<h3>MODULE</h3>
<div class="REFBODY">supervisor</div>
<h3>MODULE SUMMARY</h3>
<div class="REFBODY">Generic Supervisor Behaviour</div>
<h3>DESCRIPTION</h3>
<div class="REFBODY"><p>
<p>A behaviour module for implementing a supervisor, a process which
supervises other processes called child processes. A child
process can either be another supervisor or a worker process.
Worker processes are normally implemented using one of
the <span class="code">gen_event</span>, <span class="code">gen_fsm</span>, or <span class="code">gen_server</span>
behaviours. A supervisor implemented using this module will have
a standard set of interface functions and include functionality
for tracing and error reporting. Supervisors are used to build an
hierarchical process structure called a supervision tree, a
nice way to structure a fault tolerant application. Refer to
<strong>OTP Design Principles</strong> for more information.</p>
<p>A supervisor assumes the definition of which child processes to
supervise to be located in a callback module exporting a
pre-defined set of functions.</p>
<p>Unless otherwise stated, all functions in this module will fail
if the specified supervisor does not exist or if bad arguments
are given.</p>
</p></div>
<h3><a name="id222700">Supervision Principles</a></h3>
<div class="REFBODY">
<p>The supervisor is responsible for starting, stopping and
monitoring its child processes. The basic idea of a supervisor is
that it should keep its child processes alive by restarting them
when necessary.</p>
<p>The children of a supervisor is defined as a list of
<strong>child specifications</strong>. When the supervisor is started, the child
processes are started in order from left to right according to
this list. When the supervisor terminates, it first terminates
its child processes in reversed start order, from right to left.</p>
<p>A supervisor can have one of the following <strong>restart strategies</strong>:</p>
<ul>
<li>
<p><span class="code">one_for_one</span> - if one child process terminates and
should be restarted, only that child process is affected.</p>
</li>
<li>
<p><span class="code">one_for_all</span> - if one child process terminates and
should be restarted, all other child processes are terminated
and then all child processes are restarted.</p>
</li>
<li>
<p><span class="code">rest_for_one</span> - if one child process terminates and
should be restarted, the 'rest' of the child processes --
i.e. the child processes after the terminated child process
in the start order -- are terminated. Then the terminated
child process and all child processes after it are restarted.</p>
</li>
<li>
<p><span class="code">simple_one_for_one</span> - a simplified <span class="code">one_for_one</span>
supervisor, where all child processes are dynamically added
instances of the same process type, i.e. running the same
code.</p>
<p>The functions <span class="code">delete_child/2</span>
and <span class="code">restart_child/2</span> are invalid for
<span class="code">simple_one_for_one</span> supervisors and will return
<span class="code">{error,simple_one_for_one}</span> if the specified supervisor
uses this restart strategy.</p>
<p>The function <span class="code">terminate_child/2</span> can be used for
children under <span class="code">simple_one_for_one</span> supervisors by
giving the child's <span class="code">pid()</span> as the second argument. If
instead the child specification identifier is used,
<span class="code">terminate_child/2</span> will return
<span class="code">{error,simple_one_for_one}</span>.</p>
<p>Because a <span class="code">simple_one_for_one</span> supervisor could have many
children, it shuts them all down at same time. So, order in which they
are stopped is not defined. For the same reason, it could have an
overhead with regards to the <span class="code">Shutdown</span> strategy.</p>
</li>
</ul>
<p>To prevent a supervisor from getting into an infinite loop of
child process terminations and restarts, a <strong>maximum restart frequency</strong>
is defined using two integer values <span class="code">MaxR</span>
and <span class="code">MaxT</span>. If more than <span class="code">MaxR</span> restarts occur within
<span class="code">MaxT</span> seconds, the supervisor terminates all child
processes and then itself.
</p>
<a name="child_spec"></a>
<p>This is the type definition of a child specification:</p>
<div class="example"><pre>
child_spec() = {Id,StartFunc,Restart,Shutdown,Type,Modules}
Id = term()
StartFunc = {M,F,A}
M = F = atom()
A = [term()]
Restart = permanent | transient | temporary
Shutdown = brutal_kill | int()>0 | infinity
Type = worker | supervisor
Modules = [Module] | dynamic
Module = atom()</pre></div>
<ul>
<li>
<p><span class="code">Id</span> is a name that is used to identify the child
specification internally by the supervisor.</p>
</li>
<li>
<p><span class="code">StartFunc</span> defines the function call used to start
the child process. It should be a module-function-arguments
tuple <span class="code">{M,F,A}</span> used as <span class="code">apply(M,F,A)</span>.</p>
<p>The start function <strong>must create and link to</strong> the child
process, and should return <span class="code">{ok,Child}</span> or
<span class="code">{ok,Child,Info}</span> where <span class="code">Child</span> is the pid of
the child process and <span class="code">Info</span> an arbitrary term which is
ignored by the supervisor.</p>
<p>The start function can also return <span class="code">ignore</span> if the child
process for some reason cannot be started, in which case
the child specification will be kept by the supervisor
(unless it is a temporary child) but the non-existing child
process will be ignored.</p>
<p>If something goes wrong, the function may also return an
error tuple <span class="code">{error,Error}</span>.</p>
<p>Note that the <span class="code">start_link</span> functions of the different
behaviour modules fulfill the above requirements.</p>
</li>
<li>
<p><span class="code">Restart</span> defines when a terminated child process
should be restarted. A <span class="code">permanent</span> child process should
always be restarted, a <span class="code">temporary</span> child process should
never be restarted (even when the supervisor's restart strategy
is <span class="code">rest_for_one</span> or <span class="code">one_for_all</span> and a sibling's
death causes the temporary process to be terminated) and a
<span class="code">transient</span> child process should be restarted only if
it terminates abnormally, i.e. with another exit reason
than <span class="code">normal</span>, <span class="code">shutdown</span> or <span class="code">{shutdown,Term}</span>.</p>
</li>
<li>
<p><span class="code">Shutdown</span> defines how a child process should be
terminated. <span class="code">brutal_kill</span> means the child process will
be unconditionally terminated using <span class="code">exit(Child,kill)</span>.
An integer timeout value means that the supervisor will tell
the child process to terminate by calling
<span class="code">exit(Child,shutdown)</span> and then wait for an exit signal
with reason <span class="code">shutdown</span> back from the child process. If
no exit signal is received within the specified number of milliseconds,
the child process is unconditionally terminated using
<span class="code">exit(Child,kill)</span>.</p>
<p>If the child process is another supervisor, <span class="code">Shutdown</span>
should be set to <span class="code">infinity</span> to give the subtree ample
time to shutdown. It is also allowed to set it to <span class="code">infinity</span>,
if the child process is a worker.</p>
<div class="warning">
<div class="label">Warning</div>
<div class="content"><p>
<p>Be careful by setting the <span class="code">Shutdown</span> strategy to
<span class="code">infinity</span> when the child process is a worker. Because, in this
situation, the termination of the supervision tree depends on the
child process, it must be implemented in a safe way and its cleanup
procedure must always return.</p>
</p></div>
</div>
<p><strong>Important note on simple-one-for-one supervisors:</strong>
The dynamically created child processes of a
simple-one-for-one supervisor are not explicitly killed,
regardless of shutdown strategy, but are expected to terminate
when the supervisor does (that is, when an exit signal from
the parent process is received).</p>
<p>Note that all child processes implemented using the standard
OTP behavior modules automatically adhere to the shutdown
protocol.</p>
</li>
<li>
<p><span class="code">Type</span> specifies if the child process is a supervisor or
a worker.</p>
</li>
<li>
<p><span class="code">Modules</span> is used by the release handler during code
replacement to determine which processes are using a certain
module. As a rule of thumb <span class="code">Modules</span> should be a list
with one element <span class="code">[Module]</span>, where <span class="code">Module</span> is
the callback module, if the child process is a supervisor,
gen_server or gen_fsm. If the child process is an event
manager (gen_event) with a dynamic set of callback modules,
<span class="code">Modules</span> should be <span class="code">dynamic</span>. See <strong>OTP Design Principles</strong>
for more information about release handling.</p>
</li>
<li>
<p>Internally, the supervisor also keeps track of the pid
<span class="code">Child</span> of the child process, or <span class="code">undefined</span> if no
pid exists.</p>
</li>
</ul>

<p>Creates a supervisor process as part of a supervision tree.
The function will, among other things, ensure that
the supervisor is linked to the calling process (its
supervisor).</p>
<p>The created supervisor process calls <span class="code">Module:init/1</span> to
find out about restart strategy, maximum restart frequency
and child processes. To ensure a synchronized start-up
procedure, <span class="code">start_link/2,3</span> does not return until
<span class="code">Module:init/1</span> has returned and all child processes
have been started.</p>
<p>If <span class="code">SupName={local,Name}</span> the supervisor is registered
locally as <span class="code">Name</span> using <span class="code">register/2</span>. If
<span class="code">SupName={global,Name}</span> the supervisor is registered
globally as <span class="code">Name</span> using <span class="code">global:register_name/2</span>. If
<span class="code">SupName={via,Module,Name}</span> the supervisor
is registered as <span class="code">Name</span> using the registry represented by
<span class="code">Module</span>. The <span class="code">Module</span> callback should export the functions
<span class="code">register_name/2</span>, <span class="code">unregister_name/1</span> and <span class="code">send/2</span>,
which should behave like the corresponding functions in <span class="code">global</span>.
Thus, <span class="code">{via,global,Name}</span> is a valid reference.</p>
<p>If no name is provided, the supervisor is not registered.</p>
<p><span class="code">Module</span> is the name of the callback module.</p>
<p><span class="code">Args</span> is an arbitrary term which is passed as
the argument to <span class="code">Module:init/1</span>.</p>
<p>If the supervisor and its child processes are successfully
created (i.e. if all child process start functions return
<span class="code">{ok,Child}</span>, <span class="code">{ok,Child,Info}</span>, or <span class="code">ignore</span>)
the function returns <span class="code">{ok,Pid}</span>, where <span class="code">Pid</span> is
the pid of the supervisor. If there already exists a process
with the specified <span class="code">SupName</span> the function returns
<span class="code">{error,{already_started,Pid}}</span>, where <span class="code">Pid</span> is
the pid of that process.</p>
<p>If <span class="code">Module:init/1</span> returns <span class="code">ignore</span>, this function
returns <span class="code">ignore</span> as well and the supervisor terminates
with reason <span class="code">normal</span>.
If <span class="code">Module:init/1</span> fails or returns an incorrect value,
this function returns <span class="code">{error,Term}</span> where <span class="code">Term</span>
is a term with information about the error, and the supervisor
terminates with reason <span class="code">Term</span>.</p>
<p>If any child process start function fails or returns an error
tuple or an erroneous value, the function returns
<span class="code">{error,shutdown}</span> and the supervisor terminates all
started child processes and then itself with reason
<span class="code">shutdown</span>.</p>

the child specification defined in <span class="code">Module:init/1</span> will

the corresponding child process is running or not.</p>
<p>If the child process start function returns <span class="code">{ok,Child}</span>

the child specification is added to the supervisor, the pid
is set to <span class="code">undefined</span> and the function returns

<p>If the child process start function returns an error tuple or
an erroneous value, or if it fails, the child specification is
discarded and the function returns <span class="code">{error,Error}</span> where
<span class="code">Error</span> is a term containing information about the error
and child specification.</p>

child.</p>
<p>If the supervisor is not <span class="code">simple_one_for_one</span>,
<span class="code">Id</span> must be the child specification
identifier. The process, if there is one, is terminated and,
unless it is a temporary child, the child specification is
kept by the supervisor. The child process may later be
restarted by the supervisor. The child process can also be
restarted explicitly by calling
<span class="code">restart_child/2</span>. Use <span class="code">delete_child/2</span> to remove
the child specification.</p>
<p>If the child is temporary, the child specification is deleted as
soon as the process terminates. This means
that <span class="code">delete_child/2</span> has no meaning
and <span class="code">restart_child/2</span> can not be used for these
children.</p>
<p>If the supervisor is <span class="code">simple_one_for_one</span>, <span class="code">Id</span>
must be the child process' <span class="code">pid()</span>. I the specified
process is alive, but is not a child of the given
supervisor, the function will return
<span class="code">{error,not_found}</span>. If the child specification
identifier is given instead instead of a <span class="code">pid()</span>, the
function will return <span class="code">{error,simple_one_for_one}</span>.</p>
<p>If successful, the function returns <span class="code">ok</span>. If there is
no child specification with the specified <span class="code">Id</span>, the
function returns <span class="code">{error,not_found}</span>.</p>

<p>Whenever a supervisor is started using

the new process to find out about restart strategy, maximum
restart frequency and child specifications.</p>
<p><span class="code">Args</span> is the <span class="code">Args</span> argument provided to the start
function.</p>
<p><span class="code">RestartStrategy</span> is the restart strategy and
<span class="code">MaxR</span> and <span class="code">MaxT</span> defines the maximum restart
frequency of the supervisor. <span class="code">[ChildSpec]</span> is a list of
valid child specifications defining which child processes
the supervisor should start and monitor. See the discussion
about Supervision Principles above.</p>
<p>Note that when the restart strategy is
<span class="code">simple_one_for_one</span>, the list of child specifications
must be a list with one child specification only.
(The <span class="code">Id</span> is ignored). No child process is then started
during the initialization phase, but all children are assumed
to be started dynamically using
<span class="code">supervisor:start_child/2</span>.</p>
