Conan: [feature] push (simulated via polling?) of config updates

[michaelmaguire]

It is frequently a problem in our corporate environment that conan config settings change, for example recently our internal Artifactory admins changed the URLs we should use to find our internal repos.

Our team of 50 developers all used:

conan config install git@<internalrepo>/conan_common_config_install.git --type git

To get their settings.

It would be very helpful if conan would remember the last conan config install location, and from time to time (e.g. every 20th interactive conan invocation) check the previous location for updates, and log a suggestion e.g. at log level WARN.

WARNING: Config changes noted, run `conan config install git@<internalrepo>/conan_common_config_install.git --type git` to refresh.

• [x] I've read the CONTRIBUTING guide.

Hi @michaelmaguire

Both are already available features:

• Conan memorize the previous conan config install commands, so calling conan config install without arguments will call in order the list of previous installs.

• There is a new conan config install auto-update feature, that will call this command (without arguments) periodically. Given that the configuration for this feature is also in conan.conf, the first conan config install with args can also schedule a given interval for auto-updates. Check https://docs.conan.io/en/latest/reference/config_files/conan.conf.html (config_install_interval)

Wow, that's psychic levels of service! Awesome. Thanks.

And today 1.27 release will include conan.conf configuration to validate also the current running Conan client version, so it is possible to force developers to update their clients :)

I think I just ran into a bug with this.

I've raised it as: https://github.com/conan-io/conan/issues/7297 "[bug] Automated config update exception needed for conan config install commands to prevent catch-22"
