09:50:44  <Noldo> :)
09:51:27  <SmatZ> hello, about the http://git.openttd.org/cgi-bin/gitweb.cgi?p=svn/trunk.git;a=commitdiff;h=f3ef132edd72b0f74cb2e58c721890fa3c57fdbf;hp=80e74b2dbc7e500b936ed147f9f1e9e14738974f
09:51:46  <Noldo> I just feel like getting excited by some new hip feature or something
09:52:58  <Gekko> me too
09:53:05  <Gekko> like porno trains
09:53:10  <Noldo> plaah
09:53:10  <Gekko> with the newindustries newgrf
09:53:20  <Gekko> hooker cabs
09:54:25  <blathijs> SmatZ: what about it?
09:54:27  <SmatZ> wouldn't changing it to '(const) OldMemoryPoolNewBlock const *new_block_proc' do the job? eg. const pointer to (const) proc
09:55:40  <Rubidium> SmatZ: it isn't really important, but does that mean you can't change the pointer once it's written to?
09:56:19  <SmatZ> Rubidium: I suppose so - constant pointer is different than pointer to const
09:56:43  <SmatZ> Yes it is not important :)
09:56:57  <SmatZ> bye, I have a lunch

11:40:45  <Brianetta> Anybody know an easy way to calculate a base 2 logarithm?  Basically, an inverse of two-to-the-power?
11:40:50  <Brianetta> By easy, I mean possible to do on a handheld calculator (:
11:46:49  <ln-> does it have logarithms?
11:48:17  <Rubidium> Brianetta: integral or float result?
11:48:20  <ln-> if yes, wouldn't that be something like log[2] x = log[10] x / log[10] 2
11:49:04  <Brianetta> ln-: Thanks - you were just beaten by a guy on #linux

12:05:58  <valhallasw> Brianetta: log is irrelevant. ln isn't ;)
12:06:52  <valhallasw> and what's worse
12:07:00  <valhallasw> for mathematicians, log==ln
12:07:19  <valhallasw> i.e. ^e log
12:08:41  <Eddi|zuHause3> actually, "log" is whatever you view the most relevant
12:08:55  <Eddi|zuHause3> what you mean is "lg"
12:10:31  <CIA-1> OpenTTD: rubidium * r10763 /trunk/src/direction.h: -Documentation [FS#1098]: document direction.h. Patch by Progman.
12:11:12  <Brianetta> I always use the ln button anyway
12:11:18  <Brianetta> it takes less space ont he claculator's screen
12:11:31  <Brianetta> ln (4) is shorter than log (4)
12:11:39  <Brianetta> which lets me see more terms on the 12 cell display
12:12:16  <Nickman> would like to use a square root in my Squirrel AI, do I have to write an algorithm in Squirrel or can just add the function somwhere so it gets registerd tot he squirrel engine?
12:12:39  <Brianetta> What's squirrel?  I only know the webmail product
12:13:07  <Eddi|zuHause3> squirrel is the language of choice for the NoAI branch
12:13:14  <Nickman> http://squirrel-lang.org/default.aspx
12:13:47  <Brianetta> ah
12:14:35  <Eddi|zuHause3> Nickman: why use a sqrt?
12:14:36  <Brianetta> An iterative sqrt function is slow; wouldn't the presence of a lookup-based library function be better off?
12:14:52  <Eddi|zuHause3> integer-sqrt is probably not the greatest idea
12:15:15  <Eddi|zuHause3> instead of testing x==sqrt(a) i would check x^2==a
12:15:21  <Nickman> I would like to use a sqrt to make some estimate of the town area
12:15:51  <Brianetta> How is that necessary?
12:16:08  <Brianetta> Just wondering how you're performing the estimate
12:16:21  <CIA-1> OpenTTD: rubidium * r10764 /trunk/src/road.h: -Documentation: [FS#1099]: of road.h. Based on a patch by Progman.
12:17:16  <Nickman> I use the town population and then some operations to try and make an estimate of the size :)
12:17:21  <valhallasw> Eddi|zuHause3: lg is ^2 log, generally
12:17:38  <valhallasw> but that may be country or even university-dependent ;)
12:17:39  <Eddi|zuHause3> valhallasw: no, that is "ld"
12:18:34  <valhallasw> "lg, an abbreviation of logarithm of the base 2 in informatics (an alternative to ld)", but also "lg, an abbreviation of logarithm of the base 10 in Russia and other European countries", according to en.wikipedia
12:19:04  <Eddi|zuHause3> yes, germany is probably "other european country" :p
12:19:12  <SmatZ> :)
12:19:23  <valhallasw> yeah, well, the netherlands seems not to be european then :D
12:19:44  <valhallasw> or at least Leiden :)
12:22:59  <Nickman> cygwin can't execute the "squirrel_export.sh" script for NoAI Branch...
12:23:22  <Eddi|zuHause3> de.wikipedia says "ld" or "lb" for log_2
12:23:29  <Rubidium> Nickman: sh squirrel_export.sh
12:23:38  <Nickman> I'll try
12:23:49  <Eddi|zuHause3> and "lg" for log_10

20:06:20  <Phazorx> perrhaps relevant to evergoing autoreplace desyncs
20:06:28  <Phazorx> since before we used it - was not happening
20:06:39  <Phazorx> unfortunatelly after restart goes away
20:06:49  <Phazorx> so i could not reproduce it locally
20:06:58  <Rubidium> if you disable autoreplaces, does it work?
20:07:37  <Rubidium> i.e. does it not desync

21:02:32  <Phazorx> Eddi|zuHause: it is a cumulative runtime issue
21:02:50  <Phazorx> a save made day prior to desync does not desync when loaded
21:02:56  <Eddi|zuHause> exactly
21:02:58  <Phazorx> but will after some time

21:03:21  <Eddi|zuHause> and somehere inbetween there is a "shortest" time between load and desync
21:03:30  <Phazorx> Eddi|zuHause: i mean that all of these saves will desync eventualy
21:03:50  <Phazorx> i dont think it is proportinal to time
21:04:08  <Phazorx> at least it diesnt look like it now
21:04:44  <Rubidium> the problem is that the save made a day before the desync is actually after the desync occured
21:04:49  <Eddi|zuHause> the timeline is like: <load> |----- <event> ---- <desync>
21:04:51  <Rubidium> it is just before the desync was notified
21:05:12  <Phazorx> Rubidium agreed: any suggestions?
21:05:19  <Eddi|zuHause> so you need to find a savegame where time between "load" and "event" is shortest
21:05:22  <Rubidium> rather: <load> |----- <desyninc event> ---- <notification of the desync>
21:05:43  <Phazorx> Eddi|zuHause: that's a lot of load/save
21:05:43  <Eddi|zuHause> yeah, your version is more verbose :)
21:05:48  <Rubidium> Phazorx: can you compile yourself?
21:05:50  <Phazorx> and no guaranteed result
21:05:55  <Phazorx> Rubidium: i always do
21:06:04  <Rubidium> open network.h
21:06:11  <Rubidium> uncomment line 21
21:06:15  <Rubidium> and recompile
21:06:55  <Phazorx> /#define ENABLE_NETWORK_SYNC_EVERY_FRAME ?
21:07:08  <Rubidium> oh, never mind
21:07:22  <Rubidium> you said that the desync happened if you run the server for a while
21:07:30  <Phazorx> correct
21:07:33  <Rubidium> and then join, without performing any action
21:08:21  <Phazorx> yes
21:08:21  <Phazorx> it's a data/cache based desync looks like it
21:08:21  <Rubidium> so the only thing that can be done is redoing it again and find the earliest join date that desyncs happen
21:08:21  <Phazorx> something that needs to be is not saved or some data is "assuemed" valid on cline t when it is not
21:08:21  <Eddi|zuHause> yeah, that's a typical cache/recalculation symptom
21:09:47  <Phazorx> hmm... there must be more analytical aproach

21:10:03  <Rubidium> and then try to move the begin date forward; i.e. load savegame, proceed a day, reload savegame wait till "earliest desync join date", join, check whether it desyncs
21:10:05  <Phazorx> cuz save/load is mroe like guessing and elimination which always takes a whie;
21:10:56  <Eddi|zuHause> well you can do one long run with daily save, and then do a binary search over those savegames
21:10:58  <Rubidium> Phazorx: it is guessing, but making the desync testing faster makes solving it much faster
21:11:20  <Rubidium> as I have to run the same thing a gazillion times to backtrace the cause of the desync

21:12:14  <Phazorx> is there a way to get a date from server concsole?
21:12:19  <Rubidium> and that takes at least 20 iterations and usually much more, so any time gained there is good
21:12:21  <peter1138> "getdate"
21:12:22  <Rubidium> Phazorx: getdate
21:12:29  <Phazorx> thanks
21:18:23  <Eddi|zuHause> daily autosave is pretty easy, just move the line _do_autosave = true; within the IncreaseDate function in date.cpp
21:18:49  <Eddi|zuHause> before the check if a new month begins
21:19:29  <Eddi|zuHause> the number of autosaves to keep might be a problem then, because they are overwritten pretty fast
21:20:09  <Rubidium> there's an patch option to get autosaves with dates

22:19:04  <Sacro> Windows Mobile 5.0 SDK for Pocket PC?
22:19:17  <Eddi|zuHause> yes... "just"... but the infrastructure for that is not there
22:19:22  <Sacro> 700KB//s
22:19:26  <Sacro> no so bad
22:19:26  <TrueBrain> Sacro: yes
22:23:39  <Sacro> need activesync too i guess
22:23:59  <TrueBrain> not if you use emulators
22:24:27  <Sacro> i have the actual phone :p
22:24:39  <TrueBrain> you don't want to send it to there every time
22:24:46  <TrueBrain> it crashes the phone in the worst case
22:24:48  <TrueBrain> and it takes for ever
22:24:55  <TrueBrain> in the emulator you can save a state
22:25:00  <TrueBrain> and make it easier to work with it
22:25:06  <TrueBrain> (although it still is a big PAIN IN THE ASS)

22:26:36  <Xintron> How do I get planes?
22:26:53  <Rubidium> build an airport and click on the hangar
22:27:01  <Xintron> ok
22:27:11  <Rubidium> looks a little like a train/road depot, but with a curved roof and it's grayish
22:27:22  <Xintron> I found it
22:27:24  <Xintron> thanks :)
22:27:26  <Xintron> Love this game
22:37:20  <Sacro> TrueBrain: you got the ppc5 binary?
22:38:09  <Xintron> If a train crashes, what do I do with that train?
22:38:21  <Sacro> Xintron: clear it up

23:05:03  <SmatZ> sorry
23:05:26  <Rubidium> well, those windows are (really) not needed for game play
23:05:51  <Rubidium> the difficulty is small enough when in the main menu, but in the normal game you've got the toolbars

23:06:04  <TrueBrain> Wolf01: if some idiot wants to do so...
23:06:22  <Rubidium> and the patch window is just generally too large

23:16:45  <SmatZ> are you testing gcc 4.2.x to compile openttd?
23:17:34  <TrueBrain> are you?
23:17:49  <SmatZ> yes
23:18:10  <SmatZ> I just get irritating warnings /mnt/svn/openttdcoop/src/yapf/../misc/blob.hpp:376: warning: assuming signed overflow does not occur when assuming that (X - c) >= X is always true
23:18:20  <SmatZ> so if any of devs is aware of that
23:18:41  <SmatZ> it can be avoided by adding -fno-signed-overflow or something like that...
23:19:19  <CIA-1> OpenTTD: rubidium * r10776 /trunk/src/tunnelbridge_cmd.cpp: -Fix [FS#1081]: you would not pay for some foundations of bridges whereas you would pay for others.
23:19:20  <Rubidium> SmatZ: that's a compiler bug
23:19:41  <CIA-1> OpenTTD: truelight * r10777 /trunk/src/station.h: -Fix: don't put the ctor debug on lvl3, it is more a lvl5 debug
23:20:30  <Rubidium> the compiler does optimizations and determines that some value is always positive, whereas it does not need to be always that way
23:24:50  <Wolf01> http://www.esoftinteractive.com/forums/viewtopic.php?t=1658&sid=d3a42203f52e71c995e8bc0a2b4fdafc looooooooool
23:25:06  <Rubidium> SmatZ: do you think the following is wrong?
23:25:07  <Rubidium> 		assert(idx >= 0); assert(idx < Size());
23:25:18  <SmatZ> Rubidium: I am looking into the code...
23:25:20  <Rubidium> where idx is a signed integer
23:25:37  <Rubidium> and Size() too
23:26:24  <CIA-1> OpenTTD: truelight * r10778 /trunk/src/ (6 files in 2 dirs):
23:26:24  <CIA-1> OpenTTD: -Fix: one-liners to allow MSVC and WINCE to work together (or anyway, a step towards that goal)
23:26:24  <CIA-1> OpenTTD: -Fix: put DEBUG lines under WINCE via a function designed for just that under WINCE
23:27:51  <SmatZ> Rubidium: seems everything works ok - the only case when it would fail would be if one/both of idx and Size() were big positive/negative numbers
23:28:18  <SmatZ> and they are not... and compiler is just giving information it is assuming the signed overflow doesn't occur

23:29:48  <SmatZ> Rubidium: I just needed more time to imagine what is going on :(
23:30:28  <Rubidium> but the warning has nothing to do with the actual checks
23:31:18  <Rubidium> otherwise it has to give this warning *everywhere* where you check stuff like "val >= 0 && val < 10"
23:31:23  <SmatZ> maybe ... maybe the code generated does, I will check the asm
23:33:03  <Rubidium> Wolf01: stupid Sergej
23:37:02  <SmatZ> Rubidium: maybe it checks Size() - idx >= 0 instead
23:37:36  <SmatZ> assuming it won't overflow, it has the same effect... except different assert triggered
23:39:18  <Rubidium> still, I don't care how it optimizes as long as it does it correctly and does not give warnings about it's own optimized code
23:42:46  <SmatZ> what kind of warnings do you mean? gcc 4.2.x gives those warnings ... they are not critical at all, but they are still warnings
23:43:06  <SmatZ> mmm nevermind, you have something really more interesting to do :) sorry
23:43:07  <Rubidium> the warnings gcc gives
23:43:43  <Rubidium> SmatZ: we shouldn't hide GCC warnings that GCC finds in it's own optimized code
23:44:49  <SmatZ> Rubidium: thanks, that explains everything
23:45:42  <TrueBrain> night all
23:45:58  <Rubidium> on the other hand, I wonder whether they do know about this issue
23:46:18  <SmatZ> TrueBrain: night
23:47:26  <SmatZ> Rubidium: do you think this is an issue? it seems to give information like 'I am doing some expectations while optimising, if the C code was not conforming to the standards, it might not work aas expected'
23:48:22  <Rubidium> http://gcc.gnu.org/ml/gcc-patches/2007-04/msg01885.html <- it even is a regression

23:51:31  <ln-> indeed...
23:52:11  <SmatZ> Rubidium: this seems to be an error because of excessive warning, but not all warnings are excessive
23:52:48  <SmatZ> it is from the gcc testsuite, where it shouldn't give any warning
23:52:49  <SmatZ> or os
23:52:50  <SmatZ> so
23:53:37  <glx> in the followup of the message Rubidium pointed they even seem to have a fix

23:55:59  <Eddi|zuHause> SmatZ: i know what an overflow is, that is not the point
23:56:52  <SmatZ> Eddi|zuHause: true, it was not the correct text to paste ...

23:57:21  *** skidd13 [~skidd13@p548A6526.dip.t-dialin.net] has joined #openttd
23:57:50  <Eddi|zuHause> SmatZ: the point is that the code at the given lines does not do any arithmetics at all, so if the compiler "optimises" any arithmetics in there, it has to prove that it does not change the semantics of the code (beyond what the specs allow)
23:58:12  <Rubidium> adding -fstrict-overflow does not sounds like the way to go; there is a lot of code that assumes that overflows happens and (by some "law") there will be one that uses signed integers.
23:58:40  <SmatZ> Eddi|zuHause: "-fstrict-overflow tells the compiler that it may assume that the program follows the strict signed overflow semantics permitted for the language: for C and C++ this means that the compiler may assume that signed overflow does not occur."
23:58:52  <Eddi|zuHause> so that warning does not warn about the code, but about internal code replacements that the "user" should not have to know about
23:59:16  <SmatZ> they are talking about 'strict signed overflow semantics permitted for the language' - what is the standard?
23:59:45  <SmatZ> Rubidium: the problem is that -fstrict-overflow is enabled by default with -O2 and higher ... maybe even -O1
23:59:54  <SmatZ> Eddi|zuHause: yes
