@Walshy It looks like a cron job failed to run today on one of my workers - I got no notification about it or anything

I doubt the 100MB (and greater) request size limit applies to AI workers- -> https://developers.cloudflare.com/workers/platform/limits/#request-limits

And yeah there's no limit so

F

fry69•10/30/24, 10:19 AM

If the raw image size is 3,5mb this might blow up ~30% with base64 encoding, some AI APIs I know have a 4MB hard limit for image size (in base64).

fry69•10/30/24, 10:19 AM

Dunno if this applies to Cloudflare AI though.

Martijn•10/30/24, 10:20 AM

Hmmm, is there a way to easily compress the image in a worker?

Cloudflare has a separate service for this -> https://developers.cloudflare.com/images/

M

Martijn•10/30/24, 10:21 AM

Yeah, not really what's needed here I think. I want to use AI to classify some images but might not work if there's such a small limit

F

fry69•10/30/24, 10:21 AM

You can of course do this manually inside the worker, but you have to code this yourself (you'll kind of pay for the conversion in both ways, either via the image service or via CPU milliseconds for your worker).

Git heavily relies on a working filesystem (as git effectively uses the filesystem as its database), I don't know if a VFS shim around R2/S3 will ever make git happy. It may be easier to write/modify a git implementation to use R2/S3 operations directly and skip the VFS layer (like Microsoft did with ditching VFSForGit and moving everything in their git fork)

DiamondDragon•10/30/24, 2:54 PM

Quick maybe dumb question. Can you define a worker entry point in a worker and access and call the class and it’s methods in the same worker? I understand with RPC you can export the class in the same file as the module default export and it can be used in other workers. But wondering if it can be used in the source worker and other workers

Hey

I am trying to call a DO from Worker B when DO is exported from worker A.
Worker A looks like this:

# wrangler.toml B
name = "worker-B"
# ...
[env.dev.durable_objects]
bindings = [
  { name = "DO", class_name = "Do", script_name="worker-A" }
]

# wrangler.toml B
name = "worker-B"
# ...
[env.dev.durable_objects]
bindings = [
  { name = "DO", class_name = "Do", script_name="worker-A" }
]

# wrangler.toml B
name = "worker-B"
# ...
[env.dev.durable_objects]
bindings = [
  { name = "DO", class_name = "Do", script_name="worker-A" }
]

# wrangler.toml B
name = "worker-B"
# ...
[env.dev.durable_objects]
bindings = [
  { name = "DO", class_name = "Do", script_name="worker-A" }
]

# wrangler.toml A
name = "worker-A"
# ...
[env.dev.durable_objects]
bindings = [
  { name = "DO", class_name = "Do" }
]

[[migrations]]
tag = "v1"
new_sqlite_classes = ["Do"]

# wrangler.toml A
name = "worker-A"
# ...
[env.dev.durable_objects]
bindings = [
  { name = "DO", class_name = "Do" }
]

[[migrations]]
tag = "v1"
new_sqlite_classes = ["Do"]

# wrangler.toml A
name = "worker-A"
# ...
[env.dev.durable_objects]
bindings = [
  { name = "DO", class_name = "Do" }
]

[[migrations]]
tag = "v1"
new_sqlite_classes = ["Do"]

# wrangler.toml A
name = "worker-A"
# ...
[env.dev.durable_objects]
bindings = [
  { name = "DO", class_name = "Do" }
]

[[migrations]]
tag = "v1"
new_sqlite_classes = ["Do"]

And the index.ts in worker B is a fetch calling a DO stub (with RPC), and exporting the fetch.
On Worker A, it's a simple fetch + DO sqlite, both exported.

Worker A deploys fine and works fine with DO. I get this error on deploy for worker B (that should use the DO from worker A):

Cannot create binding for class in script 'worker-A' that does not exist [code: 10061]

Cannot create binding for class in script 'worker-A' that does not exist [code: 10061]

Any idea what I could be doing wrong?

my plan is when someone clicks something from my CF pages site, it creates a D1 database and we need to bind that to 3 CF workers. It doesn't have to be instant but quick enough that it's not waiting 5 - 10 minutes
