[Kimchi-devel] [PATCH] AsyncTask: Propagate cherrypy request information to worker threads

From: Zhou Zheng Sheng <zhshzhou(a)linux.vnet.ibm.com&gt; cherrypy.request is a proxy for cherrypy.serving.request, and cherrypy.serving stores the request information on the thread local storage. When new threads created by Kimchi code, the related request information is not propagated to the new threads. The problem is that exception message translation code needs the Accept-Language header or session cookie to determine which language the user speaks. If the request information is missing, it assumes the language is English. Usually this is not a problem because most of the threads in Kimchi just run in background, and the exception message is written to log, so English in log is OK. However the AsyncTask catches the exception in thread and reports to the front-end, and this is not friendly to the user without proper translation. This patch propagates the request information to the new threads started by the AsyncTask, so exception message gets translated according to the request header or session cookie.
