error: Evaluation aborted on #<TYPE-ERROR expected-type: SINGLE-FLOAT datum: 1.1d0>. about dexador

[fukamachi]

What's the value of *READ-DEFAULT-FLOAT-FORMAT* in your environment?

[shixiongfei]

CL-USER> READ-DEFAULT-FLOAT-FORMAT
SINGLE-FLOAT

[fukamachi]

I suppose that you loaded & compiled dexador with setting *READ-DEFAULT-FLOAT-FORMAT* 'double-float.

Can you try (dex:get "http://lisp.org" :version 1.1s0) ?

[shixiongfei]

(dex:get "http://lisp.org" :version 1.1s0)

1.1 fell through ECASE expression. Wanted one of (1.1d0 1.0d0).

[shixiongfei]

I set *READ-DEFAULT-FLOAT-FORMAT* to double-float and reloaded dexador, but I got the same error.

[fukamachi]

Did you delete fasl caches before reloading?

[shixiongfei]

Yes, I deleted the cache and got the same error.

[fukamachi]

Then, that may not because of the setting of *read-default-float-format*, which I could reproduce.

[shixiongfei]

Em, what shall I do next?

[jnc-nj]

Can confirm this occurs in dockerized container running ubuntu 16.04.

This is a bad temporary workaround, but see jnc-nj/dexador@a81de22

@fukamachi
This is probably incorrect, but the problem I see is if dexador isn't compiled properly, backend/usocket.lisp declares version to be type single-float, which will raise an error when you manually set *read-default-float-format* and give :version 1.1d0

[shixiongfei]

@jnc-nj Glad to see that the problem is moving forward, thanks a lot.
