Hi,
Here is a list of things, not necessarily in any importance order, I am
proposing we try to accomplish for next releases:
- Prune the list of issues
- Close anything that is irrelevant or possibly completed
- One subcategory I can think of, are issues about improving java
wrapper like this one -
https://github.com/cloudius-systems/osv/issues/169. Given we can
run unmodified /usr/bin/java without need of a wrapper and given the
wrapper (java.so) does not support (or is even compatible) with many
features of Java 9 and higher, I suggest we close any issues like 169
which
are about improving java.so - I do not think it is worth any time
investment (the only real benefit of java.so is ballooning feature
which is
broken - https://github.com/cloudius-systems/osv/issues/796 and
https://github.com/cloudius-systems/osv/issues/1038 [duplicate of
796?] - but if anyone is interested in fixing it I think we might
support
it without java.so anyway).
- Better annotate existing issues and especially select ones as
'"good first issue" (see
https://github.blog/2020-01-22-browse-good-first-issues-to-start-contributing-to-open-source/
)
- Better support Linux executables built for Musl-based distributions
like Alpine (see https://wiki.musl-libc.org/projects-using-musl.html)
- These may work even better given OSv libc implementation is to
great extent based on musl
- Tooling
-
- Improve capstan
-
- Better support QEMU on OSX (new accelerators)
- Support pulling artifacts from GitHub nightly releases repo
- Support running Firecracker, QEMU microvm
- Support Virtio-FS
- Create plugins to deploy Java, Node, etc apps
-
- IntelliJ
- Gradle
- Maven
- Run Docker images (possibly musl-based like Alpine are better)
- There is already existing example -
https://github.com/cloudius-systems/osv-apps/tree/master/openjdk12-jre-from-docker

consumption
