David M. Lee	9bed50db41	optional_api: Fix linking problems between modules that export global symbols With the new work in Asterisk 12, there are some uses of the optional_api that are prone to failure. The details are rather involved, and captured on [the wiki][1]. This patch addresses the issue by removing almost all of the magic from the optional API implementation. Instead of relying on weak symbol resolution, a new optional_api.c module was added to Asterisk core. For modules providing an optional API, the pointer to the implementation function is registered with the core. For modules that use an optional API, a pointer to a stub function, along with a optional_ref function pointer are registered with the core. The optional_ref function pointers is set to the implementation function when it's provided, or the stub function when it's now. Since the implementation no longer relies on magic, it is now supported on all platforms. In the spirit of choice, an OPTIONAL_API flag was added, so we can disable the optional_api if needed (maybe it's buggy on some bizarre platform I haven't tested on) The AST_OPTIONAL_API() macros themselves remained unchanged, so existing code could remain unchanged. But to help with debugging the optional_api, the patch limits the #include of optional API's to just the modules using the API. This also reduces resource waste maintaining optional_ref pointers that aren't used. Other changes made as a part of this patch: The stubs for http_websocket that wrap system calls set errno to ENOSYS. * res_http_websocket now properly increments module use count. * In loader.c, the while() wrappers around dlclose() were removed. The while(!dlclose()) is actually an anti-pattern, which can lead to infinite loops if the module you're attempting to unload exports a symbol that was directly linked to. * The special handling of nonoptreq on systems without weak symbol support was removed, since we no longer rely on weak symbols for optional_api.

David M. Lee	7f547872e4	ARI: Implement /recordings/stored API's his patch implements the ARI API's for stored recordings. While the original task only specified deleting a recording, it was simple enough to implement the GET for all recordings, and for an individual recording. The recording playback operation was modified to use the same code for accessing the recording as the REST API, so that they will behave consistently. There were several problems with the api-docs that were also fixed, bringing the ARI spec in line with the implementation. There were some 'wishful thinking' fields on the stored recording model (duration and timestamp) that were removed, because I ended up not implementing a metadata file to go along with the recording to store such information. The GET /recordings/live operation was removed, since it's not really that useful to get a list of all recordings that are currently going on in the system. (At least, if we did that, we'd probably want to also list all of the current playbacks. Which seems weird.) (closes issue ASTERISK-21582) Review: https://reviewboard.asterisk.org/r/2693/ ........

David M. Lee	7a581537e8	ARI: Correct error codes for bridge operations This patch adds error checking to ARI bridge operations, when adding/removing channels to/from bridges. In general, the error codes fall out as follows: * Bridge not found - 404 Not Found * Bridge not in Stasis - 409 Conflict * Channel not found - 400 Bad Request * Channel not in Stasis - 422 Unprocessable Entity * Channel not in this bridge (on remove) - 422 Unprocessable Entity (closes issue ASTERISK-22036) Review: https://reviewboard.asterisk.org/r/2769/ git-svn-id: https://origsvn.digium.com/svn/asterisk/trunk@397565 65c4cc65-6c06-0410-ace0-fbb531ad65f3	12 years ago
Jonathan Rose	21e22310c7	ARI: Music on Hold/Background Music for bridges Adds ARI functions to be able to turn on/off music on hold in a bridge. It actually functions more as a background music without further actions on the bridge since if the rest of the channels in the bridge aren't explicitly muted, they will still be able to communicate.

David M. Lee	5762c1b4ac	ARI: Correct segfault with /variable calls are missing ?variable parameter. Both /asterisk/variable and /channel/{channelId}/variable requires a ?variable parameter to be passed into the query. But we weren't checking for the parameter being missing, which caused a segfault. All calls now properly return 400 Bad Request errors when the parameter is missing. The Swagger api-docs were updated accordingly.

David M. Lee	987fdfb444	ARI: allow other operations to happen while bridged This patch changes ARI bridging to allow other channel operations to happen while the channel is bridged. ARI channel operations are designed to queue up and execute sequentially. This meant, though, that while a channel was bridged, any other channel operations would queue up and execute only after the channel left the bridge. This patch changes ARI bridging so that channel commands can execute while the channel is bridged. For most operations, things simply work as expected. The one thing that ended up being a bit odd is recording. The current recording implementation will fail when one attempts to record a channel that's in a bridge. Note that the bridge itself may be recording; it's recording a specific channel in the bridge that fails. While this is an annoying limitation, channel recording is still very useful for use cases such as voice mail, and bridge recording makes up much of the difference for other use cases.

Jonathan Rose	6fe21ef48e	bridge_channel: Support the lonely flag and make ARI use it. The lonely flag is an optional flag for bridge channels that will make them leave a bridge when a channel leaves if only lonely channels are in the bridge at that point. This is useful for things like ending recording and playback channels when they cease to be interacting with other channels in the bridge.

David M. Lee	c790848794	ARI: Add recording controls This patch implements the controls from ARI recordings. The controls are: * DELETE /recordings/live/{recordingName} - stop recording and discard it * POST /recordings/live/{recordingName}/stop - stop recording * POST /recordings/live/{recordingName}/pause - pause recording * POST /recordings/live/{recordingName}/unpause - resume recording * POST /recordings/live/{recordingName}/mute - mute recording (record silence to the file) * POST /recordings/live/{recordingName}/unmute - unmute recording. Since this underlying functionality did not already exist, is was added to app.c by a set of control frames, similar to how playback control works. The pause/mute control frames are toggles, even though the ARI controls are idempotent, to be consistent with the playback control frames.

David M. Lee	357b275239	Fix res_ari_asterisk load issue The new res_ari_asterisk.so module presents several config options from asterisk main. Unfortunately, they aren't exported, so the module won't load on Linux. This patch renames the variables, adding the ast_ prefix so they will be exported.

David M. Lee	5114e4fc0b	ARI - GET /ari/asterisk/info This patch adds basic system information access to ARI. The results are roughly what you get from 'core show settings', with a few minor differences. * Data is structured, with 'build', 'system', 'config' and 'status' sub-objects. * Each sub-object is selectable, using the ?only= parameter. A comma separated list can be provided to select multiple sections. * A few config options are numeric, for which 0 means 'unlimited'. Instead of having a special interpretation of those fields, they are simply omitted if they're 0. * The information is limited to what might be useful to building external applications.

David M. Lee	537ecebd2d	ARI - implement allowMultiple for parameters Swagger allows parameters to be specified as 'allowMultiple', meaning that the parameter may be specified as a comma separated list of values. I had written some of the API docs using that, but promptly forgot about implementing it. This patch finally fills in that gap. The codegen template was updated to represent 'allowMultiple' fields as array/size fields in the _args structs. It also parses the comma separated list using ast_app_separate_args(), so quoted strings in the argument will be handled properly.

David M. Lee	10c91bc96e	Address JSON thread safety issues. In tracking down some unit tests failures, I ended up reading the fine print[1] regarding Jansson's thread safety. In short: 1. Ref-counting is non-atomic. 2. json_dumps() and friends are not thread safe. This patch adds locking where necessary to our ast_json_* wrapper API, with documentation in json.h describing the thread safety limitations of the API.

David M. Lee	e1b959ccbb	Split caching out from the stasis_caching_topic. In working with res_stasis, I discovered a significant limitation to the current structure of stasis_caching_topics: you cannot subscribe to cache updates for a single channel/bridge/endpoint/etc. To address this, this patch splits the cache away from the stasis_caching_topic, making it a first class object. The stasis_cache object is shared amongst individual stasis_caching_topics that are created per channel/endpoint/etc. These are still forwarded to global whatever_all_cached topics, so their use from most of the code does not change. In making these changes, I noticed that we frequently used a similar pattern for bridges, endpoints and channels: single_topic ----------------> all_topic ^ \| single_topic_cached ----+----> all_topic_cached \| +----> cache This pattern was extracted as the 'Stasis Caching Pattern', defined in stasis_caching_pattern.h. This avoids a lot of duplicate code between the different domain objects. Since the cache is now disassociated from its upstream caching topics, this also necessitated a change to how the 'guaranteed' flag worked for retrieving from a cache. The code for handling the caching guarantee was extracted into a 'stasis_topic_wait' function, which works for any stasis_topic.
