00:03:53  <Eddi|zuHause> LordAro: i was just trying to sort out the capitalisation and then i drew a complete blank on how capitalisation is meant to work...
00:04:52  <Eddi|zuHause> would be easier if someone else did this, my brain is for some weird reason not able to do this
00:08:17  <Eddi|zuHause> gonna --abort this, makes no sense like this

00:59:21  <Samu> wow, opf search method is really retarded
00:59:56  <Samu> without all the randoms choices, it just go straight until it finds an obstacle
01:00:03  <Samu> then it makes a turn
01:00:11  <Samu> usually turns back
01:02:09  <Samu> bird distance isn't used to help it make better choices
01:02:14  <Samu> why
01:02:56  <Samu> im no pathfinder expert
01:03:05  <Samu> but it's weird
01:05:39  *** Flygon has joined #openttd
01:09:16  <peter1138> It's designed to be low CPU usage.
01:16:02  *** Smedles_ has joined #openttd
01:18:26  <Samu> oh? and then it ends up being the most intensive
01:19:12  *** Smedles has quit IRC
01:21:40  <peter1138> How so?
01:21:52  <Samu> i guess the random choices makes it look "smarter"
01:22:11  <peter1138> They make it more likely to get there, heh.
01:22:28  <Samu> on my 5000 ship testing, OPF is too slow
01:22:50  <Samu> compared with the other 2
01:23:31  <Samu> but the test uses many buoys, so it could influence results

01:38:06  <Samu> just managed to decrease the stall from 14 seconds to 5 seconds
01:38:14  <Samu> for opf
01:38:45  <Samu> that means, npf is the worst when mass sending 5000 ships to depot
01:39:22  <Samu> also with 14 seconds
01:40:46  <Samu> why is this a DoCommand, it tests before executing, so basically, it's 10000 ships
01:41:00  <Samu> does the same work twice
01:42:11  <Samu> @calc 23.656 - 9.015
01:42:11  <DorpsGek> Samu: 14.641
01:42:23  <Samu> npf still stalls for 14 seconds
01:43:51  <Samu> @calc 30.156 - 25.421
01:43:51  <DorpsGek> Samu: 4.735
01:44:07  <Samu> opf stalls for ~5 seconds
01:45:18  <Samu> @calc 31.906 - 45.406
01:45:18  <DorpsGek> Samu: -13.5
01:45:32  <Samu> @calc 31.906 - 34.406
01:45:32  <DorpsGek> Samu: -2.5
01:45:48  <Samu> 2.5 secs for yapf, the king
01:47:56  *** triolus has joined #openttd
01:48:37  <Samu> mass sending 5000 ships to depot results:
01:48:53  <Samu> opf - 4.7 secs
01:48:59  <Samu> npf - 14,6 secs
01:49:04  <Samu> yapf - 2,5 secs
01:49:47  <Samu> must investigate what's so bad about npf for such a long stall
01:57:33  <peter1138> Did you investigate the underlying algorithms behind OPF, NPF and YAPF?
01:59:28  <Samu> in ship_cmd.cpp?
01:59:50  *** triolus has quit IRC
02:00:20  <peter1138> No, in the pathfinding code, heh.
02:00:31  <peter1138> Are you aware that NPF and YAPF are basically the same pathfinding algorithm?
02:00:41  <peter1138> OPF isn't.
02:00:57  <Samu> that's even stranger
02:01:17  <glx> NPF and YAPF are implementations of A*
02:04:54  <Samu> i dont know how to properly time a single search
02:06:34  <peter1138> NPF is a simple literal approach to the algorithm.
02:07:07  <peter1138> YAPF is heavily optimized by using C++ templating and implementing a cache.
02:07:49  <peter1138> So, yeah, YAPF is faster than NPF... by design.
02:08:38  <Samu> what does the cache do?
02:08:47  <peter1138> What does a cache normally do?
02:09:08  <Samu> but in this case, feels like cache isn't doing anything yet
02:09:15  <Samu> or is it?
02:26:03  <Samu> there is no cache for ships, or i dont understand whether it's working

08:01:33  *** andythenorth has joined #openttd
08:02:00  <andythenorth> Eddi|zuHause: I have a custom python sort challenge
08:02:19  <andythenorth> current implementation is "sorted(wagon_consists, key=lambda wagon_consist: wagon_consist.subtype)"
08:02:38  <andythenorth> subtypes are 'A', 'B', 'C', or 'U'
08:03:08  <andythenorth> I want sort rank to be 'U', 'A', 'B', 'C'
08:03:15  <andythenorth> I thought of at least two bad ways to do it
08:03:55  <andythenorth> but presumably sort can be given a custom comparison, such that U < A, U < B, U < C, and A B C remain lexical w.r.t each other

14:04:43  <Eddi|zuHause> andythenorth: depends how "exdentable" you need it, but as a start how about "sorted(wagon_consists, key=lambda wagon_consist: {"U": 1, "A": 2, "B": 3, "C": 4}[wagon_consist.subtype])"
14:05:10  <andythenorth> Eddi|zuHause: looks good I'll try
14:05:44  <Eddi|zuHause> you could also fiddle around with rexex
14:07:03  <Eddi|zuHause> or you could rename the subtypes so they are lexical ordering to begin with
14:07:38  <andythenorth> that was my crude solution
14:07:45  <andythenorth> but yours works, and is highly readable
14:08:28  <andythenorth> thanks

14:58:44  <Samu> hi
15:01:11  <Samu> how do I measure the time a code part takes to complete?
15:02:11  <Samu> need to investigate why npf stalls for too long
15:03:12  <Samu> want to know where exactly the slowdown comes from
15:05:49  <LordAro> Samu: the thing you want to google is "profiling"
15:05:58  <LordAro> and probably add "visual studio"
15:09:26  <Samu> diagnostic tools?
15:17:19  <milek7> i use gperftools
15:18:33  <nielsm> visual studio community should have microsoft's profiler built in
15:18:50  <nielsm> just keep in mind it can take a LOT of memory/storage to capture a profiling run

17:03:28  <peter1138> nielsm, nice.
17:03:41  <nielsm> Samu: means it spends a lot of time zeroing memory, I guess
17:05:17  <nielsm> reversing little programs like this is an oddly fun kind of puzzle
17:06:09  <nielsm> taking guesses at what some things are/do, then try building a skeleton program for that, then deriving some more meaning from the original, blindly re-implementing code you don't understand, and then slowly getting to an understanding
17:06:18  <nielsm> I'm sure you can get better at it with practice :)
17:07:08  <peter1138> Surely you just try something once, realise it doesn't work, keeping try, still doesn't work, then give up and move on to something else?
17:07:41  *** GroovyNoodle has quit IRC
17:09:02  <Samu> in debug mode these times are skewed

17:31:34  <Samu> top - npf, middle - opf, bottom - yapf
17:31:52  <Samu> ah, memset was only shown on debug mode, i guess
17:32:44  <Samu> i'm still unsure what numbers are important

17:36:11  <Eddi|zuHause> (that's one of the largest news magazines and one of the largest news websites in germany)
17:37:08  <Samu> the slower part of NPF is BinaryHeap::Delete and Has
17:37:12  <Samu> Hash::FindNode

17:39:01  <Eddi|zuHause>
17:42:43  <Samu> the slow part is queue.cpp, I never touched this file
17:42:52  <Samu> dont even know for sure what's doing
17:43:15  <nielsm> it's a data structure for a priority queue, I believe
17:43:28  <Samu> it has BinaryHeap and Hash
17:43:30  *** Wormnest has quit IRC
17:44:15  <Samu> BinaryHeap sounds familiar, I had that thing on my AI, and switched to Fibonacci
17:44:17  <nielsm> and it's likely the part that takes up the most time because stuffing elements into a queue and taking them out again might be the basis of the algorithm
17:45:07  <Samu> now, i dunno anything about the hash
17:46:20  <Samu> There's nothing I can do here then :(
17:48:48  <Samu>  * Deletes the item from the queue. priority should be specified if
17:48:48  <Samu>  * known, which speeds up the deleting for some queue's. Should be -1
17:48:48  <Samu>  * if not known.
17:49:01  <Samu> that's a funny comment, it ends being the slowest part of NPF
17:49:21  <Samu> bool BinaryHeap::Delete(void *item, int priority)
17:49:30  <Samu> ok, enough of this
17:49:36  <peter1138> Don't bother trying to optimise NPF. YAPF exists for a reason.
17:50:03  <Samu> yapf was the fastest

18:41:51  <andythenorth> I went onto LinkedIn
18:41:57  *** Progman has joined #openttd
18:42:28  <andythenorth> then...I messaged Yexo in it
18:43:00  <LordAro> :o

18:43:22  <LordAro> andythenorth: any particular purpose?

18:44:09  <nnyby> haha same i feel
18:47:09  <LordAro> andythenorth: excellent
18:48:42  <Samu> i have some patches here that i'm scared to PR
18:48:56  <Samu> because I know already they're not gonna be accepted
18:49:03  <Samu> but they are done :(
18:50:25  <peter1138> Yo?
18:50:56  <Samu>
18:51:05  <Samu> for example that one
18:52:44  <andythenorth> peter1138: open source clone of Chocks Away?  I could ask him if he wants to help....
18:53:19  <nielsm> some of the code this compiler has generated is completely baffling... "and     al, 0FFh"
18:53:19  <peter1138> Requires me to sign in.
18:53:32  <nielsm> al is a byte register, and'ing it with FFh is a no-op
18:53:41  <peter1138> nielsm, sets CPU registers though, no?
18:53:58  <nielsm> touching al should not touch ah
18:54:01  <peter1138> Dunno though.
18:54:06  <andythenorth> nielsm: LinkedIn such very evil
18:54:07  <nielsm> though it should clear the top 16 bits of eax
18:54:20  * andythenorth wonders if MS will merge LinkedIn and github
18:54:26  <andythenorth> it's the obvious step
18:54:46  <nielsm> GitIn
18:55:00  <peter1138> nielsm, I mean the FLAGS register. I dunno if it does.
18:55:05  <andythenorth> free recruiter spam with every PR
18:55:21  <nielsm> yeah no, the next thing it does it pushing ax to set up a function call

18:57:11  <Samu> theres microphone support on openttd now=
18:58:01  <Samu> something from X Audio?
18:58:51  <nielsm> dwfreed: honestly I should just stop being shocked that a C compiler from 1994 (or earlier) generates bad code
19:00:07  <nielsm> Samu: no, xaudio is only used for sound out, as an alternative to dsound on windows

19:29:22  <andythenorth> branch -D generally
19:29:29  <andythenorth> but read the scm pages first
19:29:31  <Samu> i was only experimenting
19:29:38  <andythenorth>
19:29:58  <Samu> now i see some of my old deleted branches still listed as "deleted"
19:30:26  <andythenorth> dunno
19:30:30  <andythenorth> :)
19:38:28  <Samu> doesn't really delete my stuff
19:38:52  <andythenorth> branch -D, force push
19:38:55  <andythenorth> usually considered rude
19:38:56  <andythenorth> but eh
19:38:57  <Samu> it leaves it hiden somewhere, allowing me to restore later
19:39:26  <Samu> it's stuff already implemented, so i dont need to keep these branches
19:40:12  <Samu> Team Explorer on visual studio apparently deletes them for good
19:43:00  <Samu> good, they're gone

19:54:23  <DorpsGek_II> [OpenTTD/OpenTTD] LordAro approved pull request #6784: Ship cpu hog workaround for #6145
19:55:16  <LordAro> Samu: in practice, you only need to rebase when something else interferes with something that you've done
19:55:37  <Samu> wow there's more ppl working on ship stuff
19:55:55  <Samu> ah, i see
19:56:15  <LordAro> i.e. if misc_gui.cpp has been modified in master, and you've been fiddling with pathfinders, they're unlikely to interfere
19:56:52  <LordAro> but these interactions aren't easy to see in advance, so it's best practice to rebase often

19:57:43  <Samu> those changes look scary as heck

19:57:58  *** GroovyNoodle has joined #openttd
19:58:44  <LordAro> as an example, the above will definitely interfere with the stuff you've been playing with :)
19:59:04  <glx> and you also rebase if you need to add something to the PR, but rebase just to rebase is useless
19:59:51  <Samu> if (v->dest_tile == 0 || DistanceManhattan(tile, v->dest_tile) > SHIP_MAX_ORDER_DISTANCE + 5) { using distance manhattan like this is gonna be a disaster waiting to happen, but let me test
20:00:24  <glx> "add something" as a new commit, or an modified commit
20:00:32  <LordAro> Samu: why do you think so?
20:00:41  <LordAro> distance manhattan is a very simple calculation
20:00:58  <Samu> the pathfinder may find a path that makes the ship move the opposite direction
20:01:15  <glx> yes if it's shorter
20:01:17  <Samu> if the distancemanhattan check triggers.... rip ship
20:03:22  <LordAro> it was discussed in the PR (or possibly here) - you already can't set orders further than SHIP_MAX_ORDER_DISTANCE apart, so it shouldn't make any difference
20:04:13  <LordAro> but you're welcome to test these things
20:04:29  <LordAro> (or indeed, comment on PRs)
20:04:59  <andythenorth> but the video here is awesome
20:05:54  <LordAro> hehe
20:06:20  <LordAro> i am actually curious what would happen if you try to send to depot when the nearest depot is > 130 tiles away
20:07:07  <andythenorth> easy to test
20:07:37  <LordAro> *hopefully* it will say "cannot find depot", rather than just stopping the ship

21:36:57  <glx> something like

21:55:34  <Samu> just tested
21:55:41  <Samu> it's not good
21:56:36  <Samu> distance manhattan is the reason why pathfinders get lost
21:57:00  <Samu> this ship i'm testing is currently not invoking the pathfinder
21:57:12  <Samu> it is a miracle it still finds its way to destination
21:58:00  <Samu> goes forward, reaches the map border, makes some turns, reaches the other map border, and it finally gets moving in a direction that will make the pathfinder be invoked again
21:58:22  <nielsm> someone should be using more buoys
21:58:24  <Samu> then it gets to its destination, after doing some weird turns
21:59:45  <LordAro> mm
22:00:17  <Samu> i'm not sure, it doesn't feel right
22:00:50  <Samu> but yeah, buoys being the solution for ships :(
22:04:16  <Samu> buoys could be abused :( but i kind of like the idea of buoys being a guidance for pathfinders
22:06:04  <Samu> gonna try making buoys a negative penalty, essentially turning them into a bonus
22:07:08  <LordAro> that's unlikely to improve pathfinder performance, if that's what you're trying
22:08:46  <Samu> let me test
22:11:52  <Samu> oh, it's a npf exclusive feature
22:11:55  <Samu> very well
22:12:04  <Samu> i thought yapf had it
22:13:48  <Samu> doesn't let me add negative values
22:13:50  <Samu> boo
22:14:28  <LordAro> heh
22:15:43  <Samu> cost -=; // A small /*penalty */ bonus for going over buoys
22:15:52  <Samu> let's see
22:16:04  <nielsm> oh, I think I'm almost code complete for the adlib music decoder, except for a bunch of static tables I need to copy over
22:17:42  <Samu> doesn't work
22:18:21  <Samu> aystar asserts warning me that new_g > 0 failed
22:18:36  <milek7> hm
22:18:40  <milek7> i commited git merge
22:18:42  <milek7> and now i want to undo it and perform conflict resolution of single file again
22:20:11  <milek7> but reset will obviously throw away all changes
22:20:36  <LordAro> rebase!
22:20:48  <Eddi|zuHause> yeah, modifying commits is rebase
22:20:52  <LordAro> alternatively, reset --soft
22:21:07  <LordAro> if the commit is still local
22:21:13  <Samu> i use the recycle bin
22:21:18  <Samu> and clone again
22:21:22  <Samu> works everytime
22:21:30  <LordAro> good ol' Samu
22:21:57  <Samu> if i want to go back to stuff I had, i take it back from recycle bin
22:22:47  <milek7> ok, maybe reset to before merge, start merge, checkout good files from new commit, resolve bad file and commit
22:23:30  <LordAro> milek7: that's probably what i'd do
22:28:31  <Eddi|zuHause> you don't need reset if you rebase
22:29:05  <Eddi|zuHause> just carefully consider what the target of the rebase is
22:29:07  <LordAro> Eddi|zuHause: except in this case you're literally removing a commit, rebase isn't the right solution
22:29:33  <Eddi|zuHause> in a rebase you can drop a commit
22:30:01  <LordAro> you can, but eh
22:33:39  <peter1138> Evenig
22:33:50  <Samu> hi
22:34:05  <LordAro> o/
22:34:08  <peter1138> 22:20 < milek7> but reset will obviously throw away all changes
22:34:12  <peter1138> ^ it doesn't
22:36:25  <milek7> it won't allow me to use merge with dirty working tree after soft/mixed, and i wanted to get file with conflict markers again
22:39:07  *** andythenorth has quit IRC
22:39:23  <nielsm> will it crash or burn, or will sound actually be produced???
22:39:26  <nielsm> time to try it
22:39:55  <nielsm> nothing happens :D
22:40:02  <nielsm> at least nothing audible or visual
22:40:11  <peter1138> Samu, I didn't aim to improve pathfinder performance because that's a hard task. I aimed to prevent some situations that cause massive CPU usage from occuring. (But not all)
22:42:16  <nielsm> yeah I forgot to call Start on the driver :P
22:42:24  <peter1138> Heh
22:42:39  <LordAro> heh
22:45:08  <Samu> just decreate max number of nodes
22:45:45  <Samu> it's defaulted to 10000, maybe 5000? dunno
22:45:54  <LordAro> "just"
22:46:01  <Samu> :p
22:46:34  <Samu> or maybe, an idea
22:46:45  <Samu> have the pathfinder invoked on order insertion
22:47:09  <Samu> let it decide whether destination is too far
22:48:15  <Samu> hmm
22:49:39  <Samu> would kill opf
22:49:59  <LordAro> few would mourn its loss
22:50:51  <peter1138> So there is a remaining CPU hog issue.
22:51:23  <peter1138> Trying to find a path to a tile that is within the max distance but actually not reachable causes a hitch.
22:52:24  <LordAro> presumably because it's searching the whole map?
22:52:34  <peter1138> I wonder how many new bug reports #6784 will cause :D
22:52:42  <LordAro> ono
22:52:59  <peter1138> Not the whole map but enough. And it'll happen on every new tile.
22:53:15  <LordAro> oof
22:53:28  <peter1138> Well, that's why ship pathfinding already sucks.
22:53:31  <peter1138> It happens on every new tile.
22:53:41  <peter1138> Hence I have a patch to cache paths, but it's very much WIP.
22:53:45  <LordAro> that does seem inefficient
22:54:09  <LordAro> i was thinking that it should cache paths, then follow them until there's something in the way
22:54:23  <peter1138> Yup.
22:55:00  <peter1138> < "solves" a lot
22:55:02  <nielsm> if it's within range but no path could be found, set a counter that indicates "temporarily lost" and random walk until that counter reaches zero?
22:55:10  <nielsm> and/or send a news message
22:55:41  <LordAro> would still cause a hitch every n tiles
22:55:43  <peter1138> It spreads the load out, so you don't get 5000 pathfinding attempts in one tick.
22:56:00  <LordAro> some sort of limit on the pathfinder would work
22:56:14  <peter1138> There's a distance limit already, iirc.
22:56:26  <peter1138> Or at least, there is now :)
22:56:29  <Samu> have you tried my ship pathfinding depot stuff yet?
22:56:36  <Eddi|zuHause> the main problem with the ship pathfinder is the large number of near-identical paths
22:57:03  <peter1138> Hmm, yes, if it's with-in range, I'm not sure how far the pathfinder will actually go.
22:57:06  <Eddi|zuHause> the second problem is that it is repeated on every tile, as every tile is a junction
22:57:33  <LordAro> peter1138: yeah, referring to your "within range but unreachable" case
22:57:41  <peter1138> Yeah, sorry, sidetracked.
22:58:01  <peter1138> Hmm, we could do with a way to cancel a "Manage list" -> "Send to Depot" command.
22:58:01  <Eddi|zuHause> and "no path exists" is always the worst case for a pathfinder
22:59:58  <peter1138> I think my changes my scupper Samu's testing :p
23:00:02  <peter1138> *may
23:00:05  <Samu> i like the idea of caching path
23:00:21  <peter1138> That's what I asked you to attempt to do last year.
23:00:26  <Samu> keep working on it, it was also something I had in mind, but with limited code skills I didn't bother
23:00:37  <peter1138> heh
23:00:57  <peter1138> I think it did actually sort of work, but kept crashing.
23:03:02  <LordAro> i think pathfinder limit of x5 order length limit would work? (i.e. if the points are at max distance: )
23:03:15  * LordAro is better at paint than andy
23:04:24  <peter1138> Just make ships behave like triremes in civilization. If they get lost, they actually get lost, and disappear...
23:04:32  <LordAro> :D
23:05:00  <peter1138> o_O ... this patch adds a std::stack<Trackdir> path to struct Ship.
23:05:10  <peter1138> Well I can try it :)
23:05:16  <LordAro> ha
23:05:41  <LordAro> well, depends on its usage :p
23:09:00  <nielsm> okay well, now it does _something_:
23:09:06  <Samu> er, i made a review, maybe i wanted to post single comment, my bad
23:09:10  <nielsm> as the name says, it's very original
23:09:29  <LordAro> Samu: is fine either way
23:09:37  <peter1138> Nice tremolo attect.
23:09:39  <peter1138> affect...
23:09:42  <LordAro> Samu: you do have to submit the review though
23:09:50  <peter1138> I only had one pint, I don't think it's alcohol making me typo.
23:10:16  <Eddi|zuHause> well, "ad libitum" means "do what you want" :p

23:14:36  <peter1138> I must remember to not actually drink caffeine after, say, 2 or 3pm.
23:14:52  <peter1138> Weirdly, stone cold tea isn't too bad to drink *when you're expecting it*
23:15:15  <LordAro> that's probably how i'd describe it :p
23:15:26  <LordAro> i have a tendency to forget my tea
23:15:47  <Eddi|zuHause> call it "ice tea"?

23:17:01  <LordAro> Samu: use your words
23:17:06  <LordAro> that issue doesn't say anything at all
23:17:08  * peter1138 ponders replying to #7062, or playing Minecraft.
23:17:13  <LordAro> and relies on context that's only here
23:17:33  <peter1138> Wow, yeah, that's terrible.
23:17:53  <LordAro> Samu: the detail you use when responding to comments on your PRs is excellent, use that
23:17:58  <Samu> i dont know how to link stuff with each other
23:18:09  <peter1138> No need to link. Just write text.
23:18:15  <peter1138> Add some detail
23:18:28  <peter1138> Where were you trying to do. What happened. What did you expect?
23:18:35  <LordAro> but also this
23:19:00  <peter1138> Oh it's raining in Minecraft :/
23:19:20  <peter1138> And your title is bogus.
23:19:35  <peter1138> It should say what is happening now, not what wasn't happening in some older version.
23:20:17  <Eddi|zuHause> for some reason when it's raining in minecraft i have the urge to go fishing
23:20:23  <peter1138> Erm...
23:20:34  <peter1138> You realise I literally just picked up my fishing rod...
23:21:07  <Eddi|zuHause> i pulled a crazy good bow out with the fishing rod
23:21:16  <Samu> i'm blocked, can't think properly
23:21:47  <Eddi|zuHause> and after updating beyond 1.8 i could even repair it
23:22:21  <peter1138> I'm always on latest release.
23:22:39  <Samu> is this a better edit?
23:23:00  <LordAro> still needs more detail
23:23:02  <Eddi|zuHause> well, that was the latest release back then
23:23:10  <Eddi|zuHause> i don't play often
23:25:01  <Samu> i think im gonna copy paste irc text
23:25:15  <Samu> can't think properly
23:25:17  <LordAro> Samu: pictures are more helpful than savegames as well
23:27:18  <Samu> ok
23:27:35  <LordAro> well, sometimes
23:27:44  <LordAro> not to say that the savegame isn't useful
23:28:06  <peter1138> Damn it, I keep picking up... fish.
23:28:21  <peter1138> Oh and two water bottles. Nothing interesting :(
23:32:18  <Samu> some of the AIs in this situation would mass even more ships
23:32:30  <Samu> Trans or otvi
23:32:40  <Samu> they would all be lost
23:35:19  <Samu> because there's more cargo waiting at stations
23:35:57  <Samu> when the ship comes back, it reinvokes the pathfinder
23:36:02  <Samu> and gets lost again
23:37:33  <Samu> thx for the edit LardAro
23:37:37  <Samu> LordAro
23:39:52  <Samu> the only solution is path cache
23:39:59  <Samu> (i think)
23:40:46  <Samu> a means to avoid pathfinder being called every tile
23:42:43  <LordAro> as well as removing the manhattan check, i can see that working
23:42:50  <LordAro> caching the paths would improve things generally
23:44:50  <peter1138> The issue is actually that the orders should be invalid.
23:44:57  <peter1138> Buoys are necessary.
23:45:41  <peter1138> 22:46 < Samu> have the pathfinder invoked on order insertion
23:45:54  <peter1138> Would help...
23:46:10  <peter1138> But not if the map is changed later.
23:46:37  <peter1138> The ship is lost because its destination is too far. You need buoys.
23:46:47  *** nielsm has quit IRC
23:47:31  <LordAro> peter1138: but if the order was valid beforehand...
23:47:42  <LordAro> it would be a shame to break saves like that
23:47:54  <peter1138> It's not valid, it just worked because we didn't check properly.
23:48:27  <peter1138> Of course you can remove that check, but then you get performance hits again.
23:48:42  * LordAro is reminded of a Linus "never break userland" rant
23:49:25  <Samu> it does comes back into range only to have the pathfinder make him lost again
23:49:53  <Samu> so, buoys :(
23:51:13  <peter1138> Were always necessary in this situation
23:51:29  <Samu> nop, it's not lost in 1.8.0
23:51:47  <peter1138> Not what I meant.
23:51:54  <LordAro> peter1138: well, they were only necessary because of the bad pathfinder
23:52:36  <Samu> i think the savegame is 1.8.0 compatible
23:53:22  <peter1138> LordAro, of course, in this particular map the pathfinder wouldn't have too much trouble.
23:53:34  <peter1138> Open spaces of water is the issue.
23:54:09  <LordAro> how hard would it be to make the pathfinder prefer the shoreline?
23:54:33  <Samu> costs
23:54:43  <Eddi|zuHause> how would that help anyone?
23:54:54  <Samu> with costs, it's doable, somehow
23:55:15  <LordAro> Eddi|zuHause: less open spaces of water
23:55:24  <Samu> but then it would have to detect coast tiles
23:55:34  <Eddi|zuHause> that doesn't reduce the search space
23:55:37  <Samu> do more checks every tile
23:55:56  <Eddi|zuHause> just make it find worse paths
23:58:21  <Eddi|zuHause> to reduce the search space across open water, you could try to merge tiles into 2^n square superblocks that contain no obstacles
23:59:02  <Eddi|zuHause> store the size of the superblock in the tile
23:59:19  <Eddi|zuHause> upon changing water (clearing, flooding), invalidate the nearby superblocks, and recalculate
23:59:49  <LordAro> mm
