From 4f45f9bb59b86410a0f872899d1a66d6e1a520c8 Mon Sep 17 00:00:00 2001 From: Julien Desfossez Date: Tue, 31 Jan 2017 13:12:38 -0500 Subject: [PATCH] debug-info filter plugin MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit This plugin can be inserted in the graph to add the debugging informations to events that have the necessary context informations (see the README for usage informations). Compared to the previous implementation, this version does not only output the debug informations to the text output, but it adds the debug_info structure into the CTF events. That way, the plugins and sinks after this one see the debug_info as part of the event contexts. The default name of the structure added to the events is "debug_info", but can be overridden. If this structure already exists in the event context, it is not added again. If a trace does not have the ip and vpid event contexts in its stream class, the trace is copied without adding the "debug_info" structure.
