t.s._.UnixApplicationRunner(app.ApplicationRunner) : class documentation

Part of twisted.scripts._twistd_unix View Source View In Hierarchy

An ApplicationRunner which does Unix-specific things, like fork, shed privileges, and maintain a PID file.
Method preApplication Do pre-application-creation setup.
Method postApplication To be called after the application is created: start the application and run the reactor. After the reactor stops, clean up PID files and such.
Method removePID Remove the specified PID file, if possible. Errors are logged, not raised.
Method setupEnvironment Set the filesystem root, the working directory, and daemonize.
Method shedPrivileges Change the UID and GID or the EUID and EGID of this process.
Method startApplication Configure global process state based on the given application and run the application.

Inherited from ApplicationRunner:

Method __init__ Undocumented
Method run Run the application.
Method startReactor Run the reactor with the given configuration. Subclasses should probably call this from postApplication.
Method createOrGetApplication Create or load an Application based on the parameters found in the given ServerOptions instance.
def preApplication(self): (source)
Do pre-application-creation setup.
def postApplication(self): (source)
To be called after the application is created: start the application and run the reactor. After the reactor stops, clean up PID files and such.
def removePID(self, pidfile): (source)
Remove the specified PID file, if possible. Errors are logged, not raised.
ParameterspidfileThe path to the PID tracking file. (type: str )
def setupEnvironment(self, chroot, rundir, nodaemon, umask, pidfile): (source)
Set the filesystem root, the working directory, and daemonize.
ParameterschrootIf not None, a path to use as the filesystem root (using os.chroot). (type: str or NoneType )
rundirThe path to set as the working directory. (type: str )
nodaemonA flag which, if set, indicates that daemonization should not be done. (type: bool )
umaskThe value to which to change the process umask. (type: int or NoneType )
pidfileIf not None, the path to a file into which to put the PID of this process. (type: str or NoneType )
def shedPrivileges(self, euid, uid, gid): (source)
Change the UID and GID or the EUID and EGID of this process.
ParameterseuidA flag which, if set, indicates that only the effective UID and GID should be set. (type: bool )
uidIf not None, the UID to which to switch. (type: int or NoneType )
gidIf not None, the GID to which to switch. (type: int or NoneType )
def startApplication(self, application): (source)
Configure global process state based on the given application and run the application.
ParametersapplicationAn object which can be adapted to service.IProcess and service.IService.
