Function Details |
---|
addressGetHost(a)Get the port number of an IPv4 address.
|
addressGetPort(a)Get the port number of an IPv4 address.
|
argRepr(args=(), kwargs={}, max=-1)Return a string representing the given args. |
checkPidRunning(pid)Check if the given pid is currently running.
|
checkPortFree(port)Check if the given local port is free to accept on.
|
checkRemotePort(host, port)Check if the given remote host/port is accepting connections.
|
componentPath(componentName, parentName)Create a path string out of the name of a component and its parent. |
daemonize(stdin='/dev/null', stdout='/dev/null', stderr='/dev/null')This forks the current process into a daemon. The stdin, stdout, and stderr arguments are file names that will be opened and be used to replace the standard file descriptors in sys.stdin, sys.stdout, and sys.stderr. These arguments are optional and default to /dev/null. Note that stderr is opened unbuffered, so if it shares a file with stdout then interleaved output may not appear in the order that you expect. |
deletePidFile(type, name)Delete the pid file in the run directory, using the given process type and process name for the filename. |
ensureDir(dir, description)Ensure the given directory exists, creating it if not. Raises a SystemError if this fails, including the given description. |
formatStorage(units, precision=2)Nicely formats a storage size using SI units. See Wikipedia and other sources for rationale. Prefixes are k, M, G, ... Sizes are powers of 10. Actual result should be suffixed with bit or byte, not b or B.
|
formatTime(seconds)Nicely format time in a human-readable format. Will chunks weeks, days, hours and minutes.
|
getFirstFreePort(startPort)Get the first free port, starting from the given port.
|
getPid(type, name)Get the pid from the pid file in the run directory, using the given process type and process name for the filename.
|
getPidPath(type, name)Get the full path to the pid file for the given process type and name. |
killPid(pid)Send the given process a KILL signal.
|
mergeImplements(*classes)Merge the __implements__ tuples of the given classes into one tuple. |
objRepr(object)Return a string giving the fully qualified class of the given object. |
pathToModuleName(path)Convert the given (relative) path to the python module it would have to be imported as. |
registerPackagePath(packagePath, prefix='flumotion')Register a given path as a path that can be imported from. Used to support partition of bundled code or import code from various uninstalled location. sys.path will also be changed to include this, and remove references to older packagePath's for the same bundle.
|
termPid(pid)Send the given process a TERM signal.
|
version(binary)Print a version block for the flumotion binaries.
|
waitForTerm()Wait until we get killed by a TERM signal (from someone else). |
waitPidFile(type, name)Wait for the given process type and name to have started and created a pid file. Return the pid. |
writePidFile(type, name)Write a pid file in the run directory, using the given process type and process name for the filename. |
