Windows build of Leyden EA
by ski n 04 Sep '24

04 Sep '24

I just watched the presentation at JVMLS on the status of project Leyden on YouTube: https://www.youtube.com/watch?v=OOPSU4LnKg0 In the talk, they pointed at the EA that came out last June. Currently, only Linux and Mac builds are available. When will the next EA come available, and will this also contain a Windows build? Raymond

PR with static-jdk launcher
by Magnus Ihse Bursie 03 Sep '24

03 Sep '24

Hi, I just wanted to let you know that there is now a PR with an initial implementation of a static java launcher: https://github.com/openjdk/jdk/pull/20837 Some noteworthy limitations: 1) Support for hiding local symbols in static libraries are not yet implemented. This mean that there are symbol clashes between some libraries. As a result, I have temporarily disabled a few libraries. This in turn means that the native code is not complete, so not all JDK functionality is present. How much is missing depends on which platform you run. 2) Only the java launcher is present, no other JDK launchers (including javac) are present. This means that it is not possible to run JTReg tests. I have an idea on how to address this in the future. 3) On Windows, changes need to be done in the launcher code; similar to what has been done for Linux and macOS. As a result of this, the static launcher builds just fine, but crashes at startup. I don't think it is hard to fix, but I have not prioritized this. The reason is that the inclusion of a working static launcher for macOS and Linux will help the Hermetic Java project along, and the Windows launcher can be fixed in the meantime. 4) This is not tested on AIX nor any other platforms apart from Linux, macOS and Windows. It is tested with both gcc and clang on Linux. 5) There are still a lot of untidy and badly structured code surrounding static libraries. I hope to address some of this mess as follow-up work. 6) This PR does not address the issue that all native files are compiled twice. That is a completely orthogonal problem to this. /Magnus

Some offhand questions

Thank you Dan, John, for the detailed answers. > Did you have other thoughts on how such a score could be computed? I have some ideas, but for now I was just curious whether the group would think this is something that makes sense. > [...] That means we should work on code caching first, then work on managing/curating/filtering/sizing the AOT code cache. Sounds good to me. Thanks, César.
