Cannot connect to CodeChecker server from command line

[mheiskan]

Hi,

I installed the latest version from SnapStore. The server starts fine with

codechecker server --not-host-only --workspace .codechecker

and responds to a browser. I did not enable any authentication methods. However, only the server related command lines seem to work:

> codechecker server -l
Your running CodeChecker servers:
---------------------------------------
Workspace                   | View port
---------------------------------------
/home/mheiskan/.codechecker | 8001     
---------------------------------------

Storing results does not work, nor listing information from the server:

I've tried enabling method_dictionary authentication, but the command line still reports I should check the server is running. Any hints on how to fix the problem?

The problem is due to the environment variables, unsetting them works:

❯ http_proxy="" https_proxy="" codechecker cmd runs
[INFO 2021-06-03 18:48] - Checking local passwords or tokens in /home/users/mheiskan/.codechecker.passwords.json
[INFO 2021-06-03 18:48] - No saved tokens.

-------------------------------------------------------------------------------------------------------------------------------------
Name | Number of unresolved reports | Analyzer statistics | Storage date | Version tag | Duration | Description | CodeChecker version
-------------------------------------------------------------------------------------------------------------------------------------

This also works:

❯ no_proxy=".mydomain.com,localhost" codechecker cmd runs

@mheiskan I think you are using the 6.15.2 release. I already created a ticket which will handle invalid proxy settings (#3198) but this is not available in the 6.15.2 release. So with my patch at least you will get a proper warning message when these variables contains invalid settings.
