Steve Murphy	9836efb5fb	This commit closes bug 7605, and half-closes 7638. The AEL code has been redistributed/repartitioned to allow code re-use both inside and outside of Asterisk. This commit introduces the utils/conf2ael program, and an external config-file reader, for both normal config files, and for extensions.conf (context, exten, prio); It provides an API for programs outside of asterisk to use to play with the dialplan and config files. ... git-svn-id: https://origsvn.digium.com/svn/asterisk/trunk@79595 65c4cc65-6c06-0410-ace0-fbb531ad65f3	2007-08-15 19:21:27 +00:00

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	2007-08-10 16:24:11 +00:00

Steve Murphy	0e969271ae	After some study, thought, comparing, etc. I've backed out the previous universal mod to make ast_flags a 64 bit thing. Instead, I added a 64-bit version of ast_flags (ast_flags64), and 64-bit versions of the test-flag, set-flag, etc. macros, and an app_parse_options64 routine, and I use these in app_dial alone, to eliminate the 30-option limit it had grown to meet. There is room now for 32 more options and flags. I was heavily tempted to implement some of the other ideas that were presented, but this solution does not intro any new versions of dial, doesn't have a different API, has a minimal/zero impact on code outside of dial, and doesn't seriously (I hope) affect the code structure of dial. It's the best I can think of right now. My goal was NOT to rewrite dial. I leave that to a future, coordinated effort. ... git-svn-id: https://origsvn.digium.com/svn/asterisk/trunk@75983 65c4cc65-6c06-0410-ace0-fbb531ad65f3	2007-07-19 23:24:27 +00:00
