Development notes

Note

2004-11-25: Persistent Dynamic Members added by: NetNation Communications (www.netnation.com) Kevin Lindsay kevin.nosp@m.l@ne.nosp@m.tnati.nosp@m.on.c.nosp@m.om

Each dynamic agent in each queue is now stored in the astdb. When asterisk is restarted, each agent will be automatically readded into their recorded queues. This feature can be configured with the 'persistent_members=<1|0>' setting in the '[general]' category in queues.conf. The default is on.

Note

2004-06-04: Priorities in queues added by inAccess Networks (work funded by Hellas On Line (HOL) www.hol.gr).

These features added by David C. Troy dave@.nosp@m.toad.nosp@m..net:

• Per-queue holdtime calculation
• Estimated holdtime announcement
• Position announcement
• Abandoned/completed call counters
• Failout timer passed as optional app parameter

Patch Version 1.07 2003-12-24 01

Added servicelevel statistic by Michiel Betel michi.nosp@m.el@b.nosp@m.etel..nosp@m.nl Added Priority jumping code for adding and removing queue members by Jonathan Stanton aster.nosp@m.isk@.nosp@m.doilo.nosp@m.okli.nosp@m.keica.nosp@m.re.c.nosp@m.om

Fixed to work with CVS as of 2004-02-25 and released as 1.07a by Matthew Enger m.eng.nosp@m.er@x.nosp@m.i.com.nosp@m..au

Please read before modifying this file.

There are three locks which are regularly used throughout this file, the queue list lock, the lock for each individual queue, and the interface list lock. Please be extra careful to always lock in the following order 1) queue list lock 2) individual queue lock 3) interface list lock This order has sort of "evolved" over the lifetime of this application, but it is now in place this way, so please adhere to this order!

clear_stats()

static int clear_stats ( const char *  queuename )

static

Facilitates resetting statistics for a queue.

This function actually does not reset any statistics, but rather finds a call_queue struct which corresponds to the passed-in queue name and passes that structure to the clear_queue function. If no queuename is passed in, then all queues will have their statistics reset.

Parameters

queuename

The name of the queue to reset the statistics for. If this is NULL or zero-length, then this means to reset the statistics for all queues

Return values

0

Note

Load from realtime before taking the "queues" container lock, to avoid blocking all queue operations while waiting for the DB.

This will be two separate database transactions, so we might see queue parameters as they were before another process changed the queue and member list as it was after the change. Thus we might see an empty member list when a queue is deleted. In practise, this is unlikely to cause a problem.

Reload a single queue via realtime.

Check for statically defined queue first, check if deleted RT queue, check for new RT queue, if queue vars are not defined init them with defaults. reload RT queue vars, set RT queue members dead and reload them, return finished queue.

Return values

the	queue,
NULL	if it doesn't exist.

Note

Should be called with the "queues" container locked.

Note

Hmm, can't seem to distinguish a DB failure from a not found condition... So we might delete an in-core queue in case of DB failure.

is_our_turn()

static int is_our_turn ( struct queue_ent *  qe )

static

Check if we should start attempting to call queue members.

A simple process, really. Count the number of members who are available to take our call and then see if we are in a position in the queue at which a member could accept our call.

Parameters

[in]

qe

The caller who wants to know if it is his turn

Return values

0	It is not our turn
1	It is our turn

Load the module.

Module loading including tests for configuration or dependencies. This function can return AST_MODULE_LOAD_FAILURE, AST_MODULE_LOAD_DECLINE, or AST_MODULE_LOAD_SUCCESS. If a dependency or environment variable fails tests return AST_MODULE_LOAD_FAILURE. If the module can not load the configuration file or other non-critical problem return AST_MODULE_LOAD_DECLINE. On success return AST_MODULE_LOAD_SUCCESS.

queue_exec()

static int queue_exec ( struct ast_channel *  chan, const char *  data  )

The starting point for all queue calls.

The process involved here is to

1. Parse the options specified in the call to Queue()
2. Join the queue
3. Wait in a loop until it is our turn to try calling a queue member
4. Attempt to call a queue member
5. If 4. did not result in a bridged call, then check for between call options such as periodic announcements etc.
6. Try 4 again unless some condition (such as an expiration time) causes us to exit the queue.

Configure a queue parameter.

The failunknown flag is set for config files (and static realtime) to show errors for unknown parameters. It is cleared for dynamic realtime to allow extra fields in the tables.

Note

For error reporting, line number is passed for .conf static configuration, for Realtime queues, linenum is -1.

The command center for all reload operations.

Whenever any piece of queue information is to be reloaded, this function is called. It interprets the flags set in the mask parameter and acts based on how they are set.

Parameters

reload	True if we are reloading information, false if we are loading information for the first time.
mask	A bitmask which tells the handler what actions to take
queuename	The name of the queue on which we wish to take action

Return values

0	All reloads were successful
non-zero	There was a failure

reload_queues()

static int reload_queues ( int  reload, struct ast_flags *  mask, const char *  queuename  )

static

reload the queues.conf file

This function reloads the information in the general section of the queues.conf file and potentially more, depending on the value of mask.

Parameters

reload	0 if we are calling this the first time, 1 every other time
mask	Gives flags telling us what information to actually reload
queuename	If set to a non-zero string, then only reload information from that particular queue. Otherwise inspect all queues

Return values

-1	Failure occurred
0	All clear!

Reload information pertaining to a particular queue.

Once we have isolated a queue within reload_queues, we call this. This will either reload information for the queue or if we're just reloading member information, we'll just reload that without touching other settings within the queue

Parameters

cfg	The configuration which we are reading
mask	Tells us what information we need to reload
queuename	The name of the queue we are reloading information from

Does error checking before attempting to request a channel and call a member. This function is only called from ring_one(). Failure can occur if:

• Agent on call
• Agent is paused
• Wrapup time not expired
• Priority by another queue

Return values

1	on success to reach a free agent
0	on failure to get agent.

Place a call to a queue member.

Once metrics have been calculated for each member, this function is used to place a call to the appropriate member (or members). The low-level channel-handling and error detection is handled in ring_entry

Return values

1	if a member was called successfully
0	otherwise

Wait for a member to answer the call.

Parameters

[in]	qe	the queue_ent corresponding to the caller in the queue
[in]	outgoing	the list of callattempts. Relevant ones will have their chan and stillgoing parameters non-zero
[in]	to	the amount of time (in milliseconds) to wait for a response
[out]	digit	if a user presses a digit to exit the queue, this is the digit the caller pressed
[in]	prebusies	number of busy members calculated prior to calling wait_for_answer
[in]	caller_disconnect	if the 'H' option is used when calling Queue(), this is used to detect if the caller pressed * to disconnect the call
[in]	forwardsallowed	used to detect if we should allow call forwarding, based on the 'i' option to Queue()

Todo:

eventually all call forward logic should be integrated into and replaced by ast_call_forward()

wait_our_turn()

static int wait_our_turn ( struct queue_ent *  qe, int  ringing, enum queue_result *  reason  )

static

The waiting areas for callers who are not actively calling members.

This function is one large loop. This function will return if a caller either exits the queue or it becomes that caller's turn to attempt calling queue members. Inside the loop, we service the caller with periodic announcements, holdtime announcements, etc. as configured in queues.conf

Return values

0	if the caller's turn has arrived
-1	if the caller should exit the queue.

word_in_list()

static int word_in_list ( const char *  list, const char *  word  )

static

Check if a given word is in a space-delimited list.

Parameters

list	Space delimited list of words
word	The word used to search the list

Note

This function will not return 1 if the word is at the very end of the list (followed immediately by a \0, not a space) since it is used for checking tab-completion and a word at the end is still being tab-completed.

Return values

1	if the word is found
0	if the word is not found
