Dev meeting minutes 2010-06-13

Post by zerver »

<[RoX]Tobi> welcome all
<[RoX]Tobi> I assume zerver and daftalx (who's been invited for the OS X stuff) will join later
<[RoX]Tobi> lets start then

== Review meeting minutes past meeting ==
<[RoX]Tobi> any comments?
<[RoX]Tobi> ok, no comments
<[CoW]Kloot> hmm didn't we agree that point could be removed last meeting?
<[RoX]Tobi> that was the other point, about etherpad
<[RoX]Tobi> but I guess this doesn't add really much either
<[CoW]Kloot> ah right
<[RoX]Tobi> shall we remove it next time?
<[LCC]jK> +1
<zerver> perhaps better to make a new point on the agenda if someone wants to discuss something from last meeting
<[ARP]hoijui_g5> yeah, remove next time
<[RoX]Tobi> ok
<[ARP]hoijui_g5> yeah that

* We don't review last meetings minutes, point has been removed from the agenda

== Progress of stuff to be done before release ==
first subpoint: ===Do not flush output in sim thread (patch by SirMaverick)===
<[LCC]jK> zero here
<[RoX]Tobi> zero progress or zero work to be done?
<[LCC]jK> zero work to be done
<[RoX]Tobi> ok, great
<[ARP]hoijui_g5> Kloot had a look at that patch
<[ARP]hoijui_g5> if i remember right, it should not be used
<[ARP]hoijui_g5> just flush should be removed
<[ARP]hoijui_g5> ?
<[RoX]Tobi> I had a look too, I put some comments in the commit on github before I even noticed the mantis report
<zerver> output is buffered anyway, so if we just dont force flush...
<[ARP]hoijui_g5> mm
<[RoX]Tobi> yeah IMO the correct 'solution' is not flushing, as it's way easier as a thread to flush
<[LCC]jK> isn't it possible to flush in the crashhandler?
<[CoW]Kloot> I read through the patch but didn't consider the buffered aspect until I noticed the discussion
<[RoX]Tobi> and with both solutions it isn't guaranteed anyway everything appears on disk on a crash that bypasses crash handler in some way
<[RoX]Tobi> which is the entire point of the flush
<[RoX]Tobi> [LCC]jK: no need to flush there when it could just close the file cleanly
<[LCC]jK> k
<zerver> if process crashes, are not all steams auto flushed?
<[RoX]Tobi> (which it already does, I think)
<[RoX]Tobi> not that I know
<[ARP]hoijui_g5> yeah, Linux crash handler already does close logOutput
<[RoX]Tobi> probably OS level buffers are, but buffers in memory (i.e. in libc functions) aren't
<zerver> ah
<[ARP]hoijui_g5> would the best solution not be, to limit logging to a usefull level?
<[ARP]hoijui_g5> and keep it as it is?
<[RoX]Tobi> nah, I think just not flushing is ok atm
<[RoX]Tobi> crash handler seems to work most of the time, right?
<[ARP]hoijui_g5> ok :-)
<[LCC]jK> hmmm only endless loops may bypass the crashhandler
<[ARP]hoijui_g5> yes
<[RoX]Tobi> shouldn't the hang detection trigger then?
<[RoX]Tobi> or is that only compiled in in MT builds?
<zerver> only enabled in mt
<zerver> but compiled always
<zerver> should this be changed?
<[ARP]hoijui_g5> default enabled in MT? but cna be enabled through config in normal build?
<zerver> yes
<[ARP]hoijui_g5> what is the downside of having it on?
<zerver> one extra thread
<[LCC]jK> Spring already has >6-8 threads, one more or less doesn't matter imo
<[ARP]hoijui_g5> hye, daftalx is around
<[LCC]jK> esp. when it doesn't use much cpu time
<[ARP]hoijui_g5> but i can not send him a PM in chat
<[ARP]hoijui_g5> as he is on IRC only..
<[ARP]hoijui_g5> ah is ok...
<[RoX]Tobi> I'm fine with enabling it
<zerver> thread wakes up once a second and executes 5 instructions or so
<zerver> ok, can do it
<[LCC]jK> so move flush to hand detection thread and remove it from sim?
<[ARP]hoijui_g5> :D
<zerver> llol
<[RoX]Tobi> I'd even say just remove flush completely, or maybe completely after loading finished
<[RoX]Tobi> (i.e. only flush during loading)
<[ARP]hoijui_g5> mmm good idea!
<[RoX]Tobi> or only keep it in debug builds :)
<[ARP]hoijui_g5> ahh.. also good
<[ARP]hoijui_g5> both things
<[LCC]jK> so flush in myGL.h::PrintLoadMsg
<[ARP]hoijui_g5> hm?
<[RoX]Tobi> good
<[RoX]Tobi> who will do this?
<zerver> So if we remove the flush, isnt there risk of missing output after crash?
<zerver> or do we close logOutput in hang and crash handlers?
<[RoX]Tobi> I think that's done
<zerver> better check it
<[RoX]Tobi> yup
<[RoX]Tobi> should I move the flush?
<zerver> Plz
<[RoX]Tobi> ok I'll do that
<[ARP]hoijui_g5> yes..
<[ARP]hoijui_g5> in linux it surely is done
<[ARP]hoijui_g5> in crash handler
<[ARP]hoijui_g5> it has to close log output to be able to write the stack trace to the same file

* We don't apply the patch by SirMaverick
* Instead we remove flushing in Sim thread and verify streams are closed in crash handling (Tobi)
* Hang handing should be default enabled in single thread build (zerver)

== Do not build dedicated with "all"? ==
<[RoX]Tobi> I agree
<[ARP]hoijui_g5> ok :-)
<[ARP]hoijui_g5> i guess it is best if you do this too, so you can coordinate it with buildbot
<[ARP]hoijui_g5> (as you have to add ti again there, i guess)
<[RoX]Tobi> ok
<[RoX]Tobi> I might ask you how to change cmake things but that's for after meeting
<[ARP]hoijui_g5> ok
<[RoX]Tobi> anyone who doesn't agree?
<[LCC]jK> is there any reason for this?
<[RoX]Tobi> oops
<[CoW]Kloot> "all" does imply every buildtarget
<[RoX]Tobi> [LCC]jK: consistency with spring-gml / spring-hl
<[ARP]hoijui_g5> becuase practically nobody needs dedidcated, but everyone that compiles spring, builds it
<[LCC]jK> and how do ppl get currently dedicated binaries?
<[ARP]hoijui_g5> yeah and that
<[RoX]Tobi> although I tend to agree with kloot that all implies every buildtarget :)
<zerver> Could you please name it spring-mt instead of spring-gml ?
<zerver> GML is just my lib and may be discarded any time :)
<[ARP]hoijui_g5> i thoug hthe consensus was, that it is gml, not MT
<[CoW]Kloot> just change "all" to "almost-everything" and problem solved ^^
<[ARP]hoijui_g5> as MT woudl be if Sim was MT
<[ARP]hoijui_g5> yeah.. the problem is, that all is auto generated by cmake
<[ARP]hoijui_g5> we could only have a "really-all"
<zerver> Okay, not a big deal call it gml then
** daftalx joined the channel.
<[ARP]hoijui_g5> hello!
<[CoW]Kloot> or mt-gml?
<daftalx> hi (sorry for the time shift...)
<[RoX]Tobi> welcome daftalx
<[LCC]jK> welcome
<zerver> I'm not sure Sim will ever be MT though
<[ARP]hoijui_g5> yeah.. ;-)
<[CoW]Kloot> yeah probably not
<[LCC]jK> not in near future
<zerver> It's one of those things you can try to invent if you have too much brain cells for the moment
<[LCC]jK> maybe someday part of it could be optimized with OMP
<[ARP]hoijui_g5> in my eyes, ebst woudl be, if we call it gml, and somethign like "MT (GML)" wherever the user will see it
<[ARP]hoijui_g5> eg in the lobby, or in the instalelr
<zerver> I promised thefatcontroller that the version string would contain "MT" earlier
<[ARP]hoijui_g5> hehe
<[ARP]hoijui_g5> ..why?
<[ARP]hoijui_g5> or why does he care?
<zerver> he wants to detect it and auto disable widgets
<[RoX]Tobi> zerver: isn't that already put in it in GameVersion.cpp ?
<[ARP]hoijui_g5> ah
<[RoX]Tobi> (independent of how the makefile target is called)
<zerver> yeah, version is independent i think
<[RoX]Tobi> daftalx: this is agenda btw:
<[ARP]hoijui_g5> hmm.. so it is just overall a bit inconsistent now :D
<[ARP]hoijui_g5> should we change that?
<[ARP]hoijui_g5> to all MT or all GML
<zerver> Use spring-mt.exe if it isn't too much work to change
<[ARP]hoijui_g5> ok
<zerver> I don't think we will have different MT variants in the future, even if we find a way to make Sim threaded.
<[RoX]Tobi> [ARP]hoijui_g5: you change it ?
<[ARP]hoijui_g5> yes, i can do that
<zerver> thanks
<[ARP]hoijui_g5> anyone agiasnt it?
<[ARP]hoijui_g5> i would preffer gml but i do not care too much
<[RoX]Tobi> I fine with anything
<[RoX]Tobi> next point?
<[ARP]hoijui_g5> yeah
<zerver> mt is a term the average user may understand, gml is not

* We don't build dedicated with all (I assume Tobi can fix this)
* Multithreaded binary should be renamed to spring-mt (hoi)
* Multithreaded binary has "MT" in the version string already

=== engine: fix malformed attack command crashing all players in game ===
<[RoX]Tobi> important enough to completely fix this before release?
<[LCC]jK> don't think so
<zerver> no, but it is incredible how spring lacks error handling
<[LCC]jK> if I understood it correctly, it can happen with nearly any command
<[RoX]Tobi> yes, as far as I have seen
<[LCC]jK> at best the error handling may happen per CMDTYPE
<[CoW]Kloot> and there have been plenty of crashes due to them in the past
<[RoX]Tobi> probably yeah
<zerver> Same with network probably
<[CoW]Kloot> but properly encapsulating Command is a _lot_ of work
<[RoX]Tobi> yup
<[ARP]hoijui_g5> it can be done gradually
<[ARP]hoijui_g5> does not have to be all at once
<[RoX]Tobi> just pasting if (ci->params.size() > X) is easy, but boring :P
<[LCC]jK> it would clutter sim-code, too
<[CoW]Kloot> and with that approach you're never quite sure if you have all cases covered
<[ARP]hoijui_g5> hmm?
<[RoX]Tobi> true that
<[ARP]hoijui_g5> why clutter sim code?
<[ARP]hoijui_g5> it is under Game/
<zerver> Maybe validate already when packet arrives...
<[RoX]Tobi> there are lots of candidate places
<[CoW]Kloot> not really possible
<[CoW]Kloot> since the sim determines context of command params
<[LCC]jK> yeah, it needs to be checked in the same simframe
<[RoX]Tobi> the particular case I fixed was lua widget - the input could there be checked already if there is some table somewhere with data about how many params each command type allows
<[RoX]Tobi> and indeed it needs recheck in sim, but once such data is in place that would be relatively easy
<[RoX]Tobi> anyway, all in all I agree that it's too much work for now to do before rc
<[LCC]jK> I do
<zerver> Maybe change the container type from vector to some other class that throws exception when out of bounds?
<zerver> And then catch exception in sim
<[LCC]jK> much work too
<[LCC]jK> also vectors have such a operator already .at()
<[RoX]Tobi> [LCC]jK: what do you mean with `I do' ?
<[RoX]Tobi> you do agree ?
<[LCC]jK> I agree
<[RoX]Tobi> kk
<[CoW]Kloot> for now we could overload operator [] to do boundschecking
<[CoW]Kloot> since that is used pretty much everywhere
<[LCC]jK> it may cause a noticeable slowdown
<[RoX]Tobi> that would be a bit of a hack (overloading std::vector) but it would work
<[ARP]hoijui_g5> i preffer doing nothign, and then do it right
<[RoX]Tobi> :)
<zerver> Only do it for cmd.params
<[CoW]Kloot> or only in debug builds
<zerver> and then one big try...catch around everything
<[LCC]jK> yeah, for debug builds it would be nice
<[ARP]hoijui_g5> dont think it is usefull in debug builds
<[ARP]hoijui_g5> i thoug the problem is, that this can be exploited?
<[RoX]Tobi> IMO such big try catch will just result in very un-understandable flows, and since it doesn't crash anymore no one will fix it :)
<zerver> The only important thing wrt Sim is that all clients behave the same
<[ARP]hoijui_g5> .. yes, what Tobi said
<zerver> So try catch could be in SimFrame() even
<[RoX]Tobi> besides, I completely don't trust exception handling in C++ (seen too many cases of exceptions passing straight through catch blocks etc.)
<[ARP]hoijui_g5> they say, that since mingw gcc 4.4, dwarf2 exception are good
<[ARP]hoijui_g5> and should not do that anymore
<[RoX]Tobi> then I'll need to upgrade mingw on buildbot ;-)
<[ARP]hoijui_g5> since that, everyone is moving to dwarf2
<[ARP]hoijui_g5> :D
<zerver> Anyway, I can make a class from vector and overload [] and make the try catch thing
<[ARP]hoijui_g5> .. or we do nothing
<[ARP]hoijui_g5> and start a discussion fo a nice way to encapsulate
<[RoX]Tobi> I think I agree with [ARP]hoijui_g5, do nothing until we have good solution
<[LCC]jK> +1
<daftalx> (+1, though i don't get the big picutre yet...)
<zerver> Only good solution may be to clutter sim code with checks
<[ARP]hoijui_g5> if it is encapsulated, checks can be called from wherever, no?
<[ARP]hoijui_g5> easy switching
<[ARP]hoijui_g5> if it is done well
<[LCC]jK> imo a good solution would be to just check all cmds before a simframe
<[RoX]Tobi> all cmds of all units?
<[LCC]jK> maybe it could be optimized somehow to detect if cmds aren't used in that simframe
<zerver> -1
<[RoX]Tobi> I think that will have way bigger performance impact then just checking on every access to operator[]
<[ARP]hoijui_g5> i though we are talkign about the giant command handling switch/if-elseif-elseif .. stuff in Game.cpp?
<[RoX]Tobi> heh, no, the Command::params member
<[ARP]hoijui_g5> ahh
<[RoX]Tobi> and how everything uses it without checking there are enough params
<[RoX]Tobi> either way
<[ARP]hoijui_g5> ahaa..
<[ARP]hoijui_g5> ok
<zerver> we are talking about every cmd.params[] access
<[RoX]Tobi> maybe we better take rest of this out of meeting sometime?
<[ARP]hoijui_g5> mmm
<[LCC]jK> k
<[RoX]Tobi> and just consider it non-blocking for the moment
<[ARP]hoijui_g5> ok..
<[RoX]Tobi> after all it's been like this for ages already :P
<[ARP]hoijui_g5> i have the crashes in CMiniMap::Draw()
<[ARP]hoijui_g5> that shoudl be fixed before release
<[LCC]jK> can be fixed during RC
<[LCC]jK> we will get some more of those issues I assume
<[ARP]hoijui_g5> mm
<[ARP]hoijui_g5> ok
<[RoX]Tobi> ok
<[ARP]hoijui_g5> and AI desync.. same i guess
<[ARP]hoijui_g5> not even sure if it still happens, just got one report so far
<[LCC]jK> yup, that's what RCs are for :)
<[ARP]hoijui_g5> :-)
<[ARP]hoijui_g5> anything else that needs to be done before RC?
<[RoX]Tobi> anything else that blocks RC then?
<[RoX]Tobi> :)
<[LCC]jK> OpenAl32.dll ;)
<[RoX]Tobi> changelog?
<[LCC]jK> oh changelog
<[LCC]jK> good point
<[RoX]Tobi> more things I don't know right now
<[ARP]hoijui_g5> :D
<[LCC]jK> should one person do it? or should each dev fill his stuff into it?
<[RoX]Tobi> each dev IMO, to spread work
<[RoX]Tobi> going through >1000 revisions on your own is booooooooring
<zerver> just copy paste from git :)
<[RoX]Tobi> nah those changelog copied from git are incredibly bad IMO, it should be nice summary
<[RoX]Tobi> and not include all the fix typo here, fix compile there
<[ARP]hoijui_g5> :D the drughead russian guy is priceless :D he still thinks you are talkign to him, jk :D
<[ARP]hoijui_g5> next point?
<[RoX]Tobi> you can see what you did using e.g. git log --author=Name
<zerver> each dev then, hopefully you remember your main changes
<[RoX]Tobi> so what's the plan then, each adds his stuff to change log before next week ?
<[RoX]Tobi> and then we make rc ?
<[ARP]hoijui_g5> ok
<zerver> yes
<[RoX]Tobi> which also provides some time to fix some more bugs, fix the OpenAL thing, maybe do some internal testing, maybe upgrade mingw, etc. :P
<[RoX]Tobi> [LCC]jK, [CoW]Kloot, agree with that?
<[LCC]jK> kk
<[CoW]Kloot> yeah that works too
<[RoX]Tobi> did you have other plan?
<[CoW]Kloot> make RC now, get some early feedback and update changelog in the interim
<[LCC]jK> first OpenAL32.dll needs to be fixed
<daftalx> glitches with the sound ?
<[LCC]jK> so a RC could be tagged already midweek
<[LCC]jK> daftalx, no, it's a dll linking issue on windows builds
<daftalx> k
<[RoX]Tobi> what do we consider RC btw? same as past ones, e.g. ?
<[RoX]Tobi> (that does have complete changelog)
<[RoX]Tobi> or just 'appoint' one of latest test builds from buildbot as RC with post in dev forum ?
<[ARP]hoijui_g5> yeah,,
<[ARP]hoijui_g5> not too official if we alreayd know it has qutie osme bugs that need to be fixed before a release
<[LCC]jK> hmmm mod devs still need to fix their mods, they need a changelog to do this
<[ARP]hoijui_g5> as this.. what you linked.. we though about it as good enough for release
<[RoX]Tobi> yeah
<[RoX]Tobi> that is what RC usually means IMO, "we think it's good enough for release but surely we missed lots of bugs :P"
<[ARP]hoijui_g5> post in dev forum with at least the stuff important for mod devs ?
<[ARP]hoijui_g5> mmm
<[ARP]hoijui_g5> maybe just call it differently then
<[ARP]hoijui_g5> to make clear it will not be released like that
<[CoW]Kloot> the important (mod-breaking, eg the unit spawning changes) points are already on the forum
<[ARP]hoijui_g5> and announce only in dev forum, not news forum
<[RoX]Tobi> k
<[ARP]hoijui_g5> yeah.. but we need to put pressure on mod devs
<[ARP]hoijui_g5> .. maybe have a cross post in mods forum
<[RoX]Tobi> I'll put out a test build asap (tonight or tomorrow) in dev forum, that will just be a random build I select from buildbot
<[RoX]Tobi> and next week we have finished changelog and make real rc, k ?
<zerver> good
<[ARP]hoijui_g5> ahh.. good :-)
<[LCC]jK> no more modinfo.tdf support
<[LCC]jK> no support for LightingCannon(sic) anymore
<[RoX]Tobi> otherwise meeting becomes way too long again :)
<[CoW]Kloot> that was announced even earlier
<[LCC]jK> sure it was announced, but there wasn't a release between
<[LCC]jK> so you can expect that modders fixed their mods yet

* Malformed commands crash is not blocking and will not be fixed now
* The obvoius way to fix the bug bloats the Sim code quite a lot, may need a new approach
* Each dev should update the changelog ASAP
* OpenAL32 issue must be fixed before RC

==GPL (progress)==
<[ARP]hoijui_g5> in a week, AF shoudl release his source
<[RoX]Tobi> <-heres what I have now
<[ARP]hoijui_g5> .. i mean.. does not have to till then, but he said he will, most likely
<[RoX]Tobi> quick modification of the other thread ;-)
<[RoX]Tobi> I'm still messing around with the other/dual license points
<[RoX]Tobi> if you have input (now or later on) you can say it here or pm me later on
<[ARP]hoijui_g5> i would like if we recommended dual licencing over licensing eg under BSD
<[RoX]Tobi> also added it as etherpad on my to do list on the main etherpad
<[ARP]hoijui_g5> as it is more clear then that it is GPL in spring context
<[ARP]hoijui_g5> ahh :-)
<[RoX]Tobi> anyway thats progress for now
<[ARP]hoijui_g5> ok
<[ARP]hoijui_g5> next?
<[RoX]Tobi> you can also add comments in the etherpad if you want

* Work on the license statements is still in progress

==== * OS X (progress)====
<[RoX]Tobi> daftalx, your turn I suppose ;-)
<daftalx> right
<daftalx> so I now have a fully operationnal build of the latest (or almost) source
<[ARP]hoijui_g5> nice :-)
<daftalx> and managed to pull out a portfile this morning
<[ARP]hoijui_g5> whats that?
<daftalx> so now spring can be installed in one line ;)
<[ARP]hoijui_g5> ahh :-)
<daftalx> itÔö£Ôòús the equivalent of rpm / apt-get etc.
<[ARP]hoijui_g5> nice :-)
<daftalx> now i'd like to set up a builbot on my server, as my participation can be very variable at times
<[ARP]hoijui_g5> did you also test GML and headless?
<daftalx> not yet
<daftalx> i have to make a list of stuff to test with you guys
<daftalx> is there any plugin i need to install on top of buildbot btw ?
<[RoX]Tobi> no
<daftalx> ok then, will just need a quick hand in setting up the slave
<[RoX]Tobi> I can help you with that, I'll need to configure master to accept it & to know what it can run on the slave anyway
<[ARP]hoijui_g5> where wil you set it up, your machine?
<daftalx> yeah, got q mqc mini hooked in 24/7
<daftalx> (and a freakin french kb lol)
<[ARP]hoijui_g5> :D
<[ARP]hoijui_g5> no idea what q mqc mini is
<[RoX]Tobi> aegis has also offered a 24/7 mac machine
<[RoX]Tobi> I'll try to also continue setting up buildslave there
<daftalx> used as slave ?
<[ARP]hoijui_g5> hmm :-)
<[RoX]Tobi> with remote slaves you never know how long / when they are online etc. so a bit of redudancy can not hurt
<daftalx> it's a core2duo 2.2GHz with 2GB RAM
<daftalx> agree ;)
<[RoX]Tobi> but he'll probably need instructions on how to build spring from you first :-)
<daftalx> I use it to access my data from anywhere as i travel a lot
<daftalx> well if i manage to push the portfile to macports, he'll be happy
<daftalx> then i can push a portfile for each build type you mentioned (gml / headless)
<daftalx> are these separate git branches ?
<zerver> no
<[RoX]Tobi> no
<[RoX]Tobi> gml and headless are since a week ago or so separate build targets
<[RoX]Tobi> e.g. make spring-gml, make spring-hl
<daftalx> ok, that's perfect actually
<daftalx> so what's your plan for now ? want to go for a .app right away, or use the linux-like alternative for the short-term ?
<[ARP]hoijui_g5> the alternative is gentoo like?
<[ARP]hoijui_g5> downlaoding source and then building, for each client?
<[RoX]Tobi> I don't know how hard either is
<daftalx> well now it's in 3 steps : 1) install xcode (gcc etc.); 2) install MacPorts; 3) hit "sudo install springrts"
<daftalx> that's as simple as i managed to get it
<daftalx> but for every official release i could come up with a full binary, but the dependency libs are still needed..
<daftalx> i'd say it's already a substancial improvement over the exisiting tutorials :)
<[RoX]Tobi> and with .app you have everything at once?
<daftalx> that's the thing, i'll have to look into more details, but there are really a lot of stuff to bundle in
<[RoX]Tobi> ok lets keep with the macports thing for now I'd say
<[RoX]Tobi> indeed it would be a lot better then now already
<[ARP]hoijui_g5> mm
<daftalx> we just have to make sure what release is pushed to the repos
<daftalx> and the repo system allows to build different targets at once
<daftalx> so the gml and headless as well
<[ARP]hoijui_g5> mmm :-)
<daftalx> i can also set up the repo to do a git pull before even compiling...
<daftalx> that would be a special "springrts-devel" package then
<[ARP]hoijui_g5> .. sounds good.. you will know what makes sense
<[RoX]Tobi> hmm I gtg already (meeting took too long again ;-))
<daftalx> well the only thing is that versions should be the same over all oses
<daftalx> and the lobby still has issues
<daftalx> but working on it
<zerver> which lobby?
<[ARP]hoijui_g5> ok.. bye Tobi!
<daftalx> SL
<[RoX]Tobi> if I've time I'll PM you after dinner daftalx
<[LCC]jK> bye
<zerver> ok
<[RoX]Tobi> (and you have time too)
<daftalx> ok bye
<[RoX]Tobi> then we can see about buildbot
<daftalx> ok cool
<zerver> there is also qtlobby which you may compile directly on mac i think
<daftalx> thought that one was abandoned
<[RoX]Tobi> wrt buildbot, short update to handle that point too: stacktrace translator is running ( ), buildbot running ok too, still need to work on something to force builds properly
<zerver> abandoned, well no active dev atm but it works fairly ok
<[ARP]hoijui_g5> mmm :-)
<[RoX]Tobi> will read rest of meeting in log :)
<[ARP]hoijui_g5> QTLobby is nto the way to go
<[RoX]Tobi> oh, and unfortunately next week at this time I can not be here
<daftalx> actually SL compiled at some point, but the wxWidgets is the tricky part
<[ARP]hoijui_g5> it lacks too much
<[RoX]Tobi> laters
<[ARP]hoijui_g5> eg.. AI
<[ARP]hoijui_g5> byee
<[CoW]Kloot> laters
<daftalx> they're hacking their build every now and then
<daftalx> bye
<daftalx> qt has no QI support ???
<daftalx> AI
<zerver> nope
<daftalx> grr
<zerver> but not everyone likes to play with AI
<zerver> im using qtlobby now
<daftalx> how about sync problems?
<[ARP]hoijui_g5> hm?
<zerver> of the lobbies i tried it is the one with least flaws for my specific requirements
<[ARP]hoijui_g5> the lobby can not cuase sync prblems
<daftalx> i heard about a few issues about unitsync
<daftalx> but i may be confusing (that was early last week)
<[ARP]hoijui_g5> yeah... but unitsync does not cause desyncs
<daftalx> i'll have a look into qtlobby then, but i'll keep working on SL qs well
<[ARP]hoijui_g5> it is not used during a game
<[LCC]jK> lobby syncing and ingame syncing are not the same
<daftalx> ok, then it's a lobby sync issue
<[ARP]hoijui_g5> unitsync just has a very stupid name
<daftalx> yeah figured..
<[ARP]hoijui_g5> it should be called ExternalSpringDataAccessLib or somethign liek that
<[ARP]hoijui_g5> anythign else about OS X?
<daftalx> but it did work once:
<[LCC]jK> who merges the changes into master?
<daftalx> right no changes for OS X
<daftalx> and i have full sound support and everything
<daftalx> so it's cool
<[LCC]jK> O_O
<zerver> great
<daftalx> the lobbies are more problematic
<[ARP]hoijui_g5> mmm :-)
<daftalx> so by next time i'll try the gml and headless builds
<[ARP]hoijui_g5> nice :-)
<daftalx> and setup the buildbot with Tobi
<[ARP]hoijui_g5> we are stll simplifying the headless build
<daftalx> well...guess i'm done for now
<daftalx> can't be of much more help for the moment

* OSX compiles without any changes (!)
* OSX buildbot slave will be set up (Tobi and daftalx)
* OSX needs to test the MT and HL builds (daftalx)
* qtlobby might be an alternative to springlobby on OSX
* unitsync is a confusing name and may need to be changed

==== * MT official build (progress) ====
<daftalx> i'm only dicovering the code
<[ARP]hoijui_g5> :-)
<[LCC]jK> we could need a new dev btw ;)
<[ARP]hoijui_g5> yeah.. daf, you want to be spring dev.. officially?
<[ARP]hoijui_g5> with commit access to main repo?
<[ARP]hoijui_g5> (girls love it!)
<zerver> so MT integration in the installer is basically done now?
<daftalx> well... i'd say until i don't need to commit stuff i don't need
<daftalx> though modding the Mac OS forum could be a good start
<daftalx> but hell yeah, whatever :p
<[ARP]hoijui_g5> :D
<daftalx> the lobby guys need me more apparently :)
<[ARP]hoijui_g5> mm ok
<[LCC]jK> zerver, your any progress with non-drawable contexts
<[ARP]hoijui_g5> well.. tell us if you have osmething to commit
<[LCC]jK> -your +?
<[ARP]hoijui_g5> zerver, i did the integration code for the installer, but i never loked at a genrated installer ;-)
<[ARP]hoijui_g5> did you?
<zerver> no :)
<zerver> jK: you mean glShareLists?
<[LCC]jK> yup
<zerver> i have not done anything on that side
<[LCC]jK> k
<zerver> it will complicate some things if there are still contexts in which gl is not allowed
<zerver> For instance, can you do actual rendering in Sim now?
<zerver> or would that fail?
<[LCC]jK> you can render it a displaylist
<[LCC]jK> *in
<zerver> Indeed, but I mean rendering to screen
<[LCC]jK> no, those are disallowed even in singlethreaded
<zerver> OK
<zerver> So basically I could use glShareLists but then I would have to disable most of GML
<zerver> Which I might do anyway because the gain is so small
<[LCC]jK> yeah, you could even compile display list in the other threads and use those instead of GML
<[LCC]jK> e.g. for terrain rendering
<zerver> I will look at it
<zerver> next point?

* MT and HL are integrated in the installer but installer not tested yet
* Use glShareLists to improve MT build compatibility with mods (zerver)

== Buildbot progress ==
<[LCC]jK> finished already?
<daftalx> i'm interested... especially if it gets "simple"
<[ARP]hoijui_g5> i think Tobi is pretty far there, yes
<[ARP]hoijui_g5> zydox told me he incorporated debug symbol translation already
<[ARP]hoijui_g5> (only werks for crashes from builds of new buildbot)
<[ARP]hoijui_g5> lets define somewhen during the week, when to have next meeitng?
<[ARP]hoijui_g5> as Tobi is not here, and wont be at same tiem next week

* There is good progress (at least we think so)
* Debug symbol translation is working

=== Next meeting ===
<[LCC]jK> yeah, next week will be 100% RC
<zerver> ok
<[LCC]jK> and some of you requested a longer delay
<daftalx> unfortunately i'll be off next week
<[LCC]jK> so may decide this during the week while RC is made
<[ARP]hoijui_g5> daftalx, off all weekend?
<daftalx> actually away from this wed to next tue
<daftalx> my first holiday week since christmas...
<[ARP]hoijui_g5> ok
<[ARP]hoijui_g5> :-)
<zerver> end of meeting then
== End ==

* Next week will be largely dedicated to work on the release candidate

Yup, sorry for having to leave before end (I should really force the meetings to be a bit shorter ;-))

New since last week:
  • Additional version string is properly inserted.
  • Already stripped binaries aren't stripped again (resulted in overwriting the debug symbols with an nearly empty file)
  • Restructured how files are uploaded. It's always config/branch/rev now. Filenames are always [config]{branch}rev_name.7z and [config]{branch}rev_name_dbg.7z, where [config] and {branch} are left away if they are [default] resp. {master}. This makes first part of filename identical to version string on this buildbot. (Easy for stracktrace translation.)
  • MT, headless and spring-dedicated binaries and debugging symbols are uploaded now.
  • Stacktrace translation API is fully functional (though some more features planned): . Documentation should explain it all.
  • That's it if I recall correctly.
Buildbot overview:
Buildbot status display: (Maybe I'll set up proxying for this later on so it can live on port 80.)

Excellent, sounds like things are really going well! I'll try to find time to do some testing next week, I should be available then.

not many OSS projects that I know of keep the development this active and clear. Thank you!
