golang runtime

[Alexander Tormasov]

Good, I start yesterday moving everything into world repos.
Except anon_mapping for mmap which obviously will be in libc near file_operations.cc

Question to Nfeske@ / other developers: where should I put context switches family (mcontext.h myacontext.s - asm for x86_64 and general mcontext.cc )- to the same libc?

Or I need to keep them in repos/world - while this is not a separate library/feature?

To what sample code I can take look as example ?

I have modified your example: just added some networking to your go app. I have attached the file to the letter.


Oh, I think, I haven't mentioned it before. To enable the networking in the QEMU you need to add the following line to the run script:
```
append_qemu_nic_args
```

For me, localhost still wasn't available, so I was connecting to a remote host.

Thank you! I will try to return to this topic.
By the way, what test you do use for debugging?
Just to try to understand configs/etc - my genode network experience is a bit limited...

Sincerely,
Alexander

Hello all

We have invested some time analyzing golang and how much it will take to make it production-ready.

The build system requires some effort, and it's not fully clear if it's a one-time effort. Different golang projects use other build systems (bazel and so on).

Networking is crucial for us, and we invested most of our time making it work. Unfortunately, we failed to do so: it seems the goroutines scheduler makes some assumptions that we overlooked. So, at the end of the day, we have a network that sometimes works.

I have proposed a patch [1] that will fix some issues and hopefully help someone later on.

Unfortunately, we will not invest more resources in porting golang since it seems too resource-consuming for our small team.
