Detailed Description

Supplies common server operations for dynamic and static configuration of services.

The Gestalt embodies the concept of configuration context. On one hand, it is a flat namespace, where names correspond to a Service Object instance. A Gestalt owns the Service Repository instance, which in turn owns the Service Object instances.

Another aspect of a Gestalt is its responsibility for record-keeping and accounting for the meta-data, necessary for locating, removing or instantiating a service.

A repository underlies an instance of a gestalt and its lifetime may or may not be bounded by the lifetime of the gestalt, that owns it. This feature is important for the derived classes and the Service Config in particular.

Member Function Documentation

void ACE_Service_Gestalt::add_processed_static_svc (  const ACE_Static_Svc_Descriptor *  assd  )  [protected]

Captures a list of the direcives processed (explicitely) for this Gestalt so that services can be replicated in other repositories upon their first initialization. This is part of the mechanism ensuring distinct local instances for static service objects, loaded in another repository. When process_directive(Static_Svc_Descriptor&) is called, it associates a service object with the Gestalt and makes the resource (a Service Object) local to the repository. This is but the first step in using such SO. The next is the "initialization" step. It is typicaly done through a "static" service configuration directive. In contrast a "dynamic" directive, when processed through the overloaded process_directives(string) both creates the SO locally and initializes it, where the statics directive must first locate the SO and then calls the init() method. This means that durig the "static" initialization there's no specific information about the hosting repository and the gestalt must employ some lookup strategy to find it elsewhere.

This is the primary entry point into the ACE_Service_Config (the constructor just handles simple initializations). It parses arguments passed in from argc and argv parameters. The arguments that are valid in a call to this method include: '-b' Option to indicate that we should be a daemon. Note that when this option is used, the process will be daemonized before the service configuration file(s) are read. During daemonization, (on POSIX systems) the current directory will be changed to "/" so the caller should either fully specify the file names, or execute a chroot() to the appropriate directory. See also: ACE::daemonize(). '-d' Turn on debugging mode '-f' Specifies a configuration file name other than the default svc.conf. Can be specified multiple times to use multiple files. '-k' Specifies the rendezvous point to use for the ACE distributed logger. '-y' Explicitly enables the use of static services. This flag overrides the ignore_static_svcs parameter value. '-n' Explicitly disables the use of static services. This flag overrides the ignore_static_svcs parameter value. '-p' Specifies a pathname which is used to store the process id. '-s' Specifies a signal number other than SIGHUP to trigger reprocessing of the configuration file(s). Ignored for platforms that do not have POSIX signals, such as Windows. '-S' Specifies a service directive string. Enclose the string in quotes and escape any embedded quotes with a backslash. This option specifies service directives without the need for a configuration file. Parameters: argc  The number of commandline arguments. argv  The array with commandline arguments logger_key  Indicates where to write the logging output, which is typically either a STREAM pipe or a socket address. ignore_static_svcs  If true then static services are not loaded, otherwise, they are loaded. ignore_default_svc_conf_file  If false then the svc.conf configuration file will be ignored. ignore_debug_flag  If false then the application is responsible for setting the ACE_Log_Msg::priority_mask appropriately. Return values: -1  The configuration file is not found or cannot be opened (errno is set accordingly). 0  Success. >0  The number of errors encountered while processing the service configuration file(s).
