<p>George Joseph has uploaded this change for <strong>review</strong>.</p><p><a href="https://gerrit.asterisk.org/c/asterisk/+/14728">View Change</a></p><pre style="font-family: monospace,monospace; white-space: pre-wrap;">Scope Trace: Make it easier to trace through synchronous tasks<br><br>Tracing through synchronous tasks was a little troublesome because<br>the new thread's stack counter reset to 0. This change allows<br>a synchronous task to set its trace level to be the same as the<br>thread that pushed the task. For now, the task's level has to be<br>passed in the task's data structure but a future enhancement to the<br>taskprocessor subsystem could automatically set the trace level<br>of the servant to be that of the caller.<br><br>This doesn't really make sense for async tasks because you never<br>know when they're going to run anyway.<br><br>Change-Id: Ib8049c0b815063a45d8c7b0cb4e30b7b87b1d825<br>---<br>M include/asterisk/logger.h<br>M main/logger.c<br>2 files changed, 108 insertions(+), 19 deletions(-)<br><br></pre><pre style="font-family: monospace,monospace; white-space: pre-wrap;">git pull ssh://gerrit.asterisk.org:29418/asterisk refs/changes/28/14728/1</pre><pre style="font-family: monospace,monospace; white-space: pre-wrap;"><span>diff --git a/include/asterisk/logger.h b/include/asterisk/logger.h</span><br><span>index 67e4df7..5514d83 100644</span><br><span>--- a/include/asterisk/logger.h</span><br><span>+++ b/include/asterisk/logger.h</span><br><span>@@ -641,14 +641,16 @@</span><br><span> AST_TRACE_INDENT_DEC_BEFORE,</span><br><span> /*!
