2013-04-27Add support for a realtime sorcery module.Joshua Colp
This change does the following: 1. Adds the sorcery realtime module 2. Adds unit tests for the sorcery realtime module 3. Changes the realtime core to use an ast_variable list instead of variadic arguments 4. Changes all realtime drivers to accept an ast_variable list Review: https://reviewboard.asterisk.org/r/2424/ git-svn-id: https://origsvn.digium.com/svn/asterisk/trunk@386731 65c4cc65-6c06-0410-ace0-fbb531ad65f3
2013-04-26Clean up memory leak in config file on off nominal paths when glob is allowedMatthew Jordan
If a system allows for its usage, Asterisk will use glob to help parse Asterisk .conf files. The config file loading routine was leaking the memory allocated by the glob() routine when the config file was in an unmodified or invalid state. This patch properly calls globfree in those off nominal paths.

2013-04-25Merge the pimp_my_sip branch into trunk.Mark Michelson
The pimp_my_sip branch is being merged at this point because it offers basic functionality, and from an API standpoint, things are complete. SIP work is *not* feature-complete; however, with the completion of the SUBSCRIBE/NOTIFY API, all APIs (except a PUBLISH API) have been created, and thus it is possible for developers to attempt to create new SIP work. API documentation can be found in the doxygen in the code, but usability documentation is still lacking. git-svn-id: https://origsvn.digium.com/svn/asterisk/trunk@386540 65c4cc65-6c06-0410-ace0-fbb531ad65f3

2013-04-22This patch adds a RESTful HTTP interface to Asterisk.David M. Lee
The API itself is documented using Swagger, a lightweight mechanism for documenting RESTful API's using JSON. This allows us to use swagger-ui to provide executable documentation for the API, generate client bindings in different languages, and generate a lot of the boilerplate code for implementing the RESTful bindings. The API docs live in the rest-api/ directory. The RESTful bindings are generated from the Swagger API docs using a set of Mustache templates. The code generator is written in Python, and uses Pystache. Pystache has no dependencies, and be installed easily using pip. Code generation code lives in rest-api-templates/. The generated code reduces a lot of boilerplate when it comes to handling HTTP requests. It also helps us have greater consistency in the REST API.

2013-04-18Fix lock errors on startup.David M. Lee
In messages.c, there are several places in the code where we create a tmp_tech_holder and pass that into an ao2_find call. Unfortunately, we weren't initializing the rwlock on the tmp_tech_holder, which the hash function was locking. It's apparently harmless, but still not the best code. This patch extracts all that copy/pasted code into two functions, msg_find_by_tech and msg_find_by_tech_name, which properly initialize and destroy the rwlock on the tmp_tech_holder.

2013-04-16Move device state distribution to Stasis-coreKinsey Moore
In the move from Asterisk's event system to Stasis, this makes distributed device state aggregation always-on, removes unnecessary task processors where possible, and collapses aggregate and non-aggregate states into a single cache for ease of retrieval. This also removes an intermediary step in device state aggregation.

2013-04-15Moved core logic from app_stasis to res_stasisDavid M. Lee
After some discussion on asterisk-dev, it was decided that the bulk of the logic in app_stasis actually belongs in a resource module instead of the application module. This patch does that, leaves the app specific stuff in app_stasis, and fixes up everything else to be consistent with that change. * Renamed test_app_stasis to test_res_stasis * Renamed app_stasis.h to stasis_app.h * This is still stasis application support, even though it's no longer in an app_ module. The name should never have been tied to the type of module, anyways. * Now that json isn't a resource module anymore, moved the ast_channel_snapshot_to_json function to main/stasis_channels.c, where it makes more sense.

2013-04-15DTMF events are now published on a channel's stasis_topic. AMI wasDavid M. Lee
refactored to use these events rather than producing the events directly in channel.c. Finally, the code was added to app_stasis to produce DTMF events on the WebSocket. The AMI events are completely backward compatible, including sending events on transmitted DTMF, and sending DTMF start events. The Stasis-HTTP events are somewhat simplified. Since DTMF start and DTMF send events are generally less useful, Stasis-HTTP will only send events on received DTMF end.

2013-04-08Add multi-channel Stasis messages; refactor Dial AMI events to StasisMatthew Jordan
This patch does the following: * A new Stasis payload has been defined for multi-channel messages. This payload can store multiple ast_channel_snapshot objects along with a single JSON blob. The payload object itself is opaque; the snapshots are stored in a container keyed by roles. APIs have been provided to query for and retrieve the snapshots from the payload object. * The Dial AMI events have been refactored onto Stasis. This includes dial messages in app_dial, as well as the core dialing framework. The AMI events have been modified to send out a DialBegin/DialEnd events, as opposed to the subevent type that was previously used. * Stasis messages, types, and other objects related to channels have been placed in their own file, stasis_channels. Unit tests for some of these objects/messages have also been written. git-svn-id: https://origsvn.digium.com/svn/asterisk/trunk@384910 65c4cc65-6c06-0410-ace0-fbb531ad65f3
2013-04-08Stasis application WebSocket supportDavid M. Lee
This is the API that binds the Stasis dialplan application to external Stasis applications. It also adds the beginnings of WebSocket application support. This module registers a dialplan function named Stasis, which is used to put a channel into the named Stasis app. As a channel enters and leaves the Stasis diaplan application, the Stasis app receives a 'stasis-start' and 'stasis-end' events. Stasis apps register themselves using the stasis_app_register and stasis_app_unregister functions. Messages are sent to an application using stasis_app_send. Finally, Stasis apps control channels through the use of the stasis_app_control object, and the family of stasis_app_control_* functions. Other changes along for the ride are: * An ast_frame_dtor function that's RAII_VAR safe * Some common JSON encoders for name/number, timeval, and context/extension/priority Review: https://reviewboard.asterisk.org/r/2361/ git-svn-id: https://origsvn.digium.com/svn/asterisk/trunk@384879 65c4cc65-6c06-0410-ace0-fbb531ad65f3

2013-04-01stasis: Fixed message ordering issues when forwardingDavid M. Lee
This patch fixes an issue of message ordering that occurs when multiple topics are forwarded to an aggregator topic (such as ast_channel_topic_all()). It is (very reasonably) expected that the rules governing message dispatch order still apply, so long as the messages start from the same thread, and are received by the same subscription. Because the existing code had an additional layer of dispatching via the Stasis thread pool for forwards, those promises couldn't be kept. Forwarding subscriptions no longer have their own mailbox, and now dispatch directly from the forwarding topic's stasis_publish() call. This means that the topic's lock is held for the duration of not only a message's dispatch, but the dispatch of all the forwards. This shouldn't be a problem right now, but if an aggregator topic had many subscribers, it could become a problem. But I figure we can write more clever code when the time comes, if necessary.

2013-03-27AST-2013-002: Prevent denial of service in HTTP serverMatthew Jordan
AST-2012-014, fixed in January of this year, contained a fix for Asterisk's HTTP server for a remotely-triggered crash. While the fix put in place fixed the possibility for the crash to be triggered, a denial of service vector still exists with that solution if an attacker sends one or more HTTP POST requests with very large Content-Length values. This patch resolves this by capping the Content-Length at 1024 bytes. Any attempt to send an HTTP POST with Content-Length greater than this cap will not result in any memory allocation. The POST will be responded to with an HTTP 413 "Request Entity Too Large" response.

2013-03-26Resolve deadlock between pending CDR and batch CDR locksMatthew Jordan
r375757 attempted to resolve a race condition between multiple submissions of CDRs while in batch mode from attempting to destroy the scheduled batch submission by extending the batch CDR lock. Unfortunately, this causes a deadlock between the pending CDR lock and the batch CDR lock. This patch resolves the intent of r375757 by simply providing a new lock that protects the scheduling of the batches. The original batch CDR lock is kept to protect manipulation of the batch CDR settings, but has been placed such that it is not held when the pending lock is held.

2013-03-25Move NewCallerid, HangupRequest and SoftHangupRequest to StasisDavid M. Lee
HangupRequest and SoftHangupRequest are now ast_channel_blob Stasis messages, with the cause code as an optional field in the blob. NewCallerid now simply watches for changes in the callerid information in channel snapshots, and creates the AMI event appropriately. Since the original NewCallerid event honored the channelvars setting in manager.conf, the channel variables configured there had to become a part of the channel snapshot. These are now a part of every snapshot based event, making the configuration description "every time a channel-oriented event is emitted" less of a lie. There a a few other changes wrapped up in here as well. * When ast_channel_topic() is given NULL for a channel, it returns the ast_channel_topic_all() topic instead of NULL. This can clean up a lot of NULL checking we're doing currently. * The fields Cause and Cause-txt were removed from the base channel information and put only on the Hangup events, since those fields are meaningless outside of a Hangup event. * Removed the pipe-delimiter processing of the channelvars field, since that's been deprecated forever.

2013-03-22Move more channel events to Stasis; move res_json.c to main/json.c.David M. Lee
This patch started out simply as fixing the bouncing tests introduced in r382685, but required some other changes to give it a decent implementation. To fix the bouncing tests, the UserEvent and Newexten AMI events needed to be refactored to dispatch via Stasis. Dispatching directly to AMI resulted in those events sometimes getting ahead of the associated Newchannel events, which would understandably confuse anyone. I found that instead of creating a zillion different message types and structures associated with them, it would be preferable to define a message type that has a channel snapshot and a blob of structured data with a small bit of additional information. The JSON object model provides a very nice way of representing structured data, so I went with that. * Move JSON support from res_json.c to main/json.c * Made libjansson-dev a required dependency * Added an ast_channel_blob message type, which has a channel snapshot and JSON blob of data. * Changed UserEvent and Newexten events so that they are dispatched via ast_channel_blob messages on the channel's topic. * Got rid of the ast_channel_varset message; used ast_channel_blob instead. * Extracted the manager functions converting Stasis channel events to AMI events into manager_channel.c.

2013-03-20Resolve a race condition in StasisKinsey Moore
Because of the way that topics were handled when publishing, it was possible to dispatch a message to a subscription after that subscription had been unsubscribed such that the dispatched message arrived at the callback after the callback had received its final message. In callbacks that cleaned up user data, this would often cause a segfault. This has been resolved by locking the topic during the entirety of dispatch. To prevent long publishing and topic locking times, forwarding subscriptions have been made to be standard subscriptions instead of mailboxless subscriptions which were dispatched at publishing time. git-svn-id: https://origsvn.digium.com/svn/asterisk/trunk@383422 65c4cc65-6c06-0410-ace0-fbb531ad65f3

When using scoped locks, the unref of an AO2 object should happen after the unlock occurs which requires usage of scoped refs. git-svn-id: https://origsvn.digium.com/svn/asterisk/trunk@383377 65c4cc65-6c06-0410-ace0-fbb531ad65f3
2013-03-16Transition MWI to Stasis-coreKinsey Moore
Remove MWI's dependency on the event system by moving it to Stasis-core. This also introduces forwarding topic pools in Stasis-core which aggregate many dynamically allocated topics into a single primary topic.

2013-03-15A simplistic router for stasis_message's.David M. Lee
Often times, when subscribing to a topic, one wants to handle different message types differently. While one could cascade if/else statements through the subscription handler, it is much cleaner to specify a different callback for each message type. The stasis_message_router is here to help! A stasis_message_router is constructed for a particular stasis_topic, which is subscribes to. Call stasis_message_router_unsubscribe() to cancel that subscription. Once constructed, routes can be added using stasis_message_router_add() (or stasis_message_router_set_default() for any messages not handled by other routes). There may be only one route per stasis_message_type. The route's callback is invoked just as if it were a callback for a subscription; but it only gets called for messages of the specified type.
