Version 0.16.1

[tomchristie]

0.16.1 (October 8th, 2020)

Fixed

• Support literal IPv6 addresses in URLs. (Pull Correctly handle ipv6 addresses as a part of URL #1349)
• Force lowercase headers in ASGI scope dictionaries. (Pull Force lowercase ASGI headers #1351)

appying the httpx version =>0.16.1 here 1.0.5 still not correct the occuring :
"raise to_exc(exc) from None
httpcore.ConnectError: [Errno -2] Name or service not known"

what's going wrong?

[tomchristie]

@bdieng-sudo Couldn't really say from that alone. I'd suggest start a discussion, and include a bit more information about what you're actually doing. Someone will probably be able to help you out a bit if you do that.

Hi Tom,
thanks for your feedback.
Thus I'm tryinh to générate a shaman application with as an argument : a yaml file.
the error occurs at this stage as shown below:

shaman-install configuration.yaml

I'd suggest start a discussion, and include a bit more information about what you're actually doing.

I'd suggest using the "discussions" feature in the future...

httpx.ConnectError: [Errno -2] Name or service not known

Most likely you're attempting to make a request to an invalid URL.

This... http://api:5000 looks wrong to me.

[bdieng-sudo]

that's the question.
the API:5000 is defined s a container as shown in the "podman ps -a" cmd
(env) hana03:/shaman-next # podman ps -a

[bdieng-sudo]

this join your diagnostic Tom.
when simply run "curl http://api:5000"
........
........

The requested URL could not be retrieved

---

The following error was encountered while trying to retrieve the URL: http://api:5000/

Unable to determine IP address from host name api

The DNS server returned:

Name Error: The domain name does not exist.

This means that the cache was not able to resolve the hostname presented in the URL. Check if the address is correct.

[tomchristie]

I don't know anything about podman, so you probably need to ask there instead. But you likely want to be connecting to http://127.0.0.1:5000, rather than http://api:5000/.

I can't really help you out anymore with this, since it's not an httpx issue.

Although we could do with a better error message for this case, making it more clear that the hostname "app" didn't resolve.

[bdieng-sudo]

Hi Tom,
thank U for your support. I have to check why the localhost IP has been substitute by API....
in SLES7, podman has some properties natiev to SUse i need to better understading i guest.
regards!
