<pre style="margin: 0; padding: 0; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">Richard had a shopping list of improvements to be made. Here is the copypasta.
1) Support for ${LIMIT_CONNECT_FILE} is missing. This file is played at
the beginning of the bridge. This can be implemented as a one time
interval hook with an immediate timeout that fires as soon as the channel
joins the bridge.
* Addressed as described. It's worth noting that contrary to documentation,
normal Asterisk doesn't actually say the remaining time at the beginning of the
conference if no LIMIT_CONNECT_FILE is specified. This patch changes things to
match with the documentation.
2) The interval_hook_time_cmp() needs to compare a sequence number of the
order of hooks added in addition to the interval_trip_time. This will
ensure that when timeouts happen at the same time, the oldest interval
expiring at that time will execute first.
* Implemented as suggested.
3) Need to add the test events associated with interval hooks. Notably
the end bridge timeout event. There may be other timeout events that I am
not aware of.
* Added to the limits duration callback. The other relevant test event was
for the S option and for L with only the duration argument, and they are
currently executed through a different mechanism that is unaffected by this
work. That might be changed soon.
4) ast_bridge_features_set_limits() must not save a pointer to the limits
struct in the hook. In this case the peer channel will likely have a
stale pointer when ast_bridge_call() is changed to not expect to get the
peer back. Also transfers could move the peer channel to another bridge.
ast_bridge_features_set_limits() should copy the limits information into
its own structure so it is independent.
* ast_bridge_features_set_limits now copies the contents of the limits
struct into a freshly allocated struct and applies it to the bridge channel's
features struct. Only one can be applied to a bridge channel at a time right
now and I'm unsure if that should be changed or if a mechanism for overwriting
it should be provided.
5) I think it is a good feature of the interval hooks to know about the
"timeleft" macro sound filename. This allows the LIMIT_CONNECT_FILE and
LIMIT_WARNING_FILE to be set to "timeleft" and get the time left output.
* timeleft macro sound name is now read by the hook rather than reinterpreted
at the consumer level.
6) I don't particularly like the fact that struct
ast_bridge_features_limits has fixed sized sound filenames.
* Changed to use string fields. It might still be limited from a practical
standpoint by the dial application and/or features.c.
7) I don't think that ast_bridge_features_interval_hook() needs to have a
strict flag. It should always do that if it is a repeating interval.
* Strict flag removed and all intervals are now treated strictly.</pre>
