Hi, I have a little problem but I think it's a bug so I'd rather share it. In a dev environment, with one worker communicating with another using RPC, and with an environment variable configuration for dev and prod like this :

[env.dev.vars]
API_HOST = "localhost"
API_PORT = "9000"
[env.production.vars]
API_HOST = "engine.corsa.club"
API_PORT = "443"

[env.dev.vars]
API_HOST = "localhost"
API_PORT = "9000"
[env.production.vars]
API_HOST = "engine.corsa.club"
API_PORT = "443"

[env.dev.vars]
API_HOST = "localhost"
API_PORT = "9000"
[env.production.vars]
API_HOST = "engine.corsa.club"
API_PORT = "443"

[env.dev.vars]
API_HOST = "localhost"
API_PORT = "9000"
[env.production.vars]
API_HOST = "engine.corsa.club"
API_PORT = "443"

My Worker A calling Worker B can't find a worker with the name I assigned to Worker B.
Command that works:
npx wrangler dev -c authentification/wrangler.toml --port 9002
Command that doesn't work:
npx wrangler dev -c authentification/wrangler.toml --env dev --port 9002

By adding the "env" property, it no longer finds the Worker

Environments change the name of the Worker

kian•4/19/24, 2:45 PM

If you have name = "foo"name = "foo" and don't specify a name specifically under env.devenv.dev, then that Worker when ran with --env dev--env dev is now called foo-devfoo-dev.

Is it possible to have a scheduled worker call to a HTTP worker via a binding? All the examples I see mention passing on the request.urlrequest.url when calling fetch()fetch(), which wouldn't exist within the context of a scheduled worker?

Lambo•4/19/24, 8:48 PM

Ah okay, thanks!

luna•4/20/24, 12:18 AM

is there an expected delay from a request happening to it showing up on the metrics page?

luna•4/20/24, 1:09 AM

do tail workers only work for fetch requests?

kian•4/20/24, 1:25 AM

Should work for everything - it's the same stuff that powers wrangler tailwrangler tail

luna•4/20/24, 1:31 AM

hmm.

luna•4/20/24, 1:43 AM

do i maybe have it setup wrong?

i have this in my wrangler.toml with the main file exporting fetch, scheduled and queue handlers.

[[queues.producers]]
queue = "stats"
binding = "QUEUE"

[[queues.consumers]]
queue = "stats"
max_batch_size = 10
max_batch_timeout = 30

does CF have some product which allows pubsub for clients? i only need sub so i thought of polling and websockets, but was wondering if cf has something better for scale

zegevlier•4/20/24, 9:48 AM

Not an employee, but the startup time you're referring to is the startup limit. As in, your worker needs to be able to start up within that time for it to run at all.

A Worker must be able to be parsed and execute its global scope (top-level code outside of any handlers) within 400 ms. Worker size can impact startup because there is more code to parse and evaluate. Avoiding expensive code in the global scope can keep startup efficient as well.

zegevlier•4/20/24, 9:49 AM

Are you seeing slow cold starts? What promted this question?

zegevlier•4/20/24, 9:53 AM

As far as I know that's still the case. And you're right that a larger script results in a longer cold-start time, so if you require fast starts make sure to keep your worker small.

dumb question but how do I just build the minified worker.js with

Is there a known issue around the cloudflare/wrangler-action@v3cloudflare/wrangler-action@v3 sometimes failing to deploy due to binding to D1 failing (error 10021)? I can simply re-run my Action and it then succeeds, so it seems to be a bug. I can raise an issue if required
