When I initially released this project, I released it under my own copyright. I have since then worked on it in my 20% time at Google (and want to continue doing this) and my life becomes much simpler if the copyright is Google's. From the perspective of how this project is run and managed, **NOTHING** changes. YCM is not a Google product, merely a project run by someone who just happens to work for Google. Please note that the license of the project is **NOT** changing. People sending in future pull requests will have to sign the Google [CLA](https://developers.google.com/open-source/cla/individual) (you can sign online at the bottom of that page) before those pull requests could be merged in. People who sent in pull requests that were merged in the past will get an email from me asking them to sign the CLA as well.

# This class implements the Bottle plugin API:
|
|
# http://bottlepy.org/docs/dev/plugindev.html
|
|
#
|
|
# The idea here is to decorate every route handler automatically so that on
|
|
# every request, we log when the request was made. Then a watchdog thread checks
|
|
# every check_interval_seconds whether the server has been idle for a time
|
|
# greater that the passed-in idle_suicide_seconds. If it has, we kill the
|
|
# server.
|
|
#
|
|
# We want to do this so that if something goes bonkers in Vim and the server
|
|
# never gets killed by the client, we don't end up with lots of zombie servers.
