RFR: 7903239: ofAddress factory of function pointer type is wrong for struct returns
by Marko 02 Jan '24

02 Jan '24

When generating the lambda inside the `ofAddress` factory, it is missing the `SegmentAllocator` needed when the function returns a struct. This is [implemented for regular functions](https://github.com/openjdk/jextract/blob/0582eaf1b4cdba95f0ee8c2…, but not for function pointers. ------------- Commit messages: - 7903239: ofAddress factory of function pointer type is wrong for struct returns Changes: https://git.openjdk.org/jextract/pull/58/files Webrev: https://webrevs.openjdk.org/?repo=jextract&pr=58&range=00 Issue: https://bugs.openjdk.org/browse/CODETOOLS-7903239 Stats: 47 lines in 3 files changed: 44 ins; 2 del; 1 mod Patch: https://git.openjdk.org/jextract/pull/58.diff Fetch: git fetch https://git.openjdk.org/jextract pull/58/head:pull/58 PR: https://git.openjdk.org/jextract/pull/58

RFR: Add Dockerfile, zero-dep reproducible builds
by Gavin Ray 02 Jan '24

02 Jan '24

As title says, adds a Dockerfile that will fetch all necessary deps and build `jextract` for you on Ubuntu 22.10 It would be nice if some official JDK organization could put this on their Dockerhub, so that users could just do: $ docker run --rm -it openjdk/jextract:latest I've pushed it to my personal Dockerhub, so if anyone would like to test it out, you can use the README directions but prepend `gavinray/` before the image name: $ echo "struct Foo { int a; long b; }; int use_foo(struct Foo foo);" >> sample.h $ docker run --rm -it -v ${PWD}:/tmp/jextract \ gavinray/jextract:latest \ -I /tmp/jextract \ --source \ -l libfoo \ --output /tmp/jextract/generated \ --target-package com.example \ ------------- Commit messages: - Add Dockerfile, zero-dep reproducible builds Changes: https://git.openjdk.org/jextract/pull/74/files Webrev: https://webrevs.openjdk.org/?repo=jextract&pr=74&range=00 Stats: 75 lines in 2 files changed: 75 ins; 0 del; 0 mod Patch: https://git.openjdk.org/jextract/pull/74.diff Fetch: git fetch https://git.openjdk.org/jextract pull/74/head:pull/74 PR: https://git.openjdk.org/jextract/pull/74

Re: New candidate JEP: 434: Foreign Function & Memory API (Second Preview)
by Duncan Gittins 28 Oct '22

28 Oct '22

Continuing the theme of Gavin's request, I think you might get more people to try out jextract and Panama if there were easy to find download links in https://jdk.java.net/panama/ for versions aligned the shipped JDK 17/18/19. This means a developer could try samples for the JDK version they already have installed without needing to build either JDK or jextract themselves. Hopefully it only needs posting every 6 months.

Enum as an include option
by Nir Lisker 18 Oct '22

18 Oct '22

Hi, It looks like there is no --include- option for enum, although Declaration.Scoped.Kind.ENUM exists. Is it part of the WIP or is there another reason it's not an option? - Nir
