Ahh - interesting. What is the output of zef --help ?

[melezhik]

it's on my second comment

[tony-o]

@melezhik zef, not fez - where does zef think its config is?

[melezhik]

ah ... )))

Ah - definitely a permissions issue. I think I'm holding up merging a fix for this that @patrickbkr has put together. I'll review/get the fix out tomorrow.

[patrickbkr]

@tony-o The PR I created fixes permission errors when writing the fez config (adding username and token). It doesn't address changing the zef config. The zef documentation has a paragraph on how the right config file is chosen including how it locates the user config file. From what I read in those docs:

• The quick and dirty solution is to just write to $*HOME/.zef/config.json
• The clean solution is to scan zef --help for the config path, open that, extact the RootDir option and write to the file $RootDir/config.json.

[tony-o]

gotcha. the way i'm doing it now is likely right. it just uses zef's method of %*ENV // guess-config-path. I've added a check for write permissions @melezhik - will push the fix today.

[tony-o]

@melezhik #10 should give you a better error message, it can't fix the problem though. the actual problem being that the user you're running fez as doesn't have w permissions to the zef config file -

[melezhik]

the error message is better now:

[tony-o]

@melezhik you able to work with that? the way zef is set up is unlike what @patrickbkr did with fez's where they cascade, with zef it's all or nothing -

[melezhik]

I mean I just inform what I get on my env. Do you think it's a fez's bug or it's just a very specific zef configuration that I have on my server and we could just ignore it?

[patrickbkr]

I just created an issue for zef to provide a way to change / add a single configuration value as that indeed seems to not be implemented.

[tony-o]

That may end up getting denied. Either way nick is interested in merging the zef p6c stuff so he doesn't have to manage that trash anymore and then this should become a moot issue

[tony-o]

Going to close this as a file permissions issue and not actually an issue with fez unless you object (please reopen if you do)
