Detailed Description

The jaffar executable: parses a configuration script and either validates it (--dryRun) or builds and runs the search engine via a jaffarPlus::Driver.

Reads the JSON config file named on the command line. In dry-run mode it only constructs the driver to validate the configuration (signalling the construction path via the JAFFAR_IS_DRY_RUN environment variable so host-specific side effects are skipped) and exits. Otherwise it initializes and runs the driver, then reports the exit reason and final step.

Function Documentation

main()

int main	(	int	argc,
		char *	argv[]
	)

Entry point for the jaffar engine executable.

Parses the command line (required configFile and the --dryRun flag), loads and parses the JSON config, and constructs a jaffarPlus::Driver from it. In dry-run mode it sets the JAFFAR_IS_DRY_RUN environment variable before constructing the driver (so host-specific side effects – the NUMA topology check and trace-file loading – are skipped) and returns after successful validation. Otherwise it initializes and runs the driver, maps the resulting jaffarPlus::Driver::exitReason_t to a message, and prints the final step and exit reason.

Parameters

argc	Argument count.
argv	Argument vector.

Returns

The driver's exit reason value (in non-dry-run mode), or 0 after a successful dry run.
