== who makes minutes? == <zerver> ok, I will make em
== Release plan == <zerver> we should release on friday <abma> why friday? <abma> or... why not? <jk> releases on fridays always failed <zerver> im kidding, but we need a few days to nuke some remaing crashbugs <jk> in 99% there are bugs and spring is unplayable for 1week <abma> ok <zerver> :)
== Sync == <abma> [RoX]Tobi: maybe we should talk first about the sync problem? <tobi> yeah, don't know how many noticed <tobi> but on Fedora 15 I noticed neither distro built package nor self built package syncs with release <jk> btw I would still find a better solution for this: https://github.com/spring/spring/commit ... 6#comments <tobi> also a yesterday or so a similar bug was reported in Debian <jk> -would +want <tobi> [AG]abma said it didn't sync in recent Ubuntu either <jk> GCC4.6 ... <tobi> koshi synced with gcc 4.6 <jk> I wonder why so many distros switched so early <tobi> self built gcc 4.6 and self built spring <jk> gcc build with -march/mtune? <tobi> in any case it will be a major issue <tobi> not in the output of -v afaihs <tobi> Configured with: ../configure --prefix=/usr --mandir=/usr/share/man --infodir=/usr/share/info --with-bugurl=http://bugzilla.redhat.com/bugzilla --enable-bootstrap --enable-shared --enable-threads=posix --enable-checki --with-system-zlib --enable-__cxa_atexit --disable-libunwind-exceptions --enable-gnu-unique-object --enable-linker-build-id --enable-languages=c,c++,objc,obj-c++,java,fortran,ada,go,lto --enable-plugin --enable-java-awt=gtk --dis -with-java-home=/usr/lib/jvm/java-1.5.0-gcj-188.8.131.52/jre --enable-libgcj-multifile --enable-java-maintainer-mode --with-ecj-jar=/usr/share/java/eclipse-ecj.jar --disable-libjava-multilib --with-ppl --with-cloog --with-tune=generic h=i686 --build=i686-redhat-linux <tobi> with self built gcc 4.5 I desync too <tobi> didn't try any older yet <tobi> so I actually think it isn't gcc or isn't only gcc <jk> k <jk> needs a few debug matches then <tobi> yeah, syncdebug and/or more matches on slightly older platforms to see where it started breaking exactly <zerver> instant desync ? <abma> no <tobi> nearly instant (within a few min) <jk> assimp can be a cause <tobi> I observed this in current release <tobi> so no assimp involved yet <jk> k so 300,000 LOC left ^^ <abma> in other words 0.82.7.1 desyncs, too when built on ubuntu 11.04 <tobi> and abma and I sync (i.e. Ubuntu 11.04 vs Fedora 15) <jk> time to setup an enviroment for a syncdebug build <tobi> ya guess so <tobi> suppose I'll make a mantis too <zerver> k, so this is the biggest obstacle for the release <abma> next week i can help with compile/testing... currently i've only a bad computer <tobi> abma: did ubuntu 11.04 package sync? <abma> stable ubuntu 11.04 package does sync <tobi> ok <abma> i don't know if there is a package of spring/master <tobi> I understood from koshi that is gcc 4.5 <tobi> strangely his 4.6 seemed to sync too (desynced from us at least) <tobi> [AG]abma: so what was it again what we tested? self-built spring with packages gcc 4.6 ? <tobi> *packaged <abma> the packaged 0.82.7.1 in ubuntu 11.04 syncs <tobi> yeah <tobi> but you also tested something that made you desync, right? <abma> my spring master compiled with gcc 4.6 synced with tobi, but didn't sync with koshi <abma> self-compiled stable didn't sync <tobi> k <abma> it took some time until it desynced <tobi> and it was a gcc 4.6 package? <abma> self-compiled was with gcc 4.6 <abma> i also tried 4.5 that desynced, too <tobi> yeah but I mean, did you compile gcc 4.6 yourself <abma> no <tobi> or did you use a gcc-4.6 package? <abma> that was from a ppa <tobi> ok <tobi> you can check here: http://springrts.com/mantis/view.php?id=2459 <tobi> maybe I still need to try to build gcc 4.5 with gcc 4.5 and then build spring with that <tobi> instead of trying gcc 4.5 built with gcc 4.6 :) <abma> hopefully we didn't mix stuff <tobi> i.e. more complete bootstrap <abma> next week i can check with ubuntu 10.04 again + gcc 4.6 <tobi> sucks to trace this down since I didn't even play online since before I upgraded to F14 <jk> I will try to setup a syncdebug enviroment today <tobi> so could have even been broken in F14/gcc 4.5 already <tobi> ok <tobi> with master? <jk> with git <jk> switching between branches/tags shouldn't be a problem once I set it up <tobi> ok <jk> gcc switching could be a bit more compilicated, but should be doable too <jk> -i <zerver> if there is something I can help with, shout, but I have no unix box <zerver> otherwise imma continue the crashbug hunt <tobi> I guess continuing other things is better choice in this case :) <zerver> next?
== Remove remaining .n's or re-add them? http://springrts.com/mantis/view.php?id=2456 == <abma> [LCC]jK: are there pro/cons for that? <abma> con is, that some games don't work with spring/master <tobi> I don't really mind what will be the solution to this <jk> I prefer removing them, but if doing so we should remove ALL of them <abma> is that.. ehm.. doable with something grep-like? maybe grep for "n" ? <abma> + how to fix the lua code? <tobi> are there cases where the returned table is not an array? <jk> sure <tobi> for all arrays you can replace it with # operator <tobi> for non-arrays you need to write a loop / call a function to count the elements in the table <jk> but it for non-arrays the .n isn't used afaik <jk> -it <tobi> ok <zerver> so is adding the # acceptable or will modders raeg about this change? <jk> some very old widgets may fail <jk> the amount of incompability should be very limited <abma> especially unit-morph... but afaik fix should be very easy <abma> the fix will work on current release? <abma> if so, i'll see no problem with this change <abma> with "the fix", i mean the the fix for the lua-script <tobi> [AG]abma: yeah should work
== Can the 0.8* branches be removed? guys still seem to start with non-master-branches to == <tobi> IMO they can go, we can just make new branches of tags if desired <abma> ok, then i'll anoy some of the game-devs about that, if i see this problem <zerver> k <tobi> just keep that branch I made past week, 0.82.7.1-gcc-4.6 <abma> ok, i'll ask hoijui about that, he is the git-guru + remove then <jk> btw abma that `guy` intentionaly used the 0.82 branch <abma> so.. hmm <abma> yes, this is why i want it to make a bit "harder" to use an old branch/tag <jk> 1. he wanted to play online with his build 2. he didn't wanted any merge conflicts <zerver> :) <abma> so..
== Next meeting == <abma> shall we start half an hour later? <zerver> if we do, will it have the desired effect? <abma> i don't know :-/ <abma> so, kloot, zerver: why where you late? would starting half an hour later help? :) <kloot> I just had late dinner :) <abma> i was late because i was busy in the garden a bit and forgot time :D <zerver> it is national day of Sweden today, late dinner with champagne <abma> [RoX]Tobi: [LCC]jK: what do you think? imo, if it fails next week, we keep it at 21:00 <tobi> so next week 21:30 ? <jk> fine <abma> ok <zerver> sweden and some other countries use "academic quarter" http://en.wikipedia.org/wiki/Academic_q ... _timing%29 <zerver> so it is deeply rooted in my mind that being 15mins late is OK <abma> so: zerver: next week its 21:00 for you <zerver> lol <abma> ok, fine <zerver> fine
== Anything else? (WVTTK) == <zerver> i'd like jk to clarify the fixme https://github.com/spring/spring/commit ... d77d372d4a <jk> you put the set_threadnum in a if-clause - very likely because if loadscreen is not threaded it would get called twice from the same thread causing undesired behaviours <jk> now this should be solved in set_threadnum itself <jk> so you can call it multiple times from the same thread w/o any undesired behav. <jk> e.g. Watchdog works fine if you do so <zerver> but CGame::LoadGame is only called once <jk> doesn't matter <jk> set_threadnum is unsafe currently, don't try to fix it with hacks <zerver> sry, still don't get it <zerver> and where is the hack? am I now allowed to set a thread number for that loading thread? <jk> sure you are, but please without making mt_loading public <zerver> OK, so GetLoadingMT() <jk> no <jk> fix set_threadnum! <jk> make set_threadnum work when called twice from the same thread, so you don't need a if-clause at all! <zerver> i don't see how, the loading thread needs a number <jk> save multiple numbers per thread? <zerver> you mean, i should fix the set_threadnum so only the first call has any effect? <jk> or that <jk> there are many solutions <zerver> kk,will check <zerver> but without that if clause, it is a bit ugly imo, because that is not the loading thread unless mt_loading is true <jk> it is the loading thread <tobi> can't the thread num be set at the place the thread is created or so? <jk> it's always the loading thread that calls that function <zerver> no, in that case loading thread == main thred <jk> but sometimes loading thread & mainthread are the same <jk> still it is the loading thread <zerver> kk, fine <zerver> im a bit fraid my attempts will produce a much worse solution <zerver> it will require some form of TLS or indexing by thread ID, and with the portability issues that come with that... <jk> depends on your needs <jk> if you do this: <zerver> you mean, i should fix the set_threadnum so only the first call has any effect? <jk> nothing special is needed <jk> if you save a list of numbers, it becomes a bit more complex <zerver> set_threadnum is the "root" for all TLS that GML uses <zerver> and now I may have to make another separate TLS mechnism <zerver> im just thinking this just delays our release <jk> so get_threadnum isn't safe either? <jk> -> if called from a unregistered thread it returns bogus? <zerver> yep <zerver> garbage <zerver> it uses some ASM and the FS register <jk> you still can use posix threadids <jk> setthreadnum is called such rarely <jk> you could even play with gcc's `thread static` vars <zerver> ok, index a map by posix thread id <zerver> __thread etc isnt portable <jk> on gcc it is and afaik it is part of c++0x <jk> but yeah, MSVC is slow and special ... <zerver> :)
I got desyncs on Fedora 15 64bit with current version of Spring from fedora repo. I thought that this issue only of 64bit version. I am very happy that you know about this problem and I hope you will fix it Thanks!
