204 no content

kianOP•10/27/22, 10:34 PM

Yeah, if you pass a body when one isn't expected then you'll get an internal error.

kianOP•10/27/22, 10:34 PM

I'd say it annoys me but S3 infinitely hangs if you do it, so I guess R2 behaves better.

albert•10/27/22, 10:36 PM

nothing happens when i send it without a body, returns 204 no content and it doesnt delete anything

kianOP•10/27/22, 10:38 PM

If you do

GET

GET

to the same endpoint, what do you get?

Wondering how to add CORS support to your R2 buckets? We'll go over how to format a CORSRule and allow presigned PutObject requests.

I'm sure I've missed that here somewhere, but: Are there any plans to restrict api tokens to specific buckets in the near future?

kev-ac•10/28/22, 12:36 PM

Just knowing that all data of all buckets is in danger if one app has a vuln which may leak a keyset is a bit worrying.

Yep! This is pretty high on our list

500 error usually means that either your request is malformed that R2 can't respond correctly or some bug, etc.

kev-ac•10/28/22, 2:11 PM

R2's model is strong consistency so any mutating action (POST, PUT) is reflected immediately (except deleting a bucket) and there is no replication lag across regions (as data is stored in one region)

kianOP•10/28/22, 2:27 PM

There is no replication currently - your bucket's data is kept in one location.

kianOP•10/28/22, 2:27 PM

The 500 sounds like an issue with R2 more than anything else

kev-ac•10/28/22, 2:27 PM

The moment R2 responds with a "successful" response code (20x) the mutating action is done. Any GET after POST / PUT are immediately available (independent of size)

kev-ac•10/28/22, 2:29 PM

One exception will be Multipart uploads. There the change happens when you complete the multipart upload.

kev-ac•10/28/22, 2:31 PM

With S3 there is one edge case where GET requests can respond with the old or new value when upload is done but has not yet been acknowledged to the client. But I don't know how R2 handles this as it's so unlikely to encounter.

JustinNoel•10/28/22, 4:52 PM

It doesn't look like there's a way to detect if an object exists using a Worker.

For example, I'd like to do something like this just to see if an object exists or not.

await env.MY_BUCKET.list("my_key")await env.MY_BUCKET.list("my_key")

Right now, it seems the only way to do that is

await env.MY_BUCKET.get("my_key")await env.MY_BUCKET.get("my_key")

This seems wasteful as I don't actually need the object's data or want to wait around for a 10MB file to be sent across the wire. I just want to know if it exists.

Is there any way to do this?

Sid•10/28/22, 5:01 PM

Yep, have you considered a .head().head()? That will not respond with your object's body. Even for .get().get()s, you get back a stream with your object's body that you should be able to discard, you shouldn't need to buffer the entire body in memory.

CCorin Ah came here to ask, getting the same thing here

Sid•10/28/22, 5:02 PM

Yeah this is being investigated!
