The worst is "hey they are running proprietary fork and not open source anymore" when the code is available in plain sight. Canary build is available with one command. The stupid article made a huge stink about it without this key fact. Now they added the update but damage is done.
If you would like to join us in this thread now that this misunderstanding has been corrected, please, share your thoughts on the Bun community, what the "Bun community" even is, and how it has been impacted by a sudden, unannounced rewrite.
Bun "user community", is not affected by this at all (yet) except the ai doomers/zig fanatics.
When v1.4.0 is fully released, and if Bun team can't get it to full feature (and no new serious bugs) parity with last zig version within a few versions (let's say v1.4.2), then there will be real effects.
I will be testing v140 after release. As a bun user community member, I expect no new type of crash, slightly faster perf/less memory usage and move on with my life.
A rewrite like this is unprecedented but doesn't mean impossible. I am cautiously optimistic.
This is, as you say, unprecedented. Not impossible, cautious optimism is a fine response. But to bring back a point I made earlier in the new old light: Then let's be cautious. Let's do some announcements ahead of time. Let's get some people in and get some physical hands on the codebase. Let's not go from "Stop freaking out, it's just an experiment!" to a silent merge to main in a week. That causes reduced trust in the project from those even just a hair less optimistic than you, and that's clearly unhealthy for the project no matter how you define "the community."
Jarred earned the trust by providing value. People who say trust is reduced without actually seeing the result, never had trust to begin with.
It's not like they merged and dumped it on to the world immediately. It's available as canary. They are doing their own dog fooding. Prisma is using the canary successfully.
As long as oven team can deliver a zig version equivalent stable bun, it is a success in my book. After that they can focus on resolving as many unsafe as possible and then the real benefits will materialize.
