Update agent to version 6f29190

[tombruijn]

Rename APPSIGNAL_ENVIRONMENT to public env version

Rename the internal APPSIGNAL_ENVIRONMENT env var to the publicly known
APPSIGNAL_APP_ENV env var.

This makes all the agent config options consistent with each other.

[skip changeset] because it requires an agent update that will include
a changeset.

Update agent to version 6f29190

• Log revision config in boot debug log.
• Update internal agent CLI start command.
• Rename internal _APPSIGNAL_ENVIRONMENT variable to
  _APPSIGNAL_APP_ENV to be consistent with the public version.

Update internal agent CLI start command

What does this refer to?

I currently use the appsignal agent in standalone mode as such:

...../ext/appsignal-agent --config appsignal-agent.conf

will this change?

thanks!

@jjb That should still work as expected. 😄

Internally, when the integration's native extension starts the agent, it will start it in "integration mode", which affects how the agent reads environment variables, and how it manages its lifecycle. We recently changed the way in which we tell the agent to start in this mode.

@jjb @unflxw it does have some other changes. Commit for reference (Private link).

For your particular question:

If you want to start the agent as it worked previously you need to run ./appsignal-agent start --config appsignal-agent.conf. Note the addition of the start subcommand.

You can also now run ./appsignal-agent --help for more information about how the CLI works.
