Which is very good, if I +may say so again! :-) + +Of course, everyone is invited to contribute here! + +I want to give the following methodology a try, instead of only having +email/IRC discussions -- for the latter are again and again showing a tendency +to be dumped and deposited into their respective archives, and be forgotten +there. Of course, email/IRC discussions have their usefulness too, so we're +not going to replace them totally. For example, for conducting discussions +with a bunch of people (who may not even be following these pages here), email +(or, as applicable, the even more interactive IRC) will still be the medium of +choice. (And then, the executive summary should be posted here, or +incorporated into your proposal.) + +Also, if you disagree with this suggested procedure right away, or at some +later point begin to feel that this thing doesn't work out, or simply takes too +much time (I don't think so: writing emails takes time, too), just say so, and +we can reconsider. + +Of course, as this wiki is a passive medium rather than an active one as IRC +and email are, it is fine to send notices like: *I have updated the wiki page, +please have a look*. + +One idea is that your proposal evolves alongside with the ongoing work, and +represents (in more or less detail) what has been done and what will be done. +Also, we can hopefully use parts of it for documentation purposes, or as +recipes for similar work (enabling other programming languages on the Hurd, for +example). + +For this, I suggest the following procedure: as applicable, you can either +address any comments in here (for example, if they're wrong :-), or if they +require further discussion; think: *email discussion*), or you can address them +directly in your propoal and remove the comments from here at the same time +(think: *bug fix*). + +Generally, you can assume that for things I didn't comment on (within some +reasonable timeframe/upon asking me again) that I'm fine with them. Otherwise, +I might say: *I don't like this as is, but I'll need more time to think about +it.* + +There is also a possibility that parts of your proposal will be split off; in +cases where we think they're valuable to follow, but not at this time. (As you +know, your proposal is not really a trivial one, so it may just be too much for +one person's summer.) Such bits could be moved to [[open_issues]] pages, +either new ones or existing ones, as applicable. + + +# POSIX Threads Signal Semantics + + * Great! [[tschwinge]] had a brief look, and should have a deeper one. + + * If [[jkoenig]] thinks it's mature enough: should ask Samuel to test this + (that is, only the refactoring patches for starters?) on the buildds. + + * Then: should ask Roland to review. + + * Documentations bits should probably be moved to [[glibc/signal]]. + + +## libthreads (cthreads) Integration + + * [[tschwinge]] suggests to leave them as-is? + + +## [[libpthread]] integration + + * To be done. + + +# Java + + * [[tschwinge]] has to read about RMI and CORBA. + + +# Joe-E + + * For later. + + +# GCJ + + * [[tschwinge]] has the feeling that Java in GCC (that is, GCJ) is mostly + dead? (True?) + + * Thus perhaps not too much effort should be spent with it. + + If the POSIX threads signal semantics makes it going, then great, otherwise + we should get a feeling what else is missing. + + +# OpenJDK + + * All in all, [[tschwinge]] has the feeling that a working OpenJDK will be + more useful/powerful than GCJ. + + * We need to get a feeling how difficult such an OS port will be. + + * [[jkoenig]] suggests OpenJDK 6 -- should we directly go for version 7 + instead? + + * What are the differences (regarding the OS port) between the two + versions? Or this there something even more recent to be worked upon, + for new OS ports? + + * Perhaps the different versions' OS port specific stuff is not at + all very different, so that both v6 and v7 could be done? + + * They seem to have a rather heavy-weight process for such projects: confer + , + for example. Do we need this, too? + + +# Eclipse + +OK for testing -- but I'd very much hope that it *just works* as soon as we +provide the required Java platform. + + +# Java Bindings + + +## Design Principles + + * Generally ack. + + +### MIG + + * Hacking [[microkernel/mach/MIG]] shouldn't be too difficult. + + * (Unless you want to make MIG's own code (that is, not the generated + code, but MIG itself) look a bit more nice, too.) ;-) + + * There are also alternatives to MIG. If there is interest, the following + could be considered: + + * FLICK ([[!GNU_Savannah_task 5723]]). [[tschwinge]] has no idea yet if + there would be any benefits over MIG, like better modularity (for the + backends)? If we feel like it, we could spend a little bit of time on + this. + + * For [[microkernel/Viengoos]], Neal has written a RPC stub generator + entirely in C Preprocessor macros. While this is obviously not + directly applicable, perhaps we can get some ideas from it. + + * Anything else that would be worth having a look at? (What are other + microkernels using?) + + +### `mach_msg` + + * Seems like the right approach to [[tschwinge]], but hasn't digested all the + pecularities yet.
