This is the complete list I need from repoman side: =dev-java/icedtea-bin-7.2.6.3 =dev-util/patchelf-0.8 =dev-java/icedtea-web-1.5.1-r1 =dev-java/icedtea-sound-1.0.1 =media-fonts/lklug-0.6 (In reply to Agostino Sarubbo from comment #2) > This is the complete list I need from repoman side: > > =dev-java/icedtea-bin-7.2.6.3 > =dev-util/patchelf-0.8 > =dev-java/icedtea-web-1.5.1-r1 > =dev-java/icedtea-sound-1.0.1 > =media-fonts/lklug-0.6 Sorry, I forgot that I'd only masked those flags against icedtea and not icedtea-bin and I also missed those additional two packages. I was about to post the same list myself so please go ahead. I'll check more carefully in future. I am trying to build dev-java/icedtea against dev-java/icedtea-bin by way of having something to directly test with. It keeps failing on running out of memory. This is because it self-imposes some memory constraints: -J-Xmx1792m -J-Xms1792m -J-XX:PermSize=32m -J-XX:MaxPermSize=160m when it could be using all 8 gigabytes of RAM. Is there some way of raising these constraints to fit the system icedtea is being built on?

Why do you think icedtea isn't keyworded for ppc64? :P That isn't the main reason, otherwise I would have patched around it, but I have raised this issue with upstream already. Also note that by the time it gets to building the docs, it is using the newly-built icedtea instead of the one used to build initially, unless you disabled jbootstrap. The requirements tend to gradually rise over time and while upstream does test these things, they are using HotSpot rather than the lesser-tested CACAO, so they rely on us to let them know if it doesn't work any more. If you don't specify any limit then HotSpot will allocate 1/4 of the total RAM, up to a maximum of 2GB. Limits are therefore specified here to aid people with say 2GB, which would be sufficient if HotSpot didn't only use 512MB of it. In this particular case, upstream CACAO actually defaults to a max heap of 128MB! I patched this to give similar behaviour to HotSpot as too many ebuilds were dying as a result but on testing it just now, I have found that manually requesting more than 2GB causes the VM to die horribly. I'm pretty certain I tested this thoroughly so maybe something has changed. I will investigate and report back ASAP. Out of interest, do you have your own ppc64 hardware? You mentioned 8GB but timberdoodle has 16GB. (In reply to James Le Cuirot from comment #5) > In this particular case, upstream CACAO actually defaults to a max heap of > 128MB!

It dies if you specify any letter for -Xmx other than "m" or no letter at all, with or without my patch. Not my fault then! I'll look closer later.

You mentioned 8GB but > timberdoodle has 16GB. Yes. Or else, why would I be on that architecture team? It appears to happen especially often with C*FLAGS=".. -g", where the memory ceiling is hit more quickly. Okay, my investigation found that CACAO doesn't support specifying the heap size in gigabytes like HotSpot does. It also uses a signed 32-bit integer to deal with this, resulting in horrendous overflows that aren't immediately apparent. If you ask for 4097MB, it actually allocates 1MB! I have created patches for both these issues, which I will submit upstream, but I'd like to try them out locally a bit more before I include them in a new stable release here. jer, your issues with building icedtea are more to do with icedtea's build process than icedtea-bin. Keep in mind that icedtea:7 isn't even keyworded for ppc64 and we never mark it stable anyway. I know you also filed bug #569152 but the fact is that CACAO isn't guaranteed to work with everything. With all that in mind, I'd like to now proceed with getting this stable, especially as I'm keen to press on with the Java 6 removal. icedtea-bin-7.2.6.3 is vulnerable so this request is now for icedtea-bin-7.2.6.4. It seems that I wasn't able to convince you to stabilize Java 7 on ppc64 and that's perfectly understandable, CACAO evidently wasn't working as well as any of us wanted it to. I've therefore changed tack and focused my efforts on Java 8 instead. icedtea-bin-3.0.0_pre08 has been available to ~ppc64 for 3 weeks now. As soon as it was added, I built almost every Java package keyworded for ppc64 or ~ppc64, over 200 of them, to really put it through its paces. Only a small handful failed and some of those were simply broken regardless of Java 8. I've already fixed all but one of these problems. The remaining one (qdox) cannot be fully resolved until after this stabilisation happens. Please don't be put off by the fact that this is a prerelease. Remember that icedtea is primarily a build process and that the OpenJDK being built is more or less the same OpenJDK that Oracle has based their releases on for ages. Since this is icedtea-bin, the build process isn't even a factor here so this should not be a cause for concern. As far as runtime behaviour goes, it is certainly not plagued by any of the issues we saw with CACAO or the race condition I saw with Java 7's HotSpot. As stated earlier, I am very keen to close this out because it will allow us to finally remove Java 6. If you're wondering about the version number, upstream were keen to correct our divergence from their scheme. icedtea 3 is for Java 8 and we have hinted at that in the SLOT, which is still 8. Given that almost all packages depend on virtual/jdk rather than icedtea directly, we don't see this as a problem. So ppc64 team, please stabilize: =app-eselect/eselect-java-0.2.0 =dev-java/icedtea-bin-3.0.0_pre08 =dev-java/icedtea-sound-1.0.1 =dev-java/icedtea-web-1.6.1-r1 =dev-util/patchelf-0.8 =media-fonts/lklug-0.6 It might be a good idea to wait for pre09 which will have the latest security updates, matching the current proprietary Oracle JDK in Gentoo (u72). This is nearly done. I'm just doing some comparisons to weed out unnecessary differences between the IcedTea trees and the upstream ones.

This has now been done so ppc64 team, please proceed: =app-eselect/eselect-java-0.2.0 =dev-java/icedtea-bin-3.0.0_pre09 =dev-java/icedtea-sound-1.0.1 =dev-java/icedtea-web-1.6.1-r1 =dev-util/patchelf-0.8 =media-fonts/lklug-0.6 There's been a revision bump to icedtea-bin-3.0.0_pre09-r1 because I forgot to remove the dependency on libgif.so.4, which is a problem for unstable users on giflib-5. I have added the other architectures now but I do not wish to stabilize these yet. ppc64 team, please proceed. For the record, ago says we need these as well, which is fine. =virtual/jdk-1.8.0-r2 =virtual/jre-1.8.0-r1 Thanks for sorting this, ago! |
