This is based (very) loosely on an internal script to start the
daemon. It accepts a configuration and starts the daemon.
To accommodate the configuration, a number of miscellaneous changes
have been made.
The vanilla configuration shows the concept, but it has not yet been
fully implemented; that'll likely happen at a later date. Until then,
the existing environment-variable-based configuration will be used.
* bin/server.js: Add file.
* conf/vanilla-server.json: Example configuration added.
* src/server/daemon/Daemon.js (_httpPort): Remove field.
(_conf): Add field.
(__construct): [BC BREAK] Accept conf instead of port and log
priority. Move initialization code into `start'.
(start): [BC BREAK] Initialization code moved here. Now returns
promise for entire daemon, which will error in the event of an
error starting. Move existing code into `_startDaemon'.
(_startDaemon): Old `start' code. Invoked after `start'
initialization.
(_createDebugLog, _createAccessLog): Use configuration. Return
promise.
(_initHttpServer): Use configuration.
(_httpError): Add function to output error and exit. Extracted from
`_initHttpServer'.
* src/server/daemon/scripts.js: [BC BREAK] Append "program/" to
`LV_LEGACY_PATH' so that it can be re-used for script lookups
rather than using the cwd. This removes the need of the cwd being
the legacy src path.
