thanks , will check for updates

Kevin•3/26/24, 3:53 PM

Nah, Workers directly, so I’d assume wrangler/miniflare?

captain•3/26/24, 11:53 PM

everybody else seeing logs down in dashboard and via wrangler?

captain•3/26/24, 11:53 PM

seeing one other person posted the error in github, cloudflare devs aware?

James•3/26/24, 11:57 PM

Yeah this tied to the same incident: https://www.cloudflarestatus.com/incidents/b31dxdz60366

Cloudflare Dashboard and Cloudflare API service issues

James•3/26/24, 11:57 PM

Once that's resolved, let us know if you're still having issues

Old Man Maker•3/27/24, 5:43 AM

Some feedaback for the dashboard team - the KV search prefix that does not search the entire namespace is next to useless for large collections of keys. Perhaps an option to only search on the current paginated collection, or to search the entire namespace?

Old Man Maker•3/27/24, 11:45 AM

BTW - this 'Log size limit exceeded: More than 128KB of data (across console.log.....' is entirely unhelpful

I need like a tiny vm purely to hold database backups and logs. Could workers with for example a debian image be a good fit for that?

Chaika•3/27/24, 2:48 PM

Workers run using the Javascript Engine v8, Same as Chrome, using isolates/shared runtime separate environment. They can't run images or other operating systems, etc. Most you can do is WASM, and they have no storage outside of using something external like r2/etc

Tangenius•3/27/24, 2:48 PM

Okay, thanks for the clear explanation

Chaika•3/27/24, 2:49 PM

Sure. There's a nice doc here as well:https://developers.cloudflare.com/workers/reference/how-workers-works/

Is there any way to target a specific geographic location when executing a worker?

Hello, I’m Allie!•3/27/24, 8:47 PM

There is Smart Placement too

Hello, I’m Allie!•3/27/24, 8:48 PM

Though you don't really "pick" that

Hello, I’m Allie!•3/27/24, 8:48 PM

Other than where your origin is

HHello, I’m Allie!Though you don't really "pick" that

Chaika•3/27/24, 8:49 PM

you can kind of hack it by binding it to a d1 and it'll run near the d1 but not perfect

jason•3/27/24, 8:51 PM

I'm writing a worker to measure a website's performance, and I'd like to be able to measure it from multiple spots around the world. Right now I'm proxying requests through some Amazon API Gateways to get the "source" of the request in different parts of the world. But I'd like to be able to only use CF and not have to rely on proxy servers.

jason•3/27/24, 8:55 PM

It looks like attaching to a D1 might be the best choice at the moment.

Chaika•3/27/24, 8:56 PM

for my own monitoring I just have cron going to DOs with location hints in each region

Chaika•3/27/24, 8:56 PM

a bit expensive though since you pay for duration with DOs

Chaika•3/27/24, 8:57 PM

with the d1 hack or DOs, you can only go where DOs go eitherway, which means no South Africa, or South America, or Sydney Australia, China, Russia, etc

Chaika•3/27/24, 8:57 PM

only where DOs run: https://where.durableobjects.live/, and only in coarse region assignments

jason•3/27/24, 8:57 PM

Okay, so probably just sticking with my proxy servers then.

You pass it in, or use

AsyncLocalStorage

Hello, I’m Allie!•3/28/24, 9:40 AM

Yeah, so like

   // use env here
}

export default {
  async fetch(req, env) {
    myNewFunction(env);
    // Do more stuff
  }
}

   // use env here
}

}

Hali•3/28/24, 9:44 AM

ah, I see. So now we can use env.variable_nameenv.variable_name, right?

HHali ah, I see. So now we can use `env.variable_name`, right?

Hello, I’m Allie!•3/28/24, 9:44 AM

Yup

Hali•3/28/24, 9:45 AM

Gotcha, I'll give it a try. Thank you so much!

HHello, I’m Allie!Yup

Hali•3/28/24, 9:53 AM

Sorry, could you mind showing me how to use AsyncLocalStorage as I feel like this would be more convenient? I have some variables stored in cloudflare variables. How could I get them? Thank you!

ItsWendell•3/28/24, 10:25 AM

I think the part where you assign domain names to a worker has disappeared from the Cloudflare Dashboard, should be at: https://dash.cloudflare.com/XXXX/workers/services/view/WORKERNAME/production/triggers right? But it's gone? Any tips on how to bind (sub)-domains to workers now?

@Chaika have you had issues with query encoding on Backblaze B2 before?

Ddave @Chaika have you had issues with query encoding on Backblaze B2 before?

dave•3/28/24, 2:27 PM

I can't use

in the response-cache-controlresponse-cache-control query parameter on Backblaze B2. It works fine on R2 though. I'm using aws4fetch for signing.

dave•3/28/24, 2:30 PM

oh, manually replacing

with %3D%3D on the signed URL works

dave•3/28/24, 2:30 PM

weird.
