs instantly during a game, now?
13:49<@peter1138>(By increasing max competitors)
13:50<Samu>no, p2 in some places is still 0
13:50<Samu>start 0 AIs makes not much sense
13:50<@peter1138>I'm refering to _next_competitor_start and the removal of the loop.
13:50<@peter1138>I guess it doesn't matter to much. DAY_TICKS is quite short.
13:50<@peter1138>*too
13:51<Samu>p2 is meant to be the number of ais to start

18:42<Samu>i think im missing a check, now that i closely look at it
18:43<Eddi|zuHause>i'm fairly sure && is a sequence point
18:43<Eddi|zuHause>but it is definitely a dangerous field to step in
18:47<_dp_>yeah, while(--x) is borderline acceptable imo but not that
18:48<Eddi|zuHause>there's no reeal reason why it couldn't be a separate statement
18:50<Eddi|zuHause>also "(uint)_settings_game.difficulty.max_no_competitors - num_to_start_for > 0" is probably better expressed as "num_to_start_for < (uint)_settings_game.difficulty.max_no_competitors"
18:57<Eddi|zuHause>on a separate note, why is it checking for _settings_client.network.max_companies? i would have taken that as max human companies...
18:57<Eddi|zuHause>so people can set those things separately

18:58<Samu>it was already there
18:58<Samu>I kept the same functionality
18:59<Samu>my while is missing a check, speaking of which, that one
19:00<Samu> } while ((!_networking || num_to_start < _settings_client.network.max_companies) &&
19:00<Samu> num_to_start < (uint)_settings_game.difficulty.max_no_competitors && AI::GetStartNextTime(num_to_start) == 0);

19:01<Samu>https://paste.openttdcoop.org/pqmxwmsfy
19:02<milek7>don't try to force everything into while condition
19:05<Samu>do you think AI::GetStartNextTime(num_to_start) is sufficient?

19:09<Samu>I'm starting to think that simple check is sufficient
19:10<Samu>no need for "redundancy" or so
19:13<@peter1138>KISS.
19:14<drac_boy>I thought the same thing too peter ;)
19:17<Samu>https://paste.openttdcoop.org/pd6hcz4nz
19:17<Samu>do while versus for
19:17<Samu>i think it's gonna assert, i fail at fors
19:18<Samu>boom, asserted
19:18<Eddi|zuHause>why are you checking the same condition twice, once in the while and again in the if break?
19:20<Samu>assert(1 == 0); yep... the for one is wrong
19:20<Eddi|zuHause>because the GetStartNextTime check is once before the ++ and once after the ++
19:23<Eddi|zuHause>you effectively moved the while-check to the beginning of the loop, not the end
19:26<Samu>lol at me, I thought for loops were supposed to be easier than do while loops
19:26<Samu>I'm failing miserably
19:29<Samu>uhm nop
19:30<Samu>loops like now the error is in do while
19:30<Samu>damn me
19:37<Samu>no, it's correct
19:37<Eddi|zuHause>for loops are easy. "for (a; b; c) { d }" is equivalent to "a; while (b) { d; c }"
19:38<Eddi|zuHause>(there are minor semantic differences in various languages)
19:39<_dp_>Eddi|zuHause, try that with do...while :p
19:39<Eddi|zuHause>i don't know why it's a do..while in the first place
19:40<Samu>for loop is still wrong
19:40<Eddi|zuHause>or what the aim of the exercise is
19:40<Samu>just retested the do while loop
19:40<Samu>and it's correct
19:40<Samu>damn me
19:41<Samu>https://paste.openttdcoop.org/pyqgli0qr i have this atm
19:41<Samu>do while is working correctly. for is not matching :(
19:44<Samu>while loop could even be simplified again
19:44<Samu> } while (AI::GetStartNextTime(++num_to_start) == 0);
19:44<Samu>and remove num_to_start++; line

I am sure you can make something more readable from it. but don't focus on the do/while on it's own.. think what you want it to do, and do it in the most clean way you can!
20:21<Samu>okay
20:23<@peter1138>Hmm, maybe it is cleaner to keep the waterclass-for-tree-tiles change.

22:06<@peter1138>Turns out that doing the savegame conversion and keeping the data duplication is cleaner than reverting and explicitly checking for trees on coasts.
22:06<@peter1138>Hmm.
22:14<Samu>why can't I do something that is so simple...
22:23<Eddi|zuHause>or we scrap the pseudo-water-classes and recalculate it for more tiles?
22:23<Eddi|zuHause>like for industries and stuff?
22:24<@peter1138>Eddi|zuHause, possible but makes everything more complex.
22:24<Eddi|zuHause>yeah.
22:24<@peter1138>For the sake of 3 bits which are already allocate.d
22:24<Eddi|zuHause>exactly
22:25<@peter1138>For tree tiles it's very easily calculated, I'm not sure about the others.
22:25<Eddi|zuHause>this is more a "maybe we should have designed it differently in the first place, but for now it works" kind of thing

22:49<@peter1138>Hmm, this may call for... minor version :p
22:50<@peter1138>Really it calls for _sl_version <= major, but we don't have that function.
22:53<Eddi|zuHause>iirc there was some trickery done in some minor releases to have savegame conversion stuff without breaking the forward compatibility
22:53<Eddi|zuHause>i have no clue what that was, though
22:54<@peter1138>If we check against sub version 1, then it basically becomes a <= test.
22:54<@peter1138>But it's not entirely clear :/
22:55<@peter1138>Probably best to add a new function.
22:56<Eddi|zuHause>i don't know why we have a minor version when we're not allowed to use it
22:57<@peter1138>It's only there because it's needed for old savegame conversion.
22:58<@peter1138>It's read-only, not written to the save.
