Kevin P. Fleming	73743b77b0	Add 'bitflags'-style information elements to event framework This patch add a new payload type for information elements, a set of bit flags. The payload is transported as a 32-bit unsigned integer but when matching is performed between events and subscribers, the matching is done by using a bitwise AND instead of numeric value comparison.

Russell Bryant	ee77b475f2	Improve performance of the ast_event cache functionality. This code comes from svn/asterisk/team/russell/event_performance/. Here is a summary of the changes that have been made, in order of both invasiveness and performance impact, from smallest to largest. 1) Asterisk 1.6.1 introduces some additional logic to be able to handle distributed device state. This functionality comes at a cost. One relatively minor change in this patch is that the extra processing required for distributed device state is now completely bypassed if it's not needed. 2) One of the things that I noticed when profiling this code was that a _lot_ of time was spent doing string comparisons. I changed the way strings are represented in an event to include a hash value at the front. So, before doing a string comparison, we do an integer comparison on the hash. 3) Finally, the code that handles the event cache has been re-written. I tried to do this in a such a way that it had minimal impact on the API. I did have to change one API call, though - ast_event_queue_and_cache(). However, the way it works now is nicer, IMO. Each type of event that can be cached (MWI, device state) has its own hash table and rules for hashing and comparing objects. This by far made the biggest impact on performance. For additional details regarding this code and how it was tested, please see the review request.

Russell Bryant	823d1c7ea9	Merge some more changes from team/russell/events This commit pulls in a batch of improvements and additions to the event API. Changes include: - the ability to dynamically build a subscription. This is useful if you're building a subscription based on something you receive from the network, or from options in a configuration file. - Add tables of event types and IE types and the corresponding string representation for implementing text based protocols that use these events, for showing events on the CLI, reading configuration that references event information, among other things. - Add a table that maps IE types and the corresponding payload type. - an API call to get the total size of an event - an API call to get all events from the cache that match a subscription - a new IE payload type, raw, which I used for transporting the Entity ID in my code for handling distributed device state. - Code improvements to reduce code duplication - Include the Entity ID of the server that originated the event in every event - an additional event type, DEVICE_STATE_CHANGE, to help facilitate distributed device state. DEVICE_STATE is a state change on one server, DEVICE_STATE_CHANGE is the aggregate device state change across all servers. git-svn-id: https://origsvn.digium.com/svn/asterisk/trunk@121555 65c4cc65-6c06-0410-ace0-fbb531ad65f3	18 years ago

Steve Murphy	8b6d8da58c	Introducing a small optimization to event_unsubscribe; events now use a Doubly-Linked list for events, gives fast deletions, for the sake of channel driver mwi events.

Mark Michelson	23fc97480e	Fix a small logic error in ast_event_iterator_next. The previous logic allowed for the iterator to indicate there was more data than there really was, causing the iterator read beyond the end of the event structure. This led to invalid memory reads and potential crashes. git-svn-id: https://origsvn.digium.com/svn/asterisk/trunk@103559 65c4cc65-6c06-0410-ace0-fbb531ad65f3	18 years ago
Mark Michelson	9d683be81a	Fix a problem regarding network vs. host byte order in the event API. ast_event_iterator_get_ie_type should return the ie type in host byte order. Furthermore, ast_event_get_ie_raw should already have its ie type argument in host byte order since it could be called externally (and it in fact is called in this way by ast_event_get_cached). git-svn-id: https://origsvn.digium.com/svn/asterisk/trunk@103282 65c4cc65-6c06-0410-ace0-fbb531ad65f3	18 years ago

Luigi Rizzo	fdb7f7ba3d	Start untangling header inclusion in a way that does not affect build times - tested, there is no measureable difference before and after this commit. In this change: use asterisk/compat.h to include a small set of system headers: inttypes.h, unistd.h, stddef.h, stddint.h, sys/types.h, stdarg.h, stdlib.h, alloca.h, stdio.h Where available, the inclusion is conditional on HAVE_FOO_H as determined by autoconf. Normally, source files should not include any of the above system headers, and instead use either "asterisk.h" or "asterisk/compat.h" which does it better. For the time being I have left alone second-level directories (main/db1-ast, etc.). git-svn-id: https://origsvn.digium.com/svn/asterisk/trunk@89333 65c4cc65-6c06-0410-ace0-fbb531ad65f3	18 years ago

Joshua Colp	2351d789fd	Add API calls for iterating through an event.

Russell Bryant	e113d36aa4	Merge a set of device state improvements from team/russell/events. The way a device state change propagates is kind of silly, in my opinion. A device state provider calls a function that indicates that the state of a device has changed. Then, another thread goes back and calls a callback for the device state provider to find out what the new state is before it can go send it off to whoever cares. I have changed it so that you can include the state that the device has changed to in the first function call from the device state provider. This removes the need to have to call the callback, which locks up critical containers to go find out what the state changed to. This change set changes the "simple" device state providers to use the new method. This includes parking, meetme, and SLA. I have also mostly converted chan_agent in my branch, but still have some more things to think through before presenting the plan for converting channel drivers to ensure all of the right events get generated ... git-svn-id: https://origsvn.digium.com/svn/asterisk/trunk@79027 65c4cc65-6c06-0410-ace0-fbb531ad65f3	18 years ago

Russell Bryant	b6b1bf3213	Merge changes from team/russell/events This set of changes introduces a new generic event API for use within Asterisk. I am still working on a way for events to be shared between servers, but this part is ready and can already be used inside of Asterisk. This set of changes introduces the first use of the API, as well. I have restructured the way that MWI (message waiting indication) is handled. It is now event based instead of polling based. For example, if there are a bunch of SIP phones subscribed to mailboxes, then chan_sip will not have to constantly poll the mailboxes for changes. app_voicemail will generate events when changes occur. See UPGRADE.txt and CHANGES for some more information on the effects of these changes from the user perspective. For developer information, see the text in include/asterisk/event.h. As always, additional feedback is welcome on the asterisk-dev mailing list. git-svn-id: https://origsvn.digium.com/svn/asterisk/trunk@62292 65c4cc65-6c06-0410-ace0-fbb531ad65f3	19 years ago
