Package pwru for major distros about pwru HOT 17 OPEN

Sorry for the delay. I've been busy with other Arch projects and haven't had time to package new things into the repositories for a couple of months.

I've uploaded cilium-cli and pwru to the Arch repos today. Debug packages are also available from https://debuginfod.archlinux.org as well.

https://archlinux.org/packages/community/x86_64/pwru/
https://archlinux.org/packages/community/x86_64/cilium-cli/

Package files can be found here.

I can help for Fedora

from pwru.

I would like to work on this.
Any advice on how to begin?
Thanks

Let me ping some maintainers first. Mind pinging me (martynas) on Slack? We can coordinate there.

from pwru.

sure!

from pwru.

Hey @brb Is this still up for grabs? Let me know if I can try tacking this

from pwru.

Yep, just that I still didn't manage to coordinate all efforts with pkg maintainers. Which distro would you target first?

from pwru.

I use Arch Linux so I would prefer that as a good starting point.

Also, if possible, can you share some articles/docs I can refer to with respect to packaging such an app

from pwru.

Great! I'm not familiar with distro packaging. Perhaphs you could reach out to the Arch community? @Foxboron mentioned that he might help with Arch.

@Foxboron Thanks a lot!

@ShubhamPalriwala Maybe let's continue with Debian/Ubuntu?

from pwru.

bfp2go looks at /sys/devices/system/cpu/possible on the building machine to determine the number of cores to add hooks for, and pwru seems to fail if the number does not match what is observed at runtime. This makes it pretty difficult to build any distribution packages, even for internal corporate distribution.

from pwru.

@terinjokes Do you have an output of such a failure?

from pwru.

@tao12345666333 Great! Will you ping Fedora pkg maintainers?

from pwru.

yes.

from pwru.

@brb If the machine that compiled pwru has more CPUs than the machine that runs it I get the following error, along with an exit code 1:

Creating perf event reader: failed to create perf ring for CPU 1: can't create perf event: Invalid argument

If the machine that compiled pwru has less CPUs than the target machine (eg, was built in a CI environment) it runs without any error messages, but I don't see packets scheduled onto the higher CPU cores.

I can create a separate issue, but seems like the current implementation will have issues with distribution packages.

from pwru.

@terinjokes Could you create a separate issue, and include strace output? Thanks. My colleague said that the CPU detection should happen during the runtime.
