2013-07-29When performing a reload, reload the new features_config and not the oldMatthew Jordan
Performing a module reload of core components causes specific functions compiled into the Asterisk binary to be reloaded. The table of said functions was still pointing to the old features reload mechanism, and not the new one. git-svn-id: https://origsvn.digium.com/svn/asterisk/trunk@395672 65c4cc65-6c06-0410-ace0-fbb531ad65f3
2013-07-27Rename everything Stasis-HTTP to ARIKinsey Moore
This renames all files and API calls from several variants of Stasis-HTTP to ARI including: * Stasis-HTTP -> ARI * STASIS_HTTP -> ARI * stasis_http -> ari (ast_ari for global symbols, file names as well) * stasis http -> ARI Review: https://reviewboard.asterisk.org/r/2706/ (closes issue ASTERISK-22136) git-svn-id: https://origsvn.digium.com/svn/asterisk/trunk@395603 65c4cc65-6c06-0410-ace0-fbb531ad65f3
2013-07-26Remove the unsafe bridge parameter from ast_bridge_hook_callback's.Richard Mudgett
Most hook callbacks did not need the bridge parameter. The pointer value could become invalid if the channel is moved to another bridge while it is executing. * Fixed some issues in feature_attended_transfer() as a result. * Reduce the bridge inhibit count in attended_transfer_properties_shutdown() after it has restored the bridge channel hooks. * Removed basic bridge requirement on feature_blind_transfer(). It does not require the basic bridge like feature_attended_transfer(). git-svn-id: https://origsvn.digium.com/svn/asterisk/trunk@395574 65c4cc65-6c06-0410-ace0-fbb531ad65f3
2013-07-26Improved feature limits interval hook implementaion.Richard Mudgett
* Fixed feature limits to not use special members of struct ast_bridge_features. * Fixed memory leak in off nominal paths of bridge_builtin_set_limits(). * Fixed off nominal path in ast_bridge_features_limits_construct() freeing unallocated memory if it was not called by bridge_builtin_set_limits(). * Made bridge_builtin_interval_features.so unloadable. * Simplified parking's use of its duration interval hook. * Made BridgeWait S option not depend upon another module being loaded.

2013-07-25A great big renaming patchMatthew Jordan
This patch renames the bridging* files to bridge*. This may seem pedantic and silly, but it fits better in line with current Asterisk naming conventions: * channel is not "channeling" * monitor is not "monitoring" etc. A bridge is an object. It is a first class citizen in Asterisk. "Bridging" is the act of using a bridge on a set of channels - and the API that fulfills that role is more than just the action.

* Reduced the number of hook containers to just dtmf_hooks, interval_hooks, and other_hooks. As a result, several functions dealing with the different hook containers could be combined. * Extended the generic hook struct for DTMF and interval hooks instead of using a variant record. * Merged the special talk detector hook into the other_hooks container. * Replaced ast_bridge_features_set_talk_detector() with ast_bridge_talk_detector_hook().

2013-07-23Restore chan_dahdi native bridging and PRI tromboned call elimination.Richard Mudgett
Created a native_dahdi bridging technology for use with the new bridging API. The new bridging technology is part of the chan_dahdi channel driver because it is very specific to that driver. Rather than include the new code directly into chan_dahdi.c the new bridge technology is in its own file and linked into chan_dahdi.so. A large part of this change is the mechanical process of moving declarations around so chan_dahdi.c can be split up into more files later. * Changed the bridging core to pass NULL frames into the channel technologies instead of discarding them. The channel technologies may need the proding to determine if their configuration is still valid.

2013-07-23Kill the zombiesMatthew Jordan
In previous versions of Asterisk, the zombies roamed freely, unchecked and uncontrolled. They ravaged Asterisk systems with their biting and their nashing and their pointy teeth. Sometimes, you couldn't even hang them up. Now, zombies are rare. They still *technically* exist in certain places, but they are controlled. Kind of like a zombie zoo: you can see them, but you can't touch them, and they can't touch you. Bring your kids! Because zombies are now population controlled with a very short lifespan, there's no reason to rename the channels to '%s<ZOMBIE>'. The channels are guaranteed to die off quickly; the rename really is just confusing at this point. This patch finally removes the renaming. On the plus side: this made my life easier in CDRs during call pickup and attended transfers to an Asterisk application. It will make other folks lives easier as well!

2013-07-23Fix bridge/channel AMI event ordering issuesDavid M. Lee
The stasis_cache_update messages are somewhat cumbersome to handle with the stasis_message_router. Since all updates have the same message type, they are normally handled with the same route. Since caching itself is a first class component of stasis-core, it makes sense for the router to handle the cache update messages itself. This patch adds stasis_message_router_add_cache_update() and stasis_message_router_remove_cache_update() to handle the routing of stasis_cache_update messages. This patch also corrects an issue with manager_{bridging,channels}.c, where events might be reordered. The reordering occurs because the components use different message routers, which they needed because they both needed to route cache update messages. They now both use manager's router, and add cache routes for just the cache updates they are interested in.

2013-07-21Tolerate presence of RFC2965 Cookie2 header by ignoring itMatthew Jordan
This patch modifies parsing of cookies in Asterisk's http server by doing an explicit comparison of the "Cookie" header instead of looking at the first 6 characters to determine if the header is a cookie header. This avoids parsing "Cookie2" headers and overwriting the previously parsed "Cookie" header. Note that we probably should be appending the cookies in each "Cookie" header to the parsed results; however, while clients can send multiple cookie headers they never really do. While this patch doesn't improve Asterisk's behavior in that regard, it shouldn't make it any worse either. Note that the solution in this patch was pointed out on the issue by the issue reporter, Stuart Henderson.

This adds CEL support for blind and attended transfers and call pickup. During the course of adding this functionality I noticed that CONF_ENTER, CONF_EXIT, and BRIDGE_TO_CONF events are particularly useless without a bridge identifier, so I added that as well. This adds tests for blind transfers, several types of attended transfers, and call pickup. The extra field in CEL records now consists of a JSON blob whose fields are defined on a per-event basis.

2013-07-18Fix caching topic shutdown assertionsDavid M. Lee
The recent changes to update stasis_cache_topics directly from the publisher thread uncovered a race condition, which was causing asserts in the /stasis/core tests. If the caching topic's subscription is the last reference to the caching topic, it will destroy the caching topic after the final message has been processed. When dispatching to a different thread, this usually gave the unsubscribe enough time to finish before destruction happened. Now, however, it consistently destroys before unsubscription is complete. This patch adds an extra reference to the caching topic, to hold it for the duration of the unsubscription. This patch also removes an extra unref that was happening when the final message was received by the caching topic. It was put there because of an extra ref that was put into the caching topic's constructor. Both have been removed, which makes the destructor a bit less confusing.

To avoid some locking issues with the agent holding bridge, I needed to make some changes to the after bridge callback support. The after bridge callback is now a list of requested callbacks with the last to be added the only active callback. The after bridge callback for failed callbacks will always happen in the channel thread when the channel leaves the bridging system or is destroyed.

2013-07-14Remove redundant code in dns.cMatthew Jordan
Peter J Philipp pointed out that there are two checks that ensure that len is not less than 0. If len is less than 0, the function returns. Having both of them is clearly redundant. This removes the second and attempts to clarify (slightly) the error condition.
