Subject: taskprocessors: Improve logging and add new cli options
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=f29ce05e3e5262a2040e86e89f98638453b032e0;p=thirdparty%2Fasterisk.git

taskprocessors: Improve logging and add new cli options

This change makes some small changes to improve log readability in
addition to the following changes:

Modified 'core show taskprocessors' to now show Low time and High time
for task execution.

New command 'core show taskprocessor name <taskprocessor-name>' to dump
taskprocessor info and current queue.

Addionally, a new test was added to demonstrate the 'show taskprocessor
name' functionality:
test execute category /main/taskprocessor/ name taskprocessor_cli_show

Setting 'core set debug 3 taskprocessor.c' will now log pushed tasks.
(Warning this is will cause extremely high levels of logging at even
low traffic levels.)

Resolves: #1566

UserNote: New CLI command has been added -
core show taskprocessor name <taskprocessor-name>
