fail2ban.server.jailthread module

class fail2ban.server.jailthread.JailThread

Bases: threading.Thread

Abstract class for threading elements in Fail2Ban.

Attributes

daemon A boolean value indicating whether this thread is a daemon thread (True) or not (False).
ident Thread identifier of this thread or None if it has not been started.
name A string used for identification purposes only.
status Abstract - Should provide status information.
active (bool) Control the state of the thread.
idle (bool) Control the idle state of the thread.
sleeptime (int) The time the thread sleeps for in the loop.

Methods

getName()
isAlive() Return whether the thread is alive.
isDaemon()
is_alive() Return whether the thread is alive.
join([timeout]) Wait until the thread terminates.
run() Abstract - Called when thread starts, thread stops when returns.
setDaemon(daemonic)
setName(name)
start() Sets active flag and starts thread.
stop() Sets active property to False, to flag run method to return.
daemon

A boolean value indicating whether this thread is a daemon thread (True) or not (False).

This must be set before start() is called, otherwise RuntimeError is raised. Its initial value is inherited from the creating thread; the main thread is not a daemon thread and therefore all threads created in the main thread default to daemon = False.

The entire Python program exits when no alive non-daemon threads are left.

getName()
ident

Thread identifier of this thread or None if it has not been started.

This is a nonzero integer. See the thread.get_ident() function. Thread identifiers may be recycled when a thread exits and another thread is created. The identifier is available even after the thread has exited.

isAlive()

Return whether the thread is alive.

This method returns True just before the run() method starts until just after the run() method terminates. The module function enumerate() returns a list of all alive threads.

isDaemon()
is_alive()

Return whether the thread is alive.

This method returns True just before the run() method starts until just after the run() method terminates. The module function enumerate() returns a list of all alive threads.

join(timeout=None)

Wait until the thread terminates.

This blocks the calling thread until the thread whose join() method is called terminates – either normally or through an unhandled exception or until the optional timeout occurs.

When the timeout argument is present and not None, it should be a floating point number specifying a timeout for the operation in seconds (or fractions thereof). As join() always returns None, you must call isAlive() after join() to decide whether a timeout happened – if the thread is still alive, the join() call timed out.

When the timeout argument is not present or None, the operation will block until the thread terminates.

A thread can be join()ed many times.

join() raises a RuntimeError if an attempt is made to join the current thread as that would cause a deadlock. It is also an error to join() a thread before it has been started and attempts to do so raises the same exception.

name

A string used for identification purposes only.

It has no semantics. Multiple threads may be given the same name. The initial name is set by the constructor.

run()

Abstract - Called when thread starts, thread stops when returns.

setDaemon(daemonic)
setName(name)
start()

Sets active flag and starts thread.

status

Abstract - Should provide status information.

stop()

Sets active property to False, to flag run method to return.
