vdirsyncer 0.19: digest auth broken

[0-wiz-0]

When I updated from 0.18 to 0.19, 'vdirsyncer sync' broke.

Syncing remote1/default

In case it matters, this is with Python 3.11.0 on NetBSD, aiohttp 3.8.3, server is running baikal 0.9.2

The config for the server looks like this:

type = "caldav"
url = "https://caldav.hostname.at/cal.php/principals/wiz/"
username = "wiz"
password = "something"
auth = "digest"

Removing auth or setting it to basic doesn't work.

Just acknowledging that I saw this issue last week. This is indeed broken, I'll try to address it soon.

[WhyNotHugo]

Relevant: aio-libs/aiohttp#4939

[WhyNotHugo]

Probably gonna have to copy chunks from aio-libs/aiohttp#2213

[WhyNotHugo]

Pinning this issue since it's high priority to get this through.

I have the same issue on a http remote:

[storage example_remote]
type = "http"
url = "https://mail.example.com/home/user@example.com/Calendar.ics"
auth = "guess"
username = "user"
password = "hunter2"
read_only = "true"

results in:

error: Unknown error occurred for example: BasicAuth() tuple is required instead

A lot of the networking bits were re-written (in great part due to some dependencies being unmaintained themselves and not working on recent python versions).

During this rewrite, I omitted Digest Auth. It needs to be implemented (and I'll get around to it as soon as I get a chance), but there's no workaround in the meantime.

[hnrd]

digest was a good keyword for me, it works when I change auth to basic (remote is a Zimbra server) 👍

It seems this bug prevents me from using vdirsyncer, too with baikal.
Baikal doesn't support basic-auth and digest seems to be broken with vdirsyncer. Is there any workaround?

Just want to say that Baikal does support basic authentication (at least v0.9.3). The method can be set in the admin web interface under system settings. It works with vdirsyncer for me.

@clombt ah thanks, I haven't seen this. Thanks for the pointer!

Hi @WhyNotHugo
do you have an update on this?
I'm using vdirsyncer version 0.19.2_2 from my distribution and I'm facing the same issue.
