In #9798, we added a check to map `ENOBUFS` to `WOUDLBLOCK` on MacOS. More experimentation on that front revealed that this was actually incorrect and the UDP sending task will hang as the OS does **not** notify us once there are new buffers available. This may explain some random connection hangs that some users have recently complained about. I've already disabled the feature flag in production, this PR therefore only removes code that is now inactive. In order to make this as robust as possible, we implement a retry loop with an exponential backoff, starting a 2ns. At most, we will be retrying such a packet for 16ms. Local experiments on my Macbook have shown that most of the time, new buffer space is available within 1ms. The exponential backoff ensures we retry very quickly on faster machines but still successfully send the packet on slower machines. According to the linked mailing list, the link-speed of the attached network has nothing to do with this which makes sense. UDP has no congestion control so sending packets is merely a function of how fast the CPU can process them.

This is a Next.js project bootstrapped with
create-next-app.
Getting Started
First, install dependencies and populate the timestamps.json file:
pnpm setup
Next, create files .env.local and .env.development.local in this directory.
Put this in .env.local:
NEXT_PUBLIC_MIXPANEL_TOKEN=""
NEXT_PUBLIC_GOOGLE_ANALYTICS_ID=""
NEXT_PUBLIC_LINKEDIN_PARTNER_ID=""
FIREZONE_DEPLOYED_SHA=""
And this in .env.development.local:
# Created by Vercel CLI
EDGE_CONFIG=""
FIREZONE_DEPLOYED_SHA=""
SITE_URL=""
VERCEL_DEEP_CLONE=""
After that, make sure to contact the team for their values.
Then, run the development server:
npm run dev
# or
yarn dev
# or
pnpm dev
Open http://localhost:3000 with your browser to see the result.
You can start editing the page by modifying app/page.tsx. The page
auto-updates as you edit the file.
Linting
This project uses Prettier to format code and ensure a consistent style. Use the .prettierrc.json in the root of this repo to configure your editor.
