Allow users specify the user-specific config via an environmental variable

Ability to specify location of the user mock.cfg with an environmental variable

I would like to be able to specify an additional location for the user-based mock.cfg file based on an environmental variable. Currently these locations are:

1. .mock/user.cfg
2. .config/mock.cfg

The reason is that I have tens of projects with different customizations and unless it's done it's difficult to manage.

While mock -r foo searches for the files you mentioned, you can still use mock -r some/path/foo.cfg and mock will use this full path.
When the parameter has suffix .cfg it is interpreted as a path.
Is this sufficient for you?

So I have the main configuration files (e.g. centos7) under /etc/mock and mock is already called with something like -r /etc/mock/centos7.

Now, if I want to tweak something without changing that system wide config, I could override a config opt by putting my them into ~/.config/mock.cfg, right? But that's not great for my case because each of my builds may require a different override and I would have to change ~/.config/mock.cfg for each custom build, no?

If the above is how it works, then I would like to instruct mock to look into an additional place for the overrides - via an environment variable perhaps.

Let me know if this makes sense or not

Here's what I'm proposing:

diff --git a/mock/py/mockbuild/config.py b/mock/py/mockbuild/config.py

I understand what you are trying to achieve. But I think this add unnecessary complexity to Mock.

You can achieve the same by

$ cat ~/my/configs/for/tests/one.cfg
include('/etc/mock/centos+epel-7-x86_64.cfg')
#your specific overrides
config_opts['foo1'] = 'bar1'

$ cat ~/my/configs/for/tests/two.cfg
include('/etc/mock/centos+epel-7-x86_64.cfg')
#your specific overrides
config_opts['foo2'] = 'bar2'

$ WHAT=one
$ mock -r  ~/my/configs/for/tests/${WHAT}.cfg  some.src.rpm

or

$ cat ~/testdir1/centos7.cfg
include('/etc/mock/centos+epel-7-x86_64.cfg')
#your specific overrides
config_opts['foo1'] = 'bar1'

$ cat ~/testdir2/centos7.cfg
include('/etc/mock/centos+epel-7-x86_64.cfg')
#your specific overrides
config_opts['foo2'] = 'bar2'

$ WHAT=testdir2
$ mock -r  ~/${WHAT}/centos7.cfg  some.src.rpm

The last one does exactly what you are trying to achieve. Right?

Or, can you use something like this wrapper?

$ cat ~/bin/mymock 
#! /bin/sh
test -n "$MOCK_CFG_PATH" && exec mock -r "$MOCK_CFG_PATH" "$@"
exec mock "$@"

Ah yeah this could work indeed. The problem include directive is crucial here. I can go with this and post here in case there’s some unexpected complication. Thank you!!

i am closing this for now.
