|
|
* @{
|
|
* \page PJSIP PJSIP Threading Model
|
|
*
|
|
* There are three major types of threads that SIP will have to deal with:
|
|
* \li Asterisk threads
|
|
* \li PJSIP threads
|
|
* \li SIP threadpool threads (a.k.a. "servants")
|
|
*
|
|
* \par Asterisk Threads
|
|
*
|
|
* Asterisk threads are those that originate from outside of SIP but within
|
|
* Asterisk. The most common of these threads are PBX (channel) threads and
|
|
* the autoservice thread. Most interaction with these threads will be through
|
|
* channel technology callbacks. Within these threads, it is fine to handle
|
|
* Asterisk data from outside of SIP, but any handling of SIP data should be
|
|
* left to servants, \b especially if you wish to call into PJSIP for anything.
|
|
* Asterisk threads are not registered with PJLIB, so attempting to call into
|
|
* PJSIP will cause an assertion to be triggered, thus causing the program to
|
|
* crash.
|
|
*
|
|
* \par PJSIP Threads
|
|
*
|
|
* PJSIP threads are those that originate from handling of PJSIP events, such
|
|
* as an incoming SIP request or response, or a transaction timeout. The role
|
|
* of these threads is to process information as quickly as possible so that
|
|
* the next item on the SIP socket(s) can be serviced. On incoming messages,
|
|
* Asterisk automatically will push the request to a servant thread. When your
|
|
* module callback is called, processing will already be in a servant. However,
|
|
* for other PJSIP events, such as transaction state changes due to timer
|
|
* expirations, your module will be called into from a PJSIP thread. If you
|
|
* are called into from a PJSIP thread, then you should push whatever processing
|
|
* is needed to a servant as soon as possible. You can discern if you are currently
|
|
* in a SIP servant thread using the \ref ast_sip_thread_is_servant function.
|
|
*
|
|
* \par Servants
|
|
*
|
|
* Servants are where the bulk of SIP work should be performed. These threads
|
|
* exist in order to do the work that Asterisk threads and PJSIP threads hand
|
|
* off to them. Servant threads register themselves with PJLIB, meaning that
|
|
* they are capable of calling PJSIP and PJLIB functions if they wish.
|
|
*
|
|
* \par Serializer
|
|
*
|
|
* Tasks are handed off to servant threads using the API call \ref ast_sip_push_task.

|
* The first parameter of this call is a serializer. If this pointer
|
|
* is NULL, then the work will be handed off to whatever servant can currently handle
|
|
* the task. If this pointer is non-NULL, then the task will not be executed until
|
|
* previous tasks pushed with the same serializer have completed. For more information
|
|
* on serializers and the benefits they provide, see \ref ast_threadpool_serializer
|
|
*
|
|
* \par Scheduler
|
|
*
|
|
* Some situations require that a task run periodically or at a future time. Normally
|
|
* the ast_sched functionality would be used but ast_sched only uses 1 thread for all
|
|
* tasks and that thread isn't registered with PJLIB and therefore can't do any PJSIP
|
|
* related work.
|
|
*
|
|
* ast_sip_sched uses ast_sched only as a scheduled queue. When a task is ready to run,
|
|
* it's pushed to a Serializer to be invoked asynchronously by a Servant. This ensures
|
|
* that the task is executed in a PJLIB registered thread and allows the ast_sched thread
|
|
* to immediately continue processing the queue. The Serializer used by ast_sip_sched
|
|
* is one of your choosing or a random one from the res_pjsip pool if you don't choose one.
|
|
*
|
|
* \note
|
|
*
|
|
* Do not make assumptions about individual threads based on a corresponding serializer.
|
|
* In other words, just because several tasks use the same serializer when being pushed
|
|
* to servants, it does not mean that the same thread is necessarily going to execute those
|
|
* tasks, even though they are all guaranteed to be executed in sequence.

|
|
*
|

|
|
* The point of the serializer BTW is not to prevent parallel executions of the SAME task.

* time as other work using the same serializer, whether or not it's being run by the scheduler.

* \par Interval

* The interval is used to calculate the next time the task should run. There are two models.

|
*
|
|
* \ref AST_SIP_SCHED_TASK_PERIODIC specifies that the invocations of the task occur at the
|
|
* specific interval. That is, every \p interval milliseconds, regardless of how long the task
|
|
* takes. If the task takes longer than \p interval, it will be scheduled at the next available
|
|
* multiple of \p interval. For example: If the task has an interval of 60 seconds and the task
|
|
* takes 70 seconds, the next invocation will happen at 120 seconds.
|
|
*
|
|
* \ref AST_SIP_SCHED_TASK_DELAY specifies that the next invocation of the task should start
|
|
* at \p interval milliseconds after the current invocation has finished.

* This function creates and returns a locked, and referenced counted pjsip
|
|
* dialog object. The caller is thus responsible for freeing the allocated
|
|
* memory, decrementing the reference, and releasing the lock when done with
|
|
* the returned object.
|
|
*
|
|
* \note The safest way to unlock the object, and decrement its reference is by
|
|
* calling pjsip_dlg_dec_lock. Alternatively, pjsip_dlg_dec_session can be
|
|
* used to decrement the reference only.
|
|
*
|
|
* The dialog is returned locked and with a reference in order to ensure that the
|
|
* dialog object, and any of its associated objects (e.g. transaction) are not
|
|
* untimely destroyed. For instance, that could happen when a transport error
|
|
* occurs.
|
|
*
|
|
* As long as the caller maintains a reference to the dialog there should be no
|
|
* worry that it might unknowingly be destroyed. However, once the caller unlocks
|
|
* the dialog there is a danger that some of the dialog's internal objects could
|
|
* be lost and/or compromised. For example, when the aforementioned transport error
|
|
* occurs the dialog's associated transaction gets destroyed (see pjsip_dlg_on_tsx_state
|
|
* in sip_dialog.c, and mod_inv_on_tsx_state in sip_inv.c).
|
|
*
|
|
* In this case and before using the dialog again the caller should re-lock the
|
|
* dialog, check to make sure the dialog is still established, and the transaction
|
|
* still exists and has not been destroyed.

|
|
endpoint/"Bob" <sip[s]:host>

|
endpoint/host
|

|
|
* \verbatim
|
|
<sip[s]:host>
|
|
<sip[s]:user@host>
|
|
"Bob" <sip[s]:host>
|

"Bob" <sip[s]:user@host>
|
|
sip[s]:host
|
|
sip[s]:user@host
|
|

|
|
* \verbatim
|
|
host
|
|
user@host
|
|
\endverbatim
|
|
*
|
|
* This form is similar to a dialstring:
|
|
* \verbatim
|
|
PJSIP/user@endpoint
|
|
\endverbatim
|
|
*
|
|
* In this case, the user will be added to the endpoint contact's URI.
|
|
* If the contact URI already has a user, it will be replaced.

|
*
|
|
* The ones that have the sip[s] scheme are the easiest to parse.
|
