[asterisk-dev] Attended transfers in queue_log

[Mark Michelson]

I just finished merging a change into the trunk branch which corrects a 
long-standing deficiency of the queue_log: the inability to log attended transfers.

A bit of background: prior to the merge, a blind transfer made by a queue member 
would show up in the queue_log as a TRANSFER event. Attended transfers, however, 
due to the limitations of what information was available to app_queue, did not 
log a TRANSFER event. Instead, they appeared as a COMPLETECALLER event. With the 
recent addition of a "fixup" phase to datastores during channel masquerades, I 
realized that this could facilitate a means by which to correctly log an 
attended transfer in the queue_log. Yesterday, I created a branch to make this a 
reality and this morning I merged the branch into trunk.

Now the question arises: should this change also be merged into 1.4? My thinking 
is that the majority of users would be very happy to see attended transfers 
properly logged in the queue_log. The big thing holding me back right now is 
that there are many third-party applications that use the data in the queue_log 
to generate statistics. While I don't know of the specifics of these 
applications' internals, I know that any sort of change to what is expected may 
cause problems. To any who have written such apps, would such a change cause a 
problem? Would it actually be helpful? Thanks in advance for your replies.
