| 04:18 | <TheJosh> | where can i put some code to clean up some stuff when a game is abandoned? |
| 04:18 | <TheJosh> | aka dynamic array |
| 04:19 | <@peter1138> | we just rely on the OS ;p |
| 04:19 | <@peter1138> | i don't think ottd runs on any systems that don't free up used memory on exit |
| 04:20 | <boekabart> | it runs... once |
| 04:20 | <Kjetil> | Oh noes.. it won't run on DOS ! aaaaahhh |
| 04:20 | <boekabart> | maybe twice |
| 04:20 | <CIA-1> | OpenTTD: rubidium * r10054 /trunk/src/ (4 files in 2 dirs): -Codechange: make the industries cost modifier look more like the original one, so it's much easier to support industries that use this original format. |
| 04:20 | <@peter1138> | Kjetil: does DOS even have a concept of free memory? heh |
| 04:20 | <@peter1138> | i imagine any dos 'extender' would handle it anyway |
| 04:20 | <@peter1138> | just guessing though |
| 04:20 | <boekabart> | well there was always too little, so it must have |
| 04:21 | <Rubidium> | anything about 640kB is free, right? |
| 04:21 | <Rubidium> | *above |
| 04:21 | <@peter1138> | i think 'mem' knew of stuff in EMS/XMS, so... |
| 04:22 | <@peter1138> | hmm, mem is qemu says so, but that's freedos |
| 04:22 | <boekabart> | peter1138: pretty sure that the heap of the protected mode 'layer' would clean up better than openttd does :) |
| 04:22 | <@peter1138> | Extended (XMS) 130,048K 12,744K 117,304K |
| 04:22 | <boekabart> | you run DOS on the side? :) |
| 04:22 | <@peter1138> | yeha |
| 04:22 | <TheJosh> | so noone cleans up there heap objects anymore? |
| 04:22 | <Kjetil> | peter1138: haha.. I was using Dos the other day. I am amazed how poorly designed it is. Why did people buy that crap ?.. |
| 04:22 | <@peter1138> | ottd only cleans up between games ;) |
| 04:22 | <TheJosh> | isnt a 'memory leak' a non-cleaned up heap object? |
| 04:23 | <Rubidium> | no |
| 04:23 | <TheJosh> | i have a unopened genuiene copy of MS-DOS 6.2 |
| 04:23 | <Nickman> | Cool :D |
| 04:23 | <Rubidium> | a memory leak is a non-cleaned up heap object that doesn't have any reference to it anymore |
| 04:23 | <Biff> | memory leak is when you have allocated memory which has 0 references to it |
| 04:23 | <@peter1138> | "FreeDOS is resident in the high memory area." |
| 04:23 | <@peter1138> | woo, intelligent |
| 04:23 | <TheJosh> | but if the program closes, there will be no reference to my object |
| 04:24 | <@peter1138> | still only 619KB of 'conventional' memory free |
| 04:24 | <@peter1138> | heheh |
| 04:24 | <Biff> | if the program closes the memory is free |
| 04:24 | <@peter1138> | been AGES since i heard that conventional memory term |
| 04:24 | <Kjetil> | Biff: if you run a proper os :P |
| 04:24 | <@peter1138> | even windows frees it, heh |
| 04:24 | <Biff> | what os doesnt free memory? |
| 04:24 | <Kjetil> | dos :P |
| 04:24 | <TheJosh> | old windows |
| 04:25 | <Biff> | i think win9x had some bugs, but it did it |
| 04:25 | <TheJosh> | 95 and 98 |
| 04:25 | <Biff> | well, it did free memory, but there were some bugs that were never fixed, so it didnt always manage to free memory |
| 04:25 | <boekabart> | 95/98 tried to, but didn't have the possibility to enforce it 100% i think |
| 04:25 | <TheJosh> | and XP until your program uses about 800mb of ram (i tested it once by mkaing lots of integers) |
| 04:25 | <Biff> | hehe |
| 04:26 | <TheJosh> | then at 90% full or so it just drops off |
| 04:26 | <Biff> | that seems like a hard way to do it .-) |
| 04:26 | <TheJosh> | i guess the GC went through |
| 04:26 | <Biff> | what GC? |
| 04:26 | <boekabart> | that's swapping. look at VM size rather than memory size |
| 04:26 | <TheJosh> | nonetheless, can i execute code to clean up this memory? |
| 04:26 | <TheJosh> | GC = garbage collector |
| 04:26 | <@peter1138> | what GC, not what is GC |
| 04:26 | <Biff> | yes, did you use a gc language? |
| 04:27 | <TheJosh> | no this experiment was in c++ |
| 04:27 | <Biff> | if you used something like java, its the java vm that frees up the memory, by doing reference counting |
| 04:27 | <boekabart> | XeryusTC: we talked about GC yesterday too |
| 04:27 | <Nickman> | C and C++ doesn't do automatic GC .. |
| 04:27 | <Nickman> | as I recall... |
| 04:27 | <XeryusTC> | :o |
| 04:27 | <boekabart> | you can easily replace your malloc/free by a GC library. |
| 04:27 | <TheJosh> | the os must then if what you guys are taling about is true |
| 04:27 | <Biff> | ok, then there usually is no GC |
| 04:28 | <Biff> | TheJosh: the os knows when the process is closed, and it can mark its memory as free |
| 04:28 | <Nickman> | in C++ you have to do all garbage collection yourself. But this only goas for dangling pointers... |
| 04:28 | <boekabart> | if you close a program when debugging it in in msvc, i'll give you a list of all the memory blocks unfreed |
| 04:28 | <Nickman> | local varables and stuff are removed when they go out of scope |
| 04:28 | <Nickman> | and indeed, when the program terminates, the OS recieves all the memory again ;) |
| 04:28 | <Biff> | boekabart: ah, something like valgrind |
| 04:28 | <boekabart> | then you can set a breakpoint on their allocation (if repeatable) |
| 04:29 | <@peter1138> | valgrind is just designed to make it impossible to test by being really slow... |
| 04:29 | <boekabart> | so if you make sure the game does 100% the same thing on a run (until closing) you can figure out what blocks they are. |
| 04:29 | [~] | peter1138 remembers that days when newgrf leaked memory like a sieve |
| 04:29 | <TheJosh> | where can i put some code after the game has been closed? |
| 04:30 | <@peter1138> | UnInitializeGame() in openttd.cpp does some clean up |
| 04:30 | <boekabart> | class bla { public: ~bla() { /* the code */ } } onebla; |
| 04:30 | <Nickman> | when the game is closed you shouldn't do anything, it gets thrown away anyway... :D |
| 04:30 | <@peter1138> | not all pools are cleaned up though. hmm. |
| 04:31 | <Nickman> | yeah, use destructors... |
| 04:31 | <@peter1138> | boekabart: roflcopters |
| 04:31 | <Biff> | is there any free space in savegames? |
| 04:31 | <boekabart> | only in small ones :) |
| 04:31 | <TheJosh> | peter1138: thanks for an actual answer |
| 04:31 | <Biff> | or rather, if i wanted the savegame to remember last railtype used, would it break compatibility? |
| 04:32 | <boekabart> | Biff: you can add a variable to patches |
| 04:32 | <boekabart> | without UI |
| 04:32 | <boekabart> | you'll have to bump the savegame version though |
| 04:32 | <Rubidium> | Biff: not necessarily, but requires quite a lot of work to do it in a way that you can still load old savegames |
| 04:33 | <Biff> | i see |
| 04:33 | <Rubidium> | so, technically possible, practically unfeasible |
| 04:34 | <Biff> | i hate building the wrong type of rail |
| 04:34 | <Biff> | :p |
| 04:34 | <TheJosh> | does openttd mainly use malloc or new ?? |
| 04:34 | <TheJosh> | to create an object on the heap |
| 04:34 | <@peter1138> | mainly malloc |
| 04:34 | <TheJosh> | malloc and free? |
| 04:35 | <Rubidium> | no, malloc and delete and new and free ofcourse ;) |
| 04:35 | <TheJosh> | ok thanks |
| 04:35 | <Rubidium> | *kuch* |

| 04:40 | <boekabart> | TheJosh: 19?!? |
| 04:41 | <boekabart> | TheJosh: is that including english? just kidding :) |
| 04:41 | <TheJosh> | some are dialects. 15 to be safe |
| 04:41 | <TheJosh> | also depends what you think of html and css |
| 04:41 | [~] | boekabart would like to see a list :) |
| 04:41 | <Rubidium> | does that include C? |
| 04:41 | <@peter1138> | html and css are not programming languages |
| 04:41 | <TheJosh> | probably shouldnt |
| 04:42 | <TheJosh> | i know, but they still require learning |
| 04:42 | <@peter1138> | (but javascript is, of course) |
| 04:42 | <ln-> | TheJosh: html and css are of course not programming languages. |
| 04:42 | <boekabart> | TheJosh: xsl is, though. |

| 04:42 | <Rubidium> | xml and uml neither, unless you're talking about exectable uml |
| 04:43 | <TheJosh> | i know all that |
| 04:43 | <TheJosh> | of course there not programming langues. they are markup languages (except css, thats a style language0 |

| 04:45 | <ln-> | i don't think regular expressions are a programming language either. |
| 04:45 | <Noldo> | gotta love them |
| 04:46 | <Rubidium> | does "This user can program in X" mean "This user did some stuff in language X, but doesn't have a deep understanding of the langauge"? |
| 04:46 | <Noldo> | ln-: it's a language defining language |
| 04:46 | <Rubidium> | in that case my list becomes pretty long too |
| 04:46 | <TheJosh> | yeah |
| 04:46 | <TheJosh> | but a stack on that list I do have a deep understanding of |
| 04:46 | <blathijs> | Saying "XML is a programming language" is like saying "Text is a programming language", really |
| 04:47 | <TheJosh> | proably c/c++, scheme and asm i dont know very well |
| 04:47 | <TheJosh> | im not saying xml is a programming language |
| 04:47 | <TheJosh> | ok 14 programming langues, 11 im good at |
| 04:47 | <blathijs> | The reverse also goes, btw :-) |
| 04:47 | <blathijs> | oh, we're counting programming languages :-) |

| 04:48 | <boekabart> | blathijs & Rubidium : http://www.digitalmars.com/d/ |
| 04:48 | <Rubidium> | yeah, I know that (a little) |
| 04:49 | <ln-> | when I change text to bold and italics in openoffice, and even change font, am I programming in openofficeish? |
| 04:49 | <blathijs> | ln-: If you like to think so, then yes ;-p |
| 04:49 | <Rubidium> | hmm, does vhdl count? |
| 04:49 | <boekabart> | DUH! |
| 04:49 | <boekabart> | of course it does |
| 04:50 | [~] | boekabart wonders if he just said duh out load |
| 04:50 | <Rubidium> | well, it is a hardware description language |
| 04:50 | <boekabart> | well.. isn't C is a software description language :) |
| 04:50 | <Rubidium> | ofcourse it looks awfully lot like a programming language |
| 04:51 | <boekabart> | it's all if (input) then output(); |
| 04:52 | <Rubidium> | in that case... I can (i.e. once programmed in) [..lot of languages..] ;) |
| 04:53 | <skidd13> | Remember all the shell/batch/makro languages... The list is huge. |
| 04:53 | <boekabart> | i'm quite a btm expert myself :) |
| 04:53 | <TheJosh> | i only wrote bash because i can do loops and ifs and stuff like that in bash |
| 04:58 | <TheJosh> | i think i am killing the code |
| 04:58 | <TheJosh> | dont worry i will get my patch working before i release it |
| 04:58 | <skidd13> | Did someone tried the new ms batch thing (don't remember the name)? |
| 04:59 | <boekabart> | i've played with it a while ago |
| 04:59 | <boekabart> | but man didn't work, so i gave up quickly |
| 04:59 | <boekabart> | can't imagine why they had to invent smth new |

| 07:52 | <TheJosh> | "texteff.cpp:282: error: cannot convert ‘TextEffect’ to ‘TextEffect*’ in assignment" (aka line 42) |
| 07:52 | <boekabart> | TheJosh: that was what Rubidium and I were expecting |
| 07:52 | <@peter1138> | boekabart: not if you do it at the right place |
| 07:53 | <boekabart> | peter1138: like i did in the 'renderer' class patch, do you consider that the right place or not? |
| 07:53 | <@peter1138> | no, that's way too low |

| 07:55 | <boekabart> | #define pure = 0 :) |
| 07:55 | <TheJosh> | boekabart: so how do I avoid casting hell? how can something seemingly so simple be so crap? |
| 07:55 | <boekabart> | without the :) |
| 07:55 | <boekabart> | TheJosh: 1 sec |
| 07:55 | <TheJosh> | ok thanks |
| 07:55 | <boekabart> | (by not taking this approach, by the way). |
| 07:56 | <@peter1138> | boekabart: with that you're still telling it what to draw, including loading and looking up sprites |
| 07:56 | <boekabart> | TheJosh: http://paste.openttd.org/87 |
| 07:57 | <boekabart> | peter1138: looking up, yes, loading, no (that's done in DrawSprite or GfxMainBlitter i think) |
| 07:57 | <Nickman> | blathijs: http://pastebin.ca/547585 any idea? |
| 07:59 | <boekabart> | peter1138: obviously, the EmptyRenderer returns immediately on all calls. (or returning a dummy value) |
| 08:00 | <@peter1138> | you can save a lot of processing by returning early in ViewportDraw |
| 08:00 | <TheJosh> | boekabart: still segfaults. that function does other stuff with te after the loop |
| 08:00 | <@peter1138> | you can save even more by not calling doing anything with windows at all |
| 08:01 | <TheJosh> | things like "te->string_id = msg;" |
| 08:01 | <TheJosh> | am I asking at a bad time? |
| 08:01 | <boekabart> | TheJosh: are you sure the _list... is not NULL there? |
| 08:02 | <TheJosh> | how do you output an error? |
| 08:02 | <TheJosh> | printf? |
| 08:04 | <valhallasw> | depends what you want to happen |
| 08:04 | <TheJosh> | i just need to know when my funciton is called |
| 08:08 | <TheJosh> | the list is defidently there |

| 08:17 | <boekabart> | right |
| 08:17 | <blathijs> | Nickman: I don't know what causes that, perhaps some library should be linked in that isn't... |
| 08:17 | <boekabart> | replace line 13 by |
| 08:17 | <boekabart> | te = &_text_effect_list[i]; |
| 08:17 | <blathijs> | Nickman: (btw, do document your findings on the wiki if you get it to work..) |
| 08:17 | <boekabart> | and init te with NULL and test for it after the for |
| 08:18 | <Eddi|zuHause2> | that code does not make any sense to me |
| 08:18 | <Nickman> | blathijs: I got the compiling to work by placing the zlib files into the pnglib folder :p |

| 08:19 | <TheJosh> | "texteff.cpp:284: error: request for member ‘string_id’ in ‘te’, which is of non-class type ‘TextEffect*’" |
| 08:19 | <Eddi|zuHause2> | e.g. why is it te.string_id once, and te->string_id the other time? |
| 08:19 | <TheJosh> | 284 is line 14 |
| 08:20 | <Nickman> | te is a pointer, replace te te. with te-> on line 14 and try again |
| 08:20 | <TheJosh> | changed te.string_id to te->string_id |
| 08:20 | <Nickman> | and? |
| 08:20 | <TheJosh> | it compiles, runs, doenst segfault |
| 08:21 | <TheJosh> | but also does nothing (the array is not updated) |
| 08:21 | <Nickman> | tada ;) |
| 08:21 | <Nickman> | hehe :D |
| 08:21 | <TheJosh> | the function does not work |
| 08:21 | <Nickman> | where does it have to add it? |
| 08:21 | <TheJosh> | to the array. |
| 08:21 | <Nickman> | what array needs to be updated? |
| 08:22 | <Nickman> | could you point me to the line where you update the array? |
| 08:22 | <TheJosh> | the loop is to find a free spot in the array. i did not code this, i am just tryng to get it working with a dynamic array so i can have 25 or 1000 elements |
| 08:22 | <TheJosh> | the original code did not have a update it used pointers i guess |
| 08:23 | <Nickman> | so, in the for loop, you are looking for an empty spot? |
| 08:23 | <TheJosh> | yes |

| 08:25 | <Nickman> | why don't you change this TextEffect *te; into TextEffect te; |
| 08:25 | <Nickman> | and don't work with silly pointer? |

| 08:25 | <TheJosh> | i dunno |
| 08:26 | <TheJosh> | its just the way the old code was |
