From 058a96ed506d77714bcce3d69b351e364078c080 Mon Sep 17 00:00:00 2001 From: Harsh Prateek Bora Date: Wed, 21 Dec 2011 12:37:23 +0530 Subject: [PATCH] scripts/analyse-9p-simpletrace.py: Add symbolic names for 9p operations. Currently, we just print the numerical value of 9p operation identifier in case of RERROR which is less meaningful for readability. Mapping 9p operation ids to symbolic names provides a better tracelog: RERROR (tag = 1 , id = TWALK , err = " No such file or directory ") RERROR (tag = 1 , id = TUNLINKAT , err = " Directory not empty ") This patch provides a dictionary of all possible 9p operation symbols mapped to their numerical identifiers which are likely to be used in future at various places in this script.
