v2 breaks support for configuration lists on environment variables #48
Comments
Thank you for the bug report! I tried to do as much testing as I could in #26 but inevitably some bugs may slip through, the goal of v2 was to be fully backwards compatible so I'll look to push a fix ASAP. I've just added some extra tests in 72fc88a and everything seems to work as expected. Please could you provide an example config and let me know the behavior before/after, I'll look into it right away! |
No problem. The config I was using which I saw the bug on had the following environment variables set (viewed from docker inspect, this is all of them except PATH, names changed too)
If it helps, the domain I was trying to authenticate with was the middle one of the 3. |
Oops didn't answer the rest of your questions. |
Brilliant, I think I found the bug, I had incorrectly thought the v0 config option was called I have fixed CSV support for |
*I've pushed the fix in 3e92400 Thank you for your bug report and sorry for causing you an issue whilst you were away! |
Thank you for the very quick fix and this simple tool. :) |
I've used environment variables exclusively for configuration rather than files.
This included multiple domains in the DOMAIN environment variable.
The recent push of v2 to the latest tag on docker hub broke my auth (as I had watchtower updating for me) with a log message:
time="2019-06-11T00:40:13Z" level=error msg="Invalid email" email=<redacted valid email> source_ip=<redacted IP>
I think this is because auth.go:ValidateEmail fails as config.Domains has treated multiple domains in a comma separated list as a single domain, so the domain supplied doesn't match. Looking at changes to config.go I wasn't able to see where this change came from - it looks like config.go is new for v2. I'm away from my developer pc so not able to dig further easily.
This change from comma separate lists to repeating single values could impact any setting which had multiple values set via environment variables - as duplicate environment variables aren't possible.
There is no deprecation warning logged on startup for this change of behaviour (I wasn't using DOMAINS as the environment variable which would show this). Maybe I had screwed up my config and been lucky it was working.
I'll need to update my config to an ini file which I didn't notice/realize was an option before, that looks better suited for how I've configured as .
Thanks for your time.
