To make Brian and me committers on the bsd-port project will require a community vote with a 2 weeks voting time, yes. Unless Brian already is an OpenJDK Author (that is, has an OpenJDK account), getting the account created after the vote, has in the past been a long wait for the OpenJDK ops to do their thing as well. :( So the quickest and easiest way, at least if we're just talking a few number of patches, is that you shepherd them in. > > FWIW, in terms of taking responsibility, I've been regularly updating the > repos for jdk8 and jdk7 for a couple of years.

I think "regularly building" is kind of the basic they're looking for here, and maybe such a promise is good enough to get my build changes into the mainline. Apparently the FreeBSD foundation has a license to use the official TCK test suite. Getting a port to completely pass the TCK is likely to be quite some work, but if it does it can be integrated as a core supported platform in the JDK9 mainline (and then, automatically, in future versions of the JDK). Maybe it's not even a requirement to pass the full TCK for a community effort. Perhaps it's fine to just run the TCK sort-of regularly and tracking the results so that the number of failures does not drastically increase, and having some kind of long term goal/vision of having zero TCK failures. But I'm not sure about these things. We should probably involve Dalibor Topic in that discussion. /Magnus > > - Greg > >>> On Jan 31, 2016, at 3:00 AM, Magnus Ihse Bursie <magnus.ihse.bursie@oracle.com> wrote: >>> >>> On 2016-01-31 11:54, Magnus Ihse Bursie wrote: >>>> Hi, >>>> >>>> [TL;DR: I'm offering patches to compile JDK 9 on FreeBSD, but it's not clear where to put them, or how.] >>>> >>>> I'm working at Oracle on the OpenJDK build team and is responsible for large parts of the build system of OpenJDK. Lately, I've been playing around with FreeBSD (and other BSDs) in my free time, and I've written a patch that will add build system support for FreeBSD, OpenBSD and NetBSD in JDK 9 (tracked in https://bugs.openjdk.java.net/browse/JDK-8147795). >>>> >>>> I started writing this when I realized that the jdk9 branch in the OpenJDK bsd-port repository did not contain any BSD-specific changes at all, and the old JDK 8 changes will not readily be portable, due to major changes in the build system between JDK 8 and JDK 9. >>>> >>>> I thought it would be a no-brainer to integrate these changes into the JDK 9 mainline, so they would be in place for whenever you guys would start to attack porting the code base. However, some of my collegues thought otherwise. The end result, I think, is that they wanted to see someone (not necessarily a company, the FreeBSD organisation for instance seemed to be okay), to step forward and say "we take responsibility for the BSD port", and give some kind of commitment to actually use these build changes in producing a viable port. You can read the mail conversation here: http://mail.openjdk.java.net/pipermail/build-dev/2016-January/016421.html >>> I forgot to add that I'm willing to help with build issues for the BSD port, as far as my (like everybode else's) limited free time allows me.

Having the code in the mainline does not mean that it gets tested automatically, but it means that it will be part of e.g. refactoring, that would otherwise break a downstream patchset. >>>> >>>> I cc:ed this conversation to the bsd-port-dev@openjdk.java.net mailing list, but never got any kind of official response there.

And there's a second patch, which fixes broken C/C++/Java code and results in a product that can at least run "javac HelloWorld", but this is not yet clean enough for integration anywere, at least not the JDK 9 mainline. (I don't know enough of the BSD internals to fix all problems, so there's some "#if 0" code here and there.) >>>> >>>> /Magnus >>>> >>>> _______________________________________________ >>>> freebsd-java@freebsd.org mailing list >>>> https://lists.freebsd.org/mailman/listinfo/freebsd-java >>>> To unsubscribe, send any mail to "freebsd-java-unsubscribe@freebsd.org" >>> _______________________________________________ >>> freebsd-java@freebsd.org <mailto:freebsd-java@freebsd.org> mailing list >>> https://lists.freebsd.org/mailman/listinfo/freebsd-java <https://lists.freebsd.org/mailman/listinfo/freebsd-java>; >>> To unsubscribe, send any mail to "freebsd-java-unsubscribe@freebsd.org <mailto:freebsd-java-unsubscribe@freebsd.org>" >> _______________________________________________ >> freebsd-java@freebsd.org mailing list >> https://lists.freebsd.org/mailman/listinfo/freebsd-java >> To unsubscribe, send any mail to "freebsd-java-unsubscribe@freebsd.org"
